EJNMMI Res 2025; 15:22. [PMID: 40082314 PMCID: PMC11906962 DOI: 10.1186/s13550-025-01218-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2025] [Accepted: 03/07/2025] [Indexed: 03/16/2025] Open
Abstract
BACKGROUND Early detection and treatment are critical for improving the survival and prognosis of patients with cervical cancer. However, there is a notable scarcity of targeted imaging probes specifically designed to detect high-grade squamous intraepithelial lesions (HSIL) and cervical cancer. Our study aimed to address this gap by identifying and validating a targeted imaging probe for these conditions. RESULTS Using bioinformatics data, we identified galectin-7 (GAL7) as highly expressed in patients with cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC). Immunohistochemical staining of biopsy samples from 30 HSIL and cervical cancer patients verified the high and specific expression of GAL7. Further validation was performed using mouse and human CESC cell lines and tumor xenografts, confirming the consistent expression of GAL7. Based on this finding, we synthesized a GAL7-specific antibody conjugated with FITC, creating the GAL7-FITC fluorescence imaging probe. Fluorescence molecular imaging revealed that GAL7-FITC exhibited specific binding to various CESC cell lines and xenograft mouse models. Additionally, the diagnostic capability of GAL7-FITC was demonstrated in fresh HSIL specimens from cervical cone excisions, validated through histopathology and immunohistochemical analysis. CONCLUSIONS Our study identified GAL7 as a specific target for CESC and successfully developed the GAL7-FITC fluorescence imaging probe. GAL7-FITC has shown promising potential for clinical application in the early detection of HSIL and CESC, providing rapid fluorescence imaging diagnosis without observable toxicity. This advancement may significantly enhance the accuracy and speed of cervical cancer diagnostics, ultimately improving patient outcomes.

[PMID: 39773621 PMCID: PMC11708263 DOI: 10.1186/s12885-024-13419-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2024] [Accepted: 12/31/2024] [Indexed: 01/11/2025] Open
Abstract
BACKGROUND N6-methyladenosine (m6A) methylation plays a key role in tumor progression. However, the significance of methyltransferase-like 3 (METTL3) in biological processes of soft tissue sarcoma (STS) patients, and the relationship between METTL3 and STS are unclear. METHODS The expression of METTL3 in STS and its relationship with patient prognosis were determined from database analyses. Immunohistochemical staining and 18F-FDG radioautography were performed on tumor tissues from 39 patients with STS undergoing 18F-FDG PET before treatment. METTL3 expression in tumor and peritumoral tissues was evaluated with the Wilcoxon test. The Mann-Whitney U test and Spearman's correlation analysis were used to explore correlations of METTL3 expression with both clinicopathological characteristics and 18F-FDG uptake. One-way analysis of variance and ROC analysis were used to evaluate the efficacy of 18F-FDG PET metabolic parameters in predicting METTL3 expression. RESULTS METTL3 expression was significantly higher in STS tumor tissues than normal tissues (all p values<0.01), and correlated with poor patient prognosis (p < 0.05). METTL3 expression was associated with histological differentiation (Z=-2.026, p = 0.043), but no significant difference was observed according to age, sex, tumor size, tumor location, or metastasis (all p values > 0.05). METTL3 expression positively correlated with the expression of CD163 (r = 0.502, p = 0.011), CD68 (r = 0.381, p = 0.017), and CD8 (r = 0.319, p = 0.048), and exhibited a trend toward correlation with CD4 expression (r = 0.310, p = 0.055). Moreover, 18F-FDG metabolism positively correlated with METTL3 expression in STS (r = 0.580 for PET and r = 0.434 for radioautography, all p values<0.01). The SUVmax of PET was significantly higher in tumors with high rather than low METTL3 expression (Z=-2.979, p = 0.003). CONCLUSIONS METTL3 was overexpressed in STS, which may be a meaningful target of action in STS patients. The 18F-FDG uptake was significantly elevated in tumors with high METTL3 expression, SUVmax could provide a meaningful imaging biomarker for its expression.

Abstract
Human gut microbiota plays a crucial role in health and disease. Infancy is a critical period for gut microbiota maturation and immune system development and has the potential to affect long-term health. Understanding the development of gut microbiota in Japanese children is essential because of regional differences and the long-term health effects of the early gut microbiota. However, while several longitudinal studies in Japan have explored the development of the gut microbiota after birth, more extended follow-up periods are still needed. In this study, we aimed to analyze the gut microbiota of 106 Japanese mother-child pairs from the Chiba Study of Mother and Child Health, Japan, over 3.5 years. The results showed that the alpha diversity of the gut microbiota in children increased with age, and its composition began to resemble that of adults. We identified four distinct clusters of gut microbiota that reflected different maturation stages. The similarity between the maternal and child gut microbiota appeared to follow a bimodal-like distribution, suggesting that the presence of older siblings may enhance this similarity. This study highlights the dynamic nature of gut microbiota development in Japanese children and deepens our understanding of the similarities between maternal and child gut microbiota.

Abstract
Alhagi-honey (AH) is a well-established traditional ethnic medicine with advantageous effects against diarrhea and headaches. We aimed to explore the preventive effect of AH on liver damage induced by heat stress (HS) and its underlying mechanism. HS models were established by thermostat, and mice were treated at 39 ℃ for 10 h, lasting for 7 days. Hematoxylin-eosin (H&E) staining and Periodic Acid-Schiff (PAS) staining were used for histological observation, and transmission electron microscopy (TEM) was used for ultrastructure examination of hepatocytes. Gut microbiota (GM) composition and liver metabolites were respectively analyzed by 16S rRNA sequencing and non-targeted metabolome sequencing. AH pretreatment alleviated liver damage caused by heat stress in mice. The main manifestation was that AH alleviated serum aspartate transferase (AST) and aspartate transaminase (ALT). It was found that AH improved symptoms of hepatocyte damage. In addition, the relative abundance of f_Rikenellaceae, g_Incertae_Sedis and s_Staphylococcus_Orisratti, g_Lachnoclostridium, g_GCA-900066575, and s_Alistipes_inops were modified by AH and these bacterial genera showed association with 6 metabolites (2- (3,4-dihydroxyphenyl) acetamide, 3-hydroxy-3-methylpentanedioic acid, PC (17:0/17:1), Y-L-Glutamy-L-glutamic acid, L-Isoleucine, 5-Methyluridine, 8,8-dimethyl-2-phenyl-4H,8H-pyrano [2, 3-h] chromen-4-one). The Pearson analysis also showed a strong correlation between these microbes and 2 risk indicators (AST and ALT) of liver damage. AH alleviated HS-induced liver damage by regulating liver metabolism and maintaining normal GM. It demonstrated that AH held potential as a prophylactic drug for the prevention of HS-induced liver damage.

Saudi J Gastroenterol 2024; 30:335-341. [PMID: 39175281 PMCID: PMC11534187 DOI: 10.4103/sjg.sjg_122_24] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Revised: 07/12/2024] [Accepted: 08/02/2024] [Indexed: 08/24/2024] Open
Abstract
BACKGROUND A recent name change of nonalcoholic fatty liver disease (NAFLD) or metabolic dysfunction-associated fatty liver disease (MAFLD) to metabolic dysfunction-associated steatotic liver disease was primarily driven by potential stigma associated with the terminology. This stigma can be different between patients and healthcare providers and differ according to geographic regions of the world. Our aim was to better understand stigma and disease burden among patients with NAFLD enrolled in the global survey from Saudi Arabia (SA). METHODS Members of the Global NASH Council created a 68-item survey about patients' experience with NAFLD, covering history of stigmatization and discrimination due to the disease, various aspects of the disease burden [(Liver Disease Burden (LDB), 35 items, 7 domains], and perception of various diagnostic terms for NAFLD. Patients whose country of residence was SA were asked to complete the survey. RESULTS The survey was completed by 804 patients with NAFLD from SA. Of all enrolled patients, 17% ever disclosed having NAFLD/nonalcoholic steatohepatitis (NASH) to family/friends. The most commonly used term for the disease was "fatty liver" (96% used it at least sometimes, 79% frequently or always). There were 3.7% who reported experiencing stigma or discrimination (at least sometimes) due to obesity/overweight versus only 2.7% due to NAFLD. Female patients reported a history of stigmatization or discrimination more frequently than males: 5.9% versus 3.0% due to obesity ( P = 0.06) and 5.4% versus 1.8% due to NAFLD ( P = 0.01). There were 43% of patients who reported ever missing or avoiding a visit to a primary care provider due to NAFLD (48% male vs 28% female, P < 0.0001). The greatest social-emotional burden among patients with NAFLD (by LDB) was being or being identified as a person with liver disease (10% agree, 4% male vs 26% female) and feeling like they could not do anything about their liver disease (6.4% agree, 3% male vs 16% female). Regarding how patients perceived diagnostic terms, there were no substantial differences between "fatty liver disease", "NAFLD", "NASH", and "MAFLD". CONCLUSION Stigmatization in terms of disease burden, disease-related stigma, and perception of various diagnostic terms are rarely observed in patients with NAFLD in SA. In comparison to male patients, female patients with NAFLD reported more commonly a history of stigmatization and discrimination and a significantly greater disease burden. The findings will help inform policymakers to develop programs to increase awareness and provide education about stigma related to NAFLD.

Abstract
Polyethylene microplastics (PE MPs) have sparked widespread concern about their possible health implications because of their abundance, pervasiveness in the environment and in our daily life. Multiple investigations have shown that a high dosage of PE MPs may adversely impact gastrointestinal health. In tandem with the rising prevalence of Inflammatory bowel disease (IBD) in recent decades, global plastic manufacturing has risen to more than 300 million tons per year, resulting in a build-up of plastic by-products such as PE MPs in our surroundings. We have explored current advancements in the effect PE MPs on IBD in this review. Furthermore, we compared and summarized the detrimental roles of PE MPs in gut microbiota of different organisms viz., earthworms, super worm's larvae, yellow mealworms, brine shrimp, spring tails, tilapia, gilt-head bream, crucian carp, zebrafish, juvenile yellow perch, European sea bass, c57BL/6 mice and human. According to this review, PE MPs played a significant role in decreasing the diversity of gut microbiota of above-mentioned species which leads to the development of IBD and causes severe intestinal inflammation. Finally, we pinpoint significant scientific gaps, such as the movement of such hazardous PE MPs and the accompanying microbial ecosystems and propose prospective research directions.

Abstract
BACKGROUND Cap-mounted-clips, especially Over-The-Scope-Clip (OTSC™), are recommended for recurrent nonvariceal upper gastrointestinal bleeding (NVUGIB). There has been recent interest in their use as an initial hemostatic modality. We performed a systematic review of randomized controlled trials (RCTs) assessing cap-mounted clips' efficacy as a primary hemostatic modality in NVUGIB. METHODS A literature search of MEDLINE, EMBASE, and ISI Web of Science databases up to April 2024 identified RCTs comparing cap-mounted clips to standard endoscopic therapy (SET) as a primary hemostatic modality in NVUGIB. The primary endpoint was the composite outcome of further bleeding (persistent or recurrent) at 30 days. Secondary outcomes included persistent bleeding at index endoscopy and 30-day rebleeding, individually. Other pertinent outcomes were also recorded. A meta-analysis was performed to determine pooled risk ratios (RRs), comparing cap-mounted clip to SET. Out of 516 citations, five RCTs (n = 555), all assessing OTSC™, were included. RESULTS The composite outcome of further bleeding was lower with cap-mounted clip versus SET (RR = 0.33 [95% confidence interval {CI}: 0.20-0.54]). There was no difference in persistent bleeding at initial endoscopy (RR = 0.30 [95% CI: 0.07-1.30]), but 30-day rebleeding was lower with cap-mounted clip (RR = 0.38 [95% CI: 0.21-0.70]). There were no differences in other outcomes. Grading of the evidence ranged from very low to moderate, mainly due to risk of bias and imprecision. CONCLUSIONS Cap-mounted clips may be an efficacious primary hemostatic modality, associated with a lower further bleeding at 30 days compared to SET in NVUGIB. However, due to limitations in existing evidence, further research must better characterize an optimal subgroup of patients benefiting most from this approach before adopting its routine use.

Abstract
ABSTRACT Climate change is an existential threat to humanity. While the healthcare sector must manage the health-related consequences of climate change, it is a significant contributor to greenhouse gas emissions, responsible for up to 4.6% of global emission, aggravating global warming. Within the hospital environment, the three largest contributors to greenhouse gas emissions are the operating theatre, intensive care unit and gastrointestinal endoscopy. Knowledge of the health-related burden of climate change and the potential transformative health benefits of climate action is important to all health professionals, as they play crucial roles in effecting change. This article summarises the available literature on the impact of healthcare on climate change and efforts in mitigation, focusing on the intrinsic differences and similarities across the operating theatre complex, intensive care unit and gastrointestinal endoscopy unit. It also discusses strategies to reduce carbon footprint.

Abstract
BACKGROUND Cardiovascular disease commonly affects advanced liver disease patients. They undergo cardiac interventions to improve cardiac outcomes. Cirrhosis increases complication risk, including bleeding, renal and respiratory failure, and further decompensation, including death, posing a clinical dilemma to proceduralists. Predicting outcomes is crucial in managing patients with cirrhosis. Our aim was to systematically review clinical parameters to assess the mortality and complication risk in patients with cirrhosis undergoing cardiac interventions. METHODS We searched cirrhosis and cardiovascular intervention terminology in PubMed and Excerpta Medica Database (EMBASE) from inception to January 8, 2023. We included studies reporting clinical scores (e.g. Model for End-stage Liver Disease (MELD), Child-Pugh-Turcotte (CPT), cardiovascular interventions, mortality, and morbidity outcomes). We independently abstracted data from eligible studies and performed qualitative summaries. RESULTS Eight studies met the inclusion criteria. Procedures included tricuspid valve surgery, catheterization-related procedures, aortic valve replacement (AVR), pericardiectomy, and left ventricular assist device (LVAD) placement. MELD primarily predicted mortality (n = 4), followed by CPT (n = 2). Mortality is significantly increased for MELD > 15 after tricuspid valve surgery. Albumin, creatinine, and MELD were significantly associated with increased mortality after transcatheter AVR (TAVR), although specific values lacked stratification. CPT was significantly associated with increased mortality after cardiac catheterization or pericardiectomy. In LVAD placement, increasing MELD increased the unadjusted odds for perioperative mortality. CONCLUSIONS Our systematic review showed that clinical parameters predict mortality and morbidity risk in patients with cirrhosis undergoing cardiac procedures.

Abstract
Functional constipation is one of the most common gastrointestinal disorders. Oxidative stress can aggravate organ dysfunction. Enteric neurotransmitters have significant effects on the regulation of the enteric nervous system and intestinal muscle contraction. Oxidative stress and reduced gastrointestinal motility are considered to be one of the main causes of constipation. This study aimed to investigate whether LimosiLactobacillus pentosus CQZC02 alleviated loperamide hydrochloride (Lop)-induced constipation in mice under high-fat diet (HFD) conditions and to elucidate the underlying mechanism, focusing on enteric neurotransmitters. Four-week-old female BALB/c mice were randomly divided into five groups: normal group (Nor), constipation model group (H-Lop), L. pentosus CQZC02 low-dose group (H-Lop + ZC02L), L. pentosus CQZC02 high-dose group (H-Lop + ZC02H), and LimosiLactobacillus bulgaricus control group (H-Lop + LB). The fecal weight, water content, and total gastrointestinal transit time were measured to determine whether the mice were constipated. Small bowel and colon tissue damage was assessed by hematoxylin and eosin staining, while the degree of damage was determined by double-blind scoring. The levels of serum oxidative stress markers malondialdehyde, superoxide dismutase, glutathione peroxidase, and catalase and neurotransmitters motilin, gastrin, substance P, endothelin, somatostatin, and vasoactive intestinal peptide were measured. The gene expression levels of endothelial nitric oxide synthase, inducible nitric oxide synthase, neuronal nitric oxide synthase, nuclear factor kappa-B, and cyclooxygenase-2 in small intestine tissue were calculated. The constipation symptoms of mice in H-Lop group were manifested by a variety of physiological indicators. In addition, compared with the H-Lop group, H-Lop + ZC02H could effectively relieve the symptoms of constipation in mice. In symptom characterization, the mice in the H-Lop + ZC02H group lost weight and increased feces and water content. In functional experiments, gastrointestinal motility was enhanced; the inflammation score of intestinal tissue was decreased, and gene expression levels were modulated; serum oxidative factor levels were modulated, and oxidative stress levels were decreased.

Front Immunol 2023; 14:1162473. [PMID: 37622114 PMCID: PMC10445157 DOI: 10.3389/fimmu.2023.1162473] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Accepted: 07/17/2023] [Indexed: 08/26/2023] Open
Abstract
Background Crohn's disease (CD) has an increasing incidence and prevalence worldwide. It is currently believed that both the onset and progression of the disease are closely related to immune system imbalance and the infiltration of immune cells. The aim of this study was to investigate the molecular immune mechanisms associated with CD and its fibrosis through bioinformatics analysis. Methods Three datasets from the Gene Expression Omnibus data base (GEO) were downloaded for data analysis and validation. Single sample gene enrichment analysis (ssGSEA) was used to evaluate the infiltration of immune cells in CD samples. Immune cell types with significant differences were identified by Wilcoxon test and Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis. Differentially expressed genes (DEGs) were screened and then subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) functional correlation analysis, as well as protein-protein interaction (PPI) network analysis. The cytoHubba program and the GSE75214 dataset were used to screen for hub genes and plot Receiver operating characteristic (ROC)curves to screen for possible biomarkers of CD based on diagnostic efficacy. The hub genes of CD were correlated with five significantly different immune cells. In addition, validation was performed by real time quantitative PCR (RT-qPCR) experiments in colonic tissue of CD intestinal fibrosis rats to further identify hub genes that are more related to CD intestinal fibrosis. Results The DEGs were analyzed separately by 10 algorithms and narrowed down to 9 DEGs after taking the intersection. 4 hub genes were further screened by the GSE75214 validation set, namely COL1A1, CXCL10, MMP2 and FGF2. COL1A1 has the highest specificity and sensitivity for the diagnosis of CD and is considered to have the potential to diagnose CD. Five immune cells with significant differences were screened between CD and health controls (HC). Through the correlation analysis between five kinds of immune cells and four biomarkers, it was found that CXCL10 was positively correlated with activated dendritic cells, effector memory CD8+ T cells. MMP2 was positively correlated with activated dendritic cells, gamma delta T cells (γδ T) and mast cells. MMP2 and COL1A1 were significantly increased in colon tissue of CD fibrosis rats. Conclusion MMP2, COL1A1, CXCL10 and FGF2 can be used as hub genes for CD. Among them, COL1A1 can be used as a biomarker for the diagnosis of CD. MMP2 and CXCL10 may be involved in the development and progression of CD by regulating activated dendritic cell, effector memory CD8+ T cell, γδ T cell and mast cell. In addition, MMP2 and COL1A1 may be more closely related to CD intestinal fibrosis.

Abstract
BACKGROUND Pancreatic endocrine insufficiency is more likely to occur after acute pancreatitis (AP), but the risk factors affecting pancreatic endocrine function remain controversial. Therefore, exploring the incidence and risk factors of fasting hyperglycaemia following first-attack AP is important. METHODS Data were collected from 311 individuals with first-attack AP without previous diabetes mellitus (DM) or impaired fasting glucose (IFG) history treated in the Renmin Hospital of Wuhan University. Relevant statistical tests were performed. A two-sided p-value < 0.05 was considered statistically significant. RESULTS The incidence of fasting hyperglycaemia in individuals with first-attack AP was 45.3%. Univariate analysis showed that age (χ2 = 6.27, P = 0.012), aetiology (χ2 = 11.184, P = 0.004), serum total cholesterol (TC) (χ2 = 14.622, P < 0.001), and serum triglyceride (TG) (χ2 = 15.006, P < 0.001) were significantly different between the hyperglycaemia and non-hyperglycaemia groups (P < 0.05). The serum calcium concentration (Z=-2.480, P = 0.013) was significantly different between the two groups (P < 0.05). Multiple logistic regression analysis showed that age- ≥60 years (P < 0.001, OR = 2.631, 95%Cl = 1.529-4.527) and TG ≥ 5.65 mmol/L (P < 0.001, OR = 3.964, 95%Cl = 1.990-7.895) were independent risk factors for fasting hyperglycaemia in individuals with first-attack AP (P < 0.05). CONCLUSIONS Old age, serum triglycerides, serum total cholesterol, hypocalcaemia, and aetiology are associated with fasting hyperglycaemia following first-attack AP. Age ≥ 60 years and TG ≥ 5.65 mmol/L are independent risk factors for fasting hyperglycaemia following first-attack AP.

Abstract
Aquatic organisms such as fish can accumulate high concentrations of arsenic (As), which has toxic effects on fish. However, whether the intestinal flora are involved in As damage to fish intestinal tissues and the underlying process are unclear. Common carp (Cyprinus carpio) were exposed to As (2.83 mg/L) in water for 30 days, and blood, muscle, intestine, and intestine samples were collected. Intestinal pathological sections were observed, and the lipopolysaccharide (LPS) levels in serum and the levels of As accumulation and tight junction-related factors in intestinal tissues were measured. The gut microbiota was analysed by 16S rRNA sequencing. The results showed that As treatment decreased the abundance of microbiota, increased the number of harmful bacteria, and decreased the number of beneficial bacteria in the intestine. In our experiment, the top 30 harmful and beneficial bacteria with the highest relative abundance were identified. Among the top 30 harmful and beneficial bacteria, As treatment resulted in a significant (P < 0.05) increase in harmful bacteria (such as Fusobacteriota, Bacteroidota (LPS-producing bacteria), Verrucomicrobiota, Bacteroides, Aeromonas, and Stenotrophomonas) and a significant (P < 0.05) decrease in beneficial bacteria (such as Actinobacteriota, Planctomycetota, Firmicutes, Reyranella, Akkermansia, and Pseudorhodobacter), which further demonstrated that As affects the abundance of intestinal flora. In addition, As exposure increased the LPS level in serum and the abundance of Bacteroidota (LPS-producing bacteria) in the intestine. Bacteroidota exhibits the six highest relative abundance at the phylum level, which indicates that LPS produced by Bacteroidota can increase the LPS level in serum. Additionally, the protein and gene levels of the tight junction markers ZO-1 and occludin in the intestine were reduced by As treatment, which further indicated that As exposure impaired the structural integrity of the intestine. In conclusion, the results obtained in our study indicate that the intestinal flora, LPS, and tight junctions participate in the impairment of the structural integrity of the common carp intestine resulting from As exposure.

Abstract
Background The RNA modification 5-methylcytosine (m5C) is one of the most prevalent post-transcriptional modifications, with increasing evidence demonstrating its extensive involvement in the tumorigenesis and progression of various cancers. Colorectal cancer (CRC) is the third most common cancer and second leading cause of cancer-related deaths worldwide. However, the role of m5C modulators in shaping tumor microenvironment (TME) heterogeneity and regulating immune cell infiltration in CRC requires further clarification. Results The transcriptomic sequencing data of 18 m5C regulators and clinical data of patients with CRC were obtained from The Cancer Genome Atlas (TCGA) and systematically evaluated. We found that 16 m5C regulators were differentially expressed between CRC and normal tissues. Unsupervised cluster analysis was then performed and revealed two distinct m5C modification patterns that yielded different clinical prognoses and biological functions in CRC. We demonstrated that the m5C score constructed from eight m5C-related genes showed excellent prognostic performance, with a subsequent independent analysis confirming its predictive ability in the CRC cohort. Then we developed a nomogram containing five clinical risk factors and the m5C risk score and found that the m5C score exhibited high prognostic prediction accuracy and favorable clinical applicability. Moreover, the CRC patients with low m5C score were characterized by "hot" TME exhibiting increased immune cell infiltration and higher immune checkpoint expression. These characteristics were highlighted as potential identifiers of suitable candidates for anticancer immunotherapy. Although the high m5C score represented the non-inflammatory phenotype, the CRC patients in this group exhibited high level of sensitivity to molecular-targeted therapy. Conclusion Our comprehensive analysis indicated that the novel m5C clusters and scoring system accurately reflected the distinct prognostic signature, clinicopathological characteristics, immunological phenotypes, and stratifying therapeutic opportunities of CRC. Our findings, therefore, offer valuable insights into factors that may be targeted in the development of precision medicine-based therapeutic strategies for CRC.

Abstract
The aim of our study was to investigate the main characteristics of peripheral blood NKT cell phenotype in patients with disseminated purulent peritonitis (DPP) in dynamics of postoperative period, depending on the disease outcome. Fifty-two patients with acute surgical diseases and injuries of the abdominal organs complicated by DPP, and 68 healthy individuals in control group, were examined. Blood sampling was performed before surgery (preoperative period), as well as on the day 7, 14 and 21 of postoperative period. All patients with DPP were divided into two groups depending on disease outcome in postoperative period: patients with favorable disease outcome (n = 34); and patients with unfavorable outcome (n = 18). Study of the phenotype of blood NKT lymphocytes was performed by flow cytometry using direct immunofluorescence of whole peripheral blood samples with monoclonal antibodies. The low relative and absolute level of NKT cells was observed in DPP patients regardless of outcome disease in preoperative period. At the same time, the absolute level of NKT cells returned to normal only in patients with favorable DPP outcome and only by day 21 after surgery. Patients with favorable DPP outcome by the end of examination period had normalized quantity of mature NKT-lymphocytes and significantly decreased level of cytotoxic cells which was apparently associated with migration of such cell subsets to site of inflammation. A reduced level of non-classical (expressing CD8 marker) mature and cytokine-producing NKT cells was detected only in patients with favorable DPP outcome in preoperative period which returned to normal by the end of postoperative period. At the same time, patients with unfavorable disease outcome had reduced quantity of NKT cells of these subsets by day 21 of postoperative treatment. Patients with favorable outcome had high level of mature and cytotoxic CD11b+ NKT cells already in the preoperative period, while patients with unfavorable DPP outcome had increased level of cytotoxic CD11b+ NKT cells only by day 21 after surgery. The proportion of NKT cells expressing activation markers (CD28 and CD57) was reduced in patients in preoperative period that returned to normal immediately after surgery with favorable outcome, while it recovered with unfavorable outcome closer to the end of postoperative examination. The defined features of NKT cell phenotype in patients with unfavorable DPP outcome characterize disturbances in subset ratio and mechanisms of functioning of this cell fraction. This determines a need to develop immunotherapeutic methods aimed at stimulating immunoregulatory activity of NKT cells.

Abstract
Acinar-to-ductal metaplasia (ADM) is a recently recognized, yet less well-studied, precursor lesion of pancreatic ductal adenocarcinoma (PDAC) developed in the setting of chronic pancreatitis. Through digital spatial mRNA profiling, we compared ADM and adjacent PDAC tissues from patient samples to unveil the bridging genes during the malignant transformation of pancreatitis. By comparing the bridging genes with the 7-methylguanosine (m7G)-seq dataset, we screened 19 m7G methylation genes for a subsequent large sample analysis. We constructed the “m7G score” model based on the RNA-seq data for pancreatic cancer in The Cancer Genome Atlas (TCGA) database and The Gene Expression Omnibus (GEO) database. Tumors with a high m7G score were characterized by increased immune cell infiltration, increased genomic instability, higher response rate to combined immune checkpoint inhibitors (ICIs), and overall poor survival. These findings indicate that the m7G score is associated with tumor invasiveness, immune cell infiltration, ICI treatment response, and overall patients’ survival. We also identified FN1 and ITGB1 as core genes in the m7Gscore model, which affect immune cell infiltration and genomic instability not only in pancreatic cancer but also in pan-cancer. FN1 and ITGB1 can inhibit immune T cell activition by upregulation of macrophages and neutrophils, thereby leading to immune escape of pancreatic cancer cells and reducing the response rate of ICI treatment.

Ecological and network analyses identify four microbial species with potential significance for the diagnosis/treatment of ulcerative colitis (UC). BMC Microbiol 2021; 21:138. [PMID: 33947329 PMCID: PMC8097971 DOI: 10.1186/s12866-021-02201-6] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Accepted: 04/05/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Ulcerative colitis (UC) is one of the primary types of inflammatory bowel disease (IBD), the occurrence of which has been increasing worldwide. Although IBD is an intensively studied human microbiome-associated disease, research on Chinese populations remains relatively limited, particularly on the mucosal microbiome. The present study aimed to analyze the changes in the mucosal microbiome associated with UC from the perspectives of medical ecology and complex network analysis. RESULTS In total, 56 mucosal microbiome samples were collected from 28 Chinese UC patients and their healthy family partners, followed by amplicon sequencing. Based on sequencing data, we analyzed species diversity, shared species, and inter-species interactions at the whole community, main phyla, and core/periphery species levels. We identified four opportunistic "pathogens" (i.e., Clostridium tertium, Odoribacter splanchnicus, Ruminococcus gnavus, and Flavonifractor plautii) with potential significance for the diagnosis and treatment of UC, which were inhibited in healthy individuals, but unrestricted in the UC patients. In addition, we also discovered in this study: (i) The positive-to-negative links (P/N) ratio, which measures the balance of species interactions or inhibition effects in microbiome networks, was significantly higher in UC patients, indicating loss of inhibition against potentially opportunistic "pathogens" associated with dysbiosis. (ii) Previous studies have reported conflicting evidence regarding species diversity and composition between UC patients and healthy controls. Here, significant differences were found at the major phylum and core/periphery scales, but not at the whole community level. Thus, we argue that the paradoxical results found in existing studies are due to the scale effect. CONCLUSIONS Our results reveal changes in the ecology and network structure of the gut mucosal microbiome that might be associated with UC, and these changes might provide potential therapeutic mechanisms of UC. The four opportunistic pathogens that were identified in the present study deserve further investigation in future studies.

[PMID: 33783590 DOI: 10.1007/s00203-021-02292-9] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2021] [Revised: 03/15/2021] [Accepted: 03/17/2021] [Indexed: 11/25/2022]
Abstract
Probiotics are considered valuable to human health since they improve intestinal microbial balance. Probiotics are orally taken and affect the oral microbiota, which is one of the most important parts of the human microbial community. However, there is little information on the effects of probiotics on the oral microbiota. Caries-free preschool children (N = 6) with complete deciduous dentition were enrolled and given 100 g probiotic yogurt daily for 1 year. Salivary samples were collected every 6 months and then sequenced by Illumina MiSeq system based on 16S rDNA V3-V4 hypervariable regions. The data were analyzed to obtain the changes in microbiota profiles before and after the probiotic yogurt consumption. The α diversity analysis showed that salivary microbial diversity and richness were similar between the groups. The β diversity analysis showed that salivary microbial community structure changed with the consumption of probiotic yogurt. The variation of the microbial community composition was mainly due to 9 genera; for 7 genera (Campylobacter, Haemophilus, Lautropia, Bacillus, Catonella, Lactococcus, and Solibacillus) increased, while 2 genera (Gemella, and Streptococcus) decreased. The variation of salivary microbiota structure and composition with the consumption of probiotic yogurt was revealed. This expands overall insights on the effects of probiotic products on oral microecology. It further provides a basis for predicting possible relations between probiotic interventions and oral health in preschool children.

Abstract
AIM Systematization of data on the frequency of detection of the syndrome of bacterial overgrowth in the small intestine (SIBO) in patients with functional dyspepsia (FD). MATERIALS AND METHODS MEDLINE/PubMed, EMBASE, Cochrane, Google Scholar, the Russian Science Citation Index (RSCI) through July 2020 were searched to identify studies evaluating the prevalence of SIBO in FD. In addition, a search for relevant abstracts was carried out in the electronic databases of the United European Gastroenterology Week (UEG), American College of Gastroenterology (ACG), International Conference on Nutrition and Food (ICNF). For the final analysis, publications were selected that used validated tests for the assessment of SIBO (hydrogen breath test using glucose or lactulose) with detailed descriptive statistics, allowing the resulting data to be included in the meta-analysis. RESULTS The final analysis included 7 studies with 1248 patients with FD. Overall pooled prevalence of SIBO in patients with FD was 34.73% (95% CI 24.80745.383). There was significant heterogeneity between the results (p0.0001; I2=89.91%). When excluded from the meta-analysis of a study in which the incidence of SIBO was studied in patients with refractory FD, the pooled prevalence was 38.98% (95% CI 28.96449.490). CONCLUSION This meta-analysis has demonstrated that SIBO is often associated with FD and is observed in about every third patient with this functional gastrointestinal tract disease.

Sustained Exposure to Helicobacter pylori Lysate Inhibits Apoptosis and Autophagy of Gastric Epithelial Cells. Front Oncol 2020; 10:581364.

Abstract
Helicobacter pylori is designated as a class I carcinogen of human gastric cancer following long-term infection. During this process, H. pylori bacteria persist in proliferation and death, and release bacterial components that come into contact with gastric epithelial cells and regulate host cell function. However, the impact of long-term exposure to H. pylori lysate on the pathological changes of gastric cells is not clear. In this study, we aimed to investigate the regulation and mechanisms involved in gastric cell dysfunction following continuous exposure to H. pylori lysate. We co-cultured gastric cell lines GES-1 and MKN-45 with H. pylori lysate for 30 generations, and we found that sustained exposure to H. pylori lysate inhibited GES-1 cell invasion, migration, autophagy, and apoptosis, while it did not inhibit MKN-45 cell invasion or migration. Furthermore, Mongolian gerbils infected with H. pylori ATCC 43504 strains for 90 weeks confirmed the in vitro results. The clinical and in vitro data indicated that sustained exposure to H. pylori lysate inhibited cell apoptosis and autophagy through the Nod1-NF-κB/MAPK-ERK/FOXO4 signaling pathway. In conclusion, sustained exposure to H. pylori lysate promoted proliferation of gastric epithelial cells and inhibited autophagy and apoptosis via Nod1-NF-κB/MAPK-ERK/FOXO4 signaling pathway. In the process of H. pylori-induced gastric lesions, H. pylori lysate plays as an "accomplice" to carcinogenesis.

Abstract
Exactly 30 years ago, hepatitis C virus was identified. Over the years, tremendous success has been achieved in the treatment of hepatitis C, which is currently considered to be an almost completely curable disease. The review presents the main stages in the development of hepatitis C antiviral therapy, the efficacy of various treatment regimens. The greatest progress in treatment was noted over the past 5 years when drugs with direct antiviral action appeared and began to be widely used, including in Russia, which ensure the elimination of the virus in 90-95% of cases.

Abstract
Phosphoinositide-3 kinases (PI3Ks) generate 3-phosphorylated phosphoinositide lipids that are implicated in many biological processes in homeostatic states and pathologies such as cancer, inflammation and autoimmunity. Eight isoforms of PI3K exist in mammals and among them the class I PI3K, p110γ, and PI3Kδ, and class III Vps34 being the most expressed and well characterized in immune cells. Following engagement of pathogen recognition receptors (PRRs), PI3Ks coordinate vital cellular processes of signaling and vesicular trafficking in innate phagocytes such as macrophages and professional antigen presenting dendritic cells (DCs). Although previous studies demonstrated the involvement of PI3K isoforms in innate and adaptive immune cell types, the role of PI3Ks with respect to DC biology has been enigmatic. Thus, this review, based on studies involving PI3K isoforms, highlight how the different PI3Ks isoforms could regulate DC functions such as antigen processing and presentation including PRR responses.

Abstract
AIM To evaluate the effectiveness and safety of the use of rebamipide as part of the triple eradication therapy (ET) scheme of Helicobacter pylori infection. MATERIALS AND METHODS A prospective, randomized comparative study included 94 patients with uncomplicated H. pylori-associated stomach / duodenal ulcer. In the process of randomization, patients are divided into three groups depending on the intended therapy. The first group (n=36) received a classical triple scheme of the first-line ET (omeprazole 20 mg twice a day, amoxicillin 1000 mg twice a day, clarithromycin 500 mg twice a day) for 10 days. Patients of the second group (n=33) were assigned a classical triple scheme of ET with the inclusion of rebamipide (omeprazole 20 mg twice a day, amoxicillin 1000 mg twice a day, clarithromycin 500 mg twice a day, rebamipide 100 mg 3 times a day day) for 10 days. Patients of the third group (n=25) were assigned a classical triple scheme of ET with the inclusion of rebamipide (omeprazole 20 mg twice a day, amoxicillin 1000 mg twice a day, clarithromycin 500 mg twice a day, rebamipide 100 mg 3 times a day) in for 10 days, with the prolongation of the administration of rebamipide for the next 20 days. The effectiveness of ET was determined by the respiratory test after 6 weeks after the end of treatment. Adverse events were recorded by patients in specially developed diaries. All patients with gastric ulcer at the 6th week underwent a histological examination of the biopsy specimens of the antrum and the body of the stomach, assessing the inflammatory activity of the process on a point system in accordance with the updated Sydney system. RESULTS Efficiency of H. pylori eradication in the first group was 77.7% (ITT), 82.3% (PP), in the second group - 81.8% (ITT), 84.4% (PP), and in the third group - 84% (ITT), 87.5% (PP). The use of rebamipide in the triple ET regimen was associated with an increase in H. pylori eradication efficiency, both with simultaneous use with the scheme [odds ratio (OR) 1.16; 95% confidence interval (CI) 0.32-4.24], and with subsequent prolonged admission (OR 1.5, 95% CI 0.34-6.7). A somewhat more pronounced dynamics of the epithelization of erosive and ulcerative changes in the mucous membrane of the stomach and duodenum to the 21st and 28th days in the third group of patients was noted. The incidence of adverse events between the groups was comparable: 22.2% in the first group, 24.2% in the second group and 20% in the third group. In the pathomorphological evaluation of biopsy specimens of patients with gastric ulcer at the 6th week after the treatment, significant differences were revealed between the first and third groups in terms of the inflammatory activity in the antrum stomach (2±0.63 vs. 1.4±0.52; p=0,0399). CONCLUSION The inclusion of rebamipide in the classical triple scheme of H. pylori ET increases the effectiveness of treatment and does not affect the safety profile. In the post-eradication period, it is advisable to continue the use of rebamipide to potentiate the repair of the gastric mucosa and regress the inflammatory processes.

Abstract
Berberine (BBR), an alkaloid isolated from Rhizoma Coptidis, Cortex Phellode, and Berberis, has been widely used in the treatment of ulcerative colitis (UC). However, the mechanism of BBR on UC is unknown. In this study, we investigated the activities of T regulatory cell (Treg) and T helper 17 cell (Th17) in a dextran sulfate sodium (DSS)-induced UC mouse model after BBR administration. We also investigated the changes of gut microbiota composition using 16S rRNA analysis. We also examined whether BBR could regulate the Treg/Th17 balance by modifying gut microbiota. The mechanism was further confirmed by depleting gut microbiota through a combination of antibiotic treatment and fecal transplantations. Results showed that BBR treatment could improve the Treg/Th17 balance in the DSS-induced UC model. BBR also reduced diversity of the gut microbiota and interfered with the relative abundance of Desulfovibrio, Eubacterium, and Bacteroides. Moreover, BBR treatment did not influence the Treg/Th17 balance after the depletion of gut microbiota. Our results also revealed that fecal transplantation from BBR-treated mice could relieve UC and regulate the Treg/Th17 balance. In conclusion, our study provides evidence that BBR prevents UC by modifying gut microbiota and regulating the balance of Treg/Th17.

Magnolol Alleviates Inflammatory Responses and Lipid Accumulation by AMP-Activated Protein Kinase-Dependent Peroxisome Proliferator-Activated Receptor α Activation. Front Immunol 2018; 9:147.

Abstract
Magnolol (MG) is a kind of lignin isolated from Magnolia officinalis, which serves several different biological functions, such as antifungal, anticancer, antioxidant, and hepatoprotective functions. This study aimed to evaluate the protective effect of MG against oleic acid (OA)-induced hepatic steatosis and inflammatory damage in HepG2 cells and in a tyloxapol (Ty)-induced hyperlipidemia mouse model. Our findings indicated that MG can effectively inhibit OA-stimulated tumor necrosis factor α (TNF-α) secretion, reactive oxygen species generation, and triglyceride (TG) accumulation. Further study manifested that MG significantly suppressed OA-activated mitogen-activated protein kinase (MAPK) and nuclear factor-kappa B (NF-κB) signaling pathways and that these inflammatory responses can be negated by pretreatment with inhibitors of extracellular regulated protein kinase and c-Jun N-terminal kinase (U0126 and SP600125, respectively). In addition, MG dramatically upregulated peroxisome proliferator-activated receptor α (PPARα) translocation and reduced sterol regulatory element-binding protein 1c (SREBP-1c) protein synthesis and excretion, both of which are dependent upon the phosphorylation of adenosine monophosphate (AMP)-activated protein kinase (AMPK), acetyl-CoA carboxylase, and AKT kinase (AKT). However, MG suspended the activation of PPARα expression and was thus blocked by pretreatment with LY294002 and compound c (specific inhibitors of AKT and AMPK). Furthermore, MG clearly alleviated serum TG and total cholesterol release; upregulated AKT, AMPK, and PPARα expression; suppressed SREBP-1c generation; and alleviated hepatic steatosis and dyslipidemia in Ty-induced hyperlipidemia mice. Taken together, these results suggest that MG exerts protective effects against steatosis, hyperlipidemia, and the underlying mechanism, which may be closely associated with AKT/AMPK/PPARα activation and MAPK/NF-κB/SREBP-1c inhibition.

Abstract
Stress refers to a dynamic process in which the homeostasis of an organism is challenged, the outcome depending on the type, severity, and duration of stressors involved, the stress responses triggered, and the stress resilience of the organism. Importantly, the relationship between stress and the immune system is bidirectional, as not only stressors have an impact on immune function, but alterations in immune function themselves can elicit stress responses. Such bidirectional interactions have been prominently identified to occur in the gastrointestinal tract in which there is a close cross-talk between the gut microbiota and the local immune system, governed by the permeability of the intestinal mucosa. External stressors disturb the homeostasis between microbiota and gut, these disturbances being signaled to the brain via multiple communication pathways constituting the gut-brain axis, ultimately eliciting stress responses and perturbations of brain function. In view of these relationships, the present article sets out to highlight some of the interactions between peripheral immune activation, especially in the visceral system, and brain function, behavior, and stress coping. These issues are exemplified by the way through which the intestinal microbiota as well as microbe-associated molecular patterns including lipopolysaccharide communicate with the immune system and brain, and the mechanisms whereby overt inflammation in the GI tract impacts on emotional-affective behavior, pain sensitivity, and stress coping. The interactions between the peripheral immune system and the brain take place along the gut-brain axis, the major communication pathways of which comprise microbial metabolites, gut hormones, immune mediators, and sensory neurons. Through these signaling systems, several transmitter and neuropeptide systems within the brain are altered under conditions of peripheral immune stress, enabling adaptive processes related to stress coping and resilience to take place. These aspects of the impact of immune stress on molecular and behavioral processes in the brain have a bearing on several disturbances of mental health and highlight novel opportunities of therapeutic intervention.

Abstract
AIM To estimate annual direct and indirect costs for patients diagnosed with irritable bowel syndrome (IBS) and subtypes.
METHODS Patients completed a standardized questionnaire concerning usage of healthcare resources, travel costs, meals, and productivity loss of patients when seeking treatment for IBS. Total annual costs per patient were calculated as the sum of direct (including medical and nonmedical) and indirect costs. Total annual costs per patient among various IBS subtypes were compared. Analysis of variance and bootstrapped independent sample t-tests were performed to determine differences between groups after controlling for IBS subtypes.
RESULTS A total of 105 IBS patients (64.80% female), mean age of 57.12 years ± 10.31 years), mean disease duration of 4.31 years ± 5.40 years, were included. Total annual costs per patient were estimated as CNY18262.84 (USD2933.08). Inpatient and outpatient healthcare use were major cost drivers, accounting for 46.41%and 23.36% of total annual costs, respectively. Productivity loss accounted for 25.32% of total annual costs. The proportions of direct and indirect costs were similar to published studies in other countries. Nationally, the total costs of managing IBS would amount to CNY123.83 billion (USD1.99 billion). Among the IBS subtypes, total annual costs per patient of IBS-M was highest at CNY18891.18 (USD3034). Furthermore, there was significant difference in productivity loss among IBS subtypes (P = 0.031).
CONCLUSION IBS imposes a huge economic burden on patients and healthcare systems, which could account for 3.3% of the total healthcare budget for the entire Chinese nation. More than two-thirds of total annual costs of IBS consist of inpatient and outpatient healthcare use. Among the subtypes, IBS-M patients appear to have the greatest economic burden but require further confirmation.

Abstract
Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous group of autosomal recessive genetic diseases with a major clinical manifestation of severe intrahepatic cholestasis and an incidence rate of 1/10000 to 1/5000. PFIC is usually first diagnosed in infancy or childhood and eventually develops into liver failure and death. Based on clinical manifestations, laboratory tests, and genetic defects in liver tissue, PFIC is roughly divided into three types: PFIC-1, PFIC-2 and PFIC-3. Studies have demonstrated that all three types of PFIC are associated with the mutations of bile transport system genes in the liver. Promoting transporter expression has important clinical significance for the treatment of PFIC. In this paper, we summarize the etiology and treatment status of PFIC and discuss the treatment of PFIC by promoting the expression of transporters.

Abstract
Hepatocellular carcinoma (HCC) is a major health problem worldwide, representing one of the leading causes of death. Chronic hepatitis B virus (HBV) infection (CHB) is the most important etiologic factor of this tumor, accounting for the development of more than 50% of the cases in the world. Primary prevention of HCC is possible by hepatitis B vaccination conferring protection from HBV infection. However, according to the World Health Organization Hepatitis B Fact sheet N° 204 (update of July 2014) globally there exists a large pool of > 240 million people chronically infected with HBV who are at risk for development of HCC. These individuals represent a target population for secondary prevention both of cirrhosis and of HCC. Since ongoing HBV replication in CHB is linked with the progression of the underlying liver disease to cirrhosis as well as with the development of HCC, effective antiviral treatment in CHB has also been evaluated in terms of secondary prevention of HCC. Currently, most patients with active CHB are subjected to long term treatment with the first line nucleos(t)ide analogues entecavir and tenofovir. These compounds are of high antiviral potency and have a high barrier to HBV resistance compared to lamivudine, adefovir dipivoxil and even telbivudine. Many studies have shown that patients under antiviral treatment, especially those in virological remission, develop less frequently HCC compared to the untreated ones. However, the risk for development of HCC cannot be eliminated. Therefore, surveillance for the development of HCC of patients with chronic hepatitis B must be lifelong or until a time in the future when new treatments will be able to completely eradicate HBV from the liver particularly in the early stages of CHB infection. In this context, the aim of this review is to outline the magnitude of the risk for development of HCC among patients with CHB, in the various phases of the infection and in relation to virus, host and environmental factors as evaluated in the world literature. Moreover, the benefits of antiviral treatment of CHB with nucleos/tide analogs, which have changed the natural history of the disease and have reduced but not eliminated the risk of HCC are also reviewed.

Abstract
A cohort of family members with various chronic diseases including Crohn's disease, asthma, complex regional pain syndrome, hypothyroidism, type 1 diabetes mellitus, and lymphangiomatosis and/or evidence of infection by Mycobacterium avium subsp. paratuberculosis (MAP) are described in this series of case reports. MAP was cultured from the blood of three members affected by the first five diseases and there was accompanying elevated anti-MAP IgG in two members. The patient affected by the sixth disease has a markedly elevated anti-MAP titer. The two patients affected by the first four diseases have been treated with a combination of anti-MAP antibiotics and ultraviolet blood irradiation therapy with resolution of the disease symptomatology and inability to culture MAP in post treatment blood samples. These case reports of patients with MAP infections provide supportive evidence of a pathogenic role of MAP in humans.

Abstract
The purpose of this article review is to update what is known about the role of diet on non-alcoholic fatty liver disease (NAFLD). NAFLD is the most common cause of chronic liver disease in the developed world and is considered to be a spectrum, ranging from fatty infiltration of the liver alone (steatosis), which may lead to fatty infiltration with inflammation known as non alcoholic steatohepatitis While the majority of individuals with risk factors like obesity and insulin resistance have steatosis, only few people may develop steatohepatitis. Current treatment relies on weight loss and exercise, although various insulin-sensitizing medications appear promising. Weight loss alone by dietary changes has been shown to lead to histological improvement in fatty liver making nutrition therapy to become a cornerstone of treatment for NAFLD. Supplementation of vitamin E, C and omega 3 fatty acids are under consideration with some conflicting data. Moreover, research has been showed that saturated fat, trans-fatty acid, carbohydrate, and simple sugars (fructose and sucrose) may play significant role in the intrahepatic fat accumulation. However, true associations with specific nutrients yet to be clarified.

Abstract
AIM: To explore the feasibility of using in vivo cerebral microdialysis and high performance liquid chromatography (HPLC) to determine the contents of glutamate (Glu), glycine (Gly), γ-aminobutyric acid (γ-GABA) and taurine (Tau), and to observe the protein expression of γ-aminobutyric acid receptor A (GABAAα1) in irritable bowel syndrome with diarrhea (IBS-D) and irritable bowel syndrome with constipation (IBS-C) to investigate the preliminary pathogenesis of these two subtypes.
METHODS: Using in vitro relative recovery and in vivo relative loss ratio as monitoring indicators, the feasibility of using cerebral microdialysis and HPLC to determine the contents of Glu, Gly, Tau and γ-GABA was first explored. IBS-C was induced by cold water administration and IBS-D by folium sennae combined with restraint. Cerebral microdialysis and HPLC were then used to determine the contents of Glu, Gly, Tau and γ-GABA in the rat brain. Western blot was used to detect the expression of GABAAα1 protein in brain tissue.
RESULTS: In vivo cerebral microdialysis and HPLC were feasible for determining the contents of Glu and γ-GABA; the in vitro relative recovery rates were 21.6% and 24.5%, respectively; in vivo relative loss rates were 41.8% and 32.5%. Compared with rats in the normal group, the ratio of Glu/γ-GABA in the IBS-C and IBS-D groups significantly increased (P < 0.05). GABAAα1 protein expression in both IBS-C and IBS-D groups were significantly higher than that in the normal group (P < 0.05). In addition, GABAAα1 protein expression in the IBS-D group was significantly higher than that in the IBS-C group (P < 0.05).
CONCLUSION: The pathogenesis of IBS-C and IBS-D may be related with Glu/GABA ratio and GABAAα1 in the brain.

Abstract
Over the last two decades, the rise in the prevalence rates of overweight and obesity explains the emergence of nonalcoholic fatty liver disease (NAFLD) as the leading cause of chronic liver disease worldwide. As described in adults, children and adolescents with fatty liver display insulin resistance, glucose intolerance, and dyslipidemia. Thus NAFLD has emerged as the hepatic component of the metabolic syndrome (MetS) and a strong cardiovascular risk factor even at a very early age. Several studies, including pediatric populations, have reported independent associations between NAFLD and markers of subclinical atherosclerosis including impaired flow-mediated vasodilation, increased carotid artery intima-media thickness, and arterial stiffness, after adjusting for cardiovascular risk factors and MetS. Also, it has been shown that NAFLD is associated with cardiac alterations, including abnormal left ventricular structure and impaired diastolic function. The duration of these subclinical abnormalities may be important, because treatment to reverse the process is most likely to be effective earlier in the disease. In the present review, we examine the current evidence on the association between NAFLD and atherosclerosis as well as between NAFLD and cardiac dysfunction in the pediatric population, and discuss briefly the possible biological mechanisms linking NAFLD and cardiovascular changes. We also address the approach to treatment for this increasingly prevalent disease, which is likely to have an important future global impact on the burden of ill health, to prevent not only end-stage liver disease but also cardiovascular disease.

Abstract
Alcohol is one of the main factors of liver damage. The evaluation of the degree of liver fibrosis is of great value for therapeutic decision making in patients with alcoholic liver disease (ALD). Staging of liver fibrosis is essential to define prognosis and management of the disease. Liver biopsy is a gold standard as it has high sensitivity and specificity in fibrosis diagnostics. Taking into account the limitations of liver biopsy, there is an exigency to introduce non-invasive serum markers for fibrosis that would be able to replace liver biopsy. Ideal serum markers should be specific for the liver, easy to perform and independent to inflammation and fibrosis in other organs. Serum markers of hepatic fibrosis are divided into direct and indirect. Indirect markers reflect alterations in hepatic function, direct markers reflect extracellular matrix turnover. These markers should correlate with dynamic changes in fibrogenesis and fibrosis resolution. The assessment of the degree of liver fibrosis in alcoholic liver disease has diagnostic and prognostic implications, therefore noninvasive assessment of fibrosis remains important. There are only a few studies evaluating the diagnostic and prognostic values of noninvasive biomarkers of fibrosis in patients with ALD. Several noninvasive laboratory tests have been used to assess liver fibrosis in patients with alcoholic liver disease, including the hyaluronic acid, FibroTest, FibrometerA, Hepascore, Forns and APRI indexes, FIB4, an algorithm combining Prothrombin index (PI), α-2 macroglobulin and hyaluronic acid. Among these tests, Fibrotest, FibrometerA and Hepascore demonstrated excellent diagnostic accuracy in identifying advanced fibrosis and cirrhosis, and additionally, Fibrotest was independently associated with survival. Therefore, the use of biomarkers may reduce the need for liver biopsy and permit an earlier treatment of alcoholic patients.

Abstract
Nonalcoholic fatty liver disease (NAFLD) refers to the accumulation of fat (mainly triglycerides) within hepatocytes. Approximately 20%-30% of adults in the general population in developed countries have NAFLD; this trend is increasing because of the pandemicity of obesity and diabetes, and is becoming a serious public health burden. Twenty percent of individuals with NAFLD develop chronic hepatic inflammation [nonalcoholic steatohepatitis (NASH)], which can be associated with the development of cirrhosis, portal hypertension, and hepatocellular carcinoma in a minority of patients. And thus, the detection and diagnosis of NAFLD is important for general practitioners. Liver biopsy is the gold standard for diagnosing NAFLD and confirming the presence of NASH. However, the invasiveness of this procedure limits its application to screening the general population or patients with contraindications for liver biopsy. The development of noninvasive diagnostic methods for NAFLD is of paramount importance. This review focuses on the updates of noninvasive diagnosis of NAFLD. Besides, we review clinical evidence supporting a strong association between NAFLD and the risk of cardiovascular disease because of the cross link between these two disorders.

[PMID: 24944497 PMCID: PMC4051946 DOI: 10.3748/wjg.v20.i22.7019] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2013] [Revised: 01/25/2014] [Accepted: 03/06/2014] [Indexed: 02/06/2023] Open
Abstract
AIM: To investigate the correlation between the appearance of skin lesions and concentration of interleukin (IL)-17A, IL-23 and interferon-γ (IFN-γ) in Crohn’s disease (CD) patients during anti-tumor necrosis factor-α (TNF-α) therapy
METHODS: A prospective study included 30 adult patients with CD of Caucasian origin (19 men and 11 women; mean age ± SD 32.0 ± 8.6 years) during biological therapy with anti-TNF-α antibodies from January 2012 to March 2013. Eighteen patients were treated with infliximab, seven with adalimumab and five with certolizumab. Inclusion criteria were exacerbation of the underlying disease, Crohn’s Disease Activity Index over 300 and the ineffectiveness of previously used non-biological therapies. Patients with a history of psoriasis, atopic dermatitis and other autoimmune skin lesions were excluded from the study. The control group consisted of 12 healthy subjects. A diagnostic survey was carried out, blood tests and careful skin examination were performed, and the serum levels of IL-17, IL-23 and IFN-γ were measured using an enzyme-linked immunosorbent assays technique. Dermatoses that have developed in the course of biological therapy in patients who had no pre-existing skin lesions of similar character were qualified as skin lesions induced by anti-TNF-α therapy.
RESULTS: Skin manifestations occurred in 18 of CD patients during the anti-TNF-α therapy (60%), in the average time of 10.16 ± 3.42 mo following the beginning of the 52-wk treatment cycle. Skin lesions observed in CD patients during biological therapy included psoriasiform lesions (44.4%), and eczema forms lesions (22.2%). In CD patients with drug induced skin lesions significantly higher levels of hemoglobin (13.3 ± 1.5 g/dL vs 10.8 ± 1.9 g/dL, P = 0.018) and hematocrit (39.9% ± 4.5% vs 34.3% ± 5.4%, P = 0.01), as well as a significantly lower level of platelets (268 ± 62 × 103/μL vs 408 ± 239 × 103/μL, P = 0.046) was observed compared with CD patients without skin manifestations. The concentrations of IL-17A and IL-23 in CD patients with skin lesions developed under anti-TNF-α therapy were significantly higher compared to those in patients without lesions (IL-17A: 39.01 ± 7.03 pg/mL vs 25.71 ± 4.90 pg/mL, P = 0.00004; IL-23: 408.78 ± 94.13 pg/mL vs 312.15 ± 76.24 pg/mL, P = 0.00556).
CONCLUSION: Skin lesions in CD patients during biological therapy may result from significantly increased concentrations of IL-17A and IL-23, which are strongly associated with TNF-α/Th1 immune pathways.

Abstract
Gastric cancer (GC), which is mainly induced by Helicobacter pylori (H. pylori) infection, is one of the leading causes of cancer-related death in the developing world. Active inflammation initiated by H. pylori infection and maintained by inherent immune disorders promotes carcinogenesis and postoperative recurrence. However, the presence with H. pylori in tumors has been linked to a better prognosis, possibly due to the induction of antitumor immunity. Tumor infiltrations of tumor-associated macrophages, myeloid-derived suppressor cells, neutrophils, Foxp3+ regulatory T cells are correlated with poor prognosis. Tumor infiltrating CD8+ cytotoxic T lymphocytes, dendritic cells, and CD45RO T cells are generally associated with good prognosis of GC, although some subsets of these immune cells have inverse prognosis prediction values. High ratios of Foxp3+/CD4+ and Foxp3+/CD8+ in tumors are associated with a poor prognosis; whereas high Th1/Th2 ratio in tumors predicts a good prognosis. High levels of interleukin (IL)-6, IL-10, IL-32, and chemokine C-C motif ligands (CCL)7 and CCL21 in circulation, high expression of CXC chemokine receptor 4, chemokine C-C motif receptor (CCR)3, CCR4, CCR5, CCR7, hypoxia-inducible factor-1α, signal transducer activator of transcription-3, cyclooxygenase-2, and orphan nuclear receptor 4A2 in tumors are associated with an unfavorable prognosis. Increased serum levels of matrix metalloproteinases (MMP)-3, MMP-7, and MMP-11 and increased levels of MMP-9, MMP-12, and MMP-21 in tumors are consistently associated with poor survival of GC. Further emphasis should be put on the integration of these biomarkers and validation in large cohorts for personalized prediction of GC postoperative prognosis.

Abstract
AIM: To observe the effect of Qingfei Chengqi granules on immune response in early severe acute pancreatitis (SAP) patients.
METHODS: Sixty-eight patients with early SAP were randomly assigned to either an observation group or a control group. The observation group received Western medicine treatment plus Qingfei Chengqi granules, while the control group received Western medicine therapy plus placebo. The expression rate of human leukocyte antigen DR [HLA-DR (%)], helper T lymphocytes 1/2 (Th1/Th2) and regulatory T lymphocytes (Tregs) in peripheral blood were determined on days 1, 3, 7 and 14.
RESULTS: Nine (13.24%) patients die within 28 days, including three (9.09%) in the observation group and six (17.14%) in the control group. Compared with the control group, HLA-DR (%) on days 7 and 14 (86.77% ± 17.39% vs 65.46% ± 28.72%, 85.43% ± 20.36% vs 73.32% ± 29.03%, P < 0.05 for both) and Tregs on days 1 and 3 (9.37% ± 5.61% vs 5.65% ± 3.75%, 9.10% ± 6.86% vs 7.09% ± 4.80%, P < 0.05 for both) were significantly increased, and Th1/Th2 on days 7 and 14 (3.58 ± 3.74 vs 4.62 ± 2.69, 3.54 ± 2.65 vs 5.64 ± 2.34, P < 0.05 for both) were significantly decreased in the observation group. Compared with pretreatment values in the observation group, HLA-DR (%) on days 7 and 14 (86.77% ± 17.39% vs 67.71% ± 28.63%, 85.43% ± 20.36% vs 67.71% ± 28.63%, P < 0.05 for both) and Tregs on days 1 and 3 (9.37% ± 5.61% vs 6.11% ± 4.08%, 9.10% ± 6.86% vs 6.11% ± 4.08%, P < 0.05) were significantly increased, and Th1/Th2 on days 7 and 14 (3.58 ± 3.74 vs 5.96 ± 6.12, 3.54 ± 2.65 vs 5.96 ± 6.12, P < 0.05 for both) were significantly decreased after treatment. Compared with pretreatment values in the control group, HLA-DR (%) on day 14 (73.32% ± 29.03% vs 61.71% ± 28.77%, P < 0.05) were significantly increased.
CONCLUSION: Qingfei Chengqi granules may enhance antigen presentation and immune response to reduce immune suppression in early SAP possibly by inducing high expression of Treg cells to promote the transition of Th1 to Th2 cells, thereby reducing inflammation damage and fatality rate.

Abstract
Hepatopulmonary syndrome (HPS) is characterized as a triad: liver disease, intrapulmonary vascular dilatation and arterial hypoxemia. HPS is reported to be present in 4% to 32% of adult patients with end-stage liver disease and in 9%-20% of children. The pathogenesis of HPS has not been clearly identified. Portal hypertension causes impairment in the perfusion of the bowel and increases the enteral translocation of Gram (-) bacteria and endotoxins. This stimulates the release of vasoactive mediators, such as tumor necrosis factor-alpha, heme oxygenase-derived carbon monoxide and nitric oxide. Genetic alterations have not been associated with this syndrome yet; however, cytokines and chemokines have been suggested to play a role. Recently, it was reported that cumulated monocytes lead to the activation of vascular endothelial growth factor-dependent signaling pathways and pulmonary angiogenesis, which plays an important role in HPS pathogenesis. At present, the most effective and only radical treatment is a liver transplant (LT). Cirrhotic patients who are on the waiting list for an LT have a shorter survival period if they develop HPS. Therefore, it is suggested that all cirrhotic cases should be followed closely for HPS and they should have priority in the waiting list.

Abstract
Helicobacter pylori (H. pylori) is a highly prevalent, serious and chronic infection that has been associated causally with a diverse spectrum of extragastric disorders including iron deficiency anemia, chronic idiopathic thrombocytopenic purpura, growth retardation, and diabetes mellitus. The inverse relation of H. pylori prevalence and the increase in allergies, as reported from epidemiological studies, has stimulated research for elucidating potential underlying pathophysiological mechanisms. Although H. pylori is most frequently acquired during childhood in both developed and developing countries, clinicians are less familiar with the pediatric literature in the field. A better understanding of the H. pylori disease spectrum in childhood should lead to clearer recommendations about testing for and treating H. pylori infection in children who are more likely to develop clinical sequelae. A further clinical challenge is whether the progressive decrease of H. pylori in the last decades, abetted by modern clinical practices, may have other health consequences.

Abstract
AIM: To investigate whether autologous dendritic cell (DC)-cytokine-induced killer (CIK) cell therapy is able to improve the therapeutic efficacy of chemotherapy in colon cancer.
METHODS: We conducted a systematic review of published papers from the sources of MEDLINE, the Cochrane Central Register of Controlled Trials, EMBASE, the Wanfang Database, the China Science and Technology Periodical Database and China Journal Net. Published data were extracted independently by two authors using predefined database templates. The quality of the data from individual papers was also assessed. The effects of chemotherapy were compared with those of chemotherapy in combination with DC-CIK immunotherapy. The pooled analysis was performed using the data from random or fixed-effect models.
RESULTS: Seven trials matched our inclusion criteria (n = 533). The overall analysis showed significant survival benefit [one-year overall survival (OS), P < 0.0001; two-year OS, P = 0.009; three-year OS, P = 0.002] in favor of DC-CIK immunotherapy combined with chemotherapy. Disease-free survival (DFS) rate was improved after the combination of DC-CIK immunotherapy and chemotherapy (one-year DFS, P < 0.0001; two-year DFS, P = 0.002; three-year DFS, P = 0.02). An improved overall response rate (P = 0.009) was also observed in patients who received DC-CIK therapy. Furthermore, the analysis of T-lymphocyte subsets in peripheral blood indicated that the number of CD4+ T cells significantly increased in the DC-CIK plus chemotherapy group (P < 0.05).
CONCLUSION: The combination of DC-CIK immunotherapy and chemotherapy was superior in prolonging the survival time and enhancing immunological responses.

Abstract
Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide, with the majority of cases associated with persistent infection from hepatitis B virus (HBV) or hepatitis C virus (HCV). Natural history studies have identified risk factors associated with HCC development among chronic HBV and HCV infection. High-risk infected individuals can now be identified by the usage of risk predictive scores. Vaccination plays a central role in the prevention of HBV-related HCC. Treatment of chronic HBV infection, especially by nucleoside analogue therapy, could also reduce the risk of HBV-related HCC. Concerning HCV infection, besides the advocation of universal precautions to reduce the rate of infection, pegylated interferon and ribavirin could also reduce the risk of HCV-related HCC among those achieving a sustained virologic response. Recently there has been mounting evidence on the role of chemopreventive agents in reducing HBV- and HCV-related HCC. The continued advances in the understanding of the molecular pathogenesis of HCC would hold promise in preventing this highly lethal cancer.

Abstract
AIM: To detect the expression of miR-320 in colorectal cancer to reveal its relationship with clinical and pathological characteristics of colorectal cancer, and to investigate the effect of miR-320 overexpression on chemosensitivity of colorectal cancer cell lines.
METHODS: The expression of miR-34a was detected by real-time PCR in CRC tissues and tumor-adjacent non-tumorous tissues. HCT-116 and ClonA1 cell lines were transfected with either a LV-miR-320 or a negative control (NC). C-Jun N-terminal kinase (JNK) expression was measured by Western blot after up-regulation of miR-320. The chemosensitivity of cell lines was tested by MTT assay.
RESULTS: MiR-320 expression was significantly down-regulated in CRC cancer tissues compared with tumor-adjacent tissues (P = 0.012). The expression of miR-320 was correlated with degree of differentiation, local invasion and TNM stage (P = 0.045, 0.012, 0.04). Overexpression of miR-320 significantly suppressed the expression of JNK, and the IC50 values for the LV-miR-320 group were significantly lower than those for the negative control group (11.34 vs 24.73, 12.56 vs 25.34, P = 0.023, 0.018).
CONCLUSION: MiR-320 is frequently down-regulated in CRC, which can repress the expression of JNK and modulate chemosensitivity of colorectal cancer cell lines. MiR-320 may play an important role in carcinogenesis and therapy of colorectal cancer.

Abstract
Helicobacter pylori (H. pylori) is closely associated with many gastrointestinal diseases, including peptic ulcers, chronic gastritis, gastric cancer and gastric mucosa-associated lymphoid tumors. In recent year, traditional triple therapy for H. pylori eradication has become less effective than the past, which is related to the resistance of bacteria. The addition of probiotics into the regimen has been proved to be able to significantly enhance the eradication rate and reduce side effects. Probiotics increase the eradication of H. pylori by recovering the damage of the chemical barrier, biological barrier, mechanical barrier and immune barrier.

Abstract
The use of anti-tumor necrosis factor-α therapy for inflammatory bowel disease represents the most important advance in the care of these patients since the publication of the National Co-operative Crohn's disease study thirty years ago. The recommendations of numerous consensus groups worldwide are now supported by a wealth of clinical trials and several meta-analyses. In general, it is suggested that tumor necrosis factor-α blockers (TNFBs) are indicated (1) for persons with moderately-severe Crohn's disease or ulcerative colitis (UC) who have failed two or more causes of glucocorticosteroids and an acceptably long cause (8 wk to 12 wk) of an immune modulator such as azathioprine or methotrexate; (2) non-responsive perianal disease; and (3) severe UC not responding to a 3-d to 5-d course of steroids. Once TNFBs have been introduced and the patient is responsive, therapy given by the IV and SC rate must be continued. It remains open to definitive evidence if concomitant immune modulators are required with TNFB maintenance therapy, and when or if TNFB may be weaned and discontinued. The supportive evidence from a single study on the role of early versus later introduction of TNFB in the course of a patient's illness needs to be confirmed. The risk/benefit profile of TNFB appears to be acceptable as long as the patient is immunized and tested for tuberculosis and viral hepatitis before the initiation of TNFB, and as long as the long-term adverse effects on the development of lymphoma and other tumors do not prone to be problematic. Because the rates of benefits to TNFB are modest from a population perspective and the cost of therapy is very high, the ultimate application of use of TNFBs will likely be established by cost/benefit studies.

Abstract
A 46-year-old female patient with terminal ileum Crohn’s disease and ankylosing spondylitis presented with recurrent angioedema and urticaria. Investigations ruled out hereditary angioedema, and environmental or food allergen triggers. She was diagnosed with chronic idiopathic urticaria with angioedema, and was treated with a trial of intravenous immunoglobulin immunotherapy, danazol, prednisone and hydroxyzine. Due to ongoing bowel and arthritic complaints, she was started on infliximab infusions and within 2 treatments, she had complete resolution of the angioedema and urticaria, as well as of the bowel and arthritic symptoms. Unfortunately she developed allergic reactions to the infliximab and was switched to another anti-tumor necrosis factor (TNF)-α agent, adalimumab. Since then, she has had no further angioedema or urticaria, and her Crohn’s disease has been quiescent. This is the first known case report of chronic idiopathic urticaria with angioedema coexistent with Crohn’s disease that was successfully treated with anti-TNF-α agents.
