Hepatocellular carcinoma (HCC) recurrence was previously characterized into four types, and patients with progression/hyper-progression recurrence (type III-IV) have an extremely poor prognosis. However, the immune background of resectable HCC, particularly in patients who experience recurrence, remains underexplored. Therefore, this study aimed to describe the immune landscape of resectable HCC, especially postoperative type III-IV recurrent HCC, and explore potential immune-targeted anti-relapse strategies for treated populations.

The differences in gene expression in patients with recurrent HCC (type I-II (solitary or multi-intrahepatic oligo recurrence) vs. type III-IV) were investigated using bulk sequencing. Multiple immune infiltration methods (single-sample gene set enrichment analysis (GSEA), Microenvironment Cell Populations-counter and ESTIMATE) were used, and patients were divided into four groups to identify four distinct immune subtypes: immune-enrichment/matrix-poor (IE1), immune-enrichment/matrix-rich (IE2), immune intermediate/matrix-rich (ITM) and immune desert/matrix-poor (ID). Co-expression and protein interaction analyses were used to identify characteristic genes in ITM closely associated with type III-IV recurrence, which was matched with drug targets for Huaier granules (HG) and lenvatinib. Virtual docking was used to identify potential therapeutic targets, and the results were verified using single-nuclei RNA sequencing and histological analysis.

ITM was closely related to type III-IV recurrence and exhibited immunotherapy potential. The potential efficacy of inhibiting CCNA2, VEGFA, CXCL8, PLK2, TIMP1, ITGB2, ALDOA, ANXA5 and CSK in ITM reversal was determined. Molecular docking demonstrated that the proteins of these genes could bind to HG or lenvatinib. The immunohistochemical findings demonstrated differential VEGFA (p < .01) and PLK2 (p < .001) expression in ITM type and ID in type III-IV recurrent HCC.

Three primary immunotypes of resectable HCC (IE2, ITM and ID) were identified, and HG and lenvatinib could potentially overcome immune checkpoint blockade (ICB) resistance in ITM patients with HCC, particularly those classified as type III-IV.

Trametes robiniophila Murr. (Huaier) is a traditional medicinal fungus known for its pharmacological properties, including heat-clearing, detoxifying, anti-inflammatory, and antitumor effects. Our previous research has demonstrated its antiviral activity, but the exact therapeutic mechanisms remain unclear. This study aims to explore the mechanisms of 50 % methanol extract of Huaier (HME) in treating influenza using 16S rRNA high-throughput sequencing and metabolomics techniques. The results showed that the HME significantly reduced the lung index and viral load in the lungs of influenza-infected mice, alleviated pathological damage in lung tissues, and downregulated the expression levels of inflammatory cytokines Interleukin-6 (IL-6), Tumor Necrosis Factor-α (TNF-α) and Interferon-γ (IFN-γ) in lung tissues. Furthermore, the HME enhanced the diversity of gut microbiota in infected mice, significantly increasing the relative abundance of beneficial bacteria, such as Alistipes and Alloprevotella. Through non-targeted metabolomic analysis of mouse feces, 45 potential biomarkers were identified. Meanwhile, the low-dose of HME was able to restore the disrupted metabolic levels. Analysis of gut microbiota and biomarker pathways revealed that HME primarily affects nicotinate and nicotinamide metabolism, which may be the key mechanism for its intervention in influenza. In addition, Spearman correlation analysis showed that most biomarkers were significantly associated with pharmacodynamics and the Alloprevotella.

This study explores the anti-tumor effects of 2-dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione (DMDD), a compound derived from Averrhoa carambola L roots, on hepatocellular carcinoma (HCC) cells and a xenograft mouse model, focusing on its underlying mechanisms. Cell viability following DMDD treatment was assessed using the CCK-8 assay. Flow cytometry determined changes in cell cycle distribution and apoptosis rates, while migration and invasion capabilities were assessed using wound healing and transwell assays, respectively. Transcriptome sequencing (RNA-seq) was conducted to analyze differential gene expression and pathway enrichment. Z-VAD-FMK, a pan-caspase inhibitor, was used to confirm the apoptotic mechanism induced by DMDD. The expression levels of p53, Bax, Bcl-2, and cleaved caspase 3 were quantified via Western blot analysis. A xenograft mouse model was developed to assess the in vivo effects of DMDD on HCC. DMDD suppressed proliferation, migration, and invasion, and induced apoptosis in Huh7 and Hep3b cells. RNA-seq revealed significant enrichment of p53 and apoptosis signaling pathways among differentially expressed genes. DMDD downregulated Bcl-2 expression and upregulated p53, Bax and cleaved caspase 3. In addition, Z-VAD-FMK partially inhibited DMDD-induced apoptosis. DMDD also inhibited tumor growth in mice. DMDD effectively inhibited tumor growth in HCC cell lines and xenograft models, potentially through ROS elevation and p53-mediated activation of the intrinsic apoptotic pathway.

Hepatocellular carcinoma (HCC), originating from hepatocytes, is the most common type of primary liver cancer. HCC imposes a significant global health burden with high morbidity and mortality, making it a critical public concern. Surgical interventions, including hepatectomy and liver transplantation, are pivotal in achieving long-term survival for patients with HCC. Additionally, ablation therapy, endovascular interventional therapy, radiotherapy, and systemic anti-tumor therapies are commonly employed. However, these treatment modalities are often associated with considerable challenges, including high postoperative recurrence rates and adverse effects. Traditional Chinese medicine (TCM) and natural products have been utilized for centuries as a complementary approach in managing HCC and its complications, demonstrating favorable clinical outcomes. Various bioactive compounds derived from TCM and natural products have been identified and purified, and their mechanisms of action have been extensively investigated. This review aims to provide a comprehensive and up-to-date evaluation of the clinical efficacy of TCM, natural products and their active constituents in the treatment and management of HCC. Particular emphasis is placed on elucidating the potential molecular mechanisms and therapeutic targets of these agents, including their roles in inhibiting HCC cell proliferation, inducing apoptosis and pyroptosis, suppressing tumor invasion and metastasis, and restraining angiogenesis within HCC tissues.

Trametes robiniophila Murr (Huaier), a traditional Chinese medicine (TCM), has shown promising effects as a complementary therapy in the treatment of multiple kinds of cancers.

This study aimed to systematically evaluate whether Huaier could enhance the antitumor effects of palbociclib, a highly selective CDK4/6 inhibitor.

A breast cancer xenograft mouse model was constructed to assess the anticancer effects of Huaier and palbociclib. Transcriptomic analysis was performed to identify the differentially expressed genes and associated pathways. Flow cytometry, immunofluorescence and immunohistochemical staining were then conducted to observe the infiltration of immune cells in the tumor microenvironment (TME). The composition of the gut microbiota was explored through 16S rDNA sequencing, and a pseudosterile mouse model was established to verify the contribution of the gut microbiota to the antitumor effects of Huaier and palbociclib.

Oral administration of Huaier enhanced the antitumor effects of palbociclib in breast cancer. Transcriptomic analysis of tumor tissues revealed that the differentially expressed genes were related to immune functions. Indeed, the addition of Huaier to palbociclib therapy further increased the ratio of CD8+/CD3+ T cells and the abundance of GzmB+CD8+ T cells in the TME. Mechanistically, sequencing of 16S rDNA revealed that Huaier reshaped the gut microbiota composition in favor of Akkermansia, which positively modulated antitumor immune responses. The pseudosterile mouse model verified the necessity of the gut microbiota for the synergistic effect of Huaier on palbociclib. Furthermore, butyrate, a metabolite of Akkermansia, synergized with palbociclib to suppress tumor progression and promote the infiltration of CD8+ T cells in the TME.

Our data suggested that Huaier augmented the antitumor effects of palbociclib by increasing the abundance of Akkermansia in gut microbiota, which contributed to the enhancement of anti-tumor immunity. Consequently, combining palbociclib with Huaier may serve as a promising strategy for the treatment of breast cancer.

Hepatocellular carcinoma (HCC) is the most prevalent malignancy in China, with liver resection recognized as the primary curative intervention. However, HCC patients face an elevated risk of recurrence, thereby significantly impacting prognosis.

This study aimed to assess the impact of adjuvant programmed cell death protein-1 (PD-1) inhibitors on survival outcomes in patients with HCC who are at high risk for postoperative recurrence following curative hepatectomy.

Among the 199 study participants, 77 received adjuvant PD-1 inhibitors. Propensity score matching (PSM) was used to balance baseline differences between patients who received adjuvant PD-1 inhibitors and those who did not. Assessment of overall survival (OS) and recurrence-free survival (RFS) was conducted using Kaplan-Meier curves, while Cox regression analysis was employed to identify prognostic factors influencing survival.

After PSM, the 1-year and 2-year RFS were 87.1% and 74.2% in the PD-1 inhibitors group and 44.6% and 37.8% in non-PD-1 inhibitors group (p < 0.001). The 1-year and 2-year OS were 98.5% and 95.7% in the PD-1 inhibitors group compared with 90.7% and 77.0% in non-PD-1 inhibitors group (p = 0.004). Multivariable analyses demonstrated that the use of adjuvant PD-1 inhibitors was significantly associated with improved RFS and OS. Subgroup analysis indicated that adjuvant PD-1 inhibitors group achieved longer RFS than the non-PD-1 inhibitors group in patients without adjuvant transarterial chemoembolization (TACE).

The administration of adjuvant PD-1 inhibitors may effectively reduce the risk of tumor recurrence and improve survival in HCC patients with high risk of recurrence after curative hepatectomy.

Rutin is a valuable traditional Chinese medicine known for its anti-inflammatory and anticancer effects. It has been shown to be effective in treating various inflammation-associated diseases. Here, we investigated the influence of rutin on acute pancreatitis and tumorigenesis. Using C57BL/6J mice and Kras mutant transgenic mice, we induced pancreatitis and acinar regeneration models. Pancreatic malondialdehyde (MDA), superoxide dismutase (SOD) activity and reduced glutathione (GSH) contents were measured for oxidative stress. Histological staining and a pancreatic acinar 3D culture model were used to clarify the influence of rutin on ADM in vivo and in vitro. Western blotting was adopted to detect ADM markers amylase and CK19. We found that rutin ameliorated inflammatory injury to the pancreas in both caerulein- and arginine-induced AP. Then, we revealed that the anti-damage effect of rutin may be due to its inhibition of oxidative stress. In addition, an acinar 3D culture model showed that rutin inhibited the formation of ADM by activating AMPK in acinar cells. Finally, the activation of AMPK is believed to be a potential mechanism by which rutin exerts inhibitory effects on Kras-driven tumorigenesis. Rutin inhibited AP-induced pancreatic injury and oncogenic Kras-driven tumorigenesis by inhibiting ADM.

Liver cancer was the third cause of global cancer death, while China has the largest number of patients. And traditional Chinese medicine is an important strategy for liver cancer. There into, Huaier polysaccharides (HP), the major component of Trametes robiniophila Murr., as a preparation of Huaier granule, is recommended by clinical guidelines for Hepatocellular carcinoma (HCC). However, the anti-HCC mechanism remains unclear. Herein, we investigated whether HP could suppress HCC and revealed the underlying mechanism. Firstly, HP showed a weaker proliferation inhibitory effect on the mouse source and human HCC cells in vitro, but exhibited stronger anti-HCC effects in animals. And nude mice models confirmed that macrophages play an important role in the anti-HCC effect of HP. Then, we observed that HP reduced the polarization of M2 macrophages in tumor microenvironment and increased the secretion of pro-inflammatory factors by macrophages. Moreover, 16 s rRNA gene sequencing and non-targeted metabolomics analysis revealed that HP altered the gut microbiota and related metabolites. Eventually, antibiotic intervention eliminated the efficacy and reduced the expression of pro-inflammatory factors, confirming that the gut microbiota is a key molecule for HP efficacy. In addition, MTT and EdU assay indicated that Chenodeoxycholic acid (CDCA) were potential microbial metabolites influencing efficacy of HP. In conclusion, our data revealed that Huaier polysaccharides inhibited HCC via gut microbiota mediated M2 macrophage polarization, providing sufficient scientific support for Huaier polysaccharides clinical application and indicating the indispensable role of polysaccharides in life health.

Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the digestive tract, often accompanied by a high risk of recurrence and drug resistance. Huaier (Trametes robiniophila Murr), a traditional Chinese medicinal fungus, has demonstrated potent anticancer properties and is widely used as an adjuvant treatment for liver, breast, gastric, colon, and non-small cell lung cancers. However, its effects and molecular mechanisms in GIST remain unclear.

This study aims to explore the inhibitory effects and underlying mechanisms of Huaier on GIST through network pharmacology and experimental validation.

Initially, we utilized a publicly accessible database to identify the core targets and principal pathways associated with Huaier's therapeutic effects on gastrointestinal stromal tumors. To further evaluate its biological impact, cell viability, proliferation, migration, and invasion were assessed through CCK-8 and EdU assays, wound healing tests, and Transwell experiments. Apoptotic cell death was quantified using flow cytometry analysis. Additionally, the influence of Huaier extract on the expression levels of JAK2 and STAT3 proteins was examined via Western blotting. Finally, a subcutaneous xenograft mouse model was employed to investigate the anti-tumor efficacy of Huaier in vivo.

In this study, GAPDH, TNF, STAT3, ESR1, EGFR, IL6, CCND1, PTGS2, BCL2L1, and MAPK3 were identified as shared molecular targets, with the JAK/STAT signaling pathway recognized as the pivotal regulatory mechanism. Experimental findings demonstrated that Huaier exerted inhibitory effects on the proliferation, migration, and invasion of GIST-T1 and GIST-882 cells, exhibiting both dose- and time-dependent responses. Furthermore, Huaier was found to promote apoptosis in these cells. Western blot analysis revealed that treatment with Huaier extract significantly decreased the phosphorylation levels of JAK2 and STAT3, thereby suppressing the activation of the JAK2/STAT3 signaling cascade. In vivo experiments further substantiated these findings, showing that Huaier treatment markedly reduced tumor size and inhibited tumor progression.

Our results suggest that Huaier may inhibit the growth of GIST cells by inhibiting the JAK2/STAT3 signaling pathway, reduce cell proliferation, induce apoptosis, reduce cell migration and invasion, and show anti-tumor effects in vivo and in vitro.

Huaier granule is an important medicinal fungus extract widely used in cancer treatment. Previous retrospective studies have reported its effectiveness in breast cancer patients, but the imbalanced baseline characteristics of participants could have biased the results. Therefore, this retrospective study aimed to examine the efficacy of Huaier granule on the prognosis of breast cancer patients.

In this single-center cohort study, breast cancer patients diagnosed and treated at the Guangdong Provincial Hospital of Chinese Medicine between 2009 and 2017 were selected. The data were retrospectively analyzed and divided into two groups according to whether the patients received Huaier granules. The propensity score matching (PSM) method was used to eliminate selection bias. The disease-free survival (DFS) and overall survival (OS) for these groups were compared using the Kaplan-Meier method and the Cox regression.

This study included 214 early invasive breast cancer patients, 107 in the Huaier group and 107 in the control group. In the Kaplan-Meier analysis, the 2-year and 5-year DFS rates were significantly different in the Huaier group and control group (hazard ratio [HR], 0.495; 95% confidence interval [CI], 0.257-0.953; P = 0.023). The 2-year and 5-year OS rates were also significantly different (HR, 0.308; 95% CI, 0.148-0.644; P = 0.001). On multivariable Cox regression, Huaier granule was associated with improved DFS (HR, 0.440; 95% CI, 0.223-0.868; P = 0.018) and OS (HR, 0.236; 95% CI, 0.103-0.540; P = 0.001).

In this retrospective study, Huaier granules improved the DFS and OS of early invasive breast cancer patients, providing real-world evidence for further prospective studies on treating breast cancer with Huaier granules.

For the treatment of early hepatocellular carcinoma, we compared the efficacy and safety of radiofrequency ablation (RFA) alone and radiofrequency ablation combined with sorafenib (RFA+Sor).

A total of 164 patients with early HCC were included in the study. There were 87 patients who underwent RFA alone, and 77 patients who underwent RFA+Sor treatment. Overall survival (OS) was the primary endpoint of the study, and recurrence-free survival (RFS) and safety were the secondary endpoints.

According to the RFA group, the RFS rates were 74.7%, 29.9%, and 11.5% at 1, 2, and 3 years, whereas in the RFA+Sor group, the RFS rates were 72.7%, 19.5%, and 11.7% at 1, 2, and 3 years (P>0.05). RFA and RFA+Sor groups had median OS of 35.0 and 41.0 months, respectively (P>0.05). For the RFA and RFA+Sor groups, the median RFS was 17.0 and 16.0 months, respectively (P>0.05). Based on the univariate regression analysis, there was no statistically significant difference between the subgroups (P>0.05). Skin rashes only occurred in the RFA+Sor group, and other adverse effects were not significantly different between the two groups (P>0.05).

Treatment with RFA+Sor treatment did not result in a longer OS than treatment with only RFA, however, the adverse effects of adjuvant Sorafenib were acceptable.

Triple-negative breast cancer (TNBC) is the most intractable subgroup of breast neoplasms due to its aggressive nature. In recent years, immune checkpoint inhibitors (ICIs) have exhibited potential efficacy in TNBC treatment. However, only a limited fraction of patients benefit from ICI therapy, primarily because of the suppressive tumor immune microenvironment (TIME). Trametes robiniophila Murr (Huaier) is a traditional Chinese medicine (TCM) with potential immunoregulatory functions. However, the underlying mechanism remains unclear.

The present study aimed to investigate the therapeutic role of Huaier in the TIME of TNBC patients.

Single-cell RNA sequencing (scRNA-seq) was used to systematically analyze the influence of Huaier on the TNBC microenvironment for the first time. The mechanisms of the Huaier-induced suppression of cancer-associated fibroblasts (CAFs) were assessed via real-time quantitative polymerase chain reaction (qRT‒PCR) and western blotting. A tumor-bearing mouse model was established to verify the effects of the oral administration of Huaier on immune infiltration.

Unsupervised clustering of the transcriptional profiles suggested an increase in the number of apoptotic cancer cells in the Huaier group. Treatment with Huaier induced immunological alterations from a "cold" to a "hot" state, which was accompanied by phenotypic changes in CAFs. Mechanistic analysis revealed that Huaier considerably attenuated the formation of myofibroblastic CAFs (myoCAFs) by impairing transforming growth factor-beta (TGF-β)/SMAD signaling. In mouse xenograft models, Huaier dramatically modulated CAF differentiation, thus synergizing with the programmed cell death 1 (PD1) blockade to impede tumor progression.

Our findings demonstrate that Huaier regulates cancer immunity in TNBC by suppressing the transition of CAFs to myoCAFs and emphasize the crucial role of Huaier as an effective adjuvant agent in immunotherapy.

Trametes Robiniophila Murr, commonly known as Huaier, has been extensively documented in ethnopharmacology research in China. Huaier has a long history of clinical usage spanning over 1000 years in China. Traditional clinical application records demonstrate the wide utilization of Huaier for treating various cancers and enhancing the autoimmunity of tumor patients.

The present study provides a comprehensive review of the traditional uses, phytochemical constituents, pharmacological activities, anti-tumor mechanism, and potential applications of Huaier, thereby offering valuable insights for the further development and utilization of this natural product.

This study employed the keywords "Trametes Robiniophila Murr" and "Huaier" to retrieve relevant information on Huaier from various databases, including PubMed, Web of Science, Springer, Science Direct, ACS, Wiley, CNKI, Baidu Scholar, Google Scholar, and ancient materia medica.

Trametes Robiniophila Murr (Huaier), a traditional Chinese medicine, has demonstrated significant efficacy in the clinical treatment of various tumors. The primary bioactive constituents of Huaier consist of fungal-derived compounds, including polysaccharides, proteins, ketones, alkaloids, and minerals. The research findings demonstrate that Huaier serves as a reliable adjunctive therapeutic agent by effectively inhibiting cancer cell proliferation, inducing apoptosis in cancer cells, suppressing tumor metastasis, regulating tumor stem cells and immune function. Therefore, it exerts a potent anti-tumor effect when used in conjunction with conventional anti-cancer therapies.

The analysis of traditional uses, phytochemical composition, and pharmacological activity reveals that Huaier exhibits significant potential as a medicinal plant with diverse pharmacological effects. Owing to its numerous advantages, Huaier holds immense promise for application in the domains of tumor prevention and treatment, enhancing both survival time and quality of life among cancer patients.

Hepatic, biliary, and pancreatic cancer pose significant challenges in the field of digestive system diseases due to their highly malignant nature. Traditional Chinese medicine (TCM) has gained attention as a potential therapeutic approach with long-standing use in China and well-recognized clinical benefits. In this review, we systematically summarized the clinical applications of TCM that have shown promising results in clinical trials in treating hepatic, biliary, and pancreatic cancer. We highlighted several commonly used TCM therapeutics with validated efficacy through rigorous clinical trials, including Huaier Granule, Huachansu, and Icaritin. The active compounds and their potential targets have been thoroughly elucidated to offer valuable insights into the potential of TCM for anti-cancer drug discovery. We emphasized the importance of further research to bridge the gap between TCM and modern oncology, facilitating the development of evidence-based TCM treatment for these challenging malignancies.

Although Huaier granules can be used as prospective anti-cholangiocarcinoma drugs, the mechanism of action of Huaier granules in cholangiocarcinoma is not clear. The anti-cholangiocarcinoma effect of Huaier granules was validated in cell line research. In vitro experiments were conducted to investigate the signalling pathways affected by Huaier in CCA cells.

Real-time quantitative PCR (RT‒qPCR) and Western blot analysis were performed to analyse gene expression in CCA cells. MTT assays, scratch tests, and Transwell assays were used to explore the effects on the proliferation and metastasis of CCA cells. Chromatin immunoprecipitation assays were performed to reveal the potential underlying mechanisms involved. Twist1 was upregulated in human CCA tissues. In addition, its expression levels were negatively related to FBP1 expression levels. Mechanistically, Twist1 can bind to the region of the FBP1 promoter to reduce its expression. Huaier plays an indispensable role in suppressing Twist1 expression to inhibit the Twist1/FBP1/Wnt/β-catenin axis. Then, we verified the effect of Huaier in vitro.

These findings suggested that Huaier granules were capable of inhibiting CCA development through regulating the Twist1/FBP1/Wnt/β-catenin signalling axis and provided a novel orientation for the development of novel anti-CCA drugs.

Gemcitabine is the first-line chemotherapy drug that can easily cause chemotherapy resistance. Huaier is a traditional Chinese medicine and shows an antitumor effect in pancreatic cancer, but whether it can enhance the gemcitabine chemotherapeutic response and the potential mechanism remain unknown.

This study was performed to explore the effect of Huaier in promoting the tumor-killing effect of gemcitabine and elucidate the possible mechanism in pancreatic cancer.

Cell Counting Kit-8 assays and colony formation assays were used to detect proliferation after different treatments. Protein coimmunoprecipitation was applied to demonstrate protein interactions. Nuclear protein extraction and immunofluorescence were used to confirm the intracellular localization of the proteins. Western blotting was performed to detect cell proliferation-related protein expression or cancer stem cell-associated protein expression. Sphere formation assays and flow cytometry were used to assess the stemness of pancreatic cancer cells. The in vivo xenograft model was used to confirm the inhibitory effect under physiological conditions, and immunohistochemistry was used to detect protein expression.

Huaier suppressed the proliferation and stem cell-like properties of pancreatic cancer cells. We found that Huaier suppressed the expression of forkhead box protein M1 (FoxM1). In addition, Huaier inhibited FoxM1 function by blocking its nuclear translocation. Treatment with Huaier reversed the stemness induced by gemcitabine in a FoxM1-dependent manner. Furthermore, we verified the above results by an in vivo study, which reached the same conclusion as those in vitro.

Overall, this study illustrates that Huaier augments the tumor-killing effect of gemcitabine through suppressing the stemness induced by gemcitabine in a FoxM1-dependent way. These results indicate that Huaier can be applied to overcome gemcitabine resistance.

Lenvatinib (LVN) is a potentially effective multiple-targeted receptor tyrosine kinase inhibitor approved for treating hepatocellular carcinoma, metastatic renal cell carcinoma and thyroid cancer. Nonetheless, poor pharmacokinetic properties including poor water solubility and rapid metabolic, complex tumor microenvironment, and drug resistance have impeded its satisfactory therapeutic efficacy. This article comprehensively reviews the uses of nanotechnology in LVN to improve antitumor effects. With the characteristic of high modifiability and loading capacity of the nano-drug delivery system, an active targeting approach, controllable drug release, and biomimetic strategies have been devised to deliver LVN to target tumors in sequence, compensating for the lack of passive targeting. The existing applications and advances of LVN in improving therapeutic efficacy include improving longer-term efficiency, achieving higher efficiency, combination therapy, tracking and diagnosing application and reducing toxicity. Therefore, using multiple strategies combined with photothermal, photodynamic, and immunoregulatory therapies potentially overcomes multi-drug resistance, regulates unfavorable tumor microenvironment, and yields higher synergistic antitumor effects. In brief, the nano-LVN delivery system has brought light to the war against cancer while at the same time improving the antitumor effect. More intelligent and multifunctional nanoparticles should be investigated and further converted into clinical applications in the future.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality worldwide. HCC almost exclusively develops in patients with chronic liver disease, driven by a vicious cycle of liver injury, inflammation and regeneration that typically spans decades. A variety of new agents are in development for the treatment of the disease. Polysaccharide is important component of higher plants, membrane of the animal cell and the cell wall of microbes. It is also closely related to the physiological functions. Recently, there has been growing interest in polysaccharides as bioactive natural products, particularly in treating HCC. This paper provides a review of recent experimental and clinical studies on the effects and potential applications of polysaccharides in HCC treatment, aiming to offer theoretical insights and inspiration for further research on the bioactivity mechanisms of polysaccharides in HCC treatment.

The application of antifibrotic drugs to treat patients with chronic liver diseases who are receiving antiviral therapies for hepatocellular carcinoma (HCC) has not been established. Here, we aimed to assess the impact of the Traditional Chinese Medicine Fuzheng Huayu (FZHY) on the occurrence of HCC in patients with hepatitis B virus-related compensated cirrhosis receiving the antiviral drug entecavir (ETV).

A multicenter retrospective cohort study was performed. Compensated liver cirrhosis patients were divided into the ETV+FZHY group or the ETV group according to treatment. The cumulative incidence of HCC was analyzed using Kaplan-Meier and log-rank tests. Propensity score matching was used for confounding factors. Stratified analysis and Cox regression were used to determine the effects of FZHY on the occurrence of HCC and liver function decompensation.

Out of 910 chronic hepatitis B patients, 458 were in the ETV+FZHY group and 452 were in the ETV group. After propensity score matching, the 5-year cumulative incidence of HCC was 9.8% in the ETV+FZHY group and 21.8% in the ETV group (p<0.01). The adjusted hazard ratio for HCC was 0.216 (0.108, 0.432) when FZHY treatment was >36 months. Age, diabetes, alanine aminotransferase, γ-glutamyl transpeptidase, albumin, hepatitis B e-antigen, and fibrosis 4 score were associated with the occurrence of HCC. FZHY decreased the risk of HCC in patients aged >45 years with a hepatitis B virus DNA level of ≥2,000 IU/l.

Adjunctive FZHY treatment reduced HCC occurrence in patients with hepatitis B virus cirrhosis who were treated with ETV, possibly due to the antifibrotic properties of FZHY.

Most patients with hepatocellular carcinoma (HCC) have a poor prognosis. Hepatectomy and local ablation are the main curative treatments for HCC. Nevertheless, the recurrence rate after hepatectomy or ablation is up to 70%, which seriously affects patient prognosis. Several adjuvant therapies have been explored to reduce postoperative recurrence. However, although a variety of adjuvant therapies have been shown to reduce the recurrence rate and improve overall survival, a standard consensus of national HCC guidelines for adjuvant treatment is lacking. Therefore, there are significant differences in the recommendations for adjuvant therapy for HCC between the Eastern and Western guidelines. A variety of adjuvant treatment methods, such as antiviral therapy, transarterial chemoembolization or traditional Chinese medicine, are recommended by the Chinese HCC guidelines. However, Western guidelines make few recommendations other than antiviral therapy. Adjuvant immune checkpoint inhibitors are recommended only in the recently updated American Association for the Study of Liver Diseases guidelines. This review summarized the existing adjuvant therapy options after curative hepatectomy or ablation and discusses several important dilemmas of adjuvant treatments.

This study aimed to elucidate the therapeutic effects of Huaier granules on hepatocellular carcinoma (HCC) within the Milan criteria in patients who underwent microwave ablation (MWA).

A total of 228 patients were included, with 97 in the Huaier group and 131 in the control group. We evaluated progression-free survival (PFS), overall survival (OS), and extrahepatic metastasis survival (EMS) using Kaplan-Meier (KM) curves with a log-rank test. Propensity Score Matching (PSM) and Stabilized Inverse Probability of Treatment Weighting (IPTW) were performed to minimize selection and confounding biases.

Following PSM, the 1-, 3-, and 5-year PFS rates in the Huaier and control groups were 83.5% vs 70.7%, 57.7% vs 42.6%, and 43.6% vs 31.9% (p = 0.030), respectively. The 1-, 3-, and 5-year OS rates were 98.9% vs 95.6%, 83.9% vs 72.3%, and 72.2% vs 53.7% (p = 0.023), respectively. The corresponding 1-, 3-, and 5-year EMS rates were 98.9% vs 93.4%, 91.7% vs 83.7%, and 91.7% vs 78.5% (p = 0.039), respectively. Stabilized IPTW analysis of KM curves yielded results similar to those of the PSM analysis. Additionally, administering Huaier granules for at least 6 months significantly improved PFS and OS.

Huaier granules can reduce the risk of recurrence and improve the OS of patients with HCC within the Milan criteria following MWA. Administering Huaier granules for over 6 months proved beneficial.

Background: This study will explore the therapeutic value of traditional Chinese medicine (TCM) in Hepatocellular Carcinoma (HCC) through meta-analysis, combined with network pharmacology analysis. Methods: The results of randomized controlled trials on TCM and HCC were retrieved and summarized from multiple databases. The effective active com-pounds and target genes of the high-frequency TCM were obtained using the TCMSP database, and disease targets of HCC were acquired through the public disease database. The network pharmacology analysis was used to get the core genes and investigate the potential oncogenic molecular mechanism. Results: A total of 14 meta-analysis studies with 1,831 patients suggested that therapy combined TCM is associated with better clinical efficacy and survival prognosis, as well as avoiding many adverse events. A total of 156 compounds, 247 herbal target genes and 36 core genes were identified. The function analysis suggested above genes may participate development in HCC through regulating some pathways, such as HIF-1 pathway and PD-L1 immune-related pathway. Conclusion: TCM, as a novel, safe, and effective multi-mechanism therapy, holds greater value in the treatment of HCC.

For resectable hepatocellular carcinoma (HCC), radical hepatectomy is commonly used as a curative treatment. However, postoperative recurrence significantly diminishes the overall survival (OS) of HCC patients, especially with microvascular invasion (MVI) as an independent high-risk factor for recurrence. While some studies suggest that postoperative adjuvant therapy may decrease the risk of recurrence following liver resection in HCC patients, the specific role of adjuvant therapies in those with MVI remains unclear.

To conduct a network meta-analysis (NMA) to evaluate the efficacy of various adjuvant therapies and determine the optimal adjuvant regimen.

A systematic literature search was conducted on PubMed, EMBASE, and Web of Science until April 6, 2023. Studies comparing different adjuvant therapies or comparing adjuvant therapy with hepatectomy alone were included. Hazard ratios (HRs) with 95% confidence intervals were used to combine data on recurrence free survival and OS in both pairwise meta-analyses and NMA.

Fourteen eligible trials (2268 patients) reporting five different therapies were included. In terms of reducing the risk of recurrence, radiotherapy (RT) [HR = 0.34 (0.23, 0.5); surface under the cumulative ranking curve (SUCRA) = 97.7%] was found to be the most effective adjuvant therapy, followed by hepatic artery infusion chemotherapy [HR = 0.52 (0.35, 0.76); SUCRA = 65.1%]. Regarding OS improvement, RT [HR: 0.35 (0.2, 0.61); SUCRA = 93.1%] demonstrated the highest effectiveness, followed by sorafenib [HR = 0.48 (0.32, 0.69); SUCRA = 70.9%].

Adjuvant therapy following hepatectomy may reduce the risk of recurrence and provide a survival benefit for HCC patients with MVI. RT appears to be the most effective adjuvant regimen.

The study aimed to investigate the potential of traditional Chinese medicine (TCM) in reducing the risk of macrovascular invasion (MVI) in Chinese patients with hepatocellular carcinoma (HCC). This retrospective analysis involved 2,267 HCC patients treated at our hospital. Propensity score (PS) matching was used to compare TCM users (n = 485) with non-users (n = 485) in terms of age, Barcelona Clinic Liver Cancer (BCLC) staging, type of treatment, and AFP. The impact of TCM on the hazard ratio (HR) of MVI was evaluated using a Cox multivariate regression model. The efficacy of TCM therapy on MVI was further examined using the log-rank test. The analysis revealed that TCM medication was a significant protective factor for MVI in HCC patients, as evidenced by the Cox analysis (adjusted HR = 0.496, 95% CI: 0.387-0.635, p < 0.001). After PS matching, the Kaplan-Meier curve demonstrated a lower occurrence rate of MVI in TCM users compared to non-users. The study findings suggest that TCM treatment has the potential to decrease the incidence of MVI in HCC patients, irrespective of etiology, BCLC staging, liver function, or treatment type. Notably, as the use of TCM increased, the percentage of MVI in patients showed a gradual decrease, indicating the potential of TCM therapy as a successful strategy for preventing MVI.

To investigate the effects of Pien Tze Huang (PZH) on the migration and invasion of HCC cells and underlying molecular mechanism.

Cell counting kit-8 (CCK-8) was applied to evaluate the cell viabilities of SMMC-7721, SK-Hep-1, C3A and HL-7702 (6 × 103 cells/well) co-incubated with different concentrations of PZH (0, 0.2, 0.4, 0.6, 0.8 mg/mL) for 24 h. Transwell, wound healing assay, CCK-8 and Annexin V-FITC/PI staining were conducted to investigate the effects of PZH on the migration, invasion, proliferation and apoptosis of SK-Hep-1 and SMMC-7721 cells (650 µ g/mL for SK-Hep-1 cells and 330 µ g/mL for SMMC-7721 cells), respectively. In vivo, lung metastasis mouse model constructed by tail vein injection of HCC cells was used for evaluating the anti-metastasis function of PZH. SK-Hep-1 cells (106 cells/200 µ L per mice) were injected into B-NDG mice via tail vein. Totally 8 mice were randomly divided into PZH and control groups, 4 mice in each group. After 2-d inoculation, mice in the PZH group were administered with PZH (250 mg/kg, daily) and mice in the control group received only vehicle (PBS) from the 2nd day after xenograft to day 17. Transcriptome analysis based on RNA-seq was subsequently used for deciphering anti-tumor mechanism of PZH. Quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot were applied to verify RNA-seq results. Luciferase reporter assay was performed to examine the transcriptional activity of yes-associated protein (YAP).

PZH treatment significantly inhibited the migration, invasion, proliferation and promoted the apoptosis of HCC cells in vitro and in vivo (P<0.01). Transcriptome analysis indicated that Hippo signaling pathway was associated with anti-metastasis function of PZH. Mechanical study showed PZH significantly inhibited the expressions of platelet derived growth factor receptor beta (PDGFRB), YAP, connective tissue growth factor (CCN2), N-cadherin, vimentin and matrix metallopeptidase 2 (MMP2, P<0.01). Meanwhile, the phosphorylation of YAP was also enhanced by PZH treatment in vitro and in vivo. Furthermore, PZH played roles in inhibiting the transcriptional activity of YAP.

PZH restrained migration, invasion and epithelial-mesenchymal transition of HCC cells through repressing PDGFRB/YAP/CCN2 axis.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide. Hepatectomy remains the first-line treatment for patients with resectable HCC. However, the reported recurrence rate of HCC at 5 years after surgery is between 50% and 70%. Tumor-related factors, including tumor size, number and differentiation, and underlying liver disease are well-known risk factors for recurrence after treatment. In addition to tumor-related factors, ever-increasing amounts of studies are finding that the tumor microenvironment also plays an important role in the recurrence of HCC, including systemic inflammatory response and immune regulation. Based on this, some inflammatory and immune markers were used in predicting postoperative cancer recurrence. These include neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, cytotoxic T cells, and regulatory T cells, among others. In this review, we summarized the inflammatory and immune markers that affect recurrence after HCC resection in order to provide direction for adjuvant therapy after HCC resection and ultimately achieve the goal of reducing recurrence.

Huaier (Trametes robiniophila Murr), a traditional Chinese medicinal fungus, possesses potent anticancer efficacy and has been used as an adjuvant medication for liver, breast, gastric, intestinal, and non-small cell lung cancer (NSCLC). However, the potential regulatory functions and underlying molecular mechanisms of Huaier in cisplatin resistance of NSCLC remain unknown.

To evaluate the potential regulatory functions and underlying molecular mechanisms of Huaier in cisplatin resistance of NSCLC.

In vitro and in vivo experiments were employed to evaluate the regulatory functions of Huaier in cisplatin-resistant NSCLC cells. Transcriptome sequencing and validation analyses was undertaken to identify the downstream targets of Huaier. Network pharmacology, ultra-performance liquid chromatography-mass spectroscopy, and in vitro and in vivo experiments were performed to identify key small molecule drug candidates in Huaier and the regulatory mechanisms these employ to suppress cisplatin resistance in NSCLC.

Huaier suppressed cisplatin resistance and cancer cell stemness in cisplatin-resistant NSCLC cells, both in vitro and in vivo. Mechanistically, Huaier could suppress expression of interleuken-8 (IL-8) through inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) and activator protein-1 (AP-1), two key transcription factors responsible for the activation of IL-8 transcription. Kaempferol was identified as one of the key small molecule compounds in Huaier that could suppress cisplatin resistance by inhibiting the phosphorylation and nuclear translocation of proto-oncogene c-Jun (JUN) by binding and inhibiting the kinase activity of c-Jun N-terminal protein kinase (JNK).

Huaier suppressed cisplatin resistance of NSCLC cells by inhibiting the JNK/JUN/IL-8 signaling pathway.

Breast cancer is one of the most common female malignant tumors today and represents a serious health risk for women. Although the survival rate and quality of life of patients with breast cancer are improving with the continuous development of medical technology, metastasis, recurrence, and drug resistance of breast cancer remain a significant problem. Huaier, a traditional Chinese medicine (TCM) fungus, is a type of Sophora embolism fungus growing on old Sophora stems. The polysaccharides of Trametes robiniophila Murr (PS-T) are the main active ingredient of Huaier. There is increasing evidence that Huaier has great potential in breast cancer treatment, and its anti-cancer mechanism may be related to a variety of biological activities, such as the inhibition of cell proliferation, metastasis, tumor angiogenesis, the promotion of cancer cell death, and regulation of tumor-specific immunity. There is growing evidence that Huaier may be effective in the clinical treatment of breast cancer. This review systematically summarizes the basic and clinical studies on the use of Huaier in the treatment of breast cancer, providing useful information to guide the clinical application of Huaier and future clinical studies.

Traditional herbal medicine practitioners in the Ashanti region of Ghana use the fruit peels of Citrus limon (L.) Osbeck (C. limon) in preventive and curative treatment of many cancers including liver cancer. This ethnobotanical claim remains to be verified scientifically. Aim of the Study. This study investigated prophylactic hepatoprotective and anti-HCC effects of C. limon peel extract (LPE) in CCl4/olive oil-induced HCC-like rats.

After preparation of LPE, it was subjected to phytochemical screening using standard phytochemical methods. A total of 30 healthy adult male Sprague-Dawley rats (weighing 150-200 g) were randomly assigned into six groups of 5 rats each. Rats in the control group received olive oil (5 mL/kg ip) twice weekly for 16 weeks. Rats in the model group received CCl4/olive oil (2 mL/kg, ip) twice weekly for 16 weeks. Rats in capecitabine (10 mg/kg po) and LPE (50, 100, and 200 mg/kg po) groups received CCl4/olive oil (2 mL/kg, i.p) in the morning and their respective treatments in the afternoon twice a week for 16 weeks. Rats in all groups had free access to food and water ad libitum. Body weight and survival rates were monitored. Rats were sacrificed under deep anesthesia, blood was collected, and liver and other organs were isolated. Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyltransferase (GGT), prothrombin time, bilirubin, C-reactive protein (CRP), alpha- (α-) fetoprotein (AFP), and liver histology were assessed.

Alkaloids, tannins, flavonoids, terpenoids, and saponins were detected in LPE. Model rats demonstrated increased serum levels of AFP, CRP, ALP, GGT, ALT, and AST, prothrombin time, total bilirubin, direct bilirubin, blood lymphocyte, and monocyte counts, but decreased serum albumin and total protein compared to control rats. Unlike the control, model rats demonstrated fat accumulation in periportal and centrilobular hepatocytes and neoplastic transformation. Semiquantitation of periodic acid Schiff- (PAS-) stained liver sections showed decreased glycogen storage in hepatocytes of model rats compared to control rats. Compared to the model, LPE treatment protected against CCl4-induced hepatocarcinogenesis, which was evidenced by decreased AFP, CRP, liver enzymes, total and direct bilirubin, prothrombin time, and blood lymphocyte and monocyte counts; attenuation of fat accumulation; and increased glycogen storage, albumin, and total protein.

LPE abates CCl4-induced hepatocarcinogenesis by attenuating liver inflammation and improving metabolic, biosynthetic, and detoxification functions of the liver. The prophylactic hepatoprotective and anti-hepatocarcinogenic effects of LPE are attributable to its phytochemical composition raising hopes of finding potential anticancer bioactive compounds from C. limon fruit peels.

Huaier (Trametes robiniophila Murr), a traditional Chinese medicine, is widely used in China as a complementary and alternative therapy to treat hepatocellular carcinoma (HCC). Past studies have shown that Huaier can arrest the cell cycle, promote apoptosis and inhibit the proliferation of cancer cells. However, how it regulates the metabolism of HCC is still unclear.

This study explores the metabolic-related function of Huaier in treating HCC with an in-silico approach.

A network pharmacology and bioinformatics-based approach was employed to investigate the molecular pathogenesis of metabolic reprogramming in HCC with Huaier. The compounds of Huaier were obtained from public databases. Oral bioavailability and drug likeness were screened using the TCMSP platform. The differential gene expressions between HCC and non-tumor tissue were calculated and used to find the overlap from the targets of Huaier. The enrichment analysis of the overlapped targets by Metascape helped filter out the metabolism-related targets of Huaier in treating HCC. Protein-protein interaction (PPI) network construction and topological screening revealed the hub nodes. The prognosis and clinical correlation of these targets were validated from the cancer genome atlas (TCGA) database, and the interactions between the hub nodes and active ingredients were validated by molecular docking.

The results showed that Peroxyergosterol, Daucosterol, and Kaempferol were the primary active compounds of Huaier involved in the metabolic reprogramming of HCC. The top 6 metabolic targets included AKR1C3, CYP1A1, CYP3A4, CYP1A2, CYP17A1, and HSD11B1. The decreased expression of CYP3A4 and increased expression of AKR1C3 were related to the poor overall survival of HCC patients. The molecular docking validated that Peroxyergosterol and Kaempferol exhibited the potential to modulate CYP3A4 and AKR1C3 from a computational perspective.

This study provided a workflow for understanding the mechanism of Huaier in regulating the metabolic reprogramming of HCC.

Fufang Banmao capsule (FFBM), a traditional Chinese medicine, has been used to treat primary liver cancer (PLC) for several years. However, the bioactive ingredients, and mechanism of FFBM for treating PLC remains unclear. Our objective is to utilize network pharmacology to investigate these aspects and subsequently validate their effectiveness through clinical data.

The FFBM ingredients were obtained from the HERB database and screened for bioactive ingredients using the SwissTargetPrediction database. The PharmMapper and GEO database were used to acquire targets and differentially expressed genes (DEGs) for FFBM and PLC, respectively. Common targets were identified using Venn diagrams, followed by enrichment and protein-protein interaction (PPI) analysis. Furthermore, the Cytoscape software was utilized to identify Hub genes and construct the ingredienttarget- pathway network. Subsequently, patients diagnosed with unresectable PLC who underwent transcatheter arterial chemoembolization (TACE) at our hospital between January 2008 and December 2019 were retrospectively collected. Finally, Cox analysis was conducted to reveal the role of FFBM in the treatment of unresectable PLC.

FFBM had 232 targets, and PLC had 1582 DEGs. HSP90AA1 and SRC were identified as crucial targets. Alpha-santalol, glycyrrhizin, and morroniside were identified as the top three bioactive ingredients. Enrichment analysis revealed a significant connection between FFBM utilization for treating PLC and multiple pathways, such as chemical carcinogenesis, PI3K-AKT, Rap1, FoxO, MAPK, and VEGF pathway. Clinical data revealed that consuming FFBM significantly improved the prognosis of unresectable PLC with a hazard ratio of 0.69.

Our study identified the bioactive ingredients of FFBM and its potential mechanisms for treating PLC. Additionally, we validated the effectiveness through clinical data.

Combination therapy is an effective method for augmenting the efficacy of immune checkpoint inhibitors (ICIs). Huaier is a commonly used Chinese patent medicine with substantial antitumor effects. The combination of Huaier and ICIs may increase the efficacy of ICIs against hepatocellular carcinoma (HCC).

The major components of Huaier were detected by high-performance liquid chromatography-mass spectrometry. The optimal antitumor dose of Huaier was investigated in H22-bearing mice. Next, Huaier was combined with anti-CD8α antibody (Ab) or anti-PD-L1 Ab to observe the antitumor effect. The safety of these combination drugs was evaluated through blood biochemical tests and hematoxylin and eosin staining of histological sections. RT-qPCR, immunohistochemistry, flow cytometry, and transcriptome sequencing were performed to investigate the potential action mechanism of anti-PD-L1 Ab combined with Huaier against HCC.

HPLC-MS/MS identified 333 components of Huaier, including carboxylic acids and derivatives, thienothiophenes, phenols, flavonoids and so on. Huaier exhibited significant antitumor effects, with the strongest effect noted at a dose of 4 g/kg. Huaier boosted CD8+ T cells infiltration into the tumor. Next, CD8+ T cells were depleted by with anti-CD8α Ab, and the antitumor effect of Huaier was suppressed. Flow cytometry results revealed that CD8+ T cells were reduced in the Huaier+anti-CD8α Ab group, with the antitumor effect of this group being inhibited. This indicated that CD8+ T cells were key players in the antitumor activity of Huaier. Meanwhile, Huaier inhibited microvessel density (MVD), downregulated vascular endothelial growth factor A (VEGFA), and upregulated PD-L1 in tumor tissues. Finally, Huaier combined with anti-PD-L1 Ab exhibited a greater antitumor effect in the H22-bearing mice. And the results of liver and kidney function tests and histological section analysis unveiled that the safety of these drugs was excellent. According to the transcriptome sequencing results, Huaier combined with anti-PD-L1 Ab possibly exerted anti-HCC effects through immunomodulation, immune response, and so on.

Huaier exhibited a significant antitumor effect. It promoted CD8+ T cells infiltration, upregulated PD-L1 expression, downregulated VEGFA expression, and inhibited MVD, thereby playing a significant antitumor immunoregulatory effect. The combination of Huaier and anti-PD-L1 Ab has significant antitumor effects, and this regimen has good safety. Therefore, Huaier combined with anti-PD-L1 Ab is a promising therapeutic approach against HCC.

Hepatocellular carcinoma (HCC) is a malignant tumor of the digestive system that poses a serious threat to human life and health. Chemotherapeutic drugs commonly used in the clinic have limited efficacy and heavy adverse effects. Therefore, it is imperative to find effective and safe alternatives, and natural polysaccharides (NPs) fit the bill. This paper summarizes in detail the anti-HCC activity of NPs in vitro, animal and clinical trials. Furthermore, the addition of NPs can reduce the deleterious effects of chemotherapeutic drugs such as immunotoxicity, bone marrow suppression, oxidative stress, etc. The potential mechanisms are related to induction of apoptosis and cell cycle arrest, block of angiogenesis, invasion and metastasis, stimulation of immune activity and targeting of MircoRNA. And on this basis, we further elucidate that the anti-HCC activity may be related to the monosaccharide composition, molecular weight (Mw), conformational features and structural modifications of NPs. In addition, due to its good physicochemical properties, it is widely used as a drug carrier in the delivery of chemotherapeutic drugs and small molecule components. This review provides a favorable theoretical basis for the application of the anti-HCC activity of NPs.

Curcumin (CUR) has good antitumor effects, but its poor aqueous solubility severely limits its clinical application and the systemic nonspecific distribution of the free drug in tumor patients is a key therapeutic challenge. In order to overcome the limitations of free drugs and improve the therapeutic efficacy, we developed novel galactosylated chitosan (GC)-modified nanoparticles (GC@NPs) based on poly (ethylene glycol) methyl ether-block-poly (lactide-co-glycolide) (PEG-PLGA), which can target asialoglycoprotein receptor (ASGPR) expressed on hepatocellular carcinoma cells and have excellent biocompatibility. The results showed that the drug loading (DL) of CUR was approximately 4.56 %. A favorable biosafety profile was maintained up to concentrations of 500 μg/mL. Furthermore, in vitro cellular assays showed that GC@NPs could be efficiently internalized by HepG2 cells via ASGPR-mediated endocytosis and successfully released CUR for chemotherapy. More importantly, in vivo anti-tumor experiments revealed that GC@NPs were able to accumulate effectively within tumor sites through EPR effect and ASGPR-mediated endocytosis, leading to superior inhibition of tumor growth compared to free CUR. Overall, GC@NPs are a promising CUR nanocarrier for enhanced tumor therapy with a good biosafety profile.

Currently, hepatocellular carcinoma (HCC) is characterized by its unfavorable prognosis and resistance to conventional chemotherapy and radiotherapy. Drug repositioning, an approach aimed at identifying novel therapeutic applications for existing drugs, presents a cost-effective strategy for developing new anticancer agents. We explored the anticancer properties of Ezetimibe, a widely used oral lipid-lowering drug, in the context of HCC. Our findings demonstrate that Ezetimibe effectively suppresses HCC cell proliferation through paraptosis, an apoptotic-independent cell death pathway. The examination of HCC cells lines treated with Ezetimibe using light microscopy and transmission electron microscopy (TEM) showed cytoplasmic vacuolation in the perinuclear region. Notably, the nuclear membrane remained intact in both Ezetimibe-treated and untreated HCC cell lines. Probe staining assays confirmed that the cytoplasmic vacuoles originated from dilated endoplasmic reticulum (ER) compartments rather than mitochondria. Furthermore, a dose-dependent accumulation of reactive oxygen species (ROS) was observed in Ezetimibe-treated HCC cell lines. Co-treatment with the general antioxidant NAC attenuated vacuolation and improved cell viability in Ezetimibe-treated HCC cells. Moreover, Ezetimibe induced paraptosis through proteasome activity inhibition and initiation of the unfolded protein response (UPR) in HCC cell lines. In our in vivo experiment, Ezetimibe significantly impeded the growth of HCC tumors. Furthermore, when combined with Sorafenib, Ezetimibe exhibited a synergistic antitumor effect on HCC cell lines. Mechanistically, Ezetimibe induced paraptosis by targeting NPC1L1 to inhibit the PI3K/AKT/mTOR signaling pathway. In conclusion, our study highlights the potential of Ezetimibe as an anticancer agent by triggering paraptosis in HCC cells.

According to the Barcelona Clinic Liver Cancer (BCLC) system, radical resection of early stage primary hepatocellular carcinoma (HCC) mainly includes liver transplantation, surgical resection, and radiofrequency ablation (RFA), which yield 5-year survival rates of about 70-79%, 41.3-69.5%, and 40-70%, respectively. The tumor-free 5-year rate for HCC patients undergoing radical resection only reach up to 13.7 months, so the prevention of recurrence after radical resection of HCC is very important for the prognosis of patients. The traditional Chinese medicine (TCM) takes the approach of multitarget and overall-regulation to treat tumors, it can also independently present the "component-target-pathway" related to a particular disease, and its systematic and holistic characteristics can provide a personalized therapy based on symptoms of the patient by treating the patient as a whole. TCM as postoperative adjuvant therapy after radical resection of HCC in Barcelona Clinic liver cancer A or B stages, and the numerous clinical trials confirmed that the efficacy of TCM in the field of HCC has a significant effect, not only improving the prognosis and quality of life but also enhancing patient survival rate. However, with the characteristics of multi-target, multi-component, and multi-pathway, the specific mechanism of Chinese medicine in the treatment of diseases is still unclear. Because of the positive pharmacological activities of TCM in combating anti-tumors, the mechanism studies of TCM have demonstrated beneficial effects on the regulation of immune function, chronic inflammation, the proliferation and metastasis of liver cancer cells, autophagy, and cell signaling pathways related to liver cancer. Therefore, this article reviews the mechanism of traditional Chinese medicine in reducing the recurrence rate of HCC after radical resection.

Primary liver cancer, of which around 75-85% is hepatocellular carcinoma in China, is the fourth most common malignancy and the second leading cause of tumor-related death, thereby posing a significant threat to the life and health of the Chinese people.

Since the publication of Guidelines for Diagnosis and Treatment of Primary Liver Cancer in China in June 2017, which were updated by the National Health Commission in December 2019, additional high-quality evidence has emerged from researchers worldwide regarding the diagnosis, staging, and treatment of liver cancer, that requires the guidelines to be updated again. The new edition (2022 Edition) was written by more than 100 experts in the field of liver cancer in China, which not only reflects the real-world situation in China but also may reshape the nationwide diagnosis and treatment of liver cancer.

The new guideline aims to encourage the implementation of evidence-based practice and improve the national average 5-year survival rate for patients with liver cancer, as proposed in the "Health China 2030 Blueprint."
