Letter to the Editor: Integrative mechanistic exploration in gastrointestinal therapeutics: Exemplified by Chaihu-Shugan-San for chronic atrophic gastritis

Abstract

Gastroenterology is embracing integrative research, bridging traditional therapies with modern biomedical science. Chronic atrophic gastritis (CAG), a significant precancerous condition, exemplifies the need for such approaches, as current management strategies remain partially effective. In this context, Song et al published in the recent issue of the World Journal of Gastroenterology provided a compelling case study that systematically investigated the classic traditional Chinese medicine formula, Chaihu-Shugan-San, using network pharmacology prediction, molecular docking, in vivo validation in an N-methyl-N’-nitro-N-nitrosoguanidine-induced rat model, and 16S rRNA sequencing of gut microbiota. The research demonstrated that Chaihu-Shugan-San alleviates CAG by inhibiting nuclear factor kappa B-mediated inflammatory cascades and apoptosis, while promoting a favorable shift in gut microbial ecology. This editorial appraises this study design as a model for the mechanistic exploration of complex botanicals, highlighting its strengths in target identification and multi-omics integration. It critically discusses inherent limitations, including the translational gap between rodent models and human pathophysiology, and the lack of adjustment for key confounders, such as Helicobacter pylori status. This article argues that the future of gastrointestinal pharmacology in precancerous conditions lies in fostering integrative research, including clinical trials to validate preclinical findings, standardized phytochemical profiles, and composite biomarkers that combine inflammatory indices (systemic inflammatory response index), microbial signatures, and traditional diagnostic markers to guide personalized stage-specific interventions for CAG.

Core Tip: This paper emphasizes that the research of Song et al is an example of the integrated research of gastroenterology. Through the combination of network pharmacology, experimental validation and microbiome analysis, this study clarified how Chaihu-Shugan-San can improve chronic atrophic gastritis by double inhibiting inflammation and apoptosis driven by nuclear factor kappa B, and regulating intestinal flora. This paper critically evaluates this methodology as a blueprint for future research on complex botanical drugs, and emphasizes the need for subsequent clinical trials, standardization of phytochemistry, and the development of integrated biomarker groups, in order to translate these mechanistic insights into personalized clinical practice for precancerous lesions.
