Objectives: Effective treatments for diarrhea-type irritable bowel syndrome (IBS-D) are limited. Hangeshashinto (HST), an anti-inflammatory Kampo medicine, may offer benefits but its efficacy for IBS-D requires further investigation. This study evaluated IBS-D symptom improvement and gut microbiota changes following HST administration.

Background/aims: Digestive disorders of gut-brain interaction (DGBI) are very common, predominant in females, and usually associated with intestinal barrier dysfunction, dysbiosis, and stress. We previously found that females have increased susceptibility to intestinal barrier dysfunction in response to acute stress. However, whether this is associated with changes in the small bowel microbiota remains unknown.

Introduction: IBS is a prevalent gut-brain interaction disorder characterized by abdominal pain and altered bowel habits, significantly affecting quality of life (QoL). IBS contributes to substantial work absenteeism and economic burdens and often coexists with other somatic and psychiatric conditions, with psychological well-being being a critical determinant of QoL. IBS sufferers often turn to MT due to dissatisfaction with conventional treatments.

Unlabelled: In the gut, microRNAs (miRNAs) produced by intestinal epithelial cells are secreted into the lumen and can shape the composition and function of the gut microbiome. Crosstalk between gut microbes and the host plays a key role in irritable bowel syndrome (IBS) and inflammatory bowel diseases, yet little is known about how the miRNA-gut microbiome axis contributes to the pathogenesis of these conditions. Here, we investigate the ability of miR-21, a miRNA that we found decreased in fecal samples from IBS patients, to associate with and regulate gut microbiome function.

Introduction: Ulcerative colitis (UC), a form of inflammatory irritable bowel disease, is characterized by a recurrent and persistent nonspecific inflammatory response. Polydatin (PD), a natural stilbenoid polyphenol with potent properties, exhibits unexpected beneficial effects beyond its well-documented anti-inflammatory and antioxidant activities. In this study, we presented evidence that PD confers protection against dextran sodium sulfate (DSS)-induced ulcerative colitis.
