This study investigated the efficacy, underlying mechanism, and responsible active compounds of the traditional Chinese medicinal prescription Chaihuang Qingyi Huoxue granule (CHQY) in treating SAP-induced intestinal mucosal barrier injury. SAP was established in Sprague-Dawley rats via intra-pancreaticobiliary duct infusion of sodium taurocholate, followed by oral CHQY administration (3.15 g/kg every 6 h for 12 and 24 h). Blood and tissues were harvested to assess the severity of pancreatitis, intestinal mucosal barrier integrity, and extent of inflammatory injury.

Our results showed that CHQY treatment effectively mitigated SAP-induced intestinal mucosal injury, as evidenced by improved intestinal epithelial structure, decreased serum levels of intestinal injury markers (d-lactic acid, diamine oxidase, I-FABP, and Zonulin), restored expression of the tight junction protein ZO-1, and reduced serum endotoxin levels. Furthermore, CHQY administration suppressed the expression of proinflammatory mediator HMGB1, its receptor TLR4, and downstream NF-κB signaling in the intestine, leading to downregulated intestinal IL-1β expression and reduced circulating TNF-α and IL-6.
