摘要

Huang-Qi-Jian-Zhong-Tang (HQJZT) is a well-known traditional Chinese herbal formulation. This study aimed to investigate the duodenoprotective properties of HQJZT against Indomethacin (IND)-induced duodenal ulceration in rats, and the mechanisms involved, particularly through NF-κB and STAT signaling pathways. Our results showed that HQJZT completely protected the duodenal mucosa from ulceration caused by IND, as indicated by improved macroscopic and histological appearances. There was a significant decrease in ulcer index and microscopic score, an increase in villus height and crypt depth, and a normalization of the tissue architecture of the duodenum in rats following HQJZT treatment. Blood flow into the duodenal mucosa was significantly increased after HQJZT administration. HQJZT significantly increased PGE2 and NO levels in the duodenal mucosa. A significant reduction in the production of pro-inflammatory cytokines IL-1β, IL-6, and TNF-α was observed in the duodenal mucosa under treatment with HQJZT. Mechanistically, the administration of HQJZT significantly lowered the duodenal protein expression of inflammation-related genes, including p-NF-κB and p-IκBβ, compared with the ulcer control group. Furthermore, the STAT signaling pathway-related protein markers p-JAK and p-STAT were significantly reduced in the HQJZT (1.30 and 2.60 g/kg) groups. As a result of these findings, HQJZT alleviates duodenal mucosal ulcers caused by IND. A protective effect of HQJZT on duodenal ulcers is attributed to its ability to improve mucosal blood flow, stimulate the production of cytoprotective mediators, minimize proinflammatory cytokines, and block the activation of NF-κB and STAT signaling pathways.
