[Effects of Jiaweisinisan dispersion on content and gene expression of gastric tissue GASR and jejunal tissue VIPR2 of physical and mental stress model rat].

Objective: To observe the effects of Jiaweisini dispersion (JWSNS) on the ultrastructure of gastric mucosa, the content and gene expression of gastric antrum tissue gastrin receptor (GASR) and jejunal tissue vasoactive intestinal peptide receptor 2 (VIPR2) in chronic stress gastric ulcer rats, and to elucidate its mechanism.

Methods: 60 Wistar rats were randomly divided into normal group, model group, JWSNS large, medium, small dose groups, and omeprazole group, 10 rats in each group. Chronic stress method was used to establish the stress ulcer rat model.
