Summary
Diarrhea irritable bowel syndrome(IBS-D)has seriously affected health and quality of life of patients.It may be important pathogenesis in development and recurrence of the process of IBS-D,excessive endoplasmic reticulum stress (ERS) activated PERK(proteinkinaseR-like ERkinase,PERK)-eIF2a(eukaryotic translation initiation factor 2 alpha,eIF2a) pathway and damaged intestinal mucosal epithelial Barrier. Tongxieyaofang(TXYF) had obtained satisfactory effect in treating IBS-D in clinic and previous study, but it is unknown that herbal formula how to work.This project applies metabolomics method to detect plasma,urine and stool metabolites for patients before and after treatment, to determine the effects of the"multiple ingredients"of TXYF in body.
