Effect and Mechanism of Baitouweng Decoction for Large Intestine Damp-heat Syndrome of Ulcerative Colitis

Formula-to-Syndrome Effect and Pharmacomicrobiomics Mechanism of Colon Delivery of Baitouweng Decoction for Treating Large Intestine Damp-heat Syndrome of Ulcerative Colitis

About This Trial

Baitouweng Decoction is traditionally used to treat large intestine damp-heat syndrome of ulcerative colitis (UC) by oral administration and rectal enema.The project applicant's invention of transendoscopic entral tubing (TET) has been used in Baitouweng Decoction for the treatment of UC across the whole colon, however, the efficacy have not been reported and the underlying mechanism is still unclear. Compared with oral and rectal enema, Baitouweng Decoction by colon TET can improve the therapeutic effect by increasing the concentration of drugs in the whole colon, which need to be verified. This project will reveal the prescription effect and drug-microbiome interaction mechanism of whole colon repeated administration of Baitouweng Decoction in the treatment of UC through clinical randomized controlled studies, deep intestinal dynamic sampling, integrated analysis of multi-omics and TCM prescription metabolomics studies, and provide key scientific basis for the establishment of a new approach of whole colon repeated administration of TCM and a new strategy for the treatment of UC.
