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.
Patients diagnosed with ulcerative colitis;
The patients are in mild to moderate active stage with Mayo score of 3-8.
Patients with damp-heat syndrome of large intestine according to TCM syndrome differentiation: according to the expert consensus on integrated traditional Chinese and Western medicine diagnosis and treatment of UC, the main symptoms are diarrhea, mucopurulent and bloody stool, abdominal pain, and tenesmus. Secondary symptoms: anal burning, body heat is not Yang, dry mouth and bitter mouth, short red urine. Tongue pulse: tongue red fur yellow greasy, pulse slippery number. The determination of the above 8 syndromes can be made if there are 2 main symptoms and 1-2 secondary symptoms. The tongue pulse is for reference only.

The patients are complicated with other diseases that may cause diarrhea, such as infectious colitis, radiation enteritis, Crohn's disease, etc.
Patients with heart, brain, lung, liver, kidney and other serious diseases;
