简要总结
Diarrhea-predominant irritable boewl syndrome(IBS-D) seriously affect the quality of life in patients. Clinically, it is effective to apply therapeutic method of clearing heat and promoting diuresis to the common syndrome of dampness-heat. Dysbiosis of intestinal microbiota is closely related to the immune imbalance and intestinal mucosal barrier injury. C1orf106/CYTH-1/ARF6 signal pathway, which derive from intestinal micro environment changes,is the mainly cause of intestinal mucosal barrier injury, and this is may be the common pathogenesis of dampness-heat syndrome in IBS-D . Based on the clinic, the project is to study the effect and mechanism of Chinese compound formula of clearing heat and promoting dieresis in modulating intestinal microbiota dysbiosis, repairing intestinal mucosal barrier and reconstructing intestinal microenvironment. With the combination of metagenomics and metabonomics, the study compare the differences of co-metabolites of intestinal microbiota and host within the healthy people, IBS-D patients with dampness-heat syndrome, to explore the relevance between intestinal flora and host co-metabolites. Furthermore, the experimental study is to clarify the drug targets via C1orf106/ CYTH-1/ARF6 signal pathway.Through the study of association between dampness-heat syndrome in IBS-D and intestinal microbiota, it is of important academic significance to reveal the Chinese theory intension of "homotherapy for heteropathy ".

结局指标
主要结局
IBS symptom severity (IBS-SSS)scale
时间窗: Change from Baseline disease activity at 4weeks
The IBS-SSS scale is scored from five aspects: the degree of abdominal pain, the frequency of abdominal pain, the degree of bloating, the degree of defecation satisfaction, and the impact on life.Each score is 0-100 points, and the total score is IBS-SSS scores from the degree of abdominal pain, the frequency of abdominal pain, the degree of abdominal distention, the satisfaction of defecation and the impact on life. Each score is 0-100, and the total score is 0-500. The higher the score, the more serious the disease is.
