About

Traditional Chinese Medicine focuses on the main pathogenesis of liver depression and spleen deficiency, and treats them from the perspective of soothing the liver and strengthening the spleen to treat on Diarrhea-predominant irritable bowel syndrome (IBS-D) . The classic formula for treating is the Tong-Xie-Yao-Fang (TXYF). Based on metabolomics and metagenomics, the research group studied the intestinal flora and host co metabolism of TXYF in the treatment of diarrhea predominant IBS-D, in order to clarify the mechanism of TXYF in the treatment of IBS-D.

Full description

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a common clinical functional gastrointestinal disease with unclear mechanism, which is mostly induced by emotion. There is no specific treatment for this disease. Traditional Chinese Medicine focuses on the main pathogenesis of liver depression and spleen deficiency, and treats them from the perspective of soothing the liver and strengthening the spleen. The classic formula for treating is the Tong-Xie-Yao-Fang (TXYF).Previous studies of our research group have shown that TXYF can significantly improve the symptoms of abdominal pain and diarrhea in patients with IBS-D, and improve the quality of life of patients. The effectiveness and safety of TXYF in the treatment of IBS-D have been evaluated, and its mechanism of action has also been explored.Modern studies have shown that changes in the local immune microenvironment can affect intestinal immunity and neuroregulation, mucosal barrier damage and abnormal co-metabolism of flora and host, which may be important reasons for the occurrence and development of IBS-D, but the detailed mechanism is unclear.Therefore, based on metabolomics and metagenomics, the research group studied the intestinal flora and host co metabolism of TXYF in the treatment of diarrhea predominant IBS-D, in order to clarify the mechanism of TXYF in the treatment of IBS-D.
