Study on the Rule and Mechanism of Treating Functional Gastrointestinal Diseases From the Perspective of Liver and Spleen

Major Achievements in Traditional Chinese Medicine Science and Technology Guidance Projects-Study on the Rule and Mechanism of Treating Functional Gastrointestinal Diseases

To clarify the changes of intestinal flora - gut - brain axis in FGIDs patients represented by NERD disharmony of liver and stomach and IBS-D disharmony of liver and spleen, and confirm that the imbalance between intestinal flora and host co-metabolism is the key to the pathogenesis of functional gastrointestinal disease. To reveal the common mechanism of regulating liver and spleen (stomach) in treating FGIDs dynamic disorder and visceral hypersensitivity by regulating intestinal flora - intestine - brain axis disorder.
