The Role of Intestinal Flora in the Pathogenesis of FD and the Intervention of Xiangsha Liujunzi

Functional dyspepsia (FD) is a common digestive system disease in clinic. Although it has not reached the level of life-threatening, it seriously affects the quality of life of patients. The pathogenesis of FD mainly involves gastric motility disorder and visceral hypersensitivity. At present, there are gastric motility promoting drugs and gastric acid inhibiting drugs, but they can not achieve satisfactory therapeutic effect. Traditional Chinese medicine has a good clinical effect on FD, but the specific mechanism is not clear. With the gradual deepening of intestinal flora research, it provides a useful tool for elucidating the mechanism of action of traditional Chinese medicine compound. The role of intestinal flora in the pathogenesis of FD, especially in the pathogenesis of symptoms, has not been studied, and the mechanism of Spleen-strengthening and motility-promoting effects of Xiangsha Liujun has not been studied from the perspective of intestinal flora. In this study, 16S rRNA high-throughput sequencing technology was used to observe the difference of intestinal flora between FD patients and normal people, and then to observe the effect of Xiangsha Liujun on intestinal flora of FD patients. The aim of this study was to explore the role of intestinal flora in the pathogenesis of FD and to elucidate the therapeutic mechanism of Xiangsha Liujunzi by regulating intestinal flora of FD patients, so as to provide support for follow-up clinical and experimental studies.
