Abstract: OBJECTIVE: To evaluate the efficacy of the extract from Ganjiangdazao recipe(EGR) on functional dyspepsia in rats with spleen-stomach deficiency cold pattern(SSDCP) in terms of Traditional Chinese Medicine, and to investigate its pharmacodynamics.METHODS: Sixty Sprague-Dawley rats were randomly divided into the control group, SSDCP group, low-EGR SSDCP group, high-EGR SSDCP group, probiotics group, EGR group. SSDCP model was induced by gavage with the 0 ℃ edible vinegar. The symptoms and manifestations were scored by method from the relative literature, the ecological changes in cecal microflora was analyzed by16 SrRNA high-throughput sequencing technology,gastric tissues were treated by immunohistochemistry, the levels of related biochemical components related to the gastrointestinal functions were detected by enzyme-linked immunosorbent assay and colorimetry, gastric juice was measured by pH meter, blood pressure measurement by trapping tail method, surface temperature measured by infrared thermal imaging, and the content of 6-gingerol in the serum was determined by liquid-mass chromatography before and after EGR was given.RESULTS: It was found that EGR could effectively relieve the symptoms and manifestations of the SSDCP rats(P < 0.05); the value of the relative abundance of Lactobacillus, Streptococcus, Enterococcus and Coprobacillus increased, while the value of the relative abundance of Clostridium decreased(P < 0.05) in the cecal microflora in the SSDCP rats after high-EGR administration; It was also found that EGR had no substantial effect on the related biochemical components related to the gastrointestinal functions of in the SSDCP rats; and a certain amount of 6-gingerol was detected in the serum of EGR group.CONCLUSION: The pharmacodynamic site of EGR is the intestinal tract, and the mechanism behind the effect of EGR on SSDCP rats, involves increasing the beneficial bacteria and decreasing the proinflammatory bacteria in the intestinal tract. The blood pharmacodynamics of EGR remains to be further studied in the future.
