Objective:To explore the effects of Jianpi Mixture on the glucose receptor/glucagon like peptide-1 (GLP-1)/5-hydroxytryptamine (5-HT) signaling pathway and the mechanism of Jianpi Mixture in improving visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome (IBS-D) rats.Methods:Totally 40 healthy male SPF rats were divided into blank group, model group, Jianpi Mixture low- and high-dosage groups according to the random number table method, with 10 rats in each group. Except for the blank group, the rest of the rats were prepared by the "senna gavage combined with restraint stress" method to replicate the IBS-D spleen deficiency model. The aqueous extract of Jianpi Mixture was 2.52 and 7.56 g/kg in the low- and high-dosage groups, and the same volume of normal saline was given to the blank group and the model group, once a day, for 14 days. On the 1st, 7th and 14th days of administration, the body weight of rats was recorded, the fecal traits of the rats were scored with Bristol score, the visceral sensitivity of IBS-D rats was evaluated by the abdominal wall retraction reflex score (AWR) under rectal dilation, the morphology of colonic mucosal tissues was observed by HE staining, and the protein expressions of T1R2, SLGT1, GLUT2, GLP-1 and 5-HT in colon tissues were detected by immunohistochemical staining.Results:On the 1st, 7th and 14th days of administration, compared with the model group, the weight of the rats in the Jianpi Mixture high-dosage group increased ( P<0.05); on the 14th day of administration, the fecal Bristol score decreased significantly ( P<0.05) and the AWR score increased ( P<0.05); HE staining showed that the mucosal epithelium of colon tissue in the model group was slightly damaged, and local edema was visible. The pathological condition of colonic mucosa in the Jianpi Mixture low- and high-dosage groups was effectively improved; compared with the model group, the expressions of T1R2 and GLP-1 in the Jianpi Mixture low- and high-dosage groups increased ( P<0.05), and the expression of 5-HT decreased ( P<0.05); the protein expressions of GLUT2 and SGLT1 in the Jianpi Mixture high-dosage group increased ( P<0.05). Conclusion:Jianpi Mixture can treat spleen-deficiency IBS-D by restoring the normal expression of intestinal glucose receptors, regulating the secretion of GLP-1/5-HT, improving intestinal motility and alleviating visceral hypersensitivity.

The intestinal flora and gut barrier function are of great significance for gut function and human health. When the intestinal flora is disrupted and the gut barrier structure is disrupted, it can lead to bacterial translocation, endotoxin influx into the bloodstream, and the production of pro-inflammatory factors, leading to various tissue damage in the body. Tongfu method in TCM can affect the intestinal environment by regulating intestinal permeability and immune response, restoring normal intestinal movement, and regulating the structure and metabolites of intestinal flora, thereby maintaining intestinal homeostasis and body health. The research on regulating intestinal flora and improving intestinal barrier function by Tongfu method can provide reference for further research on the relationship between TCM and intestinal microecology, and provide ideas for clinical treatment.

Objective To investigate the correlation between ADAM33 T1, S2 gene polymorphism and Bronchial asthma risk in china. Methods We retrived the relevant published studies about ADAM33 T1, S2 gene polymorphism and bronchial asthma risk. Then we divided the population into Chinese and other Asian population. Odds ratio (OR) of Case group and control group was selected as the effect index. Stata 11.0 software was used to calculate heterogeneity test, ORs and 95%CI of two areas, and gave the forest plot and funnel plot of meta results. Results A total of 27 studies were included in this analysis,18 studies in ADAM33 T1 site were 3881 cases in case group, and 3780 cases in control group;and 14 studies in ADAM33 S2 site were 3222 cases in case group, and 3513 cases in control group. Additive model, dominant model, recessive model of ADAM33 T1 in Chinese had association with the susceptibility of bronchial asthma. The results were OR=1.488, 95% CI:1.002-2.167 in Additive model, OR=1.619, 95%CI:1.059-2.475 in dominant model;OR=2.523, 95%CI:1.910-3.333 in recessive model. Three models of ADAM33 T1 in other Asian country had no association with the susceptibility of Bronchial Asthma. Three gene model of ADAM33 S2 in Asian had no association with bronchial asthma susceptibility. Except ADAM33 T1 polymorphism in recessive model, other mode of T1, S2 had no publication bias in Chinese population. Conclusion There are association between ADAM33 T1 gene polymorphism and bronchial asthma, but ADAM33 S2 gene polymorphism and bronchial asthma have no association in Chinese population.
