- Abstract: Objective To explore the intestinal barrier regulation effect of Butuyajie recipe on antibiotic-associated diarrhea rats.Methods 60 SD male rats were randomly divided into blank group,model group,positive drug group(1 g·kg-1),and high-dose,medium-dose and low-dose groups of Butuyajie recipe(40.5,20.25,10.125 g·kg-1).The model was replicated by intragastric administration of lincomycin hydrochloride(5 g·kg-1)for 7 consecutive days.After successful modeling,the materials were obtained after drug intervention for 7 days.Intestinal pathological morphology was observed by HE staining.ELISA kit to detect DAO,MPO,LPS.Take each organ tissue to detect bacterial translocation.Feces were collected for 16S rRNA gene high-throughput sequencing analysis.Results Compared with the normal group,the serum levels of DAO,MPO and LPS in the model group were significantly increased(P<0.001,P<0.01),and the sIgA content in the intestinal mucosa was significantly decreased(P<0.001).Promote intestinal bacterial translocation(P<0.001,P<0.01).The diversity of intestinal flora was significantly reduced,and the levels of intestinal microflora and genera were significantly changed.Butuyajie recipe can reduce the content of DAO,MPO and LPS(P<0.001,P<0.01,P<0.05),significantly increase the content of sIgA(P<0.01,P<0.05),and effectively inhibit the translocation of intestinal bacteria(P<0.001,P<0.01,P<0.05).At the same time,it corrects the intestinal microecological structure by increasing Firmicutes,inhibiting the proportion of Bacteroidetes and Proteobacteria,and regulating Lactobacillus,Sphingomonas,Pseudomonas,and Enterobacter.Conclusion Butuyajie recipe can reduce the permeability of intestinal mucosa,reduce the translocation of intestinal flora,protect the intestinal immune barrier,regulate the diversity of intestinal flora structure,improve the intestinal microecological disorder,and can effectively treat antibiotic-associated diarrhea.
