Objective:Jianpi huoxue decoction(JHD),a Chinese herbal formula,is commonly used for treating alcohol-associated liver disease(ALD).This study aimed to investigate the mechanism by which JHD affects intestinal barrier function in ALD rats.Methods:The Sprague-Dawley rats were randomly divided into three groups:control group,model group and JHD group.They were pair-fed a modified Lieber-DeCarli liquid diet containing alcohol(model group,n=10;JHD group,n=10)or isocaloric maltose dextrin(control group,n=10)for 6 weeks.After 3 weeks of feeding,the mice in the JHD group were given JHD(10 mL/kg/day)by gavage for 3 weeks,and those in the control and model groups received equal amounts of double-distilled water for the same period of time.Afterwards,all the rats were given lipopolysaccharide(LPS)by gavage and sacrificed 3.5 h later.LPS levels were measured in the portal blood to evaluate gut leakage.Transmission electron microscopy(TEM)was used to observe ultrastructural changes in the intestinal tract.Adherens junction(AJ)and tight junction(TJ)proteins were detected by Western blotting,immunofluorescence or immunohistochemistry.Results:JHD ameliorated Lieber-DeCarli liquid diet-induced hepatic steatosis,inflammation and LPS expression.It improved pathological changes in the liver and alleviated intestinal ultrastructure injury.Moreover,it significantly enhanced the integrity of tight junctions by increasing the expression of zonula occludens-1(ZO-1)and occludin.It suppressed the activation of myosin light chain(MLC)phosphorylation.Conclusion:JHD improves intestinal barrier function and reduces gut leakiness in ALD rats.
