Exploration on the Effects of Huosha Oral Liquid on Intestinal Mucosal Barrier in IBS-D Cold and Dampness Syndrome Rats Based on Notch1/Hes-1/Math-1 Signaling Pathway
摘要
Abstract
Objective To observe the effects of Huosha Oral Liquid on irritable bowel syndrome with diarrhea(IBS-D)rats with cold and dampness syndrome based on Notch1/Hes-1/Math-1 signaling pathway;To elucidate its mechanism of repair of intestinal mucosal barrier.Methods An IBS-D cold and dampness syndrome rat model was established by using restraint stress combined with bitter-cold cathartic method and cold and dampness environmental method.After modeling,the rats were randomly divided into model group,Western medicine group and Huosha Oral Liquid low-,medium-and high-dosage groups,with 6 rats in each group.An additional 6 rats were set as the normal group.The Western medicine group was given mebeverine(13.5 mg/kg)by gavage,while the Huosha Oral Liquid low-,medium-and high-dosage groups were given Huosha Oral Liquid(3.15,6.3,12.6 g/kg)by gavage,the normal group and model group were given distilled water by gavage,for 4 weeks.The general status of rats were ovserved,the body mass,loose stool rate,fecal water rate and abdominal withdrawal reflex(AWR)score were measured,the morphalogy of colon tissue were observed by HE staining,the mRNA expression of Occludin,ZO-1,Notch1,Hes-1 and Math-1 in colon tissue were detected by RT-PCR,the protein expression of Notch1 was detected by Western blot.Results Compared with the normal group,the model group had a reduced body mass(P<0.05)and increased loose stool rate,fecal water rate and AWR score(P<0.05),inflammatory cell infiltration was observed in colon tissue and the expressions of Occludin,ZO-1,Math-1 mRNA decreased(P<0.05),the expressions of Notch1,Hes-1 mRNA increased(P<0.05),and the expression of Notch1 protein increased(P<0.05).Compared with the model group,the body mass of rats in Western medicine group and Huosha Oral Liquid low-,medium-and high-dosage groups increased(P<0.05),loose stool rate,fecal water rate and AWR scores decreased(P<0.05),a small amount of neutrophils was visible in the colon tissue,the expressions of Occludin,ZO-1,Math-1 mRNA in colon tissue increased in Huosha Oral Liquid medium-and high-dosage groups(P<0.05)and the expressions of Notch1 and Hes-1 mRNA decreased(P<0.05),the expression of Notch1 protein decreased in Western medicine group and Huosha Oral Liquid groups(P<0.05).Conclusion Huosha Oral Liquid may regulate the expressions of tight junction proteins by inhibiting excessive activation of the Notch/Hes-1/Math-1 signaling pathway,thereby protecting the intestinal mucosal barrier function,improving diarrhea symptoms in IBS-D rats with cold and dampness syndrome,and reducing visceral sensitivity and colonic tissue inflammation.关键词
