清肠化湿方对TNBS大鼠结肠组织PPAR-γ/p38 MAPK的影响
Effects of Qingchang Huashi Decoction on Expression of PPAR-γ and p38 MAPK in Colonic Mucosa of Rats with Ulcerative Colitis
摘要
Abstract
Objective:To investigate the efficacy of Qingchang Huashi decoction (QHD ) on ulcerative colitis induced by 2 , 4 , 6- trinitrobenzen sulfonic acid ( TNBS ) in Wistar rats and determine the expression of PPAR-γ and p38 MAPK in colonic mucosa of rats in further to study the function and mechanism of QHD in rats with ulcerative colitis. Methods:Eighty male Wistar rats were used to establish UC models and di-vided randomly into eight groups:the normal group,model group,QHD-low group,QHD-medium group, QHD-high group,SASP group,SASP+BADGE group and the QHD-medium+BADGE group. Each group had ten rats. TNBS was used in seven groups except for the normal group to establish ulcerative colitis model in rats. SASP and BADGE which were the inhibitors of PPAR-γ were used. After 7 days,the colonic pathological morphology was observed. Western blot and Real-time PCR(RT-PCR) were performed to detect the protein levels and mRNA levels of PPAR-γ and p38 MAPK. The expressions of MUC2 and TFF3 in colonic mucosa were also measured by RT-PCR. Results:Compared with the model group,QHD could effec-tively improve the life quality,reduce colon tissue inflammatory cells infiltration,enhance colonic mucosal tissue repair and promote the recovery of UC rats. QHD could increase PPAR-γ expression and inhibit p38 MAPK activity. In addition,QHD was able to increase significantly the expressions of MUC2 and TFF3 in colonic mucosa. Conclusion:QHD had ob-vious protective effect on UC. One of the mecha-nisms might be that QHD could active PPAR-γsignaling and inhibit p38MAPK activation,increase the expression of MUC2 and TFF3 in colonic tissue to participate in restoration of intestinal mucosa ,and inhibit the release of inflammatory cells.关键词
