Regulatory Effect of Qing Yi Tang on Inflammatory Response in Rats with Acute Pancreatitis and Endotoxemia / 中华医院感染学杂志

ABSTRACT

OBJECTIVE To study the effect of Qing Yi Tang on acute pancreatitis(AP),especially AP complicated with endotoxemia and its possible mechanism.METHODS Fourty Wistar rats were divided into 5 groups including group A(the control group),group B(the AP group),group C(the AP group treated with Qing Yi Tang),group D(the AP group treated with LPS) and group E(the AP group treated with LPS + Qing Yi Tang).Pathological damage of pancreatic tissue was scored with HE staining.The mRNA expression of TNF-? was measured with semi-quantitative RT-PCR,and activation of NF-?B was detected with flow cytometry(FCM) assay.RESULTS It was shown in results that the expression of TNF-? mRNA,activation of NF-?B and pathological damage of the group B were all obviously higher than those of the group A.After treated with LPS which might promote the activation of NF-?B,there was seen the further rise of the activation of NF-?B,expression of TNF-? mRNA and pathological damage.When Qing Yi Tang intervention was applied,the activation of NF-?B and the expression of TNF-? mRNA could be remarkably relieved,so did the pathological damage of pancreas.CONCLUSIONS Qing Yi Tang may be applied to decrease activation of NF-?B and the expression of TNF-? so as to treat AP or AP with endotoxemia.
