摘　　要：目的:建立重症急性胰腺炎大鼠模型,研究生长抑素(奥曲肽)联合大柴胡汤对急性重症胰腺炎的作用及初步机制。方法:50只大鼠随机分为假手术组、模型组、奥曲肽组、大柴胡汤组与联合组,经相应处理后记录腹水量,测定血清中淀粉酶(amylase,AMY)、丙氨酸氨基转移酶(alanine aminotransferase,ALT)和肌酐(creatinine,Cr)的水平,HE染色后观察胰腺组织形态,Western blot检测胰腺细胞核中NF-κB与细胞中IκBα的蛋白表达水平,qPCR检测胰腺细胞中ICAM-1与IL-1的mRNA表达水平。结果:生长抑素联合大柴胡汤能有效降低重症急性胰腺炎大鼠的腹水量以及血清中AMY、ALT和Cr的水平;重症急性胰腺炎可导致胰腺细胞核NF-κB蛋白表达升高,IκBα蛋白表达降低,ICAM-1和IL-1 mRNA表达升高。生长抑素联合大柴胡汤可逆转这些改变。结论:生长抑素联合大柴胡汤可以减轻大鼠的急性重症胰腺炎,其机制可能与抑制NF-κB信号通路以及ICAM-1和IL-1表达有关。AIM： To investigate the combined effect of octreotide and Dachaihu decoction on the treatment of severe acute pancreatitis（ SAP）. METHODS： Wistar rats（ n = 50） were randomly divided into sham group,SAP group,octreotide group,Dachaihu decoction group and combination group. The quantity of ascites was measured. The levels of amylase,alanine aminotransferase and creatinine in the serum were examined. The morphological changes of the pancreatic tissues were observed by HE staining. The activation of NF-κB and IκBα expression were determined by Western blot. The mRNA expression with ICAM-1 and IL-1 was detected by qPCR. RESULTS： Combined treatment with octreotide and Dachaihu decoction effectively reduced the quantity of ascites and the levels of amylase,alanine aminotransferase and creatinine in the serum in SAP rats. Moreover,combined treatment significantly inhibited SAP-induced activation of NF-κB and decrease in IκBα protein expression,accompanied by a decrease in ICAM-1 and IL-1 mRNA expression. CONCLUSION： Combination of octreotide with Dachaihu decoction effectively attenuates SAP by inhibiting NF-κB signaling pathway and ICAM-1 and IL-1 expression.
