摘要
目的:探讨生长抑素对大鼠重症急性胰腺炎(SAP)时炎性调控作用及其机制。方法:逆行胰胆管注射牛磺胆酸钠(TAC)制备SAP模型。动物分为假手术组(SO组),生理盐水处理组(SAP组)和奥曲肽治疗组。各组动物术后3、6、12 h剖杀,检测肝组织中Toll-样受体(TLR)24 mRNA和细胞核转录因子(NF-κB)的表达情况。结果:与SO组比较,胰腺炎组大鼠TLR2,4 mRNA于3 h开始升高,于12 h达高峰(P均<0.01);肝组织中NF-κB于3 h开始表达增强,6 h达高峰。治疗组肝组织中的TLR2,4 mRNA及NF-κB各时点表达均降低(P<0.05)。结论:生长抑素对SAP时炎症反应有调控作用。其机制可能与抑制Toll受体和NF-κB表达,降低瀑链式炎症反应有关。
Objective:To observe the effects and mechanisms of somatostatin on the control of inflammation in severe acute pancreatitis. Method:SAP model of rats was made with retrograde injection of artificial bile into the biliary-pancreatic duct. The rats were divided into control group and treating group which received injection of saline or Octreotide. Expressions of TLR2,TLR4 and NF-kB in the liver tissue were detected. Result:TLR2,4 mRNA in liver:in the SAP rised at 3 h,peaked at 12h( P均〈0.01);NF-kB expression in liver also rise at 3 h,but peaked at 6h. Treated with Somatostatin, the TLR2,4 mRNA and NF-kB expression in the liver decreased( P〈0.05). Conclusion:Somatostatin may inhibit the effects of the elastase and decrease TLR2,TLR4 mRNA and NF- kB expression.
