Abstract： 目的探讨单核细胞趋化蛋白(MCP-1/JE)在重症急性胰腺炎(severe acute pancreatitis, SAP)发病机制中的作用.方法以5%牛磺胆酸钠逆行胆胰管注射制作大鼠SAP模型,检测胰腺湿/干重比和进行胰腺组织病理学评价,分别采用逆转录-聚合酶链反应(RT-PCR)和免疫组织化学方法,检测胰腺组织中MCP-1/JE mRNA及蛋白的表达.结果与假手术组相比,造模各组胰腺湿/干重比在12 h内明显上升(P ＜ 0.01),假手术组无MCP-1/JE蛋白的表达,SAP组胰腺腺泡细胞有阳性表达,胰腺组织内MCP-1/JE mRNA的表达显著上调(P ＜ 0.05或P ＜ 0.01),并且与胰腺湿/干重比及胰腺组织损害程度呈正相关.结论 MCP-1/JE在SAP早期发病中可能起重要作用.
