摘　　要：目的:检测白细胞介素10(IL-10)与整合素家族细胞黏附分子LFA-1、Mac-1在急性坏死性胰腺炎(ANP)合并多器官损伤大鼠模型中表达的动态变化。方法:应用ELISA法连续测定大鼠ANP合并多器官损伤模型血清IL-10的变化。应用流式细胞仪,于多个时相点检测整合素家族细胞黏附分子LFA-1、Mac-1在ANP合并多器官损伤SD大鼠血中性粒细胞表面表达的变化,并检测血浆淀粉酶及胰腺、肺和肾脏的病理学损害。结果:IL-10、LFA-1和Mac-1在ANP组中各个时相点的表达均明显高于对照组(P<0.05或P<0.01)。ANP组中血浆淀粉酶明显高于对照组,并有明显的胰腺、肺和肾脏的病理学改变。结论:IL-10和整合素家族细胞黏附分子LFA-1、Mac-1均参与了ANP继发多器官功能损伤的过程。Objective To detect the expression of IL-10 and integrin family cellular adhesion molecules LFA-1 and Mac-1 in rats with acute necrotizing pancreatitis complicated with multiple organ injury. Methods LFA-1 and Mac-1 expression of leukocyte was detected with flow cytometer and IL-10 was detected with ELISA in rats with acute necrotizing pancreatitis at different time points. Results The expression of IL-10, LFA-1 and Mac-1 increased significantly in acute pancreatitis group than that in control group at all time points （P 〈 0.05 or P 〈 0.01）. Morphological examination demonstrated that inflammatory cell, insterstitial edema, interstitial hemorrhage, desquamate and disintegration occurred in lungs and kidney. Conclusion IL-10, LFA-1 and Mac-1 may play an important role in the development of acute pancreatitis.
