摘要(Abstract)：

目的探讨冠心病患者血浆巨噬细胞游走抑制因子(MIF)水平和外周血白细胞激活蛋白-1(AP-1)表达量与冠状动脉粥样硬化病变的关系。方法根据冠状动脉造影结果将142例患者分为冠心病组和对照组,冠心病组根据临床类型分为稳定型心绞痛(SAP)亚组和急性冠状动脉综合征(ACS)亚组,根据冠状动脉病变类型分为A型病变亚组、B型病变亚组和C型病变亚组,根据冠状动脉病变程度分为轻度病变亚组、中度病变亚组和重度病变亚组。通过ELISA法测定外周血白细胞裂解液中磷酸化c-Jun吸光度,反映活化AP-1的数量。血浆MIF通过ELISA法测定。结果冠心病组磷酸化c-Jun表达量明显高于对照组(1.43±0.33比0.71±0.13,P<0.01),MIF水平明显高于对照组(14.97±4.11 ng/mL比9.07±1.28 ng/mL,P<0.01)。冠心病组中,ACS亚组磷酸化c-Jun表达量明显高于SAP亚组(1.56±0.28比1.14±0.25,P<0.01),MIF水平明显高于SAP亚组(16.66±3.56 ng/mL比11.01±2.12 ng/mL,P<0.01)。磷酸化c-Jun表达量和MIF浓度随冠状动脉病变类型和冠状动脉病变程度的加重而逐渐升高。结论AP-1和MIF与冠状动脉粥样硬化发生及冠状动脉病变情况显著相关,其可能作为预测冠状动脉粥样硬化病变情况及斑块稳定性的一个指标。AP-1表达量与MIF浓度越高,斑块不稳定性越高。
