血清基质金属蛋白酶-9与2型糖尿病颈动脉粥样硬化的关系

目的 探讨血清基质金属蛋白酶-9(MMP-9)与2型糖尿病(T2DM)患者颈动脉粥样硬化的关系.方法 选择93例T2DM患者作为研究对象,测量患者颈动脉内中膜厚度(IMT)、斑块情况.根据IMT值将选取T2DM患者分为3组:单纯糖尿病组32例(糖尿病组),糖尿病颈动脉内中膜增厚组31例(中膜增厚组),糖尿病颈动脉粥样硬化斑块形成组30例(斑块组);另选健康查体者30名作为对照组.测定血清MMP-9浓度并进行相关分析.结果 糖尿病组血清MMP-9为(550.26±269.28)μg/L,显著高于对照组(359.70±215.62)μg/L,差异有统计学意义(t=2.23,P＜0.05);中膜增厚组MMP-9为(712.15±340.47)μg/L明显高于对照组(t=4.53,P＜0.01)和单纯糖尿病组(t=2.40,P＜0.05);斑块组MMP-9为(889.08±247.80)μg/L明显高于对照组(t=7.01,P＜0.01)、糖尿病组(t=4.89,P＜0.01)和中膜增厚组(t=2.53,P＜0.05).结论 血清MMP-9升高与颈动脉粥样硬化的病变程度密切相关.

Abstract：

Objective To investigated the relationship between serum matrix metalloproteinase-9(MMP-9) and carotid atherosclerosis(AS) in type 2 diabetes mellitus(T2DM).Methods A total of 93 patients with T2DM were recruited to our study.The intima-media thickness(IMT) and plaques of carotid artery were measured.These patients were divided into 3 groups according to their IMT values: diabetes mellitus(DM) group(n=32),carotid artery intima thicken group(n=31) and carotid artery intima plaque group(n=30).At the same time,30 healthy individuals were selected as control.Serum level of MMP-9 were determined and analyzed.Results The serum MMP-9 in DM group was significantly higher than that in healthy controls(550.26±269.28]μg/L vs.359.70±215.62]μg/L,t=2.23,P＜0.05).The serum MMP-9 level of intima thicken group(712.15±340.47)μg/L was significantly higher than that in healthy controls(t=4.53,P＜0.01) and DM group(t=2.40,P＜0.05).The serum MMP-9 level of plaque group(889.08±247.80]μg/L) was even more significantly higher than DM group(t=4.89,P＜0.01),IMT group(t=2.53,P＜0.05) and healthy controls(t=7.01,P＜0.01).Conclusion The severity of carotid atherosclerosis in T2DM is closely associated with the serum MMP-9 level.
