Abstract: 目的探讨2型糖尿病患者血清基质金属蛋白酶-8(MMP-8)水平与颈动脉粥样硬化的相关性。方法选择正常对照组(NC组)60例、糖尿病组(DM组)89例。糖尿病组根据颈动脉内-中膜厚度(IMT)及斑块情况分为糖尿病非颈动脉粥样硬化组(DM1组,n=16)和糖尿病合并颈动脉粥样硬化组(DM2组,n=73),比较三组的血清MMP-8水平;DM2组分为IMT增厚组(A组,n=12)、稳定斑块组(B组,n=27)和不稳定斑块组(C组,n=34),比较三个亚组的IMT、Crouse积分等超声指标,分析MMP-8水平与颈动脉超声指标的相关性。结果DM2组的MMP-8、IMT值水平高于NC组和DM1组,DM1组高于NC组(P均<0.05);不稳定斑块组的MMP-8水平高于稳定斑块组和IMT增厚组,稳定斑块组MMP-8水平高于IMT增厚组(P均<0.05);血清MMP-8水平与IMT值和Crouse积分呈正相关(r值分别为0.68、0.72,P<0.05)。结论血清MMP-8与2型糖尿病动脉粥样硬化斑块的形成和斑块稳定性相关,可作为预测颈动脉斑块形成及稳定与否的血清学指标。
