摘要 目的探讨多发性硬化(multiple sclerosis,MS)患者血清基质金属蛋白酶-9(matrix metallopmteinases-9,MMP-9)、金属蛋白酶组织抑制剂-1(tissue inhibit or ofmetalloproteinases-1,TIMP-1)水平及MMP-9/TIMP-1比值变化及与临床的关系。方法应用酶联免疫吸附法(enzynis-finked immunoadsonlent assay,ELISA)测定32例MS患者及20名健康对照组(health control,HC)血清MMP-9、TIMP-1水平,计算MMP-9/TIMP-1比值,并分别进行统计学分析。结果MS患者血清MMP-9水平及MMP-9/TIMP-1值较健康对照组显著升高,而TIMP-1水平则显著降低,参异均有统计学意义(P<0.01),MRI钆(galolinium,Gd)强化扫描阴性(Gd-)MS患者较钆强化扫描阳性(Gd+)MS患者血清MMP-9水平及MMP-9/TIMP-1值显著降低(P<0.01),但仍显著高于健康对照组(P<0.05),而TIMP-1水平则显著升高(P<0.01),同时仍显著低于健康对照组(P<0.05)。结论MMP-9、TIMP-1参与了MS的发病,MMP-9水平升高及TIMP-1水平降低与MS活动有关,MMP-9/TIMP-1比值可作为监测MS活动性的生物学指标。
