摘要
目的基质金属蛋白酶-10(MMP-10)与动脉粥样硬化有着密切关系, 且近期研究发现, MMP-10的血清水平在急性脑梗死鼠模型的梗死组织中有所升高, 但是对于急性脑梗死患者的MMP-10血清水平至今尚无相关研究。我们研究了急性脑梗死患者MMP-10水平的变化及其与急性缺血性脑卒中试验病因分型、病情严重程度、危险因素和颈动脉斑块之间的关系。方法选择2012年4–12月在我院神经内科住院的109例急性脑梗死患者作为病例组, 另选85名健康体检者作为对照组。取病例组和对照组外周血, 测定MMP-10血清水平, 并搜集入组患者资料进行分组及统计学分析。结果急性脑梗死病例组MMP-10血清水平明显高于对照组[分别为6.59 (6.07, 7.31) μg/L、5.16 (3.87, 5.94) μg/L, Z=8.33, P<0.01];NIHSS评分与MMP-10之间呈正相关(r=0.204, P=0.037);根据危险因素分组, 血脂异常组较血脂正常组MMP-10血清水平升高(Z=2.07, P=0.042);MMP-10与低密度脂蛋白(LDL)-胆固醇水平呈正相关(r=0.248, P=0.040), 而与凝血酶激活的纤溶抑制物(TAFI)呈负相关(r=–0.208, P=0.030);病例组中, 不稳定性斑块组MMP-10血清水平较稳定性斑块组升高, 且两组间的差异具有统计学意义[分别为6.62 (6.13, 7.36) μg/L、6.10(6.00, 6.46) μg/L, Z=2.12, P=0.034]。结论急性脑梗死患者体内MMP-10血清水平较健康人群显著升高, 且病情越严重, MMP-10血清水平升高越明显。血脂异常组的MMP-10血清水平高于血脂正常组, 且MMP-10血清水平与LDL-胆固醇水平呈正相关, 与TAFI水平呈负相关, 提示MMP-10可能与动脉粥样硬化的发生发展密切相关。MMP-10血清水平可能与不稳定性斑块的形成及破裂有关, 在急性血栓形成的机制中意义深远。
