Abstract

目的 了解病毒性脑炎患儿脑脊液中水通道蛋白4(AQP4)、基质金属蛋白酶-9(MMP-9)及神经元特异性烯醇化酶(NSE)的水平变化的意义。 方法 观察2012年1月至2014年12月在新乡医学院第三附属医院神经内科、儿科住院治疗的病毒性脑炎患儿40例,分为轻症组(20例)和重症组(20例),并设置同期住院的非中枢神经系统感染患儿14例为对照组,3组患儿均经ELISA法检测脑脊液AQP4、MMP-9及NSE的水平。 结果 轻症组和重症组病毒性脑炎患儿脑脊液AQP4水平分别为(13.914±4.146) ng/L和(39.983±14.252) ng/L,2组脑脊液MMP-9水平分别为(19.650±4.479) μg/L和(85.756±21.394) μg/L,NSE分别为(27.514±7.893) mg/L和(68.921±17.452) mg/L。轻症组和重症组的AQP4、MMP-9及NSE水平均较对照组患儿明显升高,差异均有统计学意义(P均<0.05),且重症组患儿较轻症组患儿脑脊液水平明显升高,差异均有统计学意义(P均<0.05)。 结论 脑脊液AQP4、MMP-9及NSE可作为临床早期判断病毒性脑炎患儿病情严重程度的实验室指标之一。
