摘要 目的研究新生儿缺氧缺血性脑病(hypoxic ischemic encephalopathy HIE)患儿血清中金属蛋白酶-9(matrix metalloproteinase-9MMP-9)、NO(nitric oxide)水平的动态变化,探讨金属蛋白酶-9、NO水平和新生儿脑缺氧缺血后脑损伤程度之间的关系。方法选用HIE患者40例,采用酶联免疫吸附法(ELISA法)及硝酸还原法测定其发病后1d、3d、7d血清MMP-9、NO浓度,与健康对照组比较。结果 HIE患者血清MMP-9、NO水平与对照组水平比较均升高,差异有统计学意义(P<0.05),以发病3d水平升高尤著,此后呈降低趋势。重度HIE患者发病后3d血清MMP-9水平高于中、轻度组(F=5.119,P<0.05),3组之间比较差异均有统计学意义。结论 HIE患者血清MMP-9、NO水平升高,提示MMP-9、NO可能参与了HIE的发病机制。程度越重,血清MMP-9、NO升高越明显。血清MMP-9、NO水平变化和脑损伤程度有关,可能对病情的严重程度和预后有预示作用。
