Abstract： 目的 探讨基质金属蛋白酶(MMP)2、9在子痫前期患者胎盘绒毛中的表达及其与子痫前期发病的关系.方法 采用免疫组化链霉亲和素-生物素-过氧化物酶复合物(SABC)法检测20例子痫前期患者(病例组)和20例正常孕妇(对照组)胎盘绒毛MMP-2、9的表达,实时荧光定量RT-PCR检测两组孕妇胎盘绒毛MMP-2、9 mRNA的表达水平.因提取后的mRNA部分降解,用于RT-PCR检测的胎盘绒毛病例组13份,对照组10份.采用2-△△Ct相对定量表示PCR结果.结果 对照组孕妇胎盘绒毛MMP-2、9的染色强度均高于病例组,两组比较,差异有统计学意义(P＜0.05);对照组胎盘绒毛MMP-2 mRNA的平均表达水平为7.6±2.8,病例组胎盘绒毛MMP-2 mRNA的平均表达水平为5.6±1.5,两组比较,差异有统计学意义(P＜0.05).对照组胎盘绒毛MMP-9 mRNA的平均表达水平为2.2±2.6,高于病例组的-0.9±2.0,两组比较,差异也有统计学意义(P＜0.05).对照组胎盘绒毛MMP-2的平均表达水平高于MMP-9,两者比较,差异有统计学意义(P＜0.05).结论 MMP-2、9表达降低导致的滋养细胞侵袭能力的下降,可能与子痫前期的发病相关.
