摘要 目的探讨人蛋白酶活化受体(PAR)-2在子痫前期患者胎盘组织中的表达及临床意义。方法选取2009年12月至2010年11月于吉林大学第二医院住院剖宫产分娩的子痫前期患者60例(轻度子痫前期组及重度子痫前期组各30例)和同期正常妊娠妇女30例(正常妊娠组),采用免疫组化方法检测各组胎盘组织中的PAR-2的表达,进行其灰度值分析(灰度值越大阳性越弱,灰度值越小阳性越强)。结果 PAR-2阳性表达的灰度值在轻、重度子痫前期组胎盘组织中明显低于正常妊娠组(P均<0.01);重度子痫前期组胎盘组织中PAR-2阳性表达的灰度值低于轻度子痫前期组(P<0.01)。结论胎盘组织中PAR-2表达升高与子痫前期的发病机制相关,且其表达水平可能与子痫前期的病情进展有关。
