摘要 目的 研究基质金属蛋白酶-9(matrix metalloproteinases-9,MMP-9)和金属蛋白酶组织抑制因子-1(tissue inhibitor of metalloproteinases-1,TIMP-1)在重度子痫前期患者胎盘中的表达及临床意义.方法 选择2010年8月至2011年2月在西京医院妇产科住院分娩的孕妇60例,其中重度子痫前期组30例、正常妊娠(对照)组30例,采用免疫组化法、蛋白印迹法检测重度子痫前期患者和正常妊娠妇女胎盘滋养细胞中MMP-9、TIMP-1的表达.结果 在重度子痫前期组胎盘滋养细胞中,MMP-9的表达比正常胎盘滋养细胞中显著下降(0.04±0.01vs 0.12±0.03,t=5.70,P〈0.01),TIMP-1的表达则比正常胎盘滋养细胞中显著升高(0.10±0.01vs 0.02±0.003,t=4.42,P〈0.01),且MMP-9 /TIMP-1的比值明显低于在正常妊娠胎盘中的表达(0.40±0.12 vs 8.11±2.88,t=3.30,P〈0.01).结论重度子痫前期患者胎盘组织中MMP-9、TIMP-1的异常表达可能与滋养细胞侵入障碍相关.
