摘要 目的:探讨基质金属蛋白酶(MMP)-9和基质金属蛋白酶抑制剂(TIMP)-3的表达与早期自然流产的关系。方法:于手术时收集30例自然流产孕妇及20例要求行人工流产的正常早孕孕妇的绒毛组织,分为自然流产组及正常绒毛组,提取绒毛组织总RNA,应用RT-PCR法检测其中MMP-9 mRNA和TIMP-3 mRNA的表达水平,计算MMP-9 mRNA/TIMP-3 mRNA。结果:自然流产组的MMP-9 mRNA、TIMP-3 mRNA的相对表达量分别为0.35~0.74(0.55)、0.80~1.00(0.90),其MMP-9 mRNA/TIMP-3 mRNA比值为0.35~0.80(0.54),正常绒毛组的MMP-9 mRNA及TIMP-3mRNA的相对表达量分别为0.11~0.39(0.25)、0.76~0.99(0.87),其MMP-9 mRNA/TIMP-3 mRNA比值为0.11~0.30(0.19),自然流产组的MMP-9 mRNA表达水平、MMP-9 mRNA/TIMP-3 mRNA比值明显高于对照组(均为P<0.01),两组TIMP-3 mRNA水平相近(P>0.05)。结论:自然流产者的MMP-9 mRNA表达水平较高,其MMP-9 mRNA/TIMP-3 mRNA比值亦较高,MMP-9 mRNA表达水平及MMP-9 mRNA/TIMP-3 mRNA的比值与自然流产可能有关。
