摘要 目的探讨基质金属蛋白酶9(MMP-9)及其抑制物TIMP-1在子宫内膜异位症发病中的作用.方法选择2000年9月至2001年9月在南方医科大学珠江医院妇产科确诊为子宫内膜异位症者30例,同期非子宫内膜异位症20例.采用RT-PCR技术检测子宫内膜异位症(内异症)异位和在位内膜及非内异症病人子宫内膜中MMP-9及TIMP-1的表达,凝胶图像光密度分析系统进行PCR产物电泳条带扫描分析.结果异位内膜MMP-9 mRNA、MMP-9/TIMP-1比值显著高于在位内膜及非内异症子宫内膜(P<0.01),而TIMP-1 mRNA的表达则显著低于后两者(P<0.01).从美国生育协会修正分期标准(rAFS)Ⅰ~Ⅳ期,异位病灶MMP-9 mRNA的表达呈上升趋势,TIMP-1mRNA表达则呈下降趋势.结论异位病灶MMP-9的高水平表达,提示异位内膜组织具有较高的蛋白水解活性,使其具有更强的侵袭能力,易于发生种植转移,可能在子宫内膜异位症的发生发展过程中发挥重要作用.
