Abstract

目的 探讨基质金属蛋白酶9(MMP-9)及其组织抑制剂1(TTMP-1)在子宫内膜异位症(内异症)患者异位内膜及在位内膜中的表达,及其在内异症发病中的作用.方法选取38例根据美国生育学会修订的内异症分期法,诊断为内异症患者的卵巢内膜异位囊肿标本38份、腹膜红色病变标本16份及同期在位内膜35份组织作为研究组,以及非内异症患者的子宫内膜标本20份作为对照组.采用RT-PCR半定量技术,检测上述不同组织中MMP-9 mRNA及TIMP-1mRNA的表达率及表达强度.结果两组所有标本均有TIMP-1mRNA表达,部分标本有MMP-9 mRNA表达.研究组中,卵巢异位囊肿及腹膜红色病变组织MMP-9 mRNA表达率分别为45%及56%,表达强度分别为0.46±0.22及0.33±0.12;同期在位内膜MMP-9 mRNA表达率为57%,表达强度为0.49±0.28.卵巢异位囊肿、腹膜红色病变及同期在位内膜组织 TIMP-1mRNA表达强度分别为1.67±0.79、1.45±0.68及2.31±1.21,前两者与后者比较,差异有统计学意义(P<0.05).研究组在位内膜及对照组MMP-9的表达率分别为57%及45%;表达强度分别为0.49±0.28及0.29±0.12,两组比较,差异有统计学意义(P<0.05).研究组在位内膜及对照组TIMP-1mRNA的表达强度分别为2.31±1.21及2.40±0.89.结论内异症患者在位内膜MMP-9 mRNA的表达增强,促进了内膜的异位种植.异位内膜TIMP-1mRNA的表达减弱,可促使内异症病变的发展。
