【摘要】 目的：观察MMP-9，TIMP-2在子宫内膜异位症中的表达，并探讨其在子宫内膜异位症发病机制中的作用。方法：以28例子宫内膜异位症(内异症)患者为研究对象，取其异位内膜(28例)和在位内膜(25例)，以同期28例正常子宫内膜标本为对照组。采用免疫组化技术，检测MMP-9、TIMP-2在异位内膜、在位内膜和正常子宫内膜组织中的表达。应用统计软件SPSS 11.0对检测结果进行统计学分析，P＜0.05为差异有显著性。结果：①MMP-9在内异症的异位及在位内膜组织上皮中的表达均显著高于正常子宫内膜组(P＜0.01)，MMP-9在3组内膜间质中的表达无明显差异(P＞0.05)，而在正常子宫内膜的增殖期中的表达明显高于分泌期(P＜0.05)。②TIMP-2在内异症异位内膜和在位的间质和腺体中阳性染色较弱，强度以(+)为主，明显低于在正常内膜组织(++～+++)，差异均有显著性(P＜0.01，P＜0.05)。③正常子宫内膜与内异症在位内膜组织中TIMP-2的表达均受月经周期的影响而呈现周期性变化，分泌期的表达明显高于增生期(P＜0.05)；而在子宫内膜异位症异位内膜组织中失去周期性变化，增生期与分泌期无显著性差别(P＞0.05)。结论：子宫内膜异位症异位和在位内膜组织中MMP-9高表达，TIMP-2低表达，使MMPs与TIMP平衡失调，异位内膜组织侵袭降解ECM的能力增强，从而在子宫内膜异位症中的发生发展中发挥重要作用。更多还原

【Abstract】 Objective:To observe the expression of the matrix metalloproteinases-9(MMP-9)and tissue inhibitor of metalloproteinase-2(TIMP-2) in theeutopic and ectopic endometrium from women with and withoutendometriosis, there by to investigate the role of MMP-9 and TIMP-2 in thepathogenesis of endometriosis.Methods:Immunohisto-chemical streptavidin-peroxidase (S-P) were employed todetect the protein express of MMP-9 and TIMP-2 in 28 ectopic endometriaand 25 entopic endometria from women with endometriosis and 28 normalcontrol endometrium, and analyze the results by SPSS 11.0 statisticalsoftware, which finds P＜0.05 to be markedly different.Results:①The expression of MMP-9 in the epidermis of ectopic endometria and25 entopic endometria from women with endometriosis was significantlyhiger than normal controls (P＜0.01), and the expression of MMP-9 was notobvious difference in endomembrane mesenchymal with 3 groups (P＞0.05),but its expression of MMP-9 in multiplication period with normalendomembrane was significantly higer than progestational stage (P＜0.05).②The staining of TIMP-2 protein in the stromal and glandular cellsof ectopic and eutopic endometrium in endometriosis were both mildlypositive, and were significantly lower than that of normalendometrium (P＜0.01;P＜0.05).③The expression of TIMP-2 protein wereirrespective of the clinical stage (P＞0.05). The expression of TIMP-2 protein in the eutopic endometrium from women with and withoutendometriosis were all significantly relevant to the phase of themenstrual cycle (P＜0.05), while those in ectopic endometrium was notirrespective of the clinical stage (P＞0.05).Conclusions:The increased expression of MMP-9 and decreased expression of TIMP-2in the ectopic endometriosis tissue may lead to the disequilibrium ofMMP-9 and TIMP-2, which contributes to the pathogenesis of endometriosis.present higher expressions and thus lead to vascular accrementition;thedisproportion of MMP-9/TIMP-2 causes the degradation of extracellularmatrix of basal membrane, both of them play a important role in theproduction and development of ectopic endometriotic tissues.更多还原
