摘要
目的探讨血管生成素-2(ANG-2)和内皮抑素(ENS)在子宫内膜异位症发生发展中的作用。方法卵巢子宫内膜异位症患者25例,24例无内膜病变者为对照组。留取子宫内膜,用免疫组化染色法检测ANG-2和ENS在子宫内膜中的表达,用酶联免疫吸附测定法检测腹腔液中ANG-2和ENS的蛋白含量。结果ANG-2在在位子宫内膜组织中的阳性表达率显著高于异位内膜和对照组,异位内膜中阳性表达率显著高于对照组;ENS在异位内膜组织中的表达明显高于在位内膜和对照组,在位内膜的ENS表达明显高于对照组;ANG-2及ENS表达强度在子宫内膜异位症Ⅰ、Ⅱ期与Ⅲ、Ⅳ比较无显著差异。异位组腹腔液的ANG-2、ENS含量和ANG-2/ENS比值均显著高于对照组。结论ANG-2和ENS在子宫内膜异位症血管生成中起到重要的作用,参与调节异位病灶的发生和进展。
Objective To explore the effect of Angiopoietin-2 （ANG-2） and Endostatin （ENS） in patho genesis and development of endometriosis. Methods Twenty-five endometriosis cases and 24 controls were enrolled. ANG- 2 and ENS in endometrium were detected by Immunohistochemistry. The concentrations of ANG-2 and ENS in peritoneal fluid were measured with enzyme linked immunoabsorbant assay. Results In the EMs group, ANG-2 positive rate in eutopic endometrium was significantly higher than that of ectopic endometrium. The ANG-2 positive rate in ectopic endometrium was significantly higher than that of control group ; in EMs group, the ENS positive rate in ectopic endometrium was significantly higher than that in eutopic endometrium. The ENS positive rate in eutopic endometrium was significantly higher than that in control group. There was no significant difference of ANG-2 or ENS between stage Ⅰ - Ⅱ and stage Ⅲ - Ⅳ. In peritoneal fluid, ANG-2 and ENS concentration and ratio of ANG-2/ ENS in endometriosis were significantly higher than that in controls. Conclusion The effect of angiopoietin-2 and endostatin in angiogenesis of endometriosis are important play a role in pathogenesis and development of the endometriosis.
