High expression of angiopoietin-2 and endostatin in endometriosis / 基础医学与临床

ABSTRACT

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 stageⅠ～Ⅱand 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.
