Expression and significance of DLL4 protein in endometriosis

Objective To investigate the expression and significance of DLL4 in endometriosis. Methods 83 cases due to ovarian cyst surgery from December 2010 to September 2013,were selected in the Second Affiliated Hospital of Zhengzhou University,and were randomly divided into two groups in accordance with the random number table. Group A: 48 cases were induded after staining from 83 patients who were tahen a part of cyst wall;Group B: of laparoscopic ovarian cyst surgery in 83 patients,37 cases of simultaneously hysteroscopy due to fertility requirements,exclude endometrial lesions,were taken reign uterine endometrium. The American fertility association revised standard( r-AFS) in 1985 was used to divide the clinical stage:Group A: 21 cases of Ⅰ ~ Ⅱ stage,27 cases of Ⅲ ~ Ⅳ; Group B: 16 cases of Ⅰ ~ Ⅱ stage,21 cases of Ⅲ ~ Ⅳ stage; Group C: 30 cases hysteroscopic uterine septum resection with electricity due to lower mediastinal uterus were selected at the same period. The expression levels of DLL4 protein in Group A,B were detected by S-P method,and compared with the control group( Group C),then analyze its relationship with EMs stage.Results In Group A,B and C,the expression of DLL4 protein were( 144. 99 ± 10. 12),( 115. 42 ± 10. 39),( 90. 08 ± 7. 29),and there were significantly diffiences among three groups( F = 314. 220,P 0. 05); The expression of DLL4 protein atⅠ ~ Ⅱstage were significantly lower than that inⅢ ~ Ⅳ stage( P 0. 05). Conclusion DLL4 protein may play an important role in the pathogenisis of endometriosis.
