The expression and significance of ERα,ERβ,PR,and Bcl-2 of endometrial polyps

Objective To investigate the expression and significance of ERα (estrogen receptorα),ERβ(estrogen receptorβ),PR,and Bcl-2 of endometrial polyps.Methods 50 cases of endometrial polyp patients were studied.And 45 cases of endometrial normal subjects were selected as the control group.The enzyme-linked immunosorbent assay was used to detected the FSH,LH,E2,P,T and PRL six levels of the two groups.And endometrial ERα two groups of patients,ERβ,PR and Bcl-2 expression was studied.Results The FSH,LH,E2,P,T and PRL six levels of the two groups were no significant difference(P ＞0.05).Polyps in patients with proliferative phase of ERα,ERβ expression levels of the normal group had no significant difference (P ＞ 0.05),the expression level of PR(0.47 ± 0.02) point was significantly lower than that of the normal group(0.53 ± 0.02) point (t =10.383,P =0.000),Bcl-2 expression levels(0.53 ± 0.04) point was significantly higher than that of the normal group (0.49 ± 0.02) point (t =4.322,P =0.000).Polyps in patients with secretory phase of ERα,Bcl-2 expression levels (0.46 ± 0.07;0.43 ±0.04)point were significantly higher than that of the normal group (0.37 ± 0.05 ;0.39 ± 0.03) point (t =5.007,P =0.000; t =3.834,P =0.000),the expression level of PR (0.42 ± 0.02) point was significantly lower than that of the normal group (0.46 ± 0.01)point(t =8.486,P =0.000),there was no significant difference in expression levels between the two groups ERβ(P ＞0.05).Between the two groups displayed,ERα,PR proliferative phase of the normal group and the polyp group,the expression levels of Bcl-2 were significantly higher than that of the secretory phase (P ＜ 0.05).Conclusion The increase of the ERα,Bcl-2 expression levels,and the reduction of the level of PR expression in patients with endometrial polyps are closely related.
