摘要
目的研究凋亡调节蛋白Bcl-2、Bax在功能失调性子宫出血(功血)的子宫内膜中的表达。方法采用免疫组织化学(免疫组化)方法,利用链霉素抗生物素蛋白——过氧化物酶法(sP)检测40例功血患者子宫内膜及40例子宫肌瘤标本的子宫内膜组织中Bcl-2、Bax基因的表达情况。结果(1)Bcl-2基因在正常月经周期子宫内膜组织的表达呈明显周期性变化,差异具有统计学意义(P〈0.05)。(2)Bcl-2基因随子宫内膜增生程度增加而表达逐渐增强,差异具有统计学意义(P〈0.05)。(3)Bax在正常月经周期子宫内膜组织的表达呈阳性。(4)Bax随子宫内膜增生程度增加而表达逐渐减弱,差异具有统计学意义(P〈0.05)。结论Bcl-2的过度表达和Bax的低表达可抑制子宫内膜细胞凋亡,使子宫内膜增生甚或不典型增生。与功能失调性子宫出血有密切关系。
Objective To research the expression of apoptosis related genes Bcl-2 and Bax protein in dysfunctional uterine bleeding. Methods Detecting the expression of Bcl-2 and Bax protein in 40 cases of endometrium tissue of dysfunctional uterine bleeding patients with immunohistochemistry antibiotics protein-- peroxide emzyme (SP)methods. Results (1) The expression of Bcl-2 protein changes clearly and periodically in endometrium in normal cycle, the difference is obvious (P〈0.05 ) . ( 2 ) The Bel-2 protein develops with the hyperplasia in endometrium and the expression intensity is enhanced, the difference is obvious(P〈0.05). (3) The expression of Bax gene is masculine in endometrium in normal menstrual cycle. (4) The expression of Bax gene descends gradually with hyperplasia in uterine endometrium ( P〈0.05). Conclusion Apoptosis of endometrium cell is restrained from the excessive expression of Bcl-2 protein and deficient expression of Bax protein, so the uterine endometrium gets to hyperplasia or notypical hyperplasia.
