摘    要:目的探讨细胞周期蛋白(CyclinB1)及Cyclin-Dependent kinasel(Cdc2)在子宫内膜异位症发生发展中的作用及其与卵巢激素之间的相关关系。方法采用RT-PCR,Western印迹以及免疫组织化学的方法检测了子宫内膜异位症患者(异位症组)的异位内膜(29例)和在位子宫内膜(20例)以及正常生育期的其他良性疾病妇女的子宫内膜(对照组,30例)中CyclinB1及Cdc2的表达。结果CyclinB1在异位症组异位内膜上的表达量明显高于在位内膜及对照组(P〈0.05)。异位症组在位内膜上CyclinB1的表达量与对照组相比没有显著性差异(P〉0.05)。Cdc2在各组患者中的表达差异无统计学意义(P〉0.05)。结论CyclinB1高表达可能与子宫内膜异位症异位内膜的增生相关。

Abstract:OBJECTIVE: To investigate the possible roles of cyclin B1 and cyclin-dependent kanase1 cyclin-dependent kanase1 play in the pathogenesis and development of endometriosis and their association with the ovarian hormones. METHODS: Twenty-nine specimens of ectopic endometrium tissues and 20 specimens of eutopic endometrium tissues were obtained from 29 patients with endometriosis, aged 24 approximately 46. Thirty specimens of endometrium form 30 women without endometriosis were used as controls. The intracellular location of cyclin B1 and Cdc2 was detected by microscopy. Western blotting, RT-PCR, and immunohistochemistry were employed to examine the mRNA expression and protein expression of cyclin B1 and Cdc2. Serum estrogen and progestogen were detected. RESULTS: The expression level of cyclin B1 in the ectopic endometrium from the women with endometriosis was significantly higher than that in the eutopic endometrium tissues from the women with and without endometriosis (both P < 0.05). No significant difference was found between the expression level of cyclin B1 in the eutopic endometrium tissues from the women with and without endometriosis (both P > 0.05). The Cdc2 expression levels were not significantly different among th3 3 groups and the proliferative and secretary stage of endometrium (all P > 0.05). Cyclin B1 expression level was positively correlated with the serum estrogen level, and negatively correlated with the serum progestogen level, and Cdc2 expression was not correlated with the serum sex hormone levels. CONCLUSION: The expression of cyclin B1 in the ectopic endometrium is higher than normal. Cyclin B1 may be involved in the proliferation of endometrium in endometriosis.
