摘要: 目的:探讨芳香化酶细胞色素P450(P450arom)在子宫内膜异位症(EM)患者子宫内膜中的表达及临床意义。方法:采用免疫组织化学方法检测63例EM患者、40例妇科良性疾病患者及30例正常对照组患者子宫内膜中P450arom蛋白的表达,并结合EM患者的临床分期等进行比较分析。结果:P450arom蛋白在正常对照组子宫内膜中无表达;在良性疾病对照组中阳性检出率为17.50%(7/40),表达水平(0.22±0.16);在EM患者子宫内膜中阳性检出率为81%,表达水平(0.57±0.26),差异有统计学意义(P<0.05)。P450arom蛋白表达在增生期与分泌期差异无统计学意义(P>0.05)。P450arom蛋白表达随EM临床分期增加呈增强趋势,但差异无统计学意义(r=0.226,P>0.05)。结论:P450arom在EM患者子宫内膜中的高表达与EM的发生有关;检测P450arom蛋白在子宫内膜的表达可作为诊断EM新的参考指标。

Abstract: Objective: To investigate the expression and clinical significance of P450arom in patients endometriosis. Methods: Immunohistochemistry was used to detect the expression of P450arom in the endometrium. All data were statistically analyzed. Results: The the expression level of P450arom was significantly higher in patients with endometriosis than the control group( P =0.0006 ).Its sensibility was 80.95%, the specifility was 82.50% in the diagnosis of endometriosis. Conclusion: The higher-expression of P450arom in endometrium was related to the development of endometriosis. P450arom may help evaluate endometriosic development.
