摘    要:
目的观察子宫内膜癌患者临床分期、预后与Wip1表达量的关系。方法收集唐山市妇幼保健院2002年1月至2012年1月手术的120例子宫内膜癌患者,经手术切除子宫内膜癌蜡块标本作为实验组,标本均被病理证实,同期活检正常的子宫内膜标本120例作为对照组。检测Wip1在2组中的表达水平。结果 (1)Wip1免疫组化染色结果:正常子宫内膜组织细胞中,Wip1免疫组化染色阴性或微弱。子宫内膜癌组织中Wip1染色呈浅黄色至黄褐色不等。Wip1蛋白在子宫内膜癌组织中的阳性表达率为77.5%(93/120),高于正常内膜组织22.5%(27/120),差异具有统计学意义(P0.05)。(2)Wip1蛋白在子宫内膜癌组织、正常内膜组织Western blot结果:Wip1蛋白在子宫内膜癌组织的相对含量为0.635±0.023。高于正常内膜组织的0.325±0.018,两组之间比较差异具有统计学意义(P0.05)。(3)各样品实时荧光定量PCR结果:Wip1mRNA表达在子宫内膜癌组织高于正常内膜组织,基因表达值分别为0.628±0.053、0.191±0.009,两组之间比较差异具有统计学意义(P0.05)。(4)Wip1的表达水平与年龄、雌孕激素状态、HER2、淋巴结状态、TNM分期均无关(P0.05),与P53表达水平存在关联(P0.05)。结论 (1)子宫内膜癌中Wip1表达量高,而正常内膜组织表达量低。(2)Wip1的表达水平与年龄、雌孕激素状态、HER2、淋巴结状态、TNM分期均无关,与P53表达水平存在关联。

Abstract:
Objective To investigate the related factors of clinical stage and prognosis in the patients with endometrial carcinoma and their relation with proto-oncogene Wip1 expression level.Methods The paraffin samples of resected endometrial carcinoma in 120 cases of endometrial carcinoma in our hospital from January 2002 to January 2012 were collected as the experimental group,the samples were verified by pathology.Contemporaneous 120 samples of biopsy normal endometrial tissue served as the control group.The expression leve of Wipl were detected in turo groups.Results (1) In the Wip1 immunohistochemical staining results:Wip1 immunohistochemical staining was negative or weak in normal endometrial tissue cells,while showed pale yellow to yellowish-brown in endometrial cancer tissue.The positive expression rate of Wip1 protein in endometrial carcinoma tissue was 77.5%(93/120),which was higher than 22.5%(27/120) in normal endometrial tissue,the difference was statistically significant (P<0.05).(2)In the Western blot results of Wip1 protein in endometrial cancer tissue and normal endometrial tissue:the relative amount of Wip1 protein in endometrial carcinoma tissue was 0.635±0.023,which was significantly higher than 0.325±0.018 in normal endometrial tissue,the difference between the two groups was statistically significant (P<0.05).(3)In the real time quantitative qRT-PCR results of various samples:Wip1 mRNA expression level was higher than that in normal endometrial tissue,which were 0.628±0.053 and 0.191±0.009 respectively,the difference between the two groups was statistically significant(P<0.05).(4) The expression level of Wip1 had no correlation with age,estrogen and progesterone status,HER2,lymph node status and TNM stage,but had correlation with P53 expression level.Conclusion (1) The Wip1 expression amount is high in endometrial carcinoma and low in normal endometrial tissue.(2)The Wip1 expression level has no relation with age,estrogen and progesterone status,HER2,lymph node status and TNM stage,while has association with P53 expression level.
