摘要目的研究Ⅰ型子宫内膜癌组织中长链非编码核糖核酸GAS5（lncRNA-GAS5）的表达及意义。方法分别采集40例Ⅰ型子宫内膜癌患者及40例因子宫肌瘤等良性病变就诊患者的子宫内膜的组织标本，应用实时荧光定量逆转录聚合酶链反应法分别检测两种不同的子宫内膜组织中lncRNA-GAS5的表达，并结合Ⅰ型子宫内膜癌患者的病理和临床资料将检测的数据进行统计分析。结果与正常子宫内膜组织相比较lncRNA-GAS5在Ⅰ型子宫内膜癌组织中表达下调，两组间的差异具有统计学意义（P<0.05）。lncRNA-GAS5在期别较晚（Ⅲ~Ⅳ期）的Ⅰ型子宫内膜癌患者中低表达，低于期别较早（Ⅰ~Ⅱ期）的患者；在Ⅰ型子宫内膜癌有淋巴结转移的患者中lncRNA-GAS5呈现低表达，低于无转移者，且差异均具有统计学意义（P<0.05）。在不同病理分级、肌层浸润深度，不同年龄的Ⅰ型子宫内膜癌患者中lncRNA-GAS5表达差异不显著（P>0.05）。结论子宫内膜癌组织中lncRNA-GAS5表达下调，在期别较晚（Ⅲ~Ⅳ期）及有淋巴结转移的Ⅰ型子宫内膜癌患者中也呈现低表达，lncRNA-GAS5可能在Ⅰ型子宫内膜癌发病和转移过程中起到了抑制作用。

Abstract：Objective To investigate the expression and significance of lncRNA-GAS5 in typeⅠendometrial cancer tissues. Methods Tissue samples were collected from 40 patients with typeⅠendometrial carcinoma and 40 patients with normal endometrial tissues for benign diseases such as uterine fibroids. The expression of lncRNAP-GAS5 in different endometrial tissues was detected by reverse transcription-polymerase chain reaction. And the detected data were combined with the clinicopathological data of patients with endometrial carcinoma for statistical analyses. Results Compared with normal endometrial tissues, the expression of lncRNA-GAS5 was down-regulated in typeⅠendometrial cancer tissues, and the difference between the two groups was statistically significant(P<0.05). The expression of lncRNAP-GAS5 in typeⅠendometrial cancer tissues of stage Ⅲ~Ⅳ was lower than that in endometrial cancer tissues of stage Ⅰ~Ⅱ. The relative expression quantity of lncRNAP-GAS5 in typeⅠ endometrial cancer with lymph node metastasis was lower than that in typeⅠendometrial cancer without lymph node metastasis with statistically significant(P<0.05). There was no difference in lncRNAP-GAS5 expression between different pathological grades, myometrial inva and ages of typeⅠendometrial carcinoma patients (P>0.05). Conclusions lncRNA-GAS5 was down-regulated in typeⅠendometrial cancer tissues,especially in typeⅠ endometrial cancer at advanced stage (Ⅲ~Ⅳ stage) and with lymph node metastasis, it may play an inhibitory role in the occurrence and metastasis of typeⅠendometrial carcinoma.
