摘要 目的探讨miR-146a在宫颈癌中表达水平及与临床病理参数和预后的关系,为宫颈癌患者的早期诊断、治疗提供理论及实践依据。方法选取2011年3月-2014年7月在兰州军区总医院安宁分院确诊的宫颈癌患者98例为观察组,同时选择该院门诊体检正常宫颈妇女72例为对照组,逆转录聚合酶链式反应法、酶联免疫吸附法及免疫组化方法测定miR-146a mRNA及蛋白的表达。结果观察组患者miR-146a mRNA及蛋白水平均明显高于对照组妇女,miR-146a阳性表达率高于对照组妇女,差异均有统计学意义(P<0. 05)。miR-146a表达水平与年龄差异无统计学意义(P>0. 05);与病理分型、病理学分级、TNM分期、浸润深度、淋巴血管间隙浸润、淋巴结转移相关性明显,且病理学分期越高、TNM分期越高、浸润深度越深、有淋巴血管间隙浸润、有淋巴结转移的患者miR-146a表达率越高,差异有统计学意义(P<0. 05)。miR-146a阴性患者3年生存率及生存期均明显高于miR-146a阳性患者,差异有统计学意义(P<0. 05)。结论 miR-146a在宫颈癌表达量高于正常宫颈组织,miR-146a在宫颈癌的发生发展过程中起促进作用,miR-146a低表达能获得较好的预后。
