2、121)]及PHC術(shù)后7d組[0.540(0.318—0.716)](P<0.001)。在90例PHC患者中,miR一1表達水平與淋巴結(jié)有無轉(zhuǎn)移密切相關(guān),有淋巴結(jié)轉(zhuǎn)移患者中miR一1表達水平顯著低于無淋巴結(jié)轉(zhuǎn)移患者(P=0.003)。Kaplan—Meier分析顯示miR一1低表達組的生存率遠低于其高表達組,其中位生存期(月)分別為25.48和40.98(P<0.001)。Cox多變量分析顯示miR一1水平是影響PHC患者生存率的獨立危險因素之一,相對危險度為0.424(95%CI:0.183—0.984)。結(jié)論血清miR一1作為新的生物學(xué)指標對于PHC的診斷和預(yù)后的具有一定的價值。關(guān)鍵詞:原
