摘要
目的观察异黏蛋白(metadherin,MTDH)与Wnt5b在乙肝相关性肝细胞癌患者中的表达及其意义,对乙肝相关性肝癌发病的作用机制进行初步探讨。方法采用免疫组织化学方法及逆转录PCR(RT-PCR)法检测54名肝癌患者及2名正常肝脏患者中MTDH和Wnt5b的表达情况,通过分析,探讨MTDH和Wnt5b表达水平与乙肝相关HCC的病理特征的相关性。结果 54例患者在乙肝相关性肝癌中MTDH表达阳性率为77.78%,Wnt5b的阳性表达率为68.51%,正常肝组织中几乎未见MTDH表达,而Wnt5b却在正常肝组织中高表达;并且MTDH和Wnt5b在乙肝相关性肝癌HCC组织中的表达与患者的年龄、性别无相关性(P>0.05),但与肿瘤直径有相关性(P<0.05)。结论 MTDH与Wnt5b共同参与HCC的进展,具有早期诊断评估HCC进展程度的价值,为乙肝相关性肝癌的诊治提供新的思路。
