肝癌患者血清锌指蛋白和p53高表达的临床意义

目的:检测肝癌患者血清中锌指蛋白含量及血浆中p53基因突变性,研究与疾病发生、发展的相关性并探讨其意义。方法:采用PCR扩增p53基因外显子5-8,并对其突变和缺失进行分析;采用SEREX技术获取人类锌指蛋白,经间接ELISA方法,分析肝癌患者血清中表达水平。结合患者有无肝组织以外转移对比分析。结果:肝癌组血清中产生的抗锌指蛋白抗体水平高于正常对照组,差异有统计学意义(P<0.01)。41例肝癌患者17例显示血浆p53基因突变;有转移病灶患者22例的突变率高于无转移病灶者19例。结论:锌指蛋白的高表达提示其参与了肝癌的发生过程,而血浆p53基因突变与肝癌的发生、疾病的轻重及病灶转移有相关性,突变概率在临床鉴别诊断和治疗预后中有参考价值。

Clinical significance of ZNF216 and p53 gene in blood of the patients with liver cancer

Objective To test ZNF216 level in liver cancer patient's serum and detect the probability of p53 gene mutation,to explore its correlation with onset and development of liver cancer and the clinical significance.Methods PCR was used to amplify p53 gene exon 5-8,the SEREX technique was used to obtain ZNF216 and indirect-ELISA method to test its levels.The difference was analyzed between the patients with or without liver metastasis.Results The ZNF216 level was higher in liver cancer patients,which had statist...
