中文摘要:
      目的建立检测乙肝病毒X基因突变体HBx-d382和HBx-d431特异性抗体的方法,探讨其在诊断HBV相关性肝细胞癌中的应用价值。方法通过生物信息和多肽合成的方法,制备HBx-d382和HBx-d431特异性多肽抗原。采用间接ELISA法对正常人和慢性乙肝病毒感染者和肝细胞癌病人血清中抗HBx-d382和抗HBx-d431特异性抗体进行检测。结果肝细胞癌病人血清中抗HBx-d382和抗HBx-d431抗体的阳性率均高于正常人、慢性乙肝病毒感染者(P<0.05),慢性乙肝病毒感染者抗HBx-d382和抗HBx-d431抗体的阳性率高于正常人(P<0.05)。慢性乙肝病毒感染者HBsAg(+)/HBeAb(+)/HBcAb(+)模式抗HBx-d382阳性率明显低于HBsAg(+)/HBeAg(+)/HBcAb(+)模式和HBsAg(+)/HBcAb(+)模式(P<0.05),而抗HBx-d431和抗HBxP阳性率在这些血清学模式之间无显著性差异(P>0.05)。结论抗HBx-d382和抗HBx-d431是乙肝病毒感染的一种特异性抗体,可以用于HBV携带者及慢性乙肝病人的监测,对预测肝细胞癌的发生有一定的意义。
