摘要 为了探讨血清乙肝病毒大蛋白在HBeAg阴性与低水平HBV-DNA乙肝患者中的检测意义。对162例HBV感染者及47名健康对照血清采用酶联免疫吸附试验检测乙肝病毒大蛋白、乙肝病毒前S1抗原、病毒前S2抗原及乙肝病毒标志物;FQ-PCR定量检测HBV-DNA。结果显示:162例HBV感染者血清中,HBV-LP浓度与HBV-DNA拷贝数间具有良好的正相关性(rs=0.64,P<0.001),不同HBV-DNA拷贝数组别间HBV-LP浓度存在差异显著性(P<0.01);HBV-LP与HBV-DNA、HBeAg、HBVpreS2、HBVpreS1间均关联显著(P<0.01)。HBV-LP与HBV-DNA、HBeAg、HBVpreS2、HBVpreS1间阳性率均存在差异显著性(P<0.05),HBV-LP阳性率为84.57%,较HBV-DNA、HBeAg、HBVpreS2、HB-VpreS1均敏感。其中HBeAg阴性组中HBV-LP与HBVpreS1、HBVpreS2、HBV-DNA间阳性率均存在差异显著性(P<0.05),HBV-LP阳性率为76.77%(76/99),较HBV-DNA,HBVpreS2,HBVpreS1均高(P<0.01);DNA阴性组中HBV-LP与HBVpreS2、HBVpreS1、HBeAg间阳性率均存在差异显著性(P<0.05),HBV-LP阳性率为73.33%,较HB-VpreS2、HBVpreS1、HBeAg均高。血清HBV-LP浓度是反映血清HBeAg阴性和低水平DNA的HBV感染者体内病毒复制、疾病进程、疗效与预后判断的新的敏感监测指标。 In 162 HBV patients and 47 healthy individuals,ELISA assay was used to detect the presence of the large surface protein of HBV(HBV-LP),preS1 and preS2 in serum of patients with negative HBeAg and low level of HBV-DNA and the fluorescene quantitative PCR technique was applied to detect the HBV-DNA.It was found that positive correlation existed between concentration of HBV-LP and copy number of HBV-DNA(rs=0.64,P<0.001),and the concentration of HBV-LP showed significant difference in different HBV-DNA copy ...
