摘　　要：目的　探讨采用微粒子荧光免疫分析法 (MEIA )检测的慢性乙型肝炎 (CHB)血清HBeAg定量在CHB诊断和治疗中的价值。方法　分别采用MEIA法、酶联免疫吸附分析法(ELISA)、荧光定量聚合酶链反应法 (PCR)检测 2 4 9例CHB和 32例非CHB血清HBeAg定量、乙型肝炎病毒 (HBV)标志物 (HBVM)和HBVDNA定量。同时作肝组织活检 ,链霉菌抗生素蛋白 过氧化物酶连接法 (S P)检测肝细胞中HBcAg表达。研究血清HBeAg定量与HBeAg定性、HBVDNA定量、肝细胞内HBcAg定量以及与病理诊断间的关系。 结果　 1.检测血清HBeAgMEIA法灵敏度 (80 .2 8% )高于ELISA法 (6 9.0 1% ) ,差异有显著性 (χ2 =9.312 ,P =0 .0 0 2 ) ;2 .血清HBeAg定量与HBVDNA定量对数值间呈正相关 (r =0 .4 11,P =0 .0 0 0 ) ;3.血清HBeAg定量与肝细胞内HBcAg的半定量呈正相关 (r =0 .6 4 6 ,P =0 .0 0 0 ) ;4 .血清HBeAg定量与肝脏病理分级之间呈负相关 (r =- 0 .172 ,P =0 .0 0 6 )。结论　MEIA法检测的血清HBeAg定量是目前临床上评价HBV复制和肝脏损害程度的较敏感、较稳定、较可靠的指标 ,在CHB的诊断和治疗中有一定价值。Objective To evaluate the value of Microparticle Enzyme Immunoassay(MEIA),a quantitative assay, in the diagnosis and treatment of chronic hepatitis B (CHB). Methods MEIA, Enzyme linked immunoabsorbent assay (ELISA), and quantitative PCR were used to detect e antigen, hepatitis B serum markers, and the quantity of HBV DNA in 249 CHB patients and 32 non CHB patients respectively. Expression of HBcAg in Liver tissue was detected by using S P method. These measures were used to illuminate the relationships among serum e antigen quantity, hepatitis B serum markers, the quantity of HBV DNA, the quantity of HBcAg in hepatocytes, and pathologic diagnosis of liver tissues. Results 1. The sensitivity of MEIA (80.28%) to detect serum e antigen is higher than that of ELISA (69.01%)( χ 2=9.312, P =0.002).2. The serum e antigen quantity is positively correlated with the logarithm of the quantity of HBV DNA ( r =0.411, P =0.000). 3. The level of serum e antigen is positively correlated with the semi quantitative of HBcAg in hepatocytes ( r =0.646, P =0.000). 4. The serum e antigen quantity is negatively correlated with pathologic degree of liver tissues ( r =-0.172, P =0.006). Conclusions MEIA is a sensitive, stable, and reliable method to assay the serum e antigen quantity which could be used to evaluate the replication of HBV and the degree of liver damage.
