RESUMEN
OBJECTIVE: To explore the significance of serum hepatitis B virus large protein( HBV-LP), HBV-DNA and markers of hepatitis B virus (HBV-M)in the diagnosis of viral replication. METHODS: Serum HBV-DNA level was quantitatively detected using PCR Real-time polymerase chain reaction, HBV-LP was detected by enzyme-linked immunosorbent assay (ELISA) and HBV markers expression were measured by chemiluminescence immunoassay method in 1886 cases of seurm. RESULTS: The results of hepatitis virus large protein (HBV-LP) detection and the detection results of HBV-DNA was no significant difference (chi2 = 1.142, P > 0.05). HBV-DNA logarithm of copies and A vaule of HBV-LP was a positive correlation (r = 0.487, P < 0.01). HBV-DNA copies of different groups was significantly different from HBV-LP A values (F = 7.772, P < 0.01). The results of HBV-LP and HBV-DNA detected in different patterns of HBV-M were not significantly different. In 36 healthy people,the detecting results of HBV-DNA and HBV-LP are negative. CONCLUSION: There is a good correlation between the copies of HBV-DNA and the levels of HBV-LP. HBV-LP expression can reflect the replication of HBV.
