Résumé
<p><b>OBJECTIVE</b>It was to explore the application of the hepatitis B virus large proteins (HBV-LP) in public health physical examination through clinical testing of HBV-LP in Catering practitioners, students and soldiers of New requisition etc.</p><p><b>METHODS</b>709 samples of HBV infection people were collected in public health physical examination and all collected samples were detected. ELISA was used to detect HBV serum markers (HBV-M) and HBV-LP. Real-time PCR was applied to detect quantity of HBV DNA.</p><p><b>RESULTS</b>(1) The detectable results of HBV-LP and HBV DNA were no statistical significance in 709 samples. (2) The detectable results of HBV-LP and HBV DNA were also no statistical significance in different models of HBV infection patients. The values of chi2 and P were respectively 2.67, 0.60, 0.00 and 0.10, 0.44, 1.00. S/A of HBV-LP and the copies of HBV-DNA had a positive relationship (r = 0.959, P < 0.05).</p><p><b>CONCLUSION</b>HBV-LP could reflect the level of hepatitis B virus replication and be used to judge the level of hepatitis B virus replication in people of public health physical examination. HBV-LP may be worth using widely in physical examination.</p>
