Objective: To explore the clinical significance of HBV large protein (HBV-LP) in diagnosing viral replication, we detected the HBV-LP, HBV DNA and the hepatitis B viral markers (HBV M) in the serum of the patients infected with HBV.
Methods: HBV-LP and HBV M were analyzed by using ELISA. HBV-DNA was quantitatively detected using real-time fluorescent polymerase chain reaction.
Results: (1) No significant difference between the detectable rate of HBV DNA and HBV-LP was found in the same HBV M (P 0.05). (2) No significant difference between the positive rate of HBV DNA and HBV-LP was found in HBeAg negative patients. (3) The contents of serum HBV-LP was positively correlated with the number of HBV DNA copies.
Conclusion: There was a close correlation between the positive rate of HBV-LP and HBV DNA, and HBV-LP is a reliable serological marker that can reflect the replication of HBV.

Background: Next-generation sequencing (NGS) for Hepatitis B virus (HBV) antiviral resistance (AVR) testing is a highly sensitive diagnostic method, able to detect low-level mutant subpopulations. Our clinical virology laboratory previously transitioned from DNA hybridization (INNO-LiPA) to NGS, initially with the GS Junior System and subsequently the MiSeq. The Oxford Nanopore Technology (ONT) sequencing system was evaluated for HBV resistance testing, with regards to sequencing accuracy and turn-around time.

In this editorial, we comment on the article by Mu , published in the recent issue of the . We pay special attention to the immune tolerance mechanism caused by hepatitis B virus (HBV) infection, the pathogenesis of hepatocellular carcinoma (HCC), and the role of antiviral therapy in treating HCC related to HBV infection. HBV infection leads to systemic innate immune tolerance by directly inhibiting pattern recognition receptor recognition and antiviral signaling pathways, as well as by inhibiting the immune functions of macrophages, natural killer cells and dendritic cells.

Dendritic cells are the most potent antigen-presenting cells in immune therapeutic approaches for chronic hepatitis B (CHB) infection. Here, we developed a clinical trial to evaluate the efficacy and safety of autologous HBV vaccine-pulsed DCs and their induced T cells (HPDCT) in CHB patients. This was a randomised, prospective, open-label, multicentre, superiority study and 309 treatment-naive CHB patients were divided into HPDCT plus nucleos(t)ide analogues (NAs) group (n = 84), NAs mono-therapy group (n = 82), HPDCT plus Peg-interferon (Peg-IFN) group (n = 69), Peg-IFN mono-therapy group (n = 74).

Background: The use of laryngeal masks (LM) has increased widely today, both in anesthesia and in emergency cases. LM are available as reusable and disposable. Although reuse of disposable LM is not recommended, they are reused again after decontamination with different methods in anesthesia units in some countries.

This study validated the performance of the laboratory's blood screening system and analyzed recent trends in blood donation and screening effectiveness.
Methods: Various serum samples were used to assess the performance of hepatitis B, hepatitis C, HIV, and syphilis tests, both serological and nucleic acid tests.
