66 patients from 5 dialysis centers were surveyed for the prevalence of HBV markers. Their immune status was evaluated by studying parameters of cellular and humoral immunity. Results showed that all patients had depressed T cell numbers while B cell counts, IgG, IgA, IgM, IgD and C3 levels were normal. However, the group of patients who had persistent HBs antigenemia also had persistence of HBeAg, negative responsiveness to skin testing and high IgE levels. The group with HBsAb had negative reactions for skin testing, and the group with no HBV markers had no further abnormalities. These results suggest that the presence and type of HBV marker influences the immune pattern in the hemodialyzed patient.

Objective: To analyze the clinical effectiveness of Entecavir (ETV) and Tenofovir Disoproxil Fumarate (TDF) Tablets for the treatment of chronic hepatitis B (CHB).
Methods: Clinical data from 100 CHB patients admitted to our hospital from April 2022 to April 2024 were retrospectively reviewed. Of these, 45 cases in the control group received ETV, and 55 cases in the research group received TDF tablets.
Background: Due to the unique geographical and climatic conditions in Nagqu (Tibet), the blood station laboratory was only fully established and accredited by 2020. 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.

Unlabelled: Chronic Hepatitis B (CHB) remains a major public health problem, leading to various complications such as liver fibrosis, cirrhosis, and hepatocellular carcinoma. The existing diagnostic markers for Hepatitis B virus (HBV) are limited in distinguishing different CHB phases and intra-hepatic viral replication activity. In the past few years, several non-invasive potential blood markers that reflect viral intra-hepatic replicative state more accurately have been in progress and are gaining importance.

Background And Aims: Hepatitis B virus (HBV) infection contributes to hepatocellular carcinoma (HCC) tumorigenesis, drug resistance, and recurrence, although the underlying molecular mechanisms remain unclear. Recent studies suggest that HBV infection may be associated with liver cancer stem cells (LCSCs), but the exact mechanisms are yet to be resolved. In this study, we aimed to analyze the role of HBV infection in regulating the stemness of HCCs, which is closely linked to drug resistance.

Backgrounds And Aims: CD8+T cells are crucially associated with the fight against hepatitis B virus (HBV) infection. CD161 has been shown to express remarkably on HCV-specific CD8+T cells. However, the accurate function of CD161+CD8+T cells in HBV immunity or pathogenesis remains undetermined.
