Article Abstract
Objective: To summarize the structure, regulatory mechanism, and target genes of hypoxia-inducible factor-1 alpha (HIF-1α) and to comprehensively expound its role in various chronic liver diseases, thus providing a new perspective on the treatment of various liver diseases.
Background: Liver disease, especially chronic liver disease, is a long-standing public health problem; the mortality rate due to end-stage cirrhosis and liver cancer is high worldwide and continues to grow. Moreover, there is a lack of effective targeted therapy for most liver diseases, such as fatty liver, alcoholic liver disease (ALD), and advanced liver cancer, for which drug treatment approaches are extremely limited. As the liver is a highly aerobic organ, an insufficient oxygen supply can induce a series of diseases, and HIF proteins play an important role in these processes.
Methods: Literature on HIF-1α and its effects on various liver diseases were extensively searched, and the feasibility and challenges of targeting HIF-1α to treat various chronic liver diseases were analyzed.
Conclusions: HIF-1α is widely involved in the occurrence, development, and prognosis of ALD, nonalcoholic fatty liver disease (NAFLD), acetaminophen (APAP)-induced liver injury (AILI), viral hepatitis, hepatocellular carcinoma (HCC), and other liver diseases. HIF-1α participates in complex signaling pathways, and its expression is regulated in many liver diseases. These results suggest the feasibility and clinical significance of targeting HIF-1α to treat liver diseases.

Design of Fluorinated Peptides as Biotransformed Urinalysis Biomarkers for Non-Invasive Diagnosis and Treatment of Liver Injury through Enzyme Directed Kinetics.

Urinalysis, as a non-invasive and efficient diagnostic method, is very important but faces great challenges due to the complex compositions of urine and limited naturally occurring biomarkers for diseases. Herein, by leveraging the intrinsic absence of endogenous fluorinated interference, a strategy with the enzymatically activated assembly of synthetic fluorinated peptide for cholestatic liver injury (CLI) diagnosis and treatment through F nuclear magnetic resonance (NMR) urinalysis and efficient drug retention is developed. Specifically, alkaline phosphatase (ALP), overexpressed in the liver of CLI mice, triggers the assembly of fluorinated peptide, thus, directing the traffic and dynamic distribution of the synthetic biomarkers after administration, whereas CLI mice display much slower clearance of peptides through urine as compared with healthy counterparts.

Hepatitis B (Hep B) remains a critical public health issue globally, particularly in Tibet, where vaccination rates and influencing factors among college students are yet understudied. This study applies a cross-sectional design to investigate the Hep B vaccination rate among 1,126 college students in Tibet and utilizes the expanded theory of planned behavior (ETPB) to identify vaccination behavior intention (BI) and vaccination behavior (VB). Stratified cluster sampling across three universities was used to assess behavioral attitudes (BA), subjective norms (SN), perceived behavioral control (PBC), past vaccination history (PVH) and vaccination knowledge (VK), and used structural equation modeling (SEM) for model validation and multi-group comparison.

Background And Aim: Discriminating between idiosyncratic drug-induced liver injury (DILI) and autoimmune hepatitis (AIH) is critical yet challenging. We aim to develop and validate a machine learning (ML)-based model to aid in this differentiation.
Methods: This multicenter cohort study utilised a development set from Beijing Friendship Hospital, with retrospective and prospective validation sets from 10 tertiary hospitals across various regions of China spanning January 2009 to May 2023.

Background: Gamma-glutamyl transferase (GGT) has been shown to have associations with several diseases including cancers. Previous studies have investigated the effect of GGT levels on the gastrointestinal (GI) cancer incidence. We aim to systematically investigate these studies to provide better insights into the interrelationship between GGT and GI cancers.

Background: Resmetirom, the first FDA-approved drug for nonalcoholic steatohepatitis (NASH) with fibrosis in obese patients, when combined with lifestyle modifications, improves NASH resolution and reduces fibrosis by at least one stage. Low thyroid hormone (T) levels are linked to a higher risk of developing metabolic dysfunction-associated steatotic liver disease (MASLD). Epidemiological studies have confirmed the positive correlation between hypothyroidism and MASLD.
