Human hepatocellular carcinoma (HCC) often arises from a background of liver cirrhosis. Therefore, in order to develop therapeutic strategies for HCC, an animal model bearing multifocal liver tumors accompanied by liver cirrhosis is a preferred experimental setting. In this study, we developed a rapid and reproducible method for generating such a model in rats by weekly administration of diethylnitrosamine (DEN) at doses based on body weight (BW). By adjusting the duration of administration of DEN, the animals could be induced to develop HCC alone, or HCC and liver cirrhosis simultaneously. The latter model was used for evaluating the therapeutic effects of adenoviral delivery of interferon-α (IFN-α). Our results demonstrated that targeting of IFN-α expression to the liver significantly reduced liver tumor volume and ameliorated liver cirrhosis. Mechanistic studies revealed that IFN-α gene therapy induced immunomodulatory, antiproliferative, and proapoptotic activities that were effective in the control of tumor growth, and reduced the expressions of transforming growth factor-β (TGF-β) and tissue inhibitor of metalloproteinase-1 (TIMP-1), leading to amelioration of liver cirrhosis. These results suggest that IFN-α gene therapy is a promising strategy to treat HCC patients who have concomitant liver cirrhosis.
The prognosis of patients with liver failure (LF) depends significantly on the etiology and clinical indicators. This analysis of these basic indicators can help provide a basis for the study of predictive outcome indicators. We collected the data from multiple centers in Southeast China, including subclasses of acute liver failure (ALF), subacute liver failure (SLF), acute-on-chronic liver failure (ACLF), subacute-on-chronic liver failure (SALF), and chronic liver failure (CLF).
Evaluation of of the family Boraginaceae during previous investigations determined numerous therapeutic potentials against inflammatory-related diseases. The present study evaluates the phytochemical, acute toxicity, and hepatoprotective effects of methanolic extracts of (MEAL) against thioacetamide (TAA)-induced liver injury in rats. The phytochemical profiling of MEAL followed a Folin-Ciocalteu and 10% AlCl3 procedure using a spectrophotometer.

Hepatocellular carcinoma (HCC) is a major global burden, ranking as the third leading cause of cancer-related mortality. HCC due to chronic hepatitis B virus (HBV) or C virus (HCV) infection has decreased due to universal vaccination for HBV and effective antiviral therapy for both HBV and HCV, but HCC related to metabolic dysfunction associated steatotic liver disease (MASLD) and alcohol-associated liver disease (ALD) is increasing. Biannual liver ultrasonography and serum α-fetoprotein are the primary surveillance tools for early HCC detection among high-risk patients (e.
Background: Plasma pregenomic hepatitis B virus RNA (pgRNA) is a novel biomarker in chronic hepatitis B infection (CHB). We aimed to describe the longitudinal profile of pgRNA and factors influencing its levels in CHB patients on nucleoside analogue (NUC).
Methods: Serial plasma samples from 1354 CHB patients started on first-line NUC were evaluated.
Background: Multiple and complicated hepatolithiasis can be associated with decompensated cirrhosis. Endoscopic retrograde cholangiopancreatography is unavailable for multiple and complicated hepatolithiasis, and the mainstay for decompensated cirrhosis is liver transplantation. However, due to the ethical factors and the complexity of operation, liver transplantation cannot be widely operated.
