Hepatic stellate cell (HSC) activation is the essential pathological process of liver fibrosis (LF). The molecular mechanisms regulating HSC activation and LF are incompletely understood. Here, we explored the effect of transcription factor SRY-related high mobility group box 7 (SOX7) on HSC activation and LF, and the underlying molecular mechanism.

However, existing clinical detection technologies inevitably cause certain inaccuracies, leading to delayed or unwarranted treatment. Here, we introduce a label-free plasmonic biosensing method based on the thickness-sensitive plasmonic coupling, combined with supervised deep learning (DL) using neural networks.

HBV can upregulate the expression of the transcription factor Yin Yang 1 (YY1) in in vitro cytological experiments, suggesting an association between YY1 and HBV infection. However, data on YY1 expression in chronic hepatitis B (CHB) patients are lacking.

Aim: To estimate HDV prevalence and investigate viral marker quantity trends in patients with hepatitis D.
Methods: We collected 5594 serum samples from patients with hepatitis B in Jilin Province, China (3293 males and 2301 females, age range of 2 to 89 years).
The aim of this study was to determine whether the age-Male-ALBI-Platelet (aMAP) score is applicable in community settings and how to maximise its role in risk stratification. A total of thousand five hundred and three participants had an aMAP score calculated at baseline and were followed up for about 10 years to obtain information on liver cancer incidence and death. After assessing the ability of aMAP to predict liver cancer incidence and death in terms of differentiation and calibration, the optimal risk stratification threshold of the aMAP score was explored, based on absolute and relative risks.

A two-sample Mendelian randomization (MR) approach was used to investigate the causal relationship between systemic inflammatory regulators and ACLF. The study analyzed 41 cytokines and growth factors from 8,293 individuals extracted from a genome-wide association study (GWAS) meta-analysis database involving 253 ACLF cases and 456,095 controls.

There was a rapid wave of infections by the Omicron variant in Jilin Province (China) during spring 2022. We examined the effectiveness of inactivated vaccines against Omicron using real-world data from this epidemic.

Here, we develop a completely alternative approach relying on a two-step protocol that includes the self-assembly of gold nanoparticles (GNPs) at the water-oil interface and subsequent annealing-assisted regulation of gold nanogap. Our optimized thermal-annealing GNPs (TA-GNP) platform generates adequate hot spots, and thus produces high-density electromagnetic coupling, eventually enabling 240-fold fluorescence enhancement of probed dyes in the near-infrared region.

Methods: Liver biopsies and paired blood samples were obtained from HBeAg-positive patients before and after 48 weeks of entecavir treatment, and a probe-based capture strategy was applied for analyzing the HBV integrations in these samples. Serum HBV markers, including viral DNA, pgRNA, and HBsAg, were longitudinally assessed.
Background And Aims: To systematically summarize the prevalence of alcohol-related liver disease (ALD) and the alcohol-attributable proportions of liver cirrhosis and hepatocellular carcinoma (HCC) cases in Asia.
Methods: The Embase, PubMed, Web of Science, Cochrane, CINAHL, WanfangMed and China National Knowledge Infrastructure databases were searched from 01 January 2000 to 01 December 2021 for reports of ALD prevalence and alcohol-attributable proportions of liver cirrhosis/HCC in Asian populations. Study characteristics were extracted, and meta-analyses were conducted.
Background And Aim: Quantitative hepatitis B core antibody (qAnti-HBc) level has been reported to predict significant liver inflammation in treatment-naïve chronic hepatitis B patients. However, little evidence has been revealed that qAnti-HBc alone or with other serum parameters in predicting moderate to severe hepatic inflammation in HBeAg-positive immune active patients treated with entecavir (ETV).
Methods: A total of 142 patients with HBeAg-positive immune active hepatitis were recruited in our study.
