CD14 monocytes and CD163 macrophages correlate with the severity of liver fibrosis in patients with chronic hepatitis C.

Hepatic fibrosis is a crucial pathological process involved in the development of chronic hepatitis C (CHC) and may progress to liver cirrhosis and hepatocellular carcinoma. Activated peripheral blood monocytes and intrahepatic macrophages further promote hepatic fibrogenesis by releasing proinflammatory and profibrogenic cytokines. The present study aimed to investigate the role of peripheral CD14 monocytes and intrahepatic CD163 macrophages in hepatitis C virus (HCV)-associated liver fibrosis and clarify whether serum soluble CD163 (sCD163) may serve as a fibrosis marker in patients with CHC.

LncRNA-ATB/microRNA-200a/β-catenin regulatory axis involved in the progression of HCV-related hepatic fibrosis.

Objective(s): Long noncoding RNAs (lncRNAs)-activated by transforming growth factor beta (lncRNA-ATB) is known to be involved in the invasion of hepatocellular carcinoma by regulating target genes of miR-200a. However, the role and molecular mechanisms of lncRNA-ATB/miR-200a in HCV-related liver fibrosis remains unclear. In this study, we examined the expression of lncRNA-ATB/miR-200a, and their target gene β-Catenin in liver tissues of HCV patients and hepatic stellate cells (HSCs) to elucidate the possible role of lncRNA-ATB/miR-200a axis in HSC activation and development of liver fibrosis.

Gamma-glutamyl transpeptidase to platelet ratio index is a good noninvasive biomarker for predicting liver fibrosis in Chinese chronic hepatitis B patients.

Objective To evaluate whether gamma-glutamyl transpeptidase to platelet ratio index (GPRI) can diagnose the extent of liver fibrosis in Chinese patients with chronic hepatitis B (CHB) infection. Methods This prospective observational study used liver biopsy results as the gold standard to evaluate the ability of GPRI to predict hepatic fibrosis compared with two other markers, the aspartate aminotransferase (AST) to platelet ratio index (APRI) and fibrosis-4 score (FIB-4). The clinical and demographic factors that affected GPRI, independent of liver fibrosis, were assessed using multivariate linear regression analyses.

Clinical features of elderly Chinese patients with autoimmune hepatitis.

Background/aims: To study the clinical features of elderly Chinese patients with autoimmune hepatitis.

Materials And Methods: The clinical features of 36 patients diagnosed at age >60 years were compared with those of 39 patients aged <50 years.

Results: The M:F ratio was 1:35 (>60 years) vs.

Activation of peroxisome proliferator activated receptor alpha ameliorates ethanol mediated liver fibrosis in mice.

Background: Peroxisome proliferator activated receptor alpha (PPARα) ameliorates ethanol induced hepatic steatohepatitis. However, its role in alcoholic liver fibrosis has not been fully clarified. The aim of this study was to elucidate the effect and the molecular basis of PPARα in ethanol induced liver fibrosis in mice.
