METHODS： Patients transplanted for HCV and NASH at our institution from January 2000 to April 2011 were analyzed. All explanted liver histology and pre-trans- plant liver biopsies were examined by two specialist liver histopathologists. Patient demographics, disease free survival, explant liver characteristics and HCC features （tumour number, cumulative tumour size, vascular invasion and differentiation） were compared between HCV and NASH liver transplant recipients. RESULTS： A total of 102 patients with NA^SH and 283 patients with HCV were transplanted. The incidence of HCC in NASH transplant recipients was 16.7% （17/102）. The incidence of HCC in HCV transplant recipients was 22.6% （64/283）. Patients with NASH-HCC were statisti- cally older than HCV-HCC patients （P 〈 0.001）. A signif- icantly higher proportion of HCV-HCC patients had vas- cular invasion （23.4% vs 6.4%, P = 0.002） and poorly differentiated HCC （4.7% vs 0%, P 〈 0.001） compared to the NASH-HCC group. A trend of poorer recurrence free survival at 5 years was seen in HCV-HCC patients compared to NASH-HCC who underwent a Liver trans- plantation （P = 0.11）. CONCLUSION： Patients transplanted for NASH-HCC appear to have less aggressive turnout features com- pared to those with HCV-HCC, which likely in part ac- counts for their improved recurrence free survival.展开更多

More rigorous, controlled studies of longer duration and defined histopathological end-points comparing exercise alone and other treatment are needed before better, evidence-based physical activity modification guidelines can be established, since several questions remain unanswered.展开更多

The RME process plays an integral part in the proper trafficking and routing of receptors and ligands in the healthy cell. Thus, the missorting or altered transport of proteins during RME is thought to play a role in several diseases associated with hepatocyte and liver dysfunction. Previously, we examined in detail alterations that occur in hepatocellular RME and associated receptor functions as a result of one particular liver injury, alcoholic liver disease （ALD）. The studies revealed profound ethanol- mediated impairments to the ASGP receptor and the RME process, indicating the importance of this receptor and the maintenance of proper endocytic events in normal tissue. To further clarify these observations, studies were performed utilizing knockout mice （lacking a functional ASGP receptor） to which were administered several liver toxicants. In addition to alcohol, we examined the effects following administration of anti- Fas （CD95） antibody, carbon tetrachloride （CCh） and lipopolysaccharide （LPS）/galactosamine. The results of these studies demonstrated that the knockout mice sustained enhanced liver injury in response to all of the treatments, as shown by increased indices of liver damage, such as enhancement of serum enzyme levels, histopathological scores, as well as hepatocellular death. Overall, the work completed to date suggests a possible link between hepatic receptors and liver injury. In particular, adequate function and content of the ASGP receptor may provide protection against various toxinmediated liver diseases.展开更多
