Yu Saito, Yuji Morine, Mitsuo Shimada
Japan, along with most other countries in the world, is facing an increasingly aging population with a prolonged life expectancy. Concurrently, the need for medical intervention including hepatectomy, has also increased for the elderly. Though surgical outcomes for older patients are reported to be comparable with those for younger patients, additional care in the selection of older patients for hepatectomy is considered necessary. Although the effect of aging on human liver regeneration is not fully understood, the regeneration of liver tissue after hepatectomy in elderly patients is shown to be generally worse than in younger patients and to date the mechanisms involved in the impairment of liver regeneration have not been fully clarified...

Circular RNAs (circRNAs) are a class of new found RNA molecules that have a special covalent loop structure without 5' cap and 3' tail. Researchers have found that circRNAs may be generated by intron-pairing-driven or lariat-driven circularization. They are cleared up via extracellular vesicles. They have some advantages such as stable, conservation, tissue specificity and so on. By severing as sponge of microRNAs, interacting with long non-coding RNAs, mRNA, or proteins, circRNAs regulate gene expression at transcriptional and post-transcriptional levels and contribute carcinogenesis...

Hepatic vena cava syndrome (HVCS) also known as membranous obstruction of inferior vena cava was considered a rare congenital disease and included under Budd Chiari syndrome. It is now recognized as a bacterial infection induced disease related to poor hygienic living condition. Localized thrombophlebitis of IVC at the site close to hepatic veins (HV) outlets is the initial lesion which converts on resolution into stenosis or complete obstruction, the circulatory equilibrium being maintained by development of cavo-caval collateral anastomosis...

AIM: Sofosbuvir (SOF) and ribavirin (RBV) combination therapy produces a sustained response in many patients with genotype 2 chronic hepatitis C. However, RBV-induced anemia is a troublesome side effect that may limit this treatment. Genetic variation leading to inosine triphosphatase (ITPA) deficiency is known to protect against RBV-induced hemolytic anemia. This study aimed to evaluate the relationships between the efficacy and safety of SOF/RBV treatment and ITPA gene variants. METHODS: Ninety patients with genotype 2 chronic hepatitis C treated with SOF/RBV were studied...

AIMS: Treatment to non-alcoholic steatohepatitis (NASH) is difficult due to the absence of a proven treatment and its comprehensive mechanisms. In the NASH animal model, up-regulated hepatic inflammation and oxidative stress with the resultant M1 polarization of macrophage as well as the imbalanced adipocytokines all accelerate NASH progression. As a member of TNF receptor superfamily, decoy receptor 3 (DcR3) not only neutralizes the death ligands, but also performs immune modulations...
