Catheterization of the gallbladder: A novel mouse model of severe acute cholangitis.

Aim: To establish a severe acute cholangitis (SAC) model in mice.

Methods: Cholecystic catheterization was performed under the condition of bile duct ligation (BDL). Trans-cholecystic injection of lipopolysaccharide (LPS) was defined as the SAC animal model.

Gastric fistula secondary to drainage tube penetration: A report of a rare case.

Cases of gastric fistula secondary to drainage tube penetration have rarely been reported. The current study presents a case of gastric penetration caused by misplacement of a drainage tube after a splenectomy. The patient was admitted to the Department of Hepatobiliary Surgery, (Shaoxing People's Hospital, Shaoxing Hospital of Zhejiang University, Shaoxing, Zhejiang, China) for blunt abdominal trauma due to injuries sustained in an automobile accident.

Molecular hydrogen attenuates hypoxia/reoxygenation injury of intrahepatic cholangiocytes by activating Nrf2 expression.

Hypoxia/reoxygenation (H/R) injury of cholangiocytes causes serious biliary complications during hepatobiliary surgeries. Molecular hydrogen (H2) has been shown to be effective in protecting various cells and organs against oxidative stress injury. Human liver cholangiocytes were used to determine the potential protective effects of hydrogen against cholangiocyte H/R injury and explore the underlying mechanisms.

Lactulose accelerates liver regeneration in rats by inducing hydrogen.

Background: Oxidative stress and inflammation are implicated in the process of liver regeneration. Lactulose orally administered can be bacterially fermented and induces dramatic amounts of endogenous hydrogen. Hydrogen has been confirmed to have antioxidant and anti-inflammatory properties.
