title: [Clinical study on hybrid bioartificial liver supporting system for acute on chronic liver failure patients].
abstract: OBJECTIVE
  To construct an hybrid bioartificial liver supporting system, and observe its effectiveness and safety on patients with acute on chronic liver failure.
  
  
  METHODS
  Hybrid bioartificial liver supporting system (HBALSS) was constructed using bioreactor with HepG2 cells transfected with human augmenter of liver regeneration (hALR) gene. 12 acute on chronic liver failure patients were divided into 2 groups randomly. The treatment group was treated with the hybrid bioartificial liver support system. The group underwent plasma exchange was used as control.
  
  
  RESULTS
  In the treatment group, four patients recovered, one patient died of hepatic encephalopathy, one patient died of hepatorenal syndrome, one patient recovered, but died of gastrointestnal bleeding after 1 year. In control group, two patients recovered, one patient underwent orthotropic liver transplantation, and three patients died of liver failure.
  
  
  CONCLUSIONS
  The hybrid bioartificial liver supporting system with HepG2 cell line was established successfully and have certain safety and effectiveness on acute on chronic liver failure patients.
