This trial aims to investigate the use of donated cord blood stem cells in the treatment of liver failure resulting from cirrhosis. The trial is being conducted by the General Hospital of Chinese Armed Police Forces and the Hebei Medical University First Hospital and expects to recruit 60 patients with severe to moderate hepatic failure/cirrhosis between November 2012 and July 2014. They propose to recruit 30 participants who will be randomly divided into two groups. One group will receive an infusion of mesenchymal stem cells obtained from donated umbilical cord blood. The second group will receive standard anti-viral treatment (lamuvidine and adefovir dipivoxil). Participants will be monitored for complications and changes in clinical condition.
