This study is to evaluate the safety and efficacy of umbilical cord blood mononuclear cells transplantation in liver cirrhosis patients.

Decompensated liver cirrhosis (LC), a life-threatening complication of chronic liver disease, is one of the major indications for liver transplantation. Recently, umbilical cord blood mononuclear cells transfusion has been shown to lead to the regression of liver fibrosis in animal model. The investigators thus investigated the safety of the therapy with life signs like temperature, pulse, blood pressure, the incidence of hepatocellular carcinoma and mortality and so on. And the efficacy was evaluated with the measurement of alanine aminotransferase (ALT), glutamic oxaloacetic transaminase (AST), total bilirubin (TBIL), direct bilirubin (DBIL), albumin (ALB), cholinesterase (CHE), prothrombin time (PT) and child-pugh score.

Inclusion Criteria:

• Patients with hepatocirrhosis: according to the standard of child- pugh, liver functions to achieve class A or B patients, Including C class patients but can achieve B class after treatment

Exclusion Criteria:

1. Patients with C class by child-pugh score
2. Patients in the acute phase of severe hepatitis
3. Patients have been diagnosed with cancer of the liver
4. Patients with severe cardiopulmonary cerebral disease, and in the failure state
5. Patients in Highly allergic constitution
6. Patients with moderately severe mental disease
