hUC Mesenchymal Stem Cells (19#iSCLife®-LC) in the Treatment of Decompensated Hepatitis b Cirrhosishepatitis b Cirrhosis

This experimental use umbilical cord mesenchymal stem cells in treatment of decompensated hepatitis B cirrhosis to evaluate its safety and efficacy,

This experimental is mainly aimed at people aged 18-60 years old, regardless of gender and with body mass index (BMI) between 19-25kg/m2 (including boundary value). It was decided into treatment group and control group to evaluate the effectiveness and safety of mesenchymal stem cells by peripheral intravenous injection.
