Investigators plan to recruit 24 voluntary patients of decompensate liver cirrhosis with HBV, dividing them into 3 group：1) low-dose group: 100mL with 2.5×10^7 cells；2) medium-dose group: 100mL with 5.0×10^7 cells；3) high-dose group: 100mL with 1.0×10^8 cells. Each group contains 8 patients. Investigators treat the participants with human umbilical cord mesenchymal stem cells via venous transfusion. First investigators arrange a whole test for participants, such as vital sign examination, laboratory test, ECG, CT, MRI, ultrasound etc. Investigators screen these patients with a complete eligibility criteria. Then investigators proceed the therapy in the 1st, 8th and 15th day. There are 8 times of follow-up visit for these patients, 4 times of those are proceeded during the hospitalization, while other 4 times happens after the discharge. The follow-up visit includes vital sign examination, laboratory test, ECG, CT, MRI, ultrasound, Child-Pugh grade, MELD grade, SF-36 test. These follow-up visit last 24 weeks since the first treatment. After that, investigators also arrange a survival visit through phone or clinic each 6 months, lasting another 1.5 years. The main object of this research is investigating the survival rate, promotion of the liver function, improvement of health, safety of hUC-MSCs, tolerability of patients, for exploring a new way for the therapy of decompensated liver cirrhosis with HBV.
The purpose of this study was to observe the safety ,tolerability ,Efficacy dose of human umbilical cord mesenchymal stem cells in patients of decompensated liver cirrhosis with HBV.
