acute cerebral infarction, umbilical cord mesenchymal stem cells
Brief summary
The purposes of the study is to determine the safety and efficacy of treating acute ischemic stroke patients with human umbilical cord mesenchymal stem cells (hUC-MSC).
Detailed description
This is a randomized, double-blind, paralleled study. 40 patients will be separated into two groups, and receive basic treatment (Aspirin Tablet). Patients in experimental group will receive hUC-MSC once a month, total 3 times. After the treatment, investigator will have follow-up visit for 6 months, evaluate the security and efficacy of hUC-MSC.
Interventions
Allogeneic umbilical cord mesenchymal stem cells will transfusion into by forearm intravenous transplantation, 0.5 - 1 \*10\^6/kg. once a month, total 3 times.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Treatment related-adverse events counting | 26 weeks | patients will be monitored for any adverse events resulting from the treatment of Human Umbilical Cord Mesenchymal Stem Cells |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Modified Rankin Scale | 26 weeks | After the first time transplantation, follow-up visit for 26 weeks. Based on Modified Rankin Scale, counting the percentage of different symptom changes to evaluate MSC efficacy: * the percentage of participants run from 0-1, no symptom or no significant disability. * the percentage of participants run from 0-2, no symptom or slight disability. * the percentage of participants decline 2 scales compare to baseline. * the percentage of participants decline 1 scale compares to baseline. |
| Barthel activities of daily living (ADL) Index | 26 weeks | Based on Activity of Daily Living Scale (ADL) to counting the percentage of patients in following condition: * the percentage of patients with score \> 75 * the decline of Barthel ADL Index range compares to baseline. Evaluate the efficacy of MSCs treatment |
| NIH stroke scale (NIHSS) | 26 weeks | According to NIHSS changes after the treatment, evaluate MSCs efficacy by counting the percentage of patients in following condition: * the percentage of patients with score 0-1; * the percentage of patients with score declined 7 compare to baseline; * the percentage of patients with score declined 50% compare to baseline; * the declined ranges compare to baseline |
