Nowadays, the stem cell therapy is a promising method in treatment of the traumatic nerve fiber injuries. And the clinical use of umbilical cord mesenchymal stem cells has been approved by FDA. However, the results are inconsistent from both human study and animal research, it often difficult to visualize the reconstruction of the motor circuits. A separate application of DTI could not precisely reveal white matter integrity. Combining blood oxygen level-dependent(BOLD)-functional magnetic resonance imaging(fMRI) with diffusion tensor-based tractography (DTT), to detect neural activities in the brain involved in the motor function restore and then using the two seeds method to reconstruct the nerve fibers between these connecting regions. The main aim of this study: i. To characterize and evaluate functional and anatomical changes of nerve fiber injuries after umbilical cord mesenchymal stem cells transplantation with BOLD drived-diffusion tensor imaging(DTI). ii. To determine the therapeutic efficiency of umbilical cord mesenchymal stem cells and also the utility of the integration of BOLD-fMRI and DTI. iii. To correlate the imaging results with the electrophysiology outcomes.

| Primary | BOLD-fMRI drived DTI scanning | All patients should be receive cranial BOLD-fMRI drived DTI scanning scanning after the transplant 6 months, and the result tells us that there is obvious reconstruction of motor circuits in nerve fiber on the damaged region; | After the transplant 6 months | |
| Secondary | FIM | All patients should receive the function independence evaluation (FIM) after the transplant 6 months , and the grading has the distinct improvement; | after the transplant 6 months | |
| Secondary | NIHSS | All patients should receive the American State-run Health Research institute apoplexy meter (NIHSS) evaluation after the transplant 6 months , and the grading has the distinct improvement; | after the transplant 6 months | |
| Secondary | Motor evoked potential | All patients should be receive motor evoked potential after the transplant 6 months, and the function of movement and sensation get obvious improvement; | after the transplant 6 months |
