ABSTRACT
BACKGROUND:In recent years, the effectiveness of stem cel transplantation in the treatment of spinal cord injury has been validated in animal models, and mesenchymal stem cel transplantation for treatment of spinal cord injury has been studied most widely. Currently, there are a number of relevant clinical studies that have shown a good prospect. OBJECTIVE:To evaluate the efficacy and safety of mesenchymal stem cel transplantation for spinal cord injury in human with a system review. METHODS:PubMed database, EMBASE database, Cochrane Library, ISI Web of knowledge, CBM database, VIP database, CNKI database and Wanfang database were searched from their start year up to July 2015 for relevant randomized clinical trials on the treatment of spinal cord injury with mesenchymal stem cel transplantation. The key words were“spinal cord injury, paraplegia, cel transplantation, transplantation, mesenchymal stem cel , bone marrow transplantation, stem cel , randomized control ed trial”in English and Chinese, respectively. RESULTS AND CONCLUSION:A total of 260 articles were retrieved, including 6 randomized clinical trials (252 cases). In the aspects of ASIA touch sensation score, overal Frankel score and daily life activity training score, the patients undergoing mesenchymal stem cel transplantation were significantly superior to those in the control group (P0.05). Compared with the control group, low fever was more common in the patients undergoing mesechymal stem cel transplantation (P0.05). These findings suggest that mesenchymal stem cel transplantation has limited efficacy in the treatment of spinal cord injury and cannot induce severe complications, but there is a need for high-quality randomized control ed trials to prove the efficiency and safety of mesenchymal stem cel transplantation for the treatment of spinal cord injury.
