神经干细胞移植治疗帕金森病的有效性与安全性

背景：目前临床应用扩增的神经干细胞治疗神经系统疾病仍在探索阶段。目的：探讨神经干细胞移植治疗帕金森病的有效性以及安全性。方法：取12周人胚胎脑组织体外培养扩增，计数5×106-2×107制作成混悬液4-6 mL，通过腰穿、颈动脉注射途径植入30例帕金森病患者体内，1次/周，共3次。移植前后进行统一帕金森病评定量表(UPDRS)、修正Hoehn-Yahr分级量表、帕金森病Schwab & England日常活动分级量表评分。移植前后检测和评估血尿常规、肝功、肾功、不良反应。结果与结论：12周龄胚胎培养的神经干细胞可在体外稳定扩增，并且具有分化为神经元、星形胶质细胞和少突胶质细胞的能力。通过随访发现神经干细胞移植能有效控制帕金森病病理进程、恢复受损脑功能，改善患者的神经功能，无明显并发症。可见应用体外长期扩增的人类神经干细胞移植治疗帕金森病是可行和有效的。

Efficacy and safety of neural stem cell transplantation for the treatment of Parkinson’s disease

BACKGROUND: At present, the clinical application of amplified neural stem cells in the treatment of nervous system diseases is still in exploratory stage.OBJECTIVE: To investigate efficacy and safety of neural stem cell transplantation for the treatment of Parkinson’s disease.METHODS: The embryonic brain tissues aged 12 weeks were obtained for proliferation in vitro, then the brain tissues (5×106-2×107) were prepared into the 4-6 mL suspension. The suspension was injected into 30 cases of Parkinson’s disease through lumbar puncture and carotid injection, once a week, continuously for 3 weeks. Unified Parkinson’s disease rating scale, Hoehn-Yahr scale and Schwab & England Activities of Daily Living Scale scoring were performed prior to and after transplantation. Blood and urine routine, liver function, renal function and adverse reactions were detected and evaluated prior to and after transplantation. RESUTLS AND CONCLUSION:The 12-week-old embryos cultured neural stem cells could be stably amplified in vitro with the capacities of differentiation into neurons, astrocytes and oligodendrocytes. The follow-up results showed that neural stem cell transplantation could effectively control the pathological process of Parkinson’s disease, restore the damaged brain function, and improve the patient’s neurological function without significant complications. It is feasible and effective to use the in vitro long-term amplified human neural stem cell transplantation in the treatment of Parkinson’s disease.
