摘要:

背景:神经干细胞具有增殖、分化潜能,可修复脑部受损组织,神经干细胞移植治疗脑性瘫痪是重要临床方向。
目的:观察神经干细胞移植治疗脑性瘫痪患儿的运动功能变化和安全性。
方法:分离人胚胎脑神经干细胞,并进行免疫荧光染色特异性蛋白鉴定后,静脉途径移植治疗26例脑性瘫痪患儿。神经干细胞移植前及移植后3,6 个月,用粗大运动功能评价量表(GMFM)和婴幼儿精细运动发育量表(PDMS-FM)评估患儿的运动功能;检测移植前后血常规和肝肾功能,监测患儿临床不良反应。
结果与结论:6 个月随访期间无遗失病例,神经干细胞特异性蛋白检测均为阳性。神经干细胞移植3,6个月,患儿GMFM量表的A、B、C功能区得分及总分较移植前显著提高(P < 0.05,P < 0.01),而D、E功能区得分未见明显提高(P > 0.05);患儿精细运动发育商、抓握能力指数和视觉感知能力指数在细胞移植3个月未见明显提高(P > 0.05),但在移植6个月均有显著提高(P < 0.05,P < 0.01)。26例脑瘫患儿细胞移植前后血常规和肝肾功能各项指标均处于正常范围,整个移植治疗过程中未见明显严重不良反应。表明人胚胎脑神经干细胞移植较安全,能改善脑性瘫痪患儿的运动功能,且对粗大运动的治疗起效比精细运动更快。

Abstract:

BACKGROUND: Neural stem cells can repair the damaged brain tissues with potentials of proliferation and differentiation, which become one of the important directions for treating cerebral palsy.
OBJECTIVE: To observe the clinical effect and safety of neural stem cell transplantation on the treatment of cerebral palsy in children.
METHODS: Neural stem cells were isolated from human embryonic brain and identified by immunofluorescence staining, which were transplanted intravenously into 26 children with cerebral palsy. Children’s motor functions were evaluated by gross motor function measure scale and Peabody development motor scale-fine motor scale before treatment, and 3 and 6 months after treatment. Routine blood test and liver-kidney function were detected before and after treatment. Clinical adverse reactions in children with cerebral palsy were monitored.
RESULTS AND CONCLUSION: The lost cases were not found during 6 months of follow-up. Specific proteins of neural stem cells were all positive in this study. At 3 and 6 months after transplantation, the A, B, C functional area scores and total score on the gross motor function measure scale were obviously increased (P < 0.05, P < 0.01), but the C and D functional area scores were not remarkably elevated (P > 0.05). At 3 months after transplantation, the fine motor quotient, grasping subtest and visual-motor integration were not remarkably increased (P > 0.05); these scores, however, were elevated after 6 months with statistical significance (P < 0.05,
P < 0.01). The results of routine blood test and liver-kidney function in 26 children were in normal range, and there were no serious adverse reactions during the cell transplantation. Therefore, neural stem cell transplantation has high safety and good curative effects to improve the motor function of children with severe cerebral palsy, especially for gross motors.
