摘　　要：背景:研究发现脐血单个核细胞治疗自闭症具有一定的效果。目的:观察人脐血单个核细胞移植治疗自闭症患儿脑脊液中神经生长因子、血管内皮细胞生长因子、碱性成纤维细胞生长因子水平的变化。方法:经腰穿蛛网膜下腔途径,以2×106/kg异体人脐血单个核细胞移植治疗30例儿童自闭症患者,1次/周,共治疗3次。结果与结论:第2次移植1周后患儿脑脊液中神经生长因子较移植前、第1次移植1周后水平增高(P<0.05),血管内皮细胞生长因子及碱性成纤维细胞生长因子水平均较移植前、第1次移植1周后水平增高,但差异无显著性意义(P>0.05)。说明人脐血单个核细胞移植治疗自闭症患儿脑脊液中神经生长因子水平明显增高,血管内皮细胞生长因子及碱性成纤维细胞生长因子变化不明显。BACKGROUND： Studies have demonstrated that umbilical cord blood mononuclear cells exhibit some effects in treatment of autism. OBJECTIVE： To detect levels of nerve growth factor （NGF）, vascular endothelial growth factor （VEGF） and basic fibroblast growth factor （bFGF） in cerebrospinal fluid of autism patients treated with umbilical cord blood mononuclear cells. METHODS： A total of 30 autism children received treatment by injection of human umbilical cord blood mononuclear cells via lumbar puncture subarachnoid cavity, once a week, for three times totally. RESULTS AND CONCLUSION： The levels of nerve growth factors were significantly greater at 1 week after the second treatment than pretreatment and 1 week after the first treatment （P 〈 0.05）. The levels of vascular endothelial growth factors and basic fibroblast growth factors were slightly, but not significantly, higher at 1 week after the second treatment than pretreatment and at 1 week after the first treatment （P 〉 0.05）. Results suggest that the levels of nerve growth factors in cerebrospinal fluid were significantly increased in autism children who received treatment of umbilical cord blood mononuclear cells, however, the levels of vascular endothelial growth factors and basic fibroblast growth factors were not influenced significantly.
