摘要
背景:研究表明,神经节苷脂(GM1)通过激活神经营养因子,抑制毒性产物对神经元的损害,并且能够减少兴奋性氨基酸所引起的神经细胞的死亡起到促进神经细胞修复的作用。目的:神经干细胞移植同时应用GM1,观察两者对脑损伤大鼠恢复的影响。方法:取健康Wistar大鼠制成重型液压颅脑损伤模型,随机分成3组:损伤组(培养液移植组),神经干细胞移植组,神经干细胞+GM1组。脑损伤后4d用RT-PCR、WesternBlot检测脑组织中AQP4基因表达和蛋白合成的变化,并于脑损伤后24h,3d及伤后1,2,3,4周行动物神经学缺损评分,在脑损伤后21~28d进行Morris水迷宫试验。4周后处死大鼠行免疫组化、苏木精-伊红染色组织学观察。结果及结论:脑损伤后4d脑损伤周围组织AQP4及其mRNA的表达损伤组高于神经干细胞移植组,神经干细胞移植组高于神经干细胞+GM1组(P<0.05);移植后1,2,3,4周,大鼠神经学缺损评分及水迷宫测试结果显示,神经干细胞移植可明显改善重型颅脑损伤后大鼠的神经功能,联合应用GM1有协同效果。移植4周后苏木精-伊红染色神经干细胞+GM1组出现典型的神经细胞样形态学改变且软化灶消失。免疫组化染色结果显示大鼠损伤灶脑组织中的BrdU阳性细胞数神经干细胞+GM1组高于NSCs移植组和损伤组。提示神经干细胞移植可明显改善重型颅脑损伤后大鼠的神经学功能,联合应用GM1有协同效果。
