目的:旨在探讨基质金属蛋白酶-9(matrix metalloproteinase-9,MMP-9)在异种嗅鞘细胞移植联合中药干预下脊髓损伤中的作用。方法:将188只SD大鼠随机分为正常对照组、单纯损伤组、异种嗅鞘细胞移植组、异种嗅鞘细胞移植联合中药治疗组,损...目的:旨在探讨基质金属蛋白酶-9(matrix metalloproteinase-9,MMP-9)在异种嗅鞘细胞移植联合中药干预下脊髓损伤中的作用。方法:将188只SD大鼠随机分为正常对照组、单纯损伤组、异种嗅鞘细胞移植组、异种嗅鞘细胞移植联合中药治疗组,损伤组又设1、3、7、14、28 d 5个时相点,免疫组织化学技术检测MMP-9的表达,同时电镜观察血脊髓屏障的变化。结果:脊髓损伤后血脊髓屏障的超微结构不同程度损害、MMP-9表达上调,经干预治疗后出现一定程度的恢复,MMP-9表达下调。结论:脊髓损伤后MMP-9表达水平增加与伤后血脊髓屏障损害的发生、发展密切相关,MMP-9在脊髓损伤后血脊髓屏障损害的病理生理过程中起重要作用。异种嗅鞘细胞移植联合中药对脊髓损伤有较好的修复作用。展开更多
