目的:观察联合应用MEK抑制剂(U0126)和硫酸软骨素酶ABC对大鼠急性脊髓损伤后胶质瘢痕中细胞成分及细胞外基质成分形成的影响,探索胶质瘢痕中不同组成成分与神经功能恢复之间的关系,初步研究联合应用MEK抑制剂和硫酸软骨素酶ABC对神经功能恢复的影响,进一步完善抑制脊髓损伤后胶质瘢痕形成的新思路并探寻脊髓损伤治疗的新策略。 方法:选择雌性SD大鼠96只。将实验动物随机分为脊髓损伤对照组(I组,n=24)、脊髓损伤后ChABC干预组(II组,n=24)、脊髓损伤后U0126干预组(III组,n=24)及脊髓损伤后ChABC联合U0126干预组(Ⅳ组,n=24),各组又分为伤后1d,伤后7d,伤...Object: The aim of this study was to observe the effect of MEK inhibitors (U0126) combined with chondroitin sulfate ABC on the composition of glial scars following spinal cord injury (SCI) in a rat model, explore the relationship between the different components of glial scar and the neurological function recovery, primarily investigate the influence of combined use of MEK inhibitors and chondroi...学位:医学硕士院系专业:医学院_外科学学号:2452011115339
