目的:探讨脊髓损伤后急性期应用辛伐他汀对大鼠脊髓神经功能修复的影响。方法:成年雌性SD大鼠32只,假手术组(A组)8只,只做椎板切除,不损伤脊髓,不给药,重物坠落法制作脊髓损伤模型24只,损伤大鼠随机分为三组:羧甲基纤维素钠溶液组(B组)...目的:探讨脊髓损伤后急性期应用辛伐他汀对大鼠脊髓神经功能修复的影响。方法:成年雌性SD大鼠32只,假手术组(A组)8只,只做椎板切除,不损伤脊髓,不给药,重物坠落法制作脊髓损伤模型24只,损伤大鼠随机分为三组:羧甲基纤维素钠溶液组(B组)、5mg/kg辛伐他汀治疗组(C组)和10mg/kg辛伐他汀治疗组(D组)(n=8)。术后1d开始灌胃给予辛伐他汀每天一次,连续治疗5周。术后1d、3d以及1～8周,进行BBB评分、斜板试验评价大鼠脊髓神经功能,在第8周时电生理检测大鼠运动及感觉功能的恢复情况,随后处死取材,病理学检查(Luxol fast blue染色)观察残余髓鞘情况。结果:术后2周时,BBB评分D组高于B组(P<0.05);建模3周～8周,BBB评分D组及C组均高于B组(P<0.05),且D组最高(P<0.05)。建模3周时,斜板试验D组及C组均大于B组(P<0.05),且4周～8周,D组角度均大于C组(P<0.05)。感觉诱发电位检查发现,D组,C组的潜伏期小于B组(P<0.05),且D组波幅高于B组(P<0.05)。病理学检查,D组,C组比B组有更多的髓鞘残余(P<0.05)。结论:辛伐他汀急性期治疗脊髓损伤可以促进大鼠损伤脊髓神经功能修复。展开更多
