摘要
目的探讨减重步行训练结合电针对大鼠脊髓损伤脑源性神经营养因子(BDNF)表达的影响。方法健康成年SD大鼠56只建立T11脊髓横断损伤模型,分为对照组、电针组、针康组各16只,其余8只为空白组。造模后3 d开始治疗。分别在治疗后1 d、7 d、14 d、21 d对各组大鼠进行BBB评分,用免疫组化法测定脊髓组织中BDNF的表达。结果治疗后,针康组BBB评分高于电针组及对照组(P<0.05);BDNF水平高于电针组和对照组(P<0.05)。结论电针结合康复训练可以促进脊髓损伤的恢复。脊髓损伤的恢复与脊髓组织中BDNF的表达有关。
Objective To investigate the mechanism of body weight support treadmill training （BWSTT） and electroacupuncture （EA） for spinal cord injury. Methods 56 adult SD rats were divided into control group （n=16）, EA group （n=16）, BWSTT-EA group （n=16） and blank group （n=8）. They were treated 3 d after operation, and assessed with Basso-Beattie-Bresnahan （BBB） scale and the brain-derived neu- rotrophic factor （BDNF） was measured in injured tissue with real time immunohistochemisty assay 1 d, 7 d, 14 d, 21 d after treatment. Re- suits The score of BBB was significantly higher in the BWSTT- EA group than in control group and EA group 1 d, 7 d, 14 d, 21 d after treat- ment （P〈0.05）, as well as the expression of BDNF （P〈0.05）. Conclusion BWSTT and EA can promote the recovery of spinal cord injury, which may associate with the expression of BDNF in injured tissue.
