| Abstract | R493%R245; 目的:观察夹脊电针结合跑台训练对大鼠坐骨神经离断损伤后的胫骨骨密度、血管体积和数量、血管内皮生长因子(vascular endothelial growth factor,VEGF)表达的影响,为夹脊电针结合跑台训练促进坐骨神经离断损伤大鼠胫骨重建提供理论依据.
方法:将180只SD大鼠随机分为正常对照组、模型对照组、夹脊电针组、跑台组、夹脊电针+跑台组(以下简称结合组),每组36只;再按术后干预2、4、8周分为3个亚组,每个亚组12只.行坐骨神经离断损伤缝合术进行造模.正常对照组无任何干预;模型对照组造模后无干预;夹脊电针组、跑台组和结合组于术后第3天分别开始进行夹脊电针、跑台训练以及二者结合治疗.采用Micro-CT扫描并分析胫骨骨密度;血管造影分析胫骨近端血管的数量和体积;RT-PCR和Western Blot检测胫骨VEGF mRNA和蛋白的表达;ELISA测定胫骨骨髓中VEGF浓度.
结果:在干预2、4、8周后,模型对照组大鼠的胫骨骨密度、近端血管体积和数量、骨组织VEGF mRNA和蛋白表达以及骨髓中VEGF浓度均低于同一时间点的正常对照组(P＜0.05).而随着干预时间的延长,夹脊电针组、跑台组和结合组大鼠的胫骨骨密度、近端血管体积和数量、骨组织VEGF mRNA及蛋白表达和骨髓中VEGF浓度均显著高于同一时间点的模型对照组(P＜0.05),且在各时间点以结合组表达更优(P＜0.05).
结论:夹脊电针结合跑台训练可能通过上调胫骨及骨髓中VEGF的表达,改善胫骨骨密度. |

| Abstract_FL | Objective:To observe the effects of Jiaji electroacupuncture combined with treadmill running training on tibial bone density,volume and number of blood vessels and VEGF expression after sciatic nerve amputation injury in rats,and provide theoretical basis for promoting tibial reconstruction after Jiaji electroacupuncture combined with treadmill running training.
Method:A total of 180 SD rats were randomly divided into normal control group,model control group,Jiaji electroacupuncture group,treadmill group,combination treatment group(Jiaji electroacupuncture+treadmill),with 36 rats in each group.After 2,4 and 8 weeks of postoperative intervention,the rats were divided into 3 subgroups,12 in each subgroup.The model was made by suture of sciatic nerve dissociation injury.The normal control group received no intervention;the model control group received no intervention post-modeling.The Jiaji electroacupuncture group,treadmill group and combined group began to receive Jiaji electroacupunc-ture,treadmill training and combined treatment respectively on the 3rd day after surgery.Bone density of tibia was analyzed by Micro-CT scan.The number and volume of the proximal tibial vessels were analyzed by angi-ography.The expression of VEGF mRNA and protein in tibia was detected by RT-PCR and Western Blot.VEGF concentration in tibial bone marrow was determined by ELISA.
Result:At 2,4 and 8 weeks post-intervention,the model control group showed significantly lower tibial bone mineral density,proximal vascular volume and quantity,VEGF mRNA and protein expression in bone tissue,and VEGF concentration in bone marrow compared to the normal control group at the same time point(P＜0.05).However,overtime,the tibial bone mineral density,the volume and number of proximal blood ves-sels,VEGF mRNA and protein expression in bone tissue and VEGF concentration in bone marrow of rats in the Jiaji electroacupuncture group,treadmill group and combination group were significantly higher than those in the model control group at the same time point(P＜0.05),and the combination group showed the most pro-nounced effects(P＜0.05).
Conclusion:Jiaji electroacupuncture combined with treadmill training may improve tibial bone mineral density by up-regulating the expression of VEGF in tibia and bone marrow. |
