夹脊电针和神经松动术对兔坐骨神经损伤后轴突再生和血清神经营养因子的影响

摘要

Objective To observe the effects of Jiaji electroacupuncture and neurodynamic mobilization technique on axon regeneration and content of brain-derived neurotrophic factor (BDNF) and ciliary neurotrophic factor (CNTF) in rabbits with sciatic nerve injury. Meth-ods 30 male adult rabbits were assigned to sham (A, n=6), model (B, n=6), neurodynamic mobilization (C, n=6), Jiaji electroacupuncture (D, n=6), and Jiaji electroacupuncture combine with neurodynamic mobilization (E, n=6) groups. The group C was treated with neurodynam-ic mobilization, the group D with Jiaji electroacupuncture, and the group D with both 3 days after modeling of clamping at sciatic nerve, while the groups A and B with no treatment. The axon regeneration was observed with HE staining, and the content of BDNF and CNTF in serum was measured with ELISA 4 weeks after treatment. Results The axons regeneration was observed better in the groups C, D and E than in the group B. The content of BDNF and CNTF was more in the groups C, D and E than in the group B (P<0.05). Conclusion Both Ji-aji electroacupuncture and neurodynamic mobilization can improve axon regeneration with synergistic action, which may associate with the increase of BDNF and CNTF in serum.%目的：观察夹脊电针和神经松动术对兔坐骨神经损伤后轴突再生和血清脑源性神经营养因子(BDNF)、睫状神经营养因子(CNTF)含量的影响。方法30只成年雄性兔分为模型组(n=6)、假手术组(n=6)、神经松动术组(n=6)、夹脊电针组(n=6)、夹脊电针结合神经松动术组(n=6)。钳夹法复制坐骨神经损伤模型。模型组、假手术组不做任何干预，神经松动术组行神经松动术治疗，夹脊电针组进行夹脊电针治疗，夹电针结合神经松动术组进行夹脊电针和神经松动术治疗。治疗4周后，HE染色观察轴突生长情况，ELISA法检测血清BDNF、CNTF含量。结果神经松动术组、夹脊电针组、夹脊电针结合神经松动术组轴突生长情况均优于模型组，夹脊电针结合神经松动术组优于神经松动术组和夹脊电针组；神经松动术组、夹脊电针组、夹脊电针结合神经松动术组血清BDNF、CNTF含量均高于模型组(P<0.05)，夹脊电针结合神经松动术组优于神经松动术组和夹脊电针组(P<0.05)。结论神经松动术、夹脊电针均可促进兔损伤坐骨神经的轴突再生，可能与提高血清中CNTF、BDNF水平有关；两者结合效果更佳。
