温针灸对坐骨神经离断大鼠术后功能的影响

Theeffect of warm needling on rat with traversed sciatic nerve repaired by microsurgery

目的评价温针灸对完全离断周围神经显微手术修复后的功能康复作用。方法将大鼠坐骨神经横断,经显微手术缝合后在电针基础上加入温针灸疗法,观察术后4、8、12周大鼠坐骨神经功能指数(SFI)变化,测定术后12周运动神经传导速度(MNCV)。结果术后4周温针组SFI与模型组和单纯电针组相比均明显改善(P<0.01);术后8周温针组SFI明显优于模型组,差异具有统计学意义(P<0.01),与单纯电针组相比差异无统计学意义(P>0.05);术后12周,温针组和单纯电针组均明显优于模型组,差异非常显著(P<0.01),但两组组间比较,温针组SFI及MNCV虽优于单纯电针组,但差异无统计学意义(P>0.05)。结论温针灸对离断坐骨神经的术后功能恢复具有一定作用,有待进一步实验加以证实。

Objective To evaluate the effect of warm needling on completely amputating peripheral nerve repaired by microsurgery. Methods SD rats with traversed sciatic nerve that repaired by microsurgery were treated by both warm needling and electroacupuncture. Sciatic function index（ SFI） of 4,8,12 weeks after operation and motor nerve conductive velocity（ MNCV） of 12 weeks after operation were observed,and compared these data of normal group,model group and electroacupuncture group. Results 4 weeks after operation,compared with model group and electroacupuncture group,SFI of warm needling group improved significantly（ P0.01）. 8weeks after operation,SFI of warm needling group was still better than model group（ P0.01）,but significant difference between warm needling group and electroacupuncture group was not found（ P 0. 05）. 12 weeks after operation,compared with model group,SFI,MNCV of warm needling group and electroacupuncture group both improved（ P 0.01）,but statistical significant difference were not found between these two groups（ P0.05）. Conclusion The effect of warm needling on completely amputating peripheral nerve repaired by microsurgery is obvious,but it is necessary to do a further study.
