| 摘要： |
| 目的：观察运动训练对坐骨神经损伤小鼠神经形态和功能恢复的影响。
方法：雄性昆明小鼠120只，随机分为对照组、假手术组、损伤模型组和损伤后水中运动训练组。采用右侧坐骨神经卡压模型，观察运动训练对小鼠爬网漏脚率、神经传导速度、神经髓鞘计数和神经形态的影响。
结果：运动训练组小鼠术后3周爬网漏脚率明显低于损伤模型组（P<0.01），术后3、4周神经传导速度也明显快于损伤模型组（P<0.01,P<0.05）,神经髓鞘计数明显高于损伤模型组（P<0.01）,电镜下损伤神经得到修复，细胞形态基本恢复正常，明显好于损伤模型组。
结论：运动训练可促进坐骨神经损伤小鼠的神经修复和功能恢复。 |

| Abstract: |
| Objective: To investigate the effect of exercise training on nerval morphology and functional recover of mice with sciatic nerve injury.
Method: One hundred and twenty male Kunming mice were chosen and divided randomly into four groups including control group, sham operation group, model group and training group. Mice right sciatic nerve compression model was employed to observe the effect of exercise training on the rate of foot-slip down from the net, the motor nerve conduction velocity（MNCV）, the number of myelin sheath and the changes of nerval morphologic structure.
Result: Compared with model group, exercise training can reduce the rate of foot-slip down from the net, speed up the MNCV, increase the number of myelin sheaths and improve the nerval morphologic structure（P＜0.05).
Conclusion: Exercise training can enhance nerval restore and functional recover of mice with sciatic nerve injury. |
