Objective To study the effect of dexamethasone on the recovery of motor neuron in anterior horn of spinal cord following sciatic nerve injury.

目的 观察地塞米松对大鼠坐骨神经损伤后脊髓运动神经元形态学的影响。

By 14 days after operation, the expression of GAP -43 mRNA was evidently up -regulated compared with control group.

用免疫组化方法检测术后1、3、7、14d脊髓前角GAP-43免疫阳性运动神经元的表达。

The condition of rats' palp movement and nerve condition velocity were observed.

结果：面神经损伤后第7d、14d、21d和28d时间段，对照组面神经运动神经元的存活率分别为93.06%、76.06%、72.38%和70.69%，转染组分别为94.00%、84.00%、79.25%和78.06%。

The ultrastructure studies show that the number of mitochondria in the motor neurons from resistant strain are higher than those of the susceptible strain, and the thickness of neural lamella and perineurium of resistant strain is thicker than those of the susceptible insects.

棉铃虫抗性种群、对照种群、同种群不同龄期幼虫以及同一个体胸、腹神经节的神经细胞体外培养时形态无明显差异，但抗性品系幼虫运动神经元内线粒体明显增多，且神经围鞘与神经节膜厚度之比明显增加。

RESULTS: The positive staining cells mostly included ependymal cells of myelocoele, glial cells, motor neurons, and epithelial cells of spinal pia mater. The staining was mainly located on the cell membrane. Most importantly, it displayed certain directivity in the glial cells, mainly at the membrane side contacting with capillary endothelial cells.

结果： 免疫组织化学染色结果显示阳性着色细胞包括有胶质细胞、中央管室管膜上皮细胞、脊髓前角运动神经元、软脊膜上皮细胞，着色部位主要在细胞膜，其中在胶质细胞表现出一定的方向性，主要分布在与毛细血管内皮细胞接触的一侧。

Results: the positive cells mostly included ependymal cells of myelocoele, glial cells, anterior horn motor neurons, and epithelial cells of spinal pia mater and their expressions were mainly located on cell membrane. interestingly, aqp4 distribution in glial cells and ependymal cells showed certain directivity, but the former was mainly in the membrane side contacting with capillary endothelial cells and the latter mostly in the basolateral membrane of ependymal cells.

结果： 免疫组织化学染色和原位杂交结果显示胶质细胞、前角运动神经元、中央管室管膜细胞、软脊膜上皮细胞均表达阳性，aqp4主要分布于细胞膜，其中，胶质细胞和中央管室管膜细胞表达存在极性，前者主要分布在与毛细血管内皮细胞接触的一侧，后者主要分布在中央管室管膜细胞的基底侧膜。

Secondly, the athletes should adopt the vibration training method or the strength training method with unstable supporting surface.Because these two methods can not only activate motion element which couldn\'t be activated in most of time,but also add up the harmonization of the nerve muscle and make the proprioceptor trained.Thirdly,we should make or choose special archery shoes which have slip-resistant sole and suitable degree of bend in the front and back,suiting for the competition ground and adding Up the stability,fourthly,we should properly pay attention to the stage of lifting.

因为这两种训练方法不仅可激活多数情况下不能激活的运动神经元使力量增加，而且可增加神经肌肉的协调性，同时也使本体感受器得到训练，从而增强对射箭动作的感觉能力；第三，为射箭运动员定制或选择有防滑块鞋底、前后上翘程度符合运动员脚型特点的射箭专用鞋，既可以适合比赛地面特点又能增加稳定性；第四，适当重视举弓阶段的训练。

Objective: To investigate an effect of spasticity due to upper motor neurone injury by robot-aided training and explore its mechanism.

目的为观察机器人辅助训练对上运动神经元损伤所致上肢痉挛的疗效并探讨其机制。

So the theory of the correlation of spleen and kidney can effectually guide the treatment on MND.

结论中医脾肾相关理论对运动神经元疾病的诊疗有较高的指导价值。

To E8 embryonic day, the expression was mainly in the ventral horn, especially in the motor neurons.

到了ES期，它的表达主要集中在前角运动神经元，而其它部位的信号明显较弱。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
