At present there is no effective therapeutics to treat PD except the allopathy. The discovery of neural stem cells in the adult mammalian brain provides a new chance to effect a radical cure on PD. But how to make the limited neural stem cells proliferating enough and differentiating into the dopaminergic neurons which can repair the nigrostriatal pathway and help to eliminate the PD symptoms becomes an urgent problem.

成年动物脑内神经干细胞的发现为根治帕金森病提供了新的细胞源泉，但如何使有限的神经干细胞增殖到足够数量并转化为多巴胺能神经元，使之能够修复黑质纹状体通路，逆转帕金森病临床症状，是目前亟待解决的问题。

BACKGROUND: After amyotrophic lateral sclerosis, motor neurons have changes in neural degeneration, but the precise mechanism is not clear.

摘要背景：肌萎缩侧索硬化后运动神经元存在神经变性改变，但其确切机制不明，内源性神经干细胞被认为是未来能有效解决此病的治疗方法之一。

If, on the one hand, neuroimaging studies use a correlational approach which cannot offer a final proof for such claims, available neuropsychological data fail to offer a conclusive demonstration for two main reasons: they use tasks taxing both language and action systems; and they rarely consider the possibility that Broca's aphasics may also be affected by some form of apraxia.

一方面，如果神经影像学研究采用不能提供最终证据的相关性的方法，有效的神经心理学试验数据因下列两个原因未能提供结论性证据：他们过度使用的语言和行为系统；他们很少考虑Broca's失语症患者也可能被某种形式失用影响的可能性。

Then sonorgraphic examination was carried out in 20 patients with cubital tunnel syndrome and 10 patients with carpal tunnel syndrome before operation.Results Not only the structure of cubital and carpal tunnel cauld be showed clearly,but also the cause of the cubital and carpal tunnel syndrome could be distinct.

We conclude that dual and triple injectionof local anesthetic guided by nerve stimulator increases theefficacy of coracoid block when compared with a single-injectiontechnique.

我们得出结论，在神经刺激器指导下两或三次注射局麻药与单次注射相比，能增强臂丛神经阻滞的效果。

The results showed that neural network structure of tobacco aroma components was global optimized, and the neural network trained by genetic algorithm was more efficient and correct than by gradient descent method .

结果表明，使用该方法能全局优化基于烟草致香成分的神经网络结构，较之梯度下降法的神经网络的训练效率更高，得到的识别结果也更加准确。

BACKGROUND: Effective proliferation in vitro of neural stem cells and directional induction and differentiation of dopaminergic neurons play a key role in neural stem cell transplantation for treatment of degeneration of the nervous system and repair of injured nervous system.

背景：在神经干细胞移植治疗神经系统退行性变及修复神经系统功能损伤过程中，有效的神经干细胞体外增殖与多巴胺能神经元的定向诱导分化尤为关键。

ELBE can protect the motor neurons in anterior horn of spinal cord through resisting the change of AchE and ACP.?

结论ELBE能通过缓冲神经损伤后神经元内酶学的变化，起到保护神经元的作用，从而减轻神经元损伤的程度，减少神经元死亡的数量，有利于神经再生。

The spinal radix can be identified according to four factors-terminal filum, the exit of L1 radix on the dura, morphological feature of S1 and S2, and the blood vessel on this region.

根据终丝，L1神经根硬膜出口，S1和S2的形态特征以及节段血管等四个方面综合鉴别能准确辨认神经根。

In this study, the following studies have been carried out(1)Test on a typical MR damper employed in this study was carried out, Neural network model based a direct model and a inverse model were established. The performance of the models were cpmpared with the Bingham model and the hyperbolic tangent model. Results show that ANN model can describe the mechanical behavior of MR damper perfectly as a nonparmetric model.

本文主要进行了以下三个方面的工作：(1)对一种典型的磁流变阻尼器进行了性能试验，利用实验实测数据建立了阻尼器的Bingham模型、双曲正切模型两种参数模型以及基于神经网络的正向和逆向模型，对三种计算模型进行了仿真分析，并与试验结果进行对比研究，结果表明，神经网络模型比两种参数模型能更好地模拟阻尼器的动态性能。
