Methods and Materials:Sixteen healthy young college students without requiring medical service for lower limb due to injury in past 6 months accept 8 weeks plyometric exercise training. Using nerve conduction velocity test, surface electromyography, isometric dynamometer, electrogoniometer and ultrasonography to detect the change of (1)muscle activation level.(2)number of α-motorneuron.(3)nerve conduction velocity. And the mechanical properties of muscle-tendon complex are including (1)fascicle length.(2)fascicle angle.(3)fascicle curvature in muscle(4)muscle composition and (1)stiffness (2)hysterisis in tendon and electromechanical delay are also analysis.

材料与方法：16位下肢在六个月内没有因为受伤而接受任何医疗协助的，接受8周增强式训练前后，接受使用神经传导检查，表面肌电图，等长肌力测力仪，电子量角器以及高频影像超音波等工具之量测，以了解肌肉活性改变包括(1)肌肉适应情形(2)神经元的改变(3)神经传导速率的变化以及肌肉肌腱复合体的机械特性，包括肌肉(1)肌束长度(2)肌束与深层腱鞘的角度(3)肌束弯曲度(4)肌肉组成，以及肌腱腱鞘复合体的(1)刚性与(2)迟滞现象以及机电传导延迟时间。

Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。

We use ANN method to predict employment.The research method of the modem economics has two kinds, empirical research method and the norm research method. We use the two methods to analyze this problem, and want to find the law of them, but my featherhead and litter knowledge limit the effect.

就作者自身的知识和了解，本文可能存在以下创新：(1)首先判断了中国的工资和就业量是存在结构突变的一阶单位根过程；(2)考虑到存在结构突变的情形，中国经济增长与就业之间存在双向的因果关系；(3)对消费和投资对就业的作用进行考察，指出了政府消费和投资对就业无作用，农村消费对就业有重大的作用；(4)在对未来的就业需求的预测上，本文使用神经元网络方法对其进行预测。

The most sensitive period of alcohol damage is during the brain growth spurt, the last trimenon of mankind fetation and the first two postnatal weeks in the rat.

研究发现酒精损伤的作用最敏感的时期正是脑生长发芽期，在人类为孕后三个月(相当于大鼠新生至生后两周)，在这个时期，短暂的酒精接触便会使皮质、海马、小脑的上百万神经元损害。

the increase of lhx8 mrna expression after fimbria fornix transected might be related to the regeneration mechanism of differentiation of neural stem cells into cholinergic neurons in hippocampus.

切割穹窿海马伞后海马中lhx8 mrna表达的增高可能与神经干细胞向胆碱能神经元分化的再生机制有关。

Methods: We transplanted neural stem cells from embryobrain of rats in hippocampi of AD model rats transecting fimbria fornix with or without FG.
