GFP expression started during gastrulation in the axial hypoblast layer. During segmentation, GFP was detected in the notochord but not in the foor plate.

GFP在原肠作用期就开始表达，主要发生在中轴下胚层中；在体节形成期，GFP在脊索细胞中表达，但未发现在神经底板细胞中表达。

An enriched PCR fragments with less complexity were obtained and mainly expressed in the denervated hippoampus After cloning into the plasmid vector, 46 clones were initially screened and subjected to autosequencing By comparison with the EMBO gene databases, 21 gene fragments of different types were obtained with 11 similar to genes of known function and 10 similar to ones of unknown function It is inferable that the altered gene expressions of hippocampus following the entorhinally denervation may underlie the specfic reinnervation and the formation of synapses by transplanted entorhinal neurons with host neuropil within the denervated target areas.

初步挑选出的46个转化后的阳性克隆，经点杂交筛选和基因序列分析，与Gene Database同源性比较后，得到21种基因片段，其中功能已知的有11种，功能未知的有10种。结果表明海马在去内嗅皮层后某些基因表达的改变，这可能是移植胚胎内嗅皮层神经细胞轴突特异支配去神经靶区和重建突触联系有关。

脊索细胞构成的一条纵长可弯曲的杆状结构，其作用是引导产生神经板，形成躯体的支持轴

In order to control the flow separation by reducing the diffusion factor and enlarging the diameter of inner circle, the meridian plane profile of the return channel was redesigned, which is achieved by substituting arbitrary curve for the circle with no change of the axial length of the stage. Bezier curve with eight parameters was chose to describe the shape of meridian plane profile, and the optimization of the meridian plane profile was implemented combining back-propagation neural network with genetic algorithm.

改进的主要思路是减小弯道前半部分通道的扩压度，并同时加大弯道出口内侧的转弯半径，主要做法是在不增加整级轴向尺寸的前提下，用任意曲线取代传统弯道的同心圆环结构，给定弯道回流器子午型线的外侧型线，采用Bezier曲线对内侧型线的2段曲线进行参数化描述，利用遗传算法和反向传播(back-propagation，BP)神经网络相结合的方法对内侧型线进行优化，得到新的弯道回流器子午型线。

Out of 9 animals with hearing loss had these autoantibodies; Endolymphatic hydrops, vasculitis of modiolus, degeneration of the neural elements, distension and thicking of the Reissner's membrane were seen in 46%, 78%, 12%, 21% of the experimental group ears respectively.

实验组32耳中内淋巴积水、蜗轴血管炎、螺旋神经节细胞空泡变性肿胀，前庭膜增厚、折叠的发生率分别是46%、78%、12%、21%，听力损害的12耳均有不同程度的上述病理变化。

It is believed that the dysfunctions of monoamine nerve in central nervous system and HPA axis are responsible for depression.

目前认为，中枢单胺神经和下丘脑-垂体-肾上腺轴功能异常可能是抑郁症发病的主要生物学原因，以此理论支持的抗抑郁药物虽有较好的疗效，但仍然对近30％的抑郁症患者无效。

The thickness of myelin sheath of experimental group was inferior to that of group B (P.05) at the third month, while the number and diameter of axons in both groups was similar.

这种无细胞基膜管移植体能支持轴突的生长和雪旺细胞的迁移，是一种良好的神经移植替代材料。

So, we speculate that amelioration of axonal myelination after SCI will be favorable for the functional recovery of the injured spinal cord.

因此，我们推测改善脊髓损伤后轴突髓鞘化可有助于损伤脊髓神经功能的恢复。

Nerve cell The body of a neuron without its axon and dendrites.

Administration of NGF may treat the spinal cord and periphery nerve injured and improve the function of damage nerve.

神经生长因子是最先发现和被证实的细胞生长调节因子，NGF在神经细胞的增殖，分裂和轴突的生长、递质的合成及细胞的凋亡等阶段均起着重要作用，NGF对中枢和周围神经的损伤均有保护和促进恢复的作用，尤其是NGF促进神经细胞的再生，给予NGF可减轻和改善对神经元的损害和治疗外伤引起的脊髓和周围神经损伤。
