尽管目前尚不能准确有效的诱导神经干细胞特异性定向分化为某种特定的神经元，但随着人们对细胞间信号传递机制认识的不断加深和新的细胞因子、化学信号的不断发现，人类将能够解决从全能干细胞、多能干细胞到神经干细胞、定向神经祖细胞直至特异类型神经细胞的定向分化，完成神经元之间的功能重建，为最终解决中枢神经再生这一难题而开辟道路。

The figure of SFI showed that the functional recovery in the experimental groups was better than that of the control at every 10 days after sciatic nerve transection.

因此，OECs和几丁质对外周神经损伤所导致的脊髓神经元死亡和退行性变有较好的保护作用，对外周神经损伤后新生神经功能的恢复具有积极的促进作用。

The experimental study of dog sacral nerve distribution and its influence on lower urinary tract function:For further understanding of the distribution of dog sacral nerve in bladder, urinea and penis, and in order to set up theoretical basis for selective sacral nerve rhizotomy in treating spastic bladder after spinal cord injury, 12 dogs were respectively given electrical stimulation to S 1 3 nerve roots and the contraction of musculus sphincter urethrae and detrusor urinae, the change of bladder pressure and penis erection were examined and recorded.

犬肪神经对下尿路的支曰及功能影响的实验研究：为进一步明确犬骰神经对膀耽、尿道及阴茎的支配情况，并为选择性骰神经根切断治疗脊髓损伤后痉挛性膀眈寻找理论依据，我们电刺激12条家犬的S；－／经根，通过尿流动力学检查及电生理检测来观察其逼尿肌、括约肌的收缩及阴茎勃起情况。

Significance:(1)The phenomenon that soluble proteins coming from sciatic nerve segment under going Wallerian degeneration make axonal number of the dorsal root ganglia decrease and axons adhere to each other are first observed in our essay.

变性神经段中可溶性因子能够促进神经元轴突的生长、轴突直径增加；通过形成浓度梯度诱导轴突生长的方向、减少背根神经节再生轴突数目和使背根神经节轴突之间相互粘附。

According to these features, a hybrid genetic algorithm is developed to optimize the operation of pulverized system in admixing combustion conditions, where a fuzzy neural network is adopted to evaluate admixed coal's slag property, and a radial basic function neural network is used to predict pulverized coal's fineness and mill's outlet temperature.

本文将人工神经网络和遗传算法相结合形成混合优化算法，对电站多煤种掺烧制粉系统运行进行寻优。针对掺烧煤结焦的模糊性和非线性特征，采用模糊神经网络评估混煤的结焦特性，并利用径向基神经网络关联掺烧煤的煤粉细度和磨出口温度。
