The sacral plexus was identified at the levelof the sciatic foramen as a round hyperechoic structure.

The lesion, the changes of activity of cholinesterase and acid phosphatase of motor neurons in lateral nucleus of spinal cord anterior horn, the function of axoplasm transportation and nerve conduction, the regeneration of axons and myelin sheath, and the recovery of sciatic nerve function were examined at 7, 14, 30 and 90 days intervals after operation, using Nissl and enzyme histochemistry staining, electrophysiological technique, hydrogen-peroxide oxidoreductase retrograde trace method, axon image analysis, and measurement of sciatic function index. The spinal cord anterior horn of injury side was compared to the correspondence region of spinal cord.

分别于术后7、14、30和90d应用酶组织化学方法、电生理方法、HRP （hydrogen-peroxide oxidoreductase）逆行示踪方法、轴突图象分析方法以及坐骨神经功能指数（sciatic nerve function index，SFI）测量等方法检测坐骨神经损伤后对应脊髓神经元的存活率、神经元胞体酶系变化、损伤神经在轴浆运输、电传导以及轴突、髓鞘再生等方面的恢复情况，探索外周神经损伤后OECs及几丁质对神经元的保护作用以及对新生神经功能恢复的作用，为外周神经损伤的治疗提供新的理论基础。

4DRG was co-culture with sciatic nerve segment in 10%FBS+DMEM; the axons were longer and surround the sciatic nerve segment which was regard as a new evidence for chemotropism.

4有血清条件下联合培养，观察到神经元的轴突环绕坐骨神经段生长，呈现诱导现象，并且能够促使轴突长度明显增长。

4DRG was co-culture with sciatic nerve segment in 10鸖 DMEM;the axons were longer and surround the sciatic nerve segment which was regard as anew evidence for chemotropism.

结果：(1)在无血清条件下单独培养的DRG，背根神经节的轴突数目众多，外形纤细弯曲，不成束，并且施万细胞和成纤维细胞稀少，所以可以排除两者对轴突生长的影响，为观察来源于变性坐骨神经段的可溶性因子对轴突生长的作用提供了有利条件；(2)在无血清条件下DRG和变性坐骨神经段联合培养，①先单独培养DRG，4天后待神经元轴突长出，再与坐骨神经段联合培养，观察到神经元的轴突数目减少，外形挺直，部分轴突之间相互粘附成束；②变性坐骨神经段和DRG同时联合培养，神经元的轴突数目明显减少，外形粗壮，轴突之间相互粘附成束；(3)有血清条件下单独培养DRG，轴突数目较多，外形挺直，长短不一，部分神经元的轴突之间相互粘附，施万细胞和成纤维细胞数目众多，观察到的轴突生长情况受到施万细胞和成纤维细胞的直接或者间接的影响。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
