METHODS: NSCs were isolated from neonatal rats by enzyme digestion and mechanical separation. At the fourth passage, cell clone masses received nestin immunocytochemistry. Remaining cells were dispersed by mechanical separation. Monoclone NSCs were incubated by limiting dilution assay, and made into 108 L-1 monoplast suspension in complete medium. NSCs were assigned into 2 groups. NSCs in the control group were incubated in 10% fetal bovine serum.

Cephalomappa sinensis is a monotypic genus ever-green tree endemic to the calcareous mountainous region in southwest of Guangxi Zhuang Autonomous fresh branches are used as feeding stuff for cattle,horse,sheep,and can make them find the possibility of developing feed additive or medicine for livestock,the chemical constituents from this plant were chemical constituents of its roots had been reported in our earlier continuation of our investigation on the branches of Cephalomappa sinensis,a new norneolignan,named Ceplignan(1),was isolated from ethanol extract through column structure was elucidated on the basis of spectroscopic evidence.

肥牛木(或称肥牛树，Cephalomappa sinensis)为大戟科一单种属植物，为常绿乔木，其分布区狭窄，仅限于广西西南部石灰岩山地[1]。肥牛木为优良木本饲料树种，是牛、马和羊的好饲料，用该植物饲养牛，可使牛肥壮，故有肥牛木的名称[1]。研究其化学成分，目的在于探讨开发饲料添加剂或兽药的可能性。我们曾报道了肥牛木根的化学成分[2，3]，在对其枝条的进一步研究中，又分离得到一个新的降新木脂素，命名为肥牛木素。本文报道其分离方法和结构鉴定结果。

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。
