The results of prediction agree well with the experimental ones. It proves that the thermo-mechanical analysis、the neural network models of flow stress and microstructure as well as the numerical simulation system developed combining coupled thermal-mechanical rigid-viscoplastic FEM with BP neural networks are reliable to describe the hot back extrusion process of Ti15-3 alloy truly. The simulation system has good prediction capacity for the microstructure evolution of Ti-15-3 alloy during hot backward extrusion and after solution treatment. It can be used to replace the experiments for predicting the flowing laws and the distribution of microstructure.

由此证明，本文的热力耦合理论分析、流变应力及显微组织的神经网络预测模型以及采用三维热力耦合刚粘塑性有限元与三层向后传播的人工神经网络相结合的方法开发的Ti-15-3合金筒形件热反挤成形的显微组织数值模拟系统是可靠的，能够真实地描述Ti-15-3合金热反挤工艺过程，并对其反挤成形及固溶处理后的显微组织具有很好的预测能力，可以被用来代替预测其反挤成形规律和组织分布情况的试验。

the manual nn as a highly integrated chiasma subject. most of models about nn are adopting the bp network and the changed form at the practical appliance, which is also the hard core of forward network, incarnating the essential part of nn.

In blastula embryos and 50% epiboly embryos, the zygotic pou2 transcript is also distributed in every blastomere cell. At the stage of 90% epiboly, expression of pou2 converges to the dorsal midline of embryos and locates in two waves of lateral neural plate and two transverse stripes in the brain region. In embryos at 100% epiboly, pou2 transcript is restricted in the neural plate and areas of presumptive midbrain amid himdbrain. From somite stage, gibel carp pou2 can not be detected any more, which is consistent with the RT-PCR result.

在高囊胚期和50%下包期，高度表达的合子转录本仍在所有的胚盘细胞中，但至90%下包期时，pou2的表达向胚胎背部的正中线汇聚，集中在神经板的两侧区域和脑部的两条横向条带在100%下包期时，pou2的表达集中在神经板的中间区域以及预期形成的中后脑区域至体节期时，转录本消失，这与RT-PCR结果高度一致。

Bone marrow mesenchymal stem cells could differentiate into osteoblasts, adipocytes and neural like cells with osteoblast inductor (β-sodium glycerophosphate, dexamethasone, vitamin C), lipoblast inductor (dexamethasone, 3-isobutyl-1-methylxanthine, bovine insulin, indometacin) and serum-free medium inductor (dimethyl sulphoxide, butylated hydroxyanisole) respectively. Osteoblast marker (alkaline phosphatase, osteocalcin mRNA, calcium node), adipocyte marker (lipid droplet, PPAR γ-2mRNA) and neural cell-like marker (nissl body, neuron specific enolase, neurofilament protein) were respectively determined by the immunohistochemical method, polymerase chain reaction and immunocytochemical method.

Gelatin microsphere is firstly made by encapsulating bFGF into gelatin by special manufacture process, then this microsphere was combinated into PLGA conduit or PLGA film.when used, we need only pack the injury peripheral nerve, injury spinal cord, wounded pars encephalic with the PLGA conduit. The conduit or film can slowly release buff which would be absorbed by around tissues.bFGF was already proved to be nutritious to the regeneration and alive of neuron and protect injury neuron.bFGF can also promote morphogenesia and division of nerve cell which would raise the survival rate of neuron, guide the generation of axon etc.bFGF is one of the important factors of sustaining the normal survival of cholinergic nerve.

使用时，只需将此材料贴敷外周损伤神经伤患处，脊髓伤口，或在脑部开颅手术后填充于术后创面，可有效地在伤口局部缓慢地释放并由机体组织吸收bFGF等神经营养因子。bFGF等已被证明具有神经营养作用，可促进神经元的再生与存活，保护受损的神经元。bFGF等对神经细胞兼有促进形态发生与分裂作用，具有提高神经元的成活率、诱导轴突向外生长等功能，是维持前脑基底部胆碱能神经元正常生存的重要因素。
