BFGF immunoreaction was detected at 3-weeks' embryonic neuroepithelium, and remained positive throughout various development a l stages examined, whereas NGF immunoreaction appeared after 4-weeks. The expres sion varied gradually with the development of embryos. There was no specific EGF immunoreaction in all tissues and stages examined. The occurrence and distribut ion of FGFR, NGFR and EGFR were similar, and their expression altered with the development.

结果显示bFGF和NGF的表达时序不同，b FGF阳性细胞出现较早，在所检测的各个发育阶段均呈阳性表达，而NGF出现较晚，随着胚龄增加，免疫阳性着色逐渐增强，bFGF分布较NGF广泛，而EGF在所检测的各个发育阶段均呈阴性。flg、TrkA、EGFR表达时序和分布相似，三者在所检测的各个发育阶段均呈阳性。

Moutains of evidences from laboratary and clinical data show that gene abnormality is the major etiological factor of over 40% patients affected with epilepsy.There were also 6 epilepsy genes been cloned successfully, and mutations of over 1000 genes maybe related to epilepsy. These abnormal genes influence many aspects from molecular level to the neuronal plasticity, such as the development of brain,neuronic degeneration, remodeling of neural circuits, energy metabolism, ion channel and so on.These factors would at last affect the formation of epilepsy focus, propagations of epileptic potentials, vulnerability of epilepsy cells.

大量的实验和临床资料提示基因异常是40%以上癫痫患者的病因，有6种常见全身癫痫的基因已被成功克隆，1000种以上的基因突变可能与癫痫的发作有关，这些表达异常的基因分布在脑发育、神经元变性及神经环路重组、能量代谢、离子通道等多个环节，从分子、细胞、神经元可塑性等多个方面影响着癫痫灶的形成、痫性放电的扩布及癫痫细胞的损伤，构成了癫痫的基因机制。

During rat's intracerebral hemorrhage processes, Glu is over released and accumulated in hypothalamus and brain tissues surrounding hematoma, which could induce the opening of 〓 and 〓 ion channels, and evoke cellular-toxic edema. Meanwhile it may also evoke 〓 influx into neurons. It is this 〓 influx that may activate phosphase and proteinase, disrupt protein and cellular skeletons, and further aggravate neuronic damage.

大鼠脑出血过程中Glu在下丘脑及血肿周边脑组织的大量释放和积聚，通过其开放〓离子通道，造成细胞毒性水肿，使〓内流激活磷酸酶和蛋白酶，破坏蛋白质和细胞骨架，加重NC的损伤过程。

The high velocity arc spraying technology and powder-cored metal threads were bi-used to repair the waste components, and the integration between coating preparation and materials formation to Fe-Al base intermetallic compounds came true. A new supersonic ion spraying technique, named bi-channel, bi-temperature, was invented to solve successfully the issues of over-melting, half-cooked and burned materials. The high-energy mechanical and chemical method with own property right was explored to solve successfully the issue, which the nano particles dispersed evenly and suspended stably in the solution. After perfecting the techniques the high-performance co-electrodeposition between the conductive matrixes metal Ni and the nonconductive nano particles carried out. The excellent nano anti-friction self-repairing additives was prepared to achieve elementarily the self-repairing on the worn surface during the equipment worked.
