Though can not accurate induce neural stem cells specific orientation differentiation yet,to accompany the unceasing deepen recognize of convection mechanisms in cells' signal convection and discovery of new cell facter,new chemo-signal, Homo sapiens would solve the question of orientation differentiation from totipotential stem cell,multipotential stem cell to neural stem cell, orientation nerver ancestor cell then special tipe neural cell, implementation functional reconstruction betwen neural cell,for ultimate solve the proble of neural regeneration developing the way.

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 findings of the newly identified goose paramyxovirus strain GPMV/HBexperimental infection were as follows: The challenge caused high morbidity and highmortality.The clinical signs included severe depression, decreased appetite or anorexia,white,yellow and green diarrhea, with neural symptoms;pathological changes showed thathaemorrhage and ulceration of intestine mucosa, necrosis of spleen and pancreas,andedema of liver and kidney, uratic deposition in kidney.Eosinophilic inclusion bodies werefound in the cytoplasm of pancreas and a large quantities of fiber protein were found inintestine. Lots of hemosidefin was found in some area of liver and kidney. A number ofT、B lymphocytes reduced sharply in spleen,lymph nodes in dead geese. Transmissionalelectron microscope showed that some cells had the morphological characteristics ofmitochondria swelling, morphological changes were condensation of nuclear chromatininto dense masses,followed by its marginating against the nuclear envelope, andespecially concentration of cytoplasm association with lots of lipid droplet.

单核／巨噬细胞在类风湿关节炎的发病过程中起着重要的作用。单核／巨噬细胞不仅仅能够产生很多前炎症细胞因子和化学因子，而且它可通过很多机制引起类风湿关节炎的软骨和骨的损伤。

For example, she found that the phytochemicals interfere with the orderly operations of mitochondria, the miniature energy-producing power plants inside cells. Without energy, cells die.

例如，她发现这些化学物质可以影响那些已衰老的细胞的线粒体，失去了线粒体为细胞提供能量的正常功能，这些细胞就会死亡。

The percentage of ERa was approximately 24% in the anterior pituitary gland of adult chicken, and there was no significant difference between laying hens and adult cockerels.

免疫组织化学双标记的结果证明，ERα在成年鸡垂体中所表达的细胞类型主要是LH细胞，而产蛋母鸡中双标记细胞显著高于成年公鸡。

As protein of bacteria and fungi is with negative charge. The antibacterial functional mass, grafted by assembling chemical method, is positive electric polarity. Thus, the antibacterial functional mass is absorbed to the cell of microorganism by the principle of unlike charges attracting. This will influence the normal breath and metabolism of the cell and causes the cell membrane to rupture. In this way, its product realizes the function of being antibacterial, antiviral, and mildew-proof

分子组装抗菌技术主要是通过化学接枝的方法，将精选的抗菌功能团组装到基体树脂的分子链上，利用抗菌功能团的正电性与细菌的带负电蛋白质的异性相吸原理，将微生物细胞吸附，并影响细胞的正常呼吸和代谢功能，造成细胞的破裂，达到抗菌的目的，从而使产品达到了真正意义上的持久抗菌。
