The course will start with an overview of the central and peripheral nervous systems, the development of their structure and major divisions. The major functional components of the CNS will then be reviewed individually. Topography, functional distribution of nerve cell bodies, ascending and descending tracts in the spinal cord. Brainstem organization and functional components, including cranial nerve nuclei, ascending / descending pathways, amine-containing cells, structure and information flow in the cerebellar and vestibular systems. Distribution of the cranial nerves, resolution of their skeletal and branchial arch components. Functional divisions of the Diencephalon and Telencephalon. The course will then continue with how these various CNS pieces and parts work together.

The result showed that IFN-γ was distributed over 20 nucleus of the hypothalamus, such as nucleus mamillaris medialis, nucleus pre-opticus medialis, area anterior hypothalami, nucleus ventromedialis, nucleus reunions, nucleus paraventricularis, nucleus supra optic, and etc. Many of IFN-γ positive nerve fibers were found in supra optic nucleus, paraventricular nucleus, nucleus mamillaris medialis and etc. Nerve fibers and astrocytes IFN-γ immunoreactive positive cells spreaded in paraventricular nucleus, nucleus pre-opticus lateralis, nucleus pre-opticus medialis and etc. At the same time, IFN-γ is also observed obviously in adenohypophysis and neurohypophysis. IFN-γ also expresses in follicular and corpus luteum.

It may have a preventional function from Alzheimer's disease. Molecular biological studies are shown that apoE isoform has a isoform-specific role to neurodegeneration. ApoE〓 and apoE〓 aid to sustain the stabilization of cytoskeleton protein tau, while apoE〓 hyperphosphorylates tau to destabilize the microtubule protein, which will make neurocyte easy to form neurofibrillary tangles in AD. Clearance of amyloidal peptide by apoE〓 and apoE〓 is more effective than by apoE〓. ApoE〓 has the strongest ability to clear the amyloidal peptide. It is shown that apoE〓 has a stronger prevention from Alzheimer's disease.

分子生物学研究发现，apoE异构体对神经细胞退化表现出异构体特异作用，apoE〓和apoE〓有助于维持微管的稳定性，而apoE〓则使tau蛋白超磷酸化，破坏微管的稳定性，使神经细胞易于形成神经纤维缠结。apoE〓和apoE〓对A β的清除率远远高于apoE〓，apoE〓对A β的清除能力最强，可见apoE〓对AD的发生具有较强的阻止作用。

N perifocal tissue intracerebral hemorrhage there were rarefaction neuron,cell spaces augmentation,cell diminution,distinct demarcation of cell membrane and surrounding,and we discovered a lot of degeneration and necrosis nerve cells,cell body collapsed,pycnosis anachromasis,nucleoli disappeared. In EPO group we discovered that center area of hemorrhage shinked,nerve cells of degeneration and necrosis decreased in perifocal tissue,majority cells morphous were normal and pathological changes were light.
