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。

The result indicated that the virus has been one of the important pathogens of nonbacterial prostatitis. PCR detection of viral prostatitis was highly specific and should be of value for the evaluation of drug therapy.
