In recent years, rTMS has also been used as a therapeutic tool in a variety of neuropsychiatry disorders such as Parkinson disease and depression that were conceptualized in term of a dysfuction of neuronal circuits and neurons at a cellular and molecular level.
近年来rTMS更是在治疗一系列的神经精神疾患如帕金森病、抑郁等上取得了较好的效果,但其治疗机制尚不明了,而且这些神经精神疾病又被认为是神经环路和神经元在细胞及分子水平上的功能失调,因此探讨rTMS所致的磁刺激对中枢神经系统中神经元基因活性、神经介质或/和调质、结构变化等的调控作用有着重要的意义。

Results:(1)NSCs form typical neurospheres under adequate concentration in vitro, which are immunoreactive to Vimentin. Typically and terminally differentiated mature neural cells could not be found without the stimulus of mitogen or only under NSCs self-regulation and self-induction;(2)NSCs derived from hippocampus maintain the character of stem cells much longer with better biological behavior; NSCs passed to the 2-3 passage are the best to graft since they have not differentiated;(3)NSCs cultured in vitro could self-regulate and differentiate into neurospheres and progenitors positively immunoreactive to specific antibodies representing neurons, astrocytes, oligodendrocytes and Schwann cells;(4)There are widespread synaptic contacts between various kinds of descendent clones and cells;(5)Neurospheres could be formed without the stimulus of mitogen when NSCs and OECs are cocultured. Many neurospheres and cells immunoreactive to Vimentin, GFAP, MAP2, 02, p75NGFR, GFAP, S-100, Synaptosis, Vimentin, Tau (Tau is only positive in cocultureof HNSCs+HOECs) could be found;(6)The supernatant fluid triturated from adult rat spinal cord stimulates NSCs to differentiate into neurons, but do not terminally differentiate;(7)Fibroblasts and O4 oligodendrocytes are not supported to grow under this culture medium.Part II: Isolation, culture and identification of rat and human olfactory ensheathing cellsOlfactory ensheathing cells/glials are the most powerful cells to enable the regeneration of axons in the central nervous system.

Barrington's nucleus that located in the pontine dorsolateral tegmentum is an important site for controlling voiding in the mammalian brain and is often referred to as pontine micturition center. Barrington's nucleus sends direct projection fibers to the sacral parasympathetic nucleus in which parasympathetic preganglionic neurons innervating detrusor muscles of the bladder are distributed. Electron or chemical stimulation of Barrington's nucleus clicits bladder contraction and increases discharges of bladder postganglionic nerve. Conversely, lesion of the nucleus results in a permanent inability to empty the bladder. On the other hand, an area located just ventral to Barrington's nucleu has been reported to send projection fibers to the ventrolateral group of Onuf's nucleus in the caudal lumbar cord segments; the vetrolateral group of Onuf's nucleus is mainly composed of pudendal motor neurons innervating the external urethral sphincter muscle.
Barrington's核发出纤维投射至支配膀胱逼尿肌的骶髓副交感核,毁损该区可导致动物永久性失去排空膀胱的能力;而电刺激或化学刺激该区可引起支配膀胱的节后纤维放电增加和膀胱逼尿肌收缩。D区是紧邻Barrington's核腹侧的一团神经元,它发出纤维投射至腰骶髓Ounf核的腹外侧群,而Ounf核的腹外侧群主要是由支配尿道外括约肌的阴部神经运动神经元组成。

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。
