刺激神经

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors.

最终在兴奋性毒性（过度刺激神经元上的递质受体）、钙紊乱、炎症、能量和生长因子缺乏作用下，敏感的神经元发生萎缩、死亡。apoE4与Aβ和tau的异常聚集有关，还可能损伤线粒体和其他细胞骨架。Aβ、tau、apoE和synuclein与其他分子相互作用，影响多种神经活动和存活的信号转导途径。

Ultimately, vulnerable groups of neurons atrophy and die in a process that may involve excitotoxicity (overstimulation of neurotransmitter receptors on neuronal surface membranes), collapse of calcium homeostasis, inflammation, and depletion of energy and growth factors. A form of apolipoprotein E, apoE4, contributes to the abnormal accumulation of A and tau, but probably also damages mitochondria and the cellular cytoskeleton. A , tau, apoE and -synuclein interact with many other molecules and modulate diverse signalling cascades that regulate neuronal activity and survival.

最后，易感神经元会萎缩直至死亡，原因可能有兴奋性中毒（神经递质对神经元表面受体的过度刺激引起），钙稳态失衡，炎症反应，能量和生长因子的耗尽。apoE4的产生可导致A肽和tau蛋白的异常聚合，可能也损害线粒体和细胞骨架。A肽、tau蛋白、apoE和突触核蛋白可与很多分子反应，也可调节不同信号级联反应，这些级联反应对于维持神经元活动性和生存性意义重大。

Enflurane combined with thoracic epidural anesthesia can decrease the sympathetic nervous activity,the balance of sympathetic and parasympathetic nervous activity and the total power of sympathetic and parasympathetic ner-vous system significantly;and it can also decrease the influ-ence of operation stimulation on autonomic nervous function and cardiovascular system significantly.

全麻复合胸段硬膜外阻滞可显著降低交感神经活性、交感/迷走均衡性和植物神经总张力；并显著降低手术刺激对自主神经功能及血流动力学的影响，利于机体血流动力学稳定。

This is because one of the types of autonomic nerves which take effect when you are relaxed, the parasympathetic nerves, have been stimulated by the action of eating.

这是因为，在放松时作用的自律神经之一，也就是「副交感神经」受到「吃」这个动作刺激所导致。

PNS was applied to infraclavicular brachial plexus block for patients in the PNS group while paresthesia positioning method was adopted for those in the control group.

对150例行上肢前臂、腕、手掌、手指手术的患者随机分为神经刺激定位组和传统异感定位组，每组75例。

Paresthesia (a sensation of pricking, tingling, or creeping on the skin having no objective cause and usually associated with injury or irritation of a nerve ), pain, discomfort, and loss of agility may occur.

感觉异常（1 轰动的刺，刺痛，或没有匍匐在皮肤上有客观的原因，通常与相关的伤害或刺激的神经），疼痛，不适，和敏捷性损失可能会发生。

The emission of light from a phosphor after removal of excitation .

大概他的神经天生就很迟钝以至不容有任何刺激的余地。

Pathologic apoptosis can occur in nerve cell under some stimulus, and it can consider to be associated with some kinds of nervous system diseases, such as presenile dementia, ischemic brain damage, nervous degenerative disease, etc.

在一些因素刺激下，神经细胞可发生病理性凋亡，被认为与多种神经系统疾病有关，如神经退行性疾病，早老性痴呆和缺血性脑损伤等。

The results suggest that there are some correlation between the expression of NGF with light stimulation and reproduction.

结果表明神经生长因子的表达，与视觉信息的刺激和生殖状况具有一定的相关性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
