Objective To observe the effects of urapidil,phentolamine,glyceryl trinitrate or phenylephdrinum on the isolated tracheal smooth muscle in rabbit.Methods KCl,Ach and electrical stimulation were used to induce the contraction of the isolated rabbit tracheal smooth muscle.

目的 观察常用降压药和升压药对气管平滑肌张力的影响，探讨其作用机制方法观察不同浓度乌拉地尔对氯化钾、乙酰胆碱、电脉冲三刺激因素诱发的兔离体气管平滑肌收缩力变化的影响；观察酚妥拉明、去氧肾上腺素和硝酸甘油对电刺激诱发的气管平滑肌收缩力的影响。

The system makes use of cooperation of artificial circuit and digital circuit to produce tristate neural stimulating signal and achieve signal collec-tion and LCD screen real time display of stimulating .

Of all potential fT4-TSH combinations within the current reference ranges were identified as abnormal on the basis of the TSHI.

在进行垂体刺激试验前，促甲状腺激素指数的测定可以很准确的预测垂体刺激试验的失败率(p=0.0002)。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

We also focus on the meta analysis in microarray data of diverse stress on Saccharomyces cerevisiae from different labs to find stress unchangeably expressed genes, and the regulatory elements analyzed by AlignACE tool.

另外，我们还阐述了用meta方法来综合各个实验室的酵母在不同环境刺激条件下芯片数据进行分析，发现一些环境刺激表达基本不变的基因，再用多序列比对识别调控元件工具分析得到一些保守的调控元件。

Methods:Using the model to construct PTSD-like rats. SPS is not performed in the control group and the rest three groups are undisturbedly raised for respectively 24h, 7d and 14d after SPS stimulation. PTSD-like symptoms can be seen in the rats group 7 days after SPS which is the PTSD-like group.

使用SPS方法建立PTSD样大鼠模型，无SPS刺激组为对照组，其余三组分别为SPS刺激后静养24h、7d和14d，其中7d组出现PTSD样症状为PTSD样大鼠组。

The top five negative events accoding to frequency and general strength were housing tension, working and learning pressure, family economic difficulties, unsatisfaction with position and couple separation.

负性事件刺激频度和总刺激强度居前5位的分别是：住房紧张、工作学习中压力大、家庭经济困难、对现职工作不满意和夫妻两地分居。

However,there was no significant difference between the stimulated and unstimulated groups with regard to the phosphorylation of ERK.

与无电刺激组相比，电刺激组OLETF大鼠骨骼肌细胞Akt、AMPK蛋白活性明显增加(P＜0.01)；而ERK蛋白活性无明显改变(P＞0.05)。

It has been shown that chronic stimulation of cultured cardiac myocytes prevents dedifferentiation, maintaining the contractile properties of the cell for much longer than unstimulated cells.

及可同时刺激48个独立的细胞培养皿，每个输出刺激器均可独立设置脉冲特征（程序化电压、频率，持续时间及间隔时间）。

People used to the quick pace of on-line social networking may soon find the real world boring and unstimulating, potentially leading to more extreme behaviour to get that sense.

习惯快节奏的网路社交圈的人们，可能很快就会发现现实世界很无趣、不刺激，这可能导致他们从事更多极端行为来满足刺激感。

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。
