The results suggested that AC-cAMP-PDE pathway in cerebellum did not participate in regulating the anesthetic action, but perhaps correlated with ethological changes (such as behavior mis match and orientating function handicapped) during recovery period.

4临床相关剂量的噻拉唑和QFM合剂对大鼠大脑皮质、海马、脑干和小脑的PDE活性无影响，结果说明，大脑皮质、海马、脑干和小脑AC-cAMP-PDE信息传递系统对噻拉唑和QFM合剂麻醉作用的调控不是通过PDE对cAMP的降解作用，而是通过其它途径（如通过调节AC的活性影响cAMP的生成环节）来调控cAMP的产量实现的。

Objective To evalue the protective effect of propofol against cerebral ischemia-reperfusion injury in patients with acute cerebral infarction.

目的 探讨异丙酚对急性脑梗塞患者脑缺血再灌注损伤的保护作用。

NMDA receptors are a subclass of excitatory amino acid receptors which play an important role in brain development, learning and memory processes.

NMDA受体是一种兴奋性氨基酸受体，在脑的发育、学习与记忆、脑缺血等机制中起重要作用。

With the increase of excitory amino acids after cebral ischemia, the concentration of inhibitory acids such as γ-amino acid has been also increased to resist the toxicity of the excitory amino acids .

研究发现脑缺血后，伴随着兴奋性氨基酸的释放增加，脑内抑制性氨基酸如γ-氨基丁酸的浓度也升高，以拮抗兴奋性氨基酸的毒性作用。

The synthetic and release of excitory amino acids are greatly increased after cerebral ischemia and the balance btween excitory amino acids and inhibitory acids are broken.

脑缺血性损伤时，脑内兴奋性氨基酸的合成、释放明显增加，兴奋性/抑制性氨基酸的动态平衡被打破。

The extracerebral CCM group,completely different from the intracerebral one, presented elastic and thick-wall vessel.

脑外组CCM表现为弹性较好的厚壁血管，脑内组为弹性较差的薄壁血管。

Methods The clinical and CT, MRI, DSA imaging data of 57 eases of cerebral CA were collected and studied. All cases were proved by surgical and pathologic findings. Among the cases, 48 were intracerebral CA and 9 were extracerebral CA.

对57例经手术病理证实的脑CA的临床和CT、MRI及DSA影像学资料进行分析，其中脑内型CA 48例，脑外型CA 9例。

Arachnoid cysts are extracerebral, intra-arachnoidal cerebrospinal fluid collections that are most commonly found in the middle cranial fossa (50%).

蛛网膜囊肿是一种脑外，蛛网膜腔内的脑脊液聚集。最常见于中颅窝

Results:MRI demonstrated that cerebral metastases were mainly from extracerebral organs(91.8%); multifocal metastasis occurred more frequently(57.1%);the cerebral parenchyma was the most common site of cerebral metastasis(87.8%),the following was the sk...

结果 ：MRI显示脑转移瘤主要为外源性，占 91.8%；多发性较常见，占 5 7.1%；转移部位多为脑实质( 87.8%)，其次为颅骨( 6 。1%)、软脑膜( 4 。1%)、幕下( 2 。0 %)转移；大多数转移瘤的MRI表现为类圆形长T1 长T2 信号肿块，实性部分多数均匀增强。

OBJECTIVE: To study the characteristics of extracranial artery structure and hemodynamicchanges in patients with cerebral infarction and make a comparison of these with those of the normal people.

目的：研究脑梗死患者颅外段脑动脉血管结构和血流动力学变化特点，并与健康人进行差异比较。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
