查询词典 cerebral

The contrast material was bolus injected through antecubital vein ,while four layers of dynamic scans were performed for 50 seconds.These slice dynamic images were processed with the CT perfusion software package.Cerebral blood flow,cerebral blood volume,and mean transit time were measured within the specific regions of interest of the brain,and quantitative analysis was performed.

在常规轴面CT扫描后选取基底节及其相邻层面，经肘静脉团注对比剂，同时开始连续50 s的四层动态扫描，重建的198幅动态图像使用CT脑灌注软件包进行处理，获得灌注图像，测量所选脑内感兴趣区的血流量、血容量及平均通过时间，并对其进行定量分析。

It suggests that hypertensive left ventricular hypertrophy and hypertensive arteriolosclerosis in heart and brain may be the same pathological base which causes myocardial infarction complicating with cerebral infarction, and that hypotension is an important inducing factor causing myocardial infarction complicating with cerebral infarction.

提示高血压所致的左心室肥大和心脑小血管的动脉硬化改变可能是心脑梗塞并发的共同病理基础，而低血压则是引起心脑梗塞并发的一个重要诱因。

Blood pressure should be reduced to normal level to prevent heart and cerebral vessels to occur arteriolosclerosiswhen the blood pressure of hypertensive patient is not very highor the duration of illness is short. when blood pressure rises very high or the course of disease is long, blood pressure should be lowered to slightly higher than normal blood pressure level, so it can prevent arteriolosclerosis to be deteriorated further and can prevent the occurence of cerebral ischemia and infarction.

在血压升高幅度不大或起病不久的高血压患者，治疗时应将血压降至正常水平，以预防心脑血管发生动脉硬化；在血压升高幅度大或病程长者，治疗时应将血压降至比正常血压稍高的水平，即要防止动脉硬化进一步加重，也要预防脑缺血和脑梗塞的发生。

These results indicate that the lower blood pressure limit of cerebral blood flow autoregulation is shifted to 10.67kPa in RHRSP because of the hypertensive cerebral arteriolosclerosis which leads to dysfunction of contraction and diastolization of the vessels.

表明RHRSP的CBF自动调节下限上移为10.67 kPa（80mmHg），认为这主要是高血压脑内小动脉硬化血管舒缩功能下降所致。

A formula was designed for regional cerebral blood flow loss index following arteriostenosis when arteriostenosis index formula was deduced; the former may provide a reference to assess cerebral function.

在推导动脉狭窄指数公式中，发现动脉狭窄后局部脑血流量丧失指数的计算方法，试图为评估脑功能提供参考。

As a non-invasive and quick method, 64-slice CT angiography in cerebral and carotid arteries can display clearly cerebral and carotid arterious stenosis,which has a high sensitivity and specificity.

64层螺旋CT头颈血管CTA无创，快捷，简单易行，能够清晰显示颅颈部动脉狭窄性病变，具有较高的敏感性与特异性。

Results: Neonatal rats in hypoxic-ischemicgroup behaved restlessness, cyanosis, deep and rapid breath, astasia, lethargy, irritation and spasm; There were local pyknosis, fragmentation, dissymmetry, blur or disappearance of nucleoli, raritas of ground substance in left cerebral cortex; but there was no statistic significance in chinese traditional medicine group and sham group. The expression of HIF-1α mRNA in brain tissue of experimental group and chinese traditional medicine group were higher than that in sham group, especially chinese traditional medicine group at 3d; HIF-1α positive cells were found in cerebral cortex and hippocampus. There were more HIF-1α positive cells in experimental group and chinese traditional medicine group and mainly in vascular endothelial cells.

结果 缺氧缺血后大鼠相继表现为烦躁不安、全身发给、呼吸加深加快、站立不稳、嗜睡、激惹或间断发作的痉挛和抽搐；HE染色显示实验组大鼠左侧大脑皮层出现局灶性神经元核固缩，核碎裂，核仁偏位，不清或消失，基质疏松；中药组大鼠脑组织结构基本接近假手术组，无明显水肿和坏死表现；实验组和中药组大鼠脑组织HIF-1α mRNA表达较假手术组明显增加，尤其是中药组实验第3日者；免疫组化显示实验组和中药组各时间点大鼠大脑皮层和海马区均可见不同程度的HIF-1α表达，明显高于假手术组，阳性表达主要在血管内皮细胞，海马和皮层的锥体细胞亦有HIF-1α阳性细胞分布。

Carotid atheromatous plaques is closely related to cerebral infarction.One important cause of cerebral infarction is from soft plaque broken in carotid atherosclerosis.

颈动脉粥样硬化与脑梗死的发生有密切关系，颈动脉粥样硬化的不稳定性斑块脱落是造成脑梗死的重要原因之一。

Child cerebral form is the most common form of ALD.Its main clinical characteristics are mental impairment,limbs weakness,alalia,ataxia,seizures,viral and auditive disturbances.Some patients accompanied by visaul nerve atrophy,adrenal cortex and testicle impairment.ALD can be diagnosed by clinical characteristics combined with cerebral MRI.

结论ALD以儿童脑型常见，主要表现为智能下降、肢体无力、言语不清、共济失调、视听力下降及癫发作等症状，可伴有视神经萎缩、肾上腺皮质及睾丸损害，依据临床症状和典型的MRI表现可以进行临床诊断。

The age of onset were 7 to 11 years old.Three patients revealed mental impairment and limbs weakness.Other symptoms included alalia,ataxia in three cases and visual and auditive disturbances in 2 case,One case had visual nerve atrophy and seizures.Testost in one case and 17-hydroxide steroid in another case were degressive.Cerebral biopsy in one case suggest lipide sediment.Testicle impairment in one case was found by ultrasonography.The cerebral magnetic resonance imaging of all the 4 patients showed the characteristic pattern of symmetrical long T1 and long T2 signal in the parieto-occipital region.

结果发病年龄7~11岁，均有智能下降、肢体无力，3例伴言语不清、共济失调，2例伴视听力下降，1例伴视神经萎缩、癫发作，血睾酮降低及血17-羟类固醇降低各1例，B超示双侧睾丸弥漫性病变、脑活检示类脂质沉积病各1例，4例磁共振均见双侧枕顶叶对称性蝶翼状长T1、长T2信号灶，可累及颞叶、内囊和脑干白质。
