动脉

Previous findings from our laboratory have demonstrated that simulated weightlessness may result in atrophic changes with depressed vasoconstrictor responsiveness in hindquarter vessels, and hypertrophic changes with enhanced vasoconstrictor responsiveness in cerebral arteries of rats.

动物实验结果已证实，模拟失重可使大鼠不同部位动脉血管发生差异性改变：后身动脉血管发生萎缩性改变和收缩反应性降低；而脑部血管则发生肥厚性改变和收缩反应性增强。

Among 18 cases of diabetes complicated with hyperpiesia, 13 cases had arteria carotis atherogenesis, and its incidence was 72%; Among 6 cases of diabetes, 2 cases had arteria carotis atherogenesis, and its incidence was 33%.

高血压、脑血管病、糖尿病患者多继发颈动脉粥样硬化斑块；利用彩色多普勒超声能准确有效的评价颈动脉病变的程度；为有效的预防和治疗老年血管性病变提供依据，具有十分重要的意义。

Atherosclerotic plaque can be found in most hyperpiesia, cerebral vessels and diabetes diseases; Arteria carotis diseases can be evaluated exactly by Color Doppler ultrasound, which effectively supports the prevention and treatment of peripheral vascular diseases.

高血压、脑血管并糖尿病患者多继发颈动脉粥样硬化斑块；利用彩色多普勒超声能准确有效的评价颈动脉病变的程度；为有效的预防和治疗老年血管性病变提供依据，具有十分重要的意义。

Methods Thirty adult male New Zealand rabbits were made into models of double hypogastrium superficial epigastric artery skin flaps and were randomly divided into three groups:aterial interruption group,venous interruption group,and total vascular interruption group.

30 只新西兰兔制作双侧下腹部腹壁浅动脉皮瓣模型，随机分为3组：动脉阻断组，静脉阻断组，动静脉阻断组。

MR angiograms of 204 cases were analyzed retrospectively to sum up the variation ratios of cerebral arteries, their differences in gender and sides, in which the artery not displayed was regarded as absence and the artery 1/2 diameter less than the symmetrical one was regard as hypogenesis.

三、回顾分析204例正常3D-TOF技术MRA三维图象，以MRA未显示为缺如，以成对动脉中一侧直径小于对侧1/2为发育不良，分别统计各动脉的各种变异率，并统计分析其性别及左右侧差异性。

Result The CTA of vertebral artery can find all kinds of abnormal ,example hypogenesis stenosis,formation of atheroselerotie plaque and calcification,and press by surrounding tissue, and affect the blood stream of vertebral artery directly.

结论椎动脉CTA可以发现椎动脉的先天狭窄、管壁内粥样斑块形成及其钙化，以及受周围组织挤压，均能引起TIA。

It was suggested that structure changes such as incurvation and stenosis of the vertebral artery caused by spondylopathy were reasons of cervical vertigo.

结果表明，颈椎病所致的椎动脉弯曲、狭窄等结构改变是引起颈性眩晕的主要原因，而转颈时椎动脉的上述改变明显加重。

So for the moment, we recommended in the newguideline that to measure pulse wave velocity, carotid artery pulse wave velocity which means arterial stiffness, because we have good evidence that it is an independent predictive value for cardiovascular events.

所以目前，我们在新的指南中推荐测量脉搏波速度，测量颈动脉的脉搏波速度，这个指标就是代表动脉僵硬度，因为我们有很充分的证据证明它对心血管事件有独立预示价值。

Methods CT findings of 53 cases with acute cerebral infarct of middle cerebral artery were analyzed retrospectively.

方法回顾分析 53例大脑中动脉分布区急性脑梗死CT脑动脉高密度征的影像资料。

During chemotherapy both systolic maximum and diastolic minimum blood flow velocity and resistance index in renal segmental artery and interlobular artery were meaured by color doppler weekly.

于化疗中每周应用彩色多普勒超声仪监测患者肾脏血流，测定肾脏中心区域的区域动脉、叶间动脉的血流速度波形，求得收缩期最高血流速度，扩张期最低血流速度及阻力指数。

And discuss some key point of integrated management system design, include hazard identification and risk assessment and risk control in the occupational health and safety management, the measure of satisfaction target of customer, the flawlessness of law system, the integration of the integrated management system and enterprise standardization system, unify lead institution and work orgnization, integreted internal audit and integrated management review.

同时，论述了一体化管理体系构建中的几个主要问题，包括职业健康安全管理中的危险源辨识、风险评价和风险控制、顾客满意度的科学监测、法律、法规体系的完善、一体化管理体系与企业标准化体系的有机结合、统一的领导机构和工作机构、一体化的内部审核和管理评审。

Deepwater Taranaki is investigated for its petroleum potential, using all available seismic data tied to shallow-water wells.
