Methods Arterial bypass with prosthesis - graft was carried out in 15 cases: ascending aorta- bilateral axillar arteries and unilateral ICA bypass in 6 cases, ascending aorta - bilateral axillar arteries bypass in 3 cases, ascending aorta - unilateral axillar arteries and unilateral ICA bypass in 5 cases, and in one case of complicated TA combined with abdominal aorta, ascending aorta- bilateral axillar arteries and unilateral ICA bypass were performed, followed by unilateral axilla - femeral bypass.

方法15例重症头臂型大动脉炎患者经胸行人工血管旁路术，升主动脉-双腋动脉、单颈内动脉架桥6例，升主动脉-双腋动脉架桥3例，升主动脉一单腋动脉、单ICA架桥5例，1例合并腹主动脉闭塞的复合型，一期行升主动脉-双腋动脉、单ICA架桥，二期行单侧腋股搭桥术。

Through a study of the cases of transit signaling system improvement in the world, this paper introduces the development of CBTC-MB, which is compared with the traditional Fixed Block, the principle, the functional block diagram and the technical standard of CBTC-MB, holds that this technology will be further developed and applied in urban mass transit.

通过国际上城市轨道交通列车控制系统发行的案例，介绍了移动闭塞在国际上的发展概况。比较了基於通信的列车控制的移动闭塞列车控制方式和传统闭塞方式之间的不同。介绍了移动闭塞的工作原理、组成及相关的技术标准。指出移动闭塞和CBTC必将在城市轨道交通中得到发展和应用。

This research was designed to investigate the efficacy and security of VEGF gene therapy in acute coronary occlusion of animal.

本研究的目的是建立冠状动脉急性闭塞的动物模型，评价血管内皮生长因子基因治疗急性冠状动脉闭塞的有效性和安全性。

The incidence of lower extremity atherosclerotic plaque, arterial steno- sis and obliterlation of type Ⅱ diabetes in old age was apparently higher than that of control group. The incidence of atherosclerotic plaque was mainly involved in femoral and popliteal artery. While the incidence of stenosis and obliterlation were mainly involved in the distal arteries below popliteal artery, especially, anterior tibial artery, posterior tibial artery and pedis dorsal artery.

结果 糖尿病患者下肢动脉血管管腔的硬化斑块、狭窄和闭塞的发生率明显高于对照组；硬化斑块的发生率以股动脉及腘动脉最为常见，而管腔狭窄、闭塞率以及腘动脉以下的远端动脉血管最为明显。

The last two types were mainly distributed at the inferior segment of popliteal artery, the superior segment of anterior and posterior tibial arteries, forming vascular anastomosing network in the whole cnemis muscle group.

晚期的下肢ASO，腘动脉、胫前动脉及胫后动脉虽闭塞，但在某些固定部位仍存在未闭塞的多个侧支，一旦此段主干动脉行内膜剥脱后即可构建远端&侧支流出道&。

In the original studies,[4,5] all the acute stroke patients with angiographically proven internal carotid artery or M1 occlusion had ALN, presumably because the lentiform nucleus is fed by lenticulostriate arteries from M1 without collateral flow from cortical anastomoses.

先前的研究报道：所有经脑血管造影证实存在颈内动脉闭塞或大脑中动脉M1段闭塞的急性卒中患者，都会出现豆状核低信号征；可能系豆状核是由大脑中动脉M1段发出的豆纹动脉供血，缺乏来源于皮层吻合支的侧枝循环供血所致。

The opening of leptomeningeal anastomoses vessel is the important way of collateral circulation in cases of serious stenosis or occlusion of MCA,the collateral flow between MCA and ACA is dominant. The RVACA/RVPCA can reflect the hemodynamic changes、the state of leptomeningeal anastomoses vessel when the MCA was serious stenosis or occlusion; There was a inverse correlation negative correlation between the RVACA/RVPCA and the NIHSS.

⑴在MCA中度以上狭窄或闭塞的情况下，皮质软脑膜吻合血管开放成为侧支循环的主要途径，以MCA-ACA之间的代偿为主；⑵RVACA和RVPCA在一定程度上可以反映MCA狭窄或闭塞时颅内血流动力学的改变、软脑膜侧支吻合的功能状况及有效程度；⑶RVACA和RVPCA与患者的NIHSS评分呈负相关，RVACA和RVPCA值越高的患者，其神经功能缺损程度越轻。

Colur Doppler ultrasonography can display construction of internal carotid artery clearly, detect arteriosclerosis, level of stegnosis and plaque, judge position of interal carotid artery occlusion.

彩色多普勒超声可以清晰显示颈内动脉内结构，检测出动脉硬化、狭窄程度和斑块，能够较为准确判定颈内动脉闭塞的位置，为临床上诊断颈内动脉硬化闭塞症提供一种较为可靠的无创性检测手段。

The time required until occlusion of the venules and the duration of the occlusion were measured.

测量了小静脉闭塞所需要的时间和闭塞的持续期。

Based on an analysis on the present situation and development of three kinds of signal systems (the point system based on interrogator responsor, the quasi moving block system based on digital track circuit and the moving block system based on wireless data transmission) in urban rail transit, some suggestions on the localization of signal system of urban rail transit are put forward.

在分析三种城市轨道交通信号系统制式(基于查询应答器的点式系统、基于数字轨道电路的准移动闭塞和基于无线数据传输的移动闭塞)的现状和发展基础上，对实现我国城市轨道交通信号系统国产化提出建议。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
