狭窄

Between 6th and 14th weeks afteconstricted bilateral renal arteries, the blood pressure in the majority of RHRSP with cerebral infarction was obviously higher than in RHRSP without cerebral infarction (28. 8±2. 24kPa～32. 3 ±2. 88kPa, 26. 2±2. 01～28. 3±2. 33kPa respectively). Severe hyalinosis, fibrosis, wall hypertrophy, lumen stenosis, and even microaneurysm formation in cerebral small arteries in RHRSP with cerebral infarction were found, while slight to mild arteriolosclerosis in RHRSP was found without cerebral infarction.

本实验发现，RHRSP在经受不同水平的低血压后，产生脑梗塞的大多数（32/38只）在肾动脉狭窄术后第六周至第十四周，血压为28.8±2.24 kPa～32.3±2.88 kPa（216±17mmHg～242±22mmHg），显著高于无脑梗塞的RHRSP，并且发现这些RHRSP的脑内小血管呈严重的透明样变、纤维素样变性，管壁增厚，管腔狭窄，部分有微动脉瘤形成；而无脑梗塞的RHRSP的血压为26.2±2.01kPa～28.3±2.33 kPa（200±15mmHg～212±17.5mmHg），其脑内小血管呈轻至中度的动脉硬化改变。

objective to evaluate dsa and percutaneous transluminal renal arterioplasty for the treatment of renovascular hypertension.methods 82 suspected patients with renovascular hypertension were given dsa examination.28 patients were treated by means of ptra while another 5 cases with unilateral kidney atrophy treated surgically.results 49 patients were normal,33 patients were abnormal,28 patients were treated by means of ptra.blood pressure had got to normal in 10 patients while in 13 patients bp dropped noticeably after ptra.the overall benefit rate was 82.1%.conclusion dsa and ptra are clinically effective for the treatment of renovascular hypertension.ptra is technically successful.

目的 评价经皮腔内肾动脉成形术治疗肾血管性高血压的价值。方法 82例全部行dsa检查，肾血管狭窄者行ptra术或外科手术，观察其治疗效果。结果 82例患者行肾动脉造影后血管正常者49例，异常者33例，其中单侧肾萎缩5例行外科手术（肾动脉搭桥1例），肾动脉狭窄28例行经皮腔内肾动脉成形术（血管内支架5例），术后10例血压降至正常或基本正常，13例血压得到改善，5例无效，总有效率达82.1%。结论 dsa检查和ptra术在诊断和治疗肾血管性高血压方面有明显的临床价值。高血压，肾血管性；数字减影血管造影术；经皮腔内肾动脉成形术

Objective To investigate the distribution of intracranial or extracranial arteriostenosis in patients with transient ischemic attack, and analyze the correlation between distribution of arteriostenosis and prognosis.

目的 观察短暂性脑缺血发作患者颅内外动脉狭窄的分布情况，评价颅内外动脉狭窄的分布与预后的关系。

Recently, with developing of balloon and stent compliance, as well as stent technology, and application of various novel materials and cerebral protection device, stent has become a safe and effective therapy for intracranial arteriostenosis.

近年来，随着球囊和支架柔顺性的改进及支架技术的发展，各种新型材料及脑保护伞的应用，支架治疗颅内动脉狭窄已逐渐成为一种安全有效的方法，血管内支架已成为治疗颅内动脉狭窄相对安全有效的新途径。

Intracranial arteriostenosis is more frequently encountered in those with TIA. The distribution of intracranial or extracranial arteriostenosis may be a predictor of recurrence of stroke.

TIA患者以颅内动脉狭窄多见，不同颅内外动脉狭窄的分布可能是TIA患者卒中复发的血管性预测因子。

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。

Observe by animal experiment and clinic study,this method apply to diagnose middle, serious arteriostenosis especially; But, thenumerical value of gains parameter AUC, DPI, TTP there are no obvious differencein light arteriostenosis and regular group, bring certain difficulty to diagnose.

经动物实验及临床研究观察，此方法尤其适用于诊断中、重度动脉狭窄；然而移植肾动脉轻度狭窄时所得参数AUC、DPI、TTP与正常组数值无明显差异，为诊断带来一定困难。

Cases dogs of normal TK is revealedtransplanted kidney arterial, split the tube of silica gel and slip to arterial, ligate withslipknot, to bring about artificial arteriostenosis in varying degrees. Use caliper tomeasure accurate narrow degree.

将8例正常移植肾犬暴露移植肾动脉，取硅胶管纵行剖开，将之套在暴露的移植肾动脉上，并活结结扎，人为造成不同程度的动脉狭窄，用游标卡尺测量其准确狭窄程度。

Various arterious stenosis diagnosed by CTA were 115 segment, DSA 108 segment.

CTA显示不同程度狭窄的血管段共115段； DSA显示不同程度狭窄的血管段共108段。

Methods Compile 27 borderline cases with cerebral and carotid arterious stenosis, which undergoing cerebral and carotid CTA examination and DSA examination in one week. Compared with DSA, appreciate accuracy of 64-slice CTA in diagnosis of cerebral and carotid arterious stenosis.

搜集临床怀疑颅颈部动脉狭窄性病变患者27例，均行头颈血管CTA检查，并在一周内行DSA检查，将CTA与DSA结果对照，评价64层CTA诊断头颈部动脉狭窄的准确性。

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。
