Results The back flow of trouble side vertebral artery caused by the stenosis of innominate artery or subclavian artery were classified into 4 grades.

将锁骨下动脉或无名动脉狭窄引起的患侧椎动脉反流分为四级：0级2例，1级3例，2级9例，3级1例。

Methods DSA was performed in 56 patients with intercranial artery TIA and the clinical and distribution of carotid artery stenosis were analyzed, while TCD was performed in 46 patients and CTA was performed in 54 patients with TIA, then sensitivity, specifity and total consistent rate of TCD and CTA were calculated with Kappa test.

选取56例颈内动脉TIA患者行全脑血管造影检查，结合DSA检查结果分析其临床及颈动脉狭窄特点；同时对46例患者进行了TCD检查，54例患者进行了CTA检查，应用Kappa检验分析TCD和CTA检查的敏感性、特异性和符合率。

Eighteen patients had multilevel anterior cervical discectomies with or without internal fixation, 22 patients had decompressive surgery (12 laminectomies and 10 intersegmental decompressions) for multiseg- ment spinal stenosis, 15 patients had laminectomy with posterior spinal fixation, and remaining 9 patients had laminectomy and excision of spinal tumor.

18例患者行多极前颈椎间盘切除术伴或不伴内固定， 22例患者因多节段椎管狭窄行减压手术（ 12例椎板切除术和10例节间减压）， 15例行椎板切除、后脊柱固定术，其余9例行椎板切除术和脊髓肿瘤切除术。

Likewise, lumbar spinal stenosis is being treated with less invasive procedures such as interspinous process spacers.

同时，也正在使用创伤小的系统例如棘突间装置治疗腰椎管狭窄症。

Patients with symptomatic lumbar spinal stenosis underwent magnetic resonance imaging to study changes in the lumbar spine in arious postures before and after implantation of the X STOP Interspinous Process Distraction Deice St.

研究目的：观察内固定装置在体内的作用。背景资料：以前的研究显示椎管和椎间孔在屈伸过程中减小。

Although there is fair evidence that articial disc replacement is similarly effective compared to fusion for single level degenerative disc disease and that an interspinous spacer device is superior to nonsurgical therapy for 1- or 2-level spinal stenosis with symptoms relieved with forward exion, insufcient evidence exists to judge longterm benets or harms.

尽管已有相当的证据证明人工椎间盘置换治疗单节段脊柱退变疾病具有和融合手术类似的疗效，也有相当的证据证明棘突间支架治疗1～2个节段伴间歇性跛行的椎管狭窄的疗效优于非手术治疗，但以上都缺乏长期随访的证据。

Summary of Background Data. The X Stop Interspinous Process Distraction Deice is a relatiely new interspinous implant designed for patients with symptomatic spinal stenosis particularly neurogenic claudication.

背景资料概述：对于存在腰椎管狭窄症并有神经源性跛行表现的患者而言，X STOP是一种相对较新的棘突间植入装置。

Methods: After transferred pcDNA3.1/hTM plasmid into rabbit artery by high-pressure injection, rabbit common iliac artery were cut and anastomosed again. At the 14 days and 28days after second operation, we checked inside diameter of anastomotic stoma and blood flow velocity by color Doppler. The treated artery were sliced and stained by Verhoeff. Local neointima formation and the ratio stenosis of intervascular were calculated by computer.

用注射式加压转染的方式对兔动脉壁转染pcDNA3.1/hTM质粒，再制造动脉损伤-阻滞模型，于术后14天、28天用彩色多普勒观察活体吻合口内径和血流流速；再做病理切片Verhoeff染色，观察血管内膜增生的程度、部位，计算血管内膜面积、中膜面积和血管狭窄率。

By univariate analysis, deep-seated AVMs, small AVMs, deep venous drainage , a single draining vein and intranidal aneurysm were associated with hemorrhagic presentation. There was no statistically significant relationship between gender, age, type of arterial feeders, type of nidus, stenosis of draining vein and AVM hemorrhage.

单因素分析表明，深部脑AVM、小型脑AVM、深静脉引流、单一静脉引流和畸形血管团内动脉瘤与脑AVM出血相关，性别、年龄、动脉血供类型、畸形血管团类型和引流静脉狭窄与脑AVM出血无相关性。

Results: 68.9%of the lesions located superficially; There were 79.3%intracranial AVMs with volume ranged 0～30mm3; 16.9%intracrnial AVMs had associated with aneurysm including feeding artery aneurysm and intranidal aneurysm; There were 8.2%intracranial AVMs with venous stenosis.

结果：表浅部位者占68.9％；体积为0～30mm3者占79.3％；严重盗血者占19.7％；发现与颅内AVM相关的动脉瘤占16.9％；发现中央静脉引流及混合静脉引流者共53.0％；有引流静脉狭窄者占8.2％。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
