The accuracy of color ultrasound for stenosis of carotid bifurcation, subclavicular artery and vertebral artery were 93.0%, 92.8% and 82.1%.conclusion color ultrasound examination are effective for the diagnosis of carotid bifurcation sterosis, and less effective for the diagnosis of the subclavicular and vertebral artery stenosis because of the poor sensitivity.

彩色多普勒超声检查诊断颈动脉分叉部、锁骨下动脉和椎动脉狭窄的准确度为93.0%、92.8%和82.1%。结论彩色多普勒超声检查可作为诊断颈动脉分叉部位血管狭窄的有效方法；而其对锁骨下动脉及椎动脉狭窄的敏感性较低，诊断价值不大。

It is an ideal operation for applying ilium autografting with vertebral canal posterior wall plastic operation combining pedicle screw fixation to treat burst fracture of thoracolumbar vertebra with spinal stenosis, it is a simple and safe operative technique to entirely decompress in duramater and nerve roots and enlarge bore of vertebral canal therefore eliminating secondary spinal stenosis, the reconstructing of posterior column including spinous process and supraspinal ligament also increasing spinal stability.

自体髂骨移植椎管成形加椎弓根螺钉内固定，对严重胸腰椎爆裂性骨折伴椎管狭窄是一种较理想的手术方法。此方法操作简单、安全，解除神经及硬膜囊压迫的同时扩大了椎管，杜绝了继发性椎管狭窄，重建了后柱结构包括棘突及脊上韧带，增加了脊柱稳定性，值得推广。

Coalescing side crpta stenosis and spinal stenosis are relevant factor of affecting curative effect.

合并侧隐窝狭窄症和椎管狭窄症是影响疗效的相关因素。

结果 椎动脉平直，无压迫4例，其中2例血管痉挛变细；椎动脉迂曲改变，无血管受压5例；椎动脉迂曲、狭窄，明显受压10例；畸形1例。

To test the hypothesis that concentration polarization of atherogenic lipids may occur in the arterial system and play an important role in localization of atherosclerosis, we simulated and measured in vitro the luminal surface concentration of low density lipoprotein in local stenosis at the distal end of carotid artery by number simulation and laser scanning confocal microscopy, then we designed carotid stenosis model to test the role of LDL concentration polarization in atherogenesis.

低密度脂蛋白(low density lipoprotein， LDL)浓度极化可能是动脉粥样硬化局灶性的重要原因，本文以狭窄血管远心端为研究对象，探讨LDL浓度极化对动脉粥样硬化发生、发展的影响。

The patients were divided into 2 groups: group A,50 patients whose angiograms showed no significant stenosis of the RCA, and group B,50 showing at least one significant stenosis.

将100例右优势型冠状动脉病例分为2组：A组50例，右冠状动脉无明显狭窄；B组50例，右冠状动脉至少1处明显狭窄。

Results RAS(defined as ≥50% diameter stenosis) was detected in 22 of the 157 patients (14.01%) and 21 of the 81 patients with coronary artery disease(25.93%) who had at least one coronary artery of ≥50% diameter stenosis, while no RAS was found in patients whose coronary angiograms were normal.

结果 157例患者中，肾动脉狭窄发生率为14.0%；经冠状动脉造影证实的81例冠心病患者中，肾动脉狭窄的发生率为25.9%；冠状动脉造影完全正常的62例患者中，无1例有肾动脉狭窄。

Stens were evaluated to be patent, while 1 stent was not patent. Conclusion: Sixteen slice spiral CT scan of the cardiac coronary artery is a noninvasive,simple and good method. Coronary calcium score and coronary artery stenosis can be evaluated within one study. The patency of stents could also be evaluated. But more experience in more cases of comparative study should be obtained to prove the accuracy of the evaluation of stenosis of coronary arteries and patency of stents.

十六层螺旋CT冠状动脉CT动脉造影(CTA，computer tomography angiography)是一种无创、简便、优良的冠状动脉成像方法，可一次检查完成冠状动脉钙化积分和狭窄评价，也可评价支架通畅情况，但其评价狭窄及支架通畅的准确性有待做更多病例的CTA与常规冠状动脉造影的对照研究。

Mastering the pathophysiology, clinical manifestations and diagnosis of rheumatic valvular disease such as mitral stenosis, mitral insufficiency, aortic stenosis and aortic insufficiency ; generally understanding surgical methods.
