血管狭窄

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 oral administration of the Cu2+ chelator TM could reduce neointimal thickening after balloon injury in the rat. And the expression and activity of MMP9 were significantly suppressed by moderate copper deficiency induced by TM.

TM诱导的适度铜缺乏能够显著抑制MMP9的表达和活性，这可能是起抑制血管球囊损伤术后再狭窄的机制之一。

Drug eluting stents exhibit efficiency and safety in preventing restenosis, but there still existed problems need to further explore.

OBJECTIVE: To discuss the research and clinical application of drug eluting stents, in addition, to explore the effects of drug eluting stents on preventing and curing coronary restenosis.

目的：通过对目前研究和应用较为广泛的药物涂层支架进行讨论，进而探讨药物涂层支架对防治冠脉血管内再狭窄的作用。

Results There are 17 cases whose CTA display rate is 100% of common carotid artery, external carotid artery and internal carotid artery. 18 branches internal carotid artery stenosis, in them 10 branches light stenosis, 4 branches midrange stenosis, 3 branches heavy stenosis, 1 branches obstruction.

回顾性分析17例经临床或DSA检查证实的颈动脉狭窄的CTA检查结果，对血管显示情况进行评价，其中7例进行了DSA检查并与CTA结果比较。

Gelatin-coated nitinol stent can deliver 〓 to stenting site of local artery directly and efficiently prevent in-stent restenosis through inhibiting VSMC proliferation and neointima formation significantly.

腺病毒介导的〓基因通过蛋白涂层镍钛合金支架可以直接导入靶血管部位，有效地抑制VSMC增生和新生内膜形成，预防支架内再狭窄的发生。

The tracheas were pressed by nodular goitres in 25 patients, and the blood vessels and esophagus were pressed in 29 and 5 patients, respectively. Surrounding organs invaded were not detected in any patients.

Morphological change of injured intimae was examined by light microscope and analyzed using a computerized imaging analysis system.

Dau对损伤内皮所致平滑肌的增殖具有抑制作用，可防止血管再狭窄，其机理可能是通过调节p27的表达实现的。

The proximal stenosis of target coronary artery has significant influence on the TTFM parameters. It has significant influence on the patency of the LIMAs postoperatively in MSCT, but there is no significant influence from the competitive flow on the SVGs.

2靶血管近端狭窄程度对TTFM有显著影响，MSCT方面仅对LIMA桥通畅率影响较大，对SV桥则影响较小。
