颈动脉的

After two experienced doctors of Traditional Chinese Medicine who knew nothing affirmed the pulse is wiry pulse, we used sphygmograph to note the sphygmogram of carotid. Then after the rabbits breathed calmly, two experienced doctors of Traditional Chinese Medicine who knew nothing affirmed the pulse was the normal pulse ,we noted the the sphygmogram of carotid under the same pulse-taking pressure. After classifying the parameters in the sphygmogram of carotid, we analyzed them by time domain.

2.2 给予家兔疼痛性刺激建立弦脉模型在非麻醉状态下将家兔行颈部手术，暴露颈动脉，经两名有经验的中医师双盲取脉，使用脉图仪记录颈动脉脉图，待家兔呼吸平稳后再由两名有经验的中医师双盲取脉，确认为平脉后在同样的取脉压力下记录颈动脉脉图，对脉图参数进行分类后做时域分析。

Methods Rabbits were randomized to three groups. Complex model group were fed with feed containing 0.5% cholesterol for 3 weeks. At the fourth, eighth and twelfth weeks, rabbits were given injection of lipopolysaccharide (1 μg) at auricular artery, cervical part and fold inguen, respectively. Normal group were fed with normal diet, while High cholesterol group were fed with feed confaining 0.5% cholesterol only. After 16 weeks, vascular tissues were analyzed using morphometric and histological methods, and the sera were checked for cholesterol, LDL-C, C-reaction protein and tumor necrosis factor-α. Results The cholesterol and LDL-C of High cholesterol group were increased, compared to those of normal group.

给含0.5%胆固醇的饲料，3周后，分别在第4、8、12周采用耳动脉内、颈部、腹股沟处肌肉注射大肠埃希菌脂多糖，并设立正常组和单纯高脂组。16周后观察兔的一般状态，取血清检查血脂六项、C-反应蛋白和TNF-α，取耳动脉、颈动脉、主动脉弓、胸主动脉、腹主动脉、髂动脉、肝脏，放置4%多聚甲醛中过夜，常规行HE染色，检查血管病变和相关脏器病变情况。

Observe the rate of the atherosclerosis spot from a.carotis communis\a,profunda femoris and a.renalis.

用多普勒超声检查患者颈动脉、下肢动脉及肾动脉粥样斑块的发生率。

The expression of AT2R gene can be regulated efficiently in vivo by local delivery of MSC with dual-stable expression of AT2R gene, thus reduces the formation of intimal hyperplasia.④AT2R gene can influence the expression of ECM and significantly promote the cellular apoptosis in the injury rat carotid artery.⑤These data demonstrate the clinical potential of AT2R regulatable expression to prevent restenosis after PCI.

研究结论：(1)与VSMC直接接触可以诱导MSC向血管成分细胞分化；(2)构建的Dox-on可调控的MSC细胞株诱导活性可靠，使外源AT2R基因的表达处于有效的主动控制下；(3)局部导入MSC不影响球囊损伤后大鼠颈动脉新生内膜增生；(4)由MSC介导的AT2R可调控表达受到Dox的良好调控，可有效抑制球囊损伤后大鼠颈动脉新生内膜增生；(5)AT2R影响血管损伤后修复时ECM成分的表达，并促进细胞凋亡的发生，可能是AT2R介导抑制新生内膜形成的机制。

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。
