Plasma Ang Ⅰ and Ang Ⅱ levels, chymase mRNA levels, arteries' PCNA positive percents and the thickness of carotid artery were measured.

通过测定血浆Ang Ⅰ及AngⅡ住水平、糜酶 mRNA表达水平、颈动脉细胞增殖核杭原阳性率及颈动脉各层厚度观察曲尼司特对犬颈动脉损伤后狭窄的作用。

Results (1)CIMT and FIMT in CHD group were significantly higer than those in non-CHD group(p＜0.05), The detection rate of plaques in CHD group was significantly higer than those in non-CHD group(p＜0.05);(2) The sensitivity of carotid and femoral atherosclerosis plaques in young CHD patients was 62% and 57%. The specificity was 90% and 86%. The positive predictive value of carotid and femoral atherosclerosis plaques in young CHD patients was 92% and 88%. The negative predictive value was 58% and 53%. The predictive value of combinant measurement of carotid and femoral atherosclerosis plaques was not improved.

结果 （1）冠心病组CIMT、FIMT与非冠心病组比较，前者均高于后者（p＜0.05）；冠心病组颈动脉、股动脉粥样硬化斑块检出率均明显高于非冠心病组（p＜0.05）；（2）颈动脉、股动脉粥样硬化斑块预测年轻冠心病的敏感性分别为62%、57%，特异性为90%、86%，阳性预测值分别为92%、88%，阴性预测值为58%、53%；颈动脉、股动脉联合检测未见明显提高预测值。

For those in control group (n=14), the animals did not undergo any surgery of the nerve fibers and ganglia. In Vi group (n=9), the animals underwent bilateral resection of the nasociliary and postganglionic parasympathetic nerve fibbers. In SCG group (n=8), the animals underwent bilateral resection of supper cervical ganglia. In V1+SCG group (n=9), the animals underwent both surgeries as Vi and SCG group did. In sham operation group (n=11), the animals underwent carotid manipulation with blunt-tipped forceps as well as dissection of nasociliary and postganglionic parasympathetic nerve fibers around the ethmoidal foramen, without cutting any nerves. SCS was performed on rats and CBF was monitored by laser Doppler flowmeter recordings.

SD大鼠分5组：对照组（n=14，不对神经纤维和神经节作任何手术处理）、V1组（n=9，切断双侧鼻睫状神经及其副交感节后纤维）、SCG组（n=8，切断双侧颈上神经节）、V1+SCG组（n=9，切断双侧鼻睫状神经及其副交感节后纤维和双侧颈上神经节）、假手术组（n=11，手术暴露双侧鼻睫状神经及其副交感节后纤维和双侧颈上神经节，但不切断神经纤维或神经节）；给予大鼠SCS，并用激光多普勒实时记录脑血流。
