摘要

目的:研究导痰汤是否能通过对内皮细胞黏附分子-1（intercellular adhesion molecular-1

ICAM-1）和p21通路的调节而干预颈动脉粥样硬化。方法:将25只雄性新西兰白兔随机分为正常对照组、模型组、导痰汤治疗组（分为高、中、低剂量组）。对照组给予基础饲料喂饲

模型组和导痰汤治疗组予以高脂饲料喂饲

并在喂饲1周后实施颈动脉内膜空气干燥术

术后导痰汤治疗组分别按照10

6 g.kg-1

ig每日给药1次。4周后处死家兔

取每只家兔右侧颈动脉远端1 cm

固定后行HE染色

观察病理改变。应用免疫组化SABC法检测ICAM-1和p21表达情况。结果:模型组血管内皮细胞、平滑肌细胞的胞浆中有ICAM-1（0.200±0.035）和p21（0.297±0.097）强阳性表达

显著高于对照组ICAM-1（0.037±0.005）

p21（0.078±0.016）

（P<0.01）。导痰汤低、中、高剂量治疗组细胞内ICAM-1（0.166±0.043

0.104±0.011

0.098±0.010）和p21（中剂量:0.173±0.021

高剂量:0.128±0.026）阳性表达显著低于模型组（P<0.05）

且随剂量的增加

导痰汤对ICAM-1和p21的抑制逐渐增强;而p21与ICAM-1水平呈显著正相关（r=0.772

P<0.01）。结论:导痰汤可以有效抑制颈动脉硬化家兔血管内皮细胞中ICAM-1和p21的表达。

Abstract

Objective:To study the influence of Daotan decoction on the expression of intercellular adhesion molecular-1（ICAM-1） and p21 in carotid atherosclerosis rabbits.Method: Twenty-five male rabbits were divided into control group

model group and Daotan decoction group.Control group was treated with basic diet;model group and Daotan decoction group were treated with both high-fat diet and carotid artery intima air drying operation.Daotan decoction group was treated with Daotan decoction

at dose of 10

6 mg · kg-1

for 4 weeks.Then the right carotid was cut and fixed.The expression of ICAM-1 and p21 was assayed by immunohistochemistry and pathological staining.Result: Compared with control group（ICAM-1:0.037±0.005

p21:0.078±0.016）

the expression of ICAM-1（0.200±0.035） and p21（0.297±0.097） in model group was significantly increased（P<0.01）.And compared with model group

Daotan decoction could significantly restrain ICAM-1（low dose group: 0.166±0.043

medium dose group: 0.104±0.011

high dose group: 0.098±0.010） and p21（medium dose group: 0.173±0.021

high dose group: 0.128±0.026） expression（P<0.05）.Also

there was significant positive relationship between the expression of ICAM-1 and p21（r=0.772

P<0.01）.Conclusion: Daotan decoction could restrain ICAM-1 and p21 expression in carotid atherosclerosis rabbits.
