老年颈动脉硬化患者血清炎症因子与中医证型的关系

目的研究老年颈动脉硬化患者不同中医证型血清内皮细胞粘附分子-1（ICAM-1）、血管细胞粘附分子-1（VCAM-1）、E选择素（E-selectin）、P选择素（p-selectin）、白细胞介素-6（IL-6）和C反应蛋白（CRP）等炎症因子水平。方法收集176例颈动脉硬化患者，采用酶联免疫吸附法测定血清ICAM-1、VCAM-1、E-selectin、p-selectin、IL-6和CRP等水平，比较痰证、血瘀证和精髓亏虚证型颈动脉硬化患者血清粘附分子水平变化。结果发现各型颈动脉硬化患者血清炎症因子水平均较对照组显著上升；颈动脉硬化痰证组患者血清ICAM-1和VCAM-1均较血瘀证和精髓亏虚证患者显著上升（P〈0．05）。结论老年患者外周血中炎症因子水平可以在一定程度上反映患者的颈动脉硬化程度，老年颈动脉硬化痰证患者外周血中粘附分子水平的变化具有一定特异性，痰的微观实质可能与粘附分子之间存在某种内在联系。

Research of Serum Inflammatory Factors in Aged Carotid Artery Atherosclerosis Patients with Different Chinese Medicine Syndromes

Objective To study the level of serum ICAM-1, VCAM-1, E-selectin, P-selectin, IL-6 and CRP in different Chinese medicine syndrome patients with carotid artery atherosclerosis. Methods Blood sample were collected from 176 patients with carotid artery atherosclerosis. The concentration of ICAM-1, VCAM-1,E-selectin, P-selectin, IL-6 and CRP were tested by means of ELISA. The subjects were divided into 3 groups according to the Chinese medicine syndrome, and the concentrations of inflammatory factors were compared among the 3 groups. Results Compared with control group, the level of inflammatory factors in the patients with carotid atherosclerosis was higher, and the levels of ICAM-1 and VCAM-I in phlegm group were higher than blood stasis group and marrow deficiency group （P 〈0.05）. Conclusions The level of serum inflammatory factors of aged carotid artery atherosclerosis patients can reflect the degree of carotid artery atherosclerosis. The level of serum celluar adhersion molecules of patients with carotid atherosclerosis is connected with phlegm syndrome.
