代谢综合征患者大动脉顺应性与颈动脉内-中膜厚度变化的研究

目的 探讨代谢综合征（MS）患者大动脉顺应性及颈动脉内-中膜厚度（IMT）的变化。方法 64例MS患者和56例年龄相匹配的正常对照者，测定所有人选者颈动脉-股动脉的脉搏波速度（PWV）、颈动脉IMT，同时检测其身高、体重、腰围、臀围、血压、血糖、血脂水平，并计算体重指数（BMI）、腰臀比（WHR）。结果 MS组PWV和颈动脉IMT与对照组比较，差异有统计学意义（P〈0．05）。MS组颈动脉IMT与年龄、腰围、收缩压、脉压、总胆固醇、甘油三酯、PWV呈显著正相关（P〈0．01），与高密度脂蛋白-胆固醇呈显著负相关（P〈0．01）；PWV与年龄、收缩压、脉压、体重指数、总胆固醇、甘油三酯、颈动脉IMT、体重呈显著正相关（P〈0．05），与高密度脂蛋白-胆固醇呈显著负相关（P〈0．01）。结论 MS患者PWV及颈动脉IMT均明显升高，已经存在大动脉顺应性的减退；MS患者大动脉顺应性的变化与年龄、血压、肥胖及血脂紊乱有关，且PWV与颈动脉IMT有明显的相关性。

Study of the change of large arterial compliance and carotid artery intima-media thickness in patients with metabolic syndrome

Objective To explore the roles of IL-8, sICAM-1 and sE- selectin in the airway inflammation of chronic obstructive pulmonary disease (COPD). Methods The levels of IL - 8, sICAM -1 and sE-selectin in the serum were measured by double-sandwich ELISA in 40 COPD patients and 20 healthy persons. The COPD patients were divided into two groups: 20 cases in COPD a-cute exacerbation group and 20 cases in stable period group. Results The IL- 8, sICAM- 1 and sE - selectin level of serum in patients with COPD acute exacerbation group and stable period group were obviously higher than those in healthy group, and patients with COPD acute exacerbation group was obviously higher than those in stable period group (P<0.05 or P < 0.01). The IL - 8 and sICAM - 1 level of serum in healthy group in smokers were significantly higher than those in nonsmokers (P< 0.05). Conclusion IL - 8, sICAM - 1 and sE - selectin play important roles in the airway inflammation of COPD.
