| 摘要 目的：探讨老年代谢综合征(MS)患者颈动脉内膜中层厚度（IMT）与血管内皮功能及血管粘附因子-1（VCAM-1）的相关性。方法：选取2013年1月～2014年10月我院收治的50例MS患者分为老年组（n=25）和中青年组（n=25），又根据IMT分为正常组和增厚组两个亚组。比较老年组和中青年组患者的临床资料，采用放射免疫分析法检测所有患者内皮素-1（ET-1）水平，采用分光光度计间接比色法检测一氧化氮(NO)水平,采用ELISA法检测VCAM-1水平，采用超声诊断仪检测IMT。结果：老年MS组和中青年MS组临床资料比较，差异均无统计学意义（均P>0.05）；MS患者IMT增厚组的NO水平均低于IMT正常组，而ET-1和VCAM-1水平均高于IMT正常组，比较差异有统计学意义（均P＜0.05）。IMT增厚组间比较，老年MS组的NO水平低于中青年MS组，VCAM-1水平高于中青年MS组，比较差异均有统计学意义（P＜0.05）；老年MS组和中青年MS组的IMT与NO水平呈负相关（r=-0.415，-0.411；P=0.043，0.049），与ET-1和VCAM-1水平呈正相关（r=0.585，0.576；P=0.030，0.036；r=0.547，0.552；P=0.033，0.031）。结论：血管内皮功能障碍和动脉粥样硬化等多重因素促进了MS患者IMT增厚中病理过程的发生和发展。 |

| ABSTRACT Objective: To investigate the correlation between carotid artery intima media thickness(IMT)and vascular endothelial function and vascular adhesion factor-1(VCAM-1)in elderly patients with metabolic syndrome(MS). Methods: Selected 50 cases of patients with MS in our hospital from October 2014 to January 2013 were divided into the elderly group(n=25)and young and middle-aged group(n=25), and were divided into normal group and the thickening group according to the IMT. Compare the clinical data of the elderly group and the young and middle-aged group, detected the level of endothelin-1(ET-1)in all patients by the radioimmunoassay, detected the level of nitric oxide(NO)by spectrophotometer with indirect colorimetric method, detected the level of VCAM-1 by ELISA method, Detected the IMT by ultrasonic diagnostic apparatus. Comparison and correlation analysis between groups on the above indicators. Results: There was no significant difference in the clinical data between elderly MS group and young and middle aged MS group(P>0.05); The levels of NO in the MS patients with IMT thickening group were lower than those in the IMT normal group, while the levels of ET-1 and VCAM-1 were higher than those in the IMT normal group,the differences were statistically significant(P<0.05); Comparison of IMT thickening group, the level of NO in the elderly MS group was lower than that in young and middle aged MS group, the level of VCAM-1 was higher than that in the young and middle aged MS group, and the differences were statistically significant(P<0.05); IMT was negatively correlated with the level of NO in the elderly MS group and young and middle aged MS group(r=-0.415, -0.411; P=0.043, 0.049), and were positively correlated with the levels of ET-1 and VCAM-1(r=0.585, 0.576; P=0.030, 0.036; r=0.547, 0.552; P=0.033, 0.031). Conclusion: Multiple factors, such as vascular endothelial dysfunction and atherosclerosis,promote the occurrence and development of IMT thickening in MS patients. |
