摘要
目的 探讨血清胱抑素C(Cys C)及趋化素水平与2型糖尿病(T2DM)亚临床动脉粥样硬化的关系.方法 横断面研究.选择2016年1月至2018年1月武汉市第四医院收治的颈动脉内膜中层厚度(IMT)<1.1 mm的T2DM患者,男100例,女80例,年龄40~60岁.臂踝脉搏波传导速度(baPWV)≥1 700 cm/s者为观察组(亚临床动脉粥样硬化,85例),baPWV<1 700 cm/s者为对照组(非亚临床动脉粥样硬化,95例).对两组患者行体格检查、血生化检查,测定血清Cys C和趋化素水平,分析其与亚临床动脉粥样硬化的关系.结果 观察组血清肌酐与baPWV有相关性(r=0.167,P=0.011),而对照组二者无明显相关性(r=0.105,P=0.070).多重线性回归分析显示,年龄、糖尿病病程、血清肌酐、估算肾小球滤过率(eGFR)、Cys C和趋化素均与baPWV独立相关(均P<0.05),而超敏C反应蛋白(hsCRP)、糖化血红蛋白(HbAlc)与baPWV无明显相关性(均P>0.05).血清Cys C(标准化β=0.393,P=0.003)和趋化素(标准化β=0.340,P=0.007)升高是动脉粥样硬化的相关因素.结论 血清Cys C及趋化素水平可能与T2DM亚临床动脉粥样硬化的发生发展相关.
Objective To investigate the relationships between serum cystatin C (Cys C), chemerin levels and subclinical atherosclerosis in type 2 diabetes mellitus (T2DM) patients. Methods A cross-sectional study was carried out between January 2016 and January 2018, and T2DM patients with carotid intima-media thickness (IMT) less than 1.1 mm were selected as subjects (100 males and 80 females, aged 40-60 years). The brachial-ankle pulse wave velocity (baPWV) ≥ 1 700 cm/s was set as the observation group (subclinical atherosclerosis) and baPWV<1 700 cm/s as the control group (non-subclinical atherosclerosis). Physical and blood examination were performed in both groups. Serum Cys C and chemerin levels were measured and their relationship with subclinical atherosclerosis was analyzed. Results There was a statistically significant correlation between serum creatinine (r=0.167, P=0.011) and baPWV in the observation group, but not in the control group (r=0.105, P=0.070). Multiple linear regression analysis showed that age, duration of diabetes, serum creatinine, estimated glomerular filtration rate (eGFR), Cys C and chemerin were independently associated with baPWV, while high sensitive C reactive protein (hsCRP) and glycosylated hemoglobin (HbA1c) were not associated with baPWV. The elevation of serum Cys C (β′=0.393, P=0.003) and chemokine (β′=0.340, P=0.007) were correlative factors for atherosclerosis. Conclusion The level of serum Cys C and chemerin is possibly related to the occurrence and development of subclinical atherosclerosis in T2DM patients.
