RESUMEN
Objective To investigate the clinical significance of serum chemokine and hs-CRP levels in patients with type 2 diabetes mellitus with asymptomatic subclinical atherosclerosis.Methods The clinicpathological and follow-up data of 55 patients with Type 2 diabetic from 2012.1 to 2015.12 were collected and reviewed.At the same time,55 patients with non type 2 diabetes were taken as control.Determination of FPG,HbA1c,HDL-C,TC,TG,LDL-C,INS and other indicators by automatic biochemical analyzer,the application of color Doppler ultrasound equipment measurement C-IMT.Correlation using Pearson correlation analysis,risk factor analysis using multiple linear stepwise regression analysis.Results Compared with the control group,the two groups in BMI,WHR,systolic blood pressure,ankle brachial index,FPG,HbA1c,HDL-C,hsCRP,C-IMT,HOMA2-IR and serum chemokines were significantly different,with statistical significance (t =-6.31 ～5.79,P≤0.01 ～ 0.03).In 110 cases of experimental group and control group,the levels of serum chemokines were positively correlated with WHR,HOMA2-IR,C-IMT and hs-CRP (r=0.24～0.29,P=0.01～0.04).C-IMT and age,WHR,systolic blood pressure,diastolic blood pressure,FPG,HbA1c,diabetes duration,hs-CRP was positively correlated (r=0.15 ～0.68,P≤0.01～0.0.04),and the ankle brachial index was negatively correlated (r=-0.32～0.29,P≤0.01).Hs-CRP was positively correlated with HbA1c,HOMA2 IR,serum chemokine,C-IMT (r=0.25～0.32,P≤0.01～0.04),and was negatively correlated with TC and HDL-C (r=-0.27～-0.25,P all 0.02).Cox proportional hazard regression model for multivariate analysis showed that high serum chemokines,hs-CRP and HbA1c were the risk factors of C-IMT (β=0.026～0.658,SE=0.015～0.033,t=2.532～3.421,P≤0.01～0.04).Conclusion High serum levels of chemokines and hs-CRP are the risk factors of C-IMT,and it has important clinical significance for the diagnosis of asymptomatic subclinical atherosclerosis in patients with type 2 diabetes mellitus.
