ABSTRACT
Objective To investigate the influence factors of serum Angptl 2 levels is to explore the relationship between serum Angptl 2 and carotid atherosclerosis (CAS) in patients with type 2 diabetes mellitus (T2DM). Methods 114 cases of T2DM in clinic were selected.According to the results of color doppler ultrasonography,the patients were divided into T2DM with CAS group(T2DM + CAS,n=58)and simple T2DM group(n= 56).56 healthy subjects were selected as normal control (NC)group during the same period.ELISA method was used to detect the level of serum Angptl 2. Results Serum Angptl 2 levels were significantly higher in T2DM + CAS group and T2DM group than in NC group [(69.83 ± 12.07) vs (42.93 ± 10.44)vs (24.26 ± 8.78)ng/ml,P< 0.01].Correlation analysis showed that serum Angptl 2 was positively correlated with age,BMI,SBP,DBP,TC,TG,LDL-C,FPG and HbA1c in T2DM patients (r=0.574,0.325,0.528,0.308,0.396,0.387,0.295,0.536 and 0.601,respectively,P<0.01),and negatively correlated with HDL-C and FIns in T2DM patients (r= -0.248,-0.352,P<0.01).Similarly,multiple regression analysis showed that FIns,and HbA1c were the independent factors of serum Angptl 2 (β= -2.186,2.680,P<0.01). Conclusion Serum Angptl 2 level is closely related to obesity,blood pressure,blood glucose,blood lipid and insulin.Serum Angptl 2 may play an important role in the development of T2DM and carotid atherosclerosis.
