Abstract: Objective:To detect the serum levels of CTRP3 and 25(OH) D in the individuals with different glucose metablism states,and to discuss the influence factors and analyze their relationships with insulin resistance(IR). Methods:Forty-four patients newly diagnosed T2DM(T2DM group),42 patients with impaired glucose regulation(IGT group),and 54 cases of normal controls(normal control group) were selected.The serum CTRP3, FPG,HbA1c,FIns,TG,TC,HDL-C, LDL-C,FIns of the subjects in various groups were determined, respectively;the BMI,HOMA-IR,HOMA-β were calculated.Pearson correlation analysis was used to analyze the correlation between two factors and multivariate stepwise regression analysis was used to analyze the influencing factors of HOMA-IR and HOMA-β. Results:Compared with normal control group, the serum levels of HDL-C, 25(OH)D and HOMA-β of the patients in IGT group were significantly decreased (P<0.05); the levels of serum FPG, HbA1c, TG, TC, FIns and BMI, HOMA-IR of the patients in T2DM group were significantly increased (P<0.05), while the levels of serum CTRP3, HDL-C, 25(OH)D and HOMA-β were significantly decreased(P<0.05). Compared with IGT group, the levels of serum FPG, HbA1c, TG, FIns, and HOMA-IR of the patients in T2DM group were significantly increased (P<0.05), and the level of serum HDL-C and HOMA-β were significantly decreased (P<0.05).The serum CTRP3 level was negatively correlated with the levels of HbA1c, FIns and HOMA-IR (r=-0.391, P<0.05; r=-0.198, P<0.05; r=-0.481, P<0.05); the 25(OH)D level was negatively correlated with the TG, FPG levels and HOMA-IR (r=-0.209, P<0.05; r=-0.406, P<0.05; r=-0.306, P<0.05), and positively correlated with HOMA-β (r=0.329, P<0.05) in the different glucose tolerance individuals. HbA1c and CTRP3 were the independent influencing factors of HOMA-IR, and 25(OH)D, FPG and HbA1c were the independent influencing factors of HOMA-β. Conclusion:The serum CTRP3 and 25(OH)D levels are negatively correlated with IR,and they have the inhibitory effects in the occurrence and development of diabetes mellitns.
