Correlation analysis of serum Nesfatin-1,TNF-αand insulin resistance in patients with newly diagnosed type 2 diabetes / 中国糖尿病杂志

ABSTRACT

Objective To explore the relation between serum nesfatin-1 ,tumor necrosis factor (TNF)-αand insulin resistance. Methods A total of 105 subjects were enrolled in this study and divided into two groupspatients with newly diagnosed type 2 diabetes mellitus (T2DM group,n= 64)and normal controls (NC group,n= 41). The fasting serum nesfatin-1 and TNF-αlevels were measured by enzyme-linked immuno sorbent assay (ELISA). FPG,HbA1 c,TG,TC,and FIns were also tested. BMI, HOMA-IR,HOMA-β,and ISI were calculated. Results Serum nesfatin-1 and TNF-αlevels were significantly higher in T2DM group than in NC group. Multiple linear regression analysis showed that the most significant influencing factors for nesfatin-1 were TNF-αand ISI(β= 0. 005、-6. 847,P<0. 05). The most significant influencing factors for TNF-αwas HbA1 c (β= 26. 652,P<0. 01). Conclusion Serum nesfatin-1 and TNF-αare significantly elevated in patients with newly diagnosed T2DM,which may influence the glucolipid metabolism through the signal pathway of insulin and play a role in the pathogenesis of T2DM and IR.
