ABSTRACT
Objective To study the effects of the serum Nesfatin-1 level change by type 2 diabetes in patients with Non-alcoholic fatty liver,and provides a reliable basis for its prysiological effects.Methods Selected 300 cases with type 2 diabetes mellitus in deoartment of endocrinology from January 2014 to January 2016 in Affiliated Hospital of Yan'an University as the object of this study.According to whether the patients were combined with non-alcoholic fatty liver,the patients were divided into T2DM with NAFLD group (150 cases) and T2DM without NAFLD group (150 cases).In addition,150 volunteers for healthy check-up in the hospital were selected as control group.Compared the serum Nesfatin-1 levels of three group patients,and monitored the insulin resistance index of two groups patients with type 2 diabetes.Results BMI,TG,ALT and INS of NGT(23.1±1.9,1.7±0.5,26.9±12.7 and 9.7±2.4,respectively) group and T2DM (22.1±2.5,2.0± 0.9,22.1 ± 10.5 and 11.2± 4.5,respectively) group were significantly lower than those of T2DM-NAFLD group (26.5 ± 3.8,3.0± 2.5,31.9 ± 11.5 and 14.2 ± 6.5;all P value were 0.00).FBG,HbAlc,LDL-C,HOMA-IR and Nesfatin-1 of T2DM group (8.4±3.1,8.8±2.7,3.4±1.0,4.5±2.9 and 6.9±3.0) and T2DM-NAFLD group (8.2±2.7,8.5± 1.9,3.7 ± 2.1,5.2 ± 2.7 and 5.2 ± 2.7) were significantly higher than those in serum NGT group (5.1 ± 0.5,5.4 ± 0.4,2.7 ±0.8,2.7±0.8 and 2.3± 0.7,all P value were 0.00).The serum Nesfatin-1 levels of T2DM patients and patients with T2DM-NAFLD had moderate correlation (r=-0.421,P＜0.05) by Pearson correlation analysis.BMI,TG and serum Nesfatin-1 levels were closely associated with the occurrence of fatty liver (r=-0.402 ～ 0.273;P=0.00 ～ 0.01).Conclusion Nesfatin-1 may be involved in type 2 diabetes mellitus and the occurrence of non-alcoholic fatty liver.
