Significance of combined detection of five markers in patients with type 2 diabetes mellitus / 国际检验医学杂志

ABSTRACT

Objective To explore the relationship and clinical significance among glycosylated hemoglobin (HbA1c),fasting blood glucose (FPG),insulin (Ins),C peptide (CP)and urinary mirco-albumin (urine m-Alb)inpatients with type 2 diabetes melli-tus (T2DM).Methods A total of inpatients with type 2 diabetes were choose in this study and divided into mild diabetic group (HbA1c ≤ 9%)with 45 cases,severe diabetic group (HbA1c > 9%)with 44 cases.Twenty healthy persons were selected into control group.The levels of HbA1c,FPG,Ins,CP and m-Alb in urine of each group were detected and compared,the relationships of them were analyzed.Results There were significant differences on the levels of HbA1c,FPG,Ins,CP and m-Alb in urine of each group,and the former three indicators from low to high followed by the control group,the mild diabetic group,the severe diabetic group.There was no significant difference on the level of Ins between the control group and the severe diabetic group(P >0.05), but the level of Ins in the mild diabetic group was significant higher than that of the control group and the severe diabetes group (P <0.05).The CP level in the mild diabetic group was significant higher than that in the control group (P <0.05),and has a posi-tive correlation with the level HbA1c (r=0.427,P <0.05 ).The CP level in the severe diabetic group was significant lower than that in the control group,(P <0.05)and was negatively correlated with the level HbA1c (r=-0.415,P <0.05).Conclusion The joint detection of HbA1c,FPG,Ins,CP and urine m-Alb has positive significance to control type 2 diabetes,protect islet function and prevent diabetic nephropathy,CP is better than Ins on the assessment of the secretory function of islet,and CP might be in-volved in the occurrence and development of diabetic nephropathy.
