OBJECTIVE:To explore the effects of dual-phase insulin aspart with different dosing regimens on the related indica-tors of type 2 diabetic (T2DM) patients with poor glycemic control. METHODS:70 T2DM patients with poor glycemic control were randomly divided into group A and group B. All patients were given metformin and stopped other antidiabetic drugs;based on it,group A was additionally given Dual-phase insulin aspart injection,0.5 U/(kg·d),in the morning and evening before a meal by subcutaneous injection;group B was given Dual-phase insulin aspart injection,0.5 U/(kg·d),once before lunch time for 6-10 U and other twice in the morning and evening before a meal by subcutaneous injection. Both groups were treated for 12 weeks. Glu-cose control rate,glucose control time,and glucose indicators,daily fluctuations of glucose before and after treatment and incidenc-es of hypoglycemia and adverse reactions in 2 groups were observed. RESULTS:Glucose control rate in group B was significantly higher than group A,glucose control time was significantly shorter than group A,incidence of hypoglycemia was significantly low-er than group A(P<0.05). After treatment,glucose indicators and daily fluctuations of glucose in 2 groups were significantly lower than before,and group B was lower than group A(P<0.05). There were no obvious adverse reactions during treatment. CONCLU-SIONS:Conpared with 2 times a day,Dual-phase insulin aspart with 3 times a day for administration can effectively improve the glucose control rate and glucose levels in the treatment of T2DM patients with poor glycemic control,with good safety.
