Abstract:
Objective To investigate the effects on the improvement of the function of islet β cell by three intensive insulin treatments on newly diagnosed type 2 diabetes(T2D) in different insulin resistant status.Methods Ninety-eight patients of newly diagnosed T2D were divided into two groups:group with overt insulin resistant status ( IR group) ( HOMA-IR ≥ 5 ); group without overt insulin resistant status ( Non-IR group) ( HOMA-IR ＜ 5).According to the condition of patient,there were six subgroups:IR-CSⅡ group ( n = 20 ); IR-glar group ( n = 22 );IR-aspart 30 group (n=23); Non-IR-CSⅡ group (n= 10); Non-IR-glar group (n=12); Non-IR-aspart 30 group (n = 11 ).Subgroups were treated with continuous subcutaneous insulin injection (CSⅡ group),insulin aspart plus insulin glargine ( glar group),and insulin aspart 30 injection ( aspart 30 group) for two weeks,respectively.The levels of fasting plasma glucose (FPG) ,fasting C-peptide(C-P) ,2 h plasma glucose (2 hPG) were measured and homeostasis model assessments of beta cell (HOMA-β) and homeostasis model assessments of insulin resistance ( HOMA-IR) were calculated using fasting C-P.Results The time of blood glucose recover,insulin dosage and the incidence of hypoglycemia of CSⅡ group were lower than those of the glar group and aspart 30 group( P ＜ 0.05 and P ＜0.01 ,respectively).However,there were no significant difference between the glar-group and aspart 30 group ( P ＞ 0.05 ).The insulin dosage of Non-IR-subgroups was significantly lower than the IR-subgroups ( P ＜ 0.01 ).The △HOMA-IR(C-P) of Non-IR-subgroups was lower than the IR-subgroups ( P ＜ 0.05 ).The △HOMA-islet(C-P) of the Non-IR-subgroups was higher than the IR-subgroups ( P ＜ 0.05 ).The △HOMA-IR(C-P) ( 1.79 ± 0.15 and 1.51 ±0.09 in IR and non-IR group,respectively) and △HOMA-islet(C-P) (4.01 ±0.21 and 4.35 ±0.23 in IR and Non-IR group,respectively) of the CSⅡ group were higher than those of the glar group (1.63 ± 0.21 and 1.40 ±0.19 of △HOMA-IR (C-P) and 3.86 ± 0.12 and 4.03 ± 0.18 of △HOMA-islet(C-P) in IR and Non-IR group,respectively) and aspart 30 group ( 1.61 ± 0.13 and 1.42 ± 0.1 1 ) △HOMA-islet (C-P) and 3.88 ± 0.32 and 4.01 ±0.14of△HOMA-islet(C-P)inIRandNon-IRgroup,respeetively)(P＜0.05).Conclusions Thethree intensive insulin treatments for newly diagnosed T2D accompanied with high blood glucose may improve the function of β cell and alleviate insulin resistance,especially the CSⅡ.However,the efficacy on T2D with overt insulin resistant status is limited.
