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.
ABSTRACT
?-HCH. The average of pp'-DDE in the surface water was the highest, 0.062 ?g/L. In the water in the deep well of 70 meters, organochlorine was still found. Conclusion The residues of organochlorine pesticide in different soil and water of the agricultural products base in Xiaogan have been detected, the contents are under the related national standard limitation, but the potential threat of the accumulation of organic chlorine pesticide should not be underestimated.
ABSTRACT
? in the blood. There were three isomeric compounds of DDT in the fat and two in the blood were detectable. Conclusion There was still accumulation of HCH and DDT in human body fat and blood in Xiaogan population although the accumulative levels were significantly lower than that of the allowable residue standard of China.
