RESUMO
Objectives To investigate changes in serum levels of adiponectin,leptin and erythrocyte membrane insulin receptor among patients with gestational diabetes (GDM),and to study their relation to insulin resistance.Methods Fasting plasma glucose (FPG),fasting serum insulin (FINS), serum levels of adiponeetin and leptin,indices of lipid metabolism,2 h plasma glucose during oral glucose tolerance test (2 h PG),2 h serum insulin during oral glucose tolerance test (2 h INS),as well as number of erythrocyte membrane insulin receptors with high and low appetency and its constants,were determined in 40 patients with GDM and 34 controls with normal glucose tolerance.Insulin resistance index (IRI) was calculated.Results ① Serum levels of leptin and adiponectin were (11.7?2.8) ?g/L and (7.8?1.6) ?g/L,respectively,and number of high appeteney erythrocyte membrane insulin receptor (R_1) and low appetency erythrocytemembrane insulin receptor (R_2) was (43?9) / red cell and (2297?525) / red cell,respectively.Serum level of leptin was significantly higher in those with GDM than those of normal controls (P
RESUMO
Objective To investigate the relationship between insulin resistance and erythrocyte in- sulin receptors in patients with gout associated with macroalbruminuria(MAU).Methods FBG,PBG,FINS, P2hINS,CH,TG,HDL,LDL-c,UA and erythrocyte insulin receptors were determined in 44 patients with MAU,62 patients with normal MAU(NMAU).Results In MAU,the levels of FINS,TG,LDL-c and HOMA-IR were(16?4)mU/L,(2.5?0.6)retool/L,(3.2?0.5)mmol/L and 3.6~1.2 respectively.While they were(13?3) mU/L,(2.3?0.8)mmol/L,(3.0?0.5)mmol/L and 3.0~0.4 in NMAU group.The levels of FINS,TG,LDL-c and HOMA-IR were significantly higher in the MAU patients than those in NMAU patients(P
