ABSTRACT
Objective To explore the association between the different forms of in vivo ghrelin—Acyl ghrelin( AG) ,Des-acyl ghrelin( DAG) and AG/DAG with insulin resistance( IR) in patients with type 2 diabetes mellitus. Methods From June 2017 to November 2017,eighty-three patients with type 2 diabetes hospitalized in (group T2DM) and 40 healthy subjects (group NC) were hospitalized in Jinling Clinical Medicine were selected. Height body mass,blood pressure,blood lipid,glycated hemoglobin ( HbA1c) and fasting blood glucose (FPG),fasting insulin (FINS),and fasting C peptide (F-C-p) were measured,and all subjects were left with fasting serum,and the concentration of AG and DAG were measured by enzyme linked immunosorbent assay (ELISA). The body mass index (BMI),total gastric starvation (T-ghrelin) level,AG/DAG,insulin resistance index ( HOMA-IR) , insulin sensitivity index ( HOMA-IS ) and islet beta cell function ( HOMA- beta ) were calculated. The differences of the above indexes between the two groups were compared, and the relationship between AG,DAG,T-ghrelin,AG/DAG and FPG,HOMA-IR,HOMA-IS and HOMA- beta in T2DM patients were analyzed. Results ( 1) There were no significant difference in SBP、DBP、TC、LDL-C、AG between group NC and group T2DM(P>0. 05). Compared with NC group,the age、TG、BMI、HbA1c、FPG、FINS、HOMA-IR、HOMA-β、AG/DAG were significantly higher in T2DM group ( t=2. 690,-1. 990, 0. 873, 14. 257, 10. 528, Z=2. 885,-3. 483,-2. 284;P<0. 01,P<0. 05) . The HDL-C,F-C-p,HOMA-IS,HOMA-beta,DAG and T-ghrelin in group T2DM were lower than those of NC group( t or Z=0. 477,-3. 812,-3. 395,-4. 4,-2. 916,-2. 834;P<0. 05 or P<0. 01) . ( 2) The correlation analysis showed that there was a positive correlation between AG and FPG in T2DM group (r=0. 252,P<0. 05),DAG and T-ghrelin were negatively correlated with HOMA-IR (r=-0. 394,-0. 384,P<0. 05),and AG/DAG was positively correlated with HOMA-IR (r=0. 394,0. 384,P<0. 05),but is negatively correlated with HOMA-IS (r=-0. 292,P<0. 05). (3) multivariate linear regression analysis showed that FPG in T2DM patients were the influencing factors of AG ( t=2. 865,P<0. 05) ,while FINS and BMI were the influencing factors of DAG( t=-2. 808、-0. 330,P<0. 05) andT-ghrelin( t=-2. 725、-0. 330, P<0. 05) . HOMA-IR and BMI are the influencing factors of AG/DAG ( t=3. 718,3. 069,P<0. 05) . Conclusion The levels of DAG and T-ghrelin in group T2DM were significantly lower than those in the normal population, and was negatively correlated with the insulin resistance index,and the ratio of AG/DAG was closely related to insulin resistance,and the level of AG was mainly affected by fasting blood glucose.
