Objective To investigate the relation between different glucose metabolism status and the IL‐6 and IL‐18 levels . Methods The pre‐diabetes group ,type 2 diabetes mellitus(T2DM) group and healthy control group(NC) were selected with 30 ca‐ses in each group .Fasting venous blood was collected for detecting fasting plasma glucose (FPG) ,triglyceride(TG) ,total cholester‐ol (TC) ,low‐density lipoprotein‐cholesterol (LDL‐C) and high‐density lipoprotein‐cholesterol (HDL‐C) levels .Serum IL‐6 and IL‐18 levels were measured by adopting the enzyme‐linked immunosorbent assay(ELISA) .Results The IL‐6 and IL‐18 levels in pre‐diabetes and T2DM groups were significant increased compared with those in the NC group ,the difference was statistically signifi‐cant (P<0 .01) .The IL‐6 level was positively correlated with FPG ,TG and IL‐18(P<0 .05) ,the IL‐18 level was positively correla‐ted with FPG ,TG and IL‐6(P<0 .05) .But IL‐6 and IL‐18 were negatively correlated with HDL‐C(P<0 .05) ,however ,had no cor‐relation with TC and LDL‐C (P>0 .05) .Conclusion IL‐6 and IL‐8 participated in the pathogenesis of T2DM ,their serum concen‐trations can be used as the evaluation indexes of pre‐diabetes screening and reverse intervention effect .

Objective:To explore the vailation of serum sP-selectin,sE-selectin,levels in the patients of pre-diabetic,simple type 2 diabetes mellitus (T2DM) and T2DM with coronary heartdisease(CAD).To investigate the possible mechanism that sP-selectin, sE-selectin accelerate type 2 diabetes mellitus.Methods: Level of serum sP-selectin, sE-selectin was assayed by ELISA in type 2 diabetes with or without coronary heart disease (32 and 34 cases respectively),pre-diabetic (32 cases) and control group(32 cases). Meanwhile BMI,BP,FBS,FINS,TG,CHO,HDL-C,LDL-C,HbA1C were determined in all cases as well as in control group.Results:The serum levels of sP-selectin and sE-selectin in pre-diabetic,type 2 diabetes mellitus with or without coronary heart disease groups were significantly higher than the control group ( P<0.01 ).There was significant positive correlation between serum levels of sP-selectin,sE-selectin and these items including FBG ,FINS,TG,HbA1C,HOMA-IR(P<0.01);but sE-selectin was negatively correlated with HDL-C (P<0.05).Conclusion:sP-selectin,sE-selectin,are risk factors in the initiation and progression of pre-diabetic,type 2 diabetes with or without coronary heart disease;sP-selectin and sE-selectin possibly accelerate type 2 diabetes by inducing insulin resist-ance.
