【摘要】 目的观察肥胖、2型糖尿病患者的血清抵抗素及超敏C反应蛋白(hs-CRP)水平及其与胰岛素抵抗的关系。方法对照组(NC)28例、糖尿病非肥胖组(DM1)30例、糖尿病肥胖组(DM2)30例。酶联免疫测定法检测空腹血清抵抗素,免疫比浊法测定血清hs-CRP。计算胰岛素分泌功能指数(HOMA2-%B)、胰岛素敏感性指数(HOMA2-%S)以及胰岛素抵抗指数(HOMA2-IR)。结果DM1组和DM2组的hs-CRP、抵抗素均高于NC组(P<0.05),且DM2组高于DM1组(P<0.01)。抵抗素与体质量指数(BMI)、hs-CRP、HOMA2-%B、HOMA2-IR存在相关性(r分别为-0.252,0.563,0.225,0.667,P值均<0.05)。hs-CRP与腰围、BMI、HOMA2-IR存在相关性(r分别为0.773,0.594,0.662,P值均<0.05),与抵抗素存在相关性(r为0.563,P<0.05)。校正年龄、血糖之后,hs-CRP仍与腰围、BMI、HOMA2-IR、抵抗素独立相关。结论抵抗素水平在肥胖、2型糖尿病中升高,并与BMI、HOMA2-%B、HOMA2-%IR、hs-CRP均呈显著相关,可能为联系肥胖与胰岛素抵抗的重要因素。抵抗素、炎性因子可能在肥胖、2型糖尿病的发病中起重要作用。更多还原

【Abstract】 Objective To study serum resistin and high-sensitivity C-reactive protein(hs-CRP) level,and their relationship with insulin resistance in patients with obesity and type 2 diabetes mellitus.Methods The subjects were divided into 3 groups: the normal group(NC),28 cases;the type 2 diabetes group with normal weight(DM1),30 cases;and the obese group with diabetes(DM2),30 cases.The serum resistin was measured by enzyme immunoassay and hs-CRP was detected by unoturbidimetry.Homeostasis model assessment β-cell index(HOMA2-%B),insulin resistance index(HOMA2-IR),and insulin sensitivity index(HOMA2-%S) were calculated.Results The serum resistin and hs-CRP levels in the DM1 group were higher than those in the NC group(P<0.05);the levels in the DM2 were higher than those in either the NC group or the DM1 group(P<0.01).Pearson analysis showed that the serum resistin was correlated with BMI,hs-CRP,HOMA2-%B,and HOMA2-IR(r=-0.252,0.563,0.225,0.667,respectively,P<0.05 for all),and that hs-CRP was correlated with WC,BMI,HOMA2-IR(r=0.773,0.594,0.662,respectively,P<0.01 for all),and resistin(r=0.563,P<0.05).After adjusting age and plasma glucose,hs-CRP was still associated with WC,BMI,HOMA2-IR,and resistin.Conclusion The increase of serum resistin level in patients with obesity and type 2 diabetes and its correlation with BMI,HOMA2-%B,HOMA2-%IR,and hs-CRP suggest that resistin may serve as an important link between obesity and insulin resistance.Resistin and hs-CRP play an important role in patients with obesity and diabetes更多还原
