目的测定肥胖及新诊断2型糖尿病患者血清apelin水平,探讨apelin与体脂、糖、脂代谢、胰岛素抵抗等的相关性。方法62例2型糖尿病患者和72例正常糖调节(NGR)者按体重指数(BMI)≥25kg/m^2或〈25kg/m^2又各自分为超重/肥胖与正常体重亚组,采用放射免疫分析法检测空腹血清apelin水平,同时检测空腹血糖(FPG)、HbA1C、血脂各项指标及空腹胰岛素(FINS)水平,计算BMI和腰臀比,并以稳态模型计算胰岛素抵抗指数(HOMA-IR)。结果校正年龄及性别后,2型糖尿病组血清apelin水平高于NGR组[(317.9±99.6vs279.0±66.8)ng/L,P〈0.01],2型糖尿病组和NGR组中的超重/肥胖者均高于非肥胖者[(354.0±114.4vs274.1±53.0)ng/L,(299.2±74.5vs252.8±48.9)ng/L,均P〈0.05],且2型糖尿病超重/肥胖组明显高于NGR肥胖组(P〈0.01);偏相关分析显示,空腹血清apelin与BMI、ln(HOMA-IR)、FPG、总胆固醇(TC)呈正相关(r=0.353,r=0.355,r=0.224,r=0.241,均P〈0.01),与腰围、收缩压呈正相关(r=0.263,r=0.183,P〈0.05)。多元逐步回归分析发现,BMI、ln(HOMA—IR)和TC是血清apelin的独立相关因素。结论血清apelin水平在肥胖和初发的2型糖尿病人群中升高,且与BMI、HOMA-IR及脂代谢相关,推测apelin可能参与构成胰岛素抵抗综合征的病理生理基础。 相似文献

肥胖和非肥胖的2型糖尿病患者胰岛素敏感性和β细胞功能研究 总被引:8,自引:0,他引:8
目的 探讨在2型糖尿病患者中肥胖对胰岛素抵抗程度和胰岛β细胞分泌功能的影响。 方法 运用减少样本数的Bergman微小模型技术结合多样本静脉葡萄糖耐量试验检测正常个体(15名)、肥胖和非肥胖2型糖尿病患者(分别为20和14例)的胰岛素敏感指数(S_I)、机体对葡萄糖的急性胰岛素反应(AIRg)和处理指数(DI=S_I×AIRg),同时测定其它临床指标,包括体重指数、腰臀比等。结果 与正常对照组相比,2型糖尿病患者的S_I、AIRg和DI都明显降低(P<0.01)。肥胖组的S_I较非肥胖组低(P<0.05),而其AIRg和DI水平较高(P<0.05),差异显著。结论 肥胖2型糖尿病患者比非肥胖患者存在更为严重的胰岛素抵抗,但机体早期胰岛β细胞胰岛素分泌功能相对能部分代偿。 相似文献

Islet function and insulin sensitivity in the non-diabetic offspring of conjugal type 2 diabetic patients 总被引:3,自引:0,他引:3
To determine whether the genetic predisposition towards Type 2 diabetes was associated with a defect in either islet-cell function or insulin action, 12 non-diabetic offspring each of whose parents both had Type 2 diabetes were studied, together with 12 control subjects matched for age, sex, and weight. Fasting plasma glucose was higher in the offspring (5.5 +/- 0.1 mmol l-1 (mean +/- SE)) than in the matched controls (5.1 +/- 0.1 mmol l-1) (p less than 0.05). Using an IVGTT insulin sensitivity was not significantly lower in the offspring compared with their controls (3.1 +/- 0.5 vs 3.8 +/- 1.0 min-1 mU-1 l 10(-4)). There was no significant difference in any of the measures of insulin secretion (first- and second-phase response to IV glucose, slope of glucose potentiation, and maximal glucose regulated insulin secretory capacity). Glucagon secretion measured before and after a stimulus of IV arginine at varying plasma glucose concentrations was virtually identical in the offspring and their controls. Among a total of 28 non-diabetic subjects of differing body-weights there was a significant inverse relationship between insulin sensitivity and insulin secretion. When adjusted for their generally lower insulin sensitivity, maximal insulin secretory capacity was reduced in the offspring (p = 0.038, one-tailed t-test). The results suggest that the genetic predisposition to Type 2 diabetes is not associated in young adults with any major pre-morbid impairment in insulin secretion or insulin action but the relationship between the two may be abnormal. Islet A-cell function appears to be normal. 相似文献

Abstract
Obesity is considered a chronic disease requiring treatment. The effect of sibutramine combined with hypocaloric diet and exercise on body weight, body fat mass, lipids, glycemic control, insulin secretion and insulin resistance was evaluated in a randomized, controlled, open-label study. A total of 44 obese type 2 diabetic patients (aged 45.2±5.2 years, BMI 33.62±2.2 kg/m2) and 49 obese nondiabetic subjects (aged 41.9±5.7 years, BMI 34.3±2.6 kg/m2) were treated with sibutramine for 3 months. Moreover, 39 age-matched obese type 2 diabetic patients and 41 obese nondiabetic subjects only on hypocaloric diet and exercise served as control groups. Insulin secretion was estimated during intravenous glucose tolerance test; insulin resistance was assessed by the HOMA index. There was a significant reduction in body weight in both sibutramine-treated diabetic patients (7.1%) and nondiabetic subjects (9.1%), accompanied by a significant reduction in body fat mass. HbA1c decreased significantly in the diabetic patients after sibutramine treatment. There was a significant improvement of lipid parameters in the two groups. Insulin resistance decreased by 21.9% in the sibutramine-treated diabetic patients and by 38.5% in the nondiabetic group. Weight loss was accompanied by an increase of 43.8% in first phase insulin secretion in the sibutramine-treated diabetic group; in the treated nondiabetic subjects there was a decrease in first and second phase insulin secretion and the area under the curve for total insulin secretion. In conclusion, sibutramine leads to a significant reduction in body weight, body fat mass and waist and hip circumferences; it improves insulin sensitivity, insulin secretion, glycaemic control and lipid parameters in both diabetic and nondiabetic obese subjects. 相似文献

目的观察2型糖尿病患者(T2DM)及其一级亲属(FDRs)血浆胆囊收缩素(CCK)水平的变化并分析其相关因素。方法2003-062003-10将河北省人民医院的观察对象分为正常对照组(21例)、FDRs组(35例)、T2DM组(32例),检测受试者体重、空腹胰岛素、空腹血糖及血浆CCK水平变化,对比各组之间生化指标变化。以体重指数(BMI)=25kg/m~2为界限重新分组后进一步分析CCK与BMI的关系。结果血糖、BMI在对照组、FDRs组、T2DM组有逐渐升高趋势,但只在T2DM与对照组间差异有统计学意义(P<0·05)。CCK、胰岛素在对照组、FDRs组、T2DM组逐渐增高,且差异显著(均P<0·01)。以BMI为据分组后,FDRs组、T2DM组BMI>25kg/m~2的受试者胰岛素、CCK水平均明显高于同组BMI<25kg/m~2,血糖差异无显著性。结论T2DM及FDRs血浆CCK水平明显增高,其变化与胰岛素水平变化相似。肥胖可能与CCK、胰岛素水平变化有关。 相似文献

Aims/Introduction
Higher hedonic hunger has been observed in obese individuals compared with those without obesity, but little is known about its association with glycemic management. We aimed to examine the association between hedonic hunger and glycemic control in non‐obese and obese patients with type 2 diabetes.Materials and Methods
Between April and November 2016, a total of 211 type 2 diabetes patients who underwent comprehensive diabetes assessments at a university‐affiliated hospital were recruited into two groups according to body mass index: non‐obese (body mass index 18.5–24.9 kg/m2) and obese (body mass index ≥30 kg/m2) groups. All participants completed the Chinese version of the Power of Food Scale (PFS) for assessment of hedonic hunger. Good glycemic control was defined as glycated hemoglobin <7.0%.Results
Compared with the non‐obese group, the obese group showed higher PFS aggregated and subscale ‘food available’ scores (both P < 0.05). After adjustment for age, sex, disease duration of diabetes and insulin use, there were positive associations of glycated hemoglobin with PFS aggregated, subscale ‘food available’ and ‘food present’ scores in the obese group (all P for trend <0.05). The PFS aggregated score was negatively associated with good glycemic control in obese type 2 diabetes patients after adjustment using logistic regression analysis (adjusted odds ratio 0.42, 95% confidence interval 0.20–0.91, P = 0.027). By contrast, such associations were not observed in non‐obese type 2 diabetes patients.Conclusions
Hedonic hunger had an independent and inverse association with good glycemic control in obese Chinese patients with type 2 diabetes, but not in their counterparts without obesity. 相似文献18.
目的 比较不同血清铁蛋白(SF)水平的新诊断2型糖尿病(T2DM)患者糖、脂代谢及胰岛功能,分析其与SF的关系.方法 以新诊断T2DM患者115例为观察对象,按SF浓度分为高SF组40例(SF≥274.66 μg/L)与正常SF组75例(21.80 μg/L≤SF< 274.66 μg/L).测量两组患者的身高、体重、腰围、臀围,检测空腹血糖、餐后2h血糖(2 hPG)、HbA1c、空腹胰岛素(FINS)、总胆固醇、甘油三酯、高密度脂蛋白-胆固醇(HDL-C)、低密度脂蛋白-胆固醇(LDL-C),计算体重指数、腰臀比、稳态模型评估-胰岛素抵抗指数(HOMA-IR)、稳态模型评估-胰岛β细胞功能指数(HOMA-β)、定量胰岛素敏感性指数(QUICKI)和处置指数,并进行Spearman相关性及多元线性回归分析.结果 高SF组体重指数、FINS、甘油三酯、HOMA-IR高于正常SF组(t=2.470、2.631、2.316、2.879,P均<0.05),HDL-C、QUICKI低于正常SF组(t=-2.030、-2.623,P均<0.05);SF水平与体重指数、腰臀比、空腹血糖、2 hPG、HOMA-IR、甘油三酯均呈正相关(r=0.191 ~0.303,P均<0.05),与HDL-C、QUICKI、处置指数呈负相关(r=-0.221、-0.261、-0.293,P均<0.05);多元线性回归分析显示体重指数、处置指数和甘油三酯是SF的独立相关因素(β=0.041、-0.443、0.270,P均<0.05).结论 高SF水平的新诊断T2DM患者其糖、脂代谢紊乱及胰岛素抵抗程度较正常SF的T2DM患者更严重,SF可能通过增加胰岛素抵抗,促进T2DM的发生和发展. 相似文献
