摘要
目的 探讨代谢综合征（MS）患者葡萄糖代谢率与血浆脂联素、瘦素水平的关系.方法 筛选30例MS患者和20名健康者为对照组.所有受试者均行高胰岛素-正常血糖钳夹试验;检测血浆脂联素与瘦素浓度及空腹胰岛素（FTNS）、血糖、血脂等生化指标;测定血压、腰围、身高、体重等人体参数.结果 （1）高胰岛素-正常血糖钳夹试验稳态时（120～150 min）,MS组的葡萄糖代谢率显著低于对照组[（8.33±1.59）与（4.13±1.34）mg·kg^-1·min^-1],差异有统计学意义（P＜0.01）.（2）MS组的血浆脂联素水平显著低于对照组[（5.15±2.54）mg/L比（10.28±5.50）mg/L,P＜0.01],瘦素水平显著高于对照组[（189±90）μg/L比（127±73）μg/L,P＜0.01].（3）在MS组,腰围、体质指数、甘油三酯、高密度脂蛋白胆固醇、FINS、脂联素、瘦素等与葡萄糖代谢率相关（均P＜0.05）.结论 提示MS患者的胰岛素抵抗可能与血浆脂联素降低及瘦素升高有关.
Objective To investigate the relationship of glucose metabolic rate （GMR） and plasma levels of adiponectin and leptin in patients with metabolic syndrome （MS）. Methods A total of 30 MS subjects aged 36 -60 years old were selected as MS group. And 20 normal adults were selected as control group. The GMR was evaluated by the technique of hyperinsulinemic euglycemia clamp. The plasma concentrations of adiponectin and leptin were detected by enzyme-linked immunosorbent assay （ELISA）. Blood pressure, waist circumference （WC）, body weight and body height were measured.Results （ 1 ） During the steady state （ last 30 min）, the GMR was significantly lower in MS group than that in control Group [ （4. 13 ± 1.34） mg· kg^- 1 · min^ -1 vs （ 8.33 ± 1.59 ） mg · kg^- 1 · min^ -1, P 〈 0. 01 ].（2） The plasma level of adiponectin was significantly lower in MS group than that in control group [ （5. 15 ±2. 54） μg/ml vs （ 10. 28 ±5.50 ） μg/ml, P 〈0. 01 ]. The plasma level of leptin were significantly higher in MS group than that in control group [（189.37 ±90.48） nng/ml vs（126.55 ±72.70） ng/ml, P 〈0.01].（3） In MS group, glucose metabolic rate was associated with WC, BMI, TG, HDL-C FINS, leptin, and adiponectin, （ all P 〈 0. 05 ）. Conclusion The technique of hyperinsulinemic euglycemic clamp shows that the BMR of MS patients significantly decreases. It may be associated with their lowered plasma levels of adiponectin and leptin.
