Abstract： 目的:探讨Graves病患者治疗前在葡萄糖负荷(OGTT)时血清脑肠肽(Ghrelin)水平的变化.方法:对36例初诊Graves病患者,葡萄糖氧化酶法测定血浆血糖(PG)、放射免疫分析胰岛素(INS)及血清Ghrelin;计算胰岛素敏感性指数(ISI)、胰岛素抵抗指数(IR);30例健康成人作为正常对照组.结果:①Graves病患者治疗前腰围、体重、BMI、ISI明显低于正常对照组(P<0.05);②治疗前空腹血糖(fPG)、空腹胰岛素(fINS)、IR高于正常对照组(P<0.05);空腹血清Ghrelin水平(998±194) pg/ml,明显低于正常对照组(1241±225) pg/ml(P<0.01);但两组在餐后30min、60min和120min的Ghrelin水平无明显差异(P>0.05);③Graves病患者治疗前空腹血清Ghrelin水平与fINS呈负相关(r=-0.476,P<0.05);其它时间点的Ghrelin与INS均无相关性.结论:Ghrelin可能参与了Graves病的发生和发展.
