甘油三糖 (TyG) 指数有效预测代谢综合征 (MetS) 和相关的心血管风险. 较高的TyG指数水平与炎症和氧化应激增加有关,这解释了2型糖尿病和动脉样硬化心血管疾病的风险.
科学领域:
- 生物化学 生物化学
- 内分泌学 在内分泌学.
- 心血管医学 心血管医学
背景情况:
- 胰岛素抵抗是代谢综合征 (MetS),2型糖尿病 (T2DM) 和动脉样硬化心血管疾病 (ASCVD) 的关键因素.
- 甘油三糖指数 (TyG) 是一种已验证的胰岛素耐药性的测量指标,也是MetS,T2DM,白血病和ASCVD的预测指标.
- 对这些关联的机制性见解是有限的.
研究的目的:
- 调查TyG指数与炎症,氧化应激,自由脂肪酸 (FFA) 水平和阿迪波金失调的生物标志物之间的关系.
- 探索这些协会在对照组和患有新生的MetS.的患者中.
主要方法:
- 研究了一组102名参与者 (59名MetS,43名对照),不包括患有糖尿病,ASCVD,吸烟或宏观炎症的人.
- 采集了禁食血液样本进行血分析和单细胞分离.
- 使用接收器操作特征 (ROC) 曲线分析来评估MetS的TyG指数的预测值.
主要成果:
- 泰格指数显示出MetS的优异预测 (曲线下的面积=0.87) 并与肝脏和脂肪组织的胰岛素抵抗相关.
- 血清RBP-4和非HDL胆固醇水平在TyG指数第三种动物中显著增加.
- 增加的TyG指数与炎症标志物 (CRP,IL-6,化学素,内毒素),氧化应激 (氧化LDL,尼铁素) 和单细胞TLR-4/TLR-2信号的升高显著相关.
结论:
- 泰格指数是MetS和相关心脏代谢风险的强有力的预测指标.
- 一种促炎和促氧化状态,以及高的非HDL胆固醇,可能会机械地将较高的TyG指数与T2DM和ASCVD风险增加联系起来.
