BMC Med:循环Nrg4水平与代谢综合征有什么关系?

2016-10-27 MedSci MedSci原创

神经调节蛋白4(Nrg4)是一种分泌的脂肪细胞因子,在调节能量代谢系统和肥胖相关疾病的发展中发挥着重要的作用。然而循环NRG4和代谢综合征(MetS)风险之间的联系还是未知的。我们测量了1212肥胖的成年人(40岁以上)的血清Nrg4,这些参与者的腰围大于90厘米(男性)或80厘米(女性)。与健康对照组比较,代谢综合征者有较低的循环Nrg4水平(P < 0.01)。与高循环Nrg4水平的参与

神经调节蛋白4(Nrg4)是一种分泌的脂肪细胞因子,在调节能量代谢系统和肥胖相关疾病的发展中发挥着重要的作用。然而循环NRG4和代谢综合征(MetS)风险之间的联系还是未知的。

我们测量了1212肥胖的成年人(40岁以上)的血清Nrg4,这些参与者的腰围大于90厘米(男性)或80厘米(女性)。

与健康对照组比较,代谢综合征者有较低的循环Nrg4水平(P < 0.01)。与高循环Nrg4水平的参与者比较,低水平的循环Nrg4参与者的代谢综合征患病率较高(67.3 % vs. 57.4 %, P < 0.05)。同样的,低水平的循环Nrg4受试者的空腹血糖和血压升高的患病率较高,但有与甘油三酯升高和HDL-C降低无关。多变量Logistic回归分析显示,增加血清Nrg4与显著降低MetS的风险相关(OR: 0.603; 95 % CI, 0.439–0.828; P = 0.002),校正年龄、性别、吸烟、饮酒、体力活动、体重指数、收缩压、空腹血糖、甘油三酯、高密度脂蛋白胆固醇、胰岛素抵抗指数和身体脂肪量;然而,血清Nrg4与代谢综合征各成分之间没有相关性。

这些结果表明,循环Nrg4浓度与肥胖成人代谢综合征的风险成反比,提示循环Nrg4浓度可能是代谢综合征发展的保护性因素。
