JAHA:一般人群胰岛素抵抗与左室结构及功能的关系!

2018-03-25 xing.T MedSci原创

由此可见,在基线和随访期间的高胰岛素血症预示着LV功能的恶化和随着时间推移的结构重塑。该研究的发现强调了管理胰岛素抵抗的重要性。

左心室(LV)结构和功能的纵向变化与胰岛素抵抗有关的人群数据较为缺乏。近日,心血管疾病领域权威杂志JAHA上发表了一篇研究文章。研究人员评估了一般人群中高胰岛素血症是否可预测LV和动脉特性的纵向变化。

在627名参与者(平均年龄为50.7岁,51.4%为女性)中,研究人员在基线和4.7年后评估了LV结构和功能的超声指标以及颈股动脉脉搏波速度。研究人员对这些指标的纵向变化与基础胰岛素及其随访变化进行了回归分析,并报告了标准化效应量与胰岛素倍增时LV变化的比例。

调整后,较高的基线胰岛素可预测LV质量指数(效应大小:+15.1%)和E/E′比(+22.1%)增加较大,以及E′峰值和纵向应变(−11.2%至−17.1%)降低程度较大。随访期间胰岛素增加程度较大与较大程度的LV质量指数增加(+10.7%)和射血分数以及纵向应变(−11.4%至−15.7%)减少有关。随访期间成为或保持胰岛素抵抗的参与者经历了更差的纵向应变、E/e′和LV质量指数变化,相比于没有发生或随着时间推移胰岛素抵抗改善的参与者(P≤0.033)。此外,糖尿病患者脉搏波速度的多变量调整增加程度要高于没有糖尿病的患者(1.46米/秒vs. 0.71米/秒;P=0.039)。

由此可见,在基线和随访期间的高胰岛素血症预示着LV功能的恶化和随着时间推移的结构重塑。该研究的发现强调了管理胰岛素抵抗的重要性。

肥胖诱导的代谢疾病涉及几个器官之间通过循环因子的功能整合,但至今为止,我们对肝脏和内脏脂肪组织(VAT)之间的关联还知之甚少。

Am J Gastroenterol:MBOAT7基因的rs626283变异与白种肥胖青年的胰岛素抵抗和脂肪肝有关

MBOAT7基因的rs626283多态性与NAFLD有关,可能通过调节白种人肥胖儿童和青少年的肝内脂肪含量影响葡萄糖代谢

Neurology:中年胰岛素抵抗增加老年阿尔兹海默风险

研究认为,对于无痴呆症状的中年人群,胰岛素抵抗导致老年期间的阿尔兹海默风险增加

Diabetes Obes Metab:补充白藜芦醇对超重和胰岛素抵抗患者肝脏脂肪含量的影响!

总之,这些数据表明白藜芦醇补充剂是安全的,但它不会显著影响人类肝脏脂肪含量和心脏代谢风险参数。

JCEM:miR-181a-5p 和 miR-23a-3p表达变化与肥胖及胰岛素抵抗有关

大家都知道促炎细胞因子TNFα是胰岛素抵抗(IR)的关键因素。虽然一些miRNA被认为与脂肪组织(AT)IR的发展有关,但是miRNA在炎症与IR之间的关联中的作用尚不清楚。Javier Lozano-Bartolomé等人则研究了miR-181a-5p和miR-23a-3p在肥胖中的表达谱并研究它们脂肪细胞中TNFα诱导的IR中作用,并将相关结果发表在近日的JCEM上。
