Eur Heart J:噪声对血管功能、氧化应激和炎症的影响

2017-02-20 xing.T MedSci原创

由此可见,该研究建立了一个新的独特的飞机噪声应激模型,增加的血压和血管功能障碍与氧化应激有关。这种动物模型可以进一步研究分子机制、缓解策略和药理干预,以防止噪声引起的血管损伤。

流行病学研究表明交通噪声会增加冠状动脉疾病、高血压和脑卒中的发病率。其潜在机制仍然未知。夜间噪声暴露的现场研究表明飞机噪声导致血管功能障碍,而且这些改变可以被维生素C所改善,提示氧化应激中这种现象中发挥了关键作用。近日,有研究人员针对这一问题在心血管领域权威杂志Eur Heart J上发表了一篇研究文章。

研究人员开发了一种新的动物模型来研究飞机噪声暴露对血管的影响。用扬声器提供高峰达85分贝和平均为72分贝4天可以引起收缩压、血浆去甲肾上腺素和血管紧张素II水平升高,并且诱导内皮功能障碍。噪声增加eNOS的表达,由于eNOS解偶联而降低血管NO水平。噪声增加循环中硝基酪氨酸和白细胞介素-6水平,并且增加血管NADPH氧化酶亚基NOX2、硝基酪氨酸阳性蛋白和内皮素-1的表达。流式细胞仪分析表明自然杀伤细胞和中性粒细胞浸润到血管的数量增加。为期4天的相同平均声压水平的白色噪声并没有引起这些变化。将飞机噪声处理动物的主动脉组织进行对比Illumina转录组测序显示部分负责调节血管功能、血管重构和细胞死亡的转录基因显著变化。

由此可见,该研究建立了一个新的独特的飞机噪声应激模型,增加的血压和血管功能障碍与氧化应激有关。这种动物模型可以进一步研究分子机制、缓解策略和药理干预,以防止噪声引起的血管损伤。

自闭症与视觉噪声敏感性

一项研究发现,自闭症谱系障碍的某些知觉削弱可能与对感官噪声的敏感性增加有关,而非与感官整合的缺损有关。患自闭症的人们常常表现出在涉及对单个元素的感知的任务中取得的成绩高,而在需要全局感知的任务中取得的成绩低,这种现象常常被归结于缺少全局感觉整合。为了检验另外一种假说,即患自闭症的人对噪声感官信号具有高敏感度,Adam Zaidel及其同事向14位患自闭症的人提供了具有不同难度的一个视觉感知任务,在
