摘要:
背景: 由睡眠限制(SR)引起的肠炎威胁人类健康。但是,肠道炎症条件的根本治疗非常困难。这项研究的重点是褪黑激素对小鼠SR诱导的肠炎和微生物不平衡的影响。
Results: After 20 h of chronic sleep restriction for 28 consecutive days, plasma melatonin was significantly reduced by 48.91% (P<0.05), while GLU, NE, and CORT were significantly increased (34.32%-90.28%, p <0.05。 TNF-α)塑料增加(65.27%-123.26%,p <0.05),whiLE抗炎细胞因子(IL-10和IFN-γ)的水平降低(26.53%-60.41%,p <0.05)。从空肠样品中对16S rRNA的高通量旋转测序表明OTU数量的总体增加(30.68%,p = 0.015)。空肠的α多样性(Shannon,ACE和CHAO1)增加(28.18%-48.95%,p <0.05),β多样性(PCOA和NMDS)与对照组的多样性(PCOA和NMDS)显着差异(p = 0.001)。此外,SR小鼠的螺旋杆菌和梭状芽胞杆菌的患病率较高,而杆菌和乳杆菌的患病率较高(p <0.05)。 However, melatonin supplementation reversed the SR-induced changes and improved oxidative stress, inflammatory response, and microbiota dysbiosis in the jejunum, and there was not significant difference compared with the control group (P>0.05).
Conclusions: Melatonin prevents the SR小鼠肠道菌群的营养不良改善氧化应激和抑制炎症。我们的结果可能为进行睡眠不足而导致人类肠道健康的临床研究提供了理论基础,从而有助于更好地了解褪黑激素的作用。
