摘要:

旨在探究无柄灵芝醇提物(Ganoderma resinaceum alcohol extract,GRAE)对小鼠睡眠和肠道菌群的影响,分析肠道菌群与睡眠之间的联系。连续灌胃30 d,观察戊巴比妥钠诱导下小鼠的入睡率和睡眠时长,观察巴比妥钠诱导下小鼠的睡眠潜伏期。检测小鼠的血清,采用16S rDNA测序分析GRAE对小鼠肠道菌群丰度的影响。结果表明,GRAE延长戊巴比妥钠诱导下小鼠的睡眠时长,增加戊巴比妥钠阈下剂量催眠下小鼠的入睡率,缩短巴比妥钠诱导下小鼠的睡眠潜伏期,降低小鼠血清中血糖和甘油三脂的含量。16S rDNA结果表明,在门水平上,GRAE增加了拟杆菌门和放线菌门的菌群丰度;在属水平上,GRAE增加双歧杆菌属的菌群丰度,减少乳酸菌属和克雷伯氏菌属的菌群丰度。因此,GRAE能调节肠道菌群的丰度影响小鼠的睡眠质量。

Abstract:

The aim of this study is to investigate the effects of Ganoderma resinaceum alcohol extract(GRAE)on sleep and intestinal microbiota in mice,and to analyze the association between intestinal microbiota and sleep. The sleep rate and sleep duration of mice under sodium pentobarbital induction were observed by continuously gavaging for 30 d,and the sleep latency of mice induced by sodium barbiturate was observed. The serum of mice was tested and the effect of GRAE on the abundance of intestinal microbiota in the mice was analyzed by 16S rDNA sequencing. The results showed that GRAE prolonged the sleep duration of mice induced by sodium pentobarbital,increased the sleep rate of mice hypnotized by pentobarbital sodium subthreshold dose,shortened the sleep latency of mice induced by sodium pentobarbital,and decreased the serum levels of glucose(GLU)and triglyceride(TG)in mice. 16S rDNA results showed that GRAE increased the abundance of Bacteroidetes and Actinobacteria at the phylum level;at the genus level,GRAE increased the abundance of Bifidobacterium,and decreased the abundance of Lactobacillus and Klebsiella. Therefore,GRAE can regulate the abundance of intestinal microbiota,which in turn affects the sleep quality of mice.
