摘　　要：研究不同剂量琥珀酸钠(sodium succinate,SS)对高脂饮食小鼠代谢指标及肠道菌群的改善作用。将32只6周龄C57BL/6J小鼠高脂饮食8周诱导小鼠肥胖模型后,随机分为4组,即高脂饮食组、低剂量、中剂量、高剂量琥珀酸钠组。通过定期记录体重,代谢实验、检测血清血脂四项和促炎细胞因子水平、组织学分析、16S rRNA基因测序等方法来研究琥珀酸钠对高脂饮食小鼠代谢和肠道菌群的影响。结果显示,琥珀酸钠可以减缓高脂饮食小鼠体重的增加,改善血脂和炎症水平、减少附睾白色脂肪细胞的扩张以及棕色脂肪白色化,并且调节了肠道菌群的结构和组成。本研究表明琥珀酸钠通过提高高脂饮食小鼠的呼吸代谢作用增加能量消耗,提高Akkermansia、Peptostreptococcaceae、Allobaculum的相对丰度,降低Lachnospiraceae、Ileibacterium、Desulfovibrionaceae的相对丰度来改善高脂饮食小鼠的代谢紊乱和体重增加。This study aims to investigate the effects of different doses of sodium succinate on metabolic indicators and intestinal flora in mice on a high-fat diet.After inducing obesity in 32 six-week-old C57BL/6J mice with an eight-week high-fat diet,the mice were randomly divided into four groups:a high-fat diet group,and a low-dose,a medium-dose,and a high-dose sodium succinate group.Various methods were carried out to study the effects of sodium succinate on the metabolism and intestinal flora of mice fed a high-fat diet,including regular weight recording,metabolic cage experiments,serum lipid and proinflammatory cytokine level measurements,histological analysis,and 16S rRNA gene sequencing.The results indicate that sodium succinate could slow down the weight gain,decrease blood lipid and inflammation levels,reduce the expansion of epididymal adipose white tissue and the whitening of brown adipose tissue,and regulate the structure and composition of intestinal flora in HFD-fed mice.This study indicates that sodium succinate decreased the metabolic disorders and weight gain in mice fed a high-fat diet by increasing energy expenditure through enhanced respiratory metabolism.It also increased the relative abundance of Akkermansia,Peptostreptococcaceae,and Allobaculum,while decreasing the relative abundance of Lachnospiraceae,Ileibacterium,and Desulfovibrionaceae.
