          摘  要  目的  探讨蒲公英总黄酮通过调控肠道菌群对高脂饮食诱导的小鼠肥胖的抑制作用机制。方法  将24只C57BL/6J小鼠
          随机分为空白组、模型组和蒲公英总黄酮组,每组8只。除空白组外,其余两组小鼠予以高脂饮食饲养,同时蒲公英总黄酮组小鼠
          予蒲公英总黄酮[400 mg/(kg·d)]灌胃,每天1次,连续8周。实验期间,记录每组小鼠的采食量。末次给药后,对小鼠的体重、脂肪
          质量、血脂水平及肝脏和附睾脂肪病理变化进行评价,观察蒲公英总黄酮对小鼠肥胖的治疗效果;通过扩增子测序检测小鼠肠道
          菌群丰度及结构的变化;利用实时荧光定量PCR技术分析蒲公英总黄酮对小鼠脂肪代谢相关基因的影响。结果  与模型组比较,
          蒲公英总黄酮组小鼠的体重显著降低(P<0.05);血清总胆固醇、甘油三酯、低密度脂蛋白胆固醇水平均显著降低(P<0.01),高密
          度脂蛋白胆固醇水平显著升高(P<0.01);腹股沟白色脂肪组织和附睾白色脂肪组织的脂肪指数均显著降低(P<0.05);肝细胞脂
          肪变性及脂肪细胞病变明显改善;细胞色素c氧化酶亚基7A1和细胞色素c氧化酶亚基8B mRNA的表达均显著上调(P<0.05)。
          菌群检测结果显示,与模型组比较,蒲公英总黄酮组小鼠的菌群多样性有上升趋势,Sobs指数和β多样性均显著升高(P<0.05);
          经黏液真杆菌属 Blautia、norank_f_Ruminococcaceae、嗜胆菌属 Bilophila、另枝菌属 Alistipes、classi-fied_f_Ruminococcaceae、副拟
          杆菌属 Parabacteroides、norank_f_Desulfovibrionaceae、厌氧短杆菌属 Anaerotruncus 的菌群相对丰度显著升高(P<0.05),粪杆
          菌 属 Faecalibaculum、丹 毒 梭 菌 属 Erysipelatoclostridium、GCA-900066575、梭 菌 属 Tuzzerella、乳 杆 菌 属 Lactobacillus、
          norank_f_norank_o_RF39、achnospiraceae_FCS020_group的菌群相对丰度显著下降(P<0.05)。结论  蒲公英总黄酮能降低肥胖小
          鼠的体重、脂肪质量与血脂水平,修复肥胖小鼠肝脏及附睾脂肪的病理损伤,这一作用与其改善因高脂饮食导致的肠道菌群紊乱
          有关。

          ABSTRACT   OBJECTIVE To investigate the mechanism of the inhibitory effect of total flavonoids from Taraxacum mongolicum
          on  high-fat  diet-induced  obesity  in  mice  through  modulation  of  intestinal  flora.  METHODS  Twenty-four  C57BL/6J  mice  were
          randomly divided into blank group, model group and T. mongolicum total flavonoid group, with 8 mice in each group. Except for
          the blank group, the other 2 groups were given a high-fat diet, while T. mongolicum total flavonoid group was given T. mongolicum
          total  flavonoid  [400  mg/(kg·d)]  intragastrically,  once  a  day,  for  8  consecutive  weeks.  During  the  experiment,  the  food  intake  of
          each group of mice was recorded. After the last medication, the body mass, fat weight, blood lipid level and pathological changes
          of liver and epididymal fat in mice were evaluated to observe the effect of T. mongolicum total flavonoid on the treatment of obesity
          in mice. The changes in abundance and structure of intestinal flora in mice were detected by amplicon sequencing; the effects of T.
          mongolicum total flavonoids on fat metabolism related genes were analyzed by qPCR. RESULTS Compared with model group, the
                                                             body  weight  of  mice  in  T.  mongolicum  total  flavonoids  group
