    摘要 目的：采用16S rRNA高通量测序技术分析柴芪汤对代谢综合征(MS)大鼠肠道菌群的影响。方法：通过Illumina Miseq PE300型高通量测序仪对大鼠粪便肠道菌群进行16S rRNA基因V3-V4可变區检测，运用Usearch、Mothur、LEfSe分析肠道菌群的组成结构及不同菌属相对丰度变化。结果：柴芪汤能够逆转MS大鼠肠道菌群物种多样性的下降，并纠正MS导致的菌群组成结构改变。研究发现MS大鼠的肠道菌群在菌属水平有57个菌属相对丰度发生显著变化，而柴芪汤能将其中的54个菌属恢复至正常水平。结论：从肠道微生态角度阐释了MS的可能病机，柴芪汤可以通过调节肠道菌群防治MS。
