There has been increasing interest in the connection between AD, gut microbiota, and metabolites. Kai-Xin-San (KXS) has been commonly employed in ancient and modern Chinese clinical trials for the treatment of dementia; however, whether the protective effect of KXS in AD is related to the gut microbiota remains elusive. APP/PS1 mice were used as the model of AD. 43 key metabolites influenced by KXS were screened using untargeted metabolomics. At the genus level, Clostridium_IV, Eubacterium, Acetatifactor, etc., were identified to be impacted by KXS using 16S rRNA sequencing. Additionally, we identified 9 distinct intestinal floras at the genus level that were correlated with 13 pivotal differential metabolites related to cognitive impairment. KXS also inhibited the neuroinflammation, mostly via regulating the key metabolites. A potential relationship between gut microbiota, metabolites, and neuroinflammation is suggested as a protective mechanism of KXS in AD. These findings provide support for further development of KXS.
人们对阿尔茨海默病（AD）、肠道微生物群和代谢物之间的联系越来越感兴趣。开心散（KXS）在古代和现代中国临床试验中一直被广泛用于治疗痴呆症；然而，KXS对AD的保护作用是否与肠道微生物群有关仍不清楚。以APP/PS1小鼠作为AD模型。使用非靶向代谢组学筛选出43种受KXS影响的关键代谢物。在属水平上，利用16S rRNA测序确定KXS会影响IV型梭菌、真杆菌、乙酸杆菌等。此外，我们在属水平上鉴定出9种不同的肠道菌群，它们与13种与认知障碍相关的关键差异代谢物相关。KXS还主要通过调节关键代谢物来抑制神经炎症。肠道微生物群、代谢物和神经炎症之间的潜在关系被认为是KXS在AD中的一种保护机制。这些发现为KXS的进一步开发提供了支持。
