研究问题
With global population aging accelerating, identifying safe and effective anti‐aging interventions has become a major challenge (Dong et al. ; Jiang et al. ).；However, aging involves coordinated multi‐system changes that cannot be captured by single‐molecule or single‐pathway approaches, limiting our understanding of the holistic regulatory effects of natural products.；The present study extends this work by examining whether POP treatment is accompanied by changes in gut bacterial composition, circulating metabolites, and hippocampal and colonic gene expression within the same experimental framework.
方法
Eight‐week‐old male C57BL/6 mice were purchased from Hunan SJA Laboratory Animal Co.；The mice were randomly assigned to three groups (n = 10): Control, Model, POP.；Fecal and serum samples from each group were used for 16S rRNA sequencing (n = 6) and untargeted metabolomic (n = 5) detection, respectively.；Hippocampal and colonic samples from each group were used for transcriptomic (n = 3) and quantitative real‐time polymerase chain reaction (PCR) analysis (n = 3).
核心结论
Additionally, neuronal swelling, nuclear pyknosis, a significant decrease in the number of Nissl bodies and nuclei, irregular alignment, and pale staining were observed.；In contrast, the mice in the POP group showed improvements compared to those in the Model group, with neuronal recovery, a more orderly arrangement, increased numbers of Nissl bodies and nuclei, relatively regular structure, and deeper, clearer staining.；These findings suggest that POP alleviates D‐galactose‐induced neuronal damage in the brain. ‖ 结论：These findings identify candidate gut–serum–tissue associations for further investigation.
局限
An association with Chrdl2 was also observed using the RNA‐seq data, but this finding should be interpreted cautiously because the group difference in Chrdl2 expression was not confirmed by RT‐qPCR.；In particular, the eight‐week model may not reflect the long‐term succession of gut microbial communities or the chronic inflammatory changes that develop during natural aging.；However, these correlations do not establish directionality or causality.
对本项目的价值
★☆☆☆☆ 菌群是可远程部署、成本最低的干预变量，但因果性与个体化响应仍是主要瓶颈。

本文核心结论来自动物模型或体外细胞学，属临床前证据，不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义，与人类临床结局之间仍有距离。
