研究问题
To explore whether Jiaotaiwan ameliorates Alzheimer disease (AD) by regulating lipid metabolism via the AMPK pathway.
方法
Twenty 3-month-old male transgenic APP/PS1 mice were randomized equally into two groups for treatment with Jiaotaiwan or normal saline via gavage for 4 weeks, with 10 saline-treated wild-type C57BL/6J mice as the control group.
核心结论
Brain lipid deposition, plasma and brain TC, TG and NEFA levels, and expressions of BACE1, Aβ, p-Tau, ZO-1, occludin, AMPK/p-AMPK, SREBP1, ACC, ATGL, and APOE in the brain tissues were detected.；In the in vitro experiment, PC12 cell co-cultured with mature adipocytes were treated with Jiaotaiwan, AICAR, or both, and the intracellular lipid droplets, TG, NEFA, AMPK activity, and ACC expression were measured.；In the AD mouse models, Jiaotaiwan significantly reduced brain lipid deposits, lowered plasma TC and TG levels, increased plasma NEFA level, and decreased brain TG and NEFA expressions without affecting TC expression.；Jiaotaiwan treatment also significantly lowered the expressions of cerebral Aβ and p-Tau, increased cerebral occludin expression and p-AMPK/AMPK ratio, and reduced ACC, SREBP1 and APOE expressions without affecting ATGL… ‖ 结论：In the APP/PS1 mouse model of AD, Jiaotaiwan alleviates AD-related lipid deposition and dysregulation by activating AMPK and modulating the downstream lipogenic effectors, providing also protective effects on the blood-brain barrier and neural cells.

对本项目的价值
★★★☆☆ 脑老化是最大未满足需求，也是终点最难量化的领域；biomarker 与认知读数选择最敏感。

A 级证据分级：A 级（同行评议人体研究）
本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
