PPARG and type 2 diabetes mellitus: Other studies have explored the relationship between EA and peroxisome proliferators-activated receptors γ (PPARγ) in patients with Alzheimer's disease (AD) and type 2 diabetes mellitus (DM2) [8, 9]; thus, it is important to explore the role of PPARγ in the process of ARDS and its crucial role in the EA treatment of ARDS.
