研究问题
This study aimed to evaluate the potential protective effect of medicarpin, a bioactive pterocarpan, against isoflurane-induced cognitive dysfunction.
方法
Anesthesia and/or surgery-induced POCD remains a major issue.
核心结论
We found that medicarpin reduced isoflurane exposure-induced neuroapoptosis, oxidative stress, endoplasmic reticulum stress, and mitochondrial damage in hippocampal tissues and isoflurane-exposed HT22 cells.;The results of this study provide important evidence for developing medicarpin into a potential therapeutic agent for POCD in elderly surgical patients.
