摘要:"Postoperative cognitive dysfunction is a severe neurological complication. How to improve the cognitive impairment caused by sevoflurane, a most common inhaled anesthetic, remains a question worthy of studying. Isovitexin (IVX) is a trihydroxyl flavonoid that is a naturally bioactive ingredient found in various medicinal plants and has antioxidant, anti-inflammatory and neuroprotective properties. The role of IVX in anesthetic-induced nerve injury is rarely reported and the mechanisms are unclear. In this study, we found that IVX improved the cognitive dysfunction induced by sevoflurane in rats. It inhibited sevoflurane-induced cell apoptosis. In addition, IVX increased sevoflurane-induced autophagy in rat brain. Mechanically, IVX activated the PGC-1 alpha/FNDC5 pathway in rat brain, and depletion of FNDC5 could inhibit the neuroprotective function of IVX. In conclusion, our results suggested that IVX restored sevoflurane-induced cognitive dysfunction by mediating autophagy through the activation of the PGC-1 alpha/FNDC5 pathway."
