Sevoflurane anesthesia represses neurogenesis of hippocampus neural stem cells via regulating microRNA-183-mediated NR4A2 in newborn rats.

Sevoflurane has been commonly utilized in nonobstetric surgeries in pregnant women, and its impacts on fetal brain are still not completely known. Ectopic NR4A2 expression has been reported to be related with familial Parkinson disease, and through dual luciferase we found that NR4A2 is a target gene of microRNA-183 (miR-183). We proposed a hypothesis that miR-183 may participate in the process by targeting NR4A2 in neurons after sevoflurane anesthesia.

Protective effect of notoginsenoside R1 in a rat model of myocardial ischemia reperfusion injury by regulation of Vitamin D3 upregulated protein 1/NF-κB pathway.

The aim of this study was to investigate the protective effects of notoginsenoside R1 (R1) in the rat model of myocardial ischemia reperfusion injury and the possible mechanisms. Myocardial ischemia/reperfusion injury (MIRI) was induced by ischemia for 30 min and reperfusion for 60 min. Fifty male SD rats (250-300 g), were randomly divided into 5 groups: sham, model, R1 (20 mg/kg, 40 mg/kg, 60 mg/kg).
