Background: Curcumin, the complex extracted from the traditional edible herb, has a wide range of pharmacological effects. A great deal of studies has demonstrated that curcumin could protect against cerebral ischemia-reperfusion (I/R) injury. In the present study, we aimed to test the hypothesis that curcumin reduces brain damage via regulating mitophagy and preserving mitochondrial function. To clarify the potential Read More

Background: Myocardial Infarction (MI), a kind of heart deficiency, is the main cause of death and disability. Autophagy, a metabolic process for the degradation of damaged proteins or organelles, is important for cardiac functions and regulated by several miRNAs including miRNA- 101. The aim of this research was to investigate the effects of miR-101 in myocardial infarctioninduced injury and the related mechanisms. Methods: Read More

Background: Whether preoperative midline shift and its growing rate are associated with outcomes of decompressive craniectomy in patients with malignant middle cerebral artery infarction is unknown. Methods: We retrospectively included patients: 1) who underwent decompressive craniectomy for malignant middle cerebral artery infarction in West China Hospital from August 2010 to December 2, 2018) who had at Read More

Background: Propofol is an intravenous drug commonly used in anesthesia procedures and intensive care in children. However, it also has neurotoxic effects on children. MicroRNA plays an important role in neurological diseases and neurotoxicity. Methods: In this study, primary rat hippocampal neurons were used to investigate the role of miR- 582-5p in propofol-induced neurotoxicity. Cell viability was monitored by Read More

Background: Curcumin has anti-inflammatory, antioxidant and anticancer properties. Despite the considerable evidence showing that curcumin is an efficacious and safe compound for multiple medicinal benefits, there are some demerits with respect to the therapeutic effectiveness of curcumin, namely, poor stability and solubility, and its role in angiogenesis in vivo is still not yet clear. More recently, the biodegradable Read More

Objective: The effects of mesenchymal stem cell (MSC)-derived exosomes on brain microvascular endothelial cells under oxygen-glucose deprivation (OGD), which mimic cells in deep hypothermic circulatory arrest (DHCA) in vitro, are yet to be studied. Methods: MSCs were co-cultured with primary rat brain endothelial cells, which were then exposed to OGD. Cell viability, apoptosis, the inflammatory factors (IL-1β, IL-6, Read More

Background: Iron homeostasis disorder and neuroinflammation are the most commonly known factors that promote the occurrence and development of cognitive impairment in people. Dexmedetomidine has an anti-inflammatory effect, and it reduces the incidence of postoperative cognitive dysfunction. Therefore, the aim of this study is to verify whether dexmedetomidine could improve lipopolysaccharide-induced i Read More

Background: Reduction in myocardial I/R injury has become the key to the therapy of ischemic cardiovascular disease. Isoflurane (ISO) preconditioning can mimic the major potent protective mechanisms and attenuate ischemia injury. Nevertheless, the mechanisms involved in the cardioprotective effects afforded by isoflurane preconditioning have never been evaluated systematically. Methods: Mice were randomly Read More

Background: People with migraine experience cognitive decline more often than healthy controls, resulting in a significant functional impact. Early identifying influencing factors that contribute to cognitive decline in migraineurs is crucial for timely intervention. Although migraine may onset early in childhood and early onset migraine is related to significant disability, there is no research investigating the association between t Read More

Objective: Early exposure to general anesthesia in children might be a potentially highrisk factor for learning and behavioral disorders. The mechanism of neurotoxicity induced by general anesthesia was not defined. miR-496 could regulate cerebral injury, while the roles of miR- 496 in neurotoxicity were not elucidated. Therefore, we aimed to investigate the effects of miR- 496 in neurotoxicity induced by propofol. Meth Read More

Objective: As a brain-specific microRNA, the mechanism of miR-124 in depression has not been clarified so far. The present study aimed to explore the role of miR-124 in depression and its potential targets. Methods: The depression model was first replicated by the chronic unpredictable mild stress (CUMS) method. miR-124 antagomir was injected into the hippocampus of CUMS rats. Sucrose preference test (SPT), open-field t Read More

Background: Myocardial Fibrosis (MF) is an important physiological change after myocardial infarction (MI). MicroRNA-26b (MiR-26b) has a certain inhibitory effect on pulmonary fibrosis. However, the role of miR-26b in MI-induced MF rats and underlying molecular mechanisms remain unknown. Methods: Forty male Sprague Dawley (SD) rats weighing 200-250 g were divided into four groups (n=10): Sham group, MF group, MF + Read More
