Résumé
Objective The traditional round incision or cross incision brain harvesting method can not meet the requirements of protecting the donor's remains. In this study, the method of brain removal through a posterior incision on the scalp of both ears was proposed, which effectively protected the donor's remains. Methods Adopting the incision 2. 0 cm above the external occipital protuberance to the most front edge of the auricle to obtain a complete brain. Results The incision did not involve the head and face skin, which was small and conducive to suture repair and reduce exudation. Conclusion The incision effectively protects the donor' s remains, and it will be conducive to the establishment and development of the brain bank.

[Abstract] Objective To investigate the role of dihydromyricetin (DHM) in the treatment of ischemic stroke in rats, and to explore the effect of DHM on the expression of inflammasome. Methods The middle cerebral artery occlusion (MCAO) model was induced by endovascular suture method. The therapeutic effect and mechanism of DHM were investigated by Longa score, TTC staining, Nissl staining, immunohistochemical staining and Western bloting. Results After DHM treatment, the motor capacity of MCAO rats was significantly improved, the infarct volume was significantly reduced, the brain structure and neuron morphology were improved, and the expressions of nod-like receptor protein-3 (NLRP3) and interleukin-1(IL-1) decreased significantly. Conclusion DHM can down-regulate the expression of NLRP3 and thus reduces the cerebral infarction volume and improves neurobehavioral performance in MCAO rats.
