  • 简介:AbstractMany factors can cause inner ear injury, such as noise exposure, chemicals, viral infection, and radiation. The main pathological manifestations of inner ear injury are local hypoxia-ischemia, micro-trauma, and an increased level of reactive oxygen species and inflammatory mediators. The contribution of the inflammatory response to the mediation of cochlear and vestibular pathologies has received increasing attention in recent years. Aseptic inflammation can devastate audition and balance, which can lead to many typical clinical inner ear diseases. In this review, we will discuss the most pertinent and recent research on inflammatory mechanisms in inner ear injury. We will also discuss the pathophysiology of some common and significant ear diseases, such as sudden sensorineural hearing loss, age-related hearing loss, noise-induced hearing loss, and Meniere’s disease.

  • 简介:AbstractWith the deepening of research, proteomics has developed into a science covering the study of all the structural and functional characteristics of proteins and the dynamic change rules. The essence of various biological activities is revealed from the perspectives of the biological structure, functional activity and corresponding regulatory mechanism of proteins by proteomics. Among them, phospholipid-binding protein is one of the hotspots of proteomics, especially annexin A1, which is widely present in various tissues and cells of the body. It has the capability of binding to phospholipid membranes reversibly in a calcium ion dependent manner. In order to provide possible research ideas for researchers, who are interested in this protein, the biological effects of annexin A1, such as inflammatory regulation, cell signal transduction, cell proliferation, differentiation and apoptosis are described in this paper.
