Retinal degeneration is a debilitating ocular complication characterized by the progressive loss of photoreceptors and other retinal neurons,which are caused by a group of retinal diseases affecting various age groups,and increasingly prevalent in the elderly.Age-related macular degeneration,diabetic retinopathy and glaucoma are among the most common complex degenerative retinal disorders,posing significant public health problems worldwide largely due to the aging society and the lack of effective therapeutics.Whilst pathoetiologies vary,if left untreated,loss of retinal neurons can result in an acquired degeneration and ultimately severe visual impairment.Irrespective of underlined etiology,loss of neurons and supporting cells including retinal pigment epithelium,microvascular endothelium,and glia,converges as the common endpoint of retinal degeneration and therefore discovery or repurposing of therapies to protect retinal neurons directly or indirectly are under intensive investigation.This review overviews recent developments of potential neuroprotectants including neuropeptides,exosomes,mitochondrial-derived peptides,complement inhibitors,senolytics,autophagy enhancers and antioxidants either still experimentally or in clinical trials.Effective treatments that possess direct or indirect neuroprotective properties would significantly lift the burden of visual handicap.

教师的职责是教书育人,课程思政让育人工作更系统化,更有针对性.将传统的思政教育对接专业课程,实现专业课与思想政治理论课同向同行,达到“以文化人、以文育人”的全方位“课程思政”目标.本草文化中蕴含着丰富的德育元素和人文精神,教师应该在临床中药学的教学过程中充分发挥价值引导、情感传递和道德示范作用.本文以临床中药学课程为例,积极探索实施课程思政的具体措施,分别从教学目标、教学内容、教学评价、教学成果、教学反思几方面进行课程思政教学改革的探讨,力求将专业课与德育教育有机融合,充分发挥专业课的育人功能.

Neurodegenerative brain disorders are a major burden in our society,such as Alzheimer\'s disease.In order to repair or prevent such diseases,drugs are designed which enter the brain,but the blood-brain barrier limits their entry and the search for alter

Numerous molecular mechanisms are being examined in an attempt to discover disease-modifying drugs to slow down the underlying neurodegeneration in Alzheimer\'s disease.Recent studies have shown the beneficial effects of epidermal growth factor receptor
