| 1 | 新型小鼠急性脊髓损伤模型的建立与评价显示文摘目的:建立一种操作简单、可重复、稳定的完全急性脊髓损伤(ASCI)动物模型,并对动物神经功能恢复进行初步评价。方法:将27只雌性小鼠随机分为3组(A/B/C),每组9只,钳夹法构建小鼠T9-T11节段ASCI模型,A组为钳夹2秒,B组为钳夹5秒,C组为钳夹10秒,采用改良组织学与行为学方法对模型动物脊髓损伤后神经功能恢复进行评价。结果:小鼠胸椎T9-T1节段急性钳夹损伤后,损伤脊髓处出现明显的出血瘢痕,后组织水肿,髓鞘变性,损伤处上下游出现空泡继而形成瘢痕等一系列的病理变化,3组比较在术后后肢运动功能BMS评分上有统计学差异(p<0.05)。3组术后组织学评分在脊髓损伤程度上有统计学差异(p<0.05)。结论:成功建立稳定性好、重复性强且具有治疗意义的小鼠脊髓钳夹损伤模型;(钳夹5秒组)具备较好的实验价值。 | 赵梓汝 Yan Ao Michael V.Sofroniew 程黎明 | 2015 | 内蒙古科技与经济2015，，20： | 2 |
| 3 | Astrocytes in human central nervous system diseases: a frontier for new therapies显示文摘Astroglia are a broad class of neural parenchymal cells primarily dedicated to homoeostasis and defence of the central nervous system(CNS).Astroglia contribute to the pathophysiology of all neurological and neuropsychiatric disorders in ways that can be either beneficial or detrimental to disorder outcome.Pathophysiological changes in astroglia can be primary or secondary and can result in gain or loss of functions.Astroglia respond to external,non-cell autonomous signals associated with any form of CNS pathology by undergoing complex and variable changes in their structure,molecular expression,and function.In addition,internally driven,cell autonomous changes of astroglial innate properties can lead to CNS pathologies.Astroglial pathophysiology is complex,with different pathophysiological cell states and cell phenotypes that are context-specific and vary with disorder,disorder-stage,comorbidities,age,and sex.Here,we classify astroglial pathophysiology into(i)reactive astrogliosis,(ii)astroglial atrophy with loss of function,(iii)astroglial degeneration and death,and(iv)astrocytopathies characterised by aberrant forms that drive disease.We review astroglial pathophysiology across the spectrum of human CNS diseases and disorders,including neurotrauma,stroke,neuroinfection,autoimmune attack and epilepsy,as well as neurodevelopmental,neurodegenerative,metabolic and neuropsychiatric disorders.Characterising cellular and molecular mechanisms of astroglial pathophysiology represents a new frontier to identify novel therapeutic strategies. | Alexei Verkhratsky Arthur Butt Baoman Li Peter Illes Robert Zorec Alexey Semyanov Yong Tang Michael V.Sofroniew | 2023 | Signal Transduction and Targeted Therapy2023，8，11： | 0 |
