Ocular neuromyotonia (ONM) is a rare ocular motility disorder characterized by involuntary contraction of extraocular muscles resulting in intermittent diplopia.ONM is reported as a rare complication after radiotherapy,however,there are a few cases of ocular neuromyotonia in the absence of irradiation [1-5].Here we report a patient with right carotid artery stenosis and intermittent diplopia.24 years ago,the patient has right tonsillar cancer and had received radiotherapy.Therefore,the patient was diagnosed as having post-radiation carotid artery stenosis and ONM.Post-radiation carotid artery stenosis and intermittent diplopia may indicate ONM.

目的 本实验室前期利用乙酰胆碱酯酶(AChE)和丁酰胆碱酯酶(BuChE)抑制剂高通量筛选模型,筛选出了具有较高乙、丁酰胆碱酯酶抑制活性的化合物DL0410,其药效得到东莨菪碱诱导的小鼠学习记忆障碍模型的验证。方法 本文利用APP/PS1转基因小鼠模型评价了DL0410的抗AD作用。多项行为学实验结果均表明,DL0410可明显改善模型小鼠的学习记忆能力,药效优于阳性药美金刚和多奈哌齐。结果 病理切
背景及目的 脑卒中以其高发病率、高病死率和高致残率严重影响着人类的健康,给社会和家庭带来沉重的负担.全球每年有600万的新发脑卒中患者,而其中87%为缺血性脑卒中[1],尽管进行了大量的基础和临床研究,目前美国FDA仅批准r-tPA溶栓作为脑梗死急性期的治疗[2].亚急性期和慢性期患者除了支持和康复治疗外,尚无有效的治疗方法.如何有效保护脑细胞、恢复脑血流,促进血管神经再生,改善神经功能仍然是缺血
