正在多发性硬化(MS)等经典神经系统免疫性疾病中,获得性自身免疫反应首先在外周被激活,随后靶向攻击神经系统而致病。随着研究的深入,学者发现脑血管病[如脑卒中、蛛网膜下腔出血(SAH)]、神经变性病[如阿尔茨海默病(AD)、运动神经元病(MND)、帕金森病(PD)]、癫、自身免疫性脑炎(AE)、神经系统遗传性疾病、周围神经病、神经肌肉病等几乎所有神经系统疾病的发生与发展均有免疫机制参与,免疫因素致病现已成为神经系统疾病研究的热点,针对神经系统疾病免疫机制的治疗策略研究及转化研究如雨后春笋不断涌现。  相似文献

中枢神经系统自身免疫性疾病是以自身免疫细胞、自身抗体及其他免疫分子直接或间接攻击神经系统(包括神经元、胶质细胞、髓鞘)为主要致病机制的自身免疫性疾病。这一类疾病的早期鉴别诊断、疾病进展监测以及疗效预后评估等很大程度上依赖于实验室辅助检查。而国内中枢神经系统自身抗体检测方法学的选择和判读依据尚缺乏适合的标准或指导性规范, 迫切需要规范实验室诊断以更好地指导临床实践。为此, 中华医学会神经病学分会神经免疫学组基于国内外抗体检测技术进展和临床诊断需求, 并在充分征求学组专家意见的基础上形成了"中枢神经系统自身免疫性疾病相关抗体检测专家共识2022"。本共识总结常见的中枢神经系统自身免疫性疾病(以中枢神经系统炎性脱髓鞘疾病和自身免疫性脑炎为例)实验室辅助检查的原理和传统检测方法, 对如何选择实验检查项目以及解读实验室检查的结果给出指导性建议。  相似文献

Summary Beginning from the observation that Scots living in England have much higher rates of mental hospital admission than do the English, several hypotheses are proposed to account for this. Much of the excess in rates of mental illness is accounted for by those diagnosed as having alcohol-related disorders and behaviour and personality problems. The results of an examination of offical statistics in the two countries enabled some explanations to be offered. It was found that rates of admissions to mental hospitals are higher in Scotland than in England but not as high as those found among Scots migrants who have a much higher rate of readmission to hospitals than either of the other groups. In fact, if first admissions only are considered the rates of admission in Scotland are not only higher than rates for English natives but also higher than for Scottish migrants. It seems that Scots living in England are somewhat less likely to become mental patients than Scots in Scotland but that once they do achieve this status they are very much more likely to be readmitted on subsequent occasions. It was concluded that there might be two fairly distinct groups of migrants from Scotland to England who have different backgrounds, different reasons for migrating and different psychological characteristics. On the one hand there are stable, economically motivated migrants who move south for definite employment related reasons and who show few psychological symptoms. While on the other hand there is a group of migrants who perhaps have psychological problems and who move more in hope than expectation without definite prospects and who account for the high rates of mental hospital admission found in Scottish migrants.  相似文献

Prostacyclin release from rat isolated perfused hearts and from dog coronary circulation was studied by measuring immunoreactive 6-keto-PGF1 alpha (6-keto-PGF1a) in heart perfusate and in plasma obtained from the great cardiac vein respectively. Continuous infusion of arachidonic acid at constant concentration in isolated perfused hearts induced an increased prostacyclin release. This release showed a rapid peak within 10 min and a subsequent decrease. Low-flow ischemia induced an increased perfusate concentration of 6-keto-PGF1a but, considering the decreased flow, prostacyclin release was actually reduced. During the whole period of ischemia (60 min) prostacyclin release was constant. In open-chest anesthetized dogs 6-keto-PGF1a concentration in the great cardiac vein was increased after ligation of the left anterior descending coronary artery. A prolonged period of coronary occlusion (4.5 hours) resulted in a progressive rise of prostacyclin release. 6-keto-PGF1a determinations in the femoral vein and in the aorta did not show relevant variations during the observation period.  相似文献

抑郁是癫痫患者中常见的精神障碍,严重地影响了患者的生活质量。传统的观点认为癫痫患者因为存在着诸多社会学问题易出现抑郁倾向,癫痫和抑郁是单向的联系,但大量的研究已经证明癫痫和抑郁之间存在双向的联系,一种异常状态的存在可能易转化为另一种异常状态的发展。癫痫和抑郁存在着共同的发病机制。本文主要就癫痫和抑郁的双向联系以及抗抑郁药物在癫痫患者中的应用进行阐述。  相似文献

Epilepsy is a major public health problem in many tropical countries. Also, some of the tropical diseases are major contributors to the higher prevalence of epilepsy in these countries. The etiologic factors responsible for epilepsy in these countries are quite different from those in the developed world. This article discusses the etiologic factors and neuroimaging of epilepsy in light of the conditions in these tropical countries.  相似文献

Increase in cathepsin D activity in rat brain in aging   总被引:5,自引:0,他引:5  
Cathepsin D-like activity in homogenates of five brain areas of 3-month-old and 24-month-old Fischer 344 rats was measured. With hemoglobin as substrate at pH 3.2, more than 90% of the activity was inhibited by pepstatin. In each area studied, activity was more than twice as high in the old rat brain: 140-160% higher in the cortex, cerebellum, pons-medulla, and striatum and 90-100% higher in the hippocampus and spinal cord. The greatly increased metabolic capacity in the absence of an increase in protein turnover may have a role in age-related pathological degeneration in the brain.  相似文献
