一、不良环境因素构成反社会人格障碍的危险因素证明力度最强的是大样本双生子研究。
最近发表的该类研究证实环境在反社会人格障碍发展中起到不可忽视的重要作用。
Kendler等[1]使用美国精神障碍诊断和统计手册第四版的反社会人格障碍诊断标准症状数量指标,对1492对双胞胎的行为遗传学研究发现,环境因素对反社会人格障碍的贡献率是59.1%。
研究还发现环境因素反映了DSM IV的A、B、C分类学,某些环境因素(如儿童虐待)是多种人格障碍的共同危险因子,因而增加人格障碍的共病;而遗传因素并没有反映出DSM IV的人格障碍的分类。
另外一项双生子研究来自挪威,这个项目研究了1386对19到35岁的挪威双生子DSM IV的B族人格障碍,也发现环境因素对反社会人格障碍形成有相似但稍小的作用[2]。
明尼苏达双生子家庭研究对1315对17岁双胞胎进行了不良环境因素的调查和遗传危险因子的研究,量表测量的四大项不良环境因素包括学业成绩、与反社会行为相关的同伴附着度、父母与孩子关系、生活事件压力。
一致性地发现在每一个不良环境因素下,都会增加外显行为罹患的几率;在不良的环境中,遗传危险因子的作用变得更加突出;环境因素的致病作用机制某种程度上存在着共同的途径[3]。
作文你对神经病的了解英文回答:Neurological disorders, commonly known as mental illnesses, are medical conditions that affect the brain and the nervous system. These disorders can cause a wide range of symptoms, including changes in mood, behavior, and cognitive functioning. There are many different types of neurological disorders, including depression, anxiety disorders, schizophrenia, bipolar disorder, and Alzheimer's disease.Neurological disorders can have a significant impact on a person's daily life, making it difficult for them to function normally. They can affect a person's ability to think, feel, and behave in a rational and coherent manner. These disorders can also affect a person's relationships, work performance, and overall quality of life.The causes of neurological disorders are complex andcan vary from person to person. Some neurological disorders have a genetic component, meaning that they can be passed down from one generation to the next. Other factors, such as environmental factors, traumatic experiences, and chemical imbalances in the brain, can also contribute to the development of these disorders.Treatment for neurological disorders often involves a combination of medication, therapy, and lifestyle changes. Medications can help to alleviate symptoms and stabilize mood, while therapy can help individuals develop coping strategies and improve their overall mental well-being. Lifestyle changes, such as maintaining a healthy diet, getting regular exercise, and practicing stress management techniques, can also be beneficial in managing neurological disorders.In conclusion, neurological disorders are complex medical conditions that affect the brain and the nervous system. They can have a significant impact on a person's daily life and require comprehensive treatment. With the right support and treatment, individuals with neurologicaldisorders can lead fulfilling and productive lives.中文回答:神经病,通常被称为精神疾病,是一种影响大脑和神经系统的医学疾病。

羊毛固醇合成酶(LSS)功能缺失对C57BL-6J小鼠进修记忆能力的影响羊毛固醇(cholesterol)是维持细胞膜结构和调整神经信号传导的重要组成部分。
羊毛固醇固醇合成酶(LSS)是羊毛固醇生合成途径中的关键酶,但其在中枢神经系统中的作用尚不清晰。
本探究旨在探究LSS功能缺失对C57BL/6J小鼠进修记忆能力的影响。
通过建立LSS敲除小鼠模型,在Morris水迷宫中测试LSS敲除小鼠的空间记忆能力。
结果表明,LSS敲除小鼠在Morris水迷宫测试中表现出更弱的空间记忆能力,进修曲线较平缓,而野生型小鼠则表现出更好的空间定位和探究行为。
这些结果提示LSS功能缺失可能会影响中枢神经系统的生理功能,从而影响记忆形成和进修能力。
关键词:羊毛固醇固醇合成酶, C57BL/6J小鼠,进修记忆,Morris水迷宫Abstract:Cholesterol is an essential component of cell membrane structure and regulates neuronal signaling transmission. Lanosterol synthase (LSS) is a critical enzyme in the cholesterol biosynthesis pathway, butits function in the central nervous system is unclear.This study aims to investigate the effect of LSS deficiency on learning and memory ability in C57BL/6J mice. By establishing LSS knockout mouse model,spatial memory ability is tested in Morris water maze. The results show that LSS knockout mice exhibit weaker spatial memory ability in Morris water maze, with a flatter learning curve, while wild-type mice showbetter spatial orientation and exploration behavior. These results suggest that LSS deficiency may affect the physiological function of the central nervous system, thereby affecting memory formation andlearning ability.Keywords: lanosterol synthase, C57BL/6J mice, learning and memory, Morris water mazThe Morris water maze is a widely used behavioral test in neuroscience research to evaluate learning and memory abilities in rodents. The test involves placing the animal in a circular pool filled with opaque water, and the animal must swim and find a hidden platform to escape the water. The animal's ability to find the platform is used as an index of spatial memory and learning ability.In the present study, the focus was on the role of lanosterol synthase (LSS) in learning and memory. LSSis an enzyme that is essential for the synthesis of cholesterol in the body. Previous research has suggested that cholesterol and its biosynthesis intermediates are involved in neuronal function and synaptic plasticity. Therefore, it was hypothesized that LSS deficiency may affect memory and learning abilities.The results of the Morris water maze test showed that LSS knockout mice performed poorly compared to wild-type mice. The knockout mice exhibited a flatter learning curve, which suggests that they haddifficulty learning the task. In contrast, the wild-type mice showed better exploration behavior and were able to find the platform more quickly. These findings suggest that LSS deficiency affects the physiological function of the central nervous system, leading to impaired memory formation and learning ability.In conclusion, the present study provides evidencethat LSS plays a crucial role in learning and memory. The Morris water maze test is a useful tool for assessing the cognitive function of rodents and can help to unravel the molecular mechanisms underlying the learning and memory processes in the brain. Further research is needed to understand the precisemechanisms by which LSS affects neuronal function and synaptic plasticityFuture research can focus on exploring therelationship between LSS and other brain functions, such as emotion and behavior, and how it maycontribute to the development of neurological disorders. Additionally, investigating the potential therapeutic effects of manipulating LSS in preventing or treating cognitive impairments can provide insights into novel treatment options for neurological disorders.Furthermore, the study of LSS can be expanded beyond animal models to include human subjects. Non-invasive techniques such as transcranial magnetic stimulation can be used to manipulate LSS in the human brain, allowing for the investigation of its effects on cognitive function and potential clinical applications.In summary, the study of LSS is crucial in understanding the underlying mechanisms of learningand memory in the brain. Further research can provide valuable insights into the development of novel treatments for neurological disorders and the optimization of cognitive function in healthy individualsOne potential application of LSS research is the development of interventions for cognitive disorders such as Alzheimer's disease. Alzheimer's is characterized by a decline in memory function and is associated with changes in brain structure andactivity. Studies have shown that LSS can modulate neural activity in regions of the brain associatedwith memory and cognition, suggesting that it could be used to treat Alzheimer's by enhancing memory function.Another potential application of LSS research is the optimization of cognitive function in healthy individuals. For example, athletes and professionals who require high levels of cognitive performance could benefit from LSS interventions that enhance memory, attention, and other cognitive functions. Additionally, LSS could be used to improve cognitive performance in older adults, who often experience declines incognitive function as a result of aging.In conclusion, the study of LSS is an important areaof research with significant implications for our understanding of learning and memory in the brain. Continued research in this area could lead to the development of new interventions for cognitive disorders and the optimization of cognitive functionin healthy individuals. As the technology for LSSbecomes more precise and accessible, its potential for clinical and real-world applications will only continue to growIn summary, Long-term Synaptic Plasticity (LSS) plays a critical role in learning and memory processes in the brain. LSS changes can be influenced by age-related decline, environmental factors, and neurological disorders. Understanding the mechanisms and impact of LSS can aid in the development of effective treatments for cognitive disorders and improve cognitive function in healthy individuals. Further research and advancements in LSS technology can enhance its potential for clinical and real-world applications in the future。
脑器质性精神障碍 brain organic mental disorders脑器质性精神障碍(brain organic mental disorders)是指由于脑部感染、变性、血管病、外伤、肿瘤等病变引起的精神障碍,又称脑器质性精神病(brain organic psychosis)。
随着人类寿命的延长,老龄人口逐渐增加,脑器质性精神障碍的发病率也明显地增高。
脑器质性精神障碍的临床表现仍可概括为急性脑器质性综合征两种。
急性脑器质性综合征起病多急骤,病情发展较快,病程较短,损害范围较局限,预后多良好,其病变往往是可逆性的。
慢性脑器质性综合征则起病多缓慢。
病情发展较慢,有逐渐加重趋势,病程多持久,预后较差。
病变常不可逆。
不少脑器质性精神障碍既有器质性的临床特征,又伴有某些显而易见器质性障碍的表现,两者之间有相互交织、相互重叠现象。
本节将介绍几种常见脑部疾病伴发的精神障碍。
一、颅脑外伤所致精神障碍颅脑外伤性精神障碍是指颅脑受到外力的直接或间接作用,引起脑器质性或功能性障碍时出现的精神障碍。
平时与战时均属多见,青壮年居多。
[病因及发病机理]各种原因导致的闭合性与开放性颅脑损伤是发病主要因素,个体的素质特征及外伤后的心理社会因素有一定作用。
闭合性颅脑外伤所致精神障碍尤为常见,开放性颅脑损伤则与远期或慢性精神障碍的关系密切。
颅脑外伤越重,发生精神障碍的机会越大,持续的时间也越长。
意识障碍与间脑和脑干网状激活系统损害密切相关,额叶和颞叶损害易致人格改变和精神病样症状。
[临床表现](一)急性期精神障碍1.意识障碍:见于闭合性脑外伤,可能是由于脑组织在颅腔内的较大幅度的旋转性移动的结果。
脑震荡意识障碍程度较轻,可在伤后即发生,持续时间多在半小时以内。
脑挫伤患者意识障碍程度严惩持续时间可为数小时至数天不等,在清醒的过程中可发生定向不良,紧张、恐惧、兴奋不安、丰富的错觉与幻觉,称为外伤性谵妄。
如脑外伤时的初期昏迷清醒后,经过数小时到数日的中间清醒期,再次出现意识障碍时,应考虑硬脑膜下血肿。

中国学龄儿童脑智发育队列研究英文The Study of Brain Development in Chinese School-Aged ChildrenIntroductionBrain development plays a crucial role in the growth and learning abilities of children. Understanding the factors that influence brain development is essential for educators, parents, and policymakers. This article aims to explore the research conducted on the brain development of Chinese school-aged children.Factors Affecting Brain DevelopmentSeveral factors contribute to the brain development of school-aged children in China. Firstly, genetics plays a significant role in determining a child's cognitive abilities and potential. Research has shown that certain genes are associated with intelligence and cognitive functions. However, it is important to note that genetics is not the sole determinant of brain development, as environmental factors also play a crucial role.Secondly, the environment in which children grow up greatly influences their brain development. Factors such as nutrition, exposure to toxins, socioeconomic status, and early childhood experiences can have a profound impact on cognitive development. For example, malnutrition during early childhood can lead to stunted brain growth and cognitive impairments.Research on Brain Development in Chinese School-Aged ChildrenSeveral studies have been conducted to investigate the brain development of Chinese school-aged children. One notable study is theChina Education Panel Survey (CEPS), which aims to understand the educational outcomes and cognitive development of Chinese students. The CEPS collects data on various aspects, including family background, school environment, and academic performance.Another study conducted by researchers at Peking University focused on the impact of air pollution on the brain development of children. The study found that exposure to high levels of air pollution during early childhood was associated with reduced cognitive abilities and increased risk of neurodevelopmental disorders.Furthermore, a longitudinal study conducted by the Chinese Academy of Sciences examined the effects of early childhood experiences on brain development. The study followed a group of children from birth to adolescence and found that positive early experiences, such as nurturing caregiving and stimulating environments, were associated with better cognitive outcomes.Implications for Education and PolicyThe research on brain development in Chinese school-aged children has important implications for education and policy. Firstly, it highlights the need for early intervention programs that focus on providing a nurturing and stimulating environment for children. This includes ensuring access to quality early childhood education, promoting healthy nutrition, and reducing exposure to environmental toxins.Secondly, the findings emphasize the importance of addressing air pollution in China. Implementing stricter regulations on industrial emissionsand promoting clean energy sources can help reduce the negative impact of air pollution on children's brain development.Additionally, the research underscores the significance of addressing socioeconomic disparities in education. Providing equal opportunities for all children, regardless of their family background, can help mitigate the effects of socioeconomic factors on brain development.ConclusionIn conclusion, research on the brain development of Chinese school-aged children highlights the complex interplay between genetics and environmental factors. Understanding these factors is crucial for promoting optimal brain development and ensuring positive educational outcomes. By implementing evidence-based interventions and policies, we can support the healthy brain development of Chinese children and enhance their overall well-being.。
DEVELOPMENT REPORT - June 25, 2001: Brain Disorders
By Jill Moss
This is with the VOA Special English Development Report.
An international committee of doctors says that the number of cases of brain diseases in developing countries is rising.
The doctors were reporting the information for the United States National Academy of Sciences. They say that brain diseases affect at least two-hundred-fifty-million people in the developing world.
These diseases include strokes, epilepsy and mental sicknesses such as schizophrenia and depression. They also include abnormal development of the nervous system, which causes mental slowness and cerebral palsy.
Richard Johnson of Johns Hopkins University in Baltimore, Maryland, was one of the leaders of the committee. He says poor countries usually do not have the resources to deal with brain diseases. This is because most developing countries are already struggling with food problems, the spread of infectious diseases and child health issues.
Srinivasa Murthy also served on the committee. She works for the National Institute of Mental Health and Neurosciences in India. She criticized the lack of international interest in brain diseases. For example, Doctor Murthy says fifty percent of all countries have no policies about brain diseases. In addition, she says health care centers in forty percent of the world’s countries do not offer common drugs to treat brain diseases.
Doctor Murthy says there are two reasons for this. One is a lack of money. The other is a lack of human resources. For example, a recent study shows most developing countries do not have enough doctors who treat mental sicknesses. Another barrier to action against brain diseases is the unfair way in which the public acts toward victims. Many victims of brain diseases are treated poorly.
The committee says there are effective and low cost medical treatments for these diseases. Yet these treatments are not often provided in developing countries. The committee says more treatments should be offered to poor countries. It says health care systems in developing countries should provide mental health services for their people.
The committee says efforts should be made to increase public understanding of brain diseases. Finally, the committee says national research programs should be established to study brain diseases.
