创新和谐教育的认识与实践

构建和谐社会,重要的是必须构建好和谐社会的上层建筑,这其中就离不开教育。教育在构建和谐社会中,在解决关系人民群众切身利益的现实问题,促进经济社会的协调发展,解决社会公平问题,加强法制建设,保障社会安定团结,建立学习型社会方面发挥着基础的、重要的、不可或缺的作用。由此,充分认识教育在构建和谐社会中的重要作用,树立和谐教育理念,着力构建和谐教育具有十分重要的意义。一、和谐教育已有的实践与认识和谐教育及其思想并非由当今“和谐社会”的提出而产生,而是古今中外教育家经过相当漫长的实践研究过程提出的,至今还在不断充实丰…     

Cerebrospinal fluid and plasma propofol concentration during total intravenous anaesthesia of patients undergoing elective intracranial tumor removal

INTRODUCTION The specific morphologic properties of choroidal epithelium and the existence of a cerebrospinal fluid(CSF)pathway for drug distribution to the central nervous system(CNS)suggest that the choroid plexus-CSF route may be more significant than pre-viously thought for drug delivery to the brain(Ghersi-Egea and Strazielle,2001).There is limitedl d l d-n d information about the CSF pharmacokinetics of propofol in humans(Engdahl et al.,1998;Dawid-owicz et al.,2001a).Propofol…     

Effects of different types of palatal lateral excisions on growth and development of maxilla and dental arch

Obiective:This study aimed to explore the effects of different types of palatal lateral excisions on the growth and deveiopment of the maxilla and dental arch.and to investigate the underlying mechanisms.Methods:A total of 1123-week-old Sprague-Dawley(SD)male rats were randomly divided into a control and 3 experimental groups:the mucoperiosteal denudation group,the mucosal flap excision group,and the periosteum excision group.In the experimental groups,bilateral mucoperiosteal,mucosal flap and periosteum were excised respectively in the lateral one half of the palate.Four rats in each group were randomly chosen for sacrifice every two weeks.The maxilla was dissected following the excision.The widths of the maxilla and dental arch were measured and the histological phenomena were investigated at different phases.At the same time.12 animals in each group were sequentially injected with calcein every two weeks.Three animals in each group,whose fluorescent labeling was used,were sacrificed for investigating bone formation at Week 8 following injection.Results:(1)Each experimental group presented the constriction of the maxilla and dental arch.The upper first molars in the experimental groups inclined medially.The mucoperiosteal denudation group showed the largest degree of effect followed by the periosteum excision group.The indices of the mucosal flap excision group,which retained the structures of the periosteum layer,had the most approximate values to the control group;(2)Different histological changes among the experimental groups were detected.The fibers penetrated into the palatal bone asSharpey's fibers in the mucoperiosteal denudation group.The pattern of bone deposition was the bundle type.Sharpey's fiberswerenotfoundinthemucosaI flapandperiosteum excisiongroups andthedepositions ofpalatalbonewerethelamellartypeasthose in the control group;(3)The rates ofbone deposition in the experimental groups decreased compared with the control group.The rates in different phases were the most approximate values to those of the control group in the mucosal flap excision group,which has the same structure of periosteum as the control group.Conclusion:There were different effects on the growth and development of the maxilla and dental arch in different typos of palatal lateral excisions.Periosteum is important for bone formation and deposition pattem.The prevention of Sharpey's fibers forming and attaching to the palatine can effectively avert the following malformation.     

大学生运动员反应时跟踪实验及评定方法研究

采用EP202/204选择、声光反应时测定仪对武汉市5所高等院校的大学生运动员的反应时进行跟踪测试实验,结果显示:运动员反应时的个体差异较大,差异主要取决于遗传因素,训练虽可提高,幅度较小;不同运动员的反应时在一定范围内变化,变化的数据与本人机能状况相关,机能好时,反应时快,反之,反应时延长,变化范围在本人平均反应时的上下95-105%波动.提出了评定大学生运动员反应时的方法与标准.     

Suggestions for Conducting a Reading Comprehension Lesson

I. Aims and Content of a Reading Comprehension Lesson As stated in the New English Course curriculum, "the aim of senior school English teaching is to develop students' overall abilities of listening, speaking, reading and writing, with more emphasis on reading". The main task of a reading comprehension lesson is to develop students' reading ability and help them form good habit of reading. Enabling students
