绽放华丽的青春

近代著名的学者梁启超先生说过：“少年智则过智．少年富则国富．少年强则国强，少年独立则国独立．少年自由则国自由，少年进步则国进步．少年胜于欧洲则国胜于欧洲，少年雄于地球则国雄于地球。”     

我和祖国一起成长

正祖国是哺育我们的母亲,是生命的摇篮,我们应该为自己是一个中国人而骄傲。因此,我时常对自己说:"我是中国人,我为此而骄傲!"我坚信只有心系祖国,才会健康成长!我哑哑学语的第一个发音是"妈妈",我首先认的词是"中华",我会唱的第一首歌是《我爱北京天安门》……从那时起,稚嫩的心啊,就一直向着祖国妈妈。人生道路上15个春夏秋冬,我很幸运,时时充满欢乐,处处铺满鲜花。中华的历史告     

宫内缺氧及当归注射液干预对幼年大鼠海马齿状回神经元与学习记忆能力的影响

BACKGROUND： The present study analyzed the effect of 3 days （2 h/d） intrauterine hypoxia on learning and memory in juvenile rats, as well as the therapeutic effects of Angelica sinensis on dentate gyrus neurons, as well as learning and memory. OBJECTIVE： To explore the effects of intrauterine hypoxia on hippocampal dentate gyrus neurons, as well as learning and memory, in juvenile rats; to explore N-methyI-D-aspartate receptor-1 （NMDAR1） expression in the dentate gyrus of neonatal rats following intrauterine hypoxia, as well as prolonged hypoxia; to investigate the regulatory mechanisms of Angelica sinensis. DESIGN, TIME AND SETTING： A randomized and controlled experiment based on developmental neurobiology was performed at the Department of Histology and Embryology in Luzhou Medical College from October 2007 to October 2008. MATERIALS： Angelica sinensis solution （250 g/L） was obtained from Central South Hospital of Wuhan University, China. Neuron-specific enolase and NMDAR1 mRNA in situ hybridization reagents were provided by Wuhan Boster Biological Technology, China. Image-Pro Plus 6.0 analysis system was purchased from Media Cybernetics, USA. METHODS： Healthy pregnant Sprague Dawley rats （n = 30） were randomly divided into control （n = 10）, hypoxia （n = 10）, and Angelica （n = 10） groups. The Angelica and hypoxia pregnant rats were placed in a three-gas incubator （oxygen concentration： 13%） starting with day 14 of pregnancy for 2 hours/day for 5 consecutive days to establish a fetal rat intrauterine hypoxia model. One hour prior to modeling, the pregnant rats from the Angelica and hypoxia groups received Angelica sinensis and normal saline （8 mL/kg） injections, respectively, through the caudal vein. The control group procedures were identical to the hypoxia group, but lacked the hypoxic conditions. MAIN OUTCOME MEASURES： Brain tissues of neonatal rats were used to detect expression of NMDAR1 mRNA, and brain tissues of juvenile rats aged 30 days were used to determine neuron-specific enolase mRNA expression by in situ hybridization. Microscopic images （400x） of the hippocampal dentate gyrus were collected. The integral optical density （IOD） value of positive NMDAR1 mRNA cells in the dentate gyrus of neonatal rats, as well as the quantity and the IOD value of positive neuron-specific enolase mRNA cells in the dentate gyrus of juvenile rats, were analyzed with Image-Pro IPP6.0 software. At 30 days after birth, learning and memory parameters were measured in the juvenile rats using Morris water maze. RESULTS： The quantity and the IOD value of positive neuron-specific enolase mRNA cells in the dentate gyrus of the hypoxia group juvenile rats were significantly less than the control group （P 〈 0.05）, and also less than the Angelica group （P 〈 0.05）. The IOD value of positive NMDAR1 mRNA cells in the dentate gyrus of the hypoxia group neonatal rats was significantly greater than the control group, and also greater than the Angelica group （P 〈 0.05）. In the Morris water maze, the searching time during the probe trial and reversal probe trial was shorter in the hypoxia group juvenile rats compared with the control group, and the Angelica group was prolonged compared with the hypoxia group （P 〈 0.05）. CONCLUSION： Intrauterine hypoxia increased expression of NMDAR1 mRNA in the dentate gyrus of neonatal rats, reduced the number of dentate gyrus neurons, and negatively affected learning and memory in juvenile rats. In contrast, Angelica sinensis injection improved the intrauterine hypoxic condition, increased the number of dentate gyrus neurons, and improved the learning and memory deficits of the juvenile rats.

笑着向烟草告别(五)

正学英雄孩子处于可塑性最强的时期。这个时期的孩子,入于苍则苍,入于黄则黄,就看你给他们什么影响。早先,我们说文学是生活的教科书,现在纸质的文学书籍早已赶不上影视的传播面和影响力。当年歌德的《少年维特之烦恼》一出,维特的穿着打扮甚至他的自杀,都成为青少年中的一时风气。现在,影视作品中人物的服装、发型、口头语,乃至举手投足也都会吸引青少年模仿学习,尤其是作品     

德国Galli心理剧治疗对少年精神障碍患者社会适应能力及疗效的干预研究

目的探讨德国Galli心理剧治疗对少年精神障碍患者的社会适应能力及疗效的干预效果。方法 60例少年精神障碍患者按入组先后顺序分为研究组和对照组,各30例,用社会适应能力诊断量表、临床大体印象量表(CGI)分别在治疗前1天、治疗4周后的次日进行评定,比较两组评分变化。结果社会适应能力诊断量表的评分,两组治疗前后差值无显著性差异(P0.05),临床大体印象量表的评分,两组治疗前后差值有显著性差异(P0.05)。结论德国Galli心理剧治疗可提高少年精神疾病患者的疗效,但对社会适应能力的改变无明显效果。
