灾疫文化是人类应对灾害和疫病而创造出来的自救文化,它伴随人类始终,构成人类文明的持续不衰的动力.当代地球失律和气候失律,导致灾疫失律,即灾疫的日益全球化、日常生活化和治理的日常政务化趋势,迫使灾疫文化研究必然兴起,并以重建生境和生境主义文明为根本目标.围绕此一目标要求,灾疫文化研究必须探讨当代灾疫失律的自然机理和人力机制,揭示"自然、生命、人、社会"共在互存、共生互生的生态逻辑和限度生存的世界原理,探索生境主义道路,构建生境主义价值体系,以为在全社会范围内展开生境主义的灾疫启蒙教育提供认知、思想、智慧和方法资源.

目的:探讨重组人生长激素治疗特发性矮小症的临床疗效及安全性.方法:选取2010年6月至2012年12月我院儿科诊治的特发性矮小症患儿70例,采用随机数表法将患儿分成两组各35例,对照组给予营养支持,并补充定量钙及赖氨基醇维生素B12,治疗组在对照组治疗的基础上于每晚临睡前1 h给予皮下注射重组人生长激素0.15 U/(kg·d),连续治疗6~18个月,比较两组患儿治疗前后的生长速度(GV)、骨龄(BA)、骨龄对应的身高标准差分值(HtSDSBA)、年龄对应的身高标准差分值(HtSDSCA)、骨龄/实际年龄(BA/CA)、预测成年身高(PAH)变化,并观察不良反应.结果:两组患儿治疗前各项指标比较差异无统计学意义(P>0.05),治疗后6个月、12个月、18个月治疗组GV、HtSDSBA、HtSDSCA、PAH与对照组比较差异有统计学意义(P<0.05);两组治疗后6个月、12个月、18个月BA、BA/CA比较差异无统计学意义(P>0.05);治疗组在治疗期间出现注射部位皮肤红肿1例,为一过性,停药后自行消失,肝肾功能、血常规、尿常规、血糖、甲状腺功能未见异常.结论:重组人生长激素治疗特发性矮小症安全、有效,可有效增加患儿生长速度,对骨龄的增长不明显,值得在临床上推广使用.

Models of optimal escape strategy predict that animals should move away when the costs of fleeing (metabolic and opportunity costs) are outweighed by the costs of remaining. These theoretical models predict that more vulnerable individuals should be more reactive, moving away when an approaching threat is further away. We tested whether escape behaviour (includ- ing 'escape calling') ofLithobates sphenocephalus approached by a human was influenced by body size or the initial microhabi- tat that the individual was found in. Irrespective of their size, frogs in the open tended to remain immobile, enhancing their cryp- sis. Frogs in cover showed different responses according to their body size, but, contrary to our initial predictions, larger frogs showed greater responsiveness (longer flight initiation distance and distances fled) than small frogs. Small frogs tended to remain closer to water and escaped into water, while larger individuals were more likely to jump to terrestrial cover and call during escape. Density of frogs near the focal animal had no effect on escape behaviour. This study indicates a range of escape responses in this species and points to the importance of divergent escape choices for organisms which live on the edge of different environments .

一个作家是靠作品立世的,他的生命力的长短在某种意义上也就取决于他的作品的存世价值.当我们再次讨论史铁生作品中的生死问题时,他已经死了.可他的作品还活着,并且在可以预见的很长时间内他会以一种精神站立的方式存在,人们的阅读会让他一次次地复活,他把自己对人生的理解、生

时间在路上发动引擎,逃离城市的束缚,打开音乐,带着灵魂去旅行.来自生活的压力让都市人寻找着各自解压的方法.散发着无限魅力的自驾旅行,博得了大多数都市客的青睐.台湾音乐人高明骏算是一个在艺人圈和自驾圈里都晌当当的人物,他在去年底发行了一首单曲-《时间在路上》,记录了他的人生历程,也唱出了他的旅行感悟.
