BMI、WHR与膝关节慢性创伤发病风险的关系研究

研究对象为哈尔滨市第六医院康复科402例膝关节慢性创伤患者（2005年～2010年）,数据采集内容包括：年龄、性别、膝关节慢性创伤、体质指数、腰臀比。根据性别不同对数据进行数理统计分析,通过体质指数（BMI）和腰臀比（WHR）标准对患者的肥胖程度进行分析。根据数据结果显示男子通过腰臀比定义为肥胖的往往高于女士。腰臀比在评价受试者肥胖的比例明显高于BMI测定结果（P〈0．05）,尤以男性突出。在膝关节慢性创伤患者中,腰臀比（WHR）与男性、女性膝关节骨关节慢性创伤的患病率存在显著性相关,男性患者达到了非常显著行相关,而体质指数（BMI）没有达到显著性相关。     

高校学籍管理工作之我见

高校学籍管理是指高等院校对学生从入学到毕业整个培养教育过程的管理,它在高校的整个教学管理中占有极其重要的地位。只有加强高校学籍管理工作,才能完成培养高质量人才的任务。     

高校学报的功能定位

高校学报是传播最新明成果和最新学术研究动态的重要园地。它不仅对最新学术思想，理论成果和化知识具有传播作用，而且在促进社会生产力的发展，引导正确的社会舆论，培养学术人才等方面有着十分重要的作用。因此，正确认识和定位高校学报的各种社会功能，有利于办好学报，促进学术事业的繁荣和发展。

高校思想政治理论课的环境、对象已经发生了许多新的变化，建设社会主义和谐社会的形势也对我们堡皆：雾高的要求。要认识高校思想政治理论课创新的现实紧迫性；要立足教学内容的创新，增强高校思想政治理论课教学的实效性；要从教学模式和方法上创新，增强思想政治理论课教学的吸引力。     

英、德职业教育体系差异的政策分析及启示

英国职业教育体系的结构化水平远不如德国,导致这一差异的重要原因在于长期以来两国的政策取向不同。其经验表明“市场化”并非职业教育发展政策的明智选择。在我国职业教育发展正面临错综复杂的诸多问题的关键期,政府应当从战略高度承担起其主要责任。

Effect of temperature on batch elastase production by Bacillus sp. EL31410

The production of elastase by Bacillus sp. EL31410 at various temperatures was investigated. In order to study the effect of temperature on elastase fermentation, different cultivation temperatures, ranging from 39 ℃ to 28 ℃, were evaluated in shake flask. The result indicated that 37 ℃ was best for cell growth at earlier stage; while maximum elastase activity was obtained when the cells were cultivated at 30 ℃. This result was verified by batch fermentation in 5-L bio-reactor under 37 ℃ and 30 ℃ temperature, respectively. The specific cell growth rate at 37 ℃ was higher than that at 30 ℃ during earlier stage of cultivation. The maximum value [5.5 U/(h-g DCW)] of elastase formation rate occurred at 24 h at 30 ℃ compared to 4.6 U/(h-g DCW) at 30 h at 37 ℃. Based on these results, two-stage temperature shift strategy and oscillatory temperature cultivation mode were evaluated in the next study. When compared to single temperature of 37 ℃ or 30 ℃, both two-stage temperature shift strategy and os     

教师权利的法律解读

教师的权利是法定的,它包括社会生活权利和职业权利两方面。我国法律对教师权利的确认和保护是全面的。但现实生活中我国教师尤其是处在基础教育第一线的教师却长期处在权利缺失的困境中。教师维权意识不强,维权现状不容乐观。因此教师应了解维权的途径,多渠道地去寻找法律救济。

Optimization of conditions for supercritical fluid extraction of flavonoids from hops (Humulus lupulus L.)

Waste hops are good sources of flavonoids. Extraction of flavonoids from waste hops (SC-CO₂ extracted hops) using supercritical fluids technology was investigated. Various temperatures, pressures and concentrations of ethanol (modifier) and the ratio (w/w) of solvent to material were tested in this study. The results of single factor and orthogonal experiments showed that at 50°C, 25 MPa, the ratio of solvent to material (50%), ethanol concentration (80%) resulted in maximum extraction yield flavonoids (7.8 mg/g). HPLC-MS analysis of the extracts indicated that flavonoids obtained were xanthohumol, the principal prenylflavonoid in hops.
