"培土宁风法"探析

通过文献追溯发现，“培土宁风法”肇始于《内经》，发展于仲景及唐、宋，发微于金、元、明、清，王旭高则明确提出“培土宁风法”。本法之含义：一是通过健脾益气，实卫固表，达到抵御或祛除外邪；二是通过补益脾胃，益气滋阴，达到预防或消除内生风邪。     

马齿苋抗家兔主动脉泡沫细胞形成机制的探讨

目的　探讨马齿苋抗家兔主动脉泡沫细胞形成的作用机制 ,研究影响动脉粥样硬化 (AS)形成的有关因素。方法　动物分为 4组 ,A、B、C 3组建立动物高脂模型 ,B、C组分别喂饲马齿苋干粉 8或 12g/ (d·只 ) ,实验 11周末 ,采血测定血脂、丙二醛、血液粘度等指标并观察透射电镜下主动脉内膜病理改变。用多元逐步回归分析 ,筛选影响AS形成的主要因素。结果　B、C组与A组相比 ,血清总胆固醇 (TC)、甘油三脂 (TG)、丙二醛 (MDA)、全血低切表观粘度、血浆中切表观粘度水平明显下降 (P <0 0 1) ;高密度脂蛋白胆固醇 (HDL -C)明显上升 (P <0 0 1) ,C组TC、全血低切表观粘度数值较B组明显降低 (P <0 0 1)。多元方程显示α =0 0 5,0 0 1时对Y有显著影响的是TC(X1) ,血浆中切表观粘度 (X6 )。结论　马齿苋可明显阻止或降低血清TC、TG、MDA、全血低切及血浆中切表观粘度的升高 ,并升高HDL -C ,随着剂量的增加 ,马齿苋作用增强。电镜观察显示马齿苋能使主动脉内膜泡沫细胞数目减少 ,脂质沉积减轻 ,抑制AS斑块形成。多元分析表明 ,影响主动脉AS形成的主要因素是TC及血浆中切表观粘度 ,二者皆为正向影响 ,且TC影响最大。试验显示 ,马齿苋降低该两项因素的作用最为明显

Assessment of the Life Cycle of a Wind and Photovoltaic Power Plant in the Context of Sustainable Development of Energy Systems

The conversion of kinetic energy from wind and solar radiation into electricity during the operation of wind and photovoltaic power plants causes practically no emissions of chemical compounds that are harmful to the environment. However, the production of their materials and components, as well as their post-use management after the end of their operation, is highly consumptive of energy and materials. For this reason, this article aims to assess the life cycle of a wind and photovoltaic power plant in the context of the sustainable development of energy systems. The objects of the research were two actual technical facilities—a 2 MW wind power plant and a 2 MW photovoltaic power plant, both located in Poland. The analysis of their life cycle was carried out on the basis of the LCA (life-cycle assessment) method, using the ReCiPe 2016 calculation procedure. The impact of the examined renewable energy systems was assessed under 22 impact categories and 3 areas of influence (i.e., human health, ecosystems, and resources), and an analysis was conducted for the results obtained as part of three compartments (i.e., air, water, and soil). The life cycle of the wind power plant was distinguished by a higher total potential negative environmental impact compared to the life cycle of the photovoltaic power plant. The highest levels of potential harmful impacts on the environment in both life cycles were recorded for areas of influence associated with negative impacts on human health. Emissions to the atmosphere accounted for over 90% of all emissions in the lifetimes of both the wind and the photovoltaic power plants. On the basis of the obtained results, guidelines were proposed for pro-ecological changes in the life cycle of materials and elements of the considered technical facilities for renewable energy sources, aimed at better implementation of the main assumptions of contemporary sustainable development (especially in the field of environmental protection).

中菲两国及不同地区唇腭裂临床治疗的比较

目的:比较不同国家、地区唇腭裂治疗的现状,为基层医院规范开展唇腭裂治疗提供具有实用参考意义的理论依据。方法:分别对2007-02-2007-07,间菲律宾Davao市医疗中心(第一组)、中国兰州大学附属第一人民医院(第二组)和中国上海交通大学医学院唇腭裂治疗研究中心(第三组)住院手术的唇腭裂病例进行比较分析。第一组共200例,男133例,女67例;单侧唇裂150例,双侧唇裂48例,腭裂2例。年龄分布是:0～12个月53例,2～4岁85例,5～12岁52例,13～18岁4例,19～25岁4例,>26岁2例。第二组共160例,男85例,女75例;单侧唇裂54例,双侧唇裂7例,腭裂53例,唇裂二期17例,牙槽突裂植骨1例,腭瘘与复裂28例。年龄分布是:0～12个月10例,2～4岁56例,5～12岁58例,13～18岁23例,19～25岁8例,>26岁5例。第三组共300例,男175例,女125例;单侧唇裂36例,双侧唇裂16例,腭裂98例,唇裂二期36例,牙槽突裂植骨33例,面横裂、斜裂5例,腭瘘与复裂29例,咽成形术32例,腭心面12例,robin 3例。年龄分布:0～12个月72例,2～4岁90例,5～12岁52例,13～18岁43例,19～25岁42例,>26岁1例。结果:第一组以唇裂为主,且手术年龄普遍过大,唇裂术式以Millard为主,口轮匝肌的对位吻合为主流术式,但该组病例单一。第三组的手术年龄小于前2组,病种明显丰富于前2组。前2组唇裂术后上唇组织明显过紧。结论:唇腭裂是颌面部最常见的先天性畸形,也是目前全球各类慈善组织或基金会热衷服务的项目之一。开展的内容与所在医院的设施有密切的关系,手术的病种除与医院设施相关外,参与术者的操作技能起着不可忽视的作用,如何做好术后随访是该类手术有待加强的工作之一。     

宋业强治疗慢性荨麻疹用药经验

宋业强教授认为慢性荨麻疹患者多因正气虚弱或先天不足,加之外感风邪兼夹寒、热、湿邪致病,其证型不仅包含虚证,也有实证,更多以虚实夹杂为主,因而病程长、易反复.宋教授根据临床经验将本病分为表虚风寒证、表虚风热证、血热风盛证、湿热夹风证,分别应用玉屏风散合桂枝汤、固表清热祛风汤、复方白鲜皮汤、龙胆泻肝汤加减治疗.并重视中西医...
