目的探討背駝式原位肝移植術中採用體外門-體靜脈無泵轉流的臨床效果.方法4例行背駝式原位肝移植患者，腸系膜下靜脈屬支插管經體外硅膠管（充滿肝素鹽水）與頸內靜脈或鎖骨下靜脈插管相接，在阻斷門靜脈后開通腸系膜下靜脈插管，門靜脈血從體外無泵轉流管流入上腔靜脈，觀察轉流前後腸道瘀血、門靜脈壓、血壓、脈搏等變化情況.結果門靜脈阻斷后腸道明顯瘀血、腫脹，門靜脈壓力明顯升高，血壓、脈搏有不同程度的波動，無泵門靜脈轉流開放后，腸道瘀血、腫脹明顯好轉，門靜脈壓力逐漸恢復正常水平，血壓、脈搏恢復正常.結論背駝式原位肝移植術中體外門-體靜脈無泵流具有方便、經濟、實用等優點，具有良好的臨床效果In economics, the higher school logistics socialization is to put the higher school rear service into the socialist market economy system, socialize the service body, changing self - service into social service through further reform ; commercialize the service fruits, changing service without teward into one with reward ; market the service ways, changing the direct service into indirect one, to thoroughly changethe condition that higher school ran society under the planned economy, overwhelm the bottle neck of higher school development, and create conditions for our country ' s higher education to be better suited to our rapid development
摘要從經濟學的角度來分析，高校後勤社會化就是將高校後勤服務納人社會主義市場經濟體系，通過深化改革逐步實現服務主體社會化，變自我服務為社會服務；服務成果商品化，變無償服務為等價有償服務；服務方式市場化，變直接服務為間接服務，從根本上改變計劃經濟條件下形成的「高校辦社會」的狀況，克服高校發展的體制「瓶頸」 ，為高等教育更好地適應我國快速發展的社會經濟創造條件。No nationwide studies document the trend, but anecdotally, doctors and physical therapists say that as portable computers become cheaper, more powerful, smaller and lighter, and as wireless internet access becomes ubiquitous, thousands are suffering persistent back, shoulder, wrist and neck aches
沒有全國性的研究證實此趨勢，但非正式談話中，醫師和物理治療師表示，隨著移動式電腦越來越便宜、威力更強大、體積更小更輕，以及無線上網管道變得無所不在，數以千計的人飽受持續性背部、肩膀、手腕和頸部疼痛之苦。Abstract : biological invasions are a continuous feature of a non - equilibrium world, ever more so as a result of accidental and deliberate introductions by mankind. while many of these introductions are apparently harmless, others have significant consequences for organisms native to the invaded range, and entire communities may be affected. here we provide a survey of common models of range expansion, and outline the consequences these models have for patterns in genetic diversity and population structure. we describe how patterns of genetic diversity at a range of markers can be used to infer invasion routes, and to reveal the roles of selection and drift in shaping population genetic patterns that accompany range expansion. we summarise a growing range of population genetic techniques that allow large changes in population size ( bottlenecks and population expansions ) to be inferred over a range of timescales. finally, we illustrate some of the approaches described using data for a suite of invasions by oak gallwasps ( hymenoptera, cynipidae, cynipini ) in europe. we show that over timescales ranging from 500 10000 years, allele frequency data for polymorphic allozymes reveal ( a ) a consistent loss of genetic diversity along invasion routes, confirming the role of glacial refugia as centres of genetic diversity over these timescales, and ( b ) that populations in the invaded range are more subdivided genetically than those in the native range of each species. this spatial variation in population structure may be the result of variation in the patchiness of resources exploited by gallwasps, particularly host oak plants
文摘:生物入侵是不均衡世界的一個永恆話題，尤其是當人類有意或無意地引入物種后.很多引入顯然是無害的，但另外一些則有著嚴重的後果，會給入侵地的生物以至於整個生物群落造成影響.本文總結了分佈區擴張的常見模式，概述了它們對遺傳多樣性和種群結構式樣所造成的影響.描述了如何根據以一批遺傳標記所得到的遺傳多樣性式樣來推斷入侵途徑，來揭示伴隨擴張選擇和漂變在形成種群遺傳樣式中的作用.本文對日益增多的群體遺傳學方法進行了總結，這些技術可以用來在不同的時間尺度上推斷種群規模所發生的巨大變化（瓶頸效應及種群擴張） .最後，我們以歐洲櫟癭蜂（膜翅目，癭蜂科，癭蜂族）一系列入侵的數據為例對一些方法進行了說明.從500 10000年的時間尺度上，多態的等位酶位點上等位基因頻率的數據表明: 1 ）遺傳多樣性沿入侵路線呈不斷下降的趨勢，支持了冰河期避難所作為遺傳多樣性中心的作用; 2 ）入侵地區的種群與該物種原產地的種群相比，遺傳上的分化更為強烈.這種種群結構在空間上的變異可能是被櫟癭蜂開發的資源尤其是櫟樹寄主在斑塊上出現變異的反映Since the existed research has n ' t illuminated the failure form of post - embedded reinforcing steel bar bonding anchor and its mechanism, has n ' t systematic research on factors influencing the function of post - embedded reinforcing steel bar bonding anchor, and also failed to test on the long period validity of post - embedded reinforcing steel bar bonding anchor, it is very unfavorable for the spread and application of post - embedding technique. in the meantime, the fact that the present post - embedding anchoring material is of few kinds, high prices and still - to - be - improved performance has become the bottleneck of the post - embedding technique ' s development, which has restricted its further application and development. therefore, it is of great importance to develop a new type high - performance inorganic anchoring material with reasonable price and improved performance
由於已有研究對后植鋼筋粘結錨固的失效形式、破壞機理未作出明確回答，對后植鋼筋粘結錨固性能的影響因素未進行系統研究，對后植鋼筋粘結錨固的長期有效性未予以試驗證實，不利於植筋技術這種新型結構加固技術的推廣應用，同時現有植筋錨固材料存在品種少、價格高、性能需要進一步改進和提高等局限性，已成為植筋技術發展的瓶頸，制約了植筋技術的進一步應用和發展，因此開發價格合理、性能優良的新型高性能無機質類錨固材料就顯得尤為重要和迫切。Locking a shared resource for exclusive access is a scalability bottleneck - it prevents other threads from being able to access that resource, even if idle processors are available to schedule those threads
