应用乳导管内窥镜诊治乳头溢液患者70例临床观察

目的:探讨应用乳导管内窥镜诊治乳头溢液患者70例的临床效果。方法:以笔者所在医院2011年6月-2015年6月收集的70例乳头溢液患者资料为例,所有患者均行乳导管内窥镜、溢液涂片检查。回顾性分析患者的诊疗结果,并就两组方法展开分析。结果:70例患者经乳导管内窥镜发现占位性病变22例,其中7例为乳腺癌、15例为乳管内乳头状瘤。单发病变56例,多发病变14例。与溢液涂片检查结果比较,差异无统计学意义(P>0.05)。乳管炎患者乳导管内窥镜下显示管腔扩张不明显,管腔内存在絮状物或浑浊的分泌物;乳管扩张患者可见明显的扩张,存在少量的絮状物,管壁光滑可见毛细血管;乳管内乳头状瘤患者可见管腔内存在黄色或红色的肿物;乳管内癌患者可见管腔内肿物;乳头皮质囊肿患者插入内窥镜困难,未见乳管结构。经乳导管内窥镜诊疗的33例患者,随访3个月,乳管扩张和乳管炎情况完全消失,不再出现溢液情况。37例行手术的患者,4例溢液情况完全消失,2例仍有少量暗红色血性溢液,内窥镜复查显示乳管内隆起病变,再次给予冲洗治疗后,溢液明显减少。结论:针对乳头溢液患者可行乳导管内窥镜诊治,准确率较高,能为后期的诊断和治疗提供科学依据

Big Data Meets the Needs of Disaster Information Management

1灾难信息管理灾难管理旨在有效地应对和避免自然灾害(如飓风、地震、海啸、火灾)及人为灾害(如战争、恐怖袭击)等紧急事件给社会和民众带来的财产损失和生命威胁[1]。近年来,随着自然灾害的不断发生、人为破坏和恐怖主义的蔓延,灾难管理和灾难恢复受到了越来越多的关注。如何能够快速准确地预测灾难发生的方式和类型,评估灾难的破坏程度和影

探讨管理会计在我国的应用问题

由厦门大学会计发展研究中心提供的第五届会计与财务问题国际研讨会——当代管理会计新发展论文集中的第四部分：管理会计创新及相关模式21本文认为，管理会计从西方引入我国虽已有20余年，但回顾其应用与发展却不甚理想。文章拟从管理会计在我国在企业中应用的现状入手，剖析影响我国管理会计运行原因，并提出相应的对策

国开行可赎回债券和可回售债券的定价探讨

摘要：可赎回债券可以分解成普通债券和债券看涨期权的组合，可回售债券可以分解成普通债券和债券看跌期权的组合。本文使用BDT模型对国家开发银行自2001年以来发行的可赎回债券和可回售债券定价，结果发现可赎回债券被高估，而可回售债券被低估。 Abstract：Callable bonds can be decomposed into bond and bond’s call option, while puttable bonds can be decomposed into bond and bond’s put option. We use BDT model to price the callable and puttable bonds issued by China Development Bank since 2001. It is found out that callable bonds are overvalued, while puttable bonds are undervalued

Research progress in PAHs degradation genes and enzymes

通讯作者E-mai:l [email protected][中文文摘]由于环境中的多环芳烃(PAHs)具有高遗传毒性和“三致”性(致癌、致畸和致突变),其生物降解基因和降解功能酶研究备受关注。多环芳烃双加氧酶是近年来研究较多的多环芳烃降解的关键酶系之一,主要由细菌产生,可通过氧化反应使多环芳烃开环生成小分子的中间产物并最终氧化成CO2和水。目前,有关这类酶的理化性质、结构特点、功能等的研究相继开展,本文对PAHs降解基因、降解酶的研究现状与发展趋势进行综述。[英文文摘] Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants that accumulated in the environment due to a variety of anthropogenic activities. More and more attention has been paid to PAHs, because of their toxic, carcinogenic and mutagenic potential. The aromatic ring-cleaving enzymes produced by microbes play a definitive role in the metabolism of aromatic compounds. These enzymes can catalyze the addition of two atoms of molecular oxygen directly onto aromatic rings and their derivatives, with subsequent cleavage of aromatic rings. At present, the studies on the physical and chemical properties, molecular structure, and functions of these enzymes are carried on, and this paper reviewed the current status and trend on the research of the genes and enzymes involved in PAHs degradation.国家自然科学基金项目(40576054,40476047);长江学者和创新团队发展计划资助项目(40521003

Some biometeorological features of wheat field in the ecological conditions of oasis at the Heihe Region

观测分析了 HEIFE地区绿洲中麦田的一些微气候特征 ,结果表明 SPAC中水势随高度呈显著梯度分布 ,在土壤 -植物以及植物 -大气界面 ,水势值存在两个大的跳跃 ;水势廓线存在明显的日变化 ;SPAC各部分水势变化的起伏顺序是大气 >植物 >土壤 ,说明水势变化受植物水分代谢进程直至气象因子的强烈影响和控制。冠层上方近地面风温湿的时空剖面显示出白天与夜晚相比 ,大气混合得较好 ;日出前则大气较为稳定 ;在典型晴天条件下 ,麦田上方的大气存在内边界。其结构受来自沙漠干热风的影响和控制。冠层内部也存在着温度、湿度、CO2 浓度、PAR、蒸腾作用、光合作用、气孔导度和叶温的垂直梯度 ,其廓线的日变化主要受太阳辐射的强烈控制 ,同时也受冠层内部不同层面叶片水分代谢强弱以及土壤状况的影响 ,其温湿廓线表现出与冠层上方不同的变化模式。 【英文摘要】 We observed and analysed some characteristics of biometeorology over and within canopy in spring wheat field in the ecological conditions of oasis during HEIFE program.Water potential in SPAC appeared a well vertical profile and the profile showed an obvious diurnal variation.There were water potential jumps in the SPAC junction boundaries.Sequence of variation intensity for water potential in each part of the SPAC was atmosphere,plant and soil.It is shown that the water potential was influenced and control...中国科学院资助;; 国家自然科学基金!( No.94 870 0 4 );; 日本文部省资助!( No.0 2 0 4 1 0 4 3

Some characteristics of energy exchange at the underlying surface of desert and oasis in Hexi Corridor

在河西走廊黑河地区沙漠和绿洲下垫面生态条件下,用涡旋相关法研究了能量输送的不同模式和日变化进程;以及两种生态条件下能量输送间可能存在的相互关系。在沙漠生态条件下,大部分净辐射用于显热散失,另一部分用于向地下传输,较少部分则用于潜热输送,其方向在白天向下,在夜间向上;其Bowen比为13.16。在绿洲的麦田生态条件下,能量输送的基本模式为:大部分净辐射用于潜热散失,其输送方向与沙漠相反,另一部分用于显热散失,其输送方向一般在午后约3h即由上传转为下传。土壤热通量在最大时一般不超过40W/m2。冠层光合作用固定的能量则更小,其数量级维持在10W/m2以下,小麦不同生长阶段各能量分量占净辐射的比例有所变化。麦田的Bowen比从分蘖期的0.33降到拔节期末的0.095。当有干热大风自沙漠吹向绿洲时观测了典型的绿洲效应,其能量输送模式发生很大变化,显热显著下传,地热流量减弱,潜热散失强烈,起风后约2h潜热甚至高于净辐射。表明沙漠的能量组分参与了麦田的能量平衡过程。 【英文摘要】 With eddy correlation,we studied the pattern and dinurnal variation course of energy transfer for the underlying surface of desert and wheat field in oasis and their possible relationship between two ecological conditions at Heihe River region in Hexi Corridor during the HEIFE project.In the desert,the most net radiation( Rn )was consumed by sensible heat( H )transfer,another part of Rn conducted into desert surface,and a small part of Rn was dissipated by latent heat( LE ) transfer on a fine ...中国科学院资助项目;;国家自然科学基金;;日本文部省资助项
