886例人心传导系统形态变异研究

探讨划分心传导系统 (CCS)变异与发育异常的界限。用本组建立的CCS检查法[1] ,连续切片 ,HE或Masson三色染色 ,光镜检查 ,对非心源性死亡组 (737例 )和心源性猝死组 (14 9例 )进行形态学及死因对比分析。结果显示 :(1)人CCS具有大小、位置和形态的先天性变异 ;(2 ) 4例心源性猝死者的房室结、房室束发育异常。房室束分叉部向室间隔膜部内移位、偏向于室间隔左侧、向左下侧移位 ,以及不足 1/2房室结移位至中心纤维体内、普通心肌移位至房室束或左束支内等应属变异 ;成年人胎儿型房室结及房室结全部移位至中心纤维体内或房室束完全分成 3束以上 ,房室束分叉部移位至三尖瓣根部应视为发育异常     

The Natural Law Foundation of the Market

In answering three important questions related to natural law, this paper offers a coherent explanation of the market. We argue that the market, rather than a mechanism that simply serves narrow self-interests, finds its legitimacy in the ethical origins of the market order. The need for law to support and sustain the market, including by imposing necessary limits on the freedom of the market players, flows from those ethical origins.     

Goodwill Currency,Changing Faces

Capturing many styles of oxen in gold, bronze,or dressed in colorful lights, is a delight to my camera eyes. In this, the Year of the Ox in the Chinese calendar, I am excited about prospects of a more adven-     

Mahjong and Baseball

My television screen flicked on, and the crowd's excitement with sports action seemed so familiar, yet momentarily strange. An announcer's voice described the game with infectious enthusiasm. The crowd of over 70,000 in the stands was going wild, and the players were moving with precision and speed. The pitching, the batting, runners racing around the bases, and acrobatic fielding. Yes, this was baseball, a     

Super Surprises,Unusual Places

i was staggering and tripping my way up and down the steep stairs of the Great Wall, repeating to myself the same words former U.S. President Richard Nixon had exclaimed on his historic visit to Beijing: The Great Wall is truly Great!     

水牛肝片吸虫病间接ELISA诊断方法的建立及应用

以肝片吸虫的分泌-排泄物作为抗原(ES抗原),建立水牛肝片吸虫病间接ELISA诊断方法,并用此方法与粪便检查法检测江苏和安徽2省10县(市)302户的307头水牛的血清和粪便;间接ELISA诊断法的最佳工作条件,每孔包被0.2 μg抗原,血清稀释度为1960,二抗稀释度为1600.结果粪便检查出虫卵的阳性水牛43头,阳性率为14.01%,其中安徽省为11.61%(18/155),江苏省为16.45%(25/152);用间接ELISA法检测299头水牛血清,阳性87头,阳性率为29.19%,其中安徽省为23.53%,江苏省为34.92%,两种方法的符合率为86.05%.     

旋毛虫新生幼虫cDNA文库的构建

为了克隆和研究旋毛虫新生幼虫功能性抗原基因,采用酸性异硫氰酸胍-酚-氯仿一步法提取新生幼虫总RNA,Oligo(dT)纤维素柱纯化mRNA,反转录合成第一链cDNA及第二链cDNA,用CHROMA SPIN-400柱离心层析纯化后,与载体λZAP Express连接.体外包装后得到中国猪旋毛虫(Trichinella spiralis)分离株新生幼虫cDNA文库.文库容量为2.0×106,重组率为98.6%,插入片段长度在0.4×103-2.0×103bp.     

18世纪的财产与刑罚:贝卡里亚及其批判者

贝卡里亚否认将财产视为自然或绝对的权利,但未正式提倡废除一切私有权。他指出个体欲望能促使每个人积极奋斗,并使财富在此过程中得以扩张,因此认为资源不平等在某种程度上是能够接受的。这种观点与《犯罪与刑罚》的主旨存在着潜在冲突：更为平等的财富和权力对他提倡的刑事司法制度形成至关重要。他的观点受到当时比他保守和激进的人的质疑和批评。保守主义者费尔迪南多·法基内认为等级社会中土地所有者的家族式统治应当得到刑法的维护和支撑。早期社会主义者艾伯·马布利则对贝卡里亚倡导的改革在充满竞争和不平等的资本主义社会的可行性表示怀疑。     

马克思主义民族观教育的时代价值

在人类历史长河中,每个特定的时代,都有代表这个时代的特定的理论体系,这个理论体系与同时代的其他理论体系相比较,能够更敏锐、更准确、更深刻地从理论上表达当时社会发展的要求,它是时代精神的集中体现,是时代的旗帜。
