上皮生长因子预防心脏术后心包粘连的实验及临床研究

目的探讨上皮生长因子(EGF)对心脏术后心包粘连的预防作用.方法术中对犬心包内喷洒上皮生长因子3个月后,观察心包粘连情况;选先天性心脏病、房缺及室缺病人40例,术中心包内喷洒上皮生长因子,术后6个月、12个月经CT检查,判定心包粘连、增厚结果.结果在动物实验和临床研究中,实验组粘连程度显著低于对照组(P<0.01).结论 EGF心包内应用有明显预防心脏术后心包粘连的作用.

温公颐中国逻辑史研究方法论初探

温公颐先生中国逻辑史研究的方法论涉及一般原则和具体方法两个层面。其中,一般原则主要包括"贵有创见"、实事求是和发展的观点3个方面。具体方法主要有比较的方法、语言学的方法以及逻辑与历史统一的方法等。温公颐中国逻辑史研究的方法论,在一定意义上是对近代以来中国逻辑史研究中简单比附这一思路与方法的有力矫正。     

非对称度量空间上不动点定理

提出建立在非对称度量空间之间的上收缩映射和下收缩映射的概念.考虑到非对称度量的不对称性,进一步定义了非对称度量空间到自身映射的左不动点和右不动点.最后,给出了非对称度量空间上的两个不动点定理.     

Functional magnetic resonance imaging of amphetamine craving

The aim of this study is to identify the brain activity associated with amphetamine craving for understanding the neurobiology of addiction by watching pictures of happy, sad or amphetamine. Brain activity was measured in 12 amphetamine addicts and 12 healthy subjects by fMRI while the subjects watched pictures designed to elicit happy feelings, sad feelings, or the desire to use amphetamine. The result demonstrated that amphetamine cues led to abnormally high cingulate and low frontal lobe activation in amphetamine addicts, who showed abnormalities in affect-related brain activation.     

多维测量结果不确定度评价方法初探

为解决以多维矢量形式存在被测对象的测量质量评定问题,该文应用测量不确定度理论和多元概率统计方法,将测量不确定度理论进行了向多维的拓展;对多维情况下的测量不确定度传播律进行了推导;论述了多维不确定度的表示方法及空间几何意义;提出了以多维不确定度比较不同测量结果质量的方法;并给出了常用多维测量方法,如等精度独立多维测量和不等精度独立多维测量的不确定度评定方法。理论分析及仿真算例表明,所提出的理论具有较完备的体系,能够满足测量实际中常用多维测量方法的不确定度评定需求。     

The Response of Debris-Flow Events to Solar Proton Flares （Ⅰ）

By analyzing the observation data from Dongchuan Debris Flow Observation and Research Station and historical data from year 1965 to 1990 gotten from National Astronomical Ob-servatories/Yunnan Observatory,the responding of debris flow in Jiangjia Ravine to Solar Proton Flare is studied. The following conclusion can be drawn. Solar Proton Flare,as one of most im-portant astronomical factors,affects the activity of debris flow in Yunnan. Generally,from 1965 to1990,the more active Solar Pro-ton Flare is,the greater the probability of high frequency and large runoff of debris flow is. On the contrary,the less active Solar Pro-ton Flare is,the greater the probability of low frequency,small runoff,and low sediment transport of debris flow is.     

Development of Full Automatic External Welding Machine for Annular Welds of Pipeline

To meet the demands of rapid development of pipeline constructions in China, a complete set of full automatic external welding machine for annular welds of pipeline and welding procedure have been developed thereof. The system has been applied in the “West-East Pipeline Project” and its performance is proven. With this welding machine the welding parameters can be either preset before or adjusted in real time during the welding process, which avoids the blemishes of same type domestic and international products. Thus it is best propitious to in-situ construction conditions and workers‘ technical level in China. In this article the development of mechanical and control systems of this product is introduced and typical welding procedure parameters are provided.
