中药治疗颈淋巴结核28例简介

颈淋巴结核是感染结核杆菌所致,多发于青少年,祖国医学称为“瘰疬”,俗称:“老鼠症”。笔者自1994年至2004年用民间单方治疗28例颈淋巴结核,疗效满意,现介绍如下:方剂:穿山甲、蛇蜕各3钱,鱼鳔30g,乳香、没药各3钱,生鸡蛋5个(去壳,取蛋清和蛋黄搅拌均匀),香油半斤。制法和用量:用香油炸药,下药次序是:穿山甲、蛇蜕、鱼鳔、鸡蛋,后炸乳香、没药,药要炸到黄变焦为度(此时油已基本耗完),炸后,把诸药混合捣成泥状为1剂。每日3次,每次服1匙,以上剂量于1周服完。用药指征:凡确诊为颈淋巴结核早期有紧硬块,或晚期已成无热脓肿溃溃者,均可应用。临床观察:28例患者中,有25例系早期患者,颈部仅有串珠样,可移动,无明显压疼,大小不等的结节状淋巴结核,3例为晚期,已成无脓肿溃破,并已造成瘘管。28例中13例服1剂,6例服3例而愈(痊愈标准:硬结消散,溃破处瘘管愈合)。18例访随半年,7例随访1年,1例随访1年半,均未复发,2例因失去地址未随访。28例在接受本法治疗过程中,均未用抗痨药物,有溃破的患者,仅作局部清洁和换药。举例:祝某,女,25岁,颈部串珠结节2年,溃破流脓8个月,在某医院诊断为“颈淋巴结核”。长期服用雷米...     

亚胺培南和左氧氟沙星治疗方案蒙特卡洛模拟的比较

依据抗菌药物的药动学/药效学原理,本文建立蒙特卡洛模拟模型,优化比较亚胺培南/西司他丁(剂量以亚胺培南计)和左氧氟沙星抗感染治疗的给药方案。模拟试验表明,亚胺培南0.5 g/8 h静脉滴注对鲍曼不动杆菌、肺炎克雷伯菌感染的疗效较好,累积反应分数(CFR)分别为97.28%和99.71%;对铜绿假单孢菌,低剂量的CFR不够理想,增大剂量可以提高CFR,但低于90%,提示经验治疗时须考虑联合用药。左氧氟沙星静脉滴注0.2g/d对卡他莫拉菌有效,CFR为100%;对肺炎克雷伯菌,0.2g/d、0.3 g/d、0.5g/d和0.75 g/d各治疗方案的CFRs相近,约为55%,增加剂量未能增强效果;对肺炎链球菌,0.5g/d的日剂量CFR达100%,可具有治疗效果。蒙特卡洛模拟可预测和优化抗菌药的用药设计,帮助临床选择合适的抗感染治疗方案。

绿蝽象(Nezara、iridula L.)是阿尔及利亚大豆生产上危害严重的害虫之一。绿蝽象除危害大豆外,还危害菜豆、蕃茄、黄瓜、冬瓜、白菜、紫云英和苋菜、龙葵,曼陀萝等多种作物和植物,根据169头成虫分析,雌雄性比为1:1;绿色型、镶边型与黄带型的自然比例分别为52.7％、33.1％和14.2％。调查32个卵块,平均母块卵里有卵92.76粒;7月份由卵发育成成虫的历期23天,详述了各龄若虫的形态、习性及其历期。温度高、湿度大和寄主生长繁茂时,则虫量大且危害重。倍硫磷、甲基1605和灵丹份对大豆无药害但药效好;倍硫磷的400倍可液兼治红蜘蛛,200倍液可兼治斜纹夜蛾,拖拉机牵引喷药机械施药,比人工施药速度快、省药且防效好。     

Only connect: teaching, technology and telesis

Abstract This paper describes an approach to the design of interactive multimedia materials being developed in a European Community project. The developmental process is seen as a dialogue between technologists and teachers. This dialogue is often problematic because of the differences in training, experience and culture between them. Conditions needed for fruitful dialogue are described and the generic model for learning design used in the project is explained.     

European Community policy and the market

Abstract This paper starts with some reflections on the policy considerations and priorities which are shaping European Commission (EC) research programmes. Then it attempts to position the current projects which seek to capitalise on information and communications technologies for learning in relation to these priorities and the apparent realities of the marketplace. It concludes that while there are grounds to be optimistic about the contribution EC programmes can make to the efficiency and standard of education and training, they are still too technology driven.     

一种自适应子融合集成多分类器方法

融合集成方法已经广泛应用在模式识别领域,然而一些基分类器实时性能稳定性较差,导致多分类器融合性能差,针对上述问题本文提出了一种新的基于多分类器的子融合集成分类器系统。该方法考虑在度量层融合层次之上通过对各类基多分类器进行动态选择,票数最多的类别作为融合系统中对特征向量识别的类别,构成一种新的自适应子融合集成分类器方法。实验表明,该方法比传统的分类器以及分类融合方法识别准确率明显更高,具有更好的鲁棒性。     

Avoiding semantic and temporal gaps in developing software intensive systems

Development of software intensive systems (systems) in practice involves a series of self-contained phases for the lifecycle of a system. Semantic and temporal gaps, which occur among phases and among developer disciplines within and across phases, hinder the ongoing development of a system because of the interdependencies among phases and among disciplines. Such gaps are magnified among systems that are developed at different times by different development teams, which may limit reuse of artifacts of systems development and interoperability among the systems. This article discusses such gaps and a systems development process for avoiding them.     

Designing economic np control charts: A programmed simulation approach

This paper presents control charts models and the necessary simulation software for the location of economic values of the control parameters. The simulation program is written in FORTRAN, requires only 10K of main storage, and can run on most mini and micro computers. Two models are presented - one describes the process when it is operating at full capacity and the other when the process is operating under capacity. The models allow the product quality to deteriorate to a further level before an existing out-of-control state is detected, and they can also be used in situations where no prior knowledge exists of the out-of-control causes and the resulting proportion defectives.     

The development of robot art

Going through a few examples of robot artists who are recognized worldwide, we try to analyze the deepest meaning of what is called “robot art” and the related art field definition. We also try to highlight its well-marked borders, such as kinetic sculptures, kinetic art, cyber art, and cyberpunk. A brief excursion into the importance of the context, the message, and its semiotics is also provided, case by case, together with a few hints on the history of this discipline in the light of an artistic perspective. Therefore, the aim of this article is to try to summarize the main characteristics that might classify robot art as a unique and innovative discipline, and to track down some of the principles by which a robotic artifact can or cannot be considered an art piece in terms of social, cultural, and strictly artistic interest. This work was presented in part at the 13th International Symposium on Artificial Life and Robotics, Oita, Japan, January 31–February 2, 2008

Explanation and prediction: an architecture for default and abductive reasoning

Although there are many arguments that logic is an appropriate tool for artificial intelligence, there has been a perceived problem with the monotonicity of classical logic. This paper elaborates on the idea that reasoning should be viewed as theory formation where logic tells us the consequences of our assumptions. The two activities of predicting what is expected to be true and explaining observations are considered in a simple theory formation framework. Properties of each activity are discussed, along with a number of proposals as to what should be predicted or accepted as reasonable explanations. An architecture is proposed to combine explanation and prediction into one coherent framework. Algorithms used to implement the system as well as examples from a running implementation are given.     

Three Process Perspectives: Organizations, Teams, and People

This paper provides the author's personal views and perspectives on software process improvement. Starting with his first work on technology assessment in IBM over 20 years ago, Watts Humphrey describes the process improvement work he has been directly involved in. This includes the development of the early process assessment methods, the original design of the CMM, and the introduction of the Personal Software Process (PSP)^SM and Team Software Process (TSP){^SM}. In addition to describing the original motivation for this work, the author also reviews many of the problems he and his associates encountered and why they solved them the way they did. He also comments on the outstanding issues and likely directions for future work. Finally, this work has built on the experiences and contributions of many people. Mr. Humphrey only describes work that he was personally involved in and he names many of the key contributors. However, so many people have been involved in this work that a full list of the important participants would be impractical.     

基于复小波噪声方差显著修正的SAR图像去噪

提出了一种基于复小波域统计建模与噪声方差估计显著性修正相结合的合成孔径雷达(Synthetic Aperture Radar,SAR)图像斑点噪声滤波方法。该方法首先通过对数变换将乘性噪声模型转化为加性噪声模型,然后对变换后的图像进行双树复小波变换(Dualtree Complex Wavelet Transform,DCWT),并对复数小波系数的统计分布进行建模。在此先验分布的基础上,通过运用贝叶斯估计方法从含噪系数中恢复原始系数,达到滤除噪声的目的。实验结果表明该方法在去除噪声的同时保留了图像的细节信息,取得了很好的降噪效果。
