正交试验法优选心脑安胶囊提取工艺

用正交试验法对心脑安胶囊的制备工艺进行了探讨。用正丁醇浸出物含量为指标,考察了加水量、浸泡时间、煎煮时间、煎煮次数４种因素对其提取效果的影响。结果表明,加水量的多少是影响切药材煎煮效果的主要因素,为了保证有效成分的煎出,心脑安胶囊拟采用１３倍量水,浸泡１２ｈ,煎煮２次,每次１．５ｈ为宜。

Percutaneous retrieval of an impacted ureteric T-tube

An impacted ureteric T-tube was removed percutaneously, using an Amplatz goose-neck snare. This new snare has advantages over conventional snares, particularly in situation where atraumatic manipulation is essential. Correspondence to: R. D. Edwards     

Modell eines computergestützten qualitätssicherungssystems in der verbrennungsintensivtherapie

Zusammenfassung Ausgehend von Überlegungen für ein angemessenes Qualitätssicherungssystem im intensiv-medizinischen Bereich werden die Voraussetzungen für ein ganzheitliches Qualitätsmanagementsystem im Krankenhaus entworfen. Die Grundlage für ein dynamisches Qualitätssicherungssystem ist auf der dokumentatorischen Ebene eine umfassende Datenbasis, die auf einer zeitlich und datentechnisch unbegrenzten Patientenakte basiert. Die notwendige Hard- und Softwarestruktur wird durch die konsequente Anwendung einer Client-Server-Architektur gewährleistet. Die ständige Überprüfung der bestehenden Qualitätsziele in einem ökonomischen Regelkreis benötigt ein System mit flexiblen Abfragemechanismen. Dieser informatorische Datenzugriff auf jeder Hierarchieebene der Krankenhausstruktur wird durch das Konzept des Data-Warehouse ermöglicht, das als Datenbanksystem mit subjektorientierten, integrierten, zeitvariablen und beständigen Informationen konzipiert ist.

A computer-assisted quality-assurance model for burn intensive care applications

The prerequisites for an integrated quality management system for hospitals were developed as a result of considerations regarding the necessity of an appropriate quality-assurance system for the intensive care sector. The basis for a dynamic quality-assurance system on the documentational level is a comprehensive data base containing patient files unlimited in terms of time and data technology. The necessary hardware and software structure will be provided by consistent application of a client-server architecture. Permanent surveillance of existing quality objectives within the scope of an economic close-loop system requires a system with flexible query mechanisms. Informational data access from all hierarchical level within the hospital organization is facilitated by the data warehouse concept, a data base system with subject-oriented, integrated, time-variable, and persistent data.

     

Digital psychiatry

The American managed care movement has been viewed as a big experiment and is being watched closely by the rest of the world. In the meanwhile, computer-based information technology (IT) is changing the practice of medicine, much more rapidly than managed care. A New World of digitized knowledge and information has been created. Although literature on IT in psychiatry is largely absent in peer-reviewed psychiatric journals, IT is finding its way into all aspects of medicine, particularly psychiatry. Telepsychiatry programs are becoming very popular. At the same time, medical information sites are flourishing and evolving into a new health-care industry. Patient-physician information asymmetry is decreasing as patients are gaining easy access to medical information hitherto only available to professionals. Thus, psychiatry is facing another paradigm shift, at a time when most attention has been focused on managed care. In this new digital world, knowledge and information are no longer the sole property of professionals. Value will migrate from traditional in-person office-based therapy to digital clinical products, from in-person library search and classroom didactic instruction to interactive on-line searches and distance learning. In this time of value migration, psychiatrists have to determine what their 'distinctive competence' is and where best to add value in the health-care delivery value chain. The authors assess the impact of IT on clinical psychiatry and review how clinical practice, education and research in psychiatry are expected to change in this emerging digital world.

In vitro evaluation study of the membrane autotransfusion system experimental prototype: MATS-I

Abstract: Membrane Autotransfusion System (MATS) utilizing plasmapheresis technology has been developed in our laboratory. A specially designed polyethylene hollow fiber membrane was utilized. This study was conducted to evaluate performance of the first experimental prototype, MATS-I. The results of this study showed that the MATS-I could concentrate diluted blood at 10% of the initial hematocrit concentration (HCTi) into over 40% after passing through the system at a transmembrane pressure of 70 mm Hg. Moreover, the MATS-I can continuously treat 10,000 ml of diluted blood at various HCTi levels without deteriorating its performances. Even though the MATS-I met all required performances as an autotransfusion system, several areas of improvement of the system were necessary to meet various clinical needs. The next prototype, MATS-II, can be designed based on experiences obtained from the MATS-I. The MATS is smaller, more atraumatic and continuous, and is a faster system when compared to the currently available centrifugal autotransfusion devices.     

试论方剂功效表达的历史沿革及现代研究意义

方剂的历史悠久，但真正将方剂作为研究对象，出现方剂功效的描述则始自金代成无己，并在明清时期有了较大的发展，而直到建国后才形成一定的规范。目前古方中还存在大量的方荆只有简单的组成与主治，而没有详细的方论，包括方剂功效。文章最后论述了方荆功效理论研究的重要性与可行性。

教育技术现代化的内部动因

在教育技术现代化的历史进程中 ,教育技术理论的发展有着特殊的地位 ,它既是教育技术现代化的重要组成部分 ,又是教育技术现代化的重要依据和推动力量。在发展过程中 ,教育技术一方面在自己的实践过程中加强研究与总结用以指导自己实践的规律 ,一方面从教育学、心理学、传播学、系统论、控制论、信息论等有关领域的研究成果中汲取营养 ,实现自己的理论扩展 ,又反过来指导教育技术实践 ,教育技术就在这认识———实践———再认识———再实践的往复循环中不断提高和发展。
