医学科技的负面效应

论述了近代以来医学技术进步带来的负面效应。这些负面影响的存在，说明加强医疗领域的科技行为规范与科学的社会控制，对医学技术加以改良，已势在必行。     

预选技术在病历管理系统中的应用

动态《全病历计算机管理系统》一个鲜明的特色就是预选技术得到全面发挥性应用，预选病历有助于解决病历书写的自动化、快速化、标准化。医嘱预选、药物预选、方剂预选保持了系统内部的一致性，并大大地简化了操作，减少了击键次数，原先繁琐、复杂的工作变得轻松自如。预选技术化难为易，化繁为简，化不能为可能，化平凡为神奇。     

Significance of release technology in tissue engineering

Regenerative medical therapy has been expected to compensate for the therapeutic disadvantages of reconstructive surgery and organ transplantation, as well as offering a new therapeutic strategy. The objective of regenerative medical therapy is to induce the repair of defective tissues based on the natural healing potential of patients. For successful tissue regeneration, it is indispensable to provide cells with a local environment of artificial extracellular matrix where they can proliferate and differentiate efficiently. Tissue engineering is the key to this regeneration environment; release technology often enhances the in vivo stability of growth factors and related genes and prolongs the maintenance of biological functions for tissue regeneration.

基于信息技术的门诊流程改造实践与探讨

目的：通过对某医院门诊流程改造的实践研究,探讨基于医院信息系统的门诊流程改造的方法和作用. 方法：利用信息技术对现有流程进行重组,减少环节、分流“高峰”、解除“瓶颈”、构建方便、快捷、优质、高效、低耗的门诊新流程. 结果：门诊流程得到明显优化,提高了工作效率和病人满意度. 结论：门诊流程改造必须坚持“以人为本”的指导思想,以信息技术为手段,敢于打破常规,创新诊疗模式,加强科学管理,确保服务质量.     

The increased incidence of intraabdominal infections in laparoscopic procedures: potential causes, postoperative management, and prospective innovations

We conducted a review of the literature to identify some potential causes for the increased incidence of intraabdominal infections seen after laparoscopic procedures. We also discuss the postoperative management of this condition and provide a prospective overview of innovations that may be helpful in such cases in the future.     

Remote working: survey of attitudes to eHealth of doctors and nurses in rural general practices in the United Kingdom

BACKGROUND: Health professionals in rural primary care could gain more from eHealth initiatives than their urban counterparts, yet little is known about eHealth in geographically isolated areas of the UK. OBJECTIVE: To elicit current use of, and attitudes towards eHealth of professionals in primary care in remote areas of Scotland. METHODS: In 2002, a questionnaire was sent to all general practitioners (n=154) in Scotland's 82 inducement practices, and to 67 nurses. Outcome measures included reported experience of computer use; access to, and experience of eHealth and quality of that experience; views of the potential usefulness of eHealth and perceived barriers to the uptake of eHealth. RESULTS: Response rate was 87%. Ninety-five percent of respondents had used either the Internet or email. The proportions of respondents who reported access to ISDN line, scanner, digital camera, and videoconferencing unit were 71%, 48%, 40% and 36%, respectively. Use of eHealth was lower among nurses than GPs. Aspects of experience that were rated positively were 'clinical usefulness', 'functioning of equipment' and 'ease of use of equipment' (76%, 74%, and 74%, respectively). The most important barriers were 'lack of suitable training' (55%), 'high cost of buying telemedicine equipment' (54%), and 'increase in GP/nurse workload' (43%). Professionals were concerned about the impact of tele-consulting on patient privacy and on the consultation itself. CONCLUSIONS: Although primary healthcare professionals recognize the general benefits of eHealth, uptake is low. By acknowledging barriers to the uptake of eHealth in geographically isolated settings, broader policies on its implementation in primary care may be informed.     

Expectation of pregnancy outcome among mature women

OBJECTIVE: Increasing numbers of mature women are achieving pregnancy largely through assisted reproductive technology (ART). Our objective was to investigate women over 45 years of age to determine the impact of pregnancy complications on newborn outcome. STUDY DESIGN: A study of women older than 45 years at their estimated date of confinement (EDC) was compared with a control group under 36 years at their EDC, matched by parity and plurality. All study patients and controls received uniform obstetric management through a single maternal fetal practice. The primary outcome was gestational age at birth stratified by plurality; secondary outcomes included birth weight, NICU days, composite neonatal morbidity, and a variety of obstetric complications. Wilcoxon signed rank and McNemar's tests were used as appropriate; logistic regression was used to calculate odds ratios (ORs) and CIs. Statistical significance was assumed for P < .05. RESULTS: Fifty study and control patients were identified over a 5-year period. Study patients were older than controls, but the difference in "gamete" age was not significant. There was significantly more assisted reproduction (donor egg) and preeclampsia among study patients. Importantly, gestational age at birth and birth weights stratified by plurality were not different (86% power to detect 2-week gestational age difference, alpha 0.05). Hospital days, NICU days, and composite neonatal morbidity were not different between study patients and controls. CONCLUSION: When controlled for parity and plurality, mature women over 45 years conceiving largely through ART with donor eggs can expect newborn outcomes similar to younger women cared for in the same setting of a high-risk maternal-fetal practice.     

Reduction of absorbed dose in storage phosphor urography by significant lowering of tube voltage and adjustment of image display parameters

Purpose: To investigate whether image quality in storage phosphor urography can be maintained when the X-ray tube voltage is significantly lowered to give a lower patient dose.

Material and Methods: Initial phantom studies were used to establish exposure settings at 53 kV that gave signal-to-noise ratios for contrast media structures equivalent to those obtained at the reference kilovoltage of 69 kV. Dose area product and image quality, assessed by image quality criteria and visual grading, were then recorded for 44 patients drawn at random to be examined by either the standard or modified technique.

Results: Absorbed dose could be reduced by more than 30% without any significant change in image quality in manually controlled exposures and by 13% in exposures controlled by AEC.

Conclusion: It might be possible to lower the tube voltage in digital examinations involving contrast media as a means of lowering patient dose. The image display parameters need to be adjusted to maintain image quality.
