脉压:心脑血管疾病的独立危险因子

脉压的大小是反映动脉粥样硬化的一个指标,因此,脉压增宽可以预测心脑血管疾病的发生,脉压预测的脑血管疾病危险的价值大于收缩压和舒张压,并有助于解释以往研究中舒张压与病死率关系不一致的现象.

2型糖尿病大血管病变机理和糖尿病治疗

2型糖尿病大血管病变与代谢综合征密切相关.现代医学认为两者的根本原因是胰岛素抵抗,导致糖耐量下降,血脂紊乱,高胰岛素血症,高血压和高凝状态等.从系统论的观点阐述了代谢综合征的相互关系和2型糖尿病大血管病变发病机理,并进一步从该观点阐明2型糖尿病的防治策略.     

重新构建先天性心脏病的学科新模式

现有先天性心脏病防治模式存在明显不足.为了更加有利于患者的治疗及先心病的学科发展,建议重新构建先心病学科新模式,将先心病独立成科,内外科融为一体,使先心病学科向专业化发展.

Posttraumatic Growth in the Context of Heart Disease

The concept of positive consequences arising as a result of coping with traumatic experiences, such as life-threatening illness, represents an emerging area of empirical study in the stress and health literature. This study investigates three specific psychosocial variables (personality, social support, and coping) in relation to posttraumatic growth in a population of individuals coping with heart disease. The results indicate that Extraversion was the most significant predictor of growth, and there is evidence that Problem-Focused Coping partially mediated this relationship between Extraversion and posttraumatic growth. The role of Social Support Satisfaction in predicting growth remains unclear. Findings emphasize the importance of personal and environmental factors in psychological interventions aimed at improving the adjustment and posttraumatic growth of heart patients. Directions for future research are proposed.     

An evolutionary system for neural logic networks using genetic programming and indirect encoding

Nowadays, intelligent connectionist systems such as artificial neural networks have been proved very powerful in a wide area of applications. Consequently, the ability to interpret their structure was always a desirable feature for experts. In this field, the neural logic networks (NLN) by their definition are able to represent complex human logic and provide knowledge discovery. However, under contemporary methodologies, the training of these networks may often result in non-comprehensible or poorly designed structures. In this work, we propose an evolutionary system that uses current advances in genetic programming that overcome these drawbacks and produces neural logic networks that can be arbitrarily connected and are easily interpretable into expert rules. To accomplish this task, we guide the genetic programming process using a context-free grammar and we encode indirectly the neural logic networks into the genetic programming individuals. We test the proposed system in two problems of medical diagnosis. Our results are examined both in terms of the solution interpretability that can lead in knowledge discovery, and in terms of the achieved accuracy. We draw conclusions about the effectiveness of the system and we propose further research directions.     

试论“肝病传脾”的诊断及治疗思路

《金匮要略》中“肝病传脾”的思想,广泛应用于临床诊断与治疗,本文以脏腑经络辨证论治思想为依据,探讨中医诊断肝痛的思路：根据症状判断病位深浅,肝病见四肢疲乏为病轻、肝病见食不消化甚至不思饮食为病重。由此判断病情轻重,为临床提供治疗依据。     

颈动脉病变的治疗现状

颈动脉病变尤其是颈动脉狭窄治疗上的分歧,颈动脉内膜切除术受欧美学者推崇,颈动脉支架成形技术受国内学者青睐,本文就近年来的文献复习发现颈动脉内膜切除术和颈动脉支架成形术各有相宜的适应证,各有优缺点,根据各自医院的设备条件、医师对颈动脉内膜切除术和颈动脉支架成形术熟悉程度来开展工作,对颈动脉狭窄治疗均有益处,存在的问题和困...
