Study of blood exposure-related mental health illness among clinical nurses

null

《医学前沿（英文）》 2017年第11卷第1期页码 147-151 doi: 10.1007/s11684-016-0481-8

摘要：

Nurses are subjected to high amount of stress in the medical setting, and work-related stress often leads to mental problems. This study aims to investigate the mental health status of nurses exposed to blood through needlestick injuries. A total of 302 nurses working in the hospital of Guangdong, China, participated in this study. Out of the 302 nurses, 140 did not experience any needlestick injuries during the previous week, whereas 162 nurses experienced needlestick injuries. The General Health Questionnaire (GHQ)-28 Standardized Questionnaire, which uses physical, anxiety, social function, and depression subscales, was used in this study. No significant difference between nurses exposed to blood and nurses not exposed to blood was found in terms of gender, age, length of employment, and civil status (P>0.05). Results from the GHQ-28 Standardized Questionnaire showed that 75.9% (123/162) of nurses exposed to blood were suspected to suffer from mental disorders, whereas 40% (56/140) of nurses not exposed to blood were suspected to suffer from mental disorders. The mean mental health scores of nurses exposed to blood and those not exposed were 8.73±7.32 and 5.69±5.70, respectively. From these results, we can conclude that blood exposure from needlestick injuries leads to higher prevalence of depression, anxiety, and stress symptoms in nurses. This finding highlights the importance of providing efficient, adequate, and appropriate support services after nurses are exposed to blood from needlestick injuries.

心理疲劳的神经机制——脑连接组的新见解 Review

齐鹏, 茹画, 高凌云, 张小兵, 周天舒, 田语, Nitish Thakor, Anastasios Bezerianos, 李劲松, 孙煜

《工程（英文）》 2019年第5卷第2期页码 276-286 doi: 10.1016/j.eng.2018.11.025

摘要：

在长时间的认知任务中保持注意力集中通常会引起高水平的心理疲劳。心理疲劳可以描述为一种主观疲惫的感觉，通常表现为对眼前任务参与感的降低，客观上体现为与任务相关的认知、行为执行能力和表现降低。为了有效地减少实际工作中由心理疲劳引起的不良后果，众多来自不同领域的研究者付出了持续不断的努力以进一步理解其潜在的神经机制。其中神经工程和人因工程领域的相关研究者提出了通过采用先进的脑影像技术手段，对心理疲劳产生过程中的神经活动变化进行定量分析，从而揭示其作用机理的研究思路。本文首先对有关心理疲劳的神经影像学研究成果进行了介绍，并结合脑连接图谱等新的影像学证据对这些研究中广泛使用的单变量分析方法的缺点进行了讨论。近10年来，越来越多的研究认为心理疲劳与大脑各区域之间功能连接的重组有关，而图论分析方法的提出也为定量分析功能连接重组提供了新的视角。针对这一新的研究趋势，本文较为全面地概述了心理疲劳的脑连接相关研究成果，归纳总结了多变量脑功能连接分析方法在心理疲劳神经机制研究中的意义。目前这一新兴研究领域的相关研究成果还相对较少，但脑连接组的应用不仅有助于阐明神经工效学这一新生领域中心理疲劳的潜在神经机制，而且在不久的将来有望实现心理疲劳的自动检测及分类，从而避免疲劳相关的不良后果。

Agent的PASS-BDI模型

樊玮,陈增强,袁著祉

《中国工程科学》 2004年第6卷第6期页码 43-49

摘要：

Agent的BDI模型主要基于Bratman提出的理性主体理论，未能充分体现Agent主动性的认知过程，使Agent的问题求解和心智状态之间的关系未得到充分表达，且难于编程实现。将Das等人提出的计划—注意—同时性加工—继时性加工认知过程模型引入Agent的理论研究中，建立了Agent的PASS-BDI模型，利用多价π-演算从心智状态，认知过程，整体行为等几个方面刻画了该模型的静态和动态特征，并将研究结果应用于多Agent组织中Agent行为特征的刻画。PASS-BDI模型加强了对Agent主动性认知过程的刻画，且易于编程实现。

Kan ZHANG MM, Wei DONG MM, Ying-Yao CHEN MD,

《医学前沿（英文）》 2010年第4卷第2期页码 134-138 doi: 10.1007/s11684-010-0041-6

摘要： This article discusses the concept of health management and stresses that community health management should be the starting point of community health service, necessitating a paradigm shift from observing the treatment-oriented medical model to observing the prevention-and-health management-based medical model. Community health construction has entered a new phase, one which highlights the need to train general practitioners in practice-based life cycle health management. In addition, general practitioners should assume the mission of implementing community health management.

Percolation-based health management of complex traffic systems

《工程管理前沿（英文）》 2021年第8卷第4期页码 557-571 doi: 10.1007/s42524-021-0174-0

摘要： System health management, which aims to ensure the safe and efficient operation of systems by reducing uncertain risks and cascading failures during their lifetime, is proposed for complex transportation systems and other critical infrastructures, especially under the background of the New Infrastructure Projects launched in China. Previous studies proposed numerous approaches to evaluate or improve traffic reliability or efficiency. Nevertheless, most existing studies neglected the core failure mechanism (i.e., spatio–temporal propagation of traffic congestion). In this article, we review existing studies on traffic reliability management and propose a health management framework covering the entire traffic congestion lifetime, from emergence, evolution to dissipation, based on the study of core failure modes with percolation theory. Aiming to be “reliable, invulnerable, resilient, potential, and active”, our proposed traffic health management framework includes modeling, evaluation, diagnosis, and improvement. Our proposed framework may shed light on traffic management for megacities and urban agglomerations around the world. This new approach may offer innovative insights for systems science and engineering in future intelligent infrastructure management.

Individualized medicine, health medicine, and constitutional theory in Chinese medicine

null

《医学前沿（英文）》 2012年第6卷第1期页码 1-7 doi: 10.1007/s11684-012-0173-y

摘要：

The patterns of modern science and changes in the medical model can result in the transformation of the current state of individualized and health medicines into being the primary trend in medical development. Chinese and Western medical systems are dissimilar in terms of value orientations, thinking style, and research directions because of their different historical and cultural backgrounds. Individualized treatment in modern medicine is mainly established based on individual genome information and the differences in mononucleotide polymorphi-sms. However, such treatment method is expensive, creates an uncertain genetic marker, and leads to different result interpretations, among other problems. The Chinese constitutional theory developed in the 1970s expresses the principle behind Chinese health medicine and individual treatment and provides the corresponding methods. The Chinese constitutional theory divides the constitution of the Chinese population into nine categories based on established classification criteria. It promotes the study of the relationship of each constitution to diseases and Chinese medicine preparation toward adjusting the constitution and preventing diseases. The theory also provides methods and tools for individualized treatment. Constitution identification shows the direction and provides the core technology for the evaluation of the health status. By combining the developments in modern biotechnology, new diagnostic techniques and treatment models of constitution-differentiation, disease-differentiation, and syndrome-differentiation can be established for the development of individualized Chinese medicine treatment and health medicine for the international medical community.

E-waste environmental contamination and harm to public health in China

null

《医学前沿（英文）》 2015年第9卷第2期页码 220-228 doi: 10.1007/s11684-015-0391-1

摘要：

The adverse effects of electronic waste (e-waste) on the human body have stirred up concern in recent years. China is one of the countries that confront serious pollution and human exposure of e-waste, and the majority of the population is exposed to potentially hazardous substances that are derived from informal e-waste recycling processes. This study reviews recent reports on human exposure to e-waste in China, with particular focus on exposure routes (e.g., inhalation and ingestion) and several toxicities of human (e.g., endocrine system, respiratory system, reproductive system, developmental toxicity, neurotoxicity, and genetic toxicity). Pieces of evidence that associate e-waste exposure with human health effects in China are assessed. The role of toxic heavy metals (e.g., lead, cadmium, chromium, mercury, and nickel) and organic pollutants (e.g., polybrominated diphenyl ethers (PBDEs), polychlorinated biphenyl (PCBs), polycyclic aromatic hydrocarbons (PAHs), polybrominated biphenyls (PBBs), polyhalogenated aromatic hydrocarbons (PHAHs), bisphenol A (BPA)) on human health is also briefly discussed.

Integration of current identity-based district-varied health insurance schemes in China: implications

null

《医学前沿（英文）》 2012年第6卷第1期页码 79-84 doi: 10.1007/s11684-012-0179-5

摘要：

With China’s great efforts to improve public health insurance, clear progress has been achieved toward the ambitious full health insurance coverage strategy for all. The current health insurance schemes in China fall into three categories: urban employee basic health insurance scheme, urban resident scheme, and new rural cooperative medical system. Despite their phasic success, these substantially identity-based, district-varied health insurance schemes have separate operation mechanisms, various administrative institutions, and consequently poor connections. On the other hand, the establishment and implementation of various health insurance schemes provide the preconditioning of more sophisticated social health insurance schemes, the increase in the income of urban and rural people, and the great importance attached by the government. Moreover, the reform of the “Hukou” (household register) system provides economical, official, and institutional bases. Therefore, the establishment of an urban-rural integrated, citizen-based, and nationwide-universal health insurance scheme by the government is critically important to attain equality and national connection. Accordingly, the differences between urban and rural areas should be minimized. In addition, the current schemes, administrative institutions, and networks should be integrated and interconnected. Moreover, more expenditure on health insurance might be essential for the integration despite the settings of global financial crisis. Regardless of the possible challenges in implementation, the proposed new scheme is promising and may be applied in the near future for the benefit of the Chinese people and global health.
