RESUMO
0.05). Similarly, no significant difference was detected in retinal arteriolar tortuosity (Z=0.91) and venular tortuosity (Z=1.31) (both p>0.05). However, the retinal arteriolar FD (mean difference: −0.03, 95% CI: −0.05, −0.01) and venular FD (mean difference: −0.03, 95% CI: −0.05, −0.02) were associated with cognitive impairment.CONCLUSIONS: A smaller retinal microvascular FD might be associated with cognitive impairment. Further large-sample and well-controlled original studies are required to confirm the present findings.

Diabetes mellitus is a chronic disease, it is thus necessary for its patients to participate in its treatment and self-management. The emerging foreign and domestic methods for self-management of diabetes mellitus pa-tients were detected on different Websites and suggestions were proposed for its treatment and self-management in order to improve the quality of life in diabetes mellitus patients.
RESUMO
The unbalanced allocation and sharing of medical and health information resources have retrained the medical and health information construction in China. The current allocation of medical and health information re-sources was thus summarized in this paper by analyzing the CNKI. net-covered literature on medical and health in-formation, the number of undergraduates in colleges and universities, the number of employed medical and health information professionals in Eastern, Central and Western China, and in different provinces of China using the RSR, and suggestions were put forward for the development of medical and health cause in our country.
RESUMO
The paper discusses the evidence-based decision-making framework for medical insurance reimbursement based on big data concept through expert consultation,defines the dimension of decision-making,analyzes the evidence-based decision-making steps in combination with big data resources,proposes suggestions on how to make full use of big data resources around medical insurance decision-making practice.
RESUMO
The scientificalness of page quality assessment was improved by adding the page vote fraction and the user satisfaction with page according to the time perception-based PageRank Algorithm. The individualized retrieval was realized by adding the users-interested model that was matched with page types and by moving up the users-interested page rank.
RESUMO
By using the software CiteSpace Ⅱ,the paper makes a quantitative analysis and interpretation of research literatures on telemedicine in SCIE of Web of Science from three perspectives,namely the research hotspots,knowledge base and research fronts.The research hotspots of telemedicine mainly include tele-diagnosis,tele-monitoring and evaluation of the application effects of telemedicine.It sets forth key literatures representing the knowledge base one by one and reveals that most of them focus on clinical applications.The analysis of burst terms indicates that more attention has been paid to tele-monitoring and distance education of chronic diseases in recent years and mobile technology is one of the greatest driving forces for the development of telemedicine at the present stage.
RESUMO
The gap between foreign and domestic medical and health information construction levels was described and the major factors that influence the domestic medical and health information construction level were analyzed by analyzing the medical and health information construction levels in USA, Britain, Canada, Germany, Japan, Aus-tralia and China according to the input-output data in WIOD, with suggestions put forward for the improvement of domestic medical and health information construction.
RESUMO
Clinic expert information provides important references for residents in need of hospital care. Usually, such information is hidden in the deep web and cannot be directly indexed by search engines. To extract clinic expert information from the deep web, the first challenge is to make a judgment on forms. This paper proposes a novel method based on a domain model, which is a tree structure constructed by the attributes of search interfaces. With this model, search interfaces can be classified to a domain and filled in with domain keywords. Another challenge is to extract information from the returned web pages indexed by search interfaces. To filter the noise information on a web page, a block importance model is proposed. The experiment results indicated that the domain model yielded a precision 10.83% higher than that of the rule-based method, whereas the block importance model yielded an F₁ measure 10.5% higher than that of the XPath method.

Medical informatics is a science dealing with the storage,retrieval and optimal use of information, data and knowledge of biomedicine so that decisions could be made and problems solved in the process of health management, clinical control and knowledge analysis. It is an interdisciplinary subject involving the sciences of information technology and medical health, the former being its methodology and the latter its sphere of application. By analyzing the history., current situation and future challenges of medical informatics, the paper discusses the development strategies for medical informatics in China. In order to put the development of medical mformafics in China in line with international standards and make it fit in with the needs of modern society, it is imperative to speed up the training of a contingent of personnel in medical informatics, step up international and domestic cooperation and exchanges, give priority to research on the theories and applications of basic medical informatics, and establish and perfect a series of relevant criteria.
