Objective To suggest the establishment a publication plan for emergency situations in order to better manage and control information to the outside environment based on the experience of front-line hospital of grade III level A in Deyang during the response to the Wenchuan earthquake. Method We systematically collected statistical information published in the forms of news, columns, newspapers, periodicals, statistics, brief massage sent out by China Telecom ans China Mobile and banners in various media (CCTV, Sichuan TV, and inside hospital etc.) after Wenchuan earthquake.Result Within 40 days after the Wenchuan Earthquake, the People’s Hospital of Deyang City had reported rescue information for 181 times, sent 1 600 000 phone messages to the public, issued 7 476 pieces of family-search information, distributed 1 486 earthquake first-aid brochures, distributed 1 750 psychological brochures, compiled 12 periodicals called “Special Report for Earthquake Relief Effort”, and finished 3 periodicals called “Special Issue for Earthquake Relief Effort”; issued 319 articles, over 200pictures and videos on websites inside and outside of the hospital; issued over 60 pieces of news and 7 special topic documentaries in CCTV etc.; and issued over 70 pieces of news on People’s Daily. Conclusion During the Wenchuan earthquake, the People’s Hospital of Deyang City shows the rescue work to the public via effective publication mechanisms. News and information is transmitted fast and effectively between people from both upper and lower levels. However, there are weaknesses in working mechanisms and methods, which requires further study and consideration.
Computer-aided detection (CAD) of pulmonary nodule technology can effectively assist the radiologist to enhance lung nodule detection efficiency and accuracy rate, so it can lay the foundation for the early diagnosis of lung cancer. In order to provide reference for the scholars and to develop the CAD technology, we in this paper review the technology research and development of CAD of the pulmonary nodules which is based on CT image in recent years both home and abroad. At the same time, we also analyse the advantages and shortcomings of different methods. Then we present the improvement direction for reference. According to the literature in recent years, there still has been large development space in CAD technology for pulmonary nodules. The establishment and improvement of the CAD system in each step would be of great scientific value.
The mechanical properties of artificial intervertebral disc (AID) are related to long-term reliability of prosthesis. There are three testing methods involved in the mechanical performance evaluation of AID based on different tools: the testing method using mechanical simulator, in vitro specimen testing method and finite element analysis method. In this study, the testing standard, testing equipment and materials of AID were firstly introduced. Then, the present status of AID static mechanical properties test (static axial compression, static axial compression-shear), dynamic mechanical properties test (dynamic axial compression, dynamic axial compression-shear), creep and stress relaxation test, device pushout test, core pushout test, subsidence test, etc. were focused on. The experimental techniques using in vitro specimen testing method and testing results of available artificial discs were summarized. The experimental methods and research status of finite element analysis were also summarized. Finally, the research trends of AID mechanical performance evaluation were forecasted. The simulator, load, dynamic cycle, motion mode, specimen and test standard would be important research fields in the future.
