With the development of network and information in hospital,the issue of security has been raised and got more and more important.This article describes the factors that might threaten the network and information security,such as the reliability of network equipments,computer viruses,invalid intrusion,the security of inner-network,the thunder,users' actions and so on.Then some solutions to the problems are proposed.This could be an instruction to design or update the hospital's network and information system.

Objective To develop ICU digital system for over-all monitoring and remote monitoring.Methods The programming and design was performed according to the principles of"taking patients as center,clinic as basis,utility as goal,service as aim".Results ICU digital system was composed of digital medical instruments and their clinical Gateway,intensive care information system,bedside integrated clinical information terminals,nurse workstation integrated clinical information terminals,serious patients visit system,little smart local communication system,consultation demonstration teaching system and personal digital assistant clinical information terminal system.Conclusion As one of the important symbols of modern hospital,the ICU digital system integrates the vital signs information of every patient in ICU and implement seamless connection with CIS,LIS,PACS,HIS.The construction of ICU digital system will accelerate the digital hospital's development.

Hand, foot, and mouth disease (HFMD) is a viral infectious disease regarded to be a public-health problem worldwide. Since the 1990s, HFMD began to spread in the Asia-Pacific region (especially in South-East Asia). HFMD outbreaks have occurred in mainland China frequently since 2008, and the morbidity and mortality of HFMD has continued to increase in recent years. In mainland China, enterovirus A serotype enterovirus A71 (EV-A71) and coxsackievirus A16 (CVA16) have been the major pathogens of HFMD during these years. However, the etiological spectrum of HFMD changes with time. This review focuses mainly on the etiological spectrum of HFMD and changes in epidemic patterns in mainland China.

Objective:To explore the mental health status of the first-degree relatives of the heroin addicts. Methods: Three hundred twenty first-degree relatives of the heroin addicts were evaluated with SCL-90. Results: The scores of somatization, depression, anxiety, paranoia, and psychiatric factor among the first-degree relatives were significantly higher than the national norm. The first-degree relatives of heroin addicts who had addicted more than 5 years had significantly higher score than the relatives of heroin addicts who had addicts less than 5 years. Conclusion: The mental health condition of the first-degree relatives of heroin addicts was poor, especially those relatives of heroin addicts who have addicted for more than 5 years.

Objective To investigate the effects of non-ionic low osmolar contrast media (LOCM) on the apoptosis and mRNA expression of Bcl-2/Bax in rat glomerular endothelial cells cultured in vitro. Methods Rat glomerular endothelial cells were exposed to ioversol with different concentrations for different time. Cell viability was then assessed by MTT method and morphological changes of cells were observed by inverted microscopy. In order to analyze cell apoptosis, DNA electrophoresis was applied. Meanwhile, the expression changes of Bcl-2/Bax at mRNA level were determined by RT-PCR. Results The viability of rat glomerular endothelial cells was inhibited by ioversol in a concentration and time dependent manner. After being exposed to ioversol(90 mL/L)for 24 h, the cells began to become crimple, round, and even floating. A typical DNA ladder determined by agarose gel electrophoresis was observed. Noticeably, the mRNA level of Bcl-2 in ioversol treated cells was down-regulated, while Bax was up-regulated, so that the ratio of Bcl-2 mRNA to Bax mRNA increased significantly. Conclusion Non-ionic LOCM can induce glomerular endothelial cells apoptosis, which may be partly due to the disturbance of Bcl-2/Bax balance. This is probably related to the pathogenesis of contrast media nephropathy.

The backward condition of clinical and fundamental investigation of diabetic retinopathy was unfit for the fast increasing diabetic patients and the high incidence of diabetic retinopathy. A database software of diabetic retinopathy, was developed. The system using windows 9x/NT has six functions as follows: patients′ general situation, examination table, checking picture index and users′ administration. The characteristics of the sole criterion, accuracy, continuity, completeness, frequency, different comparison, annexing the functions of computer based patient record which are profitable for long distance consultation and training.

ObjectiveTo investigate the clincal status and countermeasures for intensive care unit (ICU) hospital deep fungal infections.Methods108 cases of ICU hospital deep fungal infections patients were divided into comprehensive treatment group and converntional treatment group,54 cases in each group.The morbidity and treatment effects were observed.ResultsThe cure rate of observation group was 96.3％,significantly higher than 79.6％in control group.The observation group complication rate was 9.2％,significantly lower than the control group 20.4％,the difference was significant (P ＜ 0.05 ).ConclusionIn the ICU nosocomial fungal infection treatment,the scientific and effective means of comprehensive prevention and control best practices,could significantly improve patient outcomes,improve treatment,reduce hospital stay and reduce complications.

According to information interchange situation in our hospital,this article analyzes and discusses the PHS,GSM,CDMA and DECT technologies,selects the PHS technology to construct hospital mobile communication system for the better construction of hospital information interchange environment.

The ultrasound devices have been widely applied in hospitals.The audio & video teaching system for ultrasonic diagnosis based on network was built for training ultrasonic diagnosis skill.The system should lay emphasis on the design of consulting room,network,server,grouping study and meeting teaching systems.The system construction and application are introduced in combination with actual experiences in hospital.
