RESUMO
Objective:To investigate the clinical effect of enteral nutrition (EN) on patients with acute exacerbation of chronic obstructive pulmonary disease (COPD).Methods:96 cases of acute exacerbation of COPD patients admitted to our hospital from January 2015 to December 2016 were randomly divided into observation group (48 cases) and control group (normal diet,48 cases).The patients in two groups were given anti-infection and other symptomatic treatments equally.The serum protein levels and pulmonary function in the two groups were compared after 2 weeks.Furthermore,antibiotic use durations,hospitalization days and the re-admission rates within 3 months were observed and compared between two groups.Results:The serum albumin and pre-albumin levels,FEV1 and FEV1/FVC in the observation group were significantly elevated in comparison with those in the control group.And the antibiotic use durations,hospitalization days and the re-admission rates within 3 months remarkably decreased in the observation group (P ＜ 0.05).Conclusion:Enteral nutrition could improve the nutritional status and pulmonary function in patients with acute exacerbation of COPD,shortening the length of hospital stay and the durations of antibiotic use and reducing the rates of re-admission.Enteral nutrition may be worth applying widely in clinical COPD patients in future.
RESUMO
In this paper, the theory of complex adaptive system (CAS) and its modeling method are introduced. The complex characters of the hospital system is analyzed. The agile manufacturing and cell reconstruction technologies are used to reconstruct the hospital system. Then we set forth a research for simulation of hospital system based on the methodology of Multi-Agent technology and high level architecture (HLA). Finally, a simulation framework based on HLA for hospital system is presented.

Objective The present study was designed to investigate changes in serum or plasma concentrations of nitric oxide and its derivatives in diabetic patients.Methods Serum nitrate concentration of 84 diabetic patients was measured by using an enzyme kinetic method,and the plasma S-nitrosothiols concentration of 10 cases was measured by using HPLC technique.Results Serum nitrate concentration and plasma S-nitrosothiols concentration in the diabetics were significantly higher than in control group (P＜0.01 andP＜0.05,respectively).The serum nitrate concentration in diabetics also had a significant positive correlation with the serum glucose concentration (R=0.7256,P＜0.05),but this correlation was not found in control group.Conclusion These data showed that NO and its derivatives are overproduced in the diabetic patients.(J Geriatr Cardiol 2008;5:25-27)
RESUMO
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.
RESUMO
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.
RESUMO
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.

RESUMO
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.
