This paper aims to design and implement a web-based medical equipment maintenance system to be used at clinical engineering department, orienting to the improvement of quality and efficiency of technology service so as to meet the 2010 regulations homologated with China's Ministry of Health. Methods: The system adopted three-layer structure based on B/S mode with oracle database and ASP.NET development technologies. Based on risk management and inclusion criteria for maintenance, the software system modules consist of hospital equipment inventory management, personnel information management, breakdown maintenance, preventive maintenance(PM) and analysis graphical representations.Results: An user friendly web interface was provided for easy and secure access to the system. Medical equipment management activities from log-in to acceptance test to maintenance services were implemented. Conclusion: The application of this system has achieved benefits for the risk management of medical equipment.展开更多

Various scaffold materials have been used in animal studies, but clinical studies on use of scaffolds for urethral repair are scarce. The aim of this study was to review recent animal and clinical studies on the use of different scaffolds for urethral repair, and to evaluate these scaffolds based on the evidence from these studies. Pub Med and OVID databases were searched to identify relevant studies, in conjunction with further manual search. Studies that met the inclusion criteria were systematically evaluated. Of 555 identified studies, 38 were included for analysis. It was found that in both animal and clinical studies, scaffolds seeded with cells were used for repair of large segmental defects of the urethra, such as in tubular urethroplasty. When the defect area was small, cell-free scaffolds were more likely to be applied. A lot of pre-clinical and limited clinical evidence showed that natural or artificial materials could be used as scaffolds for urethral repair. Urinary tissue engineering is still in the immature stage, and the safety, efficacy, cost-effectiveness of the scaffolds are needed for further study.展开更多
