Objective To design and apply the quality tracking system for central sterile supply department,complete the quality tracking of sterile medical products,rental surgical devices and high level disinfected products,conform the second-class storage management and human resource management.Methods By using the modern technology of WiFi wireless network,mobile PDA technology and two dimensional barcode,through establishing the team,collecting the data,installing the hardware,debugging the system,training and education,the development and application of the system was completed.Results The system has been operated for two years nearly in central sterile supply depamnent and other departments in hospital,it showed great practicability and convenience,covered all the daily work in central sterile supply department,achieved the information management in mobile digital way.Conclusions The application of digital mobile quality management system accelerates the central sterile supply department in standard way and realizes scientific in strategic decision and management.

It is generally accepted that Mycoplasma hominis and Ureaplasma urealyticum are primarily found in the genitourinary tract and rarely enter the tissues and bloodstream. In recent years，cases of extra-genitourinary system infections caused by Mycoplasma hominis and Ureaplasma urealyticum have been increasing with a trend of multi-drug resistance，while detection and diagnosis are difficult，leading to treatment delay clinically. This article reviews the latest research progress on the pathogenic characteristics，laboratory diagnosis，infection types，and treatment options of extra-genitourinary system infections caused by Mycoplasma hominis and Ureaplasma urealyticum，in order to provide reference for etiological diagnosis and treatment of the infection.
