Objective:To explore and assess the clinical application and clinical value of dual helical CT and magnetic resonance imaging (MRI) in the diagnosis of knee bone tumor. Methods: Sixty-nine patients with knee bone tumors were randomly divided into three groups: group A, group B and group C. Group A was detected by double-helical CT scanning; group B was detected by MRI; group C was detected by dual-helical CT scan combined with MRI. After the end of the testing, the clinical diagnostic results of the three detection methods were compared.Results: There was no significant difference between group A and B (x2=0.825,P>0.05). The detection rate of group C was higher than that of group A. The differences were statistically significant (x2=2.936,x2=3.718;P<0.05). The detection rate of group C was significantly higher than that of group B. The differences were statistically significant (x2=3.967,x2=4.285;P<0.05).Conclusion: Double helical CT combined with MRI can effectively improve the clinical detection rate of knee bone tumor.

Objective:To establish the medical equipment maintenance management system based on HRP, to break through and solve various problems that the traditional manual management mode couldn't resolve in the medical equipment maintenance and repair, and to ensure the normal development of clinical diagnosis and treatment.Methods: Using the network information technology, combining with the characteristics of the hospital industry, referring to the enterprise resource planning management system, to establish a new hospital medical equipment maintenance management system.Results: The system management module included a series functions, such as maintenance reports, maintenance applications, applications for repair, maintenance grades, maintenance items, fault types and maintenance methods. This module unified the technology and methods, contents and procedures of equipment maintenance, and the system also included maintenance plan, maintenance report and early warning function for the equipment using. Besides, the design of specially displayer would real-time display maintenance information.Conclusion: HRP system was used to replace the traditional manual management mode and it can break and resolve various problems of medical equipment repair and maintenance at the present hospital, such as record and save the maintenance information, provide high efficiency and high quality service for the clinical diagnosis and treatment, and data support for statistical analysis.
