Proton magnetic resonance spectroscopy (HMRS) is the only way to study noninvasively the metabolic and biochemical signature of the human tissues and organs.It can also quantify the metabolites within the volume of interest.The metabolic information about the lesions provided by the HMRS can greatly improve the diagnostic,grading accuracy,treatment planning such as target delineation and posttreatment follow-up of the glioma.

Objective To explore the application effect of weekly maintenance together for detection equipment by persons specifically designated.Methods Firstly carries on the preliminary training and the organization of the examination for all junior technicians and nurses,the appropriate persons were selected.Secondly,the recruited personnel were trained and as-sessed by the manufacturer or equipment engineers.After obtaining a certificate of conformity,weekly centralized mainte-nance for detection equipment officially began to implement in August 2014.Maintenance time was designated as every Wednesday afternoon or evening.Two months after the operation the test carried out by the head of clinical laboratory and the equipment department engineers in strict accordance with the week maintenance prcedures for each instrument and each item,and on-site questions.Other personnel also participated in the test as a control group.After half a year,the question-naire was sent to all the inspectors,and the satisfaction rate about the maintenance of the instrument was counted.Results Seven personnel selected to participate in the weekly maintenance,includings two senior technicians,three technicians and two nurses.Experimental personnel BC5390,UF-1000i,BH5100Plus and BH2100,C8000 and i2000,ADVIA2400 average score was significantly higher than the control group.Before and after the programme,the average number of failures of the instrument was reduced from 22 to 8 times and the average satisfaction rate of the inspection personnel was 83.0%±5.0%and 98.0%±2.0% respectively,and the difference was statistically significant.Conclusion Weekly centralized maintenance for detection equipment by persons specifically designated can truly implement instrument maintenance requirements,and at the same time with the implementation of the program,the failure times is greatly reduced,which is beneficial to improve the quality of inspection and to avoid the medical risks caused by TAT.

This paper discussed the existing problems of Information System ( LIS) from six aspects, inclu-ding:the security and the expansion of the function, protection of patients′privacy, the establishment of emergency response mechanisms, authenticity and accuracy of data and the risks for auto-approval rules, etc.The authors also analysed the necessity of its rectification from the perspective of ethics, proposed improvement programme and suggestions: strengthening the safety management systems and data, ensuring special check the confidentiality of the project, protect the patient′s privacy;setting up emergency mechanism;hospital based on the actual workload and resources to determine the LIS function module; regularly checking the test data, to avoid occupational inju-ries;continuously improving the rigour of automatic approval rules.
