A maintenance management system for medical equipment is developed based on HIS.The system contains some special functions(including preventive maintenance,automatic job distribution,performance assessment,etc.)which are very useful for confirming the medical equipment in proper conditions and promoting the working efficiency of the staff.The system provides a technical support for the improvement of the maintenance management level.The CS/BS combined mode is adopted so that the maintenance is exempted at the users' end,and the data operation and statistical work become convenient at the engineering department's end.Furthermore,it provides a platform for future hospital information integration.

More and more DNA sequences have been obtained since the start-up of human genome project. Powerful system is badly needed for data mining on these DNA sequences. Based on a personal computer and Linux operating system, the Phred/Phrap/Consed software and Blast software were used to construct a platform for batch analysis of the sequences, including identifying raw DNA sequence from chromatogram file, vector sequence removing, contig analysis (sequence assembly), repeat sequence identifying and sequence similarity analysis. Result demonstrated that this robust platform could accelerate data analysis for large-scale DNA sequencing.
