ObjectiveAn input system was designed to solve the current problems of slow creation of electronic health record caused by the difficulty of resident information input.MethodsThe system,based on the Android platform,was designed to collect and save information by using PDA devices,and to send the information to the remote receiver over the wireless network with the hybrid encryption of DES and RSA.The receiver saved the information into the relational database after decryption.ResultsThe system saved acquisition time greatly compared to the traditional method.The transmission speed,security and reception rate of the system could well satisfy the requirements of information collection.ConclusionThe system provides a better way to solving the problems of heavy workload,low efficiency and high error rate in information collection,and will play an important role in practical life.

A kind of saliva glucose detector based on electrochemistry is designed to measure the saliva glucose of diabetes mellitus, so as to achieve non-invasive measurement for diabetes mellitus state. A Prussian blue modified glassy carbon electrode was designed as the working electrode of the three-electrode system to improve the electrode sensitivity to H2O2's electrochemical reaction in a lower voltage. A three-electrode system was employed for measuring the current generated by the oxidation-reduction reaction of glucose catalyzed by glucose oxidase. Technique of shield-driving was used to avoid the attenuation of the voltage when it was processed, so as to ensure the precision measurement. A single chip microcomputer, C8051F020, was used to control the system and provide scanning voltage for the electrode, make A/D transition and process the result. Then the outputs were displayed on liquid crystal display. This detector's operating voltage was 0.496 V. The sensitivity was 0.1 mmol/L. There was a constant of proportionality between the measuring results of this detector and the precise analysator, Lanbiao LK98B. Results of the study show that this detector has low operating voltage, high sensitivity and good function of whole system, and can meet the request of measure.

Objective According to the lack of timeliness in the current domestic disease notification system,an effective solution is proposed to solve the problem.Methods Based on research and analysis of the health information exchange standards HL7 (Health Level 7),which is widely used in the world,a solution on the base of HL7 standards is proposed in this study,to store,transfer,analyze and publish data.Results The solution allows medical institutions and the centers for disease control connect seamlessly,ensuring the data transfer in time,and publishing the data through Web service.Conclusion The solution can keep the people abreast of the latest status of the epidemic,and do their own protection as well as promote social stability.
