Study Of Surpporting Information System For Use Mass Spectrometry Rapid Screening Toxic Substances In Emergency Food Poisoning Incident

Background:Although the development of science and technology today has reached a considerable level, but in ensuring food safety issues, both developing and developed countries are facing severe challenges. Sudden unexplained cases of food poisoning causing the community and individuals a great harm, but recognize the cause of poisoning is important to deal with such incidents。Therefore, the development a "unknown toxicological screening test supporting information platform"-"Supporting information system for use Mass Spectrometry rapid screening toxic substances in emergency food poisoning incident ", is a meaningful practice of concept for rapid screening system for poison under the conditions in ChinaObjective:Development a Supporting information system for use Mass Spectrometry rapid screening toxic substances in emergency food poisoning incident, using for supporting confirm the causes of poisoning, in order to reduction of adverse effects of food poisoning incidents in the community.Methods:According to the new characteristics of today's treatment of food poisoning, information systems developed in this paper completed the following work.Study the emergency information system status which related to food poisoning event at home and abroad, analysis the features of those systems.Understanding the principles of mass data production,storage, and on this basis, study the new mass compare algorithm to improve the accuracy of judging the unknown poison。Filtering and sorting out the most common toxic materials can cause food poisoning. And to classify them, design a proper poison information storage logical framework, and collecting the necessary information.Learn computer information technology, database platform technology, chemical informatics and other disciplines related to this project, using those technology to complete the construction of the platform.Entry the toxicological data into the system, finally the availability of the information platform was confirmed to ensure that project can play its expected functions.Result:Initially completed the hardware and software structure of "Surpporting information system for use Mass Spectrometry rapid screening toxic substances in emergency food poisoning incident" and nearly one hundred of poison's information was entered, the user can searching various kinds of toxic substance information by different searching conditions. System providing the function of search toxic substance by mass spectrum of toxic species, and the function of searching the toxic substance by toxic symptom. At the same time the system can also provide laboratory testing methods for toxic substance, and emergency rescue procedures and other information for toxic substance.
