Interpretation of Guide to the Quality and Safety of Organs for Transplantation (6th edition): biosafety early warning / 器官移植

With the rapid development of organ donation and transplantation, it becomes increasingly important to improve the management system and ensure the quality and safety of organs for transplantation. Guide to the Quality and Safety of Organs for Transplantation (6th Edition) by European Committee provides the definitions of severe adverse reactions and severe adverse events in the perspective of biosafety early warning, delivers management and reporting processes, and encourages medical staff involved in organ transplantation to identify the adverse reactions and adverse events as soon as possible, and to carry out investigation, assessment and feedback. At the same time, it also systematically illustrates the warning and monitoring of organ transplantation risk, which is worthy of application in clinical study and practice.

Difference Analysis and Optimization Study for Determination of Fructose and Glucose by Near Infrared Spectroscopy / 分析化学

A total of 101 honey samples that originated from 20 different unifloral honey and other multifloral honey samples were collected from China.FT-NIR spectrometer were applied to determinate the content of fructose and glucose of honey with two different modes: transflectance (800-2500 nm, 2 mm optical path length) and transmittance (800-1370 nm, 20 mm optical path length).It was found that the prediction accuracy of fructose and glucose had significant difference with the two modes.In order to analyze the reason of this difference, support vector machine (SVM) was used to analyze the non-linear information, and genetic algorithm (GA) was used to analyze the characteristic wavelengths.The result indicated that the detection difference of fructose and glucose was originated from their different characteristic wavelengths.Through the optimization of detection method, it was found that for the determination of glucose, short wavelength and long optical path length should be used, on the other side, the whole wavelength region and short wavelength, with selecting the characteristic wavelength to avoid the disturb of water can also be used.For the determination of fructose, whole wavelength region and short optical path length should be used.Linear regression methods such as PLSR could obtain good results, and non-linear methods such as SVM did not improve the model performance.
