This invention provides a detection model for allergic reactions to Qingkailing injection. The model comprises seven modules: a mouse ear blue staining area percentage testing and data storage module; a mouse ear blue staining area scoring module; a mouse ear blue staining area result judgment module; a mouse ear tissue Evans blue (EB) exudate quantitative testing and data storage module; a mouse ear tissue Evans blue exudate calculation module; a mouse ear tissue Evans blue exudate result judgment module; and a result output module. The model provides clear evaluation and analysis methods and result judgment criteria, exhibiting a high detection reaction rate. At a dosage of 10 ml / kg, the reaction rate of Qingkailing injection reaches 100%, and the EB exudate amount is 6-10 times that of the negative control group. Furthermore, the method is simple to operate, less time-consuming, and has good repeatability, accurately and truthfully reflecting whether Qingkailing injection causes allergic reactions. This model has significant value and importance for the quality control, process research, and clinical application safety of Qingkailing injection.

This invention discloses a method and system for assessing the risk of suicidal ideation in depressed patients based on a virtual high-altitude scenario. Subjects wear VR headsets, physiological monitoring devices, and eye-tracking glasses to record resting physiological data (I) and time deviation (I). In a "ground" scenario, a frame-and-bar test is performed, recording the error rate (ER_B). In the virtual high-altitude scenario, a high-altitude pain avoidance test and a time deviation test are performed at a certain height to establish a basis for assessing the subject's pain avoidance. At the maximum tolerable height, subjects perform a body balance test and a time deviation test, recording physiological data (II) and time deviation (III), and then perform the frame-and-bar test and time deviation test again, recording physiological data (III), time deviation (IV), and the error rate (ER_H). A basis for assessing the subject's fear of heights is established, and a risk level assessment of the subject's suicidal ideation risk is made. This invention objectively assesses the risk of suicidal ideation by observing the real performance of depressed patients in predicting effective factors for suicidal ideation.

The application discloses a method for adaptive weighted fusion based on multiple functional connection networks, and steps are as follows: pre-processing brain function image data output by a functional magnetic resonance instrument; dividing the pre-processed brain function image into a plurality of brain regions according to a standard template; calculating connection weights between each brain region based on multiple correlations, and respectively constructing functional connection networks; and adaptively learning and fusing weights for each functional connection network by using supervision information, so that a functional connection network containing multiple interaction information is obtained. The method has important theoretical significance and practical application value, and can fuse interaction information from different perspectives by using simple operation, can judge importance of each functional connection network in the fusion process, and integrates subsequent feature selection and classification into a model.
