Abstract: A system for coma evaluation is provided, including: a stimulation-generating module operably affixed to a comatose patient for generating controllable stimulation signals to be applied to a target area on the comatose patient; a biosignal collecting module for acquiring a first EEG signal and a first EOG signal of the comatose patient in temporal association with the stimulation signals; and a processing module communicatively coupled to the biosignal collecting module, for separately processing the first EEG signal to obtain a stimulation EEG signal and a composite EOG signal; for processing the composite EOG, according to a second EOG signal measured without application of stimulation signals, to obtain an EOG signal relating to the induced eye-movement response of the comatose patient; and comprehensively processing the induced EOG signal and the stimulation EEG signal, so as to obtain a second EEG signal and evaluate coma severity of the comatose patient.

Abstract: The present disclosure provides a 3-phenoxybenzoic acid-glucuronic acid conjugate, and a preparation method and use thereof, and belongs to the technical field of pesticide detection. Compared with 3-phenoxybenzoic acid, the 3-phenoxybenzoic acid-glucuronic acid conjugate provided by the present disclosure features structural stability, high specificity, long limit of detection, and high content in urine, and can better serve as a marker that identifies whether an organism is killed due to pyrethroid pesticide poisoning. Namely, the 3-phenoxybenzoic acid-glucuronic acid conjugate can detect whether a toxicant (pyrethroid pesticides) is taken antemortem or exposed postmortem, and has an excellent application prospect in pyrethroid pesticide detection. The present disclosure provides a preparation method of a 3-phenoxybenzoic acid-glucuronic acid conjugate.

Abstract: A method for calculating drinking time includes: drawing a plurality of blood samples within 0 to 120 h upon start of drinking, testing concentrations of alcohol, EtG and EtS in the blood samples, and obtaining an average concentration ratio CEtG/CEtS; obtaining a quadratic regression equation by fitting using the average concentration ratio CEtG/CEtS as an abscissa and sampling time as an ordinate; and measuring CEtG/CEtS of blood samples under test, obtaining a relationship between the drinking time and the CEtG/CEtS based on the quadratic regression equation, and calculating the drinking time.
