Postmortem Diffusion of Aconitum Alkaloids and Their Metabolites in Rabbits.
Fa Yi Xue Za Zhi
April 2024
Objectives: To explore the postmortem diffusion rule of Aconitum alkaloids and their metabolites in poisoned rabbits, and to provide a reference for identifying the antemortem poisoning or postmortem poisoning of Aconitum alkaloids.
Methods: Twenty-four rabbits were sacrificed by tracheal clamps. After 1 hour, the rabbits were administered with aconitine LD in decocting aconite root powder by intragastric administration.
Detection of Carbamazepine and Its Metabolites in Blood Samples by LC-MS/MS.
Fa Yi Xue Za Zhi
February 2023
Article Synopsis
- A method was established to detect carbamazepine and its metabolites in blood using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
- Blood samples were extracted using a specific solvent and ultrasound, and were then analyzed using a gradient elution technique to separate the compounds.
- The method showed high sensitivity and selectivity, with strong linearity and accurate detection limits, making it effective for forensic identification of carbamazepine-related cases.
[Method for estimating relative chlorophyll content in wheat leaves based on chlorophyll fluorescence parameters].

Objective: To evaluate the necessity and suitability of the anti-HCV ELISA teot gray zone setted up by 7 blood station laboratories.
Methods: 7 blood station laboratories were coded as 1, 2, 3, 4, 5, 6 and 7 respectively; 8 kinds of ELISA reagents were coded as A, B, C, D, E, F, G and H respectively. 1 or 2 of 8 ELISA reagents produced by different manufactories were used to detect the anti-HCV in specimens of same group by 7 blood station laboratories; the Westen blot was used to detect the specimens with difference of detected results so as to difine the serological status of specimens.
Sinusoidal Signal Assisted Multivariate Empirical Mode Decomposition for Brain-Computer Interfaces.
IEEE J Biomed Health Inform
September 2018
Article Synopsis
- A brain-computer interface (BCI) lets users control devices using brain activity, typically measured by electroencephalography (EEG).
- Noise-assisted multivariate empirical mode decomposition (NA-MEMD) is a method used for analyzing EEG signals, but it introduces issues like redundant components due to white Gaussian noise.
- The study introduces a new method called sinusoidal assisted signal assisted MEMD (SA-MEMD), which improves performance by eliminating redundancy and enhancing classification accuracy for BCI applications.
The aim of the present study was to provide reliable experimental evidence for the application of autologous skin fibroblasts (asFbs) in the repair of depressed scars. In the experiments, depressed trauma was induced in male Wistar rats, and fibroblasts were separated from the removed skin tissues to culture in medium. cultured asFbs were injected into the depressed scar sites of rats, and the repair function of asFbs in the depressed scars was then examined at the cellular and whole-animal levels.
