RESUMO
Introductory paragraphThe pandemic of coronavirus Disease 2019 (COVID-19) caused enormous loss of life globally. 1-3 Case identification is critical. The reference method is using real-time reverse transcription PCR (rRT-PCR) assays, with limitations that may curb its prompt large-scale application. COVID-19 manifests with chest computed tomography (CT) abnormalities, some even before the onset of symptoms. We tested the hypothesis that application of deep learning (DL) to the 3D CT images could help identify COVID-19 infections. Using the data from 920 COVID-19 and 1,073 non-COVID-19 pneumonia patients, we developed a modified DenseNet-264 model, COVIDNet, to classify CT images to either class. When tested on an independent set of 233 COVID-19 and 289 non-COVID-19 patients. COVIDNet achieved an accuracy rate of 94.3% and an area under the curve (AUC) of 0.98. Application of DL to CT images may improve both the efficiency and capacity of case detection and long-term surveillance.
RESUMO
OBJECTIVE:To discuss the dispensing of prescriptions of traditional Chinese medicine.METHODS:According to the dispensing procedure of Chinese traditional medicine and the principle of drug use,the problems occurred during Chinese traditional medicine dispensing were pointed out and analyzed.RESULTS:The problems occurred in the dispensing of prescriptions of traditional Chinese medicine were mainly resulted from doctors,pharmacists and nurses' lack of basic rationale or they had no intimate knowledge of operation regulations.These problems can be avoided if with efforts.CONCLUSION:Only through strictly following the prescription of Chinese traditional medicine can the quality and efficacy of Chinese drugs dispensing be guaranteed.
RESUMO
Objective To discuss the issues encountered in fee charging,mainly the automatic recognition of charging agent.Methods Based on No.1 Military Medical Project,the present status of fee charging in the hospital was analyzed.The single disease payment system and charging system adapting to all kinds of medical insurance policies were designed,whose payment decomposition flow was introduced.Results The payment decomposition flow,compatible with all medical payment regulations in China,was applied in the outpatient department charging system of General Hospital of PLA.Conclusion The payment decomposition flow,is gifted with universal validity for complicated charging conditions in China.
