During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objective:To explore the role of WeChat platform combined with flipped classroom in improving the working ability of resident doctors in the fever clinic.Methods:A total of 118 resident doctors who rotated in the fever clinic of department of emergency medicine were selected as the study subjects, and they were randomized into experimental group and control group, with 59 people in each group. The experimental group used WeChat platform and flipped classroom teaching, and the control group used traditional teaching. The results of theory assessment, operation performance and questionnaire survey were compared between the two groups. SPSS 26.0 statistical software was used for t test and chi-square test. Results:There was no significant difference in theoretical test scores between the experimental group and the control group ( P>0.05). The experimental group scored (91.61±3.01) points and the control group scored (84.52±4.02) points in operational assessment, with significant differences ( t=-10.85, P<0.05). The results of the satisfaction survey showed that there was no significant difference in teaching time distribution between the two groups, and the experimental group was better than the control group in any other aspects. Conclusion:The use of WeChat platform combined with flipped classroom during the COVID-19 epidemic can improve the level of operational skills of the resident doctors to wear or take off the protective clothing and collect nasopharyngeal swabs, help residents to avoid the infections, and improve the level of daily diagnosis and treatment of fever clinic.

Objective To investigate the diagnostic value of B-mode ultrasonography in detecting middle hepatic vein(MHV)in chronic liver disease patients.Methods 80 chronic liver disease patients were divided into 2 groups(chronic hepatitis and liver cirrhosis).Liver biopsies and the inner diameter(ID)of MHV was detected with B-mode ultrasonography.The ID of MHV was compared in the chronic hepatitis and liver cirrhosis groups,different liver fibrosis stages and compensation/non-compensation liver cirrhosis.The ability of ID of MHV in auxiliary diagnosis liver cirrhosis was analyzed with the receiver operating characteristic curve(ROC).Results The size of ID of MHV in liver cirrhosis(3.82±1.84)mm was smaller than that of chronic hepatitis(6.15±1.67)mm(P<0.01).The size of ID of MHV in non-compensation liver cirrhosis(2.98±1.15)mm was smaller than that of compensation liver cirrhosis(4.42±2 20)mm(P<0.05).There was midrange negative correlation with liver fibrosis stages and the ID of MHV(rs=-0.465,P<0.01).The cutoff point of ID of MHV diagnosis liver cirrhosis was 4.7mm.The area under ROC(AUC)achieved 0.813(P<0.01).The sensitivity(Se),specificity,(Sp),positive predictive value (PPV),negative predictive value(NPV)and Youden index were 67.5%,90.0%,88.0%,73.5% and 57.5%,respectively.Conclusion There is well clinical value with B-mode ultrasonography detecting ID of MHV for the auxiliary diagnosis of chronic liver disease.
