Coronavirus disease 2019 (COVID-19) is an acute infectious respiratory disease. Ultrashort wave diathermy (USWD) for COVID-19 is recommended by some consensuses on COVID-19 rehabilitation diagnosis and treatment, while it is not mentioned in some other experts consensuses. Because the virus that causes COVID-19 is new and there are few related studies, this paper summarizes the research evidence and possible mechanisms of USWD in the treatment of viral pneumonia, and discusses the factors that need to be considered in the treatment of COVID-19. In this paper, it is suggested that before high-quality research evidence being obtained and under the condition of limited understanding of the pathogenesis and disease development of COVID-19, the application of USWD in COVID-19 should be cautious. To provide scientific and practical research evidence for the treatment of COVID-19 by USWD may be an urgent problem to be solved at present.
Objective To explore the shortcomings of the traditional clinical probation teaching mode, propose and implement the interactive teaching mode, so as to stimulate the students’ interest in knowledge and achieve better teaching effects. Methods The students of Grade 2017 who had clinical probation in the Orthopaedic Trauma Center of West China Hospital of Sichuan University from September 2020 to December 2021 were selected. Students were randomly divided into traditional clinical probation teaching mode group and interactive teaching mode group according to random number table method. Wechat mini program anonymous questionnaire survey was used to evaluate students’ satisfaction with the interactive teaching model of orthopaedic trauma and the teaching effect. Results A total of 110 students were enrolled, 55 in the traditional clinical probation teaching mode group and 55 in the interactive teaching mode group. There was no significant difference in gender or age between the two groups (P>0.05). The students in the interactive teaching mode group were better than those in the traditional clinical probation teaching mode group in orthopedic theory test (90.13±3.65 vs. 88.39±3.74; t=2.469, P=0.015) in the orthopedic theory test, teacher evaluation (89.15±2.94 vs. 87.56±3.12; t=2.751, P=0.007) and student self-evaluation (89.07±3.18 vs. 87.41±2.89; t=2.865, P=0.005). The teaching satisfaction of the interactive teaching group was higher than that of the traditional teaching group (96.36% vs. 87.27%; Z=?2.159, P=0.031). Conclusion Interactive teaching mode can effectively stimulate students’ interest in knowledge seeking, improve the enthusiasm and interaction of clinical probation, and effectively improve the satisfaction of undergraduate orthopaedic trauma clinical probation teaching.
At present, there has been no report in China that novel coronavirus specific immune globulin has been used to treat coronavirus disease 2019 (COVID-19). Recently, we had successfully treated one COVID-19 patient with intravenous injection of human immunoglobulin (COVID-19-IVIG). The female patient, aged 57 years, had clinical diagnosis: (1) COVID-19, common type; (2) postoperative colon cancer; (3) leukopenia; (4) low cellular immunity. 75 mL COVID-19 human immunoglobulin (Sinoptic Wuhan Blood Products Co., Ltd.) was intravenously injected twice. The patient was hospitalized for 49 days and had a good prognosis.
Most patients with coronavirus disease 2019 (COVID-19) have a good prognosis, but a certain proportion of the elderly and people with underlying diseases are still prone to develop into severe and critical COVID-19. Kidney is one of the common target organs of COVID-19. Acute kidney injury (AKI) is a common complication of severe COVID-19 patients, especially critical COVID-19 patients admitted to intensive care units. AKI associated with COVID-19 is also an independent risk factor for poor prognosis in patients. This article mainly focuses on the epidemiological data, possible pathogenesis, diagnostic criteria, and prevention and treatment based on the 5R principle of AKI associated with COVID-19. It summarizes the existing evidence to explore standardized management strategies for AKI associated with COVID-19.

Medical institutions, the last defense line for the medical treatment of coronavirus disease 2019, are crucial to avoid cross-infection in hospitals. And how to reasonably arrange patient visits and achieve early detection, early reporting, early isolation, and early treatment of patients with coronavirus disease 2019 and suspected cases at the same time is an important proposition. After the outbreak of coronavirus disease 2019, West China Hospital of Sichuan University continued to supplement and improve implementation details based on the three-level pre-examination and triage of infectious diseases, and established a three-level pre-inspection and triage management mechanism more suitable for coronavirus disease 2019, and successfully applied it. This article introduces the process and results of this outpatient three-level pre-examination and triage management optimization practice, aiming to provide an experience reference for the outpatient three-level pre-examination and triage in medical institutions.
ObjectiveTo explore the characteristics of chest high-resolution CT in common-type coronavirus disease 2019 patients.MethodsA retrospective analysis was performed on 35 patients in the Fever Clinic of West China Hospital of Sichuan University from January 21 to February 23, 2020. According to the nucleic acid test results, the patients were divided into a nucleic acid positive group of 14 cases, and a nucleic acid negative group of 21 cases. The clinical characteristics and high-resolution CT results (including lesion distribution, morphology, density, paving stone sign, air bronchial sign, vascular thickening sign, pleural effusion and enlarged lymph nodes, etc.) of the patients in each group were compared.ResultsThere was no statistically significant difference in the ratio of males to females, age distribution, clinical symptoms, or absolute lymphocyte values between the nucleic acid positive group and the nucleic acid negative group (P>0.05). The difference in epidemiological history between the two groups was statistically significant (P<0.05). The proportions of abnormal lymphocytes and white blood cell counts in the nucleic acid negative group were higher than those in the nucleic acid positive group (66.7% vs. 28.6%, P=0.041; 42.9% vs. 7.1%, P=0.028). The proportion of air bronchial signs in the nucleic acid negative group was higher than that in the nucleic acid positive group (47.6% vs. 7.1%, P=0.023). There was no significant difference in other high-resolution CT imaging findings between the two groups (P>0.05).ConclusionsCommon-type coronavirus disease 2019 patients have certain positive findings on chest high-resolution CT imagings. In clinical practice, high-resolution CT and other factors can be combined to assist in the diagnosis of coronavirus disease 2019.
