Since January 2020, due to the epidemic of coronavirus disease 2019, all universities in China have postponed their studies or even suspend their studies. In response to the teaching policy of “suspending class, but keeping teaching and learning” , college teachers have rapidly changed into online teaching mode. However, how to ensure the quality and effect of online teaching still needs further exploration. Through analyzing the course characteristics of medical imaging diagnostics and students’ learning situations, this study discusses how to design detailed online teaching projects and improve the teaching quality and how to select online software suitable for the course. A questionnaire survey was conducted to evaluate the effect of online teaching during the spring course in 2020, selecting a total of 297 clinical and other undergraduate students of grade 2017 from West China School of Medicine of Sichuan University. The results showed that the detailed online teaching programs including “video learning” “distance teaching” “periodic examination” “weakness tutorial” were helpful to the learning process agreed by the majority of students. During the epidemic period, online teaching method can help students master the content of medical imaging diagnosis. In the era of Internet, the “online+offline” teaching mode is expected to be popularized in the future.
Objective To explore the Shanghai featured day surgery directory to provide policy support for further promoting the development of day surgery and focusing on appropriate diseases. Methods The data of day surgery patients discharged from Shanghai municipal hospitals within 24 hours between January 1 and September 30, 2021 or between January 1 and September 30, 2022 were collected. The number of day surgical cases, average cost and the trend of surgical diseases in 2021 and 2022 were compared. The day surgical diseases suitable for normalized epidemic prevention and control were summarized. Results A total of 35 municipal hospitals were included, including 175 201 patients. A total of 107 101 operations were performed in 2021 and 68 100 in 2022. In the second quarter of 2022, affected by the epidemic situation in Shanghai, the number of cases undergoing day surgery decreased significantly, and the average cost was not significantly affected by the epidemic situation. In 2022, 27 of the day surgery carried out in Shanghai municipal hospitals did not appear in the national recommended directory, and the number of operations for 6 diseases recovered rapidly under the normalized epidemic prevention and control. Conclusion Vigorously implementing day surgery can improve the utilization rate of hospital beds, speed up the turnover of patients, improve the utilization rate of medical resources, and reduce the hospitalization time of patients, the waiting time for surgery and the accompanying time of family members to meet the epidemic prevention requirements.
Objective To discuss the epidemiological characteristics of young and middle-aged people infected with COVID-19 in Gansu province under the new epidemic policy. Methods A total of 1800 people were collected from two tertiary hospitals in Gansu province from November 8, 2022 to January 28, 2023. The vaccination status, nucleic acid antigen detection, the specific time of infection, main symptoms and severity of the disease were investigated. Results Among 1800 participants, 1685 (93.6%) were vaccinated and 1565 (86.9%) were infected with COVID-19. Among the 1565 infected persons, 523 (33.4%) completed both nucleic acid and antigen testing, 382 (24.4%) completed nucleic acid testing, 490 (31.3%) completed antigen testing, 170 (10.9%) received IgG testing. 1490 (95.2%) were slight ill, 75 (4.8%) were critical ill, and 96 (6.1%) were hospitalized, and no one died. In 2022, 92 cases (5.9%) were infected in the first half of November, 141 cases (9.1%) in the second half of November, 630 cases (40.3%) in the first half of December, and 553 cases (35.4%) in the second half of December. 109 cases (7.0%) were infected in the first half of January, 38 cases (2.2%) in the second half of January, and 2 cases (0.1%) in the first half of February of 2023. and no cases in the second half of February. Among the 1565 infected persons, 825 (52.7%) had respiratory symptoms, 293 (18.7%) had gastrointestinal symptoms, 257 (16.4%) had autonomic disorders, 140 (8.9%) had other symptoms such as decreased smell and taste, and 48 (3.3%) had no symptoms after infection. Conclusions The vaccination rate of young and middle-aged people in Lanzhou city of Gansu Province is high. Since the new policy, the infection rate of the novel coronavirus among young and middle-aged people is high, the number of antigen tests is more than nucleic acid tests, most of the infected patients are slight, with fewer critical patients, and the hospitalization rate is low. The peak of infection occurred in early December 2022, and the infection rate was basically zero by February 2023. The main symptoms of COVID-19 infection are mainly respiratory tract, followed by digestive tract and autonomic nervous system disorders, and few patients are completely asymptomatic.
