ObjectiveTo investigate the epidemiological characteristics of human brucellosis (hereinafter referred to as brucellosis) in Baoshan City, Yunnan Province, and to provide scientific evidence for adjusting prevention and control strategies. MethodsBased on the surveillance data of reported brucellosis cases in Baoshan City from 2020 to 2023 and the information collected through individual epidemiological questionnaire surveys, the epidemic status and clinical characteristics of brucellosis in Baoshan City were analyzed using descriptive epidemiological methods. ResultsA total of 85 brucellosis cases were reported in Baoshan City from 2020 to 2023, and detailed individual information was obtained for 83 of them. Brucellosis in Baoshan City showed a clear seasonal pattern, with peak incidence from May to September. The average annual incidence rate was 0.80/100 000, with a male-to-female ratio of 7.5∶1. And 82.35% of the cases aged 30 to 60 years, with farmers being the predominant affected group. The main clinical manifestations of the cases were myalgia and arthralgia. Regarding transmission routes, 87.95% of the cases had a contact history with cattle, with livestock rearing and grazing being the main exposure modes. Most infections occurred at home. ConclusionFrom 2020 to 2023, the incidence of brucellosis in Baoshan City exhibited a fluctuating upward trend, with a peak period from May to September. Males and farmers were identified as the primary affected populations. It is recommended to strengthen livestock surveillance and control, and to enhance both awareness and self-protection capacity among high-risk groups.

The experimental teaching of psychology is not only an important course in the undergraduate and graduate education of applied psychology, but also can assist the practical teaching of quite a few other subjects. It clearly divides three basic functions of experimental psychology teaching center: teaching, scientific research and service, which play an important role in facilitating teachers and students to understand corresponding courses. At the same time, it is discussed and proposed to strengthen the internal and external scientific linkage of the experimental center under the network background, and put forward the use of Internet technology, in order to improve the scientific use of the experimental teaching center, and reflect its maximum value, thereby achieving the purpose of university laboratory joint construction and serve the university to cultivate innovative and compound personnels.

Objective:To explore the application effect of BOPPPS teaching(bridge-in, objective, pre-assessment, participatory learning, post-assessment, summary) model based on comprehensive surgical nursing cases in higher vocational nursing students.Methods:The nursing students of three-year higher vocational nursing in a vocational college in Jiangsu province were involved in the study. Two classes were randomly selected and divided into observation group (54 students) and control group (53 students). Students in the observation group were taught with BOPPPS teaching model that required comprehensive case resources of surgical nursing, while students in the control group were taught with traditional case-based learning. At the end of the course, the differences of students' comprehensive assessment scores, learning feelings and teachers' teaching skills evaluation were compared between the two groups. SPSS 20.0 was used for t test. Results:The comprehensive curriculum assessment results of nursing students in the observation group were higher than those of the control group [(65.20±10.08) scores vs. (60.97±10.41) scores], with statistical significance in the differences ( t=2.141, P=0.035). The total learning feeling scores of the observation group was higher than those of the control group [(77.50±4.93) scores vs. (72.21±7.15)], with statistical significance in the differences ( t=4.45, P<0.001). The scores of teachers' introduction, demonstration, questioning, change, organization, strengthening and ending skills in the observation group were higher than those in the control group, with significant differences ( P<0.05). Conclusion:BOPPPS teaching model based on comprehensive surgical nursing cases can optimize teaching design, improve teaching effect, and promote learning and teaching interactively.
