为探究梅花鹿源肺炎克雷伯氏菌有效的防控和治疗方法，分别采集动物园内呼吸困难的梅花鹿（Cervus nippon）的咽拭子，以及死亡梅花鹿的肺脏、心血、肝脏等病料组织76份，采用细菌分离鉴定和PCR方法进行肺炎克雷伯菌（Klebsiella pneumoniae）分离鉴定，采用人工感染动物性试验、K-B药敏纸片法分别检测其致病性和耐药性。结果显示：从采集的76份病料组织样品分离得到52株肺炎克雷伯菌，其中40株对小白鼠具有致病性。分离的40株致病性肺炎克雷伯菌对阿莫西林、氨苄西林、庆大霉素等9种药物耐药率在70.0%以上，对其他药物的耐药率为7.5%~27.5%。

回顾了昆明动物园20年滇金丝猴圈养历程,总结了人工条件下滇金丝猴饲养、繁育、疾病防治的经验及教训,对进一步的保护工作提出思考,认为应充分发挥专业性动物园的保护教育职能,才能促进社会和谐发展,并建议林业部门协调异地保护以支持就地保护。

Medical Immunology is a core basic course for medical majors. In order to broaden students' horizons, cultivate students' scientific thinking, and improve students' problem-solving ability, we designed the "scientific problem-based discussionsituational teaching" module in Medical Immunology course. We create "scientific research situations" based on "cutting-edge topics" to allow students investigating in the laboratory just like scientific researchers. The course includes three parts: "Problem-Lecture-Discussion", "Teaching by Expert" and "Experiment Observation", allowing students to experience the research processes, including how to propose, analyze and solve the scientific questions. This teaching method effectively promotes students' understanding and application of theoretical knowledge, increases their team spirit, cultivates their scientific thinking, and stimulates their interests in scientific research.

The construction of first-class courses and the implementation of curriculum ideological and political education are two problems faced by higher education. Taking the national first-class course animal physiology of Southwest University as an example, combined with the construction background of the "New Agricultural Science", this paper introduces how professional teachers and ideological and political teachers can achieve the same direction and form a "educating community", how to excavate the ideological and political elements of the course on the basis of "two properties and one degree", and how to integrate the ideological and political elements of the course into the teaching practice through innovating the teaching mode and compiling the curriculum ideological and political cases of the course. We share the experience of how to combine the examination of the ideological and political effect of the course with the examination of knowledge, and put forward some views and suggestions on the problems that need to be further solved in the current curriculum ideological and political construction. The aim is to better integrate the construction of first-class courses with the implementation of curriculum ideological and political education, and cultivate more new talents of "knowing and loving agriculture" for the construction of "New Agricultural Science".

Objective To understand the incidence and characteristics of new cases of pneumoconiosis in Wuxi from 2012 to 2021. Methods In July 2022, all the data of new cases of pneumoconiosis in Wuxi reported by employers from 2012 to 2021 in the "Occupational Disease and Health Hazard Monitoring Information System" were selected for descriptive analysis of their basic situation, age at diagnosis and dust exposure time, diagnosis time and trend, region, industry, enterprise type, and economic scale. Results A total of 1 444 cases of occupational pneumoconiosis were reported in Wuxi from 2012 to 2021, including 1 274 males (88.23%) and 170 females (11.77%); the average age at diagnosis was (54.35 ± 12.31) years old, and the average dust exposure time was (13.23 ± 7.12) years; the age at diagnosis was mostly between 40-49 years old (453 cases, accounting for 31.37%), and the exposure time was mostly between 10-20 years (729 cases, accounting for 50.48%); silicosis (799 cases, accounting for 55.33%) and welding fume pneumoconiosis (480 cases, accounting for 33.24%) were the main types of diseases; in terms of stage distribution, stage I accounted for 77.08% (1 113 cases), stage Ⅱ accounted for 14.96% (216 cases), and stage Ⅲ accounted for 7.96% (115 cases); in terms of regional distribution, Jiangyin City ranked first with 507 cases (35.11%), followed by Xishan District with 490 cases (33.93%) and Yixing City with 275 cases (19.04%); new cases of pneumoconiosis were mainly concentrated in manufacturing (969 cases, accounting for 67.11%) and mining industries (431 cases, accounting for 29.85%), with private enterprises (740 cases, accounting for 51.35%) and collective enterprises (552 cases, accounting for 38.23%) as the main types of enterprises; small enterprises accounted for 73.55% (1 062/1 444), and medium-sized enterprises accounted for 9.14% (132/1 444). Conclusions Silicosis and welding fume pneumoconiosis were the main types of new pneumoconiosis cases in Wuxi City. New cases showed obvious regional, industrial, and disease distribution differences, and occupational health supervision should be strengthened for small and medium-sized private enterprises in the manufacturing and mining industries.
