目的了解成都市某区人类免疫缺陷病毒感染/艾滋病(HIV/AIDS)男性青年学生病例确诊前性行为和AIDS知识获取情况,为制定青年学生AIDS防治措施提供参考依据。方法对2021年1月—2023年12月招募的25名成都市某区新报告的HIV/AIDS男性青年学生进行定性访谈,调查内容包括AIDS感染相关高危行为、知识获取途径及感染后心理状况等。结果所有访谈者均发生过同性性行为,首次同性性行为平均年龄为(17.48±1.64)岁。从首次性行为到确诊的时长,最短为0年,最长为8年,平均为(2.72±1.41)年。所访谈者安全套使用率均较低,仅2人表示“每次都用”,且12人确诊前从未进行过HIV检测。所有访谈对象均知晓AIDS相关知识,但对风险的认知度较低,其中16人认为自己不会被感染,8人知晓有风险但存在侥幸心理,1人不知道这些知识的作用。学校和网络是主要的知识获取途径,其中3人通过微博、抖音、知乎等网络平台了解,9人通过学校的讲座、主题班会等获取知识,13人通过学校和网络了解过相关知识;所有访谈对象均未从家庭教育中获取过AIDS相关知识。在知道自己患病后,21人存在沮丧、抑郁、悲观、绝望等负面情绪(7人表示焦虑和抑郁,9人感到恐惧和害怕,5人感到悔恨),仅4人态度较为坦然。结论首次性行为年龄较小、多性伴、网络交友普遍以及AIDS知行分离是HIV/AIDS男性青年学生感染的重要原因。需制定有针对性的防治措施,遏制AIDS在青年学生中的传播。

作者：张飞虎李琛 ZHAO Hang leng bing REN Lele School of Mechatronics Engineering Harbin Institute of Technology

The elastic-plastic transition regime and brittle-ductile transition regime in scratch process for optical glass BK7 were analyzed based on the Hertzian equation and the stress ratio theory which was proposed by Wei. The interacting scratch process for optical glass BK7 with the grit interval distance as the variable was simulated by the ABAQUS software of finite element simulation based on the energy fracture theory. Double grits interacting scratch test for optical glass BK7 was carried out on the DMG ULTRASONIC 70-5 linear, by which the reliability of finite element simulation was verified. The surface morphology of the workpiece was analyzed by scanning electron microscopy（SEM）, which showed that the width of groove increased obviously with the increase of scratch depth and the grit interval distance. Results of the width of groove were consistent with the simulation results. The subsurface damage layer was analyzed by the method of HF acid etching, which showed that there was an area of cracks intersecting. The scratching force was measured by the threedimensional dynamometer of KISTLER, which showed that the second scratching force increased with the increase of scratching depth and the grit interval distance. The force in the second scratch was smaller than that in the first time, which was consistent with the Griffith fracture theory.

肥胖是一种复杂的慢性疾病,随着生活水平的提高,全球和中国超重和肥胖的人数越来越多。肥胖可以引发一系列健康问题,如心血管疾病、2型糖尿病、卒中,甚至肿瘤及社会心理疾病。目前治疗肥胖的方式包括饮食与运动,以及在此基础上的药物治疗和手术治疗。已上市的减重药物如芬特明/托吡酯、纳曲酮/安非他酮、氯卡色林、奥利司他等因各种严重不良反应限制了其临床使用,胰高血糖素样肽-1受体激动剂(glucagon-like peptide-1 receptor agonists,GLP-1RAs)因减重效果优异且安全性好而备受关注。该文就美国食品药品监督管理局已批准减重适应证的GLP-1RA类药物利拉鲁肽和司美格鲁肽及国内外在研GLP-1RA类减重药物的疗效和安全性,以及GLP-1RA类减重药在我国的批准使用情况进行综述,以期为广大医务工作者提供参考。
