目的   调查南宁市2022—2024年食源性疾病的发生情况，并分析该地食源性疾病的流行病学特征，为防控食源性疾病提供依据。方法   在2022年1月—2024年12月统计南宁市多中心上报的食源性疾病发生情况，并分析食源性疾病的分布特征。结果  2022年1月—2024年12月在南宁市共计调查21 712例食源性疾病患者，其中男性占49.25%，女性占50.75%；食源性疾病以18～59岁、4～17岁年龄段占比相对较高，在季节方面2022年以秋季占比较高，2023—2024年以夏季占比较高；散居儿童、学生和农民是食源性疾病的主要人群，混合食品、水果及其制品、粮食类及其制品、肉类及其制品为前四位暴露食品；包装方面以散装占比最高、进食场所则以家庭占比最高；食源性疾病患者3年间不同性别、年龄段、发病季节、人群类型、暴露食品、包装形式及进食场所比较差异均有统计学意义（P＜0.05）。症状主要以消化道症状、其他/全身症状为主。结论   南宁市2022—2024年食源性疾病发生例数有所增长，多发于夏秋季节，散居儿童、学生、农民是食源性疾病的高风险群体，同时针对散装食品，尤其混合食品、水果及其制品、粮食类及其制品、肉类及其制品等主要暴露食品应做好重点防控监测，可根据本地食源性疾病发生的流行病学特征进行对应的宣传教育，以确保食品安全。

       Objective  To explore the occurrence of foodborne diseases in Nanning City from 2022 to 2024，and analyze the epidemiological characteristics of foodborne diseases in the area，providing a basis for the prevention and control of foodborne diseases．Methods  From January 2022 to December 2024，the incidence of foodborne diseases reported by multiple centers in Nanning City was statistically analyzed，and the distribution characteristics of foodborne diseases were analyzed．Results  From January 2022 to December 2024，a total of 21 712 foodborne disease patients were analyzed in Nanning City，among them，males account for 49.25% and females account for 50.75%．Foodborne diseases had a relatively high proportion in the age groups of 18-59 and 4-17 years old．In terms of seasons，the proportion was higher in autumn 2022 and in summer 2023-2024．Scattered children，students，and farmers were the main populations of foodborne diseases，with mixed foods，fruits and their products，grains and their products，and meat and its products being the top four exposed foods．In terms of packaging，bulk packaging had the highest proportion，while in terms of eating places，household packaging has the highest proportion．There were statistically significant differences in the gender，age group，onset season，population type，exposed food，packaging form，and eating location of foodborne disease patients over a three-year period．Conclusions  The number of foodborne diseases in Nanning City has increased from 2022 to 2024，mostly occurring in summer and autumn seasons．Scattered children，students，and farmers are high-risk groups for foodborne diseases．At the same time，key prevention and control monitoring should be carried out for bulk foods，especially mixed foods，fruits and their products，grains and their products，meat and their products，and corresponding publicity and education can be carried out according to the epidemiological characteristics of local foodborne diseases to ensure food safety．

      近视是一种常见的屈光不正状态，也是全球范围内普遍存在的视觉健康问题，其特征是在眼部调节放松的状态下，平行光线经眼的屈光系统折射后聚焦在视网膜前，导致视远模糊。近视通常在儿童期发生和发展，但在成年期仍可继续发生和发展。本综述对已发表的关于成年人近视发生和进展的文献进行总结，描述成年人近视的流行病学特征，包括近视率、近视发病率、近视进展率及其近视特征（屈光度及眼轴），总结成年人近视发病和进展的危险因素。了解成年人近视的发展特点和管理方式对于近视防控实践具有重要意义。

   Myopia is a common refractive error and a universal visual health problem in the world. It is characterized by the fact that parallel light rays refract through the refractive system of the eye and focus in front of the retina when the eye accommodatior is relaxed, resulting in distant blurred vision. Myopia usually occurs and develops in childhood, but can continue to occur and develop in adulthood. This review summarizes the published literature on the occurrence and progression of myopia in adults, describes the epidemiological characteristics of myopia in adults, including myopia rate, myopia incidence rate, myopia progression rate, and myopia characteristics（diopter and ocular axis） ; and summarizes the  risk factors for the occurrence and progression of myopia in adults. Understanding the developmental characteristics and management methods of adult myopia is of great significance for myopia prevention and control practice.
