目的 分析医院职业暴露工作人员特征、发生职业暴露环节、类型及处理方式,为医院制订干预措施提供理论基础。方法 回顾性分析玉溪市人民医院2018—2023年共301例发生职业暴露工作人员资料, 包括职业暴露时间、性别、年龄、科室、岗位类型、在院工作时间、职位、职业暴露发生环节、职业暴露类型、暴露源、职业暴露后是否需要用药等处置信息。结果 301例职业暴露工作人员平均年龄为（28.81±10.92）岁, 女性占比84.7%（255例）; 57.8%（174例）职业暴露发生在检查/穿刺/注射/采血/置管/治疗/手术等操作中, 38.9%（117例）发生在医疗废物处置环节;87.7%（264例）的暴露类型为针刺伤;45.5%（137例）接触暴露源为有血源性传播疾病的患者。发生职业暴露工作人员中, 不同岗位职业暴露者的暴露类型、职位、科室、是否需要药物干预及接触暴露源情况比较差异有统计学意义（P<0.05）。结论 应加强医务工作者职业暴露相关知识及应急处置培训, 对不同工龄、岗位医务工作者制定针对性培训方案, 加强医疗废物处置流程及临床操作技能规范等知识培训,预防医务工作者职业暴露的发生。

Objective To analyze the characteristics,occupational exposure links, types, and treatment methods of occupational exposure among healthcare staff hospital, providing a theoretical basis for the development of related intervention strategies for hospitals．Methods A retrospective study was conducted to explore 301 cases of occupational exposure among healthcare staff in The People’s Hospital of Yuxi City from 2018 to 2023．Data of 301 cases were collected, including information on gender, age,department,personnel category, length of service in the hospital, job title, and the circumstances of occupational exposures, which covered exposure links, type, source, and post-exposure medication treatment measures．Results Among the 301 healthcare staff experiencing occupational exposure, the average age was（28.81±10.92）years, with 84.7%（255 cases）being female．Occupational exposure most frequently occurred during procedures such as examination, puncture, injection, blood collection, catheterization, treatment, and surgery（57.8%,174 cases）, followed by the disposal of medical waste（38.9%, 117 cases）．The primary type of exposure was needle-stick injury（87.7%）．Contact with patients suffering from blood-borne infectious diseases accounted for 45.5%（137 cases）of the occupational exposure incidents．There were significant differences in exposure types, job positions, departments, sources of exposure, and post-exposure medication treatment measures among healthcare staff of different categories（P<0.05）．Conclusions To prevent the occurrence of occupational exposure among healthcare staff, it is necessary to enhance training on occupational exposure knowledge and emergency management, particularly improving the disposal of medical waste and clinical operational skills．Additionally, it is crucial to have personalized training programs tailored to healthcare staff based on their varying lengths of service and positions．

       目的  探讨转录因子E盒结合锌指蛋白1（ZEB1）、溶酶体相关膜蛋白5（LAMP5）在结直肠癌组织中的表达水平分析及预后预测价值。方法  选取驻马店市中心医院2018年1月—2020年1月收治的120例结直肠癌患者，分别采取所有患者的结直肠癌组织及癌旁组织进行免疫组化染色，对比ZEB1、LAMP5阳性率。对比不同病理特征结直肠癌患者ZEB1、LAMP5表达水平差异。对所有患者进行4年随访，依照随访结果将患者分为2个亚组，即预后不良组（n=35）和预后良好组（n=85），对比两组患者一般临床特征及ZEB1、LAMP5表达水平，应用Logistic回归分析ZEB1、LAMP5对结直肠癌预后的预测价值。结果 结直肠癌组织ZEB1、LAMP5相对表达量（38.26±5.49、26.77±3.85）与ZEB1、LAMP5阳性率（86.67%、72.22%）高于癌旁组织（15.46±2.54、8.04±1.59、23.33%、15.56%］，对比差异有统计学意义（t=41.280，χ²=25.437；t=49.255，χ ² =16.071；P＜0.05）。不同TNM分期［Ⅰ~Ⅱ期（35.55±4.13）、Ⅲ~Ⅳ期（42.32±4.75）］、淋巴结转移患者［是（44.37±4.28）、否（35.84±3.77）］、肿瘤分化程度［低分化（35.27±4.57）、中高分化（41.34±4.60）］ZEB1相对表达量对比差异有统计学意义（t=-8.281，P＜0.001；t=10.746，P＜0.001；t=-7.253，P＜0.001）；不同TNM分期［Ⅱ期（24.88±3.37）、Ⅲ~Ⅳ期（29.61±2.57）］、淋巴结转移［是（30.72±2.19）、否（25.21±3.19）］、肿瘤分化程度［低分化（24.57±3.62）、中高分化（29.04±2.55）］患者LAMP5相对表达量对比差异有统计学意义（t=-8.254，P＜0.001；t=9.227，P＜0.001；t=-7.797，P＜0.001）；预后良好组与预后不良组患者性别、年龄、大体类型、肿瘤大小对比差异无统计学意义（P＞0.05），预后良好组与预后不良组患者TNM分期、淋巴结转移、肿瘤分化程度、ZEB1、LAMP5阳性比例对比差异有统计学意义（P＜0.05）；Logistic回归分析显示：淋巴结转移、ZEB1阳性、LAMP5阳性为结直肠癌预后不良独立预测因素（P＜0.05）。结论  ZEB1、LAMP5在结直肠癌组织中呈现高表达状态，且与结直肠癌的发生有关，同时ZEB1、LAMP5是结直肠癌预后的独立预测因素，两者有希望成为结直肠癌的治疗靶点。
