[摘要]目的：探讨纳米炭在分化型甲状腺癌（DTC）中不同注射时机下对患者术后低钙血症、甲状旁腺功能及中央区淋巴结清扫质量的影响，力求构建标准化操作路径。方法：将行甲状腺切除联合中央区清扫的DTC患者按1∶1∶1随机分为三组：术前超声引导注射组（POI）、术中直视注射组（IOI）及对照组（C）。比较三组术后48h校正血钙<2.1 mmol/L发生率、PTH水平、甲状旁腺误切率及淋巴结检出数，并以外渗评分、等待时间达标率评估操作规范性。结果：POI组术后低钙血症及甲状旁腺误切发生率最低，PTH水平下降幅度最小，中央区淋巴结及微小淋巴结检出数最多；IOI组次之；对照组最差。POI组外渗率为0，等待时间及分区送检一致性显著优于IOI组（均P<0.05）。三组均无严重并发症。结论：术前超声引导纳米炭注射能有效降低术后低钙风险，保护甲状旁腺功能，并提高清扫质量。结合过程指标构建的标准化路径，为临床推广提供了可复制的优选策略。

背景 虚拟标准化患者作为医学教育中的新型教学工具, 已广泛用于提升学生的临床问诊能力。随着生成式人工智能的快速发展, 基于大语言模型（LLMs）构建的VSP系统成为研究热点。然而, 目前尚缺乏对不同LLM在模拟患者角色方面表现的系统比较。目的 比较ChatGPT-4o与DeepSeek两种主流LLM在VSP模拟中的适用性, 评估其在病史采集、语言自然度、线索引导能力及教学辅助效果等方面的表现差异。方法 采用类实验研究,参与者为某医学院校临床医学专业本科四年级学生, 所有参与者均已修完《诊断学》课程, 具备基础问诊技能, 研究对象共60人, 按学号尾数单双分为两组, 分别与ChatGPT-4o或DeepSeek驱动的VSP系统进行交互。进行模拟急性阑尾炎问诊, 并在完成病史采集后提交诊断判断与体验问卷。结果 ChatGPT-4o在结构化信息整合、线索引导及技术稳定性方面更为优越, 而DeepSeek则在语言亲和力与情感回应方面表现更具人文关怀色彩。结论 不同LLM在VSP中的优势方向不同, 可根据教学目标进行有针对性地系统选择与设计。未来研究可进一步拓展至不同病种、交互方式及评估维度,以全面评估LLM驱动VSP在医学教育场景下的适应性与教学成效。

Background Virtual standardized patients（VSPs）have emerged as a novel tool in medical education, widely adopted to enhance students’ clinical interview skills．With the rapid development of generative artificial intelligence, VSP systems powered by large language models（LLMs）have become a new focus of research．However, few studies have systematically compared the performance of different LLMs in simulating patient roles．Objective This study aims to compare the applicability of two mainstream LLMs, ChatGPT-4o and DeepSeek, in VSP-based medical interview simulations, focusing on their differences in history-taking performance,linguistic naturalness, clue guidance,and educational support．Methods A quasi-experimental study was conducted involving 60 fourth-year clinical medicine undergraduates from a medical school．All participants had completed a diagnostics course and possessed basic interviewing skills．Students were assigned to either the ChatGPT-4o or DeepSeek group based on the parity of their student ID numbers．Each participant conducted a text-based simulated interview with a VSP presenting with acute appendicitis, then submitted both a preliminary diagnosis and a structured satisfaction questionnaire．Results ChatGPT-4o demonstrated superior performance in structured information integration, clue-based prompting, and system stability．In contrast, DeepSeek showed more natural language affinity and emotional responsiveness,reflecting stronger humanistic communication traits．The two models displayed divergent strengths within the VSP framework, suggesting that system selection and integration should be tailored to specific teaching objectives．Conclusions Future research should expand the scope to include diverse disease scenarios, interaction modalities, and evaluation dimensions, to comprehensively assess the educational utility and adaptability of LLM-driven VSP systems in medical training．

目的 粪菌移植(fecal microbiota transplantation,FMT)是治疗疾病的新途径,本文总结我院408例(1 085例次)FMT的临床疗效和安全性。FMT治疗艰难梭菌感染有效率达80%,抗生素相关性腹泻68%,炎症性肠病52%,功能性肠病65%,代谢性疾病50%,其他疾病57%,安全性良好,未见严重不良事件发生,结果和多数文献相符。还需更多随机对照试验才能明确FMT的临床价值。

目的 探讨标准化沟通模式在重症孕产妇院前转运前评估与交接环节中的应用效果。方法 设计转运前标准化沟通信息登记表,用以标准化转运前评估与交接环节,护士按照登记表中的项目逐条交接,对方未交代的项目护士进行主动评估,并将结果登记并汇报接诊医生。结果 运用标准化沟通模式后,有效缩短了转诊的通话时间和抵院后的处理时间,护士评估信息的错漏率由13.84%降低至4.23%,交接不清导致的不良事件发生率由7.41%降至1.21%,并在改善母婴结局等方面均取得较好效果。结论 SBAR 沟通模式在重症孕产妇孕前转运的评估和交接环节中保证了重要信息的准确传递,为重症孕产妇的救治争取宝贵时间,值得临床上推广应用。

Objective To explore the application effects of SBAR (situation, background, assessment and recommendation) communication mode in the transfer of critically ill obstetric women. Methods A transfer from based on SBAR communication mode was designed and used to assess the psychological status and illness condition of critically ill obstetric women. Results After the application of SBAR communication transfer model, the communication time and hospital action time were both shortened and the occurrence of transfer problems decreased,while the pregnancy outcomes were improved (P＜0.05). Conclusion Applying SBAR communication mode in the transfer of critically ill obstetric women is helpful to reduce the transfer time and the occurrence of transfer problems,and improve the quality of patient handover.

目的 探讨精神科急救培训用护士作为标准化病人的培养方法。方法 2013年9月挑选了4名精神科护士参加标准化病人系统培训,考核合格后成为护士标准化病人在2013年10月—11月对30名新护士自缢、噎食急救培训和考核中使用。结果 对急救培训中使用护士标准化病人,30名新护士中认为“新颖,第一次接触”19人(63%)、“满意”的26人(87%);4名作为标准化病人的护士都认为“非常有意义”。结论 精神科急救培训应用护士标准化病人丰富了培训的形式和内涵,得到了绝大部分参与人员的肯定。
