Objective To explore the mechanism of competitive binding of non coding long stranded RNA ANRIL（lncRNA-ANRIL）to miR-181b to mediate phosphatase and tensin homolog gene（PTEN）on myocardial injury in coronary heart disease．Methods Thirty patients diagnosed with coronary heart disease in our hospital from October 2023 to June 2024 were included as the observation group,and another 30 individuals from physical examination center during the same period were selected as the control group．Blood pressure indicators,blood lipid indicators, and serum levels of lncRNA-ANRIL, miR-181b, and PTEN were measured in the two groups of patients, and the test results were compared．Results There was no significant difference between the two groups in terms of gender, age, BMI, smoking and hypertension（P>0.05）．The levels of systolic blood pressure（SBP）, diastolic blood pressure（DBP）, total cholesterol（TC）, triglycerides（TG）, and low-density lipoprotein cholesterol（LDL-C） in the observation group were higher than those in the control group,while high-density lipoprotein cholesterol（HDL-C） was lower than that in the control group（P<0.05）．The relative expression levels of lncRNA-ANRIL Exon 1-2, Exon 17-18, and PTEN levels in the observation group were lower than those in the control group（t=12.623, 7.741, 8.231, P=0.001）, while the level of miR-181b was higher than that in the control group（t=37.250, P=0.001）．Conclusions Compared with healthy individuals, serum levels of lncRNA-ANRIL and PTEN are significantly reduced in patients with coronary heart disease, while miR-181b levels are elevated, indicating that lncRNA ANRIL can regulate PTEN expression by miR-181b, thereby affecting the process of myocardial injury in coronary heart disease．

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．

自发性脑出血由于外伤性原因引起脑实质出血作为神经系统急危重症,该患病率约占所有脑卒中的10%~15%, 具有高患病率、高死亡率、高致残率的特点, 随着年龄的不断增长血管逐渐变薄、失去弹性,受到外在原因干扰时, 导致出血, 形成血肿, 依据血肿的不同程度, 患者的生存及预后有着显著的差异。因此快速且及时识别自发性脑出血尤为重要,可为临床医生评估患者病情变化及预后具有重要指导的意义, 然而在临床实践过程中对于快速识别脑出血的方法有所欠缺, 需要进一步优化其监测方法。因此本文综述了自发性脑出血的监测方法, 探讨通过无创监测、有创监测及联合监测自发性脑出血为临床快速高效判断脑出血提供科学的依据和参考。

近年来, 药物递送系统在肿瘤靶向治疗领域取得了显著进展, 已有多种递药系统获批临床应用。其中, 纳米药物因其能够减少传统小分子化疗药物的毒副作用、提高药物生物利用度,并通过增强通透性与滞留效应（EPR效应）实现肿瘤的被动靶向, 从而显著提升治疗效果, 受到广泛关注。尤其是具备尺寸可调、肿瘤特异性聚集、刺激响应性崩解及形貌转变等多功能的智能可变形纳米载体, 已成为当前纳米递药载体研究的热点。这类载体能够感应肿瘤微环境中的特定刺激信号（如酸性pH值、过氧化还原状态、酶活性或过表达细胞因子）, 实现包括尺寸调控、聚集组装、结构崩解与形态重构等在内的多种动态变形行为, 从而提升药物在肿瘤部位的滞留时间、渗透深度及控释能力, 最终获得更优的抗肿瘤疗效。例如在肿瘤组织中实现纳米载体尺寸缩小可增强药物的组织穿透力; 纳米粒子聚集变大会延长药物在病灶处的滞留时间; 而快速响应性崩解则有助于药物在肿瘤局部实现高效释放。这些智能变形策略为纳米药物递送系统提供了更高的治疗可控性与精准性。基于其多样化的响应特性和结构可塑性, 智能变形纳米载体在推动抗肿瘤药物的个体化治疗及联合疗法应用方面展现出巨大潜力。本文综述了近年来基于智能变形纳米载体增强抗肿瘤效果的研究进展,系统梳理了其设计策略, 并深入探讨了其在肿瘤精准治疗中的应用前景。

In recent years, drug delivery systems have made remarkable progress in the field of tumor-targeted therapy, with several platforms already approved for clinical use．Among them, nanomedicines have attracted considerable attention due to their ability to mitigate the side effects of conventional small-molecule chemotherapeutics, improve bioavailability, and passively accumulate at tumor sites via the enhanced permeability and retention（EPR）effect, thereby enhancing therapeutic efficacy．Of particular interest are stimuli-responsive, shape-transformable nanocarriers, which exhibit unique properties such as tunable size, tumor-specific accumulation, and structural adaptability in response to tumor-associated cues．These intelligent deformable nanocarriers are capable of undergoing various dynamic transformations—including aggregation, disassembly, size modulation, and morphological transitions—triggered by specific stimuli in the tumor microenvironment（TME）, such as pH, redox potential,enzymes,or cytokines．Such transformations enhance drug retention at tumor sites, improve intratumoral penetration, and enable spatiotemporally controlled drug release, ultimately resulting in superior antitumor efficacy．For instance, nanosystems that shrink in size at tumor sites can promote deeper tissue penetration, while those that aggregate into larger assemblies can prolong local drug retention．Conversely, carriers that disassemble rapidly under tumor-specific stimuli allow for burst release of the encapsulated payload precisely at the disease site．These adaptive features hold great promise for improving the therapeutic performance of nanomedicines. Furthermore, the multifunctionality of intelligent deformable nanocarriers supports the development of personalized treatment regimens and combination therapies, offering novel strategies for cancer management．This review highlights recent advances in the design and application of shape-transformable nanocarriers for enhanced anticancer drug delivery, summarizing design principles and exploring their emerging potential in precision oncology.
