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.

目的 探讨导航护士主导的三级质控在胸腔镜肺癌切除术患者加速康复中的应用效果。方法 选取2020年6月—2023年6月周口市中心医院收治的106例肺癌患者,应用随机数字表法分为观察组（n=53）与对照组（n=53）。患者均采取胸腔镜肺癌切除术治疗,对照组实施常规的术前、术中及术后相关围术期护理,观察组在常规围术期护理基础上增加导航护士主导的三级质控护理。对比两组住院时间、术后并发症和护理前后世界卫生组织生活质量-100量表（WHOQOL-100）及癌因性疲乏程度（PFS）,最后对比两组的护理满意度。结果 观察组首次排气时间、首次下床时间、术后疼痛视觉模拟量表（VAS）评分、术后住院时间均优于对照组（P<0.05）;观察组并发症发生率低于对照组（P<0.05）;干预后两组WHOQOL-100评分升高、PFS评分降低,观察组均优于对照组（P<0.05）;观察组护理满意度高于对照组（P<0.05）。结论 对胸腔镜肺癌切除术患者,采取导航护士主导的三级质控管理的加速康复护理,可促进患者术后肠胃功能恢复,缩短住院时间,减轻术后疼痛感与减少并发症,在改善患者癌因性症状的同时,提升其生活质量,提高患者护理满意度。

Objective To explore the application effect of three-level quality control led by navigation nurses in accelerating rehabilitation of patients undergoing thoracoscopic lung cancer resection．Methods A total of 106 lung cancer patients admitted to our hospital from June 2020 to June 2023 were selected and randomly divided into an observation group（n=53）and a control group（n=53）using a random number table method．All patients were treated with thoracoscopic lung cancer resection,while the control group received routine preoperative,intraoperative and postoperative perioperative care,the observation group received a three-level quality control nursing led by navigation nurses in addition to routine perioperative care．The length of hospitalization,postoperative complications,WHOQOL-100 and PFS before and after care,and the nursing satisfaction of the two groups were compared．Results The observation group had significantly shorter first exhaust time,first time out of bed,postoperative visual analogue scale（VAS）score and postoperative hospital stay compared to the control group（P<0.05）．The incidence of complications in the observation group was lower than that in the control group（P<0.05）．After intervention,the WHOQOL-100 scores of both groups increased,and the observation group was higher than the control group．The PFS score decreased,and the observation group was lower than the control group（P<0.05）．The nursing satisfaction of the observation group was significantly higher than that of the control group（P<0.05）．Conclusions Adopting a three-level quality control management led by navigation nurses to accelerate rehabilitation care for patients undergoing thoracoscopic lung cancer resection can promote postoperative recovery of gastrointestinal function,reduce hospitalization time,reduce postoperative pain and complications,improve cancer related symptoms,improve their quality of life and increase patients nursing satisfaction．

目的 探讨超声弹性成像联合高频超声在甲状腺乳头状癌诊断中的应用价值。方法 2022年1月—2023年6月选择在中国人民解放军联勤保障部队第九九〇医院诊治的疑似甲状腺乳头状癌患者82例,所有患者均给予超声弹性成像联合高频超声检查,记录超声特征。所有患者均行病理检查,并以病理检查作为判断的金标准。结果 在82例患者中,病理诊断为甲状腺乳头状癌48例（癌性组）,占比58.54%;甲状腺良性结节34例（良性组）,占比41.46%。癌性组的形态异常、后方回声衰减、钙化、晕环征、边界不清晰、内部低回声等超声征象占比为81.25%、83.33%、83.33%、83.33%、81.25%、81.25%,高于良性组的52.94%、47.06%、47.06%、41.18%、47.06%、52.94%（P<0.05）。癌性组的收缩期最高流速低于良性组（P<0.05）,阻力指数、搏动指数与良性组相比有提高（P<0.05）。癌性组的弹性成像评分多为3~4分,良性组多为2分,两组比较差异有统计学意义（P<0.05）。超声弹性成像联合高频超声判断为甲状腺乳头状癌47例,诊断中的灵敏度与特异度分别为97.92%（47/48）和100.00%（34/34）。结论 甲状腺乳头状癌在超声上多表现为血流信号异常、钙化、后方回声衰减、晕环征等特征,超声弹性成像评分多为3~4分,超声弹性成像联合高频超声在其诊断中具有较高的应用价值。

Objective To explore the application value of ultrasound elastography combined with high-frequency ultrasound in the diagnosis of papillary thyroid cancer（PTC）．Methods From January 2022 to June 2023,82 patients with suspected PTC were treated at Chinese People’s Liberation Army Joint Logistics Force 990 Hospital．All patients were given ultrasound elastography combined with high-frequency ultrasound examination to record ultrasound features．All cases were given pathological examination,and the pathological examination were used as the gold standard for diagnosis．Results Among the 82 patients,48 were PTC（cancerous group）,accounting for 58.54%;and the other 34 were benign thyroid nodules（benign group）,accounting for 41.46%．The proportion of morphological abnormalities,posterior echo attenuation,calcification,halo ring signs,unclear boundary and internal hypoechoics in cancerous group were 81.25%,83.33%,83.33%,83.33%,81.25% and 81.25%,which were significantly higher than 52.94%,47.06%,47.06%,41.18%,47.06% and 52.94% in the benign group（P<0.05）．The highest systolic flow velocity in the cancerous group was significantly less than that in the benign group（P<0.05）,and the resistance index and pulse index were also significantly higher compared with the benign group（P<0.05）．The elastography score were mostly 3~4 in the cancerous group and 2 in the benign group,with a significant difference between the two groups（P<0.05）．Forty-seven cases of PTC were diagnosed by ultrasound elastography combined with high frequency ultrasonography,and the sensitivity and specificity in diagnosis were 97.92%（47/48）and 100.00%（34/34）,respectively．Conclusions PTC is often characterized by abnormal blood flow signals,calcification,posterior echo attenuation,halo sign and so on．The ultrasound elastography score is usually 3~4 points．Ultrasonic elastography combined with high frequency ultrasound has high value in diagnosis of PTC．
