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.

实体瘤对免疫治疗应答非常有限,因此,如何有效提升肿瘤免疫治疗的疗效,已成为当前肿瘤免疫治疗领域亟待解决的关键难题与挑战。髓系来源抑制性细胞（MDSCs）的趋化募集及其所介导的肿瘤免疫逃逸机制,是制约实体瘤免疫治疗效果的核心因素之一。文章深入探讨了MDSCs的起源、表型特征、其介导肿瘤免疫逃逸的具体机制,以及当前针对MDSCs的靶向治疗策略与将MDSCs靶向疗法与肿瘤免疫治疗相结合的最新研究进展。此外,文章还系统性地分析了靶向MDSCs联合免疫治疗策略所面临的关键挑战,并据此提出了MDSCs的精准靶向策略。这一策略旨在精确激活抗肿瘤免疫反应,为癌症患者提供更为个性化、高效的治疗方案,从而开启肿瘤免疫治疗领域的新纪元,为癌症治疗策略的创新与发展贡献力量。

Solid tumors exhibit a very limited response to immunotherapy．Consequently,effectively enhancing the therapeutic efficacy of tumor immunotherapy has emerged as a critical challenge and problem that urgently needs to be addressed in tumor immunotherapy．The chemotaxis and recruitment of myeloid-derived suppressor cells（MDSCs）and the tumor immune evasion mechanisms mediated by them are one of the core factors that significantly restrict the efficacy of immunotherapy for solid tumors．In this review,we discuss the origins and phenotypic characteristics of MDSCs,the specific mechanisms by which they mediate tumor immune evasion,as well as current targeted therapeutic strategies for MDSCs and the latest research progress in combining MDSC-targeted therapy with tumor immunotherapy．Furthermore,we have systematically analyzed the key challenges faced by the combination of MDSC-targeted and immunotherapy strategies,and accordingly proposed a precise targeting strategy for MDSCs．This strategy aims to precisely activate anti-tumor immune responses,providing more personalized and efficient treatment options for cancer patients,thereby opening a new era in tumor immunotherapy and contributing to the innovation and development of cancer treatment strategies．

长链非编码RNA（lncRNA）是一类长度大于200个核苷酸转录本,通过调控DNA、RNA及蛋白质的表达和功能,参与肿瘤发生、发展并发挥重要作用的RNA,近年来lncRNA成为恶性肿瘤早期诊断和预后标志物研究新的关注方向。Linc-UBC1作为一种新发现的lncRNA,在多种恶性肿瘤如肺癌、胃癌、结直肠癌、宫颈癌、卵巢癌、食管鳞癌等中异常高表达,可通过作为竞争性RNA（ceRNA）、参与信号通路等促进肿瘤细胞的增殖、迁移、侵袭、细胞周期进展、细胞凋亡和上皮间充质转化（EMT）等过程;高表达的linc-UBC1能够增加恶性肿瘤的耐药性,其表达水平与肿瘤分期、淋巴结转移和原发肿瘤远处转移呈正相关;linc-UBC1有望成为许多恶性肿瘤的新型的生物标志物、预后预测因子和治疗靶点,但其具体的调控机制仍处于研究的早期阶段,有待进一步深入研究。文章就目前linc-UBC1在恶性肿瘤发生和发展中的作用研究进展进行综述。

Long non-coding RNA（lncRNA）is a class of transcripts with a length of more than 200 nucleotides．It is involved in the occurrence and development of tumors and plays an important role by regulating the expression and function of DNA,RNA and protein．In recent years,lncRNA has become a new research direction for early diagnosis and prognosis of malignant tumors．As a newly discovered lncRNA,linc-UBC1 is abnormally highly expressed in a variety of malignant tumors such as lung cancer,gastric cancer,colorectal cancer,cervical cancer,ovarian cancer,and esophageal squamous cell carcinoma．It can promote the proliferation,migration,invasion,cell cycle progression,cell apoptosis and EMT of tumor cells by acting as a competing endogenous RNA（ceRNA）and participating in signaling pathways．High expression of linc-UBC1 can increase the drug resistance of malignant tumors,and its expression level is positively correlated with tumor stage,lymph node metastasis and distant metastasis of primary tumors．linc-UBC1 is expected to become a new biomarker,prognostic predictor and therapeutic target for many malignant tumors,while its specific regulatory mechanism is still in the early stage of research and needs further in-depth study．This article reviews the current research progress of linc-UBC1 in the occurrence and development of malignant tumors．

腺苷至肌苷RNA编辑（AIRE）是指转录前体RNA在腺苷酸脱氨酶的作用下,某些位点的腺苷发生脱氨反应转变成肌苷的过程,在碱基配对时,肌苷被识别作鸟苷,导致转录组重编写。随着高通量测序技术的不断进步,大量异常的AIRE被发现可导致氨基酸编码改变、RNA剪切异常以及microRNA-mRNA重定向等过程,从而参与肿瘤的发生发展。绝大部分的AIRE位点均位于基因非编码区,解析它们的生物学功能仍存在一定的挑战。本综述旨在描述AIRE的生物学机制和AIRE位点在不同肿瘤发生发展作用的进展,为AIRE与肿瘤的研究提供思路。

Adenosine-to-inosine RNA editing（AIRE）is catalysed by adenosine deaminases acting on RNA（ADARs）,which converts adenosine to inosine in nascent RNA．Since inosine is recognized as guanosine in post-transcriptional process,AIRE is functionally approximate to an A-to-G mutation and results in transcriptome recoding．With the continuous advancement of high-throughput sequencing technology,a large number of abnormal AIRE events have been found to exert different biological mechanisms such as amino acid changes,RNA splicing abnormalities and microRNA-mRNA redirection,which plays an important role in the development of human tumorigenesis．Most of AIRE sites are located in non-coding region,which brings challenges in analyzing their biological functions．This review aims to describe the biological mechanisms of AIRE and the relationship between AIRE sites and the development of different tumor types,providing ideas for the study of AIRE and tumors．

药物治疗抵抗在临床实践中成为肿瘤治疗失败的主因。最近的研究指出,肿瘤细胞的耐药性可能源于其内部高度的细胞异质性,而这种异质性的基础则是肿瘤可塑性。肿瘤细胞可塑性可能引发一系列反应,包括对治疗的耐药性发展、免疫系统逃逸以及对周围组织和血管系统的侵袭和转移等。本文简要介绍肿瘤细胞可塑性的表现形式以及其在药物治疗抵抗的非遗传适应性机制与靶向治疗新策略。

Drug therapy resistance has emerged as a primary cause of treatment failure in cancer management．Recent research indicates that the resistance of tumor cells may stem from their high degree of intracellular heterogeneity,with the underlying basis being tumor plasticity．Tumor cell plasticity can trigger a cascade of responses,including the development of resistance to treatment,evasion of the immune system,and invasion and metastasis into surrounding tissues and the vascular system．This article provides a brief overview of the manifestations of tumor cell plasticity and its non-genetic adaptive mechanisms in drug therapy resistance,along with novel strategies for targeted treatment．
