    Autosomal dominant polycystic kidney disease（ADPKD）stands as a leading cause of inherited renal failure，with current therapeutic strategies lacking effective means to reverse disease progression．Stem cell therapy，owing to its potential in tissue repair and immunomodulation，has emerged as a focal point of research．This review systematically elucidates the mechanisms by which hematopoietic stem cells（HSCs）intervene in ADPKD pathology through paracrine effects，metabolic reprogramming，and immune regulation．Furthermore，it summarizes clinical translational evidence of HSCs in both acute kidney injury and chronic kidney disease．This article also comparatively analyzes the unique advantages and challenges of mesenchymal stem cells（MSCs）and induced pluripotent stem cells（iPSCs）in the context of ADPKD treatment，thereby providing theoretical support for the development of multimodal stem cell therapies．

       乳腺癌（BC）发病率持续上升，已成为严重威胁公共健康的重大挑战，转移仍是导致患者死亡的主要原因。目前，切除肿瘤并辅以放化疗后仍有较大几率发生转移。此外，早期转移隐匿性强，干预措施不完善及耐药发生迅速均是预后不良的重要因素。细胞外囊泡（EVs）是由细胞释放的、具有膜结构的纳米级颗粒，是细胞间通讯的重要介质。EVs通过转运膜性组分、胞质蛋白及核酸等，调控乳腺癌的发生、进展及转移定植，其来源异质性决定了其在乳腺癌转移中发挥独特作用。本文重点总结了不同来源EVs作为液体活检标志物在转移预警中的价值，以及靶向EVs分泌或阻断其通讯网络在克服免疫治疗耐药中的潜在临床应用，以期为临床医生提供有价值的诊疗参考。

     The incidence of breast cancer（BC） continues to rise and has become a major public health challenge．Metastasis remains the principal cause of BC-related mortality．Currently，there remains a high probability of metastasis even after surgical tumor resection followed by radiotherapy and chemotherapy．The insidious nature of early metastasis，inadequate intervention strategies，and rapid development of drug resistance are all critical factors contributing to poor prognosis．Extracellular vesicles（EVs） are membrane-enclosed，nanoscale particles released by cells．As mediators of intercellular communication，EVs transfer membrane components，cytosolic proteins，and nucleic acids to recipient cells，thereby modulating BC initiation，progression，and metastatic dissemination．The heterogeneity of EV origins determines their distinct roles in breast cancer metastasis．This review focuses on summarizing the value of EVs from different sources as liquid biopsy biomarkers for metastasis warning，as well as their potential clinical applications in targeting EV secretion or blocking their communication networks to overcome immunotherapy resistance，aiming to provide valuable diagnostic and therapeutic references for clinicians．

       目的 探索Nrf2/HO-1通路是否参与远志皂苷元（远志）在脑出血体外细胞模型中对BV2小胶质细胞炎症反应的调控作用。方法 采用红细胞与BV2小鼠小胶质细胞共培养构建体外脑出血模型。分别给予远志单独处理、远志联合Nrf2抑制剂ML385处理，检测炎症因子水平。收集细胞上清制备条件培养基，用于培养SH-SY5Y人神经母细胞瘤细胞，并检测其铁死亡水平。结果 模型组BV2细胞炎症因子（IL-1β，IL-6，TNF-α）水平较对照组显著升高（P＜0.001）；高浓度远志（20 μM）可降低炎症因子水平，并上调Nrf2/HO-1通路蛋白表达，而ML385能逆转该作用。模型组条件培养基可诱导SH-SY5Y细胞铁死亡，而经远志处理的BV2细胞条件培养基则减轻该现象；ML385预处理可削弱远志对SH-SY5Y细胞的保护作用，远志组铁离子、丙二醛、转铁蛋白受体1水平低于远志联合ML385组（P＜0.05），铁转运蛋白、谷胱甘肽和谷胱甘肽过氧化物酶水平高于远志联合ML385组（P＜0.05）。结论 远志皂苷元通过激活Nrf2/HO-1通路抑制BV2小胶质细胞炎症反应，并在脑出血体外模型中发挥神经保护作用。

     Objective To investigate whether the Nrf2/HO1 signaling pathway is involved in the regulatory effect of tenuigenin（TEN）on the inflammatory response of BV2 microglial cells in an in vitro intracerebral hemorrhage（ICH）model．Methods An in vitro ICH model was established by coculturing BV2 murine microglial cells with red blood cells．Cells were treated with TEN alone or in combination with the Nrf2 inhibitor ML385，and the levels of inflammatory factors were measured．The conditioned medium collected from the cell supernatant was used to culture SHSY5Y human neuroblastoma cells，and ferroptosis levels were assessed．Results The levels of inflammatory factors（IL-1β，IL-6，TNF-α）in BV2 cells of the model group were significantly higher than those in the control group（P＜0.001）．High concentration of TEN（20 μM）could reduce the levels of inflammatory factors and up-regulate the expression of Nrf2/HO-1 pathway proteins，while ML385 could reverse this effect．The conditioned medium of the model group could induce ferroptosis in SH-SY5Y cells，while the conditioned medium of BV2 cells treated with TEN could alleviate this phenomenon．Pretreatment with ML385 could weaken the protective effect of TEN on SH-SY5Y cells．The levels of iron ions，malondialdehyde and transferrin receptor protein 1 in the TEN group were lower than those in the TEN combined with ML385 group（P＜0.05），while the levels of ferroportin glutathione and glutathione peroxidase 4 were higher than those in the TEN combined with ML385 group（P＜0.05）．Conclusions TEN inhibits the inflammatory response of BV2 microglial cells by activating the Nrf2/HO1 pathway and exerts a neuroprotective effect in the in vitro ICH model．

新生儿期的免疫系统发育阶段对维持新生儿健康至关重要,具有独特的免疫调节机制。近年来,人们越来越关注髓源性抑制细胞（MDSCs）在新生儿免疫调节中的作用。MDSCs是一类免疫抑制功能强大的异质性细胞群体,它们能够通过多种机制调节免疫应答。MDSCs在新生儿中的调节作用对防止过度免疫反应和促进免疫耐受至关重要,有助于预防新生儿期炎症性疾病,并对其后续健康产生积极影响。近期研究文献分析展示了MDSCs在新生儿免疫调节中的多种作用机制,包括在特定病理条件下的保护作用、与新生儿期炎症反应的相互作用,以及对长期免疫发展的潜在影响。因此,深入理解MDSCs在新生儿免疫中的角色,不仅有助于揭示其复杂的调节机制,也为制定新的预防和治疗新生儿炎症性疾病的策略提供了新的思路。

The developmental stage of the immune system during the neonatal period is crucial for maintaining neonatal health,characterized by unique immunoregulatory mechanisms．In recent years,increasing attention has been drawn to the role of myeloid-derived suppressor cells（MDSCs）in neonatal immune regulation．MDSCs represents a heterogeneous population of cells with potent immunosuppressive functions,capable of modulating immune responses through various mechanisms．The regulatory role of MDSCs in neonates is vital for preventing excessive immune reactions and promoting immune tolerance,thereby aiding in the prevention of neonatal inflammatory diseases and positively influencing subsequent health outcomes．Analysis of recent research literature reveals multiple mechanisms through which MDSCs contribute to neonatal immune regulation,including protective effects under specific pathological conditions,interactions with neonatal inflammatory responses,and potential impacts on long-term immune development．Therefore,a comprehensive understanding of the role of MDSCs in neonatal immunity not only helps elucidate their intricate regulatory mechanisms but also provides novel insights for developing strategies for the prevention and treatment of neonatal inflammatory diseases．
