    C-X-C基序趋化因子受体4(CXCR4)是乳腺癌的有希望的治疗靶标,因为它在包括三阴性乳腺癌(TNBC)在内的所有乳腺癌分子亚型的细胞表面上过表达。在这里,CXCR4拮抗肽-NaGdF4纳米点缀合物(称为抗CXCR4-NaGdF4NDs)已通过将C-X-C基序趋化因子12(CXCL12)衍生的环肽与胰蛋白胨包被的NaGdF4纳米点(直径5±0.5nm,称为Try-NaGdF4ND)。制备的抗CXCR4-NaGdF4ND表现出高纵向弛豫率(r1)值(21.87mM-1S-1),合理的生物相容性和良好的肿瘤积累能力。抗CXCR4-NaGdF4NDs的特征提高了肿瘤MRI敏感性,并促进了体内小鼠携带MDA-MB-231肿瘤模型注射后的肿瘤生物治疗。使用抗CXCR4-NaGdF4ND的MRI引导的生物治疗能够抑制46%的肿瘤生长。此外,在注射后24小时,在小鼠尿液中发现约47%注射剂量的抗CXCR4-NaGdF4ND。这些发现表明,抗CXCR4-NaGdF4NDs可以用作肾脏可清除的纳米药物,用于乳腺癌的生物治疗和MRI。
    C-X-C motif chemokine receptor 4 (CXCR4) is a promising therapeutic target of breast cancer because it is overexpressed on cell surface of all molecular subtypes of breast cancer including triplenegative breast cancer (TNBC). Herein, CXCR4 antagonistic peptide-NaGdF4 nanodot conjugates (termed as anti-CXCR4-NaGdF4 NDs) have been constructed for magnetic resonance imaging (MRI)-guided biotherapy of TNBC through conjugation of the C-X-C Motif Chemokine 12 (CXCL12)-derived cyclic peptide with tryptone coated NaGdF4 nanodots (5 ± 0.5 nm in diameter, termed as Try-NaGdF4 NDs). The as-prepared anti-CXCR4-NaGdF4 NDs exhibits high longitudinal relaxivity (r1) value (21.87 mM-1S-1), reasonable biocompatibility and good tumor accumulation ability. The features of anti-CXCR4-NaGdF4 NDs improve the tumor-MRI sensitivity and facilitate tumor biotherapy after injection in mouse-bearing MDA-MB-231 tumor model in vivo. MRI-guided biotherapy using anti-CXCR4-NaGdF4 NDs enables to suppress 46% tumor growth. In addition, about 47% injection dose of anti-CXCR4-NaGdF4 NDs is found in the mouse urine at 24 h post-injection. These findings demonstrate that anti-CXCR4-NaGdF4 NDs enable to be used as renal clearable nanomedicine for biotherapy and MRI of breast cancer.

    近几十年来,对微生物组稳态与宿主健康之间相互作用的不断研究,在描述疾病发病机理的分子机制和开发新的治疗策略方面拓宽了新的领域。通过运输蛋白质,核酸,脂质,以及其多功能生物活性分子中的代谢物,细胞外囊泡(EV),天然生物活性细胞分泌的纳米颗粒,可能是微生物群-宿主通信的关键介质。除了在不同的生理和病理过程中发挥积极和消极的作用外,有大量证据表明细菌分泌的电动汽车(细菌电动汽车[BEVs])参与各种疾病的发生和发展,包括胃肠,呼吸,皮肤病学,神经学,肌肉骨骼疾病,以及癌症。此外,越来越多的研究探索基于BEV的平台来设计新颖的生物医学诊断和治疗策略.因此,在这次审查中,我们强调BEV生物发生的最新进展,composition,生物功能,以及它们在疾病病理中的潜在参与。此外,我们介绍了BEV在诊断分析中的当前和新兴临床应用,疫苗设计,和新的治疗发展。
    In recent decades, accumulating research on the interactions between microbiome homeostasis and host health has broadened new frontiers in delineating the molecular mechanisms of disease pathogenesis and developing novel therapeutic strategies. By transporting proteins, nucleic acids, lipids, and metabolites in their versatile bioactive molecules, extracellular vesicles (EVs), natural bioactive cell-secreted nanoparticles, may be key mediators of microbiota-host communications. In addition to their positive and negative roles in diverse physiological and pathological processes, there is considerable evidence to implicate EVs secreted by bacteria (bacterial EVs [BEVs]) in the onset and progression of various diseases, including gastrointestinal, respiratory, dermatological, neurological, and musculoskeletal diseases, as well as in cancer. Moreover, an increasing number of studies have explored BEV-based platforms to design novel biomedical diagnostic and therapeutic strategies. Hence, in this review, we highlight the recent advances in BEV biogenesis, composition, biofunctions, and their potential involvement in disease pathologies. Furthermore, we introduce the current and emerging clinical applications of BEVs in diagnostic analytics, vaccine design, and novel therapeutic development.

    干燥综合征(SS)是一种以干燥综合征为主要表现的全身性自身免疫病理学,强烈的无力和关节肌痛。也可能出现系统性表现。自2019年以来,免疫抑制剂(IS)或生物疗法仅推荐用于全身受累的患者。然而,在2019年之前,在某些情况下,无症状的患者接受了IS/生物疗法治疗,通常是标签外的。目的:我们建议评估在无全身受累的SS患者中使用IS/生物疗法的益处和安全性。方法:我们回顾性收集了1980年1月至2023年10月在格勒诺布尔大学医院(法国)根据ACR/EULAR诊断标准诊断的所有SS患者的临床记录。结果:包括83例患者:64例最初为非全身形式。在这些最初为非全身形式的患者中,24例采用IS/生物疗法治疗。他们都没有发展二级系统化,而未经治疗组的40例患者中有11例(p<0.05)。另一方面,IS/生物疗法似乎不能改善干燥综合征。无严重不良事件发生。结论:早期引入IS/生物疗法治疗似乎为患者提供了益处,而没有副作用。
    Sjögren\'s syndrome (SS) is a systemic autoimmune pathology manifested mainly by a dry syndrome, intense asthenia and arthromyalgia. Systemic manifestations may also occur. Since 2019, immunosuppressant agents (IS) or biotherapies are recommended only for patients with systemic involvement. However, before 2019, in some cases, paucisymptomatic patients had been treated with IS/biotherapies, often off-label. Objective: We propose to evaluate the benefit and safety of using IS/biotherapy in patients with SS without systemic involvement. Methods: We retrospectively collected the clinical records of all patients with SS diagnosed according to ACR/EULAR diagnostic criteria followed up between January 1980 and October 2023 at Grenoble University Hospital (France). Results: Eighty-three patients were included: 64 with an initially non-systemic form. Of these patients with an initially non-systemic form, 24 were treated with IS/biotherapy. None of them developed secondary systematization, whereas 11 out of 40 patients in the untreated group did (p < 0.05). On the other hand, IS/biotherapy did not appear to improve dry syndrome. There were no serious adverse events. Conclusion: Early introduction of an IS/biotherapy treatment appears to provide a benefit for the patient without side effects.

    背景:富血小板血浆(PRP),含有血小板和生长因子的血液产品,用于治疗许多非止血疾病。研究已经探索了使用PRP来提供快速修复,愈合,和从各种损伤中恢复;一些研究提到与使用透明质酸等其他形式的治疗相比,PRP的有效性。商用PRP系统现在可用,每个人都各不相同,这取决于它是如何准备的,从而引起血小板浓度和生长因子含量的变化。这些变化还涉及不同的治疗应用。
    方法:本文回顾了PRP的各种应用,包括使用PRP治疗前要考虑的因素,并提供了广泛的PRP应用程序列表。
    结果:将PRP作为独立治疗或联合治疗给药可观察到阳性结果。然而,PRP制备缺乏标准化,增加结果中异质性和偏见的风险。
    结论:使用PRP确实是再生治疗的一种选择,但在完全将其推荐为主要治疗方式之前,还需要更多的研究。
    Platelet-rich plasma (PRP), a blood-based product containing platelets and growth factors, is being utilized to treat numerous non-hemostatic disorders. Studies have explored the use of PRP to provide rapid repair, healing, and recovery from various injuries; some studies mentioned the effectiveness of PRP as compared with other forms of treatment like the use of hyaluronic acid. Commercially available PRP systems are available now, and each varies from one another depending on how it is prepared, thus causing variations in platelet concentration and growth factor content. These variations also implicated different therapeutic applications.
    The paper reviews the various applications of PRP, including factors to consider before using PRP therapy, and provides an extensive list of PRP applications.
    The administration of PRP as a standalone treatment or as a co-therapy results in observed positive outcomes. However, there is a lack of standardization for PRP preparation, increasing the risks for heterogeneity and bias amongst results.
    The use of PRP is indeed an option for regenerative therapy, but more research is needed before it can fully be recommended as a primary treatment modality.

    分析单个机构的头颈部粘膜黑色素瘤(MMHN)的治疗结果和预后因素。
    从1989年12月至2018年11月,纳入了190例诊断为MMHN的患者。使用Kaplan-Meier方法进行生存分析,用于单变量分析,其中对显著性进行对数秩检验,对多变量分析进行Cox回归。
    中位随访时间为43.5个月,126例(68.5%)患者死亡。平均DSS为35个月。3年和5年疾病特异性生存率(DSS)分别为48.1%和33.7%,分别。中位总生存期(OS)为34个月。3年和5年OS率分别为47.0%和32.9%,分别。在单变量分析中,T3阶段,接受了手术,R0切除,联合治疗(手术+生物治疗/生物化疗)与更好的生存率显著相关。多变量Cox回归分析显示T4分期(HR=1.692;95%CI,1.175-2.438;p=.005)和N1分期(HR=1.600;95%CI,1.023-2.504;p=.039)是低生存率的强预后因素,联合治疗(手术+生物治疗/生物化疗)是较好生存结局的重要预后因素(HR=0.563;95%CI,0.354-0.896;p=0.015).
    MMHN的预后仍然较差。有必要进行系统治疗以减少MMHN进展。手术结合生物治疗可以提高生存率。
    UNASSIGNED: To analyze the treatment outcomes and prognostic factors of mucosal melanoma of the head and neck (MMHN) from a single institution.
    UNASSIGNED: From December 1989 to November 2018, 190 patients diagnosed with MMHN were included. Survival analysis was performed using the Kaplan-Meier method for univariate analysis with a log-rank test for significance and Cox regression for multivariate analysis.
    UNASSIGNED: With a median follow-up time of 43.5 months, 126 (68.5%) patients died. The median DSS was 35 months. The 3- and 5-year disease-specific survival (DSS) rates were 48.1% and 33.7%, respectively. The median overall survival (OS) was 34 months. The 3- and 5-year OS rates were 47.0% and 32.9%, respectively. In univariate analysis, the T3 stage, received surgery, R0 resection, and combined therapy (surgery+biotherapy/biochemotherapy) were significantly associated with better survival. Multivariable Cox regression analysis revealed that the T4 stage (HR = 1.692; 95% CI, 1.175-2.438; p = .005) and the N1 stage (HR = 1.600; 95% CI, 1.023-2.504; p = .039) were strong prognostic factors for poor survival, and that combined therapy (surgery+biotherapy/biochemotherapy) was a strong prognostic factor for better survival outcome (HR = 0.563; 95% CI, 0.354-0.896; p = .015).
    UNASSIGNED: The prognosis of MMHN remains poor. Systemic treatment is warranted to reduce MMHN progression. Surgery combined with biotherapy may improve survival.

    Magnetic ferrite nanoparticles (MFNPs) have great application potential in biomedical fields such as magnetic resonance imaging, targeted drugs, magnetothermal therapy and gene delivery. MFNPs can migrate under the action of a magnetic field and target specific cells or tissues. However, to apply MFNPs to organisms, further modifications on the surface of MFNPs are required. In this paper, the common modification methods of MFNPs are reviewed, their applications in medical fields such as bioimaging, medical detection, and biotherapy are summarized, and the future application directions of MFNPs are further prospected.

    肠道微生物群是一个复杂的生态系统,与人体共进化了数亿年。在过去的30年里,随着基因测序和组学技术的进步,尤其是在消化系统疾病和系统代谢性疾病领域,与肠道菌群相关的研究发展迅速。机械,生物,免疫,等因素使肠道菌群与肝胆形成密切的双向联系,这可以称为“肠-肝-胆轴”。“肝脏和胆囊,作为腹膜的内脏器官,患有阴险的发作,不容易被发现。诊断通常通过实验室化学检查和成像方法进行,通常仅在发生器质性病变时才采取干预措施。此时,有些人可能已经进入了疾病发展的不可逆转阶段。我们回顾了在过去3-5年中描述肠道菌群在肝胆疾病的发病机制和生物治疗中的作用的文献。包括疾病不同阶段肠道菌群的动态变化,以及涉及肠道菌群及其代谢产物的信号通路,等。在总结上述内容后,我们希望强调肠道菌群作为早期预防的新临床目标的潜力,早期诊断,肝胆疾病的及时治疗和预后。图形摘要。
    The gut microbiota is a complex ecosystem that has coevolved with the human body for hundreds of millions of years. In the past 30 years, with the progress of gene sequencing and omics technology, the research related to gut microbiota has developed rapidly especially in the field of digestive system diseases and systemic metabolic diseases. Mechanical, biological, immune, and other factors make the intestinal flora form a close bidirectional connection with the liver and gallbladder, which can be called the \"gut-liver-biliary axis.\" Liver and gallbladder, as internal organs of the peritoneum, suffer from insidious onset, which are not easy to detect. The diagnosis is often made through laboratory chemical tests and imaging methods, and intervention measures are usually taken only when organic lesions have occurred. At this time, some people may have entered the irreversible stage of disease development. We reviewed the literature describing the role of intestinal flora in the pathogenesis and biotherapy of hepatobiliary diseases in the past 3-5 years, including the dynamic changes of intestinal flora at different stages of the disease, as well as the signaling pathways involved in intestinal flora and its metabolites, etc. After summarizing the above contents, we hope to highlight the potential of intestinal flora as a new clinical target for early prevention, early diagnosis, timely treatment and prognosis of hepatobiliary diseases.

    Ovarian cancer (OC) is a common gynecologic malignancy with poor prognosis and high mortality. Changes in the OC microenvironment are closely related to the genesis, invasion, metastasis, recurrence, and drug-resistance. The OC microenvironment is regulated by Interferons (IFNs) known as a type of important cytokines. IFNs have a bidirectional regulation for OC cells growth and survival. Meanwhile, IFNs positively regulate the recruitment, differentiation and activation of immune cells. This review summarizes the secretion and the role of IFNs. In particular, we mainly elucidate the actions played by IFNs in various types of therapy. IFNs assist radiotherapy, targeted therapy, immunotherapy and biotherapy for OC, except for some IFN pathways that may cause chemo-resistance. In addition, we present some advances in OC treatment with the help of IFN pathways. IFNs have the ability to powerfully modulate the tumor microenvironment and can potentially provide new combination strategies for OC treatment.
