    中枢神经系统肿瘤是脑和脊髓内神经元细胞的异常增殖。它们可以是主要的,也可以是次要的,并放置沉重的财务,心理,和个人的身体负担。高选择性血脑屏障,只允许特定分子流入脑实质,抑制药物的功效。治疗方案包括手术,放化疗,和靶向治疗。尽管治疗在过去几十年取得了进展,总体发病率和死亡率仍然很高,强调需要改进治疗选择,以进一步提高生存率和生活质量。纳米药物在使用微观粒子增强生物利用度和选择性的体内试验中已经证明了令人鼓舞的结果。迄今为止最成功的临床结果是脂质体,细胞外囊泡,和仿生纳米粒子;尽管如此,需要进行临床试验以确认其安全性,功效,负担能力,长期影响,以及来自各种人口统计学的患者的成功。纳米药物有可能改变脑肿瘤的治疗模式,允许更好的结果作为主要和辅助治疗。
    Central nervous system tumors are abnormal proliferations of neuronal cells within the brain and spinal cord. They can be primary or secondary and place a heavy financial, psychological, and physical burden on individuals. The highly selective blood-brain barrier, which only permits specific molecules to flow into the brain parenchyma, inhibits the efficacy of pharmacological medicines. Treatment options include surgery, chemoradiotherapy, and targeted therapy. Despite advances in therapy over the past few decades, the overall morbidity and mortality rates are still high, emphasizing the need for improved therapeutic choices to improve survival and quality of life further. Nano pharmaceuticals have demonstrated encouraging outcomes in in vivo trials using microscopic particles to enhance bioavailability and selectivity. The most successful clinical results to date have been achieved by liposomes, extracellular vesicles, and biomimetic nanoparticles; nevertheless, clinical trials are required to confirm their safety, efficacy, affordability, longterm impact, and success in patients from various demographics. Nano pharmaceuticals have the potential to change the paradigm of therapy for brain tumors, allowing better outcomes as primary and adjunctive therapy.

    三阴性乳腺癌(TNBC)是最致命的类型之一,占所有乳腺癌的20%。化疗是进展的TNBC治疗的传统方式;然而,它具有高可逆性步伐的短期结果。对于患有TNBC的患者,缺乏靶向治疗有限且依赖人的治疗选择,这警告说这是乳腺癌患者中最严重的癌症类型。因此,这种疾病的适当治疗被认为是一项重大的临床挑战.因此,已经开发了各种治疗方法来治疗TNBC,其中化疗是最近研究的最常见和众所周知的方法。虽然有效的方法是化疗,它们往往伴随着严重的限制,特别是缺乏特定的功能。这些方法会导致系统毒性,最终,多药耐药(MDR)癌细胞的扩增。因此,寻找新颖有效的技术来增强TNBC治疗的靶向性是必不可少的。脂质体已经证明它们是一种有效的药物递送方法;然而,在每年开发的大量基于脂质体的药物递送系统中,少数刚刚获得临床应用授权。使用脂质体的新方法用各种配体靶向其结构以提高治疗效率并减少对各种身体组织的不期望的副作用。目前的研究描述了在临床前和临床阶段与用不同配体作为靶向药物载体功能化脂质体结构相关的最新策略和研究。
    Triple-negative breast Cancer (TNBC) is one of the deadliest types, making up about 20% of all breast cancers. Chemotherapy is the traditional manner of progressed TNBC treatment; however, it has a short-term result with a high reversibility pace. The lack of targeted treatment limited and person-dependent treatment options for those suffering from TNBC cautions to be the worst type of cancer among breast cancer patients. Consequently, appropriate treatment for this disease is considered a major clinical challenge. Therefore, various treatment methods have been developed to treat TNBC, among which chemotherapy is the most common and well-known approach recently studied. Although effective methods are chemotherapies, they are often accompanied by critical limitations, especially the lack of specific functionality. These methods lead to systematic toxicity and, ultimately, the expansion of multidrug-resistant (MDR) cancer cells. Therefore, finding novel and efficient techniques to enhance the targeting of TNBC treatment is an essential requirement. Liposomes have demonstrated that they are an effective method for drug delivery; however, among a large number of liposome-based drug delivery systems annually developed, a small number have just received authorization for clinical application. The new approaches to using liposomes target their structure with various ligands to increase therapeutic efficiency and diminish undesired side effects on various body tissues. The current study describes the most recent strategies and research associated with functionalizing the liposomes\' structure with different ligands as targeted drug carriers in treating TNBCs in preclinical and clinical stages.

    存在许多生产脂质体的技术;然而,这些方法需要修改,因为它们无法实现脂质体尺寸和均匀性的精确管理,以及它们对试剂和资源的低效利用。一个特别的挑战在于复制在生物细胞中看到的准确的形式和大小控制,通过宏观方法实现这一精度水平证明异常艰巨。微流控技术的出现通过将脂质体合成降低到厘米级芯片来解决这个问题,大幅削减相关成本,并提高脂质体的制造效率和流动性。尽管已经建立了用于微米或纳米颗粒制备的各种微流体技术,制造微流体装置由于其高成本和耗时的性质而带来挑战。然而,一个有希望和成本效益的解决方案在于添加剂生产,通常由3D打印指导。这种创新技术已显示出巨大的潜力,并已成功应用于制造微流体芯片。这里,我们将探索使用3D打印来生产专门为脂质体生产设计的微流体设备。此外,将充分讨论由3D打印制造的芯片生产的脂质体的生物医学应用。
    Numerous techniques exist for the production of liposomes; however, these methods need to be revised due to their incapacity to achieve precise management of the dimensions and uniformity of liposomes and their inefficient utilization of reagents and resources. One particular challenge lies in replicating accurate form and size control seen in biological cells, as accomplishing this level of precision through macroscale approaches proves exceptionally arduous. The advent of microfluidic technology tackles this problem by lowering liposome synthesis to a centimeter-level chip, drastically cutting related costs, and enhancing liposome manufacturing efficiency and mobility. Although various microfluidic technologies for micro or nanoparticle preparation have been established, manufacturing microfluidic devices poses challenges due to their high cost and time-consuming nature. However, a promising and cost-effective solution lies in additive production, commonly guided by 3D printing. This innovative technique has demonstrated significant potential and has been successfully applied to create microfluidic chips. Here, we will explore using 3D printing to produce microfluidic devices specifically designed for liposome production. Moreover, the biomedical applications of the liposomes produced by 3D printing-fabricated chips will be fully discussed.

    有限数量的研究直接检查了脂质体包封的植物化学物质的作用及其在成人中的抗肥胖作用。本研究旨在总结脂质体包裹的植物化学物质的作用及其在调节抗肥胖机制中的主要途径中的作用的证据。使用ScienceDirect等几个搜索引擎进行了系统的搜索,谷歌学者,和其他在线期刊,专注于实验室研究,系统评价,临床试验,和荟萃分析,集中在脂质体包裹的植物化学物质与抗肥胖特性,并遵循本系统审查的首选报告术语。最初的搜索提供了1810篇文章的结果,在纳入和排除标准之后选择93篇论文.关于植物化学物质的脂质体包封或其协同研究以对抗肥胖的研究很少;因此,这篇综述为未来的肥胖研究铺平了道路,主要对小儿肥胖人群有帮助。植物化学物质的脂质体包封提高了自由施用的植物化学物质的效率。靶向递送改善了药物利用并调节了抗肥胖途径。PPAR是肥胖的主要治疗靶标,因为其抑制脂肪细胞分化并维持能量稳态。
    A limited number of studies have directly examined the effects of liposomal encapsulated phytochemicals and their anti-obesity effects in adults. This study aimed to summarize the evidence on the effect of liposomal encapsulated phytochemicals and their role in regulating major pathways involved in the anti-obesity mechanism. A systematic search was performed using several search engines like Science Direct, Google Scholar, and other online journals, focusing on laboratory research, systematic reviews, clinical trials, and meta-analysis that focused on liposomal encapsulated phytochemicals with anti-obesity properties, and followed the preferred reporting terms for this systematic review. An initial search provided a result of 1810 articles, and 93 papers were selected after the inclusion and exclusion criteria. Very few studies have been conducted on the liposomal encapsulation of phytochemicals or its synergistic study to combat obesity; hence this review paves the way for future obesity research and is mainly helpful for the pediatric obesity population. Liposomal encapsulation of phytochemicals has improved the efficiency of freely administered phytochemicals. Targeted delivery improved drug utilization and regulated the anti-obesity pathways. PPARƔ is a major therapeutic target for obesity as it inhibits adipocyte differentiation and maintains energy homeostasis.

    Among various nanocarriers, liposomes, and micelles are relatively mature drug delivery systems with the advantages of prolonging drug half-life, reducing toxicity, and improving efficacy. However, both have problems, such as poor stability and insufficient targeting. To further exploit the excellent properties of micelles and liposomes and avoid their shortcomings, researchers have developed new drug delivery systems by combining the two and making use of their respective advantages to achieve the goals of increasing the drug loading capacity, multiple targeting, and multiple drug delivery. The results have demonstrated that this new combination approach is a very promising delivery platform. In this paper, we review the combination strategies, preparation methods, and applications of micelles and liposomes to introduce the research progress, advantages, and challenges of composite carriers.

    在过去的十年中,乳腺癌的发病率和死亡率呈指数增长,尤其是女性患者。目前的疗法,包括手术和化疗,对患者的身体和精神有显著的负面影响。作为一种更安全的选择,正在考虑利用具有治疗各种疾病潜力的治疗基因进行基因治疗。基因的递送通常利用病毒载体。然而,免疫反应甚至死亡率已被记录为副作用。因此,非病毒载体,如脂质体,由形成纳米颗粒的脂质双层组成的系统,正在研究。脂质体由于其将许多功能结合到具有所需特性和功能的系统中的无限能力而显示出巨大的潜力。本文讨论了阳离子,阴离子,和具有稳定性的中性脂质体,细胞毒性,转染能力,细胞摄取,和限制作为基因载体适用于基因疗法特别是癌症。由于采用与带负电荷的核酸和细胞膜的静电接触用于吸收目的的更实际的方法,阳离子脂质体似乎更适合用于基因递送和乳腺癌治疗的治疗。由于其他替代方案有许多复杂的额外修改,为了实现乳腺癌治疗的功能性基因治疗系统,这也在这篇综述中进行了讨论。本文旨在提高对乳腺癌基因治疗的认识,建立可行的乳腺癌基因治疗治疗策略。
    Breast cancer incidence and mortality rates have increased exponentially during the last decade, particularly among female patients. Current therapies, including surgery and chemotherapy, have significant negative physical and mental impacts on patients. As a safer alternative, gene therapy utilising a therapeutic gene with the potential to treat various ailments is being considered. Delivery of the gene generally utilises viral vectors. However, immunological reactions and even mortality have been recorded as side effects. As a result, non-viral vectors, such as liposomes, a system composed of lipid bilayers formed into nanoparticles, are being studied. Liposomes have demonstrated tremendous potential due to their limitless ability to combine many functions into a system with desirable characteristics and functionality. This article discusses cationic, anionic, and neutral liposomes with their stability, cytotoxicity, transfection ability, cellular uptake, and limitation as a gene carrier suitable for gene therapy specifically for cancer. Due to the more practical approach of employing electrostatic contact with the negatively charged nucleic acid and the cell membrane for absorption purposes, cationic liposomes appear to be more suited for formulation for gene delivery and therapy for breast cancer treatment. As the other alternatives have numerous complicated additional modifications, attachments need to be made to achieve a functional gene therapy system for breast cancer treatment, which were also discussed in this review. This review aimed to increase understanding and build a viable breast cancer gene therapy treatment strategy.
