摘要:

文题释义:
纳米水凝胶:作为一种联合纳米颗粒和水凝胶优势的纳米材料,其尺寸保持在纳米级别(通常直径< 200 nm),与微米水凝胶(直径0.5-1.0 µm)及大尺寸水凝胶相比具有更为实用的应用潜力。
影像诊疗一体化:即将医学影像与临床诊疗过程紧密结合,并由此形成的连续、高效、精准的医疗服务体系。随着医疗技术的快速发展,医学影像在疾病诊断中发挥着越来越重要的作用,而影像诊疗一体化的提出正是为了充分融合医学影像与临床诊疗的优势,旨在提高疾病的诊断准确性和治疗效率。

背景:纳米水凝胶可联合纳米颗粒和水凝胶特性,具备多重优势,在临床转化中发挥了巨大作用。
目的:归纳总结纳米水凝胶的自身及交联特性,结合纳米水凝胶的功能可视化应用特点,总结它在可视化影像诊疗的多重应用策略。
方法:检索 PubMed、Web of Science、中国知网和万方数据库中收录的相关文献,以“纳米水凝胶,成像,磁共振成像,荧光成像,超声成像,光声成像,多模态成像,治疗”为中文检索词,以“nanogel,nanohydrogel,imaging, magnetic resonance imaging,fluorescence imaging,ultrasound imaging,photoacoustic imaging,multimodal imaging,therapy,treatment”为英文检索词,根据入选标准最终选定78篇文献进行综述。
结果及结论:纳米水凝胶的制备过程受其多重特性及交联机制的显著影响,优化这些特性与机制有助于提升纳米水凝胶的结构性能,进而加速其临床应用的转化。随着诊疗一体化趋势的不断发展,功能可视化纳米水凝胶能够借助磁共振成像、荧光成像、超声成像、光声成像以及多模态成像等多种技术手段,实现肿瘤的有效显影,并在多种疾病的治疗策略中展现出关键价值,这些研究成果不仅为纳米水凝胶的后续制备过程的优化开辟了新途径,也为其临床转化进程的加速奠定了坚实基础。

Abstract: BACKGROUND: Nanogels can combine the properties of nanoparticles and hydrogels, which have multiple advantages and can play a great role in clinical translation.  
OJECTIVE: To summarize the self- and cross-linking properties of nanogels, the diagnostic and therapeutic integration strategies they played in a variety of imaging processes, in conjunction with their functional visualization and application properties.
METHODS: By searching PubMed, Web of Science, CNKI, and Wanfang databases, English and Chinese search terms were “nanogel, nanohydrogel, imaging, magnetic resonance imaging, fluorescence imaging, ultrasound imaging, photoacoustic imaging, multimodal imaging, therapy, treatment.” According to the inclusion criteria, 78 articles were finally selected for review. 
RESULTS AND CONCLUSION: The preparation process of nanogels is significantly affected by their multiple properties and cross-linking mechanisms. Optimization of these properties and mechanisms can help to improve their structural performance and accelerate the translation of their clinical applications. With the trend of integrated diagnosis and treatment, functional visualization of nanogels can effectively image tumors with the help of magnetic resonance imaging, fluorescence imaging, ultrasonography, photoacoustic imaging, and multimodal imaging, which can be of key value in the treatment strategies of various diseases. These findings not only pave the way for improving the preparation methods of nanogels, but also create a robust groundwork for hastening their clinical translation.


Key words: nanogel, visualization, imaging, integrated diagnosis and treatment, therapy, engineered material
