文题释义:

纳米脂肪:其颗粒大小远小于普通的颗粒脂肪,但其直径并非真正意义上的纳米级别,它的制取多是用带锐利侧孔多端口的套管,采用标准抽脂装置从患者腹部或者大腿进行负压抽脂,将所抽的脂肪用生理盐水冲洗过滤,再将过滤后的脂肪机械乳糜化,可见颗粒脂肪变成了乳糜状。
脂肪干细胞辅助脂肪移植技术:其做法是将从患者大腿或者腹部抽取的颗粒脂肪分为2部分,一部分与传统颗粒脂肪处理过程一样,而另一部分需要经过清洗、酶消化、离心等处理获取富含脂肪干细胞的血管基质成分胶,将其共同注射到移植处。
 
 
背景:近年来人们对纳米脂肪的研究也逐渐拓宽及拓深,其应用也越来越广。
目的:综述近年来纳米脂肪的研究及应用。
方法:以“Nanofat、Adipose-Derived Stem Cells、fat grafting”为英文检索词,以“纳米脂肪、脂肪干细胞、脂肪移植”为中文检索词,检索中国知网全文数据库、万方全文数据库、维普期刊全文数据库、PubMed 数据库有关纳米脂肪及脂肪干细胞的文献,保留52篇文献进一步总结分析。
结果与结论:综合目前对纳米脂肪的研究,证实纳米脂肪在抗衰老、瘢痕、创面修复、填充等效果明显,但样本数据不大,需要更大、更多的样本及数据支撑。目前制备方法得到的纳米脂肪包括多种成分,具体作用机制还需更深层次的研究,且目前制备方法尚无统一标准,诸多环节如:选取脂肪来源、抽吸脂肪方法、机械乳化过滤脂肪程序及纳米脂肪移植注射后的护理等均有待进一步完善。

Abstract:

BACKGROUND: In recent years, there is an increasing area of nano-fat and its clinical application.
OBJECTIVE: To summarize the research progress and clinical application of nano-fat.
METHODS: A computer-based online search of China Academic Journals Full-text Database, Wanfang database, VIP Chinese Technology Periodical Database, Pubmed database was performed to retrieve documents regarding nano-fat and adipose-derived stem cells with the search terms “nanofat, adipose-derived stem cells, fat grafting” in Chinese and English. Fifty-two publications were included in the final analysis.
RESULTS AND CONCLUSION: The retrieved documents have demonstrated that nano-fat exhibits obvious effects in preventing against age and scar and on would repair and filling. However, sample size is small. A larger number of studies are required to support this conclusion. The currently prepared nano-fat contains multiple components. In-depth studies are required to investigate the precise mechanisms of action. There are no unified criteria to prepare nano-fat. Many links such as selection of fat source, method of sucking fat, mechanical emulsification and filtration of fat, and nursing after nano-fat transplantation should be further improved.

Key words: nano-fat, adipose-derived stem cells, fat transplantation, anti-aging, review, fat, filling, transplantation
