摘要
癌症是目前人类所面对的共同难题,降低癌症死亡率的关键是实现早期诊断。荧光寿命因对微环境的敏感性,不仅可以实现对早期癌症组织与正常组织的区分,还可以对药物治疗癌症进行监测,因此荧光寿命成像显微技术在癌症诊断方面具有巨大的应用潜力。本文介绍了荧光寿命成像显微技术的基本原理及检测方法,总结了内源性和外源性荧光团的特征及其与癌症诊断的关系,综述了近年来荧光寿命成像显微技术在神经系统、呼吸系统、消化系统、生殖系统、泌尿系统、内分泌系统以及皮肤系统等癌症诊断中的应用,讨论了荧光寿命成像显微技术在癌症诊断中的应用优势、局限性以及未来发展趋势。
Cancer is currently a common problem facing human beings.Early diagnosis is a key factor in reducing cancer mortality.Due to its sensitivity to the microenvironment,fluorescence lifetime imaging microscopy(FLIM)can not only distinguish early cancer tissues from normal tissues,but also monitor the drug treatment of cancer.Therefore,FLIM has great application potential in cancer diagnosis.This article introduces the basic principles and detection methods of FLIM,summarizes the endogenous and exogenous fluorescence characteristics and their relationship with cancer.In addition,this article mainly reviews the recent applications of FLIM in the diagnosis of cancers in the nervous system,respiratory system,digestive system,reproductive system,urinary system,endocrine system and skin system,and discusses the application advantages,limitations and future development trends of FLIM in cancer diagnosis.
