摘要
红细胞输注已广泛应用于创伤救治、外科手术、输血治疗以及战伤急救等多个方面,但依然存在血液资源紧缺、储存期短、输前需交叉配型、可能经血传播病原体等问题.血红蛋白氧载体(hemoglobin-based oxygen carriers,HBOCs)是一类由无基质血红蛋白通过化学修饰等方法制备的可溶性纳米级具有携释氧功能的氧载体,能代替红细胞为体内各器官、组织输送氧气,且具有无血型和病毒传播风险、储存长,即时可用的特点,也称为红细胞代用品.本文旨在综述HBOCs研究的进展,同时探讨其在除替代红细胞输血治疗以外,针对其他如器官保存、脑缺血、肿瘤等治疗中的应用前景.
Abstract
Red blood cell transfusion has been widely used in trauma treatment,surgery,anemia treatment,war wound emergency treatment and other aspects,but there are still problems such as shortage of blood resources,short storage period,cross-matching before transfusion,and possible transmission of pathogens through blood.Hemoglobin-based oxygen carriers(HBOCs)are a class of soluble nano-oxygen carriers prepared by chemical modification of matrix-free hemoglobin,which can replace red blood cells to transport oxygen to organs and tissues in the body.HBOCs have the characteristics of no blood group and virus transmission risk,long storage,and instant use,so they are also known as red blood cell substitutes.This paper aims to review the research progress of HBOCs,and explore their application prospects in organ preservation,cerebral ischemia,tumor treatment and other treatments in addition to the replacement of red blood cell transfusion.
