摘要:

文题释义:

血红蛋白氧载体:以血红蛋白为原料,通过交联、聚合、偶联等化学修饰或者将其封装在人工合成的膜中,得到一种具有运载氧气能力的红细胞替代物。

红细胞替代物:通过模拟天然红细胞生物学功能的氧载体,主要包括基于全氟碳的乳剂、含铁(Fe2+)卟啉和基于血红蛋白的氧载体。与红细胞相比,红细胞替代物具有降低感染风险、延长储存时间、在使用时无需配型等优点。

背景:血红蛋白氧载体作为红细胞替代物之一,已研究40余年,至今共有3代不同的血红蛋白氧载体。第1代和第2代主要是对血红蛋白进行化学修饰,而第3代主要是将血红蛋白封装在合成膜中。

目的:综述国内外血红蛋白氧载体研究的新进展。

方法:以“hemoglobin-based oxygen carriers,red blood cell substitutes,artificial oxygen carriers ,artificial blood”“血红蛋白氧载体,红细胞替代物,人工氧载体,人工血液”为检索词,检索2000至2019年PubMed、CNKI中国期刊全文数据库、万方数据库中收录的血红蛋白氧载体制备方法的相关文献,进行总结分析。

结果与结论:①胎儿、无脊椎动物、爬行动物的血红蛋白以及β-亚基突变的血红蛋白在制备血红蛋白氧载体上有一定优点;②关于血红蛋白的修饰和封装策略有了新的进展;③联合使用其他药物能够降低血红蛋白氧载体的血管毒性;④血红蛋白氧载体在应用上有了新方向,但是新型血红蛋白氧载体作为红细胞替代物领域的研究,在未来还需要更多的动物实验和临床试验。

Abstract:

BACKGROUND: As a kind of blood substitutes, hemoglobin-based oxygen carriers have been studied for more than 40 years. The research efforts to achieve this goal have so far gone through three different generations of hemoglobin-based oxygen carriers. While the first and second generations entail the hemoglobin’s chemical modification, the third generation of hemoglobin-based oxygen carriers involves the encapsulation of hemoglobin within a synthetic membrane.

OBJECTIVE: To summarize the latest progress in hemoglobin-based oxygen carriers.

METHODS: Using “hemoglobin-based oxygen carriers, red blood cell substitutes, artificial oxygen carriers, artificial blood” as the key words in Chinese and English, respectively, we retrieved the related literatures on the preparation of hemoglobin-based oxygen carriers published from 2000 to 2019 in PubMed, CNKI, and WanFang databases.

RESULTS AND CONCLUSION: Hemoglobin from fetus, invertebrate, and reptilian and β-subunit mutant hemoglobin have certain advantages in the preparation of hemoglobin-based oxygen carriers. Latest progress has been made mainly in the modification and encapsulation of hemoglobin. And combined use of other drugs can reduce the vascular toxicity of hemoglobin-based oxygen carriers. Some new possibilities in the application of hemoglobin oxygen carriers have been found, but the application of new hemoglobin-based oxygen carriers as red blood cell substitutes needs more animal experiments and clinical trials in the future.

Key words: hemoglobin, oxygen carrier, red blood cell substitutes, artificial oxygen carrier, modification, encapsulation
