冷冻保存血小板的研究进展

摘要

冷冻保护剂和添加液的正确选择是保证冷冻血小板质量的重要因素.冷冻血小板体内即刻止血功能明显优于液体保存血小板.为更好地保证冷冻血小板的质量,了解二甲亚砜(DMSO)在冷冻血小板保存过程中的作用及其作用机理、DMSO冷冻血小板止血功能增强的机理及不同因素对冷冻保存血小板的影响具有重要意义.本文就冷冻血小板的长期保存及质量标准、DMSO引起冷冻血小板分子改变及抑制激活作用的机理、不同因素对冷冻血小板保存效果的影响、保存效果的检测、冷冻血小板在灾害救援和军事行动中的应用及犬冷冻血小板的研究进行综述.%The right choice of frozen protective agents and additives is an important factor to ensure the quality of frozen platelets. The immediate hemostatic function of frozen platelet in vivo is superior to liquid-stored platelets. In order to ensure the quality of frozen platelets better, it is important to understand the role of dimethylsulfoxide (DMSO) in the preservation of frozen platelets and its mechanism, and to understand the mechanism of DMSO enhancing the hemostatic function of frozen platelets and the effects of different factors on the frozen platelets. In this review, the long-term preservation of frozen platelets and its quality standards, the mechanism of DMSO effect on the molecular changes and inhibition of frozen platelets, different factors influencing preservation freezing platelets and the test of preservation effects, the application of frozen platelets to the military openation and disaster relief, the canine frozen platelet studies and so on are summarined.
