摘要: 目的 比较MAP重悬洗涤红细胞与悬浮红细胞在储存过程中的细胞膜蛋白及pH的动态变化,确定MAP重悬洗涤红细胞的最适合保存期。方法 将同一来源压积红细胞均分为两组,分别制备成悬浮红细胞和MAP重悬洗涤红细胞;在储存第2、7、14、21、28和35天,检测两组红细胞膜表面蛋白(CD47、CD55、CD59、CD147、PS外翻率)及pH值。结果 MAP重悬洗涤红细胞各检测时间点pH值显著低于悬浮红细胞(P<0.05)。储存至35天,与悬浮红细胞相比,MAP组CD47,CD55和CD59表达量明显降低(P<0.01),PS外翻率明显升高(P<0.01),CD147表达量下降但无统计学意义。红细胞膜蛋白变化与pH值存在显著相关性(P<0.01)。结论 MAP重悬洗涤红细胞在短期(≤21 d)储存中质量不低于悬浮红细胞,建议MAP重悬洗涤红细胞的最适保存期为21 d,以确保输注安全性与有效性。

Abstract: Objective To compare membrane proteins dynamics and pH changes between MAP-suspended washed RBCs and suspended RBCs to determine the optimal storage period for MAP-suspended washed RBCs. Methods Packed RBCs were equally divided into two groups: suspended RBCs and MAP-suspended washed RBCs. Membrane protein expression (CD47, CD55, CD59, CD147) and PS externalization rate, along with pH values, were measured on storage days 2, 7, 14, 21, 28, and 35. Results The pH values of MAP-suspended washed RBCs were significantly lower than those of suspended RBCs at all timepoints (P<0.05). By day 35, MAP-suspended washed RBCs showed significantly reduced CD47, CD55, and CD59 expression (P<0.01), elevated PS externalization (P<0.01), and a non-significant decline in CD147. A significant correlation was observed between membrane protein changes and pH values (P<0.01). Conclusion The quality of MAP-suspended washed RBCs not inferior to that of suspended RBCs during short-term storage (≤21 days). It is recommended that the optimal storage period for MAP resuspended washed RBCs be 21 days to ensure the safety and efficacy of transfusion.
