Popis: Objective To investigate the quality changes of suspended red blood cells (SRBCs) prepared from the blood of Tibetan high Hb population, and explore the availability and safety of blood collected from Tibetan high Hb population. Methods The voluntary blood donors were grouped according to the Hb concentration at the initial screening: female blood donors from Tibet Autonomous Region (>3 500 m) with Hb≥190 g/L and male blood donors with Hb≥210 g/L were classified as plateau high hemoglobin group. A total of 13 male blood donors from Tibet Autonomous Region were recruited. And the female blood donors (n=13) with Hb(115~165) g/L and male blood donors (n=12) with Hb(120~185) g/L from Chengdu were classified as control group. Whole blood of 200 mL specification was centrifuged to remove the plasma, and MAP additive solution was added to prepare SRBCs, then SRBCs were divided into four aliquots (50 mL/bag and stored at 4℃. Parameters as blood routine, free Hb and hemolysis rate were measured aseptically at day 1, 14, 21, 35 of storage. And 10 mL SRBCs was used to extract membrane proteins for tyrosine phosphorylation detection of band 3 protein. Results The RBCs counts(×1012/L), hematocrit(%) and hemoglobin(g/L) of Tibetan high Hb group and control group were 6.76±0.95 vs 4.65±0.52, 63.3±6.8 vs 43.1±4.4 and 214.4±19.8 vs 143.2±16.9 (P
