航海条件下血液不同保存方法对红细胞表达黏附分子的影响

目的：探讨航海过程中血袋摆放方式对红细胞表达黏附分子的影响。方法于出航训练当日，采集4位健康志愿者全血，按常规方式制备红细胞悬液，每份均分成4份，1份作为对照组保存在医院输血科冰箱，采用直立贴放方式，另3份作为实验组分别采用平铺码放、直立贴放、垂挂固定3种方式同置于舰载储血冰箱。训练结束后，立即检测送至实验室检测红细胞黏附分子CD58， CD44， CD47的表达。结果与陆地保存红细胞比较，航海条件下舰载冰箱直立贴放保存的全血中红细胞表达CD44和CD47的水平显著升高，平铺码放保存的红细胞表达CD58的水平显著降低。结论从表达黏附分子角度，航海条件下，红细胞适宜采用直立贴放方式保存于冰箱中。

The expression of adherent molecules in the preservation of human red blood cells during deployment at sea

Objective To investigate the effect of blood-bag placement mode in the refrigerator on the expression of adherent molecules in the preservation of human erythrocytes onboard the ship.Methods On the first day of deployment to sea, 4 blood samples were collected from 4 healthy volunteers.Erythrocyte suspension was equally aliquoted into four portions, one as the control group was placed vertically in the refrigerator of the hospital and the other three as the experiment group were preserved in the same refrigerator on-board the ship in 3 different placement modes ( the layer-upon-layer mode, the upright mode and the vertical suspension mode) .After completion of the training, the preserved samples were immediately sent to the laboratory for the detection of the expressions of CD47, CD58, and CD44.Results The expression levels of CD44 and CD47 in the erythrocytes of whole blood placed on the shipboard refrig-erator were significantly higher, as compared with those of the control group in the hospital.The expression levels of CD58 in the eryth-rocytes placed in the layer-upon-layer mode decreased significantly.Conclusion From the aspect of the expression of erythrocyte, the upright placement mode was most suitable for the preservation of blood in the shipboard refrigerator.
