Abstract:
Objective:To evaluate the effect of novel erythrocyte preservation solution on the quality of erythrocytes in stored blood of type 2 diabetes mellitus (T2DM) rats.Methods:Forty SPF male Sprague-Dawley rats, aged 8 weeks, weighing 180-220 g, were used in this study. Ten rats randomly selected served as conventional erythrocyte preservation solution group (group A). T2DM model was prepared in the remaining 30 rats. Twenty T2DM rats were divided into 2 groups ( n=10 each) using a random number table method: T2DM conventional erythrocyte preservation solution control group (group C) and T2DM novel erythrocyte preservation solution observation group (group Y). Erythrocyte preservation solution was prepared to simulate the preoperative autologous blood donation process, and blood was collected from the tail vein to isolate the red blood cells, and then the corresponding preservation solution was added. Immediately after blood collection (T 0) and at 7, 14 and 21 days of preservation (T 1-3), the morphological structure of erythrocytes was observed with a light microscope, and the concentrations of 2, 3-diphosphoglycerate (2, 3-DPG) and reactive oxygen species (ROS) were also determined by enzyme-linked immunosorbent assay at T 0-T 3 and 28 days of preservation (T 4). PKH26 was used to label the erythrocytes stored in vitro for 28 days, and then the erythrocytes were transfused back into rats. The survival rate of erythrocytes was detected by flow cytometry at 1, 7, 13 and 18 h after retransfusion. Results:The erythrocyte damage was aggravated at different time points of preservation in group C when compared with group A. Compared with group C, the damage to erythrocytes was significantly alleviated at different time points of preservation in group Y. Compared with group A, the concentration of 2, 3-DPG in erythrocytes was significantly decreased at T 0 and T 2-T 4, the concentration of ROS was increased at T 0-T 4, and the survival rate of erythrocytes was decreased at 1, 7 and 18 h after retransfusion in group C ( P<0.05). Compared with group C, the concentration of 2, 3-DPG in erythrocytes was significantly increased at T 0-T 4, the content of ROS was decreased at T 1, T 3 and T 4, and the survival rate of erythrocytes was increased at 1, 7 and 18 h after retransfusion in group Y ( P<0.05). Conclusions:The novel erythrocyte preservation solution can improve the quality of stored erythrocytes and increase the survival rate of erythrocytes in vivo after retransfusion in T2DM rats.
