Abstract:
Objective:To evaluate the effect of stored autologous blood transfusion on the function of bone marrow hematopoietic stem cells and the recovery of reticulocytes in peripheral blood of rabbits.Methods:Thirty healthy male New Zealand rabbits, aged 3-6 months, weighing 2.5-3.0 kg, were divided into 5 groups ( n=6 each) using a random number table method: control group (C group), operation group (O group), blood collection group (O+ B group), stored autologous whole blood group (O+ WB group) and stored autologous component blood group (O+ CB group). In O+ B group, O+ WB group and O+ CB group, blood was collected via the right femoral artery at a rate of 3-5 ml/min at 7 days before surgery, the blood volume was 10% of the total blood volume, and blood was stored at 4-6 ℃.In O+ CB group, blood was centrifuged to remove plasma and white blood cells, and red blood cell suspension was prepared and placed in a blood storage bag.In O, O+ B, O+ WB and O+ CB groups, hepatectomy was performed, and bleeding was performed through the right femoral artery at a rate of 3-5 ml/min, and the blood volume was 10% of the total blood volume.Lactated Ringer′s solution 1 ml/min was intravenously infused during surgery in O and O+ B groups, stored autologous whole blood was intravenously infused during surgery in group O+ WB, and stored autologous red blood cell suspension 1 ml/min was intravenously infused during surgery in group O+ CB.Bone marrow blood samples were collected immediately before the start of surgery (T 2) and at 6 and 24 h after surgery (T 3, 4) to determine the percentage of CD34 + cells, cell cycle and relative expression of telomere DNA.Peripheral venous blood samples were collected before storage (T 1) and at T 4 for determination of the percentage of reticulocytes. Results:Compared with group C, the percentage of CD34 + cells was significantly increased at T 3 and T 4, the percentage of CD34 + cells in G1 phase was decreased, and the expression of telomere DNA in CD34 + cells was up-regulated in group O, and the percentage of reticulocyte in peripheral blood was increased at T 4 in the remaining 4 groups ( P<0.05). Compared with group O, the percentage of CD34 + cells was significantly increased at T 2-4, the percentage of CD34 + cells in G1 phase was decreased, and the expression of telomere DNA in CD34 + cells was up-regulated in O+ B, O+ WB and O+ CB groups, and the percentage of reticulocyte in peripheral blood was increased at T 4 in O+ WB and O+ CB groups ( P<0.05). Compared with group O+ B, the percentage of CD34 + cells was significantly increased at T 3 and T 4, the percentage of CD34 + cells in G1 phase was decreased, and the expression of telomere DNA in CD34 + cells was up-regulated in O+ WB and O+ CB groups, and the percentage of reticulocyte in peripheral blood was decreased at T 4 in O+ WB and O+ CB groups ( P<0.05). Compared with O+ WB group, the percentage of CD34 + cells was significantly decreased at T 3 and T 4, the percentage of CD34 + cells in G 1 phase was increased, the expression of telomere DNA in CD34 + cells was down-regulated, and the percentage of reticulocytes in peripheral blood was increased at T 4 in group O+ CB ( P<0.05). Conclusion:Stored autologous blood transfusion can inhibit the function of bone marrow hematopoietic stem cells and is not helpful for recovery of reticulocytes in peripheral blood of rabbits; stored autologous component blood transfusion has less effect on the hematopoietic function of bone marrow than stored autologous whole blood transfusion.
