摘要
Abstract Objective To explore the effect of anticoagulant on platelet recovery and enrichment coefficient of platelet-rich plasma and the optimal dose. Methods Nine New Zealand rabbits were divided into 9 groups with 1 rabbit in each group. Platelet recovery rate, enrichment coefficient, platelet-derived factor (PDGF), transforming growth factor (TGF-β1) contents were observed. Results The enrichment coefficient and platelet recovery of conventional blood + 120% sodium citrate group were the highest, the high dose blood + 120% sodium citrate group was the lowest, the conventional blood + 120% sodium citrate group was the lowest, and the low dose blood + 80% sodium citrate group was the most. Before plasma activation, the expressions of PDGF and TGF-β1 were significantly increased in the other groups compared with the control group, and were higher in the high-concentration blood group. Compared with before activation, TGF-β1 was significantly decreased in the low concentration blood group after activation; TGF-β1 was significantly decreased in the high concentration blood + 80% sodium citrate group; PDGF showed a downward trend in the high concentration blood group; the expression of PDGF was significantly decreased in each group after activation; TGF-β1 was significantly increased in the conventional blood + 120% sodium citrate group. TGF-β1 was significantly decreased in patients treated with low concentration of 80%, 100%, 120% sodium citrate and high concentration of blood + 80% sodium citrate. Conclusion Anticoagulant 120% sodium citrate in conventional blood could separate more platelets, and the enrichment coefficient and platelet recovery rate were the highest, and the biological function was good.
