Journal Title: Chinese Journal of Blood Transfusion - Year 2023, Vol 36, Issue 8
Abstract
Objective To investigate the effects of different anticoagulants on platelet-rich plasma(PRP) release content of growth factor and injection pain. Methods A total of 15 voluntary blood donors were selected, with each blood donor using four kinds of anticoagulant tubes with EDTA-K2 anticoagulation, EDTA-NA2 anticoagulation, citrate anticoagulation, ACD-A anticoagulation respectively as group A, B, C and D. PRP was isolated and prepared by the rich plasma method, and the contents of PDGF-AA, TGF-β, IGF-1, VEGF, and PF-4 were detected by enzyme-linked immunosorbent assay. Meanwhile, SD rats (20, 4 / group) were injected subcutaneously or intradermally with the supernatant of PRP and PG gel prepared in the 4 groups and normal saline in the control group. The pain status of SD rats during the injection was observed and recorded. The pain status of the 5 groups of experimental animals was evaluated according to the American Laboratory Animal Pain Guide. Results The platelet counts in PRP in group D was the highest [(1 294.53±277.37) × 109/L], which was significantly higher than that in group A [ (789.13±377.13) ×109/L] and group C [ (990.94±493.12) ×109/L] (P<0.05). The OD value of PDGF-AA in group A, B, C, and D were 1.51± 0.18, 1.69±0.21, 0.66±0.19and 1.72±0.13, respectively, with statistically significant difference between groups (P<0.05 ) and group D better than the other three groups. The OD value of PF-4 was 1.18±0.24, 1.61±0.14, 0.65±0.26 and 1.72±0.10 respectively, with statistically significant difference between groups (P<0.05) and group D better than other three groups. The OD value of IGF-1 was 1.02±0.08, 0.98±0.11, 1.06±0.11 and 1.32±0.65 respectively, with no significant difference between groups (P>0.05). The OD value of VEGF was 0.13±0.04, 0.21±0.14, 0.08±0.02 and 0.13±0.04 respectively, with statistically significant difference between group B and C (P<0.05). The OD value of TGF-β was 0.14±0.01, 0.15±0.01, 0.28±0.17 and 1.10±0.37 respectively, with statistically significant difference between groups (P<0.05) and group D better than other three groups. Comparison of injection pain: when the supernatant of PRP and PG gel was injected, there were significant differences between group A, B, C and D, and the control group (P<0.05) . The median pain scores of PRP injection of group A, B, C, and D were 6 (1.5), 5 (0.75), 4.5 (2.5), and 3(3) respectively, with group D lower than other three groups, and no statistically significant difference was noticed (P>0.05) . The median pain scores of the PG supernatant injection of group A, B, C, and D were 4 (2.25), 3 (2.75), 4 (3), 1 (1.5), and the difference was not statistically significant (P>0.05). There was no significant difference between the PRP injection group and the PG supernatant group (P> 0.05). Conclusion PRP prepared by two-step centrifugation with ACD-A anticoagulant can obtain the higher platelet counts and the maximum release of PDGF-AA, PF-4, IGF-1, and TGF-β. In terms of pain, ACD-A anticoagulant injection has the lowest pain with the animals.
