摘要:

文题释义:
激活剂:富血小板血浆中加入激活剂能刺激富血小板血浆中的血小板迅速活化,释放高浓度生长因子,加速组织愈合。临床常用的激活剂有葡萄糖酸钙、凝血酶、葡萄糖酸钙+凝血酶混合剂。 
生长因子:是富血小板血浆中临床治疗的关键效应分子,参与组织生理病理过程的修复,主要有血小板衍生生长因子BB、血小板衍生生长因子AB、血管内皮生长因子、表皮生长因子、胰岛素样生长因子1、转化生长因子β等。不同的生长因子通过与特异的、高亲和的细胞膜受体结合,调控机体细胞增殖、迁移,促进组织修复。

背景:生长因子是富血小板血浆在临床治疗中发挥作用的关键效应分子,不同激活剂激活富血小板血浆后生长因子浓度存在差异,是影响临床疗效的重要因素。
目的:分析不同激活剂对富血小板血浆中生长因子质量浓度的影响。
方法:招募12名健康志愿者,采集EDTA-K2抗凝静脉血,应用二次离心法制备富血小板血浆。比较静脉血与富血小板血浆中生长因子的质量浓度差异。将富血小板血浆分别与4种激活剂(生理盐水、凝血酶、葡萄糖酸钙、葡萄糖酸钙+凝血酶)按照体积比10∶1混匀,置于37 ℃恒温水浴箱孵育30 min,离心后提取上清液,检测生长因子质量浓度;利用血琼脂平板检测上清液中的细菌生长情况;采用Pearson相关分析不同激活剂与富血小板血浆中生长因子质量浓度的相关性,血小板计数值与富血小板血浆中生长因子质量浓度的相关性。
结果与结论:①富血小板血浆中血小板衍生生长因子BB、血小板衍生生长因子AB、血管内皮生长因子、表皮生长因子的质量浓度分别是静脉血中对应生长因子质量浓度的8.7,22.2,2.3,2.8倍(P < 0. 05);②与生理盐水组比较,凝血酶组、葡萄糖酸钙组、葡萄糖酸钙+凝血酶组中血小板衍生生长因子BB、血小板衍生生长因子AB、血管内皮生长因子、表皮生长因子质量浓度升高(P < 0. 05);凝血酶组、葡萄糖酸钙组血小板衍生生长因子BB质量浓度高于葡萄糖酸钙+凝血酶组(P < 0. 05),凝血酶组血小板衍生生长因子AB质量浓度高于葡萄糖酸钙组、葡萄糖酸钙+凝血酶组(P < 0. 05),凝血酶组表皮生长因子质量浓度低于葡萄糖酸钙组、葡萄糖酸钙+凝血酶组(P < 0. 05);③血琼脂平板实验结果显示4组上清液中均无细菌生长;④Pearson相关分析显示,富血小板血浆中血小板衍生生长因子BB质量浓度与凝血酶存在正向强相关性(r=0.683,P < 0. 05),血管内皮生长因子质量浓度与凝血酶、葡萄糖酸钙、葡萄糖酸钙+凝血酶激混合剂存在正向强相关性(r=0.730,0.789,0.686,P < 0. 05);富血小板中血小板计数值与4种生长因子质量浓度均无相关性(P > 0. 05);⑤结果提示,不同激活剂对富血小板血浆中生长因子浓度产生不同影响,建议临床根据不同生长因子质量浓度和治疗需求选择不同激活剂,以提高临床疗效。

Abstract: BACKGROUND: Growth factor is the key effect molecule that plays a role in platelet-rich plasma in clinical treatment. There are differences in the concentration of growth factor after different activators activate platelet-rich plasma, which is an important factor affecting clinical efficacy.
OBJECTIVE: To analyze the influence of different activators on the mass concentration of growth factors in platelet-rich plasma.
METHODS: Totally 12 healthy volunteers were recruited to collect EDTA-K2 anticoagulant venous blood. Secondary centrifugation was used to prepare platelet-rich plasma. The difference in mass concentrations of growth factors was compared between venous blood and platelet-rich plasma. The platelet-rich plasma was mixed with four activators (normal saline, thrombin, calcium gluconate, calcium gluconate + thrombin) according to the volume ratio of 10:1, and incubated in a constant temperature water bath at 37 °C for 30 minutes. After centrifugation, the supernatant was extracted and the mass concentration of growth factor was detected. The bacterial growth in supernatant was measured by blood agar plate. Pearson correlation was used to analyze the correlation between different activators and the mass concentration of growth factor in platelet-rich plasma, and the correlation between the value of thrombocytometer and the mass concentration of growth factors in platelet-rich plasma.
RESULTS AND CONCLUSION: (1) The mass concentrations of platelet-derived growth factor-BB, platelet-derived growth factor-AB, vascular endothelial growth factor, and epidermal growth factor in platelet-rich plasma were 8.7, 22.2, 2.3, and 2.8 times of those in venous blood, respectively (P < 0.05). (2) Compared with normal saline group, the mass concentrations of platelet-derived growth factor BB, platelet-derived growth factor AB, vascular endothelial growth factor, and epidermal growth factor were increased in the thrombin group, calcium gluconate group, and calcium gluconate + thrombin group (P < 0.05). The mass concentration of platelet-derived growth factor BB in the thrombin group and calcium gluconate group was higher than that in the calcium gluconate + thrombin group (P < 0.05), and the mass concentration of platelet-derived growth factor AB in the thrombin group was higher than that in the calcium gluconate group and calcium gluconate + thrombin group (P < 0.05). Epidermal growth factor mass concentration in the thrombin group was lower than that in the calcium gluconate group and calcium gluconate + thrombin group (P < 0.05). (3) The results of blood agar plate test showed no bacterial growth in the supernatant of the four groups. (4) Pearson correlation analysis showed that the mass concentration of platelet-derived growth factor BB in platelet-rich plasma was strongly positively correlated with thrombin (r=0.683, P < 0.05), and the mass concentration of vascular endothelial growth factor was strongly positively correlated with thrombin, calcium gluconate, calcium gluconate + thrombin stimulant (r=0.730, 0.789, 0.686, P < 0.05). There was no correlation between the value of thrombocytometer and the mass concentration of four kinds of growth factors (P > 0.05). (5) The results suggest that different activators have an impact on the concentration of growth factors in platelet-rich plasma. It is suggested to choose different activators to improve clinical efficacy according to different growth factor mass concentrations and treatment needs.
