文题释义:
富血小板纤维蛋白:2001年由Choukroun等学者提出的第2代富血小板浓缩物,为一种富含大量生长因子、血小板、白细胞的血液制品,可压制成膜状、块状或剪成碎片,在组织再生中能够为细胞生长、迁徙提供支架和空间,降低局部炎症反应,促进软硬组织的再生修复。
改良型富血小板纤维蛋白:2014年由Ghanaati等学者提出经过改良和调整的富血小板浓缩物制品,这是一种细胞分布、生长因子含量、纤维蛋白微观结构及机械性能等均与富血小板纤维蛋白有所不同的新型富血小板纤维蛋白。
摘要
背景
:自体血液制成的富血小板纤维蛋白在促进软组织再生修复方面成为研究热点。
目的:对比2种富血小板纤维蛋白对人牙龈成纤维细胞生长速度的影响,为临床中选择口腔软组织再生修复材料提供参考。
方法:阻生牙拔除同期取患牙周围健康龈瓣(8例),组织块培养法获取人牙龈成纤维细胞并进行鉴定。抽取对应患者静脉血分别制成改良型富血小板纤维蛋白、富血小板纤维蛋白,8例样本均取第5代细胞分改良型富血小板纤维蛋白、富血小板纤维蛋白、空白组3组进行培养,于第1,3,5及7天,CCK-8法检测细胞增殖活性。
结果与结论:①培养的人牙龈成纤维细胞Vimentin染色阳性,Cytokeratin染色阴性;②成功获得2种富血小板纤维蛋白凝胶;与富血小板纤维蛋白相比,改良型富血小板纤维蛋白颜色较深,膜更厚,韧性更好;③CCK-8结果显示,第1天,3组细胞增殖活性无显著差异(P > 0.05);第3天,改良型富血小板纤维蛋白和富血小板纤维蛋白组的细胞增殖活性显著高于空白组(P < 0.05);第5和7天,细胞增殖活性表现为改良型富血小板纤维蛋白组>富血小板纤维蛋白组>空白组(P < 0.01,P < 0.05);④结果提示,改良型富血小板纤维蛋白、富血小板纤维蛋白均能提高成纤维细胞增殖活性,且改良型富血小板纤维蛋白促细胞增殖效果明显优于富血小板纤维蛋白。

Abstract:

BACKGROUND: Platelet-rich fibrin (PRF) prepared by autologous blood has become the hotspot in regeneration and repair of soft tissues.
OBJECTIVE: To compare the effect of two kinds of PRFs on the proliferation activity of human gingival fibroblasts (HGFs), so as to provide reference for the selection of oral soft tissue regeneration and repair materials in the clinic.
METHODS: Healthy gingival flaps from eight patients were collected when mandibular impacted teeth were removed. HGFs were obtained using tissue explant method, and then identified. The venous blood of the corresponding patients was drawn and made into advanced PRF and PRF, respectively, and passage 5 HGFs were divided into advanced PRF, PRF and blank groups for culture. The cell proliferation activity was detected by cell counting-kit 8 assay at 1, 3, 5, and 7 days.
RESULTS AND CONCLUSION: The HGFs were positive for Vimentin staining and negative for Cytokeratin staining. Two kinds of PRFs were prepared successfully. The advanced PRF exhibited the deeper color, more thick membrane and better flexibility compared with the general PRF. Cell counting-kit 8 assay results revealed that at 1 day after culture, there was no significant difference in the proliferation activity among groups (P > 0.05). At 3 days, the cell proliferation activity in the advanced PRF and PRF groups was significantly higher than that in the blank group (P < 0.05). At 5 and 7 days, the order of cell proliferation activity was as follows: advanced PRF group > PRF group > blank group (P < 0.01, P < 0.05). To conclude, both advanced PRF and PRF can increase the proliferation activity of HGFs, especially the former.
