摘要:

文题释义:
富血小板血浆:是一种通过离心全血所获得的血小板浓缩物,含有多种生长因子,具有加速组织再生与修复的作用。
骨缺损:指部分骨骼的缺失,小部分骨缺损机体可以自我修复,但当骨缺损长度超过缺损骨横径的1.5倍时,会出现不愈合的情况,处理起来十分棘手。治疗大段骨缺损存在着周期长、成本高、疗效不可控、感染、骨不连等并发症众多的问题。

背景:研究发现,三七总皂苷联合富血小板血浆对成骨和血管化的相关因子表达具有上调作用,可促进骨不连愈合。
目的:观察富血小板血浆经三七总皂苷干预后的生长因子释放情况,以及对兔骨缺损愈合的影响。
方法:18只新西兰大白兔随机分为三七总皂苷组、对照组、空白组3组。三七总皂苷组用三七总皂苷灌胃2周;对照组予10 mL生理盐水灌胃处理2周;空白组正常饲养。三七总皂苷组与对照组一起采血离心获得富血小板血浆,激活后用ELISA法检测不同时间节点(激活后0,2 h及1,3,5,7 d)生长因子释放浓度。1周后所有动物行桡骨骨缺损造模,三七总皂苷组与对照组植入自体富血小板血浆,通过观察术后X射线片及大体组织苏木精-伊红染色结果,比较骨缺损愈合情况。实验方案已经通过广州中医药大学第一附属医院动物实验伦理委员会批准(批准号:TCMF1-2019062)。
结果与结论:①生长因子释放情况:三七总皂苷组的血管内皮生长因子A在激活后第7天、转化生长因子β在激活后第1天、碱性成纤维细胞生长因子在激活后第3,5天释放浓度高于对照组(P < 0.01);②X射线片检查骨缺损愈合情况:术后2个月三七总皂苷组的骨缺损愈合情况优于对照组;三七总皂苷组与对照组都明显优于空白组;术后3个月3组骨缺损均已愈合;③苏木精-伊红染色显示:三七总皂苷组骨小梁密度大于对照组;空白组劣于其余2组;④实验结果表明:三七总皂苷可以上调富血小板血浆释放生长因子的浓度;三七总皂苷干预后的富血小板血浆对促进兔骨缺损愈合更有优势。

Abstract: BACKGROUND: Panax notoginseng saponins combined with platelet-rich plasma can up-regulate the expression of factors related to osteogenesis and vascularization, and promote bone healing. 
OBJECTIVE: To observe the release of growth factors from platelet-rich plasma after intragastric administration of panax notoginseng saponin and its effects on bone defect healing in rabbits.
METHODS: Eighteen New Zealand white rabbits were randomly divided into three groups: PNS group, control group and blank group. PNS group was treated with panax notoginseng saponins by gavage for 2 weeks. Control group was given 10 mL of normal saline by gavage for 2 weeks. Blank group were fed normally. Platelet-rich plasma was obtained by centrifugation in the PNS group together with the control group. After activation, growth factor release was detected by ELISA at different time points (0, 2 hours, 1, 3, 5, and 7 days after activation). One week later, the model of radial bone defect was established in each rabbit. PNS and control groups were implanted with autologous platelet-rich plasma. The bone defect healing of the three groups was compared based on the results from X-ray examination, gross observation, and hematoxylin-eosin staining. The study protocol was approved by the Experimental Animal Ethics Committee of the First Affiliated Hospital of Guangzhou University of Chinese Medicine (approval No. TCMF1-2019062).
RESULTS AND CONCLUSION: The release of growth factors: In the PNS group, the release concentrations of vascular endothelial growth factor A on the 7th day, transforming growth factor-β on the 1st day, basic fibroblast growth factor on the 3rd and 5th days after activation were higher than those of the control group (P < 0.01). Bone defect healing: Two months after operation, X-ray examination results showed that better bone healing was observed in the PNS group than the control group, and bone healing in these two groups was significantly better than that in the blank group. Three months after operation, bone defects were healed in all the three groups. Hematoxylin-eosin staining results showed that the trabecular density was higher in the PNS group than the control group, and was worst in the blank group. All these findings indicate that the intervention of Panax notoginseng saponins can up-regulate the concentration of growth factors released from platelet-rich plasma, which has more advantages in promoting the healing of rabbit bone defects than the use of platelet-rich plasma alone.
