摘要:


文题释义:

三花接骨散:是中药制剂,20世纪90年代初期由首都医科大学等多家医疗教研单位研发而成,由三七、西红花、当归、川芎、血竭、桂枝、大黄、地龙、马钱子粉、煅自然铜、土鳖虫、续断、牛膝、烫骨碎补、木香、沉香、冰片、白芷等中药组成,具有活血化瘀、消肿止痛、接骨续筋的作用。
成骨细胞:与成纤维细胞、脂肪细胞同源,均源于间充质始祖细胞分化而来。成骨细胞是骨形成的主要功能细胞,其主要功能是介导骨基质的合成、分泌和矿化,负责新骨生成,与破骨细胞共同负责骨重建修复。其在骨形成过程中分为成骨细胞增殖、细胞外基质成熟、细胞外基质矿化和成骨细胞凋亡等4个阶段。

背景:三花接骨散为临床骨折筋伤常用药,使用效果良好,但缺少相关实验学依据,其作用机制尚不明确。
目的:观察三花接骨散对成骨细胞Wnt/β-Catenin信号通路的影响。
方法:首先预实验筛选三花接骨散干预成骨细胞的最佳浓度,之后采用CCK-8法进行成骨细胞增殖实验,碱性磷酸酶检测成骨细胞成熟度,RT-PCR检测碱性磷酸酶、Runt相关转录因子2、骨钙蛋白、骨桥蛋白、胶原酶Ⅰ、Axin2、Dkk4、Lef-1、Tcf-1 mRNA表达,Western blot法检测β-Catenin、P-β-Catenin蛋白表达。
结果与结论:①成骨细胞培养5 d后,10 mg/L质量浓度时成骨细胞数量最多;②成骨细胞培养21 d后,三花接骨散不同浓度组的细胞增殖数量均有增加,以10 mg/L组明显,但20 mg/L已有减少的趋势;③成骨细胞培养7 d后,三花接骨散低、中、高剂量组碱性磷酸酶表达均有增加,以高剂量组(20 mg/L)明显;④成骨细胞培养7 d后,三花接骨散低、中、高剂量组碱性磷酸酶、Runt相关转录因子2、骨钙蛋白,骨桥蛋白,胶原酶ⅠmRNA表达均有增加,以高剂量组(20 mg/L)明显;⑤成骨细胞培养21 d后,三花接骨散低、中、高剂量组Axin2、Dkk4 mRNA表达均有降低,Lef-1、Tcf-1 mRNA表达增加,以高剂量组(20 mg/L)明显;⑥成骨细胞培养21 d后,三花接骨散低、中、高剂量组P-β-Catenin蛋白表达均有降低,β-Catenin蛋白表达增加,均以高剂量组(20 mg/L)明显;⑦提示三花接骨散可调控成骨细胞Wnt/β-Catenin信号通路,促进碱性磷酸酶、Runt相关转录因子2、骨钙蛋白、骨桥蛋白、胶原酶Ⅰ、Lef-1、Tcf-1 mRNA以及β-Catenin蛋白表达,降低Axin2、Dkk4 mRNA以及P-β-Catenin蛋白表达,促进成骨细胞的增殖,这可能是其促进骨折愈合的作用机制。

Abstract: BACKGROUND: Sanhua Jiegu San is a common drug for clinical fracture and tendon injury, which have good effect. However, there is a lack of relevant experimental evidence, and its mechanism of action remains unclear. 
OBJECTIVE: To observe the effect of Sanhua Jiegu San on Wnt/β-catenin signaling pathway in osteoblasts. 
METHODS: Firstly, the optimal concentration of Sanhua Jiegu San for osteoblast intervention was screened by pre-experiment. Then, the proliferation of osteoblasts was tested by cell counting kit-8 method. The maturity of osteoblasts was detected by alkaline phosphatase assay. The mRNA expressions of alkaline phosphatase, Runt-related transcription factor 2, osteocalcin, osteopontin, collagenase I, Axin2, Dkk4, Lef-1, and Tcf-1 were detected by PCR. The protein expressions of β-Catenin and P-β-Catenin were detected by western blot method. 
RESULTS AND CONCLUSION: After 5 days of osteoblast culture, the number of osteoblasts reached the maximum at the concentration of 10 mg/L. After 21 days of osteoblast culture, the proliferation of cells in different concentration groups of Sanhua Jiegu San increased, which was obvious in the 10 mg/L group, but tended to decrease at 20 mg/L. After 7 days of osteoblast culture, alkaline phosphatase expression was increased in the low, medium and high concentration groups, especially in the high concentration group (20 mg/L). After 7 days of osteoblast culture, mRNA expressions of alkaline phosphatase, Runt-related transcription factor 2, osteocalcin, osteopontin, collagenase I were increased in the low, medium and high concentration groups, especially in the high concentration group (20 mg/L). After 21 days of osteoblast culture, the mRNA expressions of Axin2 and Dkk4 were decreased in the low, medium and high concentration groups, while the mRNA expressions of Lef-1 and Tcf-1 were increased, especially in the high concentration group (20 mg/L). After 21 days of osteoblast culture, the expression of P-β-Catenin protein was decreased in the low, medium and high concentration groups, while the expression of β-Catenin protein was increased, especially in the high concentration group (20 mg/L). To conclude, Sanhua Jiegu San can regulate the Wnt/β-Catenin signaling pathway in osteoblasts, promote the mRNA expression of alkaline phosphatase, Runt-related transcription factor 2, osteocalcin, osteopontin, collagenase I, Lef-1, and Tcf-1 and the protein expression of β-Catenin, and decrease the mRNA expression of Axin2 and Dkk4 and the protein expression of P-β-Catenin, thereby promoting osteoblast proliferation. This may be the mechanism by which Sanhua Jiegu San promotes fracture healing.
