文题释义:
红车轴草:
红车轴草为豆科三叶草草本植物,主要含有黄酮类、多糖和蛋白质等化学成分。黄酮类中异黄酮为主要成分,现代研究发现红车轴草异黄酮具有抗癌、植物雌激素样作用、降血脂和抗炎等作用;民间采用红车轴草花序煎剂祛痰、治感冒和肺结核、利尿和消炎,外敷治脓肿、烧伤和眼疾等,并有应用花、种子、植株及根部制膏、浸膏、糊剂、煎剂和泡茶饮用,对于骨质疏松有一定的防治作用。
破骨细胞:破骨细胞来源于骨髓单核髓系造血干细胞,是唯一的骨吸收细胞,在骨代谢过程中起着至关重要的作用,骨代谢中骨吸收受到细胞因子、转录因子和淋巴细胞对破骨细胞的直接调节,也可以通过成骨细胞间接调节破骨细胞分化;在临床中破骨细胞与骨质疏松、类风湿性关节炎等许多疾病发生有关,阐明破骨细胞的分化及功能机制,可以为相关临床疾病的治疗提供新的靶点和思路。

 

摘要
背景:
最近研究发现红车轴草异黄酮能够通过提高雌激素作用,有效抑制骨吸收,降低骨转化率,增强成骨细胞活性及骨密度,对骨质疏松具有一定的防治作用。
目的:观察红车轴草提取物对破骨细胞骨吸收及分化的作用影响。
方法:提取大鼠骨髓腔细胞,用淋巴细胞分离液分离细胞,培养5 h后,取未贴壁细胞加入30 μg/L巨噬细胞集落刺激因子和75 μg/L核因子κB受体活化因子配体诱导细胞(对照组),将不同质量浓度(0.3,0.6和1.2 g/L)的红车轴草提取物加入诱导的破骨细胞中,观察不同质量浓度的红车轴草提取物对破骨细胞分化与骨吸收作用;采用Western bloting法测定破骨细胞分化相关蛋白c-fos和NFATcl的含量。
结果与结论:①与对照组比较,不同质量浓度的红车轴草提取物能够不同程度的抑制破骨细胞分化和骨吸收;②抗酒石酸酸性磷酸酶染色发现红车轴草提取物能够明显降低破骨细胞数目;③Western blotting 结果表明红车轴草提取物能够抑制破骨细胞分化相关蛋白c-fos和NFATC1表达;④结果提示,红车轴草提取物能够抑制破骨细胞分化及骨吸收。

Abstract:

BACKGROUND: Isoflavone isolated from Trifolium pratense L. has been found to be able to effectively inhibit bone resorption, reduce bone turnover rate, improve osteocyte activity and bone mineral density by enhancing the effect of estrogen, which is helpful for the prevention and treatment of osteoporosis.
OBJECTIVE: To investigate the effect of Trifolium pratense L. extracts on the bone resorption and differentiation of osteoclasts.
METHODS: Rat bone marrow cells were extracted, isolated by lymphocyte separation and cultured for 5 hours; then, the non-adherent cells were selected followed by induced by 30 μg/L macrophage colony stimulating factor and 75 μg/L RANKL (control groups), or different concentrations of Trifolium pratense L. extracts (0.3, 0.6 and 1.2 g/L) to observe their effect on the osteoclast differentiation and bone resorption. The levels of osteoclast differentiation-associated proteins c-fos and NFATcl were determined by western blot assay.
RESULTS AND CONCLUSION: Compared with the control group, different concentrations of Trifolium pratense L. extracts could suppress osteoclast differentiation and bone resorption to different degrees. Tartrate-resistant acid phosphatase staining showed that Trifolium pratense L. extracts could significantly reduce the number of osteoclasts. Western blot assay results suggest that Trifolium pratense L. extracts significantly inhibited the expression levels of c-fos and NFATcl. These results reveal that Trifolium pratense L. extracts can inhibit osteoclast differentiation and bone resorption.
