| 目的 利用泼尼松诱导的斑马鱼骨质疏松模型评价中药复方桃红四物汤的抗骨质疏松的作用。方法 选择发育正常的3 dpf 斑马鱼胚胎，用10 μg/mL泼尼松处理建立斑马鱼骨质疏松症模型，加入不同浓度（50、150和450 μg/mL）的中药复方桃红四物汤。同时设置正常对照组、模型对照组和阳性对照药依替膦酸二钠组。4 d后，用0.2 %钙黄绿素进行染色，在体视荧光显微镜下观察，拍照并计算斑马鱼脊椎骨的荧光强度。结果 与正常对照组相比，泼尼松处理的模型对照组的斑马鱼脊椎骨荧光强度显著减少; 与模型对照组比较，依替膦酸二钠能增加斑马鱼脊椎骨矿化量并有效防止泼尼松龙诱导斑马鱼产生的骨质疏松; 与模型对照组比较，450 μg/mL浓度的桃红四物汤能显著提高斑马鱼脊椎骨骨骼的荧光强度，而50 μg/mL和150 μg/mL浓度的桃红四物汤溶液组效果均不明显。结论 桃红四物汤对斑马鱼的最大耐药浓度MTC为450 μg/mL，并对泼尼松诱导的斑马鱼骨质疏松模型有明显的改善治疗作用。 |

| Objective To evaluate the anti-osteoporosis effect of traditional Chinese medicine Taohong Siwu Decoction by the use of prednisone-induced zebrafish osteoporosis model. Methods We selected 3 dpf normal growth zebrafish embryos, established zebrafish osteoporosis models using prednisone treatment, which were then treated with different concentrations (50, 150 and 450 μg/mL) of lyophilized powder of traditional Chinese medicine compound Taohong Siwu Decoction. At the same time, the normal control group, the model control group and the positive control group were established. After 4 days, these zebrafish were dyed for 2 h by 0.2 % calcein, and then the fluorescence intensity of vertebrae of zebrafish were observed and calculated using stereo fluorescence microscope. Results Compared with the normal control group, prednisone-treated model group had significantly lower vertebral fluorescent density; compared with the model group, Etidronate Disodium of 300 μg/mL can increase the amount of vertebrae mineralization and effectively prevent osteoporosis induced by prednisone; compared with the model group, 450 μg/mL concentration of Taohong Siwu Decoction can significantly improve the zebrafish vertebral fluorescence intensity, while the effects of the two groups of Taohong Siwu Decoction solution at 50 μg/mL and 150 μg/mL concentration were not obvious. Conclusions The Compound Chinese medicine Taohong Siwu Decoction, with a maximum concentration of drug resistance MTC of 450 μg/mL on zebrafish, had obvious therapeutic effects on zebrafish osteoporosis model induced by prednisone. |
