淫羊藿甙联合运动疗法是一种有效的治疗方式用于绝经后骨质疏松症

目的： 这个研究的主要目的是探究淫羊藿甙联合运动疗法对于骨质和去卵巢大鼠的影响。 方法： 去卵巢大鼠被用于绝经后骨质疏松模型，分组接受淫羊藿甙、运动疗法、激素替代疗法、以及淫羊藿甙联合运动疗法。未处理的去卵巢大鼠被用作对照组。3个月的实验间期后，大鼠的体重、卵巢的重量、骨质的物理以及生物学特性，Osx的表达量被检测。 结果：空白组去卵巢大鼠的体重增加量高于实验处理组。卵巢重量和血清雌激素的含量显著高于对照组，激素替代组。生物力学参数在单纯运动疗法组和运动合并淫羊藿甙组得到显著的提高。Osx的表达在运动联合淫羊藿甙组和淫羊藿甙组显著增加。 结论：运动联合淫羊藿甙在对去卵巢大鼠早起预防骨质疏松有显著疗效。淫羊藿甙和运动疗法在骨质疏松方面值得更进一步研究。

Icariin associated with exercise therapy is an effective treatment of postmenopausal osteoporosis

ABSTRACT PURPOSE: The purpose of this study was to investigate the effects of icariin treatment combined with exercise therapy on bone parameters and body weight of ovariectomized rats. METHODS: Ovariectomized rats were used as a model of postmenopausal osteoporosis and were exposed to either icariin treatment, exercise, hormone replacement therapy, or a combination of the above. Untreated, ovariectomized rats and sham operated rats were used as controls. After 3 months of experimental interventions the effects of the treatments on body and uterine weights, the physical and biomechanical properties of bone, and the expression of the osteoblast-specific gene Osterix (Osx), were assessed. RESULTS: The weight gain of the ovariectomized rats was greater than that of the treated experimental groups. Uterine weight and serum estradiol levels were significantly greater in sham operated and estrogen-treated ovariectomized rats than in the other groups. Biomechanical parameters were improved significantly in ovariectomized rats treated with exercise alone or treated with exercise and icariin. Osx expression was increased in ovariectomized rats treated with exercise and icariin or treated with just icariin. CONCLUSION: Exercise combined with icariin had a synergistic effect in the early prevention of osteoporosis in ovariectomized rats. The effects of icariin and exercise on osteoporosis are worth further exploration.
