摘要:

背景:骨质疏松的发病率在逐年上升,对人类的健康危害更加明显,寻找合适有效治疗方法及治疗药物,可以减轻患者以及社会的负担。
目的:分析多种天然多糖类物质对骨质疏松的治疗作用,明确天然多糖对骨质疏松干预作用机制及作用效果。
方法:对枸杞多糖、巴戟天多糖、黄芪多糖以及黄精多糖治疗骨质疏松进行动物实验模型分析,建立去势骨质疏松模型大鼠,通过检测骨密度、骨钙含量、白细胞介素1、白细胞介素6以及一氧化氮合酶、肿瘤坏死因子等相关生化指标评价天然多糖对骨质疏松的治疗作用。
结果与结论:枸杞多糖通过调节钙的吸收与排泄、一氧化氮水平以及肿瘤坏死因子α和转化生长因子β的表达水平发挥治疗骨质疏松的作用;巴戟天多糖通过调节白细胞介素1和肿瘤坏死因子的表达水平发挥治疗骨质疏松的作用;黄芪多糖通过免疫功能及造血功能的调节发挥治疗骨质疏松的作用;黄精多糖通过调节骨钙素和抗酒石酸酸性磷酸酶的表达活性发挥治疗骨质疏松的作用。上述4种天然多糖物质在去势骨质疏松大鼠模型中均显示出较好的治疗效果。

Abstract:

BACKGROUND: The incidence of osteoporosis is increasing every year, which becomes more and more harmful to the human health. Finding a suitable and effective treatment method and drugs can reduce patients’ and social burden.
OBJECTIVE: To analyze the therapeutic effect of various kinds of nature polysaccharide on osteoporosis, and to clarify the effect and mechanism of polysaccharide intervention on osteoporosis.
METHODS: Animal experiments were performed to analyze the effect of wolfberry polysaccharide, morinda officinalis how polysaccharide, astragalus polysaccharide and polygonatum polysaccharide on the treatment of osteoporosis. A rat model of castration osteoporosis was established. The effect of nature polysaccharide on the treatment of osteoporosis was evaluated through detecting the relevant biochemical markers, such as the bone mineral density, bone calcium content, interleukin-1 level, interleukin-6 level, nitric oxide synthase level and tumor necrosis factor level.
RESULTS AND CONCLUSION: The wolfberry polysaccharide has the therapeutic effect on osteoporosis through adjusting the absorption and excretion of calcium and the expression of nitric oxide level, tumor necrosis factor-α and transforming growth factor-β. Morinda officinalis how polysaccharide plays the therapeutic effect on osteoporosis through adjusting the expression level of interleukin-1 and tumor necrosis factor. Astragalus polysaccharide can be used to treat osteoporosis by adjusting the immune function and hematopoietic function. Polygonatum polysaccharide exerts the therapeutic effect on osteoporosis through adjusting the expression osteocalcin and tartrate-resistant acid phosphatase activity. All the four kinds of nature polysaccharides have the better therapeutic effect in the rat model of castration osteoporosis.
