目的:明确红曲对去卵巢大鼠骨质疏松模型血清ALP,TRAP及骨组织TNF-α,RANK表达的影响。方法:取12周龄Wistar雌性大鼠40只,随机分为结合雌激素组、红曲组、模型组、假手术组,每组10只。前三组行完整双侧卵巢摘除术,假手术组仅打开腹腔,...目的:明确红曲对去卵巢大鼠骨质疏松模型血清ALP,TRAP及骨组织TNF-α,RANK表达的影响。方法:取12周龄Wistar雌性大鼠40只,随机分为结合雌激素组、红曲组、模型组、假手术组,每组10只。前三组行完整双侧卵巢摘除术,假手术组仅打开腹腔,不切除卵巢。灌胃12周后,处死各组动物,采用多光谱成像系统检测骨密度,用ELISA法测定各组大鼠血清中ALP及TRAP,用Image Pro Plus对免疫组化染色图像结果进行定量分析。结果:红曲组TNF-α免疫组化表达水平低于模型组(P<0.05),红曲组RANK免疫组化表达水平低于模型组(P<0.05)。结论:红曲可以提高血清ALP表达水平,降低血清TRAP表达水平,能够通过降低TNF-α水平及RANK水平来提高去卵巢大鼠骨密度,其机理与雌激素类似,可能与成骨细胞及破骨细胞活跃程度有关。展开更多

Therefore, improvement in endothelial function is of essential importance in the prevention of ASCVD. Red yeast rice(RYR), a healthy traditional Chinese food, has a lipid modulation function and also plays a vital role in the improvement of endothelial reactivity and cardiovascular protection; thus, it is significant in the prevention and treatment of ASCVD. This article reviews the molecular mechanisms of RYR and its related products in the improvement of endothelial function in terms of endothelial reactivity, anti-apoptosis of endothelial progenitor cells, oxidative stress alleviation and anti-inflammation.展开更多
