摘要:


文题释义:

安石榴苷:石榴中最丰富、活性最高的一种较大的多酚化合物,能通过降低氧化应激、炎症反应和细胞凋亡对肝、肾、神经系统等发挥保护作用,已有研究表明安石榴苷对阿尔茨海默病、心血管疾病、癌症等老年性常见病有一定的治疗效果。
绝经后骨质疏松:是最常见的骨质疏松症类型,绝经期雌激素缺乏导致骨代谢增加,骨吸收超过骨形成,随着时间的推移最终出现骨质疏松,以骨密度降低、骨微结构破坏、骨强度受损和骨折风险增高为特征。


背景:安石榴苷作用广泛,安全性高,但其对成骨细胞和绝经后骨质疏松症的作用尚不清楚。

目的:探讨安石榴苷对成骨细胞和绝经后骨质疏松症的作用。
方法:安石榴苷作用于MC3T3-E1细胞,检测其促成骨细胞增殖作用。在成骨诱导液中添加安石榴苷,检测其促成骨分化作用。卵巢切除大鼠术后灌胃安石榴苷,3个月后进行Micro CT扫描和血清1型前胶原氨基末端肽检测,观察治疗效果。

结果与结论:①CCK-8检测发现安石榴苷能促进成骨细胞增殖(P < 0.05);②qRT-PCR和Western blot检测发现安石榴苷能促进碱性磷酸酶、Runx2 mRNA和蛋白的表达(P < 0.05);③Micro CT扫描和血清学检测结果显示,安石榴苷能改善卵巢切除大鼠的骨密度、骨体积分数、骨小梁厚度、骨小梁数目和1型前胶原氨基末端肽水平;④结果表明,安石榴苷能促进成骨细胞增殖和分化,且对绝经后骨质疏松大鼠有治疗作用。

Abstract: BACKGROUND: Punicalagin has a wide range of effects and high safety, but its effect on osteoblasts and postmenopausal osteoporosis is unknown.
OBJECTIVE: To investigate the effect of punicalagin on osteoblasts and postmenopausal osteoporosis.
METHODS: The effect of punicalagin on the proliferation of MC3T3-E1 cells was detected. Punicalagin was added to the osteogenic induction medium to detect its effect on osteogenic differentiation. Punicalagin was used to treat ovariectomized rats and Micro CT scan and serum procollagen type 1 N-terminal propeptide test were performed after 3 months to detect the therapeutic effect.
RESULTS AND CONCLUSION: Cell counting kit-8 assay showed that punicalagin could promote the proliferation of osteoblasts (P < 0.05). The results of qRT-PCR and western blot showed that punicalagin could promote the mRNA and protein expressions of alkaline phosphatase and Runx2 in osteoblasts (P < 0.05). The results of Micro CT scan and serological test showed that punicalagin could improve bone mineral density, bone volume fraction, trabecular thickness, trabecular number and procollagen type 1 N-terminal propeptide level of ovariectomized rats. To conclude, punicalagin can promote osteoblast proliferation and differentiation, and have therapeutic effects in postmenopausal osteoporosis rats.

Key words: punicalagin, postmenopausal osteoporosis, ovariectomy, osteoblast, procollagen type 1 N-terminal propeptide
