摘要:

文题释义:
二至丸:明代名医王三才在其著作《医便》中第一次记载了补益肝肾,滋阴止血的二至丸,该方由女贞子及墨旱莲配伍而成。

背景:研究表明二至丸可改善去势大鼠的骨密度、骨影区、骨矿物质含量以及血清雌二醇水平,但未对其可能的机制进行探讨。
目的:二至丸干预去势骨质疏松雌性模型大鼠的骨重建特点。
方法:建立绝经后骨质疏松症大鼠模型,采用6,9,12 g/(kg·d)二至丸提取物灌胃,灌胃每日1次。各组于术后第13周开始给药,分别于第16,20,24周取材。通过苏木精-伊红染色观察骨组织形态,Motic 6.0光镜图像分析系统测量骨小梁百分比,骨密度仪测定大鼠右侧胫骨骨密度,采用qPCR检测第一腰椎骨组织中骨保护素、细胞核因子κB受体活化因子配体、抗酒石酸酸性磷酸酶和骨钙素 mRNA表达水平。
结果与结论:相对同期模型大鼠,各剂量二至丸组大鼠的骨小梁形态结构较好,骨小梁数量、骨密度及骨组织骨保护素水平增加,而骨钙素、细胞核因子κB受体活化因子配体、抗酒石酸酸性磷酸酶mRNA水平降低(P < 0.05),并均呈剂量依赖性。上述数据证实,二至丸醇提物可通过改善去势大鼠高转化型骨质疏松状态,促进骨保护素表达,同时抑制细胞核因子κB受体活化因子配体表达进,而发挥到抑制破骨细胞活性的作用,最终促进去势骨质疏松雌性模型大鼠的骨重建。

Abstract: BACKGROUND: Some studies have shown that Erzhi Pill can improve the bone density, bone shadow area, bone mineral content and serum estradiol level of ovariectomized rats, but the possible mechanism has not been explored.
OBJECTIVE: To investigate the effect of Erzhi Pill on bone remodeling in an ovariectomized rat model of osteoporosis.
METHODS: A rat model of post-menopausal osteoporosis was established, and the extracts of Erzhi Pills of 6, 9, and 12 g/kg per day were administered intragastrically. Administration in each group began at the 13th week after surgery, and the samples were taken at 16, 20, and 24 weeks after surgery. The bone tissue morphology was observed by hematoxylin-eosin staining, the percentage of trabecular bone was measured by Motic 6.0 system, and the bone density of the rat right tibial bone was detected by a bone densitometer. Expressions of osteoprotegerin, nuclear factor κB receptor activating factor ligand (RANKL), tartrate-resistant acid phosphatase (TRAP) and osteocalcin mRNAs in the first lumbar vertebrae were detected by qPCR.  

RESULTS AND CONCLUSION: The trabecular bone had a better morphological structure, and the number of trabeculae, bone miner density, and bone tissue osteoprotegerin level were significantly increased in a dose-depended manner after treatment with Erzhi Pill, whereas the mRNA levels of RANKL and TRAP decreased in a dose-depended manner after treatment with Erzhi Pill (P < 0.05). Therefore, the alcohol extract of Erzhi Pill can improve the status of high-transformation osteoporosis in ovariectomized rats, promote the expression of osteoprotegerin and inhibit the expression of RANKL, so as to inhibit the activity of osteoclasts and ultimately improve the bone remodeling in female osteoporotic rats.
