绝经后骨质疏松症已成为一个全球性的公共卫生问题。本研究的目的是探讨中药小药丸对这种情况的治疗效果和相关机制。
骨质疏松症是老年人和绝经后妇女常见的代谢性疾病,早期无明显症状。在这种情况的后期,患者容易发生骨折,这会严重影响他们的健康和生活质量。全球预期寿命的增加使骨质疏松症成为全球关注的问题。逍遥丹之前
用于治疗抑郁症。此外,该药物似乎具有雌激素样活性,这会影响早期成骨细胞特异性标志物 ALP 和骨细胞外基质主要成分 COL-1 的表达。评估小药丸对小鼠绝经后骨质疏松症 (PMOM) 的影响。通过中医系统药理学 (TCMSP) 数据库获取逍遥丸中各草药成分的靶点信息。利用来自 GeneCards 、 OMIM 、 PharmGkb 、 TTD 、 DrugBank 等网站的信息,通过 Cytoscape 和 String 网络构建草药复合物的调控网络,以评估蛋白质相互作用。对小鼠进行卵巢切除,并用高剂量和低剂量的逍遥丸治疗,并将其与对照组进行比较。通过骨组织的免疫细胞化学评估他们的症状。结果表明,逍遥丸具有通过 IL-17 信号通路缓解去卵巢小鼠 PMOM 症状的能力。这种药物有可能成为治疗骨质疏松症的新型治疗剂。
世界卫生组织 (WHO) 将骨质疏松症 (OP) 定义为一种以骨量减少和骨组织微结构恶化为特征,导致骨脆性增加,从而增加骨折风险的疾病1。骨质疏松症的临床意义在于它可导致骨折,这与高死亡率、发病率和经济成本有关2。绝经后骨质疏松症 (PMOP) 是由绝经后女性雌激素水平降低引起的,导致破骨细胞活性增加,导致骨质流失和骨微结构破坏。这通常会导致骨质疏松症,对健康产生严重影响3。目前的 PMOP 疗法包括雌激素替代疗法、双膦酸盐和甲状旁腺激素,但它们可能具有不同程度的不良反应、长期依从性不足和高成本4。因此,负担得起的草药对于很大一部分人来说是一种可行的选择。
逍遥丸被列入中国药典5,其中含有八种草药成分,包括柴胡、当归、白芍、白术、茯苓、薄荷草、甘草和新鲜生姜。众所周知,所有这些草药都能有效解肝健脾、养血、调节月经周期,该混合物也用于治疗抑郁症6。然而,逍遥丸在骨质疏松症中的作用尚不清楚。
早期研究表明,炎症会导致骨质流失
游江民族医科大学实验动物伦理委员会批准了该研究方案(批准文号:2022101502)。雌性 C57BL/6 小鼠,10-12 周龄,SPF 级和体重 (22 ± 2) g,饲养在游江民族医科大学 SPF 级动物实验中心。实验动物维持在 24-26 °C 的温度和 55% 至 60% 的相对湿度下。

逍遥丸的活性成分和作用靶点
通过检索 TCMSP 数据库并根据口服生物利用度 (OB) ≥ 30% 和类药性质 (DL) ≥ 0.18 的标准进行筛选,发现小药丸中存在 125 种活性成分。其中,成分 6、4、9、13、2、6、83 和 2 分别来自白芍、白术、薄荷、柴胡、当归、茯苓、甘草和生姜。一些活性成分如表 1 所示。此外,从 TCMSP 数据库中共获得 879 个有?.......
据统计,骨质疏松症在美国每年导致 150 万例骨折,其中绝大多数发生在绝经后妇女身上 27。随着人口老龄化的增加,预计全球未来大部分髋部骨折将发生在亚洲,到 2050 年,全球髋部骨折总数将达到 820 万例28。预防骨折的成本几乎等于治疗骨折的成本,使用药物不可避免地会产生一些副作用29。因此,迫切需要一种更具成本效益的方法,在?.......
