    摘要:

    目的 通过 LC/ MS 分析技术和网络药理学的综合策略,结合实验验证探讨补肾壮骨汤治疗 2型糖尿病性骨质疏松(T2DOP)的有效成分和作用机制。 方法 采用 UPLC-Q-Orbitrap-MS 法对补肾壮骨汤中的有效化学成分进行分析鉴定,检索数据库中 T2DOP 与铁死亡的相关基因,取交集得到有效成分通过调控铁死亡途径治疗 T2DOP 的潜在靶点。 腹腔注射链脲佐菌素联合高糖高脂喂养诱导的 T2DOP 大鼠模型,模型构建成功后进行补肾壮骨汤灌胃 8 周,检测体质量、血糖及糖化血红蛋白,取材后进行 Micro CT 以获取骨形态学变化,试剂盒检测总铁离子水平、SOD 及 MDA 水平。 Western blot 法检测骨组织 Nrf2 / HO-1 信号及铁死亡相关蛋白表达。 结果 补肾壮骨汤中药入血化合物共预测到 46 种已识别化合物的 848 个靶点。 通过比对GeneCards、CTD 数据库和 FerrDb V2 数据库最终获得 81 个补肾壮骨汤可能通过调控铁死亡抗 T2DOP 的潜在靶点。 PPI 网络分析 SIRT1、MTOR、STAT3、Nrf2、SRC、EGFR、IL-6、MAPK3、IL-1B、PPARG、ALB 等节点可能是补肾壮骨汤治疗 T2DOP 的重要靶点。 KEGG 通路富集分析得到关于交集靶基因的 134 条信号通路,主要通路为代谢途径、脂质与动脉粥样硬化、糖尿病并发症中的铁死亡信号通路等。 与对照组相比,模型组大鼠体质量增长缓慢,血糖及糖化血红蛋白水平升高,骨小梁发生破坏,骨密度、骨体积分数、骨小梁厚度及密度下降,骨小梁分离度升高,骨组织总铁离子及 MDA 水平上升,SOD 活力下降,Nrf2、HO-1 及铁死亡相关蛋白表达上升(P<0. 05);与模型组相比,补肾壮骨汤干预后大鼠体质量增长有所上升,血糖及糖化血红蛋白水平有所下降,骨小梁破坏减轻,骨密度、骨体积分数、骨小梁数目及密度增加,骨组织总铁离子及 MDA 水平下降,SOD 活力有所提升,Nrf2、HO-1 及铁死亡相关蛋白表达下降(P<0. 05)。 结论 补肾壮骨汤治疗 T2DOP 具有多成分、多靶点、多途径的特点,体内实验结果显示补肾壮骨汤可通过调控 Nrf2 / HO-1 信号通路,抑制氧化应激和铁死亡防治 T2DOP。

    Abstract:

    Objective To identify the effective components and mechanism of Bushen Zhuanggu Tang for the treatment of type 2 diabetic osteoporosis (T2DOP) using a comprehensive strategy including liquid chromatography /mass spectrometry (LC/ MS) and network pharmacology, combined with experimental verification. Methods The effective chemical components in Bushen Zhuanggu Tang were analyzed and identified by ultra-high-performance LCQ-Orbitrap-MS. Genes related to T2DOP and ferroptosis were retrieved from the database, and the intersection was obtained to identify potential targets of the active ingredients for the treatment of T2DOP by regulating the ferroptosis pathway. A T2DOP rat model was induced by intraperitoneal injection of streptozotocin combined with high-sugar and high-fat feeding, and the rats were then administered Bushen Zhuanggu Tang for 8 weeks. Body weight, blood glucose, and glycosylated hemoglobin were measured. Bone morphological changes were detected by Micro CT. Total iron ion, superoxide dismutase (SOD), and malondialdehyde (MDA) levels were detected using appropriate kits.Nuclear factor erythroid 2-related factor 2 ( Nrf2) / heme oxygenase-1 ( HO-1) signaling- and ferroptosis-related proteins in bone tissue were detected by Western blot. Results A total of 848 targets of 46 identified compounds were predicted in the blood compounds of Bushen Zhuanggu Tang. Comparing the GeneCards, Comparative Toxicogenomics, and FerrDb V2 databases finally indicated 81 potential targets of Bushen Zhuanggu Tang against T2DOP by regulating ferroptosis. Protein-protein interaction network analysis indicated that silent information regulator1, mammalian target of rapamycin, signal transducer and activator of transcription 3, Nrf2, SRC, epidermal growth factor receptor, interleukin ( IL)-6, mitogen-activated protein kinase-3, IL-1B, peroxisome proliferator-activated receptor γ, albumin, and other nodes may be important targets for Bushen Zhuanggu Tang in the treatment of T2DOP.Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis identified 134 signaling pathways related to the intersection target genes. The main pathways were metabolic pathways, lipid and atherosclerosis, and ferroptosis signaling pathways in diabetic complications. The in vivo experiments showed that the body weight of rats in the Model group increased slowly compared with the Control group, while blood glucose and glycosylated hemoglobin levels increased, trabecular bone was destroyed, bone mineral density, bone volume fraction, and trabecular thickness and density decreased, the degree of trabecular separation increased, total iron ion and MDA levels in bone tissue increased, SOD activity decreased, and Nrf2, HO-1, and ferroptosis-related protein levels increased (P<0. 05).Compared with the Model group, weight gain increased, blood glucose and glycosylated hemoglobin levels decreased,destruction of the bone trabecula decreased, bone mineral density, bone volume fraction, and bone trabecula number and density increased, total iron ion and MDA levels in bone tissue decreased, while SOD activity increased, and Nrf2, HO-1, and ferroptosis-related protein levels decreased (P<0. 05). Conclusions Bushen Zhuanggu Tang has multi-component, multi-target, and multi-pathway characteristics for the treatment of T2DOP. The result of in vivo experiments show that Bushen Zhuanggu Tang can prevent and treat T2DOP by regulating the Nrf2 / HO-1 signaling pathway and inhibiting oxidative stress and ferroptosis.
