摘要:


文题释义:

激素性股骨头坏死:长期或大剂量应用糖皮质激素,致使股骨头内血供受损,骨细胞变性坏死,最终发展为股骨头塌陷变形,被公认为是非创伤性股骨头坏死最主要的病因。
骨痹通消颗粒:安徽省中医院周正新教授总结国家级名老中医丁锷教授临床治疗股骨头坏死的经验及学说思想,在骨蚀宁方基础上祛除虫类药物,降低毒副作用,增加活血化瘀及补肾壮骨药物研制出治疗股骨头坏死的协定方。


背景:研究发现,糖皮质激素可抑制甲状旁腺素1受体(parathyroid hormone typeⅠreceptor,PTH1R)/蛋白激酶A(protein kinase A,PKA)信号轴中关键基因表达,干扰骨髓间充质干细胞向成骨、成血管方向分化,导致骨内血供、骨组织结构的破坏。课题组前期研究结果表明骨痹通消颗粒可诱导血管形成、抑制成骨细胞凋亡,对激素性股骨头坏死具有一定的防治作用,其机制尚未明确。

目的:观察骨痹通消颗粒对激素性股骨头坏死模型小鼠的治疗效果,从PTH1R/PKA信号轴探讨其作用机制。
方法:采取腹腔注射脂多糖和臀肌注射醋酸泼尼松龙建立激素性股骨头坏死模型,将造模成功的60只C57小鼠随机分成模型组、骨痹通消颗粒组和通络生骨胶囊组,每组20只,另选取12只健康小鼠作为正常对照组,分别灌胃相应药物12周后,苏木精-伊红染色观察股骨头组织形态学变化,酶联免疫吸附测定法检测血清中骨碱性磷酸酶、Ⅰ型氨基端延长肽、甲状旁腺激素、骨钙素、碱性磷酸酶水平,Western blot和RT-qPCR法检测股骨头组织中PTH1R、PKA、MEF2、SOST、GNAS的蛋白及基因表达水平。

结果与结论:骨痹通消颗粒可能通过降低小鼠血清甲状旁腺激素水平,抑制PTH1R/PKA信号轴的激活,进一步上调SOST、MEF2的表达,提高骨碱性磷酸酶、Ⅰ型氨基端延长肽、骨钙素、碱性磷酸酶水平,从而改善股骨头坏死情况,与通络生骨胶囊干预效果相当,推测骨痹通消颗粒可能通过调节PTH1R/PKA信号轴发挥防治激素性股骨头坏死的作用。

Abstract: BACKGROUND:  Glucocorticoids can inhibit the expression of hub genes in the parathyroid hormone type I receptor (PTH1R)/protein kinase A (PKA) signaling axis and interfere with the osteogenic and angiogenic differentiation of bone marrow mesenchymal stem cells, leading to the disruption of blood supply in bone and bone tissue structures. Previous studies of the research team showed that Gubitongxiao granules can induce blood vessel formation and inhibit osteoblast apoptosis, which has a certain effect on the prevention and treatment of steroid-induced femoral head necrosis.
OBJECTIVE: To observe the therapeutic effect of Gubitongxiao granules in a mouse model of steroid-induced femoral head necrosis, and to explore its mechanism from the PTH1R/PKA signaling axis. 
METHODS: An animal model of steroid-induced necrosis of the femoral head was established by intraperitoneal injection of lipopolysaccharide and gluteal muscle injection of prednisolone acetate. After identification by nuclear magnetic resonance method, 60 mice that were successfully modeled were divided into model group, Gubitongxiao granule group and Tongluo Shenggu capsule group, with 20 mice in each group. Another 12 normal mice were used as control group. The corresponding groups were intragastrically given the corresponding drugs for 12 weeks, and then the samples were taken under anesthesia. Histomorphology of femoral head samples was observed by hematoxylin-eosin staining. Enzyme-linked immunosorbent assay was used to detect the serum levels of bone alkaline phosphatase, type I amino-terminal extension peptide, parathyroid hormone, osteocalcin and alkaline phosphatase. Western blot and RT-qPCR were used to detect PTH1R, PKA, myocyte enhancer factor 2, sclerostin and guanylate-binding protein activity-stimulating peptide at protein and gene expression levels, respectively. 
RESULTS AND CONCLUSION: Gubitongxiao granules may reduce the serum PTH level in mice, inhibit the activation of the PTH1R/PKA signal axis, further up-regulate the protein expressions of sclerostin and myocyte enhancer factor 2, and increase the levels of bone alkaline phosphatase, type I amino-terminal extension peptide, osteocalcin and alkaline phosphatase in mice, thus improving femoral head necrosis, which is comparable to the intervention effect of Tongluo Shenggu capsules. It is speculated that Gubitongxiao granules may prevent and treating hormonal femoral head necrosis by regulating the PTH1R/PKA signaling axis.

Key words: Gubitongxiao granule, Tongluo Shenggu capsule, steroid-induced necrosis of the femoral head, PTH1R, PKA, parathyroid hormone
