目的观察槲皮素对双膦酸盐类治疗老年性骨质疏松患者骨代谢指标的影响。方法 216例老年性骨质疏松患者(收治时间:2017年1月至2018年1月)以信封随机分组法分为常规对照组(共108例,双膦酸盐+骨健康补充剂治疗6个月)和槲皮补充组(共108例,以双膦酸盐+骨健康补充剂+槲皮素治疗6个月)。分析常规对照组和槲皮补充组的主客观疗效(总有效率、ODI评分、SF-36评分及VAS视觉评分)、骨密度及骨代谢指标(CTX-1、BALP、BGP、t PINP、PTH)的差异。结果与治疗前比较,槲皮补充组和常规对照组治疗后的前臂远端骨密度、BALP及SF-36评分均提升,而VAS评分、ODI评分、PTH、BGP、CTX-1、t PINP均下降(P均0.05),但槲皮补充组前臂远端骨密度、BALP及SF-36评分的升幅更大,VAS评分、ODI评分、PTH、BGP、CTX-1、t PINP的降幅更大。槲皮补充组临床总有效率(87.04%)显著优于常规对照组(68.52%)(P0.05)。结论补充槲皮素辅助双膦酸盐治疗老年性骨质疏松患者,可显著改善患者骨密度指标、疼痛症状、功能障碍情况及骨代谢指标的异常表达,提升患者生活质量。 相似文献

BACKGROUND: The pathogenesis of knee intraarticular adhesion is yet unknown. Excessive proliferation of fibroblasts is considered to cause knee intraarticular adhesion.
OBJECTIVE: To study the preventive effects of methotrexate on knee intraarticular adhesion through fibroblast apoptosis induced by endoplasmic reticulum stress.
METHODS: The viability of the cultured fibroblasts treated with methotrexate (10-5-10-9mol/L) or PBS was determined after 24 hours. Fibroblast apoptosis was detected by Hoechst33342 staining. Endoplasmic reticulum stress- and apoptosis-related proteins, including cleaved-PARP, CHOP, Bax and Bcl-2, were determined by western blot assay. Eighteen healthy male New Zealand white rabbits were used to establish the knee intraarticular adhesion models, and equally randomized into three groups, and received topical application of 2 or 1 g/L methotrexate, or normal saline (control). The preventive effects of methotrexate on knee intraarticular adhesion and CHOP expression in scar tissue were observed.
RESULTS AND CONCLUSION: Methotrexate inhibited the proliferation and viability of fibroblasts in a dose-dependent manner. The number of apoptotic fibroblasts was significantly increased compared with control group. Protein expression of cleaved-PARP, CHOP, and bax was increased, while protein expression of bcl-2 was decreased with time. The animal experiment showed that preventive effects of 2 g/L methotrexate on knee intraarticular adhesion were superior to 1 g/L methotrexate treatment. CHOP expression in the scar tissue in the methotrexate groups was higher than the control group and that was higher in high-dose methotrexate group. Our results suggest that methotrexate prevents knee intraarticular adhesion via endoplasmic reticulum stress-induced fibroblast apoptosis.
