RESUMO

Background: Osteoporosis poses a significant health challenge characterized by reduced bone density and increased fracture risk. Percutaneous kyphoplasty, a common treatment, aims to stabilize vertebral fractures. However, adjunctive therapies like zoledronic acid remain underexplored in improving postoperative outcomes and bone health in these patients. Objective: This study aims to evaluate the efficacy of zoledronic acid combined with calcium carbonate and vitamin D3 in treating osteoporosis, providing valuable clinical insights. Methods: A cohort of sixty-six osteoporosis patients who underwent percutaneous kyphoplasty and received subsequent treatment at our hospital between March 2020 and March 2022 were selected. Thirty-three patients received calcium carbonate and vitamin D3 (control group), while the remaining thirty-three patients were treated with zoledronic acid alongside calcium carbonate and vitamin D3 (research group). Pre- and post-treatment assessments included bone mineral density measurements, bone metabolism and turnover marker evaluations, symptom improvement assessments using the Visual Analogue Scale (VAS) and the Oswestry Disability Index (ODI), monitoring of adverse reactions, and assessment of quality of life using the Core Quality of Life questionnaire (QOL-C30). A one-year follow-up was conducted to determine re-fracture incidence. Results: Post-treatment, the research group exhibited significantly lower VAS, ODI, tartrate-resistant acid phosphatase-5b, and osteocalcin levels compared to the control group, while bone alkaline phosphatase levels were higher (P < .05). There was no significant difference in adverse reaction incidence between the groups (P > .05), but the research group demonstrated higher QOL-C30 scores (P < .05). Follow-up analysis revealed no notable difference in re-fracture rates between the groups (P > .05). Conclusions: Zoledronic acid in combination with calcium carbonate and vitamin D3 effectively enhances bone health in osteoporosis patients, warranting its clinical recommendation. This regimen shows promise for improving patient outcomes in osteoporosis management.

RESUMO

Osteoporosis (OP) is a systemic metabolic skeletal disorder characterized by a decline in bone mass, bone mineral density, and deterioration of bone microstructure. It is prevalent among the elderly, particularly postmenopausal women, and poses a substantial burden to patients and society due to the high incidence of fragility fractures. Kidney-tonifying Traditional Chinese medicine (TCM) has long been utilized for OP prevention and treatment. In contrast to conventional approaches such as hormone replacement therapy, TCM offers distinct advantages such as minimal side effects, low toxicity, excellent tolerability, and suitability for long-term administration. Extensive experimental evidence supports the efficacy of kidney-tonifying TCM, exemplified by formulations based on the renowned herb Cornus officinalis and its bioactive constituents, including morroniside, sweroside, flavonol kaempferol, Cornuside I, in OP treatment. In this review, we provide a comprehensive elucidation of the underlying pathological principles governing OP, with particular emphasis on bone marrow mesenchymal stem cells, the homeostasis of osteogenic and osteoclastic, and the regulation of vascular and immune systems, all of which critically influence bone homeostasis. Furthermore, the therapeutic mechanisms of Cornus officinalis-based TCM formulations and Cornus officinalis-derived active constituents are discussed. In conclusion, this review aims to enhance understanding of the pharmacological mechanisms responsible for the anti-OP effects of kidney-tonifying TCM, specifically focusing on Cornus officinalis, and seeks to explore more efficacious and safer treatment strategies for OP.

RESUMO

OBJECTIVE: To explore the effect of arterial perfusion of marrow multifunctional stem cells (MFSC) in treating femoral head necrosis and its mechanism. METHODS: The rabbit model of femoral head necrosis was established by large dose of methyl-prednisone through Shwartzman response. Bone marrow was extracted from femoral bone of model rabbit and isolated in vitro for culturing and proliferating MFSC. The experimental rabbits were randomly divided into 4 groups, treated with normal saline (A), Salvia + urokinase (B), MFSC (C) and MFSC + Salvia + urokinase (D), respectively, they were sacrificed in batches at 2 and 4 weeks after treatment, and changes in various parameters, including molybdenum target roentgenogram, routine pathology with HE staining, tetracycline labeled fluorescent microscopy and ultrastructure alteration by scanning electron microscope (SEM), were observed. RESULTS: Typical appearance of femoral head necrosis was shown in the successfully modeled rabbits. Two and 4 weeks after treatment by high selective drug via medial and lateral femoral circumflex arterial perfusion, the X-ray examination showed significant improvement of bone density; pathohistologic manifestation showed decrease of empty bone lacuna, increase of osteoblast and new bone formation; tetracycline fluorescent labeled microscopic picture showed bright fluorescent band of increased osteoblasts in necrosis repairing region with widened border; SEM displayed irregularly arranged fibrosis in necrosis region, abundant organelles in osteoblasts with few empty bone lacuna. The above-mentioned improvement was more significant in rabbits treated by MFSC. CONCLUSION: High selective femoral drug arterial perfusion in treating femoral head necrosis could accelerate the process of revascularization and re-ossification in rabbits. As compared with Salvia, MFSC showed quicker and more potent effect.
