Large amounts of experimental and animal evidence have confirmed that iron accumulation is associated with bone loss. However, it is still lack of the clinical studies relating iron accumulation to bone loss, especially in the pathological conditions during our Chinese. In this study, the investigators aim to assess the association between the levels of serum ferritin and bone mineral density in Chinese healthy postmenopausal women.
The aim of this study is the quantitative determination of bone-specific microRNAs in the serum of postmenopausal women with osteoporosis during antiresorptive or osteoanabolic therapy.
The purpose of this study is to determine the effects of Moringa Oleifera on the structure and function of bone in post-menopausal women ingesting 1000 mg of Moringa Oleifera daily for 12 weeks.
For nearly 112 million patients with osteoporosis in China, it is of great significance for preventing and treating by clearly understanding the molecular mechanism of kidney deficiency. Thus, the research group has demonstrated in the earlier research that CLCF1 is an associated gene that can regulate JAK2/STAT3 signal pathway and impact bone metabolism for kidney yin deficiency of postmenopausal osteoporosis (PMOP). To make clear understanding of the direct-acting mechanism of CLCF1 for bone metabolism, this study intends to: ①observe impacts of low expression of CLCF1 upon immunities in mice and OPG/RANKL/RANK signal system using the technology of adenovirus associated virus. ②explore impacts of over-expression and silencing of CLCF1 on B lymphocytes by culcuturing the cells together with osteoblasts. ③ analyze the impacts of treating kidney yin deficiency of PMOP by Liuwei Dihuang pill upon immunities and OPG/RANKL/RANK system, and discuss the mechanism of regulating bone metabolism by CLCF1 by OPG/RANKL/RANK system via the bridge between immune system and bone metabolism, so as to demonstrate if the hypothesis of this study that "the molecular osteoimmunological mechanism of kidney yin deficiency of postmenopausal osteoporosis (PMOP) is possibly closely related to the impacts of CLCF1 regulation of OPG/RANKL/RANK signal system on bone metabolism" is right or not.
In 2006, Weinberg proposed a hypothesis that iron accumulation was a risk factor for osteoporosis. Osteoporosis is a common complication in various diseases, such as hemochromatosis, African hemosiderosis, thalassemia, and sickle cell disease, which all share iron accumulation as a common denominator. Moreover, a 3-year retrospective longitudinal study has shown that iron accumulation was also associated with osteoporosis in healthy adults and especially that it can increase the risk of fractures in postmenopausal women. Based on these observations, iron chelation therapy may have a promising future in the treatment of iron accumulation-related osteoporosis by removing iron from the body. The purpose of this study is to determine whether the addition of the iron chelator, deferasirox, to standard therapy for postmenopausal osteoporosis, is safe and effective.
Postmenopausal women often seek non-pharmacologic interventions for the protection of bone health. Previous research in humans and rodents has indicated that dietary dried plum consumption may be beneficial for bone health, especially in postmenopausal women. However, it is unknown in what quantity dried plums need to be consumed to be of benefit and through what mechanisms dried plums act to impact bone health. Therefore, the purpose of this study is to evaluate the impact of 52 weeks of dried plums consumption in varying quantities on bone mineral density (BMD), bone geometry, and estimated bone strength in postmenopausal women. The investigators also seek to evaluate the mechanisms underlying the effects of dried plums as a dietary supplement by assessing polyphenols and the bioavailable conjugated metabolites in the urine of postmenopausal women taking different doses of dietary dried plums. The investigators aim to further investigate the mechanisms of dried plum action on bone by measuring markers of bone metabolism in response to dried plum consumption.
A multicenter, randomized, double-blind, placebo-controlled study to evaluate the effect of 6 months treatment with Romosozumab compared to placebo by determining the percent changes in bone mineral density
This study will investigate participant satisfaction (including compliance, preference, tolerability) with once-monthly Bonviva in women with post-menopausal osteoporosis or osteopenia transitioned from once-weekly alendronate or risedronate. The anticipated time on study treatment is 6 months, and the target sample size is 1776 individuals.
The purpose of this study is to evaluate treatment adherence to different regimens of ibandronate in postmenopausal women with osteoporosis or osteopenia who are intolerant to daily or weekly alendronate or risedronate therapy due to gastrointestinal (GI) side effects. The anticipated time on study treatment is 12 months, and the target sample size is 517 individuals.
This study will evaluate participant-reported preference for either ibandronate or a comparator drug in women with postmenopausal osteoporosis. The anticipated time of study treatment is 6 months, and the target sample size is 338 individuals.
