Glucocorticoid (GC) induced osteoporosis (GIOP) is the most common form of secondary osteoporosis. It develops in a dose and time dependent manner, due to a rapid and transient increase in bone resorption, followed by the inhibition of bone formation. 相似文献
目的从基因分子水平探讨酒精性骨质疏松(alcoholic osteoporosis,AOP)大鼠的发病机制,观察生髓健骨胶囊对AOP大鼠骨密度(bone mineral density,BMD)、骨矿含量(bone mineral content,BMC)表达的影响,探讨生髓健骨胶囊对AOP大鼠模型的中药防治作用机理。方法选取成年雄性(清洁级)SD大鼠120只,称体重,随机分为4组,每组各30只,用白酒灌胃法造模,同时分别给予生理盐水、碳酸钙阿法D3、生髓健骨胶囊灌胃给药。于造模8、12、16周末取材,检测股骨上端BMD、BMC指标。结果检测造模干预8、12、16周后BMD、BMC指标变化,模型组BMD、BMC与正常组比较明显降低,且差异有统计学意义(P0.01),结果表明饮酒大鼠确实存在骨量减少,BMD、BMC降低;中药干预组BMD、BMC与模型组相比显著升高(P0.01);中药干预组BMD、BMC与西药对照组相比,明显升高(P0.05)。结论通过观察生髓健骨胶囊对AOP大鼠的实验指标,证明了生髓健骨胶囊能够提高AOP大鼠骨密度,增加骨矿含量,抑制矿物质丢失,改善大鼠的骨代谢。 相似文献
Purpose: Non-ambulatory persons with cerebral palsy are prone to low bone mineral density. In ambulatory persons with cerebral palsy, bone mineral density deficits are expected to be small or absent, but a consensus conclusion is lacking. In this systematic review bone mineral density in ambulatory persons with cerebral palsy (Gross Motor Function Classification Scales I–III) was studied.
Materials and methods: Medline, Embase, and Web of Science were searched. According to international guidelines, low bone mineral density was defined as Z-score?≤??2.0. In addition, we focused on Z-score?≤??1.0 because this may indicate a tendency towards low bone mineral density.
Results: We included 16 studies, comprising 465 patients aged 1–65?years. Moderate and conflicting evidence for low bone mineral density (Z-score?≤??2.0) was found for several body parts (total proximal femur, total body, distal femur, lumbar spine) in children with Gross Motor Function Classification Scales II and III. We found no evidence for low bone mineral density in children with Gross Motor Function Classification Scale I or adults, although there was a tendency towards low bone mineral density (Z-score?≤??1.0) for several body parts.
Conclusions: Although more high-quality research is needed, results indicate that deficits in bone mineral density are not restricted to non-ambulatory people with cerebral palsy.
Implications for Rehabilitation
Although more high-quality research is needed, including adults and fracture risk assessment, the current study indicates that deficits in bone mineral density are not restricted to non-ambulatory people with CP.
Health care professionals should be aware that optimal nutrition, supplements on indication, and an active lifestyle, preferably with weight-bearing activities, are important in ambulatory people with CP, also from a bone quality point-of-view.
If indicated, medication and fall prevention training should be prescribed.
