近日，华西基础医学与法医学院刘肖珩教授团队在Bone Research发表原创研究论文，证实了基质囊泡来源的AnxA5在骨重塑中的重要作用，阐明了AnxA5通过促进基质囊泡与I型胶原的黏附，诱导骨前体细胞发生自噬和加速矿化预防骨丢失的新机制，为骨质疏松症的防治提供新策略。
Bone mineral density during pregnancy in women participating in a randomized controlled trial of vitamin D supplementation
bone mineral content bone mineral density cholecalciferol pregnancy vitamin D
2018/11/21
Background: Little is known about bone mineral density (BMD) during pregnancy. Advances in technology with lower radiation emissions by dual-energy X-ray absorptiometry instruments now permit the safe...
Combined bioavailable isoflavones and probiotics improve bone status and estrogen metabolism in postmenopausal osteopenic women: a randomized controlled trial
isoflavone bone turnover bioavailability probiotics osteopenia postmenopause equol bone density
2018/11/16
Background: Female age-related estrogen deficiency increases the risk of osteoporosis, which can be effectively treated with the use of hormone replacement therapy. However, hormone replacement therap...
A systematic review and meta-analysis of the effects of isoflavone formulations against estrogen-deficient bone resorption in peri- and postmenopausal women

2018/11/12
Background: Bone mineral content (BMC) and bone mineral density (BMD) are positively correlated with dietary protein intakes, which account for 1–8% of BMC and BMD variances. However, the relation bet...
Free 25-hydroxyvitamin D is low in obesity, but there are no adverse associations with bone health
bone density bone turnover half-life obesity vitamin D vitamin D–binding protein
2018/11/30
Background: The mechanism and clinical significance of low circulating 25-hydroxyvitamin D [25(OH)D] in obese people are unknown. Low total 25(OH)D may be due to low vitamin D–binding proteins (DBPs) ...
Moderate weight loss in obese and overweight men preserves bone quality

骨与关节系统发生过程中相关调控机制的研究进展Progress on the related mechanism in the development of bone and joint
发生 肢芽 间充质细胞
2008/1/10
摘要脊椎动物胚胎期骨与关节系统的发生是一种复杂生命现象，起始于中胚层间充质细胞的定向聚集，形成肢芽，然后在一系列作用因子的调控下，肢芽内细胞进一步分化，形成具有骨骼雏形的软骨原基，后者经软骨内骨化发育成骨。四肢骨大多是以这种方式发生的，四肢的滑膜关节系统也随骨骼的发生而形成。详细阐述了近年来对肢体骨与关节系统发生各步骤相关调控机制方面的研究进展。Abstract: The embryonic de...
