Aims Osteogenesis imperfecta (OI) is a group of inheritable connective tissue diseases characterized by frequent fractures and reduced bone mass.Blue sclerae,dentinogenesis imperfecta,hearing and sight impairment,muscle weakness and joint laxity are frequently existed in OI patients.OI genetic heterogeneity is obvious and autosomal dominant form is the primary inheritance pattern,which is caused by mutations of COL1A1 or COL1A2 genes that encode the proa 1 and proa2 chains of type Ⅰ procollagen.Theres little report about the mutation spectrum of OI patients in China.The study aims to investigate the epidemiology of OI in China.

目的 通过动物实验探讨丹参素单体对醋酸泼尼松所致骨丢失的预防作用及其浓度效应.方法 采用醋酸泼尼松(6mg/kg/d)连续灌胃14周建立动物模型,并同时采用丹参素和罗盖全(阳性对照)灌胃给药进行干预.实验结束后,取肾上腺、胸腺、子宫、卵巢、胫前肌等组织称重并记录重量;取左侧股骨和第五腰椎,进行骨密度检测;取左侧胫骨进行Micro-CT扫描,观察松质骨骨微结构及检测相关参数.结果 与空白对照组比较,
目的 糖皮质激素性骨质疏松症(GIOP)是最常见的继发性骨质疏松症,维生素D是GIOP的基础治疗药,主要通过维生素D受体(VDR)发挥作用.本研究拟从整体动物水平,研究不同作用时间的地塞米松(Dex)对大鼠骨量、骨组织VDR和血清25(OH)D3的影响,旨在探讨GIOP的发病与25(OH)D3、VDR的关系,为防治GIOP提供实验依据.方法 将40只3.5月龄的SD雌性大鼠,随机分为Dex组和对照

目的 观察老龄雄性ApoE基因敲除小鼠的骨微结构和骨代谢,并初步探讨Sirt1在骨衰老过程中的作用机制.方法 入组18月龄雄性ApoE基因敲除小鼠各8只以及同性别、同周龄的C57bl/6野生型小鼠12只.应用Micro-CT(Skyscan 1176)检测分析小鼠股骨骨密度及骨微结构,并检测血骨代谢指标,行骨组织学检查.并检测胫骨Sirt1及Runx2的mRNA和蛋白的表达.结果 1、ApoE基因
目的 调查医务人员中骨密度及体质指数分布情况及其相关性,提高医务人员对自身健康的重视度.方法 收集2014年度本院40-90岁职工健康体检数据,包括性别、年龄、身高、体质量,体质指数(BMI),空腹血糖、胆固醇(TC)、甘油三脂(TG)、低密度脂蛋白(LDL-C)、高密度脂蛋白(HDL-C)).记录腰椎、股骨颈、大转子,粗隆间及Ward区骨密度值、T值、Z值(DEXA方法).采用SPSS17.0软
目的 国外研究发现,老年男性、围绝经期和绝经后妇女人群的高血尿酸水平与骨密度(bone mineral density,BMD)增高有关,但这种关联尚未在一般人群和不同种族得到验证,也无数据支持尿酸是BMD变化的直接影响因素.我们使用孟德尔随机化分析的方法检验在中国上海地区汉族老年人群尿酸对BMD是否具有因果关联,以期揭示尿酸增高是否对骨质疏松具有保护作用.方法 我们选取1362名来自上海社区人群
目的 观察可注射型人工骨为充填材料的经皮后凸成形术(PKP)治疗骨质疏松性胸腰椎压缩骨折的初步疗效.方法 采用PKP的方法,使用可注射型人工骨(吉莱骨粉)为充填材料,在C形臂X线透视下,经单侧或双侧椎弓根穿刺途径的PKP治疗22例(29个椎体)骨质疏松性胸腰椎压缩骨折的椎体.20例患者经双能X线骨密度仪测量,T值为-2.5-4.5.其中单椎体压缩骨折19例,多椎体压缩骨折3例;胸椎11个,腰椎18
