Objective: Osteoporotic fracture is the most severe complication of osteoporosis and vertebral column suffer the highest risk. The aim of the part I study was to evaluate the prevalence of vertebral fracture, distribution of prevalent fractures as well the grade of the fractures in community-dwelling elderly in China southern city.Methods: A population of 6142 elderly over 50 years old from four communities in China southern city was gathered voluntarily...

Objective: The bone health index (BHI) has previously been shown to be 1.5% lower in Asian children than in Caucasian children, both living in USA. The aim of this study is to present reference curves for BHI of Chinese Han children and to compare to Asian children living in USA.Method: BHI is derived from the cortical thickness in the three middle metacarpals. It is determined with the BoneXpert medical device, which automatically analyses a standard bo...

The skeletal effects and new biological effect of Vitamin D are receiving increased attention. However detection methods in 25-hydroxyvitamin D (25(OH) D) measurement are not standardized and variation between laboratories ahd methods has become attractive. This study emphasizes relativity and consistency between ELISA, ESI-LC-MS/MS and electrochemical luminescence analysis which are used widely in China. This study collected 64 cases of blood, and finally obtained good relati...

Purpose: To study the value of the central vertebral height restoration by kyphoplasty for treatment of biconcave vertebral compression fractures.Method: Review the patients with the single biconcave vertebral compression fracture receiving kyphoplasty treatment from 2006 to 2013 (49 cases, 13 males and 36 females) According to Genant classification, with the central vertebral compression ratio, they are divided into type II (<25%, 11 cases), type II...

Background: Surgical and conservative treatments are both crucial method to deal with osteoporotic fracture, anti-osteoporotic therapy is the most important among conservative treatments and diphosphonate medicine is the first-line choice. The pharmacological action of diphosphonate medicine is to inhibit the function of osteoclast, so there is no consensus if it will inhibit porosis and union of fracture.Purpose: To find out the influence of diphosphona...

Background: WHO recommends diagnostic criteria of osteoporosis can be based on double energy absorption of x-ray bone densitometry (DXA), but the DXA method has some limitations such as relatively higher cost, relatively longer detection time, inconvenience in equipment transportation and so on. Quantitative Ultrasound (QUS) method has the potential to diagnose osteoporosis and it is convenient to carry around and low-cost. Asian osteoporosis self-assessment tool (OSTA) is an ...

Background: Vitamin D status is associated with bone health. Vitamin D deficiency leads to decreased bone formation and increased bone resorption. 25-hydroxyvitamin D (25(OH) D), parathyroid hormone (PTH) levels in children could affect bone turnover, and in turn, the bone markers should reflect vitamin D condition. In children the relationships among 25(OH) D, PTH and bone turnover markers are remain.Objective: To explore the associations among serum 25...

Pseudohypoaldosteronism type II (PHAII) is a hereditary disease characterized by hypertension, hypercalciuria and osteopenia. PHAII is caused by mutations in with-no-lysine kinase 1 (WNK1), WNK4, or the cullin RING ligase family members kelch-like 3 (KLHL3) or cullin 3 (CUL3). All mutations result in up-regulation of the WNK signalling pathway which activates thiazide-sensitive Na-Cl cotransporters (NCC) in renal distal tubules, leading to salt retention and hypertension in PH...

Purpose: Osteoporosis (OP) aggravates with vasculature degeneration and improvement of vasculature could prevent OP. We, thus, hypothesize that vascular structure and function play an important role in the development of OP. Type 2 diabetes mellitus (T2DM) patients are vulnerable to vasculopathy, so T2DM were involved in this project to study the correlation between vasculopathy and bone mineral density (BMD).Methods: A total of 427 (180 in OP group; 247...
