BACKGROUND This study aimed to validate the effectiveness of the Osteoporosis Self-assessment Tool for Asians (OSTA) in identifying postmenopausal women at increased risk of primary osteoporosis and painful new osteoporotic vertebral fractures in a large selected Han Chinese population in Beijing. METHODS We assessed the performance of the OSTA in 1201(More)
Both pro-inflammatory cytokines and anti-inflammatory cytokines generated by chondrocytes play essential roles in the process of Rheumatoid arthritis and osteoarthritis (OA). Bornyl acetate is the main volatile constituent in numerous conifer oils and some Chinese traditional herbs, which has displayed an anti-inflammatory effect before. In this study, we(More)
This 12-month retrospective study compared pain relief, quality of life (QoL), treatment cost-effectiveness and complication rates in patients with acute osteoporotic vertebral compression fracture (OVCF) undergoing percutaneous vertebroplasty (PVP; n = 58), percutaneous kyphoplasty (PKP; n = 55), or conservative medical therapy (CMT; n = 55). After(More)
Nanoscale TiN/Ag multilayered films of thickness 500 nm were synthesized on AISI317 stainless steel by ion beam assisted deposition (IBAD) with the modulation period of 4, 5, 6, 7.5, and 12 nm. The bactericidal and biocompatible properties of TiN/Ag multilayered films were investigated through Gram negative E. coli bacteria and L929 cells (mice fibroblast)(More)
The purpose of this study is to identify risk factors related to the development of subsequent fractures after vertebroplasty. A retrospective study was conducted to review 175 patients with a 1-year follow-up who underwent vertebroplasty for first-time and single-level osteoporotic vertebral fractures. Subsequent fractures were diagnosed as recurrent(More)
This study was designed to compare the bone mineral density (BMD) and the prevalence of osteoporosis in community-dwelling women (aged 50-89) living in Northern (Beijing) and Southern (Hong Kong) China. Six thousand ninety-nine ambulatory Chinese women living in Hong Kong and 6302 mainland Chinese women living in Beijing were recruited for the study. The(More)
OBJECTIVE To measure hip bone mineral density (BMD) on different femoral rotations and to identify the influence of femoral rotation during hip densitometry. METHODS Forty women were recruited at the out-department of orthopedic, with the average age of 60.7 years (45-85 years), the average height of 161.8 cm (150-175 cm), and the average weight of 67.4(More)
Amyloid beta (Aβ) is the main component of the amyloid plaques that accumulate in the brains of Alzheimer patients. Here, we reported the protective role of Formononetin (Form) against Aβ25-35-induced neurotoxicity in HT22 cells. We found that Form significantly increased the viability of HT22 cells but decreased the cell apoptosis when challenging with(More)
A sandwich vertebra is formed after multiple osteoporotic vertebral fractures treated by percutaneous vertebroplasty, which has a risk of developing new fractures. The purpose of our study was to (i) investigate the occurrence of new fractures in sandwich vertebra after cement augmentation procedures and to (ii) evaluate the clinical outcomes after(More)
OBJECTIVE To explore the biomechanical effects on adjacent vertebra of thoracolumbar osteoporotic vertebral compression fracture (OVCF) after percutaneous kyphoplasty (PKP) with cement leakage into the disc by using finite element analysis. METHODS T10-L2 segment data were obtained from computed tomography (CT) scans of an elder female with single T12(More)
