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 purpose of this study is to understand the changes of TBS scores in Asian females by comparing 1990’s and 2010’s DXA images.We have compared the DXA images of 3774 Korean females (age: 20–79) to Japanese (age: 20–79). While Korean DXA images were obtained in 2014 and 2015, Japanese data were obtained in 1996. Participants who have abnormal DXA images or lumbar disease were excluded. TBSiNsight® software (v. 2.1.1, ...

The purpose of this study is to assess the correlation of trabecular bone score (TBS) to variable factors, i.e. sex, age, body size and BMD. Moreover, we want to find variables of correlation coefficient change with aging.We randomly selected 2,906 subjects (1726 female and 1180 male, age range 20’s to 70’s) from several hospitals in Korea. Participants who have abnormal Dual Energy X-ray Absorptiometry (DXA) images or lumbar disease were exclu...

Calcium and vitamin D are essential components for bone health, thus calcium and vitamin D supplementation is an important strategy in the management of osteoporosis.However, the benefit of calcium and vitamin D supplementation on bone health is still controversial. Moreover, potentially harmful effects of excessive calcium supplementation on cardiovascular health are recently suggested. Too high a level of vitamin D has been also reported to have severa...

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...

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...

Purpose: Risk factors for intertrochanteric fracture (IF) severity were not studied thoroughly despite the high failure rate of osteosynthesis. The purpose of this study was to identify the risk factor for each fracture type using AO/OTA classification in elderly female patients who experienced IF.Materials and methods: This retrospective study identified 240 women over 50 years old with an incident IF in whom dual-energy x-ray absorptiometry (DEXA) was ...

Osteoporosis takes the form of porous bone loss which is due to aging, insufficient exercise and unbalanced nutrition and so on. A number of treatments were developed to treat the osteoporosis, which were categorized by pharmacological and non-pharmacological methods. However, it is generally accepted that taking too much pharmacological medication may be harmful to the health. Thus, non-pharmacological treatments are considered as the alternative ways to overcome the side eff...

The receptor activator of NF-kB (RANK) and ITAM-containing adaptors have been identified as essential factors involved in osteoclast formation and bone remodeling, but their mechanisms and interacting factors have not yet been fully identified. Here we report that early estrogen-induced gene 1 (EEIG1), a novel RANK ligand (RANKL)-inducible protein, physically interacts with RANK and further associates with Gab2, PLCg2, and Tec/Btk kinases by RANKL stimulation. Overexpression o...

Chronic tophaceous gout is the natural evolution of untreated gouty arthritis and is characterized by the deposition of solid monosodium urate crystal aggregated in a variety of tissue including joints, bursae and tendons. Tophaceous gout is well-known to cause bone erosions and is characterized by enhanced osteoclasts development. Peripheral blood mononuclear cells (PBMCs) from patients with severe erosive gout showed the preferential ability to transform into osteoclast-like...
