PURPOSE: In this study, we examined the incidence of osteoporosis and the related factors in distal radius fractures (DRFs) caused by minor trauma, as well as the necessity of a bone mineral density (BMD) measurement. MATERIALS AND METHODS: One hundred and sixty patients, who had their BMD measured after DRFs caused by minor trauma, were enrolled in this study. The BMD was measured at the lumbar spine and proximal femur by dual energy X-ray absorptiometry. The BMD values were categorized as normal, osteopenia and osteoporosis by the WHO T-score criteria and each incidence was investigated. The BMD values were compared with the change of age and among age-based groups. The relationship between the BMD and factors such as age, gender, body mass index, or AO classifi cation were assessed. The agreement in BMD values between the lumbar spine and proximal femur was evaluated. RESULTS: The incidence of osteoporosis in DFRs by minor trauma was 74%. The minimum BMD in the DRFs had a negative correlation with age. Signifi cant differences in the BMD values were observed between the groups divided by the 10-year-old intervals (p<0.001) but the differences in the groups aged over 60 were signifi cantly lower than those under the age of 60 (p<0.001). There was a close relationship between the BMD values and the patients' age (p<0.001), but not between the BMD values and the AO classifi cation (p=0.670). The simple agreement between the lumbar spine and proximal femur was 0.619, but the Kappa index was 0.305. CONCLUSION: Because the incidence of osteoporosis in the DRFs by minor trauma is relatively high, it is necessary to measure the BMD. The BMD should be measured at more than two body parts to ensure that osteoporosis accompanied by DRFs is not missed.

PURPOSE: Metastatic cancers spread from the primary site of origin to other parts of the body. Matrix metalloproteinase-9 (MMP-9) is essential in metastatic cancers owing to its major role in cancer cell invasion. Crotonis fructus (CF), the mature fruits of Croton tiglium L., have been used for the treatment of gastrointestinal disturbance in Asia. In this study, the effect of the ethanol extract of CF (CFE) on MMP-9 activity and the invasion of 12-O-tetradecanoylphorbol-13-acetate (TPA)-treated MCF-7 cells was examined. METHODS: The cell viability was evaluated using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay. The expression of MMP-9 was examined by Western blotting, zymography, and real-time polymerase chain reaction. An electrophoretic mobility gel shift assay was performed to detect activator protein-1 (AP-1) DNA binding activity and cell invasiveness was measured by an in vitro Matrigel invasion assay. RESULTS: CFE significantly suppressed MMP-9 expression and activation in a dose-dependent manner. Furthermore, CFE attenuated the TPA-induced activation of AP-1. CONCLUSION: The results indicated that the inhibitory effects of CFE against TPA-induced MMP-9 expression and MCF-7 cell invasion were dependent on the protein kinase C δ/p38/c-Jun N-terminal kinase/AP-1 pathway. Therefore, CFE could restrict breast cancer invasiveness owing to its ability to inhibit MMP-9 activity.
