BACKGROUND:The diagnosis of osteoporosis depends upon the bone mineral density T-score of ≤ -2.5 standard deviation or brittle fractures. Bone mineral density measurement combined with vertebral fracture assessment might prevent the missed diagnosis of osteoporosis due to bone mineral density evaluation alone, and improve the diagnosis rate of osteoporosis.
OBJECTIVE:To evaluate the effect of bone mineral density measurements combined with vertebral fracture assessment for the diagnosis of osteoporosis.
METHODS:Bone mineral density measurements of proximal femur and vertebral fracture assessment for lateral thoraco-lumbar images were consecutively done for 217 postmenopausal women who aged ≥ 50 years. The rate of osteoporosis diagnosed with bone mineral density T score was compared with that diagnosed with bone mineral density combined with vertebral fracture assessment. The effects of bone mineral density on the vertebral fracture were analyzed.
RESULTS AND CONCLUSION:92 (42.4%) patients had bone mineral density T score ≤ -2.5, which met the threshold for diagnosis of osteoporosis. 102 (47.0%) patients had osteopanic (-1>T>-2.5) and 23 (10.6%) had normal range of bone mineral density. 158 patients had no vertebral fractures and 59 (27.2%) patients had 101 vertebral fractures. The vertebral fracture rate was 21.6%in the patients with bone mineral density T> -2.5 and 34.8%in the patients with bone mineral density T ≤ -2.5, with significant differences (P<0.05). Bone mineral density in combination with vertebral fracture assessment for the diagnosis rate of osteoporosis was up to 54.8%, which was significantly higher than the rate diagnosed with only bone mineral density (12.4%;P=0.01). Bone mineral density measurement combined with vertebral fracture assessment improves the diagnosis of osteoporosis for postmenopausal women.

Objective To compare the efficacy of sedation with dexmedetomidine versus midazolam in mechanically ventilated patients.Methods Sixty patients aged 20-64 yr,with body mass index 21-25 kg/m2,APECHE Ⅱ score 10-25,requiring 24 h of nechanical ventilation in intensive care unit (ICU),were randomly divided into 2 groups (n=30 each): midazolam group (group M) and dexmedetomidine group (group D).A loading dose of midazolam 0.05 mg/kg was injected intravenously,followed by infusion at 0.03-0.20 mg· kg-1 · h-1 in group M.A loading dose of dexmedetomidine 1 μg/kg was injected intravenously,followed by infusion at 0.2-0.7 μg· kg-1 · h-1 in group D.Ramsay sedation score was maintained at 2-4.The satisfaction of the doctors in ICU with the sedative efficacy,hypotension and bradycardia were recorded.Delirium was recorded starting from the begging of sedation to 2 h after the end of sedation.The emergence time and occurrence of falling asleep again within 2 h after waking were also recorded.Results Compared with M group,the satisfactory level of the doctors in ICU with the sedative efficacy was significantly increased,the emergence time was significantly shortened and the incidences of falling asleep again within 2 h after waking and delirium were significantly decreased (P ＜ 0.05 or 0.01),and no significant change was found in the incidence of hypotension and bradycardia in group D (P ＞ 0.05).Conclusion The efficacy of sedation with dexmedetomidine is better than that of midazolam in mechanically ventilated patients.

BACKGROUND:The prevalence of osteoporosis is high in the patients undergoing total hip arthroplasty. Osteoporosis is associated with the survival of prostheses. Both canal flare index and bone mineral density are aged-related.
OBJECTIVE:To study the cxorrelation between canal flare index of the proximal femur and bone mineral density of femoral neck, and to pay more attention to osteoporosis.
METHODS:A retrospective study of the correlation between canal flare index of the proximal femur on pelvic radiograph and bone mineral density of femoral neck was made in 57 patients undergoing total hip arthroplasty.
RESULTS AND CONCLUSION:The canal flare index were ranged 1.8-4.8 (3.1±0.7) in 57 patients. There were 23 patients in canal flare index<3 (chimney-type medul ary cavity), 33 in canal flare index between 3 and 4.7 (normal-type medul ary cavity), and one in canal flare index>4.7 (funnel-type medul ary cavity). The age had an impact on the type of medul ary cavity. The prevalence of chimney-type medul ary cavity were significantly higher in>60 years old group than≤60 years old group, and bone mineral density of femoral neck in the group of canal flare index≥3 was significantly higher than the group of canal flare index<3. The bone mineral density of femoral neck was gradual y reduced with age, and were significantly higher in≤60 years old group than in>60 years old group [(0.751±0.235) g/cm2, (0.590±0.092) g/cm2, P=0.000]. As bone mineral density reduced, canal flare index was also decreased. Experimental findings indicate that, the bone mineral density of femoral neck is significantly correlated with canal flare index.
