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 observe the relationship among blood pressure, left ventricular hypertrophy (LVH) and sinus heart rate turbulence (HRT) in patients with essential hypertension (EH) and its clinical significance. Methods: A total of 125 EH patients received 24h ambulatory blood pressure monitoring, dynamic electrocardiogram and echocardiography examination in order to measure 24h mean blood pressure, turbulence onset (TO), turbulence slope (TS) and left ventricular mass index (LVMI). According to 24h mean blood pressure, patients were divided into hypertension stage 1 group (n=46), stage 2 group (n=41) and stage 3 group (n=38); according to LVMI, patients were divided into non- LVH group (n=74) and LVH group (n=51). TO and TS were compared among all groups. Results: TO: Compared with hypertension stage 1 and stage 2 group, there was significant increase in TO [(-2.48±1.75) % vs. (-1.86±1.19) % vs. (-0.87±1.14) %] in hypertension stage 3 group, and that of stage 2 group was significantly higher than that of stage 1 group(P<0.05~<0.01); compared with non- LVH group, there was significant increase in TO [(-0.15±0.45) % vs. (1.08±1.19) %] in LVH group, P<0.01. TS: compared with hypertension stage 1 and stage 2 group, there was significant decrease in TS [(3.76±1.87) ms/RR interval vs. (2.33±1.48) ms/RR interval vs. (1.55±1.06) ms/RR interval] in hypertension stage 3 group, and that of stage 2 group was significantly lower than that of stage 1 group (P<0.05~<0.01); compared with non- LVH group, there was significant decrease in TS [(4.76±1.75) ms/RR interval vs. (3.02±1.08) ms/RR interval] in LVH group, P<0.01. Conclusion: The higher the blood pressure is, the more abnormality the heart rate turbulence is; the heart rate turbulence abnormality of patients complicated with LVH is more severe than that of non- LVH patients in patients with essential hypertension, so heart rate turbulence is help to judge prognosis and guide treatment.

Objective: To investigate the blood lead level (BLL) in painters and the inlfuential factors, and to provide the theory foundation for the prevention and control of lead poisoning in painters. Methods: A total of 535 painters from Sany Heavy Industry Company Limited and Xiangjiang Kansai Paint Corporation, who participated in the health examination during October 2012 and December 2012, were recruited and divided into a positive blood lead group and a negative blood lead group according to the level of blood lead. Questionnaires survey and physical/biochemical examinations were performed. Chi-square Test and multivariate logistic regression were used to estimate the factors that contributed to the elevated blood lead. Results: hTe results from 525 questionnaires and physical/ biochemical examination were collected. There were 55 workers (10.4%) whose BLL were 0.04 mg/L. The maximum value of BLLs was 0.35mg/L. hTe multivariate logistic regression showed that smoking (OR=2.424), smoking or eating in the workplace (OR=2.139), not washing hands before smoking or eating (OR=1.624), and the cycle of changing masks longer than two weeks (OR=2.158) were positively associated with BLL. Conclusion: Smoking, smoking or eating in the workplace, not washing hands before smoking or eating, and the cycle of changing masks longer than two weeks are risk factors for higher BLL.

Objective To investigate the effect of tannic acid on glomerular mesangial cells (GMC),and to clarify the mechanism of tannic acid in improving the pathological changes of diabetic nephropathy (DN)from the aspect of oxidative stress and micro-inflammation. Methods The glomerular mesangial cells were treated with glucose (30 mmol·L-1 )or advanced glycosylation end-products (AGEs)bovine serum albumin(BSA)(250 mg·L-1 )and then different concentrations of tannic acid (10,20,40 and 80μmol·L-1 )were added into the GMC.The cells cultured by normal glucose or treated with BSA were used as control groups and then the level of malonic dialdehyde (MDA), glutathione peroxidase (GSH-Px ), superoxide Dismutase (SOD ), CAT (Catalase ) activities and 8-hydroxy-2′-deoxyguanosine(8-OHdG)levels in the culture supernatant 48 h after culture were determined by colorimetry and ELISA method. The expressions of intercellular cell adhesion molecule-1 (ICAM-1 ) protein, monocyte chemotactic protein 1 (MCP-1 ) and ICAM-1 mRNA in GMC were detected by immunohistochemical staining and RT-PCR method.Results Compared with high glucose and AGEs groups,the MDA levels in tannic acid groups were reduced significantly(P<0.05);the activities of GSH-Px,SOD and CAT were increased significantly(P<0.05 or P<0.01);the 8-OHdG levels in annic acid groups were significantly reduced (P<0.05). Compared with high glucose and AGEs groups,the expressions levels of ICAM-1 protein in 40 and 80μmol· L-1 tannic acid groups were decreased (P<0.05 ). The mRNA expressions levels of MCP-1 and ICAM-1 were significantly lower than those in high glucose group (P<0.01 ).Conclusion Tannic acid could protect GMC against the damage of oxidative and inflammatory mediators,thereby delaying and improving the glomerular lesions of DN.
