ABSTRACT
Objective:To learn about the incidence of hypertension in residents of arsenic exposure areas of Togtoh County, Inner Mongolia Autonomous Region, and to analyze the influencing factors of hypertension.Methods:In Inner Mongolia Autonomous Region, Ciweigou of Togtoh County, a drinking water-type endemic arsenic poisoning area, and Lanjiayao of Horinger County, a non-arsenic poisoning area with similar living habits and economic conditions, permanent residents who had lived for ≥10 years were selected as the survey subjects. Totally 116 residents of Ciweigou (exposure group) and 68 residents of Lanjiayao (control group) were included in the survey. Blood pressure was measured and the contents of arsenic, selenium, lead and chromium in urine were detected, multivariate logistic regression was used to analyze the influencing factors of hypertension.Results:The detection rates of hypertension in exposure group and control group were 53.45% (62/116) and 70.59% (48/68), respectively, and the difference between the two groups was statistically significant (χ 2 = 5.33, P = 0.022). The contents of arsenic, selenium and chromium in urine of exposure group were higher than those of control group, and the content of lead in urine was lower than that of control group, and the differences were statistically significant ( Z = 13.04, 6.34, 11.28, - 9.91, P < 0.001). The results of multivariate logistic regression analysis showed that female, age ≥60 years old and high urinary arsenic content were the influencing factors of hypertension [odds ratio ( OR) = 2.074, 2.004, 0.424, 95% confidence interval ( CI): 1.113 - 3.866, 1.035 - 3.879, 0.219 - 0.820] in arsenic exposure areas. Conclusion:Female, age ≥60 years old and high urinary arsenic content are the influencing factors of hypertension in arsenic exposure areas of Togtoh County, Inner Mongolia Autonomous Region.
ABSTRACT
<p><b>BACKGROUND</b>The new medical insurance policy (JRSYF(2010) No.255) was released by the Beijing Municipal Government and became effective on January 1, 2011. Medical expenses incurred during a stay in an emergency department (ED) observation unit can be reimbursed as a hospital admission. The aim of this study was to evaluate the impact of a new charging scheme during stays in ED observation unit under Beijing's Basic Medical Insurance.</p><p><b>METHODS</b>Data for those patients who had stayed in ED observation unit in 2010 (before the implementation of a new charging scheme) and 2012 (after the implementation of this policy) were retrospectively analyzed in terms of length of stay, patients who were observed (PO), and median medical costs.</p><p><b>RESULTS</b>After the implementation of a new charging scheme, compared with the year of 2010, in year of 2012, there were statistically significant longer lengths of stay at the observation unit (6 (4-9) vs. 5 (4-7) days; P < 0.001), more PO (2 257 vs. 1 783; P < 0.001), and more median medical costs (RMB 6 026 vs. 3 650 Yuan; P < 0.01). The proportion of elderly patients (≥ 60 years of age) in 2012 was larger than that in 2010 (70.22% vs. 63.71%; P < 0.01). It was performed on those patients who were admitted after the implementation of a new charging scheme. Compared with patients who were not admitted had stayed in ED observation units, the patients who were admitted had stayed in ED observation units that had a higher proportion for >15 days (36.22% vs. 5.61%; P < 0.01); they had higher median medical costs RMB (9 186 vs. 5 668 Yuan; P < 0.001) and they were more elderly (≥ 60 years of age) (86.10% vs. 66.39%; P < 0.01).</p><p><b>CONCLUSIONS</b>The new charging scheme under Beijing's Basic Medical Insurance allows patients to get access to inpatient admission more easily. It lowers patients' financial burden in ED observation unit. Since more people stay at ED observation unit, it increases ED payments by the insurance system. However, it slows the turnover rate of ED observation unit and causes overcrowding in ED. Hence, the advantages and disadvantages of the new policy are obvious.</p>

BACKGROUND:With the increasing incidence of distal tibial fractures, locking plate fixation has become the preferred internal fixation method. OBJECTIVE:To analyze the biomechanical performance of distal tibial fractures, and to study the difference between medial and lateral locking plate methods for internal fixation of distal tibial fractures. METHODS:Articles concerning the biomechanics of the internal fixation of distal tibial fractures were col ected by literature search. The articles that met the criteria were analyzed in depth. In this paper, a biomechanical comparison between locking plate fixation and intramedul ary nail fixation was done as wel as the stress distribution and mechanism of the ankle joint. Meanwhile, 60 patients with distal tibial fractures who had received medial or lateral locking plate fixation at the Department of Orthopedics, Chongming Branch, Xin Hua Hospital Affiliated to Shanghai Jiao Tong University School of Medicine, China from January 2009 to January 2012 were enrol ed for efficiency comparison. RESULTS AND CONCLUSION: For patients with distal tibial fractures, it is easy to cause posterior mal eolus fractures, Y-shaped fractures and anterior tibial compression, respectively, in the plantar flexion position, neutral position, and dorsiflexion position. Locking plate is better than the intramedul ary nail in the torsional force, and the intact fibula contributes to the improvement of fixed effects of these two internal fixation methods. When the fibula cannot be effectively fixed, the locking plate fixation has a better stability than the intramedul ary nail. Moreover, there is no difference in the fracture healing after fixation with medial and lateral locking plates. However, a lower incidence of complications and better function recovery of the ankle joint can be realized after lateral locking plate fixation.
ABSTRACT
OBJECTIVE To investigate the significance of the Fas and TNF-? receptor mediated apoptosis and IL-8 associated with the pathogenesis of aged COPD.METHODS We measured the circulating soluble Fas,tumor(necrosis) factor alpha(TNF-?) and interleukin-8 level in peripheral blood of 40 patients with aged chronic(obstructive) pulmonary disease (COPD).In contrast with the aged COPD group,30 healthy old people were(observed) as a control.RESULTS The level of soluble Fas,TNF-? and IL-8 in peripheral blood of these patients was higher than control((P
ABSTRACT
5.5 the separation was not achieved.The compound of cyclodextrin and terbutaline increased with the increase of cyclodextrin when the volume rate of cyclodextrin was 0.4% 1.6%,making terbutaline easier for separation.Conclusion:The types of ? CD,the concentration and pH of buffer are the major factors influencing the separation of terbutaline and it can be completely separated.
