Objective To explore the influencing factors of high risk osteoporosis (OP) population. Methods Using multi-stage cluster sampling method, 1 district was selected from each of the 6 cities randomly, then 3 communities were selected from each district randomly. Questionnaire investigation and physical examination were applied to community residents aged 40-69 years old. The questionnaire mainly included basic information, OP risk assessment (using the 1 minute test method developed by the International OP Foundation), health status and lifestyle information (recent 12 months). The relationship between high-risk groups and influencing factors was analyzed by unconditional logistic regression. Results Totally 6577 valid questionnaires were collected, 2069 were male (31.46％) and 4508 were female (68.54％). A total of 166 cases (2.52％) were found as self-reported OP patients at the age of 40-69, self-reported rate of male (1.55％) was lower than that of female (2.97％) (χ2=11.719, P<0.01), the rate was higher among people aged 60-69 years than people aged 40-49 (χ2=44.766, P<0.01);3400 cases (52.28％) were found as high-risk individuals,there were more male at higher risk than female (OR=1.845). Among different age groups, the 50-59 and 60-69 years age groups had more high risk people than that of 40-49 years group (with OR=2.171 and OR=2.854 respectively). Comparative analysis was also conducted for the following factors: degree of education [college or above (OR=0.517) compared with primary school or junior middle school], occupation [compared with civil servants, technical management personnel (OR=2.289), business services (OR=2.224), farming/forestry/fishing (OR=2.258) and production/transportation staff (OR=2.552)], self-reported history of chronic disease (OR=1.596), fracture (OR=4.061), body pain (OR=2.286) and foot cramps (OR=1.923), as well as calcium/vitamin D intake (OR=1.357), increased sunlight (OR=1.256), daily walking steps>5000 (OR=1.336) and BMI>24.00 (OR=1.322), they were all related to a increased proportion of high risk population. Conclusion The proportion of OP high-risk groups is higher among people aged 40-69. Gender, age, cultural level, occupation, bad health status and lifestyle changes are closely related to higher OP risk. Community residents OP screening should be continued to further study the risk factors of OP.

Objective To study the foxml gene and its protective effect on the lung tissue of rats with acute lung injury (ALI) induced by lipopolysaccharide (LPS), and to observe the dexamethason' s (DEX) impacts on foxml gene and the prognosis of ALI. Method Seventy-two healthy mice were randomly(random number) divid-ed into three groups: control group (A group, n = 24), model group (B group, n = 24) and DEX treatment group (C group, n = 24). The observing intervals were respectively set in 24 h, 48 h and 72 hours. At each ob-serving interval, the foxml protein in lung tissue of mice was detected by using immunohistochemistry (IHC), and the expression of foxml gene in lung tissue was detected by using RT-PCR, as well as to observe the pathological changes in lung tissue. Results Comparisons were made between paired groups at 24 h,48 h and 72 h intervals in which the expression of foxml mRNA and the level of foxml protein in lung tissue of mice in C group were signifi-cantly higher than those in B group (P < 0.05), and those in B group were significantly higher than those in A group (P < 0.05). The expression of foxml mRNA and the level of foxml protein in lung tissue of mice in B group at 48 h interval were significantly higher than those both at intervals of 72 h and 24 h (P < 0.05), and the those at 72 interval were significantly higher than those at 24 h interval (P < 0.05). Compared with B group, the pathologi-cal changes in lung tissue of mice in C group were lessened. Conclusions In both model group and dexamethasone treatment group, the expression of foxml mRNA and the level of foxml protein in lung tissue of mice are increased significantly. Dexamethasone lessens the injury of both vascular endothelial cells and alveolar epithelial ceils of lung tissue, and it also significantly increases the expression of foxml mRNA and the level of foxml protein.

0.05). (2)The 3 plasmids were transfected into fibroblasts and then treated with 10 -5 mol/L and 10 -6 mol/L dexamethasone for 24 h, relative CAT value were different between dexamethasone and control, higher dexamethasone(1?10 -5 mol/L) and lower dexamethasone(1?10 -6 mol/L) ( P

Objective: To compare the value of right ventricular (RV) free wall longitudinal strain (FWLS) by speckle tracking echocardiography (STE) and conventional parameters in evaluation of RV dysfunction in chronic thromboembolic pulmonary hypertension (CTEPH). Methods: Sixty CTEPH patients were enrolled as group A and 45 pulmonary embolism (PE) patients with normal pulmonary pressure were enrolled as group B in this study. CTEPH patients were divided into 2 subgroups using the World Health Organization (WHO) function classification: patients with WHO Ⅰ-Ⅱ were designated as group A1 and those with WHO Ⅲ-Ⅳ were designated as group A2. Conventional RV functional parameters including tricuspid annular plane systolic excursion (TAPSE), tissue Doppler-derived tricuspid annular systolic velocity (S′), fractional area change (FAC), RV index of myocardial performance (RVIMP), and STE-derived RV FWLS were measured and compared. Clinical right heart failure (RHF) was defined as the presence of symptoms of heart failure and signs of systemic circulation congestion during hospitalization. Results: Compared to group B, group A patients had significant enlarged right heart dimension and impaired RV systolic function parameters (all P<0.001). The TAPSE, S′, FAC, and RV FWLS showed significant differences between CTEPH patients with mild (group A1) and severe symptoms (group A2) (all P<0.01), while RVIMP showed no significant difference (P=0.188). On receiver operating characteristic analysis, FWLS had the largest AUC to identify RHF (AUC=0.864, P<0.001), when the cutoff value was 15.05%, the sensitivity was 85.71%, and the specificity was 64.29%, respectively. On binary logistic regression analysis, only right atria area (OR=1.212, 95%CI=1.004-1.48, P=0.046) and RV FWLS (OR=0.662, 95%CI=0.470-0.933, P=0.018) were identified as independent predictor of RHF. Conclusions Compared with conventional parameters, RV FWLS showed advantages in identifying abnormal RV function in CTEPH patients.

Purpose: The present study determined the effects of saphenous nerve stimulation (SNS) at different stimulation frequencies on bladder reflex and explored a possible action mechanism of tibial nerve stimulation (TNS) on bladder activity in cats. Methods: Two bipolar nerve cuff electrodes were implanted on the saphenous nerve and the contralateral tibial nerve in 13 cats, respectively. Multiple cystometrograms were obtained to determine the effects of single SNS at different frequencies and that of combined SNS and TNS on the micturition reflex by infusing normal saline. Results: SNS at 1 Hz significantly reduced the bladder capacity (BC) to 59.8%±7.7% and 59.3%±5.8% of the control level at the intensity threshold (T) and 2T, respectively (P<0.05), while that at 20 Hz significantly increased the BC to 130.6%±4.2% of the control level at 6T (P<0.05). The TNS and SNS at 20 Hz did not significantly change the BCs at 1T (P>0.05), while combined stimulation at 1T significantly increased the BC to 122.7%±1.9% of the control level and induced an inhibitory effect which was similar to that TNS at 2T. Conclusions The current study revealed that SNS reduced and increased BC depending on different stimulation frequencies. The combined SNS and TNS maximized the clinical efficacy at a low intensity. Also, SNS may be a potential therapeutic mechanism of TNS.
