Background: Experimental studies have suggested that soybean products may protect against ischemic stroke, but only limited epidemiological evidence is available. Objective: Our aim was to investigate the relationship between soy food consumption and the risk of ischemic stroke among the Chinese population. Methods: A case-control study was conducted in southern China during 2007–2008. Soy food consumption, dietary intake and lifestyle information were obtained from 374 incident ischemic stroke patients and 464 hospital-based controls. Logistic regression analyses were performed to assess the association between soy food intake and the ischemic stroke risk. Results: The mean weekly soy food intake was significantly lower (p = 0.001) among cases (89.9, SD = 239.3 g) than control subjects (267.7, SD = 426.1 g). Increased consumptions of dried soybean, tofu, soymilk and total soy foods were associated with reduced risks of ischemic stroke after adjusting for confounding factors. The corresponding adjusted odds ratios for the highest versus lowest level (<50 g) of intake were 0.20 (95% confidence interval = 0.09–0.48), 0.56 (0.36–0.89), 0.18 (0.06–0.51) and 0.23 (0.14–0.39), with significant dose-response relationships observed. Conclusion: The results provided evidence of inverse association between habitual soy food consumption and the risk of ischemic stroke for Chinese adults.
The objective of this study was to reveal the relationships of mental health, social support, health-related quality of life (HRQOL) as well as their dimensions in HIV-positive men who have sex with men (MSM).HIV-positive MSM were interviewed by a cross-sectional study design using the world Health Organization quality of life bref scale, social support rating scale, and self-rated anxiety and depression scales. Canonical correlation analysis and structural equation model (SEM) were utilized to analyze to the collected data.Three first pair of canonical variables that was statistically significant (P < .0001) and verified could account for the largest cumulative proportion were computed from canonical correlation analysis. The results showed, among the dimensions, depression and anxiety were negatively correlated with support utilization and physical health, while subjective support and support utilization were positively correlation with social relationship health. Structural equation model results showed that support utilization (0.632, T = 10.44), depression (0.816, T = 20.37), and environmental dimension (0.833, T = 38.47) had the largest standardized factor loading in social support, mental health, and HRQOL. The structural coefficient between social support and mental health was −0.433 (T = −5.88), between mental health and HRQOL was −0.592 (T = −10.33), between social support and HRQOL was 0.290 (T = 4.10), indicated social support not only exerted a direct influence, but also mediated mental health to have an indirect effect on HRQOL for HIV-positive MSM.Environmental dimension is the foremost factor of HRQOL for HIV-positive MSM. Alleviating anxiety symptoms maybe improve physical health, while promoting the support utilization is an effective measure of alleviating depression and improving social relationship health for this special group.
Dyslipidemia is a well-established risk factor for atherosclerosis. Treating dyslipidemia in elderly patients requires specific knowledge and understanding of common dyslipidemias and the relative safety of various pharmacologic agents in the presence of possible multiple comorbidities. Lifestyle modification remains the first step in the treatment of dyslipidemia; however, it can be difficult to sustain and achieve acceptable compliance in the elderly and it is best used in combination with drug therapy. Statins are widely accepted as the first-line therapy. Several recent studies have demonstrated that statins are safe and effective in the elderly. However, it is important to note that there is very limited data regarding the effects of dyslipidemia treatment on morbidity and mortality in patients over 85 years of age. In summary, the clinicians must recognize that the presence of dyslipidemia in the elderly poses substantial risk of coronary events and stroke. The available evidence has demonstrated that in most elderly patients who are at increased risk for cardiovascular morbidity and mortality, treatment of dyslipidemia with appropriate therapy reduces the risk, and when used carefully with close monitoring for safety, the treatment is generally well tolerated. With increasing life expectancy, it is critical for physicians to recognize the importance of detection and treatment of dyslipidemia in the elderly.
The paper constructed agricultural film pollution EKC model of vegetable industry in Hebei province, Based on 1999-2011 vegetables average yield per hectare as vegetable industry development level ,the density of agricultural films as variable combined with planting area and total production time index. The empirical results has shown that the relationship between the density of agricultural films in Hebei province and economic development is with linear growth characteristic not a typical inverted "U" type EKC characteristic. Therefore, in the process of making vegetables industry policy and vegetables environmental protection policy, the government should take measures to control the occurrence of vegetables agricultural films source pollution actively. Not using the inverted U type of EKC curve does as the excuse of first pollution, after management.
