This study aimed to estimate the prevalence of and identify the factors influencing female sexual dysfunction (FSD) among Chinese nurses. A cross-sectional survey was conducted from March 2013 to May 2014 among 6 hospitals in Suzhou, China. In total, 2,030 married female nurses were included in the analysis. Data on the sociodemographic, lifestyle, and self-reported health status of the participants were collected, and the participants were asked to complete the Chinese version of the 19-item Female Sexual Function Index (FSFI) questionnaire. In total, 1,035 (50.99%) participants were found to have FSD. Logistic regression analysis showed that increasing age and higher body mass index, lower salary, and poor/very poor self-reported health status were risk factors for FSD; however, regular social activity and physical exercise were protective factors for FSD. The findings of this study suggest that further interventional studies are warranted to study the sexual health among Chinese nurses in detail.

Objective To study the self-adaptive anti-control of a single H-R neuronal system transformed from periodic dynamics pattern to chaos. Methods Numerical analysis was performed by adding sine function self-delay feedback while coupling intensity and time-delay, respectively, as the control parameters. Results By numerical simulation and analysis, it was found that in a certain range of the combination of coupling intensity and time-delay, the time-interval sequences of the dynamical pattern of a single H-R neuronal system could be controlled from a periodical pattern of 3 spikes onto chaos and other periodical patterns. Conclusions The method of self-adaptive feedback of sine function is effective for the anti-control of H-R neuron, and the coupling intensity and time-delay are both important parameters. The particular self-adaptive dynamics of information identification to neuron is reflected in the control process.

Objective To explore the relationship between the concentration of serum magnesium and the short-term outcome of patients with acute ischemic stroke,in order to provide evidence for improving the outcomes.Methods Patients with acute ischemic stroke under study,were from four hospitals in Shandong province.Data on demographic characteristics,life style related risk factors,history of cardiovascular disease,blood pressure at admission and other clinical characteristics were collected for all the participants.The outcomes were defined as National Institutes of Health Stroke Scale (NIHSS) ≥ 10 or death.According to NIHSS,the subjects were divided into two groups:death/NIHSS≥ 10 and NIHSS< 10.Concentrations of Mg2+ were categorized into four levels according to the quartiles of serum magnesium.Cox proportion hazard regression analysis was used to evaluate the association between serum magnesium concentrations and the short-term outcome of acute ischemic stroke.Results In the death/NIHSS≥10 group,concentrations of serum magnesium and the time from onset to admission were lower than that in the NIHSS< 10 group while the systolic blood pressure on admission,the proportion of low density lipoprotein abnormal,impaired fasting glucose and history of auricular fibrillation were all higher than that in the NIHSS< 10 group.Without the adjustment of multiple factors,when comparing to the lowest quartile of serum magnesium level,the fourth quartile (highest) seemed to have had a tendency of reducing the risk of death/NIHSS ≥ 10 (RR=0.47,P< 0.05).When multiple factors were adjusted (adjust serum calcium,potassium level and other factors),the fourth and the third quartiles could both reduce the risk of death/ NIHSS≥10 (RR values were 0.39 and 0.54,P<0.05,respectively).With or without the adjustment of multiple factors,there appeared a dose-response relationship between serum magnesium concentrations and the risk to death/ NIHSS≥10 (trend P<0.05).Conclusion Higher serum magnesium concentrations could reduce the risk to death/NIHSS ≥ 10,suggesting that there was a dose-response relationship between magnesium and the risk to death/NIHSS ≥ 10.

<p><b>OBJECTIVE</b>To evaluate whether the clustering of risk factors, both environmental and genetic, increases the risk of essential hypertension (EH) and the accumulation of risk factors influences the blood pressure level in normotensives.</p><p><b>METHODS</b>On the basis of a prevalence survey, 501 subjects of Mongolian ethnicity (243 hypertensives and 258 normotensives) who were not related to each other were selected to conduct a case-control study. All subjects were interviewed with questionnaires and their blood specimens were collected. Renin gene insertion/deletion (I/D) polymorphism, a new genetic marker, was genotyped with PCR and polyacrylamide gel electrophoresis.</p><p><b>RESULTS</b>Overweight, alcohol consumption, and renin gene I/D polymorphism were significant risk factors of EH (P<0.05). The odds ratios (OR) for the number of risk factors were 2.39 (95%CI: 0.98-6.74) for one risk factor, 5.03 (95%CI: 2.06-14.18) for two, and 6.09 (95%CI: 1.85-22.38) for three respectively after adjusting for age and sex. In normotensives, age- and sex-adjusted mean blood pressures increased with more accumulation of risk factors. However, there were no significant differences among the different blood pressure levels according to the number of risk factors (P>0.05).</p><p><b>CONCLUSION</b>Overweight, alcohol consumption, and renin gene I/D polymorphism are risk factors of EH in the Mongolian ethnic population of China. The accumulation of the risk factors causes a sharp increase of the risk of EH.</p>
