BACKGROUND: Mental health problem is directly correlated with the health and happiness of the elders, and to improve their health level has become a social problem. OBJECTIVE: To investigate the mental health and social support status of the elders in Lishui city. DESIGN: A sample investigation. SETTING: Lishui Center for Disease Prevention and Control.PARTICIPANTS: Totally 137 retirees or honored retirees above 55 years in a community in Liandu district and 136 people above 55 years in a village in Bihu township of Liandu district were taken as the urban and a rural samples respectively in September and October 2003. METHODS: The symptom checklist-90 (SCL-90) and social support rating scale (SSRS) were used. The questionnaires were dispatched, measured and collected by the local physicans in rural area and community cadres in urban area in household anonymously on the spot. MAIN OUTCOME MEASURES: ① Scores of SCL-90 and SSRS in both groups; ② Correlations between social support factors and mental health factors in the elders between urban and rural communities; ③ Comparison of the most common 10 symptoms in SCL-90 between urban and rural elders; ④ Comparison of SCL-90 scores among different age groups and between males and females.RESULTS: Totally 380 questionnaires were sent out, 273 effective ones were collected back, and the collected rate was 71.84%. ① The differences of factor scores in SCL-90 were all significant or markedly significant (P ＜ 0.05-0.01) except that of depression, and all the factor scores in both urban group and rural group were obviously lower than those of national norm (P ＜ 0.01). The differences of subjective support and utilization of support in social support status between the two groups were of marked significance (P ＜ 0.01), whereas the differences of objective support and total scores were not so obvious (P ＞ 0.05). ② The correlation ananlysis between social support and mental health factors in the rural group showed that the utilization of support had no significant correlation with factors of anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism, whereas the other three dimensions and other 10 factors showed significant or very significant correlation. The correlation ananlysis between social support and mental health factors in the urban group showed that there was no significant correlation of objective support with the symptoms of obsession-compulsion and psychoticism, as well as between the utilization of support and the symptom of obsession-compulsion,whereas other dimensions of support showed significant or very significant correlation with other factors. ③ The most common positive symptom with the highest incidence rate was high forgetfulness (79.4%) in the rural group and muscular ache (69.3%) in the rural group, respectively. ④ The scores of interpersonal sensitivity, anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism were lower in the ≥70 years old group than in the ＜ 70 years old group (P ＜ 0.05-0.01); there were no significnat gender differences (P ＞ 0.05).CONCLUSION: The mental health of the elders in Lishui city is slightly better than that of national norm, and it is better in rural area than in urban area. But the existed mental problems should not be ignored. The mental health status is greatly and directly related with the factor of social support, so the major and important measure to improve the mental health of the elders is to better the environment of social support and take effective psychological interference.

Objective To study the current application and influencing factor of emergency medical service in patients with acute heart failure in our hospital.Methods 254 patients with acute heart failure who visited our hospital from January 2008 to December 2010 were selected.Data were collected by questionnaire and medical records in one week after admission to the hospital.The current application and influencing factors of emergency medical service in patients were analyzed.Results Of all the patients with acute heart failme,only 89(35％)arrived at the hospital by emergency medical service,but the rest 165(65％)relied on self-transport.Multivariate logistic analysis showed that age,sex,education level,unbearable symptoms and attribution of symptoms to cardiac origin were independent predictors of the use of emergency medical service.The effective treatment rate was higher,and the pre-hospital time was shorter in patients who used emergency medical service than those relied on self-transport.Conclusions The use rate of emergency medical service in patients with acute heart failure is low,and age,sex,education level,the characters of symptoms and cognitive factors of patients influence the use of emergency medical service in patients with acute heart failure.

Objective To investigate the application effect of intensified nursing intervention in severe pneumonia complicated with ventilator-associated pneumonia. Methods 78 senile patients admitted to hospital with severe pneumonia complicated with ventilator-associated pneumonia from November 2009 to November 2010 were chosen as the research object.They were randomly divided into the observation group and the control group with 39 cases in each group.The control group was treated with conventional and comprehensive methods of care.The observation group was taken intensified intervention on the basis of the control group.The utility time of ventilator after complication with ventilator-associated pneumonia,hospital stay time,complications and mortality rate for the two groups were compared. Results The utility time of ventilator,hospital stay time,complications and mortality rate for the two groups were compared.The observation group had a clear advantage over the control group,there was significant difference. Conclusions Nursing intervention can be targeted to enhance the improvement of the overall respiratory status in severe pneumonia complicated with ventilator-associated pneumonia.It contributes to inflammation control,and can reduce utility time of ventilator and length of hospital stay,reduce the corresponding incidence of complications and mortality rate,it is worthy of clinical application.
