ABSTRACT

Objective To investigate the correlation between transformational leadership style and nurses' job satisfaction in emergency department.Method The survey was done among 168 emergency department nurses from 4 first class hospitals in Guangzhou by the demographic information,multifactor leadership questionnaire and Chinese nurses' job satisfaction scale to investigate the status of transformational leadership style perceived by nurses and nurses' job satisfaction in the emergency departments.Results The score of transformational leadership style perceived by the nurses in the emergency department was (50.60±14.40) and jop satisfaction was (79.80±13.30).The transformational leadership style was positively correlated with nurses' job satisfaction (P<0.01).Conclusions The transformational leadership style is middle-high level.The nurses' job satisfaction is at low level,Nursing managers should play an active role in transformational leadership style to enhance nurses' job satisfaction in emergency departments.

ABSTRACT

Objective To investigate the main risk factors influencing the pre-hospital delay of patients with acute ischemic stroke (AIS) for preventing methods.Methods A retrieval was done across the epidemiologic studies on pre-hospital delay of AIS patients during 2004 to 2015 using the key words of ischemic stroke,prehospital delay,treatment delay.According to the inclusion and exclusion criteria,the literature was collected and the literature quality was assessed.The data were extracted for meta-analysis by RevMan software.Results Sixteen epidemiologic studies were included.Totally,there were 2,966 cases of prehospital delay and 2,468 cases of non-delay.The pooled OR values and 95% CI by multivariate analysis were as follows:the degree of awareness of stroke was 0.5 (0.3,0.82),emergency medical service (EMS) was 0.49 (0.29,0.85),National Institute of Health Stroke scale (NHISS) score 0.58 (0.36,0.95),outpatient visit as first visit 4.28 (1.44,12.74),distance 0.76 (0.61,0.95),medical history of ischemic stroke 0.37 (0.18,0.79) (with significant differences in OR value,P<0.05).Conclusions The protective factors for pre-hospital delay of acute ischemic stroke patients include:strengthened awareness of stroke,effective EMS,high NHISS score,short distance,medical history of ischemic stroke.The main risk factor is that their outpatient visit is their first visit for medical treatment.Therefore,we need to enhance the health education to the patients and their families about awareness of stroke,improve the use of EMS and build complete and efficient green path for the stroke patient.

ABSTRACT

Objective To explore the relationships among nurses’intent to stay,occupational commitment and managers’ leadership styles in emergency department.Methods A total of 130 nurses in emergency department were recruited by convenience sampling method from three tertiary hospitals in Guangzhou.They were investigated by using Nurses’Intent to Stay Questionnaire, Nurses’Occupational Commitment Questionnaire and Multifactor Leadership Questionnaire(MLQ).Results The score of nurses’ intent to stay and occupational commitment were(20?19±3?74)and(76?16±12?13),respectively;both were at medium levels and occupational commitment,transformational leadership style were positively correlated with nurses’intent to stay(P<0?05).Nurses perceived their managers as transformational leaders more often than transactional leaders.Conclusions Both the current nurses’ intent to stay,occupational commitment were at medium levels.The influential factors of nurses’intent to stay in emergency department included emergency work experience,emotional commitment and normative commitment.In order to increase nurses’retention and stabilize the healthy development of nursing personnel,nurse managers should improve the level of nurses’occupational commitment.

ABSTRACT

Objective To investigate the effects of angiotensin-(1-7) on angiotensin Ⅱ and its receptor in pressure-overloaded rats. Methods Rat models of pressure-overloaded heart was induced by constriction of abdominal aorta. Forty-five male Sprague Dawley rats were randomized into sham-operated group,model control group and angiotensin-(1-7) treatment group. They were treated with intravenous infusion of 25?g/kg/h angiotensin-(1-7) or same volume of saline after operation. After the treatment for 4 weeks, the ratio of left ventricular weight to body weight(LVW/BW)was determined, angiotensin Ⅱ concentrations in plasma and myocardium were measured by radioimmunoassay, and the expression levels of type 1(AT_1) and type 2(AT_2) angiotension Ⅱ receptor mRNA in left ventricular myocardium were assessed by RT-PCR. Results Compared with sham-operated group, myocardial angiotensin II concentration and AT_1 receptor mRNA level in model control group obviously increased 4 weeks after operation. Compared with model control group, angiotensin II concentrations in plasma and myocardium in angiotensin-(1-7) treatment group had not obvious change, the expression level of myocardial AT_1 receptor mRNA decreased, and the ratio of LVW/BW obviously decreased. There was no significant difference in myocardial AT_2 receptor mRNA level among the three groups. Conclusion Exogenous angiotensin-(1-7) can attenuate cardiac hypertrophy possibly by inhibiting myocardial AT_1 receptor mRNA expression in pressure-overloaded rats.

ABSTRACT

Objective To investigate the diagnostic value of postexercise systolic blood pressure(SBP) response in detecting coronary artery disease(CAD) in patients with electrocardiographic left ventricular(LV) hypertrophy.Methods Acording to their results of selective coronary angiography,58 patients with electrocardiographic LV hypertrophy were divided into group 1(27 patients without significant coronary lesions) and group 2(31 patients with significant coronary lesions).Symptom-limited treadmill exercise testing was conducted in those patients.Results The SBP ratio(SBP at 3 minutes of recovery divided by SBP at peak exercise) was significantly higher in group 2 than in group 1(0 98?0 11 vs 0 84?0 11,P

ABSTRACT

AIM: To investigate the effects and mechanisms of angiotensin-(1-7) on cardiac hypertrophy in pressure-overloaded rats. METHODS: Ar at model of pressure-overloaded heart was induced by constriction of abdominal aorta. Seventy-five male Sprague Dawley rats were randomized to sham-operated group, model control group and angiotensin-(1-7) treatment group. They were treated with intravenous infusion of angiotensin-(1-7) (25 microgram/kg per hour) or saline by minipump. RESULTS: Abdominal aortic banding resulted in a significant increases in LVW/BW, myocardial angiotensinⅡlevels, and p-ERK1/2 expression. Angiotensin-(1-7) had no effect on aortic banding-induced increases in myocardial angiotensinⅡlevels, but it significantly attenuated aortic banding-induced increases in LVW/BW and p-ERK1/2 expression. CONCLUSION: Angiotensin-(1-7) attenuates the development of cardiac hypertrophy in pressure-overloaded rats. It may be associated with the inhibition of p-ERK1/2 expression in cardiac tissue.
