Objectives To investigate the current status of nurses' turnover intention and job satisfaction in secondary and tertiary women and children's hospitals in Guangzhou. Methods 3 026 nurses were enrolled in this study, which were from a tertiary hospital in Guangzhou urban area and another 4 secondary hospitals located in rural districts, namely Huadu, Nansha, Conghua, Zengcheng. Systematic sampling was adopted. The Mueller/McCloskey Nurse Job Satisfaction Scale (MMSS) and Turnover IntentionQuestionaire(TIQ)were applied to carry out this investigation. Differences of nurses' turnover intention and job satisfaction between different levels' hospitals were compared and analyzed. Results Compared with those in the secondary hospitals, nurses in the tertiary maternity hospital were at higher average age, had better academic backgrounds with higher professional titles, more bonus and more positions of establishment. The differences all were statistically significant (P<0.05). The average scores of turnover intention for nurses from the secondary and tertiary hospitals were2.38±0.682 and 2.87 ±0.570 respectively. All the differences were statistically significant (P<0.05). Conclusion Compared with those in the secondary maternal and child health hospitals, nurses in the tertiary hospitals were more willing to leave and had lower job satisfaction. Nurse's managers may take effective measurses to increase nurse's satisfaction.

Objective To compare the clinical efficacy of bronchoalveolar lavage and conventional treatment in patients with severe pulmonary infection. Methods 92 patients with severe pulmonary infection treated in our hospital from May 2015 to April 2017 were selected as research objects. They were randomly divided into experimental group (n=46) and control group (n=46). The control group was treated with conventional symptomatic treatment, The experimental group implemented bronchoscopy lung lavage treatment. After treatment, blood gas bronchoscopic airway lavage in two groups were detected with analysis indexes. Serum inflammatory factors were determined by ELISA, and the serum levels of stress hormones were determined by radioimmunoassay. Results After the treatment, the PaO₂, SaO₂ and PaCO₂ in the experimental group were higher than those in the controlgroup(P<0.05). The levels of serum inflammatory factors hs-CRP, IL-6、IL-8 in the experimental group were lower than those in the control group (P<0.05); in addition, the levels of Ang-II, NE and Cor in the experimental group were lower than those in the control group(P<0.05). Conclusion Bronchoscopy airway lavage may help to improve the pulmonary ventilation function of patients with severe pulmonary infection, reduce the degree of systemic inflammatory stress, and promote disease recovery.
