Objective T o observe the expression changes of hypoxia inducible factor-1α (H IF-1α) and vascular endothelial grow th factor-A (V E G F-A ) in rats w ith arrhythm ias, and to explore the differences of the expression pattern in the tw o indicators of acute m yocardial ischem ia caused by arrhythm ias and coronary insufficiency. Methods T he arrhythm ia w as induced by C aC l2, and the expression changes of H IF-1α and V E G F-A w ere detected by im m unohistochem istry, W estern blotting and real-tim e PC R w ithin 6 h after the arrhythm ia in rats. Results T he expression of H IF-1α and V E G F-A show ed diffuse in the m yocardial tissue of rats died from arrhythm ias. B oth of them increased in the early arrhythm ia, then decreased. E xtensive m yocardial ischem ia happened at the beginning of arrhythm ia occurrence and its range didn't expand w ith tim e. Conclusion T he expressions of H IF-1α and V E G F-A in m yocardium of the rats w ith arrhythm ia can provide evidence for the differential diagnosis of acute m yocardial is-chem ia caused by fatal arrhythm ia and coronary insufficiency.

OBJECTIVE: To evaluate the safety and efficacy of Chaige Qingre Granule, a traditional Chinese compound herbal medicine, in treating acute upper respiratory tract infection of wind heat syndrome. METHODS: A multi-center, double-blinded, randomized controlled trial was conducted. In the phase II, 60 patients with acute upper respiratory tract infection were randomly divided into the trial group (n=30) and the control group (n=30). In the phase III, 112 patients were randomly divided into the trial group (n=84) and the control group (n=28). The trial group received 6 g Chaige Qingre Granule, and the control group received 6 g Fufang Shuanghua Granule (another traditional Chinese compound herbal medicine). The two groups were all treated for 3 days and four times daily. Clinical symptoms, syndromes, adverse effect, blood, urine and stool test, hepatorenal function and electrocardiogram were examined before and after the treatment. RESULTS: After treatment, the overall obvious response rates of the trial group and the control group were 78.57%, 82.14% (by per-protocol analysis) and 75.86%, 79.31% (by intention-to-treat analysis) respectively, and the overall response rates of the two groups were 96.43%, 100% (by per-protocol analysis) and 93.10%, 96.55% (by intention-to-treat analysis) respectively in phase II. There were no significant differences between the two groups (P>0.05). In the phase III, the overall obvious response rates of the trial group and the control group were 90.54%, 73.08% (by per-protocol analysis) and 88.16%, 70.37% (by intention-to-treat analysis) respectively, and the overall response rates of the two groups were 94.59%, 96.15% (by per-protocol analysis) and 92.11%, 92.59% (by intention-to-treat analysis) respectively. There were no statistical differences between the two groups (P>0.05) too. No adverse effects were found in the trial. CONCLUSION: Chaige Qingre Granule is effective and safe in treating acute upper respiratory tract infection of wind heat syndrome.

OBJECTIVE: To evaluate the efficacy and safety of Mahuang Zhisou Capsule (MHZSC), a compound traditional Chinese herbal medicine, in treatment of acute upper respiratory tract infection of wind-cold syndrome. METHODS: A multi-center, double-blind, double dummy, randomized controlled trial was conducted. A total of 240 patients were randomized into treatment group (120 cases, treated with MHZSC) and control group (120 cases, treated with Mahuang Zhisou Pill). The therapeutic course was 3 days. RESULTS: Seven cases were excluded and three cases lost to follow-up. Two hundred and thirty-three cases entered intention-to-treat (ITT) analysis and 230 cases fitted in per-protocol population set (PPS) analysis. After treatment, the therapeutic effect of upper respiratory tract infection was calculated by ITT and PPS analysis respectively. The significant response rate and total response rate in the treatment group were 78.07% and 98.25% (ITT and PPS), while the significant response rates in the control group were 70.59% (ITT) and 70.69%(PPS), and the total response rates were 95.80% (ITT) and 95.69% (PPS) respectively. There were no significant differences in clinical efficacy between the two groups (P>0.05). CONCLUSION: MHZSC is effective and safe in treatment of acute upper respiratory tract infection of external wind-cold syndrome.

OBJECTIVE: To evaluate the safety and efficacy of Yiqi Pingchuan Granule in treating acute attack of asthma due to qi deficiency and cold syndrome. METHODS: A randomized controlled trial was conducted. A total of 80 patients with an acute attack of asthma were included. They were allocated into two groups randomly in a ratio of three to one. Sixty patients in the treatment group received Yiqi Pingchuan Granule and 20 patients in the control group received Ruyi Dingchuan Pill. Patients in both groups were treated for 7 days. RESULTS: There were no significant differences in traditional Chinese medicine syndrome, clinical symptoms and lung function between the two groups (P>0.05). After treatment, the forced expiratory volume in 1 second was increased in the treatment group (P<0.05), and the peak expiratory flow was accelerated in the control group (P<0.05). No significant side effects were noted in both groups. CONCLUSION: Yiqi Pingchuan Granule is safe and effective in treating acute attack of asthma due to qi deficiency and cold syndrome.

Objective: To explore the turnover intention of nurses in Quzhou and its influential factors. Methods: From July to August in 2017 cross-sectional study and self-filled questionnaire are used to investigate 980 nurses from 7 hospitals in Quzhou, including two third-level hospitals and five second-level ones. T-test, F-test, Pearson and linear regression are used in data with the method of statistical analysis. Results: The total score of turnover intention of nurses was (14.95±3.17) points, and the index value was 62.27%, of which the turnover intention was above 78%. The analysis of Single factor showed that age (F=4.895) , Department (F=2.971) , title, nursing age (F=5.863) , self-assessment of physical conditions (F=4.092) were closely related to nurses’ turnover intention(P<0.05). According to Person’s correlation analysis, there are positive correlations between turnover intention and source of stressor, and moral distress (P<0.05) . Multiple linear regression showed that the nurses’ turnover intention was age, Department, health selfevaluation, stressor and moral distress. Conclusion The turnover intention of nurses is high, which is related to age, Department, self-evaluation of health, stressor and moral distress.
