Objective To study the clinical methods and effects of root cause analysis on the application of the Swiss cheese model in the psychiatric nursing adverse events. Methods Safety management groups were established to train nurses, use Swiss cheese model to analysis the root cause,formulate the corrective measures. The annual rates of incidence and reporting rate of adverse events were compared. Results One year after the root cause analysis on the application of the Swiss cheese model,the annual number of patients increased from 3 420 to 3 730,the cases of nursing adverse events reduced from 141 to 120,and the rate of nursing adverse events dropped from 4.12 percents to 3.21 percents (X2=4.16,P<0.05). The reporting cases of nursing adverse events increased from 65 to 102,and the reporting rate of nursing adverse events enhanced from 46.10 percents to 85.00 percents ( X2=42.57,P<0.01). Conclusions The use of root cause analysis on the application of the Swiss cheese model is the effective management model to analyze the nursing adverse events and to improve the nursing safety.

Objective To observe the efficacy of somatostatin on elderly patients with acute suppurative cholecystitis and its impact on the C-reactive protein (CRP), prealbumin (PA) and total bilirubin (TBIL) effects before or after operation. Method 110 elderly patients with acute suppurative cholecystitis, which from January 2011 to June 2013, were randomly divided into observation group and control group, each group had 55 cases, the control group were gave operation, the observation group were treated with somatostatin on basis of control group before and after operation. The operative time, blood loss, postoperative visual analog scale (VAS) score and morbidity were observed. At the same time, the levels of CRP, PA and TBIL were detected before and after operation. Results After treatment, the blood loss, postoperative hospital stay and postoperative complication rate in observation group were significantly lower than those in control group (P<0.01), while the differences in operative time and postoperative VAS score between two groups were not significant . After treatment, the levels of CRP, and TBIL appear significantly lower than those before treatment (P<0.01), while the PA levels appear significantly higher compared with those before treatment (P<0.01), the decreasing or increasing levels in observation group were more obvious compared with control group (P<0.01). Conclusion The adjuvant therapy efficacy of somatostatin were obvious before and after operation, they can significantly reduce the body's inflammatory response, and promote the postoperative recovery.

Objective:To understand the relationship between psychiatric nurses' communication ability, personality characteristics and conflict management patterns, and to provide a basis for training psychiatric nurses' conflict management ability courses.Methods:A convenient sampling method was used to investigate and investigate 208 nurses in the first-line clinical hospitals of a third-class psychiatric hospital, used the nurses′ clinical communication ability scale, the nurse′s interpersonal conflict management morphology scale, and the simplified version of the Chinese Big Five Personality Questionnaire.Results:Integration dimension (18.67±2.58) points, concession dimension (12.93±2.43) points, escape dimension (14.05±2.02) points, dominance dimension (14.49±3.06) points, and integration dimension and gender ( t value was -2.57, P=0.01)), education ( F value was 3.76, P=0.02), technical title ( F value was 3.03, P=0.02), position ( t value was 2.08, P=0.03), whether to participate in nurse-patient communication training ( t value was 2.54, P=0.02). Nurses with pleasant personality could better deal with interpersonal conflict ( r=0.361, P<0.01), and the nurse′s personality had a direct effect on the form of interpersonal conflict ( P=0.036, 95% CI 0.107-0.422), the nurse′s communication ability plays a part of indirect effect ( P=0.031, 95% CI 0.001-0.063). Conclusion:The form of interpersonal conflict management of psychiatric nurses was closely related to communication ability and personality characteristics. Nursing managers could carry out targeted training to improve the conflict management ability of nursing staff.

AIM　To study the effects of Phe-Met-Arg-Phe-NH2 (FMRFa) on Na+/Ca2+ exchange and its specificity for Na+/Ca2+ exchange in rat ventricular myocytes. METHODS　Na+/Ca2+ exchange current and other currents of ion channels were measured using whole cell voltage clamp techniques. RESULTS　A dose-related inhibition of tetrapeptide FMRFa on Na+/Ca2+ exchange was observed in rat ventricular myocytes. Inward and outward INa+/Ca2+ were inhibited by 60.1% and 56.5%, respectively, at highest concentration (100 μmol*L-1) and its IC50 were 20 μmol*L-1 and 34 μmol*L-1 in inward and outward INa+/Ca2+, respectively. Inward and outward INa+/Ca2+ were inhibited 38.7% and 34.9%, respectively, at FMRFa 5 μmol*L-1. FMRFa 5 μmol*L-1 and 20 μmol*L-1 did not affect L-type calcium current, sodium current, transient outward current and inward rectifier potassium current. CONCLUSION　These data indicate that FMRFa is a specific inhibitor of Na+/Ca2+ exchange in intact rat ventricular myocytes.
