Objective To explore the effect of task-driven teaching methodology based on the action research on cardiopulmonary resuscitation training. Methods The 80 nurses recruited in 2011 were assigned in the control, receiving routine training while another 80 nurses recruited in 2012 were in the study group, where task-driven teaching methodology was used based on the action research. The two groups were compared in terms of results of theoretical and operational examinations. Result The study group was significantly better than the control group in the scores of theoretical and operational examinations ( P < 0 . 05 ) . Conclusion The task-driven teaching methodology based on the action research not only increases the examination results, but also improves the effect of teaching.

Venous thromboembolism is one of the serious and common complications of gynecological malignant tumors, and it is also the main cause of death of patients besides the tumor itself. Nursing staff plays an important role in the prevention of venous thrombosis. Step-by-step systematic nursing intervention can effectively reduce the occurrence of venous thrombosis. This article reviews the research progress of prevention and nursing of perioperative venous thromboembolism in patients with gynecological malignant tumors, aiming to provide help for the establishment and effective implementation of preventive nursing strategies for venous thromboembolism in patients with gynecological malignant tumors.

Objective:To investigate the predictive value of peritoneal protein clearance (Pcl) for cardiovascular events and cardiovascular mortality in peritoneal dialysis (PD) patients.Methods:Eligible PD patients were prospectively enrolled from January 2014 to April 2015 in the PD Center of Renji Hospital, School of Medicine, Shanghai Jiao Tong University. All patients were followed up until death, withdrawing from PD, transferring to other centers, or the end of study period (October 1, 2018). The patients were divided into high Pcl group and low Pcl group by the median Pcl, and the differences of related indicators between the two groups were compared. A multiple linear regression model was used to analyze the influencing factors of Pcl. The Kaplan-Meier method and Log-rank test were used to compare the cumulative survival rates of patients between the two groups. A multivariate Cox regression model was used to estimate the risk of cardiovascular events and cardiovascular mortality in relation to Pcl in PD patients.Results:A total of 271 patients were enrolled, with 135 males (49.8%), age of (56.92±0.84) years old and a median PD duration of 38.77(19.00, 63.10) months. There were 70 patients (25.8%) comorbiding with diabetes and 81 patients (29.9%) with cardiovascular diseases (CVD). The median Pcl of this cohort was 67.93(52.31, 88.36) ml/d. Compared with the low Pcl group (Pcl<67.93 ml/d), the high Pcl group (Pcl≥67.93 ml/d) had older age, and greater proportion of CVD, body mass index (BMI), pulse pressure, brain natriuretic peptide, mass transfer area coefficient of creatinine (MTACcr), and lower serum albumin (all P<0.05). There was no significant difference in gender, dialysis duration, proportion of diabetes, proportion of angiotensin converting enzyme inhibitor and angiotensin receptor blocker, proportion of continuous ambulatory PD, high sensitivity C reactive protein, fluid removal including 24 h urine volume and 24 h ultrafiltration, and residual renal function between the two groups (all P>0.05). Multiple linear regression analysis showed that serum albumin ( β=-0.388, P<0.001), BMI ( β=0.189, P<0.001), and MTACcr ( β=0.247, P<0.001) were independently related to lg(Pcl). During the study period, 55 patients experienced one or more cardiovascular events and 39 patients had cardiovascular mortality. According to Kaplan-Meier analysis, cardiovascular mortality in the high Pcl group was higher than that of low Pcl group (Log-rank χ2=6.902, P=0.009). Multivariate Cox regression analysis showed that, high lg(Pcl) was an independent influencing factor of cardiovascular events in PD patients ( HR=7.654, 95% CI 1.676-34.945, P=0.009). Conclusions:Serum albumin, BMI and MTACcr are independently associated with Pcl, and Pcl is an independent predictor of cardiovascular events in PD patients.
