Objective To explore the practice and effect of peer education in improving the empathic ability of in-service nurses. Methods A total of 122 in-service nurses at a tertiary hospital scoring below 60％ in empathy ability, were randomly divided into a control group and a research group by data table method. The nurses in the control group received theoretical training in empathy, and the nurses in the research group participated in peer-educated periodic empathy training activities. The Chinese version of interpersonal response index scale ( IRI-C) , nurses'humanistic care quality table, general self-efficacy scale were used before and after intervention. Results Before the intervention, the scores of the two groups of Chinese version of interpersonal response index scale ( IRI-C) , perspective-taking ( PT) , Fantasies ( FS) , empathic concern (EC) and Personal Distress (PD) were not statistically significant (P >0. 05). After intervention, the scores of the two groups of Chinese version of interpersonal response index scale ( IRI-C) , Fantasies ( FS) and Personal Distress ( PD) scores in the research group were all higher than those in the control group (P<0. 05). There was no significant difference in the scoring before and after intervention in the control group (P>0. 05). The total score and personal pain (PD) dimensions of the Chinese version of interpersonal response index scale ( IRI-C) were significantly higher than those before the intervention ( P<0. 01). The total score of nurses' humanistic care quality, the score of humanistic care ability and humanistic care perception were all higher than those before intervention in the study group (P<0. 05), and differences are statistically significant. Conclusions The practice of peer-education empathy training can effectively improve the empathy and humanistic care quality of the in-service nurses, and improve the nursing service level.

Objective To systematically evaluate the clinical effect of surgery combined with adjuvant therapy (postoperative chemoradiotherapy or chemotherapy) and single surgery for resectable pancreatic cancers.Methods Literatures were researched using PubMed,Embase,Science Citation Index Expanded,Cochrane Central Register of Controlled Trials and China Biology Medicine disc with the key words including "pancreatic cancer,adjuvant therapy,chemoradiotherapy,radiochemotherapy,chemotherapy,radiotherapy,胰腺癌,辅助治疗,化学治疗and放射治疗”from the time of database building to October 2016.Two reviewers independently screened literatures,extracted data and assessed the risk of bias.All the patients undergoing surgery combined with adjuvant chemoradiotherapy,surgery combined with adjuvant chemotherapy and single surgery were respectively allocated into the first treatment group,second treatment group and control group.The inverse variance was used for mergering hazard ratio (HR) and related statistic data.HR and 95％ confidence interval (CI) were used for assessing the overall survival time and disease-free survival time.The median survival time and 1-,2-,5-year survival rates were evaluated by the relative risk (RR) and 95％CI.The heterogeneity of the studies was analyzed using the I2 test.Results Eleven randomized controlled trials (RCTs) of 9 literatures were retrieved,and the total sample size was 1 482 patients,including 238 patients in the first treatment group,545 in the second treatment group and 699 in the control group.Results of Meta analysis:① overall survival time:there was no significant difference in overall survival time between the first treatment group and control group (HR =0.87,95％ CI:0.56-1.17,P＞ 0.05).There was a significant difference in overall survival time between the second treatment group and control group (HR =0.68,95 ％ CI:0.55-0.80,P＜ 0.05).② Disease-free survival time:there was no significant difference in disease-free survival time between the first treatment group and control group (HR=0.78,95％CI:0.53-1.03,P＞0.05).There was a significant difference in disease-free survival time between the second treatment group and control group (HR=0.56,95％CI:0.45-0.67,P＜0.05).③ Median survival time:there were significant differences in median survival time between the first treatment group and control group (RR=1.82,95％CI:1.35-2.45,P＜0.05) between the second group and control group (RR=1.32,95％CI:1.07-1.62,P＜0.05).④ One-,2-,5-year survival rates:there was no significant difference in 1-,2-,5-year survival rates between the first treatment group and control group (RR=1.24,2.47,1.15,95％ CI:0.72-2.12,0.82-7.41,0.71-1.84,P＞0.05).One-year survival rate in the second treatment group was compared with that in the control group,with no significant difference (RR=1.15,95％CI:0.99-1.34,P＞0.05).There were significant differences in 2-and 5-year survival rates between the second treatment group and control group (RR=1.24,1.73,95％CI:1.01-1.50,1.32-2.27,P＜0.05).Conclusions Compared with single surgery,surgery combined with postoperative chemoradiotherapy cannot significantly improve the overall survival time and disease-free survival time of patients.However,surgery combined with adjuvant chemotherapy can prolong the overall survival time and disease-free survival time of patients.
