Objective To explore influence of comfort care on life quality of breast cancer patients undergoing chemotherapy. Methods Hospitalized breast cancer patients(80 eases) after modified radical mastectomy were selected by convenience sampling method.They were randomly divided into the intervention group and the control group.The control group received conventional care.The intervention group was given comfort care based upon conventional care.The quality of life questionnaire-core 30 (QLQ-C30) by European organization for research and treatment of eancer(EORTC),hospital anxiety and depression scale (HADS) and self-designed questionnaire of satisfaction degree with nursing job were adopted for evaluation of the two groups. Results There was no significant difference in the life quality of patients between two groups before intervention (P＞0.05),but statistical difference was seen after intervention (P＜0.05).The incidence rate of depression and anxiety after the intervention in the intervention group was significantly lower than that of the control group (P＜0.05) and the satisfaction degree with nursing job was significantly higher (P＜0.05). Conclusions Comfort nursing intervention can improve the quality of nursing service,reduce anxiety and depression,improve the life quality of patients.

Objective To investigate the status of patient safety culture cognition and safety nursing behavior among nurses and examine the influence of patient safety culture cognition on safety nursing behavior of nurses using structural equation model. Methods A total of 350 clinical nurses were recruited in a hospital in Dalian with multi-stage sampling method. Patient Safety Culture Assessing Scale, Safety Behavior Scale were delivered to the investigation object. Results The mean score of the patients safety culture was 4.09±0.47, which was above average;the total score of nurses′safety nursing behavior was 4.74 ± 0.31, which was at high level; the causality model of patient safety culture cognition and the safety nursing behavior was accepted (path coefficient=0.35,P<0.01). Conclusions Nurses′ patient safety culture cognition has a significant impact on safety nursing behavior. Hospital should cultivate the awareness of the patient safety culture, so as to promote the safety nursing behavior.

Objective To explore the application of lentil lectin‐reactive alpha‐fetoprotein ratio (AFP‐L3% ) applied in the dif‐ferential diagnosis between hepatitis B infection of primary liver cancer and benign liver disease .Methods We included 108 cases of chronic HBV infection ,including 50 cases of primary liver cancer ,42 cases of cirrhosis ,16 cases of chronic hepatitis .Chemilumines‐cence detection was used to detect alpha‐fetoprotein (AFP) and AFP‐L3 content ,AFP‐L3 and the ratio of AFP (AFP‐L3% ) was calculated .Results AFP≥400 ng/mL as primary liver cancer diagnostic threshold ,the sensitivity and specificity were 36% ,84% , when used AFP‐L3% ≥ 10% as primary liver cancer diagnostic threshold ,the sensitivity and specificity were 62% ,83% . Conclusion AFP‐L3% is a better clinical indicator to distinguish between primary liver cancer and benign liver disease .AFP‐L3%can be used as a clinical indicator to differential diagnosis between HBV infection of primary liver cancer and benign liver disease .
