Objective To investigate and analyze the perioperative nursing of patients with breast cancer, and explore the effectiveness of the application of mind map in perioperative nursing care of patients with breast cancer. Methods The cluster sampling method was employed, and 265 patients with breast cancer receiving radical mastectomy treatment from department of general surgery of the First Affiliated Hospital of Liaoning Medical University were gathered according to the inclusion and exclusion criteria. 137 cases were assigned to test group (May 2014 to April 2015), and 128 cases were assigned to control group (May 2013 to April 2014 ). Nursing work was improved by establishing research group, discussing the design of perioperative nursing mind map and applying mind maps. Effect was evaluated by evaluating the incidence of postoperative complications in patients with breast cancer, the quality of patient′s life and the patient′s satisfaction. Results The incidence of bleeding, seroma, flap necrosis, upper extremity swelling and other postoperative complications of patients with breast cancer in test group was 26.28%(36/128),and that in control group was 73.44%(94/137). The differences between the two groups were of statistical significance (χ2=58.891, P<0.01). The perioperative survival quality scores of physiology, society/family, emotions, function, additions and total in the test group were (2.43 ± 1.09), (2.64±0.97), (2.85±0.97), (2.43±1.09), (2.22±1.12),(2.34±1.13), and that in the control group were (1.89± 1.09), (1.89 ± 1.06), (1.78 ± 0.92), (1.89 ± 1.09), (1.76 ± 1.05), (2.00 ± 1.09)respectively. The differences between the two groups were statistically significant (t=4.664-10.829,P<0.01). The proportion of patient satisfaction in test group was 94.89%(130/137),and that in control group was 82.03%(105/128), respectively. The differences between the two groups were statistically significant (χ2=10.900, P < 0.01). Conclusions Application of mind map in nursing intervention is able to help nurses to grasp the key content and direction of perioperative nursing on patients with breast cancer. More importantly, not only can it improved patients′quality of life and reduce the incidence of postoperative complications, but also increases patients′satisfaction.

Objective To investigate the risk factors of cognitive impairment in post-intensive care syndrome patient (PICS-CI).Methods A retrospective study was conducted. The patient who transferred from post-intensive care unit (ICU) to the general ward for more than 7 days, and with the age ≥ 18 years old in the First Affiliated Hospital of Jinzhou Medical University from October 2015 to November 2016 were enrolled. The gender, age, marital status, education, occupation, salary, economic income, smoking, alcohol drinking, previous of history, mechanical ventilation, the length of ICU stay, sedative and delirium, and initial diagnosis were recorded. According to mini-mental state examination (MMSE), the patients were divided into cognitive impairment (CI) group and non-CI group. Univariate analysis was performed to identify the risk factors of PICS-CI, and variables with statistical difference were selected to do multivariate binary logistic regression analysis for the confirmable independence risk factors.Results 104 of the 290 patients developed CI, and the incidence was 35.86%. Univariate analysis showed that the gender, age, education, financial situation, smoking, alcohol drinking, previous of history, mechanical ventilation, the length of ICU stay, sedative and delirium, and initial diagnosis were recorded of ICU were main predictors of PICS-CI patients. It was shown by multivariate binary logistic regression analysis that the age > 60 years old [odds ratio (OR) = 7.523, 95% confidence interval (95%CI) = 2.572-37.851,P = 0.001], mechanical ventilation (OR = 8.773, 95%CI = 2.588-36.344,P < 0.001), sedation (OR = 9.376, 95%CI = 2.661-42.011,P = 0.002), and delirium (OR = 13.201, 95%CI = 2.502-41.433, P < 0.001) were PICS-CI independence risk factors.Conclusions Nurse staffs should strength care and attention on ICU transferred out patients. In order to minimize PICS impairment, special precaution should be implemented according to different aspects.

Objective To evaluate the effectiveness of mindfulness-based stress reduction( MBSR) on anxiety and depression in spouses of breast cancer patients and to analyze the mediating effect of caregiver burden for the training effects. Methods Randomized control trial was used in this research.100 spouses of breast cancer patients were recruited and they were randomized into experimental group or control group. 91 of them completed the study finally (45 in experimental group and 46 in control group). Participants in con-trol group received no intervention,while participants in experimental group received MBSR once a week for 8 weeks. All participants were assessed with the Zarit Caregiver Burden Interview ( ZBI,measuring caregiver burden) ,Beck Depression Inventory( BDI,measuring depression level) and Hamilton Anxiety Scale( HAMA, measuring anxiety level) before and after intervention. Results After 8-week intervention,participants in experimental group got significantly lower total scores of ZBI,BDI and HAMA compared with pretest ((22.31 ±5.76) vs (25.98±6.00),(8.47±3.21) vs (11.87±3.51),(14.98±4.75) vs (17.93±4.65), P<0. 01), while there were no significant differences between posttest and pretest on any score in control group (P>0.05).Caregiver burden played mediating effect in MBSR for improving depression,and mediating effect was 56.6% of the total effect. Conclusion MBSR can effectively improve anxiety and depression with the spou-ses of breast cancer patients,and the caregiver burden is the intermediary variable in the effect of MBSR for improving depression.
