Objective:To explore the level of positive psychological capital and its trends in traumatic lower limb amputation patients during the 15 months after surgery, and to identify the time period when the patients' level of positive psychological capital is weak, so as to provide a basis for interventions.Methods:This study was a prospective longitudinal study. Convenience sampling was used to select 143 patients with traumatic lower limb amputation admitted to the Department of Emergency Medicine of the First Affiliated Hospital of Zhengzhou University from January 2021 to November 2022 for the study. General information questionnaire, Positive Psychological-Capital Questionnaire (PPQ) were used on the third postoperative day (T1) , on the day of discharge (T2) , 1 month (T3) , 2 months (T4) , 3 months (T5) , 6 months (T6) , 9 months (T7) , 12 months (T8) , and 15 months (T9) after discharge for a total of nine time points to administer the questionnaire to the patients. One-way repeated-measures ANOVA and plotting of results were performed on the nine time-point data using Graph Pad prism 9.5 software and SPSS 21.0 software, and the data were compared two-by-two using the Bonferroni multiple comparison test.Results:There were 143, 139, 132, 129, 122, 120, 119, 118, and 116 patients who participated in the survey from T1 to T9 time points, with a loss to follow-up rate of 18.88% (27/143) . PPQ scores of 116 traumatic lower limb amputation patients at nine time points were (103.25±9.03) , (108.53±9.32) , (104.38±9.60) , (99.71±9.61) , (95.82±9.55) , (91.49±9.41) , (93.34±9.29) , (93.53±9.14) , (93.62±9.05) , and the mean PPQ scores were lower than the theoretical mean (104) at all time points except T2 and T3 time points. One-way repeated-measures ANOVA showed that the difference in the change in the level of positive psychological capital of patients after traumatic lower limb amputation from postoperative day 3 to 15 months after discharge was statistically significant ( F=990.144, P<0.01) . Bonferroni's multiple comparison test showed that there was no statistically significant difference in two-by-two comparisons between T7, T8, and T9 time points with each other ( P>0.05) , and the rest of the two-by-two comparisons were statistically significant ( P<0.05) . Changes in the total PPQ score and the curves of the self-efficacy dimension, resilience dimension, hope dimension, and optimism dimension scores all showed a trend of a brief increase, followed by a continuous decrease, and then a slow increase to a plateau. Conclusions:Traumatic lower limb amputation patients show a wide range of changes in positive psychological capital levels from postoperative day 3 to 15 months after discharge, with a trend of a brief increase at discharge, followed by a steady decline, and then a slow increase to a plateau. Healthcare professionals should pay dynamic attention to the psychological state and psychological strength of patients after traumatic lower limb amputation and provide targeted interventions at different stages after discharge.

Objective:To explore the effect of positive reinforcement theory-based nursing in patients with acute myocardial infarction undergone percutaneous coronary intervention (PCI) .Methods:Convenience sampling was used to select 107 patients with acute myocardial infarction after PCI in the First Affiliated Hospital of Zhengzhou University from July 2018 to June 2020 as the research object. The patients were divided into the experimental group ( n=54) and the control group ( n=53) by random number table method. The control group was given routine nursing after PCI, while the experimental group was given nursing based on positive reinforcement theory on the basis of the control group. After six months of follow-up, the scores of the Self-management Scale for Patients Undergone Coronary Artery Stent Implantation, the Coronary Revascularization Outcome Questionnaire for Determination of Quality, and the incidence of cardiovascular adverse events were compared between the two groups before and after the intervention. Results:After intervention, The total score and the scores of each dimension of the Self-management Scale for Patients Undergone Coronary Artery Stent Implantation and the scores of each dimension of the Coronary Revascularization Outcome Questionnaire for Determination of Quality of the experimental group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . The incidence of cardiovascular adverse events in the experimental group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Positive reinforcement theory-based nursing can help improve the self-management ability of patients with acute myocardial infarction undergone PCI, reduce the incidence of adverse cardiovascular events, and improve the quality of life of patients.

Objective? To explore the effects of home visit directed by Peplau interpersonal relationship model on negative emotions and medication adherence in elderly bronchial asthma patients. Methods? From May 2015 to May 2017, we selected 90 elderly bronchial asthma patients in the First Affiliated Hospital of Zhengzhou University as subjects by convenience sampling. All of the patients were divided into observation group and control group with the method of random number table, 45 cases in each group. Observation group carried out home visit nursing based on the Peplau interpersonal relationship model for elderly bronchial asthma patients. Control group adopted routine follow-up care. The medication adherence and disease cognition of patients both groups were recorded with the Medication Adherence Report Scale for Asthma (MARS-A) as well as Insight and Treatment Attitude Questionnaire (ITAQ), and the anxiety and depression of patients both groups before and after intervention were assessed with the Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD). We also observed the incidence of bronchial asthma acute attack in patients one year after discharge. Results? When home visit was completed and one year after discharge, the medication adherence of observation group was higher than that of control group, and the score of ITAQ was higher than that of control group and that at discharge with statistical differences (P＜ 0.05). One year after discharge, the incidence of bronchial asthma acute attack of observation group was lower than that of control group with a statistical difference (P＜ 0.05). When home visit was completed and one year after discharge, the scores of HAMA and HAMD of observation group were lower than those of control group with statistical differences (P＜0.05). Conclusions? Home visit directed by Peplau interpersonal relationship model help to reduce the incidence of acute attack of elderly bronchial asthma patients external hospital, relieve the negative emotions and improve disease cognition as well as medication adherence.

Objective? To explore the application of three-dimensional quality assessment model of structure-process-outcome in continued nursing care for elderly patients with lung cancer after operation. Methods? By purposive sampling, 48 elderly patients discharged after radical resection of lung cancer from January to December 2016 were taken as control group and received routine continuous nursing care. Another 51 elderly patients discharged after radical resection of lung cancer from June 2017 to June 2018 were taken as the observation group. Continuous nursing program based on structure-process-outcome quality assessment model was applied for the observation group. The effect of intervention was assessed by using Strategies Used by People to Promote Health (SUPPH) and Quality of Life Questionnaire-30(QLQ-30). Results? At 6 months after discharge, the scores of each dimension of SUPPH scale in the observation group were statistically higher than those in the control group (P＜ 0.05). In the observation group the scores of "physical function", "role function", "social function" and "overall health" of QLQ-30 scale were higher than the control group, the scores of "fatigue", "pain", "insomnia", "lack of appetite", "constipation", and "diarrhea" were all lower than the control group with statistical significance (P＜0.05). Conclusions? The continuous nursing care based on the three-dimensional quality assessment model of structure-process-outcome for elderly patients with lung cancer can help to improve their sense of self-efficacy and quality of life.
