BACKGROUND: Psychological factors are a risk factor for the incidence of breast cancer and have a significant impact on patient prognosis. OBJECTIVE: The present study aims to investigate the effects of personalised graded psychological intervention on negative emotion and quality of life in patients with breast cancer. METHODS: A total of 200 patients with breast cancer were randomly divided into two groups: an experimental group (n = 100) and control group (n = 100). Both groups received routine nursing care. The experimental group received personalised graded psychological intervention care, and the control group received routine nursing measures. After 2 months of standard treatment, the patients' quality of life and negative emotions were evaluated using the self-rating depression scale (SDS), self-rating anxiety scale (SAS), social support rating scale (SSRS) and quality of life measurement scale (FACT-B) scoring criteria. RESULTS: There were no significant differences in the general data between the two groups (p > 0.05). Furthermore, there were no significant differences in the SDS, SAS, SSRS and FACT-B scores between the two groups before personalised graded psychological intervention (p > 0.05). After the intervention, the experimental group exhibited an improved nursing effect compared with the control group. The SDS and SAS scores were lower in the experimental group than in the control group (p < 0.05); after the intervention, the SDS and SAS scores were significantly lower in the experimental group than in the control group (p < 0.05). The SSRS and FACT-B scores were higher in the experimental group than in the control group (p < 0.05), and the experimental group's post-intervention SSRS and FACT-B scores were significantly higher than before the intervention (p < 0.05). CONCLUSIONS: The use of personalised graded psychological intervention for the nursing of patients with breast cancer in clinical practice can significantly reduce patients' negative emotions as well as improve positive emotions and quality of life; thus, this method can be popularised in the nursing process.

The height of overburden fissure zone is an important index to study the deformation and failure of overburden, but the existing single index can not reflect the fracture degree of surrounding rock in different space parts of stope. Based on 81505 working face of Baode Mine with typical shallow burial conditions in Shendong, the unification of coal sample damage degree and index RFD (Rock Failure Degree) is completed by laboratory experiments, and a similar model and a numerical model are constructed. Based on the index RFD, the maximum destructive depth in numerical simulation is extracted, and the law of development height of overburden mining fissure zone and its variation with mining height are studied by comparing similar simulation results. The results show that the index RFD can well assess the development characteristics of mining fissure zone under typical shallow burial conditions in Shendong. And the development height of fissure zone continuously with the increase of mining height but the growth rate decreases gradually. The research in this paper provides theoretical support and technical basis for distribution and destruction characteristics of fractured zones, occurrence of rock pressure and safe mining.

Introduction: Cardiovascular ailments threaten human health. In China, the primary cardiovascular diseases include stroke and coronary heart disease, resulting in rising morbidity and mortality rates. Coronary heart disease accounts for 10%-20% of all deaths from cardiovascular diseases. These diseases increasingly affect younger individuals, with the disparity in incidence between urban and rural areas gradually diminishing. Experts predict that cardiovascular diseases will continue to increase through the end of this century and into the next in China. Therefore, it is imperative to implement preventive measures to treat coronary heart disease. This paper explores how family-centered health intervention affects anxiety levels, depression symptoms, and sleep quality among perioperative patients receiving coronary interventional therapy., Methods: The participants for this study received coronary intervention therapy in the researchers' hospital from August 2020 to April 2021. Study participants comprised control and observation groups based on a random number table. Both groups received routine care. However, the observation group received family-centered health interventions. Researchers observed the differences in anxiety and depression scores, self-care ability, sleep quality, and incidence of complications between the two groups before and after the intervention., Results: Following the intervention, the sleep quality of the observation group was better than that of the control group, and the difference was statistically significant. There was no difference in activities of daily living (ADL) scores between the two groups before the intervention. Moreover, there was no significant difference in ADL scores on the first, second, and third postoperative days. The incidence of postoperative arrhythmia and coronary artery restenosis between the two groups showed a statistically significant difference., Conclusions: Family-centered health intervention benefited perioperative patients receiving coronary intervention therapy. It improved patients' mood and sleep quality and demonstrated positive application value.
