Objective:To explore the mediating role of interdisciplinary cooperation ability between the level of hospice care practice and difficulty degree of hospice care for medical staff, in order to improve the quality of hospice care services for medical staff, and to provide evidence for relevant managers to formulate effective measures to reduce the implementation of hospice care difficulties.Methods:This study was a cross-sectional survey. Using convenience sampling method, the general data questionnaire, Palliative Care Difficulties Scale (PCDS), Palliative Care Self-Report Practice Scale (PCPS) and Modified Index of Interdisciplinary Collaboration (MIIC) were used to investigate 362 medical staff in all hospice care institutions of Shiyan City from July to August 2022.Results:The total score of PCDS in 362 medical staff was (40.58±13.44) points, (67.47 ± 12.50) points for PCPS and (108.36 ± 21.46) points for MIIC. There was a positive correlation between the total score of MIIC and PCDS ( r=0.500, P<0.01). The total score of PCPS was negatively correlated with the total score of MIIC ( r=-0.337, P<0.01) and the total score of PCDS ( r=-0.189, P<0.01). The interdisciplinary cooperation ability of medical staff in hospice care had a complete mediating effect between the level of practice and the degree of difficulty (Effect value=-0.190, 95% CI-0.274 to -0.126), and the mediating effect accounted for 98.5% of the total effect value. Conclusions:The practice level of hospice care can not directly affect the implementation of the difficulty degree, but by taking active measures to improve the interdisciplinary cooperation ability, so as to enhance the practice level, and then reduce the implementation of hospice care difficulty degree.

Objective:To explore the application effect of staged health education combined with respiratory function exercise in patients undergoing esophageal cancer surgery.Methods:Using the convenient sampling method, a total of 200 patients with esophageal cancer who were admitted to Affiliated Cancer Hospital of Zhengzhou University from February 2019 to February 2020 were selected as the research objects. The patients were divided into the control group (81 cases) and the observation group (119 cases) according to their hospitalization time. The control group was given respiratory function exercise and routine nursing, while the observation group was given staged health education combined with respiratory function exercise on the basis of routine nursing. The cognition level and lung function of patients of the two groups before and 7 days after operation were compared.Results:The levels of vital capacity (VC) , maximum ventilation (MVV) and forced vital capacity in the first second (FEV1) in the observation group were higher than those in the control group at 7 days after operation, and the difference was statistically significant ( P<0.05) . The cognitive score of the observation group was higher than that of the control group at 7 days after operation, and the difference was statistically significant ( P<0.05) . Conclusions:Staged health education combined with respiratory function exercise can improve postoperative cognitive level and lung function of patients with esophageal cancer.

Objective:To explore the influencing factors of postoperative coping style of patients with esophageal cancer.Methods:This study was a cross-sectional study. From July 2018 to July 2020, convenience sampling was used to select 65 patients with esophageal cancer who underwent radical surgery for esophageal cancer in a ClassⅢ Grade A hospital in Henan Province as the research object. The General Information Questionnaire and the Chinese version of the Medical Coping Modes Questionnaire (MCMQ) were used to investigate the patients one day before the patients were discharged. Single factor analysis was used to analyze influencing factors. A total of 65 questionnaires were distributed and 65 valid questionnaires were returned with the valid response rate of 100%.Results:The results of single factor analysis showed that there were statistically significant differences in the confrontation dimension scores of patients with different ages, education levels, and family monthly income per capita ( P<0.05) . There were statistically significant differences in the avoidance dimension scores of patients with different genders and ages ( P<0.05) . There were statistically significant differences in the resignation dimension scores of patients with different ages, occupational status, and family monthly income per capita ( P<0.05) . Conclusions:Age, gender, occupational status, education level, and family monthly income per capita are the influencing factors of postoperative coping style of patients with esophageal cancer. Medical and nursing staff can take targeted intervention measures based on their influencing factors and guide patients to adopt a positive coping style to face the disease.

Objective:To evaluate the relationship between perioperative cardiovascular events and serum transient receptor potential vanilloid 1 (TRPV1), calcitonin gene-related peptide (CGRP) and substance P (SP) concentrations in the patients with diabetic peripheral neuropathy (DPN).Methods:Twenty-eight patients with type 2 diabetes mellitus (DM) complicated by DPN undergoing elective non-cardiovascular surgery under general anesthesia, were enrolled in DPN group, and 28 patients with type 2 DM without DPN were included in DM group.Another 28 nondiabetic patients undergoing non-cardiovascular elective surgery under general anesthesia were selected as control group (C group). The patients were 55 to 81 years old and classified as American Society of Anesthesiologists physical status Ⅱ or Ⅲ, regardless of gender.The development of cardiovascular events during surgery and within 24 h after surgery and use of vasoactive drugs were recorded.Venous blood samples were taken at 30 min before anesthesia induction and 24 h after surgery for determination of the concentrations of TRPV1, CGRP, SP and cardiac troponin I (cTnI) in serum using enzyme-linked immunosorbent assay.Results:Compared with group C, the incidence of perioperative cardiovascular events and utilization rate of vasoactive drugs were significantly increased, the preoperative concentrations of serum TRPV1, CGRP and SP were decreased, and the postoperative concentration of serum cTnI was increased in DM and DPN groups ( P<0.05). Compared with DM group, the incidence of perioperative cardiovascular events was significantly increased, the preoperative concentrations of serum TRPV1, CGRP and SP were decreased, the postoperative concentration of serum cTnI was increased ( P<0.05), and no significant change was found in the utilization rate of vasoactive drugs in DPN group ( P>0.05). The postoperative cTnI concentrations in serum were negatively correlated with the preoperative TRPV1, CGRP and SP concentrations in serum in DPN group ( P<0.01). Conclusion:The increased risk of perioperative cardiovascular events may be related to the decrease in serum TRPV1, CGRP and SP concentrations in DPN patients.
