Objective:To explore the application effect of the multidisciplinary diagnosis and treatment nursing in improving postoperative anxiety and depression and quality of life in patients with lateral skull base tumor, so as to provide a constructive template for the multidisciplinary diagnosis and treatment nursing.Methods:This was a prospective cohort study design. A total of 100 patients who underwent lateral skull base tumor surgery in Shandong Second Provincial General Hospital from January 2021 to April 2022 were selected as the research objects. The patients were divided into observation group and control group by random digits table method with 50 cases in each group. The control group was given routine nursing care after operation of lateral skull base tumor and routine follow-up management. The observation group received the multidisciplinary diagnosis and treatment nursing on the basis of the control group. The intervention time was 3 months. The psychological state and quality of life of the two groups before and after intervention were evaluated by Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Short Form Health Questionnaire (SF-36).Results:There was no significant difference in SAS, SDS, and SF-36 scores before intervention between the two groups ( P>0.05). The scores of SAS, SDS and SF-36 after the intervention were (44.58 ± 5.61), (41.66 ± 8.48), (75.66 ± 13.65) points in the observation group, and (50.86 ± 4.91), (45.80 ± 9.32), (68.43 ± 14.34) points in the control group, there were statistically significant differences between the two groups( t values were -5.95, -2.32, 2.58, all P<0.05). Conclusions:The multidisciplinary diagnosis and treatment nursing can significantly improve anxiety, depression and quality of life of patients with lateral skull base tumor after surgery.

ObjectiveTo explore the effect of home visit based on empowerment education on psychotic symptoms， self-management ability and well-being of schizophrenia patients in home rehabilitation. MethodsA total of 87 cases of schizophrenia patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） and were recovering at home in Caiba town， Yibin city from January to July 2021 were selected by random sampling method as research subjects. They were divided into experimental group （n=43） and control group （n=44） according to the random number table method. The two groups received routine family visits， and the experimental group received family visits based on empowerment education. The intervention cycle of the two groups was 6 months. Before and after the intervention， the severity of psychotic symptoms， self-management ability and well-being of the patients in the two groups were assessed with the Brief Psychiatric Rating Scale （BPRS）， the Schizophrenia Self-Management Instrument Scale （SSMIS） and the Index of Well-Being Scale （IWB）. ResultsAfter intervention， the intra group comparison showed that the BPRS score in the experimental group was lower than that before the intervention （t=4.550， P<0.01）， the SSMIS scores in both groups were higher than those before intervention （t=-17.107， -6.367， P<0.01）， and the IWB score in the experimental group was higher than that before intervention （t=-9.239， P<0.01）. The comparison between groups showed that the BPRS score of the experimental group was lower than that of the control group， and the SSMIS and IWB scores were higher than those of the control group （t=-3.899， 10.564， 9.690， P<0.01）. ConclusionThe implementation of family visit based on empowerment education may help to improve the psychotic symptoms of home rehabilitation schizophrenia， and improve their self-management ability and well-being.

Objective:To establish a nomogram model for predicting the risk of coronary artery disease in elderly patients with acute myocardial infarction (AMI).Methods:The clinical data of elderly patients with AMI who underwent coronary angiography in the department of cardiology of Cangzhou Central Hospital from July 2015 to March 2020 were analyzed, including age, gender, smoking history, underlying diseases, family history, blood pressure, left ventricular ejection fraction (LVEF), and several biochemical indicators at admission, such as total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), lipoprotein [Lp(a)], apolipoproteins (ApoA, ApoB), ApoA/B ratio, total bilirubin (TBil), direct bilirubin (DBil), indirect bilirubin (IBil), fasting blood glucose (FBG) and uric acid (UA). Patients were divided into model group (2 484 cases) and validation group (683 cases) according to the ratio of 8∶2. According to Gensini score, the model group and validation group were divided into mild lesion group (0-20 points) and severe lesion group (≥81 points). The differences of each index between different coronary lesion degree groups were compared. Lasso regression and Logistic regression were used to analyze the risk factors of aggravating coronary lesion risk in elderly patients with AMI, and then the nomogram prediction model was established for evaluation and external validation.Results:① In the model group, there were significant differences in the family history of coronary heart disease, FBG and HDL-C between the mild lesion group (411 cases) and the severe lesion group (417 cases) [family history of coronary heart disease: 3.6% vs. 7.7%, FBG (mmol/L): 5.88±1.74 vs. 6.43±2.06, HDL-C (mmol/L): 1.48±0.69 vs. 1.28±0.28, all P < 0.05]. In the validation group, there were significant differences between the mild lesion group (153 cases) and the severe lesion group [132 cases; FBG (mmol/L): 5.58±0.88 vs. 6.85±0.79, HDL-C (mmol/L): 1.59±0.32 vs. 1.16±0.21, both P < 0.05]. ② Lasso regression analysis showed that family history of coronary heart disease, FBG, and HDL-C were risk factors of coronary artery disease in elderly patients with AMI, with coefficients 0.118, 0.767, and -0.558, respectively. Logistic regression analysis showed that FBG [odds ratio ( OR) = 1.479, 95% confidence interval (95% CI) was 1.051-2.082, P = 0.025] and HDL-C ( OR = 0.386, 95% CI was 0.270-0.553, P < 0.001] were independent risk factors of coronary artery disease in elderly patients with AMI. ③ According to the rank score of FBG and HDL-C, the nomogram prediction risk model of aggravating coronary artery disease degree was established for each patient. It was concluded that the risk of coronary artery disease in elderly people with higher FBG level and (or) lower HDL-C level was significantly increased. ④ The nomogram model constructed with the model group data predicted the risk concordance index (C-index) was 0.689, and the C-index of the external validation group was 0.709. Conclusions:FBG and HDL-C are independent risk factors for aggravating coronary artery disease in elderly patients with AMI. The nomogram model of aggravating coronary artery disease in elderly patients with AMI has good predictive ability, which can provide more intuitive research methods and clinical value for preventing the aggravation of coronary artery disease in elderly patients.
