Objective:To explore the reasons for delayed medical treatment in diabetic foot patients using the health ecology model as a framework.Methods:From November of 2021 to March of 2022, descriptive phenomenological research methods was used in 20 patients with diabetic foot who delayed medical treatment were interviewed face-to-face semi-structured in depth, and the data analysis was carried out using the seven-step method of Colaizzi phenomenology to refine the theme.Results:According to the five levels of the health ecology model, the reasons for delayed medical treatment were summarized into 11 themes, and the reasons for the personal trait layer included foot ulcers are not detected promptly, and the perceptual decline of advanced patients. Behavioral characteristics included lack of knowledge of diabetic foot, negative medical psychology. Reasons for the interpersonal network included insufficient family support and lack of social support; reasons for living and working conditions included high economic pressure, low electronic health literacy, and inconvenient medical treatment; the reasons for the policy environment included uneven medical insurance reimbursement ratios and limited medical conditions.Conclusions:The reason for the delay in seeking medical treatment for diabetic foot patients is multi-layered and systematic, and medical staff need to improve the self-management ability of diabetic patients′ feet from the individual level, and also need to guide patients from the system level on how to obtain the best medical resources.

Objective:To explore the effect of repetitive transcranial magnetic stimulation (rTMS) combined with cognitive behavioral therapies (CBT) on the cognitive function and alcohol craving in patients with alcohol dependence.Methods:From March 2019 to September 2021, a total of 150 patients with alcohol dependence were enrolled and randomly divided into rTMS treatment group (rTMS+ sham CBT, n=41), CBT treatment group (CBT+ sham rTMS, n=34), rTMS+ CBT treatment group( n=36) and control group (sham rTMS+ sham CBT, n=39). At baseline (before treatment), 2nd week, 8th week, 12th week and 24th week, alcohol dependence scale (ADS) was used to evaluate the degree of alcohol dependence, the obsessive compulsive drinking scale (OCDS) was used to assess patients' drinking craving, and Montreal cognitive assessment scale (MoCA) was used to assess the overall cognitive level of patients.SPSS 23.0 statistical software was used to compare the differences of ADS, OCDS and MoCA scale scores of the four groups by repeated measure ANOVA and simple effect analysis. Results:(1)The patients in the four groups were evaluated with ADS scale at baseline, 12th week and 24th week respectively.The interaction of group×time( F=1.279, P=0.279) and the main effect of group were not significant ( F=0.882, P=0.454), and the main effect of time was significant ( F=12.925, P<0.001) .Further simple effect analysis showed that the ADS score of rTMS+ CBT group was lower than that of baseline(14.48±5.70, 10.00±6.51) ( P=0.01) at 24th week.(2)Patients in the four groups were assessed with OCDs scale at baseline, 2nd week, 8th week, 12th week and 24th week, and the interaction of group×time was significant ( F=2.015, P=0.042). Further simple effect analysis showed that the OCDs scores of rTMS group and rTMS+ CBT group at each follow-up time node were lower than those at baseline period (all P<0.05). (3)Patients in the four groups were assessed with MoCA scale at baseline, 8th week, 12th week and 24th week, and the interaction of group×time was not significant ( F=1.660, P=0.106), and the main effect of group and the main effect of time were significant ( F=2.964, P=0.038; F=14.239, P<0.001). Further simple effect analysis showed that the score of MoCA scale in CBT group at the 24th week was higher than that at baseline (21.73±5.81, 24.60±3.98)( P=0.029), the score of MoCA scale in rTMS+ CBT group at the 24th week was higher than that at the 8th week (23.50±6.01, 25.95±2.87) ( P=0.006), and the score of MoCA scale in rTMS group at the 12th week was higher than that in control group (22.08±6.64, 26.64±2.46)( P=0.009). Conclusion:rTMS combined with CBT can be effective in improving alcohol craving and cognitive function in patients with alcohol dependence, and has a good long-term effect.

BACKGROUND: Thyroid transcription factor-1 (TTF-1) has been widely studied in non-small cell lung cancer, which is considered as an independent prognostic factor in patiens with non-small cell lung cancer. However, there are few studies on the prognostic value of TTF-1 in small cell lung cancer (SCLC). The purpose of this study was to explore the relationship between the expression state of TTF-1 and the sensitivity to first-line chemotherapy and prognosis in patients with SCLC. METHODS: A retrospective analysis was made on 234 patients with SCLC who were diagnosed and treated in The Affiliated Hospital of Qingdao University and received platinum-based chemotherapy. The clinical characteristics, treatment and survival of the patients were followed up. Chi χ² test and Logistic regression model were used to analyze the relationship between TTF-1 expression and chemotherapy response rate. Kaplan-Meier method and Cox proportional hazard regression model were used to analyze the effect of TTF-1 expression on survival time of patients. RESULTS: Among the 234 patients, the positive expression of TTF-1 was 188 cases (80.3%), and the negative expression of TTF-1 was 46 cases (19.7%). The objective response rate (ORR) of first-line chemotherapy in patients with positive expression of TTF-1 was higher than that in patients with negative expression of TTF-1 (70.7% vs 47.8%) (χ²=8.681, P=0.003). Logistic regression multivariate analysis showed that the expression state of TTF-1 was an independent predictor of ORR in first-line chemotherapy (OR=0.216, 95%CI: 0.076-0.615, P=0.004), however this difference was only reflected in LS-SCLC. The median progression free survival (PFS) of patients with negative expression of TTF-1 was shorter than that of patients with positive expression (6.9 months vs 9.0 months) (χ²=9.357, P=0.002). The median OS in TTF-1 negative group was shorter than that in TTF-1 positive group (13.3 months vs 20.1 months)(χ²=12.082, P=0.001). CONCLUSIONS TTF-1 expression is an independent predictor of first-line chemotherapy response rate and survival in patients with SCLC, and may become a biomarker to predict the efficacy and prognosis of SCLC.
