Scoping review of application effects of self-help intervention model in adult patients with depression / 中国实用护理杂志

Objective:To review relevant research on the application of self-help intervention model in adult depression patients, analyze the main characteristics and application effects of self-help intervention model, in order to provide reference for related research in this field.Methods:According to the methodological framework of the scope review, searched 12 Chinese and English databases including CNKI, Wanfang, PubMed, Web of Science, etc. from the establishment of the database until April 20, 2021, and sorted and analyzed the obtained documents according to the inclusion and exclusion standards.Results:A total of 45 documents were included, of which only 5 were from China; the included studies were mainly based on the Internet platform, using cognitive behavioral therapy, reading therapy, acceptance and commitment therapy, and problem-solving therapy for intervention; the duration of the intervention was 3 weeks to 4 months, participants complete an intervention module or read a specified number of chapters every 3 to 7 days on average, and receive regular guidance and supervision from the intervention facilitator every 1-2 weeks. The total contact time with the facilitator was 80-160 minutes. Various modes of self-help intervention based on the Internet could effectively improve the negative emotions of patients with depression.Conclusions:The self-help intervention model has shown good results in the treatment of patients with depression, but there is a lack of local intervention research in China, and there is no clear standard for the number of interventions and the length of the intervention guide. Under the general trend of "Internet + medical health", it is necessary to actively construct a self-help intervention model for depression with Chinese cultural characteristics, and form a systematic and standardized intervention strategy to address the many obstacles in time, location, resources and cost of people with depression, and finally achieve the purpose of improving the patients′ depressive symptoms and helping them to restore their social functions.

Resilience / 中南大学学报(医学版)

OBJECTIVES@#There are almost one million families who lost their only child in China, and 65.6% of them had severe and long lasting depression and needed timely psycho-intervention. This study aims to explore the relationship among resilience and its influential factors, and to compare their effect on depression.@*METHODS@#A total of 212 only-child loss person in 9 administrative regions in Changsha were assessed by using Connor-Davidson Resilience Scale, Zung Self-rating Depression Scale, Simplified Coping Style Questionnaire, Simplified Eysenck Personality Questionnaire, Social Support Rating Scale, and General Self-efficacy Scale. A hypothetical model was tested based on Kumpfer resilience framework and stress-coping theory.@*RESULTS@#The influential factors of resilience were: positive coping (the total effect value was 0.480), support utilization (the total effect value was 0.359), neuroticism (the total effect value was -0.326), negative coping (the total effect value was 0.279), extraversion (the total effect value was 0.219), and objective support (the total effect value was 0.077). The process of individual-environment interaction showed a greater impact on resilience, which had a direct effect on depression (the total effect value was -0.344, 67.1%), and also indirect effect through self-efficacy (the total effect value was -0.169). The total effect of resilience accounted for 20.1% of the total effect of all variables.@*CONCLUSIONS@#Resilience mainly impacts depression directly, and can negatively predict depression in only-child loss parents. Resilience, located before self-efficacy, is a significant stress mediating variables. Personality traits and support utilization indirectly impact resilience via negative and positive coping. The key to promote the reorganization of resilience is the process of individual-environmental interaction, involving support utilization, positive coping, and some sorts of negative coping strategies, which plays an important role in developing a resilience intervention program and can improve the depression of the only-child loss person.

Research progress in the relationship between depression and survival outcome in patients with lung cancer / 中南大学学报(医学版)

In recent years, with the high incidence of lung cancer and mortality, the disease-relevant mental health problems such as depression began to attract attention. A growing number of studies have also begun to hypothesize and confirm the relationship between depression and survival or mortality in patients with lung cancer, and have made some progress in basic research, prospective cohort research and intervention research. In basic research, cancer can cause depression due to mediating the production of inflammatory factors, and the genotype of tumor epidermis growth factor receptor (EGFR) can explain the high mortality and risk of depression in patients with lung cancer from a certain point of view. Different studies in prospective cohort studies argue that depression is an important predictor of survival in patients with lung cancer and need to be further studied. In the aspect of intervention research, although some studies have confirmed the potential of antidepressants in anti-tumor oxidative therapy, there is no enough evidence in psychological intervention and drug intervention to prove their effectiveness in improving the survival outcome of lung cancer. In the future, it is necessary to further explore the possible mechanisms for antidepressants and psychological intervention to improve the survival time of the patients.

Mediation role of self-efficacy between social support and depression of only-child-lost people / 中南大学学报(医学版)

Objective:To investigate the relationship between social support and depression of only-child-lost (OCL) people,and the mediation role of self-efficacy in this relationship.Methods:By stratified cluster sampling,214 OCL people were enrolled,with 80 males and 134 females,ages from 49 to 83 years old.They were assessed by General Self-Efficacy Scale,Social Support Rating Scale,and Self-rating Depression Scale.Results:Univariate analysis showed that there were significant differences in age groups (t=2.85,P＜0.05),with or without spouse (t=5.62,P＜0.05),family location (t=3.95,P＜0.05),per capita monthly income (F=3.48,P＜0.05) among the social support scores.There was significant difference between the per capita monthly income and self-efficacy scores in QCL people (F=5.46,P＜0.05).Correlation analysis showed self-efficacy and social support were positively correlated (r=0.26,P＜0.01).Self-efficacy (r=-0.59,P＜0.01) and social support (r=-0.59,P＜0.01) negatively correlated with depression in OCL people.Self-efficacy partially mediated the relationship between social support and depression.Conclusion:The person who is ＜60 years old,with spouse and the high per capita monthly income,and lives the rural area,would have high social support levels among QCL people.The person who has high per capita monthly income would have high self-efficacy.Self-efficacy is one of the direct prediction for depression,and plays an indirect role between social support and depression.Intervention of depression among OCL people could be applied to change their cognition,and to enhance their self-efficacy.

An 8-week group positive psychotherapy intervention on depression associated self-efficacy and subjective well-being in female nursing students / 中国心理卫生杂志

Objective:To explore the effects of eight-week group positive psychotherapy intervention on de-pression associated self-efficacy and subjective well-being in female nursing students.Methods:Totally 74 female nursing students with mild to moderate depression [the score of Beck Depression Inventory (BDI-Ⅱ)was 14 to 28]were selected from three nursing colleges of Changsha.They were randomly divided into two groups,40 in the control group and 34 in the intervention group.Samples in the intervention group were given the eight-week group positive psychotherapy,while the control group was given nothing (the control group could receive the intervention when the intervention was proved to be effective or the control group needed treatments).The General Self-efficacy Scale(GSES)and Index of Well-being(IWB)were used to get the outcome of female nursing students'self-effica-cy,subjective well-being at baseline,the time after the intervention,3 month follow-up,6 month follow-up.Results:The interactive effect between group and time of self-efficacy,subjective well-being were statistically significant (Ps0.05).At the end of the intervention,3 month follow-up and 6 month follow-up,the GSES score and IWB score in the intervention group were higher than those in the control group (Ps <0.05).Conclusion:Eight-week group positive psychotherapy could improve self-efficacy and subjective well-being of female nursing students who have mild to moderate depressive symptom.This intervention also has a long-term effect.

Role of K(Ca)3.1 channel in proliferation and migration of rat vascular smooth muscle cells of the proliferative phenotype / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the role of K(Ca)3.1 channel in the proliferation and migration of rat vascular smooth muscle cells of the proliferative phenotype.</p><p><b>METHODS</b>Rat vascular smooth muscle cells (VSMCs) were cultured with tissue adhesion method. The morphological characteristics of the fist and ninth passages of VSMCs were observed with light and electron microscopy and immunocytochemistry. The expressions of K(Ca)3.1 channel mRNA and protein in the cells were detected using RT-PCR and immunocytochemistry, respectively. MTT and transwell assay were employed to assess the effect of the K(Ca)3.1 channel blocker TRAM-34 on the proliferation and migration of VSMCs.</p><p><b>RESULTS</b>The first and ninth passages of VSMCs showed morphological characteristics of contractile and proliferative phenotypes, respectively. Compared with the first- passage cells, the ninth-passage VSMCs exhibited significantly increased K(Ca)3.1 channel mRNA and protein expressions with enhanced cell proliferation and migration (P<0.01), which was inhibited by the application of TRAM-34 (P<0.01). TRAM-34 produced no obvious effect on the first-passage VSMCs.</p><p><b>CONCLUSION</b>Upregulated expression of K(Ca)3.1 channel can promote the proliferation and migration of rat VSMCs of the proliferative phenotype.</p>
