Résumé
Objectives:To design a self-control training program based on the recent findings of self-control and self-regulation after taking full consideration of the unique characteristics of depression disorder,with an emphasis on behavioral activation and reinforcement.Methods:Totally 46 students who were diagnosed with major depression were randomly assigned to one of the two groups:Group 1 (n =23),and Group 2 (n =23).Participants in the Group 1 received 24-week self-control training program,as compared to Group 2 who received only baseline and post-24-week-intervention measurements,the measurements included Self-control Scale (SCS) and Beck Depression Inventory (BDI-Ⅱ).The self-control training included eight-week training modules and 16-week consolidation module.Results:In Group 1,the SCS scores were higher in post-intervention than in baseline measurement [(38.0 ± 6.3) vs.(34.7 ± 8.2),P ＜ 0.01],and the BDI-Ⅱ scores were lower in post-intervention than in baseline measurement [(19.0 ± 6.1) vs.(21.8 ± 4.8),P＜0.01] in Group 1.Whereas in Group 2,there were no significant differences between baseline and post-24-week-intervention measurements of SCS and BDI-Ⅱ scores (Ps ＞0.05).Conclusion:The study provides new evidence for the self-regulation model of depression.Self-control training could be an effective intervention strategy for the treatment of depression.
Résumé
Pulsed electromagnetic field (PEMF), a non-invasive physical treatment modality, is now used clinically to promote bone formation for osteoporosis. The patients after ectomy of ovarian cancer are easily complicated with osteoporosis. However, the safety parameters of PEMF treatment for the osteoporosis patients after resection of ovarian cancer remain unknown. Therefore, this study was designed to examine the effect of different frequency of PEMF on the proliferation, apoptosis and migration of human ovarian cancer cells (SKOV3 cells). Cultured SKOV3 cells were exposed to PEMF stimulation daily with radiation of 8 Hz, 16 Hz, 32 Hz and 64 Hz, respectively. We used sinusoidal waves with strength of 1 mT, twice a day with an interval of 12 hours. An exposure to the waves lasted 30 minutes, for 3 days, with those no PEMF stimulation serving as the control. The proliferation of cells was detected using EdU assay, and the apoptosis of cell was assessed with Annexin V-FITC fluorescence. The migration of cells was measured with the scratch wound assay. The data showed that exposure to PEMF of 1 mT, 8 Hz for 3 days could significantly inhibit the proliferation of SKOV3 cells and induce the apoptosis of the cells. The migrated distance and number were increased by 1 mT, 8 Hz or 32 Hz PEMF stimulation, but decreased by 1 mT, 16 Hz treatment. The results suggested that we should be careful about the safety of PEMF treatment and strictly choose the optical parameters in preventing or treating the osteoporosis of the patients after resection of ovarian cancer.
