Objective:To explore the application of nursing intervention based on the capability, opportunity, motivation-behavior model (COM-B) in stroke patients during the rehabilitation period.Methods:Using the convenience sampling method, 146 stroke patients admitted to the First Affiliated Hospital of Zhengzhou University from February 2021 to February 2024 were selected as the research objects. According to the admission time sequence, they were divided into the COM-B group and the routine group, with 73 cases in each group. The routine group received routine nursing measures, and the COM-B group was intervened with the COM-B intervention, both for 3 months. The scores of the Health Education Self-Management Scale for Stroke Patients (HES-SP), the Exercise of Self-Care Agency Scale (ESCA), the Fugl-Meyer Assessment (FMA), and the Barthel Index of the two groups before and after the intervention were compared.Results:Finally, 72 patients in the COM-B group and 71 patients in the routine group completed the study. After 3 months of intervention, the scores of ESCA, HES-SP, FMA, and the Barthel Index of the two groups were all higher than those before the intervention, and the scores of COM-B group were all higher than those of the routine group, and the differences were statistically significant ( P<0.05) . Conclusions:The application of the COM-B intervention in stroke patients can improve patients' healthy behaviors and self-care abilities, and enhance their limb motor function and activities of daily living abilities, with a good application effect.

Objective To investigate the effects of salinomycin on the cell proliferation and epithelial-mesenchymal transition (EMT) of MCF-7 mammosphere (MCF-7 MS). Methods Breast cancer MCF-7 cells were cultured in suspension in serum-free medium to obtain MCF-7 MS. The cell viability of MCF-7 MS cells treated with serial concentrations of 0, 10, 30, 100, 300, 1 000, 3 000 and 10 000 nmol/L of salinomycin for 24 hours were detected by CCK-8 assay. The half maximal inhibitory concentration (IC50) was calculated. Western blot analysis was performed to detect the expression levels of E-cadherin and Snail in MCF-7 MS cells treated with 30 nmol/L and 60 nmol/L salinomycin. The same capacity of DMSO was added to MCF-7 MS as control group. The xenograft tumors from MCF-7 MS transplant mice were divided into control group (the same capacity of normal saline) and salinomycin group (5 mg/kg salinomycin), then the expressions of E-cadherin and Snail were dectected by immunohistochemical staining. Results With the increased concentration of salinomycin, the cell survival rate of MCF-7 MS cells decreased (P<0.05). The IC50 after 24 h-treatment was 989 nmol/L. Both 30 and 60 nmol/L of salinomycin increased the expression of E-cadherin and decreased the expression of Snail compared with control group. In addition, 60 nmol/L treatment group showed more significant effect (P<0.05). In xenograft tumors from MCF-7 MS transplant mice, the expression of Snail decreased, and E-cadherin increased in salinomycin treatment group compared with control group (P<0.01). Conclusion Salinomycin can inhibit the cell proliferation and EMT in MCF-7 MS cells, which is a potential drug to target cancer stem cells.
