Evaluation of the clinical effect of a multimodal pre-rehabilitation program guided by the behaviour change wheel in elderly women with breast cancer.

BACKGROUND: This study aims to explore the nursing effect of a multimodal pre-rehabilitation programme guided by BCW theory on elderly women patients with breast cancer. METHODS: The participants were divided into two groups. The study group was administered with the pre-rehabilitation model guided by BCW theory; the control group was administered with conventional methods. The rehabilitation effects of the two groups were compared.. RESULTS: The scores of RISC, PTGI and FACT-B were higher in the study group(P < 0.05). The SUPPH score and ROM compliance rate were higher in the study group (P < 0.05) (96% vs 72%). The avoidance score and yield score were lower in the study group(P < 0.05). CONCLUSION: A multimodal pre-rehabilitation program guided by BCW theory can significantly improve the quality of life and functional status of elderly women patients with breast cancer, and its popularisation and application are recommended.

Panduratin A Inhibits Cell Proliferation by Inducing G0/G1 Phase Cell Cycle Arrest and Induces Apoptosis in Breast Cancer Cells.

Because of the unsatisfactory treatment options for breast cancer (BC), there is a need to develop novel therapeutic approaches for this malignancy. One such strategy is chemotherapy using non-toxic dietary substances and botanical products. Studies have shown that Panduratin A (PA) possesses many health benefits, including anti-inflammatory, anti-bacterial, anti-oxidant and anti-cancer activities. In the present study, we provide evidence that PA treatment of MCF-7 BC cells resulted in a time- and dose-dependent inhibition of cell growth with an IC50 of 15 µM and no to little effect on normal human MCF-10A breast cells. To define the mechanism of these anti-proliferative effects of PA, we determined its effect critical molecular events known to regulate the cell cycle and apoptotic machinery. Immunofluorescence and flow cytometric analysis of Annexin V-FITC staining provided evidence for the induction of apoptosis. PA treatment of BC cells resulted in increased activity/expression of mitochondrial cytochrome C, caspases 7, 8 and 9 with a significant increase in the Bax:Bcl-2 ratio, suggesting the involvement of a mitochondrial-dependent apoptotic pathway. Furthermore, cell cycle analysis using flow cytometry showed that PA treatment of cells resulted in G0/G1 arrest in a dose-dependent manner. Immunoblot analysis data revealed that, in MCF-7 cell lines, PA treatment resulted in the dose-dependent (i) induction of p21WAF1/Cip1 and p27Kip1, (ii) downregulation of Cyclin dependent kinase (CDK) 4 and (iii) decrease in cyclin D1. These findings suggest that PA may be an effective therapeutic agent against BC.
