RESUMO
Objective To explore the efficacy of the resolving depression and tranquilizing herbal sachets in alleviating sleep disorders of soldiers in naval vessels. Methods Fifty-nine soldiers with sleep disorders (PSQI scale score ≥8 and SAS scale score ≥50) were selected before training at sea, and were randomly divided into sachet treatment group, mindfulness meditation group and control group. During the training period, the sachet treatment group was given traditional Chinese medicine sachet treatment, the mindfulness meditation group was trained in mindfulness meditation, and the control group was not given any intervention. Results Compared with the control group, the PSQI and SAS scores of soldiers in both the experimental sachet treatment group and the positive meditation group were significantly improved; compared with the pre-intervention data, the PSQI and SAS scores of both the positive meditation group and the sachet treatment group were significantly decreased, and the degree of decrease was comparable. Conclusion The homemade improving depression and tranquilizing TCM sachets have the effect of alleviating the sleep disorders of naval troops served on vessels, which is equivalent to mindfulness meditation. It is easy to use and operate, which is suitable for promotion in the military.
RESUMO
Objective To observe the impacts of sulforaphane on proliferation, apoptosis and Wnt/β-catenin pathway of cultured retinoblastoma cells. Methods Retinoblastoma Y79 cells were cultured with varying concentrations of sulforaphane (10, 20, 40 mg/L) for 24 and 48 h. Cell proliferation and apoptosis were measured by CCK8 assay and flow cytometry. Apoptosis related proteins Bax and Bcl-2, as well as the expression levels of related proteins in Wnt/β-catenin signaling pathway were determined using Western Blot. Results Sulforaphane suppressed cell proliferation and stimulate apoptosis (12.47％ ± 2.24％, 24.63％ ± 3.44％, 57.49％ ± 5.41％ vs. 3.47％ ± 0.74％) in a dose- and time-dependent manner, respectively. Furthermore, 40 mg/L of sulforaphane increased the expression of Bax (0.57 ± 0.03 vs. 0.12 ± 0.01), but decreased the Bcl-2 (0.16 ± 0.01 vs. 0.81 ± 0.03) protein expression. The results of Western Blot displayed that sulforaphane decreased the expression levels of Wnt (0.19 ± 0.01 vs. 0.74 ± 0.02), β-catenin protein (0.22 ± 0.02 vs. 0.82 ± 0.03), indicating that sulforaphane can inhibit the activation of Wnt/β-catenin signaling pathway. Conclusions The sulforaphane could inhibit the proliferation and induce the apoptosis of retinoblastoma Y79 cells, probably regulating by the Wnt/β-catenin signaling pathway.
