Background: To investigate the resilience of non-local medical workers sent to support local medical workers in treating the outbreak of 2019 novel coronavirus disease (COVID-19). Methods: In February 2020, non-local medical workers who had been sent to Wuhan as support staff to respond to the COVID-19 outbreak were asked to complete an online survey composed of the Connor Davidson Resilience Scale (CD-RISC), Hospital Anxiety Depression Scale (HADS) and Simplified Coping Style Questionnaire (SCSQ). Results: Survey responses from 114 non-local medical workers were analyzed. CD-RISC scores were high (67.03 ± 13.22). The resilience level was highest for physicians (73.48 ± 11.49), followed by support staff, including health care assistants, technicians (67.78 ± 12.43) and nurses (64.86 ± 13.46). Respondents differed significantly in the levels of education, training/support provided by the respondent's permanent hospital (where he or she normally works), and in their feelings of being adequately prepared and confident to complete tasks (P < 0.05). Resilience correlated negatively with anxiety (r = −.498, P < 0.01) and depression (r = −.471, P < 0.01) but positively with active coping styles (r = .733, P < 0.01). Multiple regression analysis showed that active coping (β = 1.314, p < 0.05), depression (β = −.806, p < 0.05), anxiety (β = − 1.091, p < 0.05), and training/support provided by the respondent's permanent hospital (β = 3.510, p < 0.05) were significant associated with resilience. Conclusion: Our data show that active coping, depression, anxiety, and training/support provided by the respondent's permanent hospital are associated with resilience. Managers of medical staff should use these data to develop psychosocial interventions aimed at reinforcing the resilience of medical workers during highly stressful and prolonged medical emergencies, as seen during the COVID-19 outbreak.
Objective: To investigate the resilience of medical workers from other provinces to Wuhan to support fighting against 2019 novel coronavirus pneumonia .
Formononetin is a main active component of red clover plants (Trifolium pratense L.), and is considered as a phytoestrogen. Our previous studies demonstrated that formononetin caused cell cycle arrest at the G0/G1 phase by inactivating insulin-like growth factor 1(IGF1)/IGF1R-phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) pathway in MCF-7 cells. In the present study, we investigated the molecular mechanisms involved in the effect of formononetin on prostate cancer cells. Our results suggested that higher concentrations of formononetin inhibited the proliferation of prostate cancer cells (LNCaP and PC-3), while the most striking effect was observed in LNCaP cells. We further found that formononetin inactivated extracellular signal-regulated kinase1/2 (ERK1/2) mitogen-activated protein kinase (MAPK) signaling pathway in a dose-dependent manner, which resulted in increased the expression levels of BCL2-associated X (Bax) mRNA and protein, and induced apoptosis in LNCaP cells. Thus, we concluded that the induced apoptosis effect of formononetin on human prostate cancer cells was related to ERK1/2 MAPK-Bax pathway. Considering that red clover plants were widely used clinically, our results provided the foundation for future development of different concentrations formononetin for treatment of prostate cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
