RESUMEN
Objective:To explore the peer support experience of newly graduated nurses during standardized training period.Methods:Using phenomenological qualitative research methods and purposive sampling, from April to December 2020, 32 new nurses who participated in the standardized training peer support program in the Affiliated Hospital of Yangzhou University were selected. Semi-structured interview was conducted and Claizzi content analysis method was used to analyze the data.Results:Peer support during the standardized training of new graduated nurses could be summarized into four major themes and eleven sub-themes. Theme 1: cognition and attitude (emotional security, adaptive guidance, recognition of the value of peer support, positive intention to support). Theme 2: peer support needs (department-related information needs; knowledge and skills experience needs; emotional communication needs; career growth support needs). Theme 3: peer support experience (adaptive behavior changes, cognitive and emotional changes, differences in perceived expectations of supporters and support effects).Conclusions:During the standardized training, we should attach importance to the important supporting role of peer support for new nurses. By building a peer support platform for new nurses and broadening experience exchange channels, we can enhance the positive experience of peer support, so as to promote the role adaptation and career growth of new nurses.
RESUMEN
<p><b>OBJECTIVE</b>To study the effect of Panax notoginseng saponins (PNS) on expression of alpha-aecretase mRNA in the brains of senescence-accelerated SAMP8 mice.</p><p><b>METHOD</b>SAMP8 mice were randomly divided into the control group, the PNS high-dosage group (200 mg x kg(-1)), the PNS low-dosage group (100 mg x kg(-1)) and the huperzine A group (0.3 mg x kg(-1)), with eight mice in each group. The control group and each administration group were orally administered with the same volume of double distilled water once for consecutively two months. The expression of alpha-secretase (ADAM 9, ADAM10, ADAM17) mRNA was assayed by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR).</p><p><b>RESULT</b>The expression of ADAM9 mRNA in PNS high-dosage group and huperzine A group were significantly higher than that of the control group (P < 0.05). The expression of ADAM10 in the PNS high-dosage group, the PNS low-dosage group and the huperzine A group showed no significant difference from the control group.</p><p><b>CONCLUSION</b>PNS can up-regulate expressions of ADAM9 mRNA and down-regulate expressions of ADAM10 mRNA in the brains of SAMP8 mice.</p>
