Résumé
Objective To learn the willingness to engage in elderly care among nursing students in junior college in order to provide the basis for the training of geriatric nursing staff.Methods Totally 1 1 76 junior college nursing students in Ningbo were selected by stratified sampling method and were investigated with a questionnaire based on the theory of planned behavior.The willingness and plan to engage in elderly care among the students were analyzed.Results Fifty six percent of the nursing students would like to work in geriatric nursing.The average score of behavioral attitude,subjective norm,and perceived behavior control were (52.1 2 ±9.52),(1 6.42 ±6.21 ),and (31 .54 ±7.94).The regression analysis showed that the score of behavior attitude (β=0.1 8),subjective norm (β=0.35 ),and perceived behavior control (β=0.25 )were the factors influencing the willingness to work in geriatric nursing.Different major,grade, experience in elderly care and knowledge had different attitude and behavior in the willingness to engage in elderly care work(P <0.05).There were positive correlations among behavioral attitude,subjective norm,perceived behavior control and behavior intention (P <0.01 )Conclusion The investigation suggested that training nursing staff achievements previews in this area.Nursing students in higher vocational colleges have good professional intention in the work of geriatric nursing work.
Résumé
<p><b>OBJECTIVE</b>To investigate the effect of nitric oxide (NO)-cyclic guanosine monophosphate (cGMP) pathway on cochlear sensitivity. Methods Ten groups of guinea pigs were treated with the following solutions by whole cochlear perfusion for 2 hours: (1) Artificial perilymph; (2) L-arginine; 93) Ca(2+)-ATPase inhibitor; (4) Ca(2+)-ATPase inhibitor + L-arginine; (5) Ca(2+)-ATPase inhibitor + cGMP; (6) Ca 2+ ATPase inhibitor + L-arginine + Non-selective NOS inhibitor; (7) eNOS inhibitor; (8) eNOS inhibitor + Ca(2+)-ATPase inhibitor; (9) eNOS inhibitor + Ca(2+)-ATPase inhibitor + L-arginine; (10) eNOS inhibitor + Ca(2+)-ATPase inhibitor + L-arginine + nNOS inhibitor. The compound action potential (CAP) and cochlea microphonics (CM) were measured to assess the changes of cochlear sensitivity. After the perfusion, the cochleae were harvested and prepared for transmission electron microscopy.</p><p><b>RESULTS</b>The average threshold shift of CAP after perfusion Ca(2+)-ATPase inhibitor was 28.5 dB, and it was improved in group 4 with 9 dB by L-arginine, similar with group 5. The threshold shift of CAP in group 8 was 42.5 dB, and it decreased in group 9 by L-arginine, on this foundation nNOS inhibitor was added, increased threshold shift of CAP was 6.5 dB, similar with group 8. The results indicated that L-arginine could rivalry the role of Ca(2+)-ATPase inhibitor through the path of NO-cGMP. Transmission electron microscopy showed that Ca(2+)-ATPase inhibitor + L-arginine combined administration resulted in less vacuolization in out hair cell than that treated with Ca(2+)-ATPase inhibitor only.</p><p><b>CONCLUSIONS</b>The NO-cGMP pathway could regulate cochlear sensitivity; L-arginine may improve the function of Corti's organ via nNOS, and they indicate an important role of supporting cells in the modulation of cochlear function.</p>
