ABSTRACT
With the use of light at different length and intensities, light therapy can regulate the circadian rhythm of the patients with Alzheimer's disease (AD). This paper reviewed the existing domestic and foreign researches, discovered that light therapy improved the sleep quality, cognitive function, and negative emotions, etc., of AD patients, and attracted more and more people's attention. However, some other studies found that light therapy did not significantly improve the sleep quality and cognitive function of AD patients. The specific mechanism is still unclear, and further studies are needed in the future.
ABSTRACT
Objective To develop chemotherapy training system for new nurses in cancer special hospital and to provide related references.Methods The initial chemotherapy training system for new nurses in cancer special hospital was developed by literature review.Two rounds of expert consultation were conducted among 22 experts from 14 cities in China via Delphi Technique to finalize the training system.Results The recovery rates were 100.00％ and 90.90％,and the authority coefficients were both 0.82,coordination coefficients of two rounds of consultation were statistically significant by chi-square test (P＜0.01),the coefficient of variation of each item ranged from 0.00 to 0.21 in the second round.The chemotherapy training system consisted of 6 first-level indicators,13 second-level indicators and 50 third-level indicators.Conclusion The study methods were scientific,experts had high level of enthusiasm and authority,and had agreed opinions for each indicator of the developed chemotherapy training system for new nurses in cancer special hospital which can be used for training new nurses.
