RESUMO
Objective:To investigate the effect of smart air cell mattresses on sleep quality.Methods:Twenty healthy young people were enrolled as subjects, and each subject underwent a four-night polysomnographic monitoring experiment, including two nights each on a smart air cell mattress and a general mattress. The differences in sleep quality were compared by self-assessment of sleep quality, objective sleep indicators, and electroencephalogram (EEG) spectral analysis.Results:In the comparison between the smart air cell mattress and the general mattress, the differences in self-assessment of sleep quality and objective sleep indicators were not statistically significant (all P > 0.05), but the smart air cell mattress had a slight overall advantage. The relative power of EEG in the low-frequency band and the relative power of EEG in the high-frequency band were higher in the subjects with the smart air cell mattress. Conclusions:For the healthy young population, the smart air cell mattress can positively influence sleep quality to some extent, and the change in EEG relative power indicates an increase in sleep depth.
RESUMO
OBJECTIVE@#The study presents an experiment platform to perform ventilation and develop the control strategy for ventilator.@*METHODS@#The software designed by LabVEIW displays and saves data in ventilation support through connecting with data acquisition device and signal processing circuit, which is improved by control strategy in order to achieve the more scientific ventilation.@*RESULTS@#The experiment platform realizes the ventilation support and is close to the data outputted from ventilator.@*CONCLUSIONS@#The platform provides values for ventilation control strategy in development phase.

Objective To evaluate the life quality in front and at the back of the cure of the floating population tuberculosis patients.Methods The SF-36 scale was applied to the new smear-positive pulmonary tuberculosis patient in floating population using face to face interview in Shenzhen 6 districts.The contrast was tuberculosis patient in the population of the household register,the people stayed temporarily in the same term.Results The score of general health(43.36 ± 15.67),vitality(57.96 ± 16.54) and mental health(61.46 ± 14.26) in the floating population was lower than the appraisal result with the population of the household register(49.28 ± 17.85,66.38 ± 17.03 and 66.70 ± 15.12),the people stayed temporarily(45.00 ± 17.22,60.99 ± 16.59 and 63.13 ±13.71 ) (P ＜ 0.05 ).It was still lower than the other two groups after 2 (3) months and 6 (7) months (P ＜ 0.05 ).But the score of social functioning in floating population ( 88.92 ± 14.88 ) was higher than the other two groups (82.62 ± 14.44,68.02 ± 27.30).The change rate of general health ( (76.05 ± 132.82) ％,(69.32 ± 111.98 ) ％and (48.36 ± 101.31 ) ％ ) and social functioning scores( (46.49 ± 85.18 ) ％,( 26.33 ± 50.25 ) ％ and ( 51.09±73.44)％ ) were significant difference in the three groups(x2 =12.088,P=0.002;x2 =11.611,P=0.003).The change rate of the general health score in floating population was higher than the household register population and people stayed temporarily.Conclusion It is necessary to implement the management in whole course to the floating population tuberculosis patients.
