ABSTRACT
Objective@#To analyze the detection rate of sleep problems such as sleep delay and deficiency in preschool children in the middle and lower reaches of the Yangtze River in China,and to provide the reference for the standard of sleeping mode among preschool students.@*Methods@#From October to November 2017, a questionnaire survey was conducted among 27 200 preschool children in 11 cities in Hubei, Anhui and Jiangsu provinces in the middle and lower reaches of the Yangtze River in China. Epidemiology of sleep delays, deficiencies and sleep patterns in preschool children was described.@*Results@#The detection rate of sleep problems in preschool children in the middle and lower reaches of the Yangtze River was 15.3%. Taking the length of sleep and bedtime as the main analysis points, it was found that the average sleeping time point of each age group was 21:31, and the detection rate of bedtime delay was 86.5%. The average length of sleep was (10.60±1.12) hours. The detection rate of sleep deprivation in preschool children was 15.7%. Sleep delay was positively correlated with girls, age increase and parents’ higher educational level (P<0.05), and negatively correlated with living in the city, non-only child and bedroom without TV (P<0.01) .The detection rate of sleep deprivation was positively correlated with children of high age group (4yearold group：OR=1.32，95%CI=1.19-1.46；5-year-old group：OR=2.10，95%CI=1.91-2.32；6-year-old group：OR=2.47，95%CI=2.20-2.77)(P<0.01), and negatively correlated with no TV in bedroom (OR=0.91，95%CI=0.84-0.98) and no light in sleep (OR=0.87，95%CI=0.78-0.97)(P<0.05).@*Conclusion@#Preschool children sleep delay and sleep deprivation and other sleep problems are more prominent, affected by family environment and other factors.
ABSTRACT
AIM To observe the therapeutic effects of Safflor Yellow Sodium Chloride Injection and Compound Anisodine Injection on patients with non-proliferative diabetic retinopathy (NPDR).METHODS Sixty-eight pa-tients (102 eyes) were randomly divided into control group (32 cases,48 eyes) and observation group (36 cases,54 eyes).The observation group was given Safflor Yellow Sodium Chloride Injection and Compound Anisodine Injection in addition to conventional therapy administered to the control group,and yet patients of both groups had their changes of vision,fundus hemorrhage,effusion,microaneurysm and central macular thickness checked and compared before and after the treatment.RESULTS The observation group displayed better post-treatment vision recovery,fundus improvement and central macular thickness control than the control group (P ＜ 0.05,P ＜ 0.01).CONCLUSION The combination therapy of Safflor Yellow Sodium Chloride Injection and Compound Anisodine Injection can be an appropriate option for NPDR patients to improve vision and slow progression.
