ObjectiveTo investigate the correlation between sleep patterns and myopia progression among younger school-age children at a primary school in Changning District of Shanghai, based on the data from the Shanghai Students’ Common Diseases and Health Influencing Factors Monitoring System and a sleep-specific survey, so as to provide data support for myopia prevention and control in this age group. MethodsOne primary school was selected from the common diseases and health influencing factors monitoring system for students in Changning District, Shanghai. A total of 230 first-grade students were included in the study. Myopia and refractive parameters were examined, and sleep patterns were investigated. General demographic characteristics and myopia-related behavior data of the students were also collected. Sleep patterns were evaluated in terms of sleep duration, sleep efficiency, and sleep quality, with the latter assessed using the Chinese version of the Children’s Sleep Habits Questionnaire (CSHQ). Multiple linear regression and binary logistic regression models were used to analyze the association between sleep patterns and myopia progression among these students. ResultsThe results of the regression analyses revealed that the total CSHQ score of the students at baseline survey was (48.85±7.15) points. Their sleep efficiency was (94.49±8.48)%, sleep duration was (9.58±0.93) hours, and the proportion of those with insufficient sleep (<10 hours) was 78.26%. At baseline survey, students’ higher daytime sleepiness scores were associated with lower spherical equivalent (SE) ( β=-0.18, 95%CI: -0.31 to -0.04) and an increased risk of axial length (AL) / corneal radius (CR) ratio >3 (OR=1.52, 95%CI: 1.00 to 2.29), whereas longer sleep duration and higher sleep efficiency were associated with higher SE (β=0.18, 95%CI: 0.05 to 0.32; β=0.17, 95%CI: 0.04 to 0.31, respectively), shorter (AL) (β=-0.15, 95%CI: -0.27 to -0.03; β=-0.13, 95%CI: -0.25 to 0, respectively) and a reduced risk of AL /CR>3 (OR=0.70, 95%CI: 0.51 to 0.96; OR=0.73, 95%CI: 0.53 to 0.99, respectively). At baseline survey, children’s higher propensity for sleep problems (OR=1.70, 95%CI: 1.04 to 2.78), sleep resistance (OR=2.26, 95%CI: 1.36 to 3.75), and sleep anxiety scores (OR=2.15, 95%CI: 1.33 to 3.48) were all associated with an increased risk of AL/CR >3 at follow-up (all P<0.05). Furthermore, higher sleep anxiety scores predicted prolonged AL at follow-up (β=0.03, 95%CI: 0 to 0.05). According to the mixed-effects model, higher daytime sleepiness scores and prolonged sleep duration were independently linked to reduced right-eye SE (β=-0.05, 95%CI: -0.10 to 0, P<0.05) and shorter right-eye AL (β=-0.05, 95%CI: -0.10 to 0, P<0.05). ConclusionIn this school in Shanghai, there are problems of insufficient and poor-quality sleep among young children. Sleep problems such as sleep resistance, delayed sleep onset, sleep anxiety, and daytime sleepiness among children may accelerate the risk of myopia progression, while longer sleep duration and higher sleep efficiency may serve as protective factors against the occurrence and development of myopia.

Objective To investigate the drug resistance and risk factors of hospital-acquired pneumonia (HAP) induced by imipenem-resistant Acinetobacter baumannii.Methods Clinical data on 114 patients with Acinetobacter baumannii-related HAPs admitted in Wujiang First People' s Hospital in Suzhou during January 2013 and December 2014 were retrospectively analyzed.According to the results of drug sensitivity test,patients were divided into imipenem-resistant group and non imipenem-resistant group.Drug resistance to 20 commonly used antibiotics was observed in two groups,and multivariate Logistic regression analysis was performed to identify the risk factors of imipenem-resistant Acinetobacter baumannii infection.Results Among 114 strains ofAcinetobacter baumannii,66 strains (57.89%) were imipenem-resistant and 48 strains (42.11%) were non-imipenem-resistant.The resistance rates to β-lactams,quinolones and aminoglycosides were significantly higher in imipenem-resistant group than those in non-imipenem-resistant group (P < 0.01),and no tigecycline-resistant strain was found in both groups.Univariate analysis showed that acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score ≥ 15,plasma level of albumin ≤ 25 g/L,intensive care unit (ICU) stay,indwelling gastric tube,deep venous catheterization,establishment of artificial airway,mechanical ventilation time ≥ 7 d,use of broad-spectrum antibiotics ≥ 14 d and combined use of antibiotics were risk factors of imipenem-resistant Acinetobacter baumannii related HAP (x2 =13.06,6.86,25.40,15.09,17.87,21.46,17.94,6.91 and 10.10,P <0.01).Multivariate Logistic regression analysis revealed that establishment of artificial airway [OR =72.014,95% confidetial interval (CI):19.566-265.061,P < 0.01],and use of broad-spectrum antibiotics ≥ 14 d (OR =3.892,95% CI:1.092-13.879,P < 0.05) were independent risk factors of imipenem-resistant Acinetobacter baumannii related HAP.Conclusion Imipenem-resistant Acinetobacter baumannii strains are highly resistant to most antibiotics.Strict control of invasive procedures and long-term combined use of antibiotics may reduce the occurrence of imipenem-resistant Acinetobacter baumannii related HAPs.

Objective To increase acupuncture doctors' compliance on hand-washing, with which cross-infection can be avoided and the security level of acupuncture can be raised. Methods To get the information on current situation of hand-washing by direct observation. Aiming at present issues, we adopted such measures as improving hand-cleaning facilities and intensifying training of hand health knowledge and hand health manipulations to prevent them. Such methods as self reporting, indirect measuring, inquiring patients, and tracking surveys were used to evaluate the effects. Results Executive rate of hand-cleaning was 14% and 79% before and after the measures' intervention respectively. Conclusion As needles are inserted into the skin for the treatment, these needles may contaminate the blood or tissue fluid of the patient. The insanitation of hand may increase this contagious risk. Therefore, we must guide the acupuncturists to pay attention to their hands sanitation.
