    Objective To identify major factors of child obesity in preschool children for providing target factors for intervention. Methods Parents of preschool children,kindergarten teachers and kindergarten principals were chosen through convenience sampling for focus group interview or deep personal interview.Questionnaires were distributed to a total of 400 parents of 2 to 7 year-old children from five kindergartens in Beijing urban and rural areas.Information of qualitative interviews was obtained and summarized with keyword extraction.Overweight or obesity was determined by reference norm for screening obesity in Chinese preschool children [body mass index(BMI)≥the 85th percentile was defined as overweight or obesity].Multivariate Logistic regression analysis was used to identify potential correlates. Results Overweight and obesity rates were 16.5% and 28.0%,respectively.Multivariate Logistic regression analysis found:1) risk factors:high birth weight (≥4 000 g)(OR=31.55;95%CI:1.78~4.17,P<0.001),caesarean birth (OR=4.89;95%CI:1.42~16.89,P=0.01),breastfeeding and formula feeding (OR=25.90;95%CI:3.07~218.39,P<0.001)and rare breastfeeding (OR=11.15;95%CI:1.686~73.7121,P=0.01),compared with exclusive breastfeeding;2) Protective factors:fathers'higher education(OR=0.32;95%CI:0.12~0.89,P=0.03),eating coarse grain frequently (OR=0.43;95%CI:0.21~0,87,P=0.02),and eating at home frequently (OR=0.86;95%CI:0.75~0.98,P=0.02). Conclusions Perinatal factors,family environment,birth and feeding conditions and children's diet and exercise behaviors are correlations of child obesity.With increasingly high incidence of overweight and obesity among Chinese preschool children,early intervention measures should be taken for reducing the incidence and development of overweight and obesity among preschool children.

    Objective To assess the vitamin A status in the primary and secondary school students in Qiongzhong county,Hainan,China,and to provide bases for the prevention of adolescents' vitamin A deficiency. Methods Students were sampled using stratified cluster sampling methods.Two primary schools and two secondary schools were randomly selected and then one class was chosen from each grade.Serum retinol concentrations were measured using a high performance liquid chromatography method. Results A total of 561 students were investigated,the mean serum retinol concentration was (360.36±91.39)ng/mL,and no significant difference between the boys and the girls was found(P>0.05),yet the serum retinol concentration got higher as the age growing(P<0.05).Only 2.0% of investigated students had vitamin A deficiency (serum retinol ≤200 ng/mL),but 22.3% of them had vitamin A marginal deficiency (200~300 ng/mL),and both of them were not different in genders(P>0.05),yet the vitamin A marginal deficiency rate decreased with the age increasing (P<0.05). Conclusions Primary and secondary school students in Qiongzhong county have a relatively low vitamin A deficiency rate,yet a remarkably high rate of vitamin A marginal deficiency,surveillance should be done continuously as well as prevention and control measures,especially among students aged 6 to 7 years old.

    Objective To understand the control and treatment of children with bronchial asthma in the Affiliated Hospital of Ningxia Medical University of the Ningxia Hui Autonomous Region. Methods The study was achieved by means of collecting the face-to-face questionnaires among researchers,outpatient children of 2~16 years old and their guardians from January,2013 to March,2014. Results There were 149 asthmatic children,including 109 male cases and 40 female cases.The sex ratio was 2.7∶1,among them the preschool and school-age children accounted for 31% and 45% respectively.From the statistics of past 12 months,27 cases had been fully controlled,94 cases were in partial control and 28 cases with no control,among them 129 cases were routine follow-up visitors.Cough and wheeze were the main symptoms of asthma which respectively account for 94.63% and 71.14%;73 cases (49%) had been attacked in the past three months and 52 cases (34.9%) happened in nearly one month,17 cases were complicated by nocturnal symptoms (11.4%) and 64 cases with allergic rhinitis.There were 132 cases (88.6%) suffering the inhaled corticosteroid treatment and 55 cases (36.91%) had been treated with antibiotics;in the past one year,the emergency treatment rate and hospitalized treatment rate due to the acute asthmatic attack respectively accounted for 16.1% and 30.2%.About 2/3 of children took greater amount of exercise than before in the recent one year,which was even same to the same age children. Conclusions There still exists a certain disparity between the realistic effect and the ideal goal of the asthmatic treatment in our hospital.Proactively promoting the propaganda and education of asthma as well as necessity of the drug use in remission,strengthening the nursing,taking proper exercise and avoiding infecting and contacting allergens are helpful to improve the asthma control.

    Objective To discuss the correlation of fractional exhaled nitric oxide (FeNO) and peripheral blood eosinophil (EOS) in children with asthma,and to investigate the clinical significance of FeNO and EOS in asthmatic children,and to provide the basis for early diagnosis and effective treatment. Methods A total of 45 cases of children with asthma were collected from July 2012 to December 2013 in the pediatric ward and clinic of the Linqu County People's Hospital,26 cases of normal control group.FeNO and EOS were measured respectively. Results 1) The levels of FeNO and EOS in acute asthma group[(57.34±41.53) ppb],[(1.66±4.52)×109/L]were significantly higher than those in remission group[(41.48±26.96) ppb),[(0.63±0.56)×109/L]and control group[(16.14±6.37) ppb],[(0.08±0.07)×109/L],the differences were statistically significant (P<0.05).2)The levels of FeNO and EOS in remission asthma group were still higher than those of the control group,the differences were statistically significant (P<0.05).3)The level of FeNO in asthma group was positively correlated with the level of peripheral blood EOS (r=0.71,P<0.05). Conclusions Increased FeNO levels in children with asthma had a good correlation with EOS,which can indirectly reflect the level of airway eosinophilic inflammation,and the sensitivity is higher than EOS.The remission of asthma airway inflammation is still need to be anti-inflammatory treatment.The combined use of FeNO and EOS can assess the severity and adjust the treatment plan in clinic.

    Objective To analyze the clinical and electroencephalogram (EEG) characteristics of Angelman syndrome (AS) diagnosed in infancy and provide clues for early diagnosis. Methods The clinical and video-electroencephalogram (VEEG) data of 5 patients with AS confirmed by genetic diagnosis were analyzed and the literature review was carried on. Results Among the 5 patients aged 6~12 months,four were male and one was female.The main symptom was motor and mental retardation in all the patients.Four cases were misdiagnosed as cerebral palsy in other hospitals.Two patients had frequent laughter,and one showed abnormal sleep-wake cycles.No patient presented seizures.Four cases showed microcephaly,and 2 had flat occiput.Two had hypopigmented skin light hair and one had wide mouth.Gesell tests presented moderate to severe development delay (70%) and speech ability showed affected seriously.The VEEG of all the patients showed general high-amplitude slow waves during awake and sleep times paroxysmal or continuously.The slow waves might migrate between the different sites,spike or sharp waves might be mixed within this pattern. Conclusions The clinical symptoms of AS in infancy are usually atypical,and the main characteristic is development delay.VEEG is a very sensitive and specific method to make early diagnosis for AS.
