AIM: To analyze the amblyopia morbidity status of young children in Shaanxi city of Xi'an Province, and to explore the related risk factors. ·METHODS: Totally 10268 children between 3-6 years old were screened in 8 kindergartens in our city from March 2012 to April 2016 via a simple non-repeated sampling method, and sight, eye position, eye movement examination were mainly implemented;10g/L atropine mydriatic optometry was taken to detect eye fundus examination, and to eliminate organic lesion. There were 528 amblyopic children were set as the observation group, 500 healthy children who were treated in our hospital at the same time were set as the control group. Single factor analysis and multiple logistic regression analysis were carried out for children with amblyopia. ·RESULTS:In a survey, the incidence rate of amblyopia among young children in Shaanxi Xi'an was 5. 14%. Ametropic amblyopia accounted for the highest proportion (61. 4%), and lesion extent was usually mild to moderate, ametropic amblyopia accounted for 24. 1%, which was inferior to that was the strabismus accounted as 12. 9%, rare were form deprivation amblyopia accounted for 1. 7%. General data analysis showed that, there were significant differences between the two groups in maternal gestational age, gestational weeks and times of pregnancy, smoking history of parents, family genetic history of myopia (P<0. 05). Multivariate logistic regression analysis showed that pregnancy when old, mother's smoking history, family genetic history of myopia and short gestational weeks were risk factors for amblyopia in young children (P<0. 05). · CONCLUSION: There is a certain oneset risk of amblyopia in young children in Shaanxi Xi'an. Attention should be paid to educate eye care knowledge, organize regular visual screening, ensure early detection, early diagnosis, early treatment.

Objective To investigate the hypothesis that food allergy in infants may be associated with variation in their intestinal microflora. The formation of intestinal microflora in healthy infants and changes in food allergic infants were detected.Methods 16S rRNA gene sequences specific for bifidobacterium, lactobacillus and escherichia coli in fecal were quantitatively detected by real-time PCR. The three fecal floras were assessed in 71 healthy infants and 100 infants with food allergy. Results After birth,there were bifidobacteria colonized in infantile intestine,then the number increased rapidly up to 5 times at the sixth month, which was always the preponderant flora. Lactobacilli was also presented in infantile intestine 1 month after birth and augment gradually. The number of Escherichia coli was less than bifidobacteria and lactobacilli and appeared to decline during the early infants. The number of bifidobacteria and lactobacilli in the infants with food allergy were markedly less than that in the healthy infants, but escherichia coli was significantly more than that in the healthy infants.Conclusions During the first year of life,the intestinal microflora in infants is in a developing process. Compared with the healthy infants,bifidobacteria and lactobacilli decrease, but escherichia coli increase in the food allergic infants.These results indicate that the probiotics may be benefit to the prevention and treatment of food allergy.
