Objective To explore the expressions and significance of miRNA - 101,enhancer of ZESTE homo-log 2(EZH2)and transforming growth factor(TGF)- β1 in the kidneys with complete uniateral ureteral obstruction (CUUO). Methods Thirty male SD rats,(6 ± 1)weeks old,weighted(150 ± 10)g,were divided into sham group, 7 - day group with CUUO and 14 - day group with CUUO by using random number table method,10 rats in each group. The obstructed kidney samples were collected in 7 and 14 days,respectively,for detecting the expression of miRNA -101 by real time - polymerase chain reaction(RT - PCR)and TGF - β1 and EZH2 protein by Western blot,immuno-histochemistry and hematoxylin - eosin staining. Their correlated expressions were analyzed. Results RT - PCR results showed that the expressions of miRNA - 101 in sham group and 7 - day group with CUUO were(12. 69 ± 1. 60)times and(3. 74 ± 1. 24)times which were higher than those of 14 - day group with CUUO,respectively,there was a signifi-cant difference among these 3 groups(P ﹤ 0. 05). The expressions of TGF - β1 and EZH2 proteins were 1. 14 ± 0. 12, 1. 04 ± 0. 14,0. 76 ± 0. 18 and 1. 04 ± 0. 04,0. 89 ± 0. 03,0. 73 ± 0. 02 in 14 - day group with CUUO,7 - day group with CUUO and sham group,respectively. There was a negative correlation between miRNA - 101 with EZH2( r =- 0. 92,P ﹤ 0. 05),and negative correlation with TGF - β1(r = - 0. 63,P ﹤ 0. 05),and positive correlation between EZH2 and TGF - β1(r = 0. 67,P ﹤ 0. 05);the expressions of miRNA - 101,EZH2 and TGF - β1 were associated with each other in obstruction renal in different time periods. Conclusions With the extension of obstruction time, miRNA - 101 expression decreased,EZH2 and TGF - β1 expression increased,evidently,which indicates that the de-velopment of renal interstitial fibrosis may be affected through regulating EZH2 expression of renal obstruction through miRNA - 101 in the young rats.

Objective To investigate the effect of erythropoietin(EPO)on the expression of aquaporin - 2 (AQP2)in the kidney of young SD rats after release of bilateral ureter obstruction(BUO - R). Methods Thirty - two young SD rats were equally divided into 4 groups randomly(BUO group,BUO - R group,BUO - R ﹢ EPO group and Sham group,8 rats in each group). The BUO model was built through bilateral ureteral ligation. EPO(500 U/ kg)was given to BUO - R ﹢ EPO rats at 2 h after release of BUO,and then repeated 6 h,12 h,24 h and 36 h thereafter and the same volume of 9 g/ L saline was simultaneously given to BUO - R rats. The Sham group was prepared in parallel by laparotomy and free dissection of bilateral ureters but not ligated. Both side kidneys were harvested 48 h(72 h for Sham group)after release of BUO to examine the effect of EPO on the expression of AQP2 in inner medulla by immunohisto-chemistry,Real - time PCR and Western blot. The urine samples were collected by using metabolic cage before death. Results The osmotic pressure of BUO - R ﹢ EPO group was higher than that of BUO - R group,but lower than that of Sham group(P ﹤ 0. 05). Immunohistochemistry showed that the collecting duct wall thinned and lumen enlarged. After the pictures were analysized by using Image - Pro Plus software,it showed that the expression of AQP2 in collecting duct in BUO group was significantly down - regulated compared with that in Sham group,whereas,it was slightly weaker in BUO - R group and BUO - R ﹢ EPO group than Sham group(P ﹤ 0. 05). These results were further confirmed by a-dopting Western blot,and the relative quantity of AQP2 in BUO group was also the lowest of the four groups(P ﹤0. 05). Real - time PCR showed that the level of AQP2 mRNA in Sham group was(24. 30 ± 1. 03)folds of BUO group,(10. 60 ± 1. 05)folds of BUO - R group and(5. 70 ± 1. 01)folds of BUO - R ﹢ EPO group,respectively. Conclusion EPO could promote not only the recovery of AQP2 mRNA and protein expression but also the recovery of AQP2 function in young BUO - R rats.

Objective:
To describe the linear growth trajectory and BMI growth trajectory of children aged 0-6 years, and to investigate the relationship between different growth trajectory patterns and refractive error of preschool children.
Methods:
The participants were selected from Ma anshan Birth Cohort Study (MABC), which was established from May 2013 to September 2014. In this study, 15 follow up interviews were conducted among 2 037 live births between 42 days after birth and 72 months of age to collect the data of body length and body weight. And at the age of (72±6) months, data of the naked eye visual acuity was measured by professional ophthalmologist in Ma anshan Maternal and Child Health Hospital. The latent class growth model was conducted to identify distinct linear growth trajectory and BMI Z score trajectories of 0 to 6 year old infants and young children. Multinomial Logistic regression model was used for analyzing the relationship between distinct growth trajectories and ametropia in 6-year-old children.
Results:
According to the latent class growth model, children showed three obvious linear growth trajectories: slow growth trajectory ( n =302), normal growth trajectory ( n =1 162), and fast growth trajectory ( n =573). And BMI growth trajectory were also divided into three patterns: slow growth trajectory ( n =630), normal growth trajectory ( n =1 058), and fast growth trajectory ( n =349). Multinomial Logistic regression analysis showed that linear slow growth trajectory was a risk factor for hyperopia in 6-year-old children ( OR =1.80, 95% CI =1.09-2.98, P <0.05). But it was not significantly associated with myopia. There was no significant correlation between fast growth BMI pattern and slow growth BMI pattern with myopia and hyperopia in 6-year-old children.
Conclusion
Slower growth patterns in linear growth trajectories were associated with hyperopia in 6-year-old children.It should pay close attention to the height growth pattern of preschool children. Regular examination of physical development indicators and distance vision can help prevent the occurrence and development of ametropia in preschool children.

Chinese Journal of School Health 2019;40(8):1173-1176
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.
