Obesity is a common cause of nonalcoholic fatty liver disease(NAFLD).Recently,the morbidity of NAFLD has increased rapidly worldwide,associated with obesity prevalence.NAFLD,metabolic syndrome(MS)and insulin resistance are closely related.The increase in weight,especially in visceral fat tissue,was the highest risk factor to cause NAFLD and MS,and for their progress.To NAFLD patients,the only effective measure is weight reduction,including reasonable diet and aerobic exercise.Moreover,a sound mentality and behavior are the key factors of the treatment of NAFLD.On the other hand,the literature lacks well-designed,randomized control trials that assess the efficacy of anti-obesity drug and weight-loss surgery on the long-term outcomes of NAFLD.

Extrauterine growth restriction (EUGR) in premature infant is a common problem in the world. The reasons for high EUGR rate, such as declining gestational age and birth weight, getting more medical treatment and examination or interruption of nutritional support, had been profoundly studied. However, there are few reports about the limited ability of intakes of energy and various nutrients and the updating of the growth standard curve . Research suggested that the average time taken to reach the recommended fat intake in preterm infants is proximately day 6 after birth, protein day 4 after birth, carbohydrate one-week after birth. Vitamins and trace elements are usually not able to or take a long time to reach the recommended nutrient intake. Without enough intake of energy and nutrients to maintain the need of intrauterine growth rate and catch-up growth in preterm infants, EUGR cannot be improved. In this paper, the EUGR and the intake of important nutrients, such as energy, fat, protein, vitamins and minerals, etc., during hospitalization were reviewed in hope to achieve more rational and standardized management for preterm infant,and provide more reasonable advise to control EUGR.

More studies have shown that dietary calcium intake can decrease the incidence of metabolic syndrome. Milk consumption in childhood and the habit of milk drinking are positively correlated with bone mineral density in adult-hood. This article summarizes the relationship between dietary calcium and bone mineral density and obesity-related metabolic disorder in children.

Objective To investigate the effect of nutritional therapy for an infant with short bowel syndrome (SBS) who had jejuno-colostomy. Methods An individualized nutritional support before and after the closure of jejunum colostomy was provided to a 3-month-old girl with SBS who had jejuno-colostomy so as to find out its influence on prognosis. Results Paren-teral nutrition is a life-saving therapy for infants with SBS. The proper enteral nutrition can improve intestinal tolerance and re-duce the incidence of postoperative complications, and improve outcomes of SBS infants. Conclusions Appropriate nutrition therapy is important to reduce the complications and improve the prognosis of SBS infants.

Anemia is one of the most common disease in premature infants,it not only affects growth and development,but also have long-term impact on the future movement,cognition,learning ability and behavioral development,and most of mental harms nor reversible even though after iron supplementation.So,supplementation with intravenous iron will be a good approach to prevent and treatment with anemia for oral iron supplementations invalid or intolerant infants.Currently,safety and start time for iron supplementation in preterm infants remains controversial.This review focuses on the efficacy and safety of intravenous iron for prevent and treatment of iron deficiency anemia in preterm infants.

Objective To investigate the association between activity energy expenditure ( AEE ) and body composition in school-age children.Methods A total of 62 students ( Grades 3 and 4, aged 8 -10 years) from a primary school in Shanghai were enrolled in this study .AEE was estimated with a metabolic cart (energy metabolism determination system ).Body composition (body mass, body mass index, fat percentage, fat mass, fat-free mass, fat mass index, fat-free mass index, obesity degree) was evaluated by bioelectrical im-pedance analysis .The above indicators were compared between obese and non-obese students .Results There were no statistically significant differences in exercise time , total AEE and relative AEE between obese and non-obese boys [ (9.70 ±1.91) min vs.(10.00 ±1.97) min, t=0.336, P=0.739; (198.74 ±53.33) kJ vs.(171.54 ±41.75) kJ, t =-1.422, P =0.165; (0.46 ±0.09) kJ/(min· kg) vs.(0.51 ± 0.04) kJ/(min· kg), t=2.043, P=0.051], while obese boys had higher absolute AEE than non-obese boys [(20.06 ±3.14) kJ/min vs.(16.93 ±1.85) kJ/min, t=-2.910, P=0.007].Obese girls had shor-ter exercise time and lower relative AEE than non-obese girls [ (7.35 ±3.05) min vs.(9.98 ±1.82) min, t=2.509, P=0.027;(0.41 ±0.09) kJ/(min· kg) vs.(0.51 ±0.07) kJ/(min· kg), t=3.244, P=0.003 ] , whereas there were no statistically significant differences in total AEE and absolute AEE between obese and non-obese girls [ (129.29 ±71.13) kJ vs.(161.50 ±35.38) kJ, t =1.351, P =0.203; (16.82 ± 3.26) kJ/min vs.(16.17 ±2.00) kJ/min, t=-0.676, P=0.504].After controlling for age and gender, absolute AEE was significantly positively correlated with body mass index ( P=0.015 ) , obesity degree ( P=0.010), fat mass (P=0.047), fat-free mass (P=0.010), and fat-free mass index (P=0.003) in boys, but not in girls.Relative AEE was significantly negatively correlated with body mass index ( boys: P =0.000, girls: P=0.000), obesity degree (boys: P=0.002, girls: P=0.000), fat percentage (boys:P=0.000, girls:P=0.001), fat mass (boys:P=0.000, girls:P=0.000), fat-free mass (boys: P=0.002 , girls: P=0.022 ) , and fat mass index ( boys: P=0.000 , girls: P =0.000 ) in both boys and girls.Conclusions In obese children, AEE is correlated with body composition, with relative AEE reducing as obesity degree increasing.There may be complex relationships among body size , body composition, and energy metabolism in children.

Objective To assess the enteral iron and energy intake of premature neonates during hospitalization in neonatal intensive care unit(NICU).Methods This retrospective study enrolled 208 premature neonates admitted in the NICU of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine within 48 hours after birth from January 2012 to December 2013.The following data were recorded for all infants:clinical basic information,the amount of formula iron intake in milk,enteral and parenteral nutrition intake as well as oral iron supplementation.Results The amount of enteral iron intake in the 1st,2nd,3rd,4th week after birth and at discharge was (0.2 ± 0.3) mg/(kg · d),(0.9 ±0.7) mg/(kg · d),(1.2 ±1.0) mg/(kg · d),(1.5 ± 1.1) mg/(kg · d),and (2.2 ± 1.1) mg/(kg · d),respectively,which accounted for 10％,45 ％,60％,75 ％ and 110％ of the recommended iron intake.The energy intake in the 1st,2nd,3rd,4th week after birth and at discharge was (13.2 ± 14.8) kcal/(kg · d) (1 kcal =4.184 kJ),(46.0 ± 32.6) kcal/(kg · d),(62.2 ± 38.1) kcal/(kg · d),(71.3 ± 38.2) kca]/(kg · d) and (105.3 ± 32.1) kcal/(kg · d),which accounted for 11.0％,38.3％,51.8％,59.4％ and 87.8％ of the recommended intake,respectively.Lower enteral iron and energy intake after birth occurred in the premature infants with lower birth weight,especially those with anemia who had significantly lower enteral iron intake than the normal neonates in the first 2 weeks after birth.Conclusions Enteral iron and energy intake among premature neonates were insufficient,especially during the first 2 weeks after birth.It is necessary to develop and implement more effective nutritional support to improve the nutritional status of premature infants.

Objective To investigate urinary iodine and dietary iodine intake in adults, and to ana-lyze the relationship of urinary iodine and daily dietary iodine intakes with thyroid nodules.Methods To-tally 30 participants with nutritional background were enrolled prospectively from January to March 2015 in Shanghai.The 3-day survey of 24-hour's diet record was made using weighting method to evaluate the daily nutrient intakes.On the second and third days of dietary records, urine samples in fasting status and 2 hours after meals were collected from all the participants (n=240).The levels of urine iodine were meas-ured, and dietary iodine intake calculated.3-month food frequency questionnaire was completed and thy-roid ultrasonography performed.Results The median urinary iodine ( MUI) of fasting and 2 h postprandi-al urine samples was 137.56 μg/L ( 91.4-211.5 μg/L) .The portions of participants with iodine insuf-ficiency, iodine adequate, and iodine above requirements or excess were 20.2%, 56.7%, and 23.3%, respectively.Inter-individual MUI varied from 36.31 μg/L to 359.20 μg/L.No significant difference was found between the fasting urinary iodine and 2 h postprandial urinary iodine ( P=0.389 ) .The average di-etary iodine intake was (197.2 ±74.2) μg/d, and the proportions from iodine salt and drinking water were 70.2% and 5.4%, respectively.There was a significant positive correlation between dietary iodine intake and urinary iodine value of the same day (r=0.426, P=0.019).Participants with thyroid nod-ules had higher urinary iodine than participants without thyroid nodules [ ( 194.0 ±101.5 ) μg/L vs. (135.7 ±72.9) μg/L, P<0.001].Conclusions Inter-individual iodine nutritional status are signifi-cantly different under natural living status.Increased urinary iodine may be related with thyroid nodules. Repeat random urine iodine test combined dietary assessment may reduce the error in evaluating individual iodine nutritional status.

Objective To study the plasma antioxidant vitamin status in patients receiving enteral nutrition(EN) or parenteral nutrition(PN) after upper gastrointestinal surgery.Methods One hundred and twenty patients who underwent upper gastrointestinal cancer surgery were randomized into EN and PN group.The plasma vitamin A,vitamin E and ?-carotene levels pre-and post-operation and one week after clinical nutrition supplement were studied.Results Vitamin A and ?-carotene levels decreased significantly after surgery(P=0.03 and P=0.01,respectively).Vitamin E decreased 10 weeks after the nutrition,and it was significantly lower in the EN group than in the PN group(P0.05).Conclusions A decrease of antioxidant vitamins is induced by surgery and vitamin E is recommended to be given in nutrition supplement patients,especially in the patients receiving EN.
