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 evaluate the effect of iron on the stability of fat emulsion in total nutrient admixture (TNA) in pediatrics. Methods Based on intravenous nutrition preparation and handling protocols, 0,0.25, 0.50, 0.75, and 1.00 mg iron sucrose was added in each 100 ml TNA, respectively, and each dose was prepared for 10 bags. The stability of fat emulsion was observed by electron scanning microscopy. The pH and osmolality were determined at different time points (0, 24, 48, and 72 h). Results The fat particle size, percentages of particles ＞ 0.5 μm, pH value, and osmolality were not significantly different among all the groups at different time points (all P ＞ 0.05). The mean particle sizes of the fat emulsion were ＜ 0.5 μm in all groups within 72 h.No fat particle with diameter ＞ 5 μm was seen in each group. Conclusion TNA containing iron sucrose with concentrations range 0.25-1.00 mg per 100 ml is stable.

Background:Medical treatment and surgery are the two main therapeutic approaches for esophageal variceal bleeding ( EVB),but studies showed that the efficacy of medical treatment was poor,and surgery was invasive and could lead to serious complications. Aims:To investigate the efficacy and safety of endoscopic variceal ligation combined with sclerotherapy for treatment of EVB. Methods:A total of 150 cirrhotic patients with EVB admitted from May 2011 to May 2012 at Wenling Oriental Hospital were enrolled and assigned into observation group and control group by random digital table. Patients in observation group were treated with endoscopic variceal ligation combined with sclerotherapy,and patients in control group were treated with somatostatin and pantoprazole. Overall clinical efficacy,recurrence and adverse effect were compared between the two groups. Results:In observation group,the overall clinical efficacy was 94. 7%(72/76), the recurrence rate was 3. 9%(3/76),and the adverse effect rate was 13. 2%(10/76);in control group,the overall clinical efficacy was 79. 7%(59/74),the recurrence rate was 14. 9%(11/74),and the adverse effect rate was 28. 4%(21/74). Overall clinical efficacy in observation group was significantly higher than that in control group(P<0. 05), while recurrence rate and adverse effect rate were significantly lower than those in control group( P all < 0. 05 ). Conclusions:Compared with medical treatment,endoscopic variceal ligation combined with sclerotherapy is effective in improving the clinical efficacy and reducing the recurrence and adverse effect for treatment of EVB. It is worthy of being used in clinical practice.

0.05). However, egg production (0.37?0.22 egg/hen? day) and feed efficiency(0.21 ?0.11 egg kg/feed kg) in group 4(FSD) increased 54.2% and 61.5% respectively. The results from this study showed that egg cholesterol significantly decreased when laying hens were fed fiber-sequestrant.

Objective To assess the clinical outcomes of glutamine supplementation in neonates.Methods The study was designed as a double-blind randomized controlled trial.Totally 100 infants were randomly divided into 5 groups with 20 infants in each group:control group:standard parenteral nutrition (PN);PNI group:PN supplemented with 0.3 g/ (kg·d) glutamine;enteral nutrition (EN) 1 group:EN supplemented with 0.3 g/ (kg·d) glutamine;PN2 group:PN supplemented with 0.3 g/ (kg·d) glutamine;and EN2 group:EN supplemented with 0.3 g/ (kg·d) glutamine,The primary endpoints were the time to establish full enteral nutrition [defined as receiving 120 ml/ (kg·d) enterally],episodes of gastric residuals,total duration of PN,and mortality.The second endpoints were weight gain and head circumference gain,liver function,renal function,days on ventilator,and length of hospitalization.Results Time to achieve full enteral nutrition,incidence of gastric residuals,duration of PN,weight gain (g/d) ,head circumference gain (cm/w),liver function,renal function,and length of hospitalization were not significantly different among all five groups.Days of mechanical ventilation were significantly decreased in PN1 group and PN2 group when compared with the control group (P ＜ 0.05).Intention-totreat analyses showed that,when compared with the control group,PN1 group:RR:1.053;95% CI:0.952-1.164;ENI group:RR:1.333,95% CI:1.035-1.717;PN2 group:RR:1.053,95% CI:0.952-1.164;EN2 group:RR:1.25,95% CI:1.004-1.556.Conclusions Glutamine supplementation may not be able to decrease the time to achieve full enteral nutrition,the incidence of gastric residuals,and the duration of PN.However,pareneral glutamine supplementation does reduce the days on ventilator in neonates.Also,parenteral glutamine supplementation has no obvious influence on mortality.

Objective To analyze clinical characteristics of premenopausal and postmenopausal female patients with kidney stones.Methods The clinical data of 1 194 female adults with kidney stones from December 2004 to December 2014 were analyzed retrospectively.The incidence of kidney stones in different age groups was analyzed firstly.The post-hysterectomy patients or those taking estrogen for breast cancer were excluded, and then 1 166 patients were enrolled.The patients were divided into premenopausal group (464 cases, 39.8％) and postmenopausal group (702 cases, 60.2％), and clinic features of different groups were evaluated.Results The peak age of female patients with kidney stones is between 50 and 59 years old.There were 105 (22.6％) patients in premenopausal group and 204 (29.1％) patients in postmenopausal group complicated with urinary infection.Fifty-eight (12.5％) patients had genitonrinary malformations such as horseshoe kidney, medullary sponge kidney, ectopic kidney, duplex kidney or pyeloplasty for ureteropelvic junction (UPJ) stricture in premenopausal group, as well as 36 (5.1％) in postmenopausal group.Twenty patients (4.3％) had renal insufficiency in premenopausal group, and 66 (9.4％) in postmenopausal group.These differences were statistically significant (P ＜ 0.05).The patients complicated with hydronephrosis (251 vs.346) and ureteral calculi (63 vs.110) of two groups were not significant different (P ＞ 0.05).Multiple factors Logistic analysis indicated that age and urinary infection were statistically significant factors in the occurrence of renal insufficiency (OR =1.037,1.772, P ＜ 0.05).Conclusions The occurrence of genitourinary malformations was higher among premenopausal female patients with kidney stones, while urinary infection and renal insufficiency were more common for postmenopausal patients.Age and urinary infection were the independent factors for the occurrence of renal insufficiency.

Objective To investigate the drug resistant mechanism and homology of three strains of carbapenem-resistant Klebsiella pneumoniae (K.pneumoniae) isolated from different sites of one patient.Methods Three strains of carbapenem-resistant K.pneumoniae were isolated from femoral vein catheter tip,wound secretions and sputum of a patient with severe burns,respectively.Their carbapenemase,metallo-β-lactamase (MBL) and drug resistance genes were detected by modified Hodge test,double-disk synergy test and combination disk diffusion and PCR,respectively,and homology and biological typing were analyzed by enterobacterial repetitive intergenic consensus-PCR (ERIC-PCR) assay and multilocus sequence typing (MLST) technology,respectively.Results The carbapenemase and MBL of three strains of carbapenem-resistant K.pneumoniae were negative and positive,respectively.The blaNDM-1 gene was identified from the three strains,but other drug resistance genes such as blanC,blaGES,blaIMP,blaSPM,blaVIM,blaGIM and blaOXA-48 were not detected.ERIC-PCR showed that three isolates belonged to the same genotype,and MLST showed that they were type ST17.Conclusion Carring blaNDM-1 gene is the main cause leading to the drug resistance of three strains of carbapenem-resistant K.pneumoniae,and they belong to the same genotype.
