Extremely low birth weight infants(ELBWI)are the greatest risk infants in NICU.Nutrition management influence directly surviving and prognosis of these infants in addition to the essential life support technology.Nutrition requirement,enteral and parenteral nutrition,feeding after discharge for ELBWI is introduced in this article.The ideal goals of nutrition support for ELBWI is to achieve growth similar to foetal growth coupled with satisfactory functional development and composition of weight gain for a normal fetus.

The Apgar score, as a convenient and practical method for clinical screening in newborns during the first minutes of life, has been widely used for more than six decades. However, with the advent of modern medical technology, the continued use of Apgar score has been a matter of controversy due to its limitations, including that it is prone to be influenced by many factors. We provide a new insight into the Apgar score, based on the updated clinical evidence, its relationship with neonatal resuscitation, and its predictive value in neonatal outcome.

Objective To summarise the clinical data of neonatal early onset sepsis (EOS) and investigate the correlation factors, clinical manifestation, diagnosis, therapy and prognosis of EOS. Methods Data of 32 neonatal EOS patients admitted into the neonatal intensive care unit, Peking Union Medical College Hospital from January 2000 to June 2009 were collected and retrospectively analyzed. Results Among 32 EOS infants, there were 23 preterm infants (71.9%), nine term infants (28.1%); 21 low birth weight infants (65.6%), six very low birth weight infants (18.8%) and one macrosomia (3.1%). Among 32 mothers, 27 (84.4%) were accompanied with various kinds of complications during perinatal period, such as 15 perinatal infection (46.9%), six preeclampsia (18.8%), five gestational diabetes mellitus (15.6%) and one hypothyroidism (3.1%). EOS infants had various clinical manifestations, including 25 low response (78.1%), 20 respiration or temperature abnormity (62.5%), 18 pallor and clammy skin (56.3%), 18 feeding intolerance (56.3%), 18 fever (56.3%), 15 metabolic acidosis (46.9%), 8 infectious shock (25.0%), 20(62.5%) high white blood cell count (>25×109/L), 22 (68.8%) low blood platelets (<100×109/L) and 28 (87.5%) high C-reaction protein (>8 mg/L). Blood culture of 24 infants were positive (75.0%), among which nine infections were caused by gram-positive bacteria (9/24, 37.5%), including Listeria monocytogenes, group B Streptococcus, Staphylococcus, et al; 15 infections were caused by gram-negative bacteria (15/24, 62.5%), including Klebsiella Pneumoniae, Enterobacteria, Bacillus Smaragdinus, et al. Antibiotics were used in all infants when EOS was supposed to be or infectious symptoms were presented, and were adjusted under the results of culture. Twenty-two infants (68.8%) were cured, eight(25.0%) were given up from the therapy, two(6.3%) died. Conclusions The neonatal EOS correlates to various kinds of perinatal factors, its clinical manifestations are complicated and usually involves many systems. Multiple factors in perinatal period, clinical manifestation and laboratory examinations should be considered to make early diagnosis, assist management to improve the prognosis.

Objective To compare the diagnostic values of different parameters for neonatal sepsis by observing clinical presentations and laboratory tests of hospitalized newborn infants and to find out the the early and fast way in neonatal sepsis diagnosis. Methods Newborn infants admitted to NICU from Sept.2007 to Feb.2008,who met all inclusion and exclusion criteria,were enrolled.The situations in perinatal period,exact time of the onset of infection,clinical manifestations and laboratory indexes were recorded.Infants were classified into 3 groups:septic group(n=13),nonseptic group(n=12) and noninfectious group(n=12).Sensitivity,specificity,false positive rate,false negative rate,Youden's index and positive and negative predictive values(PPV and NPV) were calculated for each test. Receiver-operating characteristic curves were analyzed to determine the optimal thresholds. Results Among all the clinical manifestations,abnormal reaction had the hightest specificity(84.6%) and accuracy(67.9%) in diagnosing neonatal sepsis.SIRS criteria,with the specificity of 95.8%,was helpful in clinical suspected eases.However,routine laboratory tests,such as WBC,PLT and GLU,had poor sensitivity or specificity;I/T had better specificity(100%),but was subject to discrepancy among different observers.The area under the ROC for CRP and PCT were 0.734 and 0.878,with the optimal threshold of 15 mg/L(P=0.020,Youden's index=45.5%) and 0.81 ng/ml(P-0.000,specificity=100%,Youden's index=75.0%),respectively.Conclusions Careful clinical inspection warrants early detection of sick infants.Evaluation of SIRS criteria in clinical suspected septic infants may help in early diagnosis.WBC,I/T,PLT can be used as routinely monitoring indexes for high risk neonates.CRP and PCT concentrations also have significant diagnostic values.

Objective To explore the effect of fortified human milk feeding on growth,metabolism and complications of premature infants during hospital stay.Methods Totally,148 premature infants of gestational age ≤36 weeks and birth weight ≤1800 g,admitted to NICU of Peking Union Medical College Hospital between January 1st,2009 and December 31st,2012,were retrospectively enrolled and divided into two groups.Infants fed predominantly (＞50％) with human breast milk,combined with human milk fortification (HMF) formula when breast milk was insufficient during hospital stay,were named HMF group (n =73),and those fed exclusively with premature formula were called premature formula feeding group (PF group,n =75).Data of infants on growth,metabolism and incidence of various complications were compared between the two groups.Clinical data were expressed with mean± standard deviation or median and quartiles [M(P25,P75)].Statistical analysis was performed with t-test,x2 test or non-parameter test.Results Among the 148 infants included,there was no significant difference in gestational age,birth weight,head circumference,length at birth,time for regaining birth weight,SGA at birth,neonatal respiratory distress symdrome,intraventricular hemorrhage (over grade Ⅲ) and asphyxia rate between HMF and PF group(all P＞0.05).Infants of the HMF group showed shorter duration of parenteral nutrition [18 d(14 d,25 d) vs 24 d (18 d,31 d),Z=-2.950,P=0.003],smaller age to achieve 120 ml/(kg · d) through enteral feeding [16 d(12 d,23 d) vs 22 d (16 d,30 d),Z=-2.895,P=0.004],smaller age to achieve total energy intake of 120 kcal/(kg · d) [11 d(8 d,15 d) vs 14 d (10 d,18 d),Z=-2.392,P=0.017] than those of the PF group.Medical cost during hospital stay in the HMF group was significantly less than in the PF group [RMB:47 078 yuan(30 802 yuan,67 039 yuan) vs 58 400 yuan (38 166 yuan,82 737 yuan),Z=-1.970,P=0.049].The time for initial feeding,rate of feeding intolerance,daily weight gain after regaining birth weight,weekly increase of body length and head circumference,weight,body length and head circumference at discharge,proportion of small for gestational age infants at discharge,z scores of both birth weight and weight at discharge showed no significant difference (all P＞ 0.05).The level of blood alkaline phosphates before discharge in HMF group was significantly higher than that of the PF group [(347.7±149.4) U/L vs (288.6±108.8) U/L,t=2.570,P=0.011].None of the other biochemical indicator showed any statistical difference.The incidence of sepsis in the HMF group was slightly lower than that in the PF group [11.0％ (8/73) vs 20.0％ (15/75)] without significant difference (x2 =2.30,P＞ 0.05),neither the morbidity of retinopathy of premature,chronic lung disease,necrotizing enterocditis of newborns (all P＞0.05).Conclusions HMF for premature infants may ensure the same growth pattern as those fed by premature formula,and it also can accelerate the enteral feeding process,reduce the incidence of sepsis and decrease the medical cost during hospital stay.

Objective To summarize and analyze the impact factors on enteral feeding in very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI). Methods A retrospective study was carried out in VLBWI and ELBWI who had achieved full enteral feeding prior to discharge. The impact factors correlated to the time of achieving full enteral feeding were analyzed. If the data underwent bi-variable normal distribution, they were analyzed with Pearson correlation test; otherwise they would be analyzed with Spearman correlation test. T test was used for single factor analysis and multiple linear regression analysis was carried out to determine the significant risk factors associated with the time of achieving full enteral feeding. Results One hundred and forty-seven infants with mean gestational age of (31.0±2.0) weeks, mean birth weight of (1246±185) g and mean time of achieving full enteral feeding of (24. 4± 10. 5) days were admitted. With the single factor analysis, it was found that birth weight (r=- 0. 477, P = 0. 000), gestational age (r = - 0. 405, P= 0. 000), mechanical ventilation duration (r= 0. 393, P = 0. 000), the time began to enteral feeding (r = 0. 318, P = 0. 000), initial milk volume (r = - 0. 263, P = 0. 001 ), the milk volume on the third day (r= -0. 412, P=0. 000) and the seventh day (r= -0. 592, P=0. 000),neonatal respiratory distress syndrome (t = 3. 368, P = 0. 001), umbilical catheterization (t = 3. 571,P=0. 000), abnormal blood glucose level (t=3. 285, P=0. 001), aminophylline using (t=4. 341,P=0. 000), phototherapy (t=3. 054, P=0. 003) and sepsis (t=3. 244, P=0. 001) were correlated to the time of achieving full enteral feeding. Multiple linear regression showed that the birth weight (t=4. 175, P= 0. 000), the time began to enteral feeding (t= 2. 851, P = 0. 005), aminophylline using (t=2. 231, P=0. 027), sepsis (t=3. 895, P=0. 000), phototherapy (t=2. 852, P=0. 005)and the milk volume on the seventh day (t= 7. 332, P=0. 000) were significantly correlated with the time of achieving full enteral feeding. Conclusions The enteral feeding of VLBWI and ELBWI was not only influenced by maturity of gastrointestinal tract, but also by other parenteral correlation factors. Multiple factors associated with all around clinical conditions should be considered when providing enteral feeding for VLBWI and ELBWI.

Objective To observe the effect of inhaled nitric oxide(INO) on the nitric oxide synthase (NOS) in piglet suffered from severe meconium aspiration syndrome(MAS). Methods Severe MAS model of piglet was reproduced, the oxygenation effect and the activity of pulmonary NOS were measured, hybridization in situ of pulmonary slices was used to show the gene expression of inducible NOS(iNOS). Results INO therapy attenuated respiratory dysfunction in MAS, while discontinuation of INO induced “rebound pulmonary hypertension”. The activity of iNOS in MAS group is higher than that in control group (16.9?3.1) fmol/(mg Pro?min)vs (11.6?2.7) fmol/(mg Pro?min),( P

Objective To discuss the clinical features and possible mechanisms of congenrtal leuleemia spontaneous remission. Methods By means of literature review, 17 cases with spontaneous remission of congenital leukemia were retrospectively analyzed. Results Among the 17 patients, 8 were persistent remission(47%), 9 had late relapses(53%). Neither initial white cell count nor bone marrow involvement was associated with late relapses. 5 cases(29%) had abnormal karyotype and gene rearrangment,11q23 translocation indicated poor prognosis. Conclusions Conservative treatment can be given unless there was evidence of progressive leukemia. Because of occasional late relapses, long term follow-up was recommended. The detection of karyotype and gene rearrangment was a powerful prognostic tool available.
