Objective To determine the effects of feeding donor human milk versus formula milk on very low birth weight infants (VLBWI) and extremely low birth weight infants (ELBWI).Methods The Cochrane library,PubMed,EMBASE,Wanfang,CNKI and VIP database were searched for the randomized controlled trials (RCT) that compare donor human milk with formula milk in VLBWI and ELBWI from the establishment of database up to February 2014.The quality of the included studies was assessed.Meta analysis was performed using RevMan 5.2.9 software.The results were expressed by mean difference (MD) and 95％CI for continuous variables,RR and 95％CI for categorical variables.Results Only five trials were included:in quality evaluation,two trials were graded B,and the other three were graded C.Meta-analysis showed that,compared with the formula milk,feeding of donor human milk could reduce the risk ofnecrotizing enterocolitis (RR=0.36,95％CI:0.18-0.73,P＜0.01),but not the risks of sepsis (RR=0.92,95％CI:0.50 1.72,P=0.80),retinopathy of prematurity (RR=1.21,95％CI:0.84-1.74,P=0.31) and in-hospital mortality (RR=0.66,95％CI:0.18-2.37,P=0.52).The significantly lower rates in weight gains in neonatal period (MD=-6.58,95％CI:-11.19 to-1.98,P＜0.01) and body length (MD=-0.30,95％CI:-0.41 to-0.20,P＜0.01)were found in donor human milk compared with formula milk.No significant difference in head circumference (MD=-0.16,95％CI:-0.33 to 0.01,P=0.13) was seen in comparison of donor human milk with formula milk.Conclusions Feeding with donor human milk can reduce the risk ofnecrotizing enterocolitis in VLBWI and ELBWI,but its effects on neonatal growth need to be further studied in large scale RCT.

Objective To systematically evaluate the effectiveness of delayed cord clamping (DCC) in term infants. Methods The data of the Cochrane library, PubMed, EMBASE, CNKI , VIP, Wanfang from 1 January 1970 to 30 April 2013 were searched. Randomized controlled trials (RCT) of DCC in term infants were included.RevMan 5.1.0 was used in the statis-tical analysis. Results Ten studies involving 1623 participants were included. Meta-analysis based on included studies showed that:compared with immediate cord clamping (ICC), DCC improved the hemoglobin levels at birth (MD=2.19, 95%CI:0.36, 4.02) and increased the incidence of polycythaemia (RR=2.87, 95%CI:1.24, 6.62). Compared with ICC, DCC showed no signi-ficant difference in the phototherapy for hyperbilirubinemia (RR=2.46, 95%CI: 0.93, 6.52), the hemoglobin levels within 6 months (MD=0.29, 95%CI:-0.17, 0.75), and the incidence of anemia (RR=0.71, 95%CI:0.45, 1.12). Conclusions DCC can improve the hemoglobin level in term infants after birth. However, the appropriate time of cord clamping has not been deter-mined. It is necessary to undertake further studies with higher quality and larger scale to evaluate the optimal time of cord clam-ping.

BACKGROUND: Intrapulmonary vascular abnormalities result in the right-to-left shunting and severe hypoxemia in liver transplantation candidates. Currently, a convenient, sensitive and effective method is absent to screen the intrapulmonary vascular dilatations.OBJECTIVE: To evaluate the role of contrast-enhanced echocardiography on clinical diagnosis of intrapulmonary shunting in liver transplantation candidates.DESIGN, TIME AND SETTING: The experiment, prospective controlled observation based on cases, was performed at the Hepatology Unit of the 458 Hospital of PLA (Guangzhou, Guangdong, China) from February 2004 to February 2006.PARTICIPANTS: Twenty-four consecutive liver transplantation candidates were recruited from the Hepatology Unit of the 458Hospital of PLA.METHODS: Routine examination was conducted under the condition without any regimen of vascular dilatation drugs.Contrast-enhanced echocardiography was applied to detect the prevalence of right-to-left shunting in the patients with end-stage liver disease. The microvesicle of the left ventricle in patients was qualitatively assessed by a score from 1+ to 3+. Accordingly, all patients were divided into two groups: intrapulmonary shunting and non-intrapulmonary shunting.MAIN OUTCOME MEASURES: The prevalence of right-to-left shunting and clinical characteristics of liver transplantation candidates were determined.RESULTS: Ten (41.7%) of 24 patients with positive contrast-enhanced echocardiography were proved to develop the intrapulmonary right-to-left shunting, including 6 for l+ and 4 for 2+ by left ventricle abnormality, which emerged after 6-10 cardiac cycles of right ventricle abnormality. There were no significant differences in age, gender, arterial blood gas analysis and liver function tests between the two groups (P > 0.05). Echocardiography results demonstrated that, the upper digestive tract hemorrhage,spleen thickness that indicated portal hypertension, pulmonary artery systolic pressure and Tei index were significandy higher in the patients of intrapulmonary shunting than in those of non-intrapulmonary shunting (P<0.05-0.01 ).CONCLUSION: Intrapulmonary vascular dilatation occurs frequently in liver transplantation candidates associated with intrapulmonary shunting but without hypoxemia. Contrast-enhanced echocardiography is a sensitive and non-invasive method for the early diagnosis of intrapulmonary vascular dilatation. The pathogenic cause is portal hypertension. Tel index can be used as an important parameter for evaluating right ventricular function in patients of intrapulmonary vascular dilatation.

Objective To evaluate the predictive accuracy of several risk-assessment strategies to predict the risk of significant neonatal hyperbilirubinemia, and to establish the best prediction model.Methods The transcutancous bilirubin (TcB) levels of 4907 term and near-team infants were measured.Trace blood bilirubin levels of the infants whose TcB levels ≥250 μmol/L were detected. Clinical data of newborns and their mothers were collected and were analyzed with Logistic regression model to investigate its correlation with signifrcant hyperbilirubinemia. Clinical high risk factors of significant neonatal hyperbilirubinemia were determined. Accuracy of three prediction methods for significant hyperbilirubinemia was compared by receiver operating characteristic (ROC) curve. The three methods included: whether predischarge bilirubin level (within 72 hours after birth) expressed in risk zone on an hour-specific bilirubin nomogram; clinical risk factors other than predischarge bilirubin level; and combination of the predischarge bilirubin risk zone and other clinical risk factors. Results Two hundred and eighty-six newborns (5.8%) were found with significant hyperbilirubinemia. The risk factors of significant neonatal hyperbilirubinemia were divided into three groups according to OR: (1) Major risk factors:predischarge (within 72 hours after birth) bilirubin level in the high risk-zone (OR=96. 39, 95% CI:53.32-174.27, P = 0. 000), large cephalohematoma (OR = 36.45, 95% CI: 10. 02-132.56,P=0. 0076), gestational age 35-36+6 weeks (OR= 30. 72, 95% CI 14.47-65.23, P=0. 0001) and exclusive breast feeding and weight loss was ＞9% of birth-weight (OR=22.44, 95% CI: 4.42-114. 03, P=0. 0016). (2) Minor risk factors: gestational age 37-37+6 weeks (OR=3.26, 95% CI:1.92-5. 55, P=0. 0232), predischarge bilirubin level in P76-P95(OR=13. 64, 95% CI: 8. 10-22.97,P=0. 0001) and bruising (OR = 2.32, 95% CI: 1.14-4.71, P = 0. 0497). (3)Protective factors (those factors associated with decreased risk of hyperbilirubinemia): predischarge bilirubin level in low-risk zone (≤P40) (OR=0. 00), gestational age ≥40 weeks (OR=0.21, 95% CI: 0.09-0.44,P=0. 0402) and mixed breeding (OR=0. 75, 95% CI: 0. 58-0.95, P=0.0059). The area under the ROC curve of predischarge bilirubin level was 0. 8687 and 0. 7375 for clinical risk factors other than predischarge bilirubin level. The area under the ROC curve of a combination of the predischarge bilirubin risk zone and additional clinical risk factors was 0. 9367. Conclusions The risk of significant neonatal hyperbilirubinemia could be simply and accurately predicted by infant's predischarge bilirubin level and the combination of predischarge bilirubin level, and clinical risk factors might improve the accuracy of prediction significantly.

Objective To analyze the relationship between knowledge on cardiovascular disease prevention and ideal cardiovascular health behaviors and factors in community elderly. Methods From December, 2015 to May, 2016, totally 400 elderly in communities with-out overt cardiovascular disease were conveniently sampled. The level of knowledge on cardiovascular disease prevention was measured by self-designed cardiovascular disease prevention questionnaire. And each of the ideal cardiovascular health components was collected. Re-sults A total of 390 responses were valid. 13.85%community elderly were with high level of the knowledge. There were significant differ-ences in the distribution of cardiovascular health indexes among various leves of the knowledge groups (χ2>9.974, P<0.05), except choles-terol (P>0.05). The level of the knowledge was positively correlated with the scores of cardiovascular health behaviors and health factors (r>0.354, P<0.01). The cardiovascular health score, health behaviors score, health factors score and number of ideal cardiovascular health in-dexes were significantly different among various levels of the knowledge groups (F>8.961, P<0.001). Conclusion The level of knowledge on cardiovascular disease prevention was positively correlated with cardiovascular health behavior and health factors. The scores of cardio-vascular health score, health behaviors score and health factors increased with the improvement of knowledge on cardiovascular disease pre-vention.
