[Establishment of regional active neonatal transport network].

Objective: To evaluate the clinical function and significance of establishing a regional active neonatal transport network (ANTN) in Beijing.

Method: The authors retrospectively studied intensive care and the role of ANTN system in management of critically ill neonates and compared the outcome of newborn infants transported to our NICU before and after we established standardized NICU and ANTN system (phase 1: July 2004 to June 2006 vs phase 2: July 2006 to May 2008).

Result: The number of neonatal transport significantly increased from 587 during phase 1 to 2797 during phase 2.

[Effect of basic fibroblast growth factor on expression of protein and mRNA of bone morphogenetic protein 4 in hypoxic-ischemic brain damage in newborn rats].

Objective: To investigate the effect of basic fibroblast growth factor(bFGF) on expression of protein and mRNA of bone morphogenetic protein 4 in hypoxic-ischemic brain damage (HIBD) in newborn rats.

Method: One hundred and twenty 7 days old neonatal rats were randomly divided into control group, hypoxic-ischemic brain damage and interventional group of bFGF, each having forty neonatal rats. After HIBD model was established, bFGF was given to interventional group by peritoneal injection for 5 continuous days.

[Preliminary study on maturity of retinal vascularization in premature infants].

Objective: To study the extent of retinal vascular development and influencing factors at birth and the relation between retinal vascularization and retinopathy of prematurity (ROP).

Methods: From October, 2006 to December 2006, retinal vascularization was screened and evaluated in 84 neonates at different weeks of gestation and birth weights (BWs), had dilated fundus evaluation for zone of retinal vascularization by the 130 degrees lens of a digital fundus camera. The infants' pupils were dilated with 2.

[Relationship between reduced expression of surfactant protein B and neonatal respiratory distress syndrome in twenty Han ethnic group neonates in China].

Objective: To investigate possible relationship between expression of surfactant protein B (SP-B) gene product and neonatal respiratory distress syndrome (NRDS) in Han ethnic group.

Method: Unrelated 20 cases with NRDS of Han ethnic group were selected as NRDS group while unrelated 20 diseases cases of Han ethnic group with diseases were selected as control group. The cases in the control group had congenital heart disease or bronchopulmonary dysplasia or persistent pulmonary hypertension.

[A multivariate analysis of prevalence and risk factors of retinopathy of prematurity].

Objective: To investigate the prevalence and risk factors of retinopathy of prematurity (ROP).

Methods: This investigation involved 125 premature infants admitted in the neonate intensive unit between July 1st, 2006 and Feb 1st, 2007, who were less than 37 weeks of postconceptional age, or more than 37 weeks but with birth weight <2500 g. At the fourth postnatal week or the corrected gestational age of 32 to 34 weeks, the infants underwent ROP examination of both eyes using RetCam digital retinal camera.
