[Clinical and imaging features of premature infants with different degrees of bronchopulmonary dysplasia].

Objective: To study the clinical and imaging features of premature infants with different degrees of bronchopulmonary dysplasia (BPD).

Methods: A prospective study was performed on the clinical data of 59 premature infants (gestational age <32 weeks) with BPD. Among the 59 premature infants, 37 cases had mild BPD and the other 22 cases had moderate to severe BPD.

Diagnosis of neonatal transient tachypnea and its differentiation from respiratory distress syndrome using lung ultrasound.

Transient tachypnea of the newborn (TTN) is one of the most common causes of perinatal dyspnea and is traditionally diagnosed by chest x-ray. This study aimed to explore the diagnostic value of lung ultrasonography (LUS) for TTN as well as differentiate it from respiratory distress syndrome (RDS) by using LUS. From January 2013 to February 2014, 60 infants who were diagnosed with TTN based on medical history, clinical manifestations, arterial blood gas analysis, and chest radiography were recruited to the study group.

BPD, Not BPD, or iatrogenic BPD: findings of lung ultrasound examinations.

Lung ultrasound has been extensively used to diagnose many types of lung disease. This study aimed to evaluate the pulmonary reasons for long-term oxygen dependence (LTOD) in premature infants using lung ultrasound.Lung ultrasound was routinely performed in 50 premature infants clinically diagnosed with bronchopulmonary dysplasia (BPD).

[Therapeutic effect of Ommaya reservoir implantation on hydrocephalus in premature infants following intraventricular hemorrhage and factors associted with the therapeutic effect].

Objective: To observe the therapeutic effect of Ommaya reservoir implantation on hydrocephalus in premature infants following intraventricular hemorrhage (IVH) and to investigate factors influencing the therapeutic effect.

Methods: An ambispective cohort study was conducted on the clinical and follow-up data of 20 premature infants (gestational age <32 weeks, birth weight <1500 g) who received Ommaya reservoir implantation because of hydrocephalus following IVH. The therapeutic effect of Ommaya reservoir implantation was observed.

[Bedside diode laser photocoagulation for 103 cases with serious retinopathy of prematurity in NICU].

Objective: To evaluate the efficacy and safety of the bedside diode laser photocoagulation for severe retinopathy of prematurity in neonatal intensive care unit (NICU).

Method: Data of 103 patients with prethreshold or threshold retinopathy of prematurity (ROP), treated with diode laser photoablation after vecuronium-induced anesthesia and mechanical ventilation from March 2009 to July 2011 in NICU of Bayi Children's Hospital.

Result: Totally 199 eyes in 103 patients received laser therapy with at least 5 months follow up.

[Retinopathy of prematurity screening in 2185 premature infants].

Objective: To determine the incidence and risk factors of retinopathy of prematurity (ROP) among premature infants.

Methods: The fundus examination data of 2185 cases of premature infants [birth body weight ≤ 2000 g or gestational age (GA) ≤ 34 weeks] in neonatal intensive care unit of Bayi Children's Hospitals in Beijing between January 2009 and December 2010 were collected and retrospectively analyzed.

Results: Of 2185 cases of premature infants (1571 had used supplemental oxygen) received RetCam-II ophthalmoscopy screening, 287 cases developed ROP with the incidence of 13.

[Influence of premature rupture of membranes on neonatal health].

Objective: To observe the influence of premature rupture of membranes (PROM) on neonatal health.

Method: A retrospective cohort study was conducted among 3320 in-patient newborns of Bayi Children's Hospital from October 2006 to March 2008. One hundred term newborns and one hundred preterm newborns with PROM were chosen to be compared with fifty normal term newborns and preterm newborns respectively.
