[Clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation: a multicenter retrospective analysis].

Objective: To evaluate the clinical features of preterm infants with a birth weight less than 1 500 g undergoing different intensities of resuscitation.

Methods: A retrospective analysis was performed for the preterm infants with a birth weight less than 1 500 g and a gestational age less than 32 weeks who were treated in the neonatal intensive care unit of 20 hospitals in Jiangsu, China from January 2018 to December 2019. According to the intensity of resuscitation in the delivery room, the infants were divided into three groups:non-tracheal intubation (=1 184), tracheal intubation (=166), and extensive cardiopulmonary resuscitation (ECPR; =116).

Effect of low intensity pulsed ultrasound on repairing the periodontal bone of Beagle canines.

Objective: To investigate the repairing effect of low intensity pulsed ultrasound (LIPUS) on the Beagle canines periodontal bone defect.

Methods: A total of 12 Beagle dogs with periodontal bone defect model were randomly divided into control group, LIPUS group, guided tissue regeneration (GTR) group and LIPUS+GTR group, with three in each. After completion of the models, no other proceeding was performed in control group; LIPUS group adopt direct exposure to radiation line LIPUS processing 1 week after modeling; GTR group adopted treatment with GTR, following the CTR standard operation reference; LIPUS+GTR group was treated with LIPUS joint GTR.

Breast milk lead and cadmium levels in suburban areas of Nanjing, China.

Objective: To evaluate levels of lead (Pb) and cadmium (Cd) in the breast milk in the second postpartum month, to investigate the relationship between Pb/Cd levels in breast milk and some sociodemographic parameters, and to explore whether these levels affect the infants' physical status or the mothers' psychological status (postpartum depression).

Methods: A cross-sectional study was conducted between November 2009 and December 2010. Altogether 170 healthy mothers were enrolled from Nanjing Maternity and Child Health Care Hospital.

[Effects of maternal deficiency of folic acid during pregnancy on pulmonary development and SP-A expression in newborn rats].

Objective: This study examined the effects of maternal deficiency of folic acid during pregnancy on pulmonary development and protein A (SP-A) expression in newborn rats in order to explore the possible mechanism of lung developmental disorders.

Methods: Thirty-six adult Sprague-Dawley female rats were randomly assigned into two groups: control and study (n=18). The study and the control groups were fed with fodder containing folic acid or not respectively.

Epidural analgesia in the latent phase of labor and the risk of cesarean delivery: a five-year randomized controlled trial.

Background: The optimal timing of epidural analgesia has been a controversial issue, and how early women can benefit from epidural analgesia is still debated. The objective of this trial was to test the hypothesis that patient-controlled epidural analgesia given at cervical dilation of 1.0 cm or more does not increase the risk of prolonged labor or Cesarean delivery.

Folbp1 promotes embryonic myocardial cell proliferation and apoptosis through the WNT signal transduction pathway.

The aim of this study was to evaluate the relationship between Folate-binding protein one (Folbp1) and embryonic cardiac proliferation, apoptosis, and differentiation. Folbp1 gene expression and short interference RNA expression vectors were constructed. Morphology of P19 cells during differentiation was observed by inverted microscope.
