Objective To study the protective effect of interleukin-22 (IL-22) against the hyperoxia-induced lung injury in neonatal SD rats. Methods The neonatal SD rats were randomized into control group, hyperoxia group and IL-22 (10 ng/g) treatment group. Each group was randomly divided into three subgroups of 1, 3, 7 days (n=9). Body mass in every group was(More)
Background: Results from experimental and clinical studies have shown that mechanical ventilation or/and hyperoxia may aggravate a pre-existing lung injury or even cause lung injury in healthy lungs by affecting the expression of MMP-9, but the MMP-9 effects are controversial. How are MMP-9 regulated when multicausative factors of injury such as different(More)
OBJECTIVE To investigate the changes of Wnt7b/β-catenin signaling pathway molecules in the differentiation of fetal rat alveolar epithelial type II cells (fAEC2). METHODS Fetal rat lung tissues were extracted from pregnant SD rats (19 days), and then fAEC2 were isolated and purified. After fAEC2 were cultured for 48, 72, 96 hours, the morphological(More)
BACKGROUND Breast feeding can enhance preterm infants' neurodevelopmental outcome, regulate immune function development. This study aims to develop breastfeeding evaluation indicators system in neonatal intensive care units (NICU) and to provide theoretical basis for all-round evaluation of breast feeding quality for hospitalized preterm infants.

BACKGROUND/AIM To investigate the effects of keratinocyte growth factor (KGF) on the growth and transdifferentiation of primary alveolar epithelial type II cells (AECIIs). MATERIALS AND METHODS The number of primary AECIIs, their viability, and cell cycle and apoptosis were studied under KGF treatment using a hemocytometer, trypan blue exclusion, and flow(More)
OBJECTIVE To probe into therapeutic effect and its mechanism of "Huo Xue Bu Qi Fang" (HXBQF) on fetal rats with intrauterine growth retardation (IUGR). METHOD The model of pregnant rat with IUGR was established by passive smoking method. Forty pregnant rats with IUGR were randomly divided into intervention group (with high-, middle- and low-dose Chinese(More)
