A (3,8)-Connected Metal-Organic Framework with Bending Dicarboxylate Linkers for CH/CO Separation.

Herein, by replacement of the linear terephthalate linker with the bending 2,5-thiophenedicarboxylate (tdc) linker in the typical (3,9)-connected metal-organic framework, with a reduced 8-connected hydroxyl-centered trinuclear cluster, a new (3,8)-connected network, [Ni(μ-OH)(tdc)(tpp)] [; tpp = 2,4,6-tris(4-pyridyl)pyridine], was synthesized. The modified pore environment enables to selectively adsorb CH over CO in an efficient manner.

Bi-level Nasal Positive Airway Pressure (BiPAP) versus Nasal Continuous Positive Airway Pressure (CPAP) for Preterm Infants with Birth Weight Less Than 1500 g and Respiratory Distress Syndrome Following INSURE Treatment: A Two-center Randomized Controlled Trial.

The present study aimed to examine the effectiveness of bi-level positive airway pressure (BiPAP) versus continuous positive airway pressure (CPAP) in preterm infants with birth weight less than 1500 g and respiratory distress syndrome (RDS) following intubation-surfactant-extubation (INSURE) treatment. A two-center randomized control trial was performed. The primary outcome was the reintubation rate of infants within 72 h of age after INSURE.

Experience of Clinical Management for Pregnant Women and Newborns with Novel Coronavirus Pneumonia in Tongji Hospital, China.

Based on the New Diagnosis and Treatment Scheme for Novel Coronavirus Infected Pneumonia (Trial Edition 5), combined with our current clinical treatment experience, we recently proposed a revision of the first edition of "Guidance for maternal and fetal management during pneumonia epidemics of novel coronavirus infection in the Wuhan Tongji Hospital". This article focused on the issues of greatest concern of pregnant women including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection diagnostic criteria, inspection precautions, drug treatment options, indications and methods of termination of pregnancy, postpartum fever, breastfeeding considerations, mode of mother-to-child transmission, neonatal isolation and advice on neonatal nursing, to provide valuable experience for better management of SARS-CoV-2 infection in pregnant women and newborns.

Correlation between UGT1A1 polymorphism and neonatal hyperbilirubinemia of neonates in Wuhan.

This study attempts to discuss the correlation between UGT1A1*28 as uridine diphosphate glucuronosyltransferase gene promoter and coding region Gly71Arg gene polymorphism with neonatal hyperbilirubinemia of neonates in Wuhan. A total of 168 neonates were divided into the hyperbilirubinemia group (case group, n=108) and healthy neonates group (control group, n=60). Their DNA was obtained through blood extraction.

Nasal bi-level positive airway pressure (BiPAP) versus nasal continuous positive airway pressure (CPAP) in preterm infants ≤32 weeks: A retrospective cohort study.

Aim: To investigate whether Bi-level positive airway pressure (BiPAP), compared with nasal continuous positive airway pressure (CPAP), is a more effective therapeutic strategy in preterm infants ≤32 weeks.

Methods: All inborn infants between 26(+1) and 32(+6) weeks' gestation, admitted to the neonatal intensive care unit (NICU ) of Tongji Medical Hospital between 1 January, 2010 and 31 December, 2011 (the 2010-2011 cohort or CPAP cohort) and between 1 January, 2012 and 31 December, 2013 (the 2012-2013 cohort or BiPAP cohort), were retrospectively identified. The primary outcome was intubation in infants < 72 h of age; secondary outcomes were mortality and the incidence of bronchopulmonary dysplasia (BPD).

[Protective effects of IGF-1 on cortical nerve cells of neonatal rats under oxidative stress].

Objective: To investigate the protective effects of insulin-like growth factor-1 (IGF-1) on the nerve cells of neonatal rats under oxidative stress.

Methods: Primary cortical neurons, oligodendrocytes, and astrocytes from newborn rats were cultured. An oxidative stress model was established with different concentrations of H2O2 (0-60 μmol/L); the degree of damage of nerve cells was evaluated by lactate dehydrogenase assay, and the viability of nerve cells was tested by MTT assay.

[Retinoic acid diminished the expression of lung tissue matrix metalloproteinase-2 and matrix metalloproteinase-9 in hyperoxia-exposed premature rats through regulating mitogen-activated protein kinases].

Objective: To further investigate the protective effect of retinoic acid (RA) on hyperoxia induced lung injury and the role of RA as a modulator on mitogen-activated protein kinases (MAPKs).

Methods: Establishment of hyperoxia (85%) induced lung injury model of premature Sprague-Dawley (SD) rats: 21 d gestational age SD rat's fetuses (term = 22 d) were delivered by hysterectomy. Within 12 - 24 h after birth, the premature rat pups were randomly divided into 4 groups: Group I, air-exposed control group; Group II, hyperoxia-exposed group; Group III, air plus RA-exposed group, Group IV, hyperoxia plus RA-exposed group.

[Relation of insulin-like growth factor binding protein-2 with hyperoxia-induced lung injury in term and premature neonatal rats].

Objective: To study the deleterious effect of prolonged hyperoxic exposure on term and premature neonatal rat lungs and investigate the relationship between insulin-like growth factor binding protein (IGFBP)-2 and hyperoxia-induced lung injury in neonatal rats.

Methods: At the 22nd postnatal day Sprague-Dawley (SD) term-newborn or preterm-newborn rats were randomly divided into 4 groups. group I: term-rats+air group; group II: term-rats+hyperoxia group; group III: preterm-rats+air group; group IV: preterm-rats+hyperoxia group.
