Primary repair of esophageal atresia gross type C thoracoscopic magnetic compression anastomosis: A case report.

Background: Esophageal atresia (EA) is a life-threatening congenital malformation in newborns, and the traditional repair approaches pose technical challenges and are extremely invasive. Therefore, surgeons have been actively investigating new minimally invasive techniques to address this issue. Magnetic compression anastomosis has been reported in several studies for its potential in repairing EA.

[Association of neonatal blood calcium levels with perinatal factors and neonatal urinary calcium levels measured by an intelligent urine test system].

Objective: To study the association of neonatal blood calcium levels with perinatal factors and neonatal urinary calcium levels measured by an intelligent urine test system.

Methods: The medical data of 96 full-term singleton neonates with mild diseases were collected by a cross-sectional survey, who were hospitalized in the Department of Neonatology, The First Affiliated Hospital of Xi'an Jiaotong University, from June to August 2018. Urinary calcium levels measured by an intelligent urine test system, total blood calcium levels, ionized calcium levels, and the mother's calcium and vitamin D supplementation during pregnancy were recorded.

[Sedative effect of intranasal midazolam in neonates undergoing magnetic resonance imaging: a prospective single-blind randomized controlled study].

Objective: To compare intranasal midazolam and intramuscular phenobarbital sodium for their sedative effect in neonates undergoing magnetic resonance imaging (MRI).

Methods: A total of 70 neonates who underwent cranial MRI from September 2017 to March 2019 were randomized into an observation group and a control group, with 35 cases in each group. The observation group received intranasal drops of midazolam (0.

[Influence of acute pancreatitis in pregnancy on pregnancy outcomes and neonates].

Objective: To study the influence of acute pancreatitis in pregnancy (APIP) on pregnancy outcomes and neonates.

Methods: A retrospective analysis was performed for 33 APIP patients and 31 neonates born alive.

Results: Of the 33 APIP patients, 26 (79%) developed APIP in the late pregnancy.

[Monomer conversion effect of post-cure treatment on light-cured composite resin].

Purpose: To study the influence of post-cure treatment on the monomer conversion of 3 light-cured composite resins.

Methods: Three kinds of light-cured composite resin: CHARISMA, DenFilTM Flow and nano-hydroxyapatite composite resin were double-side cured for 40 s. The materials without any secondary treatment were used as control group (group A).

[Bonding performance evaluation between the new nano-hydroxyapatite composite resin and dentin].

Purpose: To evaluate the shear bond strength and bonding ability between the new nano-hydroxyapatite composite resin and tooth structure.

Methods: Thirty-six healthy isolated molars were randomly assigned to 3 groups according to the material employed: new nano-hydroxyapatite composite resin, composite resin karisma and glass ionomer cement. After thermal cycling, the data of shear bond strength was recorded, and the type of specimen fracture section was observed under stereo microscope.

[Study on the fluorescence properties of carbon dots prepared by one step microwave method].

In recent years, more and more researchers pay attention to the synthesis of water-soluble fluorescent carbon dots. Compared with the traditional cadmium-based, silicon-based quantum dots and organic dyes, carbon dots with low toxicity and high stability can be chemically modified and be compatible with a variety of organic, inorganic, and biological molecules, and can be applied in many areas. The fluorescence carbon dots were prepared by one step microwave method using ascorbic acid as raw materials.

[Detection of genetic defect within ABCA3 from newborns with respiratory distress syndrome].

Objective: To detect possible relationship between genetic defect within the gene encoding member A3 of the ATP Binding Cassette family (ABCA3) and neonatal respiratory distress syndrome (NRDS), thus to understand the genetic mechanisms of NRDS in Han ethnic group.

Method: The clinical data of 11 cases with NRDS hospitalized in neonatal intensive care unit was investigated. Blood samples were collected from 11 cases with NRDS and 97 unassociated normal individuals.
