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.@*RESULTS@#Compared with the group without vitamin D supplementation for the mother (17 neonates), the group with vitamin D supplementation for the mother (79 neonates) had significantly higher levels of total blood calcium and ionized calcium (@*CONCLUSIONS@#Vitamin D supplementation during pregnancy can increase the blood levels of total calcium and ionized calcium in neonates, and calcium supplementation alone cannot increase the blood levels of total calcium or ionized calcium in neonates. Hypothermia in neonates might cause the reduction in blood calcium levels. The urinary calcium level measured by the intelligent urine test system is positively correlated with the blood level of ionized calcium.

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 (0.3 mg/kg), and the control group received intramuscular injection of phenobarbital sodium (10 mg/kg). The sedation status of the neonates was evaluated using the Ramsay Sedation Scale. Meanwhile, the two groups were compared for the success rate of MRI procedure and incidence of adverse reactions.@*RESULTS@#In the observation group, the sedation score was the highest at 20 minutes post administration, then was gradually decreasing, and decreased to the lowest level at 70 minutes post administration. In the control group, the sedation score was the lowest at 10 minutes post administration, then was gradually increasing, and increased to the highest level at 40 minutes and 50 minutes post administration, followed by a gradual decrease. Comparison of the sedation score at each time period suggested that the sedation score was significantly higher in the observation group than in the control group within 40 minutes post administration (P0.05). The success rate of MRI procedure was significantly higher in the observation group than in the control group (89% vs 69%, P0.05).@*CONCLUSIONS@#Intranasal midazolam is superior to intramuscular phenobarbital sodium in the sedative effect in neonates undergoing MRI, with the benefits of being fast, convenient, safe, and effective.

<p><b>OBJECTIVE</b>To study the influence of acute pancreatitis in pregnancy (APIP) on pregnancy outcomes and neonates.</p><p><b>METHODS</b>A retrospective analysis was performed for 33 APIP patients and 31 neonates born alive.</p><p><b>RESULTS</b>Of the 33 APIP patients, 26 (79%) developed APIP in the late pregnancy. Fourteen (45%) patients had hyperlipidemic APIP, 13 (42%) had biliary APIP, and 4 (13%) had other types of APIP. According to the severity, 22 (67%) were mild APIP, 5 (15%) were moderate APIP, and 6 were severe APIP. None of the 33 APIP patients died. Among the 20 patients with term delivery, 11 underwent termination of pregnancy; among the 10 patients with preterm delivery, 9 underwent termination of pregnancy; two patients experienced intrauterine fetal death, and one experienced abortion during the second trimester. Among the 31 neonates born alive (two of them were twins), 1 (3%) died, 12 (39%) experienced neonatal hyperbilirubinemia, 8 (26%) had neonatal hypoglycemia, 6 (19%) had neonatal respiratory distress syndrome, 5 (16%) experienced infectious diseases, and 2 (6%) experienced intracranial hemorrhage. The hyperlipidemic APIP group had a higher percentage of patients undergoing termination of pregnancy than the biliary APIP and other types of APIP groups (P<0.05). The incidence rate of preterm infants in the moderate APIP was higher than in the mild and severe APIP groups (P<0.05). The mean birth weights of neonates were the lowest in the moderate APIP group. The incidence rates of neonatal respiratory distress syndrome, intracranial hemorrhage, and infectious disease were the lowest in the mild APIP group (P<0.05).</p><p><b>CONCLUSIONS</b>APIP can lead to adverse pregnancy outcomes and neonatal diseases, which are associated with the severity of pancreatitis.</p>

After the practical experiences of data literacy education in foreign and domestic academic libraries were summarized and analyzed, the data literacy education was elaborated in aspects of its curriculum, activities, training objects with The Library of Ningxia Medical University as an example in order to provide reference for medical college and university libraries to carry out data literacy education.

<p><b>OBJECTIVE</b>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.</p><p><b>METHOD</b>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. Polymerase chain reaction (PCR) and DNA direct sequencing were performed to screen all exons and their flanking introns of ABCA3 gene for mutation analysis in 11 cases with NRDS. If a new missense variation was identified, single strand conformation polymorphism analysis was performed in 97 healthy controls. Lung tissue sample from a case who died 12 hours after birth was examined with light microscopy and electron microscopy.</p><p><b>RESULT</b>Three missense genetic variants in exons, which include c. 2169 G > A (p.M723I), c. 1010 T > G (p.V337G), c. 4972 A > G (p.S1658G), one splice junction site variation (Exon 30 + 2 T/G), several unreported polymorphism sites [213 C > T(p.F71F), exon 21 + 34C/T] and reported polymorphism site (p.F353F) were identified on ABCA3 gene coding region in 11 case. The homozygous variation (c.2169G > A), which was in exon 17 and causes an M723I amino acid change, was found in the case who died 13 hours after birth, but not detected in 97 controls, indicating that this variation is indeed a mutation and not a polymorphism. In the case carrying c.2169G > A, ultrastructural examination of the alveolar type II cells with electron microscopy demonstrated abnormally small and dense lamellar body with eccentrically distributed electron dense substance.</p><p><b>CONCLUSION</b>Genetic variants within ABCA3 may be the genetic cause of or a contributor to some unexplained refractory NRDS. Identification of ABCA3 genetic variant in NRDS infants is important to establish appropriate management and evaluation of treatment options, as well as to offer genetic counseling and prenatal diagnosis.</p>
