With the rapid development of assisted reproductive technique (ART),children conceived through ART represent a substantial proportion of the population.Although most researchesonthe safety of A RT offspring are optimistically,it is still worrisome that there are some inconsistent even controversial results.The risk of ARToffspringin perinatal outcomes,birth defects,growth and development,neurological prognosis and imprinting disorders still exist.Therefore,the persistent long-term follow-up of ART children to assess its impact on the long-term prognosis of offspring is particularly important.

Fetal intrauterine growth restriction is one of the common diseases in the perinatal period,which not only increases the child morbidity and mortality in the perinatal period,affecting the long-term development of the nervous system,and can make the risk of adult obesity,hypertension,type Ⅱ diabetes increased significantly.A number of studies suggest that the down-regulation of A amino acid transporter expression is closely associated with intrauterine growth restriction.The down-regulation of A amino acid transporter expression may be an important cause of intrauterine growth restriction.

Objective To investigate the effect of long term intelligence on NGF to the newborn rats with hypoxic ischemic brain damage (HIBD).Methods The model of newborn rat hypoxic ischemic brain damage(HIBD) was set,0.01mg/10g dosage NGF and 0.03mg/10g dosage NGF were administered to the rat abdominal cavity respectively. With maze test, the change of learning memory abilities of long term in the rats were observed, the concentration of monoamine neurotransmitters in the brain tissue were determined by high performance liquid chromatography electrochemical detector.Results The function of learning and memory was better in NGF group(small, large amount group)than in the control group, the frequency was lower remarkably than the control group( P

Antenatal corticosteroid administration to women at risk of preterm delivery within 34 gestational weeks can effectively reduce the incidence of respiratory distress syndrome, intraventricular hemorrhage, and necrotizing enterocolitis in preterm infants. Due to concerns that antenatal corticosteroids may impair the development of the newborn's nervous system, there is a controversy regarding the use of antenatal corticosteroids in pregnant women ≥34 gestational weeks and those with complications. This article reviews the short- and long-term effects of antenatal corticosteroid administration on the nervous system of neonates born to women at different gestational ages and with comorbidities. More and higher-quality evidence is required for routine application of antenatal corticosteroids in pregnant women ≥34 gestational weeks.

Gastroesophageal reflux (GER) was very common among preterm infants, which could cause several complications and severely affects the prognosis. The standardization of diagnosis and treatment of gastroesophageal reflux was very important for preterm infants. Due to less adverse reactions, nonpharmacological therapy was the most advisable choice in preterm infants with GER. In this paper, nonpharmacological therapies including body positioning, feeding frequency and modality, changing food patterns, gastric tube, and nonnutritive sucking were reviewed. Body positioning was the safest and most effective nonpharmacological therapy. Other nonpharmacological strategies such as changes of feeding frequency and modality might also be useful. The role of some strategies was still controversial, thereby needing to be further investigated. Selection of what kind of specific nonpharmacological therapy should be based on the specific conditions.

Nasal continuous positive airway pressure (nCPAP) has been widely used in neonatal respiratory support, but how to successfully withdraw nCPAP has not been further studied, and there is no unified standard of timing and mode of nCPAP weaning.This paper reviews the research progress of nCPAP weaning in premature infants.

Cytomegalovirus infection is one of the most common diseases of newborn viral infection,can cause neurological,digestive,respiratory and blood system damage.In addition to the diagnosis of jaundice,impairment and other clinical manifestations,this disease's diagnosis mainly depend on laboratory examination.Therefore,the application of a sensitive and specific method for early diagnosis of congenital cytomegalovirus(CCMV) infection is particularly important advances in clinical detection method and the research of CCMV infection is reviewed.

In recent years, with the improvement of medical level, central catheter placement is widely used in newborns, especially in infants of very low birth weight and other critical newborns.It effectively reduces the damage of frequent venipuncture and stimulant drugs on blood vessels of children.However, the establishment of neonatal catheter access is closely related to mechanical injury, infection and thrombosis.The use of central catheters is the most common cause of thrombosis in newborns and infants.At present, there are few related reports, and there is no management standard for catheter-related thrombosis in China.This review analyzed the risk factors, diagnosis, prevention and treatment of neonatal catheter-related thrombosis.

OBJECTIVE: To explore the genetic basis for an infant with neonatal diabetes (NDM) and multiple malformations. METHODS: Genetic variants were detected by next generation sequencing (NGS). Suspected variant was verified by Sanger sequencing. RESULTS: A de novo heterozygous variant, c.1454_1455del(p.K485Rfs), was detected in exon 5 of the GATA6 gene. The variant was undetected in his parents and unreported previously. Bioinformatic analysis predicted the variant to be pathogenic. CONCLUSION The heterozygous variant of c.1454_1455del(p.K485Rfs) of the GATA6 gene probably underlies the disease in this child. Genetic testing can facilitate diagnosis and genetic counseling for NDM.

Objective:To construct a Chinese neonatal model of early-onset sepsis (EOS) using the Kaiser Permanente sepsis risk calculator and laboratory indicators and validate its clinical prediction potential.Methods:Newborns with a gestational age of ≥34 weeks, who were hospitalized in the Department of Neonatology, the First Affiliated Hospital of Zhengzhou University from January 2020 to June 2022 were retrospectively recruited.Their clinical data were collected.Predictors were screened via the multivariate regression analysis, and the Nomogram model was constructed using R software and RStudio software.Hosmer-Lemeshow test, receiver operating characteristic curve, the decision curve analysis (DCA) were used to evaluate the prediction potential of the Nomogram.Results:A total of 769 patients were enrolled, including 107 patients in the EOS group (5 culture-confirmed cases and 102 clinically diagnosed cases), and 662 cases in the non-EOS group.Ten variables were screened and introduced into the Nomogram, including the gestational age, birth weight, body temperature, white blood cell count, C-reactive protein, procalcitonin, premature rupture of membranes≥18 h, infection of Group B Streptococcus, ventilator application, and prenatal antibiotics.The predictive model showed good discrimination and consistency, with the area under the curve of 0.834 (95% CI: 0.771-0.896). The DCA of the prediction model showed that it was effective in clinical application within the effective threshold of 6%-95%, with a net benefit following the application of corresponding treatment measures. Conclusions:A Chinese neonatal model of EOS was created by using the Kaiser Permanente sepsis risk calculator and laboratory indicators, which has been validated effective.It provides references for clinical management and the guidance for the use of antibiotics.
