ABSTRACT
OBJECTIVE@#This study aimed to assess the associations between maternal drug use, cytochrome P450 ( CYP450) genetic polymorphisms, and their interactions with the risk of congenital heart defects (CHDs) in offspring.@*METHODS@#A case-control study involving 569 mothers of CHD cases and 652 controls was conducted from November 2017 to January 2020.@*RESULTS@#After adjusting for potential confounding factors, the results show that mothers who used ovulatory drugs (adjusted odds ratio [a OR] = 2.12; 95% confidence interval [ CI]: 1.08-4.16), antidepressants (a OR = 2.56; 95% CI: 1.36-4.82), antiabortifacients (a OR = 1.55; 95% CI: 1.00-2.40), or traditional Chinese drugs (a OR = 1.97; 95% CI: 1.26-3.09) during pregnancy were at a significantly higher risk of CHDs in offspring. Maternal CYP450 genetic polymorphisms at rs1065852 (A/T vs. A/A: OR = 1.53, 95% CI: 1.10-2.14; T/T vs. A/A: OR = 1.57, 95% CI: 1.07-2.31) and rs16947 (G/G vs. C/C: OR = 3.41, 95% CI: 1.82-6.39) were also significantly associated with the risk of CHDs in offspring. Additionally, significant interactions were observed between the CYP450genetic variants and drug use on the development of CHDs.@*CONCLUSIONS@#In those of Chinese descent, ovulatory drugs, antidepressants, antiabortifacients, and traditional Chinese medicines may be associated with the risk of CHDs in offspring. Maternal CYP450 genes may regulate the effects of maternal drug exposure on fetal heart development.

OBJECTIVE@#To study the association between maternal reduced folate carrier (@*METHODS@#A hospital-based case-control study was conducted. The mothers of 683 infants with CHD who attended the Department of Cardiothoracic Surgery, Hunan Children's Hospital, from November 2017 to March 2020 were enrolled as the case group. The mothers of 740 healthy infants without any deformity who attended the hospital during the same period of time were enrolled as the control group. A questionnaire survey was performed to collect the exposure data of subjects. Venous blood samples of 5 mL were collected from the mothers for genetic polymorphism detection. A multivariate logistic regression analysis was used to evaluate the association of @*RESULTS@#After control for confounding factors, the multivariate logistic regression analysis showed that maternal @*CONCLUSIONS@#Maternal

ObjectiveTo investigate the experience in the treatment of acute encephalocele associated with delayed intracranial hematoma during severe brain injury operation.Methods42 patients suffered from acute encephalocele during brain injury operation were,retrospectively analyzed.ResultsAll patients with acute encephalocele were associated with delayed intracranial hematoma.The effective treatment of acute encephalocele was to remove the hematoma out of the brain timely and thoroughly.33 patients survived the disorder of acute encephalocele,of which,good recovery occurred in 20 patients,moderate disability in 6 patients,severe disability in 4 patients,and vegetative state in 3 patients according to Glasgow Outcome Score 3 months later.ConclusionHead-CT scanning should be timely performed when intracperative acute encephalocele occurred,whereas the measures of efficacy improvement on acute encephalocele were to timely.
