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 [aOR] = 2.12; 95％ confidence interval [CI]: 1.08–4.16), antidepressants (aOR = 2.56; 95％ CI: 1.36–4.82), antiabortifacients (aOR = 1.55; 95％ CI: 1.00–2.40), or traditional Chinese drugs (aOR = 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 CYP450 genetic 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.

目的 探讨焦点解决模式在初次诊断肿瘤患者情绪及应对方式中的应用效果.方法 将2019年3—11月的40例患者作为对照组,2019年12月至2020年8月的40例患者作为试验组.研究过程中失访7例,最终对照组37例,试验组36例.对照组采用常规干预,试验组在对照组干预基础上提供基于焦点解决模式的心理干预,比较两组患者情绪及应对方式.结果 干预后,试验组患者正性情绪评分明显高于对照组,负性情绪评分明显低于对照组,差异均有统计学意义(P﹤0.01).干预后,试验组患者面对、回避评分均明显高于对照组,屈服评分明显
