Aim Previous evidence on the relationship between single umbilical artery (SUA) and congenital heart disease (CHD) is controversial. We thus conducted a retrospective study to explore the potential risk factors associated with CHD in SUA fetuses, and verify if all these SUA fetuses should be referred for detail fetal echocardiography. Methods We reviewed medical records of SUA fetuses referred to Xinhua Hospital for fetal echocardiography between September 2009 and February 2014. All the pregnancies were divided into two groups of CHD and non‐CHD according to the results of fetal echocardiography. The maternal and fetal characteristics were compared via χ2 test and Fishers’ test. Furthermore, Poisson regression was used to analyze the risk factors associated with CHD in SUA pregnancies. Results Nineteen CHD cases (12.5%) were detected among 152 SUA fetuses, all with abnormal cardiac views during obstetric screening ultrasound (P < 0.001). χ2 test showed that abnormal cardiac screening findings, extracardiac abnormality and infection or threatened abortion during first trimester were significantly associated with prenatal detection of CHD (P < 0.001). Multivariable Poisson regression after adjustment found that SUA fetuses with extracardiac abnormality had 4.74 (95% confidence interval: 1.89, 11.90) times higher risk of CHD. Conclusion Incidence of CHD was higher in SUA cases, and CHD fetuses could be screened efficiently by abnormal cardiac screening during obstetric screening ultrasound. SUA fetuses with extracardiac abnormality and maternal risk factors have higher risk of CHD, and should be strongly recommended for fetal echocardiography. In contrast, SUA fetuses without above situations might only need routine obstetric follow‐up.
Objectives Cervical cancer (CC) is the common female malignant tumour with non-negligible morbidity and mortality. Eleutheroside E (EE) has anti-oxidative stress, anti-inflammatory and anti-proliferation effects in diverse disease models. However, its anti-tumour role remains unclear. Methods The cell viability, apoptosis rate and protein expressions were detected by CCK-8, flow cytometry and western blot assays, respectively. The metabolic profile was performed by GC/MS analysis. Furthermore, the effect of EE on CC was verified in nude mice. Key findings EE notably decreased the viability and increased the cell apoptosis, which could be reversed with 740Y-P treatment. EE treatment changed the metabolic categories of SiHa cells. The fatty acids signalling pathway was the most outstanding differential pathway. Myo-inositol prominently enhanced the level of phosphorylated Akt in a dose-dependent way. Moreover, EE declined the tumour volume and weight and the proliferation, but promoted the apoptosis in vivo. EE reduced the relative expression of phosphorylated PI3K and Akt. However, all these in-vivo results were observably antagonized with myo-inositol treatment. Conclusions EE plays an anti-tumour role in CC via inhibiting the PI3K pathway and reprogramming the metabolic responses.
