Aspirin versus metformin in pregnancies at high risk of preterm pre-eclampsia in China (AVERT): protocol for a multicentre, double-blind, 3-arm randomised controlled trial.

Introduction: Pre-eclampsia (PE) affects about 5% of Chinese pregnant women and is a major cause of maternal and perinatal morbidity and mortality. The first trimester screening model developed by the Fetal Medicine Foundation, which uses the Bayes theorem to combine maternal characteristics and medical history together with measurements of biomarkers, has been proven to be effective and has superior screening performance to that of the traditional risk factor-based approach for the prediction of PE. Prophylactic use of low-dose aspirin in women at risk for PE has resulted in a lower incidence of preterm-PE.

Changes in the characteristics and outcomes of high-risk pregnant women who delivered prior to and after China's universal two-child policy: a real-world retrospective study, 2010-2021.

Background: In 2016, the "universal two-child" policy, allowing each couple to have two children, was introduced in China. The characteristic change of the long-term period after the implementation of the universal two-child policy was unclear. We studied trends in the obstetric characteristics and their potential impact on the rates of cesarean section and preterm birth in the era of China's universal two-child policy.

Adoption value of support vector machine algorithm-based computed tomography imaging in the diagnosis of secondary pulmonary fungal infections in patients with malignant hematological disorders.

This study aimed to assess the feasibility of diagnosing secondary pulmonary fungal infections (PFIs) in patients with hematological malignancies (HM) using computerized tomography (CT) imaging and a support vector machine (SVM) algorithm. A total of 100 patients with HM complicated by secondary PFI underwent CT scans, and they were included in the training group. Concurrently, 80 patients with the same underlying disease who were treated at our institution were included in the test group.

[Important Considerations of Low-Dose Aspirin in the Prevention of Preeclampsia].

Low-dose prophylactic aspirin is widely recommended for pregnant women for the prevention of preeclampsia (PE). Although the efficacy of aspirin in preventing PE has been evaluated in many studies, due to the differences in dosage, initiation time, and screening methods for the identification of women at high risk of PE and the lack of a uniform opinion on the medication regimen of aspirin, currently in China there is no consensus on the standardized treatment scheme of aspirin for the prevention of PE in clinical guidelines. Herein, we reviewed the current available evidence and the recommendations of clinical guidelines concerning the controversies about aspirin dosage as well as the timing of starting and stopping aspirin, so as to provide further guidance for clinical practice.

Longitudinal trends in lipid profiles during pregnancy: Association with gestational diabetes mellitus and longitudinal trends in insulin indices.

Objective: To investigate the correlation of trends in lipid profiles from first to second trimester with trends in insulin indices and gestational diabetes mellitus (GDM).

Calpain-2 Facilitates Autophagic/Lysosomal Defects and Apoptosis in ARPE-19 Cells and Rats Induced by Exosomes from RPE Cells under NaIO Stimulation.

Although accumulated evidence supports the notion that calpain contributes to eye disease, the mechanisms by which calpain promotes RPE injury are not defined. The present study is aimed at investigating whether the effect of NaIO-exos (exosomes derived from RPE cells under NaIO stimulation) on the dysfunction of the autophagy-lysosomal pathway (ALP) and apoptosis is based on its regulation of calpain activation in ARPE-19 cells and rats. The results showed that calpain-2 activation, ALP dysfunction, and apoptosis were induced by NaIO-exos in ARPE-19 cells.

Optical coherence tomography angiography for the characterisation of retinal microvasculature alterations in pregnant patients with anaemia: a nested case‒control study.

Methods: This nested case‒control study included singleton PA and HC from the Eye Health in Pregnancy Study. Fovea avascular zone (FAZ) metrics, perfusion density (PD) in the superficial capillary plexus, deep capillary plexus and flow deficit (FD) density in the choriocapillaris (CC) were quantified using FIJI software.

Design, Preparation, and Evaluation of Osthol Poly-Butyl-Cyanoacrylate Nanoparticles with Improved In Vitro Anticancer Activity in Neuroblastoma Treatment.

Osthol (osthole), known as a neuroprotective drug, has shown potent anticancer activity. However, the potential clinical application of osthol is limited due to its low water solubility and low bioavailability. Polybutyl cyanoacrylate (PBCA) has been widely used to improve the solubility of drugs with poor water solubility.

Screening for spontaneous preterm birth by cervical length and shear-wave elastography in the first trimester of pregnancy.

Background: First-trimester cervical length for the prediction of spontaneous preterm delivery remains controversial. A better method for the measurement of the first-trimester cervical length and additional cervical ultrasound parameters for the identification of women at high risk for spontaneous preterm delivery are needed.

Objective: This study aimed to compare the predictive value of cervical length measured by 2 different methods in the first trimester of pregnancy to predict spontaneous preterm delivery and to explore the potential value of first-trimester cervical shear-wave elastography for the prediction of spontaneous preterm delivery.

Sex differences in the pharmacokinetics and tissue residues of extracts in rats.

AB4 inhibits Notch signaling and promotes cancer cell apoptosis in liver cancer.

The etiology for liver cancer has been clearly defined. Unfortunately, therapeutic approaches for liver cancer are rather limited, and liver cancer is insensitive to chemotherapy and radiotherapy. Traditional Chinese medicine (TCM) has become a promising strategy for cancer treatment as TCM elicits broad spectrum anticancer activity.

[Determination of physiological indices in early kernel at different ear position in maize (Zea mays L.) with UV-visible spectrophotometry].

To examine the difference between early kernels at different ear position in maize and the effect of nitrogen supply rates on kernel development, physiological indices in apical and mid-basal kernel 5-20 days after pollination in maize under different nitrogen supply rates (0, 120, 180 and 240 kg x ha(-1)) were determined with UV-Vis spectrophotometry. The results showed that nitrogen supply obviously increased the contents of soluble sugar, sucrose and starch, and the activities of enzymes related to sucrose inversion and starch synthesis. Twenty days after pollination, the kernel volume, dry weight and the contents of soluble sugar, sucrose and starch in apical kernel under nitrogen supply rate of 180 kg x ha(-1) were higher than those with other treatments.
