    Abstract Axially chiral diaryl ethers are present in numerous natural products and bioactive molecules. However, only few catalytic enantioselective approaches have been established to access diaryl ether atropisomers. Herein, we report the N-heterocyclic carbene-catalyzed enantioselective synthesis of axially chiral diaryl ethers via desymmetrization of prochiral 2-aryloxyisophthalaldehydes with aliphatic alcohols, phenol derivatives, and heteroaromatic amines. This reaction features mild reaction conditions, good functional group tolerance, broad substrate scope and excellent enantioselectivity. The utility of this methodology is illustrated by late-stage functionalization, gram-scale synthesis, and diverse enantioretentive transformations. Control experiments and DFT calculations support the association of NHC-catalyzed desymmetrization with following kinetic resolution to enhance the enantioselectivity.

    Abstract Vitamin D has received increasing attention because of its association with atopic disease development. Limited studies that have been done on the impact of maternal vitamin D levels during pregnancy on infantile eczema are still debatable. We wanted to discover the effect of maternal vitamin D on infantile eczema and explore whether regulatory T cells (Treg) play a role in this process. 219 pairs of mothers and children were enrolled. Maternal fasting venous blood was collected in pregnancy's second and third trimesters to determine vitamin D levels. Cord blood and placenta samples were collected during childbirth for detecting levels of genes, proteins and cytokines. Pediatricians followed up the prevalence of eczema in infants within 1 year. The reported rate of vitamin D deficiency and insufficiency was 35.6% and 28.3%. Lower maternal 25(OH)D

    Abstract Background: Exosomal miRNAs play crucial roles in many central nervous system diseases. Cerebral small vessel disease (CVSD) is a small vessel disease that is affected by various factors. This study aimed to investigate the role of exosomal miR-320e in the Wnt/β-catenin pathway stimulated by oxidative stress and assess its clinical correlation with psychiatric symptoms in patients with CVSD.
    Aim: To explore whether exosomal miR-320e could suppress the Wnt/β-catenin pathway and play a protective role in CVSD progression, as well as examine its potential correlation with cognitive impairment and depression in patients with CVSD.
    Methods: Differentially expressed exosomal miRNAs were filtered by sequencing plasma exosomes from patients with CVSD and healthy controls. Bioinformatics and dual luciferase analyses were used to confirm the binding of miR-320e to Wnt2, and the mRNA and protein levels of downstream components in the Wnt/β-catenin pathway were evaluated when overexpressed or with knockdown of miR-320e under H
    Results: High-throughput sequencing revealed that exosomal miR-320e was downregulated in patients with CVSD. Bioinformatics analysis and dual-luciferase reporter gene experiments showed that exosomal miR-320e inhibited the Wnt/β-catenin pathway in response to oxidative stress by targeting the 3' noncoding region of Wnt2. Uptake of exosomes carrying miR-320e into endothelial cells could also target Wnt2 and inhibit the Wnt2/β-catenin pathway. Elevated miR-320e expression may protect patients with CVSD from relatively severe cognitive impairment and depression, as it was found to have a positive correlation with the MoCA/EFA and HAMD/BDI scores.
    Conclusion: Our results suggest that exosomal miR-320e suppresses the Wnt/β-catenin pathway and may play a protective role in CVSD progression.

    Abstract Background and objective: Most evidence suggests that the pharmacokinetics of monoclonal antibodies (mAbs) are not meaningfully altered by patient characteristics, including racial/ethnic differences. Nevertheless, the pharmacokinetic profile of eptinezumab has not been evaluated in a Chinese population. This study was designed to confirm the hypothesis that the pharmacokinetic profile of the anti-calcitonin gene-related peptide mAb, eptinezumab, is similar in healthy Chinese individuals to that of healthy non-Asian individuals and non-Asian patients with migraine.
    Methods: Over a study period of 12 weeks, healthy adult Chinese participants (N = 20) were randomized (1:1) to receive a single intravenous dose of eptinezumab 100 mg (n = 10) or 300 mg (n = 10) in a prospective, single-site, open-label parallel-group trial. Blood samples for the evaluation of plasma eptinezumab concentrations were obtained over 84 days, and standard pharmacokinetic parameters were derived.
    Results: Mean maximum plasma concentrations (C
    Conclusion: The pharmacokinetic profile of eptinezumab in healthy Chinese individuals was generally similar to that reported for non-Asian populations with migraine, and eptinezumab was generally well tolerated. Evaluation of immunogenicity showed no evidence of an impact of anti-drug antibodies or neutralizing antibodies on safety profiles. This supports the globally approved doses of 100 mg and 300 mg as being appropriate for Chinese patients with episodic migraine or chronic migraine.

    Abstract Objective: To investigate the lead exposure levels, and the effect of blood lead level (BLL) on recurrent respiratory infections in children aged 3-7 years in Shenyang.
    Methods: A case-control study including 78 children with recurrent respiratory infections and 141 controls was performed. Venous blood was obtained for BLL, and a questionnaire was completed.
    Results: The BLL was significantly higher in children with recurrent respiratory infections than that in the control group [Median (IQR): 2.56 (1.29-6.19) vs 1.99 (0.90-5.92) µg/dL, P=0.029]. Children with BLL ≥1.95 µg/dL were more likely to be suffering from recurrent respiratory infections (OR=2.328, 95%CI=1.228-4.413) than those with BLL <1.95 µg/dL.
    Conclusions: High lead level can increase the risk of respiratory infections in preschool children.

    Abstract Increasing evidence shows that human exposure to bisphenols can increase the risk of allergic disease, such as child asthma. However, the mechanism by which exposure to bisphenols causes allergic disease is unclear. In addition, the effects of exposure to bisphenols during pregnancy on infantile eczema have been poorly studied. The aim of our study was to investigate the effect of bisphenols (BPA, BPF and BPS) exposure during pregnancy on immune cells in cord blood, and on the occurrence of infantile eczema. 111 mother-child pairs with urine samples from pregnant women and cord blood were recruited from a birth cohort established in February 2019 in Shenyang, China. The levels of urinary bisphenols and Th1-, Th2-, Treg- and Th17-related genes, and cytokines in cord blood, as well as the incidence of infantile eczema at 6 and 12 months follow up were determined. Our results show that BPA, BPF and BPS were detected in 100%, 63.1% and 46.8% of the urine samples, respectively. The median concentration of urine specific gravity adjusted BPA (SG-BPA) was 7.46 ng/mL. High SG-BPA levels during pregnancy was independently associated with increased risk of infantile eczema (adjusted OR = 2.731, 95%CI: 1.064-7.012, P = 0.037). Higher levels of FOXP3 gene in cord blood had a significantly lower risk of developing eczema in infants (adjusted OR=0.430, 95%CI: 0.190-0.972, P = 0.042). However, BPS and BPF levels were not associated with infantile eczema. FOXP3 gene levels in cord blood mediated the relationship between SG-BPA levels during pregnancy and infantile eczema (indirect effect: β = 0.350 [CI:0.011,1.077]). Our findings indicate that high levels of BPA exposure during pregnancy increase the risk of infantile eczema, which may be associated with down-regulation of FOXP3 gene expression in cord blood.

    Abstract Background: Lead exposure all over the world has gradually declined. As fetuses are more prone to lead exposure, even to low levels of lead exposure, it is important to monitor blood lead levels (BLLs) in pregnancy.
    Methods: We obtained data on BLLs in the third trimester of pregnancy from medical records and measured cord BLLs obtained from 121 mother-child pairs in Shenyang, China from September 2019 to February 2020. We also estimated relationships between socio-demographic, lifestyle and dietary factors during pregnancy as well as cord BLLs to identify the source of lead exposure during pregnancy. BLLs was estimated by atomic absorption spectrometry through graphite furnace ionization techniques. The data which obtained by questionnaires during pregnancy included maternal sociodemographic, lifestyle, dietary factors. We have established three multivariate logistic regression models in which the dichotomous BLLs was used as the dependent variable (cord BLLs ≥20 μg/L vs <20 μg/L).
    Results: The median and geometric mean of cord BLLs were 22.90 μg/L, 21.88 μg/L and BLLs in the third trimester of pregnancy were 25.29 μg/L, 24.66 μg/L, respectively. BLLs showed significant correlations between cord and the third trimester of pregnancy (r = 0.277, P = 0.012). Pregnant women who had not been exposed to passive smoking had lower OR (95 %) [0.43(0.19-0.94)] for cord BLLs ≥20 μg/L than pregnant women who had. Intake of docosahexaenoic acid (DHA) during third trimester of pregnancy presented an OR (95 %) [0.23(0.08-0.61)] for cord BLLs ≥20 μg/L. Consuming more whole grains (>3 times/week) and beverage (≥1 times/week) showed an OR (95%CI) for cord BLLs ≥20 μg/L of 0.09(0.02-0.53) and 0.19(0.06-0.69), respectively.
    Conclusion: This study showed the cord BLLs of Chinese are still higher than most developed countries. Passive smoking is a risk factor for cord BLLs ≥20 μg/L and supplement of DHA, whole grains and beverage consumption during pregnancy may act as a beneficial factor against having cord BLLs ≥20 μg/L.
