Article

The chemical constituents in the ethanol extract of Viburnum utile were isolated by column chromatography with D101 macroporous resin, silica gel, and Sephadex LH-20. Their structures were identified by spectroscopic techniques such as NMR and MS. All the compounds were evaluated for the inhibitory activities against α-glucosidase. Sixteen compounds were obtained and identified as viburnumide A(1), vitamin E(2), α-amyrin(3), α-tocoquinone(4), narjatamanin B(5), ethyl caffeate(6), naringenin(7), apigenin(8), ethyl β-D-ribo-hex-3-ulopyranoside(9), trans-p-hydroxycinnamic acid(10), amentoflavone(11), apigenin-7-O-β-D-glucoside(12), luteolin-7-O-β-D-glucoside(13), henryoside(14), ursolic acid(15), and 2α-hydroxy-oleanolic acid(16). Among them, compound 1 was a new compound, and compounds 2-16 were isolated from V. utile for the first time. The inhibitory activity(IC_(50) of 4.0 μmol·L~(-1)) of compound 11 against α-glucosidase was comparable to that of the positive control acarbose(IC_(50) of 2.3 μmol·L~(-1)).

BACKGROUNDEvidence suggested that abiotic airborne exposures may be associated with changes in body composition. However, more evidence is needed to identify key pollutants linked to adverse health effects and their underlying biomolecular mechanisms, particularly in sensitive older adults.OBJECTIVESOur research aimed to systematically assess the relationship between abiotic airborne exposures and changes in body composition among healthy older adults, as well as the potential mediating mechanisms through the serum lipidome.METHODSFrom September 2018 to January 2019, we conducted a monthly survey among 76 healthy adults (60-69 years old) in the China Biomarkers of Air Pollutant Exposure (BAPE) study, measuring their personal exposures to 632 abiotic airborne pollutions using MicroPEM and the Fresh Air wristband, 18 body composition indicators from the InBody 770 device, and lipidomics from venous blood samples. We used an exposome-wide association study (ExWAS) and deletion/substitution/addition (DSA) model to unravel complex associations between exposure to contaminant mixtures and body composition, a Bayesian kernel machine regression (BKMR) model to assess the overall effect of key exposures on body composition, and mediation analysis to identify lipid intermediators.RESULTSThe ExWAS and DSA model identified that 2,4,5-T methyl ester (2,4,5-TME), 9,10-Anthracenedione (ATQ), 4b,8-dimethyl-2-isopropylphenanthrene, and 4b,5,6,7,8,8a,9,10-octahydro-(DMIP) were associated with increased body fat mass (BFM), fat mass indicators (FMI), percent body fat (PBF), and visceral fat area (VFA) in healthy older adults [Bonferroni-Hochberg false discovery rate __-mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"-__(FDRBH)<0.05]. The BKMR model demonstrated a positive correlation between contaminants (anthracene, ATQ, copaene, di-epi-__-mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"-__α-cedrene, and DMIP) with VFA. Mediation analysis revealed that phosphatidylcholine [PC, PC(16:1e/18:1), PC(16:2e/18:0)] and sphingolipid [SM, SM(d18:2/24:1)] mediated a significant portion, ranging from 12.27% to 26.03% (p-value __-mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"-__<0.05), of the observed increase in VFA.DISCUSSIONBased on the evidence from multiple model results, ATQ and DMIP were statistically significantly associated with the increased VFA levels of healthy older adults, potentially regulated through lipid intermediators. These findings may have important implications for identifying potentially harmful environmental chemicals and developing targeted strategies for the control and prevention of chronic diseases in the future, particularly as the global population is rapidly aging. https://doi.org/10.1289/EHP13865.

[Characteristics, Sources Apportionment, and Health Risks of PM_2.5-bound PAHs and Their Derivatives Before and After Heating in Zibo City].

Article

作者: Gao, Yu-Zong ; Xu, Bo ; Zhao, Xue-Yan ; Wu, Li-Ping ; Ji, Ya-Qin ; Sun, Gang-Li ; Yang, Wen

Atmospheric polycyclic aromatic hydrocarbons (PAHs) and their derivatives are a global problem that influences the environment and threatens human health. To investigate the characteristics, sources, and health risk assessment of PM_2.5-bound PAHs and their derivatives, PM_2.5 were collected at an urban site in Zibo from November 5 to December 26, 2020, and the concentrations of 16 conventional PAHs, nine NPAHs, and five OPAHs in PM_2.5 were analyzed using gas chromatography-mass spectrometry. Source apportionment of PAHs and their derivatives was conducted using diagnostic ratios and a PMF model, and the health risks of PAHs and their derivatives to adult men and women were evaluated using the source-dependent incremental lifetime cancer risk (ILCR) model. The results showed that the average concentrations of ∑₁₆pPAHs, ∑₉NPAHs, and ∑₅OPAHs in PM_2.5 of Zibo City during the sampling period were (41.61 ± 13.40), (6.38 ± 5.70), and (53.20 ± 53.47) ng·m^-3, respectively. The concentrations of the three PAHs increased significantly after heating, which were 1.31, 2.04, and 5.24 times larger than those before heating. During the sampling period, Chr, BaP, and BaA were the dominant components of pPAHs; 9N-Ant and 2N-Flt + 3N-Flt were the dominant components of NPAHs; and ATQ and BZO were the dominant components of OPAHs. Source apportionment results showed that motor vehicles were the main source of PAHs and their derivatives in PM_2.5 before heating, whereas after heating, the main sources were the mixed source of coal and biomass combustion and secondary formation. The total BaP equivalent (TEQ) was 14.5 ng·m^-3 during the sampling period, and the TEQ increased significantly after heating, which was approximately 1.2 times of that before heating. Assisted by the individual PAH source apportionment results, the ILCR of PM_2.5-boundPAHs and NPAHs in Zibo City had a certain potential carcinogenic risk for adult males (1.06 × 10^-5) and females (9.32 × 10^-6). Among them, the health risks of PAHs from gasoline vehicles, diesel vehicles, and coal/biomass combustion were significantly higher than those from other emission sources.
