Background: The protective role of (poly)phenols against metabolic disorders has been extensively studied in adults but not in ***: To assess associations of dietary (poly)phenols and their subclasses with cardiometabolic health parameters in adolescents. Methods: A cross-sectional study was conducted in 944 individuals aged 11 to 14 years enrolled in the SI! Program for Secondary Schools trial (nCT03504059). (Poly)phenol intake was assessed using semi-quantitative food frequency questionnaires and the Phenol-Explorer database. The measured cardiometabolic parameters were waist circumference (WC) age-sex z-score， blood pressure (BP) age-sex z-score， blood glucose (BG)， triglycerides (TG)， and high-density lipoprotein cholesterol (HDL-c). Multilevel mixed-effect linear regression models were applied to examine the association between (poly)phenol quintiles and cardiometabolic health ***: Compared to the lowest quintile， adolescents in the highest quintile of total (poly)phenol intake had lower WC z-scores (β=-0.09， 95%CI=-0.09;-0.08， P-for trend=0.002)， mean arterial pressure z-scores (β =-0.11， 95%CI=-0.12;-0.09， P-for trend=0.206)， and HDL-c (β=-1.52， 95%CI=-2.90;-0.14， P-for trend=0.108)， after multivariable adjustment. The WC z-scores (β=-0.11， 95%CI=-0.19;-0.03， P-for trend=0.013) and HDL-c (β=-2.16， 95%CI=-3.78;-0.53， P-for trend=0.046) were lower in the highest quintile of flavonoid intake compared to the lowest quintile. The highest quintile of phenolic acid intake was associated with a lower WC z-score (β=-0.14， 95%CI=-0.26;-0.02， P-for trend=0.011) and TG levels (β=-8.83， 95%CI=-12.37;-5.30， P-for trend nd the highest quintile of stilbene intake with lower BG (β=-1.83， 95%CI= -3.103;-0.64， P-for trend nd TG (β=-3.22， 95%CI= -4.95;-1.49， P-for trend=0.034)， and with higher HDL-c (β=2.328， 95%CI= 1.40;3.17， P-for trend=0.466) compared to the lowest quintile.

Understanding the structural changes and degradation mechanisms of organic pollutants is critical in environmental *** this work, a xenon lamp was used as an analog light source to simulate the eff ect of sunlight on 3,3′-diamino-4,4′-azoxyfurazan (DAAF) in aqueous solution. Combining high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC–MS/MS), surface-enhanced Raman spectroscopy (SERS) with density functional theory (DFT), the degradation intermediates and mechanisms of DAAF were investigated. The sequential breakdown of the–nH 2and–O–n=bonds, followed by the removal of atomic O from–n=n(O)–, was emphasized and investigated using two-dimensional correlation spectroscopy (2D-cos) and SERS spectra. Three intermediates with mass-to-charge ratios (m/z) 181, 251 and180 were identifi ed and characterized by integrating experimental SERS data with DFT-calculated Raman spectra based on structures hypothesized from MS spectra. The fi ndings from HPLC–MS and SERS not only corroborate each other but also provide a foundation for a detailed examination of the DAAF degradation process.

壳寡糖是良好的免疫增强剂，但在水生动物中的应用还十分有限。本研究通过间隔投喂的方式研究壳寡糖对仿刺参生长性能、非特异性免疫能力、消化能力、组织学和抗病力的影响。实验挑选体重(18.51±0.28) g的仿刺参，对照组饲喂基础饲料，实验组以3天1次的饲喂频率饲喂含0.5%壳寡糖的饲料，其余时间饲喂基础饲料，连续投喂8周后，检测该饲喂方式下仿刺参生长性能、非特异性免疫能力、肠道消化酶、肠道和呼吸树组织学、肠道免疫基因表达情况以及对灿烂弧菌的抗病力。结果显示，3天1次的壳寡糖饲喂频率极显著提高了仿刺参的脏壁比和肠壁比；在免疫指标方面，显著提高了仿刺参体腔细胞的吞噬活性和呼吸爆发能力，极显著提高了肠道的酸性磷酸酶(ACP)、碱性磷酸酶(AKP)、溶菌酶(LZM)和总一氧化氮合酶(T-nOS)活性，其中肠道AKP和LZM活性分别提高了70.06%和156%，肠道Aj-lyz基因表达量极显著提高了22.04%；抗氧化指标结果显示，实验组极显著提高了仿刺参体腔细胞过氧化氢酶(CAT)活性，而体腔细胞和肠道的丙二醛(MDA)含量无显著差异。组织学结果显示，该饲喂频率极显著提高了仿刺参前肠肌肉层厚度和浆膜层厚度，中肠和后肠的皱襞高度和宽度。灿烂弧菌攻毒结果表明，实验组仿刺参的相对保护率达到66.67%。研究表明，3天1次的饲喂频率能够一定程度上提高仿刺参的生长性能，非特异性免疫酶、消化酶活性，并明显改善肠道结构。研究结果可为壳寡糖对仿刺参作用机制的研究及投喂频率的确定提供数据支撑和理论依据。

作者： Rong Min WAnG Jing Feng SOnG Yu Feng HE juan juan MAO Yan LI Key Laboratory of Polymer Materials of Gansu Province Institute of Polymer Northwest Normal University Lanzhou 730070

The interaction between chitooligosaccharide-5-fluorouracil （cos-5FU） and bovine serum albumin （BSA） was studied by fluorescence spectroscopy. It was found that an energy transfer between cos-5FU and BSA had been occurred. The binding constants were calculated, k298K=1.175×10^4 L·mol^-1. Based on the mechanism of energy transfer of dipole-dipole interaction between the donor and acceptor, the distance between BSA and cos-SFU was determined.
