Chinese Medical Journal 2016年第24期129卷 2958-2966页

作者： Miao-Xin Peng xiao-yue wang Fan wang Lei wang Pei-Pei Xu Bing Chen Department of Hematology The Affiliated Drum Tower Hospital of Nanjing University Medical School Nanjing Jiangsu 210008 China Department of Laboratory The Affiliated Drum Tower Hospital of Nanjing University Medical School Nanjing Jiangsu 210008 China Department of Hematology Zhongda Hospital Medical School Southeast University Nanjing Jiangsu 210009 China

Background： Traditional Chinese medicine wogonin plays an important role in the treatment of leukemia. Recently, the application of drug-coated magnetic nanoparticles （MNPs） to increase water solubility of the drug and to enhance its chemotherapeutic efficiency has attracted much attention. Drugs coated with MNPs are becoming a promising way for better leukemia treatment. This study aimed to assess the possible molecular mechanisms of wogonin-coated MNP-Fe3O4 （Wog-MNPs-Fe3O4） as an antileukemia agent. Methods： After incubated for 48 h, the antiproliferative effects of MNPs, wogonin, or Wog-MNPs-Fe3O4on K562/A02 cells were determined by methyl thiazolyl tetrazolium （MTT） assay. The apoptotic rates of K562/A02 cells treated with either wogonin or Wog-MNPs-Fe3O4were determined by flow cytometer （FCM） assay. The cell cycle arrest in K562/A02 cells was determined by FCM assay. The elementary molecular mechanisms of these phenomena were explored by Western blot and reverse transcriptase polymerase chain reaction （RT-PCR）. Results： With cell viabilities ranging from 98.76% to 101.43%, MNP-Fe3O4was nontoxic to the cell line. Meanwhile, the wogonin and Wog-MNPs-Fe3O4had little effects on normal human embryonic lung fibroblast cells. The cell viabilities of the Wog-MNPs-Fe3O4group （28.64–68.36%） were significantly lower than those of the wogonin group （35.53–97.28%） in a dose-dependent manner in 48 h （P 〈 0.001）. The apoptotic rate of K562/A02 cells was significantly improved in 50 μmol/L Wog-MNPs-Fe3O4group （34.28%） compared with that in 50 μmol/L wogonin group （23.46%; P〈 0.001）. Compared with those of the 25 and 50 μmol/L wogonin groups, the ratios of G0/G1-phase K562/A02 cells were significantly higher in the 25 and 50 μmol/L Wog-MNPs-Fe3O4groups （all P〈 0.001）. The mRNA and protein expression levels of the p21 and p27 in the K562/A02 cells were also significantly higher in the Wog-MNPs-Fe3O4group compared with those of the wogonin group （all P〈 0.001）. Conclusions： This

ITS2,a Better DNA Barcode than ITS in Identification of Species in Artemisia L.

引用

Chinese Herbal Medicines 2016年第4期8卷 352-358页

作者： xiao-yue wang Si-hao Zheng Yang Liu Jian-ping Han Institute of Medicinal Plant Development Chinese Academy of Medicinal Sciences & Peking Union Medicinal College

Objective To select a more suitable DNA barcode to identify the species in Artemisia L. Methods ITS, ITS2, and three other major universal barcode candidates（mat K, rbc L, and psb A-trn H） were evaluated in the identification efficiency using a total of 1433 sequences downloaded from Gen Bank representing 343 species in Artemisia L. ITS and ITS2 were evaluated in the PCR and sequencing rate, sequencing peak quality（Q value）, and misread rate. One hundred and twelve A. annua samples were collected from 11 populations across over China, which were amplified with universal primers on the ITS and ITS2 regions. Results ITS and ITS2 shared a higher identification efficiency and exhibited 71.43% and 64.11% detectability at the species level, respectively. The Q values of ITS and ITS2 showed that the direct PCR sequencing data were reliable for the ITS2 region and ITS exhibited poor sequencing trace quality. In certain sites, the ITS sequences exhibited reading ambiguities and errors, indicating that the misread and deletion sites in the ITS region would incorrectly inflate the identification ratio. Conclusion ITS2 is a suitable barcode for identification of species in Artemisia L., which enlarges the optimal range of divergence levels for taxonomic inferences using ITS2 sequences.

Chinese Herbal Medicines 2017年第3期9卷 218-225页

作者： Zi-tong Gao Li-li wang xiao-yue wang Yang Liu Jian-ping Han Institute of Medicinal Plant Development Chinese Academy of Medical Sciences & Peking Union Medical College

Objective Using authentic raw herbal materials is fundamental to herbal medicine quality. Cuscuta chinensis and C. australis are two important species of Cuscutae Semen recorded in Chinese Pharmacopoeia. Due to having tiny bodies of seeds, it is extremely difficult to differentiate them from adulterants and closely related species by morphologic characteristics, leading to serious safety problems. Methods In this study, we developed a fast and efficient method to identify Cuscutae Semen on the market. First, a total of 207 ITS2 sequences representing 45 related species of Cuscutae Semen were collected to construct a standard DNA barcode database, then 33 commercial samples purchased from markets were analyzed by BLAST, and Neighbor-joining tree was used to verify the efficacy of the database. Results The percentage of counterfeits and adulterants in the 33 commercial samples were up to 69.7%, and only 10 commercial products were found to be genuine. The adulterated species included 11 species （Amaranthus hybridus, Brassica carinata, Brassica juncea var. megarrhiza, Chenopodium album, Corispermum heptapotamicum, Cuscuta alata, Cuscuta japonica, Cuscuta monogyna, Foeniculum vulgare, Glycine max, and Medicago sativa）. Conclusion DNA barcoding is a fast and efficient method to identify Cuscutae Semen on the market.

Unlocking the stable interface in aqueous zinc-ion battery with multifunctional xylose-based electrolyte additives

Journal of Energy Chemistry 2025年第1期100卷 770-778页

作者： xiaoqin Li Jian Xiang Lu Qiu xiaohan Chen Yinkun Zhao Yujue wang Qu yue Taotao Gao Wenlong Liu Dan xiao Zhaoyu Jin Panpan Li Institute for Advanced Study Chengdu University School of Mechanical Engineering Chengdu University College of Food and Biological Engineering Chengdu University Institute of Fundamental and Frontier Sciences University of Electronic Science and Technology of China College of Materials Science and Engineering Sichuan University

The growth of dendrites and the side reactions occurring at the Zn anode pose significant challenges to the commercialization of aqueous Zn-ion batteries（AZIBs）. These challenges arise from the inherent conflict between mass transfer and electrochemical kinetics. In this study, we propose the use of a multifunctional electrolyte additive based on the xylose（Xylo） molecule to address these issues by modulating the solvation structure and electrode/electrolyte interface, thereby stabilizing the Zn anode. The introduction of the additive alters the solvation structure, creating steric hindrance that impedes charge transfer and then reduces electrochemical kinetics. Furthermore, in-situ analyses demonstrate that the reconstructed electrode/electrolyte interface facilitates stable and rapid Zn2+ion migration and suppresses corrosion and hydrogen evolution reactions. As a result, symmetric cells incorporating the Xylo additive exhibit significantly enhanced reversibility during the Zn plating/stripping process, with an impressively long lifespan of up to 1986 h, compared to cells using pure ZnSO4electrolyte. When combined with a polyaniline cathode, the full cells demonstrate improved capacity and long-term cyclic stability. This work offers an effective direction for improving the stability of Zn anode via electrolyte design, as well as highperformance AZIBs.

Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.
