National Science Review 2024年第07期 226-238页

High-voltage aqueous zinc ion batteries（AZIBs） with a high-safety near-neutral electrolyte is of great significance for practical sustainable application; however, they suffer from anode and electrode/electrolyte interfacial incompatibility. Herein, a conversion-type anode chemistry with a low anodic potential, which is guided by the Gibbs free energy change of conversion reaction, was designed for high-voltage near-neutral AZIBs. A reversible conversion reaction between ZnC2O4·2H2O particles and three-dimensional Zn metal networks well-matched in CH3COOLi-based electrolyte was revealed. This mechanism can be universally validated in the battery systems with sodium or iodine ions. More importantly, a cathodic crowded micellar electrolyte with a water confinement effect was proposed in which lies the core for the stability and reversibility of the cathode under an operating platform voltage beyond 2.0 V, obtaining a capacity retention of 95% after 100 cycles. Remarkably, the scientific and technological challenges from the coin cell to Ah-scale battery, sluggish kinetics of the solid-solid electrode reaction, capacity excitation under high loading of active material, and preparation complexities associated with large-area quasi-solid electrolytes,were explored, successfully achieving an 88% capacity retention under high loading of more than 20 mg cm-2and particularly a practical 1.1 Ah-level pouch cell. This work provides a path for designing low-cost, eco-friendly and high-voltage aqueous batteries.

肿瘤电场治疗是一种新的治疗恶性实体肿瘤的疗法,多采用电场仿真分析不同参数的肿瘤电场治疗在瘤体上产生的电场分布。但目前,由于仿真模型构建技术路线较难复现或实现成本较高,因此本研究采用常用的软件工具建立了易实现的高精度肿瘤电场治疗有限元仿真模型,模型精度在1 mm^(3)水平。本研究利用该仿真模型开展了不同组织电学参数、电极配置等因素分析,研究结果显示,对肿瘤内电场分布存在影响的因素包括:头皮、头骨电导率的变化(瘤体治疗场最高变化21.0%)、肿瘤电导率的变化(瘤体治疗场最高变化157.8%)和不同的电极位置及组合(瘤体治疗场最高变化74.2%)。综上,本文研究结果验证了所提建模方法的可行性与有效性,或可为今后的肿瘤电场治疗仿真分析和临床应用提供重要参考。

OBJECTIVE： To explore the characteristics of prima- ry liver cancer in terms of Traditional Chinese Medi-cine （TCM） by analyzing the variations of the patterns along with the clinical stages. METHODS： The patients who were hospitalized in the Changhai Hospital of Traditional Chinese Medi- cine dated from March 1999 to December 2008 were included in this retrospective study. The patients were grouped according to their cancer stag- es, and their patterns were judged and quantified according to the ＂Standard diagnosis and quantitative criteria of the common patterns in primary liv-er cancer＂ formulated by the Changhai Hospital of Traditional Chinese Medicine. Statistics methods included ANOVA and nonparametric test, among ***： The data of the 398 newly diagnosed patients showed that Qi Stagnation, Blood Stasis, and Dampness patterns were more frequent than the other basic patterns with relatively high scores; patterns of Liver Qi Stagnation, Liver Blood Stasis, and Dampness Heat were more than the other complex patterns and scored relatively high. Scores of Dampness and Liver Qi Stagnation patterns varied among the groups at different stages and the differences were statistically significant （PDampeness= 0.002, PLiver Qi Stagnation ： 0.020）. The highest scores of Damp- ness pattern and Liver Qi Stagnation pattern corresponded with Stage Ⅲ b, and Stage Ⅲ a, respectively. Dampness pattern frequency was higher （P = 0.001） in the Stage Ⅲb group than in other ***： Pattern characteristics in patients with primary liver cancer of different clinical stages might manifest in the variations of the Dampness pattern along the process of the disease and the major pathogenic factor of primary liver cancer might be Dampness.

ThERF1 regulates its target genes via binding to a novel cis-acting element in response to salt stress

引用

Journal of Integrative Plant Biology 2015年第10期57卷 838-847页

作者： Liuqiang Wang Chao Wang liping qin Wenjin Liu Yucheng Wang Key Laboratory of Biogeography and Bioresource in Arid Land Xinjiang Institute of Ecology and Geography Chinese Academy of Sciences State Key Laboratory of Tree Genetics and Breeding (Northeast Forestry University)

Ethylene responsive factors (ERFs) are plant-specific transcription factors that are involved in a variety of biological processes. We previously demonstrated that an ERF gene from Tamarix hispida, ThERF1, encodes a protein binding to GCC-box and DRE motifs and negatively modulates abiotic stress tolerance. In the present study, microarray analysis was performed to study the genes regulated by ThERF1 on a genomic scale. There were 154 and 307 genes (respectively representing 134 and 260 unique genes) significantly up- and downregulated by ThERF1 under salt stress conditions, respectively. A novel motif, named TTG, was identified to be recognized by ThERF1, which commonly presents in the promoters of ThERF1-targeted genes. The TTG motif is also bound by other ERFs of a different subfamily from T. hispida and Arabidopsis, indicating that it is commonly recognized by ERF proteins. The binding affinities of ERFs to the TTG motif are significantly induced by salt stress. The TTG motif is more enriched than the GCC-box and DRE motifs in the promoters of ThERF1-targeted genes. Taken together, these studies suggested that the TTG motif plays an important role in the gene expression regulated by ERFs in response to salt stress.

ThERF1 from Tamarix hispida confers decreased tolerance to oxidative and drought stresses and is regulated by a WRKY protein

引用

Journal of Forestry Research 2016年第4期27卷 767-772页

作者： Liuqiang Wang Chao Wang liping qin Ping Hu Yucheng Wang State Key Laboratory of Tree Genetics and Breeding(Northeast Forestry University) Harbin 150040 China Key Laboratory of Biogeography and Bioresource in Arid Land Xinjiang Institute of Ecology and Geography Chinese Academy of Sciences Urumqi 8300ll China

The ethylene-responsive factor family is one of the largest families of plant-specific transcription factors that are involved in plant development and stress responses. Previously, we demonstrated that the gene Th ERF1,encoding a novel ethylene-responsive factor from Tamarix hispida, negatively modulates abiotic stress tolerance. In the present study, Arabidopsis plants overexpressing Th ERF1 had decreased oxidative tolerance and increased transpirational water loss rate compared with wild-type plants, leading to sensitivity to abiotic stress. Real-time RT-PCR showed that the upstream regulator of Th ERF1,Th WRKY2, is involved in responses to different abiotic stresses. Furthermore, both Th WRKY2 and Th ERF1 shared similar expression patterns in the stems and leaves of *** when exposed to salinity, drought and abscisic acid. Chromatin immunoprecipitation assays further confirmed that Th WRKY2 can directly bind to the promoter of Th ERF1 and regulate its expression. This study revealed the regulatory mechanism of Th ERF1 expression in response to abiotic stresses in T. hispida.

2020年区域全面经济伙伴关系协定(RCEP)的签署标志着世界上最具贸易发展潜力的自由贸易区的成立。日韩两国是我国主要的农业贸易出口国,随着贸易壁垒的进一步下降,中日韩三国农产品贸易规模是否进一步扩大值得我们深入研究。本文构建随机前沿贸易引力模型,对日韩实施的绿色贸易壁垒对中国农产品出口两国的影响进行了实证分析,研究表明:绿色贸易壁垒确实抑制了中国农产品出口日韩的贸易规模。本文就如何解决绿色贸易壁垒问题也提出了相应的政策建议。
