3Intercropping with Solanum nigrum and Solanum photeinocarpum from Two Ecoclimatic Regions Promotes Growth and Reduces Cadmium Uptake of Eggplant Seedlings显示文摘Soil contamination by heavy metals is a serious environmental problem worldwide, and reduction of heavy metal accumulation in vegetables grown on contaminated land is a matter of urgency. A pot experiment was conducted to study the effects of intercropping with the Cd hyperaccumulators Solanum nigrum and Solanum photeinocarpum from two ecoclimatic regions, Ya'an and Chengdu,Sichuan Province, China, on the growth and cadmium(Cd) uptake of eggplant(Solanum melongena L.). The biomass, photosynthetic pigment contents, and activities of antioxidant enzymes of eggplant were enhanced by intercropping. The biomass of eggplant was the highest after intercropping with S. photeinocarpum from Ya'an, but did not differ significantly from that after intercropping with S. nigrum from Chengdu. The shoot Cd content of eggplant was significantly reduced by intercropping with the hyperaccumulators,which ranked as follows: S. nigrum from Chengdu > S. nigrum from Ya'an > S. photeinocarpum from Chengdu > S. photeinocarpum from Ya'an, with the decreases being 19.60%, 14.36%, 9.66%, and 6.42%, respectively, as compared with the control. The lowest shoot Cd content and translocation factor of eggplant were attained after intercropping with S. nigrum from Chengdu. Therefore, it was feasible to intercrop eggplant with S. nigrum and S. photeinocarpum on Cd-contaminated soil.TANG Yi HE Juan YU Xuena XIE Yongdong LIN Lijin SUN Guochao LI Huanxiu LIAO Mingan LIANG Dong XIA Hui WANG Xun ZHANG Jing LIU Zejing TU Lihua LIU Li 2017Pedosphere2017,27,3:17
4An individualized immune signature of pretreatment biopsies predicts pathological complete response to neoadjuvant chemoradiotherapy and outcomes in patients with esophageal squamous cell carcinoma显示文摘No clinically available biomarkers can predict pathological complete response(pCR)for esophageal squamous cell carcinomas(ESCCs)with neoadjuvant chemoradiotherapy(nCRT).Considering that antitumor immunity status is an important determinant for nCRT,we performed an integrative analysis of immune-related gene profiles from pretreatment biopsies and constructed the first individualized immune signature for pCR and outcome prediction of ESCCs through a multicenter analysis.During the discovery phase,14 differentially expressed immune-related genes(DEIGs)with greater than a twofold change between pCRs and less than pCRs(Chaoqi Zhang Guochao Zhang Nan Sun Zhen Zhang Liyan Xue Zhihui Zhang Haijun Yang Yuejun Luo Xiaoli Zheng Yonglei Zhang Yufen Yuan Ruixue Lei Zhaoyang Yang Bo Zheng Le Wang Yun Che Feng Wang Sihui Wang Shugeng Gao Qi Xue Yi Zhang Jie He 2020Signal Transduction and Targeted Therapy2020,5,1:7
5Single-zircon dating of Precambrian strata in the west sector of the northern Qilian Mountains and its geological significance显示文摘Single_zircon evaporation method was employed in the present study to determine the age of the iron_bearing rock series in Precambrian strata in the western sector of the northern Qilian Mountains. Three zircon ages from the diabase of the Aoyougou ophiolite previously put into Upper Lithologic Formation of the Zhulongguan Group are (1 840±2), (1 783±2) and (1 784±2) Ma respectively, whereas the zircon ages from the welded breccias in the Zhulongguan Group are (733±7), (738±4) and (604±6) Ma respectively. These results show that they should belong to the bottom of the middle Proterozoic and the upper part of upper Proterozoic respectively.Jingwen Mao Zhaochong Zhang Jianmin Yang Biao Song Maobing Wu Guochao Zuo 1998Chinese Science Bulletin1998,43,15:5
6Personalized neoantigen pulsed dendritic cell vaccine for advanced lung cancer显示文摘Neoantigens are considered to be ultimate target of tumor immunotherapy due to their high tumor specificity and immunogenicity.Dendritic cell(DCs)vaccines based on neoantigens have exciting effects in treatment of some malignant tumors and are a promising therapeutic modality.Lung cancer is a lethal disease with the highest morbidity and mortality rate in the world.Despite the rapid development of targeted therapy and immune checkpoint inhibitors for lung cancer in recent years,their efficacy is still unsatisfactory overall.Therefore,there is an urgent unmet clinical need for lung cancer treatment.Here,we attempted to treat lung cancer using a personalized neoantigen peptide-pulsed autologous DC vaccine and conducted a single-arm,2 medical centers,pilot study initiated by the investigator(ChiCTR-ONC 16009100,NCT02956551).The patients enrolled were patients with heavily treated metastatic lung cancer.Candidate neoantigens were derived from whole-exome sequencing and RNA sequencing of fresh biopsy tissues as well as bioinformatics analysis.A total of 12 patients were enrolled in this study.A total of 85 vaccine treatments were administered with a median value of 5 doses/person(range:3-14 doses/person).In total,12-30 peptide-based neoantigens were selected for each patient.AIl treatment-related adverse events were grade 1-2 and there were no delays in dosing due to toxic effects.The objective effectiveness rate was 25%;the disease control rate was 75%;the median progression-free survival was 5.5 months and the median overall survival was 7.9 months.This study provides new evidence for neoantigen vaccine therapy and new therapeutic opportunities for lung cancer treatment.Zhenyu Ding Qing Li Rui Zhang Li Xie Yang shu Song Gao Peipei Wang Xiaoqing Su Yun Qin Yuelan Wang Juemin Fang Zhongzheng Zhu Xuyang Xia Guochao Wei Hui Wang Hong Qian Xianling Guo Zhibo Gao Yu Wang Yuquan Wei Qing Xu Heng Xu Li Yang 2021Signal Transduction and Targeted Therapy2021,6,2:3

8Detection of UXO magnetic anomaly in Jinshan area显示文摘Magnetic survey is one of the most successful techniques for locating buried unexploded ordnances( UXO). For the location and identification of buried UXO in Jinshan area,a total-field magnetic survey is applied. The analytic signal of magnetic field is widely used to outline the boundaries of geology bodies,slightly dependent on the magnetization direction. In order to locate the UXO position,the analytic signal is applied to process the magnetic UXO data,which performs better than the conventional magnetic data. Then a typical UXO anomaly is extracted from the original data to invert for its depth by an improved Euler method proposed.The calculated depth is close to the real buried depth.WU Guochao HUANG Danian ZHANG Chong YUAN Yuan 2015Global Geology2015,18,1:2
9Temporo-Spatial Distribution and Evolution of Ore Deposits in the West Sector of the Northern Qilian Mountains显示文摘The west sector of the northern Qilian Mountains is well-known for the Jingtieshan-type iron deposits. A new breakthrough has been made in prospecting for gold and copper in recent years. In this paper, the distribution characteristics of ore deposits in the study area are discussed from the viewpoint of tectonic evolution. It is suggested that there are 9 stages of mineralization from the Palaeoproterozoic to Indosinian. Four minerogenetic series and two minerogenetic subseries of ore deposits are recognized. Iron mineralization occurred in several stages, while most of the metals were accumulated in large amounts in the Caledonian. The enrichment and mineralization of gold is related to large-scale shear-strike-slip faults and the ascent and unloading of deep-seated fluids.MAO Jingwen ZHANG Xiaoyu ZHANG Zhaochong REN Fengshou ZUO Guochao ZHANG Zuoheng YANG Jianmin WANG Zhiliang YE Dejin 1999Acta Geologica Sinica(English Edition)1999,73,2:1

12Late Triassic Magma Mixing and Fractional Crystallization in the Qingchengzi Orefield,Eastern Liaoning Province:Regional Petrogenetic and Metallogenic Implications显示文摘The Qingchengzi orefield is an important Pb-Zn-Au-Ag polymetallic orefield in NE Chi-na.The Indosinian magmatism has formed the Shuangdinggou batholith and the Xinling stock,as well as dikes of quartz monzonite porphyry and lamprophyre.According to petrographic characteristics,the Shuangdinggou intrusion can be divided into the main suite and the central suite.Zircon U-Pb dat-ing yielded crystallization ages of 215.0-220.9 Ma for these various Qingchengzi magmatic units,which are within analytical error and represent coeval magmatism.The Shuangdinggou main suite contains abundant mafic microgranular enclaves(MMEs)and shows features of magma mixing.Geochemically,the major oxide contents of the MMEs and their quartz monzonite host show well-defined linear frac-tionation trends.The REE and trace element patterns of the MMEs and their host are similar,which demonstrates certain degree of geochemical homogenization between the two during magma mixing.The Shuangdinggou main suite shares similar geochemical characteristics with typical high Ba-Sr gra-nites(Ba=1082 ppm-2051 ppm,Sr=803 ppm-886 ppm),and was likely originated from the mixing between a melt derived from partial melting of the thickened lower crust and the enriched mantle.The central suite was likely formed by fractional crystallization of the main-suite magma.The Xinling in-trusion may represent a branch of the Shuangdinggou intrusion and has the same genesis as the central suite.The quartz monzonite porphyries geochemically mimic the Shuangdinggou main suite,and may also be an epioic facies of the Shuangdinggou intrusion.The MMEs and lamprophyres may have been derived from incomplete magma mixing.Formation of the Pb-Zn and Au-Ag deposits in the Qing-chengzi orefield may have been related to the granite/quartz monzonite porphyries near the Shuangdinggou intrusion,which were formed by magma mixing and fractional crystallization.Hongjing Xie Yuwang Wang Dedong Li Guochao Zhou Zhichao Zhang 2021Journal of Earth Science2021,32,1:1

14Screening of High Virulent Isolate of Beauveria spp. against Helicoverpa assulta and Changes in Protective Enzymes Activities of Infected Larvae显示文摘Eleven isolates of Beauveria spp., including B. bassiana(Bb062) newly isolated from Helicoverpa assulta, and other seven B. bassiana isolates and three B. brongniartii isolates that were originally isolated from different geographic origins and various hosts, were tested against the 3^(rd) instar larvae of H. assulta. The protective enzyme activity in the 3^(rd) larvae of H. assulta infected by highly virulent isolate was also assayed. The results showed that the isolate Bb062 had the highest virulence to the 3^(rd) instar larvae among eleven isolates of Beauveria spp., with a corrected mortality reaching 91.07% within 10 d post treatment, and the LT_(50) was 4.67 d. After inoculated with three concentrations(1.0 ×10~6, 1.0 ×10~7 and 1.0×10~8 conidia/mL) of Bb062 conidial suspension, the accumulative mortality of H. assulta larvae increased with the increase of concentration and observation time, and the LC_(50) was 1.82×10~7 conidia/mL. Activities of superoxide dismutase(SOD), peroxidase(POD) and catalase(CAT) in H. assulta larvae first increased rapidly then dropped sharply within 72 h. Bb062 showed high virulence to H. assulta and could inhibit activities of protective enzymes. Therefore, it will be a promising biocontrol agent against H. assulta.Zhang Guochao Liu Mingke Zhou Jianyun Chen Dexin Yan Fangfang Xu Chuangtao Jiang Lianqiang Li Maoye 2019Plant Diseases and Pests2019,10,2:0
15Research on the Applications of Big Data on Artistic Designing and Its Infl uences on the Design Behavior显示文摘In this paper, we conduct research on the applications of big data on artistic designing and its infl uences on the design behavior. Modern art design enhance the grade of the product, increase the added value of products, promote the development of the economy, make the product of the aesthetic value and economic value of the perfect unity. In today’s society due to the value of the product are much more than the product itself contains the value of performance, usage, etc. is more of a product in gradually improve the aesthetic value, sometimes even more than the use of the product value and exchange value, therefore the product has become the dominant value. Under this basis, we propose the new idea on the design pattern that will be meaningful.Guochao Zhang 2016International Journal of Technology Management2016,,6:0
16Simultaneous capture of ISG15 conjugating and deconjugating enzymes using a semi-synthetic ISG15-Dha probe显示文摘ISG15 is a ubiquitin-like(Ubl) protein attached to substrate proteins by ISG15 conjugating enzymes whose dysregulation is implicated in a multitude of disease processes, but the probing of these enzymes remains to be accomplished. Here, we describe the development of a new activity-based probe ISG15-Dha(dehydroalanine) through protein semi-synthesis. In vitro crosslinking and cell lysate proteomic profiling experiments showed that this probe can sequentially capture ISG15 conjugating enzymes including E1 enzyme UBA7, E2 enzyme UBE2L6, E3 enzyme HERC5, the previously known ISG15 deconjugating enzyme(USP18), as well as some other enzymes(USP5 and USP14) which we additionally confirmed to impart deISGylation activity. Collectively, ISG15-Dha provides a new tool that can simultaneously capture ISG15 conjugating and deconjugating enzymes for biochemical or pharmacological studies.Chuntong Li Tian Wang Lujun Liang Guochao Chu Jiachen Zhang Wei He Lei Liu Jinghong Li 2023Science China Chemistry2023,66,3:0
17诱导性多能干细胞的低基因组稳定性使非同源末端连接增加显示文摘背景与目的诱导性多能干细胞(induced pluripotent stem cells,iPSCs)和胚胎干细胞(embryonic stem cells,ESCs)具有许多共同特征,包括相似的形态、基因表达和体外分化谱。然而,iPSCs的基因组稳定性远低于ESCs。在本研究中,我们研究了iPSCs中DNA损伤修复的改变是否为其具有更大诱变倾向的原因。方法将小鼠iPSCs、ESCs和胚胎成纤维细胞暴露于电离辐射(4 Gy),导致双链DNA断裂。照射4 h后使用全基因组重测序评估DNA损伤修复的保真度。我们还分析了分别源自iPSCs或ESCs的小鼠的基因组稳定性。结果照射后,与胚胎干细胞和胚胎成纤维细胞相比,iPSCs具有较低的DNA损伤修复能力,有更多的体细胞突变和短片段插入缺失。iPSCs有更多的非同源末端连接DNA修复和更少的同源重组DNA修复。源自iPSCs的小鼠比ESCs小鼠以及C57对照小鼠的DNA损伤修复能力更低。结论本研究结果部分表明,iPSCs的低基因组稳定性及其在体内的高致瘤性是由DNA损伤修复的低保真度所致。Minjie Zhang Liu Wang Ke An Jun Cai Guochao Li Caiyun Yang Huixian Liu Fengxia Du Xiao Han Zilong Zhang Zitong Zhao Duanqing Pei Yuan Long Xin Xie Qi Zhou Yingli Sun 2019癌症2019,38,8:0
18Basophils as a potential therapeutic target in cancer显示文摘Basophils,which are considered as redundant relatives of mast cells and the rarest granulocytes in peripheral circulation,have been neglected by researchers in the past decades.Previous studies have revealed their vital roles in allergic diseases and parasitic infections.Intriguingly,recent studies even reported that basophils might be associated with cancer development,as activated basophils synthesize and release a variety of cytokines and chemokines in response to cancers.However,it is still subject to debate whether basophils function as tumor-protecting or tumor-promoting components;the answer may depend on the tumor biology and the microenvironment.Herein,we reviewed the role of basophils in cancers,and highlighted some potential and promising therapeutic strategies.Jicheng ZHANG Hanlin YIN Qiangda CHEN Guochao ZHAO Wenhui LOU Wenchuan WU Ning PU 2021Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021,22,12:0
