| 1 | A fundamental theorem for eco-environmental surface modelling and its applications显示文摘We propose a fundamental theorem for eco-environmental surface modelling(FTEEM) in order to apply it into the fields of ecology and environmental science more easily after the fundamental theorem for Earth’s surface system modeling(FTESM). The Beijing-Tianjin-Hebei(BTH) region is taken as a case area to conduct empirical studies of algorithms for spatial upscaling, spatial downscaling, spatial interpolation, data fusion and model-data assimilation, which are based on high accuracy surface modelling(HASM), corresponding with corollaries of FTEEM. The case studies demonstrate how eco-environmental surface modelling is substantially improved when both extrinsic and intrinsic information are used along with an appropriate method of HASM. Compared with classic algorithms, the HASM-based algorithm for spatial upscaling reduced the root-meansquare error of the BTH elevation surface by 9 m. The HASM-based algorithm for spatial downscaling reduced the relative error of future scenarios of annual mean temperature by 16%. The HASM-based algorithm for spatial interpolation reduced the relative error of change trend of annual mean precipitation by 0.2%. The HASM-based algorithm for data fusion reduced the relative error of change trend of annual mean temperature by 70%. The HASM-based algorithm for model-data assimilation reduced the relative error of carbon stocks by 40%. We propose five theoretical challenges and three application problems of HASM that need to be addressed to improve FTEEM. | Tianxiang YUE Na ZHAO Yu LIU Yifu WANG Bin ZHANG Zhengping DU Zemeng FAN Wenjiao SHI Chuanfa CHEN Mingwei ZHAO Dunjiang SONG Shihai WANG Yinjun SONG Changqing YAN Qiquan LI Xiaofang SUN Lili ZHANG Yongzhong TIAN Wei WANG Ying’an WANG Shengnan MA Hongsheng HUANG Yimin LU Qing WANG Chenliang WANG Yuzhu WANG Ming LU Wei ZHOU Yi LIU Xiaozhe YIN Zong WANG Zhengyi BAO Miaomiao ZHAO Yapeng ZHAO Yimeng JIAO Ufra NASEER Bin FAN Saibo LI Yang YANG John PWILSON | 2020 | Science China Earth Sciences2020，63，8： | 7 |
| 2 | Elevating H3K27me3 level sensitizes colorectal cancer to oxaliplatin显示文摘Histone methylation is a context-dependent modification that regulates gene expression,and the trimethylation of histone H3 lysine 27(H3K27me3)usually induces gene silencing.Overcoming colorectal cancer(CRC)chemoresistance is currently a huge challenge,but the relationship between H3K27me3 modification and chemoresistance remains largely unclear.Here,we found that H3K27me3 levels positively correlated with the metastasis-free survival of CRC patients and a low H3K27me3 level predicted a poor outcome upon chemotherapeutic drug treatment.Oxaliplatin stimulation significantly induced the expression of H3K27 lysine demethylase 6A/6B(KDM6A/6B),thus decreasing the level of H3K27me3 in CRC cells.Elevation of H3K27me3 level through KDM6A/6B depletion or GSK-J4(a KDM6A/6B inhibitor)treatment significantly enhanced oxaliplatin-induced apoptosis.Conversely,when inhibiting the expression of H3K27me3 by EPZ-6438,an inhibitor of the histone methyltransferase EZH2,the proportion of apoptotic cells remarkably decreased.In addition,the combination of GSK-J4 and oxaliplatin significantly inhibited tumor growth in an oxaliplatin-resistant patient-derived xenograft model.Importantly,we revealed that oxaliplatin treatment dramatically induced NOTCH2 expression,which was caused by downregulation of H3K27me3 level on the NOTCH2 transcription initiation site.Thus,the activated NOTCH signaling promoted the expression of stemness-related genes,which resulted in oxaliplatin resistance.Furthermore,oxaliplatin-induced NOTCH signaling could be interrupted by GSK-J4 treatment.Collectively,our findings suggest that elevating H3K27me3 level can improve drug sensitivity in CRC patients. | Qi Wang Xi Chen Yuhang Jiang Sanhong Liu Hanshao Liu Xiaohua Sun Haohao Zhang Zhi Liu Yu Tao Cuifeng Li Yiming Hu Dandan Liu Deji Ye Yongzhong Liu Mingliang Wang Xiaoren Zhang | 2020 | Journal of Molecular Cell Biology2020，12，2： | 6 |

| 4 | A blow-up criterion of strong solutions to the 2D compressible Navier-Stokes equations显示文摘We prove a blow-up criterion in terms of the upper bound of the density for the strong solution to 2D compressible Navier-Stokes equations in a bounded domain. The initial vacuum is allowed. The proof is based on the new a priori estimate for 2D compressible Navier-Stokes equations and a logarithmic estimate for Lamé system. | SUN YongZhong ZHANG ZhiFei | 2011 | Science China Mathematics2011，54，1： | 4 |

| 6 | Antibody Cocktail Exhibits Broad Neutralization Activity Against SARS-CoV-2 and SARS-CoV-2 Variants显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-Co V-2)has precipitated multiple variants resistant to therapeutic antibodies.In this study,12 high-affinity antibodies were generated from convalescent donors in early outbreaks using immune antibody phage display libraries.Of them,two RBD-binding antibodies(F61 and H121)showed high-affinity neutralization against SARS-Co V-2,whereas three S2-target antibodies failed to neutralize SARS-Co V-2.Following structure analysis,F61 identified a linear epitope located in residues G446–S494,which overlapped with angiotensinconverting enzyme 2(ACE2)binding sites,while H121 recognized a conformational epitope located on the side face of RBD,outside from ACE2 binding domain.Hence the cocktail of the two antibodies achieved better performance of neutralization to SARS-Co V-2.Importantly,these two antibodies also showed efficient neutralizing activities to the variants including B.1.1.7 and B.1.351,and reacted with mutations of N501 Y,E484 K,and L452 R,indicated that it may also neutralize the recent India endemic strain B.1.617.The unchanged binding activity of F61 and H121 to RBD with multiple mutations revealed a broad neutralizing activity against variants,which mitigated the risk of viral escape.Our findings revealed the therapeutic basis of cocktail antibodies against constantly emerging SARS-Co V-2 variants and provided promising candidate antibodies to clinical treatment of COVID-19 patients infected with broad SARS-Co V-2 variants. | Yuanyuan Qu Xueyan Zhang Meiyu Wang Lina Sun Yongzhong Jiang Cheng Li Wei Wu Zhen Chen Qiangling Yin Xiaolin Jiang Yang Liu Chuan Li Jiandong Li Tianlei Ying Dexin Li Faxian Zhan Youchun Wang Wuxiang Guan Shiwen Wang Mifang Liang | 2021 | Virologica Sinica2021，36，5： | 3 |

| 11 | B-cell-derived IL-10 promotes allergic sensitization in asthma regulated by Bcl-3显示文摘Aeroallergen sensitization,mainly mediated by lung epithelium and dendritic cells(DCs),is integral to allergic asthma pathogenesis and progression.IL-10 has a dual role in immune responses,as it inhibits myeloid cell activation but promotes B-cell responses and epithelial cell proliferation.Here,we report a proinflammatory function of B-cell-derived IL-10 modulated by Bcl-3 in allergic asthma.Specifically,Bcl-3^(−/−)mice showed elevated IL-10 levels and were found to be highly vulnerable to allergic asthma induced by house dust mites(HDMs).IL-10 had a positive correlation with the levels of the DC chemoattractant CCL-20 in HDM-sensitized mice and in patients with asthma and induced a selective increase in CCL-20 production by mouse lung epithelial cells.Blockade of IL-10 or IL-10 receptors during sensitization dampened both HDM-induced sensitization and asthma development.IL-10 levels peaked 4 h post sensitization with HDM and IL-10 was primarily produced by B cells under Bcl-3–Blimp-1–Bcl-6 regulation.Mice lacking B-cell-derived IL-10 displayed decreased lung epithelial CCL-20 production and diminished DC recruitment to the lungs upon HDM sensitization,thereby demonstrating resistance to HDM-induced asthma.Moreover,responses to HDM stimulation in Bcl-3^(−/−)mice lacking B-cell-derived IL-10 were comparable to those in Bcl-3^(+/+)mice.The results revealed an unexpected role of B-cell-derived IL-10 in promoting allergic sensitization and demonstrated that Bcl-3 prevents HDM-induced asthma by inhibiting B-cell-derived IL-10 production.Thus,targeting the Bcl-3/IL-10 axis to inhibit allergic sensitization is a promising approach for treating allergic asthma. | Guojun Qian Wenxia Jiang Donglin Sun Zhun Sun Anning Chen Hongwei Fang Jingyao Wang Yongzhong Liu Zhinan Yin Haiming Wei Hao Fang Xiaoren Zhan | 2023 | Cellular & Molecular Immunology2023，20，11： | 1 |
| 12 | Integrative method in lithofacies characteristics and 3D velocity volume of the Permian igneous rocks in H area, Tarim Basin显示文摘This paper introduces horizon control, seismic control, logging control and facies control methods through the application of the least squares fitting of logging curves, seismic inversion and facies-controlled techniques. Based on the microgeology and thin section analyses, the lithology, lithofacies and periods of the Permian igneous rocks are described in detail. The seismic inversion and facies-controlled techniques were used to find the distribution characteristics of the igneous rocks and the 3D velocity volume. The least squares fitting of the logging curves overcome the problem that the work area is short of density logging data. Through analysis of thin sections, the lithofacies can be classified into eruption airfall subfacies, eruption pyroclastic flow subfacies and eruption facies. | Yang Haijun Liu Yongfu Xie Huiwen Xu Yongzhong Sun Qi Wang Shuangshuang | 2013 | International Journal of Mining Science and Technology2013，23，2： | 1 |

| 20 | Multifunctional Gd-CuS loaded UCST polymeric micelles for MR/PA imaging-guided chemo-photothermal tumor treatment显示文摘Hepatocellular carcinoma(HCC)is a life-threatening disease for which there is no effective treatment currently.Novel theranostics simultaneously having excellent imaging and therapeutic functions are highly desired in cancer therapy.Herein,we develop the sialic acid(SA)modified polymeric micelles at an upper critical solution temperature(UCST)of 43℃(sialic acid-poly(ethylene glycol)-poly(acrylamide-co-acrylonitrile),SA-PEG-p(AAm-co-AN)),which further encapsulated with doxorubicin(DOX)and Gd-CuS nanoparticles(Gd-CuS NPs)for chemo-photothermal treatment of HCC guided by magnetic resonance(MR)/photoacoustic(PA)dual-mode imaging.The resultant SA-PEG-p(AAm-co-AN)/DOX/Gd-CuS(SPDG)had an excellent photothermal conversion efficiency,enabling SPDG with an instantaneous release behavior of DOX under near-infrared(NIR)irradiation.This study also revealed that SPDG could actively target to HCC,which was due to that SA had a high affinity with E-selectin overexpressed at the tumor site.Moreover,benefiting from the HCC-targeted ability and NIR light-controlled on-demand delivery of DOX,SPDG showed a superior potential in MR/PA dual-mode imaging-guided chemo-photothermal treatment.Overall,our study reveals that the designed SPDG may be used as an ideal multifunctional nanoplatform for cancer theranostics. | Yan Du Di Liu Mingchen Sun Gaofeng Shu Jing Qi Yuchan You Yiting Xu Kai Fan Xiaoling Xu Feiyang Jin Jun Wang Qiying Shen Luwen Zhu Xiaoying Ying Jiansong Ji Liming Wu Daren Liu Yongzhong Du | 2022 | Nano Research2022，15，3： | 0 |
