| 4 | Characteristics of Cd isotopic compositions and their genetic significance in the lead-zinc deposits of SW China显示文摘Up to now,the evaporation and condensation,as well as the biological absorption and inorganic absorptions,have been proved to be major factors in Cd isotope fractionation.And Cd isotopes have been widely applied in studies on the universal evolution and marine environment and so on.However,only a few researches have been conducted in applying Cd isotopes to trace the source of metallogenic material and the evolution of the ore-forming fluid in a complex mineralization environment,especially in a hydrothermal ore-formation system.We measured the Cd isotopic compositions of sphalerite,galena,and ores from five lead-zinc deposits in SW China,and found that the 114/110Cd values varied from 1.53‰to 0.34‰,with a total range of1.87‰,which is greater than most of measured geological samples.Meanwhile,through contrasting the Cd content with Cd isotopic compositions of different deposits,it may be concluded that different genetic lead-zinc deposits have different Cd content and isotopic compositions,which could be a tool for the studies on the origin of ore deposits.Also,the biomineralization and crystal fractionation may also result in Cd isotope fractionation.In a word,although the research of Cd isotopes is presently at the preliminary stage(especially in hydrothermal ore-formation system),this study demonstrated that Cd isotopes can give a clue in tracing the evolution of ore-forming fluid and metallogenic environment. | ZHU ChuanWei WEN HanJie ZHANG YuXu FAN HaiFeng FU ShaoHong XU Juan QIN TingRong | 2013 | Science China Earth Sciences2013，56，12： | 14 |

| 7 | Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event. | TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，3： | 12 |

| 10 | Major Modes of Short-Term Climate Variability in the Newly Developed NUIST Earth System Model(NESM)显示文摘A coupled earth system model(ESM) has been developed at the Nanjing University of Information Science and Technology(NUIST) by using version 5.3 of the European Centre Hamburg Model(ECHAM), version 3.4 of the Nucleus for European Modelling of the Ocean(NEMO), and version 4.1 of the Los Alamos sea ice model(CICE). The model is referred to as NUIST ESM1(NESM1). Comprehensive and quantitative metrics are used to assess the model's major modes of climate variability most relevant to subseasonal-to-interannual climate prediction. The model's assessment is placed in a multi-model framework. The model yields a realistic annual mean and annual cycle of equatorial SST, and a reasonably realistic precipitation climatology, but has difficulty in capturing the spring–fall asymmetry and monsoon precipitation domains. The ENSO mode is reproduced well with respect to its spatial structure, power spectrum, phase locking to the annual cycle, and spatial structures of the central Pacific(CP)-ENSO and eastern Pacific(EP)-ENSO; however, the equatorial SST variability,biennial component of ENSO, and the amplitude of CP-ENSO are overestimated. The model captures realistic intraseasonal variability patterns, the vertical-zonal structures of the first two leading predictable modes of Madden–Julian Oscillation(MJO), and its eastward propagation; but the simulated MJO speed is significantly slower than observed. Compared with the T42 version, the high resolution version(T159) demonstrates improved simulation with respect to the climatology, interannual variance, monsoon–ENSO lead–lag correlation, spatial structures of the leading mode of the Asian–Australian monsoon rainfall variability, and the eastward propagation of the MJO. | CAO Jian Bin WANG Baoqiang XIANG Juan LI WU Tianjie Xiouhua FU WU Liguang MIN Jinzhong | 2015 | Advances in Atmospheric Sciences2015，32，5： | 10 |
| 11 | Additively manufactured biodegradable porous magnesium implants for elimination of implant-related infections:An in vitro and in vivo study显示文摘Magnesium(Mg)alloys that have both antibacterial and osteogenic properties are suitable candidates for orthopedic implants.However,the fabrication of ideal Mg implants suitable for bone repair remains challenging because it requires implants with interconnected pore structures and personalized geometric shapes.In this study,we fabricated a porous 3D-printed Mg-Nd-Zn-Zr(denoted as JDBM)implant with suitable mechanical properties using selective laser melting technology.The 3D-printed JDBM implant exhibited cytocompatibility in MC3T3-E1 and RAW267.4 cells and excellent osteoinductivity in vitro.Furthermore,the implant demonstrated excellent antibacterial ratios of 90.0% and 92.1% for methicillin-resistant S.aureus(MRSA)and Escherichia coli,respectively.The 3D-printed JDBM implant prevented MRSA-induced implant-related infection in a rabbit model and showed good in vivo biocompatibility based on the results of histological evaluation,blood tests,and Mg2+deposition detection.In addition,enhanced inflammatory response and TNF-α secretion were observed at the bone-implant interface of the 3D-printed JDBM implants during the early implantation stage.The high Mg^(2+)environment produced by the degradation of 3D-printed JDBM implants could promote M1 phenotype of macrophages(Tnf,iNOS,Ccl3,Ccl4,Ccl5,Cxcl10,and Cxcl2),and enhance the phagocytic ability of macrophages.The enhanced immunoregulatory effect generated by relatively fast Mg^(2+)release and implant degradation during the early implantation stage is a potential antibacterial mechanism of Mg-based implant.Our findings indicate that 3D-printed porous JDBM implants,having both antibacterial property and osteoinductivity,hold potential for future orthopedic applications. | Kai Xie Nanqing Wang Yu Guo Shuang Zhao Jia Tan Lei Wang Guoyuan Li Junxiang Wu Yangzi Yang Wenyu Xu Juan Chen Wenbo Jiang Penghuai Fu Yongqiang Hao | 2022 | Bioactive Materials2022，7，2： | 8 |
| 12 | Modeling CADASIL vascular pathologies with patient-derived induced pluripotent stem cells显示文摘Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy(CADASIL)is a rare hereditary cerebrovascular disease caused by a NOTCH3 mutation.However,the underlying cellular and molecular mechanisms remain unidentified.Here,we generated non-integrative induced pluripotent stem cells(iPSCs)from fibroblasts of a CADASIL patient harboring a heterozygous NOTCH3 mutation(c.3226C>T,p.R1076C).Vascular smooth muscle cells(VSMCs)differentiated from CADASIL-specific iPSCs showed gene expression changes associated with disease phenotypes,including activation of the NOTCH and NF-kB signaling pathway,cytoskeleton disorganization,and excessive cell proliferation.In comparison,these abnormalities were not observed in vascular endothelial cells(VECs)derived from the patients iPSCs.Importantly,the abnormal upregulation of NF-kB target genes in CADASIL VSMCs was diminished by a NOTCH pathway inhibitor,providing a potential therapeutic strategy for CADASIL.Overall,using this iPSCbased disease model,our study identified clues for studying the pathogenic mechanisms of CADASIL and developing treatment strategies for this disease. | Chen Ling Zunpeng Liu Moshi Song Weiqi Zhang Si Wang Xiaoqian Liu Shuai Ma Shuhui Sun Lina Fu Qun Chu Juan Carlos Izpisua Belmonte Zhaoxia Wang Jing Qu Yun Yuan Guang-Hui Liu | 2019 | Protein & Cell2019，10，4： | 7 |
| 13 | Crystalline Silica Promotes Rat Fibrocyte Differentiation in Vitro,and Fibrocytes Participate in Silicosis in Vivo显示文摘Objective The aim of this study was to investigate the effects of Si O2 on fibrocytes and whether fibrocytes participate in silicosis in vivo. Methods A macrophagocyte(AM)/fibrocyte coculture system was established, and AMs were treated with 100 μg/mL SiO 2. Flow cytometry was used to detect the number of fibrocytes. Real‐time PCR was performed to measure the expression of collagen I, collagen III, and α‐SMA mR NA. The levels of collagen I, collagen III, and TGF‐β1 protein were determined by ELISA. Immunohistochemical staining was performed to measure α‐SMA protein expression. A rat silicosis model was induced by intratracheal instillation of SiO 2. Lung histopathological evaluation was conducted using HE and Masson's trichrome staining after 1 and 9 weeks. The number of fibrocytes in peripheral blood or lung tissue of rat was detected by flow cytometry. Double‐color immunofluorescence was applied to identify fibrocytes in the lung tissue. Results Peripheral blood monocytes were found to differentiate into fibrocytes in vitro in a time‐dependent manner, and exposure to crystalline silica might potentiate fibrocyte differentiation. In addition, fibrocytes were able to migrate from peripheral blood to the lung tissue, and the number of fibrocytes was increased after SiO 2 exposure. Conclusion Silica exposure potentiates fibrocyte differentiation, and fibrocytes may participate in silicosis in vivo. | LI Juan YAO Wu HOU Jian Yong Zhang Lin BAO Lei CHEN Hui Ting WANG Di YUE Zhong Zheng LI Yi Ping ZHANG Miao HAO Chang Fu | 2017 | Biomedical and Environmental Sciences2017，30，9： | 7 |

| 16 | Tumor suppressor genes on frequently deleted chromosome 3p in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma (NPC) is among the most common malignancies in southern China.Deletion of genomic DNA,which occurs during the complex pathogenesis process for NPC,represents a pivotal mechanism in the inactivation of tumor suppressor genes (TSGs).In many circumstances,loss of TSGs can be detected as diagnostic and prognostic markers in cancer.The short arm of chromosome 3 (3p) is a frequently deleted chromosomal region in NPC,with 3p21.1-21.2 and 3p25.2-26.1 being the most frequently deleted minimal regions.In recent years,our research group and others have focused on the identification and characterization of novel target TSGs at 3p,such as RASSF1A,BLU,RBMS3,and CHL1,in the development and progression of NPC.In this review,we summarize recent findings of TSGs at 3p and discuss some of these genes in detail.A better understanding of TSGs at 3p will significantly improve our understanding of NPC pathogenesis,diagnosis,and treatment. | Juan Chen Li Fu Li-Yi Zhang Dora L.

| 18 | Autophagy Attenuates MnCl2-induced Apoptosis in Human Bronchial Epithelial Cells显示文摘Objective To investigate the role of autophagy in MnC l2-induced apoptosis in human bronchial epithelial 16 HBE cells.Methods Cell proliferation was measured by MTT assay.Mitochondrial membrane potential(MMP) and apoptosis were measured by flow cytometry.Autophagic vacuoles were detected by fluorescence microscopy.Cellular levels of apoptosis and autophagy-related proteins were measured by western blotting.Results 16 HBE cell proliferation was inhibited by Mn Cl2 in a dose-and time-dependent manner.Mn Cl2-induced 16 HBE cell growth inhibition was related to MMP depolarization prior to the induction of apoptosis.Our data revealed that Mn Cl2-induced apoptosis in 16 HBE cells was mediated by decreased expression of Bcl-2 and increased levels of cleaved caspase-3.It was observed that when we exposed 16 HBE cells to MnCl_2 in a dose-dependent manner,the formation of autophagic vacuoles and the levels of LC-3B-II were elevated.RNA interference of LC3 B in these Mn Cl2-exposed cells demonstrated that MMP loss and apoptosis were enhanced.Additionally,the pan-caspase inhibitor Z-VAD-FMK increased the cellular levels of Bcl-2 and decreased apoptosis,but did not affect the cellular levels of LC3 B in Mn Cl2-treated 16 HBE cells.Conclusion Mn Cl2 dose-and time-dependently inhibits 16 HBE cell proliferation and induces MMP loss and apoptosis.Autophagy acts in a protective role against Mn Cl2-induced apoptosis in 16 HBE cells. | YUAN Zhun YING Xian Ping ZHONG Wei Jian TIAN Shi Min WANG Yu JIA Yong Rui CHEN Wen FU Juan Ling ZHAO Peng ZHOU Zong Can | 2016 | Biomedical and Environmental Sciences2016，29，7： | 5 |
| 19 | Fabrication of a nano-sized ZSM-5 zeolite with intercrystalline mesopores for conversion of methanol to gasoline显示文摘Carbon deposition during methanol to hydrocarbons leads to the quick deactivation of ZSM-5 catalyst and it is one of the major problems for this technology. Decreasing the crystal size or introducing mesopores into ZSM-5 zeolites can improve its diffusion property and decrease the coke formation. In this paper, nano-sized ZSM-5 zeolite with intercrystalline mesopores combining the mesoporous and nanosized structure was fabricated. For comparison, the mesoporous ZSM-5 and nano-sized ZSM-5 were also prepared. These catalyst samples were characterized by XRD, BET, NH3-TPD, TEM, Py-IR and TG techniques and used on the conversion of methanol to gasoline in a fixed-bed reactor at T = 405 °C, WHSV = 4.74 h-1and P = 1.0 MPa. It was found that the external surface area of the nano-sized ZSM-5 zeolite with intercrystalline mesopores reached 104 m2/g, larger than that of mesoporous ZSM-5(66 m2/g) and nanosized ZSM-5(76 m2/g). Catalytic lifetime of the nano-sized ZSM-5 zeolite with intercrystalline mesopores was 93 h, which was only longer than that of mesoporous ZSM-5(86 h), but shorter than that of nanosized ZSM-5(104 h). Strong acidity promoted the coke formation and thus decreased the catalytic lifetime of the nano-sized ZSM-5 zeolite with intercrystalline mesopores though it presented large external surface that could improve the diffusion property. The special zeolite catalyst was further dealuminated to decrease the strong acidity. After this, its coke formation rate was slowed and catalytic lifetime was prolonged to 106 h because of the large external surface area and decreased weak acidity. This special structural zeolite is a potential catalyst for methanol to gasoline reaction. | Tingjun Fu Jiangwei Chang Juan Shao Zhong Li | 2017 | Journal of Energy Chemistry2017，26，1： | 5 |
