| 1 | Infective viruses produced from full-length complementary DNA of swine vesicular disease viruses HK/70 strain显示文摘The full-length cDNA clone of swine vesicular disease virus HK/70 strain named pSVOK12 was constructed in order to study the antigenicity, replication, maturation and pathogenicity of swine vesicular disease virus. In vitro transcription RNA from pSVOK12 transfected IBRS-2 cells and the re- covered virus RNA were isolated and sequenced, then indirect hemagglutination test, indirect im- munofluorescence assays, eleectron microscope test, 50% tissue culture infecting dose (TCID50) assays and mouse virulence studies were performed to study the antigenicity and virulence of the recovered virus. The result showed that the infectious clones we ob- tained and the virus derived from pSVOK12 had the same biological properties as the parental strain HK/70. The full-length infectious cDNA clone, pSVOK12, will be very useful in studies of the anti- genicity, virulence, pathogenesis, maturation and replication of SVDV. | ZHENG Haixue LIU Xiangtao SHANG Youiun WU Jinyan BAI Xingwen JIN Ye SUN Shiqi GUO Huichen TIAN Hong FENG Xia YIN Shuanghui GUO Jianhong CONG Guozheng LIU Zaixin CHANG Huiyun MA Junwu XIE Qingge | 2006 | Chinese Science Bulletin2006，51，17： | 6 |

| 3 | Curcumin’s prevention of inflammation-driven early gastric cancer and its molecular mechanism显示文摘Worldwide,gastric cancer is the second leading cause of cancer deaths and the fifth most common malignant tumor.Gastric cancer is believed to be caused by a variety of factors,such as genetics,epigenetics,and environmental influences.Among the pathogenic factors,inflammation has been considered as one of the main risk factors for gastric cancer.There are currently limited ways to prevent gastric cancer.Although the combined application of aspirin and non-steroidal anti-inflammatory drugs can reduce the risk,it has great side effects and can easily cause gastric perforation or gastric bleeding.Therefore,an alternative plan is urgently needed.Curcumin is the yellow pigment in the rhizome of the plant turmeric.Current studies have found that curcumin has a protective effect on gastric mucosal damage caused by non-steroidal anti-inflammatory drugs,gastric mucosal damage in rats,and gastric mucosal damage caused by stress bleeding and Helicobacter pylori infection.Curcumin shows significant antiinflammatory and anti-cancer activities by regulating DNA methylation,histone modification,nuclear factor erythrocyte 2 related factor 2 and other related signal pathways.In this article,the latest evidence of curcumin for epigenetic changes in gastric cancer and its potential contribution to gastric cancer were discussed. | Wensen Zhang Na Cui Jin Ye Bingyou Yang Yanping Sun Haixue Kuang | 2022 | Chinese Herbal Medicines2022，14，2： | 3 |
| 4 | Enhanced energy storage performance under low electric field in Sm^(3+) doped AgNbO_(3) ceramics显示文摘Herein,Ag_(1-3x)Sm_(x)NbO_(3)(0≤x≤0.025)antiferroelectric ceramics were successfully synthesized by solid state methods.The effect of Sm 3þdoping on the structure,property and energy storage performance were studied.With the increasing Sm^(3+)concentrations,the average grain size decreased.Meanwhile,the stability of high temperature M phases(i.e.,the structure between T_(f) and T_(3))was expanded,which led to low loss for energy storage.Both of structure analysis and ferroelectric tests revealed the existence of weakly polar/AFE-like phase below T_(f).The Sm 3þdoping tended to suppress the ferroelectric behavior and expand the stability of antiferroelectricity.Consequently,a significantly enhanced energy storage performance(W_(rec)=3.8 J/cm^(3),η=73%)could be achieved in Ag_(0.97)Sm_(0.01)NbO_(3) ceramic,which was almost 1.5 times larger than that in non-doped AgNbO_(3)(W_(rec)=2.4 J/cm^(3),η=45%)under the similar applied field of 1705 kV/cm±.In particular,the performance of the ceramic showed great temperature stability with variation of±5%from 25℃ to 125℃.These results indicated that the Ag_(0.97)Sm_(0.01)NbO_(3) ceramic could be an ideal lead-free candidate used in the energy storage field. | Jing Li Li Jin Ye Tian Chao Chen Yu Lan Qingyuan Hu Chao Li Xiaoyong Wei Haixue Yan | 2022 | Journal of Materiomics2022，8，2： | 1 |

| 6 | Differential gene expression in porcine SK6 cells infected with wild-type and SAP domain-mutant foot-and-mouth disease virus显示文摘Foot-and-mouth disease virus(FMDV) is the causative agent of a highly contagious disease in livestock. The viral proteinaseL^(rop) of FMDV is involved in pathogenicity, and mutation of theL^(rop) SAP domain reduces FMDV pathogenicity in pigs. To determine the gene expression profiles associated with decreased pathogenicity in porcine cells, we performed transcriptome analysis using next-generation sequencing technology and compared differentially expressed genes in SK6 cells infected with FMDV containingL^(rop) with either a wild-type or mutated version of the SAP domain. This analysis yielded 1,853 genes that exhibited a ≥ 2-fold change in expression and was validated by real-time quantitative PCR detection of several differentially expressed genes. Many of the differentially expressed genes correlated with antiviral responses corresponded to genes associated with transcription factors, immune regulation, cytokine production, inflammatory response, and apoptosis. Alterations in gene expression profiles may be responsible for the variations in pathogenicity observed between the two FMDV variants. Our results provided genes of interest for the further study of antiviral pathways and pathogenic mechanisms related to FMDV L^(rop). | Zixin Ni Fan Yang Weijun Cao Xiangle Zhang Ye Jin Ruoqing Mao Xiaoli Du Weiwei Li Jianhong Guo Xiangtao Liu Zixiang Zhu Haixue Zheng | 2016 | Virologica Sinica2016，31，3： | 1 |
| 7 | Brain developmental and cortical connectivity changes in transgenic monkeys carrying the human-specific duplicated gene SRGAP2C显示文摘Human-specific duplicated genes contributed to phenotypic innovations during the origin of our own species, such as an enlarged brain and highly developed cognitive abilities. While prior studies on transgenic mice carrying the human-specific SRGAP2C gene have shown enhanced brain connectivity, the relevance to humans remains unclear due to the significant evolutionary gap between humans and rodents. In this study, to investigate the phenotypic outcome and underlying genetic mechanism of SRGAP2C, we generated transgenic cynomolgus macaques (Macaca fascicularis) carrying the human-specific SRGAP2C gene. Longitudinal MRI imaging revealed delayed brain development with region-specific volume changes, accompanied by altered myelination levels in the temporal and occipital regions. On a cellular level, the transgenic monkeys exhibited increased deep-layer neurons during fetal neurogenesis and delayed synaptic maturation in adolescence. Moreover, transcriptome analysis detected neotenic expression in molecular pathways related to neuron ensheathment, synaptic connections, extracellular matrix and energy metabolism. Cognitively, the transgenic monkeys demonstrated improved motor planning and execution skills. Together, our findings provide new insights into the mechanisms by which the newly evolved gene shapes the unique development and circuitry of the human brain. | Xiaoyu Meng Qiang Lin Xuerui Zeng Jin Jiang Min Li Xin Luo Kaimin Chen Haixu Wu Yan Hu Cirong Liu Bing Su | 2023 | National Science Review2023，10，11： | 1 |
| 8 | Rational Design of a Near-infrared Fluorescent Material with High Solid-state Efficiency,Aggregation-induced Emission and Live Cell Imaging Property显示文摘Near-infrared(NIR)fluorescent materials with high photoluminescent quantum yields(PLQYs)have wide application prospects.Therefore,we design and synthesize a D-A type NIR organic molecule,TPATHCNE,in which triphenylamine and thiophene are utilized as the donors and fumaronitrile is applied as the acceptor.We systematically investigate its molecular structure and photophysical property.TPATHCNE shows high T_(g) of 110℃ and T_(d) of 385℃ and displays an aggregation-induced emission(AIE)property.A narrow optical bandgap of 1.65 eV is obtained.The non-doped film of TPATHCNE exhibits a high PLQY of 40.3%with an emission peak at 732 nm,which is among the best values of NIR emitters.When TPATHCNE is applied in organic light-emitting diode(OLED),the electroluminescent peak is located at 716 nm with a maximum external quantum efficiency of 0.83%.With the potential in cell imaging,the polystyrene maleic anhydride(PMSA)modified TPATHCNE nanoparticles(NPs)emit strong fluorescence when labeling HeLa cancer cells,suggesting that TPATHCNE can be used as a fluorescent carrier for specific staining or drug delivery for cellular imaging.TPATHCNE NPs fabricated by bovine serum protein(BSA)are cultivated with mononuclear yeast cells,and the intense intracellular red fluorescence indicates that it can be adopted as a specific stain for imaging. | SHANG Anqi ZHAO Lele LI Zhenhua CHENG Zhuang JIN Haixu FENG Zijun CHEN Zhijun ZHANG Haiquan LU Ping | 2022 | Chemical Research in Chinese Universities2022，38，6： | 0 |
