2Interleukin-17 and its expanding biological functions显示文摘Interleukin-17(IL-17)and IL-17-producing cells have been shown to play important roles in inflammation and the immune response.IL-17 is believed to be mainly produced by T helper 17(Th17)cells,a unique helper T-cell subset different from Th1 and Th2 cells.Other subsets of T cells such as cdT and natural killer T(NKT)cells have also been found to produce IL-17 in response to innate stimuli.IL-17 acts as a proinflammatory cytokine that can induce the release of certain chemokines,cytokines,matrix metalloproteinases(MMPs)and antimicrobial peptides from mesenchymal and myeloid cells.This leads to the expansion and accumulation of neutrophils in the innate immune system and links innate and adaptive immunity in vivo.Furthermore,increasing evidence indicates that IL-17 and IL-17-producing cells are involved in the pathogenesis of various diseases such as allergies,autoimmune diseases,allograft transplantation and even malignancy.They may also play protective roles in host defense against infectious diseases and promote induction of cytotoxic T lymphocyte(CTL)responses against cancer.Targeting of the IL-17 axis is under investigation for the treatment of inflammatory disorders.Sheng Xu Xuetao Cao 2010Cellular & Molecular Immunology2010,7,3:50

4Casticin-induced apoptosis involves death receptor 5 upregulation in hepatocellular carcinoma cells显示文摘AIM:To investigate the apoptotic activities of casticin in hepatocellular carcinoma(HCC) cells and its molecular mechanisms.METHODS:PLC/PRF/5 and Hep G2 cell lines were cultured in vitro and the inhibitory effect of casticin on the growth of cells was detected by 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolim bromide(MTT) assay.The apoptotic cell death was examined using the cell apoptosis enzyme linked immunosorbent assay(ELISA) detection kit,flow cytometry(FCM) after propidium iodide(PI) staining and DNA agarose gel electrophoresis.The caspase activities were measured using ELISA.Reactive oxygen species(ROS) production was evaluated by FCM after dichlorodihydrofluorescein diacetate(DCFH-DA) probe labeling.Intracellular glutathione(GSH) content was measured using a glutathione assay kit.The expression of death receptor(DR)4 and DR5 proteins was analyzed by Western blotting and FCM.RESULTS:Casticin significantly inhibited the growth of human HCC(PLC/PRF/5 and Hep G2) cells in a dosedependent manner(P < 0.05).Casticin increased the percentage of the sub-G1 population in HCC cells in a concentration-dependent manner.The potency of casticin to PLC/PRF/5 cells was higher than that of 5-flurouracil(26.8% ± 4.8% vs 17.4% ± 5.1%) at 10 μmol/L for 24 h.Casticin increased the levels of Histone/DNA fragmentation and the levels of active caspase-3,-8 and-9 in a concentration-dependent manner(P < 0.05).Treatment with 30 μmol/L casticin for 24 h resulted in the formation of a DNA ladder.Casticin reduced the GSH content(P < 0.05),but did not affect the level of intracellular ROS in PLC/PRF/5 and Hep G2 cells.The thiol antioxidants,acetylcysteine(NAC) and GSH restored GSH content and attenuated casticin-induced apoptosis.In contrast,the nonthiol antioxidants,butylated hydroxyanisole and mannitol failed to do so.In the HCC cells treated with casticin for 24 h,DR5 protein level was increased.The expression of DR5 protein induced by casticin was inhibited by NAC.Pretreatment with DR5/Fc chimera protein,a blocking antibody,effectively attenuated the induction of apoptosis by casticin.CONCLUSION:Casticin-induced apoptosis of HCC cells is involved in GSH depletion and DR5 upregulation.Jun Yang Yun Yang Li Tian Xi-Feng Sheng Fei Liu Jian-Guo Cao 2011World Journal of Gastroenterology2011,17,38:21

7Exogenous NADPH ameliorates myocardial ischemia–reperfusion injury in rats through activating AMPK/mTOR pathway显示文摘Our previous study shows that nicotinamide adenine dinucleotide phosphate(NADPH)plays an important role in protecting against cerebral ischemia injury.In this study we investigated whether NADPH exerted cardioprotection against myocardial ischemia/reperfusion(I/R)injury.To induce myocardial I/R injury,rats were subjected to ligation of the left anterior descending branch of coronary artery for 30 min followed by reperfusion for 2 h.At the onset of reperfusion,NADPH(4,8,16 mg·kg?1·d?1,iv)was administered to the rats.We found that NADPH concentrations in plasma and heart were signi?cantly increased at 4 h after intravenous administration.Exogenous NADPH(8?16 mg/kg)signi?cantly decreased myocardial infarct size and reduced serum levels of lactate dehydrogenase(LDH)and cardiac troponin I(cTn-I).Exogenous NADPH signi?cantly decreased the apoptotic rate of cardiomyocytes,and reduced the cleavage of PARP and caspase-3.In addition,exogenous NADPH reduced mitochondrial vacuolation and increased mitochondrial membrane protein COXIV and TOM20,decreased BNIP3L and increased Bcl-2 to protect mitochondrial function.We conducted in vitro experiments in neonatal rat cardiomyocytes(NRCM)subjected to oxygen–glucose deprivation/restoration(OGD/R).Pretreatment with NADPH(60,500 nM)signi?cantly rescued the cell viability and inhibited OGD/R-induced apoptosis.Pretreatment with NADPH signi?cantly increased the phosphorylation of AMPK and downregulated the phosphorylation of mTOR in OGD/R-treated NRCM.Compound C,an AMPK inhibitor,abolished NADPH-induced AMPK phosphorylation and cardioprotection in OGD/R-treated NRCM.In conclusion,exogenous NADPH exerts cardioprotection against myocardial I/R injury through the activation of AMPK/mTOR pathway and inhibiting mitochondrial damage and cardiomyocyte apoptosis.NADPH may be a potential candidate for the prevention and treatment of myocardial ischemic diseases.Jiang Zhu Yi-fei Wang Xiao-ming Chai Ke Qian Ling-wei Zhang Peng Peng Pei-min Chen Jian-fang Cao Zheng-hong Qin Rui Sheng Hong Xie 2020Acta Pharmacologica Sinica2020,41,4:19

9Roles of mechanosensitive channel Piezo 1/2 proteins in skeleton and other tissues显示文摘Mechanotransduction is a fundamental ability that allows living organisms to receive and respond to physical signals from both the external and internal environments.The mechanotransduction process requires a range of special proteins termed mechanotransducers to convert mechanical forces into biochemical signals in cells.The Piezo proteins are mechanically activated nonselective cation channels and the largest plasma membrane ion channels reported thus far.The regulation of two family members,Piezol and Piezo2#has been reported to have essential functions in mechanosensation and transduction in different organs and tissues.Recently,the predominant contributions of the Piezo family were reported to occur in the skeletal system,especially in bone development and mechano-stimulated bone homeostasis.Here we review current studies focused on the tissue-specific functions of Piezol and Piezo2 in various backgrounds with special highlights on their importance in regulating skeletal cell mechanotransduction.In this review,we emphasize the diverse functions of Piezol and Piezo2 and related signaling pathways in osteoblast lineage cells and chondrocytes.We also summarize our current understanding of Piezo channel structures and the key findings about PIEZO gene mutations in human diseases.Lei Qin Tailin He Sheng Chen Dazhi Yang Weihong Yi Huiling Cao Guozhi Xiao 2021Bone Research2021,9,4:14
10Endogenous Hydrogen Peroxide Plays a Positive Role in the Upregulation of Heme Oxygenase and Acclimation to Oxidative Stress in Wheat Seedling Leaves显示文摘Pretreatment of lower H2O2 doses (0.05, 0.5 and 5 mM) for 24 h was able to dose-dependently attenuate lipid peroxidation in wheat seedling leaves mediated by further oxidative damage elicited by higher dose of H2O2 (150 mM) for 6 h, with 0.5 mM H2O2 being the most effective concentrations. Further results illustrated that 0.5 mM H2O2 pretreatment triggered the biphasic production of H2O2 during a 24 h period. We also noticed that only peak I (0.25 h) rather than peak Ⅱ (4 h) was approximately consistent with the enhancement of heme oxygenase (HO) activity, HO-1 gene expression. Meanwhile, enhanced superoxide dismutase (SOD) activity, Mn-SOD and Cu,Zn-SOD transcripts might be a potential source of peak I of endogenous H2O2. Further results confirmed that 0.5 mM H2O2 treatment for 0.5 h was able to upregulate HO gene expression, which was detected by enzyme activity determination, semi-quantitative reverse transcription-polymerase chain reaction and western blotting. Meanwhile, the application of N,N'-dimethylthiourea, a trap for endogenous H2O2, not only blocked the upregulation of HO, but also reversed the corresponding oxidation attenuation. Together, the above results suggest that endogenous H2O2 production (peak I) plays a positive role in the induction of HO by enhancing its mRNA level and protein expression, thus leading to the acclimation to oxidative stress.Xiao-Yue Chen Xiao Ding Sheng Xu Ren Wang Wei Xuan Ze-Yu Cao Jian Chen Hong-Hong Wu Mao-Bing Ye Wen-Biao Shen 2009Journal of Integrative Plant Biology2009,51,10:14
11Reproductive traits associated with invasiveness in Conyza sumatrensis显示文摘Conyza sumatrensis (Retz.) E. Walker, a member of Asteraceae, is a highly invasive species. However, its reproduction biology remains poorly known. To understand the role of reproductive traits in successful invasion of the species, we studied several traits of its reproductive system: the miniature capitulum and gynomonoecious sexual system, the biology and phenology of capitula and florets, pollen/ovule ratio, the mating system (self-compatibility), flower visitors, physical traits and dispersal potential of achenes, germination potential of achenes from manually pollinated capitula, and the association of these traits with invasiveness. Our study showed that the reproductive traits of autonomous seed production, versatile mating system of self- and cross-pollination, and generalized pollination system might contribute to the species' successful invasive capability. The invasiveness was further enhanced by the high and rapid production of achenes, as well as the high percentage, rapid germination rate and high dispersal capability of achenes. It was concluded that in annual or winter-annual weeds, autonomous seed production contributed significantly to the invasiveness of the species.jian-Hua HAO Sheng QIANG Qian-Qian LIU Fei CAO 2009Journal of Systematics and Evolution2009,47,3:13

13Insight-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 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
14Effect of warm bladder irrigation fluid for benign prostatic hyperplasia patients on perioperative hypothermia, blood loss and shiver: A meta-analysis显示文摘Objective:To find out whether warm bladder irrigation fluid can decrease the occurrence of perioperative hypothermia,blood loss and shiver in patients treated with benign prostatic hyperplasia(BPH).Method:A comprehensive literature review and meta-analysis that included randomized controlled trials(RCTs)related to temperature of irrigation fluid in the perioperative treatment for BPH was taken by researchers.The relevant literature were searched in Chinese database,such as Retrieval Chinese Journal Full-text Database,VIP Journal Database,Wanfang database,as well as in English search engine and database,including Embase,Cochrane and Medline till January 2018.The study quality was assessed by recommended standards from Cochrane Handbook(version 5.1.0).Results:A total of 28 RCTs and 3858 patients were included.The results showed that the incidences of shiver(risk ratio[RR]Z 0.32,95%confidence interval[CI]:0.28e0.36,p<0.001,I^2 Z 0%)and hypothermia(RR Z 0.36,95%CI:0.21e0.59,p<0.001,I^2 Z 67%)in the group of warm irrigation fluid were lower than the group having room-temperature fluid.Room-temperature irrigation fluid group caused a greater drop in body temperature compared to warm irrigation fluid group(p<0.001,I^2 Z 96%).We performed a narrative descriptive statistics only because of substantial heterogeneity.Conclusions:Warm bladder irrigation fluid can decrease the drop of body temperature and the incidence of hypothermia and shiver during and after the operation for BPH.Warm irrigation fluid should be considered as a standard practice in BPH surgeries.Jie Cao Xia Sheng Yan Ding Lingjuan Zhang Xiaoying Lu 2019Asian Journal of Urology2019,6,2:12
15The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
16An Object-based Approach for Two-level Gully Feature Mapping Using High-resolution DEM and Imagery: A Case Study on Hilly Loess Plateau Region, China显示文摘Gully feature mapping is an indispensable prerequisite for the motioning and control of gully erosion which is a widespread natural hazard. The increasing availability of high-resolution Digital Elevation Model(DEM) and remote sensing imagery, combined with developed object-based methods enables automatic gully feature mapping. But still few studies have specifically focused on gully feature mapping on different scales. In this study, an object-based approach to two-level gully feature mapping, including gully-affected areas and bank gullies, was developed and tested on 1-m DEM and Worldview-3 imagery of a catchment in the Chinese Loess Plateau. The methodology includes a sequence of data preparation, image segmentation, metric calculation, and random forest based classification. The results of the two-level mapping were based on a random forest model after investigating the effects of feature selection and class-imbalance problem. Results show that the segmentation strategy adopted in this paper which considers the topographic information and optimal parameter combination can improve the segmentation results. The distribution of the gully-affected area is closely related to topographic information, however, the spectral features are more dominant for bank gully mapping. The highest overall accuracy of the gully-affected area mapping was 93.06% with four topographic features. The highest overall accuracy of bank gully mapping is 78.5% when all features are adopted. The proposed approach is a creditable option for hierarchical mapping of gully feature information, which is suitable for the application in hily Loess Plateau region.LIU Kai DING Hu TANG Guoan ZHU A-Xing YANG Xin JIANG Sheng CAO Jianjun 2017Chinese Geographical Science2017,27,3:11

18Risk analysis for the highly pathogenic avian influenza in China's Mainland using meta-modeling显示文摘A logistic model was employed to correlate the outbreak of highly pathogenic avian influenza (HPAI) with related environmental factors and the migration of birds. Based on MODIS data of the normalized difference vegetation index, environmental factors were considered in generating a probability map with the aid of logistic regression. A Bayesian maximum entropy model was employed to explore the spatial and temporal correlations of HPAI incidence. The results show that proximity to water bodies and national highways was statistically relevant to the occurrence of HPAI. Migratory birds, mainly waterfowl, were important infection sources in HPAI transmission. In addition, the HPAI outbreaks had high spatiotemporal autocorrelation. This epidemic spatial range fluctuated 45 km owing to different distribution patterns of cities and water bodies. Furthermore, two outbreaks were likely to occur with a period of 22 d. The potential risk of occurrence of HPAI in China's Mainland for the period from January 23 to February 17, 2004 was simulated based on these findings, providing a useful meta-model framework for the application of environmental factors in the prediction of HPAI risk.CAO ChunXiang XU Min CHANG ChaoYi XUE Yong ZHONG ShaoBo FANG LiQun CAO WuChun ZHANG Hao GAO MengXu HE QiSheng ZHAO Jian CHEN Wei ZHENG Sheng LI XiaoWen 2010Chinese Science Bulletin2010,55,36:9
