| 1 | Interleukin 17-Producing γδ T Cells Increased in Patients with Active Pulmonary Tuberculosis显示文摘Although it has been known that γδ T cells may play an important role in the immune response to infection of Mycobacterium tuberculosis (M. tb), the mechanisms by which the γδ T cells participate in the innate and/or acquired immunity to tuberculosis (TB) have not been full elucidated. In the present study, 27 patients with active pulmonary TB and 16 healthy donors (HD) were performed. We found that proportion of IL-17-producing cells among lymphocyte was similar between TB patients and HD, whereas the proportions of γδ T cells in IL-17-producing cells (59.2%) and IL-17-producing cells in γδ T cells (19.4%) in peripheral blood were markedly increased in TB patients when compared to those in HD (43.9% and 7.7%, respectively). In addition, the proportions of IFN-γ-producing γδ T cells in TB patients were obviously lower than that in HD. Upon re-stimulated with M. tb heat-treated antigen (M. tb-HAg) in vitro, fewer IL-17-producing γδ T cells were generated from HD and TB patients, whereas IFN-γ-producing γδ T cells were increased in TB patients compared to that in HD. Our findings in TB patients and healthy human were consistent with other murine investigation that the IL-17-producing γδ T cells were main source of IL-17 in mouse model of BCG infection, suggesting that γδ T cells might be involved in the formation of tubercular granuloma in pulmonary TB patients, but need further identification. | Meiyu Peng Zhaohua Wang Chunyan Yao Lina Jiang Qili Jin Jing Wang Baiqing Li | 2008 | Cellular & Molecular Immunology2008,5,3: | 28 |

| 3 | Geographical characteristics of China’s wetlands derived from remotely sensed data显示文摘In this paper, we report the first wetland mapping of the entire China using Landsat enhanced thematic mapper plus (ETM+) data. These data were obtained from the Global Land Cover Facility at the University of Maryland spanning from 1999 to 2002. A total of 597 scenes of Landsat images were georeferenced and mosaiced. Manual image interpretation of satellite images was aided with elevation data, soil data, land cover/land use data and Google Earth. The minimum mapping unit is 10 pixel × 10 pixel, equivalent to 9 ha. The aim of our first round of mapping was only targeted at the boundary delineation of any type of wetland except those wetlands that are under agricultural use (i.e., paddy fields), which has already been well mapped by others. Our interpretation results indicate that a total of 359478 km2 of wetlands are of non-agricultural use. Among our preliminarily mapped wetland, 339353 km2 are inland wetland, 2786 km2 are non-agricultural artificial wetland, and 17609 km2 are coastal wetland. Because low-tide is rarely captured in satellite images, an under-estimation of coastal wetland is inevitable. We conducted some statistics based on our mapped wetlands and compared them with those previously obtained from a number of sources including a land cover/land use map made with satellite images during the late 1990s and early 2000s, a marshland map developed in approximately the same period, survey data of coastal wetland in early 1980s, and area data for approximately 400 larger patches of marshland in China compiled in 1996. Because some inconsistencies exist in the guidelines of those different wetland surveys, difference in area is expected. Some further comparison indicates that the wetland distributions derived from the preliminary wetland map are reasonable and more objective than other sources. The mapping process also indicated that the method adopted by us was efficient and cost-effective. We also found that in order to ensure comparability of the wetland maps developed at different times, a set of standard guidelines on the wetland categories to be mapped, and the mapping methods to be used must be well conceived, developed and effectively employed. We carried out some initial geographical analysis on the distribution of wetlands. | NIU ZhenGuo GONG Peng CHENG Xiao GUO JianHong WANG Lin HUANG HuaBing SHEN ShaoQing WU YunZhao WANG XiaoFeng WANG XianWei YING Qing LIANG Lu ZHANG LiNa WANG Lei YAO Qian YANG ZhenZhong GUO ZiQi DAI YongJiu | 2009 | Science China Earth Sciences2009,52,6: | 15 |
| 4 | Nitrogen removal via nitrite from municipal landfill leachate显示文摘A system consisting of a two-stage up-flow anaerobic sludge blanket (UASB), an anoxic/aerobic (A/O) reactor and a sequencing batch reactor (SBR), was used to treat landfill leachate. During operation, denitrification and methanogenesis took place simultaneously in the first stage UASB, and the effluent chemical oxygen demand (COD) was further removed in the second stage UASB. Then the denitrification of nitrite and nitrate in the returned sludge by using the residual COD was accomplished in the A/O reactor, and ammonia was removed via nitrite in it. Last but not least, the residual ammonia was removed in SBR as well as nitrite and nitrate which were produced by nitrification. The results over 120 d (60 d for phase I and 60 d for phase II) were as follows: when the total nitrogen (TN) concentration of influent leachate was about 2500 mg/L and the ammonia nitrogen concentration was about 2000 mg/L, the shortcut nitrification with 85%-90% nitrite accumulation was achieved stably in the A/O reactor. The TN and ammonia nitrogen removal efficiencies of the system were 98% and 97%, respectively. The residual ammonia, nitrite and nitrate produced during nitrification in the A/O reactor could be washed out almost completely in SBR. The TN and ammonia nitrogen concentrations of final effluent were about 39 mg/L and 12 mg/L, respectively. | WU Lina, PENG Chengyao, ZHANG Shujun, PENG Yongzhen Key Laboratory of Beijing for Water Quality Science and Water Environment Recovery Engineering, Beijing University of Technology, Beijing 100124, China. | 2009 | Journal of Environmental Sciences2009,21,11: | 14 |
| 5 | A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (http://gffzzc750bc0108fa4044sxqf9ownxkv9k6cxk.ffgz.tsg.suse.edu.cn/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants. | Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang | 2018 | Molecular Plant2018,11,11: | 7 |
| 6 | Chromosome-level genome of Himalayan yew provides insights into the origin and evolution of the paclitaxel biosynthetic pathway显示文摘Taxus,commonly known as yew,is a well-known gymnosperm with great ornamental and medicinal value.In this study,by assembling a chromosome-level genome of the Himalayan yew(Taxus wallichiana)with 10.9 Gb in 12 chromosomes,we revealed that tandem duplication acts as the driving force of gene family evolution in the yew genome,resulting in the main genes for paclitaxel biosynthesis,i.e.those encoding the taxadiene synthase,P450s,and transferases,being clustered on the same chromosome.The tandem duplication may also provide genetic resources for the nature to sculpt the core structure of taxoids at different positions and subsequently establish the complex pathway of paclitaxel by neofunctionalization.Furthermore,we confirmed that there are two genes in the cluster encoding isoenzymes of a known enzyme in the paclitaxel biosynthetic pathway.The reference genome of the Himalayan yew will serve as a platform for decoding the complete biosynthetic pathway of paclitaxel and understanding the chemodi-versity of taxoids in gymnosperms. | Jian Cheng Xiao Wang Xiaonan Liu Xiaoxi Zhu Zihe Li Huanyu Chu Qian Wang QianQian Lou Bijun Cai Yiqun Yang Xiaoyun Lu Kai Peng Dingyu Liu Yuwan Liu Lina Lu Huan Liu Ting Yang Qijin Ge Chengcheng Shi Guichun Liu Zhiwei Dong Xun Xu Wen Wang Huifeng Jiang Yanhe Ma | 2021 | Molecular Plant2021,14,7: | 6 |

| 8 | Distinct regulatory mechanism of immunoglobulin gene transcription in epithelial cancer cells显示文摘The restriction of immunoglobulin(Ig)expression to B lymphocytes is well established.However,several reports have confirmed that the Ig gene can be expressed in many non-B cancer cells and/or some normal cells.Our aim is to determine whether the Ig gene promoter can be activated in non-B cancer cells and to identify the regulatory mechanism for Ig gene expression.Our results show that the Ig promoter of VH4-59 was activated in several non-B cancer cell lines.Moreover,two novel positive regulatory elements,an enhancer-like element at 2800 to 2610 bp and a copromoter-like element at 2610 to 2300 bp,were identified in two epithelial cancer cell lines,HeLa S3 and HT-29.The octamer element(59-ATGCAAAT-39)located in the Ig promoter,a crucial element for B-cell-derived Ig gene transcription,was also very important for non-B-cell-derived Ig gene transcription.More importantly,we confirmed that octamer-related protein-1(Oct-1),but not Oct-2,was a crucial transcriptional factor for Ig gene transcription due to its ability to bind to the octamer element of the Ig promoter in epithelial cancer cells.These results suggested the presence of a distinct regulatory mechanism for Ig gene expression in non-B cancer cells. | Xiaohui Zhu Lina Wu Li Zhang Peng Hao Shuai Zhang Jing Huang Jie Zheng Yinan Liu Wenjun Li Yingmei Zhang Chunyan Zhou Youhui Zhang C Cameron Yin Xiaoyan Qiu | 2010 | Cellular & Molecular Immunology2010,7,4: | 5 |
| 9 | A quality evaluation strategy for Rhizoma coptidis from a variety of different sources using chromatographic fingerprinting combined with biological fingerprinting显示文摘Most of herbal medicines of different sources are used for the same treatment goal in clinic despite their tremendous differences of the quality.Because the clinical efficacy is closely related to the quality of medicines,the implementation of an effective quality control(QC)process is vital.Chemical methods based on content determination and chromatographic fingerprints(CFs)have been recommended as powerful tools.In spite of advances in QC,it is still difficult to determine that which of the chemical compositions can best reflect the correlation with the desired biological activity.Herein,we have focused on the biological activities of multi-source herbal medicines to establish an analytical method.By looking for correlations between the biological activities and their chemical compositions,the method can identify reasonable chemical indicators or chemical methods with biological activity information.In this study,high-performance liquid chromatography(HPLC)and microcalorimetry are combined as a useful method for evaluating the quality of Rhizoma coptidis from different sources.The results of biological fingerprints(BFs)showed that the antibacterial activity sequence of R.coptidis of different sources was Coptis teeta Wall.(CT)>Coptis chinensis Franch.(CC)>Coptis deltoidea C.Y.Cheng et Hsiao(CD).The'spectrum-activity'relationships between CFs and BFs were investigated using the canonical correlation analysis(CCA).Compared with the CCA result of CFs and BFs,the canonical correlation coefficient r1and r2were 0.9974 and 0.9752,respectively.It revealed that there are a close correlation between the spectrum-activity relationships and several of the major anti-bacterial components in the CFs,including jatrorrhizine,coptisine,palmatine,and berberine.Of course,R.coptidis was only a representative of multisource medical plants.The result of the current study will provide an effective reference for evaluating the quality of multisource herbal medicines. | LI JunXian YAN Dan MA LiNa XIONG Yin YAN ChunXia LI BaoCai PENG Cheng XIAO XiaoHe | 2013 | Chinese Science Bulletin2013,58,33: | 5 |

| 11 | Targeted peptide-Au cluster binds to epidermal growth factor receptor (EGFR) in both active and inactive states: a clue for cancer inhibition through dual pathways显示文摘The epidermal growth factor receptor(EGFR) has become an important target protein in anticancer drug development. Meanwhile, peptide-Au cluster has been proposed as potential targeted nano-drug assembled by targeting peptide. Here, we designed and synthesized a novel peptide-Au cluster as Au_(10)Peptide_5 to target to EGFR. We found Au_(10)Peptide_5 could target to the natural binding sites of all EGFRs at membrane in both active and inactive states by molecular simulations. Its targeted ability was further verified by the co-localization and blocking experiments. We also study the configuration modifications of both active and inactive EGFRs after binding by Au_(10)Peptide_5. For active EGFR, the absorbed Au_(10)Peptide_5 might replace the natural ligand in EGFR endocytosis process. Then, the peptide-Au cluster in endochylema could inhibit the cancer relating enzyme activity including thioredoxin reductase1(TrxR1) and induce the oxidative stress mediated apoptosis in tumor cells. For inactive EGFR, it was retained in inactive state by Au_(10)Peptide_5 binding to inhibit dimerization of EGFR for anticancer. Both pathways might be applied in anticancer drug development based on the theoretical and experimental study here. | Peng Zhang Jiao Zhai Xueyun Gao Hongkang Zhao Wenyong Su Lina Zhao | 2018 | Science Bulletin2018,63,6: | 4 |
| 12 | Alterations of peripheral CD4^(+)CD25^(+)Foxp3^(+)T regulatory cells in mice with STZ-induced diabetes显示文摘Complications arising from abnormal immune responses are the major causes of mortality and morbidity in diabetic patients.CD4^(+)CD25^(+)T regulatory cells(Tregs)play pivotal roles in controlling immune homeostasis,immunity and tolerance.The effect of hyperglycemia on CD4^(+)CD25^(+)Tregs has not yet been addressed.Here we used streptozotocin(STZ)-induced diabetic mice to study the effects of long-term hyperglycemia on CD4^(+)CD25^(+)Tregs in vivo.Four months after the onset of diabetes,the frequency of CD4^(+)CD25^(+)Foxp3^(+)T regulatory cells was significantly elevated in the spleen,peripheral blood lymphocytes(PBLs),peripheral lymph nodes(pLNs)and mesenteric LNs(mLNs).CD4^(+)CD25^(+)Tregs obtained from mice with diabetes displayed defective immunosuppressive functions and an activated/memory phenotype.Insulin administration rescued these changes in the CD4^(+)CD25^(+)Tregs of diabetic mice.The percentage of thymic CD4^(+)CD25^(+)naturally occurring Tregs(nTregs)and peripheral CD41Helios1Foxp31 nTregs were markedly enhanced in diabetic mice,indicating that thymic output contributed to the increased frequency of peripheral CD4^(+)CD25^(+)Tregs in diabetic mice.In an in vitro assay in which Tregs were induced fromCD4^(+)CD25^(+)T cells by transforming growth factor(TGF)-b,high glucose enhanced the efficiency of CD4^(+)CD25^(+)Foxp3^(+)T inducible Tregs(iTregs)induction.In addition,CD4^(+)CD25^(+)T cells from diabetic mice were more susceptible to CD4^(+)CD25^(+)Foxp3^(+)TiTreg differentiation than those cells from control mice.These data,together with the enhanced frequency of CD4^(+)CD25^(+)Foxp3^(+)T iTregs in the periphery of mice with diabetes,indicate that enhanced CD4^(+)CD25^(+)Foxp3^(+)T iTreg induction also contributes to a peripheral increase in CD4^(+)CD25^(+)Tregs in diabetic mice.Our data show that hyperglycemia may alter the frequency of CD4^(+)CD25^(+)Foxp3^(+)T Tregs in mice,which may result in late-state immune dysfunction in patients with diabetes. | Yu Zhen Lina Sun He Liu Kaizhong Duan Chun Zeng Lianjun Zhang Di Jin Jianxia Peng Wenjun Ding Yong Zhao | 2012 | Cellular & Molecular Immunology2012,9,1: | 4 |
| 13 | Improved oxygen reduction reaction via a partially oxidized Co-CoO catalyst on N-doped carbon synthesized by a facile sand-bath method显示文摘High active and durable non-noble metal electrocatalysts are urgently developed to satisfy the high performance oxygen reduction reaction(ORR). We successfully synthesized Co-CoOx anchored on nitrogen-doped carbon via a facile sand-bath method(SBM), i.e., Co-CoOx/N-C(SBM). The as-obtained Co-CoOx/N-C(SBM) exhibited overwhelming superiorities to Co-CoO/N-C prepared by conventional heat treatment(CHT), particularly in electrochemical performance of ORR. Although Co-CoOx/N-C(SBM)showed smaller specific surface area of 276.8 m^2/g than that of 939.5 m^2/g from Co-CoO/N-C(CHT), the Co-CoOx/N-C(SBM) performed larger pore diameter and more Co_3O_4 active component resulting in better ORR performance in 0.1 mol/L KOH solution. The Co-CoO_x/N-C(SBM) delivered onset potential of 0.91 V vs. RHE, mid-wave potential of 0.85 V vs. RHE and limited current density of 5.46 mA/cm^2 much better than those of the Co-CoO/N-C(CHT). Furthermore, Co-CoOx/N-C(SBM) showed greater stability and better methanol tolerance superior to the commercial 20 wt% Pt/C. | Libing Hu Feng Yu Huifang Yuan Gang Wang Mincong Liu Lina Wang Xueyan Xue Banghua Peng Zhiqun Tian Bin Dai | 2019 | Chinese Chemical Letters2019,30,3: | 4 |

| 15 | Desertification: China provides a solution to a global challenge显示文摘Desertification has been caused by various factors and is a major environmental problem and development bottleneck faced by the world. It is also a serious threat to ecological security and to sustainable economic and social development. As a stubborn world problem, focused on by the United Nations 2030 sustainable development goal 15.3, China aims to combat desertification by implementing the 'eight-column fourbeam' strategy, and also suggest the 'four-medicine'approach for global desertification governance. This includes the development of the United Nations Convention to Combat Desertification protocol, unified global compliance and compliance metrics; building a global observation network, and monitoring land changes based on remote sense; preparing the global natural desert(heritage) list, leaving the original deserts for future generations; initiating the global action of combating desertification, and striving to achieve a land degradationneutral world by 2030. | Yingshuang BAO Leilei CHENG Yanfeng BAO Liu YANG Lina JIANG Chao LONG Zhe KONG Peng PENG Jun XIAO Qi LU | 2017 | Frontiers of Agricultural Science and Engineering2017,4,4: | 3 |

| 17 | Axial gradient excitation accelerates volumetric imaging of two-photon microscopy显示文摘Two-photon excitation fluorescence microscopy(TPM),owing to its capacity for subcellular resolution,intrinsic optical sectioning,and superior penetration depth in turbid samples,has revolutionized biomedical research.However,its layer-by-layer scanning to form a three-dimensional image inherently limits the volumetric imaging speed and increases phototoxicity significantly.In this study,we develop a gradient excitation technique to accelerate TPM volumetric imaging.The axial positions of the fluorophores can be decoded from the intensity ratio of the paired images obtained by sequentially exciting the specimen with two axially elongated two-photon beams of complementary gradient intensities.We achieved a 0.63μm axial localization precision and demonstrate the flexibility of the gradient TPM on various sparsely labeled samples,including bead phantoms,mouse brain tissues,and live macrophages.Compared with traditional TPM,our technique improves volumetric imaging speed(by at least sixfold),decreases photobleaching(i.e.,less than 2.07±2.89%in 25 min),and minimizes photodamages. | Yufeng Gao Xianyuan Xia Lina Liu Ting Wu Tingai Chen Jia Yu Zhili Xu Liang Wang Fei Yan Zhuo Du Jun Chu Yang Zhan Bo Peng Hui Li Wei Zheng | 2022 | Photonics Research2022,10,3: | 3 |

| 19 | LHCGR and ALMS1 defects likely cooperate in the development of polycystic ovary syndrome indicated by double-mutant mice显示文摘Polycystic ovary syndrome(PCOS)is a heterogeneous disorder with evidence of polygenetic components,and obesity may be a risk factor for hyperandrogen ism.Previous studies have shown that LHCGR is en riched in the ovary and LHCGR deficiency causes infertility without typical PCOS phenotypes.ALMS1 is implicated in obesity and hyperandrogenism,the common phenotypes among PCOS patients.Through whole-exome sequencing of 22 PCOS families and targeted candidate gene sequencing of additional 65 sporadic PCOS patients,we identified potential causative mutations in LHCGR and ALMS1 in a sibling-pair PCOS family and three sporadic PCOS patients.The expression of LHCGRL638 P in granulosa-like tumor cell line(KGN)cells promoted cyclic adenosine monophosphate production and granulosa cell proliferation,indicating that LHCGRL638 P is an activating mutation.Lhcgr~(L642 P/L642 P)mice showed an irregular estrous cycle,reduced follicles with dynamic folliculogenesis,and increased testosterone(T),estradiol(E2),and dehydroepiandrosterone.Lhcgr~(+/L642 P)AIms1~(+/PB)mice displayed increased T and E2 but decreased late secondary and preovulatory follicles.We showed that activating mutation of LHCGR likely plays important roles in the pathophysiology of PCOS involving abnormal reproductive physiology,whereas ALMS1 deficiency may promote anovulatory infertility via elevated androgens,suggesting that the disturbed LHCGR and ALMS1 cooperatively induce PCOS phenotypes,characterized as anovulation and hyperandrogenemia frequently observed in PCOS patients with obesity. | Li Yu Lina Wang Wufan Tao Wenxiang Zhang Shuanghao Yang Jian Wang Jia Fei Rui Peng Yiming Wu Xiumei Zhen Hong Shao Weiyue Gu Rong Li Bai-Lin Wu Hongyan Wang | 2021 | Journal of Genetics and Genomics2021,48,5: | 3 |
| 20 | Phylogenetic Analysis of the Dengue Virus Strains Causing the 2019 Dengue Fever Outbreak in Hainan,China显示文摘Dengue virus is an arthropod-borne pathogen that is transmitted to humans primarily by Aedes spp.mosquitos,causing the acute infectious disease,dengue fever(DF).Until 2019,no dengue outbreak had been reported in Hainan Province for over 20 years.However,in early September of 2019,an increasing number of infected cases appeared and the DF outbreak lasted for over one month in Haikou City,Hainan Province.In our study,we collected 97 plasma samples from DF patients at three hospitals,as well as 1585 mosquito larvae samples from puddles in different areas of Haikou.There were 49(50.5%)plasma samples found to be strongly positive and 9(9.3%)plasma samples were weakly positive against the NS1 antigen.We discovered DENV both in the patient's plasma samples and mosquito larvae samples,and isolated the virus from C6/36 cells inoculated with the acute phase serum of patients.Phylogenetic analysis revealed that the new strains were the most closely related to the epidemic strain in the southern regions of China,belonging to lineageⅣ,genotypeⅠ,DENV-1.Compared to the seven closest strains from neighboring countries and provinces,a total of 18 amino acid mutations occurred in the coding sequences(CDS)of the new isolated strain,DENV1 HMU-HKU-2.Our data shows that dengue virus is re-emerged in Hainan,and pose new threats for public health.Thus regular molecular epidemiological surveillance is necessary for control and prevention of DENV transmission. | Jiang Du Liyuan Zhang Xiaoyuan Hu Ruoyan Peng Gaoyu Wang Yi Huang Wenqi Wang Kunliang Wu Qiang Wang Haoxiang Su Fan Yang Yun Zhang Chuanning Tang Xiuji Cui Lina Niu Gang Lu Meifang Xiao Yongguo Du Feifei Yin | 2021 | Virologica Sinica2021,36,4: | 2 |
