1Ecological restoration and recovery in the wind-blown sand hazard areas of northern China: relationship between soil water and carrying capacity for vegetation in the Tengger Desert显示文摘The main prevention and control area for wind-blown sand hazards in northern China is about 320000 km2 in size and includes sandlands to the east of the Helan Mountain and sandy deserts and desert-steppe transitional regions to the west of the Helan Mountain.Vegetation recovery and restoration is an important and effective approach for constraining wind-blown sand hazards in these areas.After more than 50 years of long-term ecological studies in the Shapotou region of the Tengger Desert,we found that revegetation changed the hydrological processes of the original sand dune system through the utilization and space-time redistribution of soil water.The spatiotemporal dynamics of soil water was significantly related to the dynamics of the replanted vegetation for a given regional precipitation condition.The long-term changes in hydrological processes in desert areas also drive replanted vegetation succession.The soil water carrying capacity of vegetation and the model for sand fixation by revegetation in aeolian desert areas where precipitation levels are less than 200 mm are also discussed.LI XinRong ZHANG ZhiShan TAN HuiJuan GAO YanHong LIU LiChao WANG XinPing 2014Science China(Life Sciences)2014,57,5:39

3Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection.Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin 2020Animal Models and Experimental Medicine2020,3,1:22
4Patterns of shrub species richness and abundance in relation to environmental factors on the Alxa Plateau:Prerequisites for conserving shrub diversity in extreme arid desert regions显示文摘Shrub species are considered the dominant plants in arid desert ecosystems,unlike in semiarid steppe zones or in grassland ecosystems.On the Alxa Plateau,northern China,sparse vegetation with cover ranging from 15% to 30% is characterized mainly by multifarious shrubs because herbaceous species are strongly restricted by the extreme drought climate,wind erosion,overgrazing and sand burial.Patterns in shrub species richness and species abundance in relation to environmental conditions were examined by DCA(detrended correspondence analysis) and interpreted by a biplot.The rela-tionships between species diversity and environmental factors were examined using regression analyses.Our results show that the distributions of the shrub species in response to environmental conditions can be grouped into four ecological types,corresponding with the biological traits of the shrubs and their responses to the gradients of soil texture and soil water content.Patterns in species richness and species abundance were mainly determined by the deeper soil water content,instead of the soil texture as hypothesized by numerous studies in semiarid grasslands.With exception of the deeper soil water content,soil organic matter and total N content were positively correlated with species abundance,while pH was negatively correlated with it.These findings imply that it is vital for cur-rent shrub diversity conservation to reduce agricultural water use in the middle reaches of the Heihe River,which supplies water for the lower reaches in the western parts of the plateau,and to reduce the amount of groundwater exploitation and urban and oasis water use,to increase the water supply from Helan Mountain to the eastern desert of the Alxa Plateau.XinRong Li HuiJuan Tan MingZhu He XinPing Wang XiaoJun Li 2009Science China Earth Sciences2009,52,5:17

6Rainfall interception by sand-stabilizing shrubs related to crown structure显示文摘On the edge of the Tengger Desert in northern China,revegetation has changed the landscape from moving dunes to stabilized dunes covered by shrubs,which further modifies the pattern of rainfall redistribution.To study rainfall interception loss by shrubs and its relationship to rainfall properties and crown structure,throughfalls passing through crowns of Artemisia ordosica Krash.and Caragana korshinskii Kom.were measured using nine PVC cups under the canopy of each of the two shrubs during 73 rain events over a three-year period,with total rainfall of 260.9 mm.Interception losses of gross rainfall by A.ordosica and C.korshinskii account for 15% and 27% of the total on a crown area basis,and 6% and 11% on a ground area basis,respectively.Individual throughfall(T) and interception(I) were significantly related to rainfall amount(Pg),duration(D),and intensity(R).Ratios of throughfall to rainfall(T/Pg) and interception to rainfall(I/Pg) were not only significantly related to Pg,D,and R,but also to shrub species,and interactions of species with crown volume(CV) and leaf area index(LAI).Under most rain events,interceptions by C.korshinskii with greater CV and LAI were significantly higher than those by A.ordosica,and more rainfall interception occurred at locations closer to the stems of the two shrubs.For C.korshinskii,I/Pg had a significant positive linear relation with CV and LAI,while T/Pg had a significant negative linear relation with them.CV has a greater influence on T/Pg and I/Pg than does LAI.Using a regression method,canopy water storage capacities are estimated to be 0.52 and 0.68 mm,and free throughfall coefficient to be 0.62 and 0.47 for A.ordosica and C.korshinskii,respectively.ZhiShan Zhang 1*,XinRong Li 1,XueJun Dong 2,XiaoHong Jia 1,MingZhu He 1,HuiJuan Tan 1 1.Shapotou Desert Research and Experiment Station,Cold and Arid Regions Environmental and Engineering Research Institute,Chinese Academy of Sciences,Lanzhou,Gansu 730000,China.2.Central Grasslands Research Extension Center,North Dakota State University,Streeter,ND 58483,USA. 2009Research in Cold and Arid Regions2009,1,2:9
7Do major customers promote firms’ innovation?显示文摘This study examines whether and how a concentrated supply chain relationship affects a firm’s innovation decisions. Using data from Chinese listed firms in the manufacturing industry, we find that a concentrated customer base constrains a firm’s R&D investment, where a 1% increase in customer concentration is associated with a 0.011% decrease in R&D investment. To establish causality, we use the instrumental variable method, the reverse causality model, and the Granger causality test to re-examine the relationship and arrive at a consistent conclusion. Results from mechanism analysis suggest that a concentrated customer base constrains the internal fund availability and that the negative relationship between customer concentration and firms’ innovation is less pronounced for firms with more external financial support. Additional analysis reveals that the negative effect of customer concentration mainly affects R&D investment expenditure and that customer concentration also constrains innovation output in China. Overall, our paper reveals the dark side of close customer-supplier relationships and provides new insights into how supply chain relationships affect firms’ innovation decisions.Jinsong Tan Huijuan Cao Xiangting Kong 2019China Journal of Accounting Research2019,,2:8
8A Crucial Role of GA-Regulated Flavonol Biosynthesis in Root Growth of Arabidopsis显示文摘Flavonols have been demonstrated to play many important roles in plant growth, development, and communication with other organisms. Flavonol biosynthesis is spatiotemporally regulated by the subgroup 7 R2R3-MYB (SG7 MYB) transcription factors including MYB11/MYB12/MYB111. However, whether SG7- MYB activity is subject to post-translational regulation remains unclear. Here, we show that gibberellic acid (GA) inhibits flavonol biosynthesis via DELLA proteins in Arabidopsis. Protein-protein interaction analyses revealed that DELLAs (RGA and GAI) interacted with SG7 MYBs (MYB12 and MYB111) both in vitro and in vivo, leading to enhanced affinity of MYB binding to the promoter regions of key genes for flavonol biosynthesis and thus increasing their transcriptional levels. We observed that the level of auxin in the root tip was negatively correlated with root flavonol content. Furthermore, genetic assays showed that loss-of-function mutations in MYB 12, which is predominantly expressed in roots, partially rescued the short-root phenotype of the GA-deficient mutant ga1-3 by increasing root meristem size and mature cell size. Consistent with these observations, exogenous application of the flavonol quercetin restored the root meristem size of myb12 ga1-3 to that of ga1-3. Taken together, our data elucidate a molecular mechanism by which GA promotes root growth by directly reducing flavonol biosynthesis.Huijuan Tan Cong Man Ye Xie Jijun Yan Jinfang Chu Jirong Huang 2019Molecular Plant2019,12,4:8
9Three Novel Real-Time RT-PCR Assays for Detection of COVID-19 Virus显示文摘What is already known on this topic?A novel human coronavirus,known as SARS-CoV-2 or 2019-nCoV,is the causative agent of the coronavirus disease 2019(COVID-19).We have released the primers and probes of real-time reverse transcription polymerase chain reaction(rRT-PCR)assays for the laboratory detection of COVID-19 infection.What is added by this report?Here we provide detailed technical data and evaluate the performance of three novel rRT-PCR assays targeting the ORF1ab,N,and E genes for detection of COVID-19 infection.The application of rRT-PCR assays among four types of specimens(alveolar lavage,sputum,throat swabs,and stool)from patients with COVID-19 indicated that the mean viral loads detected in sputum were higher than other specimens.What are the implications for public health practice?These rRT-PCR assays reported here could be used for laboratory diagnosis of COVID-19 infection with high sensitivity,specificity,and applicability.Sputum rather than throat swabs and stool should be a priority for specimen collection for laboratory detection of COVID-19.Peihua Niu Roujian Lu Li Zhao Huijuan Wang Baoying Huang Fei Ye Wenling Wang Wenjie Tan 2020China CDC weekly2020,2,25:8
10Potential and policy issues for sustainable development of wind power in China显示文摘This paper presents a macroscopic view on the prevailing policy and potential issues in respect of the sustainable wind power development in China.It starts by analyzing the characteristics of wind power resources and pin-pointing the relationship between the regulatory policies and various economic,taxation,legal and grid integration attributes relating to the wind power development.Then it follows by analyzing the status quo and capabilities of the wind power manufacturing industry in China including its operational efficiency and grid integration standards.The economic and environmental benefits are estimated by relating to the associated costing analysis in respect of the major contributing factors such as manufacturing,operational and financial factors.Results of the associated benefits analysis indicate that the use of the wind power generation helps to save a significant equivalent amount of standard coal consumption resulting to reduction of emission effectively.Finally,the potential of wind power development in China is shown to be affirmative and the sustainable energy policy is effectively implemented in China.Zhongfu TAN H.W.NGAN Yang WU Huijuan ZHANG Yihang SONG Chao YU 2013Journal of Modern Power Systems and Clean Energy2013,1,3:7
11Summary of the Detection Kits for SARS-CoV-2 Approved by the National Medical Products Administration of China and Their Application for Diagnosis of COVID-19显示文摘The on-going global pandemic of coronavirus disease 2019(COVID-19)caused by a novel coronavirus called severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has been underway for about 11 months.Through November 20,2020,51 detection kits for SARS-CoV-2 nucleic acids(24 kits),antibodies(25 kits),or antigens(2 kits)have been approved by the National Medical Products Administration of China(NMPA).Convenient and reliable SARS-CoV-2 detection assays are urgently needed worldwide for strategic control of the pandemic.In this review,the detection kits approved in China are summarised and the three types of tests,namely nucleic acid,serological and antigen detection,which are available for the detection of COVID-19 are discussed in detail.The development of novel detection kits will lay the foundation for the control and prevention of the COVID-19 pandemic globally.Ruhan A Huijuan Wang Wenling Wang Wenjie Tan 2020Virologica Sinica2020,35,6:5
12Interaction Between Variations in Dopamine D2 and Serotonin 2A Receptor is Associated with Short-Term Response to Antipsychotics in Schizophrenia显示文摘Dear Editor,Schizophrenia is a chronic and debilitating brain disorder,which has a strong genetic component with heritability ranging from 66%to 85%[1,2].Currently,antipsychotic drugs remain the most effective treatment for the psychotic symptoms of schizophrenia[3].Because of the severe sideeffects of first-generation antipsychotics(FGAs),secondgeneration antipsychotics(SGAs)have become more widely used in the treatment of schizophrenia.Liansheng Zhao Huijuan Wang Yamin Zhang Jinxue Wei Peiyan Ni Hongyan Ren Gang Li Qiang Wang Gavin P Reynolds Weihua Yue Wei Deng Hao Yan Liwen Tan Qi Chen Guigang Yang Tianlan Lu Lifang Wang Fuquan Zhang Jianli Yang Keqing Li Luxian Lv Qingrong Tan Yinfei Li Hua Yu Hongyan Zhang Xin Ma Fude Yang Lingjiang Li Chuanyue Wang Huiyao Wang Xiaojing Li Wanjun Guo Xun Hu Yang Tian Xiaohong Ma Jeremy Coid Dai Zhang Chao Chen Tao Li Chinese Antipsychotics Pharmacogenomics Consortium 2019Neuroscience Bulletin2019,35,6:3
13Studies on photoprotective mechanism of desert plant Reaumuria soongorica under progressive soil drying显示文摘Reaumuria soongorica (pall.) Maxim, a perennial desert semi-shrub, is widely found in semi-arid areas of China. It shows strong tolerance to drought, high temperature and intense radiation in its natural habitat. In the present study, photoprotective mechanism of R. soongorica was investigated by analyzing diurnal variations of gas exchange and chlorophyll fluorecence parameters during progressive soil drying. The results show that leaf water potential of R. soongorica decreased when the soil water content dropped. Diurnal patterns of net photosynthetic rate (Pn) changed from 'two peaks' to 'one peak' under drought stress, and the leaf water use efficiency (WUE) increased under moderate drought and declined under severe drought. Pn , the primary maximum photochemical efficiency of PSII (Fv/Fm) and the quantum efficiency of non-cyclic electron transport of PSII (ΦPSII) decreased obviously at noon, and showed a photoinhibition phenomenon. But, the non-photochemical quenching of fluorescence (NPQ) soon reached its maximum in the day and then remained almost at the high level until 17:00, indicating that the xanthophylls cycle-dependent thermal energy dissipation played an important role. Diurnal variations of the original chlorophyll fluorescence (Fo) increased at first and then decreased. The increased value of F o under drought stress indicates that there was a reversible inactivation of PSII reaction center. These results indicate that the photoprotective mechanism in R. soongorica was the photoinhibition by using both the xanthophylls cycle-dependent thermal energy dissipation and the reversible inactivation of PSII reaction center under drought stress.YuBing Liu MeiLing Liu HuiJuan Tan Jin Wang ShengHui Zhou 2010Research in Cold and Arid Regions2010,2,3:1
14Paclitaxel liposome for injection (Lipusu) plus cisplatin versus gemcitabine plus cisplatin in the first-line treatment of locally advanced or metastatic lung squamous cell carcinoma: A multicenter, randomized, open-label, parallel controlled clinical study显示文摘Background:Lipusu is the first commercialized liposomal formulation of pacli-taxel and has demonstrated promising efficacy against locally advanced lung squamous cell carcinoma(LSCC)in a small-scale study.Here,we conducted a multicenter,randomized,phase 3 study to compare the efficacy and safety of cis-platin plus Lipusu(LP)versus cisplatin plus gemcitabine(GP)as first-line treat-ment in locally advanced or metastatic LSCC.Methods:Patients enrolled were aged between 18 to 75 years,had locally advanced(clinical stage IIIB,ineligible for concurrent chemoradiation or surgery)or metastatic(Stage IV)LSCC,had no previous systemic chemother-apy and at least one measurable lesion as per the Response Evaluation Criteria in Solid Tumors(version 1.1)before administration of the trial drug.The primary endpoint was progression-free survival(PFS).The secondary endpoints included objective response rate(ORR),disease control rate(DCR),overall survival(OS),and safety profiles.To explore the possible predictive value of plasma cytokines for LP treatment,plasma samples were collected from the LP group at baseline and first efficacy evaluation time and were then subjected to analysis by 45-Plex ProcartaPlex Panel 1 to detect the presence of 45 cytokines using the Luminex xMAP technology.The correlation between treatment outcomes and dynamic changes in the levels of cytokines were evaluated in preliminary analyses.Results:The median duration of follow-up was 15.4 months.237 patients in the LP group and 253 patients in the GP group were included in the per protocol set(PPS).In the PPS,the median PFS was 5.2 months versus 5.5 months in the LP and GP group(hazard rtio[HR]:1.03,P=0.742)respectively.The median OS was 14.6 months versus 12.5 months in the LP and GP group(HR:0.83,P=0.215).The ORR(41.8%versus 45.9%,P=0.412)and DCR(90.3%versus 88.1%,P=0.443)were also similar between the LP and GP group.A significantly lower proportion of patients in the LP group experienced adverse events(AEs)leading to treatment interruptions(10.9%versus 26.4%,P<0.001)or treatment termination(14.3%versus 23.1%,P=0.011).The analysis of cytokine levels in the LP group showed that low baseline levels of 27 cytokines were associated with an increased ORR,and 15 cytokines were associated with improved PFS,with 14 cytokines,including TNF-a,IFN-y,IL-6,and IL-8,demonstrating an overlapping trend.Conclusion:The LP regimen demonstrated similar PFS,OS,ORR and DCR as the GP regimen for patients with locally advanced or metastatic LSCC but had more favorable toxicity profiles.The study also identified a spectrum of different cytokines that could be potentially associated with the clinical benefit in patients who received the LP regimen.Jie Zhang Yueyin Pan Qin Shi Guojun Zhang Liyan Jiang Xiaorong Dong Kangsheng Gu Huijuan Wang Xiaochun Zhang Nong Yang Yuping Li Jianping Xiong Tienan Yi Min Peng Yong Song Yun Fan Jiuwei Cui Gongyan Chen Wei Tan Aimin Zang Qisen Guo Guangqiang Zhao Ziping Wang Jianxing He Wenxiu Yao Xiaohong Wu Kai Chen Xiaohua Hu Chunhong Hu Lu Yue Da Jiang Guangfa Wang Junfeng Liu Guohua Yu Junling Li Jianling Bai Wenmin Xie Weihong Zhao Lihong Wu Caicun Zhou 2022Cancer Communications2022,42,1:1
15Physiological responses and adjustment mechanisms of the dominate species of natural vegetation of Eastern Tengger Desert显示文摘Reaumuria soongorica and Salsola passerina have significant differences in ecophysiological characteristics, which change with the environmental variations. Although they live together for a long period of time, their adaptive mechanisms to environmental stresses are very different. As two extreme xerophytes, Reaumuria soongorica and Salsola passerina differ significantly from other psammophytes in ecophysiological characteristics; they can survive in lower water potential, and can even grow in piedmont areas. Low water potential may be related to the existence of osmosis-regulating substance, such as praline, which can strengthen the capacity of water absorption. Compared to other psammophytes, Reaumuria soongorica and Salsola passerina have a higher degree of photo-inhibition under the same condition, and the photo-inhibition can lead to destruction of the photosynthetic pigment, nevertheless, this photo-inhibition can be repaired under suitable conditions in the morning and evening.HaiYan Zhou HuiJuan Tan ZhiShan Zhang XiaoHong Jia HengWen Fan JianLi Yuan 2010Research in Cold and Arid Regions2010,2,5:1

17Nickel effects on growth and antioxidative enzymes activities in desert plant Zygophyllum xanthoxylon (Bunge) Maxim显示文摘One-month old Zygophyllum xanthoxylon seedlings were grown under five different Ni concentrations (0, 50, 150, 450 and 900 mg/kg). Growth parameters, tissues Ni accumulation, soluble protein content, photosynthetic pigment content, lipid peroxidation, antioxidative enzyme activities, and proline content were studied after one month of Ni exposure. The significant reduction in fresh biomass in the shoot and roots was detected at high Ni concentrations (≥450 mg/kg), whereas dry biomass was not significantly affected in both organs by any of the Ni doses tested. The Ni contents in the shoots and roots increased in a dose-dependent manner, and Ni contents in roots were higher than that in shoots at all treatments. The high Ni doses elevated soluble protein contents in leaves and roots. No visible symptoms of chlorosis were observed in leaves of plants grown in presence of Ni. Malondialdehyde (MDA) contents significantly increased in leaves and roots at high Ni treatments (≥450 mg/kg), indicating that Ni induces oxidative stress. Enzyme activities might play a central role in cellular protection against the Ni induced oxidative stress. Proline contents proportionally increased with the elevated Ni concentrations. Zygophyllum xanthoxylon revealed moderate Ni tolerance under tested culture conditions, and could be used as tools for revegetation for erosion control in moderate Ni contaminated sites.YanLu XinRong Li MingZhu He ZhengNing Wang HuiJuan Tan 2010Research in Cold and Arid Regions2010,2,5:0
18China's Wind Power Integration and Benefits to Energy Saving and Emission Reduction显示文摘Based on the research of wind power development policies, this paper put forward the reform directions to improve the disadvantages of the policies. The wind power’s grid integration status quo is introduced, and the bottle neck of grid integration is analyzed. By the study on the economic benefits of wind power integration in China’s present stage, the results indicate that the wind power industry is in good condition of profits and the profits are higher with the increase of the wind resources in the areas. Through expanding the difference of the power purchase prices in different resource areas, it is beneficial for the nationwide harmonious development of wind power. At last, the present and future benefits of the energy conservation and emission reduction from wind power integration are estimated, which shows that the environmental benefits of 'wind-thermal exchange' will be more and more outstanding along with the expansion of the scale of wind power.Song Yihang, Tan Zhongfu and Zhang Huijuan Institute of Energy Economics and Environment, North China Electric Power University Li Yuan 2011Electricity2011,22,5:0

20An ubiquitin-like protein SDE2 negatively affects sucrose-induced anthocyanin biosynthesis in Arabidopsis显示文摘Anthocyanin biosynthesis is regulated by a conserved transcriptional MBW complex composed of MYB,b HLH and WD40 subunits. However, molecular mechanisms underlying transcriptional regulation of these MBW subunits remain largely elusive. In this study, we isolated an Arabidopsis mutant that displays a constitutive red color in aboveground tissues with retarded growth phenotypes. In the presence of sucrose, the mutant accumulates more than 3-fold anthocyanins of the wild type(WT), but cannot produce anthocyanins as WT in the absence of sucrose. Map-based cloning results demonstrated that the mutation occurs in the locus At4 G01000, which encodes a conserved nuclear-localized ubiquitin-like(UBL) superfamily protein, silencing defective 2(SDE2), in eukaryotes. SDE2 is ubiquitously expressed in various tissues. In the sucrose-induced anthocyanin biosynthesis, SDE2 expression was not responded to sucrose treatment at the early stage but was enhanced at the late stage. SDE2 mutations result in upregulation of anthocyanin biosynthetic and regulatory genes. Yeast-two hybrid analysis indicated that SDE2 has no direct interaction with the MYB transcription factor PAP1 and b HLH factor TT8, indicating that SDE2 is a indirect factor to affect anthocyanin accumulation. Taking together, our data suggest that SDE2 may play a role in finely coordinating anthocyanin biosynthesis with other biological processes.Ye Xie Yulei Zhao Huijuan Tan Qin Chen Jirong Huang 2017Science Bulletin2017,62,23:0
