| 1 | Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration. | Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen | 2019 | National Science Review2019，6，4： | 21 |
| 2 | In vitro culture and differentiation of rat embryonic midbrain-derived neural stem cells显示文摘BACKGROUND:Midbrain-derived neural stem cells (mNSCs) can differentiate into functional mature dopaminergic neurons. The mNSCs are considered the ideal choice for cell therapy of Parkinson’s disease. OBJECTIVE: To isolate rat embryonic mNSCs and to observe the differentiation characteristics of mNSCs induced by cell growth-promoting factors. DESIGN,TIME AND SETTING: An in vitro cell culture study based on the molecular biology of nerve cells was carried out at the Institute of Clinical Medicine,China-Japan Friendship Hospital (China) from March to November 2007. MATERIALS: Sprague Dawley rats at embryonic day 14 were used in this study. Nestin antibody,β-Ⅲ tubulin antibody,glial fibrillary acidic protein (GFAP) antibody and cyclic nucleotide 3’-phosphohydrolase (CNPase) antibody were provided by Abcam; DMEM/F12 medium and N2 supplement were provided by In-vitrogen; epidermal growth factor (EGF) and fibroblast growth factor-2 (FGF2) were provided by R&D Sys-tems. METHODS: The ventral mesencephalon was dissected from embryonic day 14 rat embryos. By trypsin di-gestion and mechanical separation,the brain tissue was triturated into a fine single-cell suspension. The cells were cultured in 5 mL serum-free medium containing DMEM/F12,1% N2 supplement,20 ng/mL EGF and FGF2. The mNSCs at the third generation were coated with 10 μg/mL polylysine and induced to differenti-ate in the DMEM/F12 supplemented with 1% fetal bovine serum and 1% N2. MAIN OUTCOME MEASURES: The neural spheres of the third passage were identified by nestin im-munofluorescence; at the same time,the cells were induced to differentiate,and the types of differentiated cell were identified by immunofluorescence for βⅢ tubulin,GFAP and CNPase. RESULTS: Seven days after primary culture,a great many neurospheres could be obtained by successive pasage. Immunofluorescence assays showed that the neurospheres were nestin positive,and after differentia-tion,the cells expressed GFAP,CNPase and β-Ⅲ-tubulin. CONCLUSION: Embryonic day 14 rat mNSCs can differentiate into neuron-like cells and glial cells fol-lowing induction by EGF,FGF2 and N2 additive. | Xingli Deng Ruen Liu Zhongtang Feng Jing Guo Wu Wang Deqiang Lei Hongyan Li Zhihua Chen | 2008 | Neural Regeneration Research2008，3，11： | 19 |
| 3 | Microstructure and domain engineering of lithium niobate crystal films for integrated photonic applications显示文摘Recently,integrated photonics has attracted considerable interest owing to its wide application in optical communication and quantum technologies.Among the numerous photonic materials,lithium niobate film on insulator(LNOI)has become a promising photonic platform owing to its electro-optic and nonlinear optical properties along with ultralow-loss and high-confinement nanophotonic lithium niobate waveguides fabricated by the complementary metal-oxide-semiconductor(CMOS)-compatible microstructure engineering of LNOI.Furthermore,ferroelectric domain engineering in combination with nanophotonic waveguides on LNOI is gradually accelerating the development of integrated nonlinear photonics,which will play an important role in quantum technologies because of its ability to be integrated with the generation,processing,and auxiliary detection of the quantum states of light.Herein,we review the recent progress in CMOS-compatible microstructure engineering and domain engineering of LNOI for integrated lithium niobate photonics involving photonic modulation and nonlinear photonics.We believe that the great progress in integrated photonics on LNOI will lead to a new generation of techniques.Thus,there remains an urgent need for efficient methods for the preparation of LNOI that are suitable for large-scale and low-cost manufacturing of integrated photonic devices and systems. | Dehui Sun Yunwu Zhang Dongzhou Wang Wei Song Xiaoyan Liu Jinbo Pang Deqiang Geng Yuanhua Sang Hong Liu | 2020 | Light(Science & Applications)2020，9，1： | 7 |
| 4 | CO_2 efflux from different forest soils and impact factors in Dinghu Mountain, China显示文摘CO2 fluxes from soils and related environmental factors were measured in three forest ecosystems of Dinghu Mountain using static chamber-gas chromatograph technique for one year. The seasonal pattern of CO2 flux, contribution of litter on total CO2 flux and the correlations of CO2 flux with soil temperature and soil water content were examined for each type of forest. The results were given as followings: (1) The seasonal patterns of CO2 flux from soil of the three types of forest were similar, with a higher CO2 flux in rainy season than in dry season. The comparative relations of mean annual CO2 fluxes between the three sites were expressed as:monsoon forest > mixed forest > pine forest. (2) CO2 fluxes from litter decomposition in monsoon forest, mixed forest and pine forest accounted for 24.43%, 41.75% and 29.23% of the corresponding total CO2 fluxes from forest floor, respectively. (3) Significant relationships were found between CO2 fluxes and soil temperatures at 5 cm depth for the three types of forest, which could be best described by exponential equations. The calculated Q10 values based on soil temperature at 5 cm depth ranged from 1.86 to 3.24. More significant relationships were found between CO2 fluxes and soil water content when the annual variation coefficients of soil moisture were higher. | ZHOU Cunyu, ZHOU Guoyi, ZHANG Deqiang, WANG Yinghong & LIU Shizhong Dinghushan Forest Ecosystem Research Station, Chinese Academy of Sciences, Guangzhou 510650, China Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China | 2005 | Science China Earth Sciences2005，48，z1： | 6 |
| 5 | Effect of calycosin on left ventricular ejection fraction and angiogenesis in rat models with myocardial infarction显示文摘OBJECTIVE:To evaluated the effect of calycosin on left ventricular ejection fraction and angiogenesis.METHODS:Adult male Sprague-Dawley rats were randomly assigned into calycosin-treated groups(0.5,1,2,and 4 mg/kg qd),a dimethyl sulfoxide(DMSO),or a sham-operated control group.The myocardial ischaemia(Ml) model was intraperitoneally administered calycosin for 28 days.The survival rates and left ventricular ejection fractions(LVEF)were compared between groups.The expression levels of vascular endothelial growth factor(VEGF)and cluster of differentiation 31(CD31) in ischaemic myocardium were also measured and compared.RESULTS:The construction of MI model resulted in a LVEF reduction of 50% compared with the sham-control.After 28 days,the LVEF value was 10% higher when calycosin(4 mg/kg) was administered compared with the DMSO group.The expression of VEGF and CD31 showed a dose-dependent manner when calycosin was administrated.The calycosin-treated(4 mg/kg) group displayed a twofold increase in VEGF expression at both the mRNA and protein levels compared with the DMSO group.In addition,CD31 expression in the microvascular increased 1.5-fold in the 4 mg/kg calycosin-treated group.CONCLUSION:Calycosin improved left ventricular ejection fraction in the MI rat models,induced VEGF expression in the ischaemic myocardium,increased CD31 expression and promoted angiogenesis. | Gao Junqing Chen Tao Jin Huigen Liu Zongjun Zhao Deqiang | 2015 | Journal of Traditional Chinese Medicine2015，35，2： | 6 |
| 6 | Effects of precipitation on soil organic carbon fractions in three subtropical forests in southern China显示文摘Aims The aim of this study was to investigate the effects of precipitation changes on soil organic carbon(SOC)fractions in subtropical forests where the precipitation pattern has been altered for decades.Methods We conducted field manipulations of precipitation,including ambient precipitation as a control(CK),double precipitation(DP)and no precipitation(NP),for 3 years in three forests with different stand ages(broadleaf forest[BF],mixed forest[MF]and pine forest[PF])in subtropical China.At the end of the experiment,soil samples were collected to assay SOC content,readily oxidizable organic carbon(ROC)and non-readily oxidizable organic carbon(NROC),as well as soil microbial biomass carbon(MBC),pH and total nitrogen content.Samples from the forest floors were also collected to analyze carbon(C)functional groups(i.e.alkyl C,aromatic C,O-alkyl C and carbonyl C).Furthermore,fine root biomass was measured periodically throughout the experiment.Important Findings Among the forests,ROC content did not exhibit any notable differences,while NROC content increased significantly with the stand age.This finding implied that the SOC accumulation observed in these forests resulted from the accumulation of NROC in the soil,a mechanism for SOC accumulation in the mature forests of southern China.Moreover,NP treatment led to significant reductions in both ROC and NROC content and therefore reduced the total SOC content in all of the studied forests.Such decreases may be due to the lower plant-derived C inputs(C quantity)and to the changes in SOC components(C quality)indicated by C functional groups analyses under NP treatment.DP treatment in all the forests also tended to decrease the SOC content,although the decreases were not statistically significant with the exception of SOC and ROC content in PF.This finding indicated that soils in MF and in BF may be more resistant to precipitation increases,possibly due to less water limitations under natural conditions in the two forests.Our results therefore highlight the different responses of SOC and its fractions to precipitation changes among the forests and suggest that further studies are needed to improve our understanding of SOC dynamics in such an important C sink region. | Xiaomei Chen Deqiang Zhang Guohua Liang Qingyan Qiu Juxiu Liu Guoyi Zhou Shizhong Liu Guowei Chu Junhua Yan | 2016 | Journal of Plant Ecology2016，9，1： | 4 |
| 7 | Reduced turnover rate of topsoil organic carbon in old-growth forests:a case study in subtropical China显示文摘Background:Old-growth forests are irreplaceable with respect to climate change mitigation and have considerable carbon(C)sink potential in soils.However,the relationship between the soil organic carbon(SOC)turnover rate and forest development is poorly understood,which hinders our ability to assess the C sequestration capacity of soil in old-growth forests.Methods:In this study,we evaluated the SOC turnover rate by calculating the isotopic enrichment factor β(defined as the slope of the regression between ^(13)C natural abundance and log-transformed C concentrations)along 0-30 cm soil profiles in three successional forests in subtropical China.A lower β(steeper slope)is associated with a higher turnover rate.The three forests were a 60-year-old P.massoniana forest(PF),a 100-year-old coniferous and broadleaved mixed forest(MF),and a 400-year-old monsoon evergreen broadleaved forest(BF).We also analyzed the soil physicochemical properties in these forests to examine the dynamics of SOC turnover during forest succession and the main regulators.Results:The β value for the upper 30-cm soils in the BF was significantly(p<0.05)higher than that in the PF,in addition to the SOC stock,although there were nonsignificant differences between the BF and MF.The β value was significantly(p<0.05)positively correlated with the soil recalcitrance index,total nitrogen,and available nitrogen contents but was significantly(p<0.01)negatively correlated with soil pH.Conclusions:Our results demonstrate that SOC has lower turnover rates in old-growth forests,accompanied by higher soil chemical recalcitrance,nitrogen status,and lower soil pH.This finding helps to elucidate the mechanism underlying C sequestration in old-growth forest soils,and emphasizes the important value of old-growth forests among global C sinks. | Xin Xiong Juxiu Liu Guoyi Zhou Qi Deng Huiling Zhang Guowei Chu Ze Meng Deqiang Zhang | 2021 | Forest Ecosystems2021，8，4： | 4 |
| 8 | Changes in leaf nutrient traits and photosynthesis of four tree species: effects of elevated [CO_(2)], N fertilization and canopy positions显示文摘Aims Leaf traits of trees exposed to elevated[CO_(2)]in association with other environmental factors are poorly understood in tropical and subtropical regions.Our goal was to investigate the impacts of elevated[CO_(2)]and N fertilization on leaf traits in southern China.Methods Four tree species,Schima superba Gardn.et Champ.(S.superba),Ormosia pinnata(Lour.)Merr(O.pinnata),Castanopsis hystrix AC.DC.(C.hystrix)and Acmena acuminatissima(Blume)Merr.et Perry(A.acuminatissima)were studied in a factorial combination of atmospheric[CO_(2)](ambient at~390μmol mol^( -1)and elevated[CO_(2)]at~700μmol mol ^(-1))and N fertilization(ambient and ambient+100 kg N ha ^(-1)year^( -1))in open-top chambers in southern China for 5 years.Leaf mass per unit leaf area(LMA),leaf nutrient concentration and photosynthesis(A_(sat))were measured.Important Findings Results indicated that leaf traits and photosynthesis were affected differently by elevated[CO_(2)]and N fertilization among species.Elevated[CO_(2)]decreased LMA in all species,while N fertilization did not affect LMA.Leaf mass-based N concentration(N_(M))was significantly greater in O.pinnata and C.hystrix grown in elevated[CO_(2)]but was lower in S.superba.Leaf mass-based P concentration(P_(M))was significantly greater in C.hystrix and A.acuminatissima exposed to elevated[CO_(2)]but was lower in S.superba.N fertilization significantly increased P_(M) in O.pinnata but decreased P_(M) in S.superba.Photosynthetic stimulation in O.pinnata,C.hystrix and A.acuminatissima was sustained after 5 years of CO_(2)fumigation.N fertilization did not modify the effects of elevated[CO_(2)]on photosynthesis.Leaf traits(N_(M),N_(A),P_(M),P_(A))and light-saturated photosynthesis were decreased from the upper to lower canopy.Canopy position did not alter the responses of leaf traits and photosynthesis to elevated[CO_(2)].Results suggest that photosynthetic stimulation by elevated[CO_(2)]in native species in subtropical regions may be sustained in the long term. | Juxiu Liu Deqiang Zhang Guoyi Zhou Honglang Duan | 2012 | Journal of Plant Ecology2012，5，4： | 4 |
| 9 | Comparison of Nonlinear Local Lyapunov Vectors with Bred Vectors, Random Perturbations and Ensemble Transform Kalman Filter Strategies in a Barotropic Model显示文摘The breeding method has been widely used to generate ensemble perturbations in ensemble forecasting due to its simple concept and low computational cost. This method produces the fastest growing perturbation modes to catch the growing components in analysis errors. However, the bred vectors(BVs) are evolved on the same dynamical flow, which may increase the dependence of perturbations. In contrast, the nonlinear local Lyapunov vector(NLLV) scheme generates flow-dependent perturbations as in the breeding method, but regularly conducts the Gram–Schmidt reorthonormalization processes on the perturbations. The resulting NLLVs span the fast-growing perturbation subspace efficiently, and thus may grasp more components in analysis errors than the BVs.In this paper, the NLLVs are employed to generate initial ensemble perturbations in a barotropic quasi-geostrophic model.The performances of the ensemble forecasts of the NLLV method are systematically compared to those of the random perturbation(RP) technique, and the BV method, as well as its improved version—the ensemble transform Kalman filter(ETKF)method. The results demonstrate that the RP technique has the worst performance in ensemble forecasts, which indicates the importance of a flow-dependent initialization scheme. The ensemble perturbation subspaces of the NLLV and ETKF methods are preliminarily shown to catch similar components of analysis errors, which exceed that of the BVs. However, the NLLV scheme demonstrates slightly higher ensemble forecast skill than the ETKF scheme. In addition, the NLLV scheme involves a significantly simpler algorithm and less computation time than the ETKF method, and both demonstrate better ensemble forecast skill than the BV scheme. | Jie FENG Ruiqiang DING Jianping LI Deqiang LIU | 2016 | Advances in Atmospheric Sciences2016，33，9： | 3 |
| 10 | Visualizing DC morphology and T cell motility to characterize DC-T cell encounters in mouse lymph nodes under mTOR inhibition显示文摘Mammalian target of rapamycin(mTOR),a serine/threonine kinase orchestrating cellular metabolism,is a crucial immune system regulator.However,it remains unclear how mTOR regulates dendritic cell(DC) function in vivo,especially DC-T cell encounters,a critical step for initiating adaptive immune responses.We dynamically visualized DC-T contacts in mouse lymph node using confocal microscopy and established an encounter model to characterize the effect of mTOR inhibition on DC-T cell encounters using DC morphology.Quantitative data showed mTOR inhibition via rapamycin altered DC shape,with an increased form factor(30.17%) and decreased cellular surface area(20.36%) and perimeter(22.43%),which were associated with Cdc42 protein downregulation(52.71%).Additionally,DCs adopted a similar morphological change with Cdc42 inhibition via ZCL278 as that observed with mTOR inhibition.These morphologically altered DCs displayed low encounter rates with T cells.Time-lapse imaging data of T cell motility supported the simulated result of the encounter model,where antigen-specific T cells appeared to reduce arrest in the lymph nodes of rapamycin-pretreated mice relative to the untreated group.Therefore,mTOR inhibition altered DC morphology in vivo and decreased the DC-T cell encounter rate,as well as Cdc42 inhibition.By establishing an encounter model,our study provides an intuitive approach for the early prediction of DC function through morphological quantification of form factor and area. | Qiaoya Lin Zheng Liu Meijie Luo Hao Zheng Sha Qiao Chenlu Han Deqiang Deng Zhan Fan Yafang Lu Zhihong Zhang Qingming Luo | 2019 | Science China(Life Sciences)2019，62，9： | 2 |
| 11 | Transparent organic light-emitting diodes based on Cs_2 CO_3:Ag/Ag composite cathode显示文摘The transparent organic light-emitting diodes (TOLEDs) based on Cs 2 CO 3:Ag/Ag composite cathode are reported in this paper.They show higher efficiency and better stability than the control devices with the Cs 2 CO 3 /Ag cathode.The devices are highly transparent,and show total efficiencies from both sides of the devices comparable with conventional bottom-emitting devices.The electroluminescence (EL) spectrum from the cathode side of the device is closer to the photoluminescence (PL) spectrum of the light-emitting material than that from the anode side.The effect of the cathode Ag thickness on the device performance has been investigated.It is observed that a critical Ag thickness of 15 nm is required to form a good Ag film with high optical transparency and electrical conductivity. | LIU Qian DUAN Lian ZHANG DeQiang QIAO Juan WANG LiDuo DONG GuiFang QIU Yong | 2010 | Chinese Science Bulletin2010，55，15： | 2 |
| 12 | 中国西南地区2007年-2011年男性乳腺癌发生率(英文)显示文摘Objective: Male breast cancer is a rare disease with an incidence of about 1% of breast cancers in USA, but relatively lack of the information of male breast cancer in China, especially in Southwest of China, led us to study its incidence trends. Methods: Chongqing is one of the biggest and the most important areas that is located in Southwest of China. There are around 31.4 million people who live in approximate 82 402.95 km2area of Chongqing. Data about breast cancer patients registered in the Center for Disease Prevention and Control of Chongqing(China) were statistically collected from 187 hospitals, about 58 hospitals in city and 129 hospitals in country, and over 6.2 million people were studied every year. It was tried to represent all the people in villages and cities in Chongqing, China. Results: The incidence of male breast cancer in Southwest of China ranged from 0.34/100 000 to 1.45/100 000 between 2007 and 2011, while the incidence of female breast cancer ranged from 15.40/100000 to 21.66/100000 at the same time. The rate of male breast cancer to female breast cancer ranged from 0.02:1 to 0.07:1, male breast cancer accounted for 1.96% to 6.5%(with the mean value of 2.9%) of breast cancers in Southwest of China from 2007 to 2010. Conclusion: In Southwest of China male breast cancer accounts for about 2.9% of breast cancers which is higher than that in United States. It is important for policy makers and health manager to seriously consider breast cancer in future plan in Southwest of China. | Liangbin Jin Linjie Lu Lingquan Kong Yang Bai Zixiang Yao Guangyan Ji Shengchun Liu Guosheng Ren Kainan Wu Hua Tang Deqiang Mao | 2013 | The Chinese-German Journal of Clinical Oncology2013，12，11： | 2 |

| 18 | New hybrid encapsulation for flexible organic light-emitting devices on plastic substrates显示文摘The hybrid encapsulation for flexible organic light-emitting devices on plastic substrate was investi- gated. The hybrid encapsulation consisted of four periods of Alq3/LiF layers as the pre-encapsulation layer and a flexible aluminum foil coated with getter as the encapsulation cap. We measured the device lifetime at a continuous constant current of 20 mA/cm2, which corresponded to an initial luminance of 2000 cd/m2. The half-luminance decay time of the encapsulated device was about 458 h. More over, the hybrid encapsulation is ultrathin and flexible, ensuring device bendability. | LIU Song ZHANG DeQiang LI Yang DUAN Lian DONG GuiFang WANG LiDuo QIU Yong | 2008 | Chinese Science Bulletin2008，53，6： | 1 |
| 19 | Water-use efficiency of four native trees under CO_(2) enrichment and N addition in subtropical model forest ecosystems显示文摘Aims We aimed to evaluate the changes in water-use efficiency(WuE)in native tree species in forests of subtropical China,and determine how coexisting species would be responding to increases in atmospheric carbon dioxide(CO_(2))concentrations and nitrogen(N)deposition.Methods We used model forest ecosystems in open-top chambers to study the effects of elevated CO_(2)(ca.700μmol mol−1)alone and together with N addition(NH4No3 applied at 100 kg N ha−1year−1)on WuE of four native tree species(Schima superba,Ormosia pin-nata,Castanopsis hystrix and Acmena acuminatissima)from 2006 to 2010.Important findingsour result indicated that all species increased their WuE when they were exposed to elevated CO_(2).although higher WuE was shown in faster-growing species(S.superba and O.pinnata)than that of slower-growing species(C.hystrix and Acmena acuminatissima),the increased extent of WuE induced by elevated CO_(2) was higher in the slower-growing species than that of the faster-growing species(P<0.01).the N treatment decreased WuE of S.superba,while the effects on other species were not significant.the interactions between elevated CO_(2) and N addition increased intrinsic WuE of S.superba significantly(P<0.001),however,it did not affect WuE of the other tree species significantly.We conclude that the responses of native tree species to elevated CO_(2) and N addition are different in subtropical China.the species-specific effects of elevated CO_(2) and N addition on WuE would have important implications on species composition in China’s subtropics in response to global change. | Yiyong Li Juxiu Liu Genyun Chen Guoyi Zhou Wenjuan Huang Guangcai Yin Deqiang Zhang Yuelin Li | 2015 | Journal of Plant Ecology2015，8，4： | 1 |
