| 1 | Heavy metal accumulation by panicled goldenrain tree(Koelreuteria paniculata) and common elaeocarpus(Elaeocarpus decipens) in abandoned mine soils in southern China显示文摘Phytoremediation can be used as a sustainable technology for mine spoil remediation to remove heavy metals.This study investigated the concentration of 7 heavy metal contamination in soil and plant samples at an abandoned mine site.We found that,after vegetation remediation at the abandoned mine site,the reduction rates for 7 heavy metals were in the range of 4.2%-86%,where reduction rates over 50% were achieved for four heavy metals(Zn,Mn,Cd,Ni).Transfer coeffcients of the panicled goldenrain tree(Koelreuteria paniculata Laxm) and the common elaeocarpus(Elaeocarpus decipens) for Zn,Mn,Ni,and Co were more than 1.Enrichment coeffcients of both trees for Mn were higher than 1.Our results suggest that the panicled goldenrain tree and the common elaeocarpus tree may act as accumulators in remediation.Moreover,the woody vegetation remediation in abandoned mining areas play an important role in improving scenery besides removing heavy metal from contaminated soil. | TIAN Dalun ZHU Fan YAN Wende Fang Xi XIANG Wenhua DENG Xiangwen WANG Guangjun PENG Changhui | 2009 | Journal of Environmental Sciences2009，21，3： | 11 |
| 2 | Impacts of changed litter inputs on soil CO_2 efflux in three forest types in central south China显示文摘Climate change is expected to cause the alteration of litter production in forests,which may result in substantial changes in soil CO2 efflux (FCO2) process as litter represents a major pathway of carbon from vegetation to the soils.In this study,we conducted an aboveground litter manipulation experiment to examine the influence of litter addition and exclusion on soil FCO2 in Camphor tree,Masson pine,and mixed Camphor tree and Masson pine forests in central south China.Litter input manipulation included three treatments:non-litter input (litter exclusion),double litter input (litter addition),and natural litter input (control).On average,litter exclusion significantly reduced soil FCO2 rate by approximately 39%,24% and 22% in Camphor tree forests,the Mixed forests,and Masson pine forests,respectively.On a yearly basis,double litter addition significantly increased soil CO2 by 12% in the Mixed forests (P=0.02) but not in both Camphor tree and Masson pine forests (P>0.05),when compared with their corresponding control treatments.However,litter addition increased soil FCO2 rates in the months of June-August in Camphor tree and Masson pine forests,coinciding with high soil temperature of summer conditions.Litter exclusion reduced soil FCO2 more than litter addition increased it in the study sites.Responses of soil respiration to litter input treatments varied with forest types.Litter input treatments did not alter the seasonal patterns of soil temperature and soil water content.Our results indicated that changes in aboveground litter as a result of global climate change and/or forest management have a great potential to alter soil respiration and soil carbon balance in forest ecosystems. | YAN WenDe CHEN XiaoYong TIAN DaLun PENG YuanYing WANG GuangJun ZHENG Wei | 2013 | Science China(Technological Sciences)2013，56，3： | 11 |
| 3 | Response of soil respiration to nitrogen addition in two subtropical forest types显示文摘Anthropogenic activities have increased nitrogen(N)deposition in terrestrial ecosystems,which directly and indirectly affects soil biogeochemical processes,including soil respiration.However,the effects of the increases in N availability on soil respiration are not fully understood.In this study,soil respiration was measured using an infrared gas analyzer system with soil chambers under four N treatments(0,5,15,and 30 g Nm^-2 year^-1 as control,low N(LN),moderate N(MN),and high N(HN),respectively)in camphor tree and slash pine forests in subtropical China.Results showed that soil respiration rates decreased by 37% in the camphor tree forest and 27% in the slash pine forest on average on an annual base,respectively,in the N-fertilized treatments when compared with the control.No significant differences were found in the soil respiration rate among the LN,MN,and HN treatments in both forest types as these fertilized plots reached an adequate N content zone.In addition,soil microbial biomass carbon(C)content and fine root biomass declined in N-treated plots compared to the control.Our results indicated that elevated N deposition might alter the tree growth pattern,C partitioning,and microbial activity,which further affect soil C sequestration by reducing soil respiration in subtropical forests of China. | Wende YAN Xiaoyong CHEN Yuanying PENG Fan ZHU Wei ZHEN Xuyuan ZHANG | 2020 | Pedosphere2020，30，4： | 6 |
| 4 | Mathematical model study on the damage of the liquid phase to productivity in the gas reservoir with a bottom water zone显示文摘The production process in the gas reservoir with an aquifer is complex.With gas production,aquifer water could possibly flow into the production well and accumulate within the well bore,which leads to a lower production rate and may even block the producer.However,few studies in the literature investigate the damage caused by the liquid phase in this kind of reservoir or predict gas productivity using the relationship between reservoir pressure and water gas ratio(WGR).For this reason,it is important to know the effects of the formation of liquid phase behavior on production when an aquifer is present under a gas reservoir.From the results of published literature reviews,we found that studies focused on the production of a gas reservoir with bottom water.Nevertheless,for gas well damage from the liquid phase behavior,we found that there was no statistical data or mathematical model of the relationship between reservoir pressure and the gas oil ratio(GOR),which affects production.In this research,based on the theory of fluid flow in porous media,a new mathematical model of water and gas production and a new equation on gas well productivity is developed.To verify the model and equation,gas production data collected from the field are applied.By analyzing the typical gas reservoir with bottom water and the collected data,influences from the liquid phase behavior are shown.In this way,mathematical relationships between reservoir pressure and the WGR and between the GOR and production decline were obtained.The new gas productivity model is derived from the gas and water pseudo pressure functions,which can be applied to analyze well damage caused by the liquid phase.In order to verify the mathematical model,production data were collected from a typical gas reservoir with an aquifer located in the Changxing gas reservoir.The results indicate that a semi-logarithmic linear relationship is obtained between the WGR and productivity decrease.When the WGR increases from 0.5 to 15m3/104m3,damage caused by liquid phase decreases to 59%.The tendency of gas productivity in the Changxing gas reservoir was obtained so that it decreases as reservoir pressure decreases and increases as the WGR decreases.The gradient of the gas productivity deduction increases as the WGR increases.By the end of the data analysis,two linear equations indicating the relationship between gas productivity and reservoir pressure and the relationship between gas productivity and the water gas ratio are obtained:QAOF?A1lnWGRB1 and QAOF?A2lnPB2,respectively. | Xiaoliang Huang Xiao Guo Xinqian Lu Xiang Zhou Zhilin Qi Wende Yan Jiqiang Li | 2018 | Petroleum2018，4，2： | 4 |
| 5 | Soil respiration dynamics in Cinnamomum camphora forest and a nearby Liquidambar formosana forest in Subtropical China显示文摘Climate change can significantly affect carbon cycling of forest ecosystems.The diurnal and seasonal dynamics of soil respiration (Rs) in Cinnamomum camphora and Liquidambar formosana forests were investigated by using infrared gas exchange analyzer of Li-Cor 6400-09 each month in 2006.Soil temperature and moisture were also measured.Diurnal variations in Rs varied with daily soil temperature in the two forests.Across the growing season,soil respiration peaked on July 28 due to higher soil temperature and moisture conditions.Seasonal Rs variations were predominantly influenced by soil temperature.Seasonal soil respirations in C.camphora and L.formosana forests were strongly related to soil temperature (x) at 5-cm depth (Rs=0.1598e 0.1377x (R 2=0.9289,P=0.001) and Rs=0.2177e 0.0962x (R 2=0.927,P=0.000)),while annual mean Rs rate was 2.614 and 1.397 μmol m-2 s-1 and Q 10 values were 3.96 and 2.62 for the two forests,respectively.However,Rs was not influenced by seasonal changes in soil moisture (w) in the two forests in 2006.We developed two equations (Rs=-0.020w 2 +0.497w+0.562 (R 2=0.109,P>0.05),Rs=-0.001w 2 +0.072w +0.731(R 2=0.053,P>0.05)) to describe the relationship between Rs and soil moisture.A positive relationship between Rs and soil moisture were observed when soil moisture was below 12.43% and 18.00%,but when soil moisture exceeded threshold values of 12.43% and 18.00%,soil moisture became the restraint factor for Rs.Long-term observations of soil respiration and moisture are required to understand the temporal dynamics of soil respiration. | TIAN DaLun WANG GuangJun YAN WenDe XIANG WenHua PENG ChangHui | 2010 | Chinese Science Bulletin2010，55，8： | 2 |

| 9 | Cannabis suppresses antitumor immunity by inhibiting JAK/STAT signaling in T cells through CNR2显示文摘The combination of immune checkpoint blockade(ICB)with chemotherapy significantly improves clinical benefit of cancer treatment.Since chemotherapy is often associated with adverse events,concomitant treatment with drugs managing side effects of chemotherapy is frequently used in the combination therapy.However,whether these ancillary drugs could impede immunotherapy remains unknown.Here,we showed that∆9-tetrahydrocannabinol(THC),the key ingredient of drugs approved for the treatment of chemotherapy-caused nausea,reduced the therapeutic effect of PD-1 blockade.The endogenous cannabinoid anandamide(AEA)also impeded antitumor immunity,indicating an immunosuppressive role of the endogenous cannabinoid system(ECS). | Xinxin Xiong Siyu Chen Jianfei Shen Hua You Han Yang Chao Yan Ziqian Fang Jianeng Zhang Xiuyu Cai Xingjun Dong Tiebang Kang Wende Li Penghui Zhou | 2022 | Signal Transduction and Targeted Therapy2022，7，5： | 1 |
| 10 | 杉木叶片性状不支持广为接受的通量性状网络假说显示文摘“高叶脉密度-更快生长和更高的生产力”模型和假说认为高叶脉密度能促进更高的碳和水的耦合效率,暗示了个体的快速生长和高林分生产力,这些假说被研究者广泛关注和认同。然而,这些模型和假说并没有包括足够的裸子植物样本,特别是在亚热带栽培的针叶树种。我们在此研究了叶脉密度和叶功能性状的值和比例关系,这些样本来自于以快速生长著称的杉木(Cunninghamia lanceolata)的主要分布区。我们还检索了一个经验数据集,该数据集包括杉木的光合作用、生物化学、解剖学和水力特性。杉木叶脉密度(范围为0.34–1.09 mm/mm)远低于全球报道的范围(1–25 mm/mm),而杉木以快速生长和高产在中国长期闻名。我们进一步证实,较高的脉络密度与较小的叶片负相关(r=-0.71,P<0.001),这与被子植物中发现的情况一致。然而,我们发现,与全球物种(正相关)相比,杉木的叶脉密度-叶厚相关性和叶片寿命可塑性呈现相反的趋势,这种关系可能暗示功能效率和生产力间的权衡。我们的结果将为普适的生长规律提供有效的补充评估,包括评价区域植物性状特征、植物物种的配置和性状效率对水力潜能的影响。 | Xi Peng Meifang Zhao Shuguang Liu Wende Yan | 2023 | Journal of Plant Ecology2023，16，2： | 0 |
| 11 | Tripotassium citrate monohydrate derived carbon nanosheets as a competent assistant to manganese dioxide with remarkable performance in the supercapacitor显示文摘Production cost,capacitance,and electrode materials safety are the key factors to be concerned about for supercapacitors.In this work,a type of carbon nanosheets was produced through the carbonization of tripotassium citrate monohydrate and nitric acidification.Subsequently,a well-designed manganese dioxide/carbon nanosheets composite was synthesized through hydrothermal treating.The carbon nanosheets served as the substrate for growing the manganese dioxide,regulating its distribution,and preventing it from inhomogeneous dimensions and severe agglomeration.Many manganese dioxide nanosheets grew vertically on the numerous functional groups generated on the surface of the carbon nanosheets during acidification.The synergistic combination of carbon nanosheets and manganese dioxide tailors the electrochemical performance of the composite,which benefits from the excellent conductivity and stability of carbon nanosheets.The carbon nanosheets derived from tripotassium citrate monohydrate are conducive to the remarkable performance of manganese dioxide/carbon nanosheets electrode.Finally,an asymmetric supercapacitor with active carbon as the cathode and manganese dioxide/carbon nanosheets as the anode was assembled,achieving an outstanding energy density of 54.68 Wh·kg^(−1) and remarkable power density of 6399.2 W·kg^(−1) superior to conventional lead-acid batteries.After 10000 charge-discharge cycles,the device retained 75.3%of the initial capacitance,showing good cycle stability.Two assembled asymmetric supercapacitors in series charged for 3 min could power a yellow light emitting diode with an operating voltage of 2 V for 2 min.This study may provide valuable insights for applying carbon materials and manganese dioxide in the energy storage field. | Wenjing Zhang Xiaoxue Yuan Xuehua Yan Mingyu You Hui Jiang Jieyu Miao Yanli Li Wending Zhou Yihan Zhu Xiaonong Cheng | 2022 | Frontiers of Chemical Science and Engineering2022，16，3： | 0 |
| 12 | Biomass Roasting Reduction of Goethite Ores显示文摘Effective use of low-grade goethite ores in steel industry is necessary to achieve cost reduction and solve the problem of resource shortage. Biomass as heating and reducing agent attract much more attention for utilization in ironmaking process due to its low-carbon, energy-saving, emission-cutting and low-cost. We investigate three types of biomass (corn straw, pine sawdust, rice husk powders) roasting reduction mechanism and the magnetism of the roasting products. Structure analysis indicates that 15% dosage of each biomass mixed with goethite ores roasting at 550-600 °C for 1h could be effectively converted into strong magnetic product, i.e. maghemite (γ-Fe2O3). Weak magnetic separation shows that under the magnetic field of 200 kA/m, goethite ores roasted by 15% of pine sawdust could achieve TFe 61.64% with the recovery of 79.75%, TFe 61.75% with the recovery of 80.16% for roasting with rice husk, and TFe 61.47% with the recovery of 81.28% for roasting with corn straw. | WU Yan LI Yonghuo YANG Xiang XIAO Wending YANG Mei ZHANG Ping BAO Zhengyu | 2013 | 矿物学报2013，33，S1： | 0 |
| 13 | Short-term Effects of Nitrogen Deposition on Soil Respiration of Cinnamomum camphora Plantation显示文摘The nitrogen deposition experiments on Cinnamomum camphora plantation of Hunan provincial botanical garden were simulated from June the 7th to October the 7th,2010,the nitrogen deposition levels was respectively as control(CK, 0 g·m-2 a-1),low nitrogen(LN,5 g·m-2 a-1),medium nitrogen(MN,15 g·m-2 a-1) and high nitrogen(HN, 30 g·m -2 a-1).The soil respiration speed and soil surface temperature and the surface water content of the soil were determined by LI-8100 measuring instrument.The results show that the average values of soil respiration speed were CK (4.09±0.66μmol·m-2 s-1),LN(2.39±029μmol·m-2 s-1), MN(2.18±0.19μmol·m-2s-1),HN (2.28±0.25μmol·m-2 s-1),and the treatment of the CK was obviously higher than the other three treatments(P<0.01).With different nitrogen concentrations deposition treatments,the Q10 (temperature sensitivity coefficients) for soil respiration of CK,LN,MN and HN treatments were 1.84,1.71,1.83 and 1.56.It was positive correlation between the respiration speed and the surface(≤10 cm) temperature of tested soil.It was negative correlation between the respiration speed and the surface(≤5 cm) water content of tested soil(P>0.05).Volumetric water content of 5-cm soil was between 0.266 6-0.294 4(m3·m-3), and the monthly content did not vary too much during the research period(1.8%-9.4%).The findings suggest that the initial stage of nitrogen deposition obviously influenced the soil respiration of C.camphora plantation. | Zhang Xuyuan Yan Wende Ma Xiuhong Zheng Wei Wang Guangjun Liang Xiaocui | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
| 14 | CD146 promotes malignant progression of breast phyllodes tumor through suppressing DCBLD2 degradation and activating the AKT pathway显示文摘Background As a rapid-progressing tumor,breast malignant phyllodes tumors(PTs)are challenged by the lack of effective therapeutic strategies and suitable prognostic markers.This study aimed to clarify the role and mechanism of CD146 on promoting PTs malignant progression,and to identify a novel prognosis marker and treatment target of breast malignant PTs.Methods The expression and prognostic significance of CD146 in PTs was detected through single-cell RNA-sequencing(scRNA-seq),immunostaining,real-time PCR and other methodologies.Functional experiments including proliferation assay,colony formation assay,transwell assay,and collagen contraction assay were conducted to validate the role of CD146 in malignant progression of PTs.The efficacy of anti-CD146 monoclonal antibody AA98 against malignant PTs was corroborated by a malignant PT organoid model and a PT patient-derived xenograft(PDX)model.Transcriptome sequencing,proteomic analysis,co-immunoprecipitation,and pull-down assay was employed to identify the modulating pathway and additional molecular mechanism.Results In this study,the scRNA-seq analysis of PTs disclosed a CD146-positive characteristic in theα-SMA+fibroblast subset.Furthermore,a progressive elevation in the level of CD146 was observed with the malignant progression of PTs.More importantly,CD146 was found to serve as an independent predictor for recurrence in PT patients.Furthermore,CD146 was found to augment the viability and invasion of PTs.Mechanistically,CD146 acted as a protective“shield”to prevent the degradation of Discoidin,CUB,and LCCL domain-containing protein 2(DCBLD2),thereby activating the phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)signaling pathway and enhancing malignant behaviors of PT cells.In the malignant PT organoid and PDX model,a significant suppression of malignant PT growth was observed after the application of AA98.Conclusions These findings suggested that CD146 served as an efficacious marker for predicting PT malignant progression and showed promise as a prognosis marker and treatment target of breast malignant PTs.The study further unveiled the essential role of the CD146-DCBLD2/PI3K/AKT axis in the malignant progression of PTs. | Jiewen Chen Qingji Xu Dan Liu Xun Li Mingyan Guo Xuehui Chen Jianyou Liao Rong Lei Wende Li Hongyan Huang Phei Er Saw Erwei Song Xiyun Yan Yan Nie | 2023 | Cancer Communications2023，43，11： | 0 |
| 15 | Drainage pattern recognition method considering local basin shape based on graph neural network显示文摘Drainage pattern recognition is crucial for geospatial understanding and hydrologic modelling.Currently,drainage pattern recognition methods employ geometric measures of overall and local features of river networks but lack measures of river basin unit shape features,so that potential correlations between river segments are usually ignored,resulting in poor drainage pattern recognition results.In order to overcome this problem,this paper proposes a supervised graph neural network method that considers the local basin unit shape of river networks.First,based on the overall hierarchy of the river networks,the confluence angle of river segments and the shape of river basin units,multiple drainage pattern classification features are extracted.Then,typical drainage pattern samples from the multi-scale NSDI and USGS databases are used to complete the training,validation and testing steps.Experimental results show that the drainage pattern indexes proposed can describe the characteristics of different drainage patterns.The method can effectively sample the adjacent river segments,flexibly transfer the associated pattern features among river segment neighbours,and aggregate the deeper characteristics of the river networks,thus improving the drainage pattern recognition accuracy relative to other methods and reliably distinguishing different drainage patterns. | Wenning Wang Haowen Yan Xiaomin Lu Yi He Tao Liu Wende Li Pengbo Li Fang Xu | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 16 | Phenomenological models of diffusivities based on local composition显示文摘In phenomenological models,diffusivity is at least a function of composition and the diffusivities at infinite dilution.An additional parameter(?),which can be determined by diffusivity in midpoint,are specially brought forward as token of fractional friction related with the interactions of same molecules in this paper,to extrapolate a new correlative equation for the mutual Maxwell-Stefan diffusivities.Furthermore,the correlative equation can be extended to calculate diffusivities in multicomponent mixtures based on binary data alone.The theoretical calculations are evaluated with published experimental data.The M-S diffusivities in a three-component liquid system are regarded as binary coefficients,the predictive results also agree with the experimental data.Results indicate that the model with additional coefficients is superior to currently used Darken methods,especially for systems of polar organic-water and those containing associative component. | YAN Jianmin,XIAO Wende (School of Chemistry and Chemical Engineering,Shanghai JiaoTong University,Shanghai 200240) | 2011 | 化工进展2011，30，S2： | 0 |
