| 1 | Disentangling the effects of topography and space on the distributions of dominant species in a subtropical forest显示文摘Topography and space are two important factors determining plant species assemblages in forest communities.Quantification of the contribution of these two factors in determining species distribution helps us to evaluate their relative importance in determining species assemblages.This study aims to disentangle the effect of topography and space on the distributions of 14 dominant species in a subtropical mixed forest.Spearman correlation analysis and the torustranslation test were used to test the species–habitat associations.Variation partitioning was used to quantify the relative contributions of topography and space at three sampling scales and three life stages.Correlation analyses and torus-translation tests showed species abundance was mostly correlated with topographic wetness index,vertical distance from the channel network and convexity.Variation partitioning showed that pure topography,pure space and spatially structured topography explained about 2.1 %,41.2 % and 13.8 %of the variation in species distributions,respectively.For nine species,total topography fractions peaked in 20 m quadrats.For ten species,the pure space fractions peaked in 50 m quadrats.For many species,the total topography fraction andthe pure space fraction were larger for the most abundant life stages,which reflected the importance of sampling effect.However,some cases did not follow this trend suggesting that the effects of ecological processes such as habitat filtering,density dependence or dispersal limitation may exceed the sampling effects.In conclusion,we found that spatially structured topography and pure space primarily shaped the distribution of dominant tree species.Furthermore,their effects were both scale- and life stage-dependent. | Qinggang Wang Yaozhan Xu Zhijun Lu Dachuan Bao Yili Guo Junmeng Lu Kuihan Zhang Haibo Liu Hongjie Meng Xiujuan Qiao Handong Huang Mingxi Jiang | 2014 | Chinese Science Bulletin2014，59，35： | 16 |
| 2 | Synergistic effects between Suilllus luteus and Trichoderma virens on growth of Korean spruce seedlings and drought resistance of Scotch pine seedlings显示文摘Korean spruce(Picea koraiensis Sieb. El Zucc.)is one of the main afforestation species in northern China.Seedling quality is a critical factor at planting time. To test whether the synergistic growth enhancement of Scotch pine(P. sylvestris var. mongolica) seedlings brought by the plant beneficial fungus Trichoderma virens(J.H. Mill., Giddens and A.A. Foster) Arx and ectomycorrhizal fungus(Suillus luteus(L.) Roussel.) can also benefit Korean spruce seedlings, we examined the effects of S. luteus and T. virens on the growth of P. koraiensis seedlings and drought resistance of P. sylvestris var. mongolica in peat soils. The two fungi were added to sterilized peat soil in pots, and the plants were grown for 4 months. Seedling growth and physiological variables, including mycorrhizal colonization rate of roots,biomass, and chlorophyll content, were examined. The colonization rate of the mycorrhizal fungus on P. koraiensis exceeded 65 %, and the synergism between S. luteus and T.virens enhanced most of the variables for P. koraiensis seedlings after inoculation with S. luteus then 30 days later with T. virens as in our published results for seedlings of P.sylvestris var. mongolica. When seedlings of P. sylvestris var. mongolica were inoculated with this sequence, they became more drought tolerant. T. virens also induced S.luteus to produce-1,3-glucanase and chitinase. This inoculation sequence at planting can thus improve the quality of P. sylvestris var. mongolica and P. koraiensis seedlings and substantiates our previous results. | Dachuan Yin Xun Deng Ruiqing Song | 2016 | Journal of Forestry Research2016，27，1： | 11 |

| 6 | Ectomycorrhizal fungus enhances drought tolerance of Pinus sylvestris var.mongolica seedlings and improves soil condition显示文摘Mongolian pine is an important afforestation species widely used for ecological management in northeast China. The environment in this region is very unstable and the flora are regularly subjected to drought stress.This paper reports on the influence of inoculation with the Suillus luteus on seedlings under different water conditions.Both inoculated and non-inoculated ectomycorrhizal fungi(ECMF)-S. luteus seedlings were maintained under wellwatered or water-stress conditions for 3 months. The S.luteus colonization rate under water stress was higher than that in well-watered conditions. Under water stress, inoculated seedlings had greater growth than non-inoculated seedlings. In addition, under water stress, S. luteus-inoculated seedlings had greater superoxide dismutase and peroxidase activity, higher soluble protein content, lower proline content, and lower malondialdehyde content than non-inoculated seedlings. S. luteus colonization increased the rhizosphere soil-enzyme activity and the rhizosphere soil nutrition content under both well-watered and water-stress conditions. Given the positive impact on seedling growth and physiology, S. luteus shows potential for use in the arid and semi-arid regions of northeast China for afforestation. | Dachuan Yin Ruiqing Song Jinyu Qi Xun Deng | 2018 | Journal of Forestry Research2018，29，6： | 7 |
| 7 | Geology,Geochemistry and Zircon U-Pb Geochronology of Porphyries in the Dabate Mo-Cu Deposit,Western Tianshan,China:Petrogenesis and Tectonic Implications显示文摘The Dabate Mo-Cu deposit is a medium-sized porphyry-type deposit in the Sailimu Lake region, western Tianshan, China. We present the geology, geochemistry and zircon U-Pb geochronology of granite porphyries from the Dabate district with the intent to constrain their tectonic setting and petrogenesis. Porphyries in the Dabate district include granite porphyry I(gray white color with large phenocrysts), granite porphyry II(pink color with small phenocrysts) and quartz porphyry. Granite porphyry II is the Cu and Mo ore-bearing granitoid in the Dabate deposit. LA-ICPMS zircon U-Pb analyses indicate that granite porphyry II was emplaced at 284.2±1.8 Ma. Granite porphyry I and II have similar geochemical features and are both highly fractionated granites:(1) They have high SiO_2 content(70.93–80.18 wt% and 72.14–72.64 wt%, respectively), total alkali(7.58–8.95 wt% and 9.35–9.68 wt%, respectively), mafic index(0.95–0.98 and 0.93–0.94, respectively) and felsic index(0.79–0.94 and 0.89–0.91, respectively);(2) They are characterized by pronounced negative Eu anomaly, 'seagullstyle' chondrite-normalized REE patterns and 'tetrad effect' of REE;(3) They are rich in Rb, K, Th, Ta, Zr, Hf, Y and REE, but depleted in Sr, P, Ti and Nb. The magma of granite porphyries in Dabate can be interpreted to have been generated by partial melting of the upper crust due to mantle-derived magma underplating in a post-collisional extensional setting. | DUAN Shigang ZHANG Zuoheng WANG Dachuan LI Fengming | 2017 | Acta Geologica Sinica(English Edition)2017，91，2： | 7 |
| 8 | T cells promote the regeneration of neural precursor cells in the hippocampus of Alzheimer's disease mice显示文摘Alzheimer's disease is closely associated with disorders of neurogenesis in the brain, and growing evidence supports the involvement of immunological mechanisms in the development of the disease. However, at present, the role of T cells in neuronal regeneration in the brain is unknown. We injected amyloid-beta 1–42 peptide into the hippocampus of six BALB/c wild-type mice and six BALB/c-nude mice with T-cell immunodeficiency to establish an animal model of Alzheimer's disease. A further six mice of each genotype were injected with same volume of normal saline. Immunohistochemistry revealed that the number of regenerated neural progenitor cells in the hippocampus of BALB/c wild-type mice was significantly higher than that in BALB/c-nude mice. Quantitative fluorescence PCR assay showed that the expression levels of peripheral T cell-associated cytokines(interleukin-2, interferon-γ) and hippocampal microglia-related cytokines(interleukin-1β, tumor necrosis factor-α) correlated with the number of regenerated neural progenitor cells in the hippocampus. These results indicate that T cells promote hippocampal neurogenesis in Alzheimer's disease and T-cell immunodeficiency restricts neuronal regeneration in the hippocampus. The mechanism underlying the promotion of neuronal regeneration by T cells is mediated by an increased expression of peripheral T cells and central microglial cytokines in Alzheimer's disease mice. Our findings provide an experimental basis for understanding the role of T cells in Alzheimer's disease. | Jing Liu Yuxin Ma Sumin Tian Li Zhang Mengmeng Zhao Yaqiong Zhang Dachuan Xu | 2014 | Neural Regeneration Research2014，9，16： | 7 |
| 9 | Co-infections of SARS-CoV-2 with multiple common respiratory pathogens in infected patients显示文摘Dear Editor,In late December 2019,an outbreak of severe pneumonia caused by an unknown etiological agent was initially reported in Wuhan,China,and then quickly spread throughout China and even abroad(Zhu et al.,2020).Swift control measures and etiological investigations were conducted by the Chinese government,physicians and researchers,and by using high throughput sequencing and virological testing,the mysterious pneumonia pathogen was shown to be a novel coronavirus(SARS-CoV-2)capable of person-to-person transmission(Zhu et al.,2020).Coronaviruses are a group of non-segmented,enveloped and positive-sense RNA viruses that belong to the subfamily of Coronavirinae in the family of Coronavirdiae and order of Nidovirales. | Dachuan Lin Lei Liu Mingxia Zhang Yunlong Hu Qianting Yang Jiubiao Guo Yongchao Guo Youchao Dai Yuzhong Xu Yi Cai Xinchun Chen Zheng Zhang Kaisong Huang | 2020 | Science China(Life Sciences)2020，63，4： | 6 |
| 10 | Rotary-scaling fine-tuning (RSFT) method for optimizing railway wheel profiles and its application to a locomotive显示文摘The existing multi-objective wheel profile optimization methods mainly consist of three sub-modules:(1)wheel profile generation,(2)multi-body dynamics simulation,and(3)an optimization algorithm.For the first module,a comparably conservative rotary-scaling finetuning(RSFT)method,which introduces two design variables and an empirical formula,is proposed to fine-tune the traditional wheel profiles for improving their engineering applicability.For the second module,for the TRAXX locomotives serving on the Blankenburg–Rubeland line,an optimization function representing the relationship between the wheel profile and the wheel–rail wear number is established based on Kriging surrogate model(KSM).For the third module,a method combining the regression capability of KSM with the iterative computing power of particle swarm optimization(PSO)is proposed to quickly and reliably implement the task of optimizing wheel profiles.Finally,with the RSFT–KSM–PSO method,we propose two wear-resistant wheel profiles for the TRAXX locomotives serving on the Blankenburg–Rubeland line,namely S1002-S and S1002-M.The S1002-S profile minimizes the total wear number by 30%,while the S1002-M profile makes the wear distribution more uniform through a proper sacrifice of the tread wear number,and the total wear number is reduced by 21%.The quasi-static and hunting stability tests further demonstrate that the profile designed by the RSFT–KSM–PSO method is promising for practical engineering applications. | Yunguang Ye Yayun Qi Dachuan Shi Yu Sun Yichang Zhou Markus Hecht | 2020 | Railway Engineering Science2020，28，2： | 6 |

| 12 | Impurities evaporation from metallurgical-grade silicon in electron beam melting process显示文摘The purification of metallurgical-grade silicon (MG-Si) has been investigated during electron beam melting (EBM) process. The results show that the phosphorus, calcium and aluminum contents decrease significantly after melting, and magnesium is partially removed. However, no significant change in content for boron and iron has been found. Langmuir's equation and Henry law were used to derive the removal effi-ciency for each impurity element. The free surface temperature was estimated by the Hertz-Knudsen-Langmuir equation and silicon's vapor pressure equation. Good agreement was found between measured and calculated impurities' removal efficiency for phosphorus, calcium and aluminum, magnesium, boron and iron. The deviation between the two results was also analyzed in depth. | WANG Qiang DONG Wei TAN Yi JIANG Dachuan ZHANG Cong PENG Xu | 2011 | Rare Metals2011，30，3： | 5 |

| 14 | COPII mitigates ER stress by promoting formation of ER whorls显示文摘Cells mitigate ER stress through the unfolded protein response(UPR).Here,we report formation of ER whorls as an effector mechanism of the ER stress response.We found that strong ER stress induces formation of ER whorls,which contain ER-resident proteins such as the Sec61 complex and PKR-like ER kinase(PERK).ER whorl formation is dependent on PERK kinase activity and is mediated by COPII machinery,which facilitates ER membrane budding to form tubular-vesicular ER whorl precursors.ER whorl precursors then go through Sec22b-mediated fusion to form ER whorls.We further show that ER whorls contribute to ER stressinduced translational inhibition by possibly modulating PERK activity and by sequestering translocons in a ribosome-free environment.We propose that formation of ER whorls reflects a new type of ER stress response that controls inhibition of protein translation. | Fang Xu Wanqing Du Qin Zou Yuting Wang Xin Zhang Xudong Xing Ying Li Dachuan Zhang Huimin Wang Wenhao Zhang Xinyao Hu Xin Liu Xiaoling Liu Shaojin Zhang Jinqiang Yu Jianhuo Fang Fajin Li Ying Zhou Tieqiang Yue Na Mi Haiteng Deng Peng Zou Xiaowei Chen Xuerui Yang Li Yu | 2021 | Cell Research2021，31，2： | 4 |

| 16 | N-acetyltransferase 10 promotes colon cancer progression by inhibiting ferroptosis through N4-acetylation and stabilization of ferroptosis suppressor protein 1 (FSP1) mRNA显示文摘Background:N-acetyltransferase 10(NAT10)is the only enzyme known tomediate the N4-acetylcytidine(ac4C)modification of mRNA and is crucial formRNA stability and translation efficiency.However,its role in cancer development and prognosis has not yet been explored.This study aimed to examine the possible role of NAT10 in colon cancer.Methods:The expression levels ofNAT10were evaluated by immunohistochemical analyses with a colon cancer tissue microarray,and its prognostic value in patients was further analyzed.Quantitative real-time polymerase chain reaction(qRT-PCR)and Western blotting were performed to analyze NAT10 expression in harvested colon cancer tissues and cell lines.Stable NAT10-knockdown and NAT10-overexpressing colon cancer cell lines were constructed using lentivirus.The biological functions of NAT10 in colon cancer cell lines were analyzed in vitro by Cell Counting Kit-8(CCK-8),wound healing,Transwell,cell cycle,and ferroptosis assays.Xenograft models were used to analyze the effect of NAT10 on the tumorigenesis and metastasis of colon cancer cells in vivo.Dot blotting,acetylated RNA immunoprecipitation-qPCR,and RNA stability analyses were performed to explore the mechanism by which NAT10 functions in colon cancer progression.Results:NAT10 was upregulated in colon cancer tissues and various colon cancer cell lines.This increased NAT10 expression was associated with shorter patient survival.Knockdown of NAT10 in two colon cancer cell lines(HT-29 and LoVo)impaired the proliferation,migration,invasion,tumor formation and metastasis of these cells,whereas overexpression of NAT10 promoted these abilities.Further analysis revealed that NAT10 exerted a strong effect on the mRNA stability and expression of ferroptosis suppressor protein 1(FSP1)in HT-29 and LoVo cells.In these cells,FSP1 mRNA was found to be modified by ac4C acetylation,and this epigenetic modification was associated with the inhibition of ferroptosis.Conclusions:Our study revealed that NAT10 plays a critical role in colon cancer development by affecting FSP1 mRNA stability and ferroptosis,suggesting that NAT10 could be a novel prognostic and therapeutic target in colon cancer. | Xiao Zheng Qi Wang You Zhou Dachuan Zhang Yiting Geng Wenwei Hu Changping Wu Yufang Shi Jingting Jiang | 2022 | Cancer Communications2022，42，12： | 3 |
| 17 | TGF-β1-supplemented decellularized annulus fibrosus matrix hydrogels promote annulus fibrosus repair显示文摘Annulus fibrosus(AF)repair remains a challenge because of its limited self-healing ability.Endogenous repair strategies combining scaffolds and growth factors show great promise in AF repair.Although the unique and beneficial characteristics of decellularized extracellular matrix(ECM)in tissue repair have been demonstrated,the poor mechanical property of ECM hydrogels largely hinders their applications in tissue regeneration.In the present study,we combined polyethylene glycol diacrylate(PEGDA)and decellularized annulus fibrosus matrix(DAFM)to develop an injectable,photocurable hydrogel for AF repair.We found that the addition of PEGDA markedly improved the mechanical strength of DAFM hydrogels while maintaining their porous structure.Transforming growth factor-β1(TGF-β1)was further incorporated into PEGDA/DAFM hydrogels,and it could be continuously released from the hydrogel.The in vitro experiments showed that TGF-β1 facilitated the migration of AF cells.Furthermore,PEGDA/DAFM/TGF-β1 hydrogels supported the adhesion,proliferation,and increased ECM production of AF cells.In vivo repair performance of the hydrogels was assessed using a rat AF defect model.The results showed that the implantation of PEGDA/DAFM/TGF-β1 hydrogels effectively sealed the AF defect,prevented nucleus pulposus atrophy,retained disc height,and partially restored the biomechanical properties of disc.In addition,the implanted hydrogel was infiltrated by cells resembling AF cells and well integrated with adjacent AF tissue.In summary,findings from this study indicate that TGF-β1-supplemented DAFM hydrogels hold promise for AF repair. | Qiang Wei Dachuan Liu Genglei Chu Qifan Yu Zhao Liu Jiaying Li Qingchen Meng Weishan Wang Fengxuan Han Bin Li | 2023 | Bioactive Materials2023，，1： | 3 |
| 18 | Corrections of Original CFPREV Control in LCC-HVDC Links and Analysis of Its Inherent Plateau Effect显示文摘The most effective approach to suppressing the first commutation failure(CF)of the LCC-HVDC link at fault inception is to advance firings of the inverter,and the commutation failure prevention(CFPREV)control is the most commonly used method in practical engineering.However,it is discovered in this study that there exist a few serious defects in its original scheme,and thus targeted vital corrections were made.Furthermore,an interesting phenomenon termed the plateau effect,which states that an excessive advancement of firings will contrarily and inevitably lead to more commutation failures,is also revealed and analyzed.It turns out that the inherent commutation dents of the Graetz bridge should be primarily responsible,which bridges the knowledge gap and further enhances the cognition of the limitation of CFPREV control,and it may also be conducive to the design of related control parameters.Simulation results then validate the necessity of these presented corrections and confirm the existence of the plateau effect. | Dachuan Tian Xiaofu Xiong | 2022 | CSEE Journal of Power and Energy Systems2022，8，1： | 2 |

| 20 | Evaluation of the ventilation system in an LNG cargo tank construction platform (CTCP) by the AHP-entropy weight method显示文摘Owing to the vulnerability of Invar to moisture in the membranes of LNG tanker cargo tank construction platforms(CTCPs),an energy-efficient ventilation system is needed to maintain a suitable thermal-moisture environment and a healthy workplace.However,the optimal distribution of supply and return devices that would guarantee worker satisfaction,air quality,and energy efficiency is unclear.Therefore,we conducted numerical simulations to determine the worker satisfaction indices(temperature,relative humidity,and carbon monoxide concentration satisfactions),air quality index(contaminant-removal efficiency),and energy efficiency index(heat-removal efficiency)with supply vane angles ranging from-75°to 0°and two return vent positions(the bottom return vent and the top return vent).The analytic hierarchy process(AHP)entropy weight method was employed to determine the optimal supply vane angle and return vent position for three design targets by considering these indices simultaneously.The results indicated that,with a supply angle of-45°and a bottom return vent,worker satisfaction and air quality were prioritized.Furthermore,a high energy performance of the ventilation system was achieved with a-15°supply angle and a bottom return vent.Moreover,a comprehensive graph of supply vane angles at both return heights,which could provide a reference for optimizing the ventilation system in LNG-CTCPs,is described. | Dachuan Shi Yuejiao Guo Xinxin Gu Guozeng Feng Yang Xu Shaozhe Sun | 2022 | Building Simulation2022，15，7： | 2 |
