| 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 | Plasma biomarker screening for liver fibrosis with the N-terminal isotope tagging strategy显示文摘A non-invasive diagnostic approach is crucial for the evaluation of severity of liver disease,treatment decisions,and assessing drug efficacy.This study evaluated plasma proteomic profiling via an N-terminal isotope tagging strategy coupled with liquid chromatography/Fourier transform ion cyclotron resonance mass spectrometry measurement to detect liver fibrosis staging.Pooled plasma from different liver fibrosis stages,which were assessed in advance by the current gold-standard of liver biopsy,was quantitatively analyzed.A total of 72 plasma proteins were found to be dysregulated during the fibrogenesis process,and this finding constituted a valuable candidate plasma biomarker bank for follow-up analysis.Validation results of fibronectin by Western blotting reconfirmed the mass-based data.Ingenuity Pathways Analysis showed four types of metabolic networks for the functional effect of liver fibrosis disease in chronic hepatitis B patients.Consequently,quantitative proteomics via the N-terminal acetyl isotope labeling technique provides an effective and useful tool for screening plasma candidate biomarkers for liver fibrosis.We quantitatively monitored the fibrogenesis process in CHB patients.We discovered many new valuable candidate biomarkers for the diagnosis of liver fibrosis and also partly identified the mechanism involved in liver fibrosis disease.These results provide a clearer understanding of liver fibrosis pathophysiology and will also hopefully lead to improvement of clinical diagnosis and treatment. | LI ShuLong LIU Xin WEI Lai WANG HuiFen ZHANG JiYang WEI HanDong QIAN XiaoHong JIANG Ying HE FuChu | 2011 | Science China(Life Sciences)2011，54，5： | 6 |

| 6 | Effect of photoionisation on initial discharge in air under nanosecond pulse voltage显示文摘Effects of photoionisation on the development and electron runaway of the initial discharge in atmospheric air under nanosecond pulse voltage were studied via twodimensional particle-in-cell/Monte Carlo collision simulations.It was found that photoionisation has little effect at the beginning of the initial discharge.However,as the discharge channel gradually develops towards the anode,photoionisation shows greater impacts on the morphology of discharge but has little influence on the velocity of discharge development.Photoionisation does not appear to have a decisive effect on the growth trend of the highest energy of runaway electrons,but it does affect the change rate of the highest energy and overall distribution of electron energy,resulting in a higher proportion of energetic electrons.The difference in the distributions of the electron energy between the two cases,with and without considering photoionisation,can be attributed to the impact of photoionisation on the discharge morphology,which in turn distorted the electric field.The spatial density distributions of the electrons produced by photoionisation further explained the differences.The authors’results explicitly demonstrate the influence of photoionisation on the development and the electron runaway of the initial discharge under nanosecond pulse voltage,which provides more comprehensive knowledge for the atmospheric air gap nanosecond pulse discharge physics. | Yutai Li Yangyang Fu Zhigang Liu Handong Li Peng Wang Haiyun Luo Xiaobing Zou Xinxin Wang | 2023 | High Voltage2023，8，2： | 2 |

| 15 | Al homogeneous deposition induced by N-containing functional groups for enhanced cycling stability of Al-ion battery negative electrode显示文摘Rechargeable Al-ion batteries(AIBs)are considered as one of the most fascinating energy storage systems due to abundant Al resource and low cost.However,the cycling stability is subjected to critical problems for using Al foil as negative electrode,including Al dendrites,corrosion and pulverization.For addressing these problems,here a lightweight self-supporting N-doped carbon rod array(NCRA)is demonstrated for a long-life negative electrode in AIBs.Experimental analysis and first-principle calculations reveal the storage mechanism involving the induced deposition of N-containing function groups to Al as well as the ideal skeleton of the NCRA matrix for Al plating/stripping,which is favorable for regulating Al nucleation and suppressing dendrites growth.Compared with the Al foil,the NCRA exhibits lower areal mass density(∼72%of Al foil),smaller thickness(40%of Al foil),but much longer cycle life(>4 times of Al foil).Benefiting from the remarkable stability of the array structure,symmetric cells show excellent cycling stability with small voltage hysteresis(∼80 mV)and meanwhile there are no corrosion and pulverization problems even after cycled for 120 hours.Besides,full cells also manifest long lifespan(1,500 cycles)and increased Coulombic efficiency(100±1%). | Handong Jiao Shuqiang Jiao Wei-Li Song Xiang Xiao Dongmei She Na Li Haosen Chen Jiguo Tu Mingyong Wang Daining Fang | 2021 | Nano Research2021，14，3： | 1 |
| 16 | Mechanisms of antinociceptive effects of ouabain in combination with neostigmine in the rat显示文摘BACKGROUND: It has been previously shown that intrathecal administration of either ouabain or neostigmine can produce antinociceptive effects. Moreover, ouabain and neostigmine are differently associated with acetylcholine. OBJECTIVE: It has been hypothesized that intrathecal administration of ouabain, in combination with neostigmine, can produce antinociceptive synergistic effects. Atropine, as a competitive antagonist, was pre-injected to verify the mechanisms of action. DESIGN, TIME AND SETTING: This study was a randomized, controlled, animal experiment, performed at the State Key Laboratory of Oncology in Southern China between May 2006 and February 2007. MATERIALS: A total of 102 healthy, adult, Sprague Dawley rats were included. Ouabain and neostigmine (Sigma, USA), as well as atropine (Tanabe Seiyaku, Japan), were also used. METHODS: Varied doses of ouabain, neostigmine, and a combination of the two were intrathecally injected into rats. Six rats were allotted for each dose group. Intrathecal pretreatment with atropine was tested 10 minutes prior to intrathecal administration of neostigmine or the combination of ouabain and neostigmine. MAIN OUTCOME MEASURES: Tail-flick tests were performed to measure tail-flick latency (seconds) prior to and after administration. The response in the tail-flick test was expressed as the percentage of maximum possible effect (% MPE), where % MPE = [tail-flick latency after administration (seconds) -mean baseline value for tail-flick latency]/[10 seconds - the mean baseline value for tail-flick latency (seconds)] × 100%. RESULTS: Rat spinal intrathecal administration of either ouabain or neostigmine alone produced antinociceptive effects in a dose-dependent manner. Intrathecally administration of neostigmine (0.05, 0.1, 0.3 μg ) in combination with ouabain (1 μg ) produced enhanced antinociceptive effects, with a % MPE of 29%, 78%, and 95%, respectively (P < 0.05). Intrathecally administration of 0.3 μg neostigmine (% MPE: 45%), in combination with 1 μg ouabain (% MPE: 27%) produced potent antinociceptive effects (% MPE: 95%). Intrathecally pre-injected atropine antagonized the antinociceptive effects of neostigmine (3 μg), or a combination of ouabain (1 μg) and neostigmine (0.3 μg) (P < 0.01). CONCLUSION: Rat spinal intrathecal administration of either ouabain or neostigmine alone produced dose-dependent antinociceptive effects. Ouabain enhanced the antinociceptive effects of neostigmine. Atropine antagonized the antinociceptive effects of neostigmine or the combination of ouabain and neostigmine. This occurs possibly due to the fact that atropine is a competitive antagonist of the muscarinic acetylcholine receptors. | Handong Ouyang Qiang Li Weian Zeng Weixiong He Peizong Wang | 2008 | Neural Regeneration Research2008，3，7： | 1 |

| 18 | Anomalous phenomena in DC–ULF geomagnetic daily variation registered three days before the 12 May 2008 Wenchuan M_S 8.0 earthquake显示文摘The hourly data of the vertical Z and the horizontal H components of 37 ground-based DC-ULF geomagnetic stations are examined during 20 April-12 May 2008. On 9 May 2008, three days before the Wenchuan MS 8.0 shock, anomalies-a double low-point and a decreased amplitude-are registered on the curves of the Z component at 25 stations in a large-scale area surrounding the Wenchuan epicentral area. The H component shows none of the double low-point phenomenon but does exhibit a reduced magnitude at the same time. The geomagnetic index Kp is also examined and indicates that the anomalies appear at a solar quiet period. The appearing time shift(Tzs) between the first low-point on May 9 and the minimum point occurring time of May 1-5, 2008 is also checked.The results show that Tzs is on the order of 1-2 hours earlier or later than usual and there is a 2-6 hours’ gap between these two lowpoints. However, there is still a transition area which includes the epicenter where Tzs=0. Variation amplitude examined on vertical Z increases as the distance from the epicenter decreases. An Earth-air-ionosphere model has been employed to investigate a possible mechanism of this phenomenon and positive results have been unexpectedly attained. All these above-related results tend to prove that the variations of the Z and H on May 9, 2008 during the solar quiet period are probably associated with the forthcoming Wenchuan MS 8.0 earthquake. | Mei Li Li Yao YaLi Wang Michel Parrot Masashi Hayakawa Jun Lu HanDong Tan Tao Xie | 2019 | Earth and Planetary Physics2019，3，4： | 1 |

| 20 | Alternations in the gut microbiota and metabolome with newly diagnosed unstable angina显示文摘Gut microbiota plays an important role in coronary heart disease, but its compositional and functional changes in unstable angina(UA) remain unexplored. We performed metagenomic sequencing of 133 newly diagnosed UA patients and 133 sex-and age-matched controls, and profiled the fecal and plasma metabolomes in 30 case-control pairs. The alpha diversity of gut microbiota was increased in UA patients:the adjusted odds ratios(ORs) per standard deviation increase in Shannon and Simpson indices were 1.30(95% confidence interval, 1.01-1.70) and 1.36(1.05-1.81), respectively. Two common species(depleted Klebsiella pneumoniae and enriched Streptococcus parasanguinis;P ≤ 0.002) and three rare species(depleted Weissella confusa, enriched Granulicatella adiacens and Erysipelotrichaceae bacterium 6_1_45;P ≤ 0.005) were associated with UA. The UA-associated gut microbiota was depleted in the pathway of Lphenylalanine degradation(P = 0.001), primarily contributed by Klebsiella pneumoniae. Consistently, we found increased circulating phenylalanine in UA patients(OR = 2.76 [1.17-8.16]). Moreover, Streptococcus parasanguinis was negatively correlated with fecal citrulline(Spearman's r_(s)=-0.470, P = 0.009), a metabolite depleted in UA patients(OR = 0.26 [0.08-0.63]). These findings are informative to help understand the metabolic connection between gut microbiota and UA. | Xuezhen Liu Miaoyan Shen Han Yan Pinpin Long Haijing Jiang Yizhi Zhang Lue Zhou Kuai Yu Gaokun Qiu Handong Yang Xiulou Li Xinwen Min Meian He Xiaomin Zhang Hyungwon Choi Chaolong Wang Tangchun Wu | 2022 | Journal of Genetics and Genomics2022，49，3： | 1 |
