| 3 | Effects of Water-table Depth and Soil Moisture on Plant Biomass, Diversity, and Distribution at a Seasonally Flooded Wetland of Poyang Lake, China显示文摘Hydrological regime has been widely recognized as one of the major forces determining vegetation distribution in seasonally flooded wetland. Poyang Lake, the largest freshwater lake in China, has been encountering dramatic changes in hydrological conditions in last decade, which greatly influenced the wetland vegetations. To explore the relationships between hydrology and vegetation distribution, water-table depth, soil moisture, species composition, diversity and biomass were measured at a seasonally flooded wetland section at Wucheng National Nature Reserve. Three plant communities, Artemisia capillaris, Phragmites australis and Carex cinerascens communities, were examined which are zonally distributed from upland to lakeshore with decreasing elevation. Canonical correspondence analysis(CCA), spearmen correlation and logistic regression were adopted to analyze the relationships between vegetation characteristics and hydrological variables of water-table depth and soil moisture. Results show that significant hydrological gradient exist along the wetland transect. Water-table demonstrates a seasonal variation and is consistently deepest in A. capillaris community(ranging from –0.5 m above ground to +10.3 m below ground), intermediate in P. australis community(–2.6 m to +7.8 m) and shallowest in C. cinerascens community(–4.5 m to +6.1 m). Soil moisture is lowest and most variable in A. capillaris community, highest and least variable in P. australis community, and intermediate and moderate variable in C. cinerascens community. The CCA ordination indicated that variables of water-table depth and soil moisture are strongly related to community distribution, which explained 81.7% of the vegetation variations. Species diversity indices are significantly positively correlated with soil moisture and negatively correlated with moisture variability, while above- and belowground biomass are positively correlated with moisture. Above- and belowground biomass present Gaussian models along the gradient of average water-table depth in growing season, while species diversity indices show bimodal patterns. The optimal average water-table depths for above- and belowground biomass are 0.8 m and 0.5 m, respectively, and are 2.2 m and 2.4 m for species richness and Shannon-Wiener indices, respectively. Outcomes of this work improved the understandings of the relationship between hydrology and vegetation. | XU Xiuli ZHANG Qi TAN Zhiqiang LI Yunliang WANG Xiaolong | 2015 | Chinese Geographical Science2015，25，6： | 24 |

| 5 | Numerical simulation of powder transport behavior in laser cladding with coaxial powder feeding显示文摘Laser cladding with coaxial powder feeding is one of the new processes applied to produce well bonding coating on the component to improve performance of its surface. In the process, the clad material is transported by the carrying gas through the coaxial nozzle, generating gas-powder flow. The powder feeding process in the coaxial laser cladding has important influence on the clad qualities. A 3D numerical model was developed to study the powder stream structure of a coaxial feeding nozzle. The predicted powder stream structure was well agreed with the experimental one. The validated model was used to explore the collision behavior of particles in the coaxial nozzle, as well as powder concentration distribution. It was found that the particle diameter and restitution coefficient greatly affect the velocity vector at outlet of nozzle due to the collisions, as well as the powder stream convergence characteristics below the nozzle. The results indicated a practical approach to optimize the powder stream for the coaxial laser cladding. | LIU Hao HE XiuLi YU Gang WANG Zhong Bin LI ShaoXia ZHENG CaiYun NING WeiJian | 2015 | Science China(Physics,Mechanics & Astronomy)2015，58，10： | 17 |

| 9 | Western medication plus Traditional Chinese Medicine preparations in patients with chronic heart failure:a prospective,single-blind,randomized,controlled,and multicenter clinical trial显示文摘OBJECTIVE: To assess the efficacy and safety in patients with chronic heart failure(CHF) of Western medication plus Traditional Chinese Medicine(TCM) preparations.METHODS: This prospective, single-blind, randomized, controlled, and multicenter clinical trial began on September 17, 2008, and was completed on June 25, 2011. A total of 340 inpatients, aged 40-79 years, with exacerbating CHF from 10 hospitals were enrolled and randomly allocated within 24 h of admission. The trial included three intervention periods. During hospitalization, the control group received western medication for CHF and the treatment group received Danhong injection with Shenfu injection or Shenmai injection. After discharge,all patients were treated with Qiliqiangxin capsules and Buyiqiangxin tablets or a placebo for 6 months. After the 6-month intervention, both groups received only continuous western medication. The primary endpoint was all-cause mortality.The efficacy assessments were as follows: B-type natriuretic peptide(BNP), Lee's HF score, the 6-minute walking test(6 MWT), left ventricular ejection fraction(LVEF), and the Minnesota Living with Heart Failure Questionnaire(MLHFQ). The safety assessments were as follows: blood and urine routine examination, hepatic and renal function, electrolytes in blood and adverse events.RESULTS: Compared with the control group, the treatment group showed a 30.99% reduction in all-cause mortality and an improved survival rate.The treatment group showed greater improvement in 6 MWT(P = 0.02) than the control group on discharge, after 12-month follow-up, there was a time-group interaction for MLHFQ(P = 0.03). Incidence rate of adverse events and other relevant safety indexes were not statistically significant between the two groups.CONCLUSION: Western medication plus TCM treatment can increase 6-minute walking distance(improve exercise tolerance) and quality of life with heart failure patients. | Wang Xianliang Hou Yazhu Mao Jingyuan Zhao Yingqiang Niu Tianfu Yuan Ruyu Wang Yonggang Cui Jin-rong Shi Le Jia Xiuli Fan Ruihong Lin Qian Zhang Yan Li Zhijun Shang Hongcai Wang Baohe Wang Hongwu Wang Henghe Cui Xiaolei Soh Shanbin Ruan Jishou Zhang Boli | 2017 | Journal of Traditional Chinese Medicine2017，37，6： | 15 |

| 11 | Major and trace element geochemistry of the mid-Bay of Bengal surface sediments: implications for provenance显示文摘The major and trace elements in 110 surface sediment samples collected from the middle of the Bay of Bengal(mid-Bay of Bengal) are analyzed to investigate provenance. Si levels are highest, followed by Al, and the distributions of these two elements are identical. The average CIA*(chemical index of alteration) value is 72.07,indicating that the degree of weathering of the sediments in the study area is intermediate between those of sediments of the Himalayan and Indian rivers. Factor analyses and discrimination function analyses imply that the two main provenances are the Himalayan and the Indian continent. The inverse model calculation of the Tinormalized element ratios of the Bay of Bengal sediments indicate an estimated average contribution of 83.5%and 16.5% from the Himalayan and peninsular Indian rivers to the study area, respectively. The Himalayan source contributes more sediment to the eastern part of the study area, whereas the western part receives more sediment from the Indian Peninsula than did the eastern part. The primary mechanisms for deposition of sediments in the study area are the transport of Himalayan matter by turbidity currents and river-diluted water and the transport of Indian matter to the study area by a surface circulation in the Bay of Bengal, particularly the East India Coastal Current. | LI Jingrui LIU Shengfa FENG Xiuli SUN Xingquan SHI Xuefa | 2017 | Acta Oceanologica Sinica2017，36，3： | 12 |
| 12 | Transplantation of placenta-derived mesenchymal stem cells reduces hypoxic-ischemic brain damage in rats by ameliorating the inflammatory response显示文摘Hypoxic-ischemic brain damage(HIBD)is a common cause of infant death.The purpose of our research was to explore the immunoregulatory mechanism of placenta-derived mesenchymal stem cells(PD-MSCs)in HIBD treatment.Seven-day-old rat pups were randomly divided into HIBD,PD-MSC,fibroblast,and control groups.Forty-eight hours after HIBD induction,cells at a density of 5×104 cells/10µl were injected into the cerebral tissue in the PD-MSC and fibroblast groups.The TNF-α,interleukin-17(IL-17),interferon-γ(IFN-γ),and IL-10 levels were detected through quantitative real-time polymerase chain reaction(RT-PCR)and enzyme-linked immunosorbent assay(ELISA).Regulatory T cell(Tregs)populations were detected through flow cytometry,and forkhead box P3(Foxp3)was measured through western blot analysis.Behavioral tests and gross and pathological examinations showed that PD-MSC treatment exerted significantly stronger neuroprotective effects than the other treatments.The expression levels of pro-inflammatory cytokines were substantially upregulated after HI injury.Compared with fibroblast treatment,PD-MSC treatment inhibited the production of pro-inflammatory cytokines and increased the production of IL-10 in the ischemic hemispheres and peripheral blood serum(all P<0.01).Flow cytometry results showed a notable increase in the number of Tregs within the spleen of the HIBD group.Moreover,the number of Tregs and the Foxp3 expression levels were higher in the PD-MSC treatment group than in the HIBD and fibroblast groups(all P<0.01).Our research suggests that the mechanism of PD-MSC treatment for HIBD partially involves inflammatory response suppression. | Hongfang Ding Hui Zhang Huifang Ding Dong Li Xinhao Yi Xiaoxu Ma Ruijuan Li Mei Huang Xiuli Ju | 2017 | Cellular & Molecular Immunology2017，14，8： | 10 |
| 13 | Multi-scale thermodynamic analysis method for 2D SiC/SiC composite turbine guide vanes显示文摘Ceramic Matrix Composite(CMC) turbine guide vanes possess multi-scale stress and strain with inhomogeneity at the microscopic scale.Given that the macroscopic distribution cannot reflect the microscopic stress fluctuation, the macroscopic method fails to meet the requirements of stress and strain analysis of CMC turbine guide vanes.Furthermore, the complete thermodynamic properties of 2 D woven SiC/SiC-CMC cannot be obtained through experimentation.Accordingly,a method to calculate the thermodynamic properties of CMC and analyze multi-scale stress and strain of the turbine guide vanes should be established.In this study, the multi-scale thermodynamic analysis is investigated.The thermodynamic properties of Chemical Vapor Infiltration(CVI) processed SiC/SiC-CMC are predicted by a Representative Volume Element(RVE) model with porosity, leading to the result that the relative error between the calculated in-plane tensile modulus and the experimental value is 4.2%.The macroscopic response of a guide vane under given conditions is predicted.The relative error between the predicted strain on the trailing edge and the experimental value is 9.7%.The calculation of the stress distribution of micro-scale RVE shows that the maximum value of microscopic stress, which is located in the interlayer matrix, is more than 1.5 times that of macroscopic stress in the same direction and the microscopic stress distribution of the interlayer matrix is related to the pore distribution of the composite. | Xin LIU Xiuli SHEN Longdong GONG Peng LI | 2018 | Chinese Journal of Aeronautics2018，31，1： | 9 |
| 14 | Programmed Death Ligand-1 on Microglia Regulates Th1 Differentiation via Nitric Oxide in Experimental Autoimmune Encephalomyelitis显示文摘Microglia are considered to be potential antigen-presenting cells and have the ability to present antigen under pathological conditions. Nevertheless, whether and how microglia are involved in immune regulation are largely unknown. Here, we investigated the suppressive activity of microglia during experimental autoimmune encephalomyelitis(EAE) induced by myelin oligodendrocyte glycoprotein, with the goal of understanding their role in regulating the T cell reaction. Using flow cytometric analysis, we found that microglia were characterized by increased cell number and up-regulated programmed death ligand-1(PD-L1) at the peak phase of EAE. Meanwhile,both the CD^(4+)T cells and microglia that infiltrated the central nervous system expressed higher levels of PD1, the receptor for PD-L1, accompanied by a decline of Th1 cells.In an ex vivo co-culture system, microglia from EAE mice inhibited the proliferation of antigen-specific CD^(4+)T cells and the differentiation of Th1 cells, and this was significantly inhibited by PD-L1 blockade. Further,microglia suppressed Th1 cells via nitric oxide(NO), the production of which was dependent on PD-L1. Thus, these data suggest a scenario in which microglia are involved in the regulation of EAE by suppressing Th1-cell differentiation via the PD-L1-NO pathway. | Jingxia Hu Hao He Zhengang Yang Guangming Zhu Li Kang Xiuli Jing Hai Lu Wengang Song Bo Bai Hua Tang | 2016 | Neuroscience Bulletin2016，32，1： | 9 |
| 15 | Local icariin application enhanced periodontal tissue regeneration and relieved local inflammation in a minipig model of periodontitis显示文摘Periodontitis is an inflammatory autoimmune disease. Treatment should alleviate inflammation, regulate the immune reaction and promote periodontal tissue regeneration. Icariin is the main active ingredient of Epimedii Folium, and it is a promising compound for the enhancement of mesenchymal stem cell function, promotion of bone formation, inhibition of bone resorption, alleviation of inflammation and regulation of immunity. The study investigated the effect of icariin on periodontal tissue regeneration in a minipig model of periodontitis. The minipig model of periodontitis was established. Icariin was injected locally. The periodontal clinical assessment index, a computed tomography(CT) scan, histopathology and enzyme-linked immune sorbent assay(ELISA)were used to evaluate the effects of icariin. Quantitative analysis results 12 weeks post-injection demonstrated that probing depth,gingival recession, attachment loss and alveolar bone regeneration values were(3.72 ± 1.18) mm vs.(6.56 ± 1.47) mm,(1.67 ± 0.59)mm vs.(2.38 ± 0.61) mm,(5.56 ± 1.29) mm vs.(8.61 ± 1.72) mm, and(25.65 ± 5.13) mm3 vs.(9.48 ± 1.78) mm3 in the icariin group and0.9% NaCl group, respectively. The clinical assessment, CT scan, and histopathology results demonstrated significant enhancement of periodontal tissue regeneration in the icariin group compared to the 0.9% NaCl group. The ELISA results suggested that the concentration of interleukin-1 beta(IL-1β) in the icariin group was downregulated compared to the 0.9% NaCl group, which indicates that local injection of icariin relieved local inflammation in a minipig model of periodontitis. Local injection of icariin promoted periodontal tissue regeneration and exerted anti-inflammatory and immunomodulatory function. These results support the application of icariin for the clinical treatment of periodontitis. | Xiuli Zhang Nannan Han Guoqing Li Haoqing Yang Yangyang Cao Zhipeng Fan Fengqiu Zhang | 2018 | International Journal of Oral Science2018，10，3： | 9 |

| 20 | Deformation mechanism and microstructures on polycrystalline aluminum induced by high-current pulsed electron beam显示文摘In this paper, we present an experimental investigation of deformation twinning in polycrystalline aluminum exposed to high-current pulsed electron beam (HCPEB) irradiation. The residual tensile stress with about 10 2 MPa was introduced in the irradiated surface layer. The feature characteristic irradiated with various numbers of pulses was investigated. The formation of a large number of twin bands on the surface irradiated with multiple pulses was determined. The experimental observations indicated that the deformation twinning was indeed triggered during HCPEB irradiation. It is suggested that high value of stress and strain rate induced by rapid heating and cooling due to HCPEB irradiation may cause the shifting of whole atomic planes simultaneously. Additionally, some slipping systems may be suppressed due to the geometric confinement by thinned size of surface layer, which can promote the initiation of deformation twinning. | CAI Jie JI Le YANG ShengZhi WANG XiaoTong LI Yan HOU XiuLi GUAN QingFeng | 2013 | Chinese Science Bulletin2013，58，20： | 7 |
