| 1 | 近年中国北方草地变绿受降水增加的驱动显示文摘中国北方的暖湿化是近期的热点话题,然而其对植被生长的影响仍不清楚。本研究基于长时间序列(1982–2018年)数据,研究了归一化植被指数(NDVI)的时间动态及其气候驱动因子之间的关系,以探索近年来气候的暖湿化是否会导致该区植被变绿。我们采用分段回归探测了NDVI的变化趋势是否存在转变点,用Pearson相关分析描述了植被指数与气候因子的关系。最后,采用逐步多元回归方法研究了气候因子对NDVI时间变化的贡献率。研究结果表明,NDVI时间变化趋势的转变点出现在2008年,GIMMS NDVI在1982–2008年略有增加,上升速率为0.00022 yr?1,在2008–2015年上升速率达到0.002 yr?1,MODIS NDVI在2008–2018年上升速率为0.0018 yr?1。降水是NDVI变化的主要驱动因子,气温和饱和水汽压差(VPD)对NDVI的变化影响较小。总体看来,NDVI时间序列变化趋势存在转变点,并且近期气候的暖湿化主导了中国北方草地植被变绿,这为今后更好地预测该地区气候变化下的植被覆盖变化提供了依据。 | Kai Di Zhongmin Hu Mei Wang Ruochen Cao Minqi Liang Genan Wu Ruru Chen Guangcun Hao Yaolong Zhao | 2021 | Journal of Plant Ecology2021，14，5： | 2 |
| 2 | Distributed implantation of a flexible microelectrode array for neural recording显示文摘Flexible multichannel electrode arrays(fMEAs)with multiple flaments can be flexibly implanted in various patterns.It is necessary to develop a method for implanting the fMEA in different locations and at various depths based on the recording demands.This study proposed a strategy for reducing the microelectrode volume with integrated packaging.An implantation system was developed specifically for semiautomatic distributed implantation.The feasibility and convenience of the fMEA and implantation platform were verified in rodents.The acute and chronic recording results provied the effectiveness of the packaging and implantation methods.These methods could provide a novel strategy for developing fMEAs with more flaments and recording sites to measure functional interactions across multiple brain regions. | Chunrong Wei Yang Wang Weihua Pei Xinyong Han Longnian Lin Zhiduo Liu Gege Ming Ruru Chen Pingping Wu Xiaowei Yang Li Zheng Yijun Wang | 2022 | Microsystems & Nanoengineering2022，8，3： | 1 |
| 3 | Immunosuppressive therapy selectively modulates B-cell responses in patients with rheumatic and musculoskeletal diseases receiving the inactivated COVID-19 vaccine显示文摘Background:Immunosuppressive medication reduces the immunogenicity of the coronavirus disease 2019(COVID-19)vaccines in patients with rheumatic and musculoskeletal diseases(RMDs).However,the underlying mechanism remains unclear.The primary aim of our study was to dissect the impact of immunosuppressive medication on cellular and humoral immune responses in RMD patients receiving the inactivated COVID-19 vaccine.Methods:A total of 28 RMD patients and five healthy controls(HCs)receiving two doses of the inactivated COVID-19 vaccine(Sinovac-CoronaVac)were prospectively enrolled.Blood samples were collected before the primary vaccination(Week 0)and one week after the second vaccination(Week 5).Neutralizing antibody(nAb)titers and autoantibody titers were measured by a pseudovirus-based neutralization assay and enzyme-linked immunosorbent assay,respectively.CD4^(+)T-cell and CD19^(+)B-cell subsets and serum cytokines were analyzed by flow cytometry.Results:The inactivated COVID-19 vaccine was immunogenic in RMD patients and HCs after the second vaccination,but the nAb titers were lower in RMD patients than those in HCs.Only patients with systemic lupus erythematosus(SLE)had notably increased nAb titers.Remarkably,IgG^(+)CD27^(+),IgG^(+)IgG1^(+),and IgG^(+)IgG1^(−)B cells were reduced,whereas IgG−IgG1^(+)B cells,and total IgA and IgG titers were markedly increased.However,Tfh cell and Tfr cell subsets and cytokines produced by Tfh cells were not increased.The flare rate was low in RMD patients with comparable autoantibody titers,unchanged CD4^(+)T cell subsets and serum proinflammatory cytokines(interleukin[IL]-6,IL-17,interferon-γ,and tumor necrosis factor-α)after the second vaccination.Conclusions:Immunosuppressive therapy decreased the immunogenicity of the vaccine and maintained a low flare rate by selectively modulating B cell but not CD4^(+)T cell responses in RMD patients receiving the inactivated COVID-19 vaccine.Optimization of the treatment regimen might ensure a durable and robust COVID-19 vaccination response. | Rui Li Ruru Guo Jia Li Bing Zheng Ronghao Xu Xiaoyue Jiang Yingying Chen Guo Tang Qianqian Li Yixuan Li Jiaqi Feng Xiaoxiang Chen Ying Wang Shuang Ye Fang Du Liangjing Lu Jun Deng | 2023 | Rheumatology & Autoimmunity2023，3，2： | 0 |
| 4 | Superhydrophilic Polydopamine‑Modified Carbon‑Fiber Membrane with Rapid Seawater‑Transferring Ability for Constructing Efficient Hanging‑Model Evaporator显示文摘Solar-driven seawater desalination has attracted much attention for alleviating global freshwater shortage,but the practical application is often limited by complicated fabrication processes,unsatisfactory seawater-transferring and severe salt accu-mulation on the photothermal membranes.To solve these problems,hydrophobic industrial-grade carbon fiber membrane(CFM)with good photoabsorption was surface-modified with polydopamine(PDA)to prepare superhydrophilic CFM@PDA for the construction of efficient hanging-model evaporators without salt accumulation.The coating of PDA on CFM is realized by simple self-polymerization of dopamine,and the as-prepared CFM@PDA exhibits high solar absorption effi-ciency of 96.7%,good photothermal effect and superhydrophilicity.Especially,when CFM@PDA is hanging between two water tanks(one contains seawater and the other is empty)in a flat hanging-model evaporator,it can transport seawater at a high rate(26.35 g/h)which is 3.6 times that(7.28 g/h)of commercial cotton fabric.Under simulated sunlight(1.0 kW m^(-2))irradiation,CFM@PDA shows a high evaporation rate of 1.79 kg m^(-2) h^(-1) with a solar evaporation efficiency of 92.6%.Even if NaCl solution with a high concentration(21.0 wt%)is used for the evaporation,the hanging CFM@PDA can retain a high evaporation rate(~1.80 kg m^(-2) h^(-1))without salt accumulation during the long-time test(8 h),which is significantly better than that of the tradition floating model.Therefore,this study not only demonstrates the simple preparation of super-hydrophilic CFM@PDA,but also promotes the further practical applications of hanging-model evaporators for continuous salt-free desalination. | Wenmei Chong Ruru Meng Zixiao Liu Qiyue Liu Jinjing Hu Bo Zhu Daniel KMacharia Zhigang Chen Lisha Zhang | 2023 | Advanced Fiber Materials2023，5，3： | 0 |
| 5 | Analysis on Interface Characteristics of FeNi_p/PP Nanocomposites显示文摘The FeNip/PP nanocomposites were successfully prepared by the two-step blending method and the permeable layer interface with thickness of 2 to 10 nm was formed on the surface of nanopowders. The interface is composed of the lattice and molecular chain, in which the polypropylene molecular chain enters the lattice defects and forms a cross-linked structure. The interface causes the FeNi nanopowders to be well compatible with the polypropylene matrix and uniformly dispersed in the matrix, and significantly improves the mechanical properties of composites. The tensile strength of 2 wt% FeNip/PP composites reached 38 MPa, 23% higher than that of pure PP resin. The shielding performance of 20 wt% FeNip/PP composites reached 9.8 dB in the frequency range of 1-100 MHz. | 钟麒 朱正吼 BAI Ruru CHEN Jie | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，6： | 0 |
