| 5 | Application of computational fluid dynamic to model the hydraulic performance of subsurface flow wetlands显示文摘A subsurface flow wetland(SSFW)was simulated using a commercial computational fluid dynamic(CFD)code.The constructed media was simulated using porous media and the liquid resident time distribution(RTD)in the SSFW was obtained using the particle trajectory model.The effect of wetland configuration and operating conditions on the hydraulic performance of the SSFW were investigated.The results indicated that the hydraulic performance of the SSFW was predominantly affected by the wetland configuration.The hydraulic effciency of the SSFW with an inlet at the middle edge of the upper media was 0.584 and the best among the SSFWs with an inlet at the top,the middle,and the bottom edge of the upper media.The constructed media affected the hydraulic performance by the ratio(K)of the upper and lower media resistance.The selection of appropriate media resistance in the protection layer can improve the hydraulic effciency.When the viscous resistance coeffcient of the media in the protection layer changed from 2.315×105 to 1.200×108,the hydraulic effciency of the SSFW increased from 0.301 to 0.751.However,the effect of operating conditions on the hydraulic effciency of the SSFW was slight. | Liwei FAN Hai Reti Wenxing WANG Zexiang LU Zhiming YANG | 2008 | Journal of Environmental Sciences2008，20，12： | 17 |
| 6 | Ultrasound enhanced heterogeneous activation of peroxydisulfate by bimetallic Fe-Co/GAC catalyst for the degradation of Acid Orange 7 in water显示文摘Bimetallic Fe-Co/GAC(granular activated carbon) was prepared and used as heterogeneous catalyst in the ultrasound enhanced heterogeneous activation of peroxydisulfate(PS, S2O2-8) process. The effect of initial pH, PS concentration, catalyst addition and stirring rate on the decolorization of Acid Orange 7(AO7) was investigated. The results showed that the decolorization efficiency increased with an increase in PS concentration from 0.3 to 0.5 g/L and an increase in catalyst amount from 0.5 to 0.8g/L. But further increase in PS concentration and catalyst addition would result in an unpronounced increase in decolorization efficiency. In the range of 300 to 900 r/min, stirring rate had little effect on AO7 decolorization. The catalyst stability was evaluated by measuring decolorization efficiency for four successive cycles. | Chun Cai Liguo Wang Hong Gao Liwei Hou Hui Zhang | 2014 | Journal of Environmental Sciences2014，26，6： | 16 |

| 9 | Human carboxylesterases:a comprehensive review显示文摘Mammalian carboxylesterases(CEs) are key enzymes from the serine hydrolase superfamily.In the human body, two predominant carboxylesterases(CES1 and CES2) have been identified and extensively studied over the past decade. These two enzymes play crucial roles in the metabolism of a wide variety of endogenous esters, ester-containing drugs and environmental toxicants. The key roles of CES in both human health and xenobiotic metabolism arouse great interest in the discovery of potent CES modulators to regulate endobiotic metabolism or to improve the efficacy of ester drugs. This review covers the structural and catalytic features of CES, tissue distributions, biological functions, genetic polymorphisms, substrate specificities and inhibitor properties of CES1 and CES2, as well as the significance and recent progress on the discovery of CES modulators. The information presented here will help pharmacologists explore the relevance of CES to human diseases or to assign the contribution of certain CES in xenobiotic metabolism. It will also facilitate medicinal chemistry efforts to design prodrugs activated by a given CES isoform, or to develop potent and selective modulators of CES for potential biomedical applications. | Dandan Wang Liwei Zou Qiang Jin Jie Hou Guangbo Ge Ling Yang | 2018 | Acta Pharmaceutica Sinica B2018，8，5： | 14 |
| 10 | IL-10-producing regulatory B cells restrain the T follicular helper cell response in primary Sjögren’s syndrome显示文摘Increased numbers of T follicular helper(Tfh)cells have been implicated in the development of autoimmune diseases including primary Sjögren’s syndrome(pSS),but how the Tfh cell response is regulated during autoimmune pathogenesis remains largely unclear.Here,we first found negative correlations between IL-10^(+)regulatory B(Breg)cell numbers and Tfh cell responses and disease activity in patients with pSS and mice with experimental Sjögren’s syndrome(ESS).Moreover,we detected high expression of IL-10 receptor on Tfh cells and their precursors in both humans and mice.In culture,IL-10 suppressed human and murine Tfh cell differentiation by promoting STAT5 phosphorylation.By using an adoptive transfer approach and two-photon live imaging,we found significantly increased numbers of Tfh cells with enhanced T cell homing into B cell follicles in the draining cervical lymph nodes of RAG-2−/−mice transferred with IL-10-deficient B cells during ESS development compared with those of RAG-2−/−mice transferred with wild-type B cells.In ESS mice,CD19^(+)CD1d^(hi)CD5^(+)Breg cells with decreased IL-10 production exhibited severely impaired suppressive effects on T cell proliferation.Consistently,CD19^(+)CD24^(+)CD38^(hi) Breg cells from pSS patients showed significantly reduced IL-10 production with defective inhibitory function in the suppression of autologous Tfh cell expansion.Furthermore,the adoptive transfer of IL-10-producing Breg cells markedly suppressed the Tfh cell response and ameliorated ESS progression in ESS mice.Together,these findings demonstrate a critical role for IL-10-producing Breg cells in restraining the effector Tfh cell response during pSS development. | Xiang Lin Xiaohui Wang Fan Xiao Kongyang Ma Lixiong Liu Xiaoqi Wang Dong Xu Fei Wang Xiaofei Shi Dongzhou Liu Yan Zhao Liwei Lu | 2019 | Cellular & Molecular Immunology2019，16，12： | 13 |

| 12 | Olfactory ecto-mesenchymal stem cell-derived exosomes ameliorate murine Sjögren’s syndrome by modulating the function of myeloid-derived suppressor cells显示文摘Sjögren’s syndrome(SS)is a systemic autoimmune disease characterized by progressive inflammation and tissue damage in salivary glands and lacrimal glands.Our previous studies showed that myeloid-derived suppressor cells(MDSCs)exhibited impaired immunosuppressive function during disease progression in patients with SS and mice with experimental Sjögren’s syndrome(ESS),but it remains unclear whether restoring the function of MDSCs can effectively ameliorate the development of ESS.In this study,we found that murine olfactory ecto-mesenchymal stem cell-derived exosomes(OE-MSC-Exos)significantly enhanced the suppressive function of MDSCs by upregulating arginase expression and increasing ROS and NO levels.Moreover,treatment with OE-MSC-Exos via intravenous injection markedly attenuated disease progression and restored MDSC function in ESS mice.Mechanistically,OE-MSC-Exo-secreted IL-6 activated the Jak2/Stat3 pathway in MDSCs.In addition,the abundant S100A4 in OE-MSC-Exos acted as a key factor in mediating the endogenous production of IL-6 by MDSCs via TLR4 signaling,indicating an autocrine pathway of MDSC functional modulation by IL-6.Taken together,our results demonstrated that OE-MSC-Exos possess therapeutic potential to attenuate ESS progression by enhancing the immunosuppressive function of MDSCs,possibly constituting a new strategy for the treatment of Sjögren’s syndrome and other autoimmune diseases. | Ke Rui Yue Hong Qiugang Zhu Xiaofei Shi Fan Xiao Hailong Fu Qing Yin Yida Xing Xinfeng Wu Xiaodan Kong Huaxi Xu Jie Tian Shengjun Wang Liwei Lu | 2021 | Cellular & Molecular Immunology2021，18，2： | 12 |

| 14 | Output Characteristics of a Series Three-port Axial Piston Pump显示文摘Driving a hydraulic cylinder directly by a closed-loop hydraulic pump is currently a key research area in the field of electro-hydraulic control technology,and it is the most direct means to improve the energy efficiency of an electro-hydraulic control system.So far,this technology has been well applied to the pump-controlled symmetric hydraulic cylinder.However,for the differential cylinder that is widely used in hydraulic technology,satisfactory results have not yet been achieved,due to the asymmetric flow constraint.Therefore,based on the principle of the asymmetric valve controlled asymmetric cylinder in valve controlled cylinder technology,an innovative idea for an asymmetric pump controlled asymmetric cylinder is put forward to address this problem.The scheme proposes to transform the oil suction window of the existing axial piston pump into two series windows.When in use,one window is connected to the rod chamber of the hydraulic cylinder and the other is linked with a low-pressure oil tank.This allows the differential cylinders to be directly controlled by changing the displacement or rotation speed of the pumps.Compared with the loop principle of offsetting the area difference of the differential cylinder through hydraulic valve using existing technology,this method may simplify the circuits and increase the energy efficiency of the system.With the software SimulationX,a hydraulic pump simulation model is set up,which examines the movement characteristics of an individual piston and the compressibility of oil,as well as the flow distribution area as it changes with the rotation angle.The pump structure parameters,especially the size of the unloading groove of the valve plate,are determined through digital simulation.All of the components of the series arranged three distribution-window axial piston pump are designed,based on the simulation analysis of the flow pulse characteristics of the pump,and then the prototype pump is made.The basic characteristics,such as the pressure,flow and noise of the pumps under different rotation speeds,are measured on the test bench.The test results verify the correctness of the principle.The proposed research lays a theoretical foundation for the further development of a new pump-controlled cylinder system. | ZHANG Xiaogang QUAN Long YANG Yang WANG Chengbin YAO Liwei | 2012 | Chinese Journal of Mechanical Engineering2012，25，3： | 10 |
| 15 | Metal release/accumulation during the decomposition of Potamogeton crispus in a shallow macrophytic lake显示文摘Changes in metal concentrations in the litter of Potamogeton crispus were monitored during a consecutive 40-day in situ decomposition experiment using the litterbag method.The accumulation index was calculated and used to indicate the changes in the metals in litter.The results showed that the concentrations of Al,Cd,Cr,Fe,Mn,and Pb in litter increased significantly during the decomposition,while Cu and Zn concentrations decreased dramatically.Significant positive correlations were found between the concentrations of Al,Cr,Fe,and Mn and between Cu and Zn.Moreover,Cu and Zn both negatively correlated with Al and Fe.The remaining dry mass was negatively correlated with Al and Fe concentrations but positively correlated with Cu and Zn concentrations.Generally the accumulation index values of metals other than Al were less than one,indicating that the litter of P.crispus acted as a source of metals to the surrounding water body.Al was the only metal that showed continuous net accumulation in litter.The net accumulation of Fe and Mn in litter during the last 10 days of the experiment may indicate the precipitation of Feand Mn-oxides.It was estimated that 160 g/m^2(dry weight)P.crispus was decomposed in40 days.This was equivalent to releasing the following amounts of metals:0.01 mg Cd,0.03 mg Cr,0.71 mg Cu,0.55 mg Mn,0.02 mg Pb and 13.8 mg Zn into surrounding water,and accumulating 149 mg Al and 11 mg Fe,in a 1 m^2 area. | Huanguang Deng Ju Zhang Shiyue Chen Liwei Yang Dongqi Wang Shiyong Yu | 2016 | Journal of Environmental Sciences2016，28，4： | 10 |

| 17 | Epigenetic regulation in B-cell maturation and its dysregulation in autoimmunity显示文摘B cells have a critical role in the initiation and acceleration of autoimmune diseases, especially those mediated byautoantibodies. In the peripheral lymphoid system, mature B cells are activated by self or/and foreign antigens andsignals from helper T cells for differentiating into either memory B cells or antibody-producing plasma cells.Accumulating evidence has shown that epigenetic regulations modulate somatic hypermutation and class switchDNA recombination during B-cell activation and differentiation. Any abnormalities in these complex regulatoryprocesses may contribute to aberrant antibody production, resulting in autoimmune pathogenesis such as systemiclupus erythematosus. Newly generated knowledge from advanced modern technologies such as next-generationsequencing, single-cell sequencing and DNA methylation sequencing has enabled us to better understand B-cellbiology and its role in autoimmune development. Thus this review aims to summarize current research progress inepigenetic modifications contributing to B-cell activation and differentiation, especially under autoimmuneconditions such as lupus, rheumatoid arthritis and type 1 diabetes. | Haijing Wu Yaxiong Deng Yu Feng Di Long Kongyang Ma Xiaohui Wang Ming Zhao Liwei Lu Qianjin Lu | 2018 | Cellular & Molecular Immunology2018，15，7： | 10 |
| 18 | A measurement-driven adaptive probability hypothesis density filter for multitarget tracking显示文摘This paper studies the dynamic estimation problem for multitarget tracking. A novel gating strategy that is based on the measurement likelihood of the target state space is proposed to improve the overall effectiveness of the probability hypothesis density(PHD) filter. Firstly, a measurement-driven mechanism based on this gating technique is designed to classify the measurements. In this mechanism, only the measurements for the existing targets are considered in the update step of the existing targets while the measurements of newborn targets are used for exploring newborn targets. Secondly, the gating strategy enables the development of a heuristic state estimation algorithm when sequential Monte Carlo(SMC) implementation of the PHD filter is investigated, where the measurements are used to drive the particle clustering within the space gate.The resulting PHD filter can achieve a more robust and accurate estimation of the existing targets by reducing the interference from clutter. Moreover, the target birth intensity can be adaptive to detect newborn targets, which is in accordance with the birth measurements. Simulation results demonstrate the computational efficiency and tracking performance of the proposed algorithm. | Si Weijian Wang Liwei Qu Zhiyu | 2015 | Chinese Journal of Aeronautics2015，28，6： | 9 |
| 19 | A bioactive injectable self-healing anti-inflammatory hydrogel with ultralong extracellular vesicles release synergistically enhances motor functional recovery of spinal cord injury显示文摘The repair and motor functional recovery after spinal cord injury(SCI)remains a worldwide challenge.The inflammatory microenvironment is one of main obstacles on inhibiting the recovery of SCI.Using mesenchymal stem cells(MSCs)derived extracellular vesicles to replace MSCs transplantation and mimic cell paracrine secretions provides a potential strategy for microenvironment regulation.However,the effective preservation and controlled release of extracellular vesicles in the injured spinal cord tissue are still not satisfied.Herein,we fabricated an injectable adhesive anti-inflammatory F127-polycitrate-polyethyleneimine hydrogel(FE)with sustainable and long term extracellular vesicle release(FE@EVs)for improving motor functional recovery after SCI.The orthotopic injection of FE@EVs hydrogel could encapsulate extracellular vesicles on the injured spinal cord,thereby synergistically induce efficient integrated regulation through suppressing fibrotic scar formation,reducing inflammatory reaction,promoting remyelination and axonal regeneration.This study showed that combining extracellular vesicles into bioactive multifunctional hydrogel should have great potential in achieving satisfactory locomotor recovery of central nervous system diseases. | Chenggui Wang Min Wang Kaishun Xia Jingkai Wang Feng Cheng Kesi Shi Liwei Ying Chao Yu Haibin Xu Shining Xiao Chengzhen Liang Fangcai Li Bo Lei Qixin Chen | 2021 | Bioactive Materials2021，6，8： | 9 |
| 20 | Adsorption performances and refrigeration application of adsorption working pair of CaCl_2-NH_3显示文摘The adsorption performance of CaCl2-NH3 is studied under the condition of different expansion spaces for adsorbent, and the relationships between adsorption performance of CaCl2-NH3 and the phenomena of swelling and agglomeration during adsorption are researched. It is found that the performance stability is related to the ratio of expansion space to the volume of adsorbent ras, and the performance attenuation is serious in the case of large ras. Severe adsorption hysteresis exists in the process of adsorption and desorption at the same evaporating and condensing temperatures, which is related to the stability constant of chemical reaction. This phenomenon cannot be explained by the theory of physical adsorption. Moderate agglomeration will be beneficial to the formation of ammoniate complex; the magnitude of expansion space will affect adsorption performance. Analysis shows that the activated energy needed in the process of adsorption for the sample with ras of 2:1 is less than that for the sample with ras of 3:1. The refrigeration performance of CaCl2-NH3 is predicted from experiments. The cooling capacity of one adsorption cycle is about 945.4 kJ/kg for the adsorbent with an ras of 2:1 at the evaporating temperature of 0℃. | WANG Liwei WANG Ruzhu WU Jingyi WANG Kai | 2004 | Science China(Technological Sciences)2004，47，2： | 9 |
