| 1 | NLRP3-dependent pyroptosis is required for HIV-1 gp120- induced neuropathology显示文摘The human immunodeficiency virus-1(HIV-1)envelope protein gp120 is the major contributor to the pathogenesis of HIVassociated neurocognitive disorder(HAND).Neuroinflammation plays a pivotal role in gp120-induced neuropathology,but how gp120 triggers neuroinflammatory processes and subsequent neuronal death remains unknown.Here,we provide evidence that NLRP3 is required for gp120-induced neuroinflammation and neuropathy.Our results showed that gp120-induced NLRP3-dependent pyroptosis and IL-1βproduction in microglia.Inhibition of microglial NLRP3 inflammasome activation alleviated gp120-mediated neuroinflammatory factor release and neuronal injury.Importantly,we showed that chronic administration of MCC950,a novel selective NLRP3 inhibitor,to gp120 transgenic mice not only attenuated neuroinflammation and neuronal death but also promoted neuronal regeneration and restored the impaired neurocognitive function.In conclusion,our data revealed that the NLRP3 inflammasome is important for gp120-induced neuroinflammation and neuropathology and suggest that NLRP3 is a potential novel target for the treatment of HAND. | Xiaolong He Weijun Yang Zhijie Zeng Yi Wei Jie Gao Bao Zhang Li Li Liqun Liu Yu Wan Qing Zeng Zelong Gong Liting Liu Hanyun Zhang Yubin Li Shaojie Yang Tongtong Hu Lixian Wu Eliezer Masliah Shenghe Huang Hong Cao | 2020 | Cellular & Molecular Immunology2020，17，3： | 11 |
| 2 | Enhancement of Fenton oxidation for removing organic matter from hypersaline solution by accelerating ferric system with hydroxylamine hydrochloride and benzoquinone显示文摘Fenton oxidation is generally inhibited in the presence of a high concentration of chloride ions.This study investigated the feasibility of using benzoquinone(BQ) and hydroxylamine hydrochloride(HA) as Fenton enhancers for the removal of glycerin from saline water under ambient temperature by accelerating the ferric system.It was found that organics removal was not obviously affected by chloride ions of low concentration(less than 0.1 mol/L),while the mineralization rate was strongly inhibited in the presence of a large amount of chloride ions.In addition,ferric hydrolysis-precipitation was significantly alleviated in the presence of HA and BQ,and HA was more effective in reducing ferric ions into ferrous ions than HA,while the H_2O_2 decomposition rate was higher in the BQ-Fenton system.Electron spin resonance analysis revealed that OH production was reduced in high salinity conditions,while it was enhanced after the addition of HA and BQ(especially HA).This study provided a possible solution to control and alleviate the inhibitory effect of chloride ions on the Fenton process for organics removal. | Siwei Peng Weijun Zhang Jie He Xiaofang Yang Dongsheng Wang Guisheng Zeng | 2016 | Journal of Environmental Sciences2016，28，3： | 10 |
| 3 | Topic enhanced deep structured semantic models for knowledge base question answering显示文摘Knowledge Base Question Answering(KBQA) is a hot research topic in natural language processing(NLP). The most challenging problem in KBQA is how to understand the semantic information of natural language questions and how to bridge the semantic gap between the natural language questions and the structured fact triples in knowledge base. This paper focuses on simple questions which can be answered by a single fact triple in knowledge base. We propose a topic enhanced deep structured semantic model for KBQA. The proposed method considers the task of KBQA as a matching problem between questions and the subjects and predicates in knowledge base. And the proposed model consists of two stages to match the subjects and predicates, respectively. In the first stage, we propose a Convolutional based Topic Entity Extraction Model(CTEEM) to extract topic entities mentioned in questions. With the extracted entities, we can retrieve the relevant candidate fact triples from knowledge base and obviously decrease the amount of noising candidates. In the second stage, we employ Deep Structured Semantic Models(DSSMs) to compute the semantic relevant score between questions and predicates in the candidates. And we combine the semantic level and the lexical level scores to rank the candidates. We evaluate the proposed method on KBQA dataset released by NLPCC-ICCPOL 2016. The experimental results show that our proposed method achieves the third place among the 21 submitted systems.Furthermore, we also extend the DSSM by using Bi LSTM and integrate a convolutional structure on the top of Bi LSTM layers. Our experimental results show that the extension models can further improve the performance. | Zhiwen XIE Zhao ZENG Guangyou ZHOU Weijun WANG | 2017 | Science China(Information Sciences)2017，60，11： | 10 |
| 4 | Characteristics of Upper Mantle Activity in the South China Sea Region and the Indochina Mantle Plume显示文摘According to computed results of the mantle traction field beneath the lithosphere based on satellite-modelled gravity anomalies of different degrees, it has been revealed that the three types of mantle convection on different scales existing in the South China Sea region is the key factor controlling the geodynamics. The mantle convection models on large and middle scales have been proved by natural seismic S-wave tomographic data and interpreted by using the present mantle plume concept In consideration of other relevant geological and geophysical data, the authors put emphasis on discussing the expression form, origin and age of the Indochina mantle plume and its important effect on the conversion of organic matter and hydrocarbon accumulation in Cenozoic basins. | WU Nengyou ZENG Weijun LI Zhenwu CHEN Yizhong WEN Xiwen DU Deli LI Guosheng | 1999 | Acta Geologica Sinica(English Edition)1999，73，4： | 6 |
| 5 | Acrylamide exposure impairs blood-cerebrospinal fluid barrier function显示文摘Previous studies show that chronic acrylamide exposure leads to central and peripheral neuropathy. However, the underlying mechanisms remained unclear. In this study, we examined the permeability of the blood-cerebrospinal fluid barrier, and its ability to secrete transthyretin and transport leptin of rats exposed to acrylamide for 7, 14, 21 or 28 days. Transthyretin levels in cerebrospinal fluid began to decline on day 7 after acrylamide exposure. The sodium fluorescein level in cerebrospinal fluid was increased on day 14 after exposure. Evans blue concentration in cerebrospinal fluid was increased and the cerebrospinal fluid/serum leptin ratio was decreased on days 21 and 28 after exposure. In comparison, the cerebrospinal fluid/serum albumin ratio was increased on day 28 after exposure. Our findings show that acrylamide exposure damages the blood-cerebrospinal fluid barrier and impairs secretory and transport functions. These changes may underlie acrylamide-induced neurotoxicity. | Xue Yao Licheng Yan Lin Yao Weijun Guan Fanxu Zeng Fuyuan Cao Yanshu Zhang | 2014 | Neural Regeneration Research2014，9，5： | 4 |
| 6 | Chaperone-mediated autophagy:roles in neuroprotection显示文摘Chaperone-mediated autophagy(CMA), one of the main pathways of lysosomal proteolysis, is characterized by the selective targeting and direct translocation into the lysosomal lumen of substrate proteins containing a targeting motif biochemically related to the pentapeptide KFERQ. Along with the other two lysosomal pathways, macro- and micro-autophagy, CMA is essential for maintaining cellular homeostasis and survival by selectively degrading misfolded, oxidized, or damaged cytosolic proteins. CMA plays an important role in pathologies such as cancer, kidney disorders, and neurodegenerative diseases. Neurons are post-mitotic and highly susceptible to dysfunction of cellular quality-control systems. Maintaining a balance between protein synthesis and degradation is critical for neuronal functions and homeostasis. Recent studies have revealed several new mechanisms by which CMA protects neurons through regulating factors critical for their viability and homeostasis. In the current review, we summarize recent advances in the understanding of the regulation and physiology of CMA with a specific focus on its possible roles in neuroprotection. | Zhibiao Cai Weijun Zeng Kai Tao Zhen E Bao Wang Qian Yang | 2015 | Neuroscience Bulletin2015，31，4： | 4 |
| 7 | Nanomaterials toward the treatment of Alzheimer's disease:Recent advances and future trends显示文摘Alzheimer’s disease(AD)is a progressive and fatal neurodegenerative condition and the most prevalent cause of dementia.This disease is characterized by progressive cognitive impairment.The prevalence of AD is currently affecting more than 35 million people and is rising worldwide.No efficient therapy is currently available due to low drug potency and a number of various obstacles to delivery.Recent nanotechnological advancements have the potential to offer promising therapeutic options.Progress on nanomaterials as well as their applications in biomedicine is receiving increasing attention,especially the advantages of nanomaterial-based drug delivery systems.The aim of this review is to comprehensively summarize the latest developments in nanomaterial-based strategies for AD treatment,including nanoparticles,liposomes and other options for the delivery of therapeutic compounds and scaffolds for cell delivery strategies.Future research directions are also proposed.We hope this review can provide important information to guide the future development of nanomaterials in AD treatment. | Huihui Zeng Yujie Qi Zheyu Zhang Chuntai Liu Weijun Peng Yi Zhang | 2021 | Chinese Chemical Letters2021，32，6： | 2 |
| 8 | CO flux of soil respiration in natural recovering karst abandoned farmland in Southwest China显示文摘To estimate carbon sequestration potential in the karst area,soil respiration in a natural recovering karst abandoned farmland in Shawan,Puding,Guizhou,southwest China was continuously and automatically monitored for more than two years.The results show that the CO2flux of soil respiration(2.63±1.89 lmol m^-2s-^1)is higher in the karst area than in non-karst areas under similar conditions but that regional value(1.32 lmol m-2s-1)is lower because of larger rock fragment coverage(~50%).A the same time,the temperature sensitivity of soil respiration(Q10)in this study area is significantly higher than that of non-karst areas under similar conditions.Soil respiration has an obvious temporal variation,which is reflected in a significant exponential relationship between soil respiration and soil temperature,but the relationship between soil respiration and soil moisture is very complex.Especially soil respiration has an obvious spatial variation,which is likely affected by different diffusion or water-rock reaction processes. | Yanwei Wang Weijun Luo Guangneng Zeng Hanling Yang Meifang Wang Yina Lyu Anyun Cheng Lin Zhang Xianli Cai Jia Chen Shijie Wang | 2020 | Acta Geochimica2020，39，4： | 2 |
| 9 | Two Ultraviolet Radiation Datasets that Cover China显示文摘Ultraviolet(UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes. | Hui LIU Bo HU Yuesi WANG Guangren LIU Liqin TANG Dongsheng JI Yongfei BAI Weikai BAO Xin CHEN Yunming CHEN Weixin DING Xiaozeng HAN Fei HE Hui HUANG Zhenying HUANG Xinrong LI Yan LI Wenzhao LIU Luxiang LIN Zhu OUYANG Boqiang QIN Weijun SHEN Yanjun SHEN Hongxin SU Changchun SONG Bo SUN Song SUN Anzhi WANG Genxu WANG Huimin WANG Silong WANG Youshao WANG Wenxue WEI Ping XIE Zongqiang XIE Xiaoyuan YAN Fanjiang ZENG Fawei ZHANG Yangjian ZHANG Yiping ZHANG Chengyi ZHAO Wenzhi ZHAO Xueyong ZHAO Guoyi ZHOU Bo ZHU | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |
| 10 | Mechanobiologically optimized Ti-35Nb-2Ta-3Zr improves load transduction and enhances bone remodeling in tilted dental implant therapy显示文摘The tilted implant with immediate function is increasingly used in clinical dental therapy for edentulous and partially edentulous patients with excessive bone resorption and the anatomic limitations in the alveolar ridge.However,peri-implant cervical bone loss can be caused by the stress shielding effect.Herein,inspired by the concept of“materiobiology”,the mechanical characteristics of materials were considered along with bone biology for tilted implant design.In this study,a novel Ti-35Nb-2Ta-3Zr alloy(TNTZ)implant with low elastic modulus,high strength and favorable biocompatibility was developed.Then the human alveolar bone environment was mimicked in goat and finite element(FE)models to investigate the mechanical property and the related peri-implant bone remodeling of TNTZ compared to commonly used Ti-6Al-4V(TC4)in tilted implantation under loading condition.Next,a layer-by-layer quantitative correlation of the FE and X-ray Microscopy(XRM)analysis suggested that the TNTZ implant present better mechanobiological characteristics including improved load transduction and increased bone area in the tilted implantation model compared to TC4 implant,especially in the upper 1/3 region of peri-implant bone that is“lower stress”.Finally,combining the static and dynamic parameters of bone,it was further verified that TNTZ enhanced bone remodeling in“lower stress”upper 1/3 region.This study demonstrates that TNTZ is a mechanobiological optimized tilted implant material that enhances load transduction and bone remodeling. | Chuanyuan Mao Weijun Yu Min Jin Yingchen Wang Xiaoqing Shang Lu Lin Xiaoqin Zeng Liqiang Wang Eryi Lu | 2022 | Bioactive Materials2022，7，10： | 1 |

| 13 | Terahertz wave modulation properties of thermally processed BST/PZT ferroelectric photonic crystals显示文摘BST(Ba0.5Sr0.5TiO3)/PZT(Pb0.52Zr0.48TiO3)photonic crystals were fabricated by magnetron sputtering and annealed at 620℃-700℃.By controlling the crystallinity and the oxygen vacancies of the ferroelectric photonic crystals,the optically and electrically controllable terahertz wave modulations were realized.The variation in refractive index of the 680℃ anncaled sample showed the highest modulation to the optical pump and increased to 11.9 due to the highest absorption near 532 nm.In the optical pump,the electrons from Ti^3+2p3/2 ions could be stimulated and captured by Ti^4+2p3/2 ions,and the ratio of Ti^3+/Ti^4+ observed increased with the increasing annealing temperature,indicating the increasing oxygen vacancies concentration,which increased the 532 nm optical absorption and contributed to the improved optical modulation.The excess Pb migrating to the surface at higher annealing temperature might be one reason for the degradation of optical modulation.The increasing polarization and leakage current could contribute to the increasing permittivity and loss with the increasing annealing temperature.Two different results were observed on the sample annealed at 680℃ when the order of applying external optical and electric fields was changed,due to the different migration mechanisms of excited carriers.This work provides a potentially effective approach to fabricate THz sensing,imaging,and communi-cations devices with multi-function in the modulation of optical and electric multi-fields. | YING ZENG WEIJUN WANG FURI LING JIANQUAN YAO | 2020 | Photonics Research2020，8，6： | 0 |
| 14 | Large magnetocaloric effect and magnetoresistance in ErNi single crystal显示文摘The magnetic properties,magnetocaloric effect and magnetoresistance in Er Ni single crystal have been investigated in detail.With decreasing temperature,Er Ni single crystal undergoes two successive magnetic transitions:a paramagnetic to ferromagnetic transition at T_(C)=11 K and a spin-reorientation transition at TS_(R)=5 K.Meanwhile,a sharp field-induced metamagnetic transition is observed below the T_(C)along the a axis.Er Ni single crystal possesses a giant magnetocaloric effect around T_(C).The maximum magnetic entropy change is-36.1 J(kg K)^(-1)along the a axis under the field change of 0-50 k Oe.In particular,the rotating magnetocaloric effect in Er Ni single crystal reaches its maximum under a relatively low field,and the maximum rotating entropy change with a value of 9.3 J(kg K)^(-1)is obtained by rotating the applied field from the[011]to[100]directions under 13 k Oe.These results suggest that Er Ni could be a promising candidate for magnetic refrigeration working at liquid-helium temperature region.Moreover,a complicated transport behavior is uncovered in Er Ni single crystal,which is attributed to the complex magnetic states and magnetic polaronic effect.Both positive and negative magnetoresistance are observed.A considerable large magnetoresistance with the value of-34.5%is acquired at 8 K under50 k Oe when the field is along the[100]direction. | Xuanwei Zhao Xianming Zheng Xiaohua Luo Fei Gaod Hai Zeng Guang Yu Sajjad Ur Rehman Changcai Chen Shengcan Ma Weijun Ren Zhenchen Zhong | 2021 | Journal of Materials Science & Technology2021，，27： | 0 |

| 16 | Effects of Climate Factors in Greenhouses on the Growth Development and Quality of Houttuynia cordata Thunb.显示文摘[Objectives]This study was conducted to demonstrate whether greenhouse planting can solve the problem of insufficient supply of fresh H.cordata Thunb.in winter and spring.[Methods]The effects of meteorological factors on the growth and quality of H.cordata Thunb.were analyzed.[Results]The highest temperature and lowest temperature in greenhouses were 6-12℃and 5-10℃higher than those in the open fields,respectively,and the average temperature difference between the greenhouses and the open fields was large in the early stage,but small in the late stage.The effective accumulated temperature≥10℃was 3463℃in the greenhouses and 2046℃in the open fields.Although the humidity in the open fields was higher than that in the greenhouses,the humidity in the greenhouses was relatively stable and that in the open field changed greatly.The light intensity of the greenhouses was lower than that of the open fields.In terms of the periods from film covering day to seedling emergence,seedling emergence to full emergence,and full emergence to crop closure,greenhouse planting was shortened by 47,11,and 5 d,respectively,compared with open field planting,but the period from crop closure to flowering was extended by 40 d.The plant height of the plants planted in the greenhouses reached 0.1 cm on January 7,while those planted in the open fields did not have seedlings until February 25,and the plant height,daily growth rate,yield and effective components in volatile oil of the plants planted in the greenhouses were significantly higher than those planted in the open fields.The growth,development and quality of H.cordata Thunb.reached the extremely significant or significant level with temperature,but had no significant correlation with humidity and light intensity,indicating that temperature had the greatest impact on the growth,development and quality of H.cordata Thunb.when planted in the greenhouses.[Conclusions]This study provides a theoretical basis for protected cultivation and explores new planting methods for the further development of its industry. | Weijun ZENG Xiyao ZENG Jun ZHONG | 2022 | Agricultural Biotechnology2022，11，6： | 0 |
| 17 | Combined linkage and association mapping reveals two major QTL for stripe rust adult plant resistance in Shaanmai 155 and their haplotype variation in common wheat germplasm显示文摘The development and deployment of diverse resistance sources in new wheat cultivars underpin the durable control of stripe rust.In the present study,two loci for adult plant resistance(APR),QYr SM155.1 and QYr SM155.2,were identified in the Chinese wheat breeding line Shaanmai 155.QYr SM155.1 was mapped to a 3.0-c M interval between the single-nucleotide polymorphism(SNP)markers AX-109583610 and AX-110907562 on chromosome arm 2 BL.QYr SM155.2 was mapped to a 2.1-c M interval flanked by the SNP markers AX-110378556 and AX-86173526 on chromosome arm 7 AS.A genome-wide association study was used to identify markers associated with APR in a panel of 411 spring wheat lines.Thirteen and 11 SNPs were significantly associated with QYr SM155.1 and QYr SM155.2,respectively,corresponding to physical intervals of 653.75–655.52 Mb on 2 BL and 81.63–83.93 Mb on7 AS.To characterize the haplotype variation and the distribution of these QTL,haplotype analysis was performed based on these SNPs in an independent panel of 1101 worldwide wheat accessions.Three major haplotypes(2 B_h1,2 B_h2,and 2 B_h3)for QYr SM155.1 and four major haplotypes(7 A_h1,7 A_h2,7 A_h3,and 7 A_h4)for QYr SM155.2 were identified.Accessions individually harboring QYr SM155.1_h1 and QYr SM155.2_h1 haplotypes and their combination displayed resistance.Additional assays of 1306 current Chinese cultivars and breeding lines using markers flanking QYr SM155.1 and QYr SM155.2 indicated that the resistance haplotypes of the two QTL were present in respectively 1.45%and 14.16%of lines.Increasing resistance haplotype frequencies at these two loci using marker-assisted selection should benefit wheat production in China. | Cai’e Zhou Dan Liu Xu Zhang Qimeng Wu Shengjie Liu Qingdong Zeng Qilin Wang Changfa Wang Chunlian Li Ravi PSingh Sridhar Bhavani Zhensheng Kang Dejun Han Weijun Zheng Jianhui Wu | 2022 | The Crop Journal2022，10，3： | 0 |
