| 1 | Backstepping design of missile guidance and control based on adaptive fuzzy sliding mode control显示文摘This paper presents an integrated missile guidance and control law based on adaptive fuzzy sliding mode control. The integrated model is formulated as a block-strict-feedback nonlinear system, in which modeling errors, unmodeled nonlinearities, target maneuvers, etc. are viewed as unknown uncertainties. The adaptive nonlinear control law is designed based on backstepping and sliding mode control techniques. An adaptive fuzzy system is adopted to approximate the coupling nonlinear functions of the system, and for the uncertainties, we utilize an online-adaptive control law to estimate the unknown parameters. The stability analysis of the closed-loop system is also conducted. Simulation results show that, with the application of the adaptive fuzzy sliding mode control, small miss distances and smooth missile trajectories are achieved, and the system is robust against system uncertainties and external disturbances. | Ran Maopeng Wang Qing Hou Delong Dong Chaoyang | 2014 | Chinese Journal of Aeronautics2014,27,3: | 32 |
| 2 | Rhizospheric microbial communities are driven by Panax ginseng at different growth stages and biocontrol bacteria alleviates replanting mortality显示文摘The cultivation of Panax plants is hindered by replanting problems, which may be caused by plantdriven changes in the soil microbial community. Inoculation with microbial antagonists may efficiently alleviate replanting issues. Through high-throughput sequencing, this study revealed that bacterial diversity decreased,whereas fungal diversity increased, in the rhizosphere soils of adult ginseng plants at the root growth stage under different ages. Few microbial community, such as Luteolibacter, Cytophagaceae, Luteibacter, Sphingomonas,Sphingomonadaceae, and Zygomycota, were observed; the relative abundance of microorganisms, namely,Brevundimonas, Enterobacteriaceae, Pandoraea, Cantharellales, Dendryphion, Fusarium, and Chytridiomycota,increased in the soils of adult ginseng plants compared with those in the soils of 2-year-old seedlings. Bacillus subtilis 50-1, a microbial antagonist against the pathogenic Fusarium oxysporum, was isolated through a dual culture technique. These bacteria acted with a biocontrol efficacy of 67.8%. The ginseng death rate and Fusarium abundance decreased by 63.3% and 46.1%, respectively, after inoculation with B. subtilis 50-1. Data revealed that microecological degradation could result from ginseng-driven changes in rhizospheric microbial communities;these changes are associated with the different ages and developmental stages of ginseng plants. Biocontrol using microbial antagonists alleviated the replanting problem. | Linlin Dong Jiang Xu Lianjuan Zhang Ruiyang Cheng Guangfei Wei He Su Juan Yang Jun Qian Ran Xu Shilin Chen | 2018 | Acta Pharmaceutica Sinica B2018,8,2: | 27 |
| 3 | Programmed death-1 expression is associated with the disease status in hepatitis B virus infection显示文摘AIM: To define the potential role of programmed death-1/programmed death-ligand (PD-1/PD-L) pathway in different hepatitis B virus (HBV) infection disease status; we examined the expression of PD-1 on antigen specific CD8+ T cells in peripheral blood of patients with chronic hepatitis B (CHB) and acute exacerbation of hepatitis B (AEHB) infection. METHODS: The PD-1 level on CD8+ T lymphocytes and the number of HBV specifi c CD8+ T lymphocytes in patients and healthy controls (HCs) were analyzed by staining with pentameric peptide-human leukocyte antigen2 (HLA2) complexes combined with flow cytometry. Real-time quantitative polymerase chain reaction (PCR) was used to measure the serum HBV-DNA levels. RESULTS: The level of PD-1 expression on total CD8+ T cells in CHB patients (13.86% ± 3.38%) was significantly higher than that in AEHB patients (6.80%± 2.19%, P < 0.01) and healthy individuals (4.63% ± 1.23%, P < 0.01). Compared to AEHB patients (0.81% ± 0.73%), lower frequency of HBV-specific CD8+ T cells was detected in chronic hepatitis B patients (0.37% ± 0.43%, P < 0.05). There was an inverse correlation between the strength of HBV-specific CD8+ T-cell response and the level of PD-1 expression. Besides, there was a significant positive correlation between HBV viral load and the percentage of PD-1 expression on CD8+ T cells in CHB and AEHB subjects (R = 0.541, P < 0.01). However, PD-1 expression was not associated with disease flare-ups as indicated by alanine aminotransferase (ALT) levels (R = 0.066, P > 0.05). CONCLUSION: Our results confirm previous reports that HBV specific CD8+ T-cell response in the peripheral blood is more intense in patients with AEHB than in chronic hepatitis B with persistent viral infection. Moreover, there is a negative correlation between the level of PD-1 and the intensity of virus specific CD8+T cell response. | Plan Ye Zhi-Hong Weng Shu-Ling Zhang Jian-Ao Zhang Lei Zhao Ji-Hua Dong Sheng-Hua Jie Ran Pang Rong-Hua Wei | 2008 | World Journal of Gastroenterology2008,14,28: | 25 |
| 4 | Effects of pH and particle size on kinetics of nitrobenzene reduction by zero-valent iron显示文摘Nitrobenzene has been considered as a significant groundwater contaminant due to its wide usage in explosives, insecticides, herbicides, pharmaceuticals and dyes. Nitrobenzene is of environmental concern because of its toxicity. In the presence of zero-valent iron (ZVI), reduction of the nitro group is the dominant transformation process for nitrobenzene. A series of experiments were carried out to investigate the kinetics of nitrobenzene reduction by ZVI and the effects of pH and ZVI particle size on nitrobenzene removal in groundwater. The results indicated that nitrobenzene could be reduced to aniline by ZVI; the reduction of nitrobenzene by ZVI followed a pseudo first-order kinetics; the observed nitrobenzene reduction rate constant (k obs ) was 0.0006 min 1 and the half-life of nitrobenzene (t 1/2 ) was 115.5 min; the mass balance achieved 87.5% for nitrobenzene reduction by the 1 mm ZVI particle and the final removal efficiency was 80.98%. In addition, the pH and ZVI particle size were found to exhibit significant influences on the nitrobenzene reduction. The observed nitrobenzene reduction rate constant linearly decreased with increase pH and the data fitted on polynomial regression equation for the observed nitrobenzene reduction rate constant and ZVI particle size. Therefore, use of ZVI based permeable reactive barrier technology to remedy nitrobenzene contaminated groundwater was feasible. | Jun Dong Yongsheng Zhao Ran Zhao Rui Zhou | 2010 | Journal of Environmental Sciences2010,22,11: | 23 |

| 6 | Colorectal cancer in inflammatory bowel disease:The risk,pathogenesis,prevention and diagnosis显示文摘Patients with inflammatory bowel disease(IBD)are at increased risk for developing colorectal cancer(CRC),although the overall incidence of IBD-associated CRC has been diminishing in recent decades in western countries.As demonstrated in previous studies,the risk of CRC in IBD increases with longer duration,extent of colitis,a familial history of CRC,coexistent primary sclerosing cholangitis,and the degree of inflammation.The pathogenesis of CRC in IBD is poorly understood.Similar to sporadic CRC,IBD-associated CRC is a consequence of sequential episodes of genomic alteration.Multiple inter-related pathways,including immune response by mucosal inflammatory mediators,oxidative stress,and intestinal microbiota,are also involved the pathogenesis of IBD-associated CRC.Continuing colonic inflammation appears to be a factor in the development of CRC;therefore,anti-inflammatory agents such as5-aminosalicylate compounds and immune modulators have been considered as potential chemopreventive agents.Colonoscopic surveillance is widely accepted as being effective in reducing the risk of IBD-associated CRC,although no clear evidence has confirmed that surveillance colonoscopy prolongs survival in patients with extensive colitis.The traditional recommendation has been quadrantic random biopsies throughout the entire colon;however,several guidelines now have endorsed chromoendoscopy with a target biopsy because of increasing diagnostic yields and reduced workloads for endoscopists and pathologists.New technologies such as narrow band imaging,confocal endomicroscopy,and autofluorescence imaging have not yet been confirmed as surveillance strategies in IBD. | Eun Ran Kim Dong Kyung Chang | 2014 | World Journal of Gastroenterology2014,20,29: | 15 |
| 7 | The GW2-WG1-OsbZIP47 pathway controls grain size and weight in rice显示文摘Regulation of seed size is a key strategy for improving crop yield and is also a basic biological question.However,the molecular mechanisms by which plants determine their seed size remain elusive.Here,we report that the GW2-WG1-OsbZIP47 regulatory module controls grain width and weight in rice.WG1,which encodes a glutaredoxin protein,promotes grain growth by increasing cell proliferation.Interestingly,WG1 interacts with the transcription factor OsbZIP47 and represses its transcriptional activity by associating with the transcriptional co-repressor ASP1,indicating that WG1 may act as an adaptor protein to recruit the transcriptional co-repressor.In contrary,OsbZIP47 restricts grain growth by decreasing cell proliferation.Further studies reveal that the E3 ubiquitin ligase GW2 ubiquitinates WG1 and targets it for degradation.Genetic analyses confirm that GW2,WG1,and OsbZIP47 function in a comm on pathway to control grain growth.Taken together,ourfindi ngs reveal a genetic and molecular framework for the control of grain size and weight by the GW2-WG1-OsbZIP47 regulatory module,providing new targets for improving seed size and weight in crops. | Jianqin Hao Dekai Wang Yingbao Wu Ke Huang Penggen Duan Na Li Ran Xu Dali Zeng Guojun Dong Baolan Zhang Limin Zhang Dirk Inze Qian Qian Yunhai Li | 2021 | Molecular Plant2021,14,8: | 14 |
| 8 | Integrated metabolomic and transcriptomic analyses revealed the distribution of saponins in Panax notoginseng显示文摘Panax notoginseng is famous for its important therapeutic effects. Saponins are bioactive compounds found in different parts and developmental stages of P. notoginseng plants. Thus, it is urgently to study saponins distribution in different parts and growth ages of P. notoginseng plants. In this study,potential biomarkers were found, and their chemical characteristic differences were revealed through metabolomic analysis. High-performance liquid chromatography data indicated the higher content of saponins(i.e., Rg1, Re, Rd, and Rb1) in the underground parts than that in the aerial parts. 20(S)-Protopanaxadiol saponins were mainly distributed in the aerial parts. Additionally, the total saponin content in the 3-year-old P. notoginseng plant(188.0 mg/g) was 1.4-fold higher than that in 2-year-old plant(130.5 mg/g). The transcriptomic analysis indicated the tissue-specific transcription expression of genes, namely, PnFPS, PnSS, PnSE1, PnSE2, and PnDS, which encoded critical synthases in saponin biosyntheses. These genes showed similar expression patterns among the parts of P. notoginseng plants.The expression levels of these genes in the flowers and leaves were 5.2 fold higher than that in the roots and fibrils. These results suggested that saponins might be actively synthesized in the aerial parts and transformed to the underground parts. This study provides insights into the chemical and genetic characteristics of P. notoginseng to facilitate the synthesis of its secondary metabolites and a scientific basis for appropriate collection and rational use of this plant. | Guangfei Wei Linlin Dong Juan Yang Lianjuan Zhang Jiang Xu Feng Yang Ruiyang Cheng Ran Xu Shilin Chen | 2018 | Acta Pharmaceutica Sinica B2018,8,3: | 13 |

| 10 | Thiopurine S-methyltransferase polymorphisms and thiopurine toxicity in treatment of inflammatory bowel disease显示文摘AIM: To evaluate the relationship between thiopu- rine S-methyltransferase (TPMT) polymorphisms and thiopurine-induced adverse drug reactions (ADRs) in inflammatory bowel disease (IBD). METHODS: Eligible articles that compared the frequency of TPMT polymorphisms among thiopurine-tolerant and-intolerant adult IBD patients were included. Statistical analysis was performed with Review Manager 5.0. Sub-analysis/sensitivity analysis was also performed. RESULTS: Nine studies that investigated a total of 1309 participants met our inclusion criteria. The inci- dence of TPMT gene mutation was increased 2.93-fold (95% CI: 1.68-5.09, P = 0.0001) and 5.93-fold (95% CI: 2.96-11.88, P < 0.00001), respectively, in IBD patients with thiopurine-induced overall ADRs and bone marrow toxicity (BMT), compared with controls. The OR for TPMT gene mutation in IBD patients withthiopurine-induced hepatotoxicity and pancreatitis was 1.51 (95% CI: 0.54-4.19, P = 0.43) and 1.02 (95% CI: 0.26-3.99, P = 0.98) vs controls, respectively. CONCLUSION: This meta-analysis suggests that the TPMT polymorphisms are associated with thiopurine-induced overall ADRs and BMT, but not with hepatotoxicity and pancreatitis. | Xian-Wen Dong Qing Zheng Ming-Ming Zhu Jing-Lu Tong Zhi-Hua Ran | 2010 | World Journal of Gastroenterology2010,16,25: | 10 |
| 11 | Dissecting and Enhancing the Contributions of High-Molecular-Weight Glutenin Subunits to Dough Functionality and Bread Quality显示文摘Dear Editor, Seed storage proteins (SSPs) are frequently important determinants of crop quality traits (Shewry and Casey,1999).Dissecting and enhancing the genetic contributions of individual SSPs to their target traits are essential for effectively improving crop quality attributes.However,such a task is often difficult to accomplish,because SSPs are frequently expressed from multigene families and exhibit strong allelic variation.Consequently,detailed knowledge of the function of individual SSPs in crop quality trait is still limited.This scenario is well illustrated by high-molecular-weight glutenin subunits (HMWGSs),a complex family of SSPs that are involved in wheat enduse quality through affecting dough functionality (Békés,2012;Rasheed et al.,2014). | Yiwen Li Xuefi An Ran Yang Xiaomin Guo Guidong Yue Renchun Fan Bin Li Zhensheng Li Kunpu Zhang Zhenying Dong Luyan Zhang Jiankang Wang Xu Jia Hong-Qing Ling Aimin Zhang Xiangqi Zhang Daowen Wang | 2015 | Molecular Plant2015,8,2: | 9 |
| 12 | Potential targets for protecting against hippocampal cell apoptosis after transient cerebral ischemiareperfusion injury in aged rats显示文摘Mitochondria play an important role in neuronal apoptosis caused by cerebral ischemia, and the role is mediated by the expression of mitochondrial proteins. This study investigated the involvement of mitochondrial proteins in hippocampal cell apoptosis after transient cerebral ischemia-reperfusion injury in aged rats using a comparative proteomics strategy. Our experimental results show that the aged rat brain is sensitive to ischemia-reperfusion injury and that transient ischemia led to cell apoptosis in the hippocampus and changes in memory and cognition of aged rats. Differential proteomics analysis suggested that this phenomenon may be mediated by mitochondrial proteins associated with energy metabolism and apoptosis in aged rats. This study provides potential drug targets for the treatment of transient cerebral ischemia-reperfusion injury. | Xiangyu Ji Li'na Zhang Ran Liu Yingzhi Liu Jianfang Song He Dong Yanfang Jia Zangong Zhou | 2014 | Neural Regeneration Research2014,9,11: | 9 |
| 13 | Fully distributed time-varying formation tracking control for multiple quadrotor vehicles via finite-time convergent extended state observer显示文摘This paper investigates a time-varying anti-disturbance formation problem for a group of quadrotor aircrafts with time-varying uncertainties and a directed interaction topology.A novel Finite-Time Convergent Extended State Observer(FTCESO)based fully-distributed formation control scheme is proposed to enhance the disturbance rejection and the formation tracking performances for networked quadrotors.By adopting the hierarchical control strategy,the multiquadrotor system is separated into two subsystems:the outer-loop cooperative subsystem and the inner-loop attitude subsystem.In the outer-loop subsystem,with the estimation of disturbing forces and uncertain dynamics from FTCESOs,an adaptive consensus theory based cooperative controller is exploited to ensure the multiple quadrotors form and maintain a time-varying pattern relying only on the positions of the neighboring aircrafts.In the inner-loop subsystem,the desired attitude generated by the cooperative control law is stably tracked under a FTCESO-based attitude controller in a finite time.Based on a detailed algorithm to specify the cooperative control protocol,the feasibility condition to achieve the time-varying anti-disturbance formation tracking is derived and the rigorous analysis of the whole closed-loop multi-quadrotor system is given.Some numerical examples are conducted to intuitively demonstrate the effectiveness and the improvements of the proposed control framework. | Wenqiang ZHANG Chaoyang DONG Maopeng RAN Yang LIU | 2020 | Chinese Journal of Aeronautics2020,33,11: | 8 |

| 17 | Mechanical properties and microstructure of 3D-printed high Co–Ni secondary hardening steel fabricated by laser melting deposition显示文摘The mechanical properties and microstructure of the 3D-printed high Co–Ni secondary hardening steel fabricated by the laser melting deposition technique was investigated using a material testing machine and electron microscopy. A microstructure investigation revealed that the samples consist of martensite laths, fine dispersed precipitates, and reverted austenite films at the martensite lath boundaries. The precipitates are enriched with Co and Mo. Because the sample tempered at 486°C has smaller precipitates and a higher number of precipitates per unit area, it exhibits better mechanical properties than the sample tempered at 498°C. Although the 3D-printed samples have the same phase constituents as Aer Met 100 steel, the mechanical properties are slightly worse than those of the commercial wrought Aer Met 100 steel because of the presence of voids. | Hui-ping Duan Xiao Liu Xian-zhe Ran Jia Li Dong Liu | 2017 | International Journal of Minerals,Metallurgy and Materials2017,24,9: | 5 |
| 18 | Chromosome-level genome assembly,annotation and evolutionary analysis of the ornamental plant Asparagus setaceus显示文摘Asparagus setaceus is a popular ornamental plant cultivated in tropical and subtropical regions globally.Here,we constructed a chromosome-scale reference genome of A.setaceus to facilitate the investigation of its genome characteristics and evolution.Using a combination of Nanopore long reads,Illumina short reads,10×Genomics linked reads,and Hi-C data,we generated a high-quality genome assembly of A.setaceus covering 710.15 Mb,accounting for 98.63%of the estimated genome size.A total of 96.85%of the sequences were anchored to ten superscaffolds corresponding to the ten chromosomes.The genome of A.setaceus was predicted to contain 28,410 genes,25,649(90.28%)of which were functionally annotated.A total of 65.59%of the genome was occupied by repetitive sequences,among which long terminal repeats were predominant(42.51%of the whole genome).Evolutionary analysis revealed an estimated divergence time of A.setaceus from its close relative A.officinalis of~9.66 million years ago,and A.setaceus underwent two rounds of whole-genome duplication.In addition,762 specific gene families,96 positively selected genes,and 76 resistance(R)genes were detected and functionally predicted in A.setaceus.These findings provide new knowledge about the characteristics and evolution of the A.setaceus genome,and will facilitate comparative genetic and genomic research on the genus Asparagus. | Shu-Fen Li Jin Wang Ran Dong Hong-Wei Zhu Li-Na Lan Yu-Lan Zhang Ning Li Chuan-Liang Deng Wu-Jun Gao | 2020 | Horticulture Research2020,7,1: | 4 |
