| 1 | Characterization of dissolved organic matter fractions from Lake Hongfeng, Southwestern China Plateau显示文摘With XAD-series and ion exchange resins, dissolved organic matter (DOM) from Lake Hongfeng in Southwestern China Plateau was isolated into 6 fractions, i.e., humic acid (HA), fulvic acid (FA), hydrophobic neutrals (HON), hydrophilic acids (HIA), hydrophilic bases (HIB) and hydrophilic neutrals (HIN). Those fractions were characterized by high performance size exclusion chromatography, fluorescence spectroscopy and UV absorbance. Among the 6 fractions, FA was predominant and accounted for 51% of the total DOM. The weight-average (Mw) and number-averaged (Mn) molecular weight of these fractions ranged from 1688 to 2355 Da and from 1338 to 1928 Da, respectively. A strong correlation was observed between specific UV absorbance at 280 nm, E2/E3 (absorbance at 250 nm to 365 nm), and the molecular weight for DOM fractions. UV-Vis fulvic-like fluorescence peaks were found in all fractions. Protein-like fluorescence peaks existed in HON may indicate that microbial activity was severely in Lake Hongfeng. There was a significant relationship between fluorescence intensities and specific UV absorbance at 254 nm for those DOM fractions, suggesting their similar luminescence characteristics. The values of fluorescence index (f450/500) indicated that hydrophobic fractions may derive from terrestrial sources, and the hydrophilic fractions from microbial and terrestrial origins. Those results suggest that there were inter-relationships between molecular weight, fluorescence and absorbance characteristics, and also subtle consistencies between the hydrophilic and hydrophobic properties and the sources for these 6 fractions from Lake Hongfeng. | WANG Liying WU Fengchang ZHANG Runyu LI Wen LIAO Haiqing | 2009 | Journal of Environmental Sciences2009，21，5： | 61 |
| 2 | Upregulation of Chemokine CXCL12 in the Dorsal Root Ganglia and Spinal Cord Contributes to the Development and Maintenance of Neuropathic Pain Following Spared Nerve Injury in Rats显示文摘Emerging evidence indicates that CXCL12/CXCR4 signaling is involved in chronic pain. However, few studies have systemically assessed its role in direct nerve injury-induced neuropathic pain and the underlying mechanism. Here, we determined that spared nerve injury(SNI)increased the expression of CXCL12 and its cognate receptor CXCR4 in lumbar 5 dorsal root ganglia(DRG)neurons and satellite glial cells. SNI also induced longlasting upregulation of CXCL12 and CXCR4 in the ipsilateral L4–5 spinal cord dorsal horn, characterized by CXCL12 expression in neurons and microglia, and CXCR4 expression in neurons and astrocytes. Moreover, SNIinduced a sustained increase in TNF-a expression in the DRG and spinal cord. Intraperitoneal injection(i.p.) of the TNF-a synthesis inhibitor thalidomide reduced the SNI-induced mechanical hypersensitivity and inhibited the expression of CXCL12 in the DRG and spinal cord.Intrathecal injection(i.t.) of the CXCR4 antagonist AMD3100, both 30 min before and 7 days after SNI,reduced the behavioral signs of allodynia. Rats given an i.t.or i.p. bolus of AMD3100 on day 8 of SNI exhibited attenuated abnormal pain behaviors. The neuropathic pain established following SNI was also impaired by i.t. administration of a CXCL12-neutralizing antibody. Moreover,repetitive i.t. AMD3100 administration prevented the activation of ERK in the spinal cord. The mechanical hypersensitivity induced in na?¨ve rats by i.t. CXCL12 was alleviated by pretreatment with the MEK inhibitor PD98059. Collectively, our results revealed that TNF-a might mediate the upregulation of CXCL12 in the DRG and spinal cord following SNI, and that CXCL12/CXCR4 signaling via ERK activation contributes to the development and maintenance of neuropathic pain. | Liying Bai Xinru Wang Zhisong Li Cunlong Kong Yonghui Zhao Jun-Liang Qian Quancheng Kan Wei Zhang Ji-Tian Xu | 2016 | Neuroscience Bulletin2016，32，1： | 20 |

| 4 | Binding characteristics of perylene, phenanthrene and anthracene to different DOM fractions from lake water显示文摘Six hydrophobic and hydrophilic fractions were isolated using XAD-8 and XAD-4 resins, and were extensively characterized. Partition coefficients of perylene, phenanthrene and anthracene binding to the six fractions were determined by fluorescence quenching titration. The Kdoc values obtained for the polycyclic aromatic hydrocarbons (PAHs) binding to the hydrophobic fractions were larger than those to the hydrophilic fractions. Nonlinear Stern-Volmer plots were observed when binding phenanthrene and anthracene to some hydrophilic fraction samples, suggesting saturation of polar interaction binding sites. A significant correlation of logKdoc values with molecular weights and molar absorptivities at 280 nm was observed, while atomic ratio of C/H was found to be a poor indicator for aromaticity. Other structural descriptors such as paraffinic carbon and polarity influenced the DOM-fraction ability to bind PAHs. Different interaction mechanisms underlying binding of the different fractions to the PAHs were also discussed. | MEI Yi WU Fengchang WANG Liying BAI Yingchen LI Wen LIAO Haiqing | 2009 | Journal of Environmental Sciences2009，21，4： | 16 |

| 7 | Relationship between fluorescence characteristics and molecular weight distribution of natural dissolved organic matter in Lake Hongfeng and Lake Baihua,China显示文摘Dissolved organic matter (DOM) is one of the most interesting and difficult problems in recent years due to its important functions in the ecological and environmental system and the complexity of its chemical composition and structure. It is well ac- cepted that fluorescence characteristics and mo- lecular weight distribution are two important pa- rameters in the DOM characterization. However, the relationship between them is still unknown. In this study, fluorescence and molecular weight distribution of DOM in Lake Hongfeng, Lake Baihua and their rivers, and their relationship were investigated using the combination of fluorescence spectroscopy and high-performance size exclusion chromatography (HPSEC) with on-line UV absorbance and fluores- cence detectors. The results show that there were two obvious humic-like fluorescence peaks (Peaks A and B) in DOM from lake water. But there was an- other obvious protein-like fluorescence peak (Peak C) in DOM from river water. The humic-like fluorescence material consisted of DOM fraction with smaller mo- lecular weight, ranging from 1.0 to 3.0 kDa, while the protein-like fluorescence material mainly consisted of DOM fraction with MW larger than 2.0 kDa. The cal- culation of MW using HPSEC was related to the UV absorbance wavelength chosen. | YUE Lanxiu WU Fengchang LiU Congqiang LI Wen FU Pingqing BAI Yingchen WANG Liying YIN Zuoying Lü Zhicheng | 2006 | Chinese Science Bulletin2006，51，1： | 9 |
| 8 | Efficient degradation of chlorobenzene in a non-thermal plasma catalytic reactor supported on CeO_2/HZSM-5 catalysts显示文摘Chlorobenzene removal was investigated in a non-thermal plasma reactor using CeO_2/HZSM-5catalysts.The performance of catalysts was evaluated in terms of removal and energy efficiency.The decomposition products of chlorobenzene were analyzed.The results show that CeO_2/HZSM-5 exhibited a good catalytic activity,which resulted in enhancements of chlorobenzene removal,energy efficiency,and the formation of lower amounts of by-products.With regards to CO_2 selectivity,the presence of catalysts favors the oxidation of by-products,leading to a higher CO_2 selectivity.With respect to ozone,which is considered as an unavoidable by-product in air plasma reactors,a noticeable decrease in its concentration was observed in the presence of catalysts.Furthermore,the stability of the catalyst was investigated by analyzing the evolution of conversion in time.The experiment results indicated that CeO_2/HZSM-5 catalysts have excellent stability:chlorobenzene conversion only decreased from 78%to 60%after 75 hr,which means that the CeO_2/HZSM-5 suffered a slight deactivation.Some organic compounds and chlorinated intermediates were adsorbed or deposited on the catalysts surface as shown by the results of Fourier Transform Infrared(FT-IR) spectroscopy,scanning electron microscope(SEM) and energy dispersive X-ray spectroscopy(EDS) analyses of the catalyst before and after the reaction,revealing the cause of catalyst deactivation. | Liying Jiang Guofeng Nie Runye Zhu Jiade Wang Jianmeng Chen Yubo Mao Zhuowei Cheng Willam A.Anderson | 2017 | Journal of Environmental Sciences2017，29，5： | 8 |
| 9 | Salivary mycobiome dysbiosis and its potential impact on bacteriome shifts and host immunity in oral lichen planus显示文摘The biodiversity of the mycobiome,an important component of the oral microbial community,and the roles of fungal–bacterial and fungal–immune system interactions in the pathogenesis of oral lichen planus (OLP) remain largely uncharacterized.In this study,we sequenced the salivary mycobiome and bacteriome associated with OLP.First,we described the dysbiosis of the microbiome in OLP patients,which exhibits lower levels of fungi and higher levels of bacteria.Significantly higher abundances of the fungi Candida and Aspergillus in patients with reticular OLP and of Alternaria and Sclerotiniaceae_unidentified in patients with erosive OLP were observed compared to the healthy controls.Aspergillus was identified as an “OLP-associated” fungus because of its detection at a higher frequency than in the healthy controls.Second,the co-occurrence patterns of the salivary mycobiome–bacteriome demonstrated negative associations between specific fungal and bacterial taxa identified in the healthy controls,which diminished in the reticular OLP group and even became positive in the erosive OLP group.Moreover,the oral cavities of OLP patients were colonized by dysbiotic oral flora with lower ecological network complexity and decreased fungal–Firmicutes and increased fungal–Bacteroidetes sub-networks.Third,several keystone fungal genera (Bovista,Erysiphe,Psathyrella,etc.) demonstrated significant correlations with clinical scores and IL-17 levels.Thus,we established that fungal dysbiosis is associated with the aggravation of OLP.Fungal dysbiosis could alter the salivary bacteriome or may reflect a direct effect of host immunity,which participates in OLP pathogenesis. | Yan Li Kun Wang Bo Zhang Qichao Tu Yufei Yao Bomiao Cui Biao Ren Jinzhi He Xin Shen Joy D.Van Nostrand Jizhong Zhou Wenyuan Shi Liying Xiao Changqing Lu Xuedong Zhou | 2019 | International Journal of Oral Science2019，11，3： | 8 |
| 10 | Phosphorus speciation in the sediment profile of Lake Erhai, southwestern China: Fractionation and ^(31)P NMR显示文摘The distribution characteristics of phosphorus(P) forms in the sediment profile of Lake Erhai,in southwestern China has been investigated by sequential extraction and 31P nuclear magnetic resonance spectroscopy(NMR) of NaOH extracts to understand P dynamics and its potential contribution to lake eutrophication.Contents of P fractions varied in the order of NH4Cl extracted P(NH4ClP) < bicarbonate-dithionite extracted P(BD-P) < HCl-P,Residual-P < NaOH extracted P(NaOH-P).The highly available NH4Cl-P represented less than 1% of total P(TP).BD-P and NaOH extracted reactive P(NaOH-rP) averaged 39%,while the ratio of Fe/P was higher than 15,indicating low P release from the sediments under permanent oxic condition.The less bio-available HCl-P,NaOH extracted nonreactive P(NaOH-nrP) and residual-P contributed 61% of TP.Regression analysis revealed that BD-P,NaOH-rP and HCl-P were positively correlated with the contents of Fe and Mn,Al and Fe,and Ca,respectively.The investigation of P compound groups in NaOH extracts by 31 P NMR showed that ortho-P and monoester-P were the largest two constituents of the P pool,followed by diester-P,phosphonate and pyro-P.A comparison of vertical variations of P groups in the sediment profile suggested that these compounds were involved in the P recycling to different extents in Lake Erhai.In particular,the lake exhibits high potential for labile P release from the surface sediments,which should be taken into consideration even after the outsourced P runoff ceased. | Runyu Zhang Liying Wang Fengchang Wu Baoan Song | 2013 | Journal of Environmental Sciences2013，25，6： | 7 |
| 11 | Simultaneous stabilization of a class of nonlinear descriptor systems via Hamiltonian function method显示文摘This paper studies simultaneous stabilization of a class of nonlinear descriptor systems via the Hamiltonian function method. Firstly, based on the Hamiltonian realization of the nonlinear descriptor systems and a suitable output feedback, two nonlinear descriptor systems are equivalently transformed into two nonlinear Hamiltonian differential-algebraic systems by a nonsingular transformation, and a sufficient condition for two closed-loop systems to be impulse-free is given. The two systems are then combined to generate an augmented dissipative Hamiltonian differential-algebraic system by using the system-augmentation technique, based on which a simultaneous stabilization controller and a robust simultaneous stabilization controller are designed for the two systems. Secondly, the case of more than two nonlinear descriptor systems is investigated, and two new results are proposed for the simultaneous stabilization and robust simultaneous stabilization, respectively. Finally, an illustrative example is studied by using the results proposed in this paper, and simulations show that the simultaneous stabilization controllers obtained in this paper work very well. | SUN LiYing WANG YuZhen | 2009 | Science in China(Series F)2009，52，11： | 7 |
| 12 | Preparation and characterization of a composite membrane based on the asphaltene component of coal显示文摘Asphaltene-ceramic composite membranes were fabricated from ceramic supports and an asphaltene component, which was obtained from the separation of coal to give a kind of new carbonaceous precursor material. Using SEM and thermogravimetric analysis to measure the microstructure and properties of the asphaltene component allowed the porosity, permeability, and retention ratios to be determined. The results show that the asphaltene component can be regarded as a good carbon membrane precursor material because of its high carbon content and strong bonding capacity. When ceramic supports are impregnated with asphaltene colloid the asphaltene easily combines with the support surface and forms a good carbonaceous film after carbonization. Little of the asphaltene component permeates into the internal pores of the ceramic support. Although the number of coats applied to the substrate had little affect on the porosity of the asphaltene-ceramic composite membranes the permeability varied depending upon the number of times the substrate was treated. The way bubbles escape from the film, and the phenomenon of coalescence, as affected by different film thicknesses also seem closely related to the number of coats. A composite membrane carbonized at a final temperature of 600 °C is relatively dense and the permeability of Fe(OH) 3 colloid through it is very low. A membrane fired at 800 °C is porous and its permeability and retention of Fe(OH) 3 colloid are 88 L/(m 2 h MPa) and 85.3%, respectively when the trans-membrane pressure is 0.22 MPa. | Zhang Liying Qin Zhihong Li Xinyan Chen Juan Liu Peng Wang Xiaoyan | 2011 | Mining Science and Technology2011，21，3： | 7 |
| 13 | Incidence and mortality of corpus uteri cancer in China,2008-2012显示文摘Objective: To analyze the incidence and mortality rates of corpus uteri cancer in China using 2008-2012 data from the National Central Cancer Registry(NCCR) of China.Methods: We analyzed 2008-2012 data from 135 cancer registries using NCCR screening methods and criteria.The Chinese standard population in 2000 and Segi’s world population were applied to determine age-standardized incidence and mortality rates. The annual percentage change(APC) in rate was calculated using the Joinpoint Regression Program.Results: The crude incidence of corpus uteri cancer was 9.58/100,000, making corpus uteri cancer the ninth most common malignancy in females. The crude mortality was 2.97/100,000, making corpus uteri cancer the 13 th leading cause of death from malignant tumors in females. The incidence was higher in urban than in rural areas, but the mortality was higher in rural than in urban areas. The crude incidence was higher in eastern areas than in middle and western areas, while the crude mortality was higher in middle areas than in eastern and western areas.During 2003-2012, the age-standardized incidence rate based on the Chinese standard population in 2000(ASIRC)with uterine cancer increased significantly by 3.0% annually, while the age-standardized mortality rate based on the Chinese standard population in 2000(ASMRC) decreased by 0.4% annually, but the decrease was not statistically significant. The APC in incidence rate in the age groups of 30-44 years was 4.2%, which was statistically significant;increases/decreases in other age groups were not statistically significant. From 2003 to 2004, the age groups of 60-74 years showed high incidence, while from 2005 to 2012, the age groups of 45-59 years had high incidence.Conclusions: The incidence and mortality rates of corpus uteri cancer in China from 2008 to 2012 were relatively low compared with other countries. However, the significant increase in incidence rates and marked decrease in patient age suggest the need to strengthen China’s efforts toward prevention and control of corpus uteri cancer. | Yunfeng Xi Wenrui Wang Wenjie Chen Ke Han Liying Qiao Wanqing Chen | 2019 | Chinese Journal of Cancer Research2019，31，3： | 7 |
| 14 | Mechanisms underlying legume-rhizobium symbioses显示文摘Legumes,unlike most land plants,can form symbiotic root nodules with nitrogen-fixing bacteria to secure nitrogen for growth.The formation of nitrogen-fixing nodules on legume roots requires the coordination of rhizobial infection at the root epidermis with cell division in the cortex.The nodules house the nitrogen-fixing rhizobia in organelle-like structures known as symbiosomes,which enable nitrogen fixation and facilitate the exchange of metabolites between the host and symbionts.In addition to this beneficial interaction,legumes are continuously exposed to would-be pathogenic microbes;therefore the ability to discriminate pathogens from symbionts is a major determinant of plant survival under natural conditions.Here,we summarize recent advances in the understanding of root nodule symbiosis signaling,transcriptional regulation,and regulation of plant immunity during legume-rhizobium symbiosis.In addition,we propose several important questions to be addressed and provide insights into the potential for engineering the capacity to fix nitrogen in legume and nonlegume plants. | Jun Yang Liying Lan Yue Jin Nan Yu Dong Wang Ertao Wang | 2022 | Journal of Integrative Plant Biology2022，64，2： | 6 |
| 15 | Development of the triazole-fused pyrimidine derivatives as highly potent and reversible inhibitors of histone lysine specific demethylase1(LSD1/KDM1A)显示文摘Histone lysine specific demethylase 1(LSD1) has been recognized as an important modulator in post-translational process in epigenetics. Dysregulation of LSD1 has been implicated in the development of various cancers. Herein, we report the discovery of the hit compound 8 a(IC50=3.93 μmol/L) and further medicinal chemistry efforts, leading to the generation of compound 15 u(IC50=49 nmol/L, and Ki= 16 nmol/L), which inhibited LSD1 reversibly and competitively with H3 K4 me2, and was selective to LSD1 over MAO-A/B. Docking studies were performed to rationalize the potency ofcompound 15 u. Compound 15 u also showed strong antiproliferative activity against four leukemia cell lines(OCL-AML3, K562, THP-1 and U937) as well as the lymphoma cell line Raji with the IC50 values of 1.79, 1.30, 0.45, 1.22 and 1.40 μmol/L, respectively. In THP-1 cell line, 15 u significantly inhibited colony formation and caused remarkable morphological changes. Compound 15 u induced expression of CD86 and CD11 b in THP-1 cells, confirming its cellular activity and ability of inducing differentiation.The findings further indicate that targeting LSD1 is a promising strategy for AML treatment, the triazolefused pyrimidine derivatives are new scaffolds for the development of LSD1/KDM1 A inhibitors. | Zhonghua Li Lina Ding Zhongrui Li Zhizheng Wang Fengzhi Suo Dandan Shen Taoqian Zhao Xudong Sun Junwei Wang Ying Liu Liying Ma Bing Zhao Pengfei Geng Bin Yu Yichao Zheng Hongmin Liu | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 6 |
| 16 | Genetic analysis and preimplantation genetic diagnosis of Chinese Marfan syndrome patients显示文摘Marfan syndrome (MFS)(OMIM 154700) is a relatively common autosomal dominant genetic disease that causes skeletal, ocular, and cardiovascular defects and was first described by a French pediatrician in 1896 (Bitterman and Sponseller, 2017). Its prevalence rate is 1/3000—1/5000, and more than 25% of cases are sporadic (Chiu et al., 2014). Studies have shown that about 90% of MFS is caused by variants in the fibrillin-1 gene (FBN1, OMIM 134797). FBN1, located on chromosome 15q21.1, encodes a macromolecular glycoprotein-fibrin 1, which aggregates to form microfibers in the extracellular matrix and distributes in various human connective tissues, such as periosteum, vessel wall, and crystal suspensor ligament. Variants in FNB1 have been reported in 65 exons, but the relationship between genotype and phenotype remains rather unclear (Sakai et al., 2016). Studies have also shown that patients with MFS and similar diseases may have variants in other related genes such as members of the transforming growth factor beta receptor (TGFBR) family (Mizuguchi et al., 2004;Sakai et al., 2006;Bolar et al., 2012;De Cario et al., 2018). For better prevention and treatment of MFS as well as for suspected MFS patients, there is a strong need for efficient genetic testing for early diagnosis and differential diagnoses of patients with related phenotypes (Aubart et al., 2018). | Meng Qin Xiaohui Zhu Zhe Zhang Xuemin Li Zhiqiang Yan Yuqian Wang Shuo Guan Yihua He Wenxin Zhang Liying Yan Jie Qiao Xu Zhi | 2019 | Journal of Genetics and Genomics2019，46，6： | 6 |

| 18 | The mechanism of side reaction induced capacity fading of Ni-rich cathode materials for lithium ion batteries显示文摘Ni-rich cathode materials show great potential of applying in high-energy lithium ion batteries,but their inferior cycling stability hinders this process.Study on the electrode/electrolyte interfacial reaction is indispensable to understand the capacity failure mechanism of Ni-rich cathode materials and further address this issue.This work demonstrates the domain size effects on interfacial side reactions firstly,and further analyzes the inherent mechanism of side reaction induced capacity decay through comparing the interfacial behaviors before and after MgO coating.It has been determined that LiF deposition caused thicker SEI films may not increase the surface film resistance,while HF erosion induced surface phase transition will increase the charge transfer resistance,and the later plays the dominant factor to declined capacity of Ni-rich cathode materials.This work suggests strategies to suppress the capacity decay of layered cathode materials and provides a guidance for the domain size control to match the various applications under different current rates. | Daozhong Hu Yuefeng Su Lai Chen Ning Li Liying Bao Yun Lu Qiyu Zhang Jing Wang Shi Chen Feng Wu | 2021 | Journal of Energy Chemistry2021，30，7： | 5 |

| 20 | Markov repairable systems with stochastic regimes switching显示文摘Compared with the classical Markov repairable system,the Markov repairable system with stochastic regimes switching introduced in the paper provides a more realistic description of the practical system.The system can be used to model the dynamics of a repairable system whose performance regimes switch according to the external conditions.For example,to satisfy the demand variation that is typical for the power and communication systems and reduce the cost,these systems usually adjust their operating regimes.The transition rate matrices under distinct operating regimes are assumed to be different and the sojourn times in distinct regimes are governed by a finite state Markov chain.By using the theory of Markov process,Ion channel theory,and Laplace transforms,the up time of the system are studied.A numerical example is given to illustrate the obtained results.The effect of sojourn times in distinct regimes on the availability and the up time are also discussed in the numerical example. | Liying Wang Lirong Cui Mingli Yu | 2011 | Journal of Systems Engineering and Electronics2011，22，5： | 5 |
