| 2 | Integrative analysis of DNA methylation and gene expression identified cervical cancer-specific diagnostic biomarkers显示文摘Cervical cancer is the leading cause of death among women with cancer worldwide.Here,we performed an integrative analysis of Illumina HumanMethylation450K and RNA-seq data from TCGA to identify cervical cancer-specific DNA methylation markers.We first identified differentially methylated and expressed genes and examined the correlation between DNA methylation and gene expression.The DNA methylation profiles of 12 types of cancers,including cervical cancer,were used to generate a candidate set,and machine-learning techniques were adopted to define the final cervical cancer-specific markers in the candidate set.Then,we assessed the protein levels of marker genes by immunohistochemistry by using tissue arrays containing 93 human cervical squamous cell carcinoma samples and cancer-adjacent normal tissues.Promoter methylation was negatively correlated with the local regulation of gene expression.In the distant regulation of gene expression,the methylation of hypermethylated genes was more likely to be negatively correlated with gene expression,while the methylation of hypomethylated genes was more likely to be positively correlated with gene expression.Moreover,we identified four cervical cancer-specific methylation markers,cg07211381(RAB3C),cg12205729(GABRA2),cg20708961(ZNF257),and cg26490054(SLC5A8),with 96.2%sensitivity and 95.2%specificity by using the tenfold cross-validation of TCGA data.The four markers could distinguish tumors from normal tissues with a 94.2,100,100,and 100%AUC in four independent validation sets from the GEO database.Overall,our study demonstrates the potential use of methylation markers in cervical cancer diagnosis and may boost the development of new epigenetic therapies. | Wanxue Xu Mengyao Xu Longlong Wang Wei Zhou Rong Xiang Yi Shi Yunshan Zhang Yongjun Piao | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 4 |
| 3 | Modification of Mn on corrosion and mechanical behavior of biodegradable Mg(88)Y4Zn2Li5 alloy with long-period stacking ordered structure显示文摘The biological corrosion behavior and mechanical properties of Mg(89-x)Y4 Zn2 Li5 Mnx(x=0,0.5,1,1.5 and2 at.%) alloy with long-period stacking ordered(LPSO) structure were investigated in this work.The magnesium matrix and the eutectic phase of Mg(88)Y4 Zn2 Li5 Mn1 alloy are effectively refined by the grain boundary segregation of Mn,and the average size of matrix and the eutectic phase decreased by 66%and 74%,respectively.The ultimate tensile strength(UTS) and elongation enhanced by 36% and 55%,respectively.The corrosion rates obtained by weight loss and hydrogen evolution of Mg(88)Y4 Zn2 Li5 Mn1 alloy were 79% and 84% lower than that of Mg(88)Y4 Zn2 Li5 alloy.Additionally,Mg(88)Y4 Zn2 Li5 Mn1 alloy also presents superior corrosion behavior in electrochemical test.It is verified that Mn plays a positive role in both corrosion and mechanical properties of the Mg(88)Y4 Zn2 Li5 Mn1 alloy,which provides a reference for further experimental work. | Jiaxin Zhang Jinshan Zhang Fuyin Han Wei Liu Longlong Zhang Rui Zhao Chunxiang Xu Jing Dou | 2020 | Journal of Materials Science & Technology2020，42，7： | 4 |
| 4 | Sonodynamic therapy with immune modulatable two-dimensional coordination nanosheets for enhanced anti-tumor immunotherapy显示文摘Ultrasound with deep penetration depth and high security could be adopted in sonodynamic therapy(SDT)by activating sonosensitizers to generate cytotoxic reactive oxygen species(ROS).Herein,two-dimensional(2D)coordination nanosheets composed of Zn^(2+)and Tetrakis(4-carboxyphenyl)porphyrin(TCPP)are fabricated.While exhibiting greatly enhanced ultrasoundtriggered ROS generation useful for noninvasive SDT,such Zn-TCPP 2D nanosheets show high loading capacity of oligodeoxynudeotides such as cytosine—phosphorothioate-guanine(CpG),which is a potent toll like receptor 9(TLR9)agonist useful in activating immune responses.Highly effective SD T of primary tumors could release tumor-associated antigens,which working together with Zn-TCPP/CpG adjuvant nanosheets could function like whole-tumor-cell vaccines and trigger tumor-specific immune responses.Interestingly,ultrasound itself could strengthen anti-tumor immune responses by improving the tumor-infiltration of T cells and limiting regulatory T cells in the tumor microenvironment.Thus,SDT using Zn-TCPP/CpG nanosheets after destruction of primary tumors could induce potent antitumor immune responses to inhibit distant abscopal tumors without direct SD T treatment.Moreover,SDT with Zn-TCPP/CpG could trigger strong immunological memory effects to inhibit cancer recurrence after elimination of primary tumors.Therefore,the 2D coordination nanosheet may be a promising platform to deliver potent SDT-triggered immunotherapy for highly effective cancer treatment. | Wenjun Zhu Qian Chen Qiutong Jin Yu Chao Lele Sun Xiao Han Jun Xu Longlong Tian Jinglei Zhang Teng Liu Zhuang Liu | 2021 | Nano Research2021，14，1： | 3 |

| 6 | Rotational Friction Damper’s Performance for Controlling Seismic Response of High Speed Railway Bridge-Track System显示文摘CRTS-II slab ballastless track on bridge is a unique system in China high speed railway.The application of longitudinal continuous track system has obviously changed dynamic characteristics of bridge structure.The bridge system and CRTS-II track system form a complex nonlinear system.To investigate the seismic response of high speed railway(HSR)simply supported bridge-track system,nonlinear models of three-span simply supported bridge with piers of different height and CRTS-II slab ballastless track system are established.By seismic analysis,it is found that shear alveolar in CRTS-II track system is more prone to be damaged than bridge components,such as piers,girders and bearings.The result shows that the inconsistent displacement of bridge girders is the main cause of the CRTS-II track system’s damage.Then the rotational friction damper(RFD)is adopted,which utilizes the device’s rotation and friction to dissipate seismic energy.The hysteretic behavior of RFD is studied by numerical and experimental methods.Results prove that RFD can provide good hysteretic energy dissipation ability with stable performance.Furthermore,the analysis of RFD’s influence on seismic response of HSR bridge-track system shows that RFD with larger sliding force is more effective in controlling excessive inconsistent displacement where RFD is installed,though response of other bridge spans could slightly deteriorated. | Wei Guo Chen Zeng Hongye Gou Yao Hu Hengchao Xu Longlong Guo | 2019 | Computer Modeling in Engineering & Sciences2019，，9： | 3 |

| 13 | In situ synthesis of biomass-derived Ni/C catalyst by self-reduction for the hydrogenation of levulinic acid to γ-valerolactone显示文摘Herein,we reported in situ synthesis of biomass-derived Ni/C catalyst by self-reduction with pomelo peel.Compared with the conventional method, which includes carbonization, activation, impregnation and reduction, the entire preparation process was simplified to two steps, which was more straightforward. This synthesis method was green as Ni/C can be prepared without any additional chemical and the self-reduction process was realized in N2, which can avoid using H2 thus averting some problems such as storage, transportation and safety of H2. Meanwhile, the size and dispersion of Ni particles can be controlled by changing carbonization temperature.The synthesis mechanism of Ni/C catalyst with selfreduction was investigated, which was mainly attributed to the carbon and reducing gas produced during the carbonization process.For the catalytic performance of GVL synthesis, a high yield (94.5%) can be obtained and it exhibited good stability up to 5 cycles without obvious loss of catalytic activity. | Shuqi Fang Zhibing Cui Yuting Zhu Chenguang Wang Jing Bai Xinghua Zhang Ying Xu Qiying Liu Lungang Chen Qi Zhang Longlong Ma | 2019 | Journal of Energy Chemistry2019，28，10： | 1 |

| 15 | Seryl tRNA synthetase cooperates with POT1 to regulate telomere length and cellular senescence显示文摘Deregulated telomere length is a causative factor in many physiological and pathological processes,including aging and cancer.Many studies focusing on telomeres have revealed important roles for cooperation between the Shelterin protein complex and telomerase in maintaining telomere length.However,it remains largely unknown whether and how aging-related stresses,such as deregulated protein homeostasis,impact telomere length.Here,we explored the possible roles of aminoacyl tRNA synthetases(AARSs),key enzymes catalyzing the first reactions in protein synthesis,in regulating telomere length and aging.We selected seryl tRNA synthetase(SerRS)since our previous studies discovered expanded functions of SerRS in the nucleus in addition to its canonical cytoplasmic role in protein synthesis.In this study,we revealed that overexpression of SerRS promoted cellular senescence and inhibited the growth of cervical tumor xenografts in mice by triggering the senescence of tumor cells.In the nucleus,SerRS directly bound to telomeric DNA repeats and tethered more POT1 proteins to telomeres through a direct interaction between the UNE-S domain of SerRS and the OB1 domain of POT1.We further demonstrated that SerRS-induced enrichment of POT1 prevented the recruitment of telomerase to telomeres,resulting in progressive telomere shortening.Our data suggested a possible molecular link between protein synthesis and telomere length control,the deregulation of which may be associated with aging and cancer. | Yingxi Li Xiyang Li Mei Cao Yuke Jiang Jie Yan Ze Liu Rongcun Yang Xu Chen Peiqing Sun Rong Xiang Longlong Wang Yi Shi | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 1 |

| 17 | Hydrogenolysis of organosolv hydrolyzed lignin over high-dispersion Ni/Al-SBA-15 catalysts for phenolic monomers显示文摘Efficiency and recycling of catalysts are important for the lignin hydrogenolysis to obtain phenolic monomers.In this work,a series of highdispersion Ni/AlSBA15 catalysts were prepared by a direct and effective preparation method,and then used in the hydrogenolysis of diphenyl ether(DE)and organosolv hydrolyzed lignin(OHL)for phenolic monomers.The universality of asmade catalysts in different solvents and cyclic performance were investigated.Results showed that the addition of ethylene glycol(EG)during the loading process of Ni promoted the dispersion of metal efficiently.High dispersion of Ni species could highly enhance the conversion of DE and the OHL which Ni/AlSBA15(1EG)exhibited the excellent catalytic performance.Decalin was found to be most effective solvent on the conversion of DE(99.16%).84.77%liquefaction ratio and 21.36%monomer yield were achieved,and no obvious char was observed after the depolymerization of OHL in ethanol solvent at 280℃for 4 h over the Ni/AlSBA15(1EG)catalyst. | Ying Xu Pengru Chen Wei Lv Chenguang Wang Longlong Ma Qi Zhang | 2021 | Chinese Journal of Chemical Engineering2021，34，4： | 1 |
| 18 | Development of sensor system for real-time measurement of droplet deposition of agricultural sprayers显示文摘During the chemical application process,droplet deposition on a target is an important reference indicator for evaluating the spraying technique and its performance.In order to quickly obtain deposition results in the field,this study proposed a novel system based on surface humidity sensors.The basic principle is to convert the measured physical quantity change into a capacitance change,thereby realizing the physical quantity to electrical signal conversion.An Android application for mobile terminal and the corresponding coordinator were developed,which allowed operators to control multiple sensors simultaneously through the Bluetooth.The soluble tracer detected by spectrophotometer was used to calibrate the system.The obtained results indicated a good correlation between deposition volume and voltage increment output from the newly developed system(R2 of the six nozzles with Dv0.5 ranging from 107.28μm to 396.20μm were 0.8674-0.9729),and a power regression model based on the least squares technique(R2=0.8022)was developed.In the field test,the system exhibited an optimal performance in predicting the deposition volume.Compared with the conventional method of measuring tracer concentration,the deviation was less than 10%.In addition,the system exhibited good fitting curve of the deposition distribution with droplet number results measured by the water sensitive paper method. | Longlong Li Ruirui Zhang Liping Chen Tongchuan Yi Gang Xu Daxuan Xue Qing Tang Linhuan Zhang Andrew John Hewitt Yining An | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 1 |
| 19 | Hydrocarbon Generation Characteristics of Source Rocks from Different Saline Environments in the Dongpu Depression,Bohai Bay Basin,China显示文摘The Dongpu Depression is a secondary salt-bearing tectonic unit in the Bohai Bay Basin,eastern China.The depositional environment of this depression regarding its Paleogene strata is clearly different in plane,including the saltwater environment(SE)in the north,the freshwater environment(FE)in the south and the brackish water environment(BE)in the middle.The result of oil and gas exploration in the Dongpu Depression shows that more than 90%of the proven oil reserves are distributed in the northern saltwater environment.Previous studies indicate that the organic geochemistry characteristics and the hydrocarbon generation capacity of the source rocks are very clearly diverse under different environments,which results in the significant differences in the proved reserves between the north and the south.In order to further explore the differences in the hydrocarbon generation capacity of the source rocks under distinct depositional environments and the mechanism of their occurrence,three samples from different depositional environments(W18-5 for SE,H7-18 for BE,CH9 for FE)were used for confined gold tube pyrolysis experiments.The results show that the CH4 yields of W18-5,H7-18 and CH9 increase with increasing temperature,the maximum yields being 405.62 mg/g TOC,388.56 mg/g TOC and 367.89 mg/g TOC,respectively.The liquid hydrocarbon yields of W18-5,H7-18 and CH9 firstly increase with increasing temperature and then decrease after the critical temperatures.The maximum yields of C6-14 are 149.54 mg/g TOC,140.18 mg/g TOC and 116.94 mg/g TOC,the maximum yields of C14+being 852.4 mg/g TOC,652.6 mg/g TOC and 596.41 mg/g TOC,respectively for W18-5,H7-18 and CH9.To summarize,the order of hydrocarbon potential from high to low is W18-5,H7-18 and CH9.On this basis,through analyzing the influencing factors of hydrocarbon differences,this paper reveals that the saltwater environment is characterized by 4 factors:higher salinity,halophilic algae,high paleo-productivity and a strongly reducing environment,which are beneficial to the enrichment of organic matter and lead to the formation of high levels of sapropelite and exinite.According to the variation of oil and gas components in the pyrolysis experiments,the hydrocarbon generation process is divided into three stages:kerogen cracking,oil cracking and C2-5 cracking.Combined with hydrocarbon generation characteristics and stages,the evolutionary model of hydrocarbon generation for source rocks under different environments is established. | LI Wendu ZHANG Pengyuan JIANG Fujie ZHANG Yunxian HUANG Renda XU Tianwu ZHOU Yongshui LI Longlong JIANG Wenli | 2021 | Acta Geologica Sinica(English Edition)2021，95，4： | 0 |
| 20 | Surface protection method for the magnetic core using covalent organic framework shells and its application in As(Ⅲ)depth removal from acid wastewater显示文摘Fe_(3)O_(4)-based materials are widely used for magnetic separation from wastewater.However,they often suffer from Fe-leaching behavior under acidic conditions,decreasing their ac-tivity and limiting sustainable practical applications.In this study,covalent organic frame-works(COFs)were used as the shell to protect the Fe_(3)O_(4) core,and the Fe_(3)O_(4)@COF core-shell composites were synthesized for As(Ⅲ)removal from acid wastewater.The imine-linked COFs can in situ grow on the surface of the Fe_(3)O_(4) core layer by layer with[COFs/Fe_(3)O_(4)]mol ratio of up to 2∶1.The Fe-leaching behavior was weakened over a wide pH range of 1-13.Moreover,such composites keep their magnetic characteristic,making them favorable for nanomaterial separation.As(Ⅲ)batch adsorption experiments results indicated that,when COFs are used as the shell for the Fe_(3)O_(4) core,a balance between As(Ⅲ)removal efficiencies and the thickness of the COF shell exists.Higher As(Ⅲ)removal efficiencies are obtained when the[COFs/Fe_(3)O_(4)]mol ratios were<1.5∶1,but thicker COF shells were not beneficial for As(Ⅲ)removal.Such composites also exhibited better As(Ⅲ)removal performances in the pH range of 1-7.Over a wide pH range,the zeta potential of Fe_(3)O_(4)@COF core-shell compos-ites becomes more positive,which benefits the capture of negative arsenic ions.In addition,thinner surface COFs were favorable for mass transfer and facilitating the reaction of Fe and As elements.Our study highlights the promise of using COFs in nanomaterial surface protection and achieving As(Ⅲ)depth removal under acidic conditions. | Wenjun Huang Haomiao Xu Xiaoshuang Liu Longlong Wang Shutang Li Leipeng Ji Zan Qu Naiqiang Yan | 2022 | Journal of Environmental Sciences2022，34，5： | 0 |
