| 1 | Pitavastatin attenuates AGEs-induced mitophagy via inhibition of ROS generation in the mitochondria of cardiomyocytes显示文摘This study aimed to investigate whether pitavastatin protected against injury induced by advanced glycation end products products(AGEs) in neonatal rat cardiomyocytes,and to examine the underlying mechanisms.Cardiomyocytes of neonatal rats were incubated for 48 hours with AGEs(100 μg/mL),receptor for advanced glycation end products(RAGE),antibody(1 μg/mL) and pitavastatin(600 ng/mL).The levels of p62 and beclinl were determined by Western blotting.Mitochondrial membrane potential(△Ψm) and the generation of reactive oxygen species(ROS) were measured through the JC-1 and DCFH-DA.In the AGEs group,the expression of beclinl was remarkably increased compared to the control group,while the expression of p62 was significantly decreased.AGEs also markedly decreased △Ψm and significantly increased ROS compared with the control group.After treatment with RAGE antibody or pitavastatin,the level of beclinl was markedly decreased compared with the AGEs group,but the level of p62 was remarkably increased.In the AGEs + RAGE antibody group and AGEs+ pitavastatin group,△Ψm was significantly increased and ROS was remarkably decreased compared with the AGEs group.In conclusion,AGEs-RAGE may induce autophagy of cardiomyocytes by generation of ROS and pitavastatin could protect against AGEs-induced injury against cardiomyocytes. | Zhimin Zha Junhong Wang Shiling Li Yan Guo | 2018 | The Journal of Biomedical Research2018，32，4： | 6 |
| 2 | Counterintuitive Ballistic and Directional Liquid Transport on a Flexible Droplet Rectifier显示文摘Achieving the directional and long-range droplet transport on solid surfaces is widely preferred for many practical applications but has proven to be challenging.Particularly,directionality and transport distance of droplets on hydrophobic surfaces are mutually exclusive.Here,we report that drain fly,a ubiquitous insect maintaining nonwetting property even in very high humidity,develops a unique ballistic droplet transport mechanism to meet these demanding challenges.The drain fly serves as a flexible rectifier to allow for a directional and long-range propagation as well as self-removal of a droplet,thus suppressing unwanted liquid flooding.Further investigation reveals that this phenomenon is owing to the synergistic conjunction of multiscale roughness,structural periodicity,and flexibility,which rectifies the random and localized droplet nucleation(nanoscale and microscale)into a directed and global migration(millimeter-scale).The mechanism we have identified opens up a new approach toward the design of artificial rectifiers for broad applications. | Lei Wang Jing Li Bo Zhang Shile Feng Mei Zhang Dong Wu Yang Lu Ji Jung Kai Jing Liu Zuankai Wang Lei Jiang | 2020 | Research2020，，1： | 6 |
| 3 | Four Methods to Estimate Minimum Miscibility Pressure of CO2-Oil Based on Machine Learning显示文摘Summary of main observation and conclusion CO2 flooding accounts for a considerable proportion in gas flooding.Using CO2 as a gas displacement agent is benefit for enhanced oil recovery(EOR),and the alleviation of the greenhouse effect by the permanent storage of CO2 in the crust.Minimum miscibility pressure(MMP)of CO2-oil is a key factor affecting EOR,which determines the yield and economic benefit of crude oil recovery.Therefore,it is of great importance to use fast,accurate and cheap prediction methods for MMP estimation.In the present study,to evaluate the reliability of four recently developed prediction models based on machine learning(i.e.,neural network analysis(NNA),genetic function approximation(GFA),multiple linear regression(MLR),partial least squares(PLS)),136 sets of data are selected for calculation via outlier analysis from 147 sets of data.Afterwards,we compared the four models with existing prediction models from the literature.The analysis of correlation coefficients and multiple error functions shows that the four models can solve the MMP prediction problem well,and the model using intelligent algorithm has a higher prediction accuracy than the simple linear model.Besides,intelligent methods based on similarity algorithm have little difference from each other.Finally,a sensitivity analysis was conducted. | Ding Li Xiangliang Li Yinghua Zhang Lixin Sun Shiling Yuan | 2019 | Chinese Journal of Chemistry2019，37，12： | 4 |
| 4 | Ultrasensitive detection of aliphatic nitro-organics based on“turn-on”fluorescent sensor array显示文摘The broad class of explosives includes nitro aromatics as well as challenging aliphatic nitro-organics whose detection is important from counter-terrorism and national security perspectives.Here we report a turn-on fluorescent sensor array based on aggregation-induced emission(AIE)fluorophores as receptors.To achieve a good sensing system with fast response,good sensitivity and low detection limit,three receptors with abundant chemical diversities for target analytes were synthesized.The turn-on response of the individual receptor showed highly variable and cross-reactive analyte-dependent changes in fluorescence.The excellent ability to identify a variety of explosives,especially the challenging aliphatic nitro-organics(2,3-dimethyl-2,3-dinitrobutane(DMNB),1,3,5-trinitro-1,3,5-triazinane(RDX),cyclotetramethylene tetranitramine(HMX)and entaerythritol tetranitrate(PETN)),was demonstrated in qualitative and quantitative analyses with 100%accuracy.The fluorescence signal amplification in the presence of explosives allows for application of these receptors in a sensor microarray suitable for high-throughput screening.These results suggested that the cross-reactive sensor array based on AIE fluorophores could find a wide range of applications for sensing various analytes or complex mixtures. | Chen Wang Heng Zhang Li Tian Wei Zhu Yue Lan Jian Li Hui Wang Guanxin Zhang Deqing Zhang Shiling Yuan Guangtao Li | 2016 | Science China Chemistry2016，59，1： | 2 |
| 5 | Microstructure and properties of porous Si_(3)N_(4)ceramics by gelcasting-self-propagating high-temperature synthesis(SHS)显示文摘Porous silicon nitride ceramics have attracted a considerable attention due to their excellent overall performance,but poor porosity homogeneity and structural shrinkage induced by prolonged high temperature sintering limit its further application.Herein,as a three-in-one solution for the above issues,for the first time we develop a novel approach that integrates the merits of gelcasting-SHS(self-propagating high-temperature synthesis)to prepare porous Si_(3)N_(4)ceramics to simultaneously achieve high porosity,high strength,high toughness,and low thermal conductivity across a wide temperature range.By regulating the solid content,porous Si_(3)N_(4)ceramics with homogeneous pore structure are obtained,where the pore size falls inbetween 1.61 and 4.41 pm,and the elongated grains are interlaced and interlocked to form micron-sized coherent interconnected pores.At the same time,porous Si_(3)N_(4)ceramics with porosity of 67.83%to 78.03%are obtained,where the compressive strength reaches 11.79 to 47.75 MPa and fracture toughness reaches 1.20 to 6.71 MPa-m1/2. | Shile CHEN Liang WANG Gang HE Jiangtao LI Chang-An WANG | 2022 | Journal of Advanced Ceramics2022，11，1： | 2 |
| 6 | Comparative transcriptomic insights into the mechanisms of electron transfer in Geobacter co-cultures with activated carbon and magnetite显示文摘Both activated carbon and magnetite have been reported to promote the syntrophic growth of Geobacter metallireducens and Geobacter sulfurreducens co-cultures, the first model to show direct interspecies electron transfer (DIET); however, differential transcriptomics of the promotion on co-cultures with these two conductive materials are unknown. Here, the comparative transcriptomic analysis of G. metallireducens and G. sulfurreducens co-cultures with granular activated carbon (GAC) and magnetite was reported. More than 2.6-fold reduced transcript abundances were determined for the uptake hydrogenase genes of G. sulfurreducens as well as other hydrogenases in those co-cultures to which conductive materials had been added. This is consistent with electron transfer in G. metallireducens-G. sulfurreducens co-cultures as evinced by direct interspecies electron transfer (DIET). Transcript abundance for the structural component of electrically conductive pili (e-pili), PilA, was 2.2-fold higher in G. metallireducens, and, in contrast, was 14.9-fold lower in G. sulfurreducens in co-cultures with GAC than in Geobacters co-cultures without GAC. However, it was 9.3-fold higher in G. sulfurreducens in co-cultures with magnetite than in Geobacters co-cultures. Mutation results showed that GAC can be substituted for the e-pili of both strains but magnetite can only compensate for that of G. sulfurreducens, indicating that the e-pili is a more important electron acceptor for the electron donor strain of G. metallireducens than for G. sulfurreducens. Transcript abundance for G. metallireducens c-type cytochrome gene GMET_RS14535, a homologue to c-type cytochrome gene omcE of G. sulfurreducens was 9.8-fold lower in co-cultures with GAC addition, while that for OmcS of G. sulfurreducens was 25.1-fold higher in co-cultures with magnetite, than in that without magnetite. Gene deletion studies showed that neither GAC nor magnetite can completely substitute the cytochrome (OmcE homologous) of G. metallireducens but compensate for the cytochrome (OmcS) of G. sulfurreducens. Moreover, some genes associated with central metabolism were up-regulated in the presence of both GAC and magnetite; however, tricarboxylic acid cycle gene transcripts in G. sulfurreducens were not highly-expressed in each of these amended co-cultures, suggesting that there was considerable redundancy in the pathways utilised by G. sulfurreducens for electron transfer to reduce fumarate with the amendment of GAC or magnetite. These results support the DIET model of G. metallireducens and G. sulfurreducens and suggest that e-pili and cytochromes of the electron donor strain are more important than that of the electron acceptor strain, indicating that comparative transcriptomics may be a promising route by which to reveal different responses of electron donor and acceptor during DIET in co-cultures. | Shiling Zheng Fanghua Liu Meng Li Leilei Xiao Oumei Wang | 2018 | Science China(Life Sciences)2018，61，7： | 2 |
| 7 | Artesunate and Dihydroartemisinin Inhibit Rabies Virus Replication显示文摘Rabies is caused by infection of rabies virus(RABV)and remains a serious threat to the global public health.Except for the requirement for cold chain and high cost of human rabies immune globulin,no small molecule drugs are currently available for clinical treatment of rabies.So,it is of great importance to identify novel compounds that can effectively inhibit RABV infection.Artesunate(ART)and dihydroartemisinin(DHA),two derivatives of artemisinin,are widely used for treatment of malaria in adults and children,showing high safety.In this study,we found that both ART and DHA were able to inhibit RABV replication in host cells at a low concentration(0.1μmol/L).The antiviral effects of ART and DHA were independent of viral strains and cell lines.Pre-treatment with ART or DHA for 2 h in vitro did not affect the viral replication in host cells,implying that ART and DHA neither reduced the viability of RABV directly nor inhibited the binding and entrance of the virus to host cells.Further studies revealed that ART and DHA inhibited RABV genomic RNA synthesis and viral gene transcription.Treatment with ART or DHA(5 mg/kg)by intramuscular injection improved,to some extent,the survival rate of RABV-challenged mice.Combination treatment with derivatives of artemisinin and mannitol significantly improved the survival rate of RABV-challenged mice.The results suggest that ART and DHA have a great potential to be explored as new anti-rabies agents for treatment of rabies. | Jun Luo Yue Zhang Yang Wang Qing Liu Jiesen Li Hongling He Yongwen Luo Shile Huang Xiaofeng Guo | 2021 | Virologica Sinica2021，36，4： | 2 |
| 8 | Properties of a water layer on hydrophilic and hydrophobic self-assembled monolayer surfaces: A molecular dynamics study显示文摘The microscopic behaviors of a water layer on different hydrophilic and hydrophobic surfaces of well ordered self-assembled monolayers (SAMs) are studied by molecular dynamics simulations. The SAMs consist of 18-carbon alkyl chains bound to a silicon(111) substrate, and the characteristic of its surface is tuned from hydrophobic to hydrophilic by using different terminal functional groups ( CH 3 , COOH). In the simulation, the properties of water membranes adjacent to the surfaces of SAMs were reported by comparing pure water in mobility, structure, and orientational ordering of water molecules. The results suggest that the mobility of water molecules adjacent to hydrophilic surface becomes weaker and the molecules have a better ordering. The distribution of hydrogen bonds indicates that the number of water-water hydrogen bonds per water molecule tends to be lower. However, the mobility of water molecules and distribution of hydrogen bonds of a water membrane in hydropho- bic system are nearly the same as those in pure water system. In addition, hydrogen bonds are mainly formed between the hydroxyl of the COOH group and water molecules in a hydrophilic system, which is helpful in understanding the structure of interfacial water. | LI EnZe DU ZhiPing YUAN ShiLing | 2013 | Science China Chemistry2013，56，6： | 2 |
| 9 | Post-transcriptional gene silencing signal could move rapidly and bidirectionally in grafted Arabidopsis thaliana显示文摘RNA interference (RNAi), one of the newly found ways for post-transcriptional gene si- lencing, has been widely used to investigate gene functions through transgenic methods for introducing an RNA silencing signal into plants. In the present study, we constructed a dexamethazone (DEX)-inducible RNAi binary vector harboring a specific sequence fragment (168-bp) homologous to KatB and KatC, two kinesin isoform genes of Arabidopsis, which were proved to result in the post-transcriptional gene si- lencing of KatB and KatC in DEX-induced transgenic plants. RT-PCR and Northern blot analysis on trans- genic homozygous Arabidopsis (termed as RNAi-type plants) showed that DEX inducement causes KatB and KatC mRNA degradation. With a simplified method, Arabidopsis grafting was effectively per- formed between RNAi-type and wild-type lines. The target gene mRNA levels were tested based on semi-quantitative RT-PCR. Our results demonstrateed that DEX-induced gene silencing signals could result in a reduction in KatB and KatC mRNA in the wild-type rootstocks or scions, indicating that silencing signals of RNAi could be transmitted bidirectionally across the graft junction whether RNAi-plants were scions or stocks. In contrast to the previously reported results on grafted tobacco, the transmission of post- tran- scriptional gene silencing signals caused by RNAi in grafted Arabidopsis is more effective than that in to- bacco. | LI Ming JIANG Shiling WANG Youqun LIU Guoqin | 2006 | Chinese Science Bulletin2006，51，3： | 2 |

| 12 | Helium Bubble Growth in He^(+) Ions Implanted 304L Stainless Steel Processed by Laser Powder Bed Fusion During Post-Irradiation Annealing at 600℃显示文摘The abundancy of defect sinks in the microstructure of laser powder bed fusion(LPBF) processed austenitic stainless steels was found to be beneficial for helium resistance.In the current study,the influence of the novel microstructure in LPBF processed 304 L on the helium bubble growth behaviour was investigated using transmission electron microscopy in samples implanted with He^(+) ion and post-irradiation annealing treated at 600℃ for 1 h.Two variants of LPBF processed 304 L samples were used,one in as-built condition and the other solution-annealed.The comparison between the two samples indicated that the helium bubble growth was inhibited and remained stable in the as-built sample but coarsened significantly in the solution-annealed sample.The sub-grain boundaries and oxide nano-inclusions acted as defect sinks to trap helium atoms and inhibited the growth of helium bubble in the as-built sample under the post-irradiation annealing conditions used. | Hui Liu Shiling Min Menglei Jiang Fuzhong Chu Ying Li Zhuoer Chen Kai Zhang Juan Hou Aijun Huang | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，9： | 1 |
| 13 | C and N stable isotope analysis of human and animal bones at the Beiqian site显示文摘The Beiqian site,located in Jimo city,Qingdao,went through three archaeological excavations,and a large number of human and animal bones in the Dawenkou culture and the Zhou Dynasty period were unearthed.By carbon and nitrogen stable isotope analysis,the diet of ancestors is expected to be recovered,and the domesticated plants and animals will be discussed.The investigated results showed that the food structure of ancestors in both periods included food crops,mainly C4 foods,and meat,mainly marine shellfish and livestock.For domestic pigs,they mainly eat C3 plants,and were affected by the lifestyle of ancestors.This study also showed that the diet of ancestors is the shellfish rather than marine fish despite the Beiqian site is located near the shoreline.We can conclude that the diet of ancestors in Dawenkou culture period included millet crops(C4plants),shellfish,marine food,and livestock,representing the lifestyle of farming,domestication,and fishing,supplemented by hunting.In the Zhou dynasty period the meat resource was enriched by domesticated animals and marine fisheries,and the living conditions were significantly improved. | WANG Fen SONG YanBo LI BaoShuo FAN Rong JIN GuiYun YUAN ShiLing | 2014 | Science China Earth Sciences2014，57，3： | 1 |
| 14 | Designing regional pattern for ecosystem restoration:A case study显示文摘Designing regional pattern is challenging for ecosystem restoration both in theory and in practice. The present study proposed a new approach to design regional pattern for ecosystem restoration with a case in the arid valley of Upper Minjiang River, SW China. The procedures are: (1) Determine the regional pattern of main environmental factors based on the relationships between the important environmental factors and the main geographical factors generated from DEM data. (2) Overlay the maps of the main environmental factors. (3) Generate a lookup table according to the species selection rule we proposed to link the candidate restoration species to the main environmental factors.(4) Determine the regional pattern of ecosystem restoration by positioning the restoration species in the map of environmental factors according to the lookup table. The regional restoration pattern designed in this way would be applicable not only to restoring a region, but also to predicting the future landscape change. | LI Guoqiang , MA Keming, FU Bojie & LIU Shiling State Key Lab of Systems Ecology, Research Center for Eco-environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China Department of Water Environment, China Institute of Water Resources and Hydropower Research, Beijing 100038, China School of Environmental Sciences, Beijing Normal University, Beijing 100875, China | 2006 | Science China(Technological Sciences)2006，49，z1： | 1 |
| 15 | DFT study on second-order nonlinear optical properties of Pt (Ⅱ) complexes with different chromophores显示文摘DFT B3LYP/LANL2DZ method was employed to calculate electron properties and the second-order nonlinear optical(NLO) respond of platinum(Ⅱ) complexes which have been synthesized by Weinstein group.4,7-diphenyl-1,10-phenanthroline shows the ability to push electron in these complexes.Metal Pt plays a balancing charge role.Comparing complex 1b-6b with complex a,the βvec value of complex 1b-5b is larger than one of complex a,while the βvec value of complex 6b is smaller than one of com-plex a.In these seven complexes,the βvec values of complexes increase with decreasing of the energy difference between HOMO and LUMO.Moreover,the electron transfers from deeper layer occupied orbitals to empty orbitals have a distinct contribution to second-order NLO coefficient. | LIU XiaoDong,QIU YongQing,CHEN Hui,LI Na,SUN ShiLing & SU ZhongMin Institute of Functional Material Chemistry,Faculty of Chemistry,Northeast Normal University,Changchun 130024,China | 2009 | Science China Chemistry2009，52，2： | 1 |
| 16 | Reductive degradation of chloramphenicol by Geobacter metallireducens显示文摘Geobacter metallireducens is known to be capable of removing nitroaromatic compounds via an oxidation mode. However, little attention has been paid to investigate the reductive removal of chlorinated nitroaromatic compounds by G. metallireducens. In this study, G. metallireducens was used to reduce chloramphenicol(CAP), a typical chlorinated nitroaromatic antibiotic. Cyclic voltammograms and chronoamperometry highlighted a higher peak current for CAP reduction by G. metallireducens compared to the control without bacteria. G. metallireducens efficiently reduced CAP(20 mg/L) with acetate as the sole electron donor, and the removal efficiency reached(97.6±4.9)% within 6 d. Aromatic amine(AMCl2), AMCl(dechlorinated AMCl2) and AM(dechlorinated AMCl) were identified as reduction products by liquid chromatography-mass spectrometry. However, the removal efficiency declined to(25.0±3.6)% when the CAP dosage increased to 80 mg/L. Transcriptomic analysis indicated the significant upregulation of genes related to electron transfer, such as pilus assembly protein gene(2.8 folds), NADH-quinone oxidoreductase subunit K2 gene(4.5 folds) and many c-type cytochrome genes such as cytochrome c biogenesis protein Res B(Gmet 2901, 4.6 folds), cytochrome c(Gmet 0335, 4.4 folds) and cytochrome c7(Gmet 2902, 3.4 folds). Furthermore, a gene related to chlorinated contaminant removal(Gmet 1046, 5.4 folds) was also upregulated, possibly resulting in enhanced CAP reduction. This work deepened our knowledge of the bioremediation ability of G. metallireducens with respect to environmental contaminants and provided a potential strategy to treat antibiotics with electrochemically active bacteria. | XU HengDuo XIAO LeiLei ZHENG ShiLing ZHANG YueChao LI JiaJia LIU FangHua | 2019 | Science China(Technological Sciences)2019，62，10： | 0 |
| 17 | Interaction between dodecyl oxypropyl β-hydroxyltrimethylammonium bromide and Xanthan:MesoDyn simulation and binding isotherm measurements显示文摘MesoDyn density functional simulation method is used to study the interactions between dodecyl oxypropyl β-hydroxyltrimethylammonium bromide (C12NBr) and Xanthan (XC). The micro dynamic process of aggregate formation and the aggregate morphology are reported. Interaction between XC and nonyphenyloxypropyl β-hydroxyltrimethylammonium bromide (C9phNBr) is compared with that between XC and C12NBr. Simulation results show that the aggregate morphology of XC/C12NBr and XC/C9phNBr is of rod-like shape with helix characteristic. The binding of C9phNBr to XC is more difficult than that of C12NBr to XC. In addition, three stages for the dynamic evolution of surfactant binding to XC are observed. The simulation results agree with binding isotherms of C9phNBr (C12NBr) to XC obtained via the potentiometric titration method, which shows a typical cooperative binding between C9phNBr (C12NBr) and XC. | LI YiMing XU GuiYing CHEN AiMin DONG ShuLi YUAN ShiLing | 2007 | Chinese Science Bulletin2007，52，19： | 0 |

| 19 | Notoginsenoside Ft1 inhibits colorectal cancer growth by increasing CD8+T cell proportion in tumor-bearing mice through the USP9X signaling pathway显示文摘The management of colorectal cancer(CRC)poses a significant challenge,necessitating the development of innovative and effective therapeutics.Our research has shown that notoginsenoside Ft1(Ng-Ft1),a small molecule,markedly inhibits subcutaneous tumor formation in CRC and enhances the proportion of CD8+T cells in tumor-bearing mice,thus restraining tumor growth.Investigation into the mechanism revealed that Ng-Ft1 selectively targets the deubiquitination enzyme USP9X,undermining its role in shieldingβ-catenin.This leads to a reduction in the expression of downstream effectors in the Wnt signaling pathway.These findings indicate that Ng-Ft1 could be a promising small-molecule treatment for CRC,working by blocking tumor progression via the Wnt signaling pathway and augmenting CD8^(+)T cell prevalence within the tumor environment. | FENG Yutao LI Yuan MA Fen WU Enjiang CHENG Zewei ZHOU Shiling WANG Zhengtao YANG Li SUN Xun ZHANG Jiwei | 2024 | Chinese Journal of Natural Medicines2024，22，4： | 0 |
| 20 | Optical waveguides in LiNbO_3 and stoichiometric LiNbO_3 crystals by proton exchange显示文摘The formation of optical planar waveguides in LiNbO3 and stoichiometric LiNbO3 crystals by proton exchange was reported. The prism-coupling method was used to characterize the dark-line spectroscopy at the wavelength of 633 and 1539 nm, re-spectively. The mode optical near-field outputs from proton-exchanged LiNbO3 and SLN waveguides at 633 nm were presented. The mode field from stoichiometric LiNbO3 (SLN) waveguide is lighter and more uniform than that from LiNbO3 waveguide, which means the quality of the waveguide in SLN crystal is better than that of the LiNbO3 waveguide. For proton-exchanged LiNbO3 waveguides, the evo-lution of the refractive index profile with annealing was presented. The disorder profiles of Nb atoms in proton-exchanged LiNbO3 waveguides were obtained by Rutherford backscattering/channeling technique. It is shown that the longer the exchange time, the larger the displacement of Nb atoms. | LI ShiLing College of Physics and Engineering, Qufu Normal University, Qufu 273165, China School of Physics and Microelectronics, Shandong University, Jinan 250100, China | 2008 | Science China(Physics,Mechanics & Astronomy)2008，51，10： | 0 |
