| 2 | A novel comparative molecule/pseudo receptor interaction analysis显示文摘Comparative molecule/pseudo receptor interaction analysis (CoMPIA) is developed as a novel 3D-QSAR method by adding postulated pseudo receptor and GA-optimized probe into com- parative molecular field analysis (CoMFA). CoMPIA is used to find the pseudo receptor mode by opti- mizing probe distributions and to establish the opti- mal model of high qualities and good interpretations. Correlative coefficient R2, cross-validated correlative coefficient Q2 and root mean square error RMSEP of the resulting model are 0.940, 0.868 and 0.502, re- spectively by applying CoMPIA to quantitative struc- ture-activity relationship (QSAR) of 31 classical ster- oids. | ZHOU Peng TONG Jianbo TIAN Feifei LI Zhiliang | 2006 | Chinese Science Bulletin2006，51，15： | 5 |
| 3 | ESCRT-I Component VPS23A Sustains Salt Tolerance by Strengthening the SOS Module in Arabidopsis显示文摘The Salt-Overly-Sensitive(SOS)signaling module,comprising the sodium-transport protein SOS1 and the regulatory proteins SOS2 and SOS3,is well known as the central salt excretion system,which helps protect plants against salt stress.Here we report that VPS23A,a component of the ESCRT(endosomal sorting complex required for transport),plays an essential role in the function of the SOS module in conferring plant salt tolerance.VPS23A enhances the interaction of SOS2 and SOS3.In the presence of salt stress,VPS23A positively regulates the redistribution of SOS2 to the plasma membrane,which then activates the antiporter activity of SOS1 to reduce Na+accumulation in plant cells.Genetic evidence demonstrated that plant salt tolerance achieved by the overexpression of SOS2 and SOS3 dependeds on VPS23A.Taken together,our results revealed that VPS23A is a crucial regulator of the SOS module and affects the localization of SOS2 to the cell membrane.Moreover,the strong salt tolerance of Arabidopsis seedlings conferred by the engineered membrane-bound SOS2 revealed the significance of SOS2 sorting to the cell membrane in achieving its function,providing a potential strategy for crop salt tolerance engineering. | Lijuan Lou Feifei Yu Miaomiao Tian Guangchao Liu Yaorong Wu Yujiao Wu Ran Xia Jose M.Pardo Yan Guo Qi Xie | 2020 | Molecular Plant2020，13，8： | 5 |
| 4 | Effect of Li+ ion concentration on upconversion emission and temperature sensing behavior of La2O3:Er3+ phosphors显示文摘The effects of Li^+ co-doping concentration on the structure, upconversion luminescence and temperature sensing behavior of Er^(3+):La_2O_3 phosphors were investigated. X-ray diffraction and scanning electron microscopy observations reveal that Li^+ ion co-doping can change the lattice parameter of La_2O_3 host and increase the particle size of the samples. The optical investigation shows that co-doping of Li^+ ions can enhance the upconversion emission of Er^(3+) ions in La_2O_3 matrix effectively. Most importantly, the temperature sensing sensitivity of the samples is found to be dependent on Li^+ co-doping concentration,when the emission intensity ratio of the(~2H_(11/2)→~4 I_(15/2)) and(~4 S_(3/2)→~4 I_(15/2)) transitions of Er^(3+) is chosen as the thermometric index. Both of the optimum upconversion luminescence and temperature sensing sensitivity are obtained for 7 mol% Li^+ co-doped sample. When the Li^+ concentration is beyond 7 mol%,both the quenching in upconversion intensity and the degradation of temperature sensitivity are observed, which may be due to the serious distortion in local crystal field around Er^(3+) ions caused by the excess Li^+ ions. | Guangrun Chen Ruoshan Lei Shiqing Xu Huanping Wang Shilong Zhao Feifei Huang Yin Tian | 2018 | Journal of Rare Earths2018，36，2： | 4 |

| 6 | The electromechanical features of LiNbO_(3) crystal for potential high temperature piezoelectric applications显示文摘Lithium niobate(LiNbO_(3),LN)crystal is a multi-functional material with favorable piezoelectric,nonlinear optical and electro-optic properties.In this study,the electromechanical properties of the radial extensional(RE)and the thickness extensional(TE)modes of the congruent LN are studied and the temperature dependent behaviors are revealed.The RE mode electromechanical coupling factors(kp)for the Y-and Z-oriented discs are calculated and found to be 3.8%and 24.7%,respectively,which are nearly the same as the experimental results of 3.8%and 25.2%,respectively.The maximum RE and thickness shear(TS)modes electromechanical coupling factors are obtained to be 47.6%and 68.5%for the Yx/25and Yx/167crystal cuts,respectively.The LN crystal possesses good temperature stability of the electromechanical coupling factors(RE and TE modes)from 20℃ to 500℃,where the variations of kp and kt for the Y-oriented discs are<8.0%and<1.8%,respectively. | Feifei Chen Lingfeng Kong Wei Song Chao Jiang Shiwei Tian Fapeng Yu Lifeng Qin Xian Zhao | 2019 | Journal of Materiomics2019，5，1： | 3 |
| 7 | Applying generalized hydrophobicity scale of amino acids to quantitative prediction of human leukocyte antigen-A~*0201-restricted cytotoxic T lymphocyte epitope显示文摘Derived from 149 hydrophobic factors of 20 natural amino acids, a novel amino acid descriptor termed as generalized hydrophobicity scale (GH-scale) was proposed by principal component analysis (PCA). Via genetic algorithm-partial least square (GPLS) method, quantitative structure-activity relationship (QSAR) model was constructed by GH-scale for 152 human leukocyte antigen (HLA)-A*0201-restricted cytotoxic T lymphocyte (CTL) epitopes with the model estimated and cross-validated correlative coefficients of R2 = 0.813 and Q2 = 0.725, respectively. It was in- dicated that hydrophobic interaction played an im- portant role in HLA-A*0201-CTL interaction, promi- nently at anchor residues. | ZHOU Peng TIAN Feifei ZHANG Mengjun LI Zhiliang | 2006 | Chinese Science Bulletin2006，51，12： | 2 |
| 8 | Paleoclimatic evolution indicated by major geochemical elements from aeolian sediments on the east of Qinghai Lake显示文摘As the largest inland lake of China, along with its unique landscape and geographical location, Qinghai Lake has got much atten- tion of the scientists for a long time. The precursors have done substantive researches by using the lake sediment, which deepen our understanding of the climate changes in this region. Although sand dunes and loess sediment are widely distributed around the lake, so far the researches on geochemical elements from aeolian sediment have been less reported. In this paper, we selected a typical aeolian profile on the east of Qinghai Lake. Based on systematic sampling and analysis of seven major geochemical elements, combined with OSL dating and previous researches, this paper discusses climate changes in the Qinghai Lake area since 12.5 ka B.P.. Our conclusions are: (1) Before 12.5 ka B.P., the climate in this region was dry, cold, and accompanied by strong wind-sand activities. (2) During 12.5-11.9 ka B.P., the climate became warm and wet. However, there was an abrupt climate cooling event during 12.2-11.9 ka B.P., which likely corresponded to the Younger Dryas event. (3) During 11.9-8.0 ka B.P., the climate fluctuated greatly and frequently from warm to cold, and three cooling events occurred. (4) During 8.0-2.6 ka B.P., the climate was warm and humid. (5) Since 2.6 ka B.P., similar to the modern climate, the climate was mainly dry and cold. | Yuan Shang RuiJie Lu FeiFei Jia LiHui Tian QingLiang Tang Yuan Chen Chao Zhao WangYang Wu | 2013 | Research in Cold and Arid Regions2013，5，3： | 2 |
| 9 | Research and development of a novel subunit vaccine for the currently circulating pseudorabies virus variant in China显示文摘Pseudorabies(PR)is a devastating viral disease which leads to fatal encephalitis and respiratory disorders in pigs.Commercial gE-deleted live pseudorabies virus(PRV)vaccine has been widely used to control this disease in China.However,the new-emerging variants of PRV compromises the protection provided by current vaccines and lead to the outbreak of PR in vaccinated pig herds.Several killed and live vaccine candidates based on current PRV variants have been reported to be effective to control the disease.A subunit vaccine based on gB protein,one major PRV glycoprotein which elicits strong humoral and cellular immune responses,however,was never evaluated for protection against the current circulating PRV variants.In this study,full-length PRV gB protein was successfully expressed in baculovirus/insect cells in the soluble format and was tested on 3-week-old piglets as a subunit vaccine.Compared with unvaccinated pigs,the gB-vaccinated pigs developed specific antibody-mediated responses and were protected from the virulent PRV HN1201 challenge.All vaccinated pigs survived without showing any PRV-specific respiratory and neurological signs,but all unvaccinated pigs died within 7 days after HN1201 challenge.Hence,this novel gB-based vaccine could be applied as an effective subunit vaccine to control PRV variant in China. | Yuzhou WANG Tongyan WANG He YAN Fanli YANG Linghua GUO Qingyuan YANG Xule HU Feifei TAN Yan XIAO Xiangdong LI Kegong TIAN | 2015 | Frontiers of Agricultural Science and Engineering2015，2，3： | 2 |
| 10 | Proper animal experimental designs for preclinical research of biomaterials for intervertebral disc regeneration显示文摘Low back pain is a vital musculoskeletal disease that impairs life quality,leads to disability and imposes heavy economic burden on the society,while it is greatly attributed to intervertebral disc degeneration(IDD).However,the existing treatments,such as medicines,chiropractic adjustments and surgery,cannot achieve ideal disc regeneration.Therefore,advanced bioactive therapies are implemented,including stem cells delivery,bioreagents administration,and implantation of biomaterials etc.Among these researches,few reported unsatisfying regenerative outcomes.However,these advanced therapies have barely achieved successful clinical translation.The main reason for the inconsistency between satisfying preclinical results and poor clinical translation may largely rely on the animal models that cannot actually simulate the human disc degeneration.The inappropriate animal model also leads to difficulties in comparing the efficacies among biomaterials in different reaches.Therefore,animal models that better simulate the clinical charateristics of human IDD should be acknowledged.In addition,in vivo regenerative outcomes should be carefully evaluated to obtain robust results.Nevertheless,many researches neglect certain critical characteristics,such as adhesive properties for biomaterials blocking annulus fibrosus defects and hyperalgesia that is closely related to the clinical manifestations,e.g,low back pain.Herein,in this review,we summarized the animal models established for IDD,and highlighted the proper models and parameters that may result in acknowledged IDD models.Then,we discussed the existing biomaterials for disc regeneration and the characteristics that should be considered for regenerating different parts of discs.Finally,well-established assays and parameters for in vivo disc regeneration are explored. | Yizhong Peng Xiangcheng Qing Hongyang Shu Shuo Tian Wenbo Yang Songfeng Chen Hui Lin Xiao Lv Lei Zhao Xi Chen Feifei Pu Donghua Huang Xu Cao Zengwu Shao | 2021 | Biomaterials Translational2021，2，2： | 2 |

| 12 | Electrical properties of yttrium calcium oxyborate crystal annealed at high temperature and low oxygen partial pressure显示文摘The yttrium calcium oxyborate crystal(YCa_(4)O(BO_(3))_(3),YCOB)has been actively studied for hightemperature piezoelectric sensing applications.In this work,the stability of electric properties of YCOB crystal annealed in critical conditions(high-temperatures of 900-1100℃ with a low oxygen partial pressure of 4×10^(-6) atm for 24 h)was investigated and the recovery mechanism for the electrical resisitivity,dielectric permittivity and dielectric loss were studied,taking advantage of the X-ray photoelectron spectra and the first principle calculations.The electrical resistivity of the annealed YCOB crystal was slightly decreased when compared to the pristine counterpart,being(2-5)×10^(7) Ω·cm at 850C.The dielectric permittivity and dielectric loss were found to increase after annealing,showing recoverable behaviours after thermal treatment above 650℃ in air.The calculated vacancy formation energy indicates that the oxygen vacancy is the dominant defects in YCOB.The formation of oxygen vacancy weakens the chemical bonding strength between B(Ca or Y)and O atoms,introduces extra donor levels in the band gap,which excites the electrons to conduction band more easily thus enhances the electrical conductivity and dielectric loss.The recovered electrical properties are believed to be associated with the reduced vacancy defects at elevated temperatures in air. | Shiwei Tian Lili Li Feifei Chen Chao Jiang Fapeng Yu Yanlu Li Xiulan Duan Zhengping Wang Shujun Zhang Xian Zhao | 2019 | Journal of Materiomics2019，5，3： | 2 |
| 13 | Pulse-width-induced polarization enhancement of optically pumped N-V electron spin in diamond显示文摘The nitrogen-vacancy(N-V)center in diamond is a widely used platform for quantum information processing and sensing.The electron-spin state of the N-V center could be initialized,read out optically,and manipulated by resonate microwave fields.In this work,we analyze the dependence of electron-spin initialization on widths of laser pulses.We build a numerical model to simulate this process and to verify the simulation results in experiments.Both simulations and experiments reveal that shorter laser pulses are helpful to the electron-spin polarization.We therefore propose to use extremely short laser pulses for electron-spin initialization.In this new scheme,the spin-state contrast could be improved about 10%in experiments by using laser pulses as short as 4 ns in width.Furthermore,we provide a mechanism to explain this effect,which is due to the occupation time in the meta-stable spin-singlet states of the N-V center.Our new scheme is applicable in a broad range of N-V-based applications in the future. | YUMENG SONG YU TIAN ZHIYI HU FEIFEI ZHOU TENGTENG XING DAWEI LU BING CHEN YA WANG NANYANG XU JIANGFENG DU | 2020 | Photonics Research2020，8，8： | 1 |

| 16 | N-Glycoproteomics Study of Putative N-Glycoprotein Biomarkers of Drug Resistance in MCF-7/ADR Cells显示文摘Currently,drug resistance of anti-cancer therapy has become the main cause of low survival rate and poor prognosis.Full understanding of drug resistance mechanisms is an urgent request for further development of anti-cancer therapy and improve-ment of prognosis.Here we present our N-glycoproteomics study of putative N-glycoprotein biomarkers of drug resistance in doxorubicin resistance breast cancer cell line michigan cancer foundation-7(MCF-7/ADR)relative to parental michigan cancer foundation-7(MCF-7)cells.Intact N-glycopeptides(IDs)from MCF-7/ADR and MCF-7 cells were enriched with zwitterionic hydrophilic interaction liquid chromatography(ZIC-HILIC),labeled with stable isotopic diethylation(SIDE),and analyzed with C18-RPLC-MS/MS(HCD with stepped normalized collision energies);these IDs were identified with database search engine GPSeeker,and the differentially expressed intact N-glycopeptides(DEGPs)were quantified with GPSeekerQuan.With target-decoy searches and control of spectrum-level FDR≤1%,322 intact N-glycopeptides were identified;these intact N-glycopeptides come from the combination of 249 unique peptide backbones(corresponding to 234 intact N-glycoproteins)and 90 monosaccharide compositions(corresponding to 248 putative N-glycosites).The sequence structures of 165 IDs were confirmed with structure-diagnostic fragment ions.With the criteria of observation at least twice among the three technical replicates,≥1.5-fold change and p value<0.05,20 DEGPs were quantified,where five of them were up-regulated and 15 of them were down-regulated;the corresponding intact N-glycoproteins as putative markers of drug resistance were discussed. | Hailun Yang Feifei Xu Kaijie Xiao Yun Chen Zhixin Tian | 2021 | Phenomics2021，1，6： | 1 |
| 17 | Resistive switching and artificial synaptic performances of memristor based on low-dimensional bismuth halide perovskites显示文摘Zero-dimensional(0D)-Cs_(3)Bi_(2)I_(9),two-dimensional(2D)-Cs_(3)Bi_(2)Br_(9),and one-dimensional(1D)-Cs3Bi2Cl9 perovskite films have been successfully grown on indium tin oxide(ITO)glass substrates,which were used to fabricate memristors with the structure of Al/Cs_(3)Bi_(2)X_(9)(X=I,Br,and Cl)/ITO glass.The current three types of memristors exhibited bipolar resistive switching behaviors.Both the endurance and retention time tests clearly demonstrated the excellent stability of present devices.Especially,the ON/OFF ratio of the 0D-Cs_(3)Bi_(2)I_(9)device is close to 104 at the reading voltage of 0.1 V,which is nearly 100 and 1000 times larger than those of the 1D-Cs3Bi2Cl9 device and the 2D-Cs_(3)Bi_(2)Br_(9)device,respectively.The activation energy of halide vacancies in the Cs_(3)Bi_(2)X_(9)(X=I,Br,and Cl)films was calculated using the density functional theory by considering a minimum migration path,demonstrating the dimensionality of the Cs_(3)Bi_(2)X_(9)(X=I,Br,and Cl)film affected the formation and rupture of conductive filaments.Moreover,the short-term plasticity and long-term plasticity of biological synapse were simulated by evaluating the conductance responses of Al/Cs_(3)Bi_(2)X_(9)(X=I,Br,and Cl)/ITO devices under various voltage pulses in detail.The duration time of long-term plasticity in all the present devices can last for up to 250 s.The 0D-Cs_(3)Bi_(2)I_(9)device showed both the highest spikeduration-dependent plasticity and paired-pulse facilitation indexes compared to the other two devices.Additionally,the 0DCs_(3)Bi_(2)I_(9)device successfully established the associative learning behavior by simulating the Pavlov’s dog experiment. | Feifei Luo Yanzhao Wu Junwei Tong Fubo Tian Xianmin Zhang | 2023 | Nano Research2023，16，7： | 1 |

| 19 | Endogenous repair theory enriches construction strategies for orthopaedic biomaterials:a narrative review显示文摘The development of tissue engineering has led to new strategies for mitigating clinical problems;however,the design of the tissue engineering materials remains a challenge.The limited sources and inadequate function,potential risk of microbial or pathogen contamination,and high cost of cell expansion impair the efficacy and limit the application of exogenous cells in tissue engineering.However,endogenous cells in native tissues have been reported to be capable of spontaneous repair of the damaged tissue.These cells exhibit remarkable plasticity,and thus can differentiate or be reprogrammed to alter their phenotype and function after stimulation.After a comprehensive review,we found that the plasticity of these cells plays a major role in establishing the cell source in the mechanism involved in tissue regeneration.Tissue engineering materials that focus on assisting and promoting the natural self-repair function of endogenous cells may break through the limitations of exogenous seed cells and further expand the applications of tissue engineering materials in tissue repair.This review discusses the effects of endogenous cells,especially stem cells,on injured tissue repairing,and highlights the potential utilisation of endogenous repair in orthopaedic biomaterial constructions for bone,cartilage,and intervertebral disc regeneration. | Yizhong Peng Jinye Li Hui Lin Shuo Tian Sheng Liu Feifei Pu Lei Zhao Kaige Ma Xiangcheng Qing Zengwu Shao | 2021 | Biomaterials Translational2021，2，4： | 1 |
