| 1 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
| 2 | Mapping the permafrost stability on the Tibetan Plateau for 2005–2015显示文摘Data scarcity is a major obstacle for high-resolution mapping of permafrost on the Tibetan Plateau(TP).This study produces a new permafrost stability distribution map for the 2010 s(2005–2015)derived from the predicted mean annual ground temperature(MAGT)at a depth of zero annual amplitude(10–25 m)by integrating remotely sensed freezing degree-days and thawing degree-days,snow cover days,leaf area index,soil bulk density,high-accuracy soil moisture data,and in situ MAGT measurements from 237 boreholes on the TP by using an ensemble learning method that employs a support vector regression model based on distance-blocked resampled training data with 200 repetitions.Validation of the new permafrost map indicates that it is probably the most accurate of all currently available maps.This map shows that the total area of permafrost on the TP,excluding glaciers and lakes,is approximately 115.02(105.47–129.59)×10^4 km^2.The areas corresponding to the very stable,stable,semi-stable,transitional,and unstable types are 0.86×10^4,9.62×10^4,38.45×10^4,42.29×10^4,and 23.80×10^4 km^2,respectively.This new map is of fundamental importance for engineering planning and design,ecosystem management,and evaluation of the permafrost change in the future on the TP as a baseline. | Youhua RAN Xin LI Guodong CHENG Zhuotong NAN Jinxing CHE Yu SHENG Qingbai WU Huijun JIN Dongliang LUO Zhiguang TANG Xiaobo WU | 2021 | Science China Earth Sciences2021，64，1： | 11 |

| 4 | 声波激励的超小型纳机电系统磁电天线显示文摘当前的小型天线依赖于电磁波的谐振,因此天线的尺寸与电磁波波长相关。典型的天线尺寸大于波长的1/10,而进一步缩小天线尺寸在近十年来都是一个公开的挑战。介绍一种通过悬浮铁氧/压电薄膜异质结构的声波激励纳机械磁电天线。这种磁电天线通过其在声波谐振频率处的磁电效应接收和发射电磁波。磁电天线中的体声波激发铁磁薄膜的磁化振荡,产生电磁波的辐射;反之,天线感应电磁波的磁场,得到压电电压输出。这种磁电天线(尺寸仅为波长的千分之一)比现有小型天线的尺寸小1到2个数量级,但性能却没有降低,在便携式无线通信系统中具有很大的应用潜力。 | Tianxiang Nan Hwaider Lin Yuan Gao Alexei Matyushov Guoliang Yu Huaihao Chen Neville Sun Shengjun Wei Zhiguang Wang Menghui Li Xinjun Wang Amine Belkessam Rongdi Guo Brian Chen James Zhou Zhenyun Qian Yu Hui Matteo Rinaldi Michael E.McConney BrANDon M.Howe Zhongqiang Hu John G.Jones Gail J.Brown Nian Xiang Sun 张建强(翻译) 陈鼎鼎(审校) | 2017 | 通信对抗2017，36，4： | 8 |
| 5 | A 3D-Bioprinted dual growth factor-releasing intervertebral disc scaffold induces nucleus pulposus and annulus fibrosus reconstruction显示文摘Regeneration of Intervertebral disc(IVD)is a scientific challenge because of the complex structure and composition of tissue,as well as the difficulty in achieving bionic function.Here,an anatomically correct IVD scaffold composed of biomaterials,cells,and growth factors were fabricated via three-dimensional(3D)bioprinting technology.Connective tissue growth factor(CTGF)and transforming growth factor-β3(TGF-β3)were loaded onto polydopamine nanoparticles,which were mixed with bone marrow mesenchymal stem cells(BMSCs)for regenerating and simulating the structure and function of the nucleus pulposus and annular fibrosus.In vitro experiments confirmed that CTGF and TGF-β3 could be released from the IVD scaffold in a spatially controlled manner,and induced the corresponding BMSCs to differentiate into nucleus pulposus like cells and annulus fibrosus like cells.Next,the fabricated IVD scaffold was implanted into the dorsum subcutaneous of nude mice.The reconstructed IVD exhibited a zone-specific matrix that displayed the corresponding histological and immunological phenotypes:primarily type II collagen and glycosaminoglycan in the core zone,and type I collagen in the surrounding zone.The testing results demonstrated that it exhibited good biomechanical function of the reconstructed IVD.The results presented herein reveal the clinical application potential of the dual growth factors-releasing IVD scaffold fabricated via 3D bioprinting.However,the evaluation in large mammal animal models needs to be further studied. | Binbin Sun Meifei Lian Yu Han Xiumei Mo Wenbo Jiang Zhiguang Qiao Kerong Dai | 2021 | Bioactive Materials2021，6，1： | 5 |
| 6 | A CRISPR/Cas12a-empowered surface plasmon resonance platform for rapid and specific diagnosis of the Omicron variant of SARS-CoV-2显示文摘The outbreak of the COVID-19 pandemic was partially due to the challenge of identifying asymptomatic and presymptomatic carriers of the virus,and thus highlights a strong motivation for diagnostics with high sensitivity that can be rapidly deployed.On the other hand,several concerning SARS-CoV-2 variants,including Omicron,are required to be identified as soon as the samples are identified as‘positive’.Unfortunately,a traditional PCR test does not allow their specific identification.Herein,for the first time,we have developed MOPCS(Methodologies of Photonic CRISPR Sensing),which combines an optical sensing technology-surface plasmon resonance(SPR)with the‘gene scissors’clustered regularly interspaced short palindromic repeat(CRISPR)technique to achieve both high sensitivity and specificity when it comes to measurement of viral variants.MOPCS is a low-cost,CRISPR/Cas12a-systemempowered SPR gene-detecting platform that can analyze viral RNA,without the need for amplification,within 38 min from sample input to results output,and achieve a limit of detection of 15 fM.MOPCS achieves a highly sensitive analysis of SARS-CoV-2,and mutations appear in variants B.1.617.2(Delta),B.1.1.529(Omicron)and BA.1(a subtype of Omicron).This platform was also used to analyze some recently collected patient samples from a local outbreak in China,identified by the Centers for Disease Control and Prevention.This innovative CRISPR-empowered SPR platform will further contribute to the fast,sensitive and accurate detection of target nucleic acid sequences with single-base mutations. | Zhi Chen Jingfeng Li Tianzhong Li Taojian Fan Changle Meng Chaozhou Li Jianlong Kang Luxiao Chai Yabin Hao Yuxuan Tang Omar AAl-Hartomy Swelm Wageh Abdullah GAl-Sehemi Zhiguang Luo Jiangtian Yu Yonghong Shao Defa Li Shuai Feng William J.Liu Yaqing He Xiaopeng Ma Zhongjian Xie Han Zhang | 2022 | National Science Review2022，9，8： | 3 |

| 8 | Flutter and Thermal Buckling Properties and Active Control of Functionally Graded Piezoelectric Material Plate in Supersonic Airflow显示文摘This paper is devoted to investigate the flutter and thermal buckling properties of the functionally graded piezoelectric material(FGPM)plate in supersonic airflow,and the active flutter control is carried out under different temperature fields.The piezoelectric material component of the FGPM plate has gradient changes along the thickness,such as piezoelectricity and dielectric coefficients.The supersonic piston theory is used to evaluate the aerodynamic pressure.Based on the first-order shear deformation theory and Hamilton’s principle with the assumed mode method,the equation of motion of the structural system is deduced.The effect of aerodynamic pressure on the frequency and damping ratio of the FGPM plate is analyzed.Moreover,the flutter and thermal buckling properties of the FGPM and pure metal plates are compared to show the superior aerothermoelastic properties of the FGPM plates.The influences of volume fraction exponent and temperature on the flutter and thermal buckling properties of the FGPM plate are also examined in detail.The LQR controller is adopted to achieve active flutter control.The simulation results show that the present control method can largely improve dynamic stability of the FGPM plate in supersonic airflow and high-temperature environment. | Yu Xue Jinqiang Li Fengming Li Zhiguang Song | 2020 | Acta Mechanica Solida Sinica2020，33，5： | 2 |
| 9 | CRISPR-Cas12a-Empowered Electrochemical Biosensor for Rapid and Ultrasensitive Detection of SARS-CoV-2 Delta Variant显示文摘Coronavirus disease 2019(COVID-19)is a highly contagious disease caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2).The gold standard method for the diagnosis of SARS-CoV-2 depends on quantitative reverse transcription-polymerase chain reaction till now,which is time-consuming and requires expensive instrumentation,and the confirmation of variants relies on further sequencing techniques.Herein,we first proposed a robust technique-methodology of electrochemical CRISPR sensing with the advantages of rapid,highly sensitivity and specificity for the detection of SARS-CoV-2 variant.To enhance the sensing capability,gold electrodes are uniformly decorated with electro-deposited gold nanoparticles.Using DNA template identical to SARS-CoV-2 Delta spike gene sequence as model,our biosensor exhibits excellent analytical detection limit(50 fM)and high linearity(R2=0.987)over six orders of magnitude dynamic range from 100 fM to 10 nM without any nucleic-acid-amplification assays.The detection can be completed within 1 h with high stability and specificity which benefits from the CRISPR-Cas system.Furthermore,based on the wireless micro-electrochemical platform,the proposed biosensor reveals promising application ability in point-of-care testing. | Chenshuo Wu Zhi Chen Chaozhou Li Yabin Hao Yuxuan Tang Yuxuan Yuan Luxiao Chai Taojian Fan Jiangtian Yu Xiaopeng Ma Omar AAl-Hartomy SWageh Abdullah GAl-Sehemi Zhiguang Luo Yaqing He Jingfeng Li Zhongjian Xie Han Zhang | 2022 | Nano-Micro Letters2022，14，10： | 2 |
| 10 | High-precision,gelatin-based,hybrid,bilayer scaffolds using melt electro-writing to repair cartilage injury显示文摘Articular cartilage injury is a common disease in the field of orthopedics.Because cartilage has poor self-repairing ability,medical intervention is needed.Using melt electro-writing(MEW)technology,tissue engineering scaffolds with high porosity and high precision can be prepared.However,ordinary materials,especially natural polymer materials,are difficult to print.In this study,gelatin was mixed with poly(lactic-co-glycolic acid)to prepare high-concentration and high-viscosity printer ink,which had good printability and formability.A composite scaffold with full-layer TGF-β1 loading mixed with hydroxyapatite was prepared,and the scaffold was implanted at the cartilage injury site;microfracture surgery was conducted to induce the mesenchyme in the bone marrow.Quality stem cells thereby promoted the repair of damaged cartilage.In summary,this study developed a novel printing method,explored the molding conditions based on MEW printing ink,and constructed a bioactive cartilage repair scaffold.The scaffold can use autologous bone marrow mesenchymal stem cells and induce their differentiation to promote cartilage repair. | Yu Han Bo Jia Meifei Lian Binbin Sun Qiang Wu Benlin Sun Zhiguang Qiao Kerong Dai | 2021 | Bioactive Materials2021，6，7： | 2 |
| 11 | Diagnostic criteria of latent autoimmune diabetes in adults(LADA):a review and reflection显示文摘Diabetes has become a major public health problem in China nowadays.There are almost 97 million diabetic patients nationwide.Latent autoimmune diabetes in adults(LADA)is a subtype of autoimmune diabetes.Although it has been reported for about 20 years,the diagnostic criteria of this disease remain controversial.The discussion mainly focused on serum autoantibodies,period of insulin need and age of diagnosis.Besides,β cell function,metabolic parameters,genetic factors and cell immunity may also contribute to the formulation of the criteria.Here,we aim to review and discuss the diagnostic criteria of latent autoimmune diabetes in adults. | Yu Liao Yufei Xiang Zhiguang Zhou | 2012 | Frontiers of Medicine2012，6，3： | 2 |
| 12 | Reduced salinity interacts with ultraviolet radiation to alter photosystem Ⅱ function in diatom Skeletonema costatum显示文摘To investigate the effect of reduced salinity on diatoms’ capacity to cope with changing ultraviolet radiation(U VR) and photosynthetically active radiation(PAR),Skeletonema costatum was grown in a range of salinity(15,25,and 35).The photo system Ⅱ(PSⅡ) function was analyzed by increasing PAR and UVR to mimic a mixing event in turbulent waters.The re sults show that high UVR exposure significantly reduced PSII activity,especially in cells grown at low salinity.UVR,but not salinity,stimulated the ’removal’ rate of PSII protein PsbA.Salinity alone,in the range of 15 to 35,did not regulate PSⅡ acceptor region;however,the low salinity+UVR treatment decreased the energy flux for electron transport per PSⅡ reaction center in S.costatum.It showed that low salinity exacerbated the damaging effect of UVR on PSⅡ function in S.costatum by suppressing Psb A protein synthe sis and modifying the photochemistry of PSⅡ.Although higher catalase(CAT) activity and NPQs were induced,they were unable to prevent the combined damage effect of low salinity+UVR.Our findings indicate that reduced salinity and increased UVR potentially affect the abundance and distribution of S.costatum with the escalation of climate disturbances. | Shasha ZANG Fang YAN Daode YU Jingjing SONG Lei WANG Zhiguang XU Hongyan WU | 2022 | Journal of Oceanology and Limnology2022，40，4： | 1 |
| 13 | Cascaded multilayer nano-kirigami for extensible 3D nanofabrication and visible light manipulation显示文摘Nano-kirigami enables direct and versatile shape transformations from two-dimensional predesigns to threedimensional(3 D)architectures in microscale/nanoscale.Here a new and extensible strategy for cascaded multilayer nano-kirigami is demonstrated in a gold/silicon nitride(Au/SiN)bilayer nanofilm for 3 D nanofabrication and visible light manipulation.By employing a focused ion-beam-based Boolean irradiation,rich 3 D shape transformation and nested multilayer nanostructures are precisely manufactured,which are well reproduced by developing a modified mechanical model.Based on the multilayer and deformable features of the nano-kirigami structures,potentials in manipulating the phase and intensity of visible light are explored.The developed new nano-kirigami strategies,as well as the novel exotic 3 D nanostructures,could be helpful to build a novel platform for 3 D nanofabrication and find potential applications in microelectromechanical/nanoelectromechanical systems,holographic display,plasmonics,nanophotonics,biophotonics,etc. | YU HAN ZHIGUANG LIU SHANSHAN CHEN JUAN LIU YONGTIAN WANG AND JIAFANG LI | 2020 | Photonics Research2020，8，9： | 1 |
| 14 | Engineered high-strength biohydrogel as a multifunctional platform to deliver nucleic acid for ameliorating intervertebral disc degeneration显示文摘Intervertebral disc degeneration(IVDD)is a leading cause of low back pain.The strategy of using functional materials to deliver nucleic acids provides a powerful tool for ameliorating IVDD.However,the immunogenicity of nucleic acid vectors and the poor mechanical properties of functional materials greatly limit their effects.Herein,antagomir-204-3p(AM)shows low immunogenicity and effectively inhibits the apoptosis of nucleus pulposus cells.Moreover,a high-strength biohydrogel based on zinc-oxidized sodium alginate-gelatin(ZOG)is designed as a multifunctional nucleic acid delivery platform.ZOG loaded with AM(ZOGA)exhibits great hygroscopicity,antibacterial activity,biocompatibility,and biodegradability.Moreover,ZOGA can be cross-linked with nucleus pulposus tissue to form a high-strength collagen network that improves the mechanical properties of the intervertebral disc(IVD).In addition,ZOGA provides an advantageous microenvironment for genetic expression in which AM can play an efficient role in maintaining the metabolic balance of the extracellular matrix.The results of the radiological and histological analyses demonstrate that ZOGA restores the height of the IVD,retains moisture in the IVD,and maintains the tissue structure.The ZOGA platform shows the sustained release of nucleic acids and has the potential for application to ameliorate IVDD,opening a path for future studies related to IVD. | Tao Chen Qiuping Qian Pooyan Makvandi Ehsan Nazarzadeh Zare Qizhu Chen Linjie Chen Zhiguang Zhang Hao Zhou Wenxian Zhou Hui Wang Xiangyang Wang Yu Chen Yunlong Zhou Aimin Wu | 2023 | Bioactive Materials2023，，7： | 1 |
| 15 | Postoperative infection caused by Acinetobacter baumannii misdiagnosed as a free-living amoeba species in a humeral head hemiarthroplasty patient:a case report显示文摘Background:Acinetobacter baumannii is ubiquitous,facultative intracellular,and opportunistic bacterial pathogen.Its unique abilities allow it to survive in a diverse range of environments,including health care settings,leading to nosocomial infections.And its exceptional ability to develop resistance to multiple antibiotics leaves few drug options for treatment.It has been recognized as a leading cause of nosocomial pneumonia and bacteremia over the world.Case presentation:In this case,a 73-year-old woman presented with a Neer Group VI proximal humeral fracture.Six hours after a successfully performed hemiarthroplasty,she developed continuous fever.Clinical examination revealed that the vitals were regular.Laboratory and radiographic examinations revealed only elevated procalcitonin levels.Blood culture revealed no bacterial or fungal growth.Cooling treatment and empirical broad-spectrum antibiotic therapy showed no apparent effect.Conclusions:We report a postoperative infection caused by Acinetobacter baumannii.The infectious pathogen was identified via molecular DNA sequencing and was initially misidentified as a free-living amoeba species upon microscopic examinations.The patient was mistreated with antiamebic combination therapy.Her symptoms persisted for over 4 months and were eventually followed by her death. | Jiaxin Tang Huaimin Zhu Li Cai Tingting Tang Jian Tang Yuehua Sun Ming Liu Kerong Dai Zhiguang Qiao Chao Yu | 2018 | Infectious Diseases of Poverty2018，7，1： | 1 |
| 16 | Flexible and flame-retarding phosphorylated MXene/polypropylene composites for efficient electromagnetic interference shielding显示文摘Flame-retardant composites with high electromagnetic interference(EMI)shielding performance are desirable for electronic device packaging.Despite great potential of MXene for high EMI,it still remains a great challenge to develop high-performance flame-retardant polymer/MXene composites with excellent EMI shielding effectiveness because of the poor oxidative stability of MXene.Herein,phosphorylated MXene/polypropylene(PP)composites are prepared by coating phosphorylated MXene on PP fabric followed by spraying polyethylenimine(PEI)and hot-pressing.The phosphorylated MXene proves to be more durable against oxidation than pure MXene due to the protection effect of polyphosphates.Upon hot-pressing,melted PP fibers are fused together at their contact points and thus as-prepared composites are bi-continuous with two interpenetrating phases.The composites show significantly improved thermal stability and flame retardancy relative to pure PP,with a low total heat release(THR)of 3.7 kJ/g and a heat release rate(HRR)of 50.0 W/g,which are reduced by 78%and 87%,respectively.In addition,the composites exhibit a high electrical conductivity of~36,700 S/m and an EMI shielding performance of~90 d B over the whole frequency range of 8–12 GHz with a thickness of~400μm.The as-developed PP/MXene composites hold great promise for reliable protection of next-generation electronic devices working in complex environments. | Tingting Tang Shanchi Wang Yue Jiang Zhiguang Xu Yu Chen Tianshu Peng Fawad Khan Jiabing Feng Pingan Song Yan Zhao | 2022 | Journal of Materials Science & Technology2022，，16： | 1 |
| 17 | Stability improvement of human collagenα1(I)chain using insulin as a fusion partner显示文摘To enhance the stability of recombinant human collagen α1(I) chains(rhCOL1 A1) in production and purification stages, a gene fragment fusing COL1 A1 and insulin protein coding domains was synthesized and inserted into the pPIC9 K expression vector. The fusion peptide-expressing Pichia pastoris strain was created by transformation.After optimization of shake flask cultures, the ultimate intracellular expression level of the insulin-collagen α1(I) chain fusion protein(INS-COL1 A1) reached about 300 mg·L^(-1), and no obvious protein degradation was found in the fermentation and purification processes. The His-tagged recombinant fusion protein was detected by western blotting and was effectively purified using Ni^(2+)-chelating chromatography. A prominent improvement in the stability of INS-COL1 A1 was observed compared to rhCOL1 A1 in vitro, and the rhCOL1 A1 released from the fusion protein was studied by LC–MS/MS and in bioassays. The results showed that the purified rhCOL1 A1 was consistent with the native protein in amino acid composition and had a similar biological compatibility. To our knowledge, this is the first study to demonstrate the use of insulin as a fusion protein to improve the stability of easily degradable proteins. | Yu Mi Yuan Gao Daidi Fan Zhiguang Duan Rongzhan Fu Lihua Liang Wenjiao Xue Shanshan Wang | 2018 | Chinese Journal of Chemical Engineering2018，26，12： | 1 |
| 18 | GRB10 regulates β-cell mass by inhibiting β-cell proliferation and stimulating β-cell dedifferentiation显示文摘Decreased functional β-cell mass is the hallmark of diabetes, but the cause of this metabolic defect remains elusive. Here, we show that the levels of the growth factor receptor-bound protein 10(GRB10), a negative regulator of insulin and m TORC1 signaling, are markedly induced in islets of diabetic mice and high glucose-treated insulinoma cell line INS-1 cells. β-cell-specific knockout of Grb10 in mice increased β-cell mass and improved β-cell function. Grb10-deficient β-cells exhibit enhanced m TORC1 signaling and reduced β-cell dedifferentiation, which could be blocked by rapamycin. On the contrary, Grb10 overexpression induced β-cell dedifferentiation in MIN6 cells. Our study identifies GRB10 as a critical regulator of β-cell dedifferentiation and β-cell mass, which exerts its effect by inhibiting m TORC1 signaling. | Zixin Cai Fen Liu Yan Yang Dandan Li Shanbiao Hu Lei Song Shaojie Yu Ting Li Bilian Liu Hairong Luo Weiping Zhang Zhiguang Zhou Jingjing Zhang | 2022 | Journal of Genetics and Genomics2022，49，3： | 1 |

| 20 | Perilipin 2 and lipid droplets provide reciprocal stabilization显示文摘The lipid droplet (LD)-associated protein adipose differentiation-related protein (ADRP or PLIN2) is required for the formation and stability of the LD organelle, whereas its biological roles are still obscure. Herein, we show that PLIN2 is the most abundant protein on the lipid droplets (LDs) of mouse myoblast cell line C2C12. Both the expression of PLIN2 and the accumulation of LDs were up-regulated in a time- and dose-dependent manner when the cells were treated with oleate (OA). The protein level of PLIN2 was positively correlated with the formation of LDs, suggesting that LDs stabilize PLIN2. Furthermore, knocking out PLIN2 in C2C12 cells led to enlarged LDs and higher triacylglycerol hydrolysis activity. The isolated PLIN2 null LDs became closely contact w让h mitochondria and other cellular organelles. Additionally mitochondrial activity was suppressed by OA in PLIN2 null cells. Our results reveal the pivotal roles of PLIN2 in governing LD dynamics and their relationship to mitochondria, and suggest a reciprocal stabilization between PLIN2 and LDs. | Shimeng Xu Fei Zou Zhiqing Diao Shuyan Zhang Yaqin Deng Xiaotong Zhu Liujuan Cui Jinhai Yu Zhiguang Zhang Adekunle Toyin Bamigbade Hongchao Zhang Xuan Wei Xuelin Zhang Bin Liang Pingsheng Liu | 2019 | Biophysics Reports2019，5，3： | 1 |
