| 2 | Clinical research linking Traditional Chinese Medicine constitution types with diseases:a literature review of 1639 observational studies显示文摘OBJECTIVE:To analyze clinical studies on correlations between Traditional Chinese Medicine(TCM)body constitution types and diseases published in the past 10 years,and to provide an evidence base to support the use of such correlations for health maintenance and disease prevention.METHODS:We searched five databases for the period April 2009 to December 2019:China National Knowledge Infrastructure Database,Wanfang Database,China Science and Technology Journal Database,PubMed and Embase.Three types of observational studies on correlation between constitution types and diseases were included:cross-sectional,case-control and cohort studies.Descriptive statistical methods were employed for data analysis.RESULTS:A total of 1639 clinical studies were identified:1452(88.59%)cross-sectional studies,115(7.02%)case-control studies and 72(4.39%)cohort studies covering 30 regions of China and five other countries(Malaysia,South Korea,Singapore,Thailand and France).The collection of studies comprised 19 disease categories and 333 different diseases.The 10 most commonly studied diseases were hypertension,diabetes,stroke,coronary atherosclerotic heart disease(CAHD),sleep disorders,neoplasm of the breast,dysmenorrhea,fatty liver disease,chronic viral hepatitis B and dyslipidemia.We found high distributions for each biased constitution type in different patient populations as follows:Qi-deficiency constitution in stroke,diabetes,chronic obstructive pulmonary disease,acquired immunodeficiency syndrome and hypertension;Yang-deficiency constitution in female infertility,osteoporosis,irritable bowel syndrome,gonarthrosis and dysmenorrhea;Yin-deficiency constitution in hypertension,diabetes,constipation,female climacteric states and osteoporosis;phlegm-dampness constitution in hypertension,stroke,fatty liver disease,diabetes and metabolic syndrome;damp-heat constitution in acne,chronic gastritis,chronic viral hepatitis B,human papillomavirus infection and hyperuricemia;blood-stasis constitution in CAHD,endometriosis and stroke;Qi-stagnation constitution in hyperplasia and neoplasms of the breast,insomnia,depression and thyroid nodules;and inherited-special constitution in asthma and allergic rhinitis.CONCLUSION:Eight biased TCM constitutions were closely related to specific diseases,and could be used to guide individualized prevention and treatment.More rigorously designed studies are recommended to further verify the constitution-disease relationship. | Liang Xue Wang Qi Jiang Zeqiang Li Zhuqing Zhang Mengxing Yang Peiying Wang Xin Wang Yanqiu Qin Yuehua Li Tianxing Zhang Tianyi Wang Yi Sun Jianxiang Li Yusi Luo Hui Li Lingru | 2020 | Journal of Traditional Chinese Medicine2020，40，4： | 29 |
| 3 | Spectral analysis and self-adjusting mechanism for oscillation phenomenon in hydrogen-oxygen continuously rotating detonation engine显示文摘The continuously rotating detonation engine(CRDE)is a new concept of engines for aircraft and spacecraft.Quasi-stable continuously rotating detonation(CRD)can be observed in an annular combustion chamber,but the sustaining,stabilizing and adjusting mechanisms are not yet clear.To learn more deeply into the CRDE,experimental studies have been carried out to investigate hydrogen-oxygen CRDE.Pressure histories are obtained during each shot,which show that stable CRD waves are generated in the combustor,when feeding pressures are higher than 0.5 MPa for fuel and oxidizer,respectively.Each shot can keep running as long as fresh gas feeding maintains.Close-up of the pressure history shows the repeatability of pressure peaks and indicates the detonation velocity in hydrogen–oxygen CRD,which proves the success of forming a stable CRD in the annular chamber.Spectrum of the pressure history matches the close-up analysis and confirms the CRD.It also shows multi-wave phenomenon and affirms the fact that in this case a single detonation wave is rotating in the annulus.Moreover,oscillation phenomenon is found in pressure peaks and a self-adjusting mechanism is proposed to explain the phenomenon. | Liu Yusi Wang Yuhui Li Yongsheng Li Yang Wang Jianping | 2015 | Chinese Journal of Aeronautics2015，28，3： | 14 |
| 4 | miR-23a/b regulates the balance between osteoblast and adipocyte differentiation in bone marrow mesenchymal stem cells显示文摘Age-related osteoporosis is associated with the reduced capacity of bone marrow mesenchymal stem cells(BMSCs) to differentiate into osteoblasts instead of adipocytes. However, the molecular mechanisms that decide the fate of BMSCs remain unclear. In our study, micro RNA-23 a, and micro RNA-23b(mi R-23a/b) were found to be markedly downregulated in BMSCs of aged mice and humans. The overexpression of mi R-23a/b in BMSCs promoted osteogenic differentiation, whereas the inhibition of mi R-23a/b increased adipogenic differentiation. Transmembrane protein 64(Tmem64), which has expression levels inversely related to those of mi R-23a/b in aged and young mice, was identified as a major target of mi R-23a/b during BMSC differentiation. In conclusion, our study suggests that mi R-23a/b has a critical role in the regulation of mesenchymal lineage differentiation through the suppression of Tmem64. | Qi Guo Yusi Chen Lijuan Guo Tiejian Jiang Zhangyuan Lin | 2016 | Bone Research2016，4，2： | 12 |
| 5 | From Endoplasmic Reticulum (ER) to Nucleus: EIN2 Bridges the Gap in Ethylene Signaling显示文摘The phytohormone ethylene plays essential roles in regulating plant growth and development.Understanding the mechanism of ethylene biosynthesis,signal transduction,and downstream responses is of great importance to frame the entire processes of plant growth.Genetic and biochemical approaches were applied in recent years to help establish an approximately linear ethylene signaling pathway.Ethylene gas molecules are perceived by a five-member endoplasmicreticulum (ER)-Iocalized receptor family,including ETR1,ETR2,ERS1,ERS2,and EIN4.In the presence of ethylene,the receptors relieve the suppression of downstream responses by deactivating negative regulator CTR1,a Raf-like protein kinase (Kieber et al.,1993),whose function as a MAPKKK in ethylene signaling is still under debate (Zhao and Guo,2011).Downstream of CTR1,the signal is transmitted via an essential positive regulator EIN2,and subsequently to transcription factors EIN3/EIL1 by protecting them from EBF1/2-mediated ubiquitin-proteasome degradation,thus reprogramming the transcriptional cascade in the nucleus (Zhao and Guo,2011). | Yusi Ji Hongwei Guo | 2013 | Molecular Plant2013，6，1： | 11 |
| 6 | Human ACE2-Functionalized Gold“Virus-Trap”Nanostructures for Accurate Capture of SARS-CoV-2 and Single-Virus SERS Detection显示文摘The current COVID-19 pandemic urges the extremely sensitive and prompt detection of SARS-CoV-2 virus.Here,we present a Human Angiotensin-converting-enzyme 2(ACE2)-functionalized gold“virus traps”nanostructure as an extremely sensitive SERS biosensor,to selectively capture and rapidly detect S-protein expressed coronavirus,such as the current SARS-CoV-2 in the contaminated water,down to the single-virus level.Such a SERS sensor features extraordinary 106-fold virus enrichment originating from high-affinity of ACE2 with S protein as well as“virus-traps”composed of oblique gold nanoneedles,and 109-fold enhancement of Raman signals originating from multi-component SERS effects.Furthermore,the identification standard of virus signals is established by machine-learning and identification techniques,resulting in an especially low detection limit of 80 copies mL^(−1) for the simulated contaminated water by SARS-CoV-2 virus with complex circumstance as short as 5 min,which is of great significance for achieving real-time monitoring and early warning of coronavirus.Moreover,here-developed method can be used to establish the identification standard for future unknown coronavirus,and immediately enable extremely sensitive and rapid detection of novel virus. | Yong Yang Yusi Peng Chenglong Lin Li Long Jingying Hu Jun He Hui Zeng Zhengren Huang Zhi-Yuan Li Masaki Tanemura Jianlin Shi John R.Lombardi Xiaoying Luo | 2021 | Nano-Micro Letters2021，13，7： | 6 |

| 8 | Geological significance of nickeliferous minerals in the Fule Pb–Zn deposit, Yunnan Province, China显示文摘The Fule Pb–Zn deposit is located in the Sichuan–Yunnan–Guizhou Province, and it is an important and giant low temperature metallogenic domain in China.In our research area, the Pb–Zn deposits are mainly hosted in the Permian Yangxin Formation and are composed of dolostone and limestone. The distance between the ore bodies and the Permian Emeishan basalt ranged from 50 to160 m. In this study, the nickel rich minerals, including vaesite, polydymite and millerite, were reported for the first time in the Fule deposit. These minerals occurred as xenomorphic mineral aggregate and were sporadically distributed in the sphalerite–galena–calcite vein, which is the main ore type in the deposit. Our study indicated that the paragenetic sequence of minerals in the Fule deposit is the following order: polydymite → vaesite→ millerite → sphalerite → galena → tetrahedrite(tennantite).The geological occurrence characteristics of those nickeliferous minerals suggested that the Permian Emeishan basalt is a possible barrier layer of Pb–Zn ore-forming fluid, and it is an important source for the Ni and part of the Cu in the deposit. The Sichuan–Yunnan–Guizhou Pb–Zn mineralization province is a world-class production base of Pb and Zn, in which the Permian Emeishan basalt and Pb–Zn deposits have uniformly spatial distribution, but the relationship of mineralization between them is still under debate. This report provides new evidence forunderstanding the relationship between Pb–Zn mineralization and Permian Emeishan basalt in the Sichuan–Yunnan–Guizhou Pb–Zn mineralization province. | Zhenli Li Lin Ye Yusi Hu Zhilong Huang | 2018 | Acta Geochimica2018，37，5： | 6 |
| 9 | Secondary organic aerosols in Jinan, an urban site in North China: Significant anthropogenic contributions to heavy pollution显示文摘Secondary organic aerosols(SOAs) are an important component of particulates, but whether biogenic SOAs(BSOAs) or anthropogenic SOAs(ASOAs) are the dominant contributors to haze pollution remains poorly characterized. In this study, particulate samples were collected from September 2014 to August 2015 at an urban site in Jinan, which is the capital of Shandong Province and a typical city in the North China Plain. The PM2.5 samples were analyzed for BSOA(isoprene(SOAI) and monoterpenes(SOAM)) and ASOA(aromatic(SOAA)) tracers. The concentrations of the SOAAtracer(1.1 ± 1.0 ng/m3) were lowest, and those of SOAItracers(41.8 ± 86.2 ng/m3) were highest, with the concentrations of SOAMtracers(19.4 ± 9.9 ng/m3) being intermediate. The SOAItracers were more abundant in the summer and less abundant in the winter. Both SOAIand SOAMincreased with increasing ozone level but decreased with increasing NOx level. Correlation analysis revealed a good correlation between 2,3-dihydroxy-4-oxopentanoic acid and levoglucosan levels in three seasons. These results suggested that biomass burning activities occurring in the NCP can enhance the emissions of aromatics and should be controlled, especially in the autumn and winter. SOA tracers were classified according to pollution degree, and the results showed that as pollution increases, the contributions of SOAAincrease. These results indicate that reducing anthropogenic emissions is necessary to prevent SOA pollution, especially during heavy pollution episodes. | Yusi Liu Xingru Li Guiqian Tang Lili Wang Bo Lv Xueqing Guo Yuesi Wang | 2019 | Journal of Environmental Sciences2019，31，6： | 6 |
| 10 | Ethylene-induced microtubule reorientation is essential for fast inhibition of root elongation in Arabidopsis显示文摘Microtubule reorientation is a long-standing observation that has been implicated in regulating the inhibitory effect of ethylene on axial elongation of plant cells. However, the signaling mechanism underlying ethylene-induced microtubule reorientation has remained elusive. Here, we reveal, by live confocal imaging and kinetic root elongation assays, that the time courses of ethylene-induced microtubule reorientation and root elongation inhibition are highly correlated, and that microtubule reorientation is required for the full responsiveness of root elongation to ethylene treatment. Our genetic analysis demonstrated that the effect of ethylene on microtubule orientation and root elongation is mainly transduced through the canonical linear ethylene signaling pathway. By using pharmacological and genetic analyses, we demonstrate further that the TIR1/AFBs-Aux/IAAs-ARFs auxin signaling pathway, but not the ABP1-ROP6-RIC1 auxin signaling branch, is essential for ethylene-induced microtubule reorientation and root elongation inhibition. Together, these findings offer evidence for the functional significance and elucidate the signaling mechanism for ethylene-induced microtubule reorientation in fast root elongation inhibition in Arabidopsis. | Yichuan Wang Yusi Ji Ying Fu Hongwei Guo | 2018 | Journal of Integrative Plant Biology2018，60，9： | 4 |

| 12 | Charge‑Transfer Resonance and Electromagnetic Enhancement Synergistically Enabling MXenes with Excellent SERS Sensitivity for SARS‑CoV‑2 S Protein Detection显示文摘The outbreak of coronavirus disease 2019 has seriously threatened human health.Rapidly and sensitively detecting SARSCoV-2 viruses can help control the spread of viruses.However,it is an arduous challenge to apply semiconductor-based substrates for virus SERS detection due to their poor sensitivity.Therefore,it is worthwhile to search novel semiconductor-based substrates with excellent SERS sensitivity.Herein we report,for the first time,Nb2C and Ta2C MXenes exhibit a remarkable SERS enhancement,which is synergistically enabled by the charge transfer resonance enhancement and electromagnetic enhancement.Their SERS sensitivity is optimized to 3.0×10^6 and 1.4×10^6 under the optimal resonance excitation wavelength of 532 nm.Additionally,remarkable SERS sensitivity endows Ta2C MXenes with capability to sensitively detect and accurately identify the SARS-CoV-2 spike protein.Moreover,its detection limit is as low as 5×10^−9 M,which is beneficial to achieve real-time monitoring and early warning of novel coronavirus.This research not only provides helpful theoretical guidance for exploring other novel SERS-active semiconductor-based materials but also provides a potential candidate for the practical applications of SERS technology. | Yusi Peng Chenglong Lin Li Long Tanemura Masaki Mao Tang Lili Yang Jianjun Liu Zhengren Huang Zhiyuan Li Xiaoying Luo John RLombardi Yong Yang | 2021 | Nano-Micro Letters2021，13，3： | 3 |
| 13 | Trace Elements in Sphalerite from the Dadongla Zn-Pb Deposit, Western Hunan-Eastern Guizhou Zn-Pb Metallogenic Belt, South China显示文摘The western Hunan-eastern Guizhou Zn-Pb metallogenic belt is one of the important Zn-Pb mineralization regions in China.The Dadongla deposit,located in the northeast of Guizhou Province,is one of the typical Zn-Pb deposits in the region and has estimated resources more than 12 million metric tons(Mt)with an average grade of 4.11 wt%Zn+Pb.Its orebodies are hosted in the lower Cambrian Aoxi Formation dolomite,occurring as bedded,para-bedded in shape,and in conformity with the wall rock.The ore mineral assemblage is simple,dominated by sphalerite with minor pyrite and galena,and the gangue minerals are composed of dolomite,calcite with minor bitumen and barite.In view of the lack of geological and geochemical researches,the genesis of Zn-Pb ore is still unclear.Laser ablation-inductively coupled plasma mass spectrometry(LA-ICPMS)spot and mapping analyses were used to obtain sphalerite trace element chemistry in the Dadongla Zn-Pb deposit in Guizhou,China,aiming to constrain its ore genesis.The results show that sphalerite is characterized by the enrichment of Cd,Fe,Ge and Hg,corresponding with that of typical MVT deposits.Four zones were identified in the sphalerite crystal from Dadongla from the center to margin according to the color bands.in which the zone in the center,representing the early ore-stage sphalerite,is characterized by enrichment of Cd relatively,while the zone forming at late ore-stage is enriched in Ge and Hg relatively.The finding was controlled by differential leached metals content in ore-forming fluid from its source rock.Notably,critical element Ge trends to be enriched at the late ore-stage and follows a substitution of 2 Zn^2+(?)Ge^4++□(vacancy).Moreover,the calculated ore-forming temperature ranges from 79.9℃to 177.6℃by the empirical formula,which is similar to that of typical Mississippi Valley-type(MVT)deposits.Compared with the features of trace elements in sphalerite from different types of deposits,together with the geology,the Dadongla deposit belongs to an MVT Zn-Pb deposit. | HU Yusi YE Lin WEI Chen LI Zhenli HUANG Zhilong WANG Haoyu | 2020 | Acta Geologica Sinica(English Edition)2020，94，6： | 3 |

| 15 | Room-Temperature Solution-Processed PbS Quantum Dot Solar Cells显示文摘Summary of main observation and conclusion Colloidal quantum dots(CQDs)are attractive absorber materials for highefficiency photovoltalcs be-cause of their facile solution processing,bandgap tunability due to quant um confinement effect,and multi-exciton generation.To date,all published performance records for PbS CQDs solar cells have been based on the conventional hot-injection synthesis method.This method usually requires rela-tively strict conditions such as high temperature and the utilty of expensive source material pyrophoric bis(trimethylsilyl)sulfide(TM5-S),limiting the potential for large-scale and low-cost synthesis of Pbs CQDs.Here we report a facile room-temperature synthetic method to produce high-quality Pbs CQDs through inexpensive ionic source materials including Pb NOl2 and Na:5 in the presence of triethanolamine(TEA)as the stabilizing ligand.The PbS CQDs were successfully prepared with an average particle size of about 5 nm.Solar cells based on the as-synthesized PbS CQDs show a preliminary power conversion fficiency of 1.82%.This room-temperature and low-cost synth esis of PbS CQDs will further benefit the development of solution-processed CQD solar cells. | Yubin Xue Shun-Chang Liu Xinsheng Liu Yusi Yang Yimin Zhang Ding-Jiang Xue Jin-Song Hu | 2020 | Chinese Journal of Chemistry2020，38，4： | 3 |

| 17 | High-order compact finite volume methods on unstructured grids with adaptive mesh refinement for solving inviscid and viscous flows显示文摘In the present paper, high-order finite volume schemes on unstructured grids developed in our previous papers are extended to solve three-dimensional inviscid and viscous flows. The highorder variational reconstruction technique in terms of compact stencil is improved to reduce local condition numbers. To further improve the efficiency of computation, the adaptive mesh refinement technique is implemented in the framework of high-order finite volume methods. Mesh refinement and coarsening criteria are chosen to be the indicators for certain flow structures. One important challenge of the adaptive mesh refinement technique on unstructured grids is the dynamic load balancing in parallel computation. To solve this problem, the open-source library p4 est based on the forest of octrees is adopted. Several two-and three-dimensional test cases are computed to verify the accuracy and robustness of the proposed numerical schemes. | Jianhua PAN Qian WANG Yusi ZHANG Yuxin REN | 2018 | Chinese Journal of Aeronautics2018，31，9： | 3 |
| 18 | Sustainable recycling of titanium from TiO_(2) in spent SCR denitration catalyst via molten salt electrolysis显示文摘Spent catalyst used for denitration by selective catalytic reduction(spent SCR denitration catalysts) is one of the important urban mines due to the high content of TiO_(2)(~85 wt%) and the massive accumulation amount(over 100,000 tons),therefore,value-added reutilization of titanium in spent SCR catalysts is considerably meaningful.In this paper,a novel method is proposed for converting the titanium oxide in spent SCR denitration catalysts to metallic titanium.Specifically,titanium dioxide(TiO_(2)) was firstly obtained from spent SCR denitration catalysts after removing the impurities by hydrometallurgy process.Then,TiO_(2) is converted to Ti_(2)CO by carbothermic reduction method,and Ti_(2)CO was further purified by oleic acid capture.Finally,by utilizing the as-prepared Ti_(2)CO as the consumable anode in the NaCl-KCl molten salt,high-purity metallic titanium was deposited at cathode,all confirming the feasibility for the conversion of low-grade TiO_(2) in the spent catalysts,from 60 wt% to high-purity metallic Ti(99.5 wt%), furthermore,the energy consumption of this process is 3950 kWh tonne-1 Ti,which is lower than that of most traditional titanium metallurgy methods.The method herein can provide new insights for the value-added recycling of titanium resources in urban mines. | Xuyang Bai Xiaojia Shang Heli Wan Yusi Che Bin Yang Jilin He Jianxun Song | 2021 | Journal of Energy Chemistry2021，30，7： | 3 |
| 19 | Enhance the delivery of light energy ultra-deep into turbid medium by controlling multiple scattering photons to travel in open channels显示文摘Multiple light scattering is considered as the major limitation for deep imaging and focusing in turbid media.In this paper,we present an innovative method to overcome this limitation and enhance the delivery of light energy ultradeep into turbid media with significant improvement in focusing.Our method is based on a wide-field reflection matrix optical coherence tomography(RM-OCT).The time-reversal decomposition of the RM is calibrated with the Tikhonov regularization parameter in order to get more accurate reversal results deep inside the scattering sample.We propose a concept named model energy matrix,which provides a direct mapping of light energy distribution inside the scattering sample.To the best of our knowledge,it is the first time that a method to measure and quantify the distribution of beam intensity inside a scattering sample is demonstrated.By employing the inversion of RM to find the matched wavefront and shaping with a phase-only spatial light modulator,we succeeded in both focusing a beam deep(~9.6 times of scattering mean free path,SMFP)inside the sample and increasing the delivery of light energy by an order of magnitude at an ultra-deep(~14.4 SMFP)position.This technique provides a powerful tool to understand the propagation of photon in a scattering medium and opens a new way to focus light inside biological tissues. | Jing Cao Qiang Yang Yusi Miao Yan Li Saijun Qiu Zhikai Zhu Pinghe Wang Zhongping Chen | 2022 | Light(Science & Applications)2022，11，5： | 2 |
| 20 | The silicothermic reduction of magnesium in flowing argon and numerical simulation of novel technology显示文摘The silicothermic reduction of magnesium was investigated by the non-isothermal thermoanalysis in flowing argon,while the traditional investigations of silicothermic process for magnesium reduction were carried out under vacuum conditions.Firstly,the thermal gravimetric(TG)and derivative thermogravimetric(DTG)characteristic of briquettes prepared with calcined dolomite,ferrosilicon and fluorite were characterized by the thermogravimetric analyzer(TGA)at different heating rates.The intrinsic chemical kinetic mechanism was identified as a formal chemical reaction with the Nth order type which showed apparent activation energy E and reaction order n were 290.168 kJ mol^(-1) and 1.076,respectively.Then,a novel technique of magnesium production without vacuum was put forward and a three-dimensional unsteady numerical model incorporating the chemical reaction,radiation,heat conduction and heat convection was established and simulated,which was verified by Pidgeon process and novel tech no logy.rIhe nu merical results showed that the cycle time of the novel technique could be reduced when the argon temperature was higher than 1343 K and the argon entrance velocity was over 0.05 m s^(-1).And the effect of the argon temperature on reduction degree was much larger than that of entrance velocity. | Yusi Che Chao Zhang Jianxun Song Xiaojia Shang Xiping Chen Jilin He | 2020 | Journal of Magnesium and Alloys2020，8，3： | 2 |
