| 2 | Clinical study using mesenchymal stem cells for the treatment of patients with severe COVID-19显示文摘The coronavirus disease 2019(COVID-19)caused by SARS-CoV-2 was identified in December 2019.The symptoms include fever,cough,dyspnea,early symptom of sputum,and acute respiratory distress syndrome(ARDS).Mesenchymal stem cell(MSC)therapy is the immediate treatment used for patients with severe cases of COVID-19.Herein,we describe two confirmed cases of COVID-19 in Wuhan to explore the role of MSC in the treatment of COVID-19.MSC transplantation increases the immune indicators(including CD4 and lymphocytes)and decreases the inflammation indicators(interleukin-6 and C-reactive protein).High-flow nasal cannula can be used as an initial support strategy for patients with ARDS.With MSC transplantation,the fracrion of inspired O2(Fi02)of the two patients gradually decreased while the oxygen saturation(Sa02)and partial pressure of oxygen(P02)improved.Additionally,the patients9 chest computed tomography showed that bilateral lung exudate lesions were adsorbed after MSC infusion.Results indicated that MSC transplantation provides clinical data on the treatment of COVID-19 and may serve as an alternative method for treating COVID-19,particularly in patients with ARDS. | Lingling Tang Yingan Jiang Mengfei Zhu Lijun Chen Xiaoyang Zhou Chenliang Zhou Peng Ye Xiaobei Chen Baohong Wang Zhenyu Xu Qiang Zhang Xiaowei Xu Hainv Gao Xiaojun Wu Dong Li Wanli Jiang Jingjing Qu Charlie Xiang Lanjuan Li | 2020 | Frontiers of Medicine2020，14，5： | 8 |
| 3 | Size,morphology,and composition of lunar samples returned by Chang'E-5 mission显示文摘This study focuses on the physical and chemical properties of surficial lunar regolith(LR)samples returned from the Moon by the Chang’E-5(CE-5)mission.Insights regarding the effect of a new sampling geological site on the surficial lunar sample CE5 C0400 were illustrated using nondestructive techniques such as laser diffractometry coupled with image analysis,X-ray computed tomography,and field emission scanning electron microscopy equipped with energy dispersive spectroscopy,and Xray diffraction combined with Rietveld refinement.From the characterization analyses,the CE-5 sampling site in the northeastern Oceanus Procellarum on the Moon yields a unique collection of relatively regular-shaped and fine basalt-dominated particles.The median grain size D_(50) is(55.24±0.96)μm,falling within the relatively low end of the range of the Apollo lunar returned samples.The coefficient of uniformity C_(u)of 15.1 and the coefficient of curvature C_(c)of 1.7 could classify CE5 C0400 to be well-graded.The minerals in CE5 C0400 comprise approximately 44.5%pyroxene,30.4%plagioclase,3.6%olivine,and6.0%ilmenite.There is a relatively low content of approximately 15.5%glass phase in the CE-5 lunar sample.From the results,we deduce that the CE-5 LR structure could have mainly resulted from micrometeoroid impacts to achieve such a high level of maturity. | Hui Zhang Xian Zhang Guang Zhang Keqi Dong Xiangjin Deng Xiaosong Gao Yaodong Yang Yuan Xiao Xiao Bai Kaixin Liang Yiwei Liu Wenbin Ma Shaofan Zhao Ce Zhang Xiaojing Zhang Jian Song Wei Yao Hong Chen Weihua Wang Zhigang Zou Mengfei Yang | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，2： | 4 |

| 5 | A leaf shape mutant provides insight into PINOID Serine/Threonine Kinase function in cucumber(Cucumis sativus L.)显示文摘Optimizing leaf shape is a major challenge in efforts to develop an ideal plant type. Cucumber leaf shapes are diverse;however, the molecular regulatory mechanisms underlying leaf shape formation are unknown. In this study, we obtained a round leaf mutant(rl) from an ethyl methanesulfonate-induced mutagenesis population. Genetic analysis revealed that a single recessive gene, rl, is responsible for this mutation. A modified Mut Map analysis combined linkage mapping identified a single nucleotide polymorphism within a candidate gene,Csa1 M537400, as the mutation underlying the trait.Csa1 M537400 encodes a PINOID kinase protein involved in auxin transport. Expression of Csa1 M537400 was significantly lower in the rl mutant than in wild type, and it displayed higher levels of IAA(indole-3-acetic acid) in several tissues. Treatment of wild-type plants with an auxin transport inhibitor induced the formation of round leaves,similar to those in the rl mutant. Altered expression patterns of several auxin-related genes in the rl mutant suggest that rl plays a key role in auxin biosynthesis,transport, and response in cucumber. These findings provide insight into the molecular mechanism underlying the regulation of auxin signaling pathways in cucumber,and will be valuable in the development of an ideal plant type. | Mengfei Song Feng Cheng Jing Wang Qingzhen Wei Wenyuan Fu Xiaqing Yu Ji Li Jinfeng Chen Qunfeng Lou | 2019 | Journal of Integrative Plant Biology2019，61，9： | 3 |
| 6 | Health-related quality of life among rural residents aged 45-69 years in Hua County, Henan Province, China: Results of ESECC Trial for esophageal cancer screening with endoscopy显示文摘Objective: There have been few population-based studies evaluating health related quality of life(HRQOL) in rural populations in China, and this study aimed to assess the current status of and risk factors for HRQOL in a general rural population in high risk region of esophageal cancer in China.Methods: From November 2015 to September 2016, 12,085 permanent residents aged 45–69 years from 257 villages in the Endoscopic Screening for Esophageal Cancer in China(ESECC) trial(Clinical Trials.gov:NCT01688908) randomly selected from Hua County, Henan Province, China were interviewed. The EQ-5 D-3 L,a generic measure of HRQOL, and a questionnaire were used to assess their HRQOL and potential risk factors.Results: Among all the participants, 30.62% of the participants reported problems in at least one EQ-5 D dimension. Pain/discomfort(25.52%) was the most frequently reported problem followed by anxiety/depression(7.97%), mobility(5.82%), usual activities(2.61%) and self-care(1%). These rural residents had a mean EQ-5 D index score of 0.948, and lower EQ-5 D index scores were associated with older age, female gender, lower levels of household annual per capita income, living alone, using shallow wells as main source of drinking water, exposure to family members smoking, testiness, unhealthy dietary habits, overweight or obesity, upper gastrointestinal cancer related symptoms and chronic diseases.Conclusions: Rural residents in China have a relatively low quality of life. Health promotion programs in this population should focus on the elderly, especially elderly women and the elderly living alone. Improving basic living circumstances and primary medical care services should be priorities. Results of this study will also serve as the basis for the cost-utility evaluation in our ESECC screening trial. | Hui Wang Yaqi Pan Chuanhai Guo Fenglei Li Ruiping Xu Mengfei Liu Zhen Liu Fangfang Liu Hong Cai Yang Ke Zhonghu He | 2018 | Chinese Journal of Cancer Research2018，30，2： | 3 |
| 7 | Influence of ocean tidal loading on InSAR offshore areas deformation monitoring显示文摘The ocean tide can cause the redistribution of the seawater mass,resulting in earth's surface deformation,namely ocean tidal loading(OTL).OTL vertical displacement may reach several centimeters,especially in coastal areas,so its effect in the field of high precision geodesy must be considered.This study concentrates on the influences of OTL on InSAR deformation measurements.We improve the osu.chinasea.2010 regional model and then compare the improved regional model with other regional models.It turns out that the improved regional model can achieve higher precision.Then we use it to replace the offshore part of the global model to generate the present model.We find that the displacement observed by the present model is 2-3 mm larger than that of other models on some sites.Finally,the present model is used to correct the deformation observed by InSAR of Shanghai and Los Angeles.A comparison between the displacements of IGS station with the corrected data shows that the OTL correction can improve the accuracy of InSAR deformation results by about 20%. | Mengfei Lei Qijie Wang Xiaoli Liu Bing Xu Hongqiang Zhang | 2017 | Geodesy and Geodynamics2017，8，1： | 3 |
| 8 | p190A inactivating mutations cause aberrant RhoA activation and promote malignant transformation via the Hippo-YAP pathway in endometrial cancer显示文摘The Rho family of GTPases is strictly regulated by a large family of GTPase-activating proteins(GAPs)that stimulate the relatively weak intrinsic GTP-hydrolyzing activity of Rho GTPases.p190A is a potent and widely expressed GAP that acts on RhoA GTPases.p190A is frequently mutated in endometrial cancer,but the contribution of p190A mutations to endometrial tumorigenesis remains unclear.Here we identified that p190A is an upstream regulator of the Hippo-YAP signaling pathway,which is a critical regulator of cell proliferation,apoptosis,and cell fate.p190A knockout in endometrial cancer cells promoted cell proliferation,migration,and epithelial–mesenchymal transition(EMT),which were partially dependent on YAP activation.Wild-type p190A,but not endometrial cancer-associated mutants,suppressed the nuclear localization,transcriptional activity,and malignant transformation function of YAP.Moreover,the nuclear localization of YAP was enhanced in p190A-mutated endometrial cancer.These findings reveal novel molecular mechanisms underlying Hippo-YAP pathway-driven endometrial tumorigenesis and elucidate the potential for therapy targeting the Hippo-YAP pathway in p190A-mutated endometrial cancer. | Xiaoli Wen Jing Wan Qizhi He Mengfei Wang Shuangdi Li Mei Jiang Zhen Qian Binya Liu Wen Lu Kai Wang Kun Gao Xiaoping Wan | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 3 |
| 9 | Spatial distribution characteristics of bacterial community structure and gene abundance in sediments of the Bohai Sea显示文摘This study investigated differences in the community structure and environmental responses of the bacterial community in sediments of the Bohai Sea.Illumina high-throughput sequencing technology and real-time PCR were used to assay the bacterial 16S rRNA genes in the surface sediments of 13 sampling stations in the Bohai Sea.The results showed that sediments at the majority of the 13 sampling stations were contaminated by heavy metal mercury.The main phyla of bacteria recorded included Proteobacteria(52.92%),Bacteroidetes(11.76%),Planctomycetes(7.39%),Acidobacteria(6.53%)and Chloroflexi(4.97%).The genus with the highest relative abundance was Desulfobulbus(4.99%),which was the dominant genus at most sampling stations,followed by Lutimonas and Halioglobus.The main factors influencing bacterial community structure were total organic carbon,followed by depth and total phosphorus.The content of lead,cadmium,chromium,copper and zinc had a consistent effect on community structure.Arsenic showed a negative correlation with bacterial community structure in most samples,while the impact of mercury on community structure was not significant.The bacterial community in sediment samples from the Bohai Sea was rich in diversity and displayed an increase in diversity from high to low latitudes.The data indicated that the Bohai Sea had abundant microbial resources and was rich in bacteria with the potential to metabolize many types of pollutants. | Quanrui Chen Jingfeng Fan Jie Su Hongxia Ming Zhihao Sun Mengfei Li Xiaohui Zhao Yantao Wang Yingxue Zhang Huizhen Zhang Yuan Jin Xiaowan Ma Bin Wang | 2020 | Acta Oceanologica Sinica2020，39，2： | 2 |
| 10 | Taking advantage of glass:capturing and retaining the helium gas on the moon显示文摘Helium-3(3He)is a noble gas that has critical applications in scientific research and promising application potential as clean fusion energy.It is thought that the lunar regolith contains large amounts of helium,but it is challenging to extract because most helium atoms are reserved in defects of crystals or as solid solutions.Here,we find large amounts of helium bubbles in the glassy surface layer of ilmenite particles that were brought back by the Chang’E-5 mission.The special disordered atomic packing structure of glasses should be the critical factor for capturing the noble helium gas.The reserves in bubbles do not require heating to high temperatures to be extracted.Mechanical methods at ambient temperatures can easily break the bubbles.Our results provide insights into the mechanism of helium gathering on the moon and offer guidance on future in situ extraction. | Ao Li Xiao Chen Lijian Song Guoxin Chen Wei Xu Juntao Huo Meng Gao Ming Li Lei Zhang Bingnan Yao Min Ji Yan Zhang Shaofan Zhao Wei Yao Yanhui Liu Jun-Qiang Wang Haiyang Bai Zhigang Zou Mengfei Yang Weihua Wang | 2022 | Materials Futures2022，1，3： | 2 |
| 11 | A Promising Anti-Cytokine-Storm Targeted Therapy for COVID-19:The Artificial-Liver Blood-Purification System显示文摘The coronavirus disease 2019(COVID-19)pan-epidemic,resulting from infection with the 2019 novel coronavirus(2019-nCoV),also known as severe acute respiratory syndrome-coronavirus-2(SARS-CoV-2),is currently the source of public health concern worldwide;however,treatment of this infection has been clinically challenging in many patients[1].Importantly,2019-nCoV is the third fatal coronavirus that has emerged in the past two decades,following SARS-CoV and the Middle East respiratory syndrome(MERS)-CoV[2].The numbers of confirmed cases of COVID-19 infection and related deaths are still rising.As of 9 March 2020. | Yimin Zhang Liang Yu LingLing Tang Mengfei Zhu Yanqi Jin Zhouhan Wang Lanjuan Li | 2021 | Engineering2021，7，1： | 2 |
| 12 | The partitioning behavior of trace elements in subduction zones:Advances and prospects显示文摘The partitioning behavior of trace elements is of key importance for understanding the geochemical process and material cycle mechanism in subduction zones.This paper focuses on the advances and prospects on the studies of trace element partitioning in subduction zones from the following four aspects.(1)The properties of fluids derived from subducting slabs and their ability in element transport.How slab-derived solute-rich fluids and supercritical fluids are formed and what the roles and key control factors of these fluids are in transferring of elements(especially the high field strength elements)from slab to wedge are discussed.We point out that the detailed investigations of supercritical fluids may provide a new perspective for the element migration mechanism,material cycle process,arc magma genesis and so on.(2)The behavior of transition elements during mantle wedge melting.The behavior of the first row transition elements(Sc,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn)in the mantle partial melting process is compatible or incompatible,depending on residual mineral assemblage and physicochemical conditions.The partitioning behavior of the elements such as Sc,Ti,Co,Ni and Zn whose valence states do not change in the melting process mainly depends on the residual mineral assemblage and temperature,whereas the partitioning behavior of the multivalent elements such as V and Fe is also the function of oxygen fugacity(fO_(2))in addition to mineral assemblage and temperature.Therefore,the partitioning behavior of transition elements has important applications in tracing lithologic inhomogeneity and fO_(2)of the mantle wedges.(3)The specificity of element partitioning behavior during arc magma evolution.Garnet has Dy/Yb partitioning behavior different from amphibole,and rutile has Nb/Ta partitioning behavior different from amphibole.Dy/Yb and Nb/Ta partitioning differences for these minerals enable to distinguish the specific evolution process of arc magmas.The Dy/Yb and Nb/Ta generally decrease with the increase of SiO_(2)in arc magmas,indicating that amphibole fractionation should be the most important during arc magma differentiation.(4)The behavior of sulfur and chalcophile elements and porphyry metallogeny.In subduction zones,the behavior of chalcophile elements such as Cu and Au is controlled by sulfide and fluid.Therefore,the stability of sulfide,the time at which the fluid exsolves from the melt relative to sulfide saturation,the fluid/sulfide mass ratio and fluid/melt Cu and Au partition coefficients in intermediate-felsic magma-H_(2)O systems are especially important in understanding Cu and Au enrichment in magma-hydrothermal processes.Intermediate-felsic magmas mainly originate from the differentiation of arc magmas at lower crustal reservoirs,and thus the fluid exsolution from the lower crustal reservoirs and the fluid/melt and fluid/sulfide partition coefficients of Cu and Au should be the keys to understanding quantitatively how Cu and Au are migrated from the deep crust to the shallow site of mineralization. | Xiaolin Xiong Xingcheng Liu Li Li Jintuan Wang Wei Chen Mengfei Ruan Ting Xu Zhongxing Sun Fangfang Huang Jianping Li&Lei Zhang | 2020 | Science China Earth Sciences2020，63，12： | 2 |
| 13 | U-Pb Isotope Geochronology of Syntectonic Granites from Hainan Island,South China:Constraints on Tectonic Evolution of the Eastern Paleo-Tethys Ocean显示文摘Since the recognition of the Indosinian orogeny in northern Vietnam,Triassic orogens have been widely identified around the western and southwestern boundaries of the South China block.The paleo-Tethys sutures stretch from west to southeast,from Jinshajiang-Ailaoshan via NE Vietnam to Hainan Island;these sutures exhibit and develop voluminous Permian-early Triassic magmatism and numerous high-strain shear zones.As ophiolites related to the paleo-Tethys are lacking on Hainan Island,the eastward extension of the Indosinian orogeny and subduction and closure time of the paleo-Tethys Ocean on Hainan Island remain controversial.Here,an integrated kinematic and geochronological study has been conducted on two shear zones,called the Xiaomei and Mangsan shear zones.U-Pb zircon dating yields an age of early Triassic(252-251 Myr)for Xiaomei syntectonic granites which formed in the same tectonic setting and presented the similar nanoparticles to the Indosinian granites from Ailaoshan ductile shear zone,including the strawberry-like and flower-like nanoparticles.The NE-trending Mangsan shear zone represented by the gneissic granites with middle Permian ages(264-262 Myr)formed in the same tectonic setting as the Wuzhi-shan granites that were proposed as I-type granites.These middle Permian gneissic granites with arc affinity may represent an arc setting related to the NW subduction of the paleo-Tethys.The analyses reveal that granites with late Triassic ages(235-232 Myr)in the Xiaomei shear zone have the characteristics of A-type granites.The late Triassic extensional events on Hainan Island may be related to the subduction of the paleo-Pacific Plate beneath the East Asian continent. | ZHOU Yang YAN Yi LIU Hailing CAI Jianxin ZHOU Mengfei ZHANG Xinchang WANG Yin SHEN Baoyun | 2020 | Journal of Ocean University of China2020，19，6： | 1 |

| 16 | Ni–Co bimetallic coordination effect for long lifetime rechargeable Zn–air battery显示文摘The development of bifunctional oxygen electrocatalysts with high efficiency, high stability, and low cost is of great significance to the industrialization of rechargeable Zn–air batteries. A widely accepted view is that the oxygen reduction reaction(ORR) and the oxygen evolution reaction(OER) follow different catalytic mechanisms, and accordingly they need different active sites for catalysis. Transition metal elements have admirable electronic acceptance ability for coordinating with reactants, and this can weaken the bond energy between reactants, thus promoting the ORR or OER reactions. Herein, the ORR and OER activities of different transition metal supported nitrogen-doped carbon nanotubes were systematically studied and compared. The optimal catalyst for synchronous ORR and OER was obtained by pyrolyzing melamine, cobalt nitrate, and nickel nitrate on carbon nanotubes, called cobalt–nickel supported nitrogenmixed carbon nanotubes(CoNi–NCNT), which were equipped with two types of high-performance active sites—the Co/Ni–N–C structure for the ORR and Co Ni alloy particles for the OER—simultaneously. Remarkably, the optimized Co Ni–NCNT exhibited a satisfactory bifunctional catalytic activity for both the ORR and OER. The value of the oxygen electrode activity parameter,△E, of CoNi–NCNT was 0.81 V, which surpasses that of catalysts Pt/C and Ir/C, and most of the non-precious metal-based bifunctional electrocatalysts reported in previous literatures. Furthermore, a specially assembled rechargeable Zn–air cell with Co Ni–NCNT loaded carbon paper as an air cathode was used to evaluate the practicability. As a result, a superior specific capacity of 744.3 mAh/gZn, a peak power density of 88 mW/cm2, and an excellent rechargeable cycling stability were observed, and these endow the Co Ni–NCNT with promising prospects for practical application. | Mengfei Qiao Ying Wang Thomas Wagberg Xamxikamar Mamat Xun Hu Guoan Zou Guangzhi Hu | 2020 | Journal of Energy Chemistry2020，29，8： | 1 |

| 19 | Thermoelectric enhancement of p-type Si_(80)Ge_(20) alloy via co-compositing of dual oxides:Respective regulation for power factor and thermal conductivity byβ-Ga_(2)O_(3) and SiO_(2) aerogel powders显示文摘Si-based thermoelectric(TE)materials are exhibiting remarkable perspectives in self-energized applications with their special advantages.However,the relatively high total thermal conductivity(κ)prevents their TE enhancement.Here,a strategy of co-compositing dual oxides was implemented for enhancing the TE properties of p-type Si_(80)Ge_(20) bulks.Composited Ga2O_(3) was demonstrated to enhance the power factor(PF)due to the crystallization-induced effect of produced Ga by decomposition on SiGe matrix.Associating with compositing SiO_(2) aerogel(a-SiO_(2))powder,not only introduced the fine amorphous inclusions and decreased the grain size of host matrix,but also various nano morphologies were formed,i.e.,nano inclusions,precipitations,twin boundaries(TBs),and faults.Combining with the eutectic Ge,hierarchical scattering centers impeded the phonon transport comprehensively(decreasing the phonon group velocity(a v)and relaxation time)for reducing the lattice-induced thermal conductivity(lκ).As a result,a minimumκof 2.38 W·m^(−1)·K^(−1) was achieved,which is significantly dropped by 32.6%in contrast with that of the pristine counterpart.Ultimately,a maximal dimensionless figure of merit(ZT)of 0.9 was achieved at 600℃,which is better than those of most corresponding oxide-composited Si-based bulks. | Huajun LAI Ying PENG Mengfei WANG Runze SHI Junliang CHEN Chengyan LIU Yifeng WANG Lei MIAO Haiqiao WEI | 2023 | Journal of Advanced Ceramics2023，12，2： | 1 |
