| 1 | Clinical characteristics of 24 asymptomatic infections with COVID-19 screened among close contacts in Nanjing,China显示文摘Previous studies have showed clinical characteristics of patients with the 2019 novel coronavirus disease(COVID-19)and the evidence of person-to-person transmission.Limited data are available for asymptomatic infections.This study aims to present the clinical characteristics of 24 cases with asymptomatic infection screened from close contacts and to show the transmission potential of asymptomatic COVID-19 virus carriers.Epidemiological investigations were conducted among all close contacts of COVID-19 patients(or suspected patients)in Nanjing,Jiangsu Province,China,from Jan 28 to Feb 9,2020,both in clinic and in community.Asymptomatic carriers were laboratory-confirmed positive for the COVID-19 virus by testing the nucleic acid of the pharyngeal swab samples.Their clinical records,laboratory assessments,and chest CT scans were reviewed.As a result,none of the 24 asymptomatic cases presented any obvious symptoms while nucleic acid screening.Five cases(20.8%)developed symptoms(fever,cough,fatigue,etc.)during hospitalization.Twelve(50.0%)cases showed typical CT images of ground-glass chest and 5(20.8%)presented stripe shadowing in the lungs.The remaining 7(29.2%)cases showed normal CT image and had no symptoms during hospitalization.These 7 cases were younger(median age:14.0 years;P=0.012)than the rest.None of the 24 cases developed severe COVID-19 pneumonia or died.The median communicable period,defined as the interval from the first day of positive nucleic acid tests to the first day of continuous negative tests,was 9.5 days(up to 21 days among the 24 asymptomatic cases).Through epidemiological investigation,we observed a typical asymptomatic transmission to the cohabiting family members,which even caused severe COVID-19 pneumonia.Overall,the asymptomatic carriers identified from close contacts were prone to be mildly ill during hospitalization.However,the communicable period could be up to three weeks and the communicated patients could develop severe illness.These results highlighted the importance of close contact tracing and longitudinally surveillance via virus nucleic acid tests.Further isolation recommendation and continuous nucleic acid tests may also be recommended to the patients discharged. | Zhiliang Hu Ci Song Chuanjun Xu Guangfu Jin Yaling Chen Xin Xu Hongxia Ma Wei Chen Yuan Lin Yishan Zheng Jianming Wang Zhibin Hu Yongxiang Yi Hongbing Shen | 2020 | Science China(Life Sciences)2020，63，5： | 77 |
| 2 | Trace metals in atmospheric fine particles in one industrial urban city: Spatial variations, sources, and health implications显示文摘Trace metals in PM2.5were measured at one industrial site and one urban site during September, 2010 in Ji'nan, eastern China. Individual aerosol particles and PM2.5samples were collected concurrently at both sites. Mass concentrations of eleven trace metals(i.e., Al, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Sr, Ba, and Pb) and one metalloid(i.e., As) were measured by inductively coupled plasma atomic emission spectroscopy(ICP-AES). The result shows that mass concentrations of PM2.5(130 μg/m3) and trace metals(4.03 μg/m3) at the industrial site were 1.3 times and 1.7 times higher than those at the urban site, respectively, indicating that industrial activities nearby the city can emit trace metals into the surrounding atmosphere. Fe concentrations were the highest among all the measured trace metals at both sites, with concentrations of 1.04 μg/m3at the urban site and 2.41 μg/m3at the industrial site, respectively. In addition, Pb showed the highest enrichment factors at both sites, suggesting the emissions from anthropogenic activities existed around the city. Correlation coefcient analysis and principal component analysis revealed that Cu, Fe, Mn, Pb, and Zn were originated from vehicular trafc and industrial emissions at both sites; As, Cr, and part of Pb from coal-fired power plant; Ba and Ti from natural soil. Based on the transmission electron microscopy analysis, we found that most of the trace metals were internally mixed with secondary sulfate/organic particles. These internally mixed trace metals in the urban air may have diferent toxic abilities compared with externally mixed trace metals. | Shengzhen Zhou Qi Yuan Weijun Li Yaling Lu Yangmei Zhang Wenxing Wang | 2014 | Journal of Environmental Sciences2014，26，1： | 23 |
| 3 | Lattice Boltzmann method and its applications in engineering thermophysics显示文摘The lattice Boltzmann method (LBM), a mesoscopic method between the molecular dynamics method and the conventional numerical methods, has been developed into a very efficient numerical alternative in the past two decades. Unlike conventional numerical methods, the kinetic theory based LBM simulates fluid flows by tracking the evolution of the particle distribution function, and then accumulates the distribution to obtain macroscopic averaged properties. In this article we review some work on LBM applications in engineering thermophysics: (1) brief introduction to the development of the LBM; (2) fundamental theory of LBM including the Boltzmann equation, Maxwell distribution function, Boltzmann-BGK equation, and the lattice Boltzmann-BGK equation; (3) lattice Boltzmann models for compressible flows and non-equilibrium gas flows, bounce back-specular-reflection boundary scheme for microscale gaseous flows, the mass modified outlet boundary scheme for fully developed flows, and an implicit-explicit finite-difference-based LBM; and (4) applications of the LBM to oscillating flow, compressible flow, porous media flow, non-equilibrium flow, and gas resonant oscillating flow. | HE YaLing LI Qing WANG Yong TANG GuiHua | 2009 | Chinese Science Bulletin2009，54，22： | 19 |
| 4 | The Expression and Location of Midkine in Gastric Carcinomas of Chinese Patients显示文摘Midkine (MK), a heparin-binding growth factor, can regulate cell growth, survival and differentiation. MK is expressed at high levels in a variety of human carcinomas. Recently, the urine and serum MK concentration was analyzed in gastric cancer patient. However, the association of the cytokine mRNA expression with the categorical clinicopathological variables of the tumors and the location of its protein expression in the tumor tissues are still elusive. MK mRNA expression from the surgically resected specimens of healthy gastric tissues (9 cases), gastric cancer tissues and the matched non-cancerous tissues adjacent to the cancer (37 cases) were assessed by reverse transcriptase-polymerase chain reaction (RT-PCR) and real-time PCR. Immunohistochemical analysis was performed to locate MK in gastric cancer. The expression of MK mRNA in gastric cancer was much higher in tumor tissues than that in the non-cancerous tissues and control tissue samples. And its expression was significantly associated with the pTNM stage and distant metastasis, but not with the differentiation grade, tumor size and nodal involvement. MK protein was ubiquitous in the tumor, especially in the adenoid part of tumors. In addition, it was found in the cytoplasm of tumor cells and highly concentrated in nucleus and nucleolus. The expression level and location of MK in gastric tumor tissues of Chinese Patients may be related to the tumor genesis and progression. Further study is necessary on the mechanism of MK in gastric tumorigenesis and tumor growth. | Yaling Huang Guochun Cao Hui Wang Qingling Wang Yayi Hou | 2007 | Cellular & Molecular Immunology2007，4，2： | 17 |
| 5 | A Review on Metal-Organic Framework-Derived Porous Carbon-Based Novel Microwave Absorption Materials显示文摘The development of microwave absorption materials(MAMs) is a considerable important topic because our living space is crowed with electromagnetic wave which threatens human’s health.And MAMs are also used in radar stealth for protecting the weapons from being detected.Many nanomaterials were studied as MAMs,but not all of them have the satisfactory performance.Recently,metal-organic frameworks(MOFs) have attracted tremendous attention owing to their tunable chemical structures,diverse properties,large specific surface area and uniform pore distribution.MOF can transform to porous carbon(PC) which is decorated with metal species at appropriate pyrolysis temperature.However,the loss mechanism of pure MOF-derived PC is often relatively simple.In order to further improve the MA performance,the MOFs coupled with other loss materials are a widely studied method.In this review,we summarize the theories of MA,the progress of different MOF-derived PC-based MAMs,tunable chemical structures incorporated with dielectric loss or magnetic loss materials.The different MA performance and mechanisms are discussed in detail.Finally,the shortcomings,challenges and perspectives of MOF-derived PC-based MAMs are also presented.We hope this review could provide a new insight to design and fabricate MOF-derived PC-based MAMs with better fundamental understanding and practical application. | Zhiwei Zhang Zhihao Cai Ziyuan Wang Yaling Peng Lun Xia Suping Ma Zhanzhao Yin Yi Huang | 2021 | Nano-Micro Letters2021，13，4： | 17 |
| 6 | Common dental diseases in children and malocclusion显示文摘Malocclusion is a worldwide dental problem that influences the affected individuals to varying degrees. Many factors contribute to the anomaly in dentition, including hereditary and environmental aspects. Dental caries, pulpal and periapical lesions, dental trauma, abnormality of development, and oral habits are most common dental diseases in children that strongly relate to malocclusion. Management of oral health in the early childhood stage is carried out in clinic work of pediatric dentistry to minimize the unwanted effect of these diseases on dentition. This article highlights these diseases and their impacts on malocclusion in sequence. Prevention, treatment, and management of these conditions are also illustrated in order to achieve successful oral health for children and adolescents, even for their adult stage. | Jing Zou Mingmei Meng Clarice S Law Yale Rao Xuedong Zhou | 2018 | International Journal of Oral Science2018，10，2： | 16 |
| 7 | Collagen-binding basic fibroblast growth factor improves functional remodeling of scarred endometrium in uterine infertile women: a pilot study显示文摘Intrauterine adhesion(IUA) is a common cause of uterine infertility and one of the most severe clinical features is endometrial fibrosis namely endometrial scarring for which there are few cures currently. Blocked angiogenesis is the main pathological change in the scarred endometrium. The fibroblast growth factor 2(b FGF), a member of FGF family, is usually applied to promote healing of refractory ulcer and contributes to angiogenesis of tissues. In this study, the sustained-release system of b FGF100 μg was administrated around scarred endometrium guiding by ultrasound every 4 weeks in 18 patients(2–4 times). Results showed that after treatment, the menstrual blood volume, endometrial thickness and the scarred endometrial area were improved.Histological study showed blood vessel density increased obviously. Three patients(3/18) achieved pregnancy over 20 gestational weeks. Therefore, administrating the b FGF surrounding scarred endometrium may provide a new therapeutic approach for the patients with endometrial fibrosis. | Peipei Jiang Xiaoqiu Tang Huiyan Wang Chenyan Dai Jing Su Hui Zhu Minmin Song Jingyu Liu Ziqing Nan Tong Ru Yaling Li Jingmei Wang Jun Yang Bing Chen Jianwu Dai Yali Hu | 2019 | Science China(Life Sciences)2019，62，12： | 16 |

| 9 | A design method and numerical study for a new type parabolic trough solar collector with uniform solar flux distribution显示文摘The non-uniform concentrated solar flux distribution on the outer surface of the absorber tube can lead to large circumferential temperature difference and high local temperature of the absorber tube wall,which is one of the primary causes of parabolic trough solar receiver(PTR)failures.In this paper,a secondary reflector used as a homogenizing reflector(HR)in a conventional parabolic trough solar collector(PTSC)was recommended to homogenize the solar flux distribution and thus increase the reliability of the PTR.The design method of this new type PTSC with a HR was also proposed.Meanwhile,the concentrated solar flux distribution was calculated by adopting the Monte Carlo ray-trace(MCRT)method.Then,the coupled heat transfer process within the PTR was simulated by treating the solar flux calculated by the MCRT method as the heat flux boundary condition for the finite volume method model.The solar flux distribution on the outer surface of the absorber tube,the temperature field of the absorber tube wall,and the collector efficiency were analyzed in detail.It was revealed that the absorber tube could almost be heated uniformly in the PTSC with a HR.As a result,the circumferential temperature difference and the maximum temperature could be reduced significantly,while the efficiency tended to decrease slightly due to the inevitably increased optical loss.Under the conditions studied in this paper,although the collector efficiency decreased by about 4%,the circumferential temperature difference was reduced from about 25 to 3 K and the maximum temperature was reduced from667 to 661 K. | WANG Kun HE YaLing CHENG ZeDong | 2014 | Science China(Technological Sciences)2014，57，3： | 15 |
| 10 | Advances in the Pathogenesis of Alzheimer’s Disease:Focusing on Tau-Mediated Neurodegeneration显示文摘In addition to senile plaques and cerebral amyloid angiopathy,the hyperphosphorylation of tau protein and formation of intraneuronal neurofibrillary tangles(NFTs)represents another neuropathological hallmark in AD brain.Tau is a microtubule-associated protein and localizes predominantly in the axons of neurons with the primary function in maintaining microtubules stability.When the balance between tau phosphorylation and dephosphorylation is changed in favor of the former,tau is hyperphosphorylated and the level of the free tau fractions elevated.The hyperphosphorylation of tau protein and formation of NFTs represent a characteristic neuropathological feature in AD brain.We have discussed the role of Aβin AD in our previous review,this review focused on the recent advances in tau-mediated AD pathology,mainly including tau hyperphosphorylation,propagation of tau pathology and the relationship between tau and Aβ. | Yale Duan Suzhen Dong Feng Gu Yinghe Hu Zheng Zhao | 2012 | Translational Neurodegeneration2012，1，1： | 15 |

| 12 | Notch signaling pathway:architecture,disease,and therapeutics显示文摘The NOTCH gene was identified approximately 110 years ago.Classical studies have revealed that NOTCH signaling is an evolutionarily conserved pathway.NOTCH receptors undergo three cleavages and translocate into the nucleus to regulate the transcription of target genes.NOTCH signaling deeply participates in the development and homeostasis of multiple tissues and organs,the aberration of which results in cancerous and noncancerous diseases.However,recent studies indicate that the outcomes of NOTCH signaling are changeable and highly dependent on context.In terms of cancers,NOTCH signaling can both promote and inhibit tumor development in various types of cancer.The overall performance of NOTCH-targeted therapies in clinical trials has failed to meet expectations.Additionally,NOTCH mutation has been proposed as a predictive biomarker for immune checkpoint blockade therapy in many cancers.Collectively,the NOTCH pathway needs to be integrally assessed with new perspectives to inspire discoveries and applications.In this review,we focus on both classical and the latest findings related to NOTCH signaling to illustrate the history,architecture,regulatory mechanisms,contributions to physiological development,related diseases,and therapeutic applications of the NOTCH pathway.The contributions of NOTCH signaling to the tumor immune microenvironment and cancer immunotherapy are also highlighted.We hope this review will help not only beginners but also experts to systematically and thoroughly understand the NOTCH signaling pathway. | Binghan Zhou Wanling Lin Yaling Long Yunkai Yang Huan Zhang Kongming Wu Qian Chu | 2022 | Signal Transduction and Targeted Therapy2022，7，4： | 14 |

| 15 | 2018 update of expert consensus statement on antiplatelet therapy in East Asian patients with ACS or undergoing PCI显示文摘East Asians are the most populous race in the world and their health status is an important global issue.Compared with Caucasian populations, East Asian patients have a different benefit/risk ratio when using antithrombotic treatment. Despite this observation, treatment strategies in East Asian patients are mostly based on the American and European guidelines. Despite a lower platelet inhibitory response to clopidogrel, East Asian patients show a similar or even a lower rate of ischemic event occurrence and higher bleeding risk compared with Caucasian patients. For potent P2Y_(12) inhibitors(ticagrelor and prasugrel),East Asian patients have shown less favorable net clinical benefits compared with Caucasian patients,which may be related to differences in pharmacokinetic/pharmacodynamic profiles and therapeutic zone of antiplatelet effect. This updated consensus mainly focuses on state-of-the-art and current controversies in the East Asian population. In addition, when East Asian patients are administered potent P2Y_(12) receptor inhibitors, the strategies and ongoing trials to overcome the related hurdles are discussed. | Yong Huo Young-Hoon Jeong Yanjun Gong Daowen Wang Ben He Jiyan Chen Guosheng Fu Yundai Chen Jianping Li Yi Li Shinya Goto Udaya S.Tantry Paul A.Gurbel Jong-Hwa Ahn Hyo-Soo Kim Myung Ho Jeong Yaling Han Sidney C.Smith Jr. Junbo Ge | 2019 | Science Bulletin2019，64，3： | 12 |
| 16 | Insight into the mode of action of 2,4-dichlorophenoxyacetic acid(2,4-D) as an herbicide显示文摘2,4-Dichlorophenoxyacetic acid(2,4-D)was thefirst synthetic herbicide to be commercially developed and has commonly been used as a broadleaf herbicide for over60 years.It is a selective herbicide that kills dicots without affecting monocots and mimics natural auxin at the molecular level.Physiological responses of dicots sensitive to auxinic herbicides include abnormal growth,senescence,and plant death.The identification of auxin receptors,auxin transport carriers,transcription factors response to auxin,and cross-talk among phytohormones have shed light on the molecular action mode of 2,4-D as a herbicide.Here,the molecular action mode of 2,4-D is highlighted according to the latestfindings,emphasizing the physiological process,perception,and signal transduction under herbicide treatment. | Yaling Song | 2014 | Journal of Integrative Plant Biology2014，56，2： | 12 |
| 17 | An entransy dissipation-based optimization principle for solar power tower plants显示文摘The entransy theory,which can be used to optimize the heat transfer network of a solar power tower system(SPTS)and improve its energy efficiency,was introduced in this paper.Firstly,the irreversibility of the heat transfer processes in a SPTS was analyzed and the total entransy dissipation equation of a SPTS was derived.Then,two types of optimization problems(reducing the total circulating flow rate or the total heat-exchanging area)of a SPTS were solved with conditional extremum model based on the formulas of total entransy dissipation.Finally,the entransy dissipation-based optimization principle was applied to a simple SPTS without re-heater and a complex SPTS with a re-heater.The results showed that under the chosen calculation conditions the minimum total thermal conductance was 19306.03 W K?1 for a SPTS without re-heater when the total heat capacity rate of heat transfer fluid(HTF)was 3200 W K?1.The minimum total thermal conductance was about 7.9%lower than the value predicted based on the typical outlet temperature of a receiver.This meant that the total heat exchange area or initial investment could be effectively reduced under the prescribed total HTF circulating flow rate.We also studied the variation trends of the two optimized results including minimum total HTF heat capacity rate and minimum total thermal conductance.The minimum total HTF heat capacity rate decreased with the given total thermal conductance,the minimum total thermal conductance decreased first and then increased with the given total HTF heat capacity rate.We also found that for a SPTS with a re-heater,the mixing temperature and the mixing position of HTF had significant effects on the two types of optimization problems. | ZHENG ZhangJing HE YaLing LI YinShi | 2014 | Science China(Technological Sciences)2014，57，4： | 11 |
| 18 | Suppression or knockout of SaF/SaM overcomes the Sa-mediated hybrid male sterility in rice显示文摘Hybrids between the indica and japonica subspecies of rice(Oryza sativa) are usually sterile, which hinders utilization of heterosis in the inter-subspecific hybrid breeding. The complex locus Sa comprises two adjacently located genes, SaF and SaM, which interact to cause abortion of pollen grains carrying the japonica allele in japonica-indica hybrids. Here we showed that silencing of SaF or SaM by RNA interference restored male fertility in indica-japonica hybrids with heterozygous Sa. We further used clustered regularly interspaced short palindromic repeats(CRISPR)/Cas9-based genome editing to knockout the SaF and SaM alleles, respectively, of an indica rice line to create hybrid-compatible lines. The resultant artificial neutral alleles did not affect pollen viability and other agricultural traits, but did break down the reproductive barrier in the hybrids. We found that some rice lines have natural neutral allele Sa-n, which was compatible with the typical japonica or indica Sa alleles in hybrids. Our results demonstrate that SaF and SaM are required for hybrid male sterility, but are not essential for pollen development. This study provides effective approaches for the generation of hybrid-compatible lines by knocking out the Sa locus or using the natural Sa-n allele to overcome hybrid male sterility in rice breeding. | Yongyao Xie Baixiao Niu Yunming Long Gousi Li Jintao Tang Yaling Zhang Ding Ren Yao-Guang Liu Letian Chen | 2017 | Journal of Integrative Plant Biology2017，59，9： | 11 |
| 19 | Characterization and allergic role of IL-33-induced neutrophil polarization显示文摘Neutrophils are involved in the pathogenesis of allergy.However,the contribution of the different functionally polarized neutrophils in allergy needs to be clarified.We sought to define the characteristics of interleukin(IL)-33-induced neutrophils and the involvement of this subset of polarized neutrophils in allergic pathogenesis.Freshly isolated neutrophils were treated with different cytokines and the cytokine expression levels were detected by realtime PCR.The gene expression profile of IL-33-induced neutrophils was determined by microarray assay.Adoptive transfer assay was used to investigate the function of IL-33-induced neutrophils in an ovalbumin(OVA)-induced allergic asthma model.IL-33-treated neutrophils selectively produced IL-4,IL-5,IL-9 and IL-13(referred as to N(IL-33)cells)and displayed a distinctive gene expression profile in sharp contrast to resting and lipopolysaccharide(LPS)-treated neutrophils.IL-33-induced neutrophils expressed high Levels of IL-1R2 on cell surface,whereas resting and LPS-treated neutrophils did not,indicating IL-1R2 might be used as a biomarker for N(IL-33)cells.Importantly,N(IL-33)neutrophils exist in the lungs of OVA-induced allergic asthma mice.Adoptive transfer of N(IL-33)neutrophils significantly promotes the severity of the lung pathogenesis in this model.IL-33 induces neutrophil polarization through c-Jun N-terminal kinase-and nuclear factor-κB-dependent pathways.A previously unappreciated neutrophil polarization driven by IL-33 with unique cell surface markers and cytokine/chemokineproducing gene profile was defined.The newly identified N(IL-33)subpopulation may have significant contribution to IL-33-related pathogenesis. | Bo Sun Linnan Zhu Yaling Tao Hai-Xi Sun Yang Li Peng Wang Yuzhu Hou Yang Zhao Xiaodong Zhang Lianfeng Zhang Ning Na Yong Zhao | 2018 | Cellular & Molecular Immunology2018，15，8： | 9 |
