| 1 | The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women显示文摘Objective To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus(GDM). Methods A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation(WG). Logistic regression analysis was applied to explore the relationships of maternal body composition and dietary intake with the risk of GDM morbidity. Results Age, pre-pregnant body weight(BW), and body mass index(BMI) were associated with increased risk of GDM. Fat mass(FM), fat mass percentage(FMP), extracellular water(ECW), BMI, BW, energy, protein, fat, and carbohydrates at 21-24 WG were associated with an increased risk of GDM. In contrast, fat free mass(FFM), muscular mass(MM), and intracellular water(ICW) were associated with a decreased risk of GDM. Conclusion Maternal body composition and dietary intake during the second trimester of pregnancy were associated with the risk of GDM morbidity. | Xu Qing Gao Zhi Ying Li Li Ming Wang Lu Zhang Qian Teng Yue Zhao Xia Ge Sheng Jing Hong Jiang Yang Yong Tao Liu Xiao Jun Lyu Chun Jian Mao Lun Yu Xiao Ming Liu Ying Hua Kong Ai Jing Yang Xue Yan Liu Zhao Zhang Yong Wang Jin Zhang Xin Sheng Xue Chang Yong Lu Yan Ping | 2016 | Biomedical and Environmental Sciences2016，29，1： | 29 |

| 3 | Comprehensive metabolomics expands precision medicine for triple-negative breast cancer显示文摘Metabolic reprogramming is a hallmark of cancer.However,systematic characterizations of metabolites in triple-negative breast cancer(TNBC)are still lacking.Our study profiled the polar metabolome and lipidome in 330 TNBC samples and 149 paired normal breast tissues to construct a large metabolomic atlas of TNBC.Combining with previously established transcriptomic and genomic data of the same cohort,we conducted a comprehensive analysis linking TNBC metabolome to genomics.Our study classified TNBCs into three distinct metabolomic subgroups:C1,characterized by the enrichment of ceramides and fatty acids;C2,featured with the upregulation of metabolites related to oxidation reaction and glycosyl transfer;and C3,having the lowest level of metabolic dysregulation.Based on this newly developed metabolomic dataset,we refined previous TNBC transcriptomic subtypes and identified some crucial subtype-specific metabolites as potential therapeutic targets.The transcriptomic luminal androgen receptor(LAR)subtype overlapped with metabolomic C1 subtype.Experiments on patient-derived organoid and xenograft models indicate that targeting sphingosine-1-phosphate(S1P),an intermediate of the ceramide pathway,is a promising therapy for LAR tumors.Moreover,the transcriptomic basal-like immune-suppressed(BLIS)subtype contained two prognostic metabolomic subgroups(C2 and C3),which could be distinguished through machine-learning methods.We show that N-acetyl-aspartyl-glutamate is a crucial tumor-promoting metabolite and potential therapeutic target for high-risk BLIS tumors.Together,our study reveals the clinical significance of TNBC metabolomics,which can not only optimize the transcriptomic subtyping system,but also suggest novel therapeutic targets.This metabolomic dataset can serve as a useful public resource to promote precision treatment of TNBC. | Yi Xiao Ding Ma Yun-Song Yang Fan Yang Jia-Han Ding Yue Gong Lin Jiang Li-Ping Ge Song-Yang Wu Qiang Yu Qing Zhang François Bertucci Qiuzhuang Sun Xin Hu Da-Qiang Li Zhi-Ming Shao Yi-Zhou Jiang | 2022 | Cell Research2022，32，5： | 18 |
| 4 | Punicalagin ameliorates collagen-induced arthritis by downregulating M1 macrophage and pyroptosis via NF-κB signaling pathway显示文摘Rheumatoid arthritis(RA)is a chronic inflammatory disease that eventually leads to disability.Inflammatory cell infiltration,severe joint breaking and systemic bone loss are the main clinical symptoms.In this study,we established a collagen-induced arthritis(CIA)model and found a large number of M1 macrophages and pyroptosis,which are important sources of proinflammatory cytokines.Punicalagin(PUN)is an active substance extracted from pomegranate peel.We found that it inhibited joint inflammation,cartilage damage and systemic bone destruction in CIA mice.PUN effectively alleviated the high expression of inflammatory cytokines in synovial tissue in vivo.PUN treatment shifted macrophages from the M1 phenotype to the M2 phenotype after stimulation with lipopolysaccharide(LPS)and interferon(IFN)-γ.The expression of inducible nitric oxide synthase(i NOS)and other proinflammatory cytokines released by M1 macrophages was decreased in the PUN treatment group.However,simultaneously,the expression of markers of anti-inflammatory M2 macrophages,such as arginase(Arg)-1 and interleukin(IL)-10,was increased.In addition,PUN treatment attenuated pyroptosis by downregulating the expression of NLRP3 and caspase-1,thereby preventing inflammatory cell death resulting from the release of IL-1βand IL-18.Mechanistically,PUN inhibited the activation of receptor activators of the nuclear factor-κB(NF-κB)signaling pathway,which contributes to M1 polarization and pyroptosis of macrophages.We concluded that PUN ameliorated pathological inflammation by inhibiting M1 phenotype polarization and pyroptosis and has great potential as a therapeutic treatment for human RA. | Gaoran Ge Jiaxiang Bai Qing Wang Xiaolong Liang Huaqiang Tao Hao Chen Minggang Wei Junjie Niu Huilin Yang Yaozeng Xu Yuefeng Hao Yi Xue Dechun Geng | 2022 | Science China(Life Sciences)2022，65，3： | 14 |
| 5 | Impact of Traffic Emissions on Local Air Quality and the Potential Toxicity of Traffic-related Particulates in Beijing, China显示文摘Objective Air-borne particulates from different sources could have different physicochemical properties and inflammatory potentials. This study aims to characterize the chemical compositions and the toxicity of ambient particulate matter (PM) associated with traffic emissions. Methods The concentrations of trace elements, organic carbon (OC), elemental carbon (EC) and polycyclic aromatic hydrocarbons (PAHs) in PM 2.5 and PM 10 were measured in samples collected at sites in Beijing, China. Their toxic effects on the pulmonary system of rats were investigated. Biochemical parameters (LDH, T-AOC, TP) and inflammatory cytokine(IL-6, IL-1, TNF-α) levels were measured in the lungs of rats exposed to traffic-related PM. Oxidative damage was observed. PM samples were taken from a near road site and an off road site in summer time in 2006. Results The concentrations of the USEPA priority pollutant PAHs in both PM 10 and PM 2.5 were higher (299.658 and 348.412) at the near road site than those (237.728 and 268.472) at the off road site. The similar trend was observed for the concentrations of trace elements in PM. Compared to coarse particles (PM 10 ), fine particles (PM 2.5 ) have a greater adsorption capacity to enrich toxic elements than inhalable particles. Decrease in antioxidant capacity and an increase in the amount of lipid peroxidation products in rat lung tissues was observed. Conclusion The findings of the present study suggest that the differing inflammatory responses of PM collected from the two road sites might have been mediated by the differing physicochemical characteristics. | TIAN Lei ZHANG Wei LIN Zhi Qing ZHANG Hua Shan XI Zhu Ge CHEN Jian Hua WANG Wei | 2012 | Biomedical and Environmental Sciences2012，25，6： | 13 |
| 6 | Primary site and regional lymph nodeinvolvement are independent prognosticfactors for early?stage extranodal nasal?typenatural killer/T cell lymphoma显示文摘Background:Nasal-type extranodal natural killer/T-cell lymphoma(ENKTCL) originates primarily in the nasal cavity or extra-nasal sites within the upper aerodigestive tract.However,it is unclear whether the primary site can serve as an independent prognostic factor or whether the varying clinical outcomes observed with different primary sites can be attributed merely to their propensities of regional lymph node involvement.The aim of this study was to investigate the prognostic implications of the primary site and regional lymph node involvement in patients with early-stage nasal-type ENKTCL.Methods:To develop a nomogram,we reviewed the clinical data of 215 consecutively diagnosed patients with early-stage nasal-type ENKTCL who were treated in Sun Yat-sen University Cancer Center with chemotherapy and radiotherapy between 2000 and 2011.The predictive accuracy and discriminative ability of the nomogram were determined using a concordance index(C-index) and calibration curve.Results:The 5-year overall survival(OS) and progression-free survival(PFS) rates of patients with nasal ENKTCL were higher than those of patients with extra-nasal ENKTCL(OS:68.2%vs.46.0%,P = 0.030;PFS:53.4%vs.26.6%,P = 0.010).The 5-year OS and PFS rates of patients with Ann Arbor stage IE ENKTCL were higher than those of patients with Ann Arbor stage HE ENKTCL(OS:66.3%vs.59.2%,P = 0.003;PFS:51.4%vs.40.3%,P = 0.009).Multivariate analysis showed that age >60 years,ECOG performance status score >2,elevated lactate dehydrogenase(LDH) level,extranasal primary site,and regional lymph node involvement were significantly associated with lower 5-year OS rate;age >60 years,elevated LDH level,extra-nasal primary site,and regional lymph node involvement were significantly associated with lower 5-year PFS rate.The nomogram included the primary site and regional lymph node involvement based on multivariate analysis.The calibration curve showed good agreement between the predicted and actual 5-year OS and PFS rates,and the C-indexes of the nomogram for the OS and PFS rates were 0.697 and 0.634,respectively.Conclusions:The primary site and regional lymph node involvement are independent prognostic factors for earlystage ENKTCL treated with chemotherapy followed by definitive radiotherapy. | Shao‑Qing Niu Yong Yang Yi‑Yang Li Ge Wen Liang Wang Zhi‑Ming Li Han‑Yu Wang Lu‑Lu Zhang Yun‑Fei Xia Yu‑Jing Zhang | 2016 | Chinese Journal of Cancer2016，35，5： | 8 |

| 10 | Experiment and simulation on the pyrite removal from the recirculating load of pulverizer with a dilute phase gas-solid fluidized bed显示文摘In order to reduce the energy consumption and subsequent air pollution of coal-fired power station, based on the analysis to size and density distribution of particles from the recirculating load of the classifier of pulverizer, the separation experiment on sampling material from power plant with a dilute phase fluidized bed to remove pyrite and other minerals and numerical simulation on the separation process were done. The results show that the minimum fluidization velocity is 1.62 cm/s. Pyrite and other minerals in the material are separated. Ash of the upper and bottom layer material account for 33.34% and 73.42% respectively and sulfur content occupy 1.12% and 8.96% respectively. Scanning electron microscopy and spectroscopy tests show that sulfur in the bottom material exist in the form of pyrite. Numerical simulation on the flow field form of the dilute phase separation bed with gas-solid two phase and particle motion verifies the experimental results. | Wang Shuai He Yaqun He Jingfeng Ge Linhan Liu Qing | 2013 | International Journal of Mining Science and Technology2013，23，2： | 6 |
| 11 | Surface Acidity/Basicity and Catalytic Reactivity of CeO2/7-Al2O3 Catalysts for the Oxidative Dehydrogenation of Ethane with Carbon Dioxide to Ethylene显示文摘Dehydrogenation of ethane to ethylene in CO2 was investigated over CeO2/γ-Al2O3 catalysts at 700℃ in a conventional flow reactor operating at atmospheric pressure. XRD, BET and microcalorimetric adsorption techniques were used to characterize the structure and surface acidity/basicity of the CeO2/γ-Al2O3 catalysts. The results show that the surface acidity decreased while the surface basicity increased after the addition of CeO2 to γ-Al2O3. Accordingly, the activity of the hydrogenation reaction of CO2 increased, which might be responsible for the enhanced conversion in the dehydrogenation of ethane to ethylene. The highest ethane conversion obtained was about 15% for the 25%CeO2/γ-Al2O3. The selectivity to ethylene was high for all the CeO2, γ-Al2O3 and CeO2/γ-Al2O3 catalysts. | Xin Ge, Shenghua Hu, Qing Sun.

| 13 | Exploring Seasonal and Circadian Rhythms in Structural Traits of Field Maize from LiDAR Time Series显示文摘Plant growth rhythm in structural traits is important for better understanding plant response to the ever-changing environment.Terrestrial laser scanning(TLS)is a well-suited tool to study structural rhythm under field conditions.Recent studies have used TLS to describe the structural rhythm of trees,but no consistent patterns have been drawn.Meanwhile,whether TLS can capture structural rhythm in crops is unclear.Here,we aim to explore the seasonal and circadian rhythms in maize structural traits at both the plant and leaf levels from time-series TLS.The seasonal rhythm was studied using TLS data collected at four key growth periods,including jointing,bell-mouthed,heading,and maturity periods.Circadian rhythms were explored by using TLS data acquired around every 2 hours in a whole day under standard and cold stress conditions.Results showed that TLS can quantify the seasonal and circadian rhythm in structural traits at both plant and leaf levels.(1)Leaf inclination angle decreased significantly between the jointing stage and bell-mouthed stage.Leaf azimuth was stable after the jointing stage.(2)Some individual-level structural rhythms(e.g.,azimuth and projected leaf area/PLA)were consistent with leaf-level structural rhythms.(3)The circadian rhythms of some traits(e.g.,PLA)were not consistent under standard and cold stress conditions.(4)Environmental factors showed better correlations with leaf traits under cold stress than standard conditions.Temperature was the most important factor that significantly correlated with all leaf traits except leaf azimuth.This study highlights the potential of time-series TLS in studying outdoor agricultural chronobiology. | Shichao Jin Yanjun Su Yongguang Zhang Shilin Song Qing Li Zhonghua Liu Qin Ma Yan Ge LingLi Liu Yanfeng Ding Frédéric Baret Qinghua Guo | 2021 | Plant Phenomics2021，3，1： | 5 |
| 14 | Smoking and Its Relation to Metabolic Status among Chinese Adults: Analysis of a Nationwide Survey显示文摘Objective To update the estimated prevalence rates of smoking and examine major metabolic diseases associated with smoking status in Chinese adults. Methods Using a complex, multistage, probability sampling design, we recruited a nationally representative sample of 98,658 Chinese adults aged ≥18 years in 2010. Information on current, former, never, and passive smoking status was obtained using a standard questionnaire. All estimates were weighted to represent the overall Chinese adult population. Results The estimated proportion of current smokers was 28.3% for Chinese adults aged ≥18 years. The corresponding values of former and passive smokers were 5.1% and 21.4%, respectively. Additionally, former smokers were found to have a less favorable metabolic risk profile among all categories of smoking status in both men and women. The prevalence of metabolic diseases such as diabetes and hypertension also increased with a greater number of smoking pack-years in men. Conclusion The prevalences of current smoking and passive smoking remain high in Chinese adults. | DING Lin XU Yu WANG Li Min JIANG Yong ZHANG Mei LI Yi Chong LU Jie Li XU Min WANG Tian Ge LI Mian ZHAO Zhi Yun DAI Meng WANG Wei Qing ZHAO Wen Hua WANG Lin Hong BI Yu Fang NING Guang 无 | 2016 | Biomedical and Environmental Sciences2016，29，9： | 5 |

| 16 | Surface morphology and electronic structure in stoichiometric superconductor CaKFe_(4)As_(4) robed by scanning tunneling microscopy/spectroscopy显示文摘CaKFe_(4)As_(4) is a new-type superconductor with a relatively high transition temperature of 35 K among stoichiometric iron-based superconductors. Based on scanning tunneling microscopy/spectroscopy, the surface morphology and electronic structure of CaKFe_(4)As_(4) single crystal were systematically investigated. The cleaved CaKFe_(4)As_(4) showed various morphologies, such as atomically resolved 1×1, 1×2, and √2×√2 lattices. By analyzing the geometrical correlations of these morphologies, the 1×1 and 1×2 lattices were identified as the original and reconstructed As layers, respectively, whereas the √2×√2 lattice was distinguished as the reconstructed alkaline-earth-metal or alkali-metal layer. The superconducting energy gap of 7.3 me V and bosonic mode of 12.7 me V were resolved in the scanning tunneling spectra. In addition, the superconducting energy gaps measured on different terminations were identical and consistent with the values obtained by bulk-sensitive techniques, indicating that the electronic structures of CaKFe_(4)As_(4) were insensitive to the surface reconstructions. Our study clarifies the relationships between complex surface reconstructions and surface terminations and preliminarily presents that there is no obvious effect of surface reconstructions on electronic states. | Xiaodong Yu Zhongxu Wei Zhanyi Zhao Tao Xie Chang Liu Ge He Qihong Chen Lei Shan Huiqian Luo Qing Huan Jie Yuan Kui Jin | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，12： | 5 |
| 17 | Alterations of tumor-related genes do not exactly match the histopathological grade in gastric adenocarcinomas显示文摘AIM:To investigate the diverse characteristics of different pathological gradings of gastric adenocarcinoma (GA) using tumor-related genes.METHODS:GA tissues in different pathological gradings and normal tissues were subjected to tissue arrays.Expressions of 15 major tumor-related genes were detected by RNA in situ hybridization along with 3' terminal digoxin-labeled anti-sense single strandedoligonucleotide and locked nucleic acid modifying probe within the tissue array.The data obtained were processed by support vector machines by four different feature selection methods to discover the respective critical gene/gene subsets contributing to the GA activities of different pathological gradings.RESULTS:In comparison of poorly differentiated GA with normal tissues,tumor-related gene TP53 plays a key role,although other six tumor-related genes could also achieve the Area Under Curve (AUC) of the receiver operating characteristic independently by more than 80%.Comparing the well differentiated GA with normal tissues,we found that 11 tumor-related genes could independently obtain the AUC by more than 80%,but only the gene subsets,TP53,RB and PTEN,play a key role.Only the gene subsets,Bcl10,UVRAG,APC,Beclin1,NM23,PTEN and RB could distinguish between the poorly differentiated and well differentiated GA.None of a single gene could obtain a valid distinction.CONCLUSION:Different from the traditional point of view,the well differentiated cancer tissues have more alterations of important tumor-related genes than the poorly differentiated cancer tissues. | Guo-Yan Liu,Xiao-Hong Wu,Yi-Zhuo Lu,Chao Pan,Ping Yin,Hong-Feng Liao,Ji-Qin Su,Qing Ge,Qi Luo,Department of General Surgery,The Affiliated Zhongshan Hospital of Xiamen University,The Digestive Disease Research Institute of Xiamen University,Xiamen 361004,Fujian Province,China Guo-Yan Liu,Bin Xiong,Department of Oncology,The Affiliated Zhongnan Hospital of Wuhan University,Wuhan 430071,Hubei Province,China Kun-Hong Liu,Department of Data Mining,Software School of Xiamen University,Xiamen 361005,Fujian Province,China Yong Zhang,Yu-Zhi Wang,The Academy of Military Medical Sciences,Beijing 100850,China | 2010 | World Journal of Gastroenterology2010，16，9： | 4 |
| 18 | Resilient and Safe Platooning Control of Connected Automated Vehicles Against Intermittent Denial-of-Service Attacks显示文摘Connected automated vehicles(CAVs)serve as a promising enabler for future intelligent transportation systems because of their capabilities in improving traffic efficiency and driving safety,and reducing fuel consumption and vehicle emissions.A fundamental issue in CAVs is platooning control that empowers a convoy of CAVs to be cooperatively maneuvered with desired longitudinal spacings and identical velocities on roads.This paper addresses the issue of resilient and safe platooning control of CAVs subject to intermittent denial-of-service(DoS)attacks that disrupt vehicle-to-vehicle communications.First,a heterogeneous and uncertain vehicle longitudinal dynamic model is presented to accommodate a variety of uncertainties,including diverse vehicle masses and engine inertial delays,unknown and nonlinear resistance forces,and a dynamic platoon leader.Then,a resilient and safe distributed longitudinal platooning control law is constructed with an aim to preserve simultaneous individual vehicle stability,attack resilience,platoon safety and scalability.Furthermore,a numerically efficient offline design algorithm for determining the desired platoon control law is developed,under which the platoon resilience against DoS attacks can be maximized but the anticipated stability,safety and scalability requirements remain preserved.Finally,extensive numerical experiments are provided to substantiate the efficacy of the proposed platooning method. | Xiaohua Ge Qing-Long Han Qing Wu Xian-Ming Zhang | 2023 | IEEE/CAA Journal of Automatica Sinica2023，10，5： | 4 |
| 19 | PDCD5 regulates iNKT cell terminal maturation and iNKT1 fate decision显示文摘Invariant natural killer T1(iNKT1)cells are characterized by the preferential expression of T-box transcription factor T-bet(encoded by Tbx21)and the production of cytokine IFN-γ,but the relationship between the developmental process and iNKT1 lineage diversification in the thymus remains elusive.We report in the present study a crucial role of programmed cell death 5(PDCD5)in iNKT cell terminal maturation and iNKT1 fate determination.Mice with T cell-specific deletion of PDCD5 had decreased numbers of thymic and peripheral iNKT cells with a predominantly immature phenotype and defects in response toα-galactosylceramide.Loss of PDCD5 also selectively abolished the iNKT1 lineage by reducing T-bet expression in iNKT cells at an early thymic developmental stage(before CD44 upregulation).We further demonstrated that TOX2,one of the high mobility group proteins that was highly expressed in iNKT cells at stage 1 and could be stabilized by PDCD5,promoted the permissive histone H3K4me3 modification in the promoter region of Tbx21.These data indicate a pivotal and unique role of PDCD5/TOX2 in iNKT1 lineage determination.They also suggest that the fate of iNKT1 may be programmed at the developmental stage of iNKT cells in the thymus. | Ke Wang Xinwei Zhang Yifan Wang Gaowen Jin Mingyang Li Shusong Zhang Jie Hao Rong Jin Xiaojun Huang Hounan Wu Jun Zhang Yingyu Chen Qing Ge | 2019 | Cellular & Molecular Immunology2019，16，9： | 4 |
