| 1 | Spatial and temporal variations of forest LAI in China during 2000-2010显示文摘Forests are crucial terrestrial ecosystems.Their leaf area index (LAI) is a key parameter determining the exchange of matter and energy between the atmosphere and the ground surface.In this study,MOD 09A1 and MCD 43A1 data were input into an inversion model based on the 4-scale geometric optical model to retrieve 8-d 500 m LAI products in China during the period 2000 to 2010.The resulting LAI product was validated using LAI measured in 6 typical areas.The spatial and temporal variations of forest LAI and its relationships with temperature and precipitation were analyzed.The results show that the accuracy of the 500 m LAI product was above 70% in the 6 typical areas,indicating the reliability of this product.From 2000 to 2010,forest LAI in northeast,north,and south central China showed increasing trends.However,forest LAI in southeast and parts of southwest China showed downward trends,mainly because of the significant decrease observed during the period 2008 to 2010.Annual mean forest LAI positively correlated with annual mean temperature (AMT) in northeastern China and negatively correlated with AMT in southwest China.It had positive correlations with annual total precipitation in central south and north China.The abnormal climate conditions in 2001 and 2009 caused forest LAI to be obviously lower than normal in regions south of the Qinling Mountains and Huaihe River.Annual mean LAI decreased by more than 1.0 in some areas. | LIU YiBo JU WeiMin CHEN JingMing ZHU GaoLong XING BaiLing ZHU JingFang HE MingZhu | 2012 | Chinese Science Bulletin2012，57，22： | 22 |
| 2 | Multicenter study of the clinicopathological features and recurrence risk prediction model of early-stage breast cancer with low-positive human epidermal growth factor receptor 2 expression in China (Chinese Society of Breast Surgery 021)显示文摘Background:Breast cancer with low-positive human epidermal growth factor receptor 2(HER2)expression has triggered further refinement of evaluation criteria for HER2 expression.We studied the clinicopathological features of early-stage breast cancer with low-positive HER2 expression in China and analyzed prognostic factors.Methods:Clinical and pathological data and prognostic information of patients with early-stage breast cancer with low-positive HER2 expression treated by the member units of the Chinese Society of Breast Surgery and Chinese Society of Surgery of Chinese Medical Association,from January 2015 to December 2016 were collected.The prognostic factors of these patients were analyzed.Results:Twenty-nine hospitals provided valid cases.From 2015 to 2016,a total of 25,096 cases of early-stage breast cancer were treated,7642(30.5%)of which had low-positive HER2 expression and were included in the study.After ineligible cases were excluded,6486 patients were included in the study.The median follow-up time was 57 months(4-76 months).The disease-free survival rate was 92.1%at 5 years,and the overall survival rate was 97.4%at 5 years.At the follow-up,506(7.8%)cases of metastasis and 167(2.6%)deaths were noted.Multivariate Cox regression analysis showed that tumor stage,lymphvascular invasion,and the Ki67 index were related to recurrence and metastasis(P<0.05).The recurrence risk prediction model was established using a machine learning model and showed that the area under the receiving operator characteristic curve was 0.815(95%confidence interval:0.750-0.880).Conclusions:Early-stage breast cancer patients with low-positive HER2 expression account for 30.5%of all patients.Tumor stage,lymphvascular invasion,and the Ki67 index are factors affecting prognosis.The recurrence prediction model for breast cancer with low-positive HER2 expression based on a machine learning model had a good clinical reference value for predicting the recurrence risk at 5 years.Trial registration:ChiCTR.org.cn,ChiCTR2100046766. | Ling Xin Qian Wu Chongming Zhan Hongyan Qin Hongyu Xiang Ling Xu Jingming Ye Xuening Duan Yinhua Liu Chinese Society of Breast Surgery(CSBrS) Chinese Society of Surgery of Chinese Medical Association | 2022 | Chinese Medical Journal2022，，6： | 9 |
| 3 | A retrospective prognostic evaluation analysis using the 8th edition of American Joint Committee on Cancer(AJCC)cancer staging system for luminal A breast cancer显示文摘Objective: We retrospectively analyzed the clinical prognostic value of the 8th edition of the American Joint Committee on Cancer(AJCC) staging system for luminal A breast cancer.Methods: Using both the anatomic and prognostic staging in the 8th edition of AJCC cancer staging system, we restaged patients with luminal A breast cancer treated at the Breast Disease Center, Peking University First Hospital from 2008 to 2014. Follow-up data including 5-year disease free survival(DFS), overall survival(OS) and other clinic-pathological data were collected to analyze the differences between the two staging subgroups.Results: This study included 421 patients with luminal A breast cancer(median follow-up, 61 months). The 5-year DFS and OS rates were 98.3% and 99.3%, respectively. Significant differences in 5-year DFS but not OS were observed between different anatomic disease stages. Significant differences were observed in both 5-year DFS and OS between different prognostic stages. Application of the prognostic staging system resulted in assignment of 175 of 421 patients(41.6%) to a different group compared to their original anatomic stages. In total, 102 of 103 patients with anatomic stage IIA changed to prognostic stage IB, and 24 of 52 patients with anatomic stage IIB changed to prognostic stage IB, while 1 changed to prognostic stage IIIB. Twenty-two of 33 patients with anatomic stage IIIA were down-staged to IIA when staged by prognostic staging system, and the other 11 patients were down-staged to IIB. Two patients with anatomic stage IIIB were down-staged to IIIA. Among seven patients with anatomic stage IIIC cancer, two were down-staged to IIIA and four were down-staged to stage IIIB.Conclusions: The 8th edition of AJCC prognostic staging system is an important supplement to the breast cancer staging system. More clinical trials are needed to prove its ability to guide selection of proper systemic therapy and predict prognosis of breast cancer. | jingming ye wenjun wang ling xu xuening duan yuanjia cheng ling xin hong zhang shuang zhang ting li yinhua liu | 2017 | Chinese Journal of Cancer Research2017，29，4： | 8 |
| 4 | A transient bulk flow model with circular whirl motion for rotordynamic coefficients of annular seals显示文摘Bulk flow model with perturbation simplification has been used to calculate rotordynamic coefficients in annular seals which have significant influences on the dynamic behavior of rotors in turbomachinery. In this work, a transient bulk flow model with arbitrary rotor motion is developed, and the boundary conditions and friction factor in the model are calibrated with steady Computational Fluid Dynamics(CFD) analysis. The numerical solution scheme is developed based on the finite element method to obtain the transient reaction force in the seal clearance. With a periodic circular rotor orbit, the transient forces at multiple whirling frequencies are used to evaluate the rotordynamic coefficients. The leakage flowrate of CFD analysis has good agreement with experimental results and the calibrated parameters in bulk flow model are dependent on operating conditions. Although CFD calibration improves the accuracy of the perturbed bulk flow model, the direct damping is overestimated and the cross-coupled damping is underestimated. Compared with the perturbed model, the predictions of the transient bulk flow model are more agreeable with the experiment. | Peng XIA Zhansheng LIU Xiangyu YU Jingming ZHAO | 2018 | Chinese Journal of Aeronautics2018，31，5： | 7 |
| 5 | A novel STING agonist-adjuvanted pan-sarbecovirus vaccine elicits potent and durable neutralizing antibody and T cell responses in mice,rabbits and NHPs显示文摘The emergence of SARS-CoV-2 variants and potentially other highly pathogenic sarbecoviruses in the future highlights the need for pan-sarbecovirus vaccines.Here,we discovered a new STING agonist,CF501,and found that CF501-adjuvanted RBD-FC vaccine(CF501/RBD-FC)elicited significantly stronger neutralizing antibody(nAb)and T cell responses than Alum-and cGAMP-adjuvanted RBD-FC in mice.Vaccination of rabbits and rhesus macaques(nonhuman primates,NHPs)with CF501/RBD-FC elicited exceptionally potent nAb responses against SARS-CoV-2 and its nine variants and 41 S-mutants,SARS-CoV and bat SARSr-CoVs.CF501/RBD-FC-immunized hACE2-transgenic mice were almost completely protected against SARS-CoV-2 challenge,even 6 months after the initial immunization.NHPs immunized with a single dose of CF501/RBD-FC produced high titers of nAbs.The immunized macaques also exhibited durable humoral and cellular immune responses and showed remarkably reduced viral load in the upper and lower airways upon SARS-CoV-2 challenge even at 108 days post the final immunization.Thus,CF501/RBD-Fc can be further developed as a novel pan-sarbecovirus vaccine to combat current and future outbreaks of sarbecovirus diseases. | Zezhong Liu Jie Zhou Wei Xu Wei Deng Yanqun Wang Meiyu Wang Qian Wang Ming Hsieh Jingming Dong Xinling Wang Weijin Huang Lixiao Xing Miaoling He Chunlin Tao Youhua Xie Yilong Zhang Youchun Wang Jincun Zhao Zhenghong Yuan Chuan Qin Shibo Jiang Lu Lu | 2022 | Cell Research2022，32，3： | 5 |

| 7 | Wigner-Ville distribution and cross Wigner-Ville distribution of noisy signals显示文摘The Wigner-Ville distribution (WVD) and the cross Wigner-Ville distribution (XWVD) have been shown to be effcient in the estimation of instantaneous frequency (IF). But the statistical result of the IF estimation from XWVD peak is much better than using WVD peak. The reason is given from a statistical point of view. Theoretical studies show that XWVD of the analyzed signal can be estimated from XWVD of the noise-contaminated signal. The estimation is unbiased, and the variance is equal to that of noise. In this case, WVD cannot be estimated from WVD of the noise-contaminated signal. Therefore, higher SNR is required when WVD is used to analyze signals. | Chen Guanghua Ma Shiwei Liu Ming Zhu Jingming Zeng Weimin | 2008 | Journal of Systems Engineering and Electronics2008，19，5： | 4 |
| 8 | Cold Stress-induced Glucosyltransferase CsUGT78A15 is Involved in the Formation of Eugenol Glucoside in Camellia sinensis显示文摘Eugenol is a natural phenolic compound known for its health-promoting properties and its ability to add a floral scent to tea plants.Plant eugenol glycosides have been identified and shown to make important contributions to fruit floral quality.However,the details of their biosynthesis and metabolism in tea plants are still unknown.Here,eugenol glucoside was unambiguously identified as a native metabolite in the tea plant,and its biosynthesis was shown to be induced by low temperature treatment.Through the analysis of UGTs induced by low temperature,the glycosyltransferase CsUGT78A15 was identified in tea,and its encoded protein was shown to catalyze the glucosylation of eugenol.Vmax/Km ratios showed that eugenol was the most suitable substrate for CsUGT78A15.Sugar donor preference analysis showed that CsUGT78A15 had a higher selectivity for glucose,followed by galactose and glucuronic acid.The expression of CsUGT78A15was correlatedwith the accumulation of eugenol glucoside in different tissues and genotypes of tea.Down-regulation of CsUGT78A15 led to a decreased eugenol glucoside content under cold stress,indicating that CsUGT78A15 plays an important role in the biosynthesis of eugenol glucoside under cold stress.The identification of eugenol glucoside in the tea plant and the discovery of a cold stress-induced eugenol glucosyltransferase in tea provide the foundation for the improvement of tea flavor under cold stress and the biotechnological production of eugenol glucoside. | Mingyue Zhao Binbin Cai Jieyang Jin Na Zhang Tingting Jing Jingming Wang Yuting Pan Zixiang Zhou Yifan Zhao Yingying Feng Feng Yu Mengting Zhang Yating Li Zhonghua Liu Chuankui Song | 2020 | Horticultural Plant Journal2020，6，6： | 4 |
| 9 | Gap-free genome assembly and comparative analysis reveal the evolution and anthocyanin accumulation mechanism of Rhodomyrtus tomentosa显示文摘Rhodomyrtus tomentosa is an important f leshy-fruited tree and a well-known medicinal plant of the Myrtaceae family that is widely cultivated in tropical and subtropical areas of the world.However,studies on the evolution and genomic breeding of R.tomentosa were hindered by the lack of a reference genome.Here,we presented a chromosome-level gap-free T2T genome assembly of R.tomentosa using PacBio and ONT long read sequencing.We assembled the genome with size of 470.35 Mb and contig N50 of∼43.80 Mb with 11 pseudochromosomes.A total of 33382 genes and 239.31 Mb of repetitive sequences were annotated in this genome.Phylogenetic analysis elucidated the independent evolution of R.tomentosa starting from 14.37MYA and shared a recent WGD event with other Myrtaceae species.We identified four major compounds of anthocyanins and their synthetic pathways in R.tomentosa.Comparative genomic and gene expression analysis suggested the coloring and high anthocyanin accumulation in R.tomentosa tends to be determined by the activation of anthocyanin synthesis pathway.The positive selection and up-regulation of MYB transcription factors were the implicit factors in this process.The copy number increase of downstream anthocyanin transport-related OMT and GST gene were also detected in R.tomentosa.Expression analysis and pathway identification enriched the importance of starch degradation,response to stimuli,effect of hormones,and cell wall metabolism during the f leshy fruit development in Myrtaceae.Our genome assembly provided a foundation for investigating the origins and differentiation of Myrtaceae species and accelerated the genetic improvement of R.tomentosa. | angping Li Shiqiang Xu Zitong Xiao Jingming Wang Yu Mei Haifei Hu Jingyu Li Jieying Liu Zhuangwei Hou Junliang Zhao Shaohai Yang Jihua Wang | 2023 | Horticulture Research2023，10，3： | 3 |
| 10 | Global vegetation change analysis based on MODIS data in recent twelve years显示文摘Vegetation cover change is critical for understanding impacts and responses of vegetation to climate change. A study found that vegetation in the regions between 45°N-70°N was increasing using normalized difference vegetation index( NDVI) from 1981 to 1991 ten years ago. The global vegetation growth has changed because of climate change in recent twelve years( 2001- 2012). After thorough analysis based on satellite data,it is found that it is evident that the global vegetation changed( NDVI) little,and it is increasing slightly in Northern hemisphere while it is decreasing slightly in Southern Hemisphere. For different latitudes,vegetation is increasing 0.17% every year from 60°N to 70 °N( R^2= 0.47,P > 0.013),while the vegetation is decreasing 0.11% every year from 10°N to 10° S( R^2= 0.54,P > 0.004). For different continents,the vegetation in South America is decreasing 0.16% every year( R^2= 0.78,P > 0.0001) and it is increasing 0.05% every year in Asia( R^2= 0.28,P > 0.072) and 0.25% every year in Oceania( R^2= 0.24,P > 0.1). The analysis of global vegetation in different seasons indicates that spatial distribution of global temperature and water vapor will affect the spatial distribution of vegetation,in turn,the spatial distribution of vegetation will also regulate the global temperature and water vapor spatial distribution at large scale. The growth and distribution of vegetation are mainly caused by the orbit of the celestial bodies,and a big data model based on gravitational-magmatic change with the solar or the galactic system as its center is proposed to be built for analyzing how the earth's orbit position in the solar and galaxy system affects spatial-temporal variations of global vegetation and temperature at large scale. These findings promise a holistic understanding of the global climate change and potential underlying mechanisms. | 毛克彪 Li Zhaoliang Chen Jingming Ma Ying Liu Guang Tan Xuelan Yang Kaixian | 2016 | High Technology Letters2016，22，4： | 2 |
| 11 | Magnetic resonance imaging for non-invasive clinical evaluation of normal and regenerated cartilage显示文摘With the development of tissue engineering and regenerative medicine,it is much desired to establish bioimaging techniques to monitor the real-time regeneration efficacy in vivo in a non-invasive way.Herein,we tried magnetic resonance imaging(MRI)to evaluate knee cartilage regeneration after implanting a biomaterial scaffold seeded with chondrocytes,namely,matrix-induced autologous chondrocyte implantation(MACI).After summary of the T2 mapping and the T1-related delayed gadolinium-enhanced MRI imaging of cartilage(dGEMRIC)in vitro and in vivo in the literature,these two MRI techniques were tried clinically.In this study,18 patients were followed up for 1 year.It was found that there was a significant difference between the regeneration site and the neighboring normal site(control),and the difference gradually diminished with regeneration time up to 1 year according to both the quantitative T1 and T2 MRI methods.We further established the correlation between the quantitative evaluation of MRI and the clinical Lysholm scores for the first time.Hence,the MRI technique was confirmed to be a feasible semiquantitative yet non-invasive way to evaluate the in vivo regeneration of knee articular cartilage. | Xian Xu Jingming Gao Shuyun Liu Liang Chen Min Chen Xiaoye Yu Ning Ma Jun Zhang Xiaobin Chen Lisen Zhong Lin Yu Liming Xu Quanyi Guo Jiandong Ding | 2021 | Regenerative Biomaterials2021，8，5： | 2 |
| 12 | Acetylcholinesterase inhibitors and antioxidants mining from marine fungi:bioassays,bioactivity coupled LC-MS/MS analyses and molecular networking显示文摘Marine fungi are potentially important resources for bioactive lead compounds for discovering new drugs for diseases such as Alzheimer's disease.In this paper,the combined bioassay model of acetylcholinesterase(AChE)inhibition,1,1-diphenyl-2-picrylhydrazyl(DPPH)free radical scavenging,and Artemi ci larval lethality was used to evaluate the activity and toxicity of 35 n narine fun gal strains from seas around China.Their bioactive constitue nfs were revealed by thin layer chromatography(TLC)autography,bioactivity coupled LC-MS/MS and Global Natural Products Social Molecular Networking(GNPS).The results show that the extracts of five strains exhibited higher AChE inhibition ratios than the positive control compound,'tacrine;for which the ratio was 89.8%at 200 pig/ml.Six strains displayed both AChE inhibition(inhibition ratios>20%at 200 pg/ml)and DPPH scavenging activity(scavenging ratios>30%at 200 pg/ml)together with low Artemia larval toxicity(lethal rates<12%).TLC autography showed that the fractioned extracts of four strains contained highly diverse and different bioactive constituents,includi ng strains Talaromyces sp.C2\-\,Aspergillus ter re us C23-3,Trichoderma harzianum DLEN2008005,and Penicillium corylophilum TBG1-17.From the most potent sample F-l 1-1-b(derived from Aspergillus tern us C23-3),five AChE inhibitors and seven antioxida nts were recognized as bioactive molecules by AChE coupled ultrafiltration followed by LC-MS/MS,and LC-MS/MS coupled with DPPH incubation.Furthermore,with the aid of GNPS,the AChE inhibitors were plausibly annotated as territrem analogues including territrems A-C/D,arisugacin A and an unknown compound 4,and the seven antioxidants were assigned as butyrolactone I.aspernolide E,a phenolic derivative and possibly unknown compounds 8-10 and 12. | Yingying Nie Wencong Yang Yayue Liu Jingming Yang Xiaoling Lei William HGerwick Yi Zhang | 2020 | Marine Life Science & Technology2020，2，4： | 2 |
| 13 | Biodegradation Kinetics for Pre-treatment of Klebsiella pneumoniae Waste with Autothermal Thermophilic Aerobic Digestion显示文摘Biodegradation parameters and kinetic characteristics for pre-treating waste strains of Klebsiella pneu-moniae were studied in laboratory scale with an insulated reactor by an innovative technique,autothermal thermo-philic aerobic digestion(ATAD) . Based on an Arrhenius-type equation,an empirical model was developed to corre-late the removal of total suspended solid(TSS) with the initial TSS concentration,influent reaction temperature,aeration rate and stirring rate. The reaction temperatures of the ATAD system could be raised from the ambient temperatures of 25 °C to a maximum temperature of 65 °C. The exponentials for the initial TSS concentration,aeration rate and stirring rate were 1.579,-0.8175 and-0.6549,respectively,and the apparent activation energy was 6.8774 kJ·mol-1. The correlation coefficient for the pre-exponential factor was 0.9223. The TSS removal effi-ciency predicted by the model was validated with an actual test,showing a maximum relative deviation of 10.79%. The new model has a good practicability. | LIU Jingming SUN Dongdong LIU Hui NIE Yingbin ZHU Zhirong | 2010 | Chinese Journal of Chemical Engineering2010，18，6： | 2 |
