2Establishment of apparent quantum yield and maximum ecosystem assimilation on Tibetan Plateau alpine meadow ecosystem显示文摘The alpine meadow is widely distributed on the Tibetan Plateau with an area of about 1.2×106kn2. Damxung County, located in the hinterland of the Tibetan Plateau, is the place covered with this typical vegetation. An open-path eddy covariance system was set up in Damxung rangeland station to measure the carbon flux of alpine meadow from July to October,2003. The continuous carbon flux data were used to analyze the relationship between net ecosystem carbon dioxide exchange (NEE) and photosynthetically active radiation (PAR), as well as the seasonal patterns of apparent quantum yield (α) and maximum ecosystem assimilation (Pmax).Results showed that the daytime NEE fitted fairly well with the PAR in a rectangular hyperbola function, with α declining in the order of peak growth period (0.0244 μmolCO2 · μmol-1pAR) >early growth period > seed maturing period > withering period (0.0098 μmolCO2 · μmol-1pAR).The Pmax did not change greatly during the first three periods, with an average of 0.433mgCO2· m-2· s-1, i.e. 9.829 μmolCO2· m-2· s-1. However, during the withering period, Pmax was only 0.35 mgCO2 · m-2 · s-1, i.e. 7.945 μmolCO2 · m-2 · s-1. Compared with other grassland ecosystems, the α of the Tibetan Plateau alpine meadow ecosystem was much lower.XU Lingling, ZHANG Xianzhou, SHI Peili & YU Guirui Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences, Beijing 100101, China Graduate School of the Chinese Acedemy of Sciences, Beijing 100039, China 2005Science China Earth Sciences2005,48,z1:23
3COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented.Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu 2021China CDC weekly2021,3,21:16
4Gene expression signatures for phlegm-dampness constitution of Chinese Medicine显示文摘Dear Editor,The term'individualized medicine'was first used in Biochemistry Individuality in 1956 by Williams(Williams et al.,1956).With the emergence of the post-genome era in the21st century,individualized precision medicine has attracted increasing attention.In traditional Chinese medicine(TCM),there is also concept of individualized medicine,which is known as the Chinese constitutional theory,proposed in the1970s(Wang,2012).According to this theory,theLingru Li Juan Feng Haiqiang Yao Lan Xie Yu Chen Lingling Yang Shujuan Hou Shipeng Zhao Ranran Sun Yanling Wu Tongtong Bai Yingshuai Li Ruoxi Yu Ji Wang Qi Wang 2017Science China(Life Sciences)2017,60,1:13

6Nitrogen Biological Cycle Characteristics of Seepweed(Suaeda salsa) Wetland in Intertidal Zone of Huanghe(Yellow) River Estuary显示文摘From April 2008 to November 2009,the nitrogen(N) cycle of plantsoil system in seepweed(Suaeda salsa) wetland in the intertidal zone of the Huanghe(Yellow) River estuary was studied.Results showed that soil N had sig-nificant seasonal fluctuations and vertical distribution,and the net N mineralization rates in topsoil were significantly different in growing season(p < 0.01).The N/P ratio(9.87 ± 1.23) of S.salsa was less than 14,indicating that plant growth was limited by N.The N accumulated in S.salsa litter at all times during decomposition,which was ascribed to the N immobilization by microbes from the environment.Soil organic N was the main N stock of plant-soil system,accounting for 97.35% of the total N stock.The N absorption and utilization coefficients of S.salsa were very low(0.0145 and 0.3844,respectively),while the N cycle coefficient was high(0.7108).The results of the N turnovers among compartments of S.salsa wetland showed that the N uptake amount of aboveground part and root were 7.764 g/m2and 4.332 g/m2,respectively.The N translocation amounts from aboveground part to root and from root to soil were 3.881 g/m2 and 0.626 g/m2,respectively.The N translocation amount from aboveground living body to litter was 3.883 g/m2,the annual N return amount from litter to soil was more than 0.125(-) g/m2(minus represented immobilization),and the net N mineralization amount in topsoil(0-15 cm) in growing season was 1.190 g/m2.The assessment of N biological cycle status of S.salsa wetland indicated that N was a very important limiting factor and the ecosystem was situated in unstable and vulnerable status.The S.salsa was seemingly well adapted to the low-nutrient status and vulnerable habitat,and the N quantitative relationships determined in the compartment model might provide scientific base for us to reveal the special adaptive strategy of S.salsa to the vulnerable habitat in the following studies.SUN Zhigao MOU Xiaojie SUN Jingkuan SONG Hongli YU Xiang WANG Lingling JIANG Huanhuan SUN Wanlong SUN Wenguang 2012Chinese Geographical Science2012,22,1:9

8Rapid reconstitution of NK1 cells after allogeneic transplantation is associated with a reduced incidence of graft-versus-host disease显示文摘The balance between immunostimulation and immunoregulation in T cell immunity is achieved by maintaining specific ratios of Th1, Th2, Th3 and Tr1 cells. Here, we investigate levels of type 1(IFN-gamma; NK1), type 2(IL-13; NK2), type 3(TGF-beta;NK3) and regulatory(IL-10; NKr) cytokines in peripheral blood to assess the cytokine profiles of natural killer(NK) cells following human allogeneic hematopoietic stem cell transplantation(allo-HSCT). NK2 and NK3 cell expansion was observed after allo-HSCT; levels of NKr cells reached donor levels at day 15, though levels of NK1 cells were consistently lower than donor levels until day 60 after allo-HSCT. Multivariate analysis showed that a higher level of NK1 cells by day 15 was associated with a lower overall risk of acute graft-versus-host disease(GVHD)(HR 0.157, P=0.010) as well as II-IV acute GVHD(HR0.260, P=0.059). Furthermore, higher levels of NK1 cells by day 15 were correlated with lower rates of cytomegalovirus(CMV)reactivation(HR 0.040, 0.005–0.348, P=0.003). These results indicate that rapid reconstitution of NK cells, especially NK1 cells,can help prevent the development of GVHD as well as CMV reactivation after allogeneic transplantation.Xingxing Yu Lingling Xu Yingjun Chang Xiaojun Huang Xiangyu Zhao 2018Science China(Life Sciences)2018,61,8:9
9Sequential fate-switches in stem-like cells drive the tumorigenic trajectory from human neural stem cells to malignant glioma显示文摘Glioblastoma(GBM)is an incurable and highly heterogeneous brain tumor,originating from human neural stem/progenitor cells(hNSCs/hNPCs)years ahead of diagnosis.Despite extensive efforts to characterize hNSCs and end-stage GBM at bulk and single-cell levels,the de novo gliomagenic path from hNSCs is largely unknown due to technical difficulties in early-stage sampling and preclinical modeling.Here,we established two highly penetrant hNSC-derived malignant glioma models,which resemble the histopathology and transcriptional heterogeneity of human GBM.Integrating time-series analyses of whole-exome sequencing,bulk and single-cell RNA-seq,we reconstructed gliomagenic trajectories,and identified a persistent NSC-like population at all stages of tumorigenesis.Through trajectory analyses and lineage tracing,we showed that tumor progression is primarily driven by multi-step transcriptional reprogramming and fate-switches in the NSC-like cells,which sequentially generate malignant heterogeneity and induce tumor phenotype transitions.We further uncovered stage-specific oncogenic cascades,and among the candidate genes we functionally validated C1QL1 as a new glioma-promoting factor.Importantly,the neurogenic-to-gliogenic switch in NSC-like cells marks an early stage characterized by a burst of oncogenic alterations,during which transient AP-1 inhibition is sufficient to inhibit gliomagenesis.Together,our results reveal previously undercharacterized molecular dynamics and fate choices driving de novo gliomagenesis from hNSCs,and provide a blueprint for potential early-stage treatment/diagnosis for GBM.Xiaofei Wang Ran Zhou Yanzhen Xiong Lingling Zhou Xiang Yan Manli Wang Fan Li Chuanxing Xie Yiming Zhang Zongyao Huang Chaoqiong Ding Kaidou Shi Weida Li Yu Liu Zhongwei Cao Zhen-Ning Zhang Shengtao Zhou Chong Chen Yan Zhang Lu Chen Yuan Wang 2021Cell Research2021,31,6:8
10Mechanism of acupuncture regulating visceral sensation and mobility显示文摘Chinese ancient medical scientists have long focused on the internal and external contacts between acupoints on the surface of the body and the viscera.The Miraculous Pivot(it is one of the earliest medical classics in China)stated,“Twelve regular channels belong to the zang-fu organs internally,and connect to the extremities and joints externally.”Traditional Chinese medicine considers acupoints as defined areas where the Qi of viscera and meridians are transfused.These include the reaction points of visceral diseases on the body surface as well as the acupuncture trigger points that promote the flow of Qi and blood,and regulate visceral function.Chinese ancient medical scientists classified the specificity of the main acupoints in the body based on the meridian doctrine,which has been instructing clinical application for about 2000 years.Laws on the domino effect of acupoints have mainly focused on conclusions to clinical experiences.Indications of some acupoints exceed the practical paradigm since the excessive extension occurred during theory derivation.The current research direction on acupuncture focuses on three aspects:the effectiveness of acupuncture and moxibustion;the relevances and associations between meridians and viscera;and the physical and chemical properties and relevant physical basis of acupoints.The relevance between meridians and viscera is the central theory in the meridian doctrine,and acupoints are regarded as an important link in the relationship between meridians and viscera.Specific relationships between acupoints and target organs exist.Stimulating different acupoints on the body surface can help deal with different diseases,especially visceral diseases.In addition,acupoints have a dual function of reflecting and treating visceral diseases.There is no systemic research available on acupoint specificity,despite current knowledge and clinical experiences,which results in a weak foundation for acupuncture theory.This study focuses on the relevance and associations between meridians and viscera.A summary of the mechanisms of acupuncture regulating visceral sensation and mobility and the specific relationships between acupoints and their target organs are presented in this review.Peijing Rong Bing Zhu Yuqing Li Xinyan Gao Hui Ben Yanhua Li Liang Li Wei He Rupeng Liu Lingling Yu 2011Frontiers of Medicine2011,5,2:8

12Rescue of premature aging defects in Cockayne syndrome stem cells by CRISPR/Cas9-mediated gene correction显示文摘Cockayne syndrome(CS)is a rare autosomal recessive inherited disorder characterized by a variety of clinical features,including increased sensitivity to sunlight,progressive neurological abnormalities,and the appearance of premature aging.However,the pathogenesis of CS remains unclear due to the limitations of current disease models.Here,we generate integration-free induced pluripotent stem cells(iPSCs)from fibroblasts from a CS patient bearing mutations in CSB/ERCC6 gene and further derive isogenic genecorrected CS-iPSCs(GC-iPSCs)using the CRISPR/Cas9 system.CS-associated phenotypic defects are recapitulated in CS-iPSC-derived mesenchymal stem cells(MSCs)and neural stem cells(NSCs),both of which display increased susceptibility to DNA damage stress.Premature aging defects in CS-MSCs are rescued by the targeted correction of mutant ERCC6.We next map the transcriptomic landscapes in CS-iPSCs and GC-iPSCs and their somatic stem cell derivatives(MSCs and NSCs)in the absence or presence of ultraviolet(UV)and replicative stresses,revealing that defects in DNA repair account for CS pathologies.Moreover,we generate autologous GC-MSCs free of pathogenic mutation under a cGMP(Current Good Manufacturing Practice)-compliant condition,which hold potential for use as improved biomaterials for future stem cell replacement therapy for CS.Collectively,our models demonstrate novel disease features and molecular mechanisms and lay a foundation for the development of novel therapeutic strategies to treat CS.Si Wang Zheying Min Qianzhao Ji Lingling Geng Yao Su Zunpeng Liu Huifang Hu Lixia Wang Weiqi Zhang Keiichiro Suzuiki Yu Huang Puyao Zhang Tie-Shan Tang Jing Qu Yang Yu Guang-Hui Liu Jie Qiao 2020Protein & Cell2020,11,1:7
13Spatiotemporal characterization and regional contributions of O3 and NO2:An investigation of two years of monitoring data in Henan,China显示文摘To investigate the characteristics of ground level ozone(O3)for Henan Province,the ambient air quality monitoring data of 2015 and 2016 were analyzed.The result showed that the 8 h-max-O3 concentrations displayed a distinct seasonality,where the maximum and minimum values,averaging 140.41,54.19μg/m3,occurred in summer and winter,respectively.There is a significant correlation between meteorological factors and O3 concentration.The Voronoi neighborhood averaging analysis indic ated that O3,temperature,and ultraviolet radiation in Henan province were decreased from northwest to southeast,while relative humidity and precipitation displayed the opposite trend.Besides meteorological factors,the chemical processes play an essential role in ozone formation.Reactions of NO,NO2 and O3 form a closed system,and the partitioning point of the OX-component(O3+NO2)was at 40 and 80μg/m3 for nitrogen oxide(NOx)in winter and summer,respectively,with NO2 dominating at higher NOx pollution and O3 being the m ajor component at lower levels.The relationship between oxidant(OX=O3+NO2)and NOx concentrations were evaluated to understand the regional and local contribution of OX.It showed that high regional contribution occurred in the spring,whereas the highest local contribution lead to the summer peak of O3 observed in Zhengzhou.This present study reveals important environment impacts from the photochemical process and the meteorological conditions in the region with better understanding on the O3 characterization.Shijie Yu Shasha Yin Ruiqin Zhang Lingling Wang Fangcheng Su Yixiang Zhang Jian Yang 2020Journal of Environmental Sciences2020,32,4:7
14Effect of borneol and electroacupuncture on the distribution of hyperforin in the rat brain显示文摘Hyperforin is an antidepressant drug that has unstable therapeutic effects,due to its poor ability to cross the blood-brain barrier.Borneol and electroacupuncture have both been found to increase the permeability of the blood-brain barrier.As such,the current study examined the distribution of hyperforin in the rat brain,and the effects on the brain distribution of hyperforin of borneol alone (orally administered),and borneol combined with electroacupuncture treatment.High-performance liquid chromatography technology and pharmacokinetic analysis revealed that treatment with borneol alone (300,600 mg/kg) increased peak concentration and the area under the curve for hyperforin in the brain.In addition,the bioavailability of hyperforin in rat brain increased by 42.7%.However,increasing the dose of borneol dose did not appear to increase the distribution of hyperforin in the brain.Importantly,applying electroacupuncture at Baihui (GV 20) or Yamen (GV 15) appeared to enhance the brain-delivery effects of borneol,although this effect was weak.Overall,our results indicated that borneol alone or combined with electroacupuncture can provide promising strategies for brain-targeted delivery in central nervous system therapy.Bin Yu Ming Ruan Yong Sun Xiaobing Cui Yun Yu Lingling Wang Taihui Fang 2011Neural Regeneration Research2011,6,24:6
15Effect of Jiawei Shenfu decoction on tumor necrosis factor-alpha and nuclear factor-kappa B in patients who have chronic heart failure with syndromes of deficiency of heart Yang显示文摘OBJECTIVE:To examine the clinical efficacy of Jiawei Shenfu decoction on tumor necrosis factor-alpha (TNF-cα) and nuclear factor-kappa B (NF-KB) levels in patients who have chronic heart failure with syndromes of deficiency of heart Yang.METHODS:A total of 63 patients with syndromes of deficiency of heart Yang (chronic heart failure)were enrolled.Patients were randomly divided into the control group and Jiawei Shenfu group.All patients received standard medications for treatment of chronic heart failure.Patients in the Jiawei Shenfu group were additionally provided Jiawei Shenfu decoction one dose daily.Treatments continued for 4 consecutive weeks.The primary endpoint was the change in plasma B-type natriuretic peptide (BNP),NF-KB,and TNF-cα levels during 4 weeks of treatment.RESULTS:At the 4-week follow-up,a significant reduction in BNP levels compared with baseline was observed in both groups,but the Jiawei Shenfu decoction group showed a significantly greater reduction than did the control group.The Jiawei Shenfu group also showed superior performance regarding the Minnesota Living with Heart Failure Questionnaire score,the Chinese medicine syndrome score,heart rate,left ventricular ejection fraction,and 6-min walking distance compared with the control group.The degree of changes in NF-KB and TNF-α levels in the Jiawei Shenfu group was more significant than that in the control group.CONCLUSION:Routine medicine combined with Jiawei Shenfu decoction for patients with heart Yang deficiency syndrome in chronic heart failure can improve the left ventricular ejection fraction and cardiac function,and reduce BNP levels.The mechanism may be related to inhibition of pro-inflammatory cytokines and the NF-KB-induced kinase pathway,leading to amelioration of the inflammatory response.Yu Mei Guo Hangyuan Ye Lingling Bian Jiaping Ma Lijuan Zheng Chunli 2019Journal of Traditional Chinese Medicine2019,39,3:6

18The Impact of Large-Scale Reclamation on Hydro-Dynamic Environment--A Case Study of Xinghua Bay显示文摘A hydro-dynamic model is established on basis of MIKE21 FM to simulate the hydro-dynamic characteristics of Xinghua Bay and investigate the influence of reclamation project on the tidal elevation and tidal currents. Tidal elevation data was obtained at the six tide gauge stations around the Xinghua Bay, and another six current stations were established to observe the tidal current velocity and direction. Validation shows that the model-simulated tidal elevation and tidal currents agree well with observations made at different stations. Predictions are made according to the reclamation project proposed in the regional marine planning of Hanjiang Industrial Park around the port in Putian City. The variations of hydro-dynamic factors, such as tide, current velocity and direction and tidal influx are obtained, and the adverse effect of reclamation on marine environment is discussed. It is shown that the tidal level inside the Xinghua Bay during high tide decreases after the reclamation project is completed. The tidal currents during flooding tide generally decrease in the southeast of the reclamation region, with the maximum decreasing amplitude reaching 0.44 m s^(-1). On the other hand, the tidal currents during flooding tide increase around the southeast and southwest corners of the reclamation region. The tidal currents during ebb tide increase around the southeast and southwest corners of the reclamation region, with the maximum increasing amplitude attaining 0.18 m s^(-1). The results in this paper can give some guidance for the marine environment management and the effective utilization of land in Putian.YU Jing BAO Xianwen DING Yang ZHANG Wei ZHOU Lingling 2016Journal of Ocean University of China2016,15,4:5
19Genome-wide identification and expression analysis of Gossypium RING-H2 finger E3 ligase genes revealed their roles in fiber development,and phytohormone and abiotic stress responses显示文摘Background: RING-H2 finger E3 ligase(RH2FE3) genes encode cysteine-rich proteins that mediate E3 ubiquitin ligase activity and degrade target substrates. The roles of these genes in plant responses to phytohormones and abiotic stresses are well documented in various species, but their roles in cotton fiber development are poorly understood. To date, genome-wide identification and expression analyses of Gossypium hirsutum RH2FE3 genes have not been reported.Methods: We performed computational identification, structural and phylogenetic analyses, chromosomal distribution analysis and estimated K_a/K_s values of G. hirsutum RH2FE3 genes. Orthologous and paralogous gene pairs were identified by all-versus-all BLASTP searches. We predicted cis-regulatory elements and analyzed microarray data sets to generate heatmaps at different development stages. Tissue-specific expression in cotton fiber, and hormonal and abiotic stress responses were determined by quantitative real time polymerase chain reaction(qRT-PCR) analysis.Results: We investigated 140 G. hirsutum, 80 G. arboreum, and 89 G. raimondi putative RH2FE3 genes and their evolutionary mechanisms and compared them with orthologs in Arabidopsis and rice. A domain-based analysis of the G.hirsutum RH2FE3 genes predicted conserved signature motifs and gene structures. Chromosomal localization showed the genes were distributed across al G. hirsutum chromosomes, and 60 duplication events(4 tandem and 56 segmental duplications) and 98 orthologs were detected. cis-elements were detected in the promoter regions of G. hirsutum RH2FE3 genes. Microarray data and qR T-PCR analyses showed that G. hirsutum RH2FE3 genes were strongly correlated with cotton fiber development. Additional y, almost al the identified genes were up-regulated in response to phytohormones(brassinolide, gibberel ic acid(GA), indole-3-acetic acid(IAA), and salicylic acid(SA)) and abiotic stresses(cold, heat,drought, and salt).Conclusions: The genome-wide identification, comprehensive analysis, and characterization of conserved domains and gene structures, as wel as phylogenetic analysis, cis-element prediction, and expression profile analysis of G. hirsutum RH2FE3 genes and their roles in cotton fiber development and responses to plant hormones and abiotic stresses are reported here for the first time. Our findings wil contribute to the genome-wide analysis of putative RH2FE3 genes in other species and lay a foundation for future physiological and functional research on G. hirsutum RH2FE3 genes.QANMBER Ghulam YU Daoqian LI Jie WANG Lingling MA Shuya LU Lili YANG Zuoren LI Fuguang 2018Journal of Cotton Research2018,1,1:5
20The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2.
