1Organochlorine compounds and polycyclic aromatic hydrocarbons in surface sediment from Baiyangdian Lake,North China:Concentrations,sources profiles and potential risk显示文摘Organochlorine pesticides(OCPs),polychlorinated biphenyls(PCBs),and polycyclic aromatic hydrocarbons(PAHs) were determined in nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river(Fuhe River) in North China.Total concentrations of OCPs,PCBs and PAHs in sediments ranged from 5.4 to 707.6 ng/g,2.3 to 197.8 ng/g,and 101.3 to 6360.5 ng/g,respectively.The levels of contaminants in Fuhe River were significantly higher than those in Baiyandian Lake.For hexachlorocyclohexane(HCHs) and dichlorodiphenytrichloroethanes(DDTs),α-HCH and p,p-DDT were predominant isomers;while for PCBs,PCB 28/31,PCB 40/103,PCB 60,PCB 101,and PCB 118 were predominant congeners.Possible sources derived from historical usage for OCPs and incomplete combustion fuel,wood,and coal and exhaustion of boats or cars for PAHs.Risk assessment of sediment indicated that sediments in Fuhe River were likely to pose potential biological adverse impact.Guocheng Hu Xiaojun Luo Fengchao Li Jiayin Dai Jianyang Guo Shejun Chen Cao Hong Bixian Mai Muqi Xu 2010Journal of Environmental Sciences2010,22,2:42
2Long-Term Effects of Manure and Inorganic Fertilizers on Yield and Soil Fertility for a Winter Wheat-Maize System in Jiangsu, China显示文摘Winter wheat-maize rotations are dominant cropping systems on the North China Plain, where recently the use of organic manure with grain crops has almost disappeared. This could reduce soil fertility and crop productivity in the long run. A 20-year field experiment was conducted to 1) assess the effect of inorganic and organic nutrient sources on yield and yield trends of both winter wheat and maize, 2) monitor the changes in soil organic matter content under continuous wheat-maize cropping with different soil fertility management schemes, and 3) identify reasons for yield trends observed in Xuzhou City, Jiangsu Province, over a 20-year period. There were eight treatments applied to both wheat and maize seasons: a control treatment (C); three inorganic fertilizers, that is, nitrogen (N), nitrogen and phosphorus (NP), and nitrogen, phosphorus and potassium (NPK); and addition of farmyard manure (FYM) to these four treatments, that is, M, MN, MNP, and MNPK. At the end of the experiment the MN, MNP, and MNPK treatments had the highest yields, about 7 t wheat ha-1 and 7.5 t maize ha-1, with each about 1 t ha-1 more than the NPK treatments. Over 20 years with FYM soil organic matter increased by 80% compared to only 10% with NPK, which explained yield increases. However, from an environmental and agronomic perspective, manure application was not a superior strategy to NPK fertilizers. If manure was to be applied, though, it would be best applied to the wheat crop, which showed a better response than maize.JIANG Dong H.

3Transplantation of collagen scaffold with autologous bone marrow mononuclear cells promotes functional endometrium reconstruction via downregulating ΔNp63 expression in Asherman's syndrome显示文摘Asherman's syndrome(AS) is a common disease that presents endometrial regeneration disorder. However, little is known about its molecular features of this aregenerative endometrium in AS and how to reconstruct the functioning endometrium for the patients with AS. Here, we report that ΔNp63 is significantly upregulated in residual epithelial cells of the impaired endometrium in AS; the upregulated-ΔNp63 induces endometrial quiescence and alteration of stemness. Importantly, we demonstrate that engrafting high density of autologous bone marrow mononuclear cells(BMNCs) loaded in collagen scaffold onto the uterine lining of patients with AS downregulates ΔNp63 expression, reverses ΔNp63-induced pathological changes, normalizes the stemness alterations and restores endometrial regeneration. Finally, five patients achieved successful pregnancies and live births. Therefore, we conclude that ΔNp63 is a crucial therapeutic target for AS. This novel treatment significantly improves the outcome for the patients with severe AS.Guangfeng Zhao Yun Cao Xianghong Zhu Xiaoqiu Tang Lijun Ding Haixiang Sun Juan Li Xinan Li Chenyan Dai Tong Ru Hui Zhu Jingjie Lu Caimei Lin Jingmei Wang Guijun Yan Huiyan Wang Lei Wang Yimin Dai Bin Wang Ruotian Li Jianwu Dai Yan Zhou Yali Hu 2017Science China(Life Sciences)2017,60,4:39
4CB-Dock: a web server for cavity detection-guided protein–ligand blind docking显示文摘As the number of elucidated protein structures is rapidly increasing,the growing data call for methods to efficiently exploit the structural information for biological and pharmaceutical purposes.Given the three-dimensional(3D)structure of a protein and a ligand,predicting their binding sites and affinity are a key task for computer-aided drug discovery.To address this task,a variety of docking tools have been developed.Most of them focus on docking in the preset binding sites given by users.To automatically predict binding modes without information about binding sites,we developed a user-friendly blind docking web server,named CB-Dock,which predicts binding sites of a given protein and calculates the centers and sizes with a novel curvature-based cavity detection approach,and performs docking with a popular docking program,Autodock Vina.This method was carefully optimized and achieved^70% success rate for the top-ranking poses whose root mean square deviation(RMSD)were within 2Åfrom the X-ray pose,which outperformed the state-of-the-art blind docking tools in our benchmark tests.CB-Dock offers an interactive 3D visualization of results,and is freely available at http://gffzzdb39119b70414d18hwpwv6x6vn06p69qv.ffgz.tsg.suse.edu.cn/cb-dock/.Yang Liu Maximilian Grimm Wen-tao Dai Mu-chun Hou Zhi-Xiong Xiao Yang Cao 2020Acta Pharmacologica Sinica2020,41,1:36

The CSES satellite carries 8 instruments,including search-coil magnetometer(SCM), electric field detector(EFD), high precision magnetometer(HPM), GNSS occultation receiver(GOR), plasma analyzer package(PAP), langmuir probe(LAP), high energetic particle package(HEPP) and detector(HEPD), and tri-band beacon(TBB), among which HEPD is provided by Italian Space Agency. The CSES satellite was launched successfully on February 2, 2018, and is planned to operate for 5 years. The CSES mission is the first satellite in China to measure geophysical fields, which will have a lot of application prospects in the study of seismology, geophysics, space sciences, and so on.SHEN XuHui ZHANG XueMin YUAN ShiGeng WANG LanWei CAO JinBin HUANG JianPing ZHU Xing Hong PIERGIORGIO Picozzo DAI JianPing 2018Science China(Technological Sciences)2018,61,5:33
6Molecular screening of patients with nonsyndromic hearing loss from Nanjing city of China显示文摘Hearing loss is the most frequent sensory disorder involving a multitude of factors,and at least 50% of cases are due to genetic etiology.To further characterize the molecular etiology of hearing loss in the Chinese population,we recruited a total of 135 unrelated patients with nonsyndromic sensorineural hearing loss (NSHL) for mutational screening of GJB2,GJB3,GJB6,SLC26A4,SLC26A5 IVS2-2A>G and mitochondrial 12SrRNA,tRNA Ser(UCN) by PCR amplification and direct DNA sequencing.The carrier frequencies of deafness-causing mutations in these patients were 35.55% in GJB2,3.70% in GJB6,15.56% in SLC26A4 and 8.14% in mitochondrial 12SrRNA,respectively.The results indicate the necessity of genetic screening for mutations of these causative genes in Chinese population with nonsyndromic hearing loss.Yajie Lu Dachun Dai Zhibin Chen Xin Cao Xingkuan Bu Qinjun Wei Guangqian Xing 2011The Journal of Biomedical Research2011,25,5:30
7Late Triassic sedimentary records in the northern Tethyan Himalaya:Tectonic link with Greater India显示文摘The Upper Triassic flysch sediments(Nieru Formation and Langjiexue Group)exposed in the Eastern Tethyan Himalayan Sequence are crucial for unraveling the controversial paleogeography and paleotectonics of the Himalayan orogen.This work reports new detrital zircon U-Pb ages and whole-rock geochemical data for clastic rocks from flysch strata in the Shannan area.The mineral modal composition data suggest that these units were mainly sourced from recycled orogen provenances.The chemical compositions of the sandstones in the strata are similar to the chemical composition of upper continental crust.These rocks have relatively low Chemical Index of Alteration values(with an average of 62)and Index of Compositional Variability values(0.69),indicating that they experienced weak weathering and were mainly derived from a mature source.The geochemical compositions of the Upper Triassic strata are similar to those of graywackes from continental island arcs and are indicative of an acidicintermediate igneous source.Furthermore,hornblende and feldspar experienced decomposition in the provenance,and the sediment became enriched in zircon and monazite during sediment transport.The detrital zircons in the strata feature two main age peaks at 225-275 Ma and 500-600 Ma,nearly continuous Paleoproterozoic to Neoproterozoic ages,and a broad inconspicuous cluster in the Tonian-Stenian(800-1200 Ma).The detrital zircons from the Upper Triassic sandstones in the study area lack peaks at 300-325 Ma(characteristic of the Lhasa block)and 1150-1200 Ma(characteristic of the Lhasa and West Australia blocks).Therefore,neither the Lhasa block nor the West Australia blocks likely acted as the main provenance of the Upper Triassic strata.Newly discovered Permian-Triassic basalt and mafic dikes in the Himalayas could have provided the 225-275 Ma detrital zircons.Therefore,Indian and Himalayan units were the main provenances of the flysch strata.The Tethyan Himalaya was part of the northern passive margin and was not an exotic terrane separated from India during the Permian to Early Cretaceous.This evidence suggests that the Neo-Tethyan ocean opened prior to the Late Triassic and that the Upper Triassic deposits were derived from continental crustal fragments adjacent to the northern passive continental margin of Greater India.Huawen Cao Yong Huang Guangming Li Linkui Zhang Jianyang Wu Lei Dong Zuowen Dai Liu Lu 2018Geoscience Frontiers2018,9,1:27
8Expenditure and financial burden for the diagnosis and treatment of colorectal cancer in China:a hospital.based,multicenter,cross-sectional survey显示文摘Background: The increasing prevalence of colorectal cancer(CRC) in China and the paucity of information about relevant expenditure highlight the necessity of better understanding the financial burden and effect of CRC diagnosis and treatment. We performed a survey to quantify the direct medical and non-medical expenditure as well as the resulting financial burden of CRC patients in China.Methods: We conducted a multicenter, cross-sectional survey in 37 tertiary hospitals in 13 provinces across China between 2012 and 2014. Each enrolled patient was interviewed using a structured questionnaire. All expenditure data were inflated to the 2014 Chinese Yuan(CNY; 1 CNY = 0.163 USD). We quantified the overall expenditure and financial burden and by subgroup(hospital type, age at diagnosis, sex, education, occupation, insurance type, household income, clinical stage, pathologic type, and therapeutic regimen). We then performed generalized linear modeling to determine the factors associated with overall expenditure.Results: A total of 2356 patients with a mean age of 57.4 years were included, 57.1 % of whom were men; 13.9% of patients had stage I cancer; and the average previous-year household income was 54,525 CNY.The overall average direct expenditure per patient was estimated to be 67,408 CNY, and the expenditures for stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ disease were 56,099 CNY, 59,952 CNY, 67,292 CNY, and 82,729 CNY, respectively. Non-medical expenditure accounted for 8.3%of the overall expenditure. The 1-year out-of-pocket expenditure of a newly diagnosed patient was 32,649 CNY, which accounted for 59.9% of their previous-year household income and caused 75.0% of families to suffer an unmanageable financial burden. Univariate analysis showed that financial burden and overall expenditure differed in almost all subgroups(P < 0.05), except for sex. Multivariate analysis showed that patients who were treated in specialized hospitals and those who were diagnosed with adenocarcinoma or diagnosed at a later stage were likely to spend more,whereas those with a lower household income and those who underwent surgery spent less(all P < 0.05).Conclusions: For patients in China, direct expenditure for the diagnosis and treatment of CRC seemed catastrophic,and non-medical expenditure was non-ignorable. The financial burden varied among subgroups, especially among patients with different clinical stages of disease, which suggests that, in China, CRC screening might be cost-effective.Hui-Yao Huang Ju-Fang Shi Lan-Wei Guo Ya-Na Bai Xian-Zhen Liao Guo-iangLiu A-Yan Mao Jian-Song Ren Xiao-Jie Sun Xin-Yu Zhu Le Wang Bing-Bing Song Ling-Bin Du Lin Zhu Ji-Yong Gong Qi Zhou Yu-Qin Liu Rong Cao Ling Mai Li Lan Xiao-Hua Sun Ying Ren Jin-Yi Zhou Yuan-Zheng Wang Xiao Qi Pei-An Lou Dian Shi Ni Li Kai Zhang Jie He Min Dai 2017Chinese Journal of Cancer2017,36,8:25
9Species clarification of the prize medicinal Ganoderma mushroom“Lingzhi”显示文摘“Lingzhi”is a mushroom that has been renowned in China for more than 2,000 years because of its claimed medicinal properties plus its symbolic fortune.“Lingzhi”has high economic value mostly as a dietary supplement in the modern market especially in East Asia,and its medicinal functions have become a hot study topic.For over a century,the highly prized medicinal fungus,known as“Lingzhi”in East Asia,has been assigned to Ganoderma lucidum,a species originally described from Europe.Molecular studies in recent years have revealed that the commercially cultivated‘G.lucidum’(“Lingzhi”)in East Asia is a different species from the true G.lucidum.The present study aims to clarify the species identity of“Lingzhi”based on morphological studies and analysis of rDNA nuc-ITS sequences,and additional gene fragments of mt-SSU,RPB1,RPB2,and TEF1-αof“Lingzhi”were provided.All Ganoderma species that mostly resemble“Lingzhi”in phylogeny and/or morphology were included for analysis.We propose a new species G.lingzhi for“Lingzhi”,which has an East Asia distribution.The most striking characteristics which differentiate G.lingzhi from G.lucidum are the presence of melanoid bands in the context,a yellow pore surface and thick dissepiments(80–120μm)at maturity.G.curtisii is most closely related to G.lingzhi in phylogeny and is from North America.Ganoderma flexipes,G.multipileum,G.sichuanense,G.tropicum and‘G.tsugae’,are also closely related with G.lingzhi and are reported from China.These species are compared and discussed.‘Ganoderma tsuage’reported from China is determined as conspecific with G.lucidum,hence the distribution of G.lucidum extends from Europe to northeastern China.Yun Cao Sheng-Hua Wu Yu-Cheng Dai 2012Fungal Diversity2012,,5:25
10Distribution of polybrominated diphenyl ethers and decabromodiphenylethane in surface sediments from Fuhe River and Baiyangdian Lake,North China显示文摘Nineteen surface sediment samples collected from Baiyangdian Lake and its inflowing river (Fuhe River) in North China were analyzed for polybrominated diphenyl ethers (PBDEs) and decabromodiphenylethane (DBDPE).The concentrations of PBDEs and DBDPE in sediments ranged from 5.5 to 300.7 ng/g dry weight (dw) and 1.1 to 68.2 ng/g dw,respectively.Their levels in sediments in Fuhe River were significantly higher than those in Baiyandian Lake.Compared to data from other regions,the PBDE levels in surface sediments from Baiyangdian Lake and Fuhe River were in the medium to lower range.Among the PBDE congeners,BDE209 was predominant,with contributions to the total PBDEs ranging from 79.4% to 97.3% in sediment samples.For the lowly brominated congeners (tri-to hepta-BDE),BDE47 and BDE99 were the most abundant,which contributed 52.1% and 44.1% to the sum of tri-to hepta-BDEs in the sediments from Baiyangdian Lake and Fuhe River,respectively.The compositional patterns of PBDEs in Baiyangdian Lake sediments indicated that technical deca-BDE mixture was the major pollutant sources with a minor contribution of penta-BDE mixture.The present study suggested that the importance of Fuhe River as a possibly potential sources of PBDEs contamination in Baiyangdian Lake.Guocheng Hu Zhencheng Xu Jiayin Dai Bixian Mai Hong Cao Jianshe Wang Zhimin Shi Muqi Xu 2010Journal of Environmental Sciences2010,22,12:18
11Postponed and reduced basal nitrogen application improves nitrogen use efficiency and plant growth of winter wheat显示文摘Excessive nitrogen(N) fertilization with a high basal N ratio in wheat can result in lower N use efficiency(NUE) and has led to environmental problems in the Yangtze River Basin, China. However, wheat requires less N fertilizer at seedling growth stage, and its basal N fertilizer utilization efficiency is relatively low; therefore, reducing the N application rate at the seedling stage and postponing the N fertilization period may be effective for reducing N application and increasing wheat yield and NUE. A 4-year field experiment was conducted with two cultivars under four N rates(240 kg N ha–1(N240), 180 kg N ha–1(N180), 150 kg N ha–1(N150), and 0 kg N ha–1(N0)) and three basal N application stages(seeding(L0), fourleaf stage(L4), and six-leaf stage(L6)) to investigate the effects of reducing the basal N application rate and postponing the basal N fertilization period on grain yield, NUE, and N balance in a soil-wheat system. There was no significant difference in grain yield between the N180 L4 and N240 L0(control) treatments, and the maximum N recovery efficiency and N agronomy efficiency were observed in the N180 L4 treatment. Grain yield and NUE were the highest in the L4 treatment. The leaf area index, flag leaf photosynthesis rate, flag leaf nitrate reductase and glutamine synthase activities, dry matter accumulation, and N uptake post-jointing under N180 L4 did not differ significantly from those under N240 L0. Reduced N application decreased the inorganic N content in the 0–60-cm soil layer, and the inorganic N content of the L6 treatment was higher than those of the L0 and L4 treatments at the same N level. Surplus N was low under the reduced N rates and delayed basal N application treatments. Therefore, postponing and reducing basal N fertilization could maintain a high yield and improve NUE by improving the photosynthetic production capacity, promoting N uptake and assimilation, and reducing surplus N in soil-wheat systems.TIAN Zhong-wei LIU Xiao-xue GU Shi-lu YU Jin-hong ZHANG Lei ZHANG Wei-wei JIANG Dong CAO Wei-xing DAI Ting-bo 2018Journal of Integrative Agriculture2018,17,12:18
12Ability of human umbilical cord mesenchymal stem cells to repair chemotherapy-induced premature ovarian failure显示文摘BACKGROUND Premature ovarian insufficiency(POI)and premature ovarian failure(POF)have become one of the major problems threatening women of childbearing age.Studies have shown that stem cells transplanted from bone marrow,umbilical cord,peripheral blood and amniotic fluid can migrate and proliferate to the ovary,promote ovarian function repair,increase the number of follicles and granulosa cells at all levels of ovary,improve endocrine function,and can differentiate into oocytes in specific ovarian environment to restore fertility to some extent.AIM To study the ability of human umbilical cord mesenchymal stem cells(hUCMSCs)to repair ovarian injury after chemotherapy.METHODS A total of 110 female BALB/c mice(aged 7-8 wk old)with body masses of 16.0-20.0 g were selected.The mice were fed until 12 wk of age,and cyclophosphamide was administered by intraperitoneal injection for 14 consecutive days to induce premature ovarian failure in mice.Seventy-five mice with estrous cycle disorder were screened and randomly divided into 3 groups according to their body weight:model group,positive control group and hUCMSC group,and each group had 25 mice.Another 25 mice were used as negative controls.The mice in the hUCMSC group were injected with hUCMSCs in the tail vein,and the mice in the positive control group were given an oestradiol valerate solution and a medroxyprogesterone acetate solution in the tail vein.On the 1^st,15^th,30^th,45^th,and 60^th days after intravenous administration,vaginal smears were made to monitor the estrous cycles of the mice.The ovaries were weighed,and pathological sections were made to observe the morphology of the follicles;blood samples were collected to monitor the concentration of sex hormones(oestradiol and follicle-stimulating hormone).RESULTS The estrous cycles of the model group mice were disrupted throughout the experiment.Mice in the hUCMSC group and the positive control group resumed normal estrous cycles.The ovarian weight of the model group mice continued to decline.The ovarian weight of the hUCMSC group mice and the positive control group mice decreased first and then gradually increased,and the ovarian weight of the hUCMSC group mice was heavier than that of the positive control group mice.The difference was statistically significant(P<0.05).Compared with the negative control group,the model group experienced a decrease in oestradiol and an increase in follicle-stimulating hormone,and the difference was statistically significant(P<0.05).Compared with the model group,the hUCMSC and positive control groups experienced a slight increase in oestradiol and a decrease in follicle-stimulating hormone;the difference was statistically significant(P<0.05).The pathological examination revealed that the mouse ovaries from the model group were atrophied,the volume was reduced,the cortical and medullary structures were disordered,the number of follicles at all stages was significantly reduced,the number of atretic follicles increased,the number of primordial follicles and corpus luteum significantly decreased,and the corpus luteum had an irregular shape.Compared with those of the model group,the lesions of the hUCMSC and positive control groups significantly improved.CONCLUSION hUCMSCs can repair ovarian tissue damaged by chemotherapy to a certain extent,can improve the degree of apoptosis in ovarian tissue,and can improve the endocrine function of mouse ovaries.Jian Shen Dai Cao Jing-Li Sun 2020World Journal of Stem Cells2020,12,4:18
13Changing Connectivities of Chinese Cities in the World City Network,2010–2016显示文摘Against the backdrop of the sizable economic growth of China in recent years, this paper uses the most recent data gathering of the Globalization and World Cities(Ga WC) research network to update and supplement earlier research on the shifting global connectivity of Chinese cities. The update consists of an evaluation of the connectivity of Chinese cities in 2016, the supplement of an analysis of the changing position of Chinese cities in the world city network between 2010 and 2016. To this end, we build on a specification of the world city network as an ‘interlocking network' in which producer services firms play the crucial role in city network formation. Information about the presence of leading producer services firms in cities in 2010 and 2016 is used as the input to a bipartite network projection algorithm in order to measure cities' network connectivity. The first set of results discusses the geographies of urban connectivity in the world city network in 2016. The second set of results discusses standardized measures of change to reveal the major dimensions of the transformations between 2010 and 2016. We find that, with the exception of Hong Kong, Macao and Kaohsiung of Taiwan, all Chinese cities record connectivity gains. This wholesale rise in connectivity is nonetheless geographically uneven, with above all Beijing, Chengdu/Chongqing and Changsha/Wuhan becoming more connected. We conclude that the wholesale rise of Chinese cities in the world city network and their changing trajectories in the post-crisis era are embedded in shifting external and internal political economies.Ben DERUDDER CAO Zhan LIU Xingjian SHEN Wei DAI Liang ZHANG Weiyang Freke CASET Frank WITLOX Peter J.TAYLOR 2018Chinese Geographical Science2018,28,2:17

16Responses of the Toll-like receptor and melanoma differentiation-associated protein 5 signaling pathways to avian infectious bronchitis virus infection in chicks显示文摘Avian infectious bronchitis virus(IBV) is a Gammacoronavirus in the family Coronaviridae and causes highly contagious respiratory disease in chickens. Innate immunity plays significant roles in host defense against IBV. Here, we explored the interaction between IBV and the host innate immune system. Severe histopathological lesions were observed in the tracheal mucosa at 3–5days post inoculation(dpi) and in the kidney at 8 dpi, with heavy viral loads at 1–11 and 1–28 dpi,respectively. The expression of m RNAs encoding Toll-like receptor(TLR) 3 and TLR7 were upregulated at 3–8 dpi, and that of TIR-domain-containing adapter-inducing interferon(IFN) β(TRIF) was upregulated at 21 dpi in the trachea and kidney. Myeloid differentiation primary response protein 88(My D88) was upregulated in the trachea during early infection. Tumor necrosis factor receptor-associated factor(TRAF) 3 and TRAF6 were upregulated expression in both tissues.Moreover, melanoma differentiation-associated protein 5(MDA5), laboratory of genetics and physiology 2(LGP2), stimulator of IFN genes(STING), and mitochondrial antiviral signaling protein(MAVS), as well as TANK binding kinase 1(TBK1), inhibitor of kappa B kinase(IKK) ?, IKKα, IKKβ,IFN regulatory factor(IRF) 7, nuclear factor of kappa B(NF-κB), IFN-α, IFN-β, various interleukins(ILs), and macrophage inflammatory protein-1β(MIP-1β) were significantly upregulated in the trachea and downregulated in the kidney. These results suggested that the TLR and MDA5 signaling pathways and innate immune cytokine were induced after IBV infection. Additionally,consistent responses to IBV infection were observed during early infection, with differential and complicated responses in the kidney.Yining He Zhiwen Xie Jinglong Dai Yanjie Cao Jinlian Hou Yansheng Zheng Tianchao Wei Meilan Mo Ping Wei 2016Virologica Sinica2016,31,1:14
17Modular growth and clonal propagation of Hippophae rhamnoides subsp, sinensis in response to irrigation intensity显示文摘A multipurpose clone plant species,Hippophae rhamniodes has the capacity for indefinite longevity,although under successive drought stress it may often decline or die across large areas.Field trials were conducted over 2 years to examine the effects of varied irrigation intensities on modular growth and clonal propagation in a semi-arid area.Irrigation levels included a control,as well as two,four and six times the volume of water that was typically received via local annual average precipitation.Irrigation intensity significantly influenced clonal propagation capacity(number of daughter ramets),aboveground modular growth(height,base diameter,and crown width),belowground modular growth included root nodule dry weight,stretching capacity of lateral roots(length of the longest lateral roots,and diameter of firstgrade lateral roots),and branching intensity of lateral roots(number of lateral roots bifurcation grade,number of firstgrade lateral roots).The modular growth and the density of daughter ramets were small under non-irrigation or low irrigation,and became larger with increased irrigation intensity.Beyond a certain threshold,however,further increases in irrigation intensity resulted in a reversion to the development.The optimal irrigation intensities for growth and propagation were 3.48–5.29 times the volume of nominal local annual average precipitation.There were effects of irrigation intensities on the positive significant correlations between aboveground and belowground modular growths,and on clonal propagation capacities.Under various water treatments,H.rhamnoides may adapt to the environment through the regulation of growth and propagation.We concluded that water shortages act to weaken the growth and propagation of H.rhamniodes plantations.Zilin Cao Tianjiang Li Genqian Li Chunhong Liu Haiyin Gao Guanghui Dai Zhiyong Xiao Sunling Li 2016Journal of Forestry Research2016,27,5:14

19Prognostic value and predictive threshold of tumor volume for patients with locally advanced nasopharyngeal carcinoma receiving intensity-modulated radiotherapy显示文摘Background: Gross target volume of primary tumor(GTV?P) is very important for the prognosis prediction of patients with nasopharyngeal carcinoma(NPC), but it is unknown whether the same is true for locally advanced NPC patients treated with intensity?modulated radiotherapy(IMRT). This study aimed to clarify the prognostic value of tumor volume for patient with locally advanced NPC receiving IMRT and to ind a suitable cut?of value of GTV?P for prognosis prediction.Methods: Clinical data of 358 patients with locally advanced NPC who received IMRT were reviewed. Receiver oper?ating characteristic(ROC) curves were used to identify the cut?of values of GTV?P for the prediction of diferent end?points [overall survival(OS), local relapse?free survival(LRFS), distant metastasis?free survival(DMFS), and disease?free survival(DFS)] and to test the prognostic value of GTV?P when compared with that of the American Joint Committee on Cancer T staging system.Results: The 358 patients with locally advanced NPC were divided into two groups by the cut?of value of GTV?P as determined using ROC curves: 219(61.2%) patients with GTV?P ≤46.4 mL and 139(38.8%) with GTV?P >46.4 mL. The 3?year OS, LRFS, DMFS, and DFS rates were all higher in patients with GTV?P ≤46.4 mL than in those with GTV?P > 46.4 mL(all P < 0.05). Multivariate analysis indicated that GTV?P >46.4 mL was an independent unfavorable prognostic factor for patient survival. The ROC curve veriied that the predictive ability of GTV?P was superior to that of T category(P < 0.001). The cut?of values of GTV?P for the prediction of OS, LRFS, DMFS, and DFS were 46.4, 57.9, 75.4 and 46.4 mL, respectively.Conclusion: In patients with locally advanced NPC, GTV?P >46.4 mL is an independent unfavorable prognostic indi?cator for survival after IMRT, with a prognostic value superior to that of T category.Yu-Xiang He Ying Wang Peng-Fei Cao Lin Shen Ya-Jie Zhao Zi-Jian Zhang Deng-Ming Chen Tu-Bao Yang Xin-Qiong Huang Zhou Qin You-Yi Dai Liang-Fang Shen 2016Chinese Journal of Cancer2016,35,12:12
20Carbon pools and fluxes in the China Seas and adjacent oceans显示文摘The China Seas include the South China Sea, East China Sea, Yellow Sea, and Bohai Sea. Located off the Northwestern Pacific margin, covering 4700000 km^2 from tropical to northern temperate zones, and including a variety of continental margins/basins and depths, the China Seas provide typical cases for carbon budget studies. The South China Sea being a deep basin and part of the Western Pacific Warm Pool is characterized by oceanic features; the East China Sea with a wide continental shelf, enormous terrestrial discharges and open margins to the West Pacific, is featured by strong cross-shelf materials transport; the Yellow Sea is featured by the confluence of cold and warm waters; and the Bohai Sea is a shallow semiclosed gulf with strong impacts of human activities. Three large rivers, the Yangtze River, Yellow River, and Pearl River, flow into the East China Sea, the Bohai Sea, and the South China Sea, respectively. The Kuroshio Current at the outer margin of the Chinese continental shelf is one of the two major western boundary currents of the world oceans and its strength and position directly affect the regional climate of China. These characteristics make the China Seas a typical case of marginal seas to study carbon storage and fluxes. This paper systematically analyzes the literature data on the carbon pools and fluxes of the Bohai Sea,Yellow Sea, East China Sea, and South China Sea, including different interfaces(land-sea, sea-air, sediment-water, and marginal sea-open ocean) and different ecosystems(mangroves, wetland, seagrass beds, macroalgae mariculture, coral reefs, euphotic zones, and water column). Among the four seas, the Bohai Sea and South China Sea are acting as CO_2 sources, releasing about0.22 and 13.86–33.60 Tg C yr^(-1) into the atmosphere, respectively, whereas the Yellow Sea and East China Sea are acting as carbon sinks, absorbing about 1.15 and 6.92–23.30 Tg C yr^(-1) of atmospheric CO_2, respectively. Overall, if only the CO_2 exchange at the sea-air interface is considered, the Chinese marginal seas appear to be a source of atmospheric CO_2, with a net release of 6.01–9.33 Tg C yr^(-1), mainly from the inputs of rivers and adjacent oceans. The riverine dissolved inorganic carbon (DIC) input into the Bohai Sea and Yellow Sea, East China Sea, and South China Sea are 5.04, 14.60, and 40.14 Tg C yr^(-1),respectively. The DIC input from adjacent oceans is as high as 144.81 Tg C yr^(-1), significantly exceeding the carbon released from the seas to the atmosphere. In terms of output, the depositional fluxes of organic carbon in the Bohai Sea, Yellow Sea, East China Sea, and South China Sea are 2.00, 3.60, 7.40, and 5.92 Tg C yr^(-1), respectively. The fluxes of organic carbon from the East China Sea and South China Sea to the adjacent oceans are 15.25–36.70 and 43.93 Tg C yr^(-1), respectively. The annual carbon storage of mangroves, wetlands, and seagrass in Chinese coastal waters is 0.36–1.75 Tg C yr^(-1), with a dissolved organic carbon(DOC) output from seagrass beds of up to 0.59 Tg C yr^(-1). Removable organic carbon flux by Chinese macroalgae mariculture account for 0.68 Tg C yr^(-1) and the associated POC depositional and DOC releasing fluxes are 0.14 and 0.82 Tg C yr^(-1), respectively. Thus, in total, the annual output of organic carbon, which is mainly DOC, in the China Seas is 81.72–104.56 Tg C yr^(-1). The DOC efflux from the East China Sea to the adjacent oceans is 15.00–35.00 Tg C yr^(-1). The DOC efflux from the South China Sea is 31.39 Tg C yr^(-1). Although the marginal China Seas seem to be a source of atmospheric CO_2 based on the CO_2 flux at the sea-air interface, the combined effects of the riverine input in the area, oceanic input, depositional export,and microbial carbon pump(DOC conversion and output) indicate that the China Seas represent an important carbon storage area.Nianzhi JIAO Yantao LIANG Yongyu ZHANG Jihua LIU Yao ZHANG Rui ZHANG Meixun ZHAO Minhan DAI Weidong ZHAI Kunshan GAO Jinming SONG Dongliang YUAN Chao LI Guanghui LIN Xiaoping HUANG Hongqiang YAN Limin HU Zenghu ZHANG Long WANG Chunjie CAO Yawei LUO Tingwei LUO Nannan WANG Hongyue DANG Dongxiao WANG Si ZHANG 2018Science China Earth Sciences2018,61,11:12
