2Application of LICOM to the numerical study of the water exchange between the South China Sea and its adjacent oceans显示文摘On the basis of 900-year integration of a global ocean circulation model—LICOM driven by ECMWF reanalysis wind data with uni-form 0.5°-grids, a quantitative estimate of the annual and monthly mean water exchange of the South China Sea (SCS) with its adjacentoceans through 5 straits is obtained. Among them, the annual transport is the largest in the Luzon Strait, then in the Taiwan Strait, andthen in the Sunda Shelf, in the Balabac Strait and in the Mindoro Strait in turn, the largest monthly transport variation appears in theLuzon Strait and Sunda shelf. It is shown that the mass transport through the Taiwan Strait is affected by monsoon, while the transportthrough the Luzon Strait may be associated with the bifurcation position of the North Equatorial Current off the east Philippines shore;the transports in the Luzon Strait and Sunda Shelf are out of phase in direction but well correlated in magnitude. The annual andmonthly mean heat and salinity exchange of the SCS through the straits are also calculated and shown to be in phase with the masstransport. The Kuroshio water carries about 0.43 PW heat transport and 151.33 kt/s salinity transport into the SCS, while most of themis carried out of the SCS through the Taiwan Strait and Sunda Shelf annually. The further model integration based on the 900-year inte-gration for another 44 a from 1958 to 2001 driven by real wind data (ERA40 data) shows that the monthly mean mass transport viathese straits varies annually with a large variation range, which may be associated with the seasonal and interannual variations in thecurrent field and sea surface height in the SCS. The mean mass transport through the Taiwan Strait, Luzon Strait, Mindoro Strait, Bal-abac Strait and Sunda Shelf is 2.012 × 106, -4.063 × 106, -0.124 × 106, -0.083 × 106 and 2.258 × 106 m3/s, respectively.CAI Shuqun LIU Hailong LI Wei LONG Xiaomin 2005Acta Oceanologica Sinica2005,24,4:24

5Ni-_2P-MoS_2/γ-Al_2O_3 Catalyst for Deep Hydrodesulfurization via the Hydrogenation Reaction Pathway显示文摘A series of highly active Ni2P-Mo S2/γ-Al2O3 catalysts were prepared and characterized, the catalytic performance of which was evaluated through hydrodesulfurization of dibenzothiophene. The result indicated that when the amount of Ni2 P was 4%, the catalyst showed a relatively high activity to provide a reliable reference for the hydrodesulfurization pathway in comparison with the conventional Ni Mo and Ni Mo P catalysts. The physicochemical properties of the catalysts were correlated with their catalytic activity and selectivity on hydrodesulfurization. The stacking number of active Mo S2 phases was important for influencing the hydrogenation activity.Liu Lihua Liu Shuqun 2014China Petroleum Processing & Petrochemical Technology2014,16,4:13
6The effect of a seasonal stratification variation on the load exerted by internal solitary waves on a cylindrical pile显示文摘On the basis of Morison's empirical formula and modal separation method in estimating the force and torque exerted by internal solitary waves(ISWs) on a cylindrical pile, it is found that the loads exerted by the ISWs change largely in different seasons at the same site of the continental shelf in the South China Sea(SCS) even under the condition that the amplitudes of ISWs are the same. Thus, the effect of a seasonal water stratification variation on the force and torque exerted by the ISWs is investigated, and a three-parameter stratification model is employed. It is shown that the loads exerted by the ISWs depend largely on the water stratification. The stronger the water stratification, the larger the force and the torque; when the depth where the maximum thermocline appears is deepened, the force decreases but the torque increases; when the width of the thermocline is narrowed, the force increases but the torque decreases. The seasonal variation of the force and the torque exerted by the ISWs in four seasons in the SCS is thus explained.CAI Shuqun XU Jiexin CHEN Zhiwu XIE Jieshuo DENG Xiaodong LV Haibin 2014Acta Oceanologica Sinica2014,33,7:9
7Antitumor Research on Artemisinin and Its Bioactive Derivatives显示文摘Cancer is the leading cause of human death which seriously threatens human life.The antimalarial drug artemisinin and its derivatives have been discovered with considerable anticancer properties.Simultaneously,a variety of target-selective artemisinin-related compounds with high efficiency have been discovered.Many researches indicated that artemisinin-related compounds have cytotoxic effects against a variety of cancer cells through pleiotropic effects,including inhibiting the proliferation of tumor cells,promoting apoptosis,inducing cell cycle arrest,disrupting cancer invasion and metastasis,preventing angiogenesis,mediating the tumor-related signaling pathways,and regulating tumor microenvironment.More importantly,artemisinins demonstrated minor side effects to normal cells and manifested the ability to overcome multidrug-resistance which is widely observed in cancer patients.Therefore,we concentrated on the new advances and development of artemisinin and its derivatives as potential antitumor agents in recent 5 years.It is our hope that this review could be helpful for further exploration of novel artemisinin-related antitumor agents.Yunqin Zhang Guowei Xu Shuqun Zhang Dong Wang PSaravana Prabha Zhili Zuo 2018Natural Products and Bioprospecting2018,8,4:8
8Mitogen-activated protein kinase cascades in plant signaling显示文摘Mitogen-activated protein kinase(MAPK)cascades are key signaling modules downstream of receptors/sensors that perceive either endogenously produced stimuli such as peptide ligands and damage-associated molecular patterns(DAMPs)or exogenously originated stimuli such as pathogen/microbe-associated molecular patterns(P/MAMPs),pathogen-derived effectors,and environmental factors.In this review,we provide a historic view of plant MAPK research and summarize recent advances in the establishment of MAPK cascades as essential components in plant immunity,response to environmental stresses,and normal growth and development.Each tier of the MAPK cascades is encoded by a small gene family,and multi ple members can function redundantly in an MAPK cascade.Yet,they carry out a diverse array of biological functions in plants.How the signaling specificity is achieved has become an interesting topic of MAPK research.Future investigations into the molecular mechanism(s)underlying the regulation of MAPK activation including the activation kinetics and magnitude in response to a stimulus,the spatiotemporal expression patterns of all the components in the signaling pathway,and functional characterization of novel MAPK substrates are central to our understanding of MAPK functions and signaling specificity in plants.Mengmeng Zhang Shuqun Zhang 2022Journal of Integrative Plant Biology2022,64,2:8
9Advances in research of the mid-deep South China Sea circulation显示文摘The South China Sea(SCS)is a large marginal sea connecting the Indian and Pacific oceans.Under the factors of monsoons,strait transport,and varied bathymetry,the SCS presents a three-layer structure and strong diapycnal mixing which is far greater than that in the open ocean.Theoretical analysis and observations reveal that internal tides,internal solitary waves,and strong winds are the sources of the strong mixing in the northern SCS.A major consequence of the strong mixing is an active mid-deep circulation system.This system promotes exchange of water between the SCS and adjacent oceans,and also regulates the upper layer of wind-driven circulation,making the 3 dimensional SCS circulation clearly different from that in other tropical and subtropical marginal seas.The mass transport capacity of the mid-deep circulation has a substantial impact on marine sedimentation,the biogeochemical cycle,and other processes in the SCS.This paper summarizes the recent advances in middeep sea circulation dynamics of the SCS,and discusses the opportunities and challenges in this area.Dongxiao WANG Qiang WANG Shuqun CAI Xiaodong SHANG Shiqiu PENG Yeqiang SHU Jingen XIAO Xiaohui XIE Zhiwei ZHANG Zhiqiang LIU Jian LAN Dake CHEN Huijie XUE Guihua WANG Jianping GAN Xinong XIE Rui ZHANG Hui CHEN Qingxuan YANG 2019Science China Earth Sciences2019,62,12:8
10Co-regulation of indole glucosinolates and camalexin biosynthesis by CPK5/CPK6 and MPK3/MPK6 signaling pathways^°°显示文摘Secondary plant metabolites,represented by indole glucosinolates(IGS)and camalexin,play important roles in Arabidopsis immunity.Previously,we demonstrated the importance of MPK3 and MPK6,two closely related MAPKs,in regulating Botrytis cinerea(Bc)-induced IGS and camalexin biosynthesis.Here we report that CPK5 and CPK6,two redundant calcium-dependent protein kinases(CPKs),are also involved in regulating the biosynthesis of these secondary metabolites.The loss-of-function of both CPK5 and CPK6 compromises plant resistance to Be.Expression profiling of CPK5-VK transgenic plants,in which a truncated constitutively active CPK5 is driven by a steroidinducible promoter,revealed that biosynthetic genes of both IGS and camalexin pathways are coordinately upregulated after the induction of CPK5-VK,leading to high-level accumulation of camalexin and 4-methoxyindole-3-ylmethylglucosinolate(4MI3G).Induction of camalexin and 4MI3G,as well as the genes in their biosynthesis pathways,is greatly compromised in cpks cpk6 mutant in response to Be.In a conditional cpk5 cpk6 mpk3 mpk6 quadruple mutant,Be resistance and induction of IGS and camalexin are further reduced in comparison to either cpks cpk6 or conditional mpk3 mpk6 double mutant,suggesting that both CPK5/CPK6 and MPK3/MPK6 signaling pathways contribute to promote the biosynthesis of 4MI3G and camalexin in defense against Be.Liuyi Vang Yan Zhang Rongxia Guan Sen Li Xuwen Xu Shuqun Zhang Juan Xu 2020Journal of Integrative Plant Biology2020,62,11:6
11The YDA-MKK4/MKK5-MPK3/MPK6 Cascade Functions Downstream of the RGF1-RGI Ligand-Receptor Pair in Regulating Mitotic Activity in Root Apical Meristem显示文摘The mitotic activity of root apical meristem(RAM)is critical to primary root growth and development.Previous studies have identified the roles of ROOT GROWTH FACTOR 1(RGF1),a peptide ligand,and its receptors,RGF1 INSENSITIVEs(RGIs),a clade of five leucine-rich-repeat receptor-like kinases,in promoting cell division in the RAM,which determines the primary root length.However,the downstream signaling components remain elusive.In this study,we identify a complete mitogen-activated protein kinase(MAPK or MPK)cascade,composed of YDA,MKK4/MKK5,and MPK3/MPK6,that functions downstream of the RGF1-RGI ligand-receptor pair.Similar to the rgi1/2/3/4/5 quintuple mutant,loss-of-function mutants of MPK3 and MPK6,MKK4 and MKK5,or YDA show a short-root phenotype,which is associated with reduced mitotic activity and lower expression of PLETHORA 1(PLT1)/PLT2 in the RAM.Furthermore,MPK3/MPK6 activation in response to exogenous RGF1 treatment is impaired in the rgi1/2/3/4/5 quintuple,yda single,and mkk4 m kk5 double mutants.Epistatic analyses demonstrated that the expression of constitutively active MKK4,MKK5,or YDA driven by the RGI2 promoter can rescue the short-root phenotype of the rgi1/2/3/4/5 mutant.Taken together,these results suggest that the YDA-MKK4/MKK5-MPK3/MPK6 cascade functions downstream of the RGF1-RGI ligand-receptor pair and upstream of PLT1/PLT2 to modulate the stem cell population and primary root growth in Arabidopsis.Yiming Shao Xinxing Yu Xuwen Xu Yong Li Wenxin Yuan Yan Xu Chuanzao Mao Shuqun Zhang Juan Xu 2020Molecular Plant2020,13,11:6
12The response of spring phytoplankton assemblage to diluted water and upwelling in the eutrophic Changjiang(Yangtze River) Estuary显示文摘A comprehensive study on the phytoplankton standing stocks, species composition and dominant species in the eutrophic Changjiang(Yangtze River) Estuary(CE) was conducted to reveal the response of phytoplankton assemblage to Changjiang Diluted Water(CDW) and upwelling in the spring. Phytoplankton presented peak standing stocks(13.03 μg/L of chlorophyll a, 984.5×103 cells/L of phytoplankton abundance) along the surface isohaline of 25. Sixty-six species in 41 genera of Bacillariophyta and 33 species in 19 genera of Pyrrophyta were identified, as well as 5 species in Chlorophyta and Chrysophyta. Karenia mikimotoi was the most dominant species, followed by Prorocentrum dentatum, Paralia sulcata, Pseudo-nitzschia delicatissima and Skeletonema costatum. A bloom of K. mikimotoi was observed in the stratified stations, where the water was characterized by low nitrate, low phosphate, low turbidity, and specific ranges of temperature(18–22 °C) and salinity(27–32). K.mikimotoi and P. dentatum accumulated densely in the upper layers along the isohaline of 25. S. costatum was distributed in the west of the isohaline of 20. Benthonic P. sulcata presented high abundance near the bottom,while spread upward at upwelling stations. CDW resulted in overt gradients of salinity, turbidity and nutritional condition, determining the spatial distribution of phytoplankton species. The restricted upwelling resulted in the upward transport of P. sulcata and exclusion of S. costatum, K. mikimotoi and P. dentatum. The results suggested that CDW and upwelling were of importance in regulating the structure and distribution of phytoplankton assemblage in the CE and the East China Sea.SONG Shuqun LI Zhao LI Caiwen YU Zhiming 2017Acta Oceanologica Sinica2017,36,12:5
13Modeling of suspended sediment by coupled wave-current model in the Zhujiang(Pearl) River Estuary显示文摘A three-dimensional wave-current-sediment coupled numerical model is developed to understand the sediment transport dynamics in the Zhujiang(Pearl)River Estuary(ZRE),China.The model results are in good agreement with observed data,and statistics show good model skill scores.Numerical studies are conducted to assess the scenarios of suspended sediment in the ZRE under the effects of different forcing(river discharges,waves,and winds).The model results indicate that the estuarine gravitational circulation plays an important role in the development of estuarine turbidity maximum in the ZRE,particularly during neap tides.The increased river discharge can result in a seaward sediment transport.The suspended sediment concentration(SSC)in the bottom increases with both wave bottom orbital velocity and wave height.Because of the shallow water depth,the effect of waves on sediment in the west shoal is greater than that in the east channel.The southwesterly wind-induced wave affects the SSC more than those resulting from the northeasterly wind,while the northeasterly wind-driven circulation has a slightly greater influence on the SSC than that of the southwesterly wind.However,a steady southwesterly wind condition favors the increase of the SSC in the Lingding Bay more so than a steady northeasterly wind condition.If the other forcings are same,the averaged SSC under a steady southwesterly wind condition is about 1.1 times that resulting from a steady northeasterly wind.Guangping Liu Shuqun Cai 2019Acta Oceanologica Sinica2019,38,7:4
14Diurnal wind and nonlinear interaction between inertial and tidal currents in the South China Sea during the passage of Typhoon Conson显示文摘Diurnal wind(DW) and nonlinear interaction between inertial and tidal currents near the Xisha Islands of the South China Sea(SCS) during the passage of Typhoon Conson(2010) are investigated using observational data and a damped slab model. It is found that the DWs, which are dominated by clockwise wind components, are prominent at our observational site. The DWs increase after the passage of the typhoon from 1 to about 4 m/s, which may be due to the decrease of the sea surface temperature caused by the passage of the typhoon. Kinetic energy spectra and bicoherence methods reveal nonlinear interactions between the inertial currents and the 2MK3 tidal constituent at our observational site. The slab damped model reproduces the inertial currents successfully induced by the total observed winds, and it is shown that the inertial currents induced by DWs are positively proportional to the DWs speed. Even though the observed inertial currents are distinct, the proportion of inertial currents induced by DWs to those induced by the total observed winds is just 0.7%/4% before/after the passage of typhoon. This shows that the inertial currents induced by the DWs are unimportant near the Xisha Islands during the typhoon season.LIU Junliang CAI Shuqun WANG Shengan 2014Acta Oceanologica Sinica2014,33,5:4
15The lifestyle transition of Arthrobotrys oligospora is mediated by microRNA-like RNAs显示文摘The lifestyle transition of fungi,defined as switching from taking organic material as nutrients to pathogens,is a fundamental phenomenon in nature.However,the mechanisms of such transition remain largely unknown.Here we show microRNA-like RNAs(milRNAs)play a key role in fungal lifestyle transition for the first time.We identified milRNAs by small RNA sequencing in Arthrobotrys oligospora,a known nematode-trapping fungus.Among them,7 highly expressed milRNAs were confirmed by northern-blot analysis.Knocking out two milRNAs significantly decreased A.oligospora’s ability to switch lifestyles.We further identified that two of these milRNAs were associated with argonaute protein QDE-2 by RNA-immunoprecipitation(RIP)analysis.Three of the predicted target genes of milRNAs were found in immunoprecipitation(IP)products of QDE-2.Disruption of argonaute gene qde-2 also led to serious defects in lifestyle transition.Interestingly,knocking out individual milRNAs or qde-2 lead to diverse responses under different conditions,and qde-2 itself may be targeted by the milRNAs.Collectively,it indicates the lifestyle transition of fungi is mediated by milRNAs through RNA interference(RNAi)machinery,revealing the wide existence of miRNAs in fungi kingdom and providing new insights into understanding the adaptation of fungi from scavengers to predators and the mechanisms underlying fungal infections.Xinglai Ji Heng Li Weihua Zhang Jiai Wang Lianming Liang Chenggang Zou Zefen Yu Shuqun Liu Ke-Qin Zhang 2020Science China(Life Sciences)2020,63,4:4

17Typing of biliary tumor thrombus influences the prognoses of patients with hepatocellular carcinoma显示文摘Objective:To establish a new classification of biliary tumor thrombus(BTT).Methods:Overall survival of patients with BTT was first used to determine whether it correlated with current hepatocellular carcinoma staging systems.Univariate and multivariate analyses were used to determine factors affecting the overall survival(OS)to form the basis of our new classification for BTT.Results:All 6 international staging systems showed overlapping survival curves.Univariate followed by multivariate analyses showed that total bilirubin and intrahepatic/extrahepatic BTT were significant risk factors of OS.Based on these data,a new BTT classification was defined as:TypeⅠ:intrahepatic BTT;and TypeⅡ:extrahepatic BTT involving a common bile duct or common hepatic duct.TypeⅠwas further subdivided into type Ia:BTT involving a second-order intrahepatic duct or above,and type Ib:BTT involving a first-order intrahepatic duct.TypeⅡwas further subdivided into typeⅡa and typeⅡb using a cut-off total bilirubin(TB)>300μmol/L.The numbers(percentages)of patients with typesⅠandⅡBTT were 69(34.2%)and 133(65.8%),respectively.The median OS of typeⅠpatients was significantly higher than that of typeⅡpatients(37.5 months vs.23.2 months;P=0.002).Using subgroup analyses,OS outcomes were significantly different between the subgroups of typeⅡb and type IIa,although there was no significant difference between the type Ia and type Ib subgroups(P=0.07).Conclusions:A new BTT classification was established to predict prognoses of HCC patients with BTT who underwent liver resection.Juxian Sun Jiayi Wu Chang Liu Jie Shi Yonggang Wei Jianyin Zhou Zhibo Zhang Wan Yee Lau Maolin Yan Shuqun Cheng 2021Cancer Biology & Medicine2021,18,3:3

19Is there a close relationship between synonymous codon bias and codon-anticodon binding strength in human genes?显示文摘Synonymous codon bias has been examined in 78 human genes (19967 codons) and measured by relative synonymous codon usage (RSCU). Relative frequencies of all kinds of dinucleotides in 2,3 or 3,4 codon positions have been calculated, and codon-anticodon binding strength has been estimated by the stacking energies of codon-anticodon bases in Watson-Crick pairs. The data show common features in synonymous codon bias for all codon families in human genes: all C-ending codons, which possess the strongest codon-anticodon binding energies, are the most favored codons in almost all codon families, and those codons with medium codon-anticodon binding energies are avoided. Data analysis suggests that besides isochore and genome signature, codon-anticodon binding strength may be closely related to synonymous codon choice in human genes. The join-effect of these factors on human genes results in the common features in codon bias.Xiufan Shi Jingfei Huang Chongrong Liang Shuqun Liu Jun Xie Ciquan Liu 2001Chinese Science Bulletin2001,46,12:2
20高能聚束微波热疗联合沙培林胸腔注射治疗恶性胸水(英文)显示文摘Objective:The aim of the study was to evaluate the efficacy and toxicity of high power focused-beam microwave hyperthermia with intrapleural injection of Shapeilin for patients with malignant hydrothorax.Methods:Fifty-eight patients with malignant hydrothorax were divided into group A and group B randomly.All patients underwent indwelling pleural catheter and were treated by intrapleural injection of Shapeilin once three days.Treatment was composed of 3 times injection.Patients of group B received high power focused-beam microwave hyperthermia after injection of Shapeilin.Results:The response rate of group B(79.3%) was higher than that of group A(48.3%)(P < 0.05).Incidence of main adverse reactions,associated with Shapeilin,of two groups including fever and thoracodynia were similar(P > 0.05).Patients of group B didn't encounter severe toxicities of microwave hyperthermia.Conclusion:High power focused-beam microwave hyperthermia combined with intrapleural injection of Shapeilin is effective and tolerable for patients with malignant hydrothorax.Lingqin Song Jianjun He Xijing Wang Hongbing Ma Shuqun Zhang Zhijun Dai Baofeng Wang Xiaobin Ma 2011The Chinese-German Journal of Clinical Oncology2011,10,2:2
