1Clinical analysis of intracranial germinoma's craniospinal irradiation using helical tomotherapy显示文摘Objective: To evaluate the short-term clinical outcomes of intracranial germinoma patients treated with craniospinal irradiation(CSI) using helical tomotherapy(HT) system in our center. Methods: Twenty-three patients who were treated with CSI in our center from January 2008 to July 2012 were collected, with an average age of 20. All of the patients' CSI used the HT system. The total doses were 27-36 Gy/15-20 F(1.5-2 Gy per fraction), and total local doses were 46-60 Gy/30-50 F(5 fractions per week). All female patients for CSI were treated with left-right parallel-opposed field irradiation to protect their ovarian functions. Median follow-up time was 30.9 months(range, 5-67 months). The SPSS19.0 software was used, and the overall survival(OS) was calculated using the Kaplan-Meier method.Results: Among 17 patients with assessable tumors, 9 cases(52.9%) were CR, 7 cases(41.2%) were PR, and 1 case(5.9%) was SD. Hematological toxicity was the severest side-effect occurred in the procedure of CSI. The level 1-4 acute leukopenia were 8.7%, 30.4%, 34.8% and 21.7% and the level 1-4 acute thrombopenia were 8.7%, 30.4%, 21.7% and 8.7%, respectively.Conclusions: For primary intracranial germinomas, HT can be used to implement CSI for simplifying radiotherapy procedures, improving radiotherapy accuracy, enhancing protection of peripheral organs at risk(ORA) and guaranteeing therapeutic effects. With the acceptable acute and long-term toxicity, CSI using HT in intracranial germinoma patients can be a safe and alternative mode.Baolin Qu Lei Du Yurong Huang Wei Yu Boning Cai Shouping Xu Lin Ma 2014Chinese Journal of Cancer Research2014,26,3:14
2Comparative Analysis of Nutrient Composition of Caulerpa lentillifera from Different Regions显示文摘This study investigated the difference of nutrient composition in Caulerpa lentillifera collected from different regions.The nutrient compositions of C.lentillifera from China's Hainan and Shandong provinces were determined and compared with those from Semporna(Malaysia),Sabah(Malaysia),Petchburi(Thailand),and two other species of seaweeds(Malaysia).The results showed that the polysaccharide and protein contents of C.lentillifera from Hainan(44.82%±0.98%and 12.5%±0.70%),Shandong(43.22%±1.42%and 14.7%±0.72%),Petchburi(59.27%±2.31%and 12.49%±0.30%),and Sabah(44.02%±2.01%and 19.38%±1.48%)were higher than those of Eucheuma cottonii(26.49%±3.01%and 9.76%±1.33%)and Sargassum polycystum(33.49%±1.70%and 5.40%±0.07%),respectively.The polyunsaturated fatty acid contents in C.lentillifera from Hainan(29.98%)and Shandong(22.11%)were higher than that in Semporna(16.76%±0.27%),Sabah(9.49%),and S.polycystum(20.34%±0.43%),but lower than that in E.cottonii(51.55%±0.57%).In Caulerpa lentillifera of Hainan and Shandong provinces,the essential amino acid(EAA)/total amino acid(TAA)ratios were 35.22%and 38.78%,respectively;and the EAA/ETAA ratios were 54.36%and 63.35%,respectively.The EAA composition of C.lentillifera was close to the ideal model of Food and Agriculture Organization/World Health Organization.C.lentillifera was rich in mineral elements,including calcium((3315.85±127.55)mg(100 g)^-1 and(3728.35±92.38)mg(100 g)^-1),magnesium((6715.74±82.58)mg(100 g)^-1 and(8128.59±242.72)mg(100 g)^-1),and trace elements,including iron((510.65±5.47)mg(100 g)^-1 and(1972.97±183.35)mg(100 g)^-1),selenium((1.04±0.08)mg(100 g)^-1 and(0.83±0.15)mg(100 g)^-1),and zinc((33.90±0.13)mg(100 g)^-1 and(11.75±2.05)mg(100 g)^-1).These results showed that C.lentillifera was more nutritious than S.polycystum or E.cottonii in terms of polysaccharide,protein,and fatty acid contents.Furthermore,both C.lentillifera species collected from Hainan and Shandong provinces show more basic nutrients.Therefore,C.lentillifera has important development and application prospects.ZHANG Meijian MA Yurong CHE Xinyi HUANG Zumei CHEN Peng XIA Guanghua ZHAO Meihui 2020Journal of Ocean University of China2020,19,2:8
3FHY3 and FAR1 Integrate Light Signals with the miR156-SPL Module-Mediated Aging Pathway to Regulate Arabidopsis Flowering显示文摘In response to competition for light from their neighbors,shade-intolerant plants flower precociously to ensure reproductive success and survival.However,the molecular mechanisms underlying this key developmental switch are not well understood.Here,we show that a pair of Arabidopsis transcription factors essential for phytochrome A signaling,FAR-RED ELONGATED HYPOCOTYL3(FHY3)and FAR-RED IMPAIRED RESPONSE1(FAR1),regulate flowering time by integrating environmental light signals with the miR156-SPL module-mediated aging pathway.We found that FHY3 and FAR1 directly interact with three flowering-promoting SQUAMOSA-PROMOTER BINDING PROTEIN-LIKE(SPL)transcription factors,SPL3,SPL4,and SPL5,and inhibit their binding to the promoters of several key flowering regulatory genes,including FRUITFUL(FUL),LEAFY(LFY),APETALA1(AP1),and MIR172C,thus downregulating their transcript levels and delaying flowering.Under simulated shade conditions,levels of SPL3/4/5 proteins increase,whereas levels of FHY3 and FAR1 proteins decline,thus releasing SPL3/4/5 from FHY3/FAR1 inhibition to allow activation of FUL,LFY,AP1,and MIR172C and,consequently,early flowering.Taken together,these results unravel a novel mechanism whereby plants regulate flowering time by integrating environmental cues(such as light conditions)and an internal developmental program(the miR156-SPL module-mediated aging pathway).Yurong Xie Qin Zhou Yongping Zhao Quanquan Li Yang Liu Mengdi Ma Baobao Wang Rongxin Shen Zhigang Zheng Haiyang Wang 2020Molecular Plant2020,13,3:8
4Consensus control of stochastic multi-agent systems: a survey显示文摘In this article, we provide a review of the consensus control problem for stochastic multi-agent systems(MASs). Recent advances are surveyed according to the method of occurrence of the stochasticity of the MASs. First, the consensus problem is discussed for MASs, wherein individual agents are corrupted by random noises, i.e., the dynamics of agents involve stochasticity in process and/or measurement equations. Both additive noises and multiplicative noises are surveyed in detail and special attention is paid to the MASs whose dynamics are governed by It?o differential equations. Moreover, particular effort is devoted to presenting the latest progress on the consensus problem for a special type of stochastic MAS with Markovian jump parameters. Subsequently,the relevant research is summarized for MASs with noisy communication environments and stochastic sampling.Further, we provide a systematic review of the consensus problems for MASs whose communication topology varies randomly in the process of data propagation among agents. Finally, conclusions are drawn and several potential future research directions are outlined.Lifeng MA Zidong WANG Qing-Long HAN Yurong LIU 2017Science China(Information Sciences)2017,60,12:5
5Analytic estimation and numerical modeling of actively cooled thermal protection systems with nickel alloys显示文摘Actively cooled thermal protection system has great influence on the engine of a hypersonic vehicle, and it is significant to obtain the thermal and stress distribution in the system. So an analytic estimation and numerical modeling are performed in this paper to investigate the behavior of an actively cooled thermal protection system. The analytic estimation is based on the electric analogy method and finite element analysis(FEA) is applied to the numerical simulation. Temperature and stress distributions are obtained for the actively cooled channel walls with three kinds of nickel alloys with or with no thermal barrier coating(TBC). The temperature of the channel wall with coating has no obvious difference from the one with no coating, but the stress with coating on the channel wall is much smaller than that with no coating. Inconel X-750 has the best characteristics among the three Ni-based materials due to its higher thermal conductivity, lower elasticity module and greater allowable stress. Analytic estimation and numerical modeling results are compared with each other and a reasonable agreement is obtained.Wang Xinzhi He Yurong Zheng Yan Ma Junjun H.

6Structurally tunable characteristics of ionic liquids for optimizing lithium plating/stripping via electrolyte engineering显示文摘Electrolyte chemistry offers the opportunity to regulate the solid electrolyte interphase(SEI) and Li^(+)solvation,which is considered to be crucial to the growth of lithium crystals for safe lithium metal batteries(LMBs).Structurally tunable characteristics of ionic liquids(ILs) from anion type,cationic substituent chain length and cationic substituents,will contribute this field.Here,we explore the influence mechanism of imidazole-based ILs as electrolyte additives on Li+solvation and the formation of SEI.ILs can participate into the formation of efficient SEI,together with cathode electrolyte interphase(CEI).Moreover,ILs can also regulate the sheath structure of Li^(+)solvation,to fasten the kinetics of Li.Furthermore,the imidazole-based cations with long alkyl chain can form an electrostatic shield around newly formed Li nucleus,and suppress further Li plating at this site.Under the optimized condition,the 1-octyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide([OMIm]TFSI) additive shows the best ability to enhance the electrochemical performance,endowing the Li||Li symmetric cell with a stable life(over800 h) at 0.5 mA cm^(-2) and the Li||LiNi_(0.6)Mn_(0.2)Co_(0.2)O_(2)(NMC622) full cell with a high capacity of 141.7 mAh g^(-1) after 200 cycles at 0.5 C.Shihan Qi Jiandong Liu Jian He Huaping Wang Mingguang Wu Daxiong Wu Junda Huang Fang Li Xin Li Yurong Ren Jianmin Ma 2021Journal of Energy Chemistry2021,30,12:2
7Rice(Oryza sativa L.)seedlings enriched with zinc or manganese:Their impacts on cadmium accumulation and expression of related genes显示文摘Cadmium(Cd)contamination in paddy soils means that the rice produced there may be unsafe for human consumption.A hydroponic study was conducted to enrich rice seedlings with zinc(Zn)or manganese(Mn),and the uptake and transport characteristics of Cd in these Zn-and Mn-rich seedlings were subsequently investigated using a greenhouse pot trial.The results showed that hydroponic cultivation in 10-50μmol L^(-1) Zn(ZnSO_(4)·7 H_(2)O)or50-250μmol L^(-1) Mn(MnSO_(4)·H_(2)O)for 30 d had no significant impact on rice growth,while the accumulation of Zn and Mn was 7.31-18.5 and 25.4-47.7 times higher,respectively,than in the control(no Zn or Mn addition).The accumulation of Cd in the Zn-and Mn-rich rice plants was 26.3%-38.6% and 34.4%-44.5% lower than that in the control,respectively,and the translocation factors of Cd from roots to shoots also decreased by 23.3%-41.3% and 25.3%-37.0%,respectively,after transplanting to Cd-contaminated soils.Furthermore,the relative expression levels of OsIRT1(Oryza sativa iron-regulated transporter 1)were downregulated by 40.1%-59.3% and 16.0%-25.9%,respectively,in the Zn-and Mn-rich seedling roots.This downregulation may indicate a possible mechanism contributing to the reductions in Cd absorption.Field experiments confirmed that the Zn-and Mn-rich seedlings produced brown rice(unpolished rice grains)with significantly decreased concentrations of Cd(34.2%-44.4%).This study provides an innovative method for reducing the food safety risks from rice grown on slightly to moderately Cd-contaminated paddy soils.Gaoxiang HUANG Changfeng DING Yibing MA Yurong WANG Zhigao ZHOU Shun'an ZHENG Xingxiang WANG 2021Pedosphere2021,31,6:2
8Electrochemical sensing of ATP with synthetic cyclophane as recognition element显示文摘A new electrochemical sensor for ATP with synthetic cyclophane stably attached onto single-walled carbon nanotubes (SWNTs) as the recognition elements is described. UV-vis and cyclic voltammetric results demonstrate that ATP may interact with the synthetic cyclophane recognition elements to form a stable adduct mainly through electrostatic, π-π stacking and donor-acceptor interactions. Such interactions eventually lead to a decrease in the peak currents of the cyclophane recognition elements attached onto the SWNT electronic transducer, which could be used for electrochemical sensing of ATP. Under the conditions employed here, the ratio of the decrease in the anodic peak current is linear with ATP concentration within a concentration range from 10 to 120 μM with a linear coefficiency of 0.993. This study may offer a new and simple electrochemical approach for effective sensing of ATP.MA YuRong ZHAO Hong YU Ping SU Lei ZHANG DeQing MAO LanQun 2009Science China Chemistry2009,52,6:2
