1Cell membrane-based nanoparticles: a new biomimetic platform for tumor diagnosis and treatment显示文摘Taking inspiration from nature, the biomimetic concept has been integrated into drug delivery systems in cancer therapy. Disguised with cell membranes, the nanoparticles can acquire various functions of natural cells. The cell membrane-coating technology has pushed the limits of common nano-systems(fast elimination in circulation) to more effectively navigate within the body. Moreover, because of the various functional molecules on the surface, cell membrane-based nanoparticles(CMBNPs) are capable of interacting with the complex biological microenvironment of the tumor. Various sources of cell membranes have been explored to camouflage CMBNPs and different tumor-targeting strategies have been developed to enhance the anti-tumor drug delivery therapy. In this review article we highlight the most recent advances in CMBNP-based cancer targeting systems and address the challenges and opportunities in this field.Ruixiang Li Yuwei He Shuya Zhang Jing Qin Jianxin Wang 2018Acta Pharmaceutica Sinica B2018,8,1:36
2Effect of temperature,salinity and irradiance on growth and photosynthesis of Ulva prolifera显示文摘Intensive Pyropia aquaculture in the coast of southwestern Yellow Sea and its subsequent waste, including disposed Ulva prolifera, was speculated to be one of the major sources for the large-scale green tide proceeding in the Yellow Sea since 2007. It was, however, unclear how the detached U. prolifera responded and resumed growing after they detached from its original habitat. In this study, we investigated the growth and photosynthetic response of the detached U. prolifera to various temperature, salinity and irradiance in the laboratory. The photosynthetic rate of the detached U. prolifera was significantly higher at moderate temperature levels(14–27°C)and high salinity(26–32), with optimum at 23°C and 32. Both low(<14°C) and highest temperature(40°C), as well as low salinity(8) had adverse effects on the photosynthesis. Compared with the other Ulva species, U. prolifera showed higher saturated irradiance and no significant photoinhibition at high irradiance, indicating the great tolerance of U. prolifera to the high irradiance. The dense branch and complex structure of floating mats could help protect the thalli and reduce photoinhibition in field. Furthermore, temperature exerted a stronger influence on the growth rate of the detached U. prolifera compared to salinity. Overall, the high growth rate of this detached U. prolifera(10.6%–16.7% d^(–1)) at a wide range of temperature(5–32°C) and salinity(14–32) implied its blooming tendency with fluctuated salinity and temperature during floating. The environmental parameters in the southwestern Yellow Sea at the beginning of green tide were coincident with the optimal conditions for the detached U. prolifera.XIAO Jie ZHANG Xiaohong GAO Chunlei JIANG Meijie LI Ruixiang WANG Zongling LI Yan FAN Shiliang ZHANG Xuelei 2016Acta Oceanologica Sinica2016,35,10:14
3Menthol-modified casein nanoparticles loading 10-hydroxycamptothecin for glioma targeting therapy显示文摘Chemotherapy outcomes for the treatment of glioma remains unsatisfactory due to the inefficient drug transport across the blood–brain barrier(BBB) and insufficient drug accumulation in the tumor region. Although many approaches, including various nanosystems, have been developed to promote the distribution of chemotherapeutics in the brain tumor, the delivery efficiency and the possible damage to the normal brain function still greatly restrict the clinical application of the nanocarriers.Therefore, it is urgent and necessary to discover more safe and effective BBB penetration and gliomatargeting strategies. In the present study, menthol, one of the strongest BBB penetration enhancers screened from traditional Chinese medicine, was conjugated to casein, a natural food protein with brain targeting capability. Then the conjugate self-assembled into the nanoparticles to load anti-cancer drugs.The nanoparticles were characterized to have appropriate size, spheroid shape and high loading drug capacity. Tumor spheroid penetration experiments demonstrated that penetration ability of mentholmodified casein nanoparticles(M-CA-NP) into the tumor were much deeper than that of unmodified nanoparticles. In vivo imaging further verified that M-CA-NPs exhibited higher brain tumor distribution than unmodified nanoparticles. The median survival time of glioma-bearing mice treated with HCPT-MCA-NPs was significantly prolonged than those treated with free HCPT or HCPT-CA-NPs. HE staining ofthe organs indicated the safety of the nanoparticles. Therefore, the study combined the advantages of traditional Chinese medicine strategy with modern delivery technology for brain targeting, and provide a safe and effective approach for glioma therapy.Caifang Gao Jianming Liang Ying Zhu Chengli Ling Zhekang Cheng Ruixiang Li Jing Qin Weigen Lu Jianxin Wang 2019Acta Pharmaceutica Sinica B2019,9,4:12
4Interspecies competition for nutrients between Prorocentrum donghaiense Lu and Skeletonema costatum(Grev.) Cleve in mesocosm experiments显示文摘Three mesocosm experiments were conducted in the East China Sea during blooms of Prorocentrum donghaiense Lu in May of 1998,2002 and 2003 to examine the role of nutrients in the formation of these harmful algae blooms(HABs).The results showed that there was interspecies competition between P.donghaiense and Skeletonema costatum(Grev.) Cleve.The cell number of P.donghaiense and S.costatum accounted for about 85% and 11% of the total cell number of phytoplankton respectively at the beginning of the experiment in May 1998.In May 2002,at the beginning of the experiment,the cell number of P.donghaiense accounted for 55%-66% of the total and S.costatum accounted for 32%-42%.The density of P.donghaiense and S.costatum was over 95% and 1%-5% respectively in May 2003.The results of these three mesocosm experiments showed that the dominant species in this specific community varied with different nutrient availability.Under low-phosphate conditions,the dominant species was P.donghaiense,while S.costatum became dominant in phosphate-replete cases.The average growth rate(1.08 d-1) of S.costatum in exponential growth phase was higher than that(0.39 d-1) of P.donghaiense.In the mesocosm,S.costatum predominated in the mesocosm by its rapid growth.When phosphorus was depleted,the cell number of S.costatum dropped rapidly,while P.donghaiense Lu decreased more slowly.The results from mesocosm experiment may explain why:(1) P.donghaiense bloom usually occurs in May,when phosphate concentration is low;(2) the bloom of S.costatum appears in early spring and summer time,when nutrients increase with increasing Changjiang River(Yangtze River) runoff;(3) the bloom of S.costatum is short and that of P.donghaiense Lu can last more than a month in the East China Sea.ZHU Mingyuan XU Zongjun LI Ruixiang WANG Zongling SHI Xiaoyong 2009Acta Oceanologica Sinica2009,28,1:10
5Drug targeting through platelet membrane-coated nanoparticles for the treatment of rheumatoid arthritis显示文摘The effective drug treatment of rheumatoid arthritis (RA) is hindered by poordelivery efficiency to the diseased site and the serious side effects caused bywide-spread drug distribution. Traditional drug-targeting strategies, such asligand modification, are complex, laborious, and inefficient. Inspired by theintrinsic relationship between platelets and RA, platelet-mimetic nanoparticles(PNPs) were developed for targeted drug delivery in RA. Through plateletreceptor-mediated adhesion, an intact platelet membrane was coated onto poly(lactic-co-glycolic add) nanopartides, endowing the resulting PNPs with variousfunctional receptors. By coating with platelet membranes, the nanoparticleswere stabilized and had a better circulation profile, providing a benefit forpassive targeting. In vitro binding of PNPs to inflamed endothelium, and in vivoaccumulation in joints of a collagen-induced arthritis (CIA) mouse model of RAwere significantly improved via P-selectin and GVPI recognition, indicating thatthe PNPs could effectively target to RA tissues through multiple mechanisms,similar to natural platelets. Moreover, FK506, a model drug, was loaded into thePNPs and used to treat RA. Pharmacodynamic studies demonstrated that theFK506-PNPs had a notable anti-arthritic effect in CIA mice. This study provides anew biomimetic targeting strategy with great potential for the treatment of RA.Yuwei He Ruixiang Li Jianming Liang Ying Zhu Shuya Zhang Zicong Zheng Jing Qin Zhiqing Pang Jianxin Wang 2018Nano Research2018,11,11:9

7Carbon Materials Reinforced Aluminum Composites:A Review显示文摘Carbon materials, including carbon fibers, graphite, diamond, carbon foams, carbon nanotubes, and graphene, are attractive reinforcements for aluminum matrix composites due to their excellent mechanical and/or physical properties as well as light weight. Carbon materials reinforced aluminum(C/Al) composites are promising materials in many areas such as aerospace, thermal management, and automobile. However, there are still some challenging problems that need to be resolved,such as interfacial reactions, low wettability, and anisotropic properties. These problems have limited the use of these composites. This review mainly focuses on the categories, fabrication processes, existing problems and solutions, coatings and interfaces, challenges and opportunities of C/Al composites so as to provide a useful reference for future research.Yu Huang Qiubao Ouyang Di Zhang Jing Zhu Ruixiang Li Hong Yu 2014Acta Metallurgica Sinica(English Letters)2014,27,5:8
8Community structure and controlled factor of attached green algae on the Porphyra yezoensis aquaculture rafts in the Subei Shoal, China显示文摘This study analyzes the community structure, the quantity changes of the algae and the effect of important environmental factors and estimates the total biomass of the attached green algae in the survey areas. The study uses data from surveys of the attached green algae on the Porphyra yezoensis aquaculture rafts and data regarding the environmental factors from October 2010 to April 2011 in the Subei Shoal. The attached green algae on the rafts included Ulva prolifera, Capsosiphon groenlandicus, U. linza, U. intestinalis, U. clathrata, and U. compressa.The biomass changes of the attached green algae exhibited an inverted parabola: the biomass was the highest(14 898 t) in April, and was the second highest(2 034 t) in November; it was lowest in February(only 729 t) and increased sharply from March to April. The species diversity differed significantly among the seasons. In September and October, when the P. yezoensis aquaculture rafts were initially set up, the attached green algae had a high biodiversity, while from December to the next February, a variety of green algae species coexisted on the rafts, although the biomass was low, and from March to April, as the biomass increased sharply, the species diversity dropped to the minimum. During this time, C. groenlandicus was apparently dominant with the maximum biomass proportion up to 80%, while the U. prolifera proportion increased exponentially to 20% to 40%.The water temperature had a direct regulating effect on the biomass and the species succession of the attached green algae. The estimation of the community dynamics and the biomass of the green algae provided the evidence needed to track the origin of the large-scale green tide in the southern Yellow Sea.LI Yan XIAO Jie DING Lanping WANG Zongling SONG Wei FANG Song FAN Shiliang LI Ruixiang ZHANG Xuelei 2015Acta Oceanologica Sinica2015,34,8:6
9A new distinct geminivirus causes soybean stay-green disease显示文摘Dear Editor,Plant viruses make up almost half of the plant disease-causing pathogens,affecting crop yields and the global economy(Savary et al.,2019).Soybean(Glycine max)is one of the most valuable legume crops in the world,supplying 25%of the global edible oil and two-thirds of the global concentrated protein for livestock feeding.Recently,the outbreak of soybean stay-green syndrome with delayed leaf senescence(stay-green),flat pods,and increased number of abnormal seeds has swept the soybean production in the Huang-Huai-Hai region of China,resulting in huge yield losses(Xu et al.,2019).This disease has become an epidemic and prominent problem in soybean production and is still expanding its geography,including North America,posing a serious threat to soybean production(Harbach et al.,2016;Zhang et al.,2016;Li et al.,2019).However,the cause of soybean stay-green syndrome remains obscure.Ruixiang Cheng Ruoxin Mei Rong Yan Hongyu Chen Dan Miao Lina Cai Jiayi Fan Gairu Li Ran Xu Weiguo Lu Yu Gao Wenwu Ye Shuo Su Tianfu Han Junyi Gai Yuanchao Wang Xiaorong Tao Yi Xu 2022Molecular Plant2022,15,6:6
10Nozzle test system for droplet deposition characteristics of orchard air-assisted sprayer and its application显示文摘In order to obtain nozzle droplet deposition characteristics for sprayer mechanical design and variable spraying control algorithms,a nozzle droplet deposition characteristics test system for air-assisted spraying was designed.The test system can supply a stable wind site with precisely controlled air speed whose speed control ranges from 2 m/s to 16 m/s with maximum relative error of 4.5%.It can spray out a certain amount of liquid pesticide with adjustable spraying pressure which can be controlled with high precision while the maximum relative error is only 1.33%.The distribution of droplet deposition can be collected and measured by using the acquisition device and a pesticide deposition optical measurement system.The experiment of two-dimensional nozzle flow measurement was carried out.The results show that nozzle flow distribution is uniform and symmetric with“double-hump”shape in the spray range.Multi-nozzle overlapped droplet deposition ranges from 85%to 116%relative to the average.The nozzle droplet deposition experiment was completed.The experiment results show that in air-assisted spraying,the higher the wind speed,the less droplet deposition is affected by gravity.When the wind speed is higher than 12 m/s and spraying distance is 0.80 m,droplet deposition is concentrated on the originally designated point and hardly affected by gravity.The horizontal spray width becomes smaller with higher wind speed.When the wind speed is high,it can be considered that nozzle deposition only focuses on the nozzle center,if the position requirement is not very high in orchard spraying.Zhai Changyuan Zhao Chunjiang Wang Xiu Li Wei Li Wei Zhu Ruixiang 2014International Journal of Agricultural and Biological Engineering2014,7,2:4
11The application and progress of bioelectrochemical systems (BESs) in soil remediation: A review显示文摘Soil pollution endangers human health and ecological balance,which is why finding a highly efficient way to deal with pollutants is necessary.Biological method is an environmentally friendly treatment method.Bioelectrochemical systems(BESs),which combine electrochemistry with biological methods,have been widely used to remediate polluted environments,including wastewater,sludge,sediment,and soil.In BESs,redox reactions occur on electrodes with electroactive bacteria,which convert pollutants into low-polluting or nonpolluting substances.With BESs being a promising technology in the remediation field,the decontamination mechanisms and applications in soil conducted by BESs have attracted much attention.Therefore,to better understand the research progress of BESs,this paper mainly summarizes the mechanism of different classified BESs.The applications of microbial fuel cells(MFCs)in four pollutants(petroleum,heavy metals,pesticides,antibiotics)and the possible applications of microbial electrolysis cells(MECs)in soil are discussed.The main problems in BESs and possible future development directions are also evaluated.Tian Li Ruixiang Li Qixing Zhou 2021Green Energy & Environment2021,6,1:4

14The Distribution of Green Algal Micro-Propagules and Macroalgae at the Early Stage of Green Tide in the Coastal Area of South Jiangsu Province in 2014显示文摘An integrated investigation was carried out during late April to late May of 2014 in the coastal area of South Jiangsu Province to understand the early development of green tide in the Yellow Sea and discover the temporal and spatial distribution of green algal micro-propagules and macroalgae at the early stage of green tide. The results showed that green algal micro-propagules distributed in all stations from late April to late May, and micro-propagules of high density(> 300 ind. L^(-1)) concentrated in the adjacent Porphyra aquaculture area. Floating macroalgae were initially observed in the northern survey areas, and increased gradually. The dominant species was U. prolifera in the floating macroalgae, ranging between 90% and 100%. The seawater surface temperature and salinity in the above mentioned time period were suitable for the growth of macroalgae. This work can help government to strengthen management to reduce the blooms of macroalgae in the coastal area of South Jiangsu Province and also facilitate the decision-making for managers at the early stage of green tide.LIU Xiangqing WANG Zongling FAN Shiliang ZHANG Xuelei LI Ruixiang LI Yan 2017Journal of Ocean University of China2017,16,1:3
15Structure and seasonal variability of fronts in the Southeast Indian Ocean along sections from Fremantle, Australia to Antarctic Zhongshan Station显示文摘Four sections of expendable conductivity-temperature-depth(XCTD) profiles from Fremantle, Australia to Antarctic Zhongshan Station and Moderate Resolution Imaging Spectroradiometer-Aquarius(MODIS-A) sea surface temperature(SST) products were used to study the structure and seasonal variability of Southeast Indian Ocean fronts. Water mass analysis showed that surface water masses in the Southeast Indian Ocean were less salty in March than in November. Compared with November, the subtropical front(STF) moved southward about one degree of latitude in March, whereas seasonal variability of the subantarctic front(SAF) and polar front(PF) locations was not obvious. In March, the saline front moved northward about two degrees of latitude relative to the thermal front in the upper 100 m at the SAF, which was the northern boundary of subAntarctic surface water(SASW). Analysis of climatological SST gradients from the satellite data showed that regions of enhanced sea surface temperature(SST) gradients were collocated with frontal locations identified with the XCTD data using water mass criteria. The surface expression of the PF identified by the SST gradient was further south by about one degree of latitude relative to the subsurface expression of the PF identified by the northern boundary of cold water.YANG Wei GAO Libao LI Ruixiang LIU Changjian YAN Jinhui 2016Advances in Polar Science2016,27,1:2
16The morphological identification of Protoperidinium(Peridiniales, Dinophyceae) species on the coasts of China显示文摘The classification and identification for Protoperidinium species are the most difficult work during its taxonomic study. In this research, taxonomic status of Protoperidinium was clarified by tracing its taxonomic history, 23 species belong to genus Protoperidinium on the coasts of China were preliminarily identified, and morphological description and plate patterns were given for each species. The key differences of similar species were also discussed in this study, we believe that P. oceanicum and P. murry, P. tumidum and P. fatulipes, P. globules and P.majus are separate species; P. diabolum should be treated as the valid name instead of the reported names Peridinium globosum or Peridinium longipes; the taxonomic relationship between P. punctulatum and P.subinerme requires further study.LI Ruixiang PAN Yulong SUN Huiying LI Yan MA Xin WANG Yan 2016Acta Oceanologica Sinica2016,35,4:2
17Numerical experiments of HAB inducement in Qingdao adjacent coastal area显示文摘A three-dimension ecological dynamic model was established to numerically study the relationship of HAB and environmental conditions.The numerical experiments showed that the growth of diatom,the dominant HAB specie,was mainly restricted by phosphate and silicate.If the concentrations of phosphate and silicate reach 17-25 μg/L and 300-375 μg/L respectively,the water is in a state of eutrophication.When phosphate and silicate up to 26-32 μg/L and 350-500 μg/L respectively,HAB could be induced.The major regions of HAB occurrence are Jiaozhou Bay mouth,coastal bays,and coastal area from Maidao to Shilaoren.To avoid HAB occurrence,concentration of phosphate and silicate should not exceed 17-20 μg/L and 300 μg/L as a whole.Reasonable control of pollutant discharge is a key point to prevent water eutrophication and HAB occurrence.LIU Xuehai LI Ruixiang YUAN Yeli 2010Acta Oceanologica Sinica2010,29,5:2
