2Influence of torrefaction pretreatment on biomass gasification technology显示文摘Torrefaction is a slow pyrolysis process that is carried out in the relatively low temperature range of 220-300°C.The influence of torrefaction as a pretreatment on biomass gasification technology was investigated using a bench-scale torrefaction unit,a bench-scale laminar entrained-flow gasifier,and the analysis techniques TGA-FTIR and low temperature nitrogen adsorption.A series of experiments were performed to examine the characteristics of the torrefaction process,the properties of torrefaction products,and the effects of torrefaction on gas composition,cold gas efficiency and gasification efficiency.The results showed that during the torrefaction process the moisture content of biomass were reduced,and the wood fiber structure of the material was destroyed.This was beneficial to storage,transport and subsequent treatments of biomass in large scale.For solid products,torrefaction increased the energy density,decreased the oxygen/carbon ratio,and created a more complex pore structure.These improved the syngas quality and cold gas efficiency.Combustible gases accounted for about 50% of non-condensable gaseous torrefaction products.Effective use of the torrefaction gases can save energy and improve efficiency.Overall,biomass torrefaction technology has good application prospects in gasification processes.CHEN Qing ZHOU JinSong LIU BingJun MEI QinFeng LUO ZhongYang 2011Chinese Science Bulletin2011,56,14:6
3Rolling up MXene sheets into scrolls to promote their anode performance in lithium-ion batteries显示文摘Although Ti3 C2 MXene sheets have attracted extensive attention in lithium-ion storage techniques,their restacking makes against and even hinders the Li ions diffusion within them,thereby decreasing the capacity as well as rate performance of conventional MXene anode.Here,for the first time,we roll up the Ti3 C2 Tx sheets into scrolls with unclosed topological structure and the interlayer galleries to alleviate the restacking problem.Thus,Ti3 C2 Tx scrolls as anode materials in lithium-ion batteries(LIBs)have higher capacity and better rate performance than Ti3 C2 Tx sheets.On the bases of these,high-capacity silicon nanoparticles are added during the rolling process to in-situ produce Ti3 C2 Tx/Si composite scrolls.The addition of 10%silicon nanoparticles shows the best overall improvement among capacity,rate capability and cyclic stability for Ti3 C2 Tx scrolls.Jianing Meng Fangfang Zhang Li Zhang Lingyang Liu Jiangtao Chen Bingjun Yang Xingbin Yan 2020Journal of Energy Chemistry2020,29,7:4
4Soybean hairy roots produced in vitro by Agrobacterium rhizogenes-mediated transformation显示文摘Soybean is one of the world's most important oil and protein crops. Efficient transformation is a key factor for the improvement of soybean by genetic modification. We describe an optimized protocol for the Agrobacterium rhizogenes-mediated transformation of soybean and the induction of hairy root development in vitro. Cotyledons with 0.5-cm hypocotyls were cut from 5-day-old seedlings and used as explants. After infection and co-cultivation,hairy roots were produced in induction culture medium after 10–12 days. Using this method, 90%–99% of the infected explants of five different cultivars produced hairy roots within one month. Observations using reporter constructs showed that 30%–60% of the hairy roots induced were transformed. Based on high transformation efficiency and short transformation period, this method represents an efficient and rapid platform for study of soybean gene function.Li Chen Yupeng Cai Xiujie Liu Chen Guo Shi Sun Cunxiang Wu Bingjun Jiang Tianfu Han Wensheng Hou 2018The Crop Journal2018,6,2:4
5High-throughput sequencing of 16S r RNA amplicons characterizes gut microbiota shift of juvenile sea cucumber Apostichopus japonicus feeding with three antibiotics显示文摘Sea cucumber Apostichopus japonicus is an important marine economic species in Asian countries due to its profound nutritional and medicinal value. So far, with the rapid development of intensifi ed artifi cial aquaculture of sea cucumbers, the use of antibiotics is still an inexpensive and dispensable way to treat pathogenic infections, especially during the nursery phase. However, there is little information on the eff ects of antibiotics on the intestinal microbiota of sea cucumber. Therefore an Illumina based sequencing method was used to examine the intestinal bacterial composition of juvenile A . japonicas following diets with three typical antibiotics (tetracycline, erythromycin, and norfl oxacin) under 15, 30, and 45 d. The fi ndings reveal that diff erent antibiotics have distinct eff ects on the growth performance of juvenile sea cucumbers. However, the richness and diversity of microbiota were barely aff ected by antibiotics but the community composition alterations indicated that the three antibiotics exhibited their respective patterns of reshaping the intestinal bacteria of juvenile sea cucumbers. In common, the abundance of some sensitive genera with helpful functions, such as Thalassotalea , Shewanella , Sulfi tobacter , and Halomonas decreased signifi cantly with exposure to antibiotics and the abundance of multiple potential pathogenic- and suspected antibiotic-resistant microorganisms like Arcobacter , Leucothrix , and Clostridium_sensu_stricto_1 was found increased signifi cantly in the antibiotic groups. These results suggest that low doses of antibiotics could aff ect the composition of the intestinal microbiota of sea cucumbers and might increase the risk of infection of the hosts. This study could help us to explore how antibacterial compounds modify the gut microbiota of sea cucumbers and provide theoretical guidance in hatchery management by scientifi c antibiotic use in sea cucumber mariculture.ZHAO Ye WANG Qing LIU Hui LI Bingjun ZHANG Hongxia 2019Journal of Oceanology and Limnology2019,37,5:4
6Small changes in the length of diselenide bond-containing linkages exert great influences on the antitumor activity of docetaxel homodimeric prodrug nanoassemblies显示文摘Homodimeric prodrug-based self-assembled nanoparticles,with carrier-free structure and ultrahigh drug loading,is drawing more and more attentions.Homodimeric prodrugs are composed of two drug molecules and a pivotal linkage.The influence of the linkages on the self-assembly,in vivo fate and antitumor activity of homodimeric prodrugs is the focus of research.Herein,three docetaxel(DTX)homodimeric prodrugs are developed using different lengths of diselenide bond-containing linkages.Interestingly,compared with the other two linkages,the longest diselenide bond-containing linkage could facilitate the self-delivery of DTX prodrugs,thus improving the stability,circulation time and tumor targeting of prodrug nanoassemblies.Besides,the extension of linkages reduces the redox-triggered drug release and cytotoxicity of prodrug nanoassemblies in tumor cells.Although the longest diselenide bond-containing prodrug nanoassemblies possessed the lowest cytotoxicity to 4T1 cells,their stable nanostructure maintained intact during circulation and achieve the maximum accumulation of DTX in tumor cells,which finally“turned the table”.Our study illustrates the crucial role of linkages in homodimeric prodrugs,and gives valuable proposal for the development of advanced nano-DDS for cancer treatment.Lingxiao Li Shiyi Zuo Fudan Dong Tian Liu Yanlin Gao Yinxian Yang Xin Wang Jin Sun Bingjun Sun Zhonggui He 2021Asian Journal of Pharmaceutical Sciences2021,16,3:3

8Validation and modification of the AJCC 8th TNM staging system for pancreatic ductal adenocarcinoma in a Chinese cohort:A nationwide pancreas data center analysis显示文摘Objective:To validate the 8 th edition of the American Joint Committee on Cancer(AJCC)staging system for pancreatic ductal adenocarcinoma(PDAC)in a Chinese cohort of radically resected patients and to develop a refined staging system for PDAC.Methods:Data were collected from the China Pancreas Data Center(CPDC)for patients with resected PDAC in 2016 and 2017,and cancer-specific survival(CSS)was evaluated using the Kaplan-Meier method and log-rank test.Univariate and multivariate analyses based on Cox regression were performed to identify prognostic factors.The recursive partitioning analysis(RPA),Kaplan-Meier method,and log-rank test were performed on the training dataset to generate a proposed modification for the 8 th TNM staging system utilizing the preoperative carbohydrate antigen(CA)19-9 level.Validation was performed for both staging systems in the validation cohort.Results:A total of 1,676 PDAC patients were retrieved,and the median CSS was significantly different between the 8 th TNM groupings,with no significant difference in survival between stage IB and IIA.The analysis of T and N stages demonstrated a better prognostic value in the N category.Multivariate analysis showed that the preoperative serum CA19-9 level was the strongest prognostic indicator among all the independent risk factors.All patients with CA19-9>500 U/mL had similar survival,and we proposed a new staging system by combining IB and IIA and stratifying all patients with high CA19-9 into stage III.The modified staging system had a better performance for predicting CSS than the 8 th AJCC staging scheme.Conclusions:The 8 th AJCC staging system for PDAC is suitable for a Chinese cohort of resected patients,and the N category has a better prognostic value than the T category.Our modified staging system has superior accuracy in predicting survival than the 8 th AJCC TNM staging system.Hao Hu Chang Qu Bingjun Tang Weikang Liu Yongsu Ma Yiran Chen Xuehai Xie Yan Zhuang Hongqiao Gao Xiaodong Tian Yinmo Yang 2021Chinese Journal of Cancer Research2021,33,4:3
9Death of Prorocentrum donghaiense May Be a Programmed Autolysis显示文摘Prorocentrum donghaiense,one of the dinoflagellate,has continuously caused large scale red tides along the Chinese coast in recent years. These red tides have brought tremendous loss to the local economy and serious impacts to the local environment. Unfortunately,little was known about the mechanism of the fast appearance and extinction of the red tide caused by this alga. In this study,the full-length cDNA of a caspase encoding gene of P. donghaiense was cloned and characterized,and the transcription of this gene during the senescence of the alga was semi-quantitatively determined. The cDNA was 520 bp in length. It contained a 258 bp open reading frame(ORF) which encoded a peptide of 85 amino acids. The amount of transcripts of the caspase encoding gene increased with the senescence of P. donghaiense and started to decrease gradually when the autolysis of P. donghaiense cells took place. We proposed that the death of P. donghaiense may be a caspase mediated programmed autolysis.YANG Guanpin LIU Yongjian LI Bingjun 2008Journal of Ocean University of China2008,7,3:1
10Conspicuous cruciform silk decorations deflect avian predator attacks显示文摘Although camouflage as an effective antipredator defense strategy is widespread across animals,highly conspicuous color patterning is not uncommon either.Many orb-web spiders adorn their webs with extra bright white silk.These conspicuous decorations are hypothesized to deter predators by warning the presence of sticky webs,camouflaging spiders,acting as a decoy,or intimidating predators by their apparent size.The decorations may also deflect predator attacks from spiders.However,empirical evidence for this deflection function remains limited.Here,we tested this hypothesis using the X-shaped silk cruciform decorations built by females of Argiope minuta.We employed visual modeling to quantify the conspicuousness of spiders and decorations from a perspective of avian predators.Then,we determined actual predation risk on spiders using naïve chicks as predators.Spider bodies and decorations were conspicuous against natural backgrounds to the avian visual systems.Chicks attacked the spider main bodies significantly less frequently on the decorated webs than on the undecorated webs,thus reducing predation risk.When both spiders and decorations were present,chicks also attacked the spider main bodies and their legs or decorations,and not randomly:they attacked the legs or decorations sooner and more frequently than they attacked the main bodies,independent of the ratio of the surface area between the decoration and spider size.Despite the increase in detectability,incorporating a conspicuous cruciform decoration to the web effectively defends the spider by diverting the attack toward the decoration or leg,but not by camouflaging or intimidating,thus,supporting the deflection hypothesis.Bingjun WANG Long YU Nina MA Zengtao ZHANG Deyong GONG Rui LIU Daiqin LI Shichang ZHANG 2022Integrative Zoology2022,17,5:1

12Minor change in the length of carbon chain has a great influence on the antitumor effect of paclitaxel-fatty alcohol prodrug nanoassemblies:Small roles,big impacts显示文摘Prodrug-based nanoassembly emerges as a hopeful way for the efficient delivery of antitumor drugs,with carrier-free structure and ultra-high drug loading.Carbon chains are widely used to design self-assembling prodrugs.The impacts of the length of carbon chains on the self-assembly stability,drug delivery efficiency and antitumor effect of prodrugs have not been fully elucidated.Here,three paclitaxel prodrugs were synthesized by conjugating paclitaxel with octanol(C_(8)),decanol(C_(10))or dodecanol(C_(12))through disulfide bond.The three prodrugs could form homogeneous nanoparticles,with over 50%drug loading and redox dual-responsivity.Interestingly,the length extension of carbon chains ameliorates the self-assembly and the colloidal stability of prodrugs,thus improving the drug delivery efficiency.The optimal paclitaxel-dodecanol prodrug nanoassemblies exhibit better antitumor efficacy than Taxol and Abraxane.These findings are meaningful for the rational design of advanced nanomedicines in cancer therapy.Xin Wang Lingxiao Li Danping Wang Shiyi Zuo Tian Liu Fudan Dong Xuanbo Zhang Zhonggui He Bingjun Sun Jin Sun 2022Nano Research2022,15,4:1
13Effect of Metal Additives on Performance of Low-Carbon Magnesia-Carbon Materials显示文摘In this paper,both oxidation and corrosion resistance of low-carbon magnesia-carbon materials containing 4.0wt% graphite with metallic Al and Mg-Al alloy powders as antioxidants were investigated.Meanwhile,the microstructures of samples corroded by slag were observed with optical microscope as well.The test results revealed the properties of oxidation and corrosion resistance of low-carbon magnesia-carbon materials could be improved obviously by adding metal Al powder and Mg-Al alloy powder.The rule of improving oxidation resistance was illegibility when metal Al powder and Mg-Al alloy powder were added together.It was harmful to corrosion resistance by mixed adding metal Al powder and Mg-Al alloy powder into the materials,at the same time,the corrosion resistance would decreased with the increasing of Mg-Al alloy content.The corrosion resistance of samples with 0.5wt% or 3.0wt% Mg-Al alloy was better. The oxidation resistance and corrosion resistance of materials with metal Al or Mg-Al alloy respectively were better than that with mixed metal Al and Mg-Al alloy. As a result, Mg-Al alloy was more suitable for low-carbon composite materials than metal Al as additives.PENG Xiaoyan LI Lin HE Zhiyong LIU Kaiqi WANG Bingjun 2007China's Refractories2007,16,1:1
14Analysis and elimination of tri-band beacon interference with the fluxgate sensors onboard CSES显示文摘High precision magnetometer(HPM)is a magnetic field detection payload onboard China Seismo-Electromagnetic Satellite(CSES),including two fluxgate magnetometers(FGM)and a coupled dark state magnetometer(CDSM).Observations show that FGM appears to be influenced when tri-band beacon(TBB)is powered on and emits electromagnetic waves.The interference phenomenon is further validated based on both in-orbit observation analysis and electromagnetic compatibility(EMC)tests on the ground.A joint correction algorithm based on the least square fitting and first-order difference method according to scalar magnetometer data is proposed to eliminate the interference.The algorithm significantly improves the consistency of HPM data.After correction,the average scalar deviation error could be reduced from 9.0 nT to around 0.7 nT.TONG YuQi CHENG BingJun MIAO YuanQing ZHOU Bin ZHU XingHong YANG YanYan LIU Ji GOU XiaoChen ZHANG YiTeng WANG JinDong LI Lei MAGNES Werner LAMMEGGER Roland POLLINGER Andreas ZEREN Zhima SHEN XuHui 2021Science China(Technological Sciences)2021,64,10:1
15Impact of the amount of PEG on prodrug nanoassemblies for efficient cancer therapy显示文摘PEGylation has been widely used to improve the pharmacokinetic properties of prodrug self-assembled nanoparticles(prodrug-SANPs).However,the impacts of the amount of PEG on the self-assemble stability,cellular uptake,pharmacokinetics,and antitumor efficacy of prodrug-SANPs are still unknown.Herein,selenoether bond bridged docetaxel dimeric prodrug was synthesized as the model prodrug.Five prodrug-SANPs were designed by using different mass ratios of prodrugs to PEG(W_(prodrug)/W_(DSPE-mPEG2000)=10:0,9:1,8:2,7:3 and 6:4),and defined as Pure drug NPs,9:1NPs,8:2NPs,7:3 NPs and 6:4 NPs,respectively.Interestingly,8:2 NPs formed the most compact nanostructure,thus improving the self-assemble stability and pharmacokinetics behavior.In addition,the difference of these prodrug-SANPs in cellular uptake was investigated,and the influence of PEG on cytotoxicity and antitumor efficacy was also clarified in details.The 8:2 NPs exhibited much better antitumor efficacy than other prodrug-SANPs and even commercial product.Our findings demonstrated the pivotal role of the amount of PEG on prodrug-SANPs.Yaqiao Li Lingxiao Li Qianhui Jin Tian Liu Jin Sun Yongjun Wang Zhijun Yang Zhonggui He Bingjun Sun 2022Asian Journal of Pharmaceutical Sciences2022,17,2:1

18Structurally defined tandem-responsive nanoassemblies composed of dipeptide-based photosensitive derivatives and hypoxia-activated camptothecin prodrugs against primary and metastatic breast tumors显示文摘Substantial progress in the use of chemo-photodynamic nano-drug delivery systems(nanoDDS) for the treatment of the malignant breast cancer has been achieved. The inability to customize precise nanostructures, however, has limited the therapeutic efficacy of the prepared nano-DDS to date. Here,we report a structurally defined tandem-responsive chemo-photosensitive co-nanoassembly to eliminate primary breast tumor and prevent lung metastasis. This both-in-one co-nanoassembly is prepared by assembling a biocompatible photosensitive derivative(pheophorbide-diphenylalanine peptide, PPADA) with a hypoxia-activated camptothecin(CPT) prodrug [(4-nitrophenyl) formate camptothecin, NCPT]. According to computational simulations, the co-assembly nanostructure is not the classical core-shell type, but consists of many small microphase regions. Upon exposure to a 660 nm laser,PPA-DA induce high levels of ROS production to effectively achieve the apoptosis of normoxic cancer cells. Subsequently, the hypoxia-activated N-CPT and CPT spatially penetrate deep into the hypoxic region of the tumor and suppress hypoxia-induced tumor metastasis. Benefiting from the rational design of the chemo-photodynamic both-in-one nano-DDS, these nanomedicines exhibit a promising potential in the inhibition of difficult-to-treat breast tumor metastasis in patients with breast cancer.Mengchi Sun Hailun Jiang Tian Liu Xiao Tan Qikun Jiang Bingjun Sun Yulong Zheng Gang Wang Yang Wang Maosheng Cheng Zhonggui He Jin Sun 2022Acta Pharmaceutica Sinica B2022,12,2:1
