1Diagenetic fluids evolution and genetic mechanism of tight sandstone gas reservoirs in Upper Triassic Xujiahe Formation in Sichuan Basin, China显示文摘The reservoirs of the Upper Triassic Xujiahe Formation in Sichuan Basin have the characteristics of low compositional maturity, low contents of cements and medium textural maturity. The general physical properties of the reservoirs are poor, with low porosity and low permeability, and there are only a few reservoirs with medium porosity and low permeability in local areas. Based on the diagenetic mineral association, a diagenetic sequence of cements is established: early calcites (or micrite siderites) →first quartz overgrowth→chlorite coatings→dissolution of feldspars and debris→chlorite linings→ second quartz overgrowth (quartz widen or filled in remain intergranular pores and solution pores)→dissolution→third quartz overgrowth (quartz filled in intergranular and intragranular solution pores)→intergrowth (ferro) calcites→dolomites→ferro (calcites) dolomites→later dissolution→veins of quartz and calcites formation. Mechanical compaction is the main factor in making the reservoirs tight in the basin, followed by the second and third quartz overgrowth. In a long-term closed system, only feld-spars and some lithic fragments are dissolved by diagenetic fluids, while intergranular cements such as quartz and calcit are not dissolved and thus have little influence on the porosity of the Xujiahe Formation. This is the third factor that may have kept the sandstones of Xujiahe Formation tight finally. The hydrocarbon was extensively generated from organic materials after the second quartz overgrowth, and selectively entered favorable reservoirs to form tight sandstone gas reservoirs.ZHU RuKai ZOU CaiNeng ZHANG Nai WANG XueSong CHENG Rong LIU LiuHong ZHOU ChuanMin SONG LiHong 2008Science China Earth Sciences2008,51,9:29
2Review on biological degradation of mycotoxins显示文摘The worldwide contamination of feeds and foods with mycotoxins is a significant problem. Mycotoxins pose huge health threat to animals and humans. As well, mycotoxins bring enormous economic losses in food industry and animal husbandry annually. Thus, strategies to eliminate or inactivate mycotoxins in food and feed are urgently needed. Traditional physical and chemical methods have some limitations such as limited efficacy, safety issues, losses in the nutritional value and the palatability of feeds, as well as the expensive equipment required to implement these techniques. Biological degradation of mycotoxins has shown promise because it works under mild, environmentally friendly conditions. Aflatoxin(AF), zearalenone(ZEA) and deoxynivalenol(DON) are considered the most economically important mycotoxins in terms of their high prevalence and significant negative effects on animal performance.Therefore, this review will comprehensively describe the biological degradation of AF, ZEA and DON by microorganisms(including fungi and bacteria) and specific enzymes isolated from microbial systems that can convert mycotoxins with varied efficiency to non-or less toxic products. Finally, some strategies and advices on existing difficulties of biodegradation research are also briefly proposed in this paper.Cheng Ji Yu Fan Lihong Zhao 2016Animal Nutrition2016,,3:24
3Occurrence of mycotoxins in feed ingredients and complete feeds obtained from the Beijing region of China显示文摘Background:The current study was carried out to provide a reference for the control of mycotoxin contamination in feed ingredients and complete feeds for swine.Methods:A total of 55 feed ingredients,including 14 corn,13 wheat bran,11 soybean meal and 17 dried distillers grains with solubles(DDGS) as well as 76 complete swine feeds including 7 creep feeds,14 starter feeds,14 grower feeds,18 grower-finisher feeds,10 gestating sow feeds,and 13 lactating sow feeds were randomly collected from15 swine farms located in the Beijing region of China from July to August 2011.Immunoaffinity clean-up,using High-Performance Liquid Chromatography(HPLC) in combination with UV or Fluorescence Detection,was used for quantitative analysis of aflatoxin B,(AFB,),deoxynivalenol(DON),zearalenone(ZEA) and ochratoxin A(OTA) in the ingredients and complete feeds.Results:DON and ZEA were the most prevalent mycotoxins found.DON was detected at percentages of 93,92,54,100 and 97%with a mean level of 1.01,0.44,0.05,1.36 and 0.65 ppm in the samples of corn,wheat bran,soybean meal,DDGS and complete feeds,respectively.The detected percentages of ZEA were 100,100,54,100 and 100 with mean levels of 109.1,14.9,9.2,882.7 and 58.9 ppb in the same samples.In the wheat bran and soybean meal samples,the content of all four mycotoxins were below the maximum limits set by Chinese regulations while the percentage of samples that exceeded regulatory limits were 7,57 and 7%for corn,and 7,14 and 3%for the complete feeds for AFB,,DON and OTA respectively.DDGS showed the most serious mycotoxin contamination and the percentage of samples that exceeded regulatory limits were 6,88 and 41%,for AFB,,DON and ZEA,respectively.Conclusions:This paper is the first to present data on the natural occurrence of AFB,,DON,ZEA and OTA in ingredients and complete feeds obtained from swine farms in China's Beijing region.The data shows that feed ingredients and complete swine feeds obtained from these farms are most often contaminated with DON followed by contamination with AFB,and ZEA.Xiaoying Li Lihong Zhao Yu Fan Yaxiong Jia Lei Sun Shanshan Ma Cheng Ji Qiugang Ma Jianyun Zhang 2014Journal of Animal Science and Biotechnology2014,5,4:7
4Alleviation of mycotoxin biodegradation agent on zearalenone and deoxynivalenol toxicosis in immature gilts显示文摘Background: The current study was carried out to evaluate the effects of mycotoxin biodegradation agent(MBA, composed of Bacillus subtilis ANSB01 G and Devosia sp. ANSB714) on relieving zearalenone(ZEA) and deoxynivalenol(DON) toxicosis in immature gilts.Methods: A total of forty pre-pubertal female gilts(61.42 ± 1.18 kg) were randomly allocated to four diet treatments: CO(positive control); MO(negative control, ZEA 596.86 μg/kg feed and DON 796 μg/kg feed);COA(CO + 2 g MBA/kg feed); MOA(MO + 2 g MBA/kg feed). Each treatment contained 10 replicates with 1 gilt per replicate. Gilts were housed in an environmentally controlled room with the partially slatted floor.Results: During the entire experimental period of 28 d, average daily gain(ADG) and average daily feed intake(ADFI)of gilts in MO group was significantly reduced compared with those in CO group. The vulva size of gilts was significantly higher in MO group than CO group. In addition, significant increases in the plasma levels of Ig A,Ig G, IL-8, IL-10 and PRL were determined in MO group compared with that in CO group. ZEA and DON in the diet upregulated apoptotic caspase-3 in ovaries and uteri, along with down-regulated the anti-apoptotic protein Bcl-2 in ovaries. The supplementation of MBA into diets co-contaminated with ZEA and DON significantly increased ADG, decreased the vulva sizes, reduced the levels of Ig G, IL-8 and PRL in plasma, and regulated apoptosis in ovaries and uteri of gilts.Conclusions: The present results indicated that feeding diet contaminated with ZEA and DON simultaneously(596.86 μg/kg + 796 μg/kg) had detrimental effects on growth performance, plasma immune function and reproductive status of gilts. And MBA could reduce the negative impacts of these two toxins, believed as a promising feed additive for mitigating toxicosis of ZEA and DON at low levels in gilts.Donghui Shi Jianchuan Zhou Lihong Zhao Xiaoping Rong Yu Fan Humera Hamid Wenqiang Li Cheng Ji Qiugang Ma 2018Journal of Animal Science and Biotechnology2018,9,3:7
5Hard state of the urban canopy layer turbulence and its self-similar multiplicative cascade models显示文摘It is found by experiment that under the thermal convection condition, the temperature fluctuation in the urban canopy layer turbulence has the hard state character, and the temperature difference between two points has the exponential probability density function distribution. At the same time, the turbulent energy dissipation rate fits the log-normal distribution, and is in accord with the hypothesis proposed by Kolmogorov in 1962 and lots of reported experimental results. In this paper, the scaling law of hard state temperature n order structure function is educed by the self-similar multiplicative cascade models. The theory formula is Sn = n/3μ{n(n+6)/72+[2lnn!-nln2]/2ln6}, and μ Is intermittent exponent. The formula can fit the experimental results up to order 8 exponents, is superior to the predictions by the Kolmogorov theory, the β And log-normal model.HU Fei CHENG Xueling ZHAO Songnian QUAN Lihong 2005Science China Earth Sciences2005,48,z2:4
6Lipid-albumin nanoassemblies co-loaded with borneol and paclitaxel for intracellular drug delivery to C6 glioma cells with P-gp inhibition and its tumor targeting显示文摘Successful chemotherapy with paclitaxel(PTX)is impeded by multidrug resistance(MDR)in tumor cells.In this study,lipid-albumin nanoassemblies co-loaded with borneol and paclitaxel(BOR/PTX LANs)were prepared to circumvent MDR in C6 glioma cells.The physiochemical properties including particle size,encapsulation efficiency and morphology were evaluated in vitro.Quantitative and qualitative investigations of cellular uptake were carried out in C6 glioma cells.The cytotoxicity of the BOR/PTX LANs was determined by MTT assay.After that,the tumor targeting was also evaluated in C6 glioma bearing mice by in vivo imaging analysis.BOR/PTX LANs have a higher entrapment efficiency(90.4±1.2%),small particle size(107.5±3.2 nm),narrow distribution(P.I.=0.171±0.02).The cellular uptake of PTX was significantly increased by BOR/PTX LANs compared with paclitaxel loaded lipidalbumin nanoassemblies(PTX LANs)in quantitative research.The result was further confirmed by confocal laser scanning microscopy qualitatively.The cellular uptake was energy-,timeand concentration-dependent,and clathrin-and endosome/lysosome-associated pathways were involved.The BOR/PTX LANs displayed a higher cytotoxicity agaist C6 glioma cells in comparion with PTX LANs and Taxol.Moreover,the encapsulation of BOR in LANs obviously increased the accumulation of the drug in tumor tissues,demonstrating the tumor targeted ability of BOR/PTX LANs.These results indicated that BOR/PTX LANs could overcome MDR by combination of drug delivery systems and P-gp inhibition,and shown the potential for treatment of gliomas.Bo Tang Guihua Fang Ying Gao Yi Liu Jinwen Liu Meijuan Zou Lihong Wang Gang Cheng 2015Asian Journal of Pharmaceutical Sciences2015,10,5:4
7Impact effects on fused quartz glass by ground simulating hypervelocity space debris显示文摘The optical attenuation of fused silica glass impacted by high-speed micro-particle was studied.The high-speed impact test was carried out using a laser-driven flyer system which accelerated 16 ?m-thick flyer to high speed of 3.7 km s?1.Scanning electron microscopy and optical microscopy were used to characterize the damage morphology of the impacted surface.The transmittance of the impacted glass samples was measured by means of UV/VIS double beam spectrophotometer.It was found that the transmittance of the impact region decreased due to the formation of structural defects such as crater,ejecta and micro-crack on the surface.A mathematic formula was established to explain the relationship between glass optical properties and the damaged modes,which aids to describe optical degradation and design long life optical equipments used in spacecrafts under space particles environment.SONG LiHong WEI Qiang BAI Yu GAO Cheng 2013Chinese Science Bulletin2013,58,7:4
8Focusing light into scattering media with ultrasound-induced field perturbation显示文摘Focusing light into scattering media,although challenging,is highly desirable in many realms.With the invention of time-reversed ultrasonically encoded(TRUE)optical focusing,acousto-optic modulation was demonstrated as a promising guidestar mechanism for achieving noninvasive and addressable optical focusing into scattering media.Here,we report a new ultrasound-assisted technique,ultrasound-induced field perturbation optical focusing,abbreviated as UFP.Unlike in conventional TRUE optical focusing,where only the weak frequency-shifted first-order diffracted photons due to acousto-optic modulation are useful,here UFP leverages the brighter zeroth-order photons diffracted by an ultrasonic guidestar as information carriers to guide optical focusing.We find that the zeroth-order diffracted photons,although not frequency-shifted,do have a field perturbation caused by the existence of the ultrasonic guidestar.By detecting and time-reversing the differential field of the frequency-unshifted photons when the ultrasound is alternately ON and OFF,we can focus light to the position where the field perturbation occurs inside the scattering medium.We demonstrate here that UFP optical focusing has superior performance to conventional TRUE optical focusing,which benefits from the more intense zeroth-order photons.We further show that UFP optical focusing can be easily and flexibly developed into double-shot realization or even single-shot realization,which is desirable for high-speed wavefront shaping.This new method upsets conventional thinking on the utility of an ultrasonic guidestar and broadens the horizon of light control in scattering media.We hope that it provides a more efficient and flexible mechanism for implementing ultrasound-guided wavefront shaping.Zhongtao Cheng Lihong V.Wang 2021Light(Science & Applications)2021,10,9:3
9Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis.Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng 2021National Science Review2021,8,3:3
10The self-assembled nanoparticle-based trimeric RBD mRNA vaccine elicits robust and durable protective immunity against SARS-CoV-2 in mice显示文摘As COVID-19 continues to spread rapidly worldwide and variants continue to emerge,the development and deployment of safe and effective vaccines are urgently needed.Here,we developed an mRNA vaccine based on the trimeric receptor-binding domain(RBD)of the SARS-CoV-2 spike(S)protein fused to ferritin-formed nanoparticles(TF-RBD).Compared to the trimeric form of the RBD mRNA vaccine(T-RBD),TF-RBD delivered intramuscularly elicited robust and durable humoral immunity as well as a Th 1-biased cellular response.After further challenge with live SARS-CoV-2,immunization with a two-shot low-dose regimen of TF-RBD provided adequate protection in hACE2-transduced mice.In addition,the mRNA template of TF-RBD was easily and quickly engineered into a variant vaccine to address SARS-CoV-2 mutations.The TF-RBD multivalent vaccine produced broad-spectrum neutralizing antibodies against Alpha(B.1.1.7)and Beta(B.1.351)variants.This mRNA vaccine based on the encoded self-assembled nanoparticle-based trimer RBD provides a referenee for the design of mRNA vaccines targeting SARS-CoV-2.Wenqiang Sun Lihong He He Zhang Xiaodong Tian Zhihua Bai Lei Sun Limin Yang Xiaojuan Jia Yuhai Bi Tingrong Luo Gong Cheng Wenhui Fan Wenjun Liu Jing Li 2021Signal Transduction and Targeted Therapy2021,6,10:3

12Synthesis, spectral properties of aluminum polymeric phthalocyanine carboxyl with low aggregation in aqueous solution显示文摘A water soluble poly-[tetrakis-(2,3-dicarboxylate phenoxy) methyl methan] aluminum phthalocyanine (AlPPc.(COOH)x) has been synthesized from the cyclization of tetranuclear phthalonitrile and successive hydrolysis of cyano in alkaline solution. The absorption spectra showed low aggregation of this compound in pH 9.18 buffer than that of existing water soluble phthalocyanine compounds. With the addition of Triton X 100, an enhancement of fluorescence emission with quantum yield from 0.4 to 0.83 was observed; contrarily, it was thoroughly quenched by the addition of CATB in suit. A longer life time of singlet state was also detected in presence of Triton X 100. The result indicates that AlPPc.(COOH)x is desired to investigate in fluorescent probe or in fluorescence imaging diagnose.ZHAO Peng NIU LiHong ZHONG Cheng DONG SiDa ZHANG FuShi 2008Chinese Science Bulletin2008,53,20:1

15Zearalenone toxicosis on reproduction as estrogen receptor selective modulator and alleviation of zearalenone biodegradative agent in pregnant sows显示文摘Background:Zearalenone(ZEA)is a resorcylic acid lactone derivative derived from various Fusarium species that are widely found in food and feeds.The molecular structure of ZEA resembles that of the mammalian hormone 17β-oestradiol,thus zearalenone and its metabolites are known to compete with endogenous hormones for estrogen receptors binding sites and to activate transcription of oestrogen-responsive genes.However,the effect of long-term low-dose ZEA exposure on the reproductive response to Bacillus subtilis ANSB01G culture for first-parity gilts has not yet been investigated.This study was conducted to investigate the toxic effects of ZEA as an estrogen receptor selective modulator and the alleviating effects of Bacillus subtilis ANSB01G cultures as ZEA biodegraders in pregnant sows during their first parity.Results:A total of 80 first-parity gilts(Yorkshire×Landrace)were randomly assigned to four dietary treatments during gestation:CO(positive control);MO(negative control,246μg ZEA/kg diet);COA(CO+B.subtilis ANSB01G culture with 2×10^(9)CFU/kg diet);MOA(MO+B.subtilis ANSB01G culture with 2×10^(9)CFU/kg diet).There were 20 replications per treatment with one gilt per replicate.Feeding low-dose ZEA naturally contaminated diets disordered most of reproductive hormones secretion and affected estrogen receptor-αand estrogen receptor-βconcentrations in serum and specific organs and led to moderate histopathological changes of gilts,but did not cause significant detrimental effects on reproductive performance.The addition of Bacillus subtilis ANSB01G culture to the diet can effectively relieve the competence of ZEA to estrogen receptor and the disturbance of reproductive hormones secretion,and then ameliorate toxicosis of ZEA in gilts.Conclusions:Collectively,our study investigated the effects of feeding low-dose ZEA on reproduction in pregnant sows during their first parity.Feeding low-dose ZEA could modulate estrogen receptor-αand-βconcentrations in specific organs,cause disturbance of reproductive hormones and vulva swelling,and damage organ histopathology and up-regulate apoptosis in sow models.Diet with Bacillus subtilis ANSB01G alleviated negative effects of the ZEA on gilts to some extent.Jianchuan Zhou Lihong Zhao Shimeng Huang Qingxiu Liu Xiang Ao Yuanpei Lei Cheng Ji Qiugang Ma 2022Journal of Animal Science and Biotechnology2022,13,4:1

18A comparison of H^+-restacked nanosheets and nanoscrolls derived from K_4Nb_6O_(17) for visible-light degradation of dyes显示文摘H+-restacked nanosheets and nanoscrolls peeled from K4Nb6O17display different structures and surface characters. The two restacked samples with increased surface areas have an amazing visible-light response for the photodegradation of dyes, which is superior to commercial TiO2(P25) and Nb2O5. By comparison, H+/nanosheets have a relatively faster photodegradation rate originated from large and smooth basal plane.The work reveals that dye adsorbed on the unfolded nanosheets can effectively harvest sunlight. Due to facile preparation, low-cost and high photocatalytic efficiency, H+/nanosheets and H+/nanoscrolls might be used for the visible light-driven degradation of organic dyes as a substitute for TiO2in industry.Chenhui Hu Lihong Zhang Liyuan Cheng Jing Chen Wenhua Hou Weiping Ding 2014Journal of Energy Chemistry2014,23,2:1
19A linked data-based approach for clinical treatment selecting support显示文摘Treatment plan selection is a complex process because it sometimes needs sufficient experience and clinical information.Nowadays it is even harder for doctors to select an appropriate treatment plan for certain patients since doctors might encounter difficulties in obtaining the right information and analyzing the diverse clinical data.In order to improve the effectiveness of clinical decision making in complicated information system environments,we first propose a linked data-based approach for treatment plan selection.The approach integrates the patients’clinical records in hospitals with open linked data sources out of hospitals.Then,based on the linked data net,treatment plan selection is carried on aided by similar historical therapy cases.Finally,we reorganize the electronic medical records of 97 colon cancer patients using the linked data model and count the similarity of these records to help treatment selecting.The experiment shows the usability of our method in supporting clinical decisions.Lihong Jiang Ling Li Hongming Cai Hua Liu Jingyuan Hu Cheng Xie 2014Journal of Management Analytics2014,1,4:1
