1全新世长江泥沙堆积的时空分布及通量估算显示文摘利用长江中下游、河口及口外、浙-闽沿岸陆架6个主要沉积盆地的40个晚第四纪钻孔及其年代学数据和长江口外、陆架的浅地层剖面,计算了全新世不同阶段各沉积盆地的沉积速率,并进行了近7 000年来泥沙堆积通量的估算.研究发现全新世早期距今10 000年至8 000年间长江口下切古河谷是长江泥沙的主要堆积中心,沉积速率可高达15 m/ka.随着海平面上升,全新世中期长江中下游也成为长江泥沙的重要沉积盆地,其中江汉盆地的沉积速率可达10 m/ka.近2 000年来,口外、陆架的堆积呈明显增加趋势,反映长江中下游盆地和河口可容空间日益减小.根据沉积速率估算,距今7 000年来长江中下游堆积泥沙约13 074×10^8t,同期水下三角洲和陆架的泥沙堆积量约为9 470×10^8 t.研究还发现全新世以来有两个异常低沉积速率时期:距今8 000-7 000年期间上述各沉积盆地沉积速率均显著低,未见长江泥沙的沉积中心;距今4 000-2 000年期间长江口呈现低沉积速率.这两次异常的原因推测与海平面、气候波动事件密切相关.王张华 Jingpu Paul Liu 赵宝成 2007古地理学报2007,9,4:9
2Cloned goats (Gapra hircus) from foetal fibroblast cell lines显示文摘Mammalian cloning has been one of the most active research topics in the world. Cioning with in vitro culured foetal fibroblast cells, in comparison with embryonic cells, can be used not only to theoretically study the embryonic or cellular development and differentiation in mammals, but also to utilize the unlimited fibroblast cells to produce large numbers of clonings. The preliminary results are as follows: (i) The division and development of the cloned embryos with embryonic donor cells and goat foetal fibroblast donor cells were 55%, 77% and 35%, 31%, respectively. There is no significant statistical difference between them. (? These studies result in the birth of two cloned goats derived from two 30-day foetal fibroblast celi lines, which are the first cloned mammals from somatic cells in China. This project has established a technological data base for the furture research on adult mammalian somatic cloning and nucleocytoplasmic interactions in animal development, and a novel technique for theWANG Yuge ZOU Xiangang LIU Jie ZHANG Jingpu ZHANG Xuechen LAO Weide DU Miao CHENG Guoxing CHENG Yong CHEN Jianquan ZHANG Suolin XU Shaofu 2000Chinese Science Bulletin2000,45,1:4
3Genetic basis of high level aminoglycoside resistance in Acinetobacter baumannii from Beijing,China显示文摘The objective of this study was to investigate the genetic basis of high level aminoglycoside resistance in Acinetobacter baumannii clinical isolates from Beijing,China.173 A.baumannii clinical isolates from hospitals in Beijing from 2006 to 2009 were first subjected to high level aminoglycoside resistance(HLAR,MIC to gentamicin and amikacin>512 mg/mL)phenotype selection by broth microdilution method.The strains were then subjected to genetic basis analysis by PCR detection of the aminoglycoside modifying enzyme genes(aac(3)-Ⅰ,aac(3)-Ⅱc,aac(60)-Ⅰb,aac(60)-Ⅱ,aph(4)-Ⅰa,aph(30)-Ⅰ,aph(30)-Ⅱb,aph(30)-Ⅲa,aph(30)-Ⅵa,aph(2″)-Ⅰb,aph(2″)-Ⅰc,aph(2″)-Ⅰd,ant(2″)-Ⅰa,ant(3″)-Ⅰand ant(40)-Ⅰa)and the 16S rRNA methylase genes(armA,rmtB and rmtC).Correlation analysis between the presence of aminoglycoside resistance gene and HLAR phenotype were performed by SPSS.Totally 102(58.96%)HLAR isolates were selected.The HLAR rates for year 2006,2007,2008 and 2009 were 52.63%,65.22%,51.11%and 70.83%,respectively.Five modifying enzyme genes(aac(3)-Ⅰ,detection rate of 65.69%;aac(60)-Ⅰb,detection rate of 45.10%;aph(30)-Ⅰ,detection rate of 47.06%;aph(30)-Ⅱb,detection rate of 0.98%;ant(3″)-Ⅰ,detection rate of 95.10%)and one methylase gene(armA,detection rate of 98.04%)were detected in the 102 A.baumannii with aac(3)-Ⅰ+aac(60)-Ⅰ+þant(3″)-Ⅰ+armA(detection rate of 25.49%),aac(3)-Ⅰ+aph(30)-Ⅰ+ant(3″)-Ⅰ+armA(detection rate of 21.57%)and ant(3″)-Ⅰ+armA(detection rate of 12.75%)being the most prevalent gene profiles.The values of chi-square tests showed correlation of armA,ant(3″)-Ⅰ,aac(3)-Ⅰ,aph(30)-Ⅰand aac(60)-Ⅰb with HLAR.armA had significant correlation(contingency coefficient 0.685)and good contingency with HLAR(kappa 0.940).The high rates of HLAR may cause a serious problem for combination therapy of aminoglycoside with β-lactams against A.baumannii infections.As armA was reported to be able to cause high level aminoglycoside resistance to most of the clinical important aminoglycosides(gentamicin,amikacin,tobramycin,etc),the function of aminoglycoside modifying enzyme gene(s)in A.baumannii carrying armA deserves further investigation.Lu Nie Yuemeng Lv Min Yuan Xinxin Hu Tongying Nie Xinyi Yang Guoqing Li Jing Pang Jingpu Zhang Congran Li Xiukun Wang Xuefu You 2014Acta Pharmaceutica Sinica B2014,4,4:3
4Application of a new wind driving force model in soil wind erosion area of northern China显示文摘The shear stress generated by the wind on the land surface is the driving force that results in the wind erosion of the soil.It is an independent factor influencing soil wind erosion.The factors related to wind erosivity,known as submodels,mainly include the weather factor(WF)in revised wind erosion equation(RWEQ),the erosion submodel(ES)in wind erosion prediction system(WEPS),as well as the drift potential(DP)in wind energy environmental assessment.However,the essential factors of WF and ES contain wind,soil characteristics and surface coverings,which therefore results in the interdependence between WF or ES and other factors(e.g.,soil erodible factor)in soil erosion models.Considering that DP is a relative indicator of the wind energy environment and does not have the value of expressing wind to induce shear stress on the surface.Therefore,a new factor is needed to express accurately wind erosivity.Based on the theoretical basis that the soil loss by wind erosion(Q)is proportional to the shear stress of the wind on the soil surface,a new model of wind driving force(WDF)was established,which expresses the potential capacity of wind to drive soil mass in per unit area and a period of time.Through the calculations in the typical area,the WDF,WF and DP are compared and analyzed from the theoretical basis,construction goal,problem-solving ability and typical area application;the spatial distribution of soil wind erosion intensity was concurrently compared with the spatial distributions of the WDF,WF and DP values in the typical area.The results indicate that the WDF is better to reflect the potential capacity of wind erosivity than WF and DP,and that the WDF model is a good model with universal applicability and can be logically incorporated into the soil wind erosion models.ZOU Xueyong LI Huiru LIU Wei WANG Jingpu CHENG Hong WU Xiaoxu ZHANG Chunlai KANG Liqiang 2020Journal of Arid Land2020,12,3:2
5Human iPS Cells Loaded with MnO2-Based Nanoprobes for Photodynamic and Simultaneous Enhanced Immunotherapy Against Cancer显示文摘How to trigger strong anti-tumor immune responses has become a focus for tumor therapy.Here,we report the human-induced pluripotent stem cells(iPSs)to deliver MnO2@Ce6 nanoprobes into tumors for simultaneous photodynamic therapy(PDT)and enhanced immunotherapy.Ce6 photosensitizer was attached on manganese dioxide(MnO2)nanoparticles,and resultant MnO2@Ce6 nanoprobes were delivered into mitomycin-treated iPSs to form iPS-MnO2@Ce6 nanoprobes.The iPS-MnO2@Ce6 actively targeted in vivo tumors,the acidic microenvironment triggered interaction between MnO2 and H2O2,released large quantities of oxygen,alleviated hypoxia in tumor.Upon PDT,singlet oxygen formed,broken iPSs released tumor-shared antigens,which evoked an intensive innate and adaptive immune response against the tumor,improving dendritic cells matured,effector T cells,and natural killer cells were activated.Meanwhile,regulatory T cells were reduced,and then the immune response induced by iPS-MnO2@Ce6 was markedly stronger than the immune reaction induced by MnO2@Ce6(P<0.05).The iPS-MnO2@Ce6 markedly inhibited tumor growth and metastasis and reduced mortality in mice models with tumor.Human iPS s loaded with MnO2-based nanoprobes are a promising strategy for simultaneous PDT and enhanced immunotherapy against tumor and own clinical translational prospect.Yanlei Liu Jingxing Yang Bin Liu Wen Cao Jingpu Zhang Yuming Yang Lijun Ma Jesus Martinez de la Fuente Jie Song Jian Ni Chunfu Zhang Daxiang Cui 2020Nano-Micro Letters2020,12,10:2

15Application of a nuclear localization signal gene in transgene mice显示文摘Efficient gene transfer by cytoplasm co-injec-tion will offer a powerful means for transgenic animals. Us-ing co-injection in cytoplasm, two independent gene con-structs, including bovine a-s1-casein-hG-CSF and a mammal expression vector expressing a nuclear localization signal (mNLS), were introduced into fertilized mouse eggs. The target gene construct was docked into host nucleus probably by the nuclear localization signal. Transgene mice have been obtained at 58% (29/50) of integration ratio. Ex-pression level of the positive transgene mice was detected by Western blotting. Maximal expression of human G-CSF was estimated about 540 mg/L of milk. The expression ratio was up to 75% (9/12). The results here have important practical implications for the generation of mammary gland bioreac-tors and other transgene studies. Co-injection of a target gene with an expression vector of a mammal nuclear localization signal by cytoplasm appears to be a useful, efficient and easy strategy for generatingJingpu Zhang Yuge Wang Guangsan Li Yu Shen Shaoxia Zhu Miao Du 2002Chinese Science Bulletin2002,47,3:1
