5Impact of land use conversion on soil organic carbon stocks in an agro-pastoral ecotone of Inner Mongolia显示文摘Soil organic carbon(SOC) stocks in terrestrial ecosystems vary considerably with land use types. Grassland, forest, and cropland coexist in the agro-pastoral ecotone of Inner Mongolia, China. Using SOC data compiled from literature and field investigations, this study compared SOC stocks and their vertical distributions among three types of ecosystems. The results indicate that grassland had the largest SOC stock, which was 1.5-and 1.8-folds more than stocks in forest and cropland, respectively. Relative to the stock in 0–100 cm depth, grassland held more than 40% of its SOC stock in the upper 20 cm soil layer; forest and cropland both held over 30% of their respective SOC stocks in the upper 20 cm soil layer. SOC stocks in grazed grasslands were remarkably promoted after ≥20 years of grazing exclusion. Conservational cultivation substantially increased the SOC stocks in cropland, especially in the 0–40 cm depth. Stand ages, tree species, and forest types did not have obvious impacts on forest SOC stocks in the study area likely due to the younger stand ages. Our study implies that soil carbon loss should be taken into account during the implementation of ecological projects, such as reclamation and afforestation, in the arid and semi-arid regions of China.ZHAO Wei HU Zhongmin LI Shenggong GUO Qun YANG Hao ZHANG Tonghui 2017Journal of Geographical Sciences2017,27,8:8
6Synthesis and applications of mesoporous Cu-Zn-Al_2O_3 catalyst for dehydrogenation of 2-butanol显示文摘A series of mesoporous Cu-Zn-Al2O3 materials have been synthesized at ambient temperature and their structure was characterized by XRD, N2 physical adsorption and TPR techniques. Their catalytic applications for the dehydrogenation of 2-butanol to methyl ethyl ketone (MEK) were evaluated in a fixed-bed flow reactor at atmospheric pressure. It is demonstrated from the XRD patterns that both the as-synthesized samples and calcined samples have the typical XRD patterns of meso-structured materials and the results of N2O chemical adsorption showed that Cu was embedded in the framework of the mesoporous materials and homogeneously dispersed in the mesoporous Cu-Zn-Al2O3 materials. The catalytic activity of 2-butanol dehydrogenation was varied in the order of CZA(10)Deren Fang Wanzhong Ren Zhongmin Liu Xiufeng Xu Lei Xu Hongying Lǔ Weiping Liao Huimin Zhang 2009Journal of Natural Gas Chemistry2009,18,2:7
7Noise-sidebands-free and ultra-low-RIN 1.5 μm single-frequency fiber laser towards coherent optical detection显示文摘A noise-sidebands-free and ultra-low relative intensity noise(RIN) 1.5 μm single-frequency fiber laser is demonstrated for the first time to our best knowledge. Utilizing a self-injection locking framework and a booster optical amplifier, the noise sidebands with relative amplitudes as high as 20 dB are completely suppressed.The RIN is remarkably reduced by more than 64 dB at the relaxation oscillation peak to retain below-150 dB∕Hz in a frequency range from 75 kHz to 50 MHz, while the quantum noise limit is -152.9 d B∕Hz.Furthermore, a laser linewidth narrower than 600 Hz, a polarization-extinction ratio of more than 23 dB, and an optical signal-to-noise ratio of more than 73 dB are acquired simultaneously. This noise-sidebands-free and ultralow-RIN single-frequency fiber laser is highly competitive in advanced coherent light detection fields including coherent Doppler wind lidar, high-speed coherent optical communication, and precise absolute distance coherent measurement.QILAI ZHAO ZHITAO ZHANG BO WU TIANYI TAN CHANGSHENG YANG JIULIN GAN HUIHUI CHENG ZHOUMING FENG MINGYING PENG ZHONGMIN YANG SHANHUI XU 2018Photonics Research2018,6,4:7
8Multi-functional bismuth-doped bioglasses: combining bioactivity and photothermal response for bone tumor treatment and tissue repair显示文摘Treatment of large bone defects derived from bone tumor surgery is typically performed in multiple separate operations,such as hyperthermia to extinguish residual malignant cells or implanting bioactive materials to initiate apatite remineralization for tissue repair;it is very challenging to combine these functions into a material.Herein,we report the first photothermal(PT)effect in bismuth(Bi)-doped glasses.On the basis of this discovery,we have developed a new type of Bi-doped bioactive glass that integrates both functions,thus reducing the number of treatment cycles.We demonstrate that Bi-doped bioglasses(BGs)provide high PT efficiency,potentially facilitating photoinduced hyperthermia and bioactivity to allow bone tissue remineralization.The PT effect of Bi-doped BGs can be effectively controlled by managing radiative and non-radiative processes of the active Bi species by quenching photoluminescence(PL)or depolymerizing glass networks.In vitro studies demonstrate that such glasses are biocompatible to tumor and normal cells and that they can promote osteogenic cell proliferation,differentiation,and mineralization.Upon illumination with near-infrared(NIR)light,the bioglass(BG)can efficiently kill bone tumor cells,as demonstrated via in vitro and in vivo experiments.This indicates excellent potential for the integration of multiple functions within the new materials,which will aid in the development and application of novel biomaterials.Liping Wang Nicholas J.Long Lihua Li Yao Lu Mei Li Jiangkun Cao Yu Zhang Qinyuan Zhang Shanhui Xu Zhongmin Yang Chuanbin Mao Mingying Peng 2018Light(Science & Applications)2018,7,1:6
9Development of Mathematical Model on Preparation of Functionally Graded Material by Co-sedimentation显示文摘From the process of sedimentation the mathematical relationships among deposition volume and powder properties as well as sedimentation parameters were deduced.

10Types, Metallogenic Environments and Characteristics of Temporal and Spatial Distribution of Copper Deposits in China显示文摘Based upon a comprehensive study of 123 copper deposits in China. this paper reaches the following conclusions: 1. The crust in China was solidified pretty late; with the accretion of the plate, the copper mineralization moved towards its margin in space and became successively younger in age. 2. The major copper ore types ever found in the world have mostly been discovered in China, in which the porphyry type seems to be the most important and the massive sulfide type in the transitional bed between marine clastic and carbonate rocks is clearly defined. 3. Carbonate strata are widespread in China and their deposition lasted for a long geological period, so the proportion of copper deposits occurring in them is large as compared with other parts of the world. 4. Seven metallogenic epochs can be recognized, in which the Mesozoic one plays the leading role and the middle(late) Palaeozoic and Cenozoic ones are next in importance. Mineralization was comparatively simple in the early geological period. and became diversified later on. In the early epochs copper deposits related to basaltic magmatism and metamorphosed marine sediments predominated, whereas in the later epochs those related to granitic magmatism and continental sedimentation were dominant. 5. There exist in China thirteen metallogenic provinces, of which the Lower Yangtze downwarping belt, Sanjiang fold system, Jiangnan axis and Xikang-Yunnan axis are of greater significance. 6. The crustal mobility in China was rather pronounced, the polycyclic evolution of the crust has resulted in such obvious phenomena as the inheritance of mineralization, the coexistence of various types and the superposition of different genetic types.Wang Zhitian and Qin Kezhang Beijing Institute of Geology for Mineral Resources, CNNC, Beijing Zhang Zhongmin 1989Acta Geologica Sinica(English Edition)1989,63,1:5

14A Streptococcus suis serotype 2 caused streptococcal toxic shock syndrome(STSS) in a patient显示文摘Streptococcus suis(S.suis)is a Gram-positive,facultatively anaerobic coccus that has been implicated as the cause of a wide range of clinical disease syndromes in swine and other domestic animals.S.suis has also been implicated in disease in humans,especially among abattoir workers,swine and pork handlers.Here we report a case of streptococcal toxic shock syndrome(STSS)caused by S.suis in a 59-year-old man.Despite of intensive treatment,the patient died of shock with multiple organ failure 14 h after admission.One bacterial isolate obtained from blood culture was identified to the species level by biochemical tests and serological tests as S.suis serotype 2.Identification was confirmed by PCR amplification of genes encoding 16sRNA of S.suis and the capsule of S.suis serotype 2(cps 2J).Genes encoding virulence factors were also detected.An investigation to identify the source of S.suis revealed that several days before admission the affected man had been handling sick pigs or their meat.Transmission may occur through breaks in the skin of feet with tinea due to that no measures for personal protection was taken.This case should highten awareness of the potential for occupational exposure and human infection with S.suis.Yefei Zhu Zhongmin Tan Lingyang Zhu Hongxing Pan Xuejun Zhang Lei Xu Huimin Qian Ling Gu Xun Ye Chen Dong Changjun Bao Rongqiang Zhu Fengcai Zhu Hua Wang 2008Journal of Nanjing Medical University2008,22,5:3
15WEAR AND LIFE OF PCBN TOOLS WHEN DRY-CUTTING BEARING STEEL GCr15显示文摘The wear forms and reasons of PCBN tools when dry-cutting bearing steel GCr15 are studied systematically. The effect law of the workpiece hardness on PCBN tools is gained and tool wearing with the quickest speed at the workpiece critical hardness is proved. The life equation at two kinds of workpiece hardness demonstrates that the effect of the cutting speed on the PCBN tool life is less than that of carbide tools and ceramic tools.Liu Xianli Zhang Zhongmin Li ZhenjiaDepartment of Mechanical Engingeering, Harbin University of Science and Technology,Harbin 150080, ChinaLiu Linjiang Yuan ZhejunJilin University Harbin Institute of Technology 2002Chinese Journal of Mechanical Engineering2002,15,3:3
16A systematic review and meta-analysis of the safety and efficacy of uterine artery embolization vs. surgery for symptomatic uterine fibroids显示文摘Purpose: The aim of this study was to systematically review the safety and efficacy of uterine artery embolization(UAE) versus surgery for symptomatic uterine fibroids. Materials and Methods: An electronic search of the Cochrane Library, PubMed, Embase and Web of Science databases was conducted from their inception to May 2017 for randomized controlled trials(RCTs) that assessed UAE versus surgery for the treatment of symptomatic uterine fibroids. The references of the included studies were also retrieved. Two reviewers independently screened the studies based on the inclusion and exclusion criteria, extracted the data, and assessed the methodological quality. The meta-analysis was conducted using RevMan 5.3 software. Results: A total of seven RCTs involving 859 patients were included. The results of the meta-analysis showed a shorter hospital stay and recovery time for UAE as compared to surgery. Surgery was not reported to be better for improving health-related quality of life in any of the included studies. There were no significant differences in patient satisfaction(1-2 and 5 years), and intra-procedural complications or major complications(1 year). However, the rates of minor complications(1 year) and further interventions(2 and 5 years) were significantly higher in patients who underwent UAE rather than surgery. The rates of pregnancy and live births were significantly lower among patients who underwent UAE than surgery. Conclusion: UAE is safe and effective, and has the advantages of shorter hospital stay and recovery time as compared to surgery. However, UAE has the risk of re-intervention, and lower pregnancy and live birth rates.Shiwei Tang Mingxin Kong XinjianZhao Jun Chen Chen Wang Haibin Zhang Zhongmin Wang 2018Journal of Interventional Medicine2018,1,2:3
17Conversion of syngas to higher alcohols over Cu-Fe-Zr catalysts induced by ethanol显示文摘Ethanol induced method was applied to prepare Cu-Fe-Zr catalysts for conversion of syngas to higher alcohols.The catalytic performance of the catalysts induced by ethanol was superior to that of the catalyst prepared by the conventional precipitation method.Among various procedures for ethanol induced method,it was found that incorporation of ethanol in the precipitation process was the better.After incorporation of ethanol,the crystal size of CuO decreased and the reduction of copper species became easier.The better activity of Cu-Fe-Zr catalysts prepared by ethanol induced procedures was probably caused by the higher dispersion of Cu species.Hongtao Zhang Xiaomei Yang Lipeng Zhou Yunlai Su Zhongmin Liu 2009Journal of Natural Gas Chemistry2009,18,3:3
18A specific aggregation-induced emission-conjugated polymer enables visual monitoring of osteogenic differentiation显示文摘Osteogenic differentiation is the basis of bone growth and repair related to many diseases,in which evaluating the degree and ability of osteogenic transformation is quite important and highly desirable.However,fixing or stopping the growth of cells is required for conventional methods to monitor osteogenic differentiation,which cannot realize the full investigation of the dynamic process.Herein,a new anion conjugated polymer featuring aggregation-induced emission(AIE)characteristics is developed with excellent solubility for in-situ monitoring the process of osteogenic differentiation.This novel polymer can bind with osteogenic differentiated cells,and the intracellular fluorescence increases gradually with the enhancement of osteogenic differentiation.Moreover,it possesses good biosafety with negligible effect on cell activity and osteogenic differentiation,which cannot be realized by the typical method of Alizarin Red S staining.Further study shows that the polymer crosses the cell membrane through endocytosis and enriches in lysosomes,whereas no obvious fluorescence is detected with other cells,including non-differentiated osteoblast cells,under the same conditions,demonstrating the high selectivity.This is the first fluorescent probe with excellent specificity to realize real-time observation of the process of osteogenic differentiation.Therefore,PTB-EDTA shows great promise in the study of osteogenic differentiation and related applications.Zhenyu Zheng Taotao Zhou Rong Hu Minjun Huang Xiang Ao Jun Chu Tao Jiang Anjun Qin Zhongmin Zhang 2020Bioactive Materials2020,5,4:3
19A core-shell structured COYID-19 mRNA vaccine with favorable biodistribution pattern and promising immunity显示文摘Although inoculation of COVID-19 vaccines has rolled out globally,there is still a critical need for safe and effective vaccines to ensure fair and equitable supply for all countries.Here,we report on the development of a highly efficacious mRNA vaccine,SW0123 that is composed of sequence-modified mRNA encoding the full-length SARS-CoV-2 Spike protein packaged in core-shell structured lipopolyplex(LPP)nanoparticles.SWOT 23 is easy to produce using a large-scale microfluidics-based apparatus.The unique core-shell structured nanoparticle facilitates vaccine uptake and demonstrates a high colloidal stability,and a desirable biodistribution pattern with low liver targeting effect upon intramuscular administration.Extensive evaluations in mice and nonhuman primates revealed strong immunogenicity of SW0123,represented by induction of Th1-polarized T cell responses and high levels of antibodies that were capable of neutralizing not only the wild-type SARS-CoV-2,but also a panel of variants including D614G and N501Y variants.In addition,SW0123 conferred effective protection in both mice and non-human primates upon SARS-CoV-2 challenge.Taken together,SW0123 is a promising vaccine candidate that holds prospects for further evaluation in humans.Ren Yang Yao Deng Baoying Huang Lei Huang Ang Lin Yuhua Li Wenling Wang Jingjing Liu Shuaiyao Lu Zhenzhen Zhan Yufei Wang Ruhan A Wen Wang Peihua Niu Li Zhao Shiqiang Li Xiaopin Ma Luyao Zhang Yujian Zhang Weiguo Yao Xingjie Liang Jincun Zhao Zhongmin Liu Xiaozhong Peng Hangwen Li Wenjie Tan 2021Signal Transduction and Targeted Therapy2021,6,6:3
20BSA-seq-based identification of a major additive plant height QTL with an effect equivalent to that of Semi-dwarf 1 in a large rice F_(2) population显示文摘Bulked-segregant analysis is a time-and cost-saving strategy for identifying major quantitative trait loci(QTL) in a mapping population. Bulked-segregant analysis combined with whole-genome sequencing(BSA-seq) was performed to rapidly identify QTL for heading date, plant height, and panicle length in a large F_(2) population derived from two landraces: Chuan 7(C7) and Haoboka(HBK). Twenty plants with extremely low or high phenotypic values for the target traits were selected from an F_(2) population of 940 plants to construct low-and high-value bulks. Three pairs of bulks for the three traits were constructed, resulting in six DNA pools. BSA-seq revealed nine QTL: four for heading date, three for plant height, and two for panicle length. These QTL were validated in a random F_(2) population or BC_(4)F_(2) populations. The major novel plant height QTL, qPH8, acting additively with an effect equivalent to that of semi-dwarf 1(sd1), is potentially valuable for hybrid rice breeding. qPH8 controls mainly the elongation of basal internodes. The C7 allele of qPH8 reduces plant height and increases lodging resistance without yield penalty, suggesting a potential role for qPH8 in improving rice plant architecture.Bo Zhang Feixiang Qi Gang Hu Yikai Yang Li Zhang Jianghu Meng Zhongmin Han Xiangchun Zhou Haiyang Liu Mohammed Ayaad Yongzhong Xing 2021The Crop Journal2021,9,6:3
