| 3 | Heavy Metal Transfer from Soil to Vegetable in Southern Jiangsu Province, China显示文摘Vegetable fields in peri-urban areas receive large amounts of extraneous heavy metals because of rapid urbanization and industrialization in China. The concentrations of Cu, Zn, and Pb in 30 soil samples and 32 vegetable samples, collected from 30 different sites in southern Jiangsu Province of China, were measured and their transfer from soil to vegetable was determined. The results showed that the soil samples had wide ranges of pH (4.25–7.85) and electrical conductivity (EC) (0.24–3.42 dS m-1). Among the soil samples, there were four soil samples containing higher Cu and two soil samples containing higher Zn concentrations than those specified in the Chinese Soil Environmental Quality Standard II. However, no vegetable sample was found to contain a high level of Cu or Zn. In contrast, one vegetable sample contained 0.243 mg Pb kg-1 FW, which was above the Chinese Food Hygiene Standard, whereas the corresponding soil Pb concentration was lower than the Chinese Soil Environmental Quality Standard II. The transfer coefficients of Cu of all vegetable samples exceeded the suggested coefficient range, implying that extraneous Cu had high mobility and bioavailability to vegetables. There was no significant correlation between extractable soil heavy metal concentrations with four kinds of extractants and soil pH, EC, heavy metal concentrations in vegetables and soils, except that soil pH correlated well with the extractable soil Cu, Zn, and Pb concentrations with 1.0 mol L-1 NH4NO3. Moreover, diethylenetriamine pentaacetic acid (DTPA) extraction method was a more effcient method of extracting heavy metals from the soils independent of soil pH and EC than other three methods used. | HAO Xiu-Zhen ZHOU Dong-Mei HUANG De-Qian CANG Long ZHANG Hai-Lin WANG Hui | 2009 | Pedosphere2009，19，3： | 46 |
| 4 | Expression,deleton and mnutation of ρ16 gene in human gastric cancer显示文摘AIM To investigate the relationship between the expression of p16 gene and the gastric carcinogenesis,depth of invasion and lymph node metastases, and to evaluate the deletion and mutation of exon 2 in p16 gene in gastric carcinoma.METHODS The expression of P16 protein was examined by streptavidin-peroxidase conjugated method (S-P); the deletion and mutation of p16 gene were respectively examined by polymerase chain reaction (PCR) and polymerase chain reaction single-strand conformation polymorphism analysis (PCR-SSCP) in gastric carcinoma.RESULTS Expression of P16 protein was detected in 96.25% (77/80) of the normal gastric mucosa, in 92.00% (45/50) of the dysplastic gastric mucosa and in 47.54% (58/122) of the gastric carcinoma. The positive rate of P16 protein expression in gastric carcinoma was significantly lower than that in normal gastric mucosa and dysplastic gastric mucosa (P<0.05). The positive rate of P16 protein expression in mucoid carcinoma 10.00% (1/ 10) was significantly lower than that in poorly differentiated carcinoma 51.22% ( 21/ 41 ),undifferentiated carcinoma 57.69% (15/26) and signet ring cell carcinoma 62.50% (10/ 16) (P<0.05). The positive rate of p16 protein in 30 cases paired primary and lymph node metastatic gastric carcinoma: There was 46.67% (14/30) in primary gastric carcinoma, 16.67% (5/30) in lymph node metastatic gastric carcinoma. The positive rate of lymph node metastatic carcinoma was significantly lower than that of primary carcinoma (P<0.05). There was of p16 gene mutation in exon 2, but 5 cases displayed deletion of p16 gene in exon 2 in the 25 primary gastric carcinomas.CONCLUSIONS The expression loss of P16 protein related to the gastric carcinogenesis, gastric carcinoma histopathological subtypes and lymph metastasis. The mutation of p16 gene in exon 2 may not be involved in gastric carcinogenesis. But the deletion of p16 gene in exon 2 may be involved in gastric carcinogenesis. | Xiu-Sheng He Qi Su Zhu-Chu Chen Xiu-Tao He Zhi-Feng Long Hui Ling Liang-Run Zhang Oncology Institute,Nanhua University,Hengyang 421001,Hunan Province,ChinaOncology Institute,Center South University,Changsha 410078,Hunan Province,China Department of Gastroenterology,First People’s Hospital of Changde City,Changde 415003,Hunan Province,China | 2001 | World Journal of Gastroenterology2001，7，4： | 40 |
| 5 | Geochemical and Pb-Sr-Nd isotopic compositions of Indosinian granitoids from the Bikou block,northwest of the Yangtze plate:Constraints on petrogenesis,nature of deep crust and geodynamics显示文摘This paper reports geochemical and Pb-Sr-Nd isotopic compositions of the Indosinian Yangba (215 Ma),Nanyili (225 Ma) and Mopi granitoids from the Bikou block of the northwestern margin of the Yangtze plate. These granitoids are enriched in Al (Al2O3:14.56%―16.48%) and Sr (352 μg/g―1047 μg/g),and depleted in Y (<16 μg/g) and HREE (e.g. Yb<1.61 μg/g),resulting in high Sr/Y (36.3―150) and (La/Yb)N (7.8―36.3) ratios and strongly fractionationed REE patterns. The Indosinian granotoids show initial Sr isotopic ratios (ISr) from 0.70419 to 70752,εNd(t) values from-3.1 to -8.5,and initial Pb isotopic ratios 206Pb/204Pb=17.891-18.250,207Pb/204Pb=15.494-15.575,and 208Pb/204Pb=37.788-38.335. Their geochemi-cal signatures indicate that the granitoids are adakitic. However,they are distinct from some adakites,generated by partial melting of subducted oceanic slab and/or underplated basaltic lower crust,be-cause they have high K (K2O: 1.49%―3.84%) and evolved Nd isotopic compositions,with older Nd iso-topic model ages (TDM=1.06―1.83 Ga). Geochemical and Sr-Nd isotopic compositions suggest that the magmas of the Insoninian adakitic rocks in the Bikou block were derived from partial melting of thick-ened basaltic lower crust. Combined with regional analyses,a lithospheric delamination model after collision between the North China and South China plates can account for the Indosinian adakitic magma generation. On the other hand,based on the Pb-Sr-Nd isotopic probing to the magma sources of the adakitic rocks,it is suggested that there is an unexposed continent-type basement under the exposed Bikou Group volcanic rocks. This can constrain on the Bikou Group volcanic rocks not to be MORB-or OIB-type. | ZHANG HongFei XIAO Long ZHANG Li YUAN HongLin JIN LanLan | 2007 | Science China Earth Sciences2007，50，7： | 38 |
| 6 | Antimony speciation in the environment:Recent advances in understanding the biogeochemical processes and ecological effects显示文摘Antimony(Sb) is a toxic metalloid, and its pollution has become a global environmental problem as a result of its extensive use and corresponding Sb-mining activities. The toxicity and mobility of Sb strongly depend on its chemical speciation. In this review, we summarize the current knowledge on the biogeochemical processes(including emission, distribution,speciation, redox, metabolism and toxicity) that trigger the mobilization and transformation of Sb from pollution sources to the surrounding environment. Natural phenomena such as weathering, biological activity and volcanic activity, together with anthropogenic inputs, are responsible for the emission of Sb into the environment. Sb emitted in the environment can adsorb and undergo redox reactions on organic or inorganic environmental media, thus changing its existing form and exerting toxic effects on the ecosystem. This review is based on a careful and systematic collection of the latest papers during 2010–2017 and our research results, and it illustrates the fate and ecological effects of Sb in the environment. | Mengchang He Ningning Wang Xiaojing Long Chengjun Zhang Congli Ma Qianyun Zhong Aihua Wang Ying Wang Aneesa Pervaiz Jun Shan | 2019 | Journal of Environmental Sciences2019，31，1： | 40 |

| 12 | SQUAMOSA Promoter-Binding Protein-Like Transcription Factors:Star Players for Plant Growth and Development显示文摘SQUAMOSA Promoter-Binding Protein-Like (SPL) genes encode plantspecific transcription factors that play important roles in plant phase transition,flower and fruit development,plant architecture,gibberellins signaling,sporogenesis,and response to copper and fungal toxins.In Arabidopsis,many SPL genes are post-transcriptionally regulated by the microRNA (miRNA) miR156,among which AtSPL9 in turn positively regulates the expression of the second miRNA miR172.This miR156AtSPL9-miR172 regulatory pathway plays critical roles during juvenile to adult leaf development and the miR156-SPLs feedback interaction persists all through the plant development,which may be conserved in other plants.In the present paper,we provide a concise review on the most recent progress in the regulatory mechanisms associated with plant SPL transcription factors,especially in relation to miRNAs.The potential application of these discoveries in agriculture is briefly discussed. | Xiaobo Chen Zenglin Zhang Danmei Liu Kai Zhang Aili Li Long Mao | 2010 | Journal of Integrative Plant Biology2010，52，11： | 31 |
| 13 | A Survey: Several Technologies of Non-Orthogonal Transmission for 5G显示文摘One key advantage of 4G OFDM system is the relatively simple receiver implementation due to the orthogonal resource allocation.However,from sum-capacity and spectral efficiency points of view,orthogonal systems are never the achieving schemes.With the rapid development of mobile communication systems,a novel concept of non-orthogonal transmission for 5G mobile communications has attracted researches all around the world.In this trend,many new multiple access schemes and waveform modulation technologies were proposed.In this paper,some promising ones of them were discussed which include Non-orthogonal Multiple Access(NOMA),Sparse Code Multiple Access(SCMA),Multi-user Shared Access(MUSA),Pattern Division Multiple Access(PDMA)and some main new waveforms including Filter-bank based Multicarrier(FBMC),Universal Filtered Multi-Carrier(UFMC),Generalized Frequency Division Multiplexing(GFDM).By analyzing and comparing features of these technologies,a research direction of guiding on future 5G multiple access and waveform are given. | TAO Yunzheng LIU Long LIU Shang ZHANG Zhi | 2015 | China Communications2015，12，10： | 31 |
| 14 | Rural vitalization in China:A perspective of land consolidation显示文摘The core objective of rural vitalization is to systemically establish a coupling pattern of various rural development elements including population,land and industry.As one of the prerequisites,land resources is required to be optimally allocated via land consolidation.Con seque ntly,la nd con solidati on con tributes greatly to population agglomeration,industrial developme nt and resources support under the con text of combati ng rural decline.Based on the key eleme nts affecting rural development,this paper elaborates the con no tation of rural vitalization and land consolidation in the new era as well as their relationships.Furthermore,the paper analyzes the alternative paths for achieving rural vitalization via land consolidation,and discusses the future directions of land consolidation and rural vitalization.The conclusions are drawn as follows:(1)To cope with the loss and decline of the intrinsic elements in rural areas,rural vitalization is a development strategy aimed at realizing economic,political,cultural and ecological rejuvenation in rural area by reshaping socio?economic morphology and spatial pattern in rural territory.(2)From the perspective of rural vitalization,land consolidation is endowed with new connotation,which should not only target at activating the key elements of rural development,but also place emphasis on coordimating material space and spirit core as well as integrating the restructuring of the physical space and the rural gov?ernance system.(3)Land consolidation should be compatible with regional natural conditions and the current stage of socio-economic development.According to the principle of regional planning and classification strategy,the appropriate models and paths should be adopted to promote the benign interactions of population,land and industry based on engineering techniques and ecological means.(4)Under the background of national strategy of rural vitaliza?tion,it is n ecessary to reshape the value orientati on of la nd con solidation based on a scie tific understanding of urban-rural relations and rural territorial functions,coordinate land consolidation planning and rural vitalization planning under the unified spatial planning system,and explore the new model combining land consolidation and multifunctional agriculture. | LONG Hualou ZHANG Yingnan TU Shuangshuang | 2019 | Journal of Geographical Sciences2019，29，4： | 33 |
| 15 | Dual gRNAs guided CRISPR/Cas9 system inhibits hepatitis B virus replication显示文摘AIM: To screen and investigate the effective g RNAs against hepatitis B virus(HBV) of genotypes A-D.METHODS: A total of 15 g RNAs against HBV of genotypes A-D were designed. Eleven combinations of two above g RNAs(dual-g RNAs) covering the regulatory region of HBV were chosen. The efficiency of each g RNA and 11 dual-g RNAs on the suppression of HBV(genotypes A-D) replication was examined by the measurement of HBV surface antigen(HBs Ag) or e antigen(HBe Ag) in the culture supernatant. The destruction of HBV-expressing vector was examined in Hu H7 cells co-transfected with dual-g RNAs and HBVexpressing vector using polymerase chain reaction(PCR) and sequencing method, and the destruction of ccc DNAwas examined in Hep AD38 cells using KCl precipitation, plasmid-safe ATP-dependent DNase(PSAD) digestion, rolling circle amplification and quantitative PCR combined method. The cytotoxicity of these g RNAs was assessed by a mitochondrial tetrazolium assay.RESULTS: All of g RNAs could significantly reduce HBs Ag or HBe Ag production in the culture supernatant, which was dependent on the region in which g RNA against. All of dual g RNAs could efficiently suppress HBs Ag and/or HBe Ag production for HBV of genotypes A-D, and the efficacy of dual g RNAs in suppressing HBs Ag and/or HBe Ag production was significantly increased when compared to the single g RNA used alone. Furthermore, by PCR direct sequencing we confirmed that these dual g RNAs could specifically destroy HBV expressing template by removing the fragment between the cleavage sites of the two used g RNAs. Most importantly, g RNA-5 and g RNA-12 combination not only could efficiently suppressing HBs Ag and/or HBe Ag production, but also destroy the ccc DNA reservoirs in Hep AD38 cells.CONCLUSION: These results suggested that CRISPR/Cas9 system could efficiently destroy HBV expressing templates(genotypes A-D) without apparent cytotoxicity. It may be a potential approach for eradication of persistent HBV ccc DNA in chronic HBV infection patients. | Jie Wang Zhong-Wei Xu Shuang Liu Rui-Yang Zhang Shan-Long Ding Xiao-Meng Xie Lu Long Xiang-Mei Chen Hui Zhuang Feng-Min Lu | 2015 | World Journal of Gastroenterology2015，21，32： | 29 |

| 17 | Chemical composition and in vitro fermentation characteristics of high sugar forage sorghum as an alternative to forage maize for silage making in Tarim Basin, China显示文摘The chemical composition, mineral profile and in vitro fermentation characteristics of maize(MZ), high sugar forage sorghum(HS) and forage sorghum(FS), and silages made from each forage type were measured. The MZ and MZ silage(MZS) had higher crude protein, starch and ether extract contents than both sorghum forages and sorghum silages. HS had higher ash and water-soluble carbohydrate concentrations than FS and MZ. MZ, MZS, HS and HS silage(HSS) had lower neutral detergent fibre, acid detergent fibre and acid detergent lignin than FS and FS silage(FSS). FSS had higher dry matter(DM) and p H than MZS and HSS. HSS contained higher concentrations of P and K than FSS and MZS. MZS and HSS had higher in vitro dry matter and organic matter digestibility, CH4 production, total volatile fatty acids, acetate and propionate than FSS. p H was higher for FSS than for HSS, and ammonia was lower for HSS than for MZS and FSS. HSS had higher gas production than MZS and FSS after 2, 4, 6 and 8 h incubation. MZS had higher gas production than HSS and FSS after 26 and 28 h of incubation. The results indicate that HS may substitute for MZ to make good quality silage. However, animal studies are needed to assess the acceptability and feeding values of HSS vs. MZS for ruminant production. | ZHANG Su-jiang Abdul Shakoor Chaudhry Diky Ramdani Amerjan Osman GUO Xue-feng Grant Raymond Edwards Long Cheng | 2016 | Journal of Integrative Agriculture2016，15，1： | 28 |
