1Mercury Emission From Coal-fired Power Plants in China显示文摘燃煤是最大的人为汞排放源之一,燃煤电厂的汞排放控制问题也越来越为人们所关注。该文将目前公布的中国电厂的汞排放数据进行筛选汇总,得到18个电厂的汞排放数据,通过对比和分析,总结出了符合我国燃煤电厂特点的一般性汞排放规律。结果表明:与美国煤种相比,我国的燃煤具有低氯、高灰的特性,这不利于汞的排放控制;循环流化床燃烧可能会因燃尽率的不同而较煤粉炉燃烧易获得较高的Hgp;空气污染控制设备的使用能够有效地减少汞排放,选择性催化还原+静电除尘器/布袋除尘器+石灰石-石膏湿法脱硫(SCR+ESP/FF+WFGD)组合的平均脱汞率可达71.48%;SCR的大规模应用可能会将汞大量转移到飞灰和脱硫石膏中,带来二次污染的问题。YIN Libao ZHUO Yuqun XU Qisheng ZHU Zhenwu DU Wen AN Zhongyi 2013中国电机工程学报2013,33,29:29
2Fate of mercury in flue gas desulfurization gypsum determined by Temperature Programmed Decomposition and Sequential Chemical Extraction显示文摘A considerable amount of Hg is retained in flue gas desulfurization(FGD) gypsum from Wet Flue Gas Desulfurization(WFGD) systems. For this reason, it is important to determine the species of Hg in FGD gypsum not only to understand the mechanism of Hg removal by WFGD systems but also to determine the final fate of Hg when FGD gypsum is disposed. In this study, Temperature Programmed Decomposition(TPD) and Sequential Chemical Extraction(SCE) were applied to FGD gypsum to identify the Hg species in it. The FGD gypsum samples were collected from seven coal-fired power plants in China, with Hg concentrations ranging from 0.19 to 3.27 μg/g. A series of pure Hg compounds were used as reference materials in TPD experiments and the results revealed that the decomposition temperatures of different Hg compounds increase in the order of Hg_2Cl_2< HgCl_2< black HgS < Hg_2SO_4< red HgS < HgO < HgSO_4. The Hg compounds existing in FGD gypsums identified by TPD included HgCl_2, Hg_2Cl_2, Hg_2SO_4, black HgS and red HgS, of which mercury sulfides were the primary compounds. The results of SCE indicated that Hg was mainly distributed in the strongly complexed phase. The low Hg content in FGD gypsum increases the ambiguity of assigning extraction fractions to certain Hg species by SCE. The fact that the primary compounds in FGD gypsum are HgS phases leads the leaching of Hg in the natural environment to be quite low, but a considerable amount of Hg may be released during the industrial heating process.Zhenwu Zhu Yuqun Zhuo Yaming Fan Zhipeng Wang 2016Journal of Environmental Sciences2016,28,5:8
3Change of BMD after Weaning or Resumption of Menstruation in Chinese Women with Different FokI VDR-genotypes:A Randomized,Placebo-controlled,Calcium Supplementation Trial显示文摘Objective To investigate the effect of calcium supplementation on bone mineral density (BMD) in Chinese women with different FokI vitamin D receptor (VDR) genotypes (FF,Ff,and ff) after weaning or resumption of menstruation during lactation.Methods A total of 40 subjects with the same FokI VDR genotype were randomly divided into two groups:one received calcium tablet (600 mg once daily as CaCO 3) and the other placebo tablet once daily for 1 year.At baseline,BMD was measured by dual‐energy X‐ray absorptiometry at lumbar spine (L2‐L4) and at left hip whereas serum PICP,serum OC,and urinary CTX,serum 25(OH)VitD 3,and serum estradiol were measured at weaning and 1 year thereafter.Results After the intervention,BMD at lumbar spine and at left hip increased significantly in all these women with a trend among different FokI VDR genotypes such as FF > Ff > ff (P<0.05,<0.01,and <0.001,respectively).BMD at lumbar spine in women with FF VDR genotype increased much more rapidly than in those with ff VDR genotype (P<0.05).Compared with the control group women with the FF genotype regained more BMD after calcium supplementation (P<0.05).Conclusion Daily calcium 600 mg supplementation has beneficial effect on the bone health of women with FF VDR genotype.YU Bo WU HongYing LI Fang GONG Jie ZHOU DunJin ZHANG ZhiFeng YANG XiaoGuang HUANG ZhenWu 2011Biomedical and Environmental Sciences2011,24,3:6
4Characteristics of Upper Mantle Activity in the South China Sea Region and the Indochina Mantle Plume显示文摘According to computed results of the mantle traction field beneath the lithosphere based on satellite-modelled gravity anomalies of different degrees, it has been revealed that the three types of mantle convection on different scales existing in the South China Sea region is the key factor controlling the geodynamics. The mantle convection models on large and middle scales have been proved by natural seismic S-wave tomographic data and interpreted by using the present mantle plume concept In consideration of other relevant geological and geophysical data, the authors put emphasis on discussing the expression form, origin and age of the Indochina mantle plume and its important effect on the conversion of organic matter and hydrocarbon accumulation in Cenozoic basins.WU Nengyou ZENG Weijun LI Zhenwu CHEN Yizhong WEN Xiwen DU Deli LI Guosheng 1999Acta Geologica Sinica(English Edition)1999,73,4:6
5Integrin-interacting protein Kindlin-2 induces mammary tumors in transgenic mice显示文摘Kindlin-2, an integrin-interacting protein, regulates breast cancer progression. However, currently, no animal model to study the role of Kindlin-2 in the carcinogenesis of mammary gland is available. We established a Kindlin-2 transgenic mouse model using a mammary gland-specific promoter, mammary tumor virus(MMTV) long terminal repeat(LTR). Kindlin-2 was overexpressed in the epithelial cells of the transgenic mice. The mammary gland ductal trees were found to grow faster in MMTV-Kindlin-2 transgenic mice than in control mice during puberty. Kindlin-2 promoted mammary gland growth as indicated by more numerous duct branches and larger lumens, and more alveoli were formed in the mammary glands during pregnancy under Kindlin-2 overexpression. Importantly, mammary gland-specific expression of Kindlin-2 induced tumor formation at the age of 55 weeks on average. Additionally, the levels of estrogen receptor and progesterone receptor were decreased, whereas human epidermal growth factor receptor 2 and β-catenin were upregulated in the Kindlin-2-induced mammary tumors. These findings demonstrated that Kindlin-2 induces mammary tumor formation via activation of the Wnt signaling pathway.Bing Li Xiaochun Chi Jiagui Song Yan Tang Juan Du Xiaokun He Xiaoran Sun Zhenwu Bi Yunling Wang Jun Zhan Hongquan Zhang 2019Science China(Life Sciences)2019,62,2:6
6The genome of Medicago polymorpha provides insights into its edibility and nutritional value as a vegetable and forage legume显示文摘Medicago polymorpha is a nutritious and palatable forage and vegetable plant that also fixes nitrogen.Here,we reveal the chromosome-scale genome sequence of M.polymorpha using an integrated approach including Illumina,PacBio and Hi-C technologies.We combined PacBio full-length RNA-seq,metabolomic analysis,structural anatomy analysis and related physiological indexes to elucidate the important agronomic traits of M.polymorpha for forage and vegetable usage.The assembled M.polymorpha genome consisted of 457.53Mb with a long scaffold N50 of 57.72Mb,and 92.92%(441.83Mb)of the assembly was assigned to seven pseudochromosomes.Comparative genomic analysis revealed that expansion and contraction of the photosynthesis and lignin biosynthetic gene families,respectively,led to enhancement of nutritious compounds and reduced lignin biosynthesis in M.polymorpha.In addition,we found that several positively selected nitrogen metabolism-related genes were responsible for crude protein biosynthesis.Notably,the metabolomic results revealed that a large number of flavonoids,vitamins,alkaloids,and terpenoids were enriched in M.polymorpha.These results imply that the decreased lignin content but relatively high nutrient content of M.polymorpha enhance its edibility and nutritional value as a forage and vegetable.Our genomic data provide a genetic basis that will accelerate functional genomic and breeding research on M.polymorpha as well as other Medicago and legume plants.Jiawen Cui Zhaogeng Lu Tianyi Wang Gang Chen Salma Mostafa Hailong Ren Sian Liu Chunxiang Fu Li Wang Yingfang Zhu Jinkai Lu Xiang Chen Zhenwu Wei Biao Jin 2021Horticulture Research2021,8,1:6
7Genetic association and epistatic interaction of the interleukin-10 signaling pathway in pediatric inflammatory bowel disease显示文摘AIM To study the genetic association and epistatic interaction of the interleukin(IL)-10 and IL-10/STAT3 pathways in pediatric inflammatory bowel disease(IBD). METHODS A total of 159 pediatric inflammatory IBD patients(Crohn's disease,n = 136; ulcerative colitis,n = 23) and 129 matched controls were studied for genetic association of selected single nucleotide polymorphisms(SNPs) of the IL-10 gene and the genes IL10 RA,IL10 RB,STAT3,and HO1,from the IL-10/STAT3 signaling pathway. As interactions between SNPs from different loci may significantly affect the associated risk for disease,additive(a) and dominant(d) modeling of SNP interactions was also performed to examine highorder epistasis between combinations of the individual SNPs. RESULTS The results showed that IL-10 rs304496 was associated with pediatric IBD(P = 0.022),but no association was found for two other IL-10 SNPs,rs1800872 and rs2034498,or for SNPs in genes IL10 RA,IL10 RB,STAT3,and HO1. However,analysis of epistatic interaction among these genes showed significant interactions:(1) between two IL-10 SNPs rs1800872 and rs3024496(additive-additive P = 0.00015,Bonferroni P value(Bp) = 0.003);(2) between IL-10 RB rs2834167 and HO1 rs2071746(dominant-additive,P = 0.0018,Bp = 0.039); and(3) among IL-10 rs1800872,IL10 RB rs2834167,and HO1 rs2071746(additivedominant-additive,P = 0.00015,Bp = 0.005),as well as weak interactions among IL-10 rs1800872,IL-10 rs3024496,and IL-10RA(additive-additive-additive,P = 0.003; Bp = 0.099),and among IL10 RA,IL10 RB,and HO1 genes(additive-dominant-additive,P = 0.008,Bp = 0.287).CONCLUSION These results indicate that both the IL-10 gene itself,and through epistatic interaction with genes within the IL-10/STAT3 signaling pathway,contribute to the risk of pediatric IBD.Zhenwu Lin Zhong Wang John P Hegarty Tony R Lin Yunhua Wang Sue Deiling Rongling Wu Neal J Thomas Joanna Floros 2017World Journal of Gastroenterology2017,23,27:5
8A new higher-order shear deformation theory and refined beam element of composite laminates显示文摘A new higher-order shear deformation theory based on global-local superposition technique is developed. The theory satisfies the free surface conditions and the geometric and stress continuity conditions at interfaces. The global displacement components are of the Reddy theory and local components are of the internal first to third-order terms in each layer. A two-node beam element based on this theory is proposed. The solutions are compared with 3D-elasticity solutions. Numerical results show that present beam element has higher computational efficiency and higher accuracy.WanjiChen ZhenWu 2005Acta Mechanica Sinica2005,21,1:3
9Dynamic culture of a thermosensitive collagen hydrogel as an extracellular matrix improves the construction of tissue-engineered peripheral nerve显示文摘Tissue engineering technologies offer new treatment strategies for the repair of peripheral nerve injury, but cell loss between seeding and adhesion to the scaffold remains inevitable. A thermosensitive collagen hydrogel was used as an extracellular matrix in this study and combined with bone marrow mesenchymal stem cells to construct tissue-engineered peripheral nerve composites in vitro. Dynamic culture was performed at an oscillating frequency of 0.5 Hz and 35° swing angle above and below the horizontal plane. The results demonstrated that bone marrow mesenchymal stem cells formed membrane-like structures around the poly-L-lactic acid scaffolds and exhibited regular alignment on the composite surface. Collagen was used to fill in the pores, and seeded cells adhered onto the poly-L-lactic acid fibers. The DNA content of the bone marrow mesenchymal stem cells was higher in the composites constructed with a thermosensitive collagen hydrogel compared with that in collagen I scaffold controls. The cellular DNA content was also higher in the thermosensitive collagen hydrogel composites constructed with the thermosensitive collagen hydrogel in dynamic culture than that in static culture. These results indicate that tissue-engineered composites formed with thermosensitive collagen hydrogel in dynamic culture can maintain larger numbers of seeded cells by avoiding cell loss during the initial adhesion stage. Moreover, seeded cells were distributed throughout the material.Lanfeng Huang Rui Li Wanguo Liu Jin Dai Zhenwu Du Xiaonan Wang Jianchao Ma Jinsong Zhao 2014Neural Regeneration Research2014,9,14:3
10The Africanness of African Literatures and New Patterns in Human Civilization显示文摘The explosion of African literatures in 2021 is not a coincidence,but is dictated by the continent's decolonial,diasporic and hybrid cultural manifestations,its more than a hundred years of struggle for cross-regional integration,its spirit of vigorous and persistent action,and the unique attraction of an Africanness that upholds its selfhood,bridges the gaps,and remembers its history but looks to the future.The diasporic characteristic of attending to,absorbing and squarely facing the tension of heterogeneous cultures means that indigenous African literatures contain a distinctive world consciousness and rational philosophy.They have given rise to diverse civilizations marked by dialogue,inclusiveness and the contemporary spirit of African nations,enabling African literatures to participate effectively in the dialogue of world literature and in new patterns of civilization,displaying as they do a strong vitality,creativity and influence in the positive-sum game with Western culture.This will provide positive encouragement to the mutual learning,integration,harmony,symbiosis andcoexistenceofcivilizations.Zhu Zhenwu Li Dan 邵亚楠(译) 2022Social Sciences in China2022,43,3:2
