| 3 | 飞秒激光参数对石英玻璃微孔加工的影响显示文摘微孔加工是微器件加工中的重要环节,飞秒激光的强烈非线性吸收和'冷加工'特性使其在玻璃微纳加工方面有独特的优势和应用前景。选用石英玻璃作为试验材料,研究飞秒激光参数对微孔深径比及形貌的影响。结果表明,飞秒激光脉冲能量、打孔速度对微孔深径比存在较大影响。随着激光能量和打孔速度的增加,微孔深径比均呈现减小趋势。通过选择适当参数,可以获得深径比大于25∶1且孔形较好、无明显裂纹的长直微孔。为了获得更好的聚焦效果,采用倍频晶体BBO获得了400 nm波长的飞秒激光。用相同聚焦透镜时400 nm飞秒激光加工的微孔比800 nm更小。此外,也对飞秒激光微孔加工中常见的缺陷进行了分析。 | 邢松龄 刘磊 邹贵生 张学谦 白海林 Y N Zhou | 2015 | 中国激光2015，42，4： | 31 |

| 5 | Polymorphisms of MTHFD,plasma homocysteine levels, and risk of gastric cancer in ahigh-risk Chinese population显示文摘Purpose:Accumulative evidence suggests that folate has a protective effect on gastric cancer. The methylenetetrahyd-rofolate dlehydrogenase(MTHFD) plays an important role in folate and homocysteine metabolisms, and polymorphisms of MTHFD may result in disturbance of the folate-mediated homocysteine pathway. The aim of this study is to test the hypothesis that genetic variants of MTHFD and plasma homocysteine levels are associated with risk of gastric cancer and modulated by genotypes of methylenetetrahydrofolate reductase(MTHFR). Experimental Design: We genotyped G1958A and T401C in MTHFD and C677T in MTHFR and detected total plasma homocysteine(tHcy) levels in a case-control study of 589 gastric cancer cases and 635 cancer-free controls in a high-risk Chinese population. Results:The variant genotypes of MTHFD 1958AA and 401CC were associated with a significantly increased risk of gastric canceradjusted odds ratio(OR), 2.05; 95% confidence interval(95% CI),1.34-3.13 for 1958AA; adjusted OR,1.43; 95% CI,1.14-1.80 for 401CC compared with 1958GG/GA and 401TT/TC genotypes, respectively. Both of the effects were more evident in the subjects carrying MTHFR 677CT/TT genotypes. The average tHcy level was significantly higher in gastric cancer cases than in controls(P < 0.01), and the upper quartile of tHcy (> 13.6 mu mol/L) was associated with an 82% significantly increased risk of gastric cancer, compared with the lowest quartile of tHcy(<= 8.0 pmol/L;adjusted OR,1.82; 95% CI,1.20-2.75). Conclusions:The strong associations between MTHFD variants and the plasma tHcy levels and gastric cancer risk suggest, for the first time, a possible gene-environment interaction between genetic variants of folate-metabolizing genes and high tHcy levels in gastric carcinogenesis. | Wang, L.

| 6 | Theoretical prediction,synthesis,and crystal structure determination of new MAX phase compound V2SnC显示文摘Guided by the theoretical prediction,a new MAX phase V2SnC was synthesized experimentally for the first time by reaction of V,Sn,and C mixtures at 1000°C.The chemical composition and crystal structure of this new compound were identified by the cross-check combination of first-principles calculations,X-ray diffraction(XRD),energy dispersive X-ray spectroscopy(EDS),and high resolution scanning transmission electron microscopy(HR-STEM).The stacking sequence of V2C and Sn layers results in a crystal structure of space group P63/mmc.The a-and c-lattice parameters,which were determined by the Rietveld analysis of powder XRD pattern,are 0.2981(0)nm and 1.3470(6)nm,respectively.The atomic positions are V at 4f(1/3,2/3,0.0776(5)),Sn at 2d(2/3,1/3,1/4),and C at 2a(0,0,0).A new set of XRD data of V2SnC was also obtained.Theoretical calculations suggest that this new compound is stable with negative formation energy and formation enthalpy,satisfied Born-Huang criteria of mechanical stability,and positive phonon branches over the Brillouin zone.It also has low shear deformation resistance c44(second-order elastic constant,cij)and shear modulus(G),positive Cauchy pressure,and low Pugh’s ratio(G/B=0.500<0.571),which is regarded as a quasi-ductile MAX phase.The mechanism underpinning the quasi-ductility is associated with the presence of a metallic bond. | Qiang Xu Yanchun Zhou Haiming Zhang Anna Jiang Quanzheng Tao Jun Lu Johanna Rosén Yunhui Niu Salvatore Grasso Chunfeng Hu | 2020 | Journal of Advanced Ceramics2020，9，4： | 8 |
| 7 | Effects of reclaimed water irrigation and nitrogen fertilization on the chemical properties and microbial community of soil显示文摘The ecological effect of reclaimed water irrigation and fertilizer application on the soil environment is receiving more attention.Soil microbial activity and nitrogen(N)levels are important indicators of the effect of reclaimed water irrigation on environment.This study evaluated soil physicochemical properties and microbial community structure in soils irrigated with reclaimed water and receiving varied amounts of N fertilizer.The results indicated that the reclaimed water irrigation increased soil electrical conductivity(EC)and soil water content(SWC).The N treatment has highly significant effect on the ACE,Chao,Shannon(H)and Coverage indices.Based on a 16S ribosomal RNA(16S rRNA)sequence analysis,the Proteobacteria,Gemmatimonadetes and Bacteroidetes were more abundant in soil irrigated with reclaimed water than in soil irrigated with clean water.Stronger clustering of microbial communities using either clean or reclaimed water for irrigation indicated that the type of irrigation water may have a greater influence on the structure of soil microbial community than N fertilizer treatment.Based on a canonical correspondence analysis(CCA)between the species of soil microbes and the chemical properties of the soil,which indicated that nitrate N(NO_3~–-N)and total phosphorus(TP)had significant impact on abundance of Verrucomicrobia and Gemmatimonadetes,meanwhile the p H and organic matter(OM)had impact on abundance of Firmicutes and Actinobacteria significantly.It was beneficial to the improvement of soil bacterial activity and fertility under 120 mg kg^(–1) N with reclaimed water irrigation. | GUO Wei Mathias N Andersen QI Xue-bin LI Ping LI Zhong-yang FAN Xiang-yang ZHOU Yuan | 2017 | Journal of Integrative Agriculture2017，16，3： | 7 |
| 8 | Quantitative diffusion-weighted magnetic resonance enterography in ileal Crohn’s disease: A systematic analysis of intra and interobserver reproducibility显示文摘BACKGROUND Magnetic resonance enterography(MRE) is increasingly attractive as a noninvasive and radiation-free tool for assessing Crohn’s disease(CD). Diffusionweighted imaging(DWI) is recommended as an optional MRE sequence for CD by the European Society of Gastrointestinal and Abdominal Radiology, and has shown a superb potential as a quantitative modality for bowel inflammation evaluation. However, the measurement reproducibility of quantitative DWI analysis in MRE has not been ascertained so far. To facilitate the application of quantitative diffusion-weighted MRE in the clinical routine, systematic investigations of the intra and interobserver reproducibility of DWI quantitative parameters should be performed.AIM To evaluate the intra and interobserver reproducibility of quantitative analysis for diffusion-weighted MRE(DW-MRE) in ileal CD.METHODS Forty-four subjects(21 with CD and 23 control subjects) who underwent ileocolonoscopy and DW-MRE(b = 800 s/mm2) within one week were included.Two radiologists independently measured apparent diffusion coefficients(ADC)of the terminal ileum and signal intensity ratio(SR) of the terminal ileum to ipsilateral psoas muscle on DWI images(b = 800 s/mm2). Between-and withinreader agreements were assessed using intraclass correlation coefficients(ICC),coefficients of variation(CoV), and 95% limits of agreement of Bland-Altman plots(BA-LA LoA). Diagnostic performances of ADC and SR for identifying inflamed terminal ileum from the normal were evaluated by receiver operating characteristic(ROC) curve analysis.RESULTS There were no significant differences in ADC or SR values between the two sessions or between the two radiologists either in the CD or control group(paired t-test, P > 0.05). The intra and interobserver reproducibility of ADC(ICC: 0.952-0.984;CoV: 3.73-6.28%;BA-LA LoA: ±11.27% to ±15.88%) and SR(ICC: 0.969-0.989;CoV: 3.51%-4.64%;BA-LA LoA: ±10.62% to ±15.45%) was excellent for CD.Agreement of ADC measurements was slightly less in control subjects(ICC:0.641-0.736;CoV: 10.47%-11.43%;BA-LA LoA: ± 26.59% to ± 30.83%). SR of normal terminal ileum demonstrated high intra and interobserver reproducibility(ICC: 0.944-0.974;CoV: 3.73%-6.28%;BA-LA LoA: ± 18.58% to ± 24.43%). ADC and SR of two readers had outstanding diagnostic efficiencies(area under the ROC curve: 0.923-0.988).CONCLUSION Quantitative parameters derived from DW-MRE have good to excellent intra and interobserver agreements with high diagnostic accuracy, and can serve as robust and efficient quantitative biomarkers for CD evaluation. | Hao Yu Ya-Qi Shen Fang-Qin Tan Zi-Ling Zhou Zhen Li Dao-Yu Hu John N Morelli | 2019 | World Journal of Gastroenterology2019，25，27： | 7 |
| 9 | Development of Soybean EST-SSR Markers and Their Use to Assess Genetic Diversity in the Subgenus Soja显示文摘Developing expressed sequence tag-derived SSR(EST-SSR)markers is imperative in genetic research.In this paper,we reported 37 EST-SSR markers which were developed from 286 unigenes obtained from soybean cDNA library.Among the 286 markers designed for the 4 accessions of Glycine max and 6 of its wild progenitor(G.soja)within the subgenus Soja,209 markers amplified DNA fragments,taking 73.1% and 37 markers appeared to be polymorphic,which was 12.9% of the total.The 37 loci detected a total of 142 alleles,while the PIC values varied from 0.194 to 0.794.Both the number of alleles per locus and PIC value were significantly related to the SSR motif.Six EST-SSR loci may be fixed for different alleles between G.max and G.soja since they were particularly polymorphic among the 6 G.soja accessions.A neighbor-joining tree placed the G.max accessions together as a group within the G.soja,though the average genetic distance among G.soja accessions was much higher.These new EST-SSRs markers will be useful for genetic diversity analysis,genetic mapping construction and gene discovery in Soja subgenus. | LIU Yu-lin LI Ying-hui ZHOU Guo-an Uzokwe N CHANG Ru-zhen CHEN Shou-yi QIU Li-juan | 2010 | Agricultural Sciences in China2010，9，10： | 6 |
