2Climate and litter C/N ratio constrain soil organic carbon accumulation显示文摘Soil organic carbon(SOC) plays critical roles in stabilizing atmospheric CO2 concentration, but the mechanistic controls on the amount and distribution of SOC on global scales are not well understood. In turn, this has hampered the ability to model global C budgets and to find measures to mitigate climate change. Here, based on the data from a large field survey campaign with 2600 plots across China’s forest ecosystems and a global collection of published data from forested land, we find that a low litter carbon-to-nitrogen ratio(C/N) and high wetness index(P/PET, precipitation-to-potentialevapotranspiration ratio) are the two factors that promote SOC accumulation, with only minor contributions of litter quantity and soil texture. The field survey data demonstrated that high plant diversity decreased litter C/N and thus indirectly promoted SOC accumulation by increasing the litter quality. We conclude that any changes in plant-community composition, plant-species richness and environmental factors that can reduce the litter C/N ratio, or climatic changes that increase wetness index, may promote SOC accumulation. The study provides a guideline for modeling the carbon cycle of various ecosystem scales and formulates the principle for land-based actions for mitigating the rising atmospheric CO2 concentration.Guoyi Zhou Shan Xu Philippe Ciais Stefano Manzoni Jingyun Fang Guirui Yu Xuli Tang Ping Zhou Wantong Wang Junhua Yan Gengxu Wang Keping Ma Shenggong Li Sheng Du Shijie Han Youxin Ma Deqiang Zhang Juxiu Liu Shizhong Liu Guowei Chu Qianmei Zhang Yuelin Li Wenjuan Huang Hai Ren Xiankai Lu Xiuzhi Chen 2019National Science Review2019,6,4:21
3Poor outcomes of immunoglobulin D multiple myeloma patients in the era of novel agents:a single-center experience显示文摘Dear Editor, Multiple myeloma (MM) is a disease characterized by the clonal expansion of malignant plasma cells in the marrow, leading to anemia, hypercalcemia, bone lesion, and renal dysfunction [1]. Immunoglobulin D (IgD) myeloma is a rare subtype of MM, accounting for approximately 1% to 2% of all MM patients [2]. It occurs at a young age, often accom-panied with a high disease burden and short median sur-vival (18-21 months) [3, 4]. Several studies have suggested that in patients with IgD subtype, the outcomes of those who have had undergone autologous stem cell transplanta-tion (ASCT) were superior than those treated with chemo-therapy alone [5, 6]. However, these have been debatable as other reports have displayed opposite results [7, 8].Qian Zhao Feng Li Ping Song Xiaogang Zhou Zhiming An Jiangang Mei Jingjing Shao Hanqing Li Xuli Wang Xing Guo Yongping Zhai 2019Cancer Communications2019,39,1:3
4Nanostructured amorphous Fe_(29)Co_(27)Ni_(23)Si_(9)B_(12) high-entropy-alloy:an efficient electrocatalyst for oxygen evolution reaction显示文摘Proximal configu ration of dissimilar metal atoms in amorphous high-entropy-alloys(HEAs) always re sult in interatomic d-band ligand effect,dense defect distribution,coordinatively unsaturated sites,high potential energy,and loose atom bonding.Herein,nanostructured amorphous Fe_(29)Co_(27)Ni_(23)Si_(9)B_(12) HEA ribbon is fabricated via a melt spinning method combined with electrochemical corrosion etching process,which is applied as the potential oxygen evolution reaction electrocatalyst.It is found that there are micro/nano pits on the surface of etched amorphous Fe_(29)Co_(27)Ni_(23)Si_(9)B_(12) ribbons.Various elements of HEAs bond with each other to form a highly disordered configu ration,which could result in an optimized bonding energy and enhanced intrinsic catalytic activity.The electrocatalysis activity measurements indicate that the amorphous HEA endows a much higher activity than the crystalline one,which is further improved by the electrochemical etching treatment.Especially,the HEA ribbon etched for 3 h requires a low overpotential of 230 mV to afford 10 mA cm^(-2) current density.In addition,density functional theory calculations demonstrate that the amorphous structure can weaken the interaction between the surface of Fe_(29)Co_(27)Ni_(23)Si_(9)B_(12) alloy and the intermediates,leading to an optimized adsorption Gibbs free energy.Hongyan Wang Ran Wei Xiumin Li Xuli Ma Xiaogang Hao Guoqing Guan 2021Journal of Materials Science & Technology2021,,9:3
5Brain cell apoptosis and enhancement of nervous excitability in pregnant rats with high plasma levels of homocysteine显示文摘Hyperhomocysteinemia is an important risk factor for preeclampsia-eclampsia. This study established a pregnant rat model of hyperhomocysteinemia, in which blood plasma homocysteine concentrations were twice or three times greater than that of normal pregnant rats. TUNEL revealed an increase in the number of apoptotic cells in the frontal cortex of pregnant rats with hyperhomocysteinemia. In addition,immunohistochemical staining detected activated nuclear factor-κB-positve cells in the frontal cortex.Reverse transcription-PCR detected that mRNA expression of the anti-apoptotic gene bcl-2 diminished in the frontal cortex. In situ hybridization and western blotting revealed that N-methyl-D-aspartate receptor 1 mRNA and protein expression was upregulated in the frontal cortex and hippocampus. These results indicate that hyperhomocysteinemia can induce brain cell apoptosis,increase nerve excitability, and promote the occurrence of preeclampsia in pregnant rats.Jun Wang Jing Ge Liu Yang Haiyan Zhang Xuli Li Dan Xue 2012Neural Regeneration Research2012,7,28:2
6Identification and characterization of cDNA sequences encoding the HIS3 and LEU2 genes of the fungus Alternaria tenuissima显示文摘Alternaria tenuissima is a fungus widely present in the environment and could cause diseases in plants and humans. In this study, through a yeast genetic approach, cDNA sequences were isolated and characterized for the AtHIS3 and AtLEU2 genes. AtHIS3 cDNA encodes a protein of 238 amino acids, while AtLEU2 cDNA encodes a protein of 363 amino acids. Based on the phylogenetic analysis of amino acid sequences of AtHis3p and AtLeu2p, A. tenuissima is closely related to the plant pathogenic fungus Phaeosphaeria nodorum. This study provides two genetic markers for studies of functions of genes regulating development, morphology, and virulence of A. tenuissima.Ying Wan Xuli Wang Yun Huang Dewen Qiu Linghuo Jiang 2008Journal of Genetics and Genomics2008,35,4:2

9Enhanced dynamic deformability and strengthening effect via twinning and microbanding in high density NiCoFeCrMoW high-entropy alloys显示文摘High density alloys with enhanced deformability and strength are urgently required in energy,military and nuclear industries,etc.In this work,we present a new kind of NiCoFeCrMoW high entropy alloys(HEAs)which possess higher densities and sound velocities than copper.We systematically investigate the phase structure,quasi-static tensile,dynamic compression and related deformation mechanism of these HEAs.It is shown that single FCC or FCC+μdual phases were formed in the HEAs depending on Mo and W content and annealing temperature.Excellent quasi-static tensile and dynamic compression properties have been achieved for these HEAs,e.g.Ni_(30)Co_(30)Fe_(21)Cr_(10)W_(9)HEA annealed at 1573 K exhibited a yield and ultimate tensile strength and elongation of~364 MPa,~866 MPa and~32%,respectively,in quasi-static test;a yield strength of~710 MPa and no fracture under the dynamic strain rate of 4100 s^(-1).Superior strain rate sensitivity(SRS)of yield strength than that of previously reported FCC HEAs have been evidenced.The dynamic stress-strain constitutive relation can be described by the modified Johnson-Cook model.As for the dynamic deformation mechanism,it is envisaged that the regulation of stacking fault energy and Peierls barrier in current HEAs resulted in occurrences of abundant nanoscale deformation twins and microbands during high strain rate compression.The synergistic microbanding and twinning effectively contributes to the enhanced dynamic deformability and strengthening effect.Besides,the interactions of dislocations with precipitates,stacking faults(SFs)with twins,and between SFs also contribute to extraordinary work-hardening capacity.Xuli Liu Yidong Wu Yansong Wang Jinbin Chen Rui Bai Lei Gao Zhe Xu William Yi Wang Chengwen Tan Xidong Hui 2022Journal of Materials Science & Technology2022,,32:1

12Clinicopathological features of hypoxia-inducible factor-1α and vascular endothelial growth factor expression in patients with lung cancer显示文摘Objective The aim of the study was to investigate the clinicopathological characteristics of hypoxiainducible factor-1α(HIF-1α) and vascular endothelial growth factor(VEGF) expression in patients with lung cancer.Methods Cancerous and noncancerous tissues were collected post-operation from 115 patients with lung cancers by the self-control method. Total RNA was extracted from the lung tissues. The status of tissue HIF-1α expression and intercellular distribution was observed by immunochemistry using a tissue microarray. The expression levels of circulating HIF-1α and VEGF were detected by enzyme-linked immunosorbent assay(ELISA).Results The expression of serum HIF-1α [(138.3 ± 28.8) μg/L] in the group of patients with lung cancer was significantly higher(P < 0.01) than that in the group of patients with pneumonia [(58.8 ± 14.5) μg/L] and the control group of patients ((24.1 ± 3.3) μg/L)There was a strong positive correlation of serum HIF-1α levels(r = 0.937, P < 0.01) with serum VEGF levels. The specific concentration of total RNA [(1.52 ± 1.14) μg/mg wet lung tissues] in the cancerous tissues was significantly higher(t = 8.494, P < 0.001) than that in the noncancerous tissues ((0.58 ± 0.33) μg/mg)The clinicopathological features of HIF-1α expression in lung cancer tissues revealed a significant relationship between positive HIF-1α expression and patient sex(χ~2 = 4.494, P = 0.034), tumor size(χ~2 = 4.679, P = 0.031), differentiation degree(χ~2= 8.846, P = 0.012), and presence of lymphatic node metastasis(χ~2= 6.604, P = 0.037).Conclusion Abnormal HIF-1α expression in lung cancer is closely related with nucleic acid metabolism and angiogenesis, and it may be helpful in the diagnosis and identification of lung cancer.Xuli Yang Li Wang Wenli Sai Yin Cai Juanjuan Gu Xin Chen Dengfu Yao 2016Oncology and Translational Medicine2016,2,6:1

19Optimization of Sample Pretreatment for Determination of Polycyclic Aromatic Hydrocarbons in Estuarine Sediments by Gas Chromatography显示文摘This study examined levels of polycyclic aromatic hydrocarbons (PAHs) in estuarine sediments in Licun (Qingdao, China) by gas chromatography under optimized conditions for sample pretreatment via ultrasonic extraction, column chromatography, and thin layer chromatography. Methanol and dichloromethane (DCM)/methanol (2:1, v/v) were used in ultrasonic extraction, and DCM was used as eluate for column chromatography. The developing system consisted of n-hexane and DCM at a ratio of 9:1 (v/v), with DCM as the extraction solvent for PAHs-containing silica gel scraped off the plate. When the spiking level is 100 ng, total recoveries of spiked matrices for four target PAHs (phenanthrene, anthracene, pyrene and chrysene) were 83.7%, 76.4%, 85.8%, and 88.7%, respectively, with relative standard deviation (RSD) between 5.0% and 6.5% (n = 4). When the spiking level is 1000 ng, associated total recoveries were 78.6%, 72.7%, 82.7% and 85.3%, respectively, with RSD between 4.4% and 5.3% (n = 4). The opti-mized method was advantageous for determination of PAHs in complex matrix due to its effective sample purification.WANG Yan LI Xianguo PENG Xuewei TANG Xuli DENG Xiaoyan 2012Journal of Ocean University of China2012,11,2:1
