| 1 | Climate 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 | 2019 | National Science Review2019，6，4： | 21 |
| 2 | Poor 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 | 2019 | Cancer Communications2019，39，1： | 3 |

| 4 | Nanostructured 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 | 2021 | Journal of Materials Science & Technology2021，，9： | 3 |
| 5 | Brain 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 | 2012 | Neural Regeneration Research2012，7，28： | 2 |

| 10 | Clinicopathological 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 | 2016 | Oncology and Translational Medicine2016，2，6： | 1 |

| 15 | Optimization 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 | 2012 | Journal of Ocean University of China2012，11，2： | 1 |

| 17 | Isolation and characterization of melanin from rapeseed meal显示文摘Melanin involves in various biological functions, widely used in cosmetic, pharmacology medicine and other fields. However, melanin application is limited due to low productivity and high cost. In this work, melanin extraction method from rapeseed meal(RSM) was explored. Effects of hydrochloric acid(HCl) concentration, ethanol concentration, extraction temperature and time, and solid-liquid ratio were evaluated systematically. According to results of single factor experiment and Box-Behnken experiment, the optimum extraction conditions of melanin from RSM were as follows: HCl concentration, 0.5 mol/L; ethanol concentration, 70%; extraction temperature, 40 o C; extraction time, 1 h; solid liquid ratio, 1/4 g/mL. Under these conditions, extraction yields of crude melanin(CM) and purified melanin(PM) were 9.00% and 1.44%, respectively. Compared with synthetic melanin(SM) from Sigma, the relative purities of CM and PM were 7.82% and 29.57%, respectively. Moreover, feedstuff value of RSM residue was also improved after melanin isolation by significantly reducing glucosinolate content. | Xuli Ma Xuan Li Fan Chen Wenchao Chen Xia Wan Fenghong Huang | 2019 | Oil Crop Science2019，4，1： | 0 |
| 18 | Programmable dual responsive system reconstructing nerve interaction with small-diameter tissue-engineered vascular grafts and inhibiting intimal hyperplasia in diabetes显示文摘Small-diameter tissue-engineered vascular grafts(sdTEVGs)with hyperglycemia resistance have not been constructed.The intimal hyperplasia caused by hyperglycemia remains problem to hinder the patency of sdTEVGs.Here,inspired by bionic regulation of nerve on vascular,we found the released neural exosomes could inhibit the abnormal phenotype transformation of vascular smooth muscle cells(VSMCs).The transformation was a prime culprit causing the intimal hyperplasia of sdTEVGs.To address this concern,sdTEVGs were modified with an on-demand programmable dual-responsive system of ultrathin hydrogels.An external primary Reactive Oxygen Species(ROS)-responsive Netrin-1 system was initially triggered by local inflammation to induce nerve remolding of the sdTEVGs overcoming the difficulty of nerve regeneration under hyperglycemia.Then,the internal secondary ATP-responsive DENND1A(guanine nucleotide exchange factor)system was turned on by the neurotransmitter ATP from the immigrated nerve fibers to stimulate effective release of neural exosomes.The results showed nerve fibers grow into the sdTEVGs in diabetic rats 30 days after transplantation.At day 90,the abnormal VSMCs phenotype was not detected in the sdTEVGs,which maintained long-time patency without intima hyperplasia.Our study provides new insights to construct vascular grafts resisting hyperglycemia damage. | Yanzhao Li Yeqin Wang Fangchao Xue Xuli Feng Zhaojing Ba Junjie Chen Zhenhua Zhou Yanhong Wang Ge Guan Guanyuan Yang Ziwei Xi Hao Tian Yong Liu Ju Tan Gang Li Xiewan Chen Mingcan Yang Wen Chen Chuhong Zhu Wen Zeng | 2022 | Bioactive Materials2022，7，1： | 0 |

| 20 | Optimized One-Step Preparation of a Bioactive Natural Product,Guaiazulene-2,9-dione显示文摘We previously isolated a natural product, namely guaiazulene-2,9-dione showing strong antibacterial activity against Vibrio anguillarum, from a gorgonian Muriceides collaris collected in South China Sea. In this experiment, guaiazulene-2,9-dione was quantitatively synthesized with an optimized one-step bromine oxidation method using guaiazulene as the raw material. The key reaction condition including reaction time and temperature, drop rate of bromine, concentration of aqueous THF solution, respective molar ratio of guaiazulene to bromine and acetic acid, and concentration of guaiazulene in aqueous THF solution, were investigated individually at five levels each for optimization. Combined with the verification test to show the absolute yield of each optimization step, the final optimal condition was determined as: when a solution of 0.025 mmol m L-1 guaiazulene in 80% aqueous THF was treated with four volumes of bromine at a drop rate of 0.1 m L min-1 and four volumes of acetic acid at-5℃ for three hours, the yield of guaiazulene-2,9-dione was 23.72%. This was the first report concerning optimized one-step synthesis to provide a convenient method for the large preparation of guaiazulene-2,9-dione. | CHENG Canling LI Pinglin WANG Wei SHI Xuefeng ZHANG Gang ZHU Hongyan WU Rongcui TANG Xuli LI Guoqiang | 2014 | Journal of Ocean University of China2014，13，6： | 0 |
