| 3 | Quantitative Assessment on Endangerment Degree of Rare Animal and Plant Species in Tibet,China显示文摘It is of profound theoretical and practical significance to study endangerment status of rare species in Tibet. Index system is firstly set down for quantitative assessment of rare animal and plant species,then endangerment degree of wildlife under special state protection are calculated,which is expressed by value E. The results reveal that Yunnan snub-nosed monkey(Rhinopithecus bieti) ,Himalayan tahr(Hemitragus jemlahicus) and Gigantic Cy-press(Cupressus gigantea) have the highest E respectively in animals and plants. According to value E,all species are catego-rized into 4 ranks:critically endangered(0.6-0.8) ,endangered(0.4-0.6) ,vulnerable(0.2-0.4) and lower risk( E ≤ 0.2) . By compari-son of the first five animals and plants of the highest E,each sub-ecozone bears a distinct identity. | DONG Ke ZHONG Xianghao LIU Shuzhen | 2007 | Wuhan University Journal of Natural Sciences2007，12，4： | 5 |
| 4 | Prognostic significance of combining high mobility group Box-1 and OV-6 expression in hepatocellular carcinoma显示文摘The inflammatory environment and existence of cancer stem cells are critical for progression and intrahepatic recurrence of hepatocellular carcinoma(HCC) after curative resections. Here, we investigated the prognostic significance of combining high mobility group box 1(HMGB1) expression and hepatic progenitor marker OV6 in hepatocellular carcinoma. Expression of HMGB1 and OV6 was evaluated using immunohistochemistry profiling in tissue microarrays containing samples from 208 HCC patients. Invasive clinical or pathological factors were found in patients with high expression of HMGB1 or OV6. Higher HMGB1 was associated with poorer clinical outcomes, and independently related to elevated 5-year recurrence incidence(85.5% vs. 62.4%, P<0.001). We also found that more OV6 positive staining was correlated with poor prognosis of HCC patients(P<0.001). Notably, expression of HMGB1 was positively correlated with OV6 in density(R2=0.032, P<0.001) and reversely related to HCC outcomes. Abnormal expression of HMGB1 in combination with positive staining of OV6 displayed poorer prognostic performance than single biomarker alone(area under curve(AUC) survival=0.696). Therefore, HMGB1 and OV6 positive staining are promising prognostic parameters for HCC, and we propose that HMGB1 and OV6 may cooperate with each other and predict poor prognosis of HCC. | Jihui Zhu Han Yu Shuzhen Chen Pinghua Yang Zihui Dong Yan Ling Hao Tang Shilei Bai Wen Yang Liang Tang Feng Shen Hongyang Wang Wen Wen | 2018 | Science China(Life Sciences)2018，61，8： | 4 |
| 5 | Marine hydrographic spatial-variability and its cause at the northern margin of the Amery Ice Shelf显示文摘Conductivity,temperature and depth(CTD) data collected along a zonal hydrographic section from the northern margin of the Amery Ice Shelf on 25-27 February 2008 by the 24th Chinese National Antarctic Research Expedition (CHINARE) cruise in the 2007/2008 austral summer are analyzed to study thermohaline structures.Analysis reveals warm subsurface water in a limited area around the east end of the northern margin,where the temperature,salinity and density have east-west gradients in the surface layer of the hydrographic section.The localization of the warm subsurface water and the causes of the CTD gradients in the surface layer are discussed.In addition,the results from these CTD data analyses are compared with those from the 22nd CHINARE cruise in the 2005/2006 austral summer.This comparison revealed that the thermoclines and haloclines had deepened and their strengths weakened in the 2007/2008 austral summer.The difference between the two data sets and the cause for it can be reasonably explained and attributed to the change in ocean-ice-atmosphere interactions at the northern margin of the Amery Ice Shelf. | GE RenFeng DONG ZhaoQian CHEN HongXia LIU Na SHI JiuXing PU ShuZhen | 2011 | Advances in Polar Science2011，22，2： | 3 |
| 6 | Molecular characterization of root exudates using Fourier transform ion cyclotron resonance mass spectrometry显示文摘The release of root exudates(REs) provides an important source of soil organic carbon. This work revealed the molecular composition of REs of different plant species including alfalfa( Medicago sativa L.), bean( Phaseolus vulgaris L.), barley( Hordeum vulgare L.), maize( Zea mays), wheat( Triticum aestivum L.), ryegrass( Lolium perenne L.) and pumpkin( Cucurbita maxima) using electrospray ionization coupled with Fourier transform ion cyclotron resonance mass spectrometry(ESI FT-ICR MS). The combination of positive ion mode( + ESI) and negative ion mode(-ESI) increased the number of the molecules detected by ESI FT-ICR MS, and a total of 8758 molecules were identified across all the samples. In detail, lipids and proteins and unsaturated hydrocarbons were more easily detected in + ESI mode, while aromatic compounds with high O/C were readily ionized in-ESI mode, and only 38% of the total assigned formulas were shared by -ESI and + ESI modes. Multivariate statistical analysis of the formulas indicated that the close related plants species secreted REs with similar molecular components. Moreover, the unsaturation degree and nitrogen content were the two key parameters able to distinguish the similarities and differences of molecular components of REs between plant species. The results provided a feasible analysis method for characterization of the molecular components of REs and for the first time characterized the molecular components of REs of a variety of plant species using ESI FT-ICR MS. | Yuexia Miao Jitao Lv Honglin Huang Dong Cao Shuzhen Zhang | 2020 | Journal of Environmental Sciences2020，32，12： | 2 |
| 7 | Plasma metabolomics combined with personalized diagnosis guided by Chinese medicine reveals subtypes of chronic heart failure显示文摘Background:Chronic heart failure(CHF)is characterized by insufficient blood supply from heart to meet the body’s metabolic demands.Integrating Western and traditional Chinese medicine to treat CHF has proved a validated therapeutic approach.In recent years,metabolomics has been regarded as a potential platform to provide biomarkers for diseasesubtypes.Objective:To examine 38 patients,combined NMR plasma metabolomics and traditional Chinese medicine diagnosis in order to identify diagnostic biomarkers for two CHF syndrome subtypes.Methods:After processing the spectra,orthogonal partial least square discriminant analysis was performed,and the contributing NMR signals were analyzed using Y-scrambling statistical validation with good reliability.Results:Plasma metabolic patterns of yin deficiency and yang deficiency patients were clearly discriminated.The yin-deficiency group had increased level of lactate,glycoprotein,lipoprotein and lower levels of glucose,valine and proline.The yang-deficiency group had higher levels of lactate,glycoprotein and pyruvic acid,and lower levels of glucose and lipoprotein.Potential biomarkers of CHF based on the two traditional Chinese medicine syndromes indicated alternative modes of metabolites and metabolic pathways in the disease,e.g.dysfunction of energy utilization and disturbance in fatty acids,amino acids.Conclusion:This study suggests that combining metabolomics with traditional Chinese medicine diagnosis can reveal metabolic signatures for CHF syndrome subtypes.The plasma metabolites identified might be of special clinical relevance for subtypes of CHF,which could lead to further understanding of mechanisms involved and an improvement in personalized treatment for CHF. | Juan Wang Shuzhen Guo Kuo Gao Qi Shi Bangze Fu Chan Chen Liangtao Luo Dong Deng Huihui Zhao Wei Wang | 2015 | Journal of Traditional Chinese Medical Sciences2015，2，2： | 2 |
| 8 | 1064 nm InGaAsP multi-junction laser power converters显示文摘Laser photovoltaic devices converting 1064 nm light energy into electric energy present a promising prospect in wireless energy transmission due to the commercial availability of high power 1064 nm lasers with very small divergence. Besides their high conversion efficiency, a high output voltage is also expected in a laser energy transmission system. Meanwhile,1064 nm InGaAsP multi-junction laser power converters have been developed using p^+-InGaAs/n^+-InGaAs tunnel junctions to connect sub-cells in series to obtain a high output voltage. The triple-junction laser power converter structures are grown on p-type InP substrates by metal-organic chemical vapor deposition(MOCVD), and InGaAsP laser power converters are fabricated by conventional photovoltaic device processing. The room-temperature I–V measurements show that the 1 × 1 cm^2 triplejunction InGaAsP laser power converters demonstrate a conversion efficiency of 32.6% at a power density of 1.1 W/cm^2, with an open-circuit voltage of 2.16 V and a fill factor of 0.74. In this paper, the characteristics of the laser power converters are analyzed and ways to improve the conversion efficiency are discussed. | Jiajing Yin Yurun Sun Shuzhen Yu Yongming Zhao Rongwei Li Jianrong Dong | 2020 | Journal of Semiconductors2020，41，6： | 1 |
| 9 | Aristolochic acids exposure was not the main cause of liver tumorigenesis in adulthood显示文摘Aristolochic acids(AAs) have long been considered as a potent carcinogen due to its nephrotoxicity. Aristolochic acid I(AAI) reacts with DNA to form covalent aristolactam(AL)-DNA adducts,leading to subsequent A to T transversion mutation, commonly referred as AA mutational signature. Previous research inferred that AAs were widely implicated in liver cancer throughout Asia. In this study, we explored whether AAs exposure was the main cause of liver cancer in the context of HBV infection in China's Mainland. Totally 1256 liver cancer samples were randomly retrieved from 3 medical centers and a refined bioanalytical method was used to detect AAI-DNA adducts. 5.10% of these samples could be identified as AAI positive exposure. Whole genome sequencing suggested 8.41% of 107 liver cancer patients exhibited the dominant AA mutational signature, indicating a relatively low overall AAI exposure rate. In animal models, long-term administration of AAI barely increased liver tumorigenesis in adult mice, opposite from its tumor-inducing role when subjected to infant mice. Furthermore, AAI induced dose-dependent accumulation of AA-DNA adduct in target organs in adult mice, with the most detected in kidney instead of liver. Taken together, our data indicate that AA exposure was not the major threat of liver cancer in adulthood. | Shuzhen Chen Yaping Dong Xinming Qi Qiqi Cao Tao Luo Zhaofang Bai Huisi He Zhecai Fan Lingyan Xu Guozhen Xing Chunyu Wang Zhichao Jin Zhixuan Li Lei Chen Yishan Zhong Jiao Wang Jia Ge Xiaohe Xiao Xiuwu Bian Wen Wen Jin Ren Hongyang Wang | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 1 |

| 15 | Health promoting activities and corresponding mechanism of(–)-epicatechin-3-gallate显示文摘(–)-Epicatechin-3-gallate(ECG),a bioactive polyphenolic compound,has contributed a lot to the health benefits of green tea.Great attention has been focused on(–)-epigallocatechin-3-gallate(EGCG),but limited research has been performed towards ECG.Like EGCG,ECG also possesses various pharmacological and physiological properties,such as mediation of antioxidant activities,anti-inflammation response,regulation of cell proliferation and apoptosis,as well as anticancer properties during angiogenesis,invasion and metastasis stages.Nontoxic ECG has various molecular targets within the cells,including CYP enzymes,phaseⅡdetoxification and antioxidant enzymes,as well as pro-inflammatory mediators.The antineoplastic mechanism contains inhibition of phase 1 CYP enzymes,induction of phaseⅡdetoxification and antioxidant enzymes,high anti-inflammatory efficacy,arrest of cell cycle progression,regulation of apoptosis,as well as mediation of metastasis processes.In particular,the gallate moiety of ECG is critical for mediating inhibitory effects towards cancer cells.Besides regulation of intracellular signaling pathways,ECG also inhibits RNase A and matrix metalloproteinase enzymatic activity via chelating metals(copper and zinc)in cancer cells.This review has summarized recent studies on pharmacological properties of ECG,and discussed corresponding mechanism on modulation of cellular signaling events by ECG,hoping to broaden its multiple usage. | Zhiliang Li Changchun Feng Hongjin Dong Weibin Jin Wenying Zhang Jianfeng Zhan Shuzhen Wang | 2022 | Food Science and Human Wellness2022，11，3： | 0 |
| 16 | 1.2 kW all-fiber narrow-linewidth picosecond MOPA system显示文摘Achieving an all-fiber ultra-fast system with above kW average power and mJ pulse energy is extremely challenging.This paper demonstrated a picosecond monolithic master oscillator power amplifier system at a 25 MHz repetition frequency with an average power of approximately 1.2 kW,a pulse energy of approximately 48μJ and a peak power of approximately 0.45 MW.The nonlinear effects were suppressed by adopting a dispersion stretched seed pulse(with a narrow linewidth of 0.052 nm)and a multi-mode master amplifier with an extra-large mode area;then an ultimate narrow bandwidth of 1.32 nm and a moderately broadened pulse of approximately 107 ps were achieved.Meanwhile,the great spatio-temporal stability was verified experimentally,and no sign of transverse mode instability appeared even at the maximum output power.The system has shown great power and energy capability with a sacrificed beam propagation product of 5.28 mm·mrad.In addition,further scaling of the peak power and pulse energy can be achieved by employing a lower repetition and a conventional compressor. | Jiexi Zuo Haijuan Yu Shuzhen Zou Zhiyong Dong Chaojian He Shuang Xu Chaoyu Ning Xuechun Chen Xinyao Li Xuechun Lin | 2023 | High Power Laser Science and Engineering2023，11，2： | 0 |
| 17 | A Preliminary Study on the Phenomenon of Microseismic Fluctuations before Impending Strong Earthquake显示文摘Based on repeated comparison studies of broadband digital seismic records before the Wenchuan MS8. 0,Yushu MS7. 1 and Qingchuan MS5. 4 earthquakes,the possible microseismic fluctuations before impending earthquakes were preliminarily identified. In order to verify and test this phenomenon,a real-time tracking technical system was established by using continuous waveform records of more than 200 wide-band digital seismic stations in regional networks such as Gansu,Qinghai,Sichuan,Yunnan and Tibet.Through real-time tracking and dynamic monitoring of 24 earthquakes with M≥5. 0 occurring in the Qinghai-Tibetan block during the period of 2012-2014 and the observations of stations in some non-seismic areas,the reproducibility and objectivity of the impending earthquake phenomenon were verified. The main characteristics of the microseismic fluctuation phenomena immediately preceding the strong earthquakes are as follows:(1)the spectrum range is wider,the dominant frequency is 11-16 Hz,and the spectrum shape is more regular;(2)it appears 6-24 days before the earthquake,averaging about 15 days;(3)it is possible to be recorded by the stations within the epicenter distance of 50 km,and the stations with the epicenter distance of more than 50 km generally cannot record it;(4)this phenomenon is directional,i. e. the direction in which the activity degree,N-value,varies significantly may be related to the location of the seismic source,the seismogenic fault and the distribution of aftershocks of the strong earthquake. The preliminary study shows that the impending-earthquakes microseismic phenomena may be related to the pre-activity,micro-vibration and micro-rupture in the source region in the imminent stage,or the microactivity and micro-rupture associated with the active tectonics. | YANG Liming HAO Zhen WANG Jianjun ZHANG Shuzhen YAO Jiajun DONG Lei | 2019 | Earthquake Research in China2019，33，3： | 0 |
| 18 | Four-junction AlGaAs/GaAs laser power converter显示文摘Four-junction AlGaAs/GaAs laser power converters (LPCs) with n^+-Ga As/p^+-Al_(0.37)Ga_(0.63)As hetero-structure tunnel junctions (TJs) have been designed and grown by metal-organic chemical vapor deposition(MOCVD) for converting the power of 808 nm lasers. A maximum conversion efficiency ηc of 56.9% ± 4% is obtained for cells with an aperture of 3.14 mm^2 at an input laser power of 0.2 W, while dropping to 43.3% at 1.5 W.Measured current–voltage (I–V) characteristics indicate that the performance of the LPC can be further improved by increasing the tunneling current density of TJs and optimizing the thicknesses of sub-cells to achieve current matching in LPC. | Jie Huang Yurun Sun Yongming Zhao Shuzhen Yu Jianrong Dong Jiping Xue Chi Xue Jin Wang Yunqing Lu Yanwen Ding | 2018 | Journal of Semiconductors2018，39，4： | 0 |
