| 1 | Functional exhaustion of antiviral lymphocytes in COVID-19 patients显示文摘In December 2019,a novel coronavirus was first reported in Wuhan,China.1 It was named by the World Health Organization as severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and is responsible for coronavirus disease 2019(COVID-19).Up to 28 February 2020,79,394 cases have been confirmed according to China’s National Health Commission.Outside China,the virus has spread rapidly to over 36 countries and territories. | Yuanhong Xuand Zhigang Tian Meijuan Zheng Yong Gao Gang Wang Guobin Song Siyu Liu Dandan Sun Yuanhong Xu Zhigang Tian | 2020 | Cellular & Molecular Immunology2020，17，5： | 54 |
| 2 | Effects of land-use types on the vertical distribution of fractions of oxidizable organic carbon on the Loess Plateau, China显示文摘The oxidizability of soil organic carbon(SOC_) influences soil quality and carbon sequestration. Four fractions of oxidizable organic carbon(very labile(C_1), labile(C_2), less labile(C_3) and non-labile(C_4)) reflect the status and composition of SOC_ and have implications for the change and retention of SOC_. Studies of the fractions of oxidizable organic carbon(OC_) have been limited to shallow soil depths and agroecosystems. How these fractions respond at deep soil depths and in other types of land-use is not clear. In this study, we evaluated the vertical distributions of the fractions of oxidizable organic carbon to a soil depth of 5.0 m in 10 land-use types in the Zhifanggou Watershed on the Loess Plateau, C_hina. Along the soil profile, C_1 contents were highly variable in the natural grassland and shrubland I(C_aragana microphylla), C_2 and C_4 contents were highly variable in the natural grassland and two terraced croplands, respectively, and C_3 contents varied little. Among the land-use types, natural grassland had the highest C__1 and C_2 contents in the 0–0.4 m layers, followed by shrubland I in the 0–0.1 m layer. Natural grassland had the highest C_4 contents in the 1.0–4.5 m layers. Natural grassland and shrubland I thus contributed to improve the oxidizability of SOC_ in shallow soil, and the deep soil of natural grassland has a large potential to sequester SOC_ on the Loess Plateau. | SUN Caili XUE Sha CHAI Zongzheng ZHANG Chao LIU Guobin | 2016 | Journal of Arid Land2016，8，2： | 5 |
| 3 | Natural vegetation restoration of Liaodong oak(Quercus liaotungensis Koidz.) forests rapidly increased the content and ratio of inert carbon in soil macroaggregates显示文摘The lack of clarity of how natural vegetation restoration influences soil organic carbon(SOC) content and SOC components in soil aggregate fractions limits the understanding of SOC sequestration and turnover in forest ecosystems.The aim of this study was to explore how natural vegetation restoration affects the SOC content and ratio of SOC components in soil macroaggregates(>250 μm), microaggregates(53–250 μm), and silt and clay(<53 μm) fractions in 30-, 60-, 90-and 120-year-old Liaodong oak(Quercus liaotungensis Koidz.) forests, Shaanxi, China in 2015.And the associated effects of biomasses of leaf litter and different sizes of roots(0–0.5, 0.5–1.0, 1.0–2.0 and >2.0 mm diameter) on SOC components were studied too.Results showed that the contents of high activated carbon(HAC), activated carbon(AC) and inert carbon(IC) in the macroaggregates, microaggregates and silt and clay fractions increased with restoration ages.Moreover, IC content in the microaggregates in topsoil(0–20 cm) rapidly increased;peaking in the 90-year-old restored forest, and was 5.74 times higher than AC content.In deep soil(20–80 cm), IC content was 3.58 times that of AC content.Biomasses of 0.5–1.0 mm diameter roots and leaf litter affected the content of aggregate fractions in topsoil, while the biomass of >2.0 mm diameter roots affected the content of aggregate fractions in deep soil.Across the soil profiles, macroaggregates had the highest capacity for HAC sequestration.The effects of restoration ages on soil aggregate fractions and SOC content were less in deep soil than in topsoil.In conclusion, natural vegetation restoration of Liaodong oak forests improved the contents of SOC, especially IC within topsoil and deep soil.The influence of IC on aggregate stability was greater than the other SOC components, and the aggregate stability was significantly affected by the biomasses of litter, 0.5–1.0 mm diameter roots in topsoil and >2.0 mm diameter roots in deep soil.Natural vegetation restoration of Liaodong oak forests promoted SOC sequestration by soil macroaggregates. | SUN Lipeng HE Lirong WANG Guoliang JING Hang LIU Guobin | 2019 | Journal of Arid Land2019，11，6： | 5 |
| 4 | Application of the oblique ionogram as vertical ionogram显示文摘The vertical ionogram can provide the important ionospheric parameters, such as critical frequency, virtual height and electron density, for ionospheric research. The oblique ionosonde has the ability to detect the ionosphere over sea and other terrain where it is not practical to deploy vertical sounder and provide more ionograms with less transmitting and receiving devices. Therefore, the conversion of the oblique ionogram to vertical ionogram for obtaining the important ionospheric parameters is a very useful inversion technology. The experimental comparison between oblique and vertical detections was carried out in the equatorial ionospheric anomaly (EIA) region of south China on 25 and 26 August 2010. The oblique detecting path was from Wuhan to Shenzhen and the VI ionosonde was located in the midpoint of the oblique path. The oblique ionogram reversion results showed a small deviation of the critical frequency, minimum virtual height as well as the electron density profile of the ionospheric F layer, as compared with the real vertical observations. | CHEN Gang ZHAO ZhengYu ZHANG YuanNong YANG GuoBin ZHOU Chen HUANG Shuo LI Ting LI Ning SUN HengQing | 2012 | Science China(Technological Sciences)2012，55，5： | 5 |
| 5 | The analysis of genetic diversity and differentiation of six Chinese cattle populations using microsatellite markers显示文摘A total of 321 individuals from six cattle populations of four species in a bovine subfamily in China were studied using 12 pairs of mi- crosatellite markers. The genetic diversities within and between populations were calculated. The phylogenetic trees were constructed by (δμ) 2 and DA distances, and the divergence times between populations were estimated by (δμ) 2. Altogether, 144 microsatellite alleles were detected including 24 private alleles and nine shared alleles. Chinese Holstein had the largest number of private alleles (10), whereas, Bohai black and Buffalo had the smallest number of private alleles (2). Chinese Holstein showed the highest genetic variability. Its ob- served number of alleles (Na), mean effective number of alleles (MNA), and mean heterozygosity (He) were 7.7500, 4.9722, and 0.7719, respectively, whereas, the Buffalo and Yak showed low genetic variability. In the phylogenetic trees, Luxi and Holstein grouped first, followed by Bohai and Minnan. Yak branched next and buffalo emerged as the most divergent population from other cattle populations. Luxi and Bohai were estimated to have diverged 0.039-0.105 million years ago (MYA), however, buffalo and Holstein diverged 0.501-1.337 MYA. The divergence time of Yak versus Minnan, Holstein and buffalo was 0.136-0.363, 0.273-0.729, and 0.326-0.600 MYA, respectively. | Yongjiang Mao Hong Chang Zhangping Yang Liu Zhang Ming Xu Guobin Chang Wei Sun Guangming Song Dejun Ji | 2008 | Journal of Genetics and Genomics2008，35，1： | 2 |

| 12 | Charge density wave phase suppression in 1T-TiSe_(2) through Sn intercalation显示文摘Taking advantage of the unique layered structure of TiSe2,the intrinsic electronic properties of two-dimensional materials can easily be tuned via heteroatomic engineering.Herein,we show that the charge density wave(CDW)phase in 1T-TiSe_(2) single-crystals can be gradually suppressed through Sn atoms intercalation.Using angle-resolved photoemission spectroscopy(ARPES)and temperature-dependent resistivity measurements,this work reveals that Sn atoms can induce charge doping and modulate the intrinsic electronic properties in the host 1T-TiSe_(2).Notably,our temperature-dependent ARPES results highlight the role exciton-phonon interaction and the Jahn-Teller mechanism through the formation of backfolded bands and exhibition of a downward Se shift of 4p valence band in the formation of CDW in this material. | Mukhtar Lawan Adam Hongen Zhu Zhanfeng Liu Shengtao Cui Pengjun Zhang Yi Liu Guobin Zhang Xiaojun Wu Zhe Sun Li Song | 2022 | Nano Research2022，15，3： | 1 |

| 15 | Numerical Study on Heat Transfer and Flow Characteristics for Laminar Flow in a Circular Tube with Swirl Generators显示文摘This study investigated the heat transfer and flow characteristics of one kind of swirlgenerator in a circular heat exchanger tube through a numericalsimulation. The swirlflow induced by this type of swirlgenerator can obtain a high heat transfer rate with minimalpressure drop penalty. The simulations were carried out to understand the physicalbehavior of this kind of mesoscale heat enhancement component. By visualizing the heat transfer and flow characteristics, it is found that the swirlflow is induced by swirlgenerator in the circular tube couples with the impinging jet effect. After passing through the swirlgenerator, the localfriction factor of liquid can quickly return to lower levelmore quickly, while the localNusselt number maintains higher values for a distance; thus, the evaluation criterion of localperformance is improved. Single-factor optimization is used for three geometric parameters, i.e., the angle of swirlgenerator(25o, 45o, and 60o), the length of swirlgenerator(0.005, 0.01, and 0.02 m), and the center rod radius(1, 2, and 3 mm). The optimum parameters of the swirlgenerator for laminar flow of air in a circular tube are obtained, which should be 60o, 0.005 m, and 3 mm, respectively. | Yongli Sun Guobin Wen Xiaoming Xiao Bohua Ren Na Yang Luhong Zhang | 2018 | Transactions of Tianjin University2018，24，3： | 1 |

| 19 | A non-rigid shift of band dispersions induced by Cu intercalation in 2H-TaSe2显示文摘The intercalation of metal is a promising method for the modulating electronic properties in transition metal dichalcogenides(TMDs).However,there still lacks enough knowledge about how the intercalated atoms directly impact the two-dimensional structural layers and modulate the band structures therein.Taking advantage of X-ray absorption fine structure and angle-resolved photoemission spectroscopy,we studied how Cu intercalation influences the host TaSe2 layers in Cu0.03TaSe2 crystals.The intercalated Cu atoms form bonds with Se of the host layers,and there is charge transfer from Cu to Se.By examining the changes of band dispersions,we show that the variation of electronic structures is beyond a simple rigid band model with merely charge doping effect.This work'reveals that the unusual change of band dispersions is associated with the formation of bonds between the intercalated metal elements and anion ions in the host layers,and provides a reference for the comprehensive understanding of the electronic structures in intercalated materials. | Pengdong Wang Rashid Khan Zhanfeng Liu Bo Zhang Yuliang Li Sheng Wang Yunbo Wu Hongen Zhu Yi Liu Guobin Zhang Dayong Liu Shuangming Chen Li Song Zhe Sun | 2020 | Nano Research2020，13，2： | 0 |
| 20 | Fasting Blood Glucose but not TMAO is Associated with in-Stent Restenosis in Patients with Acute Coronary Syndrome显示文摘Background:The purpose of our study was to assess whether the occurrence of ISR might be associated with plasma TMAO levels in patients with ACS after DES implantation.Methods:This was a single center retrospective case-control study,in which 64 symptomatic patients with repeated coronary angiography after PCI and 15 patients with ISR were included in the ISR group,and 49 patients without ISR were included in the non-ISR group.High-performance liquid chromatography with tandem mass spectrometry was used to measure plasma TMAO levels.Results:No significant differences were observed in plasma TMAO between the ISR and non-ISR groups.Plasma TMAO levels showed no significant correlation with ISR,but were significantly positively correlated with diabetes mellitus,serum HbA1c levels and serum creatinine levels;moreover,they were significantly negatively correlated with female sex.ISR was significantly positively correlated with diabetes mellitus,fasting blood glucose levels,the neutro-phil to lymphocyte ratio and syntax score;in addition,it was significantly negatively correlated with platelets.Logistic regression analysis indicated that fasting blood glucose was the only independent predictor of ISR.Conclusion:Plasma TMAO may not be associated with ISR and plaque burden in patients with ACS after DES im-plantation,whereas FBG may predict the development of ISR in these patients. | Boda Zhou Yajun Xue Jie Zhou Shenjie Sun Tingting Lv Ou Zhang Yu Geng Guobin Miao Ping Zhang | 2022 | Cardiovascular Innovations and Applications2022，，1： | 0 |
