| 1 | Paleogene-Neogene stratigraphic realm and sedimentary sequence of the Qinghai-Tibet Plateau and their response to uplift of the plateau显示文摘Based on the data of 1:250000 geological mapping completed by CGS and the previous literature of the Cenozoic strata, 98 remnant basins and 5 stratigraphic realms with 13 stratigraphic subrealms have been recognized on the Qinghai-Tibet Plateau and its adjacent area. Through the research of the types of remnant basins, tectonic setting, stratigraphic sequence and sedimentary characteristics, contact relationship between the strata, the formation time and evolution history of sediments, we divided the uplift process and sedimentary response of the Qinghai-Tibet Plateau into 3 stages and 8 sub-stages, namely, subduction-collision uplift stage (65-34 Ma) with three sub-stages, intercontinental convergence and compressive uplift stage (34-13 Ma) with three sub-stages, and intercontinental isostatic adjustment uplift stage (since 13 Ma) with two sub-stages. | ZHANG KeXin WANG GuoCan JI JunLiang LUO ManSheng KOU XiaoHu WANG YueMing XU YaDong CHEN FenNing CHEN RuiMing SONG BoWen ZHANG JianYu LIANG YinPing | 2010 | Science China Earth Sciences2010，53，9： | 49 |
| 2 | Cenozoic sedimentary records and geochronological constraints of differential uplift of the Qinghai-Tibet Plateau显示文摘Geological mapping data (1:250000) in the Qinghai-Tibet Plateau and its adjacent regions reveal the sediment sequences, distribution and tectonic evolution of the 92 Tertiary remnant basins. Southern Tibet and the Yecheng area in Xinjiang, located at southern and northwestern margins of the Qinghai-Tibet Plateau, respectively, were parts of the Neo-Tethys remnant sea in the Paleogene. In southern Tibet, both the subabyssal and abyssal sequences occur at the Gyangze, Saga, Guoyala, and Sangmai areas. The deep-water facies successions outcrop in the west, whereas the shallow-water facies sequences in the east, indicating the east to the west retreat of the Neo-Tethys Ocean. The retreat of the Neo-Tethys Ocean in the east was contributed to the earlier tectonic uplift of the eastern Qinghai-Tibet Plateau. The uplift process of the Plateau from the Late Cretaceous to Pliocene is described as follows: During the Late Cretaceous, tectonic uplift of the Qinghai-Tibet Plateau occurred in the northeastern part and the configuration of the Qinghai-Tibet Plateau was characterized by rise in the northeast and depression in the west. In the Paleocene-Eocene interval, the Tengchong-Baingoin and Kuyake-Golmud areas experienced local tectonic uplifting, the West Kunlun uplift zone broadened easterly, the Qilian uplift zone broadened southerly, and the Songpan-Garzê uplift zone shrank easterly. The Oligocene configuration of the Qinghai-Tibet Plateau was characterized by mountain chains rising along its margins and sedimentary basins in the central part because of tectonic uplifts of the Gangdisê and the Himalaya blocks. Meanwhile, the Kunlun-Altyn-Qilian uplift zones have also broadened southerly and northerly. In contrast, the great uplift zones of the Gangdisê, the Himalaya, the Karakorum, and the Kunlun blocks characterize the paleogeographic contours of the Qinghai-Tibet Plateau during the Miocene-Pliocene. Additionally, the thermochronological data on tectonic uplift events in southern Tibet, West Kunlun Mountains, Altyn Tagh, eastern Tibet, and western Sichuan all suggest that the most intense deformation occurred at 13-8 Ma and since 5 Ma, respectively, corresponding to two great uplift periods in Neogene. As a result, turnover of paleogeographic configuration of the Qinghai-Tibet Plateau occurred during the Neogene, experiencing a change from high contours in the east in the pre-Oligocene to high contours in the west at the end-Pliocene. The uplift of the Qinghai-Tibet Plateau during the Cenozoic was episodic, and the uplifts of various blocks within the Plateau were spatially and chronologically different. | ZHANG KeXin WANG GuoCan CAO Kai LIU Chao XIANG ShuYuan HONG HanLie KOU XiaoHu XU YaDong CHEN FenNing MENG YanNing CHEN RuiMing | 2008 | Science China Earth Sciences2008，51，11： | 31 |
| 3 | The Sedimentary Record in Northern Qaidam Basin and its Response to the Uplift of the South Qilian Mountain at around 30 Ma显示文摘The thick, Eocene to Pliocene, sedimentary sequence in Qaidam Basin at the northern margin of the Tibetan Plateau records the surface uplift history of the northeastern Tibetan plateau. In this study, we present detailed geochemistry, heavy mineral, and clay mineralogy data of the well preserved sedimentary record in the Dahongou section in the northeast of the Qaidam Basin. The results suggest that the sedimentary sequence recorded a 30 Ma young uplift/unroofing event in the northern edge of the Qaidam Basin, which is characterized by high ZTR index value and chlorite content, and low CIW`. The results are consistent with previous sedimentological studies of the Qaidam Basin, which indicated rapid increase of the accumulation rates around 30 Ma. Based on past thermochronological data from the mountains around the Qaidam Basin and the accumulation rates of the Cenozoic basins in the northeastern Tibetan Plateau, we infer a regional uplift and denudation event along the northeastern Tibetan Plateau during early Oligocene (~30 Ma), indicating that the Tibetan Plateau had expanded north-eastward of the study area at that time. | SONG Bowen ZHANG Kexin CHEN Ruiming WANG Chaowen LUO Mansheng ZHANG Jianyu JIANG Shangsong | 2013 | Acta Geologica Sinica(English Edition)2013，87，2： | 8 |
| 4 | Peripheral CD4^(+) T cell signatures in predicting the responses to anti-PD-1/PD-L1 monotherapy for Chinese advanced non-small cell lung cancer显示文摘Limited benefit population of immune checkpoint inhibitors makes it urgent to screen predictive biomarkers for stratifying the patients.Herein,we have investigated peripheral CD4^(+) T cell signatures in advanced non-small cell lung cancer(NSCLC)patients receiving anti-PD-1/PD-L1 treatments.It was found that the percentages of IFN-γand IL-17A secreting naïve CD4^(+) T cells(Tn),and memory CD4^(+) T cells(Tm)expressing PD-1,PD-L1 and CTLA-4 were significantly higher in responder(R)than non-responder(NonR)NSCLC patients associated with a longer progression free survival(PFS).Logistic regression analysis revealed that the baseline IFN-γ-producing CD4^(+) Tn cells and PD-1^(+)CD4^(+) Tm cells were the most significant signatures with the area under curve(AUC)value reaching 0.849.This was further validated in another anti-PD-1 monotherapy cohort.Conversely,high percentage of CTLA-4^(+)CD4^(+) Tm cells was associated with a shorter PFS in patients receiving anti-PD-L1 monotherapy.Our study therefore elucidates the significance of functional CD4^(+) Tn and Tm subpopulations before the treatment in predicting the responses to anti-PD-1 treatment in Chinese NSCLC patients.The fact that there display distinct CD4^(+) T cell signatures in the prediction to anti-PD-1 and anti-PD-L1 monotherapy from our study provides preliminary evidence on the feasibility of anti-PD-1 and anti-PD-L1 combination therapy for advanced NSCLC patients. | Liliang Xia Hui Wang Mingjiao Sun Yi Yang Chengcheng Yao Sheng He Huangqi Duan Weimin Xia Ruiming Sun Yaxian Yao Zhiwei Chen Qiong Zhao Hong Li Shun Lu Ying Wang | 2021 | Science China(Life Sciences)2021，64，10： | 7 |
| 5 | Sedimentary Evolution of the Qinghai-Tibet Plateau in Cenozoic and its Response to the Uplift of the Plateau显示文摘We have studied the evolution of the tectonic lithofacies paleogeography of Paleocene-Eocene, Oligocene, Miocene, and Pliocene of the Qinghai-Tibet Plateau by compiling data regarding the type, tectonic setting, and lithostratigraphic sequence of 98 remnant basins in the plateau area. Our results can be summarized as follows. (1) The Paleocene to Eocene is characterized by uplift and erosion in the Songpan-Garzê and Gangdisê belts, depression (lakes and pluvial plains) in eastern Tarim, Qaidam, Qiangtang, and Hoh Xil, and the Neo-Tethys Sea in the western and southern Qinghai-Tibet Plateau. (2) The Oligocene is characterized by uplift in the Gangdisê-Himalaya and Karakorum regions (marked by the absence of sedimentation), fluvial transport (originating eastward and flowing westward) in the Brahmaputra region (marked by the deposition of Dazhuka conglomerate), uplift and erosion in western Kunlun and Songpan-Garzê, and depression (lakes) in the Tarim, Qaidam, Qiangtang, and Hoh Xil. The Oligocene is further characterized by depressional littoral and neritic basins in southwestern Tarim, with marine facies deposition ceasing at the end of the Oligocene. (3) For the Miocene, a widespread regional unconformity (ca. 23 Ma) in and adjacent to the plateau indicates comprehensive uplift of the plateau. This period is characterized by depressions (lakes) in the Tarim, Qaidam, Xining-Nanzhou, Qiangtang, and Hoh Xil. Lacustrine facies deposition expanded to peak in and adjacent to the plateau ca. 18-13 Ma, and north-south fault basins formed in southern Tibet ca. 13-10 Ma. All of these features indicate that the plateau uplifted to its peak and began to collapse. (4) Uplift and erosion occurred during the Pliocene in most parts of the plateau, except in the Hoh Xil-Qiangtang, Tarim, and Qaidam. The continuous uplift and intensive taphrogeny in the plateau divided the original large basin into small basins, deposition of lacustrine facies decreased considerably, and boulderstone accumulated, indicating a response to the overall uplift of the plateau. Here, we discuss the evolution of tectonic lithofacies paleogeography in Cenozoic and its response to the tectonic uplift of the Qinghai-Tibet Plateau in relation to the above characteristics. We have recognized five major uplift events, which occurred during 58-53 Ma, 45-30 Ma, 25-20 Ma, 13-7 Ma, and since 5 Ma. The results presented here indicate that the paleogeomorphic configurations of the Qinghai-Tibet Plateau turned over during the late Miocene, with high elevations in the east during the pre-Miocene switching to high contours in the west at the end of Miocene. | ZHANG Kexin WANG Guocan XU Yadong LUO Mansheng JI Junliang XIAO Guoqiao WANG An SONG Bowen LIANG Yinpin JIANG Shangsong CAO Kai CHEN Fenning CHEN Ruiming YANG Yongfeng | 2013 | Acta Geologica Sinica(English Edition)2013，87，2： | 6 |
| 6 | Study on grid adaptability testing methodology for wind turbines显示文摘The use of wind power has grown rapidly in recent years.Wind power is a clean source of energy,but can have negative impacts on the distribution grid.The influence of large-scale wind power integration on the safe and stable operation of a power system cannot be ignored.It is necessary and urgent to achieve grid adaptability for wind turbines in China.Using a 35 kV/6 MVA grid simulator,the performance of a grid is investigated by simulation.Typical grid disturbances such as voltage deviation,frequency fluctuation,voltage unbalance,and distortion can be simulated.A grid adaptability testing methodology was developed and applied to a doubly fed wind turbine with a focus on analyzing real test data to ascertain its three-phase voltage unbalance adaptability,which was successfully demonstrated.The methodology can also be used to guide other grid adaptability tests. | Shaolin LI Shiyao QIN Ruiming WANG Qing LI Chen CHEN | 2013 | Journal of Modern Power Systems and Clean Energy2013，1，1： | 4 |
| 7 | Ship collision impact on the structural load of an offshore wind turbine显示文摘When a maintenance and operations ship is berthing,there is a chance the ship may collide into the wind turbine.When these ships collide into wind turbine structures,this can result in significant changes to the foundation and structure of the wind turbine.In this paper,the structural load of a 4 MW offshore wind turbine was analyzed during a collision with an operations and maintenance ship.The variations in the wind speeds on hub height,waves,and the sea currents were measured.The dynamic simulation of the wind turbine was carried out using the test data as the input parameters.As a result,the load condition of the turbine without a collision was obtained.Finally,the measured turbine load was compared with the simulation results.This study shows that the collision of the operation and the maintenance ship increases the bending moments at the tower’s bottom and the blade’s roots. | Haikun Jia Shiyao Qin Ruiming Wang Yang Xue Deyi Fu Anqing Wang | 2020 | Global Energy Interconnection2020，3，1： | 4 |
| 8 | N,P-codoped porous carbon derived from chitosan with hierarchical N-enriched structure and ultra-high specific surface Area toward high-performance supercapacitors显示文摘In this work,a facile'carbonization-activation'strategy is developed to synthesize N,P-codoped hierarchical porous carbon.Phosphoric acid is innovatively introduced during the hydrothermal process to achieve in-situ P doping as well as create abundant pores,and the employment of sodamide is of vital importance to simultaneously serve as activating agent and N-source to succeed a high-level N doping.Thus,the obtained samples exhibit a unique three-dimensional hierarchical structure with an ultra-high specific surface area(3646 m^(2)g^(-1))and ultra-high N-doping level(9.81 at.%).Computational analyses confirm that N,P co-doping and higher N content can enhance active sites and widen potential differences of carbon materials to improve their capacitance.The as-prepared carbon materials demonstrate superior electrochemical performances,such as an ultra-high capacitance of 586 Fg^(-1)at 1 Ag^(-1),a superior rate capability of 409 Fg^(-1)at 20 Ag^(-1),and excellent long-term stability of 97%capacitance retention after10,000 cycles in 6 M KOH.Moreover,an assembled symmetric supercapacitor delivers a high energy density of 28.1 Wh kg^(-1)at the power density of 450 W kg^(-1)in 1 M Na_(2)SO_(4),demonstrating a great potential for applications in supercapacitors. | Xipeng Xin Na Song Ruiming Jia Bingnan Wang Hongzhou Dong Shuai Ma Lina Sui Yingjie Chen Qian Zhang Lifeng Dong Liyan Yu | 2021 | Journal of Materials Science & Technology2021，，29： | 2 |

| 10 | Mapping of wheat stripe rust resistance gene Yr041133 by BSR-Seq analysis显示文摘Puccinia striiformis Westend. f. sp. tritici(Pst) pathotype CYR34 is widely virulent and prevalent in China.Here, we report identification of a strpie rust resistance(Yr) gene, designated Yr041133, in winter wheat line 041133. This line produced a hypersensitive reaction to CYR34 and conferred resistance to 13 other pathotypes. Resistance to CYR34 in line 041133 was controlled by a single dominant gene. Bulked segregant RNA sequencing(BSR-Seq) was performed on a pair of RNA bulks generated by pooling resistant and susceptible recombinant inbred lines. Yr041133 was mapped to a 1.7 c M genetic interval on the chromosome arm 7 BL that corresponded to a 0.8 Mb physical interval(608.9–609.7 Mb) in the Chinese Spring reference genome. Based on its unique physical location Yr041133 differred from the other Yr genes on this chromosome arm. | Yahui Li Ruiming Lin Jinghuang Hu Xiaohan Shi Dan Qiu Peipei Wu Gebremedhin Habteab Goitom Siqi Wang Hongjun Zhang Li Yang Hongwei Liu Qiuhong Wu Jingzhong Xie Yang Zhou Zhiyong Liu Hongjie Li | 2022 | The Crop Journal2022，10，2： | 1 |

| 13 | Tea Polyphenols Reducing Lipopolysaccharide-induced Inflammatory Responses in RAW264.7 Macrophages via NF-κB Pathway显示文摘The anti-inflammatory activity of tea polyphenols(TPs)in RAW264.7 macrophages stimulated by lipopolysaccharide(LPS)was investigated in this paper.RAW264.7 macrophages were treated with different concentrations of TP(0,12.5,25,50,100,and 200μg/mL)and then stimulated by LPS.Another blank control group was set up.The expression of pro-inflammatory cytokines associated with the nuclear factor-kappa B(NF-κB)signaling pathway was investigated before and after TP treatment.Pretreatment of RAW264.7 cells with TP decreased the expression of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and interleukin 1 beta(IL-1β)pro-inflammatory cytokines.In addition,TP inhibited the phosphorylation of p65 and IκB by blocking the phosphorylation and the degradation of NF-κB inhibitor protein.In conclusion,TP exerts anti-inflammatory effects by regulating the release of inflammatory mediators via the NF-κB signaling pathway. | SU Siyi LI Xiaoyu GUO Xu ZHOU Ruiming LI Manman MING Pengfei HUANG Yingying Sajid Ur RAHMAN DING Hongyan FENG Shibin LI Jinchun WANG Xichun LI Yu WU linjie | 2019 | Chemical Research in Chinese Universities2019，35，6： | 1 |
| 14 | Mesenchymal stromal cells alleviate acute respiratory distress syndrome through the cholinergic anti-inflammatory pathway显示文摘Mesenchymal stromal cells(MSCs)have been considered a promising alternative for treatment of acute respiratory distress syndrome(ARDS).However,there is significant heterogeneity in their therapeutic efficacy,largely owing to the incomplete understanding of the mechanisms underlying the therapeutic activities of MSCs.Here,we hypothesize that the cholinergic antiinflammatory pathway(CAP),which is recognized as a neuroimmunological pathway,may be involved in the therapeutic mechanisms by which MSCs mitigate ARDS.Using lipopolysaccharide(LPS)and bacterial lung inflammation models,we found that inflammatory cell infiltration and Evans blue leakage were reduced and that the expression levels of choline acetyltransferase(ChAT)and vesicular acetylcholine transporter(VAChT)in lung tissue were significantly increased 6 hours after MSC infusion.When the vagus nerve was blocked orα7 nicotinic acetylcholine(ACh)receptor(α7nAChR)-knockout mice were used,the therapeutic effects of MSCs were significantly reduced,suggesting that the CAP may play an important role in the effects of MSCs in ARDS treatment.Our results further showed that MSC-derived prostaglandin E2(PGE2)likely promoted ACh synthesis and release.Additionally,based on the efficacy of nAChR andα7nAChR agonists,we found that lobeline,the nicotinic cholinergic receptor excitation stimulant,may attenuate pulmonary inflammation and alleviate respiratory symptoms of ARDS patients in a clinical study(ChiCTR2100047403).In summary,we reveal a previously unrecognized MSC-mediated mechanism of CAP activation as the means by which MSCs alleviate ARDS-like syndrome,providing insight into the clinical translation of MSCs or CAP-related strategies for the treatment of patients with ARDS. | Xiaoran Zhang Xuxia Wei Yiwen Deng Xiaofeng Yuan Jiahao Shi Weijun Huang Jing Huang Xiaoyong Chen Shuwei Zheng Jieying Chen Keyu Chen Ruiming Xu Hongmiao Wang Weiqiang Li Shiyue Li Huimin Yi Andy Peng Xiang | 2022 | Signal Transduction and Targeted Therapy2022，7，10： | 1 |

| 16 | Blood oxygenation-level dependent functional MRI in evaluating the selective activation of motor cortexes associated with recovery of motor function in hemiplegic patients with ischemic stroke显示文摘BACKGROUND: Previous studies about blood oxygenation-level dependent (BOLD) functional MRI (fMRI) have indicated that the poststroke recovery of motor function is accompanied by the selective activation of motor cortexes with high correlation. OBJECTIVE: To evaluate the short-term outcomes after rehabilitative interventions with BOLD fMRI in hemiplegic patients with acute stroke, and analyze the correlation of the excitement of brain function in the passive and active movements of the affected limb with the recovery of motor function. DESIGN: A case observation. SETTING: Department of Neurology, Baotou Central Hospital. PARTICIPANTS: Thirty hemiplegic inpatients with ischemic stroke were selected from the Department of Neurology, Baotou Central Hospital from January to December in 2005, including 16 males and 14 females, aging 44-71 years with an average age of (56±5) years, and the disease course ranged from 12 to 72 hours. Inclusive criteria: In accordance with the diagnostic standard of ischemic stroke revised by the Fourth National Academic Meeting for Cerebrovascular Disease; Confirmed by cranial CT or MRI. They were all informed agreed with the detected items. METHODS: ① The Bobath technique was adopted in the rehabilitative interventions of the 30 patients, 30 minutes for each time, twice a day for three weeks continuously. ② The hand motor recovery of the stroke patients was graded by the Brunnstrom stages (Ⅰ-Ⅵ), and be able to grasp various objects and extend for the whole range was taken as grade Ⅵ. ③ The patients were examined with fMRI BOLD before rehabilitation and 3 weeks after rehabilitation. All the patients were trained with finger movements, the distracting thoughts should be eliminated as much as possible especially during the movement phase, the patients should highly concentrate on the hand movements. The range for the finger movements should be as large as possible with moderate frequency. The hand movements should be 10 s with an interval of 30 s. Te AVANTO 1.5T MRI machine (Siemens Company, Germany) was used for scanning, the 30 s before fMRI BOLD scanning was the adaptation phase for the patients, and the finger movements were alternated for 6-10 times till the end of the scanning. MAIN OUTCOME MEASURES: Differences after rehabilitation evaluated by the activations of different sensorimotor cortex in the hemiplegic patients with acute stroke. RESULTS: ① In passive and active movements of the affected hand, 5 cases of Brunnstrom grade Ⅰ orⅡ were manifested by the activation of unilateral sensorimotor cortex (SMC) of the hemiplegic side, and they were Brunnstrom grade Ⅱ after 3-week rehabilitation, and 1 case with activations of bilateral SMC recovered to Brunnstrom grade Ⅲ. ② Among the patients of Brunnstrom gradeⅢ or Ⅳ, 5 cases were unilaterally activated, and had no changes after 3-week rehabilitation; Whereas of the 9 cases of bilateral activations, 3 recovered to grade Ⅵ and 6 recovered to grade Ⅴ after 3-week rehabilitation. ③ In the passive and active movements of the affected hand, all the cases of Brunnstrom grades Ⅴ and Ⅵ were manifested by the activations of bilateral SMC. After 3-week rehabilitation, 2 of the 4 cases of grade Ⅴ recovered to grade Ⅵ, and the other 2 recovered to normal; Whereas 5 of the 6 cases of grade Ⅵ recovered to normal, and the other 1 was still grade Ⅵ. CONCLUSION: BOLD fMRI showed that the outcomes of short-term rehabilitation in the patients with bilateral activations were obvious, whereas the outcomes were bad in the patients whose ipsilateral cortexes were activated. The activated signal in ipsilateral or bilateral SMC and the activation of supplementary motor area in active movements were greater than those in the passive ones. | Yuechun Li Guorong Liu Ying He Baojun Wang Furu Liang Li Wang Hui Zhang Jingfen Zhang Ruiming Li Xiaoyan Liu | 2006 | Neural Regeneration Research2006，1，5： | 1 |
| 17 | Twinned substructure in lath martensite of water quenched Fe-0.2%C and Fe-0.8%C steels显示文摘In the present investigation,twinned substructures within lath martensite of two water quenched steels(0.2 wt.%C and 0.8 wt.%C)were studied.The lath martensite has typical hierarchical packet-block-lath with dislocation substructure.Besides,laths that are misoriented by<011>/70.5°or<111>/60° and bordered by{011}plane,namely twinned laths,are observed,of which the density increases and the scale decreases as more carbons were presented.Such twinned laths have body centered cubic(bcc)crystal structure,belonging to twinned variants following the classical Kurdjumov-Sachs(K-S)orientation relationship with respect to the parent austenite.Unlike bcc{112}<111>twins,twinned variants produce strong double diffraction and in turn the extra diffraction spots that are commonly observed in the martensite in steels with wide range of carbon contents. | Haidong Sun Yuhui Wang Zuohua Wang Ning Liu Yan Peng Xiujuan Zhao Ruiming Ren Hongwang Zhang | 2020 | Journal of Materials Science & Technology2020，47，14： | 1 |
| 18 | Advances and challenges of photocatalytic technology for air purification显示文摘With the acceleration of the urban industrialization process,air pollutant emission has increased sharply,which seriously endangers the ecological environment and human beings.Solar-driven photocatalysis has the broad-spectrum activity for various inorganic to organic pollutants at ambient temperature without harsh reaction conditions,which shows a very broad application prospect in air purification.However,the photocatalysis technology suffers from the unrevealed reaction me-chanism and the deactivation of photocatalysts,which severely limits its practical application.Currently,there is still a huge gap between basic research and industrial application in the field of photocatalytic air purification.This review summarizes recent progress on photocatalytic degradation of air pollutants and categorizes them based on the types of photocatalytic materials and air pollutants,with a focus on photocatalytic reaction mechanisms and the application scenarios of photocatalytic air purification to identify this gap.We also critically discussed the major challenges for promoting applications of photo-catalytic technology and put forward the development prospect. | Qin Geng Hong Wang Ruiming Chen Lvcun Chen Kanglu Li Fan Dong | 2022 | National Science Open2022，1，2： | 1 |
