| 1 | Classification of histological severity of Helicobacter pylori-associated gastritis by confocal laser endomicroscopy显示文摘AIM: To classify the histological severity of Helicobacter pylori (H. pylori) infection-associated gastritis by confocal laser endomicroscopy (CLE). METHODS: Patients with upper gastrointestinal symptoms or individuals who were screened for gastric cancer were enrolled in this study. Histological severity of H. pylori infection-associated gastritis was graded according to the established CLE criteria. Diagnostic value of CLE for histo-logical gastritis was investigated and compared with that of white light endoscopy (WLE). Targeted biopsies from the sites observed by CLE were performed. RESULTS: A total of 118 consecutive patients with H. pylori infection-associated gastritis were enrolled in this study. Receiver operating characteristic curve analysis showedthat the sensitivity and specifi city of CLE were 82.9% and 90.9% for the diagnosis of H. pylori infection, 94.6% and 97.4% for predicting gastric normal mucosa, 98.5% and 94.6% for predicting histological active inflammation, 92.9% and 95.2% for predicting glan-dular atrophy, 98.6% and 100% for diagnosing intes-tinal metaplasia, respectively. Post-CLE image analysis showed that goblet cells and absorptive cells were the two most common parameters on the CLE-diagnosed intestinal metaplasia (IM) images (P < 0.001). More his-tological lesions of the stomach could be found by CLE than by WLE (P < 0.001). CONCLUSION: CLE can accurately show the histological severity of H. pylori infection-associated gastritis. Mapping IM by CLE has a rather good diagnostic accuracy. | Peng Wang Rui Ji Tao Yu Xiu-Li Zuo Chang-Qing Li Zhen Li Yan-Qing Li Cheng-Jun Zhou | 2010 | World Journal of Gastroenterology2010，16，41： | 17 |
| 2 | Microwave Exposure Impairs Synaptic Plasticity in the Rat Hippocampus and PC12 Cells through Over-activation of the NMDA Receptor Signaling Pathway显示文摘Objective The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor(NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment. Methods 48 male Wistar rats were exposed to 30 m W/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 m W/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated. Results Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits(NR1, NR2 A, and NR2B) and related signaling molecules(Ca2+/calmodulin-dependent kinase II gamma and phosphorylated c AMP-response element binding protein) were examined. Conclusion 30 m W/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity. | XIONG Lu SUN Cheng Feng ZHANG Jing GAO Ya Bing WANG Li Feng ZUO Hong Yan WANG Shui Ming ZHOU Hong Mei XU Xin Ping DONG Ji YAO Bin Wei ZHAO Li PENG Rui Yun | 2015 | Biomedical and Environmental Sciences2015，28，1： | 16 |

| 4 | Oroxindin inhibits macrophage NLRP3 inflammasome activation in DSS-induced ulcerative colitis in mice via suppressing TXNIP-dependent NF-κB pathway显示文摘Oroxindin is a flavonoid isolated from the traditional Chinese medicine Huang-Qin,which has shown various pharmacological activities including anti-inflammatory,antitumor,antioxidant,etc.Thus far,the effect of oroxindin on colonic inflammation and the underlying mechanism remain unknown.In this study,we investigated the tissue distribution of oroxindin and its therapeutic effects on ulcerative colitis(UC)as well as the underlying mechanisms.UC model was established in mice by administrating dextran sulfate sodium(DSS)in drinking water for 7 d.We first showed that oroxindin was largely absorbed by the colon as an active ingredient after normal mice received Huang-Qin-Tang,a traditional Chinese medicine decoction.UC mice were then treated with oroxindin(12.5,25,50 mg-kg^-1·d^-1,i.g.)for 10 d.We found that oroxindin treatment greatly suppressed massive macrophages infiltration and attenuated pathological changes in colonic tissue.Furthermore,oroxindin treatment significantly inhibited the generation of IL-13 and IL-18 in the colon via inhibiting the nucleotide-binding oligomerization domain-like receptor 3(NLRP3)inflammasome formation and activation.In cultured macrophages,LPS induced NLRp3 inflammasome formation and caspase-1 activation,which were suppressed by oroxindin(12.5-50μM).In LPS-treated macrophages,oroxindin dose-dependently restored the expression of TXNIP protein,leading to suppressing TXNIP-dependent NF-κB activation.In conclusion,these results demonstrate that oroxindin could be absorbed by the colon and attenuate inflammatory responses via inhibiting NLRP3 inflammasome formation and activation,which is related to the inhibitory effect on TXNIP-dependent NF-κB-signaling pathway.Hence,oroxindin has the potential of becoming an effective drug for treating UC. | Qi Liu Rui Zuo Kai Wang Fei-fei Nong Ya-jun Fu Shao-wei Huang Zeng-feng Pan Yi Zhang Xia Luo Xiang-liang Deng Xiao-xue Zhang Lian Zhou Yang Chen | 2020 | Acta Pharmacologica Sinica2020，41，6： | 15 |
| 5 | Temporal echocardiography findings in patients with fulminant myocarditis: beyond ejection fraction decline显示文摘The features of myocardial strains from speckle-tracking echocardiography (STE) have not been well defined in fulminant myocarditis (FM) patients.In this study,changes in the left ventricular ejection fraction (LVEF) and global and layer-specific myocardial strains over time were monitored.We aimed to determine the echocardiographic patterns of FM and ascertain their significance in FM treatment.Twenty patients who were clinically diagnosed with FM and received mechanical life support were prospectively enrolled.Conventional echocardiographic measurements were obtained,and serial strain echocardiography was performed from admission to hospital discharge until LVEF recovery (> 50%).Global/regional peak systolic longitudinal strains (GLS/RLS) and layer-specific longitudinal strains were quantified,and their changes with time were monitored in 14 FM patients.All patients had severely impaired cardiac function.Steep improvement in LVEF and GLS were observed within 6 days.Layer-specific strain analysis showed that reduction at admission or recovery at discharge in the endocardium and epicardium strains were equal.In conclusion,FM patients who received mechanical circulatory supports exhibited steep improvement in ventricular function within 6 days.The patchy and diffused distribution pattern of reduced RLS and equally and severely impaired strain in the endocardium and epicardium are valuable features in the diagnosis of FM. | Houjuan Zuo Rui Li Fei Ma Jiangang Jiang Kun Miao Haojie Li Eike Nagel Marijana Tadic Hong Wang Dao Wen Wang | 2020 | Frontiers of Medicine2020，14，3： | 10 |
| 6 | Aqueous-phase catalytic hydrogenation of furfural to cyclopentanol over Cu-Mg-Al hydrotalcites derived catalysts:Model reaction for upgrading of bio-oil显示文摘A series of Cu-Mg-Al hydrotalcites derived oxides with a(Cu+Mg)/Al mole ratio of 3 and varied Cu/Mg mole ratio(from 0.07 to 0.30) were prepared by co-precipitation and calcination methods, then they were introduced to the hydrogenation of furfural in aqueous-phase. Effects of Cu/Mg mole ratio, reaction temperature, initial hydrogen pressure, reaction time and catalyst amount on the conversion rate of furfural as well as the selectivity toward desired product cyclopentanol were systematically investigated. The conversion of furfural over calcined hydrotalcite catalyst with a Cu/Mg mole ratio of 0.2 was up to 98.5% when the reaction was carried out under 140 ?C and the initial hydrogen pressure of 4 MPa for 10 h, while the selectivity toward cyclopentanol was up to 94.8%. The catalysts were characterized by XRD and SEM. XRD diffraction of all the samples showed characteristic pattern of hydrotalcite with varied peak intensity as a result of different Cu content. The catalytic activity was improved gradually with the increase of Cu component in the hydrotalcite. | Minghao Zhou Zuo Zeng Hongyan Zhu Guomin Xiao Rui Xiao | 2014 | Journal of Energy Chemistry2014，23，1： | 9 |
| 7 | Safety and efficacy of stent-assisted coiling for acutely ruptured wide-necked intracranial aneurysms:comparison of LVIS stents with laser-cut stents显示文摘Background:To compare the safety and efficacy of LVIS stent-assisted coiling with those of laser-cut stent-assisted coiling for the treatment of acutely ruptured wide-necked intracranial aneurysms.Methods:Patients with acutely ruptured wide-necked intracranial aneurysms treated with LVIS stent-assisted coiling(LVIS stent group)and laser-cut stent-assisted coiling(laser-cut stent group)were retrospectively reviewed from January 2014 to December 2017.Propensity score matching was used to adjust for potential differences in age,sex,aneurysm location,aneurysm size,neck width,Hunt-Hess grade,and modified Fisher grade.Perioperative procedure-related complications and clinical and angiographic follow-up outcomes were compared.Univariate and multivariate analyses were performed to determine the associations between procedure-related complications and potential risk factors.Results:A total of 142 patients who underwent LVIS stent-assisted coiling and 93 patients who underwent laser-cut stent-assisted coiling were enrolled after 1:2 propensity score matching.The angiographic follow-up outcomes showed that the LVIS stent group had a slightly higher complete occlusion rate and lower recurrence rate than the laser-cut stent group(92.7%vs 80.6%;3.7%vs 9.7%,P=0.078).The clinical outcomes at discharge and follow-up between the two groups demonstrated no significant differences(P=0.495 and P=0.875,respectively).The rates of intraprocedural thrombosis,postprocedural thrombosis,postoperative early rebleeding,and procedure-related death were 0.7%(1/142),1.4%(2/142),2.8%(4/142),and 2.1%(3/142)in the LVIS stent group,respectively,and 4.3%(4/93),2.2%(2/93),1.1%(1/93),and 3.2%(3/93)in the laser-cut stent group,respectively(P=0.082,0.649,0.651,and 0.683).Nevertheless,the rates of overall procedure-related complications and intraprocedural rupture in the LVIS stent group were significantly lower than those in the laser-cut stent group(5.6%vs 14.0%,P=0.028;0.7%vs 6.5%,P=0.016).Multivariate analysis showed that laser-cut stent-assisted coiling was an independent predictor for overall procedurerelated complications(OR=2.727,P=0.037);a history of diabetes(OR=7.275,P=0.027)and other cerebrovascular diseases(OR=8.083,P=0.022)were independent predictors for ischemic complications,whereas none of the factors were predictors for hemorrhagic complications.Conclusions:Compared with laser-cut stent-assisted coiling,LVIS stent-assisted coiling for the treatment of acutely ruptured wide-necked intracranial aneurysms could reduce the rates of overall procedure-related complications and intraprocedural rupture. | Gaici Xue Qiao Zuo Xiaoxi Zhang Haishuang Tang Rui Zhao Qiang Li Yibin Fang Pengfei Yang Bo Hong Yi Xu Qinghai Huang Jianmin Liu | 2021 | Chinese Neurosurgical Journal2021，7，2： | 8 |
| 8 | Induction of cytotoxic T lymphocyte respones in vivo after immunotherapy with dendritic cells in patients with nasopharyngeal carcinoma显示文摘The aim of the present study was to determine the efficacy of immunotherapy with dendritic cells to elicit EBV-specific CTL-immunity in advanced cases of EBV-positive patients with nasopharyngeal carcinoma (NPC) and to determine the safety and toxicity of this preparation. Nine cases of histologically confirmed patients with NPC undergoing treatment with radiological therapy were enrolled in this study. Dendritic cells, generated in vitro from blood monocytes of patients were cultured and matured with cytokines and then infected with recombinant adenovirus vaccine containing EBV-latent membrane protein-2 (Ad-LMP2). On 9 days' cultivation of cells, the matured DCs were harvested, irradiated with Co and then injected intradermally to patients with NPC. The injections were performed 3 times totally. After immunization, the CTL responses were assayed by means of cytotoxicity and epitope-specific IFN-γproduction. The results of this trial showed that all patients could tolerate this kind of treatment without any side effect, during which marked increase of LMP2-specific CTL-responses could be demonstrated in 5 patients of this group. And the level of IgA/VCA antibody decreased in 8 of 9 patients, thus accounting for a better prognosis for these patients. All patients will be followed up for another one year. At least, the present work shows that intradermal vaccination with autologous DCs infected with recombinant Ad-LMP2 adenovirus is a safe procedure in NPC patients, in which this procedure can enhance the LMP2-specific CTL responses in patients. These data are encouraging to develop more effective vaccine strategies for the treatment of nasopharyngeal carcinoma. | JIAN MIN ZUO LING ZHOU ZHI JIAN CHEN DE RUI LI QI WANG JIONG YU CHEN ZHAN WANG SI-IU QING WE YI ZENG | 2006 | Journal of Microbiology and Immunology2006，4，1： | 7 |
| 9 | Prehistoric agriculture development in the Yunnan-Guizhou Plateau, southwest China: Archaeobotanical evidence显示文摘The origin, development and expansion of prehistoric agriculture in East Asia have been widely investigated over the past two decades using archaeobotanical analysis from excavated Neolithic and Bronze Age sites. Research on prehistoric agriculture has predominantly focused in the valleys of the Yellow River and the Yangtze River. Agricultural development during the Neolithic and Bronze Age periods in the Yunnan-Guizhou Plateau of southwest China, an important passageway for human migration into Southeast Asia, still remains unclear. In this paper, based on macrofossil and microfossil analysis and radiocarbon dating at the Shilinggang site, we investigate plant subsistence strategies in the Nujiang River valley during the Bronze Age period. Combined with previous archaeobotanical studies in the Yunnan-Guizhou Plateau, we explore agricultural development processes in this area during the Neolithic and Bronze Age. Our results indicate that rice and foxtail millet were cultivated in Shilinggang around 2500 cal a BP. Three phases of prehistoric agricultural development in the Yunnan-Guizhou Plateau can be identified: rice cultivation from 4800–3900 cal a BP, mixed rice and millet crop(foxtail millet and broomcorn millet) cultivation from 3900–3400 cal a BP, and mixed rice, millet crop and wheat cultivation from 3400–2300 cal a BP. The development of agriculture in the Yunnan-Guizhou Plateau during the Neolithic and Bronze Age periods was primarily promoted by prehistoric agriculture expansion across Eurasia, agricultural expansion which was also affected by the topographic and hydrological characteristics of the area. | LI HaiMing ZUO XinXin KANG LiHong REN LeLe LIU FengWen LIU HongGao ZHANG NaiMeng MIN Rui LIU Xu DONG GuangHui | 2016 | Science China Earth Sciences2016，59，8： | 6 |
| 10 | Propofol vs midazolam plus fentanyl for upper gastrointestinal endomicroscopy:A randomized trial显示文摘AIM:To compare the endomicroscopic image quality of integrated confocal laser endomicroscopy(iCLE)and sedation efficacy of propofolvs midazolam plus fentanyl(M/F).METHODS:Consecutive outpatients undergoing iCLE were prospectively recruited and randomized to the propofol group(P group)or M/F group.The patient,performing endoscopist and endoscopic assistant were blinded to the randomization.The quality of endomicro-scopic images and anesthetic efficacy outcomes were blindly evaluated after iCLE examination.RESULTS:There were significantly more good quality endomicroscopic images in the propofol group than in the M/F group(72.75%vs 52.89%,P<0.001).The diagnostic accuracy for upper gastrointestinal mucosal lesions using confocal laser endomicroscopy favors the P group,although this did not reach statistical significance.Adverse events and patient assessment were not significantly different for M/F vs propofol except for more frequent intraprocedural recall with M/F.Procedure duration and sedation times were significantly longer in the M/F group,while the scores of endoscopist,anesthetist and assistant assessment were all significantly better in the P group.CONCLUSION:Sedation with propofol might increase the proportion of good quality endomicroscopic images,and may result in improved procedural efficacy and diagnostic accuracy during iCLE examination. | Xiu-Li Zuo Zhen Li Xiao-Ping Liu Chang-Qing Li Rui Ji Peng Wang Cheng-Jun Zhou Han Liu Yan-Qing Li | 2012 | World Journal of Gastroenterology2012，18，15： | 6 |

| 12 | Magnified and enhanced computed virtual chromoendoscopy in gastric neoplasia: A feasibility study显示文摘AIM: To evaluate the feasibility of a new computed virtual chromoendoscopy (CVC) device (M i-scan) in the diagnosis of gastric neoplasia. METHODS: Patients with superficial lesions no larger than 1.0 cm found during high definition endoscopy were included. Those with advanced or obviously protruded or depressed lesions, lesions larger than 1.0 cm and/or lesions which were not amenable to observation by zoom function were excluded. The endoscopist was required to give the real-time descriptions of surface pit patterns of the lesions, based on surface pattern classification of enhanced magnification endoscopy. According to previous reports, types Ⅰ-Ⅲ represent nonneoplastic lesions, and types Ⅳ-Ⅴ represent neoplastic lesions. Diagnosis with M i-scan and biopsy was performed before histopathological diagnosis. Magnified images of gastric lesions with and without enhancement were collected for further analysis. The diagnostic yield of real-time M i-scan and effects on magnification image quality by tone enhancement (TE), surface enhancement (SE) and color enhancement (CE) were calculated. The selected images were sent to another endoscopist. The endoscopist rated the image quality of each lesion at 3 levels. Ratings of image quality were based on visualization of pit pattern, vessel and demarcation line. RESULTS: One hundred and eighty-three patients were recruited. Five patients were excluded for advanced gastric lesions, 1 patient was excluded for poor preparation and 2 patients were excluded for superficial lesions larger than 1.0 cm; 132 patients were excluded for no lesions found by high definition endoscopy. In the end, 43 patients with 43 lesions were included. Histopathology revealed 10 inflammation, 14 atrophy, 10 metaplasia, 1 low grade dysplasia (LGD), 5 high grade dysplasia (HGD) and 3 cancers. For 7 lesions classified into type Ⅰ, histopathology revealed 6 atrophy and 1 metaplasia; for 10 lesions classified into type Ⅱ, histopathology revealed 2 inflammation, 7 atrophy and 1 metaplasia; for 10 lesions classified into type Ⅲ, histopathology revealed 1 inflammation, 8 metaplasia and 1 LGD; for 9 lesions classified into type Ⅳ, histopathology revealed 4 inflammation, 1 atrophy and 4 HGD; for 7 lesions classified into type Ⅴ, histopathology revealed 3 inflammation, 1 HGD and 3 cancers. A total of 172 still images, including 43 images by white light (MWL) and 129 images by M i-scan (43 with TE, 43 with SE and 43 with CE), were selected and sent to the endoscopist who did the analysis. General image quality of M i-scan with TE and SE was significantly better than that of MWL (TE, 4.55 ± 1.07; SE, 4.30 ± 1.02; MWL, 3.25 ± 0.99; P < 0.001). Visualization of pit pattern was significantly improved by M i-scan with SE (1.93 ± 0.25 vs 1.50 ± 0.50, P < 0.001). Microvessel visualization was significantly improved by M i-scan with TE (1.23 ± 0.78 vs 0.76 ± 0.73, P < 0.001). Demarcation line visualization was improved by M i-scan with both TE and SE (TE, 1.75 ± 0.52; SE, 1.56 ± 0.59; MWL, 0.98 ± 0.44; P < 0.001). M i-scan with CE did not show any significant improvements of image quality in general or in the 3 key parameters. Although M i-scan with TE and SE slightly increased the diagnostic yield of MWL, there was no significant difference (P > 0.1). CONCLUSION: Although digital enhancement improves the image quality of magnification endoscopy, its value in improving the diagnostic yield seems to be limited. | Chang-Qing Li Ya Li Xiu-Li Zuo Rui Ji Zhen Li Xiao-Meng Gu Tao Yu Qing-Qing Qi Cheng-Jun Zhou Yan-Qing Li | 2013 | World Journal of Gastroenterology2013，19，26： | 5 |
| 13 | Crystal orientation and morphology of a lamellae in wrought titanium alloys: On the role of microstructure evolution in b processing显示文摘To obtain high-quality aviation forgings of titanium alloys, b forging is an essential processing step which must be considered throughout a production process. In this work, the effect of b forging on the crystal orientation and morphology of lamellar a was experimentally investigated in a two-phase titanium alloy. Strong dynamic recovery during b working resulted in the formation of low-angle grain boundary(LAGBb) inside b grains. The lamellar a can penetrate through the LAGBb, leading to similar intra a LAGBs on subgrain boundaries. Deformation banding occurs at high strain rates, and both diffusive and sharp boundaries of deformation bands can be observed.A continuous change of the b orientation in diffusive boundaries results in the formation of fine and disordered a lamellae without intra-lamellar boundary to hold the Burgers orientation relationship(OR). On sharp boundaries, it is prone to producing continuous grain boundary a(aGB) with a highly similar orientation along the boundaries. Meanwhile, there may exist several lower-angle boundaries within the grain boundary a for a smoother orientation change on the b grain boundary. | Huojun ZHENG Xiaoguang FAN Xiang ZENG Rui ZUO | 2019 | Chinese Journal of Aeronautics2019，32，5： | 5 |
| 14 | Evolution and Domestication Footprints Uncovered from the Genomes of Coix显示文摘Coix lacryma-jobi,a plant species closely related to Zea and Sorghum,is an important food and medicinal crop in Asia.However,no reference genome of this species has been reported,and its exact phylogeny within the Andropogoneae remains unresolved.Here,we generated a high-quality genome assembly of coix comprising~1.73 Gb with 44485 predicted protein-coding genes.We found coix to be a typical diploid plant with an overall 1-to-1 syntenic relationship with the Sorghum genome,despite its drastic genome expansion(~2.3-fold)due mainly to the activity of transposable elements.Phylogenetic analysis revealed that coix diverged with sorghum~10.41 million years ago,which was~1.49 million years later than the divergence between sorghum and maize.Resequencing of 27 additional coix accessions revealed that they could be unambiguously separated into wild relatives and cultivars,and suggested that coix experienced a strong genetic bottleneck,resulting in the loss of about half of the genetic diversity during domestication,even though many traits have remained undomesticated.Our data not only provide novel comparative genomic and evolutionary insights into the Andropogoneae lineage,but also an important resource that will greatly benefit molecular breeding of this important crop. | Hongbing Liu Junpeng Shi Zexi Cai Yumin Huang Menglu Lv Huilong Du Qiang Gao Yi Zuo Zhaobin Dong Wei Huang Rui Qin Chengzhi Liang Jinsheng Lai Weiwei Jin | 2020 | Molecular Plant2020，13，2： | 4 |
| 15 | Simulation analysis on characteristics of land surface over western Qinghai-Xizang Plateau during freez-ing-thawing period显示文摘Using the Global Energy and Water Cycle Experiment-Asian Monsoon-Tibet Plateau Experiment (GAME-Tibet) observa-tional data-from October 2002 through September 2003-of Gaize in the western Qinghai-Xizang Plateau (QXP),the land-surface characteristics of the Qinghai-Xizang Plateau are simulated by the improved land-surface model Common Land Model (CoLM).The results show that CoLM can reproduce the land-surface characteristics of plateau areas well.In the sur-face-energy balance of the western QXP in the winter half year,the sensible heat (SH) flux constituted the dominant energy,and the latent heat (LH,here and after) flux is very small.Although the LH flux nearly equals zero in freezing season,it cannot be ig-nored during the period of freezing-thawing in QXP.In the transition season from midto late-May,the frequent phase change of soil water that is caused by the freezing-thawing process leads to the increase of LH flux and decrease of the Bowen ratio.The simulation results also indicate that the changes of surface effective heat fluxes (SH and LH flux) are associated with precipitation and the frequent change between freezing and thawing processes in soil surface. | ChengHai Wang,Rui Shi,Yang Cui,HongChao Zuo College of Atmospheric Sciences,Lanzhou University.No.222,South Tianshui Road,Lanzhou,Gansu 730000,China. | 2009 | Research in Cold and Arid Regions2009，1，4： | 3 |

| 17 | Data processing and preliminary results of the Chang'e-3 VIS/NIR Imaging Spectrometer in-situ analysis显示文摘The Chang'e-3 Visible and Near-infrared Imaging Spectrometer(VNIS) is one of the four payloads on the Yutu rover. After traversing the landing site during the first two lunar days, four different areas are detected, and Level 2A and 2B radiance data have been released to the scientific community. The released data have been processed by dark current subtraction, correction for the effect of temperature,radiometric calibration and geometric calibration. We emphasize approaches for reflectance analysis and mineral identification for in-situ analysis with VNIS. Then the preliminary spectral and mineralogical results from the landing site are derived. After comparing spectral data from VNIS with data collected by the M3 instrument and samples of mare that were returned from the Apollo program, all the reflectance data have been found to have similar absorption features near 1000 nm except lunar sample71061. In addition, there is also a weak absorption feature between 1750~2400 nm on VNIS, but the slopes of VNIS and M3 reflectance at longer wavelengths are lower than data taken from samples of lunar mare. Spectral parameters such as Band Centers and Integrated Band Depth Ratios are used to analyze mineralogical features. The results show that detection points E and N205 are mixtures of high-Ca pyroxene and olivine,and the composition of olivineat point N205 is higher than that at point E, but the compositions of detection points S3 and N203 are mainly olivine-rich.

| 18 | Geochronology and geochemistry of Late Carboniferous dykes in the Aqishan-Yamansu belt,eastern Tianshan:Evidence for a post-collisional slab breakoff显示文摘With aim of providing constraints on the Late Paleozoic tectonic evolution of the southern Central Asian Orogenic Belt(CAOB),an integrated study was conducted on the geochronological and geochemical data for dioritic,granitic and diabase dykes from the Aqishan-Yamansu belt in the eastern Tianshan,NW China.Zircon U-Pb dating indicates that the dioritic and granitic dykes were both emplaced in the Late Carboniferous(~311 Ma and^315 Ma).The dioritic dykes show adakitic characteristics and have high Na2 O and positiveεHf(t)values(+12 to+17),which suggest an origin from partial melts of a subducted oceanic slab.The granitic dykes have high SiO2 and K2 O contents and are characterized by en riched light rare earth elements(LREE)and slightly flat heavy rare earth elements(HREE),with negative Eu and Nb-Ta-Ti anomalies.These dykes are alkali-calcic and show geochemical features of highly fractionated Itype granites.Their positiveεHf(t)values(+16 to+17)suggest that they were derived from a juvenile accreted oceanic crustal sou rce.The coeval diabase dykes have low SiO2 and K2 O contents but high TiO2,MgO and Mg#(54-59).They are enriched in LREE and show characteristics of enriched mid-ocean ridge basalts(E-MORB).The relatively high Ba/Th,slightly low Th/Ta ratios,and negative Nb-Ta anomalies imply a mantle source metasomatised by slab-derived fluids.Thus,these basic dykes were generated likely by partial melting of the upwelling asthenosphere mantle with a slight influence of slab-derived fluids.Therefore,we suggest that the formation of these Late Carboniferous dykes were triggered by a post-collisional slab breakoff and the Aqishan-Yamansu belt was a continental arc formed by southdipping subduction of the Kangguer oceanic plate. | Xiaoping Long Bin Wu Min Sun Chao Yuan Wenjiao Xiao Rui Zuo | 2020 | Geoscience Frontiers2020，11，1： | 3 |
