| 1 | High-Resolution Records of the Holocene Paleoenvironmental Variation Reflected by Carbonate and Its Isotopic Compositions in Bosten Lake and Response to Glacial Activities显示文摘The Early Holocene paleoclimate in Bosten Lake on the northern margin of the Tarim Basin, southern Xinjiang, is reconstructed through an analysis of a 953 cm long core (BSTC2000) taken from Bosten Lake. Multiple proxies of this core, including the mineral components of carbonate, carbonate content, stable isotopic compositions of carbonate, Ca/Sr, TOC and C/N and C/S of organic matter, are used to reconstruct the climatic change since 8500 a B.P. The chronology model is made by nine AMS 14C ages of leaves, seeds and organic matter contained in two parallel cores. The climate was cold and wet during 8500 to 8100 a B.P. Temperature increased from 8100 to 6400 a B.P., the climate was warm and humid, and the lake expanded. The lake level was highest during this stage. Then from 6400 to 5100 a B.P., the climate became cold and the lake level decreased slightly. During the late mid-Holocene, the climate was hot and dry from 5100 to 3100 a B.P., but there was a short cold period during 4400 to 3800 a B.P. At this temporal interval, a mass of ice and snow melting water supplied the lake at the early time and made the lake level rise. The second highest lake level stage occurred during 5200 to 3800 a B.P. The climate was cool and wet during 3100 to 2200 a B.P., when the lake expanded with decreasing evaporation. The lake had the last short-term high level during 3100 to 2800 a B.P. After this short high lake level period, the lake shrank because of the long-term lower temperature and reduced water supply. From 2200 to 1200 a B.P., the climate was hot and dry, and the lake shrank greatly. Although the temperature decreased somewhat from 1200 a B.P. to the present, the climate was warm and dry. The lake level began to rise a little again, but it did not reach the river bed altitude of the Konqi River, an outflow river of the Bosten Lake. | ZHANG Chengjun ZHENG Mianping Alexander PROKOPENKO Steffen MISCHKE GOU Xiaohui YANG Qili ZHANG Wanyi FENG Zhaodong | 2009 | Acta Geologica Sinica(English Edition)2009，83，6： | 10 |
| 2 | Determination of trophic relationships within a Bohai Bay food web using stable δ^(15)N and δ^(13)C analysis显示文摘This study measured stable carbon and nitro- gen isotope ratios in phytoplankton, zooplankton, five inver- tebrates species, eight fishes species and three seabirds spe- cies collected in Bohai Bay. δ 13C ranged from ?25.38‰ to ?11.08‰ showing a relative low enrichment in the food web from Bohai Bay. The mean δ 13C of mullet is higher than that of other organisms, and this might be due to that mullet is migration fish and feeds mainly on inshore sources. δ 15N ranged from 4.08‰ to 13.98‰, and showed a step-wise en- richment with trophic level of 3.8‰. The δ 15N enrichment factor was used to construct an isotopic food web model to establish trophic relationships within this marine food web. According to this model, exact trophic levels of all organisms were estimated as 1.46?2.10, 1.91?3.32, 2.55?4.23 and 2.98?4.28 for plankton, invertebrates, fishes, and seabirds. | WANYi HUJianying ANLihui ANWei YANGMin ItohMitsuaki HattoriTatsuya1 TAOShu | 2005 | Chinese Science Bulletin2005，50，10： | 10 |
| 3 | Paleozoic Intrusive Rocks in the Nalati Mountain Range(NMR), Southwest Tianshan: Geodynamic Evolution Based on Petrology and Geochemical Studies显示文摘A synthesis involving the data for the Nalati mountain region(NMR) in west Tianshan with a dataset including zircon U-Pb ages, Hf isotopic composition, major and trace elements of Paleozoic intrusions are presented to improve the understanding of regional geodynamic evolution. Paleozoic intrusive rocks in the NMR could be classified into four categories based on chronological and geochemical data: 480?5 Ma, 445–410 Ma, 345–320 Ma, and 295 Ma, which correspond to(1) closure of the Terskey Ocean and the opening of the south Tianshan back-arc basin, which was followed with the opening of the south Tianshan Ocean,(2) initial subduction of the south Tianshan oceanic crust,(3) major subduction stage, and(4) collision to post-collisional stage, respectively. Following the closure of the Terskey Ocean, the south Tianshan Ocean opened at Early Silurian and subducted under Yili-central Tianshan by the end of Early Carboniferous Period. The following breakoff of the subducted slab triggered partial melting of continental crust and formed voluminous granitic rocks in the NMR. | Huichao Zhang Yongfeng Zhu Wanyi Feng Yuwen Tan Fang An Jiahao Zheng | 2017 | Journal of Earth Science2017，28，2： | 9 |

| 7 | Methodology for credibility assessment of historical global LUCC datasets显示文摘Land use-induced land cover change(LUCC)is an important anthropogenic driving force of global change that has influenced,and is still influencing,many aspects of regional and global environments.Accurate historical global land use/cover datasets are essential for a better understanding of the impacts of LUCC on global change.However,there are not only evident inconsistencies in current historical global land use/cover datasets,but inaccuracies in the data in these global dataset revealed by historical record-based reconstructed regional data throughout the world.A focus in historical LUCC and global change research relates to how the accuracy of historical global land cover datasets can be improved.A methodology for assessing the credibility of existing historical global land cover datasets that addresses temporal as well as spatial changes in the amount and distribution of land cover is therefore needed.Theoretically,the credibility of a global land cover dataset could be assessed by comparing similarities or differences in the data according to actual land cover data(the'true value').However,it is extremely difficult to obtain historical evidence for assessing the credibility of historical global land cover datasets,which cannot be verified through field sampling like contemporary global land cover datasets.We proposed a methodological framework for assessing the credibility of global land cover datasets.Considering the types and characteristics of the available evidence used for assessments,we outlined four methodological approaches:(1)accuracy assessment based on regional quantitative reconstructed land cover data,(2)rationality assessment based on regional historical facts,(3)rationality assessment based on expertise,and(4)likelihood assessment based on the consistency of multiple datasets.These methods were illustrated through five case studies of credibility assessments of historical cropland cover data.This framework can also be applied in assessments of other land cover types,such as forest and grassland. | Xiuqi FANG Wanyi ZHAO Chengpeng ZHANG Diyang ZHANG Xueqiong WEI Weili QIU Yu YE | 2020 | Science China Earth Sciences2020，63，7： | 4 |
| 8 | Glucose and MMP-9 dual-responsive hydrogel with temperature sensitive self-adaptive shape and controlled drug release accelerates diabetic wound healing显示文摘Chronic diabetic wounds are an important healthcare challenge. High concentration glucose, high level of matrix metalloproteinase-9 (MMP-9), and long-term inflammation constitute the special wound environment of diabetic wounds. Tissue necrosis aggravates the formation of irregular wounds. All the above factors hinder the healing of chronic diabetic wounds. To solve these issues, a glucose and MMP-9 dual-response temperature-sensitive shape self-adaptive hydrogel (CBP/GMs@Cel&INS) was designed and constructed with polyvinyl alcohol (PVA) and chitosan grafted with phenylboric acid (CS-BA) by encapsulating insulin (INS) and gelatin microspheres con-taining celecoxib (GMs@Cel). Temperature-sensitive self-adaptive CBP/GMs@Cel&INS provides a new way to balance the fluid-like mobility (self-adapt to deep wounds quickly, approximately 37 ◦C) and solid-like elasticity (protect wounds against external forces, approximately 25 ◦C) of self-adaptive hydrogels, while simultaneously releasing insulin and celecoxib on-demand in the environment of high-level glucose and MMP-9. Moreover, CBP/ GMs@Cel&INS exhibits remodeling and self-healing properties, enhanced adhesion strength (39.65 ± 6.58 kPa), down-regulates MMP-9, and promotes cell proliferation, migration, and glucose consumption. In diabetic full-thickness skin defect models, CBP/GMs@Cel&INS significantly alleviates inflammation and regulates the local high-level glucose and MMP-9 in the wounds, and promotes wound healing effectively through the synergistic effect of temperature-sensitive shape-adaptive character and the dual-responsive system. | Wanyi Zhou Zhiguang Duan Jing Zhao Rongzhan Fu Chenhui Zhu Daidi Fan | 2022 | Bioactive Materials2022，7，11： | 4 |

| 10 | Geochemistry and Zircon U–Pb–Hf Isotopic Systematics of the Sanchahe Quartz Monzonite Intrusion in the North Qinling Tectonic Zone, Central China: Implications for its Petrogenesis and Tectonic Setting显示文摘The Sanchahe quartz monzonite intrusion is situated in the middle segment of the North Qinling tectonic belt, Central China mainland, and consists chiefly of sanukitoid–like and granodioritic-monzogranitic rocks. The sanukitoid–like rocks are characterized by quartz monzonites, which display higher Mg#(55.0–59.0), and enrichments in Na2 O+K2 O(7.28–8.94 %), Ni(21-2312 ppm), Cr(56-4167 ppm), Sr(553-923 ppm), Ba(912-1355 ppm) and LREE((La/Yb)N =9.47–15.3), from negative to slightly positive Eu anomalies(δEu=+0.61 to +1.10), but also depletion in Nb, Ta and Ti. The granodioritic-monzogranitic rocks diaplay various Mg#of 6.00-53.0, high Na2 O+K2 O(7.20– 8.30%), Sr(455–1081 ppm) and(La/Yb)N(27.6–47.8), with positive Eu anomalies(δEu=1.03–1.57) and depleted Nb, Ta and Ti. Laser ablation inductively coupled plasma mass spectrometry(LA-ICPMS) zircon U-Pb isotopic dating reveals that the sanukitoid-like rocks were emplaced at two episodes of magmatism at 457±3 Ma and 431±2 Ma, respectively. The monzogranites were emplaced at 445±7Ma. Sanukitoid–like rocks have their εHf(t) values ranging from +0.3 to +15.1 with Hf–depleted mantle model ages of 445 to 1056 Ma, and the monzogranite shows its εHf(t) values ranging from 21.6 to +10.8 with Hf–depleted mantle model ages of 635 to 3183 Ma. Petrological, geochemical and zircon Lu –Hf isotopic features indicate that the magmatic precursor of sanukitoid–like rocks was derived from partial melting of the depleted mantle wedge materials that were metasomatized by fluids and melts related to subduction of oceanic slab, subsequently the sanukitoid magma ascended to crust level. This emplaced mantle magma caused partial melting of crustally metamorphosed sedimentary rocks, and mixing with the crustal magma, and suffered fractional crystallization, which lead to formations of quartz monzonites. However, the magmatic precursor of the granodioritic-monzogranitic rocks were derived from partial melting of subducted oceanic slab basalts. Integrated previous investigation for the adackitic rocks in the south of the intrusion, the Sanchahe intrusion signed that the North Qinling tectonic zone was developed in an early Paleozoic transitionally tectonic background from an island arc to back–arc. | YAN Ming LIU Shuwen LI Qiugen ZHANG Wanyi YANG Pengtao YAN Zhen WANG Ruiting WANG Wei GUO Rongrong | 2014 | Acta Geologica Sinica(English Edition)2014，88，1： | 3 |
| 11 | Isolation and diversity analysis of heterotrophic bacteria associated with sea anemones显示文摘A study was undertaken to investigate the heterotrophic bacterial flora associated with the sea anemones.Samples of the sea anemones Anthopleura midori were collected from the coast of Weihai and bacteria were isolated from these samples.Additionally,high numbers of viable bacteria were obtained from the celom wall and surface of anemone,the community of cultivable bacteria was very diverse.As a result of this isolation,60 strains were obtained,56 of them were selected for identification and characterization by 16S rRNA gene sequence analysis and limited phenotypic testing.Among these isolates,16 strains were phylogenetically related to members of the genus P seudoalteromonas and neighboring taxa.Other isolates included members of the genera Colwellia,Vibrio,Acinetobacter,Pseudomonas,Endozoicomonas,Roseovarius,Paracoccus,Loktanella,Leisingera,Sulfitobacter,Bacillus,Staphylococcus,Plantibacter,Microbacterium,Micrococcus,Joostella,Psychroserpens,Cellulophaga,Krokinobacter,Polaribacter and P sychrobacter.Seven potential novel species were found.Among 60 strains,17 of them can produce proteolytic exoenzyme,20 can produce lipolytic exoenzyme.Strain NQ8 has strong antagonistic effects on some Vibrio strains.This study demonstrates that the culturable fraction of bacteria from the sea anemones Anthopleura midori is diverse and appears to possess much potential as a source for the discovery of novel bioactive materials. | DU Zongjun ZHANG Wanyi XIA Hongjie LU Guoqiang CHEN Guanjun | 2010 | Acta Oceanologica Sinica2010，29，2： | 3 |
| 12 | Structural properties and catalytic performance of the La-Cu-Zn mixed oxides for CO2 hydrogenation to methanol显示文摘A series of La-Cu-Zn-O mixed oxide catalysts were synthesized by a co-precipitation method and calcined under different temperatures. The XRD, BET, TPR, N_2 O-adsorption, XPS, SEM and TPD techniques were carried out to measure the aimed catalysts. The results indicated that the chemical environment of lanthanum element changes with the increase of calcination temperature. The La_2 CuO_4 perovskite structure is obtained at the temperature higher than 823 K and the special copper species appear in the perovskites due to the special structure property. The catalysts with La_2 CuO_4 perovskite structure show higher methanol selectivity compared with the mixed copper catalyst. For the perovskite catalysts, the conversion of CO_2 changes with the same tendency of the copper species ratio((Cu^(α+)+Cu^0)/(Cu_(Total))%), which implied both Cu^(α+) and Cu^0 are important active sites in the perovskite catalyst for the reaction. | Haijuan Zhan Zhiqiang Wu Ning Zhao Wanyi Liu Wei Wei | 2018 | Journal of Rare Earths2018，36，3： | 3 |

| 14 | A 10-miRNA risk score-based prediction model for pathological complete response to neoadjuvant chemotherapy in hormone receptor-positive breast cancer显示文摘Patients with hormone receptor(HR)-positive tumors breast cancer usually experience a relatively low pathological complete response(p CR)to neoadjuvant chemotherapy(NAC).Here,we derived a 10-micro RNA risk score(10-mi RNA RS)-based model with better performance in the prediction of p CR and validated its relation with the disease-free survival(DFS)in 755 HRpositive breast cancer patients(273,265,and 217 in the training,internal,and external validation sets,respectively).This model,presented as a nomogram,included four parameters:the 10-mi RNA RS found in our previous study,progesterone receptor(PR),human epidermal growth factor receptor 2(HER2)status,and volume transfer constant(K).Favorable calibration and discrimination of 10-mi RNA RS-based model with areas under the curve(AUC)of 0.865,0.811,and 0.804 were shown in the training,internal,and external validation sets,respectively.Patients who have higher nomogram score(>92.2)with NAC treatment would have longer DFS(hazard ratio=0.57;95%CI:0.39–0.83;P=0.004).In summary,our data showed the 10-mi RNA RS-based model could precisely identify more patients who can attain p CR to NAC,which may help clinicians formulate the personalized initial treatment strategy and consequently achieves better clinical prognosis for patients with HRpositive breast cancer. | Chang Gong Ziliang Cheng Yaping Yang Jun Shen Yingying Zhu Li Ling Wanyi Lin Zhigang Yu Zhihua Li Weige Tan Chushan Zheng Wenbo Zheng Jiajie Zhong Xiang Zhang Yunjie Zeng Qiang Liu RStephanie Huang Andrzej LKomorowski Eddy SYang François Bertucci Francesco Ricci Armando Orlandi Gianluca Franceschini Kazuaki Takabe Suzanne Klimberg Naohiro Ishii Angela Toss Mona PTan Mathew A Cherian Erwei Song | 2022 | Science China(Life Sciences)2022，65，11： | 3 |
| 15 | Pattern Scan Laser Photocoagulator on Retinopathy: an annual clinical application summary显示文摘Purpose:To evaluate the clinical efficacy of Pattern Scan Laser Photocoagulator (PASCAL) by observing the efficacy of PASCAL on retinopathy.Methods:A total of 92 patients with retinopathy (121 eyes) who underwent PASCAL between December 2008 and February 2009 in our center were retrospectively analyzed to evaluate the visual acuity changes and recovery conditions of the patients from baseline to posterior to the treatment.The retinopathy included:diabetic retinopathy,ischemic retinal vein occlusion.(IRVO),central serous chorioretinopathy (CSC),retinal periphlebitis (Eales disease) and retinal degeneration /holes.Results:The patients were subject to a 12-month follow up after PASCAL.The visual acuity findings were stated as below:for diabetic retinopathy.(73 eyes),10 eyes had improved visual acuity;55 eyes were stabilized and 8 eyes progressed;for IRVO (13 eyes),4 eyes showed improvement,6 eyes were stabilized and 3 eyes progressed;for CSC (9 eyes),6 eyes were alleviated and 3 eyes progressed;for retinal periphlebitis (5 eyes),2 eyes had enhanced visual acuity and 3 eyes showed stable visual acuity;for retinal degeneration /holes (21 eyes),5 eyes presented improved visu-al acuity,16 eyes were stabilized and no eye progressed.Indirect ophthalmoscopic reexamination confirmed secured blockage by laser spots and favorable absorption of the retinal edema and newborn capillaries.No obvious leakage was observed during fundus fluorescein angiography and no laser-related ocular adverse effect was reported.Conclusion:PASCAL is accurate,effective and well-tolerated.The duration of short laser pulse falls within the safety range,ensuring the stabilization and improvement in the pa-tient's visual acuity.The parameters,long-term efficacy and complications of PASCAL should be further demonstrated by performing long-term clinical trials with larger sample size. | Haiyun Ye Chenjin Jin Xiaoqing Zhong Zhen Tian Wanyi Lin | 2011 | Eye Science2011，26，2： | 3 |
| 16 | Resource utilization of solid waste carbide slag:a brief review of application technologies in various scenes显示文摘China is the largest producer and consumer of calcium carbide in the world.The calcium carbide industry is an indispensable industry to support the basic life of people.The huge production capacity of calcium carbide is accompanied by a large number of solid waste carbide slag.Due to the immature treatment technology of carbide slag,a large number of carbide slag are stacked on-site,resulting in land occupation,air-drying,easy take-off ash,and pollution of the environment and water resources.In China,calcium carbide is mainly used to produce acetylene and further utilized,80%of which is used to produce polyvinyl chloride(PVC).A large amount of carbide slag is not used,while only a small part is used in the traditional building materials industry,flue gas desulfurization,sewage treatment,etc.,however,the economic benefits are poor.Therefore,converting the solid waste carbide slag produced by the calcium carbide industry into high value-added CaCO3,CaCl2,CaSO4 whiskers,etc.has become a potential way to expand the development field of the calcium carbide industry and is environmentally friendly.This paper focuses on summarizing the traditional and emerging high value-added utiliza-tion technologies of carbide slag,and then introduces the application research of carbide slag in carbon emission reduction.Finally,the defects of these technologies are summarized and further research directions are prospected.This study provides basic guidance for the diversified development of efficient resource utilization of carbide slag.Graphical abstract Diversified development of calcium carbide industry,resource utilization of solid waste carbide slag and its application of carbon emission reduction have been fully reviewed. | Hongxia Wang Wanyi Xu Maimoona Sharif Guangxu Cheng Zaoxiao Zhang | 2022 | Waste Disposal and Sustainable Energy2022，4，1： | 3 |
| 17 | Unexpected fast radical production emerges in cool seasons:implications for ozone pollution control显示文摘Ozone is a crucial air pollutant that damages human health and vegetation.As it is related to the photo-oxidation of the nitrogen oxides and volatile organic compounds,the summertime reduction of these precursors is the primary focus of current ozone mitigation strategies.During ozone pollution episodes in eastern China,an observed accumulation of daily total oxidants(O_(x)=NO_(2)+O_(3))in cool seasons(spring and autumn:60 ppb and winter 40 ppb)is comparable to that in summer(60 ppb),indicating fast photochemical production of secondary pollutants including ozone over the year.Unrecognized fast radical primary productions are found to counteract the increased termination of hydroxyl radical and unfavorable meteorological conditions to maintain the rapid total oxidant formations in cool seasons.Elucidating and regulating the primary radical sources may be critical for the secondary air pollution control in cool seasons. | Hongli Wang Yanhui Liu Xiaorui Chen Yaqin Gao Wanyi Qiu Shengao Jing Qian Wang Shengrong Lou Peter MEdwards Cheng Huang Keding Lu | 2022 | National Science Open2022，1，2： | 2 |

| 20 | Using self-location to calibrate the errors of observer positions for source localization显示文摘The uncertainty of observers' positions can lead to significantly degrading in source localization accuracy. This paper proposes a method of using self-location for calibrating the positions of observer stations in source localization to reduce the errors of the observer positions and improve the accuracy of the source localization. The relative distance measurements of the two coordinative observers are used for the linear minimum mean square error(LMMSE) estimator. The results of computer simulations prove the feasibility and effectiveness of the proposed method. With the general estimation errors of observers' positions,the MSE of the source localization with self-location calibration,which is significantly lower than that without self-location calibration, is approximating to the Cramer-Rao lower bound(CRLB). | Wanchun Li Wanyi Zhang Liping Li | 2014 | Journal of Systems Engineering and Electronics2014，25，2： | 2 |
