| 1 | Size,composition,and mixing state of individual aerosol particles in a South China coastal city显示文摘Aerosol samples were collected in summer in Macao,a coastal city of the Pearl River Delta Region in China.Morphology,size,elemental composition,and mixing state of individual aerosol particles were determined by scanning electron microscopy coupled energy dispersive X-ray(SEM/EDX) and transmission electron microscopy(TEM).Based on the morphologies of 5711 aerosol particles,they consist of soot(32%),mineral(17%),secondary(22%),and unknown fine particles(29%).The sizes of these particles were mostly distributed between 0.1 and 0.4 μm.Compositions of 202 mineral particles were obtained by SEM/EDX.Mineral particles were mainly classified into three types:Si-rich,Ca-rich,and Na-rich.The compositions of typical mineral particles can indicate their sources in sampling location.For example,mineral particles,collected along the main street,were associated with trace amounts of heavy metals,such as Zn,Ti,Mn,Ba,Pb,and As.TEM observations indicate that most Na-rich particles were aged sea salt particles(e.g.,Na2SO4 and NaNO3) which formed through heterogeneous chemical reactions between sea salt and acidic gases.Additionally,aging time of soot was short in Macao due to high humidity,high temperature,and high levels of sunlight in Macao.Most of soot and fine mineral dust particles were internally mixed with secondary particles. | Weijun Li Longyi Shao Zhishi Wang Rongrong Shen Shusheng Yang Uwa Tang | 2010 | Journal of Environmental Sciences2010，22，4： | 21 |
| 2 | Intestinal microbiota: a potential target for the treatment of postmenopausal osteoporosis显示文摘Postmenopausal osteoporosis(PMO) is a prevalent metabolic bone disease characterized by bone loss and structural destruction, which increases the risk of fracture in postmenopausal women. Owing to the high morbidity and serious complications of PMO, many efforts have been devoted to its prophylaxis and treatment. The intestinal microbiota is the complex community of microorganisms colonizing the gastrointestinal tract. Probiotics, which are dietary or medical supplements consisting of beneficial intestinal bacteria, work in concert with endogenous intestinal microorganisms to maintain host health. Recent studies have revealed that bone loss in PMO is closely related to host immunity, which is influenced by the intestinal microbiota. The curative effects of probiotics on metabolic bone diseases have also been demonstrated. The effects of the intestinal microbiota on bone metabolism suggest a promising target for PMO management.This review seeks to summarize the critical effects of the intestinal microbiota and probiotics on PMO, with a focus on the molecular mechanisms underlying the pathogenic relationship between bacteria and host, and to define the possible treatment options. | Xin Xu Xiaoyue Jia Longyi Mo Chengcheng Liu Liwei Zheng Quan Yuan Xuedong Zhou | 2017 | Bone Research2017，5，3： | 20 |
| 3 | Efficacy and safety of metformin and sitagliptin based triple antihyperglycemic therapy(STRATEGY):a multicenter,randomized,controlled,non-inferiority clinical trial显示文摘Despite the current guideline's recommendation of a timely stepwise intensification therapy,the 'clinical inertia',termed as the delayed treatment intensification,commonly exists in the real world,which may be partly due to the relatively little substantial evidence and no clear consensus regarding the efficacy and safety of triple oral agents in patients inadequately controlled with dual therapy.In this clinical trial performed in 237 centers in China,5,535 type 2 diabetic patients inadequately controlled by previous therapies were treated with a stable metformin/sitagliptin dual therapy for 20 weeks.The patients who did not reach the glycated hemoglobin A1c(HbA1c) goal were then further randomized into glimepiride,gliclazide,repaglinide,or acarbose group for an additional 24-week triple therapy.A mean HbAlc reduction of 0.85%was observed when sitagliptin was added to the patients inadequately controlled with metformin in 16 weeks.Further HbAlc reductions in the 24-week triple therapy stage were 0.65%in glimepiride group,0.70%in gliclazide group,0.61%in repaglinide group,and 0.45%in acarbose group.The non-inferiority criterion for primary hypotheses was met for gliclazide and repaglinide,but not for acarbose,compared with glimepiride,when added to metformin/sitagliptin dual therapy.The incidences of adverse events(AEs) were 29.2%in the dual therapy stage and30.3%in the triple therapy stage.Metformin/sitagliptin as baseline therapy,with the addition of a third oral antihyperglycemic agent,including glimepiride,gliclazide,repaglinide,or acarbose,was effective,safe and well-tolerated for achieving an HbAlc<7.0%goal in type 2 diabetic patients inadequately controlled with previous therapies.The timely augmentation of up to three oral antihyperglycemic agents is valid and of important clinical benefit to prevent patients from exposure to unnecessarily prolonged hyperglycemia. | Wen Xu Yiming Mu Jiajun Zhao Dalong Zhu Qiuhe Ji Zhiguang Zhou Bin Yao Anhua Mao Samuel S.Engel Bin Zhao Yan Bi Longyi Zeng Xingwu Ran Juming Lu Linong Ji Wenying Yang Weiping Jia Jianping Weng | 2017 | Science China(Life Sciences)2017，60，3： | 19 |
| 4 | Pollution of organic compounds and heavy metals in a coal gangue dump of the Gequan Coal Mine, China显示文摘Samples around a coal gangue dump of the Gequan Coal Mine were collected in April 2009. GC (gas chromatography) and GC/MS (gas chromatography/mass spectrometry) were employed to analyze the composition of organic matter in the samples. ICP-MS (inductively coupled plasma mass spectrometry) was used to determine the concentrations of heavy metals. The contents of organic extracts are within the range of 140-750 mg/kg. Alkand aro-ratios are relatively high. Compared to those of the background sample (GQ13 ), the contents of saturated hydrocarbon compounds in all the samples are relatively high. The contents of polycyclic aromatic hydrocarbons (PAHs) are relatively high with the distance getting closer to the coal gangue dump. These indicate that organic matter in the samples is from coal particles of the coal gangue dump. The distributions of heavy metals are very similar: the contents decrease with distance from the dump, which indicates that the harmful heavy metals from the coal gangue dump have polluted as thick as at least 500 m. | FAN Jingsen SUN Yuzhuang LI Xinyu ZHAO Cunliang TIAN Duanxin SHAO Longyi WANG Jinxi | 2013 | Chinese Journal Of Geochemistry2013，32，3： | 18 |

| 6 | Mineralogical characteristics of airborne particles collected in Beijing during a severe Asian dust storm period in spring 2002显示文摘Asian dust storm (ADS) samples were collected on March 20,2002 in Beijing,China. High-resolution field emission scanning electron microscopy with energy dispersive X-ray detector (FESEM-EDX) and X-ray diffraction (XRD) were used to study the morphology,chemical compositions,number-size dis-tributions and mineralogical compositions of ADS particles. The mineral particles were major compo-nents in the ADS samples,accounting for 94% by number. The XRD analysis indicated that the dust particles were dominated by clay (40.3%),and quartz (19.5%),followed by plagioclase (8.4%),calcite (7.5%),K-feldspar (1.5%),hematite (0.9%),pyrite (0.9%),hornblende (0.4%) and gypsum (0.3%),with a certain amount of noncrystalline materials (20.3%). Clay minerals were mainly illite/smectite mixed lay-ers (78%),followed by illite (9%),kaolinite (6%),and chlorite (7%). In addition to these main minerals,FESEM-EDX also detected some trace minerals,such as dolomite,pyrite,thenardite,as well as heavy minerals represented by rutile,ilmenite and apatite. The mineralogical compositions of the 2002-03-20 Asian dust storm and the Saharan dust plumes were similar but the clay mineralogy showed a great distinction,with the illite/smectite mixed layers being common in the Asian dust storm but illite being common in the Saharan dust plumes. | SHAO LongYi LI WeiJun YANG ShuShen SHI ZongBo LÜ SenLin | 2007 | Science China Earth Sciences2007，50，6： | 11 |
| 7 | Sequence Stratigraphy of the Jurassic Coal Measures in Northwestern China显示文摘The sequence stratigraphy of the Jurassic coal measures of northwestern China has been studied based on data from outcrop and borehole sections. Because of the geological background and the diversity of basin types, such as isochronisms of coal seams and recognition of key sequence boundaries, it is rare to summarize and correlate sequence structure and framework. The types and recognition characteristics of the sequence boundaries of the Jurassic coal measures are revealed by comparing climatic characteristics, structural styles and the base level cycle. A total of five third-order sequences and 15 systems tracts have been subdivided and the sequence stratigraphic framework has been reconstructed confirming that the thick coals accumulated in the late stage of transgression system tracts of sequence I (SQ I) and sequence III (SQ III). This idea is of important academic significance for instructing coal resources exploration, and enhancing geological effects of prospecting engineering. It is also of practical significance for guaranteeing construction of the large-scale coal production base in northwestern China, accelerating the westward development of the coal industry stratagem. | WANG Tong SHAO Longyi TIAN Ye LU Jing WANG Wenlong | 2012 | Acta Geologica Sinica(English Edition)2012，86，3： | 11 |
| 8 | Sequence stratigraphy, paleogeography, and coal accumulation regularity of major coal-accumulating periods in China显示文摘There are 9 major coal-accumulating periods during geological history in China,including the Early Carboniferous,Late Carboniferous-Early Permian,Middle Permian,Late Permian,Late Triassic,Early-Middle Jurassic,Early Cretaceous,Paleogene and Neogene.The coal formed in these periods were developed in different coal-accumulating areas(CAA)including the North China,South China,Northwest China,Northeast China,the Qinghai–Tibet area,and China offshore area.In this paper,we investigated depositional environments,sequence stratigraphy,lithofacies paleogeography and coal accumulation pattern of five major coal-accumulating periods including the Late Carboniferous to Middle Permian of the North China CAA,the Late Permian of the South China CAA,the Late Triassic of the South China CAA,the Early-Middle Jurassic of the North and Northwest China CAA,and the Early Cretaceous in the Northeast China CAA.According to distribution of the coal-bearing strata and the regional tectonic outlines,we have identified distribution range of the coal-forming basins,sedimentary facies types and coal-accumulating models.The sequence stratigraphic frameworks of the major coal-accumulating periods were established based on recognition of a variety of sequence boundaries.The distribution of thick coals and migration patterns of the coal-accumulating centers in the sequence stratigraphic framework were analyzed.The lithofacies paleogeography maps based on third-order sequences were reconstructed and the distribution of coal accumulation centers and coal-rich belts were predicted. | Longyi Shao Xuetian Wang Dongdong Wang Mingpei Li Shuai Wang Yingjiao Li Kai Shao Chao Zhang Caixia Gao Daxiao Dong Aiguo Cheng Jing Lu Congwei Ji Di Gao | 2020 | International Journal of Coal Science & Technology2020，7，2： | 9 |

| 10 | Decreased b-Cell Function is Associated with Cardiovascular Autonomic Neuropathy in Chinese Patients Newly Diagnosed with Type 2 Diabetes显示文摘The influence of b-cell function on cardiovascular autonomic neuropathy(CAN), an important diabetesrelated complication, is still unclear. In this study, we aimed to investigate the association between residual b-cell function and CAN in patients newly diagnosed with type 2 diabetes. We enrolled 90 newly-diagnosed type 2 diabetic patients and 37 participants with normal glucose tolerance as controls. The patients were divided into a CAN? group(diabetic patients with CAN, n = 20) and a CAN-group(diabetic patients without CAN, n = 70) according to the standard Ewing battery of tests. Fasting and postprandial plasma glucose, insulin, and C-peptide were measured.Homeostasis model assessment-beta cells(HOMA-B) and HOMA-insulin resistance(IR) were calculated. The prevalence of CAN in this population was 22.2%. Compared with the CAN-group, the CAN? group had significantly lower fasting plasma insulin(6.60 ± 4.39 vs 10.45 ± 7.82 l/L, P = 0.029), fasting C-peptide(0.51 ± 0.20 vs0.82 ± 0.51 nmol/L, P = 0.004), and HOMA-B(21.44 ± 17.06 vs 44.17 ± 38.49, P = 0.002). Fasting C-peptide was correlated with the Valsalva ratio(r = 0.24, P = 0.043) and the 30:15 test(r = 0.26,P = 0.023). Further analysis showed that fasting C-peptide(OR: 0.041, 95% CI 0.003–0.501, P = 0.012) and HOMAB(OR: 0.965, 95% CI 0.934–0.996, P = 0.028) were independently associated with cardiovascular autonomic nerve function in this population. The patients with fasting C-peptide values \ 0.67 nmol/L were more likely to have CAN than those with C-peptide levels C0.67 nmol/L(OR:6.00, 95% CI 1.815–19.830, P = 0.003). A high prevalence of CAN was found in patients with newly-diagnosed type 2 diabetes. Decreased b-cell function was closely associated with CAN in this population. | Xubin Yang Wen Xu Yanhua Zhu Hongrong Deng Ying Tan Longyi Zeng Jianping Weng | 2019 | Neuroscience Bulletin2019，35，1： | 7 |

| 12 | Depositional Model for Peat Swamp and Coal Facies Evolution Using Sedimentology, Coal Macerals, Geochemistry and Sequence Stratigraphy显示文摘As one of the most important source rocks and reservoirs of unconventional natural gas, the sedimentary environment and mode of peat swamp(the predecessor of coal seam) is important to the coal seam's spatial distribution, material composition, hydrocarbon generation potential, reservoir physical properties, etc. To reveal the depositional characteristics and history of environmental change in a terrestrial basin during a period of peat accumulation, the Middle Jurassic aged #7 coal from Gaoquan in the Qaidam Basin(NW China) was investigated using sedimentology, maceral composition, geochemistry and sequence stratigraphy. Based on identification of the sedimentary shoreline break belt, wave energy depletion point and position of wave base, the peat swamp system can be subdivided into(1) lakeside plain,(2) low energy lakeshore,(3) high energy lakeshore, and(4) shallow lake subfacies. A new method for determining coal facies is proposed based on the combination of environmental parameters including oxidation-reduction levels, energy conditions and the influence of terrigneous sediments. The evolution of the coal seam shows that peat was deposited mainly in the low energy lakeshore and lakeside plain subfacies. Five types of sequence stratigrpahic surface and two types of parasequence were identified. Forced lake regressions and normal lake regressions are attributed as the causes of sequence boundaries. The sequence stratigraphic framework comprises six sequences and corresponding system tracts, and the curve of base-level for each demonstrates a characteristic initial period of slow rising followed by fast rising and then returning to slow rising. A model indicating the relationship among base-level changes, coal facies evolution, and the environmental features in the swamp is proposed that shows the environmental features of the swamp were controlled by both base-level changes and coal facies. Accompanying depositional environment changes from a lakeside plain to lakeshore and shallow lake caused by increasing rate of base-level rise, water paleosalinity, acidity and the percentage of woody plants decrease, and the bog type alters from the low marsh to raised bog. | Jing Lu Longyi Shao Minfang Yang Kai Zhou James R.Wheeley Hao Wang Jason Hilton | 2017 | Journal of Earth Science2017，28，6： | 5 |
| 13 | Oxidative capacities of size-segregated haze particles in a residential area of Beijing显示文摘The frequent haze days around the Chinese capital of Beijing in recent years have aroused great attention owing to the detrimental efects on visibility and public health. To discover the potential health efects of the haze, oxidative capacities of airborne particles collected in Beijing during haze and clear days were comparably assessed by a plasmid scission assay. Eleven water-soluble trace elements(As, Cd, Cr, Cu, Mn, Ni, Pb, V, Se, Tl, and Zn) in the size-segregated airborne particles were quantitatively analyzed by inductively coupled plasma mass spectrometry, and most of the watersoluble trace elements were found to mainly concentrate in the fine particle size of 0.56–1.0 μm. In comparison with clear days, the mass concentrations of 11 analyzed water-soluble trace elements remarkably increased during haze days, and the oxidative capacities determined by the plasmid scission assay were markedly elevated accordingly during the haze days under the same dosage of particles as for those during clear days. Water-soluble trace elements in airborne particles, such as Cu, V, and particularly Zn, were found to have significantly positive correlations with the plasmid DNA damage rates. Because Cu, V, and Zn have been considered as bioavailable elements, the evident increase of these elements during haze days may be greatly harmful to human health. | Zhenquan Sun Longyi Shao Yujing Mu Ying Hu | 2014 | Journal of Environmental Sciences2014，26，1： | 5 |
| 14 | Influence of depositional environment on coalbed methane accumulation in the Carboniferous-Permian coal of the Qinshui Basin, northern China显示文摘Based on analyses of the lithofacies palaeo-geography of the Taiyuan and the Shanxi Formations in the Qinshui Basin, the spatial variations of the coal seam thickness, coal maceral composition, coal quality, and gas content, together with the lithofacies of the surrounding rocks in each palaeogeographic unit were investigated. The results show that the thick coals of the Taiyuan Formation are mainly distributed in delta and barrier island depositional units in the Yangquan area in the northern part of the basin and the Zhangzi area in the southeastern part of the basin. The thick coals of the Shanxi Formation are located within transitional areas between delta plain and delta front depositional units in the central southern part of the basin. The Taiyuan Formation generally includes mudstone in its lower part, thick, continuous coal seams and limestones in its middle part, and thin, discontinuous coal seams and limestone and sand-mud interbeds in its top part. The Shanxi Formation consists of thick, continuous sandstones in its lower part, thick coal seams in its middle part, and thin coal seams, sandstone, and thick mudstone in its upper part. From the perspective of coal-bearing sedimentology and coalbed methane (CBM) geology, the lithology and thickness of the surrounding rocks of coal seams play more significant roles in controlling gas content variation than other factors such as coal thickness, coal macerals, and coal quality. Furthermore, it is found that the key factors influencing the gas content variation are the thicknesses of mudstone and limestone overlying a coal seam. At similar burial depths, the gas content of the Taiyuan coal seams decreases gradually in the lower delta plain, barrier-lagoon,delta front, barrier-tidal flat, and carbonate platform depositional units. The CBM enrichment areas tend to be located in zones of poorly developed limestone and well-developed mudstone. In addition, the gas content of the Shanxi Formation is higher in the coals of the delta front facies compared to those in the lower delta plain. The CBM enrichment areas tend to be associated with the thicker mudstones. Therefore, based on the lithologic distribution and thickness of the rocks overlying the coal seam in each palaeogeographic unit of the Taiyuan and Shanxi Formations, the areas with higher gas content are located in the north-central basin for the Taiyuan coals and in the southern basin for the Shanxi coals. Both of these areas should be favorable for CBM exploration in the Qinshui Basin. | Haihai HOU Longyi SHAO Shuai WANG Zhenghui XIAO Xuetian WANG Zhen LI | 2019 | Frontiers of Earth Science2019，13，3： | 4 |
| 15 | Characteristics and Dolomitization of Upper Cambrian to Lower Ordovician Dolomite from Outcrop in Keping Uplift, Western Tarim Basin, Northwest China显示文摘Late Cambrian to Early Ordovician sedimentary rocks in the western Tarim Basin, Northwest China, are composed of shallow-marine platform carbonates. The Keping Uplift is located in the northwest region of this basin. On the basis of petrographic and geochemical features, four matrix replacement dolomites and one type of cement dolomite are identified. Matrix replacement dolomites include (1) micritic dolomites (MD1); (2) fine-coarse euhedral floating dolomites (MD2); (3) fine-coarse euhedral dolomites (MD3); and (4) medium-very coarse anhedral mosaic dolomites (MD4). Dolomite cement occurs in minor amounts as coarse saddle dolomite cement (CD1) that mostly fills vugs and fractures in the matrix dolomites. These matrix dolomites have δ18O values of ?9.7‰ to ?3.0‰ VPDB (Vienna Pee Dee Belemnite); δ13C values of ?0.8‰ to 3.5‰ VPDB; 87Sr/86Sr ratios of 0.708516 to 0.709643; Sr concentrations of 50 to 257 ppm; Fe contents of 425 to 16878 ppm; and Mn contents of 28 to 144 ppm. Petrographic and geochemical data suggest that the matrix replacement dolomites were likely formed by normal and evaporative seawater in early stages prior to chemical compaction at shallow burial depths. Compared with matrix dolomites, dolomite cement yields lower δ18O values (?12.9‰ to ?9.1‰ VPDB); slightly lower δ13C values (?1.6‰-0.6‰ VPDB); higher 87Sr/86Sr ratios (0.709165-0.709764); and high homogenization temperature (Th) values (98°C-225°C) and salinities (6 wt%-24 wt% NaCl equivalent). Limited data from dolomite cement shows a low Sr concentration (58.6 ppm) and high Fe and Mn contents (1233 and 1250 ppm, respectively). These data imply that the dolomite cement precipitated from higher temperature hydrothermal salinity fluids. These fluids could be related to widespread igneous activities in the Tarim Basin occurring during Permian time when the host dolostones were deeply buried. Faults likely acted as important conduits that channeled dolomitizing fluids from the underlying strata into the basal carbonates, leading to intense dolomitization. Therefore, dolomitization, in the Keping Uplift area is likely related to evaporated seawater via seepage reflux in addition to burial processes and hydrothermal fluids. | JI Congwei QING Hairuo CHEN Daizhao LUO Ping JIN Zhijun SHAO Longyi | 2013 | Acta Geologica Sinica(English Edition)2013，87，4： | 4 |
| 16 | Morphology and composition of particles emitted from a port fuel injection gasoline vehicle under real-world driving test cycles显示文摘Traffic vehicles, many of which are powered by port fuel injection(PFI) engines, are major sources of particulate matter in the urban atmosphere. We studied particles from the emission of a commercial PFI-engine vehicle when it was running under the states of cold start, hot start, hot stabilized running, idle and acceleration, using a transmission electron microscope and an energy-dispersive X-ray detector. Results showed that the particles were mainly composed of organic, soot, and Ca-rich particles, with a small amount of S-rich and metal-containing particles, and displayed a unimodal size distribution with the peak at 600 nm. The emissions were highest under the cold start running state, followed by the hot start, hot stabilized, acceleration, and idle running states. Organic particles under the hot start and hot stabilized running states were higher than those of other running states. Soot particles were highest under the cold start running state. Under the idle running state, the relative number fraction of Ca-rich particles was high although their absolute number was low. These results indicate that PFI-engine vehicles emit substantial primary particles,which favor the formation of secondary aerosols via providing reaction sites and reaction catalysts, as well as supplying soot, organic, mineral and metal particles in the size range of the accumulation mode. In addition, the contents of Ca, P, and Zn in organic particles may serve as fingerprints for source apportionment of particles from PFI-engine vehicles. | Jiaoping Xing Longyi Shao Wenbin Zhang Jianfei Peng Wenhua Wang Cong Hou Shijin Shuai Min Hu Daizhou Zhang | 2019 | Journal of Environmental Sciences2019，31，2： | 4 |
| 17 | Current Status of the Research on Coal Geology in China显示文摘Coal is the main energy in China, which has already played and will continue to play an important role in the national economy.

| 20 | Dual Control of Depositional Facies on Uranium Mineralization in Coal-bearing Series: Examples from the Tuanyushan Area of the Northern Qaidam Basin, NW China显示文摘The uranium deposits in the Tuanyushan area of northern Qaidam Basin commonly occur in coal-bearing series. To decipher the U-enrichment mechanism and controlling factors in this area, a database of 72 drill cores, including 56 well-logs and 3 sampling wells, was examined for sedimentology and geochemistry in relation to uranium concentrations. The results show that coal-bearing series can influence uranium mineralization from two aspects, i.e., spatial distribution and dynamic control. Five types of uranium-bearing rocks are recognized, mainly occurring in the braided river and braided delta sedimentary facies, among which sandstones near the coals are the most important. The lithological associations of sandstone-type uranium deposits can be classified into three subtypes, termed as U-coal type, coal-U-coal type, and coal-U type, respectively. The coal and fine siliciclastic rocks in the coalbearing series confined the U-rich fluid flow and uranium accumulation in the sandstone near them. Thus, the coal-bearing series can provide good accommodations for uranium mineralization. Coals and organic matters in the coal-bearing series may have served as reducing agents and absorbing barriers. Methane is deemed to be the main acidolysis hydrocarbon in the U-bearing beds, which shows a positive correlation with U-content in the sandstones in the coal-bearing series. Additionally, the δ13 C in the carbonate cements of the U-bearing sandstones indicates that the organic matters, associated with the coal around the sandstones, were involved in the carbonation, one important component of alteration in the Tuanyushan area. Recognition of the dual control of coal-bearing series on the uranium mineralization is significant for the development of coal circular economy, environmental protection during coal utilization and the security of national rare metal resources. | GUO Biao SHAO Longyi WEN Huaijun HUANG Guangnan ZOU Mingjun LI Yonghong | 2018 | Acta Geologica Sinica(English Edition)2018，92，2： | 2 |
