| 1 | Characteristics of secondary inorganic aerosol and sulfate species in size-fractionated aerosol particles in Shanghai显示文摘Sulfate, nitrate and ammonium(SNA) are the dominant species in secondary inorganic aerosol, and are considered an important factor in regional haze formation. Size-fractionated aerosol particles for a whole year were collected to study the size distribution of SNA as well as their chemical species in Shanghai. SNA mainly accumulated in fine particles and the highest average ratio of SNA to particulate matter(PM) was observed to be 47% in the fine size fraction(0.49–0.95 μm). Higher sulfur oxidation ratio and nitrogen oxidation ratio values were observed in PM of fine size less than 0.95 μm. Ion balance calculations indicated that more secondary sulfate and nitrate would be generated in PM of fine size(0.49–0.95 μm). Sulfur K-edge X-ray absorption near-edge structure(XANES) spectra of typical samples were analyzed. Results revealed that sulfur mainly existed as sulfate with a proportion(atomic basis) more than 73% in all size of PM and even higher at 90% in fine particles. Sulfate mainly existed as(NH4)2SO4 and gypsum in PM of Shanghai. Compared to non-haze days, a dramatic increase of(NH4)2SO4 content was found in fine particles on haze days only, which suggested the promoting impact of(NH4)2SO4 on haze formation. According to the result of air mass backward trajectory analysis, more(NH4)2SO4 would be generated during the periods of air mass stagnation. Based on XANES, analysis of sulfate species in size-fractionated aerosol particles can be an effective way to evaluate the impact of sulfate aerosols on regional haze formation. | Shilei Long Jianrong Zeng Yan Li Liangman Bao Lingling Cao Ke Liu Liang Xu Jun Lin Wei Liu Guanghua Wang Jian Yao Chenyan Ma Yidong Zhao | 2014 | Journal of Environmental Sciences2014，26，5： | 10 |
| 2 | Urban Green Space Planning Based on Computational Fluid Dynamics Model and Landscape Ecology Principle:A Case Study of Liaoyang City,Northeast China显示文摘As a result of environmental degradation,urban green space has become a key issue for urban sustainable development.This paper takes Liaoyang City in Northeast China as an example to develop green space planning using the computational fluid dynamics (CFD) model,landscape ecological principles and Geographical Information System (GIS).Based on the influencing factors of topography,building density and orientation,Shou Mountain,Longding Mountain and the Taizi River were selected as the urban ventilation paths to promote wind and oxygen circulation.Oxygen concentration around the green spaces gradually decreased with wind speed increase and wind direction change.There were obvious negative correlation relationships between the oxygen dispersion concentration and urban layout factors such as the building plot ratio and building density.Comparison with the field measurements found that there was significant correlation relationship between simulated oxygen concentration and field measurements (R 2=0.6415,p<0.001),moreover,simulation precision was higher than 92%,which indicated CFD model was effective for urban oxygen concentration simulation.Only less than 10% areas in Liaoyang City proper needed more green space urgently to improve oxygen concentration,mainly concentrated in Baitai and west Wensheng districts.Based on land-scape ecology principle,green space planning at different spatial scales were proposed to create a green space network system for Liaoyang City,including features such as green wedges,green belts and parks.Totally,about 2012 ha of green space need to be constructed as oxygen sources and ventilation paths.Compared with the current green space pattern,proposed green space planning could improve oxygen concentration obviously.The CFD model and research results in this paper could provide an effective way and theory support for sustainable development of urban green space. | ZHOU Yuan SHI Tiemao HU Yuanman GAO Chang LIU Miao FU Shilei WANG Shizhe | 2011 | Chinese Geographical Science2011，21，4： | 9 |
| 3 | Cromakalin pretreatment affects mitochondrial structure and function in a rat model of ischemia/reperfusion injury显示文摘BACKGROUND:Mitochondrial structural changes and energy dysmetabolism frequently occur subsequent to cerebral ischemia.Adenosine triphosphate(ATP)-sensitive potassium channel openers exhibit protective effects on cerebral ischemia/reperfusion injury.OBJECTIVE:To validate the effects of cromakalin on mitochondrial structure and function in ischemic penumbra brain tissue in a rat model of middle cerebral artery occlusion(MCAO).DESIGN,TIME AND SETTING:The present single-factor analysis of variance,randomized,controlled,animal experiment was performed at the Institute of Brain Science,Affiliated Hospital of Qingdao University Medical College between October 2007 and March 2008.MATERIALS:Forty male,Wistar rats were randomly divided into four groups,with 10 rats per group:sham-operated,MCAO,MCAO+ATP-sensitive potassium channel opener(cromakalin),and MCAO+cromakalin+ATP-sensitive potassium channel blocking agent(glibenclamide).METHODS:Focal cerebral ischemia/reperfusion injury was induced by MCAO in all groups except the sham-operated group.The MCAO cromakalin group was administered 10 mg/kg cromakalin(i.p.) prior to MCAO induction.The MCAO+cromakalin+glibenclamide group received an injection of 10 mg/kg cromakalin(i.v.),and subsequently an injection of 10 mg/kg cromakalin(i.p.) prior to MCAO induction.MAIN OUTCOME MEASURES:At 24 hours after cerebral ischemia/reperfusion injury,cellular apoptosis was detected by terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate(dUTP) nick-end labeling technique.Cytochrome C expression was measured by immunohistochemistry.In addition,mitochondrial swelling,membrane fluidity,membrane phospholipid and malonaldehyde(MDA) contents,as well as Na+-K+-ATPase,Ca2 +-ATPase,and superoxide dismutase(SOD) activities were determined.RESULTS:Compared with the sham-operated group,the three ischemia groups exhibited significantly elevated mitochondrial MDA content,reduced membrane phospholipid and ATP contents,down-regulated membrane fluidity,and reduced Na+-K+-ATPase,Ca2+-ATPase,and SOD activities(P < 0.05-0.01).In the MCAO+cromakalin group,the number of apoptotic cells decreased,and cytochrome C expression,as well as MDA content,were reduced.However,ATP content and Na+-K+-ATPase,Ca2+-ATPase,and SOD activities significantly increased compared with the MCAO group(P < 0.05-0.01).Glibenclamide noticeably antagonized cromakalin protection of mitochondria.CONCLUSION:Pretreatment with the ATP-sensitive potassium channel opener cromakalin increased mitochondrial Na+-K+-ATPase,Ca2+-ATPase,and SOD activities,decreased neuronal apoptosis,and inhibited cytochrome C expression following MCAO. | Shilei Wang Peng Wang Qingxian Chang Yu Li Yan Jiang Shiduan Wang | 2008 | Neural Regeneration Research2008，3，9： | 6 |
| 4 | Deformation-induced martensitic transformation kinetics and correlative micromechanical behavior of medium-Mn transformation-induced plasticity steel显示文摘An in situ high-energy X-ray diffraction(HE-XRD) technique was mainly used to investigate the micromechanical behavior of medium-Mn Fe-0.12 C-10.16 Mn-1.87 Al(in wt%) transformation-induced plasticit(TRIP) steel subjected to intercritical annealing at 625℃, 650℃, 675℃ and 700℃ for 1 h. As the intercritical annealing temperature increased, the volume fraction of retained austenite(RA) and ultimate tensilstress(UTS) increased, while the Lüders strain and yield stress(YS) decreased. The incremental workhardening exponent of experimental steel increased with increasing intercritical annealing temperatureThe overall trend of the transformation kinetics of the RA with respect to the true strain followed thsigmoidal shape predicted by the Olson and Cohen(OC) model. Load partitioning occurred among the ferrite, austenite and martensite immediately after entering the yielding stage. Because the stability of thRA decreased with increasing intercritical annealing temperature, the load undertaken by the martensitincreased. The moderate transformation kinetics of the RA and effective load partitioning among constituent phases were found to contribute to a favorable combination of strength and ductility for thimedium-Mn TRIP steel. | Minghe Zhang Haiyang Chen Youkang Wang Shengjie Wang Runguang Li Shilei Li Yan-Dong Wang | 2019 | Journal of Materials Science & Technology2019，35，8： | 5 |
| 5 | A Modular DC/DC Photovoltic Generation System for HVDC Grid Connection显示文摘A modular DC/DC conversion system with distributed MPPT and centralized step-up converter for photovoltaic energy integrated into HVDC grids is proposed in this paper.The conversion system consists of two power stages,with MPPT converter as the first stage and a step-up converter as the second stage.Both stages are modular structures.For the distributed MPPT stage,interleaved boost topology is utilized to effectively reduce the input and output ripples without adding extra components.For the centralized step-up stage,narrow-switching-frequency-variation LLC topology is employed,with the modules being configured as input-parallel-output-series structure.Full-range soft-switching property is achieved in the LLC stage to minimize switching losses.Theoretical analysis is carried out for the system voltage gain and design principles.Simulation and experimental results of a 3kW prototype system are presented to verify the theoretical analysis of the proposed system. | Guoen Cao Kai Sun Siyue Jiang Shilei Lu Yibo Wang | 2018 | Chinese Journal of Electrical Engineering2018，4，2： | 5 |
| 6 | Effects of the mitochondrial calcium uniporter on cerebral edema in a rat model of cerebral ischemia reperfusion injury显示文摘The present study investigated the effects of the mitochondrial calcium uniporter inhibitor ruthenium red and the agonist spermine on cerebral edema in rats with cerebral ischemia reperfusion injury. Left middle cerebral artery occlusion (MCAO) was induced in rats using the suture method. Following 24 hours of ischemic reperfusion, neurological function scores of rats with MCAO, and rats pretreated with ruthenium red and spermine were significantly lower, however, water content of brain tissue, aquaporin 4 expression and immunoglobulin G (IgG) exudation were significantly higher than those of sham-operated rats. Compared with MCAO rats and spermine-treated rats, neurological function scores were considerably higher, and brain tissue water content, aquaporin 4 expression and IgG exudation decreased in ruthenium red-treated rats. These findings suggest that preventive application of the mitochondrial calcium uniporter inhibitor ruthenium red can significantly decrease aquaporin 4 and IgG expression, influence the permeability of the blood brain barrier, and thereby decrease the extent of cerebral edema. | Linlin Li Shilei Wang Haihong Luan | 2011 | Neural Regeneration Research2011，6，22： | 4 |
| 7 | Fingerprinting hydrothermal fluids in porphyry Cu deposits using K and Mg isotopes显示文摘In this study, we performed an integrated investigation of K and Mg isotopes in hydrothermally altered rocks from the giant Dexing porphyry Cu deposit in China. Both the altered porphyry intrusion and the surrounding wall rocks exhibit large variations in K and Mg isotope compositions, with δ41K values ranging between-1.02‰ and 0.38‰, and δ26Mg values ranging between-0.49‰ and 0.32‰. The δ41K and δ26Mg values of the majority of altered samples are higher than the isotopic baseline values for upper continental crust. We attribute the general increase in δ41 K and δ26Mg in altered rocks to hydrothermal alteration,which caused preferential incorporation of heavy K and Mg isotopes in alteration products, particularly phyllosilicates. However,a few altered samples show anomalously low δ41K and δ26Mg values. The δ41K and δ26Mg values do not correlate with K and Mg concentrations, or mineralogy of altered samples. The variable K-Mg isotope data likely reflect fluids of different physicalchemical properties, or different isotopic compositions. Based on the combined K-Mg isotope data, at least three groups of hydrothermal fluids are distinguished from the Dexing porphyry deposit. Therefore, K-Mg isotopes are potentially a novel tracer for fingerprinting fluids in complex hydrothermal systems. | Weiqiang LI Shugao ZHAO Xiaomin WANG Shilei LI Guoguang WANG Tao YANG Zhangdong JIN | 2020 | Science China Earth Sciences2020，63，1： | 4 |
| 8 | The energy performance and passive survivability of high thermal insulation buildings in future climate scenarios显示文摘Given that the passive performance simulation of buildings based on typical meteorological year data and specific design schemes makes it challenging to respond to climate change and refine design requirements on time,this article established a passive performance prediction model for future buildings considering multi-dimensional variables including climate change,building design,and operational characteristics.For high thermal insulation buildings under future climates,the mild climate zone is more sensitive than the others,cooling energy demand is more sensitive than heating demand,apartments are more sensitive than office buildings,and passive survivability is more sensitive than energy performance;for buildings of the same type located in the same climate zone,thermal design solutions determine the increase rate of cooling demand.The potential benefits of climate warming on heating demand reduction are almost zero,but the cooling demand increases significantly,with apartments and office buildings increasing up to 22.1% and 5.0%,respectively.Buildings generally overheat in the future,and the increase rate of the mild zone far exceeds other zones with duration and severity being 3004.8% and 877.7%for apartments,and 884.3% and 288.9%for office buildings,respectively. | Ran Wang Shilei Lu Xue Zhai Wei Feng | 2022 | Building Simulation2022，15，7： | 4 |
| 9 | The calcium uniporter regulates the permeability transition pore in isolated cortical mitochondria显示文摘To investigate the influence of the mitochondrial calcium uniporter on the mitochondrial permeability transition pore, the present study observed mitochondrial morphology in cortical neurons isolated from adult rats using transmission electron microscopy, and confirmed the morphology and activity of isolated mitochondria by detecting succinic dehydrogenase and monoamine oxidase, two mitochondrial enzymes. Isolated mitochondria were treated with either ruthenium red, an inhibitor of the uniporter, spermine, an activator of the uniporter, or in combination with cyclosporin A, an inhibitor of the mitochondrial permeability transition pore. Results showed that ruthenium red inhibited CaCl2-induced mitochondrial permeability transition pore opening, spermine enhanced opening, and cyclosporin A attenuated the effects of spermine. Results demonstrated that the mitochondrial calcium uniporter plays a role in regulating the mitochondrial permeability transition pore in mitochondria isolated from the rat brain cortex. | Ning Yu Shilei Wang Peng Wang Yu Li Shuhong Li Li Wang Hongbing Chen Yanting Wang | 2012 | Neural Regeneration Research2012，7，2： | 4 |

| 12 | Recent progress in terahertz modulation using photonic structures based on two-dimensional materials显示文摘Terahertz(THz)technology has attracted great attention in the past few decades for its unique applications in various fields,including spectroscopy,noninvasive detection,wireless communications,and imaging.In parallel to this,the practical,fast,and broadband modulation of THz waves is becoming indispensable.Two-dimensional(2D)materials exhibit unusual optical and electrical properties,which has prompted tremendous interest and significant advances in THz modulation.This review provides the recent progress in 2D materials-based THz modulators,outlining the operating principles,including all-optical,electro-optic,magneto-optic,and other exotic mechanisms.We focus on the recent advances in THz modulation by the designed photonic structures,such as heterostructure,metamaterial,capacitor,optical cavity,and waveguide integration.Lastly,we discussed the challenges and opportunities for 2D materials-based THz modulators and presented our prospects for the future development. | Ziming Wang Jie Qiao Shuqi Zhao Shilei Wang Chuan He Xutang Tao Shanpeng Wang | 2021 | InfoMat2021，3，10： | 4 |
| 13 | Prognostic significance of combining high mobility group Box-1 and OV-6 expression in hepatocellular carcinoma显示文摘The inflammatory environment and existence of cancer stem cells are critical for progression and intrahepatic recurrence of hepatocellular carcinoma(HCC) after curative resections. Here, we investigated the prognostic significance of combining high mobility group box 1(HMGB1) expression and hepatic progenitor marker OV6 in hepatocellular carcinoma. Expression of HMGB1 and OV6 was evaluated using immunohistochemistry profiling in tissue microarrays containing samples from 208 HCC patients. Invasive clinical or pathological factors were found in patients with high expression of HMGB1 or OV6. Higher HMGB1 was associated with poorer clinical outcomes, and independently related to elevated 5-year recurrence incidence(85.5% vs. 62.4%, P<0.001). We also found that more OV6 positive staining was correlated with poor prognosis of HCC patients(P<0.001). Notably, expression of HMGB1 was positively correlated with OV6 in density(R2=0.032, P<0.001) and reversely related to HCC outcomes. Abnormal expression of HMGB1 in combination with positive staining of OV6 displayed poorer prognostic performance than single biomarker alone(area under curve(AUC) survival=0.696). Therefore, HMGB1 and OV6 positive staining are promising prognostic parameters for HCC, and we propose that HMGB1 and OV6 may cooperate with each other and predict poor prognosis of HCC. | Jihui Zhu Han Yu Shuzhen Chen Pinghua Yang Zihui Dong Yan Ling Hao Tang Shilei Bai Wen Yang Liang Tang Feng Shen Hongyang Wang Wen Wen | 2018 | Science China(Life Sciences)2018，61，8： | 4 |
| 14 | Retina-Inspired Organic Heterojunction-Based Optoelectronic Synapses for Artificial Visual Systems显示文摘For the realization of retina-inspired neuromorphic visual systems which simulate basic functions of human visual systems,optoelectronic synapses capable of combining perceiving,processing,and memorizing in a single device have attracted immense interests.Here,optoelectronic synaptic transistors based on tris(2-phenylpyridine)iridium(Ir(ppy)_(3))and poly(3,3-didodecylquarterthiophene)(PQT-12)heterojunction structure are presented.The organic heterojunction serves as a basis for distinctive synaptic characteristics under different wavelengths of light.Furthermore,synaptic transistor arrays are fabricated to demonstrate their optical perception efficiency and color recognition capability under multiple illuminating conditions.The wavelength-tunability of synaptic behaviors further enables the mimicry of mood-modulated visual learning and memorizing processes of humans.More significantly,the computational dynamics of neurons of synaptic outputs including associated learning and optical logic functions can be successfully demonstrated on the presented devices.This work may locate the stage for future studies on optoelectronic synaptic devices toward the implementation of artificial visual systems. | Junyao Zhang Yang Lu Shilei Dai Ruizhi Wang Dandan Hao Shiqi Zhang Lize Xiong Jia Huang | 2021 | Research2021，，1： | 3 |
| 15 | Porcine skeletal muscle tissue fabrication for cultured meat production using three-dimensional bioprinting technology显示文摘Cultured meat produced through in vitro cell culture technology is regarded as a technical revolution.In this study,three-dimensional(3D)bioprinting technology was used to mimic the growth environment in vivo and construct a 3D culture system in vilro.Hydroge1 bioinks,namely,sodium alginate-gelatin and gelatin-methacrylate(GelMA)-silk fbroin,produced using two different curing processes were blended,and their rheological properties,mechanical properties,and biocompatibilities were compared.The 4%GelMA-20%silk fibroin hydroge1(GS2)demonstrated good performance and was hybridized with porcine skeleta1 muscle satellite cells for 3D printing to construct network structures of size 15 mm×15 mm and porosity 1000 um in 4-,6-,and 8-1ayer struchures.After 16 days of culture,4-and 6-1ayer grid structures formed compact muscle fbers organized by multinucleated myotubes.These results suggested that 3D bioprinting and GeIMA-silk fbroin hydrogels have great potential in fabricating porcine skeleta1 muscle tissue for use as cultured meat. | Yingying Li Wenting Liu Shilei Li Mingyue Zhang Feng Yang Shouwei Wang | 2021 | Journal of Future Foods2021，1，1： | 3 |
| 16 | Cholecystokinin octapeptide antagonizes apoptosis in human retinal pigment epithelial cells显示文摘Although cholecystokinin octapeptide-8 is important for neurological function, its neuroprotective properties remain unclear. We speculated that cholecystokinin octapeptide-8 can protect human retinal pigment epithelial cells against oxidative injury. In this study, retinal pigment epithelial cells were treated with peroxynitrite to induce oxidative stress. Peroxynitrite triggered apoptosis in these cells, and increased the expression of Fas-associated death domain, Bax, caspase-8 and Bcl-2. These changes were suppressed by treatment with cholecystokinin octapeptide-8. These results suggest that cholecystokinin octapeptide-8 can protect human retinal pigment epithelial cells against apoptosis induced by peroxynitrite. | Yuan Liu Yueling Zhang Zhaohui Gu Lina Hao Juan Du Qian Yang Suping Li Liying Wang Shilei Gong | 2014 | Neural Regeneration Research2014，9，14： | 2 |
| 17 | Neuroprotective effects of cromakalim on cerebral ischemia-reperfusion injury in rats Correlation with hippocampal metabotropic glutamate receptor 1 alpha and glutamate transporter 1显示文摘BACKGROUND:Studies have reported that potassium channel openers exhibit a protective effect on cerebral ischemia-reperfusion injury and inhibit glutamate excitotoxicity in rats.However,the effects of the glutamate receptor 1α and glutamate transporter 1 remain poorly understood.OBJECTIVE:To investigate the prophylactic use of the adenosine triphosphate-sensitive potassium channel opener cromakalim on neurological function and cerebral infarct size,as well as glutamate receptor 1α and glutamate transporter 1 expression,in rats with cerebral ischemia-reperfusion injury,and to explore action mechanisms underlying reduced glutamate excitotoxicity and neuroprotection in rats.DESIGN,TIME AND SETTING:Randomized,controlled,animal experiment was performed at the Brain Institute,Qingdao University Medical College,Between July 2008 and April 2009.MATERIALS:Cromakalim was purchased from Sigma,USA;rabbit anti-glutamate receptor 1α polyclonal antibody was offered by Wuhan Boster,China;rabbit anti-glutamate transporter 1 polyclonal antibody was offered by Santa Cruz Biotechnology,USA.METHODS:Sixty male,Wistar rats,aged 6 months,were randomly assigned to three groups (n= 20):sham-surgery,model,and cromakalim.Intraluminal thread methods were used to establish middle cerebral artery occlusion in rats from the model and cromakalim groups.Rats from the sham-surgery group were subjected to exposed common carotid artery,external carotid artery,and internal carotid artery,without occlusion.Cromakalim (10 mg/kg) was administered 30 minutes prior to middle cerebral artery occlusion,but there was no intervention in the model and sham-surgery groups.MAIN OUTCOME MEASURES:At 24 hours post-surgery,neurological behavioral functions were evaluated using Bederson's test,cerebral infarction volume was determined following tetrazolium chloride staining,and glutamate receptor 1α and glutamate transporter 1 expressions were detected using immunohistochemistry.RESULTS:Following cerebral ischemia-reperfusion injury,neurological behavioral malfunctions were obvious in all mice.Focal cerebral infarction was detected in ischemic hemispheres,glutamate receptor 1α expression increased,and glutamate transporter 1 expression decreased in the ischemic hemisphere (P < 0.05).Compared with the model group,neurological behavioral functions significantly improved,cerebral infarction volume was significantly reduced (P < 0.05),glutamate receptor 1α expression was significantly decreased,and glutamate transporter 1 expression was increased in the cromakalim group (P < 0.05).CONCLUSION:Improved neurological function and reduced cerebral infarction volume in rats through the preventive use of cromakalim could be related to decreased glutamate receptor 1α expression and enhanced glutamate transporter 1 expression. | Shilei Wang Junchao Liu Qingxian Chang Yu Li, Yan Jiang Shiduan Wang | 2010 | Neural Regeneration Research2010，5，9： | 2 |

| 20 | Tradeoff between heating energy demand in winter and indoor overheating risk in summer constrained by building standards显示文摘Evidence indicates that improvement of thermal performance of building envelope has the potential for aggravating the indoor overheating risk in summer. On the other hand, evolving building standards continue to strengthen the requirements for thermal performance to achieve the energy-saving target. Therefore, this study quantifies the interaction effect between building standards-oriented building design, heating energy demand in winter, and indoor overheating risk in summer. Building databases with different energy efficiency levels are generated using a randomly generated method. Uncertain variables include not only 13 design parameters but also the running state of natural ventilation and external shading. The indoor overheating risk is assessed in terms of severity and duration. Finally, a multi-objective optimization model integrating metamodels and the non-dominated sorting genetic algorithm is proposed to balance heating energy demand in winter and indoor overheating risk in summer. Results indicate that building standards tend to aggravate overheating risk in summer: the duration and severity of high-performance buildings increased by 40.6% and 24.2% than that of conventional-performance buildings. However, window ventilation could offset the adverse effect, and mitigation of duration and severity can be up to 85.2% and 62.1% for high-performance buildings. Window ventilation can weaken the conflict between heating energy demand in winter and overheating risk in summer. As heating energy demand increased from 6.1 to 67.3 kWh/m^(2), the overheating risk changes little that the duration of overheating risk decreased from 17.5% to 15.6% and severity decreased from 8.7 ℃ to 8.3 ℃. | Ran Wang Shilei Lu Wei Feng Bowen Xu | 2021 | Building Simulation2021，14，4： | 2 |
