| 1 | Chinese Trauma Surgeon Association for management guidelines of vacuum sealing drainage application in abdominal surgeries-Update and systematic review显示文摘Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chin ese Trauma Surge on Associati on orga nized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries.Eleven questions regarding the use of VSD in abdominal surgeries were addressed:(1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions?(2) Can VSD be preventively used for a high-risk abdominal incision w让h primary suture?(3) Can VSD be used in severely contaminated/infected abdominal surgical sites?(4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome?(5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage?(6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula?(7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess?(8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects?(9) Does VSD in crease the risk of bleeding?(10) Does VSD increase the risk of intestinal wail injury?(11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure. | Yang Li Pei-Yuan Li Shi-Jing Sun Yuan-Zhang Yao Zhan-Fei Li Tao Liu Fan Yang Lian-Yang Zhang Xiang-Jun Bai Jing-Shan Huo Wu-Bing He Jun Ouyang Lei Peng Ping Hu Yan-An Zhu Ping Jin Qi-Feng Shao Yan-Feng Wang Rui-Wu Dai Pei-Yang Hu Hai-Ming Chen Ge-Fei Wang Yong-Gao Wang Hong-Xu Jin Chang-Ju Zhu Qi-Yong Zhang Biao Shao Xi-Guang Sang Chang-Lin Yin | 2019 | Chinese Journal of Traumatology2019，22，1： | 26 |

| 5 | Electro-mechanically controlled assembly of reconfigurable 3D mesostructures and electronic devices based on dielectric elastomer platforms显示文摘The manufacture of 3D mesostructures is receiving rapidly increasing attention,because of the fundamental significance and practical applications across wide-ranging areas.The recently developed approach of buckling-guided assembly allows deterministic formation of complex 3D mesostructures in a broad set of functional materials;with feature sizes spanning nanoscale to centimeter-scale.Previous studies mostly exploited mechanically controlled assembly platforms using elastomer substrates;which limits the capabilities to achieve on-demand local assembly;and to reshape assembled mesostructures into distinct 3D configurations.This work introduces a set of design concepts and assembly strategies to utilize dielectric elastomer actuators as powerful platforms for the electro-mechanically controlled 3D assembly.Capabilities of sequential-local loading with desired strain distributions allow access to precisely tailored 3D mesostructures that can be reshaped into distinct geometries,as demonstrated by experimental and theoretical studies of?30 examples.A reconfigurable inductive-capacitive radio-frequency circuit consisting of morphable 3D capacitors serves as an application example. | Wenbo Pang Xu Cheng Haojie Zhao Xiaogang Guo Ziyao Ji Guorui Li Yiming Liang Zhaoguo Xue Honglie Song Fan Zhang Zheng Xu Lei Sang Wen Huang Tiefeng Li Yihui Zhang | 2020 | National Science Review2020，7，2： | 8 |
| 6 | An investigation of the effects of dust storms on rat lung using HRCT and blood gas analysis显示文摘The increasing intensity and frequency of sand-dust storms in China has led to greater prominence of associated environmental and health issues. Many studies have focused on the health effects of air particulate contaminants, but few formal investigations have studied the effects of sand-dust storms on human and animal health. The aim of this study was to investigate the effects of dust storms on rat lung by using high resolution computed tomography(HRCT) and blood gas analysis through a wind tunnel simulating. We found that the rat lung damage effects can be detected by the HRCT imaging after exposure to sand-dust storm environments, but had no obvious result through blood gas analysis. Exposure durations positively correlated with the damage degree to lung tissue. These will provide some evidence for clinical diagnosis of non-occupational pneumoconiosis. | FengFeng Lei WanYin Luo ZhiBao Dong YingZhu Sang LiZhu Luo Gang Huang Hua Liu QiZhang Chen | 2016 | Research in Cold and Arid Regions2016，8，4： | 5 |
| 7 | Microstructural Evolution and Oxidation Resistance of Multi-walled Carbon Nanotubes in the Presence of Silicon Powder at High Temperatures显示文摘The microstructural evolution and oxidation resistance of multi-walled carbon nanotubes(MWCNTs) by directly heating silicon powder and MWCNTs in a coke bed from 1000 to 1500 ℃ are investigated with the aid of X-ray diffraction(XRD),scanning electron microscopy(SEM),high resolution transmission electron microscopy(HRTEM) and thermogravimetry-differential scanning calorimetry(TG-DSC).The results showed that the morphology and microstructure of MWCNTs did not change much after being treated from 1000 ℃ to 1200 ℃.An obvious SiC coating was formed on the surface of MWCNTs from 1300 to 1400 ℃.Up to 1500 ℃,nearly all the MWCNTs transformed into SiC nanowires.The oxidation resistance of the treated MWCNTs was improved compared with as-received ones.Non-isothermal kinetics showed that the oxidation activation energy of the treated MWCNTs reached 208 kJ/mol,much higher than 164 kJ/mol of as-received ones. | Ming LUO Yawei Li Shengli Jin Shaobai Sang Lei Zhao | 2012 | Journal of Materials Science & Technology2012，28，7： | 5 |
| 8 | Screening Helicobacter pylori genes induced during infection of mouse stomachs显示文摘AIM:To investigate the effect of in vivo environment on gene expression in Helicobacter pylori(H.pylori) as it relates to its survival in the host.METHODS:In vivo expression technology(IVET) systems are used to identify microbial virulence genes.We modified the IVET-transcriptional fusion vector,pIVET8,which uses antibiotic resistance as the basis for selection of candidate genes in host tissues to develop two unique IVET-promoter-screening vectors,pIVET11 and pIVET12.Our novel IVET systems were developed by the fusion of random Sau3A DNA fragments of H.pylori and a tandem-reporter system of chloramphenicol acetyltransferase and beta-galactosidase.Additionally,each vector contains a kanamycin resistance gene.We used a mouse macrophage cell line,RAW 264.7 and mice,as selective media to identify specific genes that H.pylori expresses in vivo.Gene expression studies were conducted by infecting RAW 264.7 cells with H.pylori.This was followed by real time polymerase chain reaction(PCR) analysis to determine the relative expression levels of in vivo induced genes.RESULTS:In this study,we have identified 31 in vivo induced(ivi) genes in the initial screens.These 31 genes belong to several functional gene families,including several well-known virulence factors that are expressed by the bacterium in infected mouse stomachs.Virulence factors,vacA and cagA,were found in this screen and are known to play important roles in H.pylori infection,colonization and pathogenesis.Their detection validates the efficacy of these screening systems.Some of the identified ivi genes have already been implicated to play an important role in the pathogenesis of H.pylori and other bacterial pathogens such as Escherichia coli and Vibrio cholerae.Transcription profiles of allivi genes were confirmed by real time PCR analysis of H.pylori RNA isolated from H.pylori infected RAW 264.7 macrophages.We compared the expression profile of H.pylori and RAW 264.7 coculture with that of H.pylori only.Some genes such as cag A,vac A,lpx C,mur I,tlp C,trx B,sod B,tnp B,pgi,rbf A and inf B showed a 2-20 fold upregulation.Statistically significant upregulation was obtained for all the above mentioned genes(P < 0.05).tlp C,cag A,vac A,sod B,rbf A,inf B,tnp B,lpx C and mur I were also significantly upregulated(P < 0.01).These data suggest a strong correlation between results obtained in vitro in the macrophage cell line and in the intact animal.CONCLUSION:The positive identification of these genes demonstrates that our IVET systems are powerful tools for studying H.pylori gene expression in the host environment. | Aparna Singh Nathaniel Hodgson Ming Yan Jungsoo Joo Lei Gu Hong Sang Emmalena Gregory-Bryson William G Wood Yisheng Ni Kimberly Smith Sharon H Jackson William G Coleman | 2012 | World Journal of Gastroenterology2012，18，32： | 5 |
| 9 | Differential mRNA expression profiling of oral squamous cell carcinoma by high-throughput RNA sequencing显示文摘Differentially expressed genes are thought to regulate the development and progression of oral squamous cell carcinomas(OSCC).The purpose of this study was to screen differentially expressed mRNAs in OSCC and matched paraneoplastic normal tissues,and to explore the intrinsic mechanism of OSCC development and progression.We obtained the differentially expressed mRNA expression profiles in 10 pairs of fresh-frozen OSCC tissue specimens and matched paraneoplastic normal tissue specimens by high-throughput RNA sequencing.By using Gene Ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analyses,the functional significance of the differentially expressed genes were analyzed.We identified 1,120 significantly up-regulated mRNAs and 178 significantly down-regulated mRNAs in OSCC,compared to normal tissue.The differentially expressed mRNAs were involved in 20 biological processes and 68 signal pathways.Compared to adjacent normal tissue,the expression of MAGEA11 was up-regulated;TCHH was down-regulated.These findings were verified by real-time PCR.These differentially expressed mRNAs may function as oncogenes or tumor suppressors in the development and progression of OSCC.This study provides novel insights into OSCC.However,further work is needed to determine if these differentially expressed mRNAs have potential roles as diagnostic biomarkers and candidate therapeutic targets for OSCC. | Liangyu Ge Siyu Liu Long Xie Lei Sang Changyan Ma Hongwei Li | 2015 | The Journal of Biomedical Research2015，29，5： | 4 |
| 10 | Study on Surface Adsorption and Inhibition Behavior of Corrosion Inhibitors Contained in Copper Foil Rolling Oil显示文摘Adsorption and inhibition behavior of 2,5-bis(ethyldisulfanyl)-1,3,4-thiadiazole(DMTDA) and N-((6-methyl-1H-benzo[d][1,2,3]triazol-1-yl)methyl)-N-octyloctan-1-amine(EAMBA) as corrosion inhibitors contained in copper foil rolling oil have been investigated using gravimetric and electrochemical techniques. Meanwhile, scanning electron microscopy(SEM) and energy dispersive spectrometer(EDS) have been employed to observe the surface topography and analyze the components on copper foil. The results show that the rolling oil containing DMTDA and EAMBA can significantly decrease the dissolution rate and increase the inhibition efficiency of samples, especially in the case of best compounded rolling oil system. The SEM and EDS investigations also confirmed that the protection of the copper foil surface is achieved by strong adsorption of the molecules which can prevent copper from being corroded easily. Reactivity descriptors of the corrosion inhibitors have been calculated by the density functional theory(DFT) and the reactivity has been analyzed through the molecular orbital and Fukui indices. Active sites of inhibitor are mainly concentrated on the ring and the polar functional groups, and in the meanwhile, the distribution is helpful to form coordination and backbonding among molecules and then to form stable adsorption on the metal surface. And this work provides theoretical evidence for the selection of corrosion inhibitors contained in copper foil rolling oil. | Xiong Sang Sun Jianlin Jiang Wei Xu Yang Zeng Yingfeng Xia Lei | 2015 | China Petroleum Processing & Petrochemical Technology2015，17，1： | 3 |

| 12 | Excellent light-capture capability of trilobal SiNW for ultra-high JSC in single-nanowire solar cells显示文摘Single-.nanowire solar cells with a unique light-concentration property are expected to exceed the Shockley-Queisser limit.The architecture of single nanowire is an important factor to regulate its optical performance.We designed a trilobal silicon nanowire(SiNW)with two cquivalent scales that possesses superior light-absorption efficiency in the whole wavelength range and shows good tolerance for incident angle.The electric field distribution in this geometry is concentrated in the blade with small equivalent scale and pivot with large equivalent scale,respectively,in the short wavelength range and long wavelength range.Corresponding good light absorption of trilobal SiNW in the two wavelength ranges leads to stronger total light absorption capacity than that of cylindrical SiNW.Trilobal single nanowire solar cells can obtain a short-circuit current density(JSC)of 647 mA·cm^2,which provides a new choice for designing single nanowire with excellent light-capture capability. | ZHONGLIANG GAO GUILU Lin YUPENG ZHENG NA SANG YINGFENG LI LEI CHEN MEICHENG LI | 2020 | Photonics Research2020，8，6： | 2 |
| 13 | Metathesis of 1-butene and 2-butene to propene over Re_2O_7 supported on macro-mesoporous γ-alumina prepared via a dual template method显示文摘Macro-mesoporous γ-alumina support(MMA) was prepared by a sol-gel route in aqueous medium using pseudo-boehmite as aluminum source and polystyrene microspheres and Pluronic P123 as hard and soft dual templates,respectively.MMA had a BET specific surface area of about 259 m2 g-1,total pore volume of about 1.61 cm3 g-1,macropore diameter of about 102 nm,and mesopore diameter of about 14 nm.Re2O7/MMA and conventional Re2O7/Al2O3 were prepared by a incipient-wetness impregnation method,and their catalytic performances in the metathesis of 1-butene and 2-butene were tested in a fixed-bed tubular reactor.The result showed that Re2O7/MMA possessed higher activity and far longer working life-span than conventional Re2O7/Al2O3. | Lei Sang Sheng-Li Chen Guimei Yuan Min Zheng Ju You Aicheng Chen Rui Li Lanjing Chen | 2012 | Journal of Natural Gas Chemistry2012，21，2： | 2 |
| 14 | Metastable Equilibrium in Quaternary System Li_2SO_4+K_2SO_4+Li_2CO_3+K_2CO_3+H_2O at 288 K显示文摘Metastable equilibrium solubilities and densities of the Li2SO4+K2SO4+Li2CO3+K2CO3+H2O system at 288 K were determined experimentally by using the isothermal evaporation method. According to the experimental data, the metastable equilibrium solubility phase diagram was constructed. In the phase diagram, there are three invariant points, seven univariant curves, and five fields of crystallization: Li2SO4·H2O, K2SO4, Li2CO3, K2CO3·3/2H2O and K2SO4·Li2SO4. The double salt K2SO4·Li2SO4 was found in the metastable equilibria. Lithium carbonate(Li2CO3) has the smallest solubility in the quaternary system. | SANG Shi-hua YIN Hui-an LEI Ning-fei | 2007 | Chemical Research in Chinese Universities2007，23，2： | 2 |
| 15 | Relationship between the Plasma Fibulin-1 Levels,Pulse Wave Velocity,and Vascular Age in Asymptomatic Hyperuricemia显示文摘Fibulin-1(FBLN-1),an elastin-associated extracellular matrix protein,has been found in blood and may play a role in the pathophysiological processes leading to cardiovascular disease(CVD).We aimed to investigate the relationship between fibulin-1 levels and the risk of CVD by evaluating vascular age derived from the Framingham Heart Study and brachial-ankle Pulse Wave Velocity(baPWV)in patients with asymptomatic hyperuricemia(AHU).In total,66 patients with AHU and 66 gender-and age-matched healthy individuals were enrolled.The plasma fibulin-1 levels were measured by immunochemistry.Patients with AHU presented significantly higher vascular age[median(interquartile range):54(22)vs.48(14)years,P=0.01]and baPWV[mean±SD:1373±223 vs.1291±177 cm/s,P=0.02]than the healthy subjects;however,no significant difference was observed in the plasma fibulin-1 level between the patients with AHU and healthy subjects[median(interquartile range):4018(3838)vs.3099(3405)ng/mL,P=0.31].A correlation between fibulin-1 levels and baPWV was observed only in patients with AHU(r=0.29,P=0.02);and there was also a suggestively statistically significant correlation between fibulin-1 levels and vascular age(r=0.22,P=0.08).However,these associations were rendered insignificant after adjustments for potential confounders.In healthy subjects,no correlation was observed between fibulin-1 levels and CVD risk.This study reveals that plasma fibulin-1 levels may reflect the CVD risk in patients with AHU,but the relationship is not robust. | Yu SANG Kai-min MAO Yi HUANG Xiao-fen WU Xing-fen WANG Lei RUAN Cun-tai ZHANG | 2021 | Current Medical Science2021，41，1： | 1 |

| 18 | Influence of catalyst support structure on ethene/decene metathesis and coke formation over WO_3/SiO_2 catalyst显示文摘8wt%WO3/SiO2 metathesis (disproportionation) catalysts with different pore structures were prepared by the incipient-wetness-impregnation method. The as-synthesized catalysts were characterized by N2 adsorption-desorption, scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-visible diffuse reflectance spectroscopy (DRS) and scanning transmission electron microscopy-high-angle annular dark field (STEM HAADF). The results of STEM HAADF showed that WO3 species were not uniformly distributed on the SiO2 support. The experimental results of 8wt%WO3/SiO2 performance in ethene/decene metathesis revealed that the catalytic effect of 8wt%WO3/SiO2 catalyst and coke formation over it were closely related to the support pore structure: The 8wt%WO3/SiO2 catalyst with a more complicated pore structure showed better catalytic performance but the coke deposition rate was also faster. | Zheng Min Chen Sheng-Li Zhang Jun-Hui Liu Yan Sang Lei You Ju Wang Xiao-Dong | 2013 | Petroleum Science2013，10，1： | 1 |
| 19 | Preparation of mesoporous alumina with large pore size and their supported rhenium oxide catalysts in metathesis of 1-butene and 2-butene to propene显示文摘Mesoporous γ-aluminas with large pore size(up to 19 nm,denoted as MA19) are prepared from dispersed pseudo-boehmite using pluronic P123 as template.It is found that these mesoporous alumina supported rhenium oxide catalysts were more active and have far longer working life-span in gas-phase metathesis of 1-butene and 2-butene to propene than rhenium oxide on conventional alumina with small pore size(5 nm).At 60°C and atmospheric pressure with WHSV = 1 h-1,the similar stable conversions of butene(ca.55%) for all the 13 wt% Re 2 O 7 /alumina catalysts were obtained near the chemical equilibrium,and the stable working life-spans of Re 2 O 7 /MA19 were far longer than that of Re 2 O 7 /Al 2 O 3,being about 70 h and 20 h,respectively. | Lei Sang Sheng-Li Chen Guimei Yuan Zheng Zhou Rui Li Aicheng Chen Min Zheng Ju You | 2012 | Journal of Natural Gas Chemistry2012，21，3： | 1 |
| 20 | Effect of moxibustion on autophagy and the inflammatory response of synovial cells in rheumatoid arthritis model rats显示文摘OBJECTIVE:To investigate the effect of moxibustion on synovitis and the autophagy of synoviocytes in rheumatoid arthritis(RA).METHODS:Forty Sprague-Dawley rats were randomly divided into a normal group,model group,moxibustion group,cigarette moxibustion group,and medicine group,with eight rats included in each group.The RA model was established by subcutaneous injection of complete Freund's adjuvant into the left posterior toe.Rats in the model group were not interfered with.In the moxibustion group,rats were treated by moxibustion,where a 1-cm diameter moxa stick was applied at the left Zusanli(ST 36)point.The distance of the moxa stick to the skin was 2 cm and moxibustion was completed for 20 min daily for 15 d total.In the cigarette moxibustion group,the moxa stick was replaced by a common cigarette.In the medicine group,rats were treated with a tripterygium glycoside suspension(8 mg/kg)once a day for 15 d total.In each group,the left hind limb toe volume was measured with a toe volume meter;the synovial cells were observed by hematoxylin and eosin staining;the interleukin(IL)-4,IL-6,IL-10,IL-1β,IL-23,IL-17,and tumor necrosis factor(TNF)-αlevels in serum were measured by enzyme-linked immunosorbent assay;the erythrocyte sedimentation rate(ESR)were detected by Westergren sedimentation rate testing;the C-reactive protein(CRP)and rheumatoid factor(RF)levels in serum were detected by rate nephelometry;the expression levels of ULK1,autophagy-associated protein(Atg)3,Atg5,and Atg12 messenger RNA(m RNA)in synovium were detected by real time-quantitative polymerase chain reaction(RT-q PCR);and the protein expression levels of phosphatidylinositol-3-kinase(PI3K),protein kinase B(Akt),mammalian target of rapamycin(mTOR),LC3-Ⅱ,beclin-1,phosphorylated-PI3K(p-PI3K),p-Akt,p-mTOR in synovium were detected by Western blotting.RESULTS:Among the RA model rats,joint swelling,an inflammatory reaction,and the proliferation of synovial tissue were obvious and the signal of the PI3K/Akt/mTOR pathway was active,while autophagy was inhibited.Moxibustion at Zusanli(ST36)or intragastric administration of Tripterygium wilfordii glycosides could alleviate the inflammatory reaction of RA rats;relieve the swelling of the toes;downregulate the levels of ESR,CRF,RF;lower the levels of IL-6,IL-1β,TNF-α,and IL-17;and increase the IL-4 and IL-10.At the same time,the m RNA expression levels of ULK1,Atg3,Atg5,and Atg12 and those of LC3-Ⅱand beclin-1 were increased,while the PI3K,Akt,mTOR,p-PI3K,p-Akt,p-mTOR were decreased.Cigarette moxibustion did not significantly reduce the swelling of the toe joint in RA rats,and was not as good as that of moxibustion or Tripterygium wilfordii polyglycosides in the effects of inflammation relief and the influences of the levels of ESR,CRF,RF.While cigarette moxibustion has a weak effect to affect the expression of corresponding molecules in autophages and the expression level of the autophagy biomaker in synovial tissue.Moxibustion and tripterygium glycosides can significantly reduce the joint swelling,relieve synovitis and synovial hyperplasia,and inhibit the PI3K/Akt/mTOR signaling pathway to increase autophagy in a manner superior to cigarette moxibustion.CONCLUSION:Moxibustion can limit the proliferation of synoviocytes in RA rats by inhibiting the PI3K/Akt/mTOR signaling pathway,promoting autophagy,effectively reducing synovitis,and alleviating joint swelling. | HAO Feng WANG Qiang LIU Lei WU Libin CAI Ronglin SANG Jiajia HU Jun WANG Jie YU Qing HE Lu SHEN Yingchao MIAO Yiming HU Ling WU Zijian | 2022 | Journal of Traditional Chinese Medicine2022，42，1： | 1 |
