1Stenting for symptomatic intracranial arterial stenosis in China:1-year outcome of a multicentre registry study显示文摘background and purpose A multicentre prospective registry study of individually tailored stenting for a patient with symptomatic intracranial atherosclerotic stenosis(ICAS)combined with poor collaterals in China showed that the short-term safety and efficacy of stenting was acceptable.However,it remained uncertain whether the low event rate could be of a long term.We reported the 1-year outcome of this registry study to evaluate the long-term efficacy of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Methods Patients with symptomatic ICAS caused by 70%-99% stenosis located at the intracranial internal carotid,middle cerebral,intracranial vertebral or basilar arteries combined with poor collaterals were enrolled.Balloon-mounted stent or balloon plus self-expanding stent were selected based on the ease of vascular access and lesion morphology determined by the operators.The primary outcome was the rate of 30-day stroke,transient ischaemic attack and death,and 12-month ischaemic stroke within the same vascular territory,haemorrhagic stroke and vascular death after stenting.results From September 2013 to January 2015,300 patients(ages 58.3±9.78 years)were recruited.Among them,159 patients were treated with balloon-mounted stent and 141 with balloon plus self-expanding stent.During the 1-year follow-up,25 patients had a primary end point event.The probability of primary outcome at 1 year was 8.1%(95% CI 5.3% to 11.7%).In 76 patients with digital subtraction angiography follow-up,27.6%(21/76)had re-stenosis≥50% and 18.4%(14/76)had re-stenosis≥70%.No baseline characteristic was associated with the primary outcome.Conclusion The event rate remains low over 1 year of individually tailored stenting for patients with severe symptomatic ICAS combined with poor collaterals.Further randomised trial of comparing individually tailored stenting with best medical therapy is needed.Ning Ma Yong Zhang Jie Shuai Changchun Jiang Qiyi Zhu Kangning Chen Li Liu Baomin Li Xiangqun Shi Lianbo Gao Yajie Liu Feng Wang Yongli Li Tieyan Liu Hongbo Zheng Dapeng Mo Feng Gao Yilong Wang Yongjun Wang Lei Feng Zhongrong Miao 2018Stroke & Vascular Neurology2018,3,3:29
2Current technology development for CO2 utilization into solar fuels and chemicals:A review显示文摘The continuous consumption of fossil fuels causes two important impediments including emission of large concentrations of CO2 resulting in global warming and alarming utilization of energy assets.The conversion of greenhouse gas CO2 into solar fuels can be an expedient accomplishment for the solution of both problems,all together.CO2 reutilization into valuable fuels and chemicals is a great challenge of the current century.Owing to limitations in traditional approaches,there have been developed many novel technologies such as photochemical,biochemical,electrochemical,plasma-chemical and solar thermochemical.They are currently being used for CO2 capture,sequestration,and utilization to transform CO2 into valuable products such as syngas,methane,methanol,formic acid,as well as fossil fuel consumption reduction.This review summarizes different traditional and novel thermal technologies used in CO2 conversion with detailed information about their working principle,types,currently adopted methods,developments,conversion rates,products formed,catalysts and operating conditions.Moreover,a comparison of these novel technologies in terms of distinctive key features such as conversion rate,yield,use of earth metals,renewable energy,investment,and operating cost has been provided in order to have a useful review for future research direction.Azeem Mustafa Bachirou Guene Lougou Yong Shuai Zhijiang Wang Heping Tan 2020Journal of Energy Chemistry2020,29,10:16
3Study on gob-side entry retaining in fully-mechanized longwall with top-coal caving and its application显示文摘Based on the engineering background of gob-side entry retaining in fully-mechanized longwall with top coal caving(GER-FLTC) on N2105 working face of Yuwu coal mine, by adopting the methods of theoretical analysis and numerical calculation, the control techniques of surrounding rocks in GER-FLTC working face are studied in this paper. The two main difficulties of stability of surrounding rocks at gob-side retained entry in fully-mechanized longwall working face are the stability control of top coal and control of large deformation of GER-FLTC working face. Interaction mechanical model between roofing and roadside backfilling in GER-FLTC is established and the equations for the calculation of roof-cutting resistance of roadside backfilling are derived. Results of numerical calculation show that the damage zones of top coal can be categorized into the delaminating zone of top coal above the backfilling, tensile damage zone of top coal above the retained roadway and shear damage zone of the upper rib of the solid coal. Stability control of top coal is the critical part to success of GER-FLTC. With consideration of large deformation of surrounding rocks of gob-side retained entry in fully-mechanized longwall, the support technique of‘‘roofing control and wall strengthening'' is proposed where high strength and highly prestressed anchor rods and diagonal tensile anchor cables support are used for top coal, high strength and highly prestressed yielding anchor rod support is used for solid coal and roadside prestressed load-carrying backfilling is constructed by high-water material, in order to maintain the integrity of the top coal, transfer load, high resistance yielding load-carrying of solid coal, roof-cutting of roadside backfilling and support,and to achieve GER-FLTC. Results from this study are successfully applied in engineering practice.Su Hai Bai Jianbiao Yan Shuai Chen Yong Zhang Zizheng 2015International Journal of Mining Science and Technology2015,25,3:12
4Deep learning applied to two-dimensional color Doppler flow imaging ultrasound images significantly improves diagnostic performance in the classification of breast masses:a multicenter study显示文摘Background:The current deep learning diagnosis of breast masses is mainly reflected by the diagnosis of benign and malignant lesions.In China,breast masses are divided into four categories according to the treatment method:inflammatory masses,adenosis,benign tumors,and malignant tumors.These categorizations are important for guiding clinical treatment.In this study,we aimed to develop a convolutional neural network(CNN)for classification of these four breast mass types using ultrasound(US)images.Methods:Taking breast biopsy or pathological examinations as the reference standard,CNNs were used to establish models for the four-way classification of 3623 breast cancer patients from 13 centers.The patients were randomly divided into training and test groups(n=1810 vs.n=1813).Separate models were created for two-dimensional(2D)images only,2D and color Doppler flow imaging(2D-CDFI),and 2D-CDFI and pulsed wave Doppler(2D-CDFI-PW)images.The performance of these three models was compared using sensitivity,specificity,area under receiver operating characteristic curve(AUC),positive(PPV)and negative predictive values(NPV),positive(LR+)and negative likelihood ratios(LR-),and the performance of the 2D model was further compared between masses of different sizes with above statistical indicators,between images from different hospitals with AUC,and with the performance of 37 radiologists.Results:The accuracies of the 2D,2D-CDFI,and 2D-CDFI-PW models on the test set were 87.9%,89.2%,and 88.7%,respectively.The AUCs for classification of benign tumors,malignant tumors,inflammatory masses,and adenosis were 0.90,0.91,0.90,and 0.89,respectively(95%confidence intervals[CIs],0.87-0.91,0.89-0.92,0.87-0.91,and 0.86-0.90).The 2D-CDFI model showed better accuracy(89.2%)on the test set than the 2D(87.9%)and 2D-CDFI-PW(88.7%)models.The 2D model showed accuracy of 81.7%on breast masses≤1 cm and 82.3%on breast masses>1 cm;there was a significant difference between the two groups(P<0.001).The accuracy of the CNN classifications for the test set(89.2%)was significantly higher than that of all the radiologists(30%).Conclusions:The CNN may have high accuracy for classification of US images of breast masses and perform significantly better than human radiologists.Trial registration:Chictr.org,ChiCTR1900021375;http://www.chictr.org.cn/showproj.aspx?proj=33139.Teng-Fei Yu Wen He Cong-Gui Gan Ming-Chang Zhao Qiang Zhu Wei Zhang Hui Wang Yu-Kun Luo Fang Nie Li-Jun Yuan Yong Wang Yan-Li Guo Jian-Jun Yuan Li-Tao Ruan Yi-Cheng Wang Rui-Fang Zhang Hong-Xia Zhang Bin Ning Hai-Man Song Shuai Zheng Yi Li Yang Guang 2021Chinese Medical Journal2021,,4:11
5First mass measurement of short-lived nuclides at HIRFL-CSR显示文摘Recent commissioning of the HIRFL-CSR has demonstrated its ability to perform direct mass measurement for short-lived nuclides. Projectile fragments produced by the 78Kr ions at 481.88 MeV/u were separated with the new radioactive beam line in Lanzhou (RIBLL2), and injected into and stored in the experimental storage ring (CSRe). By operating the CSRe as an isochronous mass spectrometry, a typical mass resolution around 2.0×10?5 has been achieved. The masses for 63Ge, 65As and 67Se were measured for the first time. The measured masses are compared with theoretical predictions and the location of the proton drip-line for As isotopes is discussed. The implication of the 65As mass in the astrophysical rapid proton capture process has also been addressed.XU HuShan TU XiaoLin YUAN YouJin XIA JiaWen ZANG YongDong WANG Meng MAO RuiShi HU ZhengGuo MEI Bo SHUAI Peng ZHU ZhiChao TANG ShuWen GENG Peng LIU Yong ZHAO TieCheng ZHANG XueYing YANG JianCheng MAO LiJun ZHANG YuHu ZHOU XiaoHong HUANG WenXue XIAO GuoQing ZHAO HongWei ZHAN WenLong 2009Chinese Science Bulletin2009,54,24:11
6Very high baseline HIV viremia impairs efficacy of non-nucleoside reverse transcriptase inhibitor-based ART:a longterm observation in treatment-naïve patients显示文摘Background:It is not completely clear whether a very high pre-therapy viral load(≥500000 copies/ml)can impair the virological response.The aim of this study was to examine the influence of very high baseline HIV-RNA levels on long-term virological responses under one type of regimen.Methods:A retrospective study was performed based on data from two multicenter cohorts in China from January to November 2009,and from May 2013 to December 2015.Untreated HIV infected adults between 18 and 65 years old were recruited before receiving non-nucleoside reverse transcriptase inhibitor-based regimen.All patients had baseline HIV-RNA levels over 500 copies/ml,good adherence,and were followed for at least 24 weeks.Virological suppression was defined as the first HIV-RNA<50 copies/ml.Virological failure was defined as any of incomplete viral suppression(HIV-RNA≥200 copies/ml without virological suppression within 24 weeks of treatment)and viral rebound(confirmed HIV-RNA level≥50 copies/ml after virological suppression).Chi-square test,Kaplan–Meier analysis,Cox proportional hazards model and Logistic regression were used to compare virological response between each pretreated viral load stratum.Results:A total of 758 treatment-naïve HIV patients in China were enlisted.Median follow-up time(IQR)was 144(108–276)weeks.By week 48,rates of virological suppression in three groups(<100000,100000–500000 and≥500000 copies/ml)were 94.1,85.0,and 63.8%,respectively(P<0.001).Very high baseline HIV viremia over 500000 copies/ml were found to be associated with delayed virological suppression(≥500000 vs<100000,adjusted relative hazard=0.455,95%CI:0.32–0.65;P<0.001)as well as incomplete viral suppression(≥500000 vs<100000,adjusted odds ratio[aOR]=6.084,95%CI:2.761–13.407;P<0.001)and viral rebound(≥50000 vs<100000,aOR=3.671,95%CI:1.009–13.355,P=0.048).Conclusions:Very high levels of pre-treatment HIV-RNA were related with delayed efficacy of NNRTI-based ART and increased risk of treatment failure.More potent initial regimens should be considered for those with this clinical character.Shuai Chen Yang Han Xiao-Jing Song Yan-ling Li Ting Zhu Hong-Zhou Lu Xiao-Ping Tang Tong Zhang Min Zhao Yun He Sheng-Hua He Min Wang Yong-Zhen Li Shao-Biao Huang Yong Li Jing Liu Wei Cao Tai-Sheng Li 2020Infectious Diseases of Poverty2020,9,3:10

8Development and industrial application of ultra-fast cooling technology显示文摘A new-generation TMCP(NG-TMCP) with ultra fast cooling(UFC) as core technique was suggested instead of the conventional TMCP in which some problems are to be solved.And the ultra fast cooling technology has been successfully applied to the plate rolling production in Shouqin Metal Materials Co.Ltd.Industrial trials are reported for the production of X70 pipeline steels(about 70000 t) under UFC conditions.Pipeline steels with reasonably good properties have been produced on an industrial scale.UFC can improve the temperature uniformity,the mechanical properties and the plate profile of X70 pipeline steel.The performance features of the trial plates can meet the standard of X70 pipeline steel.Spot test results have shown that the qualification rate of shape control,the performance and charpy impact properties for the trial plates are 95%,97% and 98%,respectively.The impact values of X70 pipeline steel at UFC mode exceed the standard requirements of X80 pipeline steel.The productivity is enhanced because cutting quantity of head and tail of the plate is reduced.The enhancement of control accuracy of the red back temperatures is favorable for industrial production of X70 pipeline steel.The reduced production of the steel-making has been industrially achieved,since a new composition was designed by reducing the vanadium content to less than 0.045 wt.%.TIAN Yong TANG Shuai WANG BingXing WANG ZhaoDong WANG GuoDong 2012Science China(Technological Sciences)2012,55,6:9
9Thyroid function reference ranges during pregnancy in a large Chinese population and comparison with current guidelines显示文摘Background: A correct thyroid function reference range is important for the accurate diagnosis of thyroid disease during pregnancy. However, there is no consensus on whether thyroid function reference ranges in Chinese population should follow the America Thyroid Association (ATA) guidelines. This study aimed to establish a thyroid function reference range more suited to the Chinese population by evaluating the current thyroid function reference range in pregnant Chinese women and comparing it to the ATA guidelines. Methods: A total of 52,027 pregnant women were enrolled from January 2013 to December 2016. Thyroid stimulating hormone (TSH), free thyroxine (FT4), and thyroid peroxidase antibody (TPOAb) levels were tested during the first and third trimesters of pregnancy. Reference ranges of TSH and FT4 were established from the 2.5th and 97.5th percentiles of the TPOAb-negative population of women. The Mann-Whitney U test was used to compare thyroid hormones between the TPOAb-positive and TPOAbnegative groups. Results: We obtained that the TSH reference ranges were 0.03 to 3.52 mU/L and 0.39 to 3.67 mU/L, and the FT4 reference ranges were 11.7 to 19.7 pmol/L and 9.1 to 14.4pmol/L, in the firstand third trimester, respectively. If we used the 2011 ATA criteria about 7.0% and 4.0% pregnant women would be over diagnosed in first and third trimester, respectively, compared with local population thyroid hormone reference. When we compared our local criteria with the new 2017 ATA criteria, about 1.2% and 0.8% pregnant women would have a missed diagnosis in first and third trimester, respectively. Conclusions: Based on our data, which is in line with the current ATA guidelines, a population-based thyroid function reference range would be the first choice for diagnosis of thyroid disease during pregnancy in China. In case such population-based thyroid function reference ranges are unavailable in the east of China, our reference ranges can be adopted, if the same assay is used.Xi Yang Yu Meng Yong Zhang Chen Zhang Fei Guo Shuai Yang Rong Ding Jian-Xia Fan 2019Chinese Medical Journal2019,,5:9
10^11C-PIBPET和^18F-FDGPET显像诊断阿尔茨海默病与遗忘型轻度认知损害的临床价值显示文摘目的应用11C-PIB PET和18F-FDG PET显像研究阿尔茨海默病和遗忘型轻度认知损害患者β-淀粉样蛋白(Aβ)沉积与葡萄糖代谢之间的关系,联合载脂蛋白E(ApoE)基因型进一步探讨遗忘型轻度认知损害与阿尔茨海默病的相关性。方法利用PET显像对阿尔茨海默病(14例)、遗忘型轻度认知损害(10例)和正常对照者(5例)脑组织Aβ沉积和葡萄糖代谢变化进行分析,采用聚合酶链反应-限制性片段长度多态性方法对ApoE基因型进行分析。结果阿尔茨海默病组患者11C-PIB标准化摄取比值在下顶叶、颞叶外侧、额叶、后扣带回皮质和楔前叶、枕叶和纹状体均高于正常对照组(P<0.05);遗忘型轻度认知损害组患者脑组织11C-PIB结合水平呈双峰形。11C-PIB+aMCI亚组与阿尔茨海默病组、11C-PIB-aMCI亚组与正常对照组之间11C-PIB标准化摄取比值差异均无统计学意义(P>0.05)。18F-FDG PET显像显示,3/5例11C-PIB+aMCI亚组患者双侧顶叶、颞叶和楔前叶代谢减低,其中2例ApoEε4等位基因携带者随访期间进展至阿尔茨海默病;3/5例11C-PIB-aMCI亚组患者双侧额叶和前扣带回代谢减低。结论11C-PIB PET显像是筛查具有阿尔茨海默病病理特点的遗忘型轻度认知损害患者的有效工具。具有阿尔茨海默病病理特征的遗忘型轻度认知损害患者可伴有顶叶、颞叶外侧皮质和楔前叶代谢减低,其中ApoEε4等位基因携带者更易进展至阿尔茨海默病痴呆。Shi Zhihong Wang Ying Liu Shuai Liu Shuling Z hou Yuying Wang Jinhuan Cai Li Gao Shuo Ji Yong 2014中国现代神经疾病杂志2014,14,3:8
11Epidemiological survey of echinococcosis in Tibet Autonomous Region of China显示文摘Background:The echinococcosis is prevalent in 10 provinces/autonomous region in western and northern China.Epidemiological survey of echinococcosis in China in 2012 showed the average prevalence of four counties in Tibet Autonomous Region(TAR)is 4.23%,much higher than the average prevalence in China(0.24%).It is important to understand the transmission risks and the prevalence of echinococcosis in human and animals in TAR.Methods:A stratified and proportionate sampling method was used to select samples in TAR.The selected residents were examined by B-ultrasonography diagnostic,and the faeces of dogs were tested for the canine coproantigen against Echinococcus spp.using enzyme-linked immunosorbent assay.The internal organs of slaughtered domestic animals were examined by visual examination and palpation.The awareness of the prevention and control of echinococcosis among of residents and students was investigated using questionnaire.All data were inputted using double entry in the Epi Info database,with error correction by double-entry comparison,the statistical analysis of all data was processed using SPSS 21.0,and the map was mapped using ArcGIS 10.1,the data was tested by Chi-square test and Cochran-Armitage trend test.Results:A total of 80384 people,7564 faeces of dogs,and 2103 internal organs of slaughtered domestic animals were examined.The prevalence of echinococcosis in humans in TAR was 1.66%,the positive rate in females(1.92%)was significantly higher than that in males(1.41%),(X2=30.31,P<0.01),the positive rate of echinococcosis was positively associated with age(X2trend=-423.95,P<0.01),and the occupational populations with high positive rates of echinococcosis were herdsmen(3.66%)and monks(3.48%).The average positive rate of Echinococcus coproantigen in TAR was 7.30%.The positive rate of echinococcosis in livestock for the whole region was 11.84%.The average awareness rate of echinococcosis across the region was 33.39%.Conclusions:A high prevalence of echinococcosis is found across the TAR,representing a very serious concern to human health.Efforts should be made to develop an action plan for echinococcosis prevention and control as soon as possible,so as to control the endemic of echinococcosis and reduce the medical burden on the population.Bin Li Gongsang Quzhen Chui-Zhao Xue Shuai Han Wei-Qi Chen Xin-Liu Yan Zhong-Jie Li MLinda Quick Yong Huang Ning Xiao Ying Wang Li-Ying Wang Gesang Zuoga Bianba Gangzhu Bing-Cheng Ma Gasong Xiao-Gang Wei Niji Can-Jun Zheng Wei-Ping Wu Xiao-Nong Zhou 2019Infectious Diseases of Poverty2019,8,2:8
12Joint method for reconstructing three-dimensional temperature of flame using Lucy-Richardson and nearest neighbor filtering using light-field imaging显示文摘The real-time measurement and reconstruction of three-dimensional temperature are essential when studying the combustion process inside a flame. In the proposed sectioned flame light field imaging model, flame sections are reconstructed based on the characteristics identified using the Lucy-Richardson or nearest neighbor filtering methods, or a joint method involving a combination of both, to improve on the accuracy of two-dimensional temperature reconstruction. Compared to the results of a previous work, the proposed method increases the resolution in the depth of field direction and the extraction of the flame temperature of all sections from the same height ensures the accuracy of the reconstructed temperature distribution across the cross-section of the flame. The relative error when compared to the actual flame is less than 10%. Thus, this approach allows the accurate estimation of the three-dimensional temperature distribution inside a flame, and enables the rapid and effective reconstruction of the three-dimensional temperature field.LI TianJiao YUAN Yuan SHUAI Yong TAN HePing 2019Science China(Technological Sciences)2019,62,7:7
13Control mechanism and technique of floor heave with reinforcing solid coal side and floor corner in gob-side coal entry retaining显示文摘Floor heave is the most common convergence in gob-side entry retaining.The paper analyzes the form,process and characteristics of gob-side entry retaining with the comprehensive methods of theoretical analysis,numerical simulation and the field trial.Research results present that bending and folding floor heave is the main factor in the stage of the first panel mining;squeezing and fluidity floor heave plays a great role in the stable stage of gob-side entry retaining;the combination of the former two factors affects mainly the stage of the second mining ahead;abutment pressure is a fundamental contribution to the serious floor heave of gob-side entry retaining,and sides corners of solid coal body are key part in the case of floor heave controlling of gob-side entry retaining.Floor heave of gob-side entry retaining can be significantly controlled by reinforcing sides and corners of solid coal body,and influence rules on the floor heave of gob side entry retaining of sides supporting strength and the bottom bolt orientation in solid coal side are obtained.Research results have been successfully applied in gob-side entry retaining of G20-F23070 face haulage roadway in #2 coal mine of Pingmei Group,and the field observation shows that the proposed technique is an effective way in controlling the floor heave of gob-side entry retaining.Chen Yong Bai Jianbiao Yan Shuai Xu Ying Wang Xiangyu Ma Shuqi 2012International Journal of Mining Science and Technology2012,22,6:6
14Catalytic conversion of lignocellulosic biomass into chemicals and fuels显示文摘In the search of alternative resources to make commodity chemicals and transportation fuels for a low carbon future,lignocellulosic biomass with over 180-billion-ton annual production rate has been identified as a promising feedstock.This review focuses on the state-of-the-art catalytic transformation of lignocellulosic biomass into value-added chemicals and fuels.Following a brief introduction on the structure,major resources and pretreatment methods of lignocellulosic biomass,the catalytic conversion of three main components,i.e.,cellulose,hemicellulose and lignin,into various compounds are comprehensively discussed.Either in separate steps or in one-pot,cellulose and hemicellulose are hydrolyzed into sugars and upgraded into oxygen-containing chemicals such as 5-HMF,furfural,polyols,and organic acids,or even nitrogen-containing chemicals such as amino acids.On the other hand,lignin is first depolymerized into phenols,catechols,guaiacols,aldehydes and ketones,and then further transformed into hydrocarbon fuels,bioplastic precursors and bioactive compounds.The review then introduces the transformations of whole biomass via catalytic gasification,catalytic pyrolysis,as well as emerging strategies.Finally,opportunities,challenges and prospective of woody biomass valorization are highlighted.Weiping Deng Yunchao Feng Jie Fu Haiwei Guo Yong Guo Buxing Han Zhicheng Jiang Lingzhao Kong Changzhi Li Haichao Liu Phuc T.T.Nguyen Puning Ren Feng Wang Shuai Wang Yanqin Wang Ye Wang Sie Shing Wong Kai Yan Ning Yan Xiaofei Yang Yuanbao Zhang Zhanrong Zhang Xianhai Zeng Hui Zhou 2023Green Energy & Environment2023,8,1:6
15Characterization of myelin oligodendrocyte glycoprotein (MOG)35–55- specific CD8^+ T cells in experimental autoimmune encephalomyelitis显示文摘Background:The pathogenesis of multiple sclerosis(MS)is mediated primarily by T cells,but most studies of MS and its animal model,experimental autoimmune encephalomyelitis(EAE),have focused on CD4^+ T cells.The aims of the current study were to determine the pathological interrelationship between CD4 and CD8 autoreactive T cells in MS/EAE.Methods:Female C57BL/6 mice(n=20)were induced by myelin oligodendrocyte glycoprotein(MOG)35-55 peptide.At 14 days after immunization,T cells were isolated from the spleen and purified as CD4^+ and CD8^+ T cells by using CD4 and CD8 isolation kits,and then the purity was determined by flow cytometric analysis.These cells were stimulated by MOG35–55 peptide and applied to proliferation assays.The interferon-gamma(IFN-γ)and interleukin(IL)-4 secretion of supernatant of cultured CD4^+ and CD8^+ T cells were measured by enzyme-linked immunosorbent assays(ELISA).For adoptive transfer,recipient mice were injected with MOG35–55-specific CD8^+ or CD4^+ T cells.EAE clinical course was measured by EAE score at 0–5 scale and spinal cord was examined by staining with hematoxylin and eosin and Luxol fast blue staining.Results:CD8^+ CD3^+ and CD4^+ CD3^+ cells were 86%and 94%pure of total CD3^+ cells after CD8/CD4 bead enrichment,respectively.These cells were stimulated by MOG35–55 peptide and applied to proliferation assays.Although the CD8^+ T cells had a generally lower response to MOG35–55 than CD4^+ T cells,the response of CD8^+ T cells was not always dependent on CD4.CD8^+ T cell secreted less IFN-γand IL-4 compared with CD4^+ T cells.EAE was induced in wildtype B6 na?ve mice by adoptive transfer of MOG35–55-specific T cells from B6 active-induced EAE(aEAE)mice.A similar EAE score and slight inflammation and demyelination were found in naive B6 mice after transferring of CD8^+ T cells from immunized B6 mice compared with transfer of CD4^+ T cells.Conclusion:Our data suggest that CD8^+ autoreactive T cells in EAE have a lower encephalitogenic function but are unique and independent on pathogenic of EAE rather than their CD4^+ counterparts.Yong Peng Fei-Zhou Zhu Zhi-Xing Chen Jian-Xiong Zhou Lu Gan Shan-Shan Yang Shuai Gao Qian-Qian Liu 2019Chinese Medical Journal2019,,24:5
16Efficacy and safety of Reduqing granules in the treatment of common cold with wind-heat syndrome: a randomized, double-blind, double-dummy, positive-controlled trial显示文摘OBJECTIVE:To assess the efficacy and safety of Reduqing granules in patients with common cold with wind-heat syndrome(CCWHS).METHODS:A randomized, double-blind, double-dummy, parallel, positive-controlled trial included 72 CCWHS patients was performed.The participants were randomly assigned to two groups,Reduqing(RDQ) group and Lianhuaqingwen(LHQW) group, in a 1∶1 ratio.Patients in RDQ group received Reduqing granules and dummy Lianhuaqingwen capsules three times a day and patients in LHQW group received Lianhuaqingwen capsules and dummy Reduqing granules three times daily.The duration of treatment and follow-up were four days.RESULTS:There were no statistically significant differences in total markedly effective rate and total effective rate between RDQ group and LHQW group after treatment.Traditional Chinese Medicine(TCM) symptom score was significantly reduced after treatment in RDQ group, as well as in LHQW group.However, the difference of change in TCM symptom score between two groups was not statistically significant(P > 0.05).There were no significant differences between two groups in the median time to fever relief [RDQ group(4 ± 8) h vs LHQW group(4 ± 5) h] or the median time to fever clearance(RDQ group 47 h vs LHQW 36 h).No serious adverse events were reported during the study.CONCLUSION:Compared with Lianhuaqingwen capsules, Reduqing granules achieved similar therapeutic effect in the treatment of CCWHS and no drug-related adverse events were reported during the study.Therefore, Reduqing granules might be effective and safe in the treatment of CCWHS.Ma Yanjiao Zhang Zhongyi Wei Lianbo He Shuai Deng Xun Ji Aimin Zhou Benjie Jiang Deqi Li Mingxing Wang Yong 2017Journal of Traditional Chinese Medicine2017,37,2:5
17The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5
18The landscape of aging显示文摘Aging is characterized by a progressive deterioration of physiological integrity,leading to impaired functional ability and ultimately increased susceptibility to death.It is a major risk factor for chronic human diseases,including cardiovascular disease,diabetes,neurological degeneration,and cancer.Therefore,the growing emphasis on “healthy aging” raises a series of important questions in life and social sciences.In recent years,there has been unprecedented progress in aging research,particularly the discovery that the rate of aging is at least partly controlled by evolutionarily conserved genetic pathways and biological processes.In an attempt to bring full-fledged understanding to both the aging process and age-associated diseases,we review the descriptive,conceptual,and interventive aspects of the landscape of aging composed of a number of layers at the cellular,tissue,organ,organ system,and organismal levels.Yusheng Cai Wei Song Jiaming Li Ying Jing Chuqian Liang Liyuan Zhang Xia Zhang Wenhui Zhang Beibei Liu Yongpan An Jingyi Li Baixue Tang Siyu Pei Xueying Wu Yuxuan Liu Cheng-Le Zhuang Yilin Ying Xuefeng Dou Yu Chen Fu-Hui Xiao Dingfeng Li Ruici Yang Ya Zhao Yang Wang Lihui Wang Yujing Li Shuai Ma Si Wang Xiaoyuan Song Jie Ren Liang Zhang Jun Wang Weiqi Zhang Zhengwei Xie Jing Qu Jianwei Wang Yichuan Xiao Ye Tian Gelin Wang Ping Hu Jing Ye Yu Sun Zhiyong Mao Qing-Peng Kong Qiang Liu Weiguo Zou Xiao-Li Tian Zhi-Xiong Xiao Yong Liu Jun-Ping Liu Moshi Song Jing-Dong J.Han Guang-Hui Liu 2022Science China(Life Sciences)2022,65,12:4
19Analysis of CO_2 utilization into synthesis gas based on solar thermochemical CH_4-reforming显示文摘In this study, the solar thermochemical reactor performance for CO_2 utilization into synthesis gas(H_2+ CO) based on CH_4 reforming process was investigated in the context of carbon capture and utilization(CCU) technologies. The P1 radiation heat transfer model is adopted to establish the heat and mass transfer model coupled with thermochemical reaction kinetics. The reactor thermal behavior with direct heat transfer between gaseous reactant and products evolution and the effects of different structural parameters were evaluated. It was found that the reactor has the potential to utilize by ~60% of CO_2 captured with 40% of CH_4 co-fed into syngas(72.9% of H_2 and 27.1% of CO) at 741.31 k W/mof incident radiation heat flux. However, the solar irradiance heat flux and temperature distribution were found to significantly affect the reactant species conversion efficiency and syngas production. The chemical reaction is mainly driven by the thermal energy and higher species conversion into syngas was observed when the temperature distribution at the inner cavity of the reactor was more uniform. Designed a solar thermochemical reactor able to volumetric store concentrated irradiance could highly improve CCU technologies for producing energy-rich chemicals. Besides, the mixture gas inlet velocity, operating pressure and CO_2/CH_4 feeding ratio were crucial to determining the efficiency of CO_2 utilization to solar fuels. Catalytic CO_2-reforming of CH_4 to chemical energy is a promising strategy for an efficient utilization of CO_2 as a renewable carbon source.Bachirou Guene Lougou Yong Shuai Gédéon Chaffa Huang Xing Heping Tan Huibin Du 2019Journal of Energy Chemistry2019,28,1:4
20Laparoscopic finding of a hepatic subcapsular spider-like telangiectasis sign in biliary atresia显示文摘AIM To assess the diagnostic value of a laparoscopic finding of a hepatic subcapsular spider-like telangiectasis(HSST) sign in biliary atresia.METHODS A retrospective study was conducted first and then a validation set was used to investigate the value of an HSST sign in predicting biliary atresia(BA). In the retrospective study, laparoscopic images of the liver surface were reviewed in 126 patients with infantile cholestasis(72 BA patients and 54 non-BA cholestasis patients) and a control group of 38 patients with nonhepatic conditions. Analysis was first made by two observers separately and finally, a consensus conclusion was achieved. Then, the diagnostic value of the HSST sign was validated in an independent cohort including 45 BA and 45 non-BA patients.RESULTS In the retrospective investigation, an amplified HSST sign was found in all BA patients, while we were unable to detect the HSST sign in 98.1% of the 54 non-BA patients. There was no HSST sign in any of the control subjects. In the first review, the sensitivity and specificity from one reviewer were 100% and 98.1%, respectively, and the results from the other reviewer were both 100%. The consensus sensitivity and specificity were 100% and 98.1%, respectively. The HSST sign was defined as being composed of several enlarged tortuous spider-like vascular plexuses with two to eight branches distributed on all over the liver surface, which presented as either a concentrated type or a dispersed type. In the independent validation group, the sensitivity, specificity, positive predictive value and negative predictive value of the HSST sign were 100%, 97.8%, 97.8% and 100%, respectively.CONCLUSION The HSST sign is characteristic in BA, and laparoscopic exploration for the HSST sign is valuable in the diagnosis of BA.Ying Zhou Meng Jiang Shao-Tao Tang Li Yang Xi Zhang De-Hua Yang Meng Xiong Shuai Li Guo-Qing Cao Yong Wang 2017World Journal of Gastroenterology2017,23,39:4
