3Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development.Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding 2020Science China Chemistry2020,63,6:15
4Very 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
5Primary biliary cirrhosis degree assessment by acoustic radiation force impulse imaging and hepatic fibrosis indicators显示文摘AIM: To evaluate the assessment of primary biliary cirrhosis degree by acoustic radiation force impulse imaging(ARFI) and hepatic fibrosis indicators. METHODS: One hundred and twenty patients who developed liver cirrhosis secondary to primary biliary cirrhosis were selected as the observation group, with the degree of patient liver cirrhosis graded by Child-Pugh(CP) score. Sixty healthy individuals were selected as the control group. The four indicators of hepatic fibrosis were detected in all research objects, including hyaluronic acid(HA), laminin(LN), type Ⅲ collagen(PC Ⅲ), and type Ⅳ collagen(Ⅳ-C). The liver parenchyma hardness value(LS) was then measured by ARFI technique. LS and the four indicators of liver fibrosis(HA, LN, PC Ⅲ, and Ⅳ-C) were observed in different grade CP scores. The diagnostic value of LS and the four indicators of liver fibrosis in determining liver cirrhosis degree with PBC, whether used alone or in combination, were analyzed by receiver operating characteristic(ROC) curve.RESULTS: LS and the four indicators of liver fibrosis within the three classes(A, B, and C) of CP scores in the observation group were higher than in the control group, with C class > B class > A class; the differences were statistically significant(P < 0.01). Although AUC values of LS within the three classes of CP scores were higher than in the four indicators of liver fibrosis, sensitivity and specificity were unstable. The ROC curves of LS combined with the four indicators of liver fibrosis revealed that: AUC and sensitivity in all indicators combined in the A class of CP score were higher than in LS alone, albeit with slightly decreased specificity; AUC and specificity in all indicators combined in the B class of CP score were higher than in LS alone, with unchanged sensitivity; AUC values(0.967), sensitivity(97.4%), and specificity(90%) of all indicators combined in the C class of CP score were higher than in LS alone(0.936, 92.1%, 83.3%). CONCLUSION: The diagnostic value of PBC cirrhosis degree in liver cirrhosis degree assessment by ARFI combined with the four indicators of serum liver fibrosis is of satisfactory effectiveness and has important clinical application value.Hai-Chun Zhang Rong-Fei Hu Ting Zhu Ling Tong Qiu-Qin Zhang 2016World Journal of Gastroenterology2016,22,22:8

7Hepatocellular carcinoma: Can LI-RADS v2017 with gadoxetic-acid enhancement magnetic resonance and diffusion-weighted imaging improve diagnostic accuracy?显示文摘BACKGROUND The Liver Imaging Reporting and Data System(LI-RADS), supported by the American College of Radiology(ACR), has been developed for standardizing the acquisition, interpretation, reporting, and data collection of liver imaging examinations in patients at risk for hepatocellular carcinoma(HCC). Diffusionweighted imaging(DWI), which is described as an ancillary imaging feature of LI-RADS, can improve the diagnostic efficiency of LI-RADS v2017 with gadoxetic acid-enhanced magnetic resonance imaging(MRI) for HCC.AIM To determine whether the use of DWI can improve the diagnostic efficiency of LIRADS v2017 with gadoxetic acid-enhanced magnetic resonance MRI for HCC.METHODS In this institutional review board-approved study, 245 observations of high risk of HCC were retrospectively acquired from 203 patients who underwent gadoxetic acid-enhanced MRI from October 2013 to April 2018. Two readers independently measured the maximum diameter and recorded the presence of each lesion and assigned scores according to LI-RADS v2017. The test was used to determine the agreement between the two readers with or without DWI. In addition, the sensitivity(SE), specificity(SP), accuracy(AC), positive predictive value(PPV), and negative predictive value(NPV) of LI-RADS were calculated.Youden index values were used to compare the diagnostic performance of LIRADS with or without DWI.RESULTS Almost perfect interobserver agreement was obtained for the categorization of observations with LI-RADS(kappa value: 0.813 without DWI and 0.882 with DWI). For LR-5, the diagnostic SE, SP, and AC values were 61.2%, 92.5%, and71.4%, respectively, with or without DWI; for LR-4/5, they were 73.9%, 80%, and75.9% without DWI and 87.9%, 80%, and 85.3% with DWI; for LR-4/5/M, they were 75.8%, 58.8%, and 70.2% without DWI and 87.9%, 58.8%, and 78.4% with DWI; for LR-4/5/TIV, they were 75.8%, 75%, and 75.5% without DWI and 89.7%,75%, and 84.9% with DWI. The Youden index values of the LI-RADS classification without or with DWI were as follows: LR-4/5: 0.539 vs 0.679; LR-4/5/M: 0.346 vs 0.467; and LR-4/5/TIV: 0.508 vs 0.647.CONCLUSION LI-RADS v2017 has been successfully applied with gadoxetate-enhanced MRI for patients at high risk for HCC. The addition of DWI significantly increases the diagnostic efficiency for HCC.Tong Zhang Zi-Xing Huang Yi Wei Han-Yu Jiang Jie Chen Xi-Jiao Liu Li-Kun Cao Ting Duan Xiao-Peng He Chun-Chao Xia Bin Song 2019World Journal of Gastroenterology2019,25,5:6
8The Mechanism and Influence of AKAP12 in Different Cancers显示文摘The development of cancer is a complex process that requires the participation of many factors, including mutations in genes, regulation of signaling pathways, disruption of homeostasis, and failure of self-monitoring mechanisms. Sufficient evidence has shown that the A kinase anchoring protein (AKAP) family plays an important role in signal transduction in cancer. AKAP12 and AKAP12-regulated signaling pathways are critically involved in the development and progression of a variety of tumors.WU Xuan WU Tong LI Ke LI Yuan HU Ting Ting WANG Wei Feng QIANG Su Jing XUE Shao Bo LIU Wei Wei 2018Biomedical and Environmental Sciences2018,31,12:5
9A nanocleaner specifically penetrates the blood-brain barrier at lesions to clean toxic proteins and regulate inflammation in Alzheimer's disease显示文摘Insurmountable blood-brain barrier(BBB) and complex pathological features are the key factors affecting the treatment of Alzheimer's disease(AD).Poor accumulation of drugs in lesion sites and undesired effectiveness of simply reducing Aβ deposition or TAU protein need to be resolved urgently.Herein,a nanocleaner is designed with a rapamycin-loaded ROS-responsive PLGA core and surface modification with KLVFF peptide and acid-cleavable DAG peptide [R@(ox-PLGA)-KcD].DAG can enhance the targeting and internalization effect of nanocleaner towards neurovascular unit endothelial cells in AD lesions,and subsequently detach from nanocleaner in response to acidic microenvironment of endosomes to promote the transcytosis of nanocleaner from endothelial cells into brain parenchyma.Then exposed KLVFF can capture and carry Aβ to microglia,attenuating Aβ-induced neurotoxicity.Strikingly,rapamycin,an autophagy promoter,is rapidly liberated from nanocleaner in the high ROS level of lesions to improve Aβ degradation and normalize inflammatory condition.This design altogether accelerates Aβ degradation and alleviates oxidative stress and excessive inflammatory response.Collectively,our finding offers a strategy to target the AD lesions precisely and multi-pronged therapies for clearing the toxic proteins and modulating lesion microenvironment,to achieve efficient AD therapy.Ting Lei Zhihang Yang Xue Xia Yuxiu Chen Xiaotong Yang Rou Xie Fan Tong Xiaolin Wang Huile Gao 2021Acta Pharmaceutica Sinica B2021,11,12:4

12Efficacy of texture analysis of pre-operative magnetic resonance imaging in predicting microvascular invasion in hepatocellular carcinoma显示文摘BACKGROUND Presence of microvascular invasion(MVI)indicates poorer prognosis postcurative resection of hepatocellular carcinoma(HCC),with an increased chance of tumour recurrence.By present standards,MVI can only be diagnosed postoperatively on histopathology.Texture analysis potentially allows identification of patients who are considered‘high risk’through analysis of pre-operative magnetic resonance imaging(MRI)studies.This will allow for better patient selection,improved individualised therapy(such as extended surgical margins or adjuvant therapy)and pre-operative prognostication.AIM This study aims to evaluate the accuracy of texture analysis on pre-operative MRI in predicting MVI in HCC.METHODS Retrospective review of patients with new cases of HCC who underwent hepatectomy between 2007 and 2015 was performed.Exclusion criteria:No preoperative MRI,significant movement artefacts,loss-to-follow-up,ruptured HCCs,previous hepatectomy and adjuvant therapy.Fifty patients were divided into MVI(n=15)and non-MVI(n=35)groups based on tumour histology.Selected images of the tumour on post-contrast-enhanced T1-weighted MRI were analysed.Both qualitative(performed by radiologists)and quantitative data(performed by software)were obtained.Radiomics texture parameters were extracted based on the largest cross-sectional area of each tumor and analysed using MaZda software.Five separate methods were performed.Methods 1,2 and 3 exclusively made use of features derived from arterial,portovenous and equilibrium phases respectively.Methods 4 and 5 made use of the comparatively significant features to attain optimal performance.RESULTS Method 5 achieved the highest accuracy of 87.8%with sensitivity of 73%and specificity of 94%.CONCLUSION Texture analysis of tumours on pre-operative MRI can predict presence of MVI in HCC with accuracies of up to 87.8%and can potentially impact clinical management.Jordan Zheng Ting Sim Terrence Chi Hong Hui Tong Kuan Chuah Hsien Min Low Cher Heng Tan Vishal GShelat 2022World Journal of Clinical Oncology2022,13,11:3
13Sliding mode control design for oblique wing aircraft in wing skewing process显示文摘When the wing of Oblique Wing Aircraft(OWA) is skewed, the center of gravity, inertia and aerodynamic characteristics of the aircraft all significantly change, causing an undesirable flight dynamic response, affecting the flying qualities, and even endangering the flight safety. In this study,the dynamic response of an OWA in the wing skewing process is simulated, showing that the threeaxis movements of the OWA are highly coupled and present nonlinear characteristics during the wing skewing. As the roll control efficiency of the aileron decreases due to the shortened control arm in an oblique configuration, the all-moving horizontal tail is used for additional roll and the control allocation is performed based on minimum control energy. Given the properties of pitchroll-yaw coupling and control input and state coupling, and the difficulty of establishing an accurate aerodynamic model in the wing skewing process due to unsteady aerodynamic force, a multi-loop sliding mode controller is formulated by the time-scale separation method. The closed-loop simulation results show that the asymmetric aerodynamics can be balanced and that the velocity and altitude of the aircraft maintain stable, which means that a smooth transition is obtained during the OWA's wing skewing.Ting YUE Zijian XU Lixin WANG Tong WANG 2019Chinese Journal of Aeronautics2019,32,2:2
14The chromosome-level Stevia genome provides insights into steviol glycoside biosynthesis显示文摘Stevia(Stevia rebaudiana Bertoni)is well known for its very sweet steviol glycosides(SGs)consisting of a common tetracyclic diterpenoid steviol backbone and a variable glycone.Steviol glycosides are 150–300 times sweeter than sucrose and are used as natural zero-calorie sweeteners.However,the most promising compounds are biosynthesized in small amounts.Based on Illumina,PacBio,and Hi-C sequencing,we constructed a chromosome-level assembly of Stevia covering 1416 Mb with a contig N50 value of 616.85 kb and a scaffold N50 value of 106.55 Mb.More than four-fifths of the Stevia genome consisted of repetitive elements.We annotated 44,143 high-confidence protein-coding genes in the high-quality genome.Genome evolution analysis suggested that Stevia and sunflower diverged~29.4 million years ago(Mya),shortly after the whole-genome duplication(WGD)event(WGD-2,~32.1 Mya)that occurred in their common ancestor.Comparative genomic analysis revealed that the expanded genes in Stevia were mainly enriched for biosynthesis of specialized metabolites,especially biosynthesis of terpenoid backbones,and for further oxidation and glycosylation of these compounds.We further identified all candidate genes involved in SG biosynthesis.Collectively,our current findings on the Stevia reference genome will be very helpful for dissecting the evolutionary history of Stevia and for discovering novel genes contributing to SG biosynthesis and other important agronomic traits in future breeding programs.Xiaoyang Xu Haiyan Yuan Xiaqing Yu Suzhen Huang Yuming Sun Ting Zhang Qingquan Liu Haiying Tong Yongxia Zhang Yinjie Wang Chunxiao Liu Lei Wu Menglan Hou Yongheng Yang 2021Horticulture Research2021,8,1:2
152021 Chinese consensus on the diagnosis and management of primary immune thrombocytopenia in pregnancy显示文摘Immune thrombocytopenia(ITP)is an acquired disease characterized by isolated thrombocytopenia,which is one of the most common causes of thrombocytopenia during pregnancy.Women with ITP who have severe thrombocytopenia are at an increased risk for life-threatening obstetric complications.Therefore,we established this consensus statement on the diagnosis and management of ITP during pregnancy(detailed information is available in the Supplementary File,http://gffzz16e312a87a7141a5hp5cxqpvk0uqc69vp.ffgz.tsg.suse.edu.cn/A978).Zhang Xiaohui Chen Fangping Chen Xiequn Cheng Yunfeng Fang Meiyun Feng Jianming Fu Haixia Gao Hong Han Yue He Aili Hou Ming Hu Yu Huang Ruibin Huang Wenrong Jing Zhicheng Kong Peiyan Liang Aibin Liang Meiying Liu Daihong Liu Junling Liu Lin Liu Xiaowei Ma Liangming Mei Heng Ni Heyu Niu Ting Peng Jun Qiao Jianlin Ren Jinhai Song Yongping Tang Liang V Tong Tong Wang Shaoyuan Wang Xin Wang Zhao Wei Hui Wu Depei Wu Guangsheng Xu Caigang Xu Xue Xu Yajing Yang Linhua Yang Renchi Yang Tonghua Yin Chenghong Yu Li Zhang Guangsen Zhang Lei Zhang Liansheng Zhang Xi Zhao Weili Zhao Yongqiang Zhou Daobin Zhou Hu Zhou Zeping Zhu Tienan Wang Jianliu Huang Xiaojun 2022Chinese Medical Journal2022,,8:2
16Triassic integrative stratigraphy and timescale of China显示文摘The Triassic rocks are widespread in China, and both marine and terrestrial strata are well developed. The Triassic stratigraphic architecture of China is very complex in both spatial variation of the so-called 'South Marine and North Continental', i.e. the southern areas of China occupied mostly by marine facies while the northern China by terrestrial facies during the Triassic Period, and temporal transition of the 'Lower Marine and Upper Continental', i.e. the lower part of the Triassic System composed mainly of marine facies and the upper part of terrestrial strata especially in South China. Although the Global Stratotype Section and Point(GSSP) of the Permian-Triassic boundary is located in South China, the Triassic of China except for some marine Lower-Middle Triassic depositions shows significantly local characteristics and is hardly correlated with the global chronostratigraphic chart. Consequently, the Triassic of China contains not only the international research hotspots but also difficult points in stratigraphic study. This paper aims to present a brief review of the Triassic in China, including chronostratigraphy, biostratigraphy, magnetostratigraphy and chemostratigraphy, and summarize an integrated Triassic stratigraphic framework of China. Accordingly, a stratigraphic correlation is proposed for the lithostratigraphic sequences among the three tectono-paleogeographic stratigraphic regions. The comprehensive study indicates that ammonoids are the classic index fossils in Triassic biostratigraphy but conodonts are more advantageous in the study and definition of the Triassic chronostratigraphic boundaries. China still has the potential to optimize the GSSPs of the Induan-Olenekian boundary and Olenekian-Anisian boundary. The correlation of the Permian-Triassic boundary between marine and terrestrial facies might be achieved with the help of the Permian-Triassic 'transitional bed' and its related biotic and environmental events in association with the biostratigraphic study of conchostracan, vertebrate and plant fossils. In addition, the carbon isotopes have been proved to be one of the powerful methods in marine Triassic stratigraphic study, whereas the oxygen and strontium isotopes may be additional important bridges to establish the correlation between the marine and terrestrial strata, but as yet lacking of relevant studies in terrestrial strata. Considering the most stratigraphic intervals of the Triassic and the terrestrial Triassic in China are difficult to be correlated to the global chart, the proposed Chinese(regional) Triassic chronostratigraphic chart of marine and terrestrial stages would be of importance to the study of Chinese Triassic stratigraphy and related aspects, but the stages must be conceptually in line with international standards and studied as soon as possible in order to finalize the definition.Jinnan TONG Daoliang CHU Lei LIANG Wenchao SHU Haijun SONG Ting SONG Huyue SONG Yuyang WU 2019Science China Earth Sciences2019,62,1:2
17Recovery of a Far-Eastern Strain of Tick-Borne Encephalitis Virus with a Full-Length Infectious cDNA Clone显示文摘Tick-borne encephalitis virus(TBEV) is a pathogenic virus known to cause central nervous system(CNS) diseases in humans, and has become an increasing public health threat nowadays. The rates of TBEV infection in the endemic countries are increasing. However, there is no effective antiviral against the disease. This underscores the urgent need for tools to study the emergence and pathogenesis of TBEV and to accelerate the development of vaccines and antivirals. In this study, we reported an infectious c DNA clone of TBEV that was isolated in China(the WH2012 strain). A beta-globin intron was inserted in the coding region of nonstructural protein 1(NS1) gene to improve the stability of viral genome in bacteria. In mammalian cells, the inserted intron was excised and spliced precisely, which did not lead to the generation of inserted mutants. High titers of infectious progeny viruses were generated after the transfection of the infectious clone. The cDNA-derived TBEV replicated efficiently, and caused typical cytopathic effect(CPE) and plaques in BHK-21 cells. In addition, the CPE and growth curve of cDNA-derived virus were similar to that of its parental isolate in cells. Together, we have constructed the first infectious TBEV cDNA clone in China, and the clone can be used to investigate the genetic determinants of TBEV virulence and disease pathogenesis, and to develop countermeasures against the virus.Penghui Li Chen Yao Ting Wang Tong Wu Wenfu Yi Yue Zheng Yuanjiu Miao Jianhong Sun Zhongyuan Tan Yan Liu Xiaowei Zhang Hanzhong Wang Zhenhua Zheng 2021Virologica Sinica2021,36,6:2
18SLC1A1-mediated cellular and mitochondrial influx of R-2-hydroxyglutarate in vascular endothelial cells promotes tumor angiogenesis in IDH1-mutant solid tumors显示文摘Muta nt isocitrate dehydrog en ase 1(mlDH1)drives tumorigenesis via produci ng on cometabolite R-2-hydroxyglutarate(R-2-HG)across various tumor types.However,mlDHl in hibitors appear only effective in hematological tumors.The therapeutic ben efit in solid tumors remains elusive,likely due to the complex tumor microenvironment.In this study,we discover that R-2-HG produced by IDH1-mutant tumor cells is preferentially imported into vascular endothelial cells and remodels mitochondrial respiration to promote tumor angiogenesis,conferring a therapeutic vulnerability in IDH1-mutant solid tumors.Mechanistically,SLC1 Alz a Na'-depe ndent glutamate tran sporter that is prefere ntially expressed in en dothelial cells,facilitates the in flux of R-2-HG from the tumor microenvironment into the endothelial cells as well as the intracellular trafficking of R-2-HG from cytoplasm to mitochondria.R-2-HG hijacks SLC1A1 to promote mitochondrial Na^(+)/Ca^(2+)exchange,which activates the mitochondrial respiratory chain and fuels vascular en dothelial cell migratio n in tumor an giogenesis.SLC1A1 deficiency in mice abolishes mlDHl-promoted tumor an giogenesis as well as the therapeutic benefit of mlDHl in hibitor in solid tumors.Moreover,we report that HH2301,a newly discovered mlDHl inhibitor,shows promising efficacy in treating IDH1-mutant cholangiocarcinoma in preclinical models.Together,we identify a new role of SLC1A1 as a gatekeeper of R-2-HG-mediated crosstalk between IDH1-mutant tumor cells and vascular en dothelial cells,and dem on strate the therapeutic potential of mlDHl in hibitors in treating IDH1-muta nt solid tumors via disrupting R-2-HG-promoted tumor angiogenesis.Xiaomin Wang Ziqi Chen Jun Xu Shuai Tang Nan An Lei Jiang Yixiang Zhang Shaoying Zhang Qingli Zhang Yanyan Shen Shijie Chen Xiaojing Lan Ting Wang Linhui Zhai Siyuwei Cao Siqi Guo Yingluo Liu Aiwei Bi Yuehong Chen Xiameng Gai Yichen Duan Ying Zheng Yixian Fu Yize Li Liang Yuan Linjiang Tong Kun Mo Mingcheng Wang Shu-Hai Lin Minjia Tan Cheng Luo Yi Chen Jia Liu Qiansen Zhang Leping Li Min Huang 2022Cell Research2022,32,7:2
