| 1 | Anti-SARS-CoV-2 activities in vitro of Shuanghuanglian preparations and bioactive ingredients显示文摘Human infection with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)causes coronavirus disease 2019(COVID-19)and there is no cure currently.The 3CL protease(3CLpro)is a highly conserved protease which is indispensable for CoVs replication,and is a promising target for development of broad-spectrum antiviral drugs.In this study we investigated the anti-SARS-CoV-2 potential of Shuanghuanglian preparation,a Chinese traditional patent medicine with a long history for treating respiratory tract infection in China.We showed that either the oral liquid of Shuanghuanglian,the lyophilized powder of Shuanghuanglian for injection or their bioactive components dose-dependently inhibited SARS-CoV-23CLpro as well as the replication of SARS-CoV-2 in Vero E6 cells.Baicalin and baicalein,two ingredients of Shuanghuanglian,were characterized as the first noncovalent,nonpeptidomimetic inhibitors of SARS-CoV-23CLpro and exhibited potent antiviral activities in a cell-based system.Remarkably,the binding mode of baicalein with SARS-CoV-23CLpro determined by X-ray protein crystallography was distinctly different from those of known 3CLpro inhibitors.Baicalein was productively ensconced in the core of the substrate-binding pocket by interacting with two catalytic residues,the crucial S1/S2 subsites and the oxyanion loop,acting as a“shield”in front of the catalytic dyad to effectively prevent substrate access to the catalytic dyad within the active site.Overall,this study provides an example for exploring the in vitro potency of Chinese traditional patent medicines and effectively identifying bioactive ingredients toward a specific target,and gains evidence supporting the in vivo studies of Shuanghuanglian oral liquid as well as two natural products for COVID-19 treatment. | Hai-xia Su Sheng Yao Wen-feng Zhao Min-jun Li Jia Liu Wei-juan Shang Hang Xie Chang-qiang Ke Hang-chen Hu Mei-na Gao Kun-qian Yu Hong Liu Jing-shan Shen Wei Tang Lei-ke Zhang Geng-fu Xiao Li Ni Dao-wen Wang Jian-ping Zuo Hua-liang Jiang Fang Bai Yan Wu Yang Ye Ye-chun Xu | 2020 | Acta Pharmacologica Sinica2020,41,9: | 32 |

| 3 | Inflammatory Cytokines and Alzheimer's Disease: A Review from the Perspective of Genetic Polymorphisms显示文摘Neuroinflammatory processes are a central feature of Alzheimer's disease(AD) in which microglia are over-activated, resulting in the increased production of proinflammatory cytokines. Moreover, deficiencies in the antiinflammatory system may also contribute to neuroinflammation. Recently, advanced methods for the analysis of genetic polymorphisms have further supported the relationship between neuroinflammatory factors and AD risk because a series of polymorphisms in inflammation-related genes have been shown to be associated with AD. In this review, we summarize the polymorphisms of both pro- and anti-inflammatory cytokines related to AD, primarily interleukin-1(IL-1), IL-6, tumor necrosis factor alpha, IL-4, IL-10, and transforming growth factor beta, as well as their functional activity in AD pathology. Exploration of the relationship between inflammatory cytokine polymorphisms and AD risk may facilitate our understanding of AD pathogenesis and contribute to improved treatment strategies. | Fan Su Feng Bai Zhijun Zhang | 2016 | Neuroscience Bulletin2016,32,5: | 22 |

| 9 | Study 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 | 2015 | International Journal of Mining Science and Technology2015,25,3: | 12 |
| 10 | Humoral immune response to circulating SARS-CoV-2 variants elicited by inactivated and RBD-subunit vaccines显示文摘SARS-CoV-2 variants could induce immune escape by mutations on the receptor-binding domain(RBD)and N-terminal domain(NTD).Here we report the humoral immune response to circulating SARS-CoV-2 variants,such as 501Y.V2(B.1.351),of the plasma and neutralizing antibodies(NAbs)elicited by CoronaVac(inactivated vaccine),ZF2001(RBD-subunit vaccine)and natural infection.Among 86 potent NAbs identified by high-throughput single-cell VDJ sequencing of peripheral blood mononuclear cells from vaccinees and convalescents,near half anti-RBD NAbs showed major neutralization reductions against the K417N/E484K/N501Y mutation combination,with E484K being the dominant cause.VH3-53/VH3-66 recurrent antibodies respond differently to RBD variants,and K417N compromises the majority of neutralizing activity through reduced polar contacts with complementarity determining regions.In contrast,the 242–244 deletion(242–244Δ)would abolish most neutralization activity of anti-NTD NAbs by interrupting the conformation of NTD antigenic supersite,indicating a much less diversity of anti-NTD NAbs than anti-RBD NAbs.Plasma of convalescents and CoronaVac vaccinees displayed comparable neutralization reductions against pseudo-and authentic 501Y.V2 variants,mainly caused by E484K/N501Y and 242–244Δ,with the effects being additive.Importantly,RBD-subunit vaccinees exhibit markedly higher tolerance to 501Y.V2 than convalescents,since the elicited anti-RBD NAbs display a high diversity and are unaffected by NTD mutations.Moreover,an extended gap between the third and second doses of ZF2001 leads to better neutralizing activity and tolerance to 501Y.V2 than the standard three-dose administration.Together,these results suggest that the deployment of RBD-vaccines,through a third-dose boost,may be ideal for combating SARS-CoV-2 variants when necessary,especially for those carrying mutations that disrupt the NTD supersite. | Yunlong Cao Ayijiang Yisimayi Yali Bai Weijin Huang Xiaofeng Li Zhiying Zhang Tianjiao Yuan Ran An Jing Wang Tianhe Xiao Shuo Du Wenping Ma Liyang Song Yongzheng Li Xiang Li Weiliang Song Jiajing Wu Shuo Liu Xuemei Li Yonghong Zhang Bin Su Xianghua Guo Yangyang Wei Chuanping Gao Nana Zhang Yifei Zhang Yang Dou Xiaoyu Xu Rui Shi Bai Lu Ronghua Jin Yingmin Ma Chengfeng Qin Youchun Wang Yingmei Feng Junyu Xiao Xiaoliang Sunney Xie | 2021 | Cell Research2021,31,7: | 12 |
| 11 | Osteopontin knockdown suppresses the growth and angiogenesis of colon cancer cells显示文摘AIM:To investigate the effects of osteopontin(OPN)gene expression knockdown on colon cancer Lovo cells in vitro.METHODS:Four candidate small interfering RNA(siRNA)constructs targeting the OPN gene and a scrambled control sequence(NC-siRNA)were synthesized and inserted into a pGPU6/GFP/Neo expression vector.After confirmation by restriction enzyme digestion and DNA sequencing,the recombinant plasmids were subsequently transfected into a human colon cancer cell line(Lovo)using a liposome transfection method.Stably transfected cells were maintained with G418 selection and referred to as Lovo-OPN-1,-2,-3,-4,and Lovo-NC cells.Knockdown efficiency of each of the four siRNA constructs was determined by realtime reverse transcription polymerase chain reaction assays and western blotting,and the construct with the most effective silencing was used for subsequent experiments.Cell proliferation,adhesion,and Matrigel invasion assays were performed to analyze the effects of OPN knockdown in stably transfected Lovo cells.The levels of four angiogenic factors,namely vascular endothelial growth factor(VEGF),matrix metalloproteinase(MMP)-2,MMP-9 and urokinase plasminogen activator were detected by enzyme-linked immunosorbent assays(ELISA).RESULTS:Recombinant vectors containing OPNspecific and scrambled siRNA sequences were successfully constructed and stably transfected into Lovo cells.Compared with the control Lovo and Lovo-NC cells,the levels of OPN mRNA and protein expression in LovoOPN-1,-2,-3,and-4 were significantly reduced(all P<0.05),with the most efficient reduction observed in Lovo-OPN-4 cells(P<0.05).Relative to untransfected Lovo cells,OPN mRNA expression levels in Lovo-NC and Lovo-OPN-4 cells were 1.008±0.067 and 0.160±0.023,respectively.The relative OPN protein expression levels in Lovo,Lovo-NC,and Lovo-OPN-4 cells were 3.024±0.211,2.974±0.630,and 0.121±0.008,respectively.Moreover,transfection with the scrambled sequence had no effect on the expression of OPN.After24,48,72,and 96 h of cultivation,absorption values at 450 nm to assess proliferation of Lovo-OPN-4 cells were 0.210±0.017,0.247±0.024,0.314±0.037,and 0.359±0.043,respectively,which were significantly lower than those of Lovo(0.244±0.031,0.313±0.024,0.513±0.048 and 0.783±0.051)and LovoNC cells(0.241±0.029,0.309±0.022,0.563±0.023,and 0.735±0.067)(all P<0.05).The absorption values at 595 nm,which were measured in a cell adhesion assay,showed that adhesion of Lovo-OPN-4 cells(0.215±0.036)was significantly decreased compared to Lovo(0.490±0.037)and Lovo-NC cells(0.462±0.043)(P<0.05).The number of invasive Lovo-OPN-4 cells(16.1±1.9)was also significantly decreased compared to Lovo(49.9±5.4)and Lovo-NC cells(48.8±4.5)(P<0.05).ELISA assays showed significant reductions in Lovo-OPN-4 cells compared to Lovo and Lovo-NC cells with regard to the expression of VEGF(1687.85±167.84 ng/L vs 2348.54±143.80 ng/L and 2284.39±138.62 ng/L,respectively),MMP-2(2966.07±177.36μg/L vs 4084.74±349.54μg/L and 4011.41±424.48μg/L,respectively),MMP-9(3782.89±300.64μg/L vs5062.90±303.02μg/L and 4986.38±300.75μg/L,respectively)and uPA(1152.69±120.79μg/L vs1380.90±147.25μg/L and 1449.80±189.92μg/L,respectively)(all P<0.05).CONCLUSION:Knockdown of OPN gene expression suppresses colon cancer cell growth,adherence,invasion,and expression of angiogenic factors. | Xin-Lin Wu Kai-Jin Lin Ai-Ping Bai Wan-Xiang Wang Xing-Kai Meng Xiu-Lan Su Ming-Xing Hou Pei-De Dong Jun-Jing Zhang Zhao-Yang Wang Lin Shi | 2014 | World Journal of Gastroenterology2014,20,30: | 12 |
| 12 | An improved empirical wavelet transform method for rolling bearing fault diagnosis显示文摘Empirical wavelet transform(EWT)based on the scale space method has been widely used in rolling bearing fault diagnosis.However,using the scale space method to divide the frequency band,the redundant components can easily be separated,causing the band to rupture and making it difficult to extract rolling bearing fault characteristic frequency effectively.This paper develops a method for optimizing the frequency band region based on the frequency domain feature parameter set.The frequency domain feature parameter set includes two characteristic parameters:mean and variance.After adaptively dividing the frequency band by the scale space method,the mean and variance of each band are calculated.Sub-bands with mean and variance less than the main frequency band are combined with surrounding bands for subsequent analysis.An adaptive empirical wavelet filter on each frequency band is established to obtain the corresponding empirical mode.The margin factor sensitive to the shock pulse signal is introduced into the screening of empirical modes.The empirical mode with the largest margin factor is selected to envelope spectrum analysis.Simulation and experiment data show this method avoids over-segmentation and redundancy and can extract the fault characteristic frequency easier compared with only scale space methods. | HUANG HaiRun LI Ke SU WenSheng BAI JianYi XUE ZhiGang ZHOU Lang SU Lei PECHT Michael | 2020 | Science China(Technological Sciences)2020,63,11: | 10 |

| 14 | Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype. | Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu | 2021 | Cell Research2021,31,3: | 9 |
| 15 | Low-dose real-time X-ray imaging with nontoxic double perovskite scintillators显示文摘X-rays are widely used in probing inside information nondestructively,enabling broad applications in the medical radiography and electronic industries.X-ray imaging based on emerging lead halide perovskite scintillators has received extensive attention recently.However,the strong self-absorption,relatively low light yield and lead toxicity of these perovskites restrict their practical applications.Here,we report a series of nontoxic double-perovskite scintillators of Cs_(2)Ag_(0.6)Na_(0.4)In_(1-y)Bi_(y)Cl_(6).By controlling the content of the heavy atom Bi^(3+),the X-ray absorption coefficient,radiative emission efficiency,light yield and light decay were manipulated to maximise the scintillator performance.A light yield of up to 39,000±7000 photons/MeV for Cs_(2)Ag_(0.6)Na_(0.4)In_(0.85)Bi_(0.15)Cl_(6) was obtained,which is much higher than that for the previously reported lead halide perovskite colloidal CsPbBr_(3)(21,000 photons/MeV).The large Stokes shift between the radioluminescence(RL)and absorption spectra benefiting from self-trapped excitons(STEs)led to a negligible selfabsorption effect.Given the high light output and fast light decay of this scintillator,static X-ray imaging was attained under an extremely low dose of ∼1μGy_(air),and dynamic X-ray imaging of finger bending without a ghosting effect was demonstrated under a low-dose rate of 47.2μGy_(air) s^(−1).After thermal treatment at 85℃ for 50 h followed by X-ray irradiation for 50 h in ambient air,the scintillator performance in terms of the RL intensity and X-ray image quality remained almost unchanged.Our results shed light on exploring highly competitive scintillators beyond the scope of lead halide perovskites,not only for avoiding toxicity but also for better performance. | Wenjuan Zhu Wenbo Ma Yirong Su Zeng Chen Xinya Chen Yaoguang Ma Lizhong Bai Wenge Xiao Tianyu Liu Haiming Zhu Xiaofeng Liu Huafeng Liu Xu Liu Yang(Michael)Yang | 2020 | Light(Science & Applications)2020,9,1: | 9 |

| 18 | Reducing oxidative stress and hepatoprotective effect of water extracts from Pu-erh tea on rats with high-fat diet显示文摘Reducing oxidative stress and hepatoprotective effect of Pu-erh tea water extracts on rats fed with high-fat diet were researched for explaining health care of Pu-erh tea.Fifty SD rats were divided into five groups.The body weight was measured once a day.The malondialdehyde(MDA)and glucose(Glu)levels and the activities of alanine aminotransferase(ALT),aspartate aminotransferase(AST),nitric oxide synthase(NOS),and pyruvate kinase(PK)in serum were determined.Furthermore,the hepatic glycogen level(HGL)and the activities of hepatic total superoxide dismutase(T-SOD),catalase(CAT),and glutathione peroxidase(GSH-Px)were also measured after continuous administration for 12 weeks.The result demonstrated that Pu-erh extract caused the decreases in body weight,fat index,MDA and NOS levels,and the increases in hepatic T-SOD,CAT and GSH-Px activities,indicating that the extract may be due to inhibiting the increases of body weight and fat index,reducing oxidant stress state and inhibiting lipid peroxidation,thus decreasing the activities of ALT and AST,and protecting the liver in rat.Meanwhile,the extracts could increase the production of hepatic glycogen and the activity of PK,and reduce glucose level,protecting the liver from the diseases associated with type II diabetes. | Jingjing Su Xueqing Wang Wenjun Song Xiaoli Bai Changwen Li | 2016 | Food Science and Human Wellness2016,5,4: | 9 |
