| 1 | Clinical characteristics of fatal and recovered cases of coronavirus disease 2019 in Wuhan,China:a retrospective study显示文摘Background:The 2019 novel coronavirus has caused the outbreak of the acute respiratory disease in Wuhan,Hubei Province of China since December 2019.This study was performed to analyze the clinical characteristics of patients who succumbed to and who recovered from 2019 novel coronavirus disease(COVID-19).Methods:Clinical data were collected from two tertiary hospitals in Wuhan.A retrospective investigation was conducted to analyze the clinical characteristics of fatal cases of COVID-19(death group)and we compare them with recovered patients(recovered group).Continuous variables were analyzed using the Mann-WhitneyU test.Categorical variables were analyzed byχ2 test or Fisher exact test as appropriate.Results:Our study enrolled 109 COVID-19 patients who died during hospitalization and 116 recovered patients.The median age of the death group was older than the recovered group(69[62,74]vs.40[33,57]years,Z=9.738,P<0.001).More patients in the death group had underlying diseases(72.5%vs.41.4%,χ2=22.105,P<0.001).Patients in the death group had a significantly longer time of illness onset to hospitalization(10.0[6.5,12.0]vs.7.0[5.0,10.0]days,Z=3.216,P=0.001).On admission,the proportions of patients with symptoms of dyspnea(70.6%vs.19.0%,χ2=60.905,P<0.001)and expectoration(32.1%vs.12.1%,χ2=13.250,P<0.001)were significantly higher in the death group.The blood oxygen saturation was significantly lower in the death group(85[77,91]%vs.97[95,98]%,Z=10.625,P<0.001).The white blood cell(WBC)in death group was significantly higher on admission(7.23[4.87,11.17]vs.4.52[3.62,5.88]×109/L,Z=7.618,P<0.001).Patients in the death group exhibited significantly lower lymphocyte count(0.63[0.40,0.79]vs.1.00[0.72,1.27]×109/L,Z=8.037,P<0.001)and lymphocyte percentage(7.10[4.45,12.73]%vs.23.50[15.27,31.25]%,Z=10.315,P<0.001)on admission,and the lymphocyte percentage continued to decrease during hospitalization(7.10[4.45,12.73]%vs.2.91[1.79,6.13]%,Z=5.242,P<0.001).Alanine transaminase(22.00[15.00,34.00]vs.18.70[13.00,30.38]U/L,Z=2.592,P=0.010),aspartate transaminase(34.00[27.00,47.00]vs.22.00[17.65,31.75]U/L,Z=7.308,P<0.001),and creatinine levels(89.00[72.00,133.50]vs.65.00[54.60,78.75]μmol/L,Z=6.478,P<0.001)were significantly higher in the death group than those in the recovered group.C-reactive protein(CRP)levels were also significantly higher in the death group on admission(109.25[35.00,170.28]vs.3.22[1.04,21.80]mg/L,Z=10.206,P<0.001)and showed no significant improvement after treatment(109.25[35.00,170.28]vs.81.60[27.23,179.08]mg/L,Z=1.219,P=0.233).The patients in the death group had more complications such as acute respiratory distress syndrome(ARDS)(89.9%vs.8.6%,χ2=148.105,P<0.001),acute cardiac injury(59.6%vs.0.9%,χ2=93.222,P<0.001),acute kidney injury(18.3%vs.0%,χ2=23.257,P<0.001),shock(11.9%vs.0%,χ2=14.618,P<0.001),and disseminated intravascular coagulation(DIC)(6.4%vs.0%,χ2=7.655,P=0.006).Conclusions:Compared to the recovered group,more patients in the death group exhibited characteristics of advanced age,pre-existing comorbidities,dyspnea,oxygen saturation decrease,increased WBC count,decreased lymphocytes,and elevated CRP levels.More patients in the death group had complications such as ARDS,acute cardiac injury,acute kidney injury,shock,and DIC. | Yan Deng Wei Liu Kui Liu Yuan-Yuan Fang Jin Shang Ling Zhou Ke Wang Fan Leng Shuang Wei Lei Chen Hui-Guo Liu | 2020 | Chinese Medical Journal2020,,11: | 29 |
| 2 | Total glucosides of paeony attenuates animal psoriasis induced inflammatory response through inhibiting STAT1 and STAT3 phosphorylation显示文摘OBJECTIVE Psoriasis is an immune system meditated disease,especially T cells.It disturbed many people around the world and hard to therapy.Paeonia lactiflora Pall has been used as a medicine in china for thousands of years.Recent studies has found that the main component of Paeonia lactiflora Pall can alleviates the immune response in many diseases.In this study,we researched the effects and possible mechanisms of total glucosides of paeony(TGP)on animal psoriasis in order to study the therapeutic effects and mechanisms of TGP in 5%propranolol creaminduced psoriasis in guinea pigs and Imiquimod(IMQ)cream-induced psoriasis in mice.METHODS The effect of TGP was evaluated using a psoriasis-like model of guinea pigs and mice.Ear thickness was accessed,and pathology injury was observed by HE staining.The levels of serum IL-1β,IL-6,IL-12,IL-17,IL-23,TNF-α,and IFN-γ,skin IL-17A,IL-22 and orphan nuclear receptor(RORγt)mRNA expression,proliferating cell nuclear antigen(PCNA),total or phosphorylated signal transducers and activators of transcription(STAT1 and STAT3)were determined by ELISA,real time PCR,immu⁃nohistochemical staining,and Western blotting,respectively.RESULTS Compared with model group,TGP treatment decreased the ear thickness,improved pathology of psoriasis,alleviated IMQ-induced keratinocyte proliferation,reduced the inflammatory cytokine,and downregulated IL-17A,IL-22,and RORγt mRNA in mice.Further study indicated that TGP inhibited STAT1 and STAT3 phosphorylation in lesion skins of psoriasis-like mice.CONCLUSION TGP alleviates the symptoms of psoriasis-like guinea pigs and mice,and the possible mechanism may relate to inhibit T helper 17(TH17)cell differentiation and keratinocytes proliferation by inhibiting STAT1 and STAT3 phosphorylation. | LI Bin-bin HE Shu-cheng LIU Rui HUANG Liang-liang LIU Ge WANG Rui-xuan YANG Zhuo-yue LIU Xin-yi LENG Ye LIU Dan YE Cheng-yu LI Yun-man CHEN Yong-jian IN Hong FANG Wei-rong | 2019 | 中国药理学与毒理学杂志2019,33,9: | 21 |
| 3 | Facilitating effects of berberine on rat pancreatic islets through modulating hepatic nuclear factor 4 alpha expression and glucokinase activity显示文摘AIM: To observe the effect of berberine on insulin secretion in rat pancreatic islets and to explore its possible molecular mechanism. METHODS: Primary rat islets were isolated from male Sprague-Dawley rats by collagenase digestion and treated with different concentrations (1,3,10 and 30 μmol/L) of berberine or 1 μmol/L Glibenclamide (GB) for 24 h. Glucose-stimulated insulin secretion (GSIS) assay was conducted and insulin was determined by radioimmunoassay. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed to evaluate cytotoxicity. The mRNA level of hepatic nuclear factor 4 alpha (HNF4α) was determined by reverse transcription polymerase chain reaction (RT-PCR). Indirect immunofluorescence staining and Western blot analysis were employed to detect protein expression of HNF4α in the islets. Glucokinase (GK) activity was measured by spectrophotometric method. RESULTS: Berberine enhanced GSIS rather than basal insulin secretion dose-dependently in rat islets and showed no significant cytotoxicity on islet cells at the concentration of 10 μmol/L. Both mRNA and protein expressions of HNF4α were up-regulated by berberine in a dose-dependent manner,and GK activity was also increased accordingly. However,GB demonstrated no regulatory effects on HNF4α expression or GK activity. CONCLUSION: Berberine can enhance GSIS in rat islets,and probably exerts the insulinotropic effect via a pathway involving HNF4α and GK,which is distinct from sulphonylureas (SUs). | Zhi-Quan Wang Fu-Er Lu San-Hua Leng Xin-Sheng Fang Guang Chen Zeng-Si Wang Li-Ping Dong Zhong-Qing Yan | 2008 | World Journal of Gastroenterology2008,14,39: | 18 |
| 4 | Characterization and fine mapping of an early senescence mutant (es-t) in Oryza sativa L.显示文摘An es-t (early senescence-temporary) mutant, produced by ethylene methylsulfonate treatment of strain Nipponbare, was identified in rice. The leaves of es-t appeared yellow at the seedling stage, and had decreased chlorophyll content. Rust spots were found during growth in es-t, especially at the leaf margin and tip. The plants showed a typical early-senescence phenotype at the milky stage. The leaf surface of es-t appeared smoother than wild-type leaves under a scanning electron microscope, because the leaves lack siliceous protuberances around the stoma. Chloroplasts grow abnormally and are filled with many starch grains in es-t. Paraffin section analysis showed that the development of the sclerenchyma cells and vascular bundles were also abnormal in es-t. Genetic analysis indicated that es-t was controlled by a recessive gene, which was finely mapped to a 42-kb interval on chromosome 5. These results will facilitate the positional cloning and functional studies of the gene. | YANG YaoLong RAO YuChun LIU HuiJuan FANG YunXia DONG GuoJun HUANG LiChao LENG YuJia GUO LonBiao ZHANG GuangHeng HU Jiang GAO ZhenYu QIAN Qian ZENG DaLi | 2011 | Chinese Science Bulletin2011,56,23: | 8 |
| 5 | The complete reference genome for grapevine (Vitis vinifera L.) genetics and breeding显示文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs. | Xiaoya Shi Shuo Cao Xu Wang Siyang Huang Yue Wang Zhongjie Liu Wenwen Liu Xiangpeng Leng Yanling Peng Nan Wang Yiwen Wang Zhiyao Ma Xiaodong Xu Fan Zhang Hui Xue Haixia Zhong Yi Wang Kekun Zhang Amandine Velt Komlan Avia Daniela Holtgräwe Jérôme Grimplet JoséTomás Matus Doreen Ware Xinyu Wu Haibo Wang Chonghuai Liu Yuling Fang Camille Rustenholz Zongming Cheng Hua Xiao Yongfeng Zhou | 2023 | Horticulture Research2023,10,5: | 3 |
| 6 | Oral microbiota in the oral-genitourinary axis:identifying periodontitis as a potential risk of genitourinary cancers显示文摘Periodontitis has been proposed as a novel risk factor of genitourinary cancers:although periodontitis and genitourinary cancers are two totally distinct types of disorders,epidemiological and clinical studies,have established associations between them.Dysbiosis of oral microbiota has already been established as a major factor contributing to periodontitis.Recent emerging epidemiological evidence and the detection of oral microbiota in genitourinary organs indicate the presence of an oral-genitourinary axis and oral microbiota may be involved in the pathogenesis of genitourinary cancers.Therefore,oral microbiota provides the bridge between periodontitis and genitourinary cancers.We have carried out this narrative review which summarizes epidemiological studies exploring the association between periodontitis and genitourinary cancers.We have also highlighted the current evidence demonstrating the capacity of oral microbiota to regulate almost all hallmarks of cancer,and proposed the potential mechanisms of oral microbiota in the development of genitourinary cancers. | Shuai Yuan Cheng Fang Wei-Dong Leng Lan Wu Bing-Hui Li Xing-Huan Wang Hailiang Hu Xian-Tao Zeng | 2021 | Military Medical Research2021,8,4: | 3 |
| 7 | The genome of the recretohalophyte Limonium bicolor provides insights into salt gland development and salinity adaptation during terrestrial evolution显示文摘Halophytes have evolved specialized strategies to cope with high salinity.The extreme halophyte sea lavender(Limonium bicolor)lacks trichomes but possesses salt glands on its epidermis that can excrete harmful ions,such as sodium,to avoid salt damage.Here,we report a high-quality,2.92-Gb,chromosome-scale L.bicolor genome assembly based on a combination of Illumina short reads,single-molecule,real-time long reads,chromosome conformation capture(Hi-C)data,and Bionano genome maps,greatly enriching the genomic information on recretohalophytes with multicellular salt glands.Although the L.bicolor genome contains genes that show similarity to trichome fate genes from Arabidopsis thaliana,it lacks homologs of the decision fate genes GLABRA3,ENHANCER OF GLABRA3,GLABRA2,TRANSPARENT TESTA GLABRA2,and SIAMESE,providing a molecular explanation for the absence of trichomes in this species.We identified key genes(LbHLH and LbTTG1)controlling salt gland development among classical trichome homologous genes and confirmed their roles by showing that their mutations markedly disrupted salt gland initiation,salt secretion,and salt tolerance,thus offering genetic support for the long-standing hypothesis that salt glands and trichomes may share a common origin.In addition,a whole-genome duplication event occurred in the L.bicolor genome after its divergence from Tartary buckwheat and may have contributed to its adaptation to high salinity.The L.bicolor genome resource and genetic evidence reported in this study provide profound insights into plant salt tolerance mechanisms that may facilitate the engineering of salt-tolerant crops. | Fang Yuan Xi Wang Boqing Zhao Xiaojing Xu Miao Shi Bingying Leng Xinxiu Dong Chaoxia Lu Zhongtao Feng Jianrong Guo Guoliang Han Haikuan Zhang Jianwei Huang Min Chen Bao-Shan Wang | 2022 | Molecular Plant2022,15,6: | 3 |

| 9 | The Correlation Between Decreased Ornithine Level and Alleviation of Rheumatoid Arthritis Patients Assessed by a Randomized,Placebo-Controlled,Double-Blind Clinical Trial of Sinomenine显示文摘Sinomenine(SIN)is commonly used as part of rheumatoid arthritis(RA)therapy in China,but there is still no published evidence of the efficacy of SIN monotherapy.This work investigates the efficacy and safety of SIN in treating RA patients and analyzes the correlation between ornithine level and the alleviation of disease activity in RA patients.In this 24 week,randomized,placebo-controlled,double-blind clinical trial,people with mild to moderate RA were randomly assigned(1:1:1,stratified by hospital)to receive SIN(120 mg,twice daily),methotrexate(MTX)(10 mg per week),or SIN+MTX therapy.The primary outcome was the proportion of patients who achieved a 50%improvement in the American College of Rheumatology(ACR50)criteria at week 24 and who showed improvement according to the clinical disease activity index(CDAI).In this prospective subgroup analysis,we also assessed whether the 24-week alterations of disease activity in the treatment group were significantly correlated to the levels of blood ornithine.Of the 135 enrolled participants,38,39,and 36 patients were treated with SIN,MTX,and SIN+MTX,respectively.In the SIN-treated group,52.63%of patients achieved ACR50 after 24-weeks of treatment,which was comparable to the results in the MTX-treated and SIN+MTX-treated groups.Hepatic and gastrointestinal disorders were the main adverse events;however,the ratio of patients suffering from hepatic disorder in the SIN group(1/38)was much lower than that in the MTX(10/39)and SIN+MTX(8/36)groups.A total of 221 serum samples were collected at the four follow-up time points in the three treatments,and the levels of ornithine,citrulline,and arginine were obtained through ultrahigh performance liquid chromatography-quadrupole time-of-flight mass spectrometry(UHPLC-Q-TOF/MS).The serum ornithine level decreased after the 24-week treatment along with a decrease in disease activity,and may reflect therapeutic responses with a sensitivity value of 80%.In conclusion,SIN revealed a comparable efficacy to MTX for treating RA patients,but with fewer side effects.In addition,the serum ornithine level was found for the first time to have a close correlation with the alleviation of RA,which shows the value of this measure as an assessment indicator of drugs in treating RA. | Ying Shi Hu-Dan Pan Jian-Lin Wu Qing-Hua Zou Xin-Yi Xie Hong-Gang Li Hua Zhou Xi-Qing Bian Wen-Fei Leng Can-Jian Wang Ya-Feng Wang Yong-Fei Fang Liang Liu | 2022 | Engineering2022,,9: | 2 |

| 11 | Micro and nanolattice fabrication using projection micro litho stereo exposure additive manufacturing techniques and synchrotron X-ray 3D imaging-based defect characterization显示文摘Synchrotron radiation X-ray micro-computed tomography(SR-μCT)is a 3D imaging technique that is widely employed for the characterization of defects in advanced materials and structures.In this study,we characterize several typical defects in octettruss and re-entrant 3D lattice structures by using SR-μCT.The 3D micro-lattice structures are manufactured using projection micro litho stereo exposure(PμLSE)additive manufacturing technology.The as-fabricated 3D lattice samples are characterized using optical microscopy,and subsequently,by SR-μCT.Further more,a statistical analysis is performed to characterize the surface roughness and internal defects qualitatively,whereby the statistical geometrical parameters of struts along different directions and strut joints are analyzed and classified.Consequently,several typical defects are identified:(1)holes at the joints of the strut and irregular diameter deviations of the strut in the octet-truss lattice structure;(2)irregular diameter variations,bulges,dislocations,grooves,accumulations,and torsion in the re-entrant lattice structure.All of these defects are related to the building direction,the weight of the structure,bubbles,dust,and impurities during the PμLSE additive manufacturing process. | HU WenXia LIU LiWu WU WenWang XI Li LENG JinSong FANG DaiNing | 2020 | Science China(Technological Sciences)2020,63,4: | 2 |
| 12 | Risk stratification in symptomatic intracranial atherosclerotic disease with conventional vascular risk factors and cerebral haemodynamics显示文摘Background and purpose Symptomatic intracranial atherosclerotic stenosis(sICAS)is associated with a considerable risk of recurrent stroke despite contemporarily optimal medical treatment.Severity of luminal stenosis in sICAS and its haemodynamic significance quantified with computational fluid dynamics(CFD)models were associated with the risk of stroke recurrence.We aimed to develop and compare stroke risk prediction nomograms in sICAS,based on vascular risk factors and these metrics.Methods Patients with 50%-99%sICAS confirmed in CT angiography(CTA)were enrolled.Conventional vascular risk factors were collected.Severity of luminal stenosis in sICAS was dichotomised as moderate(50%-69%)and severe(70%-99%).Translesional pressure ratio(PR)and wall shear stress ratio(WSSR)were quantified via CTA-based CFD modelling;the haemodynamic status of sICAS was classified as normal(normal PR&WSSR),intermediate(otherwise)and abnormal(abnormal PR&WSSR).All patients received guideline-recommended medical treatment.We developed and compared performance of nomograms composed of these variables and independent predictors identified in multivariate logistic regression,in predicting the primary outcome,recurrent ischaemic stroke in the same territory(SIT)within 1 year.Results Among 245 sICAS patients,20(8.2%)had SIT.The D2H2A nomogram,incorporating diabetes,dyslipidaemia,haemodynamic status of sICAS,hypertension and age≥50 years,showed good calibration(P for Hosmer-Lemeshow test=0.560)and discrimination(C-statistic 0.73,95%CI 0.60 to 0.85).It also had better performance in risk reclassification and provided larger net benefits in decision curve analysis,compared with nomograms composed of conventional vascular risk factors only,and plus the severity of luminal stenosis in sICAS.Sensitivity analysis in patients with anterior-circulation sICAS showed similar results.Conclusions The D2H2A nomogram,incorporating conventional vascular risk factors and the haemodynamic significance of sICAS as assessed in CFD models,could be a useful tool to stratify sICAS patients for the risk of recurrent stroke under contemporarily optimal medical treatment. | Xuan Tian Hui Fang Linfang Lan Hing Lung Ip Jill Abrigo Haipeng Liu Lina Zheng Florence S Y Fan Sze Ho Ma Bonaventure Ip Bo Song Yuming Xu Jingwei Li Bing Zhang Yun Xu Yannie O Y Soo Vincent Mok Ka Sing Wong Thomas W Leung Xinyi Leng | 2023 | Stroke & Vascular Neurology2023,8,1: | 2 |
