2A seven-gene-deleted African swine fever virus is safe and effective as a live attenuated vaccine in pigs显示文摘African swine fever(ASF)is a devastating infectious disease in swine that is severely threatening the global pig industry.An efficacious vaccine is urgently required.Here,we used the Chinese ASFV HLJ/18 as a backbone and generated a series of genedeleted viruses.The virulence,immunogenicity,safety,and protective efficacy evaluation in specific-pathogen-free pigs,commercial pigs,and pregnant sows indicated that one virus,namely HLJ/18-7GD,which has seven genes deleted,is fully attenuated in pigs,cannot convert to the virulent strain,and provides complete protection of pigs against lethal ASFV challenge.Our study shows that HLJ/-18-7GD is a safe and effective vaccine against ASFV,and as such is expected to play an important role in controlling the spread of ASFV.Weiye Chen Dongming Zhao Xijun He Renqiang Liu Zilong Wang Xianfeng Zhang Fang Li Dan Shan Hefeng Chen Jiwen Zhang Lulu Wang Zhiyuan Wen Xijun Wang Yuntao Guan Jinxiong Liu Zhigao Bu 2020Science China(Life Sciences)2020,63,5:72

5Emergence and prevalence of naturally occurring lower virulent African swine fever viruses in domestic pigs in China in 2020显示文摘African swine fever virus(ASFV)has been circulating in China for more than two years,and it is not clear whether the biological properties of the virus have changed.Here,we report on our surveillance of ASFVs in seven provinces of China,from June to December,2020.A total of 22 viruses were isolated and characterized as genotype II ASFVs,with mutations,deletions,insertions,or short-fragment replacement occurring in all isolates compared with Pig/HLJ/2018(HLJ/18),the earliest isolate in China.Eleven isolates had four different types of natural mutations or deletion in the EP402R gene and displayed a nonhemadsorbing(non-HAD)phenotype.Four isolates were tested for virulence in pigs;two were found to be as highly lethal as HLJ/18.However,two non-HAD isolates showed lower virulence but were highly transmissible;infection with 106 TCID50 dose was partially lethal and caused acute or sub-acute disease,whereas 103 TCID50 dose caused non-lethal,sub-acute or chronic disease,and persistent infection.The emergence of lower virulent natural mutants brings greater difficulty to the early diagnosis of ASF and creates new challenges for ASFV control.Encheng Sun Zhenjiang Zhang Zilong Wang Xijun He Xianfeng Zhang Lulu Wang Wenqing Wang Lianyu Huang Fei Xi Haoyue Huangfu Ghebremedhin Tsegay Hong Huo Jianhong Sun Zhijun Tian Wei Xia Xuewu Yu Fang Li Renqiang Liu Yuntao Guan Dongming Zhao Zhigao Bu 2021Science China(Life Sciences)2021,64,5:46

7Level of circulating PD-L1 expression in patients with advanced gastric cancer and its clinical implications显示文摘Objective:The programmed cell death-1 receptor/programmed cell death-1 ligand(PD-1/PD-L1) pathway plays a crucial role in tumor evasion from host immunity.This study was designed to evaluate the association between circulating PD-L1 expression and prognosis in patients with advanced gastric cancer.Methods:Totally 80 advanced gastric cancer patients and 40 health controls from Beijing Cancer Hospital were enrolled in the present study.Circulating PD-L1 expression was tested by enzymelinked immunosorbent assay(ELISA).The associations between the expression level of PD-L1 and clinicopathological features and prognosis were analyzed statistically.Results:Expression of PD-L1 in advanced gastric cancer patients was significantly up-regulated compared with health people(P=0.006).The expression of PD-L1 was significantly correlated with differentiation and lymph node metastasis(P=0.026 and P=0.041,respectively).Although we didn't find significant difference in all advanced gastric cancer patients with different PD-L1 expression,the adenocarcinoma patients with higher up-regulated PD-L1 expression had much better prognosis than low expression patients(65.6% vs.44.7%,P=0.028).Conclusions:PD-L1 was elevated in advance gastric cancer patients and may play an important role in tumor immune evasion and patients prognosis.Zhixue Zheng Zhaode Bu Xijuan Liu Lianhai Zhang Ziyu Li Aiwen Wu Xiaojiang Wu Xiaojing Cheng Xiaofang Xing Hong Du Xiaohong Wang Ying Hu Jiafu Ji 2014Chinese Journal of Cancer Research2014,26,1:37
8Clinical Research on Alzheimer's Disease: Progress and Perspectives显示文摘Alzheimer's disease(AD), the most common type of dementia, is becoming a major challenge for global health and social care. However, the current understanding of AD pathogenesis is limited, and no early diagnosis and disease-modifying therapy are currently available. During the past year, significant progress has been made in clinical research on the diagnosis, prevention, and treatment of AD.In this review, we summarize the latest achievements,including diagnostic biomarkers, polygenic hazard score,amyloid and tau PET imaging, clinical trials targeting amyloid-beta(Ab), tau, and neurotransmitters, early intervention, and primary prevention and systemic intervention approaches, and provide novel perspectives for further efforts to understand and cure the disease.Bin-Lu Sun Wei-Wei Li Chi Zhu Wang-Sheng Jin Fan Zeng Yu-Hui Liu Xian-Le Bu Jie Zhu Xiu-Qing Yao Yan-Jiang Wang 2018Neuroscience Bulletin2018,34,6:29

12Biodegradable chitosan scaffolds containing microspheres as carriers for controlled transforming growth factor-β_1 delivery for cartilage tissue engineering显示文摘Background Natural articular cartilage has a limited capacity for spontaneous regeneration.Controlled release oftransforming growth factor-β_1(TGF-β_1)to cartilage defects can enhance chondrogenesis.In this study,we assessed thefeasibility of using biodegradable chitosan microspheres as carriers for controlled TGF-β_1 delivery and the effect ofreleased TGF-β_1 on the chondrogenic potential of chondrocytes.Methods Chitosan scaffolds and chitosan microspheres loaded with TGF-β_1 were prepared by the freeze-drying andthe emulsion-crosslinking method respectively.In vitro drug release kinetics,as measured by enzyme-linkedimmunosorbent assay,was monitored for 7 days.Lysozyme degradation was performed for 4 weeks to detect in vitrodegradability of the scaffolds and the microspheres.Rabbit chondrocytes were seeded on the scaffolds containingTGF-β_1 microspheres and incubated in vitro for 3 weeks.Histological examination and type Ⅱcollagenimmunohistochemical staining was performed to evaluate the effects of released TGF-β_1 on cell adhesivity,proliferationand synthesis of the extracellular matrix.Results TGF-β_1 was encapsulated into chitosan microspheres and the encapsulation efficiency of TGF-β_1 was high(90.1%).During 4 weeks of incubation in lysozyme solution for in vitro degradation,the mass of both the scaffolds andthe microspheres decreased continuously and significant morphological changes was noticed.From the releaseexperiments,it was found that TGF-β_1 could be released from the microspheres in a multiphasic fashion including aninitial burst phase,a slow linear release phase and a plateau phase.The release amount of TGF-β_1 was 37.4%,50.7%,61.3%,and 63.5% for 1,3,5,and 7 days respectively.At 21 days after cultivation,type Ⅱ collagen immunohistochemicalstaining was performed.The mean percentage of positive cells for collagen type II in control group(32.7%±10.4%)wassignificantly lower than that in the controlled TGF-β_1 release group(92.4%±4.8%,P<0.05).Both the proliferation rateand production of collagen type Ⅱ in the transforming growth factor-β_1 microsphere incorporated scaffolds weresignificantly higher than those in the scaffolds without microspheres,indicating that the activity of TGF-β_1 was retainedduring microsphere fabrication and after growth factor release.Conclusion Chitosan microspheres can serve as delivery vehicles for controlled release of TGF-β_1,and the releasedgrowth factor can augment chondrocytes proliferation and synthesis of extracellular matrix.Chitosan scaffoldsincorporated with chitosan microspheres loaded with TGF-β_1 possess a promising potential to be applied for controlledcytokine delivery and cartilage tissue engineering.CAI Dao-zhang ZENG Chun QUAN Da-ping BU Li-si WANG Kun LU Hua-ding LI Xiao-feng 2007Chinese Medical Journal2007,,3:20
13Interspecific and intraspecific variation in specific root length drives aboveground biodiversity effects in young experimental forest stands显示文摘Aims Although the net biodiversity effect(NE)can be statistically partitioned into complementarity and selection effects(CE and SE),there are different underlying mechanisms that can cause a certain partitioning.Our objective was to assess the role of resource partitioning and species interactions as two important mechanisms that can bring about CEs by interspecific and intraspecific trait variation.Methods We measured tree height of 2493 living individuals in 57 plots and specific root length(SRL)on first-order roots of 368 of these individuals across different species richness levels(1,2,4,8 species)in a large-scale forest biodiversity and ecosystem functioning experiment in subtropical China(BEF-China)established in 2009.We describe the effects of resource partitioning between species by a fixed component of interspecific functional diversity(RaoQ)and further effects of species interactions by variable components of interspecific and intraspecific functional diversity(community weighted trait similarity and trait dissimilarity,CWS and CWD).Finally,we examined the relationships between biodiversity effects on stand-level tree height and functional diversity(RaoQ,CWS and CWD)in SRL using linear regression and assessed the relative importance of these three components of functional diversity in explaining the diversity effects.Important Findings Our results show that species richness significantly affected SRL in five and tree height in ten out of 16 species.A positive NE was generally brought about by a positive CE on stand-level tree height and related to high values of RaoQ and CWS in SRL.A positive CE was related to high values of all three components of root functional diversity(RaoQ,CWS and CWD).Our study suggests that both resource partitioning and species interactions are the underlying mechanisms of biodiversity effects on stand-level tree growth in subtropical forest.Wensheng Bu Bernhard Schmid Xiaojuan Liu Ying Li Werner Härdtle Goddert von Oheimb Yu Liang Zhenkai Sun Yuanyuan Huang Helge Bruelheide Keping Ma 2017Journal of Plant Ecology2017,10,1:18

15LGR5 is a promising biomarker for patients with stage Ⅰ and Ⅱ gastric cancer显示文摘Objective: To investigate Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) expressions in gastric cancer and to evaluate its clinical significance. Methods: LGR5 expression was assessed by immunohistochemistry in 257 gastric cancer patients after surgery. The relationships between LGR5 expression and clinicopathological features and patients prognosis were statistically analyzed. Results: The expression of LGR5 was significantly higher in gastric cancers as a cancer stem cell marker than in adjacent normal tissues (P<0.001), and more frequently in patients with intestinal type, well-moderate differentiation and stage Ⅰ and Ⅱ (P<0.05). Although we found gastric cancer patients with LGR5 positive expression had a poorer prognosis, it didn't meet statistical significance (P>0.05). LGR5 negative expression was significantly related to the favorable overall survival in stage Ⅰ and Ⅱ gastric cancer patients (P<0.05). Furthermore, patients with high LGR5 expression tended to be more likely to get progression and have poorer progress-free survival (P<0.05). Multivariate Cox regression analysis revealed that LGR5 expression was an independent factor of overall survival for the patients with stage Ⅰ and Ⅱ gastric cancer (P<0.05). Conclusions: Our results show that LGR5 may play an important role in tumorigenesis and progression and would be a powerful marker to predict the prognosis of patients with stage Ⅰ and Ⅱ gastric cancer.Zhaode Bu Zhixue Zheng Lianhai Zhang Ziyu Li Yu Sun Bin Dong Aiwen Wu Xiaojiang Wu Xiaohong Wang Xiaojing Cheng Xiaofang Xing Yingai Li Hong Du Jiafu Ji 2013Chinese Journal of Cancer Research2013,25,1:17
16Dynamics of Saline-alkali Land and Its Ecological Regionalization in Western Songnen Plain, China显示文摘As the important reserve land resources for food production,saline-alkali land should play a significant role to ensure the national food security in the context of global food crisis. The western Songnen Plain is one of main distribution regions of saline-alkali land in China,with great potential in agricultural development. In this study,the extent,transformation,spatial distribution and temporal change of saline-alkali land in the western Songnen Plain during 1954–2005 were investigated by using remote sensing and GIS spatial analysis methods. Saline-alkali land change was detected from a temporal series of topographic maps in 1954,satellite images of Landsat MSS in 1976,Landsat TM/ETM in 1988,2000 and 2005 through artificial visual interpretation. The results indicated a significant expansion in saline-alkali land area and aggravation in salinization. The area of saline-alkali land had increased from 401.48×103 ha in 1954 to 1 097.45×103 ha in 2005. While the ratio of light,moderate and serious salinized land areas changed from 6.72︰2.92︰1.00 to 1.25︰1.06︰1.00 in the study period. Grassland,cropland,swampland and water body were the major land use and land cover types from which saline-alkali land transformed. And the secondary salinization occured mainly in Da′an City,Tongyu County,Changling County,Daqing City,Dorbod Mongolian Autonomous County and Zhaoyuan County. Finally,seven large ecoregions and 14 corresponding sub-ecoregions were delineated out based on spatio-temopral dynamic characteristics of saline-alkali land and geo-relational environmental attributes. According to the results,measures of amelioration and ways of development of saline-alkali land in the western Songnen Plain were put forward.YANG Jiuchun ZHANG Shuwen LI Ying BU Kun ZHANG Yubo CHANG Liping ZHANG Yangzhen 2010Chinese Geographical Science2010,20,2:17

18Experimental study of an aircraft fuel tank inerting system显示文摘In this work, a simulated aircraft fuel tank inerting system has been successfully established based on a model tank. Experiments were conducted to investigate the influences of different operating parameters on the inerting effectiveness of the system, including flow rate of the inert gas(nitrogen-enriched air), inert gas concentration, fuel load of the tank and different inerting approaches. The experimental results show that under the same operating conditions, the time span of a complete inerting process decreased as the flow rate of inert gas was increased; the time span using the inert gas with 5% oxygen concentration was much longer than that using pure nitrogen;when the fuel tank was inerted using the ullage washing approach, the time span increased as the fuel load was decreased; the ullage washing approach showed the best inerting performance when the time span of a complete inerting process was the evaluation criterion, but when the decrease of dissolved oxygen concentration in the fuel was also considered to characterize the inerting effectiveness, the approach of ullage washing and fuel scrubbing at the same time was the most effective.Cai Yan Bu Xueqin Lin Guiping Sun Bing Zeng Yu Li Zixuan 2015Chinese Journal of Aeronautics2015,28,2:15
19Serum cystatin C levels are negatively correlated with post-stroke cognitive dysfunction显示文摘Stroke is the leading cause of death and long-term disability worldwide,and cognitive impairment and dementia are major complications of ischemic stroke.Cystatin C (CysC) has been found to be a neuroprotective factor in animal studies.However,the relationship between CysC levels and cognitive dysfunction in previous studies has revealed different results.This prospective observational study investigated the correlation between serum CysC levels and post-stroke cognitive dysfunction at 3 months.Data from 638 patients were obtained from the China Antihypertensive Trial in Acute Ischemic Stroke (CATIS).Cognitive dysfunction was assessed using the Mini-Mental State Examination (MMSE) at 3 months after stroke.According to the MMSE score,308 patients (52.9%) had post-stroke cognitive dysfunction.After adjusting for potential confounding factors,the odds ratio (95% CI) of post-stroke cognitive dysfunction for the highest quartile of serum CysC levels was 0.54 (0.30–0.98),compared with the lowest quartile.The correlation between serum CysC and cognitive dysfunction was modified by renal function status.We observed a negative linear dose-response correlation between CysC and cognitive dysfunction in patients with normal renal function (Plinearity = 0.044),but not in those with abnormal renal function.Elevated serum CysC levels were correlated with a low risk of 3-month cognitive dysfunction in patients with acute ischemic stroke,especially in those with normal renal function.The current results suggest that CysC is a protective factor for post-stroke cognitive dysfunction,and could be used to treat post-stroke cognitive dysfunction.The CATIS study was approved by the Institutional Review Boards at Soochow University from China (approval No.2012-02) on December 30,2012,and was registered at ClinicalTrials.gov (identifier No.NCT01840072) on April 25,2013.Dao-Xia Guo Zheng-Bao Zhu Chong-Ke Zhong Xiao-Qing Bu Li-Hua Chen Tan Xu Li-Bing Guo Jin-Tao Zhang Dong Li Jian-Hui Zhang Zhong Ju Chung-Shiuan Chen Jing Chen Yong-Hong Zhang Jiang He 2020Neural Regeneration Research2020,15,5:14
20A novel CFTR mutation found in a Chinese patient with cystic fibrosis显示文摘Background Cystic fibrosis (CF) is rare in Chinese. We investigated the mutations in the gene of cystic fibrosis transmembrane conductance regulator (CFTR) in a Chinese CF patient and reviewed the clinical features, gene mutations in Chinese CF cases. Methods Blood samples were collected from a previously reported CF girl and her parents. The 24 coding exons of CFTR of the proband were amplified and sequenced. Results A Chinese girl of 16 years old was diagnosed as CF at the age of 14. She had recurrent productive cough with bronchiectasis in bilateral upper lobes, parasinusitis and otitis media, but without pancreatic involvement. Her sweat chloride was (108.9 ±3.3) mmol/L. A heterozygous novel missense mutation of 699 C→ A which results in the amino acid change of N189K was identified in exon 5. In addition, a heterozygous 3821-3823 delT mutation in exon 19 was found in CFTR. The mutation 699C→A was inherited from her father, and the 3821-3823delT mutation was from her mother. Twenty patients with CF in Chinese reported from 1974 to 2004 were also reviewed. DelF508 mutation was not found in the nine cases whose CFTR mutations were analyzed. Conclusions The CF proband carries two heterozygous mutations (699C→A and 3821-3823delT) in CFTR. 699C→A mutation is a novel mutation which is not reported previously. Review of reported Chinese cases suggests that the genotype of Chinese CF may be different from those of white cases. More studies are needed to understand the spectra of CFTR and clinical CF features in Chinese.LI Nan PEI Pei BU Ding-fang HE Bing WANG Guang-fa 2006Chinese Medical Journal2006,,2:14
