1A Review on Rill Erosion Process and Its Influencing Factors显示文摘Rills are frequently observed on slope farmlands and rill erosion significantly contributes to sediment yields. This paper focuses on reviewing the various factors affecting rill erosion processes and the threshold conditions of rill initiation. Six factors, including rainfall, runoff, soil, topography, vegetation and tillage system, are discussed. Rill initiation and network are explored. Runoff erosivity and soil erodibility are recognized as two direct factors affecting rill erosion and other types of factors may have indirect influences on rill erosion through increasing or decreasing the effects of the direct factors. Certain conditions are necessary for rill initiation and the critical conditions are different with different factors. Future studies should be focused on 1) the dynamic changes of rill networks; 2) the combined effect of multiple factors; and 3) the relationships of threshold values with other related factors.SUN Liying FANG Haiyan QI Deli LI Junlan CAI Qiangguo 2013Chinese Geographical Science2013,23,4:11
2Micro/nano-structured TiO2 surface with dual-functional antibacterial effects for biomedical applications显示文摘Implant-associated infections are generally difficult to cure owing to the bacterial antibiotic resistance which is attributed to the widespread usage of antibiotics.Given the global threat and increasing influence of antibiotic resistance,there is an urgent demand to explore novel antibacterial strategies other than using antibiotics.Recently,using a certain surface topography to provide a more persistent antibacterial solution attracts more and more attention.However,the clinical application of biomimetic nano-pillar array is not satisfactory,mainly because its antibacterial ability against Gram-positive strain is not good enough.Thus,the pillar array should be equipped with other antibacterial agents to fulfill the bacteriostatic and bactericidal requirements of clinical application.Here,we designed a novel model substrate which was a combination of periodic micro/nano-pillar array and TiO2 for basically understanding the topographical bacteriostatic effects of periodic micro/nano-pillar array and the photocatalytic bactericidal activity of TiO2.Such innovation may potentially exert the synergistic effects by integrating the persistent topographical antibacterial activity and the non-invasive X-ray induced photocatalytic antibacterial property of TiO2 to combat against antibiotic-resistant implant-associated infections.First,to separately verify the topographical antibacterial activity of TiO2 periodic micro/nano-pillar array,we systematically investigated its effects on bacterial adhesion,growth,proliferation,and viability in the dark without involving the photocatalysis of TiO2.The pillar array with sub-micron motif size can significantly inhibit the adhesion,growth,and proliferation of Staphylococcus aureus(S.aureus)and Escherichia coli(E.coli).Such antibacterial ability is mainly attributed to a spatial confinement size-effect and limited contact area availability generated by the special topography of pillar array.Moreover,the pillar array is not lethal to S.aureus and E.coli in 24 h.Then,the X-ray induced photocatalytic antibacterial property of TiO2 periodic micro/nano-pillar array in vitro and in vivo will be systematically studied in a future work.This study could shed light on the direction of surface topography design for future medical implants to combat against antibiotic-resistant implant-associated infections without using antibiotics.Xiang Ge Chengzu Ren Yonghui Ding Guang Chen Xiong Lu Kefeng Wang Fuzeng Ren Meng Yang Zhuochen Wang Junlan Li Xinxin An Bao Qian Yang Leng 2019Bioactive Materials2019,4,1:8
3Detection of serum IgM and IgG for COVID-19 diagnosis显示文摘Dear Editor,Infection with the novel coronavirus(SARS-CoV-2,which is the virus responsible for the coronavirus disease 2019(COVID-19))was first reported in Wuhan,China on December 31,2019.The outbreak of COVID-19 remains ongoing and was linked to more than 80,000 infected patients and more than 3,000 deaths in China as of March 7,2020(Holshue et al.,2020).Ling Zhong Junlan Chuan Bo Gong Ping Shuai Yu Zhou Yi Zhang Zhilin Jiang Dingding Zhang Xiaoqi Liu Shi Ma Yi Huang He Lin Qingwei Wang Lulin Huang Dan Jiang Fang Hao Juan Tang Chunqi Zheng Hua Yu Zhibin Wang Qi Jiang Tao Zeng Mei Luo Fanwei Zeng Fanxin Zeng Jianghai Liu Junxi Tian Yu Xu Tengxiang Long Kaiju Xu Xingxiang Yang Yuping Liu Yi Shi Li Jiang Zhenglin Yang 2020Science China(Life Sciences)2020,63,5:8
4Mesozoic lithofacies palaeogeography and petroleum prospectivity in North Carnarvon Basin,Australia显示文摘The North Carnarvon Basin, which lies in the North West Shelf of Australia, is highly rich in gas resources. As a typical passive marginal basin, it experienced the pre-rifting, early rifting, main rifting, late rifting, post-rifting sagging and passive margin stages. The basin was mainly filled with thick Mesozoic-Cenozoic sediments, of which the Mesozoic hosts the principal source, reservoir and seal intervals. Mesozoic palaeogeography has an important control on the oil and gas distribution. Triassic gas-prone source rocks of deltaic origin deter-mine the high endowment of natural gases in the North Carnarvon Basin. The more restricted distribution of oil accumulations is controlled by oil source rocks in the Upper Jurassic Dingo Claystone. The Muderong Shale deposited in the Early Cretaceous marine transgression provides the effective regional seal for the underlying oil and gas reservoirs.Tao Chongzhi Bai Guoping Liu Junlan Deng Chao Lu Xiaoxin Liu Houwu Wang Dapeng 2013Journal of Palaeogeography2013,2,1:7
5Ultrasonographic evaluation of enthesitis in patients with ankylosing spondylitis显示文摘The aim of this study was to assess sensitivity and responsiveness of power Doppler ultrasound(PDUS) in detecting enthesitis for ankylosing spondylitis(AS) patients compared to clinical examinations.Twenty AS patients initiating etanerceptunderwent clinical and PDUS examinations of six bilateral entheseal sites at baseline and after 1,2 and 3 months of treatment.Clinical and PDUS examinations identified at least one entheseal lesion in nine(45%)and 19(95%) patients,respectively.Furthermore,of 240 entheseal sites examined in these 20 patients,PDUS detected 123 entheseal lesions(51.3%of sites),compared with only 47 entheseal lesions(19.6%) detected by clinical examination(P<0.05).The entheseal lesions found on PDUS were most commonly identified by calcification(33.3%),tendon edema(29.2%),abnormal blood flow(25.8%),a thickened tendon(22.1%),cortical irregularity(12.9%),bony erosions(9.6%) and bursitis at the tendon insertion to the bone cortex(7.1%).Improvements in clinical symptoms and laboratory parameters,and significant decreases in PDUS scores were observed following treatment with etanercept.Improvements in PDUS scores continued during follow-up in patients who entered remission following treatment.In conclusion,PDUS improves detection of structural and inflammatory abnormalities of the enthesis in AS compared to physical examination.In addition,PDUS may be useful inascertaining medications.Huayong Zhang Jun Liang Junlan Qiu Fan Wang Lingyun Sun 2017The Journal of Biomedical Research2017,31,2:6
6Multicenter phaseⅡstudy of apatinib single or combination therapy in HER2-negative breast cancer involving chest wall metastasis显示文摘Objective:Breast cancer(BC)with chest wall metastasis(CWM)usually shows rich neovascularization.This trial explored the clinical effect of apatinib on human epidermal growth factor receptor 2(HER2)-negative advanced BC involving CWM.Methods:This trial involved four centers in China and was conducted from September 2016 to March 2020.Patients received apatinib 500 mg/d[either alone or with endocrine therapy if hormone receptor-positive(HR+)]until disease progression or unacceptable toxicity.Progression-free survival(PFS)was the primary endpoint.Results:We evaluated 26 patients for efficacy.The median PFS(mPFS)and median overall survival(mOS)were4.9[range:2.0-28.5;95%confidence interval(95%CI):2.1-8.3]months and 18(range:3-55;95%CI:12.9-23.1)months,respectively.The objective response rate(ORR)was 42.3%(11/26),and the disease-control rate was76.9%(20/26).In the subgroup analysis,HR+patients compared with HR-negative patients had significantly improved mPFS of 7.0(95%CI:2.2-11.8)months vs.2.3(95%CI:1.2-3.4)months,respectively(P=0.001);and mPFS in patients without or with chest wall radiotherapy was 6.4(95%CI:1.6-19.5)months vs.3.0(95%CI:1.3-4.6)months,respectively(P=0.041).In the multivariate analysis,HR+status was the only independent predictive factor for favorable PFS(P=0.014).Conclusions:Apatinib was highly effective for BC patients with CWM,especially when combined with endocrine therapy.PFS improved significantly in patients with HR+status who did not receive chest wall radiotherapy.However,adverse events were serious and should be carefully monitored from the beginning of apatinib treatment.Huiping Li Cuizhi Geng Hongmei Zhao Hanfang Jiang Guohong Song Jiayang Zhang Yaxin Liu Xinyu Gui Jing Wang Kun Li Zhongsheng Tong Fangyuan Zhao Junlan Yang Guoliang Chen Qianyu Liu Xu Liang 2021Chinese Journal of Cancer Research2021,33,2:4
7Dietary fatty acids in gut health: Absorption, metabolism and function显示文摘In biological responses,fatty acids(FA)are absorbed and metabolized in the form of substrates for energy production.The molecular structures(number of double bonds and chain length)and composition of dietary FA impact digestion,absorption and metabolism,and the biological roles of FA.Recently,increasing evidence indicates that FA are essentially utilized as an energy source and are signaling molecules that exert physiological activity of gut microbiota and immune responses.In addition,FA could serve as natural ligands for orphan G protein-coupled receptors(GPCR),also called free fatty acid receptors(FFAR),which intertwine metabolic and immune systems via multiple mechanisms.The present review explores the recent findings on FA absorption and its impact on gut health,particularly addressing the mechanism by which dietary FA potentially influences intestinal microbiota and epithelial functions.Also,this work attempts to uncover research ideas for devising future strategies for manipulating the composition of dietary FA to regulate gut health and support a normal immune system for metabolic and immune disorders.E.Xu Chao Chen Jie Fu Luoyi Zhu Junlan Shu Mingliang Jin Yizhen Wang Xin Zong 2021Animal Nutrition2021,,4:4
8Knowledge Graph Completion Based on GCN of Multi-Information Fusion and High-Dimensional Structure Analysis Weight显示文摘Knowledge graph completion(KGC)can solve the problem of data sparsity in the knowledge graph.A large number of models for the KGC task have been proposed in recent years.However,the underutilisation of the structure information around nodes is one of the main problems of the previous KGC model,which leads to relatively single encoding information.To this end,a new KGC model that encodes and decodes the feature information is proposed.First,we adopt the subgraph sampling method to extract node structure.Moreover,the graph convolutional network(GCN)introduced the channel attention convolution encode node structure features and represent them in matrix form to fully mine the node feature information.Eventually,the high-dimensional structure analysis weight decodes the encoded matrix embeddings and then constructs the scoring function.The experimental results show that the model performs well on the datasets used.NIU Haoran HE Haitao FENG Jianzhou NIE Junlan ZHANG Yangsen REN Jiadong 2022Chinese Journal of Electronics2022,31,2:3
9The clinical and genetic characteristics in children with mitochondrial disease in China显示文摘Mitochondrial disease was a clinically and genetically heterogeneous group of diseases, thus the diagnosis was very difficult to clinicians. Our objective was to analyze clinical and genetic characteristics of children with mitochondrial disease in China. We tested 141 candidate patients who have been suspected of mitochondrial disorders by using targeted next-generation sequencing(NGS), and summarized the clinical and genetic data of gene confirmed cases from Neurology Department, Beijing Children's Hospital, Capital Medical University from October 2012 to January 2015. In our study, 40 cases of gene confirmed mitochondrial disease including eight kinds of mitochondrial disease, among which Leigh syndrome was identified to be the most common type, followed by mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes(MELAS). The age-of-onset varies among mitochondrial disease, but early onset was common. All of 40 cases were gene confirmed, among which 25 cases(62.5%)with mitochondrial DNA(mtDNA) mutation, and 15 cases(37.5%) with nuclear DNA(nDNA) mutation. M.3243A>G(n=7)accounts for a large proportion of mtDNA mutation. The nDNA mutations include SURF1(n=7),PDHA1(n=2),and NDUFV1,NDUFAF6, SUCLA2, SUCLG1, RRM2 B, and C12orf65, respectively.Fang Fang Zhimei Liu Hezhi Fang Jian Wu Danmin Shen Suzhen Sun Changhong Ding Tongli Han Yun Wu Junlan Lv Lei Yang Shufang Li Jianxin Lv Ying Shen 2017Science China(Life Sciences)2017,60,7:2

20Inhibition of aberrant Hif1αactivation delays intervertebral disc degeneration in adult mice显示文摘The intervertebral disc(IVD) is the largest avascular tissue. Hypoxia-inducible factors(HIFs) play essential roles in regulating cellular adaptation in the IVD under physiological conditions. Disc degeneration disease(DDD) is one of the leading causes of disability, and current therapies are ineffective. This study sought to explore the role of HIFs in DDD pathogenesis in mice. The findings of this study showed that among HIF family members, Hif1α was significantly upregulated in cartilaginous endplate(EP) and annulus fibrosus(AF) tissues from human DDD patients and two mouse models of DDD compared with controls. Conditional deletion of the E3 ubiquitin ligase Vhl in EP and AF tissues of adult mice resulted in upregulated Hif1α expression and age-dependent IVD degeneration. Aberrant Hif1α activation enhanced glycolytic metabolism and suppressed mitochondrial function. On the other hand, genetic ablation of the Hif1α gene delayed DDD pathogenesis in Vhl-deficient mice. Administration of 2-methoxyestradiol(2ME2), a selective Hif1α inhibitor, attenuated experimental IVD degeneration in mice. The findings of this study show that aberrant Hif1α activation in EP and AF tissues induces pathological changes in DDD, implying that inhibition of aberrant Hif1α activity is a potential therapeutic strategy for DDD.Zuqiang Wang Hangang Chen Qiaoyan Tan Junlan Huang Siru Zhou Fengtao Luo Dali Zhang Jing Yang Can Li Bo Chen Xianding Sun Liang Kuang Wanling Jiang Zhenhong Ni Quan Wang Shuai Chen Xiaolan Du Di Chen Chuxia Deng Liangjun Yin Lin Chen Yangli Xie 2022Bone Research2022,10,1:1
