2CXCL5/CXCR2 axis in tumor microenvironment as potential diagnostic biomarker and therapeutic target显示文摘The components of the tumor microenvironment(TME)in solid tumors,especially chemokines,are currently attracting much attention from scientists.C-X-C motif chemokine ligand 5(CXCL5)is one of the important chemokines in TME.Over-expression of CXCL5 is closely related to the survival time,recurrence and metasta-sis of cancer patients.In TME,CXCL5 binds to its receptors,such as C-X-C motif chemokine receptor 2(CXCR2),to participate in the recruitment of immune cells and promote angiogenesis,tumor growth,and metastasis.The CXCL5/CXCR2 axis can act as a bridge between tumor cells and host cells in TME.Blocking the trans-mission of CXCL5/CXCR2 signals can increase the sensitivity and effectiveness of immunotherapy and slow down tumor progression.CXCL5 and CXCR2 are also regarded as biomarkers for predicting prognosis and molecular targets for customiz-ing the treatment.In this review,we summarized the current literature regarding the biological functions and clinical significance of CXCL5/CXCR2 axis in TME.The possibility to use CXCL5 and CXCR2 as potential prognostic biomarkers and thera-peutic targets in cancer is also discussed.Wen Zhang Huishan Wang Mingyang Sun Xueting Deng Xueru Wu Yilan Ma Mengjing Li Said Maisam Shuoa Qiang You Lin Miao 2020Cancer Communications2020,40,2:19
3Heyan Kuntai capsule versus dehydroepiandrosterone in treating Chinese patients with infertility caused by diminished ovarian reserve: a multicenter, randomized controlled trial显示文摘OBJECTIVE: To evaluate the clinical efficacy and safety of Heyan Kuntai capsule(HYKT) in treating women with infertility caused by diminished ovarian reserve(DOR).METHODS: One hundred eight eligible patientsfrom three Chinese hospitals were randomly divided into an HYKT treatment group(n = 55) or a dehydroepiandrosterone(DHEA) treatment group(n =53). Patients in the HYKT group were treated orally with four 0.5 g HYKT three times a day; patients in the DHEA group were treated with one 25.0 mg DHEA capsule three times a day. All patients were treated for 3 months and followed up over a3-month period.RESULTS: Of 108 patients, 12 dropped out: six from the HYKT group, and six from the DHEA group. Eleven patients got pregnant during the treatment. Serum anti-Müllerian hormone levels and antral follicle counts increased significantly in both groups after treatment(P < 0.05) especially in the HYKT group(P < 0.05). Serum follicle stimulating hormone(FSH) levels and FSH/luteinizing hormone ratios decreased(P < 0.05) with no significant difference between the two groups. Estradiol levels in the HYKT group and DHEA-sulfate levels in the DHEA group both increased(P < 0.05). The spontaneous pregnancy rates were 12% and 11% in the HYKT and DHEA groups, respectively(not significant). During the follow-up period, 16 patients in the HYKT group underwent in vitro fertilization-embryo transfer(IVF-ET) and the number of retrieved oocytes was(5.1 ± 1.8). In DHEA group, 20 patients underwent IVF-ET and the number of retrieved oocyte was(4.2 ± 1.9)(not significant); clinical pregnancy rates were 38% in the HYKT group and 20%in DHEA group(not significant). No significant adverse reactions were observed.CONCLUSION: HYKT can improve the ovarian re-serve and hormone levels in patients with infertility caused by DOR. Pregnancy rates after HYKT treatment were similar to those of DHEA treatment.HYKT might be an alternative to the treatment of infertility caused by DOR.Gao Hui Xia Tian Ma Ruihong Zhao Zhimei Song Xueru Wang Baojuan Liu Lijing Han Kaimei Wang Guoqing Fu Yu Hao Guimin 2017Journal of Traditional Chinese Medicine2017,37,4:14
4Narrow-band radar imaging of spinning targets显示文摘According to the characteristics of narrow-band radar echoes from spinning targets,this paper applies the complex-valued back-projection method to image formation.Since it accumulates the sinusoidal phase of spinning scatterers effectively,this method can obtain high resolution imaging.The resolution and required radar pulse repetition frequency (PRF) of this method are deduced.For imaging of fast spinning targets,however,spurious peaks appear due to azimuth down sampling with a low PRF.Therefore,a signal model of azimuth down-sampled echoes is created according to the compressed sensing (CS) theory.Then an imaging method based on orthogonal matching pursuit (OMP) is proposed according to the sparsity nature of ISAR echoes.Finally,the effectiveness of the proposed methods is demonstrated using simulated data.BAI XueRu SUN GuangCai WU QiSong XING MengDao BAO Zheng 2011Science China(Information Sciences)2011,54,4:9
5The signal pathways and treatment of cytokine storm in COVID-19显示文摘The Coronavirus Disease 2019(COVID-19)pandemic has become a global crisis and is more devastating than any other previous infectious disease.It has affected a significant proportion of the global population both physically and mentally,and destroyed businesses and societies.Current evidence suggested that immunopathology may be responsible for COVID-19 pathogenesis,including lymphopenia,neutrophilia,dysregulation of monocytes and macrophages,reduced or delayed type I interferon(IFN-I)response,antibody-dependent enhancement,and especially,cytokine storm(CS).The CS is characterized by hyperproduction of an array of pro-inflammatory cytokines and is closely associated with poor prognosis.These excessively secreted pro-inflammatory cytokines initiate different inflammatory signaling pathways via their receptors on immune and tissue cells,resulting in complicated medical symptoms including fever,capillary leak syndrome,disseminated intravascular coagulation,acute respiratory distress syndrome,and multiorgan failure,ultimately leading to death in the most severe cases.Therefore,it is clinically important to understand the initiation and signaling pathways of CS to develop more effective treatment strategies for COVID-19.Herein,we discuss the latest developments in the immunopathological characteristics of COVID-19 and focus on CS including the current research status of the different cytokines involved.We also discuss the induction,function,downstream signaling,and existing and potential interventions for targeting these cytokines or related signal pathways.We believe that a comprehensive understanding of CS in COVID-19 will help to develop better strategies to effectively control immunopathology in this disease and other infectious and inflammatory diseases.Lan Yang Xueru Xie Zikun Tu Jinrong Fu Damo Xu Yufeng Zhou 2021Signal Transduction and Targeted Therapy2021,6,8:7
6Spatio-temporal variation of the wet-dry conditions from 1961 to 2015 in China显示文摘As an important part of the regional environment, the wet-dry climate condition is determined by precipitation and potential evapotranspiration(expressed as ETo). Based on weather station data, this study first calculated ETo by using the FAO56Penman-Monteith model. Then, the dryness index K(ratio of ETo to precipitation) was used to study the spatio-temporal variation of the wet-dry condition in China from 1961 to 2015; moreover, dominant climatic factors of the wet-dry condition change were discussed. The annual precipitation and ETo of the Qinling-Huaihe line were close to a balance(K≈1.0). The annual precipitation in most areas exceeded the ETo in the south of this line and the east of Hengduan Mountains(K<1.0), where the climate is wet.Furthermore, the precipitation in the northwest inland areas of China, where the climate is dry, was markedly lower than ETo(K≥4.0). The overall annual K of China fluctuated around the 55-year mean and its linear trend was not significant. However, a relatively wet period of about 10 yr(1987–1996) was recorded. The overall annual K of China showed strong cyclicality on the time scale of 3, 7–8, 11 and 26–28 yr, and regional differences of the annual K trends and cyclicality were large. The degrees of wetness in the Northwest China and western Qinghai-Tibet Plateau were substantially increased, whereas the degrees of dryness in the Yunnan-Guizhou Plateau, Sichuan Basin, and Loess Plateau were markedly increased. The linear trend of the annual K in most regions of China was not significant, and the annual K of most areas in China showed strong cyclicality on the 8–14 yr time scale.Precipitation was the dominant factor of wet-dry condition change in most areas, especially in North China, where the annual K change was highly correlated with precipitation.YUAN QuanZhi WU ShaoHong DAI ErFu ZHAO DongSheng ZHANG XueRu REN Ping 2017Science China Earth Sciences2017,60,11:6
7The influence of urban park characteristics on bird diversity in Nanjing, China显示文摘Background:Habitat loss,fragmentation and decrease of habitat quality caused by urbanization have led to a dramatic decline in biodiversity worldwide.For highly urbanized areas,parks have become“islands”or habitat fragments for wildlife.As an important indicator group of urban ecosystem health,the response of birds to urbanization has attracted the global attention of ecologists.Understanding the key factors affecting bird diversity in urbanized environment is crucial to the protection of biodiversity in urban ecosystems.Methods:We used the line-transect method to survey birds in 37 urban parks in Nanjing,China.We also measured a number of park characteristics(area,isolation,shape index,environmental noise,distance to city center,and habitat diversity)that are commonly assumed to influence bird diversity.We then used the information-theoretic multi-model inference approach to determine which park characteristics had significant impacts on bird species richness.Results:We found that park area,habitat diversity and the distance to city center were the best positive predictors of bird species richness in Nanjing urban parks.By contrast,park isolation,park shape and environmental noise had little or no influence on bird diversity.Conclusions:Our study highlights the importance of park area,habitat diversity and the distance to city center in determining bird diversity in Nanjing city parks.Therefore,from a conservation viewpoint,we recommend that large parks with complex and diverse habitats far away from the city center should be retained or constructed to increase bird diversity in urban design and planning.Xueru Yang Xinwei Tan Chuanwu Chen Yanping Wang 2020Avian Research2020,11,4:5

9Highly active N-doped carbon encapsulated Pd-Fe intermetallic nanoparticles for the oxygen reduction reaction显示文摘Developing highly efficient non-R catalysts for fuel cells and metal-air batteries is highly desirable but still challenging due to the sluggish oxygen reduction reaction(ORR).Herein,a facile and efficient strategy is demonstrated to prepare N-doped carbon encapsulated ordered Pd-Fe intermetallic(O-Pd-Fe@NC/C)nanoparticles via a one-step thermal annealing method.The obtained O-Pd-Fe@NC/C nanoparticles show enhanced ORR activity,durability and anti-poisoning capacity in both acid and alkaline medium.When O-Pd-Fe@NC/C serving as cathode catalyst for Zn-air battery,it exhibits higher voltage platform and superior cycling performance with respect to the Zn-air battery based on the mixture of Pt/C and Ir/C catalysts.The enhanced electrocatalytic performance can be ascribed to the formation of face-centered tetragonal(fct)Pd-Fe nanoparticles,the protective action of the N-doped carbon layer and the interface confinement effect between them.The in situ formed N-doped carbon shell not only restrains the Pd-Fe ordered intermetallics from aggregating effectively during the thermal annealing process,but also provides a strong anchoring effect to avoid the detachment of Pd-Fe nanoparticles from the carbon support during the potential cycling.This facile carbon encapsulation strategy may also be extended to the preparation of a wide variety of N-doped carbon encapsulated intermetallic compounds for fuel cell application.Yezhou Hu Yun Lu Xueru Zhao Tao Shen Tonghui Zhao Mingxing Gong Ke Chen Chenglong Lai Jian Zhang Huolin L.Xin Deli Wang 2020Nano Research2020,13,9:3
10One step method of structure engineering porous graphitic carbon nitride for efficient visible-light photocatalytic reduction of Cr(Ⅵ)显示文摘Porous g-C_(3)N_(4)nanosheets(PCN)were prepared by the nickel-assisted one-step thermal polymerization method.Hydrogen(H2)which was produced by the reaction between nickel(Ni)foam and ammonia(NH3)defined the structure and properties of PCN.During the formation of PCN,the participation of H2 not only enhanced the spacing between layers but also boosted the specific surface area that more active sites were exposed.Additionally,H2 promoted pores formation in the nanosheets,which was beneficial to the transfer of photons through lamellar structure and improved the absorption efficiency of visible light.Remarkably,the obtained PCN possessed better Cr(Ⅵ)photocatalytic reduction efficiency than pure g-C_(3)N_(4).The reaction rate constant(k)of PCN(0.013 min-1)was approximately twice that of bare g-C_(3)N_(4)(0.007 min-1).Furthermore,the effects of original pH and concentration of Cr(Ⅵ)-containing solution on re moval efficiency of Cr(Ⅵ)were explored.A possible photocatalytic mecha nism was proposed based on the experiments of radical scavengers and photoelectrochemical characterizations.Xueru Chen Yin Zhang Dashui Yuan Wu Huang Jing Ding Hui Wan Wei-Lin Dai Guofeng Guan 2021Journal of Materials Science & Technology2021,,12:3
11Management Algorithm for Prevention of Mother-to-child Transmission of Hepatitis B Virus(2022)显示文摘The World Health Organization(WHO)has set the goal of eliminating hepatitis as a threat to public health by 2030.Blocking mother-to-child transmission(MTCT)of hepatitis B virus(HBV)is not only the key to eliminating viral hepatitis,but also a hot issue in the field of hepatitis B prevention and treatment.To standardize the clinical management of preventing MTCT of HBV and achieve zero HBV infection among infants,the Chinese Foundation for Hepatitis Prevention and Control organized experts to compile a management algorithm for prevention of MTCT of HBV based on the latest research progress and guidelines,including 10 steps of pregnancy management and postpartum follow-up,among which screening,antiviral treatment,and infant immunization are its core components.Zhihua Liu Zhongdan Chen Fuqiang Cui Yang Ding Yunfei Gao Guorong Han Jidong Jia Jie Li Zengde Li Yingxia Liu Qing Mao Ailing Wang Wei Wang Lai Wei Jianhong Xia Qing Xie Xizhong Yang Xueru Yin Hua Zhang Liaoyun Zhang Wenhong Zhang Hui Zhuang Xiaoguang Dou Jinlin Hou 2022Journal of Clinical and Translational Hepatology2022,10,5:2
12Nestedness and underlying processes of bird assemblages in Nanjing urban parks显示文摘Nestedness is an important pattern frequently reported for species assemblages on islands or fragmented systems.However,to date,there are few studies that comprehensively investigated faunal nestedness and underlying processes in urbanized landscapes.In this study,we examined the nestedness of bird assemblages and its underlying causal mechanisms in 37 urban parks in Nanjing,China.We used the line-transect method to survey birds from April 2019 to January 2020.We used the Weighted Nestedness metric based on Overlap and Decreasing Fill(WNODF)to estimate the nestedness of bird assemblages.We applied spearman partial correlation test to examine the relationships between nestedness ranks of sites and park characteristics(area,isolation,anthropogenic noise,number of habitat types,and building index),as well as between nestedness ranks of species and their ecological traits(body size,geographic range size,clutch size,minimum area requirement,dispersal ratio,and habitat specificity).We found that bird assemblages in urban parks were significantly nested.Park area,habitat diversity,building index,habitat specificity,and minimum area requirement of birds were significantly correlated with nestedness.Therefore,the nestedness of bird assemblages was caused by selective extinction,habitat nestedness,and urbanization.However,the nestedness of bird assemblages did not result from passive sampling,selective colonization,or human disturbance.Overall,to maximize the number of species preserved in our system,conservation priority should be given to parks with large area,rich habitat diversity,and less building index.From a species perspective,we should focus on species with large area requirement and high habitat specificity for their effective conservation.Xinwei Tan Xueru Yang Chuanwu Chen Yanping Wang 2021Current Zoology2021,67,4:2
13One-step fabrication of nitrogen-deficient carbon nitride through pyrolysis of melamine and 1,2,4-triazole for its enhanced photocatalytic degradation显示文摘The construction of defects in semiconductor photocatalysts,as a kind of modification methods,plays an indispensable role in the enhancement of the photocatalytic performance.Herein,nitrogen defects were successfully introduced into the framework of graphite carbon nitride(CN-T_(x))through thermal polymerization with melamine and 1,2,4-triazole as precursors.The existence of nitrogen defects in CN-T_(x) were confirmed to be located at the two-coordinated(N_(2c))C■N-C lattice sites,which resulted in the destruction of its planar structure and the initiation of n-π^(*)electron transition that greatly expanded the response range to visible light and improved the separation efficiency of photogenerated charge carrier.More significantly,CN-T_(x) could enhance photocatalytic water purification activity towards different kinds of pollutants.The photocatalytic rates of CN-T_(3) were estimated to be 2.54(tetracycline)and 2.31(2-hydroxynaphthalene)times higher than those of pristine g-C3N4.Furthermore,the possible photocatalytic degradation mechanism over CN-T_(x) photocatalyst was proposed by free radical trapping experiments combined with ERS characterization.This work provides an in-depth understanding of the important role of nitrogen defects in the electronic structure and chemical properties of g-C3N4 and its photocatalytic water purification performance.Jing Ding Zongyuan Li Xueru Chen Yiwei Jiao Dashui Yuan Wei Du Hui Wan Guofeng Guan 2021Green Chemical Engineering2021,2,3:1
14Temperature‑Arousing Self‑Powered Fire Warning E‑Textile Based on p-n Segment Coaxial Aerogel Fibers for Active Fire Protection in Firefighting Clothing显示文摘Firefighting protective clothing is a crucial protective equipment for firefighters to minimize skin burn and ensure safety firefighting operation and rescue mission.A recent increasing concern is to develop self-powered fire warning materials that can be incorporated into the firefighting clothing to achieve active fire protection for firefighters before the protective clothing catches fire on fireground.However,it is still a challenge to facilely design and manufacture thermoelectric(TE)textile(TET)-based fire warning electronics with dynamic surface conformability and breathability.Here,we develop an alternate coaxial wet-spinning strategy to continuously produce alternating p/n-type TE aerogel fibers involving n-type Ti_(3)C_(2)T_(x)MXene and p-type MXene/SWCNT-COOH as core materials,and tough aramid nanofiber as protective shell,which simultaneously ensure the flexibility and high-efficiency TE power generation.With such alternating p/n-type TE fibers,TET-based self-powered fire warning sensors with high mechanical stability and wearability are successfully fabricated through stitching the alternating p-n segment TE fibers into aramid fabric.The results indicate that TET-based fire warning electronics containing 50 p-n pairs produce the open-circuit voltage of 7.5 mV with a power density of 119.79 nW cm-2 at a temperature difference of 300℃.The output voltage signal is then calculated as corresponding surface temperature of firefighting clothing based on a linear relationship between TE voltage and temperature.The fire alarm response time and flame-retardant properties are further displayed.Such self-powered fire warning electronics are true textiles that offer breathability and compatibility with body movement,demonstrating their potential application in firefighting clothing.Hualing He Yi Qin Zhenyu Zhu Qing Jiang Shengnan Ouyang Yuhang Wan Xueru Qu Jie Xu Zhicai Yu 2023Nano-Micro Letters2023,15,12:1
