| 1 | Accuracy of triage strategies for human papillomavirus DNA-positive women in low-resource settings:A cross-sectional study in China显示文摘Objective: Care HPV is a human papillomavirus(HPV) DNA test for low-resource settings(LRS).This study assesses optimum triage strategies for care HPV-positive women in LRS.Methods: A total of 2,530 Chinese women were concurrently screened for cervical cancer with visual inspection with acetic acid(VIA),liquid-based cytology and HPV testing by physician-and self-collected care HPV,and physician-collected Hybrid Capture 2(HC2).Screen-positive women were referred to colposcopy with biopsy and endocervical curettage as necessary.HPV-positivity was defined as ≥1.0 relative light units/cutoff(RLU/CO) for both care HPV and HC2.Primary physician-HC2,physician-care HPV and self-care HPV and in sequential screening with cytology,VIA,or increased HPV test-positivity performance,stratified by age,were assessed for cervical intraepithelial neoplasia(CIN) grade 2/3 or worse(CIN2/3+) detection.Results: The sensitivities and specificities of primary HPV testing for CIN2+ were: 83.8%,88.1% for physiciancare HPV; 72.1%,88.2% for self-care HPV; and 97.1%,86.0% for HC2.Physician-care HPV test-positive women with VIA triage had a sensitivity of 30.9% for CIN2+ versus 80.9% with cytology triage.Self-care HPV testpositive women with VIA triage was 26.5% versus 66.2% with cytology triage.The sensitivity of HC2 test-positive women with VIA triage was 38.2% versus 92.6% with cytology triage.The sensitivity of physician-care HPV testing for CIN2+ decreased from 83.8% at ≥1.0 RLU/CO to 72.1% at ≥10.00 RLU/CO,while the sensitivity of selfcare HPV testing decreased from 72.1% at ≥1.0 RLU/CO to 32.4% at ≥10.00 RLU/CO; similar trends were seen with age-stratification.Conclusions: VIA and cytology triage improved specificity for CIN2/3 than no triage.Sensitivity with VIA triage was unsuitable for a mass-screening program.VIA provider training might improve this strategy.Cytology triage could be feasible where a high-quality cytology program exists.Triage of HPV test-positive women by increased test positivity cutoff adds another LRS triage option. | Margaret Wang Shangying Hu Shuang Zha o Wenhua Zhang Qinjing Pan Xun Zhang FengChen Jinxiu Han Junfei Ma Jennifer S.Smith Youlin Qiao Caihong Zhou Fanghui Zhao | 2017 | Chinese Journal of Cancer Research2017，29，6： | 6 |
| 2 | Development of high-resolution chloroplast markers for intraspecific phylogeographic studies of Phaeocystis globosa显示文摘Phaeocystis globosa is an important harmful algal bloom causative species distributing widely in temperate and tropical coastal waters in the world.The morphological,physiological,and biochemical characteristics are different among geographic strains,which can not be distinguished with nuclear ribosomal DNA markers at present.Therefore,the genetic distance and phylogeographic relationships of nuclear 28S rDNA D1–D2 and ITS regions,and three chloroplast intergenic spacers(petN-trnS1,trnM1-psbA,and rbcS-rpl27)were analyzed and compared among 13 strains of P.globosa isolated from the Pacific Ocean and Atlantic Ocean in this study.In addition,the nucleotide polymorphisms of 28S rDNA D1–D2,ITS,and rbcS-rpl27 regions were evaluated in two P.globosa strains.The various levels of nucleotide polymorphism were in the nuclear 28S rDNA D1–D2 region and ITS region,but no polymorphism was in the chloroplast rbcS-rpl27 intergenic spacer.A reasonable intraspecific phylogeographic relationship was presented by rbcS-rpl27 intergenic spacer,which had the strongest distinction to geographic strains compared to those of 28S rDNA D1–D2 and ITS regions.In the phylogenetic tree of rbcS-rpl27 intergenic spacer,the two strains from the North Sea of the Atlantic Ocean were divided firstly from the species of P.globosa,and then formed an independent clade,while the other Atlantic strains and all of Pacific strains joined up to build the other clade.It was implied that at least two genetically distant populations of P.globosa existed in the Atlantic coastal regions.This study provided a high-resolution chloroplast marker to analyze intraspecific phylogeographic populations of P.globosa,and preliminarily clarified the genetic relationships of the Pacific and Atlantic strains of P.globosa. | Qingchun ZHANG Zhuang NIU Jinxiu WANG Chao LIU Fanzhou KONG Xiaokun HU Jiayu ZHAO Rencheng YU | 2021 | Journal of Oceanology and Limnology2021，39，2： | 3 |
| 3 | Identifying human body states by using a flexible integrated sensor显示文摘Flexible sensors are required to be lightweight,compatible with the skin,sufficiently sensitive,and easily integrated to extract various kinds of body vital signs during continuous healthcare monitoring in daily life.For this,a simple and low-cost flexible temperature and force sensor that uses only two carbon fiber beams as the sensing layer is reported in this work.This simple,flexible sensor can not only monitor skin temperature changes in real time but can also extract most pulse waves,including venous waves,from most parts of the human body.A pulse diagnostic glove containing three such flexible sensors was designed to simulate pulse diagnostic methods used in traditional Chinese medicine.Wearable equipment was also designed in which four flexible sensors were fixed onto different body parts(neck,chest,armpit,and fingertip)to simultaneously monitor body temperature,carotid pulse,fingertip artery pulse,and respiratory rate.Four important physiological indicators—body temperature(BT),blood pressure(BP),heart rate(HR),and respiratory rate(RR)—were extracted by the wearable equipment and analyzed to identify exercise,excited,tired,angry,and frightened body states. | Ying Jin Guoning Chen Kete Lao Songhui Li Yong Lu Yufeng Gan Zhundong Li Jiajia Hu Jingcheng Huang Jinxiu Wen Honggui Deng Min Yang Zhiming Chen Xiaoyan Hu Baowen Liang Jianyi Luo | 2020 | npj Flexible Electronics2020，4，1： | 2 |

| 5 | Effects of fasting and refeeding on expression of MAFbx and MuRF1 in chick skeletal muscle显示文摘The present study investigated the effects of fasting and refeeding on the expression of proteasome-related genes and their downstream targets in the skeletal muscles of chicks.Seven-day-old chicks were fasted for 24 or 48 h and then refed for 4 h.The expression levels of MAFbx and MuRF1,which function as E3 ligases in the ubiquitin-proteasome system,were investigated at the mRNA and protein levels.MAFbx and MuRF1 expression were increased by fasting and these increases were downregulated by refeeding.The expression of the target proteins of these E3 ligases,MyoD and M-CK,was also analyzed.The levels of these proteins were downregulated by fasting,and these decreases were rescued by refeeding.The results of this study indicate that fasting stimulates MAFbx and MuRF1 expression in chicks,possibly leading to increased degradation of their corresponding target proteins. | LI QingHe LI JinXiu LAN He WANG Nan HU XiaoXiang CHEN Li LI Ning | 2011 | Science China(Life Sciences)2011，54，10： | 1 |
| 6 | Colonization and development of the gut microbiome in calves显示文摘Colonization and development of the gut microbiome are crucial for the growth and health of calves.In this review,we summarized the colonization,beneficial nutrition,immune function of gut microbiota,function of the gut barrier,and the evolution of core microbiota in the gut of calves of different ages.Homeostasis of gut microbiome is beneficial for nutritional and immune system development of calves.Disruption of the gut microbiome leads to digestive diseases in calves,such as diarrhea and intestinal inflammation.Microbiota already exists in the gut of calf fetuses,and the colonization of microbiota continues to change dynamically under the influence of various factors,which include probiotics,diet,age,and genotype.Colonization depends on the interaction between the gut microbiota and the immune system of calves.The abundance and diversity of these commensal microbiota stabilize and play a critical role in the health of calves. | Yufeng Du Ya Gao Mingyang Hu Jinxiu Hou Linhai Yang Xianghuang Wang Wenjuan Du Jianxin Liu Qingbiao Xu | 2023 | Journal of Animal Science and Biotechnology2023，14，4： | 1 |
| 7 | Newly recorded bloom-forming dinoflagellate Gymnodinium impudicum in Haizhou Bay,Yellow Sea,China显示文摘With the development of industrialization and aquaculture in Jiangsu and Shandong Provinces along the South Yellow Sea coast,China,eutrophication has greatly intensified in the region,resulting in frequent occurrence of diverse harmful algal blooms.An algal bloom formed by a chain-forming dinofl agellate species was recorded in the Haizhou Bay,South Yellow Sea,in September 2020.The causative species was isolated and studied in morphology,molecular phylogeny,pigment profile,presence of paralytic shellfish toxins,and acute toxicity.The loop-shaped apical groove running anticlockwise around the apex,the presence of peridinin as characteristic pigment,as well as a single phylogenic clade of 28S ribosomal DNA(100%posterior probability),defined this species as Gymnodinium impudicum,a non-toxic species that exhibited no obvious biotoxicity to the rotifer Brachionus plicatilis,the copepod Artemia salina,and the shrimp Neomysis awatschensis.Gymnodinium impudicum is typically distributed in coastal waters with high nitrate concentrations,where it reaches a maximum density of 2.6×10~5 cells/L.This is the first report of a G.impudicum bloom in the Yellow Sea;however,G.impudicum blooms may have been misidentified or underreported in Haizhou Bay due to the species morphological similarity with G.catenatum.A combination of multiple methods is recommended to accurately identify new algal bloom species. | Jinxiu WANG Fanzhou KONG Yunfeng WANG Nanjing JI Minjie SONG Zhangxi HU Zhuang NIU Chao LIU Xin WANG Yuanyuan SUN Rencheng YU Tian YAN | 2022 | Journal of Oceanology and Limnology2022，40，6： | 1 |

| 9 | Tailoring impedance match and enhancing microwave absorption of Fe_3O_4/Bi_(24)Fe_2O_(39)/Bi hollow porous microrods by controlling their composition显示文摘A self-assembly/precipitate conversion/decomposition process was developed for the controllable synthesis of Fe_3O_4/Bi_(24)Fe_2O_(39)/Bi hollow porous microrods(HPMRs).The results demonstrated that the crystal size,component,and performances of HPMRs could be effectively modulated via changing Fe^(2+)/Bi^(3+)molar ratio(γ).Fe_3O_4/Bi_(24)Fe_2O_(39)/Bi HPMRs exhibited ferromagnetic behavior at room temperature.As Bi and Bi_(24)Fe_2O_(39)contents increased withγ,the saturation magnetization M_sand attenuation constantly decreased,whereas coercivity H_cand impedance matching ratio increased.Compounding Fe_3O_4with small quantities of Bi and Bi_(24)Fe_2O_(39)into HPMRs can significantly enhance microwave absorption.Fe_3O_4/Bi_(24)Fe_2O_(39)/Bi HPMRs formed atγ=1:0.25 exhibited the optimum microwave absorption performance.The minimum R_Lwas-47.3 dB at8.72 GHz,corresponding to 2.4 mm sample thickness.The absorption band with the reflection loss below-20 dB was up to 14.0 GHz for the absorber with a thickness of 1.4-8.0 mm.The results demonstrate that the introduction of electromagnetic transparent materials(Bi_(24)Fe_2O_(39)or Bi)can improve the microwave absorption performances of Fe_3O_4 composites owing to enhanced impedance matching rather than attenuation constant. | Lin Liu Na He Jiacheng Sun Panbing Hu Rujia He Jinxiu Cheng Weifu Tian Guoxiu Tong | 2018 | Progress in Natural Science:Materials International2018，28，5： | 0 |
| 10 | Mesenchymal stromal/stem cells:breaking the deadlock in the treatment of multiple organ dysfunction syndrome显示文摘Multiple organ dysfunction syndrome(MODS)is a clinical syndrome characterized by the dysfunction of two or more systems or organs.This internal environment disorder occurs simultaneously 24 h after severe trauma,shock,or infection.MODS has a high fatality rate ranging from 20%to 100%.[1]In the development of MODS following severe trauma or infection,multiple organ system fail sequentially,involving the lungs,kidneys,liver,cardiovascular,central nervous system,gastrointestinal,immune,and the blood coagulation system.MODS has complex pathogenic factors,and there are four main pathogenesis hypotheses:(1)uncontrolled inflammation hypothesis,(2)ischemia–reperfusion injury,(3)the gastrointestinal hypothesis,and(4)the biphasic preexcitation theory.Although the current clinical treatment methods of MODS,such as inflammatory factor antibodies,highly effective anti-coagulants,renal function replacement therapy,and other treatment methods,have been improved continuously,their effectiveness in MODS treatment is not ideal.Therefore,clinical MODS treatment is faced with great challenges[Figure 1]. | Jinxiu Hu Ye Li Jie He Xiaojuan Zhao Mengdie Chen Li Ye Xinghua Pan | 2022 | Chinese Medical Journal2022，135，23： | 0 |
| 11 | Reviving and characterizing three species of dinoflagellate cysts dormant for about 70 years in the East China Sea:Biecheleria brevisulcata,Biecheleriopsis adriatica,and Scrippsiella donghaienis显示文摘Many marine dinoflagellates can form resting cysts as a part of their life cycle,and the cysts could be buried in sediment and remained viable for as long as over 150 years.However,only a very limited number of cyst species have been revived from long-buried sediments and investigated in regard to a possible shift in the intra-specific genetic structure of a species detected from the historical record at a particular location.Here,we report a successful germination of three species of resting cysts that were sampled from the depth dated back to 1941±18 AD from a 44-cm sediment core from the East China Sea.Seven isolates were established from germination of single cyst isolation or multi-cyst germinations.LSU rRNA gene or ITS sequences of these strains were obtained,then they were identified to be Biecheleria brevisulcata(five strains),Biecheleriopsis adriatica(one strain),and Scrippsiella donghaienis(one strain)in terms of morphology and rRNA gene sequence.Biecheleria brevisulcata strain 1,Bps.adriatica strain 21,and S.donghaienis strain 23 were examined in detail with light microscope(LM)and scanning electron microscope(SEM),and analyzed with high performance liquid chromatography(HPLC)for their pigment compositions,and genetic diversity.We also confirmed the presence of a resting cyst of Bps.adriatica in the field for the first time.The LSU rRNA gene-based genetic distances of Bps.adriatica from that obtained from water sample,single-cell PCR sequencing for the cysts isolated from the surface sediment of the same sea area and that reported from other regions during the recent years,and ITS-based genetic distances of S.donghaienis from that obtained from cysts isolated from the surface sediment of the same location and that reported from other regions during the recent years indicated that the intra-specific genetic structure of each species in the sampling area may have shifted during the last 70 years.Our work confirms that B.brevisulcata,Bps.adriatica,and S.donghaienis,all described as new species around 2010,have inhabited the East China Sea for about 70 years.The present work reports for the first time the revival of dinoflagellate resting cysts long-buried in the coastal sediments of China,which facilitates further study on the historical occurrences of other harmful dinoflagellates and their relevance to the regional climate and environmental changes in China. | Zhangxi HU Xiaoying SONG Jinxiu WANG Zhe TAO Yuanyuan SUN Yuhang LI Yuyang LIU Yunyan DENG Lixia SHANG Zhaoyang CHAI Yingzhong TANG | 2022 | Journal of Oceanology and Limnology2022，40，6： | 0 |
| 12 | Fiber-junction design for directional bending sensors显示文摘Flexible sensors in wearable electronics have become increasingly multifunctional due to the development of materials synthesis and structure design.In particular,structural design can not only add capabilities to sensors fabricated from existing available and normal materials,but also offer opportunities for the fabrication of sensors with certain desired functions.Here,we designed a series of fiber-junction structure models,in which two fibers were simply hooked to each other to form a junction on a flexible printed circuit,for fabrication of directional bending sensors.The value and direction of bending angle are related to the change in electronic signal by a theoretical expression,allowing us to employ a simple and practicable method to use available conductive fiber materials to fabricate high-sensitivity,high-resolution and directional bending sensors.In addition,these models are generally applicable,which have broad combination with different conductive fiber,and corresponding bending sensors all possess capability of directional identification.Furthermore,the capability of identifying directional bending was demonstrated by human motion monitoring such as joint bending and muscle contraction. | Zhundong Li Fengming Hu Zhiming Chen Jingcheng Huang Guoning Chen Runbo Chen Minmin Wei Kete Lao Jiajia Hu Jintao Zheng Lvfei Wang Yuan Yao Xiaoyan Hu Baowen Liang Min Yang Xihong Lu Jinxiu Wen Jianyi Luo | 2021 | npj Flexible Electronics2021，5，1： | 0 |
