| 1 | Circulating tumor cells:biology and clinical significance显示文摘Circulating tumor cells(CTCs)are tumor cells that have sloughed off the primary tumor and extravasate into and circulate in the blood.Understanding of the metastatic cascade of CTCs has tremendous potential for the identification of targets against cancer metastasis.Detecting these very rare CTCs among the massive blood cells is challenging.However,emerging technologies for CTCs detection have profoundly contributed to deepening investigation into the biology of CTCs and have facilitated their clinical application.Current technologies for the detection of CTCs are summarized herein,together with their advantages and disadvantages.The detection of CTCs is usually dependent on molecular markers,with the epithelial cell adhesion molecule being the most widely used,although molecular markers vary between different types of cancer.Properties associated with epithelial-tomesenchymal transition and stemness have been identified in CTCs,indicating their increased metastatic capacity.Only a small proportion of CTCs can survive and eventually initiate metastases,suggesting that an interaction and modulation between CTCs and the hostile blood microenvironment is essential for CTC metastasis.Single-cell sequencing of CTCs has been extensively investigated,and has enabled researchers to reveal the genome and transcriptome of CTCs.Herein,we also review the clinical applications of CTCs,especially for monitoring response to cancer treatment and in evaluating prognosis.Hence,CTCs have and will continue to contribute to providing significant insights into metastatic processes and will open new avenues for useful clinical applications. | Danfeng Lin Lesang Shen Meng Luo Kun Zhang Jinfan Li Qi Yang Fangfang Zhu Dan Zhou Shu Zheng Yiding Chen Jiaojiao Zhou | 2021 | Signal Transduction and Targeted Therapy2021，6，12： | 8 |
| 2 | Application of fluorescence in situ hybridization in the detection of bladder transitional-cell carcinoma: A multi-center clinical study based on Chinese population显示文摘Objective:To evaluate the diagnostic value of fluorescence in situ hybridization(FISH)in bladder cancer.Methods:We enrolled healthy volunteers and patients who were clinically suspected to have bladder cancer and conducted FISH tests and cytology examinations from August 2007 to December 2008.Receiver operating characteristic(ROC)curve analysis was performed and the area under curve(AUC)values were calculated for both the FISH and urine cytology tests.Results:A cohort of 988 healthy volunteers was enrolled to establish a reference range for the normal population.A total of 4807 patients with hematuria were prospectively,randomly enrolled for the simultaneous analysis of urine cytology,FISH testing,and a final diagnosis as determined by the pathologic findings of a biopsy or a surgically-excised specimen.Overall,the sensitivity of FISH in detecting transitional-cell carcinoma was 82.7%,while that of cytology was 33.4%(p<0.001).The sensitivity values of FISH for non-muscle invasive and muscle invasive bladder transitional-cell carcinoma were 81.7%and 89.6%,respectively(p=0.004).The sensitivity values of FISH for low and high grade bladder cancer were 82.6%and 90.1%,respectively(p=0.002).Conclusion:FISH is significantly more sensitive than voided urine cytology for detecting bladder cancer in patients evaluated for gross hematuria at all cancer grades and stages.Higher sensitivity using FISH was obtained in high grade and muscle invasive tumors. | Liqun Zhou Kaiwei Yang Xuesong Li Yi Ding Dawei Mu Hanzhong Li Yong Yan Jinyi Li Dongwen Wang Wei Li Yulong Cong Jiangping Gao Kewei Ma Yajun Xiao Sheng Zhang Hongyi Jiang Weilie Hu Qiang Wei Xunbo Jin Zhichen Guan Qingyong Liu Danfeng Xu Xin Gao Yongguang Jiang Weimin Gan Guang Sun Qing Wang Yanhui Liu Jianquan Hou Liping Xie Xishuang Song Fengshuo Jin Jiafu Feng Ming Cai Zhaozhao Liang Jie Zhang Dingwei Ye Lin Qi Lulin Ma Jianzhong Shou Yuping Dai Jianyong Shao Ye Tian Shizhe Hong Tao Xu Chuize Kong Zefeng Kang Yuexin Liu Xun Qu Benkang Shi Shaobin Zheng Yi Lin Shujie Xia Dong Wei Jianbo Wu Weiling Fu Zhiping Wang Jianbo Liang | 2019 | Asian Journal of Urology2019，6，1： | 2 |
| 3 | Synthesis, crystal structure and photocatalytic performance of polyoxometalate K_(13)[Gd(GeW_(11)O_(39))_2]·34H_2O显示文摘A polyoxometalate K_(13)[Gd(GeW_(11)O_(39))_2]·34 H_2 O was synthesized and characterized by elemental analysis,IR spectroscopy, UV spectra, XRD and thermal gravimetric analysis. X-ray single-crystal structural analysis indicates that the title compound crystallizes in the triclinic crystal system. The heteropolyanion of [Gd(GeW_(11)O_(39))_2]^(13) consists of two [GeW_(11)O_(39)]^(8-) vacant Keggin moieties linked via Gd^(3+). Photocatalytic performance of K_(13)[Gd(GeW_(11)O_(39))_2]·34 H_2 O in photodegradation of X-3 B was also studied.When the reaction time is 180 min, the decoloring rate reaches 71.19%. With the decrease of pH, the decolorization rate increases gradually. | Haibin Liu Lin Bai Limei Ai Wenshuang Dai Danfeng Zhang Qingyin Wu Renchun Zhang | 2019 | Journal of Rare Earths2019，37，6： | 1 |

| 8 | Recent advances in the development of in vitro liver models for hepatotoxicity testing显示文摘Liver injury is a common cause of drug approval withdrawal during drug development,pre-clinical research,and clinical treatment.If not properly treated,patients with severe liver injury can suffer from acute liver failure or even death.Thus,utilization of the convenient in vitro hepatotoxicity assessment model for early detection of drug-induced hepatotoxicity is vital for drug development and safe personalized medication.Biomaterials(e.g.,hydrogels,nanofibers,decellularized liver matrix)and bioengineering technologies(e.g.,microarrays,micropatterns,3D printing,and microfluidics)have been applied for in vitro hepatotoxicity assessment models.This review summarizes the structure and functions of the liver as well as the components of in vitro hepatotoxicity assessment models.In addition,it highlights the latest advances in developing hepatotoxicity models with the ultimate goal of further clinical translation. | Siming Lu Jingwei Zhang Sha Lin Danfeng Zheng Yan Shen Jiale Qin Yangyang Li Shuqi Wang | 2021 | Bio-Design and Manufacturing2021，4，4： | 0 |
| 9 | The proximity between hydroxyl and single atom determines the catalytic reactivity of Rh1/CeO_(2) single-atom catalysts显示文摘The local structure of the metal single-atom site is closely related to the catalytic activity of metal single-atom catalysts(SACs).However,constructing SACs with homogeneous metal active sites is a challenge due to the surface heterogeneity of the conventional support.Herein,we prepared two Rh1/CeO_(2)SACs(0.5Rh1/r-CeO_(2)and 0.5Rh1/c-CeO_(2),respectively)using two shaped CeO_(2)(rod and cube)exposing different facets,i.e.,CeO_(2)(111)and CeO_(2)(100).In CO oxidation reaction,the T100 of 0.5Rh1/r-CeO_(2)SACs is 120°C,while the T100 of 0.5Rh1/c-CeO_(2)SACs is as high as 200°C.Via in-situ CO diffuse reflectance infrared Fourier transform spectroscopy(CO-DRIFTS),we found that the proximity between OH group and Rh single atom on the plane surface plays an important role in the catalytic activity of Rh1/CeO_(2)SAC system in CO oxidation.The Rh single atom trapped at the CeO_(2)(111)crystal surface forms the Rh1(OH)adjacent species,which is not found on the CeO_(2)(100)crystal surface at room temperature.Furthermore,during CO oxidation,the OH group far from Rh single atom on the 0.5Rh1/c-CeO_(2)disappears and forms Rh1(OH)adjacent species when the temperature is above 150°C.The formation of Rh1(OH)adjacentCO intermediate in the reaction is pivotal for the excellent catalytic activity,which explains the difference in the catalytic activity of Rh single atoms on two different CeO_(2)planes.The formed Rh1(OH)adjacent-O-Ce structure exhibits good stability in the reducing atmosphere,maintaining the Rh atomic dispersion after CO oxidation even when pre-reduced at high temperature of 500°C.Density functional theory(DFT)calculations validate the unique activity and reaction path of the intermediate Rh1(OH)adjacentCO species formed.This work demonstrates that the proximity between metal single atom and hydroxyl can determine the formation of active intermediates to affect the catalytic performances in catalysis. | Danfeng Wu Shuyun Zhou Congcong Du Juan Li Jianyu Huang Hong-xia Shen Abhaya K.Datye Shan Jiang Jeffrey T.Miller Sen Lin Haifeng Xiong | 2024 | Nano Research2024，17，1： | 0 |
| 10 | Filamentation initiated by Cas2 and its association with the acquisition process in cells显示文摘Cas1-and-Cas2-mediated new spacer acquisition is an essential process for bacterial adaptive immunity.The process is critical for the ecology of the oral microflora and oral health.Although molecular mechanisms for spacer acquisition are known,it has never been established if this process is associated with the morphological changes of bacteria.In this study,we demonstrated a novel Cas2-induced filamentation phenotype in E.coli that was regulated by co-expression of the Cas1 protein.A 30 amino acid motif at the carboxyl terminus of Cas2 is necessary for this function.By imaging analysis,we provided evidence to argue that Cas-induced filamentation is a step coupled with new spacer acquisition during which filaments are characterised by polyploidy with asymmetric cell division.This work may open new opportunities to investigate the adaptive immune response and microbial balance for oral health. | Lei Wang Xin Yu Mengjie Li Guiqin Sun Lin Zou Tiansheng Li Linlin Hou Yameng Guo Danfeng Shen Di Qu Xunjia Cheng Li Chen | 2019 | International Journal of Oral Science2019，11，4： | 0 |
| 11 | Evaluation of five DNA extraction methods for commercial vegetable oils显示文摘To ensure food safety, it's vital to accurately detect genetically modified(GM)ingredient adulteration in food products and effectively detect the adulteration of vegetable oils from GM organisms(GMO). Therefore, it's essential to establish efficient DNA isolation method from vegetable oil. Here, we evaluate 5 DNA isolation methods using 25 commercial vegetable oils produced from soybean, peanut, corn, sunflower, rapeseed as well as blended oils. Quality of isolated DNA was determined by Nanodrop 2000 spectrophotometry. Real-time PCR and universal gene tRNA-Leu was used to assess resolution of methods. Our results showed that only DNA samples isolated by modified emulsification method based on cetyl trimethylammonium bromide(CTAB) were able to amplify t RNA-Leu gene.Moreover, Ct values of species specific endogenous reference genes were greater than 36 in these samples. In summary, CTAB method showed the best resolution on GMO adulteration detection for commercial vegetable oils, especially in fully refined oils. | Yunjing Li Lin Shao Xiao Fang Danfeng Wan Yuhua Wu Jun Li Li Zhu Gang Wu | 2018 | Oil Crop Science2018，3，2： | 0 |
| 12 | Substrate,Hormone,Winnowing,and Stratification Influence the Seed Germination of Ilex asprella(Hook.et Arn.)Champ.ex Benth显示文摘Ilex asprella(Hook.et Arn.)Champ.ex Benth is one of the most important traditional Chinese medicines in southern China.The seeds of Ilex asprella usually have extremely low germination due to their dormancy characteristics,which severely impacts the efficiency of seedling raising and increases labor costs.In this study,to improve the seed germination of I.asprella,the effects of germination substrate,hormone,winnowing,and stratification treatments on the seed germination of I.asprella were investigated.The results of the germination matrix showed that the highest germination percentage of 45.2%was achieved under the 20℃/10℃day/night temperature and vermiculite germination medium conditions.The results of hormone treatments revealed that 100–400 mg/L of gibberellin(GA)and 50–100 mg/L of salicylic acid(SA)were found to be effective in releasing the dormancy of I.asprella seeds.Moreover,winnowing could effectively eliminate unsaturated seeds and impurities,thus improving the seed germination of I.asprella.Furthermore,warm temperature(15℃)stratification could expand the temperature range of I.asprella’s seed germination,which was beneficial for seed germination of I.asprella and for seed nursery at room temperature in production practice.The present study obtained a method to break dormancy and increase seed germination in I.asprella,thereby forming a groundwork for improving the efficiency of large-scale planting of I.asprella. | Yuquan Huang Fan Wei QingMa Yang Lin Jinpeng Huang Yanxia Zhu Danfeng Tang | 2023 | Phyton-International Journal of Experimental Botany2023，92，7： | 0 |
| 13 | Tongluo Huatan capsule(通络化痰胶囊) improves cognitive function by regulating the endocytosis of N-methyl-D-aspartic acid receptors mediated by clathrin in a rat model of vascular dementia显示文摘OBJECTIVE:To explore the neuroprotective mechanisms of Tongluo Huatan capsule(THC)in a rat model of vascular dementia(VD).METHODS:A rat model of VD was established by repeated clamping of bilateral common carotid arteries with the intraperitoneal injection of sodium nitroprusside solution.VD rats were administered THC,memantine hydrochloride,or distilled water daily for 14 d after operation.Learning and memory abilities were assessed using the step-down passive avoidance test,novel object recognition(NOR)test,and Morris water maze(MWM)test.Pathological changes in the hippocampus were observed through hematoxylin and eosin and Nissl staining.The expression levels of clathrin,RAB5 B,andN-methyl-D-aspartic acid receptor 1(NMDAR1)were measured by immunohistochemistry staining,real-time quantitative polymerase chain reaction and Western blot.RESULTS:Rats in VD group showed impaired learning and memory abilities(step-down passive avoidance,NOR,and MWM)and abnormalities in neuronal morphology(light microscopy)in the hippocampus.The m RNA or protein expression levels of clathrin and RAB5 B were decreased,and NMDAR1 was increased in hippocampal tissues(P<0.05).Administration of THC promoted the learning and memory abilities and the morphological structure of hippocampal neurons in VD rats.Besides,THC enhanced m RNA or protein expression levels of clathrin and RAB5 B,and decreased NMDAR1(P<0.05).CONCLUSION:THC may improve cognitive functions by regulating the endocytosis of NMDA receptors mediated by clathrin. | GAO Qiang TIAN Danfeng ZHANG Dandan GUO Yang-yang LIN Jingfeng LIU Ganlu CHANG Ze WANG Yuc-hun HAN Zhenyun | 2021 | Journal of Traditional Chinese Medicine2021，41，5： | 0 |
| 14 | The dusty and extremely red progenitor of the typeⅡsupernova 2023ixf in Messier 101显示文摘Stars with initial masses in the range of 8-25 solar masses are thought to end their lives as hydrogen-rich supernovae(SNeⅡ).Based on the pre-explosion images of Hubble space telescope(HST)and Spitzer space telescope,we place tight constraints on the progenitor candidate of type IIP SN 2023ixf in Messier 101.Fitting of the spectral energy distribution(SED)of its progenitor with dusty stellar spectral models results in an estimation of the effective temperature as 3091+422-258K.The luminosity is estimated as lg(L/L⊙)~4.83,consistent with a red supergiant(RSG)star with an initial mass of 12-1+2M⊙.The derived mass loss rate(6×10^(-6)-9×10^(-6)M⊙yr^(-1))is much lower than that inferred from the flash spectroscopy of the SN,suggesting that the progenitor experienced a sudden increase in mass loss when approaching the final explosion.In the infrared bands,significant deviation from the range of regular RSGs in the color-magnitude diagram and period-luminosity space of the progenitor star indicates enhanced mass loss and dust formation.Combined with new evidence of polarization at the early phases of SN 2023ixf,such a violent mass loss is likely a result of binary interaction. | Danfeng Xiang Jun Mo Lingzhi Wang Xiaofeng Wang Jujia Zhang Han Lin Lifan Wang | 2024 | Science China(Physics,Mechanics & Astronomy)2024，67，1： | 0 |
