| 1 | Denitrifying phosphorus removal in a step-feed CAST with alternating anoxic-oxic operational strategy显示文摘A bench-scale cyclic activated sludge technology(CAST) was operated to study the biological phosphorus removal performance and a series of batch tests was carried out to demonstrate the accumulation of denitrifying polyphosphate-accumulating organisms(DNPAOs) in CAST system.Under all operating conditions,step-feed CAST with enough carbon sources in influent had the highest nitrogen and phosphorus removal effciency as well as good sludge settling performance.The average removal rate of COD,NH4+-N,PO43--P and total nitrogen(TN) was 88.2%,98.7%,97.5% and 92.1%,respectively.The average sludge volume index(SVI) was 133 mL/g.The optimum anaerobic/aerobic/anoxic(AOA) conditions for the cultivation of DNPAOs could be achieved by alternating anoxic/oxic operational strategy,thus a significant denitrifying phosphorus removal occurred in step-feed CAST.The denitrification of NOx--N completed quickly due to step-feed operation and enough carbon sources,which could enhance phosphorus release and further phosphorus uptake capability of the system.Batch tests also proved that polyphosphate-accumulating organisms(PAOs) in the step-feed process had strong denitrifying phosphorus removal capacity.Both nitrate and nitrite could be used as electron acceptors in denitrifying phosphorus removal.Low COD supply with step-feed operation strategy would favor DNPAOs accumulation. | MA Juan PENG Yongzhen WANG Shuying WANG Li LIU Yangt MA Ningpin | 2009 | Journal of Environmental Sciences2009，21，9： | 27 |
| 2 | Unscented extended Kalman filter for target tracking显示文摘A new method of unscented extended Kalman filter (UEKF) for nonlinear system is presented. This new method is a combination of the unscented transformation and the extended Kalman filter (EKF). The extended Kalman filter is similar to that in a conventional EKF. However, in every running step of the EKF the unscented transformation is running, the deterministic sample is caught by unscented transformation, then posterior mean of nonlinearity is caught by propagating, but the posterior covariance of nonlinearity is caught by linearizing. The accuracy of new method is a little better than that of the unscented Kalman filter (UKF), however, the computational time of the UEKF is much less than that of the UKF. | Changyun Liu Penglang Shui Song Li | 2011 | Journal of Systems Engineering and Electronics2011，22，2： | 21 |
| 3 | Chimeric antigen receptor-engineered T-cell therapy for liver cancer显示文摘Background: Chimeric antigen receptor-engineered T-cell(CAR-T) therapy is a newly developed immunotherapy used in the treatment of cancers. Because CAR-T therapy has shown great success in treating CD19-positive hematological malignancies, its application has been explored in the treatment of solid tumors, such as liver cancer. In this review, we discuss the immune characteristics of liver cancer, the obstacles encountered during the application of CAR-T therapy, and preclinical and clinical progress in the use of CAR-T therapy in patients with liver cancer.Data sources: The data on CAR-T therapy related to liver cancers were collected by searching Pub Med and the Web of Science databases prior to December 2017 with the keywords 'chimeric antigen receptor','CAR-T', 'liver cancer', 'hepatocellular carcinoma', and 'solid tumor'. Additional articles were identified by manual search of references found in the primary articles. The data for clinical trials were collected by searching Clinical Trials.gov.Results: The liver has a tolerogenic nature in the intrahepatic milieu and its tumor microenvironment significantly affects tumor progression. The obstacles that reduce the efficacy of CAR-T therapy in solid tumors include a lack of specific tumor antigens, limited trafficking and penetration of CAR-T cells to tumor sites, and an immunosuppressive tumor microenvironment. To overcome these obstacles, several strategies have emerged. In addition, several strategies have been developed to manage the side effects of CAR-T, including enhancing the selectivity of CARs and controlling CAR-T activity. To date, no clinical trials of CAR-T therapy against HCC have been completed. However, preclinical studies in vitro and in vivo have shown potent antitumor efficacy. Glypican-3, mucin-1, epithelial cell adhesion molecule, carcinoembryonic antigen, and other targets are currently being studied.Conclusions: The application of CAR-T therapy for liver cancer is just beginning to be explored and more research is needed. However, we are optimistic that CAR-T therapy will offer a new approach for the treatment of liver cancers in the future. | Yang Chen Chang-Yong E Zhi-Wen Gong Shui Liu Zhen-Xiao Wang Yong-Sheng Yang Xue-Wen Zhang | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，4： | 16 |
| 4 | The Interactions among DWARF10,Auxin and Cytokinin Underlie Lateral Bud Outgrowth in Rice显示文摘Previous studies have shown that DWARF10(D10) is a rice ortholog of MAX4/RMS1/DAD1,encoding a carotenoid cleavage dioxygenase and functioning in strigolactones/strigolactone-derivatives(SL) biosynthesis.Here we use D10-RNA interference(RNAi) transgenic plants similar to d10 mutant in phenotypes to investigate the interactions among D10,auxin and cytokinin in regulating rice shoot branching.Auxin levels in node 1 of both decapitated D10-RNAi and wild type plants decreased significantly,showing that decapitation does reduce endogenous auxin concentration,but decapitation has no clear effects on auxin levels in node 2 of the same plants.This implies that node 1 may be the location where a possible interaction between auxin and D10 gene would be detected.D10 expression in node 1 is inhibited by decapitation,and this inhibition can be restored by exogenous auxin application,indicating that D10 may play an important role in auxin regulation of SL.The decreased expression of most OsPINs in shoot nodes of D10-RNAi plants may cause a reduced auxin transport capacity.Furthermore,effects of auxin treatment of decapitated plants on the expression of cytokinin biosynthetic genes suggest that D10 promotes cytokinin biosynthesis by reducing auxin levels.Besides,in D10-RNAi plants,decreased storage cytokinin levels in the shoot node may partly account for the increased active cytokinin contents,resulting in more tillering phenotypes. | Shuying Zhang Gang Li Jun Fang Weiqi Chen Haipai Jiang Junhuang Zou Xue Liu Xianfeng Zhao Xiaobing Li Chengcai Chu Qi Xie Xiangning Jiang Lihuang Zhu | 2010 | Journal of Integrative Plant Biology2010，52，7： | 14 |
| 5 | Hypoxia-induced factor-1 alpha upregulates vascular endothelial growth factor C to promote lymphangiogenesis and angiogenesis in breast cancer patients显示文摘Hypoxia-induced factor-1 alpha(HIF-1α)affects many effector molecules and regulates tumor lymphangiogenesis and angiogenesis during hypoxia.The aim of this study was to investigate the role of HIF-1αin the regulation of vascular endothelial growth factor C(VEGF-C)expression and its effect on lymphangiogenesis and angiogenesis in breast cancer.Lymphatic vessel density(LVD),microvessel density(MVD)and the expressions of HIF-1αand VEGF-C proteins were evaluated by immunohistochemistry in 75 breast cancer samples.There was a significant correlation between HIF-1αand VEGF-C(P=0.014,r=0.273,Spearman's coefficient of correlation).HIF-1αand VEGF-C overexpression was significantly correlated with higher LVD(P=0.003 and P=0.017,respectively),regional lymph nodal involvement(P=0.002 and P=0.004,respectively)and advanced tumor,node,metastasis(TNM)classification(P=0.001 and P=0.01,respectively).Higher MVD was observed in the group expressing higher levels of HIF-1αand VEGF-C(P=0.033 and P=0.037,respectively).Univariate analysis showed shorter survival time in patients expressing higher levels of HIF-1αand VEGF-C.HIF-1αwas also found to be an independent prognostic factor of overall survival in multivariate analysis.The results suggest that HIF-1αmay affect VEGF-C expression,thus acting as a crucial regulator of lymphangiogenesis and angiogenesis in breast cancer.This study highlights promising potential of HIF-1αas a therapeutic target against tumor lymph node metastasis. | Xiaojian Ni Yingchun Zhao Jingjing Ma Tiansong Xia Xiaoan Liu Qiang Ding Xiaoming Zha Shui Wang | 2013 | The Journal of Biomedical Research2013，27，6： | 10 |

| 9 | Boosting electrocatalytic water splitting via metal-metalloid combined modulation in quaternary Ni-Fe-P-B amorphous compound显示文摘Design and synthesis of highly efficient and cost-effective bifunctional catalysts for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)remain a big challenge.Herein,a quaternary amorphous nanocompound Ni-Fe-P-B has been synthesized by a facile,scalable co-reduction method.The Ni-Fe-P-B exhibits high electrocatalytic activity and outstanding durability for both HER and OER,delivering a current density of 10 mA·cm^-2 at overpotentials of 220 and 269 mV,respectively.When loaded on carbon fiber paper(CFP)as a bifunctional catalyst,the Ni-Fe-P-B@CFP electrode requires a low cell voltage of 1.58 V to obtain 10 mA·cm^-2 for overall water splitting with negligible recession over 60 h.The excellent catalytic performances of Ni-Fe-P-B mainly benefit from the metal-metalloid combined composition modulation and the unique amorphous structure.This work provides new insights into the design of robust bifunctional catalysts for water splitting,and may promote the development of multicomponent amorphous catalysts. | Wukui Tang Xiaofang Liu Ya Li Yanhui Pu Yao Lu Zhiming Song Qiang Wang Ronghai Yu Jianglan Shui | 2020 | Nano Research2020，13，2： | 8 |

| 11 | Modified unscented Kalman filter using modified filter gain and variance scale factor for highly maneuvering target tracking显示文摘To improve the low tracking precision caused by lagged filter gain or imprecise state noise when the target highly maneuvers, a modified unscented Kalman filter algorithm based on the improved filter gain and adaptive scale factor of state noise is presented. In every filter process, the estimated scale factor is used to update the state noise covariance Qk, and the improved filter gain is obtained in the filter process of unscented Kalman filter(UKF)via predicted variance Pk|k-1, which is similar to the standard Kalman filter. Simulation results show that the proposed algorithm provides better accuracy and ability to adapt to the highly maneuvering target compared with the standard UKF. | Changyun Liu Penglang Shui Gang Wei Song Li | 2014 | Journal of Systems Engineering and Electronics2014，25，3： | 8 |

| 13 | Environmentally Tough and Stretchable MXene Organohydrogel with Exceptionally Enhanced Electromagnetic Interference Shielding Performances显示文摘Conductive hydrogels have potential applications in shielding electromagnetic(EM)radiation interference in deformable and wearable electronic devices,but usually suffer from poor environmental stability and stretching-induced shielding performance degradation.Although organohydrogels can improve the environmental stability of materials,their development is at the expense of reducing electrical conductivity and thus weakening EM interference shielding ability.Here,a MXene organohydrogel is prepared which is composed of MXene network for electron conduction,binary solvent channels for ion conduction,and abundant solvent-polymer-MXene interfaces for EM wave scattering.This organohydrogel possesses excellent anti-drying ability,low-temperature tolerance,stretchability,shape adaptability,adhesion and rapid self-healing ability.Two effective strategies have been proposed to solve the problems of current organohydrogel shielding materials.By reasonably controlling the MXene content and the glycerol-water ratio in the gel,MXene organohydrogel can exhibit exceptionally enhanced EM interference shielding performances compared to MXene hydrogel due to the increased physical cross-linking density of the gel.Moreover,MXene organohydrogel shows attractive stretching-enhanced interference effectiveness,caused by the connection and parallel arrangement of MXene nanosheets.This well-designed MXene organohydrogel has potential applications in shielding EM interference in deformable and wearable electronic devices. | Yuanhang Yu Peng Yi Wenbin Xu Xin Sun Gao Deng Xiaofang Liu Jianglan Shui Ronghai Yu | 2022 | Nano-Micro Letters2022，14，5： | 6 |
| 14 | STAT3 mediates resistance of CD44^+CD24^(-/low) breast cancer stem cells to tamoxifen in vitro显示文摘We sought to determine whether STAT3 mediated tamoxifen resistance of breast cancer stem cells in vitro.The capacities for mammosphere formation and STAT3 expression of CD44+CD24-/low MCF-7 and MCF-7 were observed.The CD44+CD24-/low subpopulation ratio and its sensitivity to adriamycin were analyzed in MCF-7 and TAM resistant(TAM-R) cells.Cell cycle,apoptosis,STAT3 and phospho-STAT3 changes were observed af-ter treatment with tamoxifen.Small interference RNA-mediated knockdown of STAT3 in TAM-R cells was also performed.CD44+CD24-/low MCF-7 showed higher capacities for mammosphere formation and STAT3 expression than total MCF-7.The CD44+CD24-/low subpopulation was also upregulated in TAM-R cells with less sensitivity to adriamycin than MCF-7.Cell cycle changes,anti-apoptotic effects and STAT3 changes were also found.Mean-while,the knock-down of STAT3 in TAM-R resulted in an increase in sensitivity to tamoxifen.It is concluded that STAT3 plays an essential role in breast cancer stem cells,which correlated with tamoxifen resistance. | Xiaoyan Wang Guozhu Wang Yi Zhao Xiaoan Liu Qiang Ding Jingping Shi Yin Ding Shui Wang | 2012 | The Journal of Biomedical Research2012，26，5： | 6 |
| 15 | Plastome-wide comparison reveals new SNV resources for the authentication of Dendrobium huoshanense and its corresponding medicinal slice(Huoshan Fengdou)显示文摘Dendrobium species and their corresponding medicinal slices have been extensively used as traditional Chinese medicine(TCM) in many Asian countries. However, it is extremely difficult to identify Dendrobium species based on their morphological and chemical features. In this study, the plastomes of D. huoshanense were used as a model system to investigate the hypothesis that plastomic mutational hotspot regions could provide a useful single nucleotide variants(SNVs) resource for authentication studies. We surveyed the plastomes of 17 Dendrobium species, including the newly sequenced plastome of D. huoshanense. A total of 19 SNVs that could be used for the authentication of D. huoshanense were detected. On the basis of this comprehensive comparison, we identified the four most informative hotspot regions in the Dendrobium plastome that encompass ccsA to ndhF, matK to 3′trnG, rpoB to psbD, and trnT to rbcL. Furthermore, to established a simple and accurate method for the authentication of D. huoshanense and its medicinal slices, a total of 127 samples from 20 Dendrobium species including their corresponding medicinal slices(Fengdous) were used in this study. Our results suggest that D. huoshanense and its medicinal slices can be rapidly and unequivocally identified using this method that combines real-time PCR with the amplification refractory mutation system(ARMS). | Zhitao Niu Jiajia Pan Qingyun Xue Shuying Zhu Wei Liu Xiaoyu Ding | 2018 | Acta Pharmaceutica Sinica B2018，8，3： | 6 |
| 16 | Auranofin mitigates systemic iron overload and induces ferroptosis via distinct mechanisms显示文摘Iron homeostasis is essential for health;moreover,hepcidin-deficiency results in iron overload in both hereditary hemochromatosis and iron-loading anemia.Here,we identified iron modulators by functionally screening hepcidin agonists using a library of 640 FDA-approved drugs in human hepatic Huh7 cells.We validated the results in C57BL/6J mice and a mouse model of hemochromatosis(Hfe^(−/−)mice).Our screen revealed that the anti-rheumatoid arthritis drug auranofin(AUR)potently upregulates hepcidin expression.Interestingly,we found that canonical signaling pathways that regulate iron,including the Bmp/Smad and IL-6/Jak2/Stat3 pathways,play indispensable roles in mediating AUR’s effects.In addition,AUR induces IL-6 via the NF-κB pathway.In C57BL/6J mice,acute treatment with 5 mg/kg AUR activated hepatic IL-6/hepcidin signaling and decreased serum iron and transferrin saturation.Whereas chronically treating male Hfe^(−/−)mice with 5 mg/kg AUR activated hepatic IL-6/hepcidin signaling,decreasing systemic iron overload,but less effective in females.Further analyses revealed that estrogen reduced the ability of AUR to induce IL-6/hepcidin signaling in Huh7 cells,providing a mechanistic explanation for ineffectiveness of AUR in female Hfe^(−/−)mice.Notably,high-dose AUR(25 mg/kg)induces ferroptosis and causes lipid peroxidation through inhibition of thioredoxin reductase(TXNRD)activity.We demonstrate the ferroptosis inhibitor ferrostatin significantly protects liver toxicity induced by highdose AUR without comprising its beneficial effect on iron metabolism.In conclusion,our findings provide compelling evidence that TXNRD is a key regulator of ferroptosis,and AUR is a novel activator of hepcidin and ferroptosis via distinct mechanisms,suggesting a promising approach for treating hemochromatosis and hepcidin-deficiency related disorders. | Lei Yang Hao Wang Xiang Yang Qian Wu Peng An Xi Jin Weiwei Liu Xin Huang Yuzhu Li Shiyu Yan Shuying Shen Tingbo Liang Junxia Min Fudi Wang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 5 |
| 17 | Treatment patterns for adjuvant docetaxel-based chemotherapy in early-stage breast cancer in China:A pooled retrospective analysis of four observational studies显示文摘Objective:Adjuvant docetaxel-based chemotherapy is frequently used for operable early breast cancer(EBC).This study investigated patterns of use of docetaxel(T)in real-life clinical practice in China.Methods:This was a retrospective pooled analysis of the Asia-Pacific Breast Initiatives(APBI)Ⅰ(2006–2008)and Ⅱ(2009–2011)registries,and two Chinese observational studies;BC STATE(2011–2014)and BC Local Registry(2007–2010).Female Chinese adults(≥18 years)with operable breast cancer treated with docetaxel-based adjuvant chemotherapy were included in the analysis.Patients with metastatic disease were excluded.The primary endpoint was assessment of treatment patterns and patient profiles.A logistic regression analysis was conducted to identify factors associated with choice of adjuvant chemotherapy regimen.Results:Data from 3,020 patients were included.The most frequently used adjuvant regimen was docetaxel/anthracycline combination[n=1,421(47.1%);of whom 52.0%received T/epirubicin(E)/cyclophosphamide(C)],followed by docetaxel/other[n=705(23.3%);of whom 72.8%received TC],docetaxel/anthracycline sequential[n=447(14.8%);of whom 40.9%and 39.6%received 5-Fu/EC-T and EC-T,respectively],and'other'[n=447(14.8%);of whom 91.5%received T].A significant association was found between adjuvant therapy with docetaxel/anthracycline combination and patient weight,menopausal status and estrogen receptor status.Conclusions:Real-world data revealed that docetaxel/anthracycline combination is the most commonly used category of docetaxel-based adjuvant therapy for patients with operable breast cancer in China;of which TEC is the most frequently used regimen. | Binghe Xu Zhimin Shao Shui Wang Zefei Jiang Xichun Hu Xiaohua Zhang Xiru Li Jinping Liu Mengquan Li Shu Wang | 2018 | Chinese Journal of Cancer Research2018，30，3： | 5 |

| 19 | Microwave ablation of primary breast cancer inhibits metastatic progression in model mice via activation of natural killer cells显示文摘Surgery is essential for controlling the symptoms and complications of stage IV breast cancer.However,locoregional treatment of primary tumors often results in distant progression,including lung metastasis,the most common type of visceral metastasis.As a minimally invasive thermal therapy,microwave ablation(MWA)has been attempted in the treatment of breast cancer,but the innate immune response after MWA has not yet been reported.Using two murine models of stage IV breast cancer,we found that MWA of primary breast cancer inhibited the progression of lung metastasis and improved survival.NK cells were activated after MWA of the primary tumor and exhibited enhanced cytotoxic functions,and the cytotoxic pathways of NK cells were activated.Depletion experiments showed that NK cells but not CD4+or CD8+T cells played a pivotal role in prolonging survival.Then,we found that compared with surgery or control treatment,MWA of the primary tumor induced completely different NK-cell-related cytokine profiles.Macrophages were activated after MWA of the primary tumor and produced IL-15 that activated NK cells to inhibit the progression of metastasis.In addition,MWA of human breast cancer stimulated an autologous NK-cell response.These results demonstrate that MWA of the primary tumor in metastatic breast cancer inhibits metastatic progression via the macrophage/IL-15/NK-cell axis.MWA of the primary tumor may be a promising treatment strategy for de novo stage IV breast cancer,although further substantiation is essential for clinical testing. | Muxin Yu Hong Pan Nan Che Li Li Cong Wang Yue Wang Ge Ma Mengjia Qian Jiawei Liu Mingjie Zheng Hui Xie Lijun Ling Yi Zhao Xiaoxiang Guan Qiang Ding Wenbin Zhou Shui Wang | 2021 | Cellular & Molecular Immunology2021，18，9： | 5 |
| 20 | Differentiation of smooth muscle progenitor cells in peripheral blood and its application in tissue engineered blood vessels显示文摘Background: A major shortcoming in tissue engineered blood vessels (TEBVs) is the lack of healthy and easily attainable smooth muscle cells (SMCs). Smooth muscle progenitor cells (SPCs), especially from peripheral blood, may offer an alternative cell source for tissue engineering involving a less invasive harvesting technique. Methods: SPCs were isolated from 5-ml fresh rat peripheral blood by density-gradient centrifugation and cultured for 3 weeks in endothelial growth medium-2-MV (EGM-2-MV) medium containing platelet-derived growth factor-BB (PDGF BB). Before seeded on the synthesized scaffold, SPC-derived smooth muscle outgrowth cell (SOC) phenotypes were assessed by immuno-fluorescent staining, Western blot analysis, and reverse transcription polymerase chain reaction (RT-PCR). The cells were seeded onto the silk fibroin-modified poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (SF-PHBHHx) scaffolds by 6×104 cells/cm2 and cultured under the static con- dition for 3 weeks. The growth and proliferation of the seeded cells on the scaffold were analyzed by 3-(4,5-dimethylthiazol-2-yl)- diphenyltetrazolium bromide (MTT) assay, scanning electron microscope (SEM), and 4,6-diamidino-2-phenylindole (DAPI) staining. Results: SOCs displayed specific 'hill and valley' morphology, expressed the specific markers of the SMC lineage: smooth muscle (SM) α-actin, calponin and smooth muscle myosin heavy chain (SM MHC) at protein and messenger ribonucleic acid (mRNA) levels. RT-PCR results demonstrate that SOCs also expressed smooth muscle protein 22α (SM22α), a contractile protein, and extracellular matrix components elastin and matrix Gla protein (MGP), as well as vascular endothelial growth factor (VEGF). After seeded on the SF-PHBHHx scaffold, the cells showed excellent metabolic activity and proliferation. Conclusion: SPCs isolated from peripheral blood can be differentiated into the SMCs in vitro and have an impressive growth potential in the biodegradable synthesized scaffold. Thus, SPCs may be a promising cell source for constructing TEBVs. | Shang-zhe XIE Ning-tao FANG Shui LIU Ping ZHOU Yi ZHANG Song-mei WANG Hong-yang GAO Luan-feng PAN | 2008 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008，9，12： | 5 |
