| 1 | Current status and future perspectives of immunotherapy in bladder cancer treatment显示文摘The treatment strategy of bladder cancer has evolved not only through the traditional modalities of surgery and chemotherapy but also by immunotherapy over the past several decades.Immunotherapies such as intravesical Bacillus Calmette-Guérin(BCG)vaccines and immune checkpoint blockades(ICBs)are sometimes used for treating patients with bladder cancer,especially those who develop resistance to conventional first-line treatments such as surgery and chemotherapy.Unfortunately,it is a limited number of individuals that see clinical benefits from this approach,and complicating matters more is that many of these patients suffer severe immune-related adverse events(ir AEs).If current momentum continues to result in improved response rates and managed ir AEs,immunotherapy could be poised to revolutionize the landscape of urothelial carcinoma therapeutics. | Zhangsong wu Jinjian Liu Ruixiang Dai Song Wu | 2021 | Science China(Life Sciences)2021，64，4： | 6 |
| 2 | Community structure and controlled factor of attached green algae on the Porphyra yezoensis aquaculture rafts in the Subei Shoal, China显示文摘This study analyzes the community structure, the quantity changes of the algae and the effect of important environmental factors and estimates the total biomass of the attached green algae in the survey areas. The study uses data from surveys of the attached green algae on the Porphyra yezoensis aquaculture rafts and data regarding the environmental factors from October 2010 to April 2011 in the Subei Shoal. The attached green algae on the rafts included Ulva prolifera, Capsosiphon groenlandicus, U. linza, U. intestinalis, U. clathrata, and U. compressa.The biomass changes of the attached green algae exhibited an inverted parabola: the biomass was the highest(14 898 t) in April, and was the second highest(2 034 t) in November; it was lowest in February(only 729 t) and increased sharply from March to April. The species diversity differed significantly among the seasons. In September and October, when the P. yezoensis aquaculture rafts were initially set up, the attached green algae had a high biodiversity, while from December to the next February, a variety of green algae species coexisted on the rafts, although the biomass was low, and from March to April, as the biomass increased sharply, the species diversity dropped to the minimum. During this time, C. groenlandicus was apparently dominant with the maximum biomass proportion up to 80%, while the U. prolifera proportion increased exponentially to 20% to 40%.The water temperature had a direct regulating effect on the biomass and the species succession of the attached green algae. The estimation of the community dynamics and the biomass of the green algae provided the evidence needed to track the origin of the large-scale green tide in the southern Yellow Sea. | LI Yan XIAO Jie DING Lanping WANG Zongling SONG Wei FANG Song FAN Shiliang LI Ruixiang ZHANG Xuelei | 2015 | Acta Oceanologica Sinica2015，34，8： | 6 |
| 3 | Flexible ITO-free organic solar cells over 10% by employing drop-coated conductive PEDOT:PSS transparent anodes显示文摘Highly conductive poly(3,4-ethylenedioxythiophene):poly(styrene-sulfonic acid)(PEDOT:PSS) has been explored to fabricate flexible and stretchable conductors. Generally, PEDOT:PSS transparent anodes are prepared by spin-coating method. In this article, we adopt a method by dropping PEDOT:PSS aqueous solution on the PET plastic substrate to fabricate flexible electrodes. Compared with spin coating, drop-coating is simple and cost-effective with large-area fabrications. Through this method, we fabricated highly transparent conductive electrodes and systematically studied their electrical, optical, morphological and mechanical properties. With dimethyl sulfoxide/methanesulfonic acid(DMSO/MSA) treated PEDOT:PSS electrode,bendable devices based on non-fullerene system displayed an open-circuit voltage of 0.925 V, a fill factor of 70.74%, and a high power conversion efficiency(PCE) of 10.23% under 100 mW cm^(-2) illumination, which retained over 80% of the initial PCE value after 1000 bending cycles. Based on the findings, drop-coated PEDOT:PSS electrodes exhibited high suitability for the development of large-area and high-efficiency printed solar cell modules in the future. | Huiqin Cui Wei Song Billy Fanady Ruixiang Peng Jianfeng Zhang Jiaming Huang Ziyi Ge | 2019 | Science China Chemistry2019，62，4： | 3 |
| 4 | High efficiency ternary organic solar cells enabled by compatible dual-donor strategy with planar conjugated structures显示文摘Ternary organic solar cells(OSCs) have received extensive attention for improving the power conversion efficiency(PCE) of organic photovoltaics(OPVs). In this work, a novel donor material(ECTBD) consisting of benzodithiophene(BDT) central electron donor unit was developed and synthesized. The small molecular donor has the same central unit as PM6. The addition of ECTBD into PM6:Y6 system could improve the morphology of active blend layer. In addition, ECTBD showed good morphologically compatibility when blending with PM6:Y6 host, resulting in the improvement of fill factor and current density. As a result, the ternary devices based on PM6:ECTBD:Y6 ternary system achieved a highest PCE of 16.51% with fill factor of 76.24%, which was much higher than that of the binary devices(15.7%). Overall, this work provided an effective strategy to fabricate highly efficient ternary organic solar cells through design of the novel small molecular donor as the third component. | Sanhui Chen Tingting Yan Billy Fanady Wei Song Jinfeng Ge Qiang Wei Ruixiang Peng Guohui Chen Yingping Zou Ziyi Ge | 2020 | Science China Chemistry2020，63，7： | 2 |
| 5 | Measurement and influencing factors of urban traffic ecological resilience in developing countries: A case study of 31 Chinese cities显示文摘An urban traffic ecosystem is a spatial structure composed of air,population,vehicles,roads,green spaces,and regions.Traffic ecological resilience is a critical issue in high-quality urban development.From the perspective of system optimization,it is important to study the level of urban traffic ecological resilience and analyze its influencing factors.In this study,we evaluated traffic ecological resilience,characterized its spatio-temporal differentiation,and explored its influencing factors by constructing a system of urban traffic ecological resilience and by analyzing the environmental protection and urban construction data in 31 Chinese cities during 2011-2018.By conducting Kernel density analysis,standard deviation ellipse,comprehensive weight determination,panel data regression analysis,andχ2test,we found that traffic ecological resilience was low on the whole and exhibited the temporal trend of“decreasing first and then increasing”and the spatial characteristic of“high in the east,second in the middle,and low in the west”.The cities with high traffic ecological resilience density values were located in Southeast China and tended to move from northwest to southeast.Governance capability,market activity,technological innovation capability,opening degree,and financial resources had significant effects on urban traffic ecological resilience.Finally,we gave some suggestions for improving the urban traffic ecological resilience in Chinese cities as well as other developing countries in the world. | HU Xiwu SU Yunqing REN Kefeng SONG Fang XUE Ruixiang | 2021 | Regional Sustainability2021，2，3： | 1 |
| 6 | Entropy-driven phase regulation of high-entropy transition metal oxide and its enhanced high-temperature microwave absorption by in-situ dual phases显示文摘High-temperature microwave absorbers are significant for military equipment which experiences severe aerodynamic heat.In this work,high-entropy oxide(HEO)(FexCoNiCrMn)mOn with excellent high-temperature microwave absorption is studied.Driven by the effect of entropy,the composition of the oxide can be transformed from spinel-type phase(FexCoNiCrMn)_(3)O_(4) to corundum-type phase(FexCoNiCrMn)2O3 with the increasing content of iron.Only spinel-type or corundum-type structure composes the oxide when x≤3 or x≥5.But in-situ dual phases can coexist when x equals 4 during phase transition.Interestingly,obliged to abundant heterogeneous interfaces and crystal defects in the dual-phase HEO,magnetic property,dielectric polarization,and microwave loss ability are all well enhanced.The Smith chart analysis demonstrates the impedance matching condition is well improved due to the enhanced loss ability.These findings pave a new way for the adjustment of electromagnetic properties of HEO by entropy-driven phase regulation.Meanwhile,the dual-phase absorber can achieve better than 90%absorption in 9.6-12.4 GHz at 800℃ with a thickness of 2.6 mm,a low thermal diffusivity of 0.0038 cm^(2)/s at 900℃,and excellent high-temperature stability,which indicates it’s promising as a high-temperature microwave absorber. | Guohao Dai Ruixiang Deng Xiao You Tao Zhang Yun Yu Lixin Song | 2022 | Journal of Materials Science & Technology2022，，21： | 1 |
| 7 | The natural course of bacillus Calmette-Guerin induced bladder lesions:A long-term follow-up study and systematic review显示文摘Objective:Bacillus Calmette-Gue´rin(BCG)instillation is the standard adjuvant treatment for intermediate-and high-risk non-muscle-invasive bladder cancer after transurethral resection.Nevertheless,its toxicity often causes bladder complications.On follow-up cystoscopy,post-BCG bladder lesions can be pathologically benign,urothelial carcinoma recurrence,or other types of bladder malignancy.Only a small number of case reports have been published on post-BCG bladder lesions.Their clinical features,natural course,and management remain unknown.Methods:We retrospectively studied cystoscopic videos and medical records of BCG-treated bladder cancer patients at our center.During a long-term follow-up,we took biopsies on tumor-like lesions and described their changes.In addition,we summarized previous studies on post-BCG bladder lesions by systematic literature searching and review.Results:We described a series of three cases with post-BCG bladder lesions mimicking tumor recurrence from a total of 38 cases with follow-up data for more than 5 years.Those lesions could last,grow,or disappear spontaneously,and remain pathological benign for years.In systematic review,we identified and analyzed a total of 15 cases with post-BCG bladder lesions with detailed clinical information.Eleven of the 15 were benign and have a good prognosis with nephrogenic adenoma being the most common pathological type.Conclusion:Based on previous studies and our experience,benign lesions after BCG instillation cannot distinguish with cancer recurrence by cystoscopy alone,even under narrow band imaging mode.Nonetheless,given most of them have a good prognosis,random biopsy or transurethral resection might be spared in the patients with long-term negative biopsy and urine cytology. | Chong Ma Shuxiong Zeng Lihe Dai Huan Han Ruixiang Song Jinshan Xu Xing Ai Chuanliang Xu | 2023 | Asian Journal of Urology2023，10，3： | 0 |
| 8 | Synthesis of sillenite-type Bi3sFe2O57and elemental bismuth with visible-light photocatalytic activity for water treatment显示文摘With Fe(NO3)3 9H2O and Bi(NO3)3 5H2Oas raw materials, different sillenite-type compounds and elemental bismuth were prepared by a facile one-pot solvothermal method using H2O, C2H5OH, (CH2OH)2 and C3H8O3 as solvents, respec-tively. The structure, morphology, elemental compositions and properties of samples were examined by XRD, SEM, TEM, ICP, XPS, N2 adsorption and desorption, UV-vis DRS and PL. The photocatalytic activities of different samples were evaluated by the photodegradation of RhB under visible-light irradiation (λ>400 nm), and results show that Bi36Fe2O57 prepared using C2H5OH as the solvent owns the optimum performance. In order to explore the reaction mechanism, an additional experiment was designed to investigate the main active species during the photodegradation process via dissolving different trapping agents in the reaction solution before light irradiation. The results show that superoxide radical anions play a major role in this system since the RhB degradation was significantly suppressed after the addition of benzoquinone. | Chuan DENG Xianxian WEI Ruixiang LIU Yajie DU Lei PAN Xiang ZHONG Jianhua SONG | 2018 | Frontiers of Materials Science2018，12，4： | 0 |
| 9 | Efficient ternary organic solar cells based on a twin spiro-type non-fullerene acceptor显示文摘A novel small-molecule(SM) acceptor DTF-IC is designed and synthesized in this work. The power conversion efficiency(PCE) of ternary OSCs increased up to 12.14% from 10.90% by incorporating 10 wt% of DTF-IC as second acceptors into the binary OSCs consisting of PBDB-T as donor and IT-M as acceptor. This was mainly due to the large increase in short-circuit current(Jsc) from 16.18 to 17.95 mA/cm^2, without any drop in the open-circuit voltage(Voc) and fill factor(FF). The addition of DTF-IC enabled the donor and acceptor to form a distinct complementary absorption profile in the visible-light region, which boosted the photon harvesting in the range of 730–800 nm and consequently increased the Jscof the ternary system by 11%. Moreover, there was an energy transfer between the two SM acceptors, favorable for enhancing charge separation and transfer as well as reducing charge recombination at PBDB-T:IT-M and PBDB-T:DTF-IC interface. Simultaneously, HOMO and LUMO energy levels of DTF-IC were lower than those of PBDB-T, but still higher than those of IT-M. Thus, DTF-IC is able to provide a cascading energy level with the host donor and acceptor which are beneficial for efficient charge transfer between the acceptors and facilitating exciton dissociation and carrier transport. Meanwhile, the highly crystalline DTF-IC as a third component can improve the crystallization process of the active layer while maintaining proper phase separation. This work proposes a novel idea for non-fullerene acceptors achieved via twin spiro-type structure modifying by indanone and provides a new direction for the selection of ternary solar cell materials. | Lirong Wu Lingchao Xie Hanmin Tian Ruixiang Peng Jiaming Huang Billy Fanady Wei Song Songting Tan Wengang Bi Ziyi Ge | 2019 | Science Bulletin2019，64，15： | 0 |
