| 1 | CapOX as neoadjuvant chemotherapy for locally advanced operable colon cancer patients: a prospective single-arm phase Ⅱ trial显示文摘Objective: The aim of this prospective, single-arm phase II trial was to confirm the safety and efficacy of neoadjuvant chemotherapy(NAC) using oxaliplatin plus capecitabine(Cap OX) for patients with operable locally advanced colon cancer(CC).Methods: Patients with computed tomography-defined T4 or lymph node-positive CCs were enrolled. After radiological staging, patients were treated with at least 2 cycles of NAC consisting of 130 mg/m2 oxaliplatin on d 1,plus 1,000 mg/m2 capecitabine twice daily for 14 d every 3 weeks, followed by surgery, and then with the rest cycles of adjuvant chemotherapy. Radiological response was evaluated after 2 cycles of NAC. Tumor response, treatment toxicity, and surgical complications were recorded. The pathological response to therapy was evaluated according to the tumor regression grade(TRG) score. The primary endpoint was pathologic tumor response. This trial is registered in Clinical Trials.gov(No: NCT02415829).Results: Forty-seven patients were enrolled in the study. Forty-two patients completed the planned treatments.The total radiological response rate was 68%(32/47), including complete and partial response rates of 2%(1/47)and 66%(31/47), respectively. Stable disease was observed in 32%(15/47) and progressive disease was observed in none. Complete pathologic response, major regression, and at least moderate regression were achieved in 1(2%), 2(4%), and 29(62%) patients, respectively. Four patients developed grade 3 treatment toxicities. One patient with wound infection occurred after operation(1/47, 2%). There was no treatment-related death.Conclusions: Our results suggest that NAC with Cap OX is an effective and safe treatment option for patients with locally advanced CCs. | Fangqi Liu Li Yang Yuchen Wu Cong Li Jiang Zhao Adili Keranmu Hongtu Zheng Dan Huang Lei Wang Tong Tong Junyan Xu Ji Zhu Sanjun Cai Ye Xu | 2016 | Chinese Journal of Cancer Research2016，28，6： | 14 |
| 2 | Salt-assisted chemical vapor deposition of two-dimensional materials显示文摘Two-dimensional(2D) materials with atomic thickness are promising candidates for the applications in future semiconductor devices, owing to their fascinating physical properties and superlative optoelectronic performance. Chemical vapor deposition(CVD) is considered to be an efficient method for large-scale preparation of 2D materials toward practical applications.However, the high melting points of metal precursors and the thermodynamics instabilities of metastable phases limit the direct CVD synthesis of plenty of 2D materials. The salt has recently been introduced into the CVD process, which proved to be effective to address these issues. In this review, we highlighted the latest progress in the salt-assisted CVD growth of 2D materials, including layered and non-layered crystals. Firstly, strategies of adding salts are summarized. Then, the salt-assisted growth of various layered materials is presented, emphasizing on the transition metal chalcogenides of stable and metastable phases. Furthermore, strategies to grow ultrathin non-layered materials are discussed. We provide viewpoints into the techniques of using salt, the effects of salt, and the growth mechanisms of 2D crystals. Finally, we offer the challenges to be overcome and further research directions of this emerging salt-assisted CVD technique. | Wei Han Kailang Liu Sanjun Yang Fakun Wang Jianwei Su Bao Jin Huiqiao Li Tianyou Zhai | 2019 | Science China Chemistry2019，62，10： | 8 |

| 4 | Approaching ohmic contact to two-dimensional semiconductors显示文摘Two-dimensional semiconductors have attracted immense research interests owing to their intriguing properties and promising applications in electronic and optoelectronic devices.However,the performance of these devices is drastically hindered by the large Schottky barrier at the electric contact interface,which is hardly tunable due to the Fermi level pinning effect.In this review,we will analyze the root causes of the contact problems for the two-dimensional semiconductor devices and summarize the strategies on the basis of different contact geometries,aiming to lift out the Fermi level pinning effect and achieve the ohmic contact.Moreover,the remarkable improvement of the device performance thanks to these optimized contacts will be emphasized.At the end,the merits and limitations of these strategies will be discussed as well,which potentially gives a guideline for handling the electric contact issues in two-dimensional semiconductors devices. | Kailang Liu Peng Luo Wei Han Sanjun Yang Shasha Zhou Huiqiao Li Tianyou Zhai | 2019 | Science Bulletin2019，64，19： | 2 |
| 5 | Ultra-broadband,fast,and polarization-sensitive photoresponse of low-symmetry 2D NdSb_(2)显示文摘Broadband photodetectors with polarization-sensitive ability have received extraordinary attention for modern optoelectronic devices.Ideal photodetectors should possess high responsivity,fast response,and good stability,which are rare to meet at the same time in one low-symmetric two-dimentional(2D)material.In this work,neodymium diantimonides(RSb_(2)),a member of light rare-earth diantimonides RSb_(2)(R=La–Nd,Sm)with low-symmetry structure,is introduced as a fascinating highly anisotropic 2D material for broadband detection(532 nm to 4μm).The photodetector exhibits a responsivity of 0.49 mA·W^(−1)with 15μs response time at 532 nm and highly stable performance under ambient conditions over 8 months.Furthermore,we identify the polarization-sensitive photoresponse of the detector and demonstrate a high anisotropic factor~1.6.In addition,strong inplane anisotropy is revealed by anisotropic phonon response and the photodetection mechanism is investigated by scanning photocurrent microscopy measurements.This pioneer work on RSb_(2)paves the way for further exploration of 2D RSb_(2)for high performance polarized photodetectors with fast photothermoelectric response. | Gang Li Hanlin Zhang Yong Li Shiqi Yin Xucai Kan Wensen Wei Haifeng Du Binghui Ge Chao An Mingliang Tian Feng Yan Sanjun Yang Tianyou Zhai Liang Li | 2022 | Nano Research2022，15，6： | 1 |
| 6 | A Universal Atomic Substitution Conversion Strategy Towards Synthesis of Large‑Size Ultrathin Nonlayered Two‑Dimensional Materials显示文摘Nonlayered two-dimensional(2D)materials have attracted increasing attention,due to novel physical properties,unique surface structure,and high compatibility with microfabrication technique.However,owing to the inherent strong covalent bonds,the direct synthesis of 2D planar structure from nonlayered materials,especially for the realization of large-size ultrathin 2D nonlayered materials,is still a huge challenge.Here,a general atomic substitution conversion strategy is proposed to synthesize large-size,ultrathin nonlayered 2D materials.Taking nonlayered CdS as a typical example,large-size ultrathin nonlayered CdS single-crystalline flakes are successfully achieved via a facile low-temperature chemical sulfurization method,where pre-grown layered CdI2 flakes are employed as the precursor via a simple hot plate assisted vertical vapor deposition method.The size and thickness of CdS flakes can be controlled by the CdI2 precursor.The growth mechanism is ascribed to the chemical substitution reaction from I to S atoms between CdI2 and CdS,which has been evidenced by experiments and theoretical calculations.The atomic substitution conversion strategy demonstrates that the existing 2D layered materials can serve as the precursor for difficult-to-synthesize nonlayered 2D materials,providing a bridge between layered and nonlayered materials,meanwhile realizing the fabrication of large-size ultrathin nonlayered 2D materials. | Mei Zhao Sijie Yang Kenan Zhang Lijie Zhang Ping Chen Sanjun Yang Yang Zhao Xiang Ding Xiaotao Zu Yuan Li Yinghe Zhao Liang Qiao Tianyou Zhai | 2021 | Nano-Micro Letters2021，13，11： | 1 |

Besides, the glass-forming region of Ge S2-Ga2S3-Li2 S system was further studied by the conventional melt-quenching method.Ge S2-Ga2S3-Li2 S glass-ceramics containing IR Li2Ga2 Ge S6 nonlinear nanocrystals were obtained at a more carefully controlled heating rate. | 宋满 刘启明 TAN Min CHEN Ruiqi YANG Sanjun | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，3： | 0 |
| 8 | Novel Low-Complexity Low-Latency Orthogonal Frequency Division Multiplexing Transmitter显示文摘Traditional orthogonal frequency division multiplexing(OFDM) transmitter is implemented by exploiting inverse fast Fourier transform(IFFT), up-sampling, and low pass shaping filter(LPSF) modules, which occupy a large number of hardware resources and severely lower down the operation speed. To address these limitations, we propose a novel OFDM transmitter architecture, by which the aforementioned modules can be discarded and replaced with some simple switches. In the proposed architecture, direct digital synthesis(DDS) method is employed to generate digital sub-carriers and to transform OFDM data from frequency domain to time domain. Through some sophisticated simplifications, the proposed architecture can avoid using multipliers and remarkably save hardware resources. Finally, comparative experiments are carried out on field programmable gate array(FPGA) platform which demonstrates that our DDS-based architecture saves more than half of the hardware resources and doubles the achievable maximum frequency compared with traditional structure. | LIU Sanjun HUANG Shuanglin LI Min DONG Xiaojie QIU Da YANG Rui | 2019 | Wuhan University Journal of Natural Sciences2019，24，1： | 0 |
| 9 | PTPRO represses colorectal cancer tumorigenesis and progression by reprogramming fatty acid metabolism显示文摘Background:Abnormal expression of protein tyrosine phosphatases(PTPs)has been reported to be a crucial cause of cancer.As a member of PTPs,protein tyrosine phosphatase receptor type O(PTPRO)has been revealed to play tumor suppressive roles in several cancers,while its roles in colorectal cancer(CRC)remains to be elucidated.Hence,we aimed to explore the roles and mechanisms of PTPRO in CRC initiation and progression.Methods:The influences of PTPRO on the growth and liver metastasis of CRC cells and the expression patterns of different lipid metabolism enzymes were evaluated in vitro and in vivo.Molecular and biological experiments were conducted to uncover the underpinning mechanisms of dysregulated de novo lipogenesis and fatty acidβ-oxidation.Results:PTPRO expression was notably downregulated in CRC liver metastasis compared to the primary cancer,and such a downregulation was associated with poor prognosis of patients with CRC.PTPRO silencing significantly promoted cell growth and liver metastasis.Compared with PTPRO wild-type mice,PTPROknockout mice developed more tumors and harbored larger tumor loads under treatment with azoxymethane and dextran sulfate sodium.Gene set enrichment analysis revealed that PTPRO downregulation was significantly associated with the fatty acid metabolism pathways.Blockage of fatty acid synthesis abrogated the effects of PTPRO silencing on cell growth and liver metastasis.Further experiments indicated that PTPRO silencing induced the activation of the AKT serine/threonine kinase(AKT)/mammalian target of rapamycin(mTOR)signaling axis,thus promoting de novo lipogenesis by enhancing the expression of sterol regulatory element-binding protein 1(SREBP1)and its target lipogenic enzyme acetyl-CoA carboxylase alpha(ACC1)by activating the AKT/mTOR signaling pathway.Furthermore,PTPRO attenuation decreased the fatty acid oxidation rate by repressing the expression of peroxisome proliferator-activated receptor alpha(PPARα)and its downstream enzyme peroxisomal acyl-coenzyme A oxidase 1(ACOX1)via activating the p38/extracellular signal-regulated kinase(ERK)mitogen-activated protein kinase(MAPK)signaling pathway.Conclusions:PTPRO could suppress CRC development and metastasis via modulating the AKT/mTOR/SREBP1/ACC1 and MAPK/PPARα/ACOX1 pathways and reprogramming lipid metabolism. | Weixing Dai Wenqiang Xiang Lingyu Han Zixu Yuan Renjie Wang Yanlei Ma Yongzhi Yang Sanjun Cai Ye Xu Shaobo Mo Qingguo Li Guoxiang Cai | 2022 | Cancer Communications2022，42，9： | 0 |
