| 1 | Downstaging and resection of hepatocellular carcinoma in patients with extrahepatic metastases after stereotactic therapy显示文摘Background:A combination of tyrosine kinase inhibitors(TKIs)and anti-PD-1 antibodies with local regional therapy has elicited yield substantial clinical benefits in patients who have hepatocellular carcinoma(HCC)with extrahepatic metastases.Using this treatment strategy to convert HCC patients with extrahepatic metastases from unresectable to resectable has not yet been reported.Methods:Consecutive hepatocellular carcinoma patients with extrahepatic metastases who received first-line therapy with a combination of TKIs and anti-PD-1 antibodies and at least one local regional therapy were analysed.Results:Nine patients with localized disease who received first-line systemic therapy were enrolled.At baseline,all of them had oligometastatic disease,namely,Barcelona Clinic Liver Cancer stage C(or Chinese Liver Cancer stage IIIB).The most common treatment administered was lenvatinib plus anti-PD-1 antibody and transarterial chemoembolization,and the median time span from systemic therapy to surgery was 3.2(IQR,2.8-6.2)months.Three patients achieved a pathological complete response.Six patients underwent laparoscopic surgery,and the other 3 patients underwent open surgery.After a median follow-up of 10.2(IQR,8.6-20.0)months,7 patients survived without disease recurrence,and 2 experienced tumour recurrence.All patients had any-grade AEs,and 55.6%of the patients experienced grade 3 AEs.Fatigue was the most common AE,followed by elevated aminotransferase levels and hypertension.Conclusions:Stereotactic therapy is a feasible conversion therapy for HCC patients with extrahepatic metastases to become resectable.This is the first study to analyse therapeutic outcomes of patients receiving these therapies for HCC with extrahepatic metastases. | Xiaobo Yang Haifeng Xu Bangyou Zuo Xu Yang Jin Bian Junyu Long Dongxu Wang Junwei Zhang Cong Ning Yanyu Wang Ziyu Xun Yunchao Wang Xin Lu Yilei Mao Xinting Sang Haitao Zhao | 2021 | Hepatobiliary Surgery and Nutrition2021,10,4: | 17 |
| 2 | Highly stable lead-free Cs3Bi2I9 perovskite nanoplates for photodetection applications显示文摘Lead halide perovskites have received tremendous attentions recently for their excellent properties such as high light absorption coefficient and long charge carrier diffusion length. However, the stability issues and the existence of toxic lead cations have largely limited their applications in optoelectronic area. Herein, we report the synthesis and investigation of highly stable and lead-free Cs3Bi2I9 perovskite nanoplates for visible light photodetection applications. The Cs3Bi2I9 nanoplates were synthesized through a facile solution-processed method, which is also applicable to various substrates. The achieved nanoplates present very good crystal quality and exhibit excellent long-term stability even exposed in moist air for several months. Photodetectors were constructed based on these high-quality perovskite nanoplates for the first time, and display a maximum photoresponsivity of 33.1 mA/W under the illumination of 450 nm laser, which is six times higher than the solution-synthesized CH3NH3PbI3 nanowire photodetectors. The specific detectivity of these devices can reach up to 10^10 Jones. Additionally, the devices exhibit fast rise and decay time of 10.2 and 37.2 ms, respectively, and highly stable photoswitching behavior with their photoresponse well retaining under alternating light and darkness. This work opens up a new opportunity for stable and low-toxic perovskite-based optoelectronic applications. | Zhaoyang Qi Xianwei Fu Tiefeng Yang Dong Li Peng Fan Honglai Li Feng Jiang Lihui Li Ziyu Luo Xiujuan Zhuang Anlian Pan | 2019 | Nano Research2019,12,8: | 7 |
| 3 | Uniform corrosion behavior of FeCrAl alloys in borated and lithiated high temperature water显示文摘The uniform corrosion behavior of model FeCrAl alloys as well as commercial Zircaloy-4 as reference material were investigated in 360℃borated and lithiated water.The results reveal that FeCrAl alloys exhibited better corrosion resistance than Zircaloy-4.It is found that the oxide films formed on the FeCrAl alloys are composed of outer Fe_(3)O_(4)layer,inner layer consisting of compact spinel layer and porous spinel layer,and transition layer containing Al-Cr-rich oxides and matrix enriched with Fe°.The spinel oxides in the inner layer are FeFe_(2-x-y-z)Cr_(x)Al_(y)MozO_(4).The corrosion mechanism of FeCrAl alloys in high temperature water is discussed. | Fangqiang Ning Xiang Wang Ying Yang Jibo Tan Ziyu Zhang Dan Jia Xinqiang Wu En-Hou Han | 2021 | Journal of Materials Science & Technology2021,,11: | 6 |
| 4 | Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery. | Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji | 2018 | Chinese Journal of Cancer Research2018,30,5: | 5 |
| 5 | The five major autoimmune diseases increase the risk of cancer:epidemiological data froma large-scale cohort study in China显示文摘Background:Cancer incidence and mortality have received critical attention during the long-term management of morbidities in patients with autoimmune diseases(AIDs).This study aimed to investigate and compare the risk of cancer associated with five major AIDs in a large-scale Chinese cohort.Methods:A total of 8,120 AID patients consecutively admitted to a national tertiary referral center in China were included and followed-up for 38,726.55 patient-years,including those with systemic lupus erythematosus(SLE),rheumatoid arthritis(RA),Sjoren’s syndrome(SS),systemic scleroderma(SSc),and idiopathic inflammatory myositis(IIM).Demographic data,cancer incidence,predilecting sites and cancer onset time were recorded and compared among the five AIDs.Results:Four hundred and thirty(5.3%)patients developed cancer.Their median agewas 57.5 years and AID durationwas 79.8 months.The estimated total standardized incidence ratio(SIR)of cancer in AIDs patients was 3.37,with the highest SIR observed in IIM(4.31),followed by RA(3.99),SSc(3.77),SS(2.88)and SLE(2.58).The increased SIR of cancers in AID patients showed a female predominance(female vs.male:3.59 vs.2.77)and younger patient involvement(age<50 vs.≥50 years:4.88 vs.3.04).Patientswith SLE had increased SIRs for developing hematologic malignancies and solid tumors located in the urinary bladder,corpus uteri and cervix uteri.Patients with SS had a significantly high SIR for developing non-Hodgkin’s lymphoma.Within 3 years of IIM diagnosis,74.6%of the patients developed cancer and they had a high risk of ovarian cancer.RA was associated with a wide distribution of scancers,including non-Hodgkin’s lymphoma,gynecologic,urinary tract,thyroid gland and lung cancers.SSc patients had increased SIRs for developing cervical uterine,lung,and breast cancers.Conclusion:Patients with five major AIDs in China had an increased risk of developing cancer,with a predominance in women and younger patients,although cancer incidence,predilection sites and cancer onset time may vary greatly in each AID entity. | Ziyue Zhou Huazhen Liu Yiying Yang Jingya Zhou Lidan Zhao Hua Chen Yunyun Fei Wen Zhang Mengtao Li Yan Zhao Xiaofeng Zeng Fengchun Zhang Huaxia Yang Xuan Zhang | 2022 | Cancer Communications2022,42,5: | 4 |

| 7 | Porous cobalt oxide nanowires: Notable improved gas sensing performances显示文摘The porous Co3O4 nanowires have been successfully synthesized via modified template method. A possible growth mechanism governing the formation of such 1D nanowires is proposed. The as-prepared products have been characterized by X-ray Powder Diffraction (XRD), Extended X-ray Absorption Fine-structure (EXAFS), High-resolution Transmission Electron Microscopy (HRTEM) and N2 adsorption/desorption analysis. Our systematic studies have revealed that the porous Co3O4 nanowires show excellent gas sensing performances, which demonstrate the potential application of the 1D nanostructured Co3O4 in the detection of the ethanol gas as a sensor material. The improved performances are owing to its large specific surface area and porous morphology. | MA MaiXia PAN ZhiYun GUO Lin LI JingHong WU ZiYu YANG ShiHe | 2012 | Chinese Science Bulletin2012,57,31: | 4 |
| 8 | A 70 Gbps NRZ optical link based on 850 nm band-limited VCSEL for data-center intra-connects显示文摘Short-reach optical interconnects among servers in data centers have attracted extensive studies recently. High capacity and low cost are two key problems for optical link. In this paper, we demonstrate a band-limited 850 nm vertical cavity surface emitting laser(VCSEL) based optical transmission system. The optical link realizes 70 Gb/s(65 Gb/s net rate) non-return-to-zero(NRZ) signal transmission over 11 m and20 m OM4 multimode fiber(MMF), with the help of equalization for time domain interference elimination.The utilized VCSEL has a bandwidth of only 18 GHz, meeting the principle of low cost. The data baud rate in this paper reaches the highest value for an 18-GHz-class 850 nm VCSEL based optical link, to our best knowledge. | Zhongwei TAN Chuanchuan YANG Yixiao ZHU Zhaopeng XU Kaiheng ZOU Fan ZHANG Ziyu WANG | 2018 | Science China(Information Sciences)2018,61,8: | 3 |
| 9 | Plasmonically engineered light-matter interactions in Aunanoparticle/MoS_(2) heterostructures for artificial optoelectronic synapse显示文摘Optoelectronic synaptic elements are emerging functional devices for the vigorous development of advanced neuromorphic computing technology in the post-Moore era.However,optoelectronic devices based on transition metal dichalcogenides(TMDs)are limited to their poor mobilities and weak light-matter interactions,which still hardly exhibit superior device performances in the application of artificial synapses.Here,we demonstrate the successful fabrication of Au nanoparticle-coupled MoS_(2)heterostructures via chemical vapor deposition(CVD),where the light absorption of MoS_(2)is greatly enhanced and engineered by plasmonic effects.Hot electrons are excited from Au nanoparticles,and then injected into MoS_(2)semiconductors under the light illumination.The plasmonically-engineered photo-gating effect at the metal-semiconductor junction is demonstrated to create optoelectronic devices with excellent synaptic behaviors,especially in ultra-sensitive excitatory postsynaptic current(EPSC,9.6×10^(-3)nA@3.4 nW·cm^(-2)),ultralow energy consumption(34.7 pJ),long-state retention time(>1,000 s),and tunable synaptic plasticity transitions.The material system of Au-nanoparticles coupled TMDs presents unique advantages for building artificial synapses,which may lead the future development of neuromorphic electronics in optical information sensing and learning. | Zhuoran Luo Yunfei Xie Ziwei Li Yajuan Wang Lihui Li Ziyu Luo Chenguang Zhu Xin Yang Ming Huang Jianhua Huang Delang Liang Xiaoli Zhu Dong Li Anlian Pan | 2022 | Nano Research2022,15,4: | 3 |
| 10 | Fabrication and performance evaluation of novel transparent ceramics RE:Tb_(3)Ga_(5)O_(12)(RE=Pr,Tm,Dy)toward magneto-optical application显示文摘Transparent ceramics are at the heart of modern magneto-optical materials providing promising opportunities for Faraday isolators.1.0 at%RE:Tb3Ga5O12(rare earth(RE)=Pr,Tm,Dy)transparent ceramics were successfully prepared by air sintering and sequential HIP technique using the coprecipitated powders as the raw material.All the powders have shown to be a pure cubic terbium gallium garnet(TGG)phase and exhibit good dispersion.Additionally,a change could not be observed in particle shape with the different doped ions.After the two-step sintering,all the obtained ceramics have good optical quality,and the in-line transmittances at 1070 nm are higher than 80%.Moreover,no secondary phase can be detected from the microstructures.However,the pores which remain entrapped in the ceramics can be noted.The Verdet constant of ceramic samples is optimized by RE doping,and the Verdet constant at 632.8 nm is about−143 rad·T^(−1)·m^(−1),which is about 5%higher than that of TGG ceramics.Finally,the thermo-optical properties of 1.0 at%RE:TGG transparent ceramics are compared.The annealed TGG ceramic showed the best thermo-optical properties,and the thermally induced depolarization of 1.0 at%Ce:TGG and 1.0 at%Tm:TGG was inferior to that of annealed TGG ceramic. | Xiaoying Li Ilya LSnetkov Aleksey Yakovlev Qiang Liu Xin Liu Ziyu Liu Penghui Chen Danyang Zhu Lexiang Wu Zhaoxiang Yang Tengfei Xie Haohong Chen Oleg Palashov Jiang Li | 2021 | Journal of Advanced Ceramics2021,10,2: | 3 |
| 11 | MBA:A market-based approach to data allocation and dynamic migration for cloud database显示文摘With the coming shift to cloud computing,cloud database is emerging to provide database service over the Internet.In the cloud-based environment,data are distributed at Internet scale and the system needs to handle a huge number of user queries simultaneously without delay.How data are distributed among the servers has a crucial impact on the query load distribution and the system response time.In this paper,we propose a market-based control method,called MBA,to achieve query load balance via reasonable data distribution.In MBA,database nodes are treated as traders in a market,and certain market rules are used to intelligently decide data allocation and migration.We built a prototype system and conducted extensive experiments.Experimental results show that the MBA method significantly improves system performance in terms of average query response time and fairness. | WANG TengJiao LIN ZiYu YANG BiShan GAO Jun HUANG Allena YANG DongQing ZHANG Qi TANG ShiWei NIU JinZhong | 2012 | Science China(Information Sciences)2012,55,9: | 2 |
| 12 | In vivo evaluation of additively manufacturedmulti-layered scaffold for the repair of large osteochondral defects显示文摘The repair of osteochondral defects is one of the major clinical challenges in orthopaedics.Well-established osteochondral tissue engineering methods have shown promising results for the early treatment of small defects.However,less success has been achieved for the regeneration of large defects,which is mainly due to the mechanical environment of the joint and the heterogeneous nature of the tissue.In this study,we developed a multi-layered osteochondral scaffold to match the heterogeneous nature of osteochondral tissue by harnessing additive manufacturing technologies and combining the established art laser sintering and material extrusion techniques.The developed scaffold is based on a titanium and polylactic acid matrix-reinforced collagen“sandwich”composite system.The microstructure and mechanical properties of the scaffold were examined,and its safety and efficacy in the repair of large osteochondral defects were tested in an ovine condyle model.The 12-week in vivo evaluation period revealed extensive and significantly higher bone in-growth in the multi-layered scaffold compared with the collagen–HAp scaffold,and the achieved stable mechanical fixation provided strong support to the healing of the overlying cartilage,as demonstrated by hyaline-like cartilage formation.The histological examination showed that the regenerated cartilage in the multi-layer scaffold group was superior to that formed in the control group.Chondrogenic genes such as aggrecan and collagen-II were upregulated in the scaffold and were higher than those in the control group.The findings showed the safety and efficacy of the cell-free“translation-ready”osteochondral scaffold,which has the potential to be used in a one-step surgical procedure for the treatment of large osteochondral defects. | Maryam Tamaddon Gordon Blunn Rongwei Tan Pan Yang Xiaodan Sun Shen-Mao Chen Jiajun Luo Ziyu Liu Ling Wang Dichen Li Ricardo Donate Mario Monzón Chaozong Liu | 2022 | Bio-Design and Manufacturing2022,5,3: | 2 |

| 14 | Slow light in tapered slot photonic crystal waveguide显示文摘A slotted single-mode photonic crystal waveguide with a linear tapered slot is presented to realize slow light,whose dispersion curve is shifted by changing the slot width.When the slot width is reduced,the band curve shifts in the tapered structure,and the group velocity of light approach zero at the cut-off frequency.Therefore,different frequency components of the guided light are slowed down even localized along the propagation direction inside a tapered slot photonic crystal waveguide.Furthermore,this structure can confine slow light-wave in a narrow slot waveguide,which may effectively enhance the interaction between slow light and the low-index wave-guiding materials filled in the slot.In addition,this tapered slot structure can be used to compensate group velocity dispersion of slow light by modifying the structure,thus opening the opportunity for ultra-wide bandwidth slow light. | WU Jun LI YanPing YANG ChuanChuan PENG Chao WANG ZiYu | 2009 | Chinese Science Bulletin2009,54,20: | 2 |

| 16 | Gastrin attenuates sepsis-induced myocardial dysfunction by down-regulation of TLR4 expression in macrophages显示文摘Myocardial dysfunction is the most serious complication of sepsis.Sepsis-induced myocardial dysfunction(SMD)is often associated with gastrointestinal dysfunction,but its pathophysiological significance remains unclear.The present study found that patients with SMD had higher plasma gastrin concentrations than those without SMD.In mice,knockdown of the gastrin receptor,cholecystokinin B receptor(Cckbr),aggravated lipopolysaccharide(LPS)-induced cardiac dysfunction and increased inflammation in the heart,whereas the intravenous administration of gastrin ameliorated SMD and cardiac injury.Macrophage infiltration plays a significant role in SMD because depletion of macrophages by the intravenous injection of clodronate liposomes,48 h prior to LPS administration,alleviated LPSinduced cardiac injury in Cckbr-deficient mice.The intravenous injection of bone marrow macrophages(BMMs)overexpressing Cckbr reduced LPS-induced myocardial dysfunction.Furthermore,gastrin treatment inhibited toll-like receptor 4(TLR4)expression through the peroxisome proliferator-activated receptor a(PPAR-a)signaling pathway in BMMs.Thus,our findings provide insights into the mechanism of the protective role of gastrin/CCKBR in SMD,which could be used to develop new treatment modalities for SMD. | Dandong Fang Yu Li Bo He Daqian Gu Mingming Zhang Jingwen Guo Hongmei Ren Xinyue Li Ziyue Zhang Ming Tang Xingbing Li Donghai Yang Chunmei Xu Yijie Hu Hongyong Wang Pedro AJose Yu Han Chunyu Zeng | 2023 | Acta Pharmaceutica Sinica B2023,13,9: | 1 |
