| 1 | Famitinib in combination with concurrent chemoradiotherapy in patients with locoregionally advanced nasopharyngeal carcinoma: a phase 1, open-label, dose-escalation Study显示文摘Background:Famitinib is a tyrosine kinase inhibitor against multiple targets,including vascular endothelial growth factor receptor 2/3,platelet-derived growth factor receptor,and stem cell factor receptor(c-kit).Previous studies have demonstrated anti-tumour activities of famitinib against a wide variety of advanced-stage solid cancers.We aimed to determine the safety and efficacy of famitinib with concurrent chemoradiotherapy(CCRT)in patients with locoregionally advanced nasopharyngeal carcinoma(NPC).We also evaluated the feasibility of contrast-enhanced ultrasound(D-CEUS)as a predictor of early tumour response to famitinib and to correlate functional parameters with clinical efficacy.Methods:The trial was conducted in subjects with stage III or IVa-b NPC using a 3+3 design of escalating fami-tinib doses.Briefly,subjects received 2 weeks of famitinib monotherapy followed by 7 weeks of famitinib plus CCRT.D-CEUS of the neck lymph nodes was performed at day 0,8 and 15 after famitinib was administered before starting concurrent chemoradiotherapy.End points included safety,tolerability and anti-tumour activity.Results:Twenty patients were enrolled(six each for 12.5,16.5 and 20 mg and two for 25 mg).Two patients in the 25 mg cohort developed dose-limiting toxicities,including grade 4 thrombocytopenia and grade 3 hypertension.The most common grade 3/4 adverse events were leukopenia,neutropenia and radiation mucositis.D-CEUS tests showed that more than 60%of patients achieved a perfusion parameter response after 2 weeks taking famitinib alone,and the parameter response was associated with disease improvement.In the famitinib monotherapy stage,three patients(15%)showed partial responses.The complete response rate was 65%at the completion of treatment and 95%3 months after the treatment ended.After a median follow-up of 44 months,the 3-year progression-free survival(PFS)and distant metastasis-free survival were 70%and 75%,respectively.Subjects with a decrease of perfusion parameter response,such as peak intensity decreased at least 30%after 1 week of famitinib treatment,had higher 3-year PFS(90.9%vs.44.4%,95%CI 73.7%-100%vs.11.9%-76.9%,P<0.001)than those with an increase or a reduction of less than 30%.Conclusions:The recommended famitinib dose for phase II trial is 20 mg with CCRT for patients with local advanced NPC.D-CEUS is a reliable and early measure of efficacy for famitinib therapies.Further investigation is required to confirm the effects of famitinib plus chemoradiotherapy. | Qiuyan Chen Linquan Tang Na Liu Feng Han Ling Guo Shanshan Guo Jianwei Wang Huai Liu Yanfang Ye Lu Zhang Liting Liu Pan Wang Yingqin Li Qingmei He Xiaoqun Yang Qingnan Tang Yang Li YuJing Liang XueSong Sun Chuanmiao Xie Yunxian Mo Ying Guo Rui Sun Haoyuan Mo Kajia Cao Xiang Guo Musheng Zeng Haiqiang Mai Jun Ma | 2018 | Cancer Communications2018，38，1： | 6 |
| 2 | Hybrid nano-scale Au with ITO structure for a high-performance near-infrared silicon-based photodetector with ultralow dark current显示文摘An internal photoemission-based silicon photodetector detects light below the silicon bandgap at room temperature and can exhibit spectrally broad behavior,making it potentially suited to meet the need for a near-infrared pure Si photodetector.In this work,the implementation of a thin Au insertion layer into an ITO/n-Si Schottky photodetector can profoundly affect the barrier height and significantly improve the device performance.By fabricating a nanoscale thin Au layer and an ITO electrode on a silicon substrate,we achieve a well-behaved ITO/Au/n-Si Schottky diode with a record dark current density of 3.7×10^(−7) A/cm^(2) at−1 V and a high rectification ratio of 1.5×10^(8) at±1 V.Furthermore,the responsivity has been obviously improved without sacrificing the dark current performance of the device by decreasing the Au thickness.Such a silicon-based photodetector with an enhanced performance could be a promising strategy for the realization of a monolithic integrated pure silicon photodetector in optical communication. | Xinxin Li Zhen Deng Jun Li Yangfeng Li Linbao Guo Yang Jiang Ziguang Ma Lu Wang Chunhua Du Ying Wang Qingbo Meng Haiqiang Jia Wenxin Wang Wuming Liu Hong Chen | 2020 | Photonics Research2020，8，11： | 4 |
| 3 | Complete entanglement analysis on electron spins using quantum dot and microcavity coupled system显示文摘We present an entanglement analysis protocol on entangled electron spins using quantum dot(QD)and microcavity coupled system.Each quantum dot is placed in the microcavity and ancilla photon input-output process could be used to check the parity of the quantum dots.After the parity check process,the user only needs to measure the spin direction of the QD spin,and the state information can be readout completely.The feasibility of our scheme and the experimental challenge are discussed by considering currently available techniques. | WANG Chuan HE LingYan ZHANG Yong MA HaiQiang ZHANG Ru | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 4 |
| 4 | Dynamic single-index model for functional data显示文摘We propose a new functional single index model, which called dynamic single-index model for functional data, or DSIM, to efficiently perform non-linear and dynamic relationships between functional predictor and functional response. The proposed model naturally allows for some curvature not captured by the ordinary functional linear model. By using the proposed two-step estimating algorithm, we develop the estimates for both the link function and the regression coefficient function, and then provide predictions of new response trajectories. Besides the asymptotic properties for the estimates of the unknown functions, we also establish the consistency of the predictions of new response trajectories under mild conditions. Finally, we show through extensive simulation studies and a real data example that the proposed DSIM can highly outperform existed functional regression methods in most settings. | MA HaiQiang BAI Yang ZHU ZhongYi | 2016 | Science China Mathematics2016，59，12： | 2 |
| 5 | Is 1.28 parts per million biomarker specific for neural progenitor cells?显示文摘Nuclear magnetic resonance-visible mobile lipid,at 1.28 parts per million(ppm),is thought to be due to mobile lipid droplets formed in cells and has been considered unique for neural progenitor cells.However,this idea remains controversial.The present study examined the 1.28 ppm biomarker in other stem cells and non-stem cells,and explored the relationship between 1.28 ppm biomarker and mobile lipid droplets.1H nuclear magnetic resonance spectroscopy of EC109 cells,mesenchymal stem cells(MSCs) and adipogenic cells differentiated from MSCs was performed.Results show that 1.28 ppm biomarker was observed in human MSCs,but was absent from EC109 cells.Following adipogenic differentiation induced for 2 weeks,the 1.28 ppm biomarker climbed remarkably,with mobile lipid droplet generation,suggesting that the 1.28 ppm biomarker is not specific for neural progenitor cells because it is also observed in MSCs and adipogenic-induced differentiated cells.Moreover,it is possible to monitor MSCs differentiation following cell transplantation,using 1.28 ppm biomarker changes. | Zhifeng Xu Chongyang Shen Haiqiang Zhu Yaowen Chen Linping Wu Peng Huang YeyuXiao Zhiwei Shen Li Pang Xiuqin Guo Lian Ma Renhua Wu | 2010 | Neural Regeneration Research2010，5，15： | 2 |
| 6 | Thermoelectric properties of In-substituted Ge-based clathrates prepared by HPHT显示文摘Bulk materials Ba_(8)Ga_(16)In_(x)Ge_(30-x)(x=0.5,1.0,1.5)were prepared by High-Pressure and High-Temperature(HPHT)method and the crystal structure has been confirmed by X-ray diffraction and cell refinement.The actual In composition was much lower than the starting composition,and lattice constants increased with the increase of substitution.As the temperature increased,the Seebeck coefficient and electrical resistivity increased first and then decreased,while the thermal conductivity was the opposite,which leads to significant enhancement on thermoelectric properties of the clathrates.The substitution of indium elements decreased the seebeck coefficient and electrical resistivity,and also changed the microstructure of the compounds.A minimum thermal conductivity of 0.84Wm^(-1)1K^(-1)was obtained,and a good ZT value of 0.52 was achieved.The grain boundaries and lattice defects generated by high pressure can effectively scatter phonons of different frequencies,which reduce the lattice thermal conductivity. | Binwu Liu Hongan Ma Dexuan Huo Haiqiang Liu Baomin Liu Jiaxiang Chen Xiaopeng Jia | 2018 | Journal of Materiomics2018，4，1： | 1 |
| 7 | High-thermoelectric performance of TiO_(2-x)fabricated under high pressure at high temperatures显示文摘We present the work about the initiative fabrication of multi-scale hierarchical TiO2-x by our strategy,combining high pressure and high temperature(HPHT)reactive sintering with appropriate ratio of coarse Ti to nanosized TiO_(2).Ubiquitous lattice defects engineering has also been achieved in our samples by HPHT.The thermoelectric performance was significantly enhanced,and rather low thermal conductivity(1.60 W m^(-1)K^(-1))for titanium oxide was reported here for TiO1.76.Correspondingly,a high dimensionless figure of merit(zT)up to 0.33 at 700℃was realized in it.As far as we know,this value is an enhancement of 43%of the ever best result about nonstoichiometric TiO_(2)and the result is also exciting for oxide thermoelectric materials.The moderate power factor,the significantly reduced thermal conductivity and the remarkable synergy between electrical properties and thermal conductivity are responsible for the excellent thermoelectric performance.We develop a facile strategy for preparing multi-scale hierarchical TiO_(2-x)and its superior ability to optimize thermoelectric performance has been demonstrated here. | Haiqiang Liu Hongan Ma Taichao Su Yuewen Zhang Bing Sun Binwu Liu Lingjiao Kong Baomin Liu Xiaopeng Jia | 2017 | Journal of Materiomics2017，3，4： | 1 |

| 9 | The impact of nanoporous SiN_x interlayer growth position on high-quality GaN epitaxial films显示文摘The impact of nanoporous SiN x interlayer growth position on high-quality GaN epitaxial film was elucidated from the behavior of dislocations. The best quality GaN film was achieved when a nanoporous SiN x interlayer was grown on a rough layer, with the high-resolution X-ray diffraction rocking curve full width at half maximum for ( 1102 ) reflection decreasing to 223 arcs, and the total dislocation density reduced to less than 1.0×10 8 cm 2 . GaN films were grown on sapphire substrates by metal organic chemical vapor deposition. The quality of these films was investigated with high-resolution X-ray diffraction, atomic force microscopy, and cross-sectional transmission electron microscopy. A preference for the formation of half-loops to reduce threading dislocations was observed when an SiN x interlayer was grown on a rough layer. A growth mechanism is proposed to explain this preference. | MA ZiGuang XING ZhiGang WANG XiaoLi CHEN Yao XU PeiQiang CUI YanXiang WANG Lu JIANG Yang JIA HaiQiang CHEN Hong | 2011 | Chinese Science Bulletin2011，56，25： | 0 |
| 10 | The influence of pressure on the growth of a-plane GaN on r-plane sapphire substrates by MOCVD显示文摘Nonpolar a-plane (110) GaN films have been grown on r-plane (102) sapphire by metal-organic chemical vapor deposition (MOCVD) under different growth pressures. The as-grown films are investigated by optical microscopy, high-resolution X-ray diffraction (HRXRD) and Raman scattering. As growth pressure rises from 100 mbar to 400 mbar, the surface gets rougher, and the in-plane XRD full width at half maximum (FWHM) along the c-axis [0001] increases while that along the m-axis [100] decreases. Meanwhile, residential stresses are reduced along both the c-axis and the m-axis. The structural anisotropy feature under 400 mbar is inverted with respect to 100 mbar, and the weakened anisotropy is achieved under a moderate pressure of 200 mbar, probably due to the suppressed Ga atomic migration along the c-axis under a larger pressure. We propose that pressure can affect a-plane growth through the V/III ratio. | HE Tao LI Hui DAI LongGui WANG XiaoLi CHEN Yao MA ZiGuang XU PeiQiang JIANG Yang WANG Lu JIA HaiQiang WANG WenXin CHEN Hong | 2011 | Science China(Physics,Mechanics & Astronomy)2011，54，3： | 0 |
| 11 | Composite double-layer microneedle loaded with traditional Chinese medicine for the treatment of androgenic alopecia显示文摘Androgenetic alopecia(AGA)is an androgen-mediated alopecia affected by both genes and hormones.Medication is a relatively common treatment.As a new drug delivery method,microneedles(MNs)can effectively break through the stratum corneum barrier,deliver drugs more efficiently,and achieve better therapeutic effects.In this study,we develop a composite double-layer MN through multi-step casting fabrication using a polydimethylsiloxane mold.The needle tip was fabricated by mixed solution of chitosan and polyvinylpyrrolidone which was loaded with Polygonum multiflorum extract,and the base layer was prepared by mixed solution of polyvinyl alcohol and polyvinylpyrrolidone.In vitro mechanical tests showed that the maximum load of a single tip of the drug-loaded MN was about 3.5 N,which met the mechanical requirements of skin puncture(>1 N).The drug release experiment showed that the MN could achieve gradual drug release.In the animal experiment,pigmentation and hair regrowth occurred earlier in the Polygonum multiflorum-MN(Pm-MN)group than in the other groups,and hair growth finally appeared in almost the entire area.Compared with the AGA model mice,mice in the Pm-MN group achieved an increase in the number and diameter of hair follicles.In conclusion,the Pm-MN is scientific and feasible for treating AGA. | Ruoxi Wang Jiangge Wang Haiqiang Gao Xiangyi Liao Chunyang Ma Xufeng Niu | 2023 | Medicine in Novel Technology and Devices2023，，2： | 0 |
