| 1 | Clinicopathological analysis of metaplastic meningioma: report of 15 cases in Huashan Hospital显示文摘Objective: Metaplastic meningioma is a rare subtype of benign meningiomas, classified as WHO grade I with well prognosis. Here we presented our experiences on 15 cases of metaplastic meningioma, to investigate the clinicopathological features, therapies and prognosis of these cases. Methods: 15 patients underwent surgical treatment for intracranial metaplastic meningioma between 2001 and 2010 at Neurosurgery Department of Huashan Hospital, Shanghai, China. The clinical data, radiological manifestation, treatment strategy, pathological findings and prognosis of all patients were analyzed retrospectively. Results: Among the 15 cases (10 males and 5 females), the age ranged from 22 to 74 years old (the mean age was 50.67-year old). The clinical manifestations include headache, dizziness, seizure attack, vision decrease, and weakness of bilateral lower limbs. All the patients received surgical treatment, combined with radiotherapy in some cases. In the follow-up period, recurrence occurred in 2 cases, of which 1 patient died of other system complications. Conclusions: Metaplastic meningiomas are characterized by focal or widespread mesenchymal differentiation with formation of bone, cartilage, fat, and xanthomatous tissue elements. Surgical removal is the optimal therapy, and the overall prognosis is well. But recurrence may occur in some cases, thus radiotherapy is necessary for such kind of patients. | Hailiang Tang Huaping Sun Hong Chen Ye Gong Ying Mao Qing Xie Liqian Xie Mingzhe Zheng Daijun Wang Hongda Zhu Xiaoming Che Ping Zhong Kang Zheng Shiqi Li Weimin Bao Jianhong Zhu Xuanchun Wang Xiaoyuan Feng Xiancheng Chen Liangfu Zhou | 2013 | Chinese Journal of Cancer Research2013，25，1： | 6 |
| 2 | Carbonaceous Nanofibers-titanium Dioxide Nanocomposites: Synthesis and Use as a Platform for Removal of Dye Pollutants显示文摘A mild chemistry route was developed to prepare carbonaceous nanofibers-titanium dioxide(CNF-TiO_2) nanocomposites for removal of dye pollutants. In the process of the template-directed hydrothermal carbonization(HTC), ultrathin Te nanowires were adopted as templates and glucose as the carbon source, and TiO_2 was decorated on CNF via the hydrolysis of tetrabutyltitanate in the presence of CNF in ethanol. The as-prepared materials were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), energy-dispersive X-ray(EDX) and X-ray diffraction(XRD). SEM and TEM observations displayed that TiO_2 nanoparticles were anchored on the CNF. EDX and XRD data confirmed that the assynthesized samples were CNF-TiO_2, and TiO_2 belonged to anatase titania. Taking advantage of combined benefits of carbonaceous nanofibers and titanium dioxide, these CNF-TiO_2 nanocomposites exhibited higher removal efficiency in a short time and showed good reusability. It was showed that over 97% of Rhodamine B could be removed in 15 min without generating the solid and liquid wastes. The removal efficiency of dyes was still over 80% after reuse in five cycles. All the results demonstrate that the as-prepared CNF-TiO_2 composites are effective materials for fast and effective removal of dye pollutants and thus can provide a new platform for dye decontamination. | 郭洪影 JIANG Shan WANG Chaoyuan LI Shenwan FENG Jianjian 孙红梅 ZHU Hongda GUO Huiling LIU Mingxing SUN Honghao | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，2： | 3 |
| 3 | Intraoperative ultrasound assistance in resection of intracranial meningiomas显示文摘Objective: Intracranial meningiomas, especially those located at anterior and middle skull base, are difficult to be completely resected due to their complicated anatomy structures and adjacent vessels. It's essential to locate the tumor and its vessels precisely during operation to reduce the risk of neurological deficits. The purpose of this study was to evaluate intraoperative ultrasonography in displaying intracranial meningioma and its surrounding arteries, and evaluate its potential to improve surgical precision and minimize surgical trauma. Methods: Between December 2011 and January 2013, 20 patients with anterior and middle skull base meningioma underwent surgery with the assistance of intraoperative ultrasonography in the Neurosurgery Department of Shanghai Huashan Hospital. There were 7 male and 13 female patients, aged from 31 to 66 years old. Their sonographic features were analyzed and the advantages of intraoperative ultrasonography were discussed. Results: The border of the meningioma and its adjacent vessels could be exhibited on intraoperative ultrasonography. The sonographic visualization allowed the neurosurgeon to choose an appropriate approach before the operation. In addition, intraoperative ultrasonography could inform neurosurgeons about the location of the tumor, its relation to the surrounding arteries during the operation, thus these essential arteries could be protected carefully. Conclusions: Intraoperative ultrasonography is a useful intraoperative technique. When appropriately applied to assist surgical procedures for intracranial meningioma, it could offer very important intraoperative information (such as the tumor supplying vessels) that helps to improve surgical resection and therefore might reduce the postoperative morbidity. | Hailiang Tang Huaping Sun Liqian Xie Qisheng Tang Ye Gong Ying Mao Qing Xie Mingzhe Zheng Daijun Wang Hongda Zhu Jianhong Zhu Xiaoyuan Feng Zhenwei Yao Xiancheng Chen Liangfu Zhou | 2013 | Chinese Journal of Cancer Research2013，25，3： | 3 |
| 4 | Engineering Broad-Spectrum Resistance to Bacterial Blight by CRISPR/Cas9-Mediated Precise Homology Directed Repair in Rice显示文摘Dear Editor,Rice(Oryza sativa)is one of the most important food crops as well as a model plant for basic research.Rice bacterial blight(BB)caused by Xanthomonas oryzae pv.oryzae(Xoo)is a devastating bacterial disease worldwide(Mew et al.,1993),affecting millions of hectares of rice annually,with an estimated crop loss of as high as 75%.Upon invasion of rice cells,Xoo secretes transcription activator-like effectors(TALEs)to activate the host Sugars Will Eventually be Exported Transporters(SWEET)genes to obtain nutrition for bacterial growth,because the induced SWEET transports more sugars to where the bacteria reside(Boch and Bonas,2010). | Zheng Wei Mohamed Abdelrahman Ying Gao Zhiyuan Ji Rukmini Mishra Hongda Sun Yi Sui Chuanyin Wu Chunlian Wang Kaijun Zhao | 2021 | Molecular Plant2021，14，8： | 3 |
| 5 | Preparation and Characterization of Carboxyl Functionalized Fluorescent Mesoporous Silica Nanoparticles Containing 8-Hydroxyquinolinate Zinc Complexes显示文摘Fluorescent mesoporous silica nanoparticles functionalized with carboxyl group(Znq-CMSCOOH) were successfully synthesized by in situ formation route of 8-hydroxyquinolinate zinc complexes in channels of mesoporous silica nanoparticles and post-grafting of carboxyl group on the surface. Moreover,the particle size and structural properties of Znq-CMS-COOH were characterized by transmission electron microscopy(TEM),field emission scanning electron microscopy(FE-SEM),dynamic light scattering(DLS),Fourier transform infrared spectroscopy(FT-IR),UV-vis spectrometer, fluorescence spectrometer and nitrogen adsorption-desorption measurements. The obtained results suggest that the Znq-CMS-COOH presents the uniform spherical shape with the mean diameter of about 85 nm and the obvious wormhole arrangement mesoporous. In addition, the Znq-CMS-COOH possesses green fluorescence with the emission peaks at 495 nm. So the Znq-CMS-COOH, which is beneficial to further modification and tracing, might be a great potential carrier for applying in drug delivery system in the future. | 王晚霞 WANG Youyun WANG Yu ZHU Hongda SUN Honghao 刘明星 | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，4： | 1 |
| 6 | Synthesis of Pt-SnOx/TS-1@SBA-16 Composites and Their High Catalytic Performance for Propane Dehydrogenation显示文摘A novel composite material of TS-1@SBA-16 was synthesized by enwrapping TS-1 zeolite crystals with mesoporous SBA-16 silica. This composite was used as catalyst support for loading Pt-SnOx in the propane dehydr genation(PDH) reaction. Catalysts were characterized by means ofN2 adsorption-desorption, XRD, SEM, TEM, XPS, UV-Vis, and Raman spectroscopy. The effect of different contents of TS-1 on PDH was investigated, and the optimal amount of TS-1 was determined to be 10%. The catalyst with TS-1 content of 10% showed the highest PDH activity and the initial conversion of propane over it can achieve 54.5%, higher than those over TS-1 or SB A-16-supported ones. The superior catalytic performance of Pt-SnOx/TS-1 @SBA-16 is related to the synergistic effect of the excellent mass transfer performance through the hierarchical porous structure, suitable acid acidity and electronic effect of Ti species. | LI Hongda ZHAO Zhen LI Jiacheng LI Jianmei ZHAO Linlin SUN Jiachen FAN Xiaoqiang | 2019 | Chemical Research in Chinese Universities2019，35，5： | 1 |
| 7 | The variation of the Kuroshio during 1986-1988显示文摘On the basis of the analysis of the data obtained from five cruises of the R/V Xiangyanghong 09 and the data from Japan, it is shown that a large meander of the Kuroshio appeared again during 1986-1988. The processes of formation , maturity and decline of this large meander are discussed in this study. The variation of the volume transport at Section Kb (PN) in the East China Sea is related to the large meander of the Kuroshio in the area south of Japan. By using maximum entropy spectrum analysis,the volume transport of the Kuroshio and the swing of its axis are analysed and their major periods are obained. | Sun Xiangping, Wang Yuanpei, Yuan Qike and Xu Hongda First Institute of Oceanography, State Oceanic Administration, Qingdao, ChinaNorth Sea Branch of State Oceanic Administration, Qingdao, China | 1991 | Acta Oceanologica Sinica1991，10，3： | 0 |
| 8 | Analysis of optical coupling behavior in twodimensional implant-defined coherently coupled vertical-cavity surface-emitting laser arrays显示文摘Optical coupling behavior and associated effects in two-dimensional implant-defined coherently coupled verticalcavity surface-emitting laser(VCSEL) arrays are studied via both experiments and theoretical calculations.Experiments show that optical coupling between array elements can enhance the array's output power.Additionally, optical coupling via leaky optical fields can provide extra optical gain for the array elements, which can then reduce the thresholds of these elements. Elements can even be pumped without current injection to emit light by receiving a strong leaky optical field from other array elements. Optical coupling can also cause unusual phenomena: the central elements in large-area coherently coupled VCSEL arrays that lase prior to the outer elements when the arrays are biased, or the average injection current required for each element to lase, which is much lower than the threshold for a single VCSEL.

| 10 | Tumor-targeted self-assembled micelles reducing PD-L1 expression combined with ICIs to enhance chemo-immunotherapy of TNBC显示文摘Immune checkpoint inhibitors(ICIs)therapy targeting programmed cell death ligand 1(PD-L1)and programmed death protein 1(PD-1)had exhibited significant clinical benefits for cancer treatment such as triple negative breast cancer(TNBC).However,the relatively low anti-tumor immune response rate and ICIs drug resistance highlight the necessity of developing ICIs combination therapy strategies to improve the anti-tumor effect of immunotherapy.Herein,the immunomodulator epigallocatechin gallate palmitate(PEGCG)and the immunoadjuvant metformin(MET)self-assembled into tumor-targeted micelles via hydrogen bond and electrostatic interaction,which encapsulated the therapeutic agents doxorubicin(DOX)-loaded PEGCG-MET micelles(PMD)and combined with ICIs(anti-PD-1 antibody)as therapeutic strategy to reduce the endogenous expression of PD-L1 and improve the tumor immunosuppressive microenvironment.The results presented that PMD integrated chemotherapy and immunotherapy to enhance antitumor efficacy in vitro and in vivo,compared with DOX or anti-PD-1 antibody for the therapy of TNBC.PMD micelles might be a potential candidate,which could remedy the shortcomings of antibody-based ICIs and provide synergistic effect to enhance the antitumor effects of ICIs in tumor therapy. | Hongda Zhu Kai Ma Rui Ruan Chaobo Yang Aqin Yan Jing Li Qi Yu Hongmei Sun Mingxing Liu Hongmei Zheng Jing Gao Xiaofang Guan Zhu Dai Yao Sun | 2024 | Chinese Chemical Letters2024，35，2： | 0 |
| 11 | Genetic Differentiation and Conservation of 14 Surviving Individuals of Euryodendron excelsum Endemic to China显示文摘Random amplification polymorphicDNA(RAPD)markers were used to assess the genetic variations and the evolutionary relationships among all 14 individuals of a critically endangered Euryodendron excelsum(Theaceae)population distributed in Ba Jia Zhen,Yangchun,Guangdong,China.Twenty-three random primers detected 156 sites,out of which 95(60.26%)were polymorphic loci.The number of the observed alleles was 1.6090,and the number of the effective alleles was 1.3471.Nei’s gene diversity was 0.1993,and Shannon index was 0.1534.A relatively high level of genetic variation was identified in E.excelsum.An unweighted pair group method with arithmetic mean(UPGMA)tree established from Jaccard similarity coefficients suggested that 14 individuals were clustered into two subgroups and that the No.2 plant was genetically distant from the rest of the individuals.The UPGMA clustering was also supported by a principle components analysis of RAPD phenotypic data.The management and conservation strategy of E.excelsum was proposed based on our results. | Wang Ting Su Yingjuan Ye Huagu Ouyang Puyue Jiang Yu Sun Yufei Chen Guopei Deng Feng Zhang Hongda | 2006 | Frontiers in Biology2006，1，1： | 0 |
