| 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 | High performance octahedral PtNi/C catalysts investigated from rotating disk electrode to membrane electrode assembly显示文摘Octahedral PtNi/C catalysts have demonstrated superior catalytic performance in oxyge n reduction reacti on (ORR) over commercial Pt/C with rotating disk electrode (RDE). However, it is not trivial to translate such promising results to real-world membrane-electrode assembly (MEA). In this work, we have synthesized octahedral PtNi/C catalysts using poly(diallyldimethylammonium chloride)(PDDA) as a capping age nt and in vestigated their performance from RDE to MEA. In RDE, mass activity and specific activity of the optimized octahedral PtNi/C catalyst for oxygen reduction reaction (ORR) are nearly 19 and 28 times high of the state-of-the-art commercial Pt/C, respectively. At MEA level, the octahedral PtNi/C catalyst exhibits excelle nt power generation performa nee and durability paired with commercial Pt/C ano de. Its cell voltage at 1,000mA·cm^-2 reaches 0.712 V, and maximum power density is 881.6 mW·cm^-2 and its performance attenuation is also less, around 11.8% and 7% under galvanostatic condition of 1,000 mA·cm^-2 for 100 h. Such results are investiaged by thermodynamic analysis and fundametal performance modeling, which indicate the single cell performance can be further improved by reducing the size of PtNi/C catalyst agglomerates. Such encouraging results have demonstrated the feasibility to convey the superior performance of octahedral PtNi/C from RDE to MEA. | Bing Li Jue Wang Xin Gao Congwei Qin Daijun Yang Hong Lv Qiangfeng Xiao Cunman Zhang | 2019 | Nano Research2019，12，2： | 3 |
| 3 | The Controllable Design of Catalyst Inks to Enhance PEMFC Performance:A Review显示文摘Typical catalyst inks in proton exchange membrane fuel cells(PEMFCs)are composed of a catalyst,its support,an ionomer and a solvent and are used with solution processing approaches to manufacture conventional catalyst layers(CLs).Because of this,catalyst ink formulation and deposition processes are closely related to CL structure and performance.However,catalyst inks with ideal rheology and optimized electrochemical performances remain lacking in the large-scale application of PEMFCs.To address this,this review will summarize current progress in the formulation,characterization,modeling and deposition of catalyst inks.In addition,this review will highlight recent advancements in catalyst ink materials and discuss corresponding complex interactions.This review will also present various catalyst ink dispersion methods with insights into their stability and introduce the application of small-angle scattering and cryogenic transmission electron microscopy(cryo-TEM)technologies in the characterization of catalyst ink microstructures.Finally,recent studies in the kinetic modeling and deposition of catalyst inks will be analyzed. | Yuqing Guo Fengwen Pan Wenmiao Chen Zhiqiang Ding Daijun Yang Bing Li Pingwen Ming Cunman Zhang | 2021 | Electrochemical Energy Reviews2021，4，1： | 2 |

| 14 | Accelerated Test of Silicone Rubbers Exposing to PEMFC environment显示文摘The durability of sealing material is one of the major challenges to the overall lifetime of proton exchange membrane fuel cell(PEMFC).In order to study the failure mode and aging mechanism of fuel cell seals,this paper focuses on the most widely used commercial silicone rubber,and an ex-situ accelerated aging method was employed by simulating the circumstance of PEMFC,including higher temperature and clamping force,lower p H value and F-with higher concentration.The main factors that affect the performance of the seal were obtained through the test of their morphologies and mechanical properties.The failure mode of the aging mechanism of the rubbers were analyzed through scanning electron microscopy(SEM),energy dispersive spectrometer(EDS),attenuated-total-reflection infrared spectroscopy(ATR-IR),mass loss,compression set(CS),etc.It was found that temperature played an important role in the deterioration of seal performance,and the change of the parameters of the compression set with time conformed the dynamic empirical formula,which provides the experimental basis for the lifetime prediction of the seals. | Daijun Yang Jingwen Ma Qing Zhang Bing Li Pingwen Ming Cunman Zhang | 2020 | Progress in Natural Science:Materials International2020，30，6： | 0 |
| 15 | Huge and ruptured amoebic liver abscess diagnosed by mNGS:A case report显示文摘Background Amoebic liver abscess(ALA)is caused by the protozoan parasite,Entamoeba histolytica,which is the most common extraintestinal presentation of infection with the protozoan.[1]Areas of high incidence of infection worldwide include India,Africa,Mexico,and parts of Central and South America.Although the prognosis of simple abscess is favorable,complex and large abscesses may rupture and be associated with high mortality.[2]The diagnosis of ALA is made through a combination of characteristic findings on imaging and serologic testing(antigen or antibody testing). | Weiqin Wang Daijun Song Xin Li Hui Xie | 2022 | Journal of Intensive Medicine2022，2，2： | 0 |

| 18 | Modifying Carbon Supports of Catalyst for the Oxygen Reduction Reaction in Vehicle PEMFCs显示文摘For current carbon-supported Pt catalysts in vehicle proton exchange membrane fuel cells(PEMFCs),the insufficient stability and durability of carbon supports are severe limitations under operating conditions.This paper adopts the accelerated stress test(AST)method to study the carbon corrosion of catalysts,which is significant to efficiently select the catalysts supports in fuel cells.Graphitized carbon blacks with various surface properties are heated under different conditions,followed by evaluation of their antioxidation capacity with the AST.It is shown that optimally graphitized carbon blacks demonstrate superior stability,retaining a constant quinone/hydroquinone(QH)transition peak potential for over 70,000 AST cycles.A Pt catalyst supported on the selected graphitized carbon exhibits excellent durability at both the rotating disk electrode(RDE)and membrane electrode assembly(MEA)levels.The final specific mass activity(MA)of the optimum catalyst is 47.87 mA/mgPt,which is 2.06 times that of commercial Pt/C(23.31 mA/mgPt)in the RDE tests.The final maximum power density of the optimum catalyst is 525.68 mW/cm^(2),which is 305.52 mW/cm^(2)higher than that of commercial Pt/C after undergoing the AST during the MEA measurements.These results prove that the rational surface features of carbon supports play a vital role in improving the overall fuel cell performance by realizing uniform dispersion of Pt nanoparticles,resisting corrosion,and reinforcing metal-support interactions. | Qiong Xue Daijun Yang Lei Jiang Bing Li Pingwen Ming | 2021 | Automotive Innovation2021，4，2： | 0 |
