| 1 | Prognostic nutritional index is an independent prognostic factor for gastric cancer patients with peritoneal dissemination显示文摘Objective: The predictive and prognostic role of prognostic nutritional index(PNI) in gastric cancer patients with peritoneal dissemination remains unclear. This study aims to explore the role of the PNI in predicting outcomes of gastric cancer patients with peritoneal dissemination.Methods: A total of 660 patients diagnosed with gastric adenocarcinoma with peritoneal metastasis between January 2000 and April 2014 at Sun Yat-sen University Cancer Center and the Sixth Affiliated Hospital of Sun Yatsen University were retrospectively analyzed. The clinicopathologic characteristics and clinical outcomes of patients with peritoneal dissemination were analyzed.Results: Compared with PNI-high group, PNI-low group was correlated with advanced age(P=0.036), worse performance status(P<0.001), higher frequency of ascites(P<0.001) and higher frequency of multisite distant metastasis(P<0.001). Kaplan-Meier survival curves showed that PNI-high group had a significantly longer median overall survival than PNI-low group(13.13 vs. 9.03 months, P<0.001). Multivariate survival analysis revealed that Borrmann type IV(P=0.014), presence of ascites(P=0.017) and lower PNI(P=0.041) were independent poor prognostic factors, and palliative surgery(P<0.001) and first-line chemotherapy(P<0.001) were good prognostic factors. For patients receiving palliative surgery, the postoperative morbidity rates in the PNI-low group and PNIhigh group were 9.1% and 9.9%, respectively(P=0.797). The postoperative mortality rate was not significantly different between PNI-low and PNI-high groups(2.3% vs. 0.9%, P=0.362).Conclusions: PNI is a useful and practical tool for evaluating the nutritional status of gastric cancer patients with peritoneal dissemination, and is an independent prognostic factor for these patients. | Runcong Nie Shuqiang Yuan Shi Chen Xiaojiang Chen Yongming Chen Baoyan Zhu Haibo Qiu Zhiwei Zhou Junsheng Peng Yingbo Chen | 2016 | Chinese Journal of Cancer Research2016，28，6： | 19 |
| 2 | Analysis and external validation of a nomogram to predict peritoneal dissemination in gastric cancer显示文摘Objective:Peritoneal dissemination is difficult to diagnose by conventional imaging technologies.We aimed to construct a nomogram to predict peritoneal dissemination in gastric cancer(GC)patients.Methods:We retrospectively analyzed 1,112 GC patients in Sun Yat-sen University Cancer Center between2001 and 2010 as the development set and 474 patients from The Sixth Affiliated Hospital,Sun Yat-sen University between 2010 and 2016 as the validation set.The clinicopathological variables associated with gastric cancer with peritoneal dissemination(GCPD)were analyzed.We used logistic regression analysis to identify independent risk factors for peritoneal dissemination.Then,we constructed a nomogram for the prediction of GCPD and defined its predictive value with a receiver operating characteristic(ROC)curve.External validation was performed to validate the applicability of the nomogram.Results:In total,250 patients were histologically identified as having peritoneal dissemination.Logistic regression analysis demonstrated that age,sex,tumor location,tumor size,signet-ring cell carcinoma(SRCC),T stage,N stage and Borrmann classification IV(Borrmann IV)were independent risk factors for peritoneal dissemination.We constructed a nomogram consisting of these eight factors to predict GCPD and found an optimistic predictive capability,with a C-index of 0.791,an area under the curve(AUC)of 0.791,and a 95%confidence interval(95%CI)of 0.762-0.820.The results found in the external validation set were also promising.Conclusions:We constructed a highly sensitive nomogram that can assist clinicians in the early diagnosis of GCPD and serve as a reference for optimizing clinical management strategies. | Xijie Chen Shi Chen Xinyou Wang Runcong Nie Dongwen Chen Jun Xiang Yijia Lin Yingbo Chen Junsheng Peng | 2020 | Chinese Journal of Cancer Research2020，32，2： | 6 |
| 3 | A nomogram to predict prognosis for gastric cancer with peritoneal dissemination显示文摘Objective: To identify independent prognostic factors to be included in a nomogram to predict the prognosis of gastric cancer patients with peritoneal dissemination.Methods: This is a retrospective study on 684 patients with a histological diagnosis of gastric cancer with peritoneal dissemination from the Sun Yat-sen University Cancer Center as the development set, and 62 gastric cancer patients from the Sixth Affiliated Hospital of Sun Yat-sen University as the validation group. Chi-square test and Cox regression analysis were used to compare the clinicopathological variables and the prognosis of gastric cancer patients with peritoneal dissemination. The Harrell's concordance index(C-index) and calibration curve were determined for comparisons of predictive ability of the nomogram.Results: Univariate and multivariate analyses showed that serum carcinoembryonic antigen(CEA) level(P=0.032), ascites grading(P=0.008), presence of extraperitoneal metastasis(P<0.001), seeding status(P=0.016) and performance status(P=0.009) were independent prognostic factors for gastric cancer patients with peritoneal dissemination in the development set. The nomogram model was constructed using these five factors. Internal validation showed that the C-index of the model was 0.641. For the external validation, the C-index of this model was 0.709.Conclusions: We developed and validated a nomogram to predict the prognosis for gastric cancer patients with peritoneal dissemination. This nomogram may play an important clinical role in guiding palliative therapy for these types of patients, although it may need more data for optimization. | Shi Chen Xijie Chen Runcong Nie Liying Ou Yang Aihong Liu Yuanfang Li Zhiwei Zhou Yingbo Chen Junsheng Peng | 2018 | Chinese Journal of Cancer Research2018，30，4： | 5 |
| 4 | MODIS observations of water color of the largest 10 lakes in China between 2000 and 2012显示文摘Forel-Ule(FU)index of water color is an important parameter in traditional water quality investigations.We retrieved the FU index of the largest 10 lakes in China during 2000-2012 from MODerate-resolution Imaging Spectroradiometer surface reflectance product(MOD09)images.Since FU index is an optical parameter,it can be derived from optical remote sensing data by direct formulas,which is invariant with region and season.Based on validation by in situ measured reflectance data,the FU index products are reliable,with average relative error of 7.7%.FU index can be used to roughly assess water clarity:the clearer a water body is,and the bluer it is in color,the smaller its FU index is.FU index can also be used to roughly classify trophic state into three classes:oligotrophic,mesotrophic,and eutrophic.We analyzed the spatial,interannual,and seasonal variations of the FU index and its implications for water clarity and trophic state,and the findings are mostly consistent with the results from related literature.All in all,it might be a feasible way to roughly assess inland water quality by FU index in large region and over long time period. | Junsheng Li Shenglei Wang Yanhong Wu Bing Zhang Xiaoling Chen Fangfang Zhang Qian Shen Dailiang Peng Liqiao Tian | 2016 | International Journal of Digital Earth2016，9，8： | 5 |

| 6 | Three-dimensionally Ordered Macroporous Phosphotungstic Acid/SiO2 for Efficient Catalytic Oxidative Desulfurization显示文摘Three-dimensionally ordered(3DOM) macroporous phosphotungstic acid/SiO_2(HPW/SiO_2) materials were prepared by using colloidal crystal as templates and applied for oxidative desulfurization(ODS) of the model fuel oil. The obtained HPW/SiO_2 materials were characterized through scanning electron microscopy, powder X-ray diffraction, N_2 sorption, and Fourier transform infrared spectroscopy. The results indicated that 3 DOM HPW/SiO_2 possessed hierarchical pore architectures which contained ordered macropores and disordered mesopores, with the Keggin type HPW embedded in the framework of pore structure. The removal rate of dibenzothiophene(DBT) could reach 100% under the optimum conditions, moreover. The performance was only slightly decreased for the regenerated catalyst after 7 cycles. | 杜岳 YANG Peng 雷家珩 ZHOU Shiyu LI Junsheng DU Xiaodi | 2018 | Journal of Wuhan University of Technology(Materials Science)2018，33，4： | 3 |
| 7 | Cobalt tungsten phosphide with tunable W-doping as highly efficient electrocatalysts for hydrogen evolution reaction显示文摘It has been of interest in seeking electrocatalysts that could exercise equally high-efficient and durable hydrogen evolution upon nonselective electrolytes in both acidic and alkaline environments. Herein, we report a facile strategy to fabricate cobalt tungsten phosphides (CoxW2−xP2/C) hollow polyhedrons with tunable composition based on metal-organic frameworks (MOFs) template method. By the deliberate control of W doping, the synthesized catalyst with the composition of Co0.9W1.1P2/C is found to be able to achieve a current density of 10 mA·cm^(−2) at overpotentials of 35 and 54 mV in acidic and alkaline media, respectively. This combined electrochemical property stands atop the state-of-the-art electrocatalyst counterparts. To unveil the peculiar behavior of the structure, density functional theory (DFT) calculation was implemented and reveals that the surface W-doping facilitates the optimization of hydrogen absorption free energy (ΔGH*) as well as the thermodynamic and kinetics barriers for water dissociation, which is coupled with the hollow structure of Co-W phosphides, leading to the prominent HER catalytic performance. | Bowei Zhang Chaojiang Li Jun Hu Dongdong Peng Kang Huang Junsheng Wu Zhong Chen Yizhong Huang | 2021 | Nano Research2021，14，11： | 1 |

| 9 | Stretchable organic electrochemical transistors via threedimensional porous elastic semiconducting films for artificial synaptic applications显示文摘Neuromorphic computing targets realizing biomimetic or intelligence systems capable of processing abundant tasks in parallel analogously to our brain,and organic electrochemical transistors(OECTs)that rely on the mixed ionic-electronic synergistic couple possess significant similarity to biological systems for implementing synaptic functions.However,the lack of reliable stretchability for synaptic OECTs,where mechanical deformation occurs,leads to consequent degradation of electrical performance.Herein,we demonstrate stretchable synaptic OECTs by adopting a three-dimensional poly(3-hexylthiophene)(P3HT)/styrene-ethylene-butylene-styrene(SEBS)blend porous elastic film for neuromorphic computing.Such architecture shows the full capability to emulate biological synaptic behaviors.Adjusting the accumulated layer numbers of porous film enables tunable OECT output and hysteresis,resulting in transition in plasticity.Especially,with a trilayer porous film,large-scale conductance and hysteresis are endorsed for efficient mimicking of memory-dependent synapse behavior.Benefitted from the interconnected three-dimensional porous structures,corresponding stretchable synaptic OECTs exhibit excellent mechanical robustness when stretched at a 30%strain,and maintain reliable electrical characteristics after 500 stretching cycles.Furthermore,near-ideal weight updates with near-zero nonlinearities,symmetricity in long-term potentiation(LTP)and depression,and applications for image simulation are validated.This work paves a universal design strategy toward highperformance stretchable neuromorphic computing architecture and could be extended to other flexible/stretchable electronics. | Yujie Peng Lin Gao Changjian Liu Jinyi Deng Miao Xie Libing Bai Gang Wang Yuhua Cheng Wei Huang Junsheng Yu | 2023 | Nano Research2023，16，7： | 1 |

| 14 | Flexible Au micro-array electrode with atomic-scale Au thin film for enhanced ethanol oxidation reaction显示文摘The catalysis of Au thin film could be improved by fabrication of array structures in large area.In this work,nanoimprint lithography has been developed tofabricate flexible Au micro-array(MA)electrodes with~100%coverage.Advanced electron microscopy characterisations have directly visualised the atomic-scale three-dimensional(3D)nanostructures with a maximum depth of 6 atomic layers.In-situ observation unveils the crystal growth in the form of twinning.High double layer capacitance brings about large number of active sites on the Au thin film and has a logarithmic relationship with mesh grade.Electrochemistry testing shows that the Au MAs perform much better ethanol oxidation reaction than the planar sample;MAs with higher mesh grade have a greater active site utilisation ratio(ASUR),which is important to build electrochemical double layer for efficient charge transfer.Further improvement on ASUR is expected for greater electrocatalytic performance and potential application in direct ethanol fuel cell. | Xun Cao Dongdong Peng Cao Wu Yongmin He Chaojiang Li Bowei Zhang Changcun Han Junsheng Wu Zheng Liu Yizhong Huang | 2021 | Nano Research2021，14，1： | 0 |
