Enhanced performance of solid-state Li–O_2 battery using a novel integrated architecture of gel polymer electrolyte and nanoarray cathode

引用

Rare Metals 2018年第6期37卷 527-535页

作者： Liang Xiao Er-Wei Li jing-Yu Yi Wen Meng Bo-Hua Deng jin-ping liu School of Chemistry Chemical Engineering and Life Sciences Wuhan University of Technology State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology

The present work proposes a novel strategy to fabricate an integrated architecture of gel polymer electrolyte （GPE）-nanoarray cathode for lithium-O2 batteries （LOBs）. As a proof-of-concept experiment, the photo-initiated in situ polymerization of GPE was carried out via incorporating the precursor solution in advance into a self- standing binder-free oxygen electrode of Co3O4 nanosheets array grown on carbon cloth （Co3O4@CC）, forming an integrated GPE-Co3O4@CC architecture. The performance of the solid-state LOBs using the GPE-Co3O4@CC assembly is greatly enhanced compared to the counterparts with a traditional cell structure, in which GPE was sandwiched by a lithium metal and a cathode. The enhanced performance is ascribed to the combination of the in situ polymerization of GPE and the versatile structure of nanoarray electrode, which results in abundant interfacial contacts between GPE and electrode. This work presents an alternative way to develop high-performance solid-state LOBs by combining the advantages of both gel polymer electrolytes and nanoarray electrodes.

Current Medical Science 2018年第4期38卷 691-696页

作者： Peng BAI Yi-xuan WANG Si CHEN jin-ping liu Nian-guo DONG Jun-wei liu Department of Cardiovascular Surgery Union Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan 430022 China

This study aims to evaluate the clinical outcomes of endoscopic vein harvesting （EVH） for coronary artery bypass grafting （CABG） in obese patients. Totally, 153 obese patients who underwent EVH （n=81） or standard bridging technique （SBT, n=72） in CABG surgery from May 2012 to October 2014 in our hospital were enrolled in this retrospective non-randomized controlled study. The general situation of operation, postoperative complications and short medium-term outcomes were analyzed. The baseline characteristics were similar between these two groups （P〉0.05）. There were no statistical differences in total operation time （226±28 min vs. 224±30 min, P〉0.05）, number of damaged vessels （0.12±0.05 vs. 0.16±0.06, P〉0.05） and short medium-term outcomes including revascularization rate （1.25% vs. 2.78%, P〉0.05）, vessel dysfunction rate （11.25% vs. 11.11%, P〉0.05） and mortality （0.00% vs. 0.00%, P〉0.05）. Use of EVH was associated with significant reduction of total harvesting time （41±6 min vs. 63±11 min, P〈0.05）, incision length （4.4±1.1 cm vs. 18.2±4.5 cm, P〈0.05） and postoperative lower extremity complications （P〈0.05）. EVH can reduce the risk of wound complications, whereas does not influence short- and medium-term outcomes in obese patients. It can be considered a reliable procedure of harvesting vessel conduits for obese patients undergoing CABG.

Interactive image segmentation with a regression based ensemble learning paradigm

引用

Frontiers of Information Technology & Electronic Engineering 2017年第7期18卷 1002-1020页

作者： jin ZHANG Zhao-hui TANG Wei-hua GUI Qing CHEN jin-ping liu School of Information Science and Engineering Central South University Changsha 410083 China College of Computer and Communication Hunan University of Technology Zhuzhou 412007 China College of Mathematics and Computer Science Hunan Normal University Changsha 410083 China

To achieve fine segmentation of complex natural images, people often resort to an interactive segmentation paradigm, since fully automatic methods often fail to obtain a result consistent with the ground truth. However, when the foreground and background share some similar areas in color, the fine segmentation result of conventional interactive methods usually relies on the increase o f manual labels. This paper presents a novel interactive image segmentation method via a regression-based ensemble model with semi-supervised learning. The task is formulated as a non-linear problem integrating two complementary spline regressors and strengthening the robustness of each regressor via semi-supervised learning. First, two spline regressors with a complementary nature are constructed based on multivariate adaptive regression splines （MARS） and smooth thin plate spline regression （TPSR）. Then, a regressor boosting method based on a clustering hypothesis and semi-supervised learning is proposed to assist the training of MARS and TPSR by using the region segmentation information contained in unlabeled pixels. Next, a support vector regression （SVR） based decision fusion model is adopted to integrate the results of MARS and TPSR. Finally, the GraphCut is introduced and combined with the SVR ensemble results to achieve image segmentation. Extensive experimental results on benchmark datasets of BSDS500 and Pascal VOC have demonstrated the effectiveness of our method, and the com- parison with experiment results has validated that the proposed method is comparable with the state-of-the-art methods for in- teractive natural image segmentation.

Chinese Medical Journal 2015年第17期128卷 2290-2294页

作者： Fei Li Jie Cai Yong-Feng Sun jin-ping liu Nian-Guo Dong Department of Cardiovascular Surgery Union Hospital Tongji Medical College Huazhong University of Science and Technology Wuhan Hubei 430022 China

Background： Although heart transplantation （HTx） has become a standard therapy for end-stage heart diseases, experience with pediatric HTx is limited in China. In this article, we will try to provide the experience with indications, complications, perioperative management, immunosuppressive therapy, and survival for pediatric HTx based on our clinical work. Methods： This is a retrospective chart review of the pediatric patients undergoing HTx at Department of Cardiovascular Surgery of Union Hospital from September 2008 to December 2014. We summarized the indications, surgical variables, postoperative complications, and survival for these patients. Results： Nineteen pediatric patients presented for HTx at Union Hospital of Tongji Medical College, of whom 10 were male. The age at the time of transplantation ranged from 3 months to 18 years （median 15 years）. Patient weight ranged from 5.2 kg to 57.0 kg （median 38.0 kg）. Pretransplant diagnosis included cardiomyopathy （14 cases）, complex congenital heart disease （3 cases）, and tumor （2 cases）. All recipients received ABO-compatible donor hearts. Postoperative complications occurred in 12 patients, including cardiac dysfunction, arrhythmia, pulmonary infection, renal dysfunction, and rejection. Two of them experienced cardiac failure and required extracorporeal membrane oxygenation. The immunosuppression regimen was comprised ofprednisone, a calcineurin inhibitor, and mycophenolate. All patients recovered with New York Heart Association （NYHA） Class I-II cardiac function and were discharged. Only one patient suffered sudden death 19 months after transplantation. Conclusion： Orthotopic HTx is a promising therapeutic option with satisfying survival for the pediatric population in China with end-stage heart disease.

Chinese Medical Journal 2016年第6期129卷 702-708页

Background： Antegrade selective cerebral perfusion （ASCP） is regarded to perform cerebral protection during the thoracic aorta surgery as an adjunctive technique to deep hypothermic circulatory arrest （DHCA）. However, brain metabolism profile after ASCP has not been systematically investigated by metabolomics technology. Methods： To clarify the metabolomics profiling of ASCP, 12 New Zealand white rabbits were randomly assigned into 60 min DHCA with （DHCA＋ASCP [DA] group, n = 6） and without （ DHCA [D] group, n = 6） ASCP according to the random number table. ASCP was conducted by cannulation on the right subclavian artery and cross-clamping of the innominate artery. Rabbits were sacrificed 60 min after weaning off cardiopulmonary bypass. The metabolic features of the cerebral cortex were analyzed by a nontargeted metabolic profiling strategy based on gas chromatography-mass spectrometry. Variable importance projection values exceeding 1.0 were selected as potentially changed metabolites, and then Student＇s t-test was applied to test for statistical significance between the two groups. Results： Metabolic profiling of brain was distinctive significantly between the two groups （Q2y = 0.88 for partial least squares-DA model）. In comparing to group D, 62 definable metabolites were varied significantly after ASCP, which were mainly related to amino acid metabolism, carbohydrate metabolism, and lipid metabolism. Kyoto Encyclopedia of Genes and Genomes analysis revealed that metabolic pathways after DHCA with ASCP were mainly involved in the activated glycolytic pathway, subdued anaerobic metabolism, and oxidative stress. In addition, L-kynurenine （P = 0.0019）, 5-methoxyindole-3-acetic acid （P = 0.0499）, and 5-hydroxyindole-3-acetic acid （P = 0.0495） in tryptophan metabolism pathways were decreased, and citrulline （P - 0.0158） in urea cycle was increased in group DA comparing to group D. Conclusions： The present study applied metabolomics analysis to identify the cerebral met

INTRODUCTION ＂End-stage heart disease＂ commonly refers to an irreversible stage of cardiac decompensation caused by a variety of pathologies that cannot be treated using conventional drugs or traditional surgical treatments. The life expectancy of patients with end-stage heart disease ranges from 〈6 months to 1 year. Therapeutic strategies for end-stage heart disease patients are primarily based on three approaches： Internal medicine therapy, surgical therapy （heart transplantation）, and multiple organ protection therapy via the core method of mechanical circulation assistance. Among these approaches, heart transplantation has become recognized as the most efl＇ective treatment.
