| 1 | Correlation between lower gastrointestinal tract symptoms and quality of life in patients with stable chronic obstructive pulmonary disease显示文摘OBJECTIVE:To explore correlations between the symptoms of constipation and abdominal distention and severity of chronic obstructive pulmonary disease(COPD)in patients with stable disease.METHODS:We studied 191 patients with stable COPD(according to defined criteria)in this cross-sectional study from four three-level class A Chinese medicine hospitals in China.We built an Epidata 3.0 database and performed statistical analysis with SPSS,version 17.0.We analyzed correlations between the frequency of lower gastrointestinal tract symptoms(constipation and abdominal distention)and scores for major pulmonary symptoms(cough,sputum and wheezing)based on the St.George's Respiratory Questionnaire(SGRQ),6-minute walking distance(6MWD)and frequency of acute exacerbations of COPD(AECOPD).RESULTS:In addition to their pulmonary symptoms,39.79%and 40.31%of study patients withstable COPD reported constipation and abdominal distention,respectively.Scores for major pulmonary symptoms(cough,sputum and wheezing),AECOPD and SGRQ values in patients with constipation and abdominal distention were significantly greater,and the 6MWD markedly shorter,than in those without them.According to Pearson's correlation analysis,there were strong correlations between these lower gastrointestinal tract symptoms and scores for pulmonary symptoms,SGRQ,6MWD and AECOPD.CONCLUSION:Lower gastrointestinal tract symptoms such as constipation and abdominal distention can adversely affect pulmonary symptoms,frequency of acute exacerbations and quality of life in patients with stable COPD. | Yan Sun Fengjie Zheng Yuhang Li Ruohan Wu Yuchao Liu Miao Liu Jinchao Zhang Kuo Gao | 2013 | Journal of Traditional Chinese Medicine2013，33，5： | 10 |
| 2 | Sugarcane bagasse dietary fiber as an adjuvant therapy for stable chronic obstructive pulmonary disease:a four-center,randomized,double-blind,placebo-controlled study显示文摘OBJECTIVE:To evaluate the efficacy and safety of sugarcane bagasse dietary fiber as an adjuvant therapy for improving quality of life in patients with stable chronic obstructive pulmonary disease(COPD).METHODS:This was a multicenter,randomized,double-blind,placebo-controlled trial.A total of196 participants were randomized into a trial group(treated with 6 g/day sugarcane bagasse plus conventional treatment,n = 98) and a control group(treated with placebo plus conventional treatment,n = 98).All efficacy analyses were performed according to the intention-to-treat(ITT) principle.A per-protocol analysis set(PPS) was used to analyze the cases that completed the clinical trial with good compliance.The trial period was 30 days,with a 6-month follow-up.Pre-and post-treatmentpulmonary symptom scores(cough,sputum,wheezing,and dyspnea) were recorded for both groups.The St.George's Respiratory Questionnaire(SGRQ) and the modified Medical Research Council(m MRC) dyspnea scale were assessed before treatment and at the end of the 6-month follow-up.RESULTS:The ITT population was 178 and the PPS population was 166.Post-treatment pulmonary clinical symptoms and severity of dyspnea(m MRC and SGRQ evaluation) were significantly improved in both the trial group and the control group(ITT and PPS:P < 0.05).However,there was no statistical difference between the two groups in post-treatment pulmonary symptoms and m MRC.There was a greater reduction in the SGRQ subscales of activity,effect and total score in the trial group compared with the control group(ITT and PPS:P < 0.01).There was no statistical difference in pre-and post-treatment safety variables in either group.CONCLUSION:Sugarcane bagasse combined with conventional treatment improved quality of life in patients with stable COPD.Sugarcane bagasse appears to be a safe herbal medicine with potential for treating patients with stable COPD when taken orally as an adjuvant therapy. | Liu Miao Zheng Fengjie Ni Lei Sun Yan Wu Ruohan Zhang Tianyu Zhang Jinchao Zhong Xianggen Li Yuhang | 2016 | Journal of Traditional Chinese Medicine2016，36，4： | 2 |
| 3 | Tunable Ru-Ru2P heterostructures with charge redistribution for efficient pH-universal hydrogen evolution显示文摘Designing synergistic heterogeneous catalytic interfaces is the key to developing highly compatible pH-universal electrocatalysts for complex chemical environments.Our theoretical calculation results demonstrate that the Ru-Ru2P heterointerface can not only promote the redistribution of charges,but also reduce the d-band center,and then enhances the adsorption capacity of the key intermediate.However,in situ and facile synthesis of Ru-Ru2P heterostructures is severely limited by thermodynamic obstacles.Herein,we propose a molten salt-assisted catalytic synthesis scheme,and successfully build a series of homologous metallic Ru-Ru2P heterostructure catalysts with different molar ratios of Ru to P under atmospheric pressure and low-temperature(400C).The resultant Ru-Ru2P with rich heterostructures show the Pt-like HER performance in different pH media.Particularly,it is prominent under alkaline conditions(18 mV@10 mA cm^(2)),which outperforms the Pt catalyst(37 mV@10 mA cm^(2)).Furthermore,Ru-Ru2P heterostructures also show certain potential in the electrolysis of seawater to produce hydrogen.This work represents a significant supplement of high-efficiency pH-universal HER catalysts,and provides a new light on interface engineering in energy technology fields and beyond. | Ding Chen Ruohan Yu Ruihu Lu Zonghua Pu Pengyan Wang Jiawei Zhu Pengxia Ji Dulan Wu Jinsong Wu Yan Zhao Zongkui Kou Jun Yu Shichun Mu | 2022 | InfoMat2022，4，5： | 2 |
| 4 | Unraveling the reaction mechanisms of electrode materials for sodiumion and potassium‐ion batteries by in situ transmission electron microscopy显示文摘Sodium ion batteries(SIBs)and potassium ion batteries(PIBs)have caught numerous attention due to the low cost and abundant availability of sodium and potassium.However,their power density,cycling stability and safety need further improvement for practical applications.Investigations on the reaction mechanisms and structural degradation when cycling are of great importance.In situ transmission electron microscopy(TEM)is one of the most significant techniques to understand and monitor electrochemical processes at an atomic scale with real-time imaging.In this review,the current progress in unraveling reaction mechanisms of electrode materials for SIBs and PIBs via in situ TEM is summarized.First,the importance of in situ TEM is highlighted.Then,based on the three types of electrochemical reaction,i.e.,intercalation reac-tion,conversion reaction and alloying reaction,the structural evolution and reaction kinetics at atomic resolution,and their relation to the electrochemical performance of electrode materials are reviewed and described in detail.Fi-nally,future directions of in situ TEM for SIBs and PIBs are proposed.Therefore,the in‐depth understanding revealed by in situ TEM will give an instructive guide in rational design of electrode materials for high performance electrode materials of SIBs and PIBs. | Hong Wang Fang Liu Ruohan Yu Jinsong Wu | 2022 | Interdisciplinary Materials2022，1，2： | 2 |

| 7 | Revitalizing Human-Robot Interaction: Phygital Twin Driven Robot Avatar for China-Sweden Teleoperation显示文摘1 Introduction Digital Twin(DT)is built and maintained in the digital rather physical realm[1,2].Dynamic DT mirrors the exact state of the physical system by means of multidimensional models describing the behavior of physical entity,and sensors providing the real-time coupling to models[3].Te outbreak of COVID-19 pandemic results in speeding up the virtualization and digitization of the physical entity with the support from DT.Nevertheless,quarantine and division led by COVID-19 pandemic make human beings’eyes for the physical interaction become more eager.Te physical world and the digital world are becoming interwoven,which indicates a new opportunity towards phygital twin.As is so often the question:how can I get closer to my distant companion?How can I extend my service or emotional concern to facilitate interaction in spite of space obstruction?Tese questions deserve thinking as a lesson learned from outbreak of COVID-19 pandemic. | Huiying Zhou Honghao Lv Ruohan Wang Haiteng Wu Geng Yang | 2023 | Chinese Journal of Mechanical Engineering2023，36，5： | 0 |
| 8 | Tuning Active Metal Atomic Spacing by Filling of Light Atoms and Resulting Reversed Hydrogen Adsorption-Distance Relationship for Efficient Catalysis显示文摘Precisely tuning the spacing of the active centers on the atomic scale is of great significance to improve the catalytic activity and deepen the understanding of the catalytic mechanism,but still remains a challenge.Here,we develop a strategy to dilute catalytically active metal interatomic spacing(d_(M-M))with light atoms and discover the unusual adsorption patterns.For example,by elevating the content of boron as interstitial atoms,the atomic spacing of osmium(d_(Os-Os))gradually increases from 2.73 to 2.96?.More importantly,we find that,with the increase in dOs-Os,the hydrogen adsorption-distance relationship is reversed via downshifting d-band states,which breaks the traditional cognition,thereby optimizing the H adsorption and H_2O dissociation on the electrode surface during the catalytic process;this finally leads to a nearly linear increase in hydrogen evolution reaction activity.Namely,the maximum dOs-Os of 2.96?presents the optimal HER activity(8 mV@10 mA cm^(-2))in alkaline media as well as suppressed O adsorption and thus promoted stability.It is believed that this novel atomic-level distance modulation strategy of catalytic sites and the reversed hydrogen adsorption-distance relationship can shew new insights for optimal design of highly efficient catalysts. | Ding Chen Ruihu Lu Ruohan Yu Hongyu Zhao Dulan Wu Youtao Yao Kesong Yu Jiawei Zhu Pengxia Ji Zonghua Pu Zongkui Kou Jun Yu Jinsong Wu Shichun Mu | 2023 | Nano-Micro Letters2023，15，10： | 0 |
| 9 | Photoexcitation-induced passivation of SnO_(2) thin film for efficient perovskite solar cells显示文摘A high-quality tin oxide electron transport layer(ETL)is a key common factor to achieve high-performance perovskite solar cells(PSCs).However,the conventional annealing technique to prepare high-quality ETLs by continuous heating under near-equilibrium conditions requires high temperatures and a long fabrication time.Alternatively,we present a non-equilibrium,photoexcitation-induced passivation technique that uses multiple ultrashort laser pulses.The ultrafast photoexcitation and following electron–electron and electron–phonon scattering processes induce ultrafast annealing to efficiently passivate surface and bulk defects,and improve the crystallinity of SnO_(2),resulting in suppressing the carrier recombination and facilitating the charge transport between the ETL and perovskite interface.By rapidly scanning the laser beam,the annealing time is reduced to several minutes,which is much more efficient compared with conventional thermal annealing.To demonstrate the university and scalability of this technique,typical antisolvent and antisolvent-free processed hybrid organic–inorganic metal halide PSCs have been fabricated and achieved the power conversion efficiency(PCE)of 24.14%and 22.75%respectively,and a 12-square-centimeter module antisolvent-free processed perovskite solar module achieves a PCE of 20.26%,with significantly enhanced performance both in PCE and stability.This study establishes a new approach towards the commercialization of efficient low-temperature manufacturing of PSCs. | Nianyao Chai Xiangyu Chen Zhongle Zeng Ruohan Yu Yunfan Yue Bo Mai Jinsong Wu Liqiang Mai Yi-Bing Cheng Xuewen Wang | 2023 | National Science Review2023，10，11： | 0 |
| 10 | ZIF-Mediated Anchoring of Co species on N-doped Carbon Nanorods as an Efficient Cathode Catalyst for Zn-Air Batteries显示文摘Developing efficient oxygen reduction reaction(ORR)catalyst is essential for the practical application of Zn-air batteries(ZABs).In this contribution,we develop a novel zeolitic imidazolate framework(ZIF)-mediated strategy to anchor Co species on N-doped carbon nanorods for efficient ORR.Featuring ultrahigh N-doping(10.29 at.%),monodisperse Co nanocrystal decoration,and well-dispersed Co-N_(x)functionalization,the obtained Co-decorated N-doped carbon nanorods(Co@NCNR)exhibit a decent ORR performance comparable to commercial Pt/C in alkaline media.Aqueous ZABs have been assembled using Co@NCNR as the cathode catalyst.The assembled ZABs manifest high initial open-circuit voltage as well as high energy density.In addition,the Co@NCNR also demonstrates ideal ORR performance in quasi-solid-state ZABs. | Qiang Yu Jianshuai Lv Jiantao Li Ruohan Yu Jinsong Wu Shibo Xi Xinyuan Li Nuo Xu Liang Zhou Liqiang Ma | 2023 | Energy & Environmental Materials2023，6，3： | 0 |
| 11 | Reservoir Characteristics and Controlling Factors of Silurian Lower Kepingtage Formation in Tahe Area, Tarim Basin, NW China显示文摘With the breakthrough of exploration in Well TP16-1, the lower Kepingtage Formation becomes a key target for petroleum exploration of deep clastic reservoir in Tahe area. In this paper we focused on the research of the reservoir characteristics and its controlling factors in two sub-member formations(S_1k_1~1 and S_1k_1~3). Based on X-ray diffraction, conventional physical properties data(porosity and permeability) and reservoir storage space data(casting thin section and scanning electron microscope), we determined that the S_1k_1 Formation belongs to extra-low porosity and permeability reservoir, although the upper S_1k_1~3 Formation shows relative better physical characteristic than the lower S_1k_1~1 Formation. The development of storage space in the study area is controlled by sedimentary microfacies, diagenesis process. Reservoirs in S_1k_1 Formation are mainly located in channel(S_1k_1~1 sandstones) and sand flat(S_1k_1~3 sandstones). The sand flat sediments with a more coarse grain size compared with the channel. In diagenesis, compaction is the major controlling factor for reducing the porosity, followed by cementation. Dissolution of diagenesis is the major controlling factor in enhancing the reservoir porosities. Compared with channel(S_1k_1~1) sandstones, sand flat sandstones(S_1k_1~3) have better reservoir quality for its weaker compaction, cementation and stronger dissolution. On the basis of sedimentary characteristics(grain size and subfacies), physical property(porosity and permeability) and reservoir storage space, we divide the S_1k_1 reservoir into three categories(I, II and III). Type I reservoir is high quality reservoir. It is mainly distributed in the south area of S_1k_1~1 and S_1k_1~3 reservoir. Type II is moderate reservoir. It is located in the middle of S_1k_1~1 reservoir and in the north of S_1k_1~3 reservoir. Type III is the poor reservoir. It is only located in the north of S_1k_1~1 reservoir. | Ruohan Liu Zaixing Jiang Ming Wang Weili Yang Jingxiang Guo Minghao Wu Yi Gao Shanyazi Wei Zhihong Nie Hong He | 2017 | Journal of Earth Science2017，28，6： | 0 |
