| 1 | Multimorbidity patterns and association with mortality in 0.5 million Chinese adults显示文摘Background:Few studies have assessed the relationship between multimorbidity patterns and mortality risk in the Chinese population.We aimed to identify multimorbidity patterns and examined the associations of multimorbidity patterns and the number of chronic diseases with the risk of mortality among Chinese middle-aged and older adults.Methods:We used data from the China Kadoorie Biobank and included 512,723 participants aged 30 to 79 years.Multimorbidity was defined as the presence of two or more of the 15 chronic diseases collected by self-report or physical examination at baseline.Multimorbidity patterns were identified using hierarchical cluster analysis.Cox regression was used to estimate the associations of multimorbidity patterns and the number of chronic diseases with all-cause and cause-specific mortality.Results:Overall,15.8%of participants had multimorbidity.The prevalence of multimorbidity increased with age and was higher in urban than rural participants.Four multimorbidity patterns were identified,including cardiometabolic multimorbidity(diabetes,coronary heart disease,stroke,and hypertension),respiratory multimorbidity(tuberculosis,asthma,and chronic obstructive pulmonary disease),gastrointestinal and hepatorenal multimorbidity(gallstone disease,chronic kidney disease,cirrhosis,peptic ulcer,and cancer),and mental and arthritis multimorbidity(neurasthenia,psychiatric disorder,and rheumatoid arthritis).During a median of 10.8 years of follow-up,49,371 deaths occurred.Compared with participants without multimorbidity,cardiometabolic multimorbidity(hazard ratios[HR]=2.20,95%confidence intervals[CI]:2.14-2.26)and respiratory multimorbidity(HR=2.13,95%CI:1.97-2.31)demonstrated relatively higher risks of mortality,followed by gastrointestinal and hepatorenal multimorbidity(HR=1.33,95%CI:1.22-1.46).The mortality risk increased by 36%(HR=1.36,95%CI:1.35-1.37)with every additional disease.Conclusion:Cardiometabolic multimorbidity and respiratory multimorbidity posed the highest threat on mortality risk and deserved particular attention in Chinese adults. | Junning Fan Zhijia Sun Canqing Yu Yu Guo Pei Pei Ling Yang Yiping Chen Huaidong Du Dianjianyi Sun Yuanjie Pang Jun Zhang Simon Gilbert Daniel Avery Junshi Chen Zhengming Chen Jun Lyu Liming Li On Behalf of the China Kadoorie Biobank Collaborative Group | 2022 | Chinese Medical Journal2022，，6： | 17 |
| 2 | 中国成人糖尿病、血糖与结直肠癌发病率:针对50万人的前瞻性研究显示文摘背景糖尿病可致结直肠癌(CRC)的发病风险升高。糖尿病病程和非糖尿病患者的血糖与CRC发病风险之间的相关性仍不清楚。方法2004至2008年前瞻性中国Kadoofe Biobank研究从10个不同地区纳入了512 713名受试者。在10年随访期间,在基线无癌症史的510 136名受试者中共记录有3 024例新发CRC病例(1 745例结肠癌,1 716例直肠癌)。应用Cox回归分析对糖尿病(入组前诊断或筛查发现的)或无糖尿病病史者随机血糖(RPG)水平与CRC发病相关性的校正风险比(HR)进行估计。结果基线时,共有5.8%的受试者患有糖尿病。糖尿病患者发生CRC的校正HR为1.18(95%可信区间1.04~1.33),且发生结肠癌与直肠癌的风险相当[1.19(1.01~1.39)比1.14(0.96~1135)]。这些患者发生CRC的HR随糖尿病病程的延长而下降(趋势P值为0.03)。在入组前无糖尿病的受试者中,其RPG水平与CRC发病呈正相关,基线RPG每升高1 mmol/L其发生CRC的校正HR为1.04(1.02~1.05),且发生结肠癌与直肠癌的风险亦相当[1.03(1.01~1.05)比1.04(1.02~1.06)]。在男性中,糖尿病和RPG与CRC发病风险的相关性高于女性,但其差异无统计学意义(异质性检验的P值分别为0.3和0.2)。讨论在中国成年人中,未诊断糖尿病者其糖尿病和升高的血糖水平与CRC发病风险升高相关。 | Yuanjie Pang Christiana Kartsonak yu Guo Yiping Chen Ling Yang Zheng Bian Fiona Bragg Iona Y Millwood Leijia Shen Songgen Zhou Jiben Liu Junshi Chen Liming Li Michael V Holmes Zhengming Ghen 霍永丰(译) | 2019 | 英国医学杂志中文版2019，22，1： | 6 |
| 3 | A Teosinte-derived Allele of a MYB Transcription Repressor Confers Multiple Disease Resistance in Maize.显示文摘Natural alleles controlling multiple disease resistances (MDR) are valuable for crop breeding. However, only one MDR gene have been cloned in maize, and molecular mechanisms of MDR are not clear. By map-based cloning, we have cloned a teosinte-derived allele of a resistance gene, Mexicana lesion mimic 1 (ZmMM1), which has a lesion mimic phenotype and confers resistance to northern leaf blight (NLB), gray leaf spot (GLS) and southern corn rust (SCR). Strong MDR conferred by the teosinte allele is linked with the polymorphisms in the 3' untranslated region of the ZmMM1 gene that cause increased accumulation of ZmMM1 protein. ZmMM1 acts as a transcription repressor and negatively regulates transcription of specific target genes including ZmMM1-target gene 3 (ZmMT3), which functions as a negative regulator of plant immunity and associated cell death. The successful isolation of the ZmMM1 resistance gene will help not only in developing broad-spectrum and durable disease resistance but also in understanding the molecular mechanisms underlying MDR. | Hongze Wang Jiabao Hou Pei Ye Long Hu Junshi Huang Zhikang Dai Bao Zhang Sha Dai Jiamin Que Haoxuan Min Gengshen Chen Yanbo Wang Min Jiang Yan Liang Lin Li Xuecai Zhang Zhibing Lai | 2021 | Molecular Plant2021，14，11： | 4 |

| 5 | Associations of muscle mass,strength,and quality with all-cause mortality in China:a population-based cohort study显示文摘Background It remains unclear about the association of muscle mass,strength,and quality with death in the general Chinese population of diverse economical and geographical backgrounds.The present study aimed to comprehensively examine such associations across different regions in China.Methods Based on the China Kadoorie Biobank study,the present study included 23,290 participants who were aged 38 to 88 years and had no prevalent cardiovascular diseases or cancer.Muscle mass and grip strength were measured using calibrated instruments.Arm muscle quality was defined as the ratio of grip strength to arm muscle mass.Low muscle mass,grip strength,and arm muscle quality were defined as the sex-specific lowest quintiles of muscle mass index,grip strength,and arm muscle quality,respectively.Cox proportional hazards models yielded hazard ratios(HRs)and 95%confidence intervals(CIs)for risks of all-cause mortality in relation to muscle mass,strength,and quality.Results During a median follow-up of 3.98 years,739 participants died.The HR(95%CI)of all-cause mortality risk was 1.28(1.08–1.51)for low appendicular muscle mass index,1.38(1.16–1.62)for low total muscle mass index,1.68(1.41–2.00)for low grip strength,and 1.41(1.20–1.66)for low arm muscle quality in models adjusted for sociodemographic characteristics,lifestyle factors,and medical histories.Conclusion Low muscle mass,grip strength,and arm muscle quality are all associated with short-term increased risks of mortality,indicating the importance of maintaining normal muscle mass,strength,and quality for general Chinese adults. | Man Wu Yuxia Wei Jun Lv Yu Guo Pei Pei Jiachen Li Huaidong Du Ling Yang Yiping Chen Xiaohui Sun Hua Zhang Junshi Chen Zhengming Chen Canqing Yu Liming Li 无 | 2022 | Chinese Medical Journal2022，，11： | 2 |
| 6 | High‑Performance Flexible Microneedle Array as a Low‑Impedance Surface Biopotential Dry Electrode for Wearable Electrophysiological Recording and Polysomnography显示文摘Microneedle array(MNA)electrodes are an effective solution to achieve high-quality surface biopotential recording without the coordination of conductive gel and are thus very suitable for long-term wearable applications.Existing schemes are limited by flexibility,biosafety,and manufacturing costs,which create large barriers for wider applications.Here,we present a novel flexible MNA electrode that can simultaneously achieve flexibility of the substrate to fit a curved body surface,robustness of microneedles to penetrate the skin without fracture,and a simplified process to allow mass production.The compatibility with wearable wireless systems and the short preparation time of the electrodes significantly improves the comfort and convenience of electrophysiological recording.The normalized electrode–skin contact impedance reaches 0.98 kΩcm^(2)at 1 kHz and 1.50 kΩcm^(2)at 10 Hz,a record low value compared to previous reports and approximately 1/250 of the standard electrodes.The morphology,biosafety,and electrical/mechanical properties are fully characterized,and wearable recordings with a high signal-to-noise ratio and low motion artifacts are realized.The first reported clinical study of microneedle electrodes for surface electrophysiological monitoring was conducted in tens of healthy and sleep-disordered subjects with 44 nights of recording(over 8 h per night),providing substantial evidence that the electrodes can be leveraged to substitute for clinical standard electrodes. | Junshi Li Yundong Ma Dong Huang Zhongyan Wang Zhitong Zhang Yingjie Ren Mengyue Hong Yufeng Chen Tingyu Li Xiaoyi Shi Lu Cao Jiayan Zhang Bingli Jiao Junhua Liu Hongqiang Sun Zhihong Li | 2022 | Nano-Micro Letters2022，14，8： | 1 |
| 7 | Upgrading pyrolytic carbon-blacks (CBp) from end-of-life tires: Characteristics and modification methodologies显示文摘Over 1 billion end-of-life tires(ELTs)are generating annually,and 4 billion ELTs are currently abandoned in landfills and stockpiles worldwide,according to the statistics,leading to the environmental and health risks.To circumvent these issues,pyrolysis,as an attractive thermochemical process,has been addressed to tackle the ELTs'problem to reduce the risks as well as increase the material recycling.However,due to the lack of systematic characteristic analysis and modification methods,poor quality of CBp limits the improvement of ELTs pyrolysis in industry applications,which plays a crucial role in the economic feasibility of pyrolysis process.In this review,we have summarized the state-of-the-art characteristics and modification methodologies of the upgrading of CBp,to in-depth understand the surface microstructures and physiochemical properties o f CBp for the foundation for modification afterwards.By virtue of the proper selection of modification methods and modifying agents,the new generation of multifunctional carbon materials with desired properties can be instead of the traditional materials of CB,promising broader and various application fields. | Jiaxue Yu Junqing Xu Zhenchen Li Wenzhi He Juwen Huang Junshi Xu Guangming Li | 2020 | Frontiers of Environmental Science & Engineering2020，14，2： | 1 |

| 10 | Effects of dietary replacement of soybean meal with dried distillers grains with solubles on the microbiota occupying different ecological niches in the rumen of growing Hu lambs显示文摘Background:Diet has a profound impact on the rumen microbiota,and the impact can vary among the different rumen ecological niches(REN).This study investigated the effects of dietary replacement of soybean meal(SBM)with dried distillers grains with solubles(DDGS)on the rumen microbiota occupying different REN of growing Hu lambs.After a 9-week feeding trial,6 lambs from each dietary treatment(SBM vs.DDGS-based diets)were slaughtered for sample collection.The microbiota of the rumen solid,liquid,and epithelium fractions was examined using amplicon sequencing analysis of bacterial 16S rRNA gene,functional prediction,and qPCR.Results:No interaction of dietary protein source(PS)and REN were detected for virtually all the measurements made in this study.The DDGS substitution resulted in very limited influence on bacterial community structure.However,the metabolic pathways predicted from 16S rRNA gene sequences varied greatly between SBM-and DDGS-based diets.The populations of rumen total bacteria,fungi,sulfate-reducing bacteria(SRB),and methanogens were not influenced by DDGS substitution,but the population of protozoa was reduced.The bacterial communities in rumen solid(RS)and liquid(RL)were similar in taxonomic composition but were different in relative abundance of some taxa.In contrast,the bacterial composition and relative abundance of rumen epithelium(RE)were greatly distinct from those of the RS and the RL.In alignment with the bacterial relative abundance,the metabolic pathways predicted from 16S rRNA genes also varied greatly among the different REN.The populations of total bacteria,protozoa,and methanogens attached to the RE were smaller than those in the RS and RL,and the fungal population on the rumen epitheliumwas smaller than that in the RS but similar to that in the RL.On the contrary,the SRB population on the RE was greater than that in the RS and RL.Conclusions:Substitution of SBM with DDGS had greater impact to the protozoa than to the other microbes,and the microbial community structure and functions at different REN are distinct and niche-adapted. | Junshi Shen Zhipeng Li Zhongtang Yu Weiyun Zhu | 2021 | Journal of Animal Science and Biotechnology2021，12，2： | 1 |

| 12 | Energy harvesting performance of viscoelastic polyacrylic dielectric elastomers显示文摘Viscoelasticity dissipates the mechanical energy,leading to a reduction of energy conversion efficiency in both dielectric elastomer(DE)actuators and generators.By measuring the uniaxial tension-recovery experiments of very-high-bond-based DE,this article quantitatively presents the effect of viscoelasticity on energy harvesting performance of DE generators.By employing a DE strip energy harvester with constant surface charge,an analytical model is established to calculate the generated electrical energy and energy conversion efficiency.Numerical results demonstrate that viscoelasticity has a significant influence on DE energy harvesting performance. | Junshi Zhang Yongquan Wang Hualing Chen Bo Li | 2015 | International Journal of Smart and Nano Materials2015，6，3： | 0 |
| 13 | Mechanisms and influencing factors of the oil bank in fire flooding显示文摘Based on the systematic summary of current research on oil bank, the definition of oil bank in the process of fire flooding and its quantitative indices were proposed; and a new one-dimensional positive dry-fire flooding model considering temperature gradient was established based on the steady flow theory of gas and liquid phases. Single factor analysis and orthogonal experiments were adopted to verify the reliability and reveal the formation mechanisms and the controlling factors of the oil bank. Then the optimal conditions for the oil bank to form were discussed. The study results show the formation of the oil bank is controlled by 3 factors:(1) Oil bank would come into being within a certain temperature interval and above a critical value of temperature gradient(absolute value), with temperature too high or too low and temperature gradient absolute value lower than the critical value, the oil bank couldn't form.(2) For fire flooding process in heavy oil reservoirs, the viscosity of oil influences the width of oil bank and the speed at which oil bank forms; the lower the oil viscosity is, the wider the oil bank is and the faster the oil bank forms.(3) Oil saturation could affect the developing temperature and speed of oil bank. The favorable temperature at which oil bank develops gets lower and the accumulating speed of oil gets faster when the oil saturation is higher. By orthogonal experiments with the model, the optimal combinations of reservoir conditions for forming oil bank during fire flooding in heavy oil reservoirs can be worked out. | LI Qiu YI Leihao TANG Junshi GUAN Wenlong JIANG Youwei ZHENG Haoran ZHOU Jiuning WANG Xiaochun | 2018 | Petroleum Exploration and Development2018，45，3： | 0 |
| 14 | Temporal Memory Reinforcement Learning for the Autonomous Micro-mobile Robot Based-behavior显示文摘This paper presents temporal memory reinforcement learning for the autonomous micro-mobile robot based-behavior. Human being has a memory oblivion process, i.e. the earlier to memorize, the earlier to forget, only the repeated thing can be remembered firmly. Enlightening forms this, and the robot need not memorize all the past states, at the same time economizes the EMS memory space, which is not enough in the MPU of our AMRobot. The proposed algorithm is an extension of the Q-learning, which is an incremental reinforcement learning method. The results of simulation have shown that the algorithm is valid. | 杨玉君 Cheng Junshi Chen Jiapin Li Xiaohai | 2004 | High Technology Letters2004，10，3： | 0 |
| 15 | Association of physical activity with risk of chronic kidney disease in China:A population-based cohort study显示文摘Background:Information on the association between physical activity(PA)and the risk of chronic kidney disease(CKD)is limited.We aimed to explore the associations of total,domain-specific,and intensity-specific PA with CKD and its subtypes in China.Methods:The study included 475,376 adults from the China Kadoorie Biobank aged 30-79 years during 2004-2008 at baseline.An interviewer-administered questionnaire was used to collect the information about PA,which was quantified as metabolic equivalent of task hours per day(MET-h/day)and categorized into 4 groups based on quartiles.Cox regression was used to analyze the association between PA and CKD risk.Results:During a median follow-up of 12.1 years,5415 incident CKD cases were documented,including 1159 incident diabetic kidney disease(DKD)cases and 362 incident hypertensive nephropathy(HTN)cases.Total PA was inversely associated with CKD risk,with an adjusted hazard ratio(HR,95%confidence interval(95%CI))of 0.83(0.75-0.92)for incident CKD in the highest quartile of total PA as compared with participants in the lowest quartile.Similar results were observed for risk of DKD and HTN,and the corresponding HRs(95%CIs)were 0.75(0.58-0.97)for DKD risk and 0.56(0.37-0.85)for HTN risk.Increased nonoccupational PA,low-intensity PA,and moderate-to-vigorous-intensity PA were significantly associated with a decreased risk of CKD,with HRs(95%CIs)of 0.80(0.73-0.88),0.85(0.77-0.94),and 0.85(0.76-0.95)in the highest quartile,respectively.Conclusion:PA,including nonoccupational PA,low-intensity PA,and moderate-to-vigorous-intensity PA,was inversely associated with the risk of CKD,including DKD,HTN,and other CKD,and such associations were dose dependent. | Kexiang Shi Yunqing Zhu Jun Lv Dianjianyi Sun Pei Pei Huaidong Du Yiping Chen Ling Yang Bing Han Rebecca Stevens Junshi Chen Zhengming Chen Liming Li Canqing Yu China Kadoorie Biobank collaborative group | 2024 | Journal of Sport and Health Science2024，13，2： | 0 |
| 16 | Local field potentials,spiking activity,and receptive fields in human visual cortex显示文摘The concept of receptive field(RF) is central to sensory neuroscience. Neuronal RF properties have been substantially studied in animals,while those in humans remain nearly unexplored. Here, we measured neuronal RFs with intracranial local field potentials(LFPs) and spiking activity in human visual cortex(V1/V2/V3). We recorded LFPs via macro-contacts and discovered that RF sizes estimated from lowfrequency activity(LFA, 0.5–30 Hz) were larger than those estimated from low-gamma activity(LGA, 30–60 Hz) and high-gamma activity(HGA, 60–150 Hz). We then took a rare opportunity to record LFPs and spiking activity via microwires in V1 simultaneously. We found that RF sizes and temporal profiles measured from LGA and HGA closely matched those from spiking activity. In sum, this study reveals that spiking activity of neurons in human visual cortex could be well approximated by LGA and HGA in RF estimation and temporal profile measurement, implying the pivotal functions of LGA and HGA in early visual information processing. | Lu Luo Xiongfei Wang Junshi Lu Guanpeng Chen Guoming Luan Wu Li Qian Wang Fang Fang | 2024 | Science China(Life Sciences)2024，67，3： | 0 |
| 17 | Experimental investigation on electromechanical deformation of dielectric elastomers under different temperatures显示文摘Under an applied voltage, dielectric elastomers(DEs) produce an actuation strain that is nonlinear, partly because of the material properties. In this study, an experimental characterization is conducted to evaluate how the ambient temperature and pre-stretch affected the actuation performance. For DEs with a pre-stretch of 2 × 2, an increase of temperature from-10° to 80° results in a variation in the actuation strain of more than 1700%. Low pre-stretched DEs are more susceptible to temperature change; while highly pre-stretched DEs are relatively insensitive to temperature, because in this case the energy conversion was dominated by mechanical stretching, rather than thermal conduction, during the actuation. | Lei Liu Hualing Chen Bo Li Junjie Sheng Junshi Zhang Chi Zhang Yanjie Wang Dichen Li | 2015 | Theoretical & Applied Mechanics Letters2015，5，4： | 0 |
