| 1 | L-type calcium current in right ventricular outflow tract myocytes of rabbit heart显示文摘The mechanism of idiopathic ventricular tachycardia originating from the right ventricular outflow tract (RVOT) is not clear. Many clinical reports have suggested a mechanism of triggered activity. However, there are few studies investigating this because of the technical difficulties associated with examining this theory. The L-type calcium current (ICa-L), an important inward current of the action potential (AP), plays an important role in arrhythmogenesis. The aim of this study was to explore differences in the APs of right ventricular (RV) and RVOT cardiomyocytes, and differences in electrophysiological characteristics of the ICa-L in these myocytes. Rabbit RVOT and RV myocytes were isolated and their AP and ICa-L were investigated using the patch-clamp technique. RVOT cardiomyocytes had a wider range of AP duration (APD) than RV cardiomyocytes, with some markedly prolonged APDs and markedly shortened APDs. The markedly shortened APDs in RVOT myocytes were abolished by treatment with 4-AP, an inhibitor of the transient outward potassium current, but the markedly prolonged APDs remained, with some myocytes with a long AP plateau not repolarizing to resting potential. In addition, early afterdepolarization (EAD) and second plateau responses were seen in RVOT myocytes but not in RV myocytes. RVOT myocytes had a higher current density for ICa-L than RV myocytes (RVOT (13.16±0.87) pA pF-1, RV (8.59±1.97) pA pF-1; P<0.05). The ICa-L and the prolonged APD were reduced, and the EAD and second plateau response disappeared, after treatment with nifedipine (10 μmol L-1), which blocks the ICa-L. In conclusion, there was a wider range of APDs in RVOT myocytes than in RV myocytes, which is one of the basic factors involved in arrhythmogenesis. The higher current density for ICa-L is one of the factors causing prolongation of the APD in RVOT myocytes. The combination of EAD with prolonged APD may be one of the mechanisms of RVOT-VT generation. | LIANG ShengHui LIN ChenHui LI Yuan LIU TaiFeng WANG Yan | 2012 | Science China(Life Sciences)2012，55，1： | 3 |
| 2 | Flexible bioelectronics for physiological signals sensing and disease treatment显示文摘Flexible bioelectronics,including wearable and implantable electronics,have revolutionized the way of human-machine interaction due to the fact that they can provide natural and seamless interactions with humans and keep stable and durable at strained states.As sensor elements or biomimetic actuators,flexible bioelectronics can dynamically sense and monitor physiological signals,reveal real-time physical health information and provide timely precise stimulations or treatments.Thus,the flexible bioelectronics are playing increasingly important roles in human-health monitoring and disease treatment,which will significantly change the future of healthcare as well as our relationships with electronics.This review summarizes recent major progress in the development of flexible substrates or encapsulation materials,sensors,circuits and energy-autonomous powers toward digital healthcare monitoring,emphasizing its role in biomedical applications in vivo and problems in practical applications.A future perspective into the challenges and opportunities in emerging flexible bioelectronics designs for the next-generation healthcare monitoring systems is also presented. | Guang Yao Chenhui Yin Qian Wang Tianyao Zhang Sihong Chen Chang Lu Kangning Zhao Weina Xu Taisong Pan Min Gao Yuan Lin | 2020 | Journal of Materiomics2020，6，2： | 2 |
| 3 | Transcriptome and Metabolome Analyses of Sea Cucumbers Apostichopus japonicus in Southern China During the Summer Aestivation Period显示文摘Aestivation is a common strategy of sea cucumbers(Apostichopus japonicus)in response to high-temperature conditions.Previous studies have individually investigated the immune and physiological alterations at the aestivation stage.However,these studies have not evaluated the relationship between immunity and physiology.In this study,we explored the transcriptome and metabolome of A.japonicus during the aestivation stage to study the relationship.The transcriptome analysis of dormant(aestivation)and revived A.japonicus generated 2368 differentially expressed genes,including 927 downregulated genes and 1441 upregulated genes.Based on Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses,the downregulated genes in the dormant group were found to be involved in DNA replication,RNA metabolic process,and protein metabolism,which results in the inhibition of motility,skeletal development,neural activity,cell proliferation,and development of A.japonicus.In contrast,the upregulated genes were found to be associated with fatty acid metabolism,carbohydrate hydrolysis,and phagocytosis.In the metabolome analysis,the downregulated metabolites were found to be associated with fatty acid metabolism,starch and sucrose metabolism,and TCA cycle.This indicates that dormant sea cucumbers consume reserved carbohydrates and fatty acids to maintain low levels of energy supply.The protein-protein interaction network analysis further revealed that carbohydrate hydrolysis promoted phagocytosis activity in the dormant group.This study provides new insights into potential molecular mechanisms of sea cucumber survival in high-temperature conditions,which is critical in aquaculture of sea cucumbers. | YANG Qiuhua ZHANG Xusheng LU Zhen HUANG Ruifang TRAN Ngoc Tuan WU Jianshao YANG Fuyuan GE Hui ZHONG Chenhui SUN Qian ZHOU Chen LIN Qi | 2021 | Journal of Ocean University of China2021，20，1： | 2 |

| 5 | New State Recovery Attacks on the Grain v1 Stream Cipher显示文摘The Grain v1 stream cipher is one of the seven finalists in the final e STREAM portfolio. Though many attacks have been published,no recovery attack better than exhaustive key search on full Grain v1 in the single key setting has been found yet. In this paper,new state recovery attacks on Grain v1 utilizing the weak normality order of the employed keystream output function in the cipher are proposed. These attacks have remarkable advantages in the offline time,online time and memory complexities,which are all better than exhaustive key search. The success probability of each new attack is 0.632. The proposed attack primarily depends on the order of weak normality of the employed keystream output function. This shows that the weak normality order should be carefully considered when designing the keystream output functions of Grain-like stream ciphers. | Lin Ding Chenhui Jin Jie Guan Shaowu Zhang Junzhi Li Hong Wang Wei Zhao | 2016 | China Communications2016，13，11： | 1 |

| 7 | Comparative transcriptome analysis of Phascolosoma esculenta under different salinities显示文摘Salinity is an important parameter that influences the developmental progress of aquatic organisms.The larvae of Phascolosoma esculenta developed into the early stage trochosphere,the late stage trochosphere and the early stage pelagosphere in the low-salinity group(15),the middle group(22.5)and the high-salinity group(30),respectively,after being incubated for 50 h,according to morphological observation.The results showed that high salinity could accelerate the cellular development of P.esculenta.To elucidate the molecular mechanism of larval development of P.esculenta under different salinities,we performed transcriptome analysis of the larvae in P.esculenta.Nine transcriptome libraries of P.esculenta larvae were constructed,i.e.,the low-salinity group(A1,A2 and A3),the middle group(B1,B2 and B3)and the high-salinity group(C1,C2 and C3),and each group with three repeats.These nine paired-end libraries were sequenced using the Illumina HiSeq 2500 platform.In total,57.63 Gb clean data were obtained and de novo assembled into 320,527 unigenes with mean lengths of 482.62 bp and N50 of 529 bp.A total of 249,162 unigenes were significantly matched to known unique proteins.The gene ontology(GO)annotation and the Kyoto Encyclopedia of Genes and Genomes(KEGG)were used to determine the regulation pathways and candidate genes that are associated with the process of larval development.A total number of 12,811,16,991 and 1735 transcripts were identified as differentially expressed genes(DEGs)from the comparison of A vs.B,A vs.C,and B vs.C,respectively.Of these differentially expressed genes,many DEGs that were upregulated in the high-salinity group were involved in the function that controls the larval development of P.esculenta,such as the neuroactive ligand-receptor interaction and ECM-receptor interaction.In addition,the results of the transcriptome analysis were verified by quantitative real-time PCR(qRT-PCR).After morphological observation and transcriptome analysis,we think high salinity(30)is more suitable than medium(22.5)or low(15)salinity for the development of P.esculenta larvae.This information provides guidance for artificial breeding and paves the way to the further research on the individual development of P.esculenta under different salinities. | Xiangyang Lin Suzhen Deng Xiande Liu Chenhui Zhong Kun Qiao Leibin Li | 2020 | Aquaculture and Fisheries2020，5，6： | 1 |

| 10 | A common variant in AAK1 reduces risk of noise-induced hearing loss显示文摘Noise-induced hearing loss(NIHL)is one of the most common types of hearing loss and contributes to significant morbidity worldwide,as well as being the major cause of age-related hearing loss and tinnitus.The World Health Organization(WHO)estimates that 10%of the world's population is exposed to sound levels that could potentially cause NIHL[1].It has been widely accepted that NIHL is a multifactorial genetic disorder with estimated heritability of 36%to 40%[2].Ideally,identification of the modifying genetic variants would help protect individuals at high risk of NIHL.For decades,many geneticists have searched for genes that either predispose or protect from NIHL.Howeve r,the majority of genetic studies for NIHL were conducted in independent known candidate genes[3]. | Qixuan Wang Xueling Wang Tao Yang Lu Yang Huihui Liu Yihang Zheng Guixian Jiang Hongchao Liu Chenhui Huang Juan Chen Zhentao Wang Zhaoyan Wang Wei Zhao Jiannan Lin Xuejie Zhang Junbo Shi Kun Han Xingyu Le Yan Ren Yun Li Yingying Hong Wentao Shi Dongqi Cui Minfei Qian Jun Xu Xiaofei Zheng Yunge Gao Chen Li James Lin Zhiwu Huang Hao Wu | 2023 | National Science Review2023，10，7： | 0 |
| 11 | The Tianlai Cylinder Pathfinder array: System functions and basic performance analysis显示文摘The Tianlai Cylinder Pathfinder is a radio interferometer array designed to test techniques for 21 cm intensity mapping in the post-reionization Universe,with the ultimate aim of mapping the large scale structure and measuring cosmological parameters such as the dark energy equation of state.Each of its three parallel cylinder reflectors is oriented in the north-south direction,and the array has a large field of view.As the Earth rotates,the northern sky is observed by drift scanning.The array is located in Hongliuxia,a radio-quiet site in Xinjiang,and saw its first light in September 2016.In this first data analysis paper for the Tianlai cylinder array,we discuss the sub-system qualification tests,and present basic system performance obtained from preliminary analysis of the commissioning observations during 2016-2018.We show typical interferometric visibility data,from which we derive the actual beam profile in the east-west direction and the frequency band-pass response.We describe also the calibration process to determine the complex gains for the array elements,either using bright astronomical point sources,or an artificial on site calibrator source,and discuss the instrument response stability,crucial for transit interferometry.Based on this analysis,we find a system temperature of about 90 K,and we also estimate the sensitivity of the array. | JiXia Li ShiFan Zuo FengQuan Wu YouGang Wang JuYong Zhang ShiJie Sun YiDong Xu ZiJie Yu Reza Ansari YiChao Li Albert Stebbins Peter Timbie YanPing Cong JingChao Geng Jie Hao QiZhi Huang JianBin Li Rui Li DongHao Liu YingFeng Liu Tao Liu John PMarriner ChenHui Niu Ue-Li Pen Jeffery BPeterson HuLi Shi Lin Shu YaFang Song HaiJun Tian GuiSong Wang QunXiong Wang RongLi Wang WeiXia Wang Xin Wang KaiFeng Yu Jiao Zhang BoQin Zhu JiaLu Zhu XueLei Chen | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，12： | 0 |
