| 1 | A Brief Review on the Mechanisms of miRNA Regulation显示文摘MicroRNAs (miRNAs) are a class of short,endogenously-initiated non-coding RNAs that post-transcriptionally control gene expression via either translational repression or mRNA degradation.It is becoming evident that miRNAs are playing significant roles in regulatory mechanisms operating in various organisms,including developmental timing and host-pathogen interactions as well as cell differentiation,proliferation,apoptosis and tumorigenesis.Likewise,as a regulatory element,miRNA itself is coordinatively modulated by multifarious effectors when carrying out basic functions,such as SNP,miRNA editing,methylation and circadian clock.This mini-review summarized the current understanding of interactions between miRNAs and their targets,including recent advancements in deciphering the regulatory mechanisms that control the biogenesis and functionality of miRNAs in various cellular processes. | Yimei Cai Xiaomin Yu Songnian Hu Jun Yu | 2009 | Genomics, Proteomics & Bioinformatics2009,7,4: | 55 |
| 2 | Tectonic evolution of the Western Kunlun orogenic belt in northern Qinghai-Tibet Plateau:Evidence from zircon SHRIMP and LA-ICP-MS U-Pb geochronology显示文摘The Western Kunlun Range in northern Qinghai-Tibet Plateau is composed of the North Kunlun Terrane,the South Kunlun Terrane and the Karakorum-Tianshuihai Terrane. Here we report zircon SHRIMP and LA-ICP-MS U-Pb ages of some metamorphic and igneous rocks and field observations in order to pro-vide a better understanding of their Precambrian and Palaeozoic-early Mesozoic tectonic evolution. Based on these data we draw the following conclusions: (1) The paragneisses in the North Kunlun Terrane are likely of late Mesoproterozoic age rather than Palaeoproterozoic age as previously thought,representing tectonothermal episodes at 1.0―0.9 Ga and ~0.8 Ga. (2) The North Kunlun Terrane was an orogenic belt accreted to the southern margin of Tarim during late Mesoproterozoic to early Neopro-terozoic,the two episodes of metamorphisms correspond to the assemblage and breakup of Rodinia respectively. (3) The Bulunkuole Group in western South Kunlun Terrane,which was considered to be the Palaeoproterozoic basement of the South Kunlun Terrane by previous studies,is now subdivided into the late Neoproterzoic to early Palaeozoic paragneisses (khondalite) and the early Mesozoic metamorphic volcano-sedimentary series; the paragneisses were thrust onto the metamorphic vol-cano-sedimentary series from south to north,with two main teconothermal episodes (i.e.,Caledonian,460―400 Ma,and Hercynian-Indosinian,340―200 Ma),and have been documented by zircon U-Pb ages. (4) In the eastern part of the South Kunlun Terrane,a gneissic granodiorite pluton,which intruded the khondalite,was crystallized at ca. 505 Ma and metamorphosed at ca. 240 Ma. In combination with geochronology data of the paragneiss,we suggest that the South Kunlun Terrane was a Caledonian accretionary orogenic belt and overprinted by late Paleozoic to early Mesozoic arc magmatism. | ZHANG ChuanLin LU SongNian YU HaiFeng YE HaiMin | 2007 | Science China Earth Sciences2007,50,6: | 45 |

| 4 | 时空数据模型综述显示文摘虽然相对传统的GIS数据模型而言,人们对时空数据模型的研究起步较晚,但是大量的时空数据模型已经被提出了。在综述已有时空数据模型时,就如何区别时空数据模型的异同,众多研究人员和学者更多地是比较模型优缺点或罗列和陈述各模型针对某一案例的实践和应用,而没有阐述模型间的本质区别,没有过多地解释模型扩展及其关联性,也就无法跟踪已有模型的扩展、变异和发展趋势,最终导致在选择模型的应用、实践和整合其他非-时空数据模型时,不能做出最优抉择。与众多相关时空数据模型的综述文献不同,本文进一步提升和归纳已有模型,主要集中叙述众多相关时空数据模型的扩展和关联性,阐述模型间的本质区别,呈现模型的演变过程,从而为人们在应用和实践时空数据模型时提供科学的指导,为模型的扩展和新模型的研究提供理论依据和参考。 | 陈新保 Songnian Li 朱建军 陈建群 | 2009 | 地理科学进展2009,28,1: | 22 |
| 5 | Biomonitoring for traditional herbal medicinal products using DNA metabarcoding and single molecule, real-time sequencing显示文摘Global concerns have been paid to the potential hazard of traditional herbal medicinal products(THMPs). Substandard and counterfeit THMPs, including traditional Chinese patent medicine, health foods, dietary supplements, etc. are potential threats to public health. Recent marketplace studies using DNA barcoding have determined that the current quality control methods are not sufficient for ensuring the presence of authentic herbal ingredients and detection of contaminants/adulterants. An efficient biomonitoring method for THMPs is of great needed. Herein, metabarcoding and single-molecule, realtime(SMRT) sequencing were used to detect the multiple ingredients in Jiuwei Qianghuo Wan(JWQHW), a classical herbal prescription widely used in China for the last 800 years. Reference experimental mixtures and commercial JWQHW products from the marketplace were used to confirm the method. Successful SMRT sequencing results recovered 5416 and 4342 circular-consensus sequencing(CCS) reads belonging to the ITS2 and psb A-trn H regions. The results suggest that with the combination of metabarcoding and SMRT sequencing, it is repeatable, reliable, and sensitive enough to detect species in the THMPs, and the error in SMRT sequencing did not affect the ability to identify multiple prescribed species and several adulterants/contaminants. It has the potential for becoming a valuable tool for the biomonitoring of multi-ingredient THMPs. | Tianyi Xin Zhichao Xu Jing Jia Christine Leon Songnian Hu Yulin Lin Subramanyam Ragupathy Jingyuan Song Steven G.Newmaster | 2018 | Acta Pharmaceutica Sinica B2018,8,3: | 22 |
| 6 | 基于对象-事件-过程的时空数据模型及其应用显示文摘根据地理本体思想,提出和构建了基于对象-事件-过程的面向对象的时空数据模型。该模型基于3个基本地理实体类型:地理对象、地理事件和地理过程,三者基于地理本体的特性,本体化地表达和概括了地理现象和事物。该模型能有效地描述和表达复杂的地理动态现象和事物,能增强性的探讨和表征地理现象发生和发展的内在关联。甚者,鉴于描述和表达三者的侧重点不同,该模型可灵动性地整合或拆分成其它时空数据模型,不失为一种通用的时空数据模型。最后,以动态变化的海冰为例,验证了模型的可行性和有效性。 | 陈新保 Songnian Li 李黎 李妹 | 2013 | 地理与地理信息科学2013,29,3: | 17 |
| 7 | The HuangZaoSi Maize Genome Provides Insights into Genomic Variation and Improvement History of Maize显示文摘Maize is a globally important crop that was a classic model plant for genetic studies. Here, we report a 2.2 Gb draft genome sequence of an elite maize line, HuangZaoSi (HZS). Hybrids bred from HZS-improved lines (HILs) are planted in more than 60% of maize fields in China. Proteome clustering of six completed sequeneed maize genomes show that 638 proteins fall into 264 HZS-specific gene families with the majority of contributions from tandem duplication events. Resequencing and comparative analysis of 40 HZSrelated lines reveals the breeding history of HILs. More than 60% of identified selective sweeps were clustered in identity.by.descent conserved regions, and yield-related genes/QTLs were enriched in HZS characteristic selected regions. Furthermore, we dem on strated that HZS-specific family genes were not uniformly distributed in the genome but enriched in improvement/function.related genomic regions. This study provides an important and novel resource for maize genome research and expands our knowledge on the breadth of genomic variation and improvement history of maize. | Chunhui Li Wei Song Yingfeng Luo Shenghan Gao Ruyang Zhang Zi Shi Xiaqing Wang Ronghuan Wang Fengge Wang Jidong Wang Yanxin Zhao Aiguo Su Shuai Wang Xin Li Meijie Luo Shuaishuai Wang Yunxia Zhang Jianrong Ge Xinyu Tan Ye Yuan Xiaochun Bi Hang He Jianbing Yan Yuandong Wang Songnian Hu Jiuran Zhao | 2019 | Molecular Plant2019,12,3: | 15 |
| 8 | Rice Expression Database(RED):An integrated RNA-Seq-derived gene expression database for rice显示文摘Rice is one of the most important stable food as well as a monocotyledonous model organism for the plant research community.Here,we present RED(Rice Expression Database;http://gffzzd1bc3ab4bbbc4005hwxvk9knqp5fx6bcx.ffgz.tsg.suse.edu.cn),an integrated database of rice gene expression profiles derived entirely from RNA-Seq data.RED features a comprehensive collection of 284 high-quality RNA-Seq experiments,integrates a large number of gene expression profiles and covers a wide range of rice growth stages as well as various treatments.Based on massive expression profiles,RED provides a list of housekeeping and tissue-specific genes and dynamically constructs co-expression networks for gene(s) of interest.Besides,it provides user-friendly web interfaces for querying,browsing and visualizing expression profiles of concerned genes.Together,as a core resource in BIG Data Center,RED bears great utility for characterizing the function of rice genes and better understanding important biological processes and mechanisms underlying complex agronomic traits in rice. | Lin Xia Dong Zou Jian Sang Xingjian Xu Hongyan Yin Mengwei Li Shuangyang Wu Songnian Hu Lili Hao Zhang Zhang | 2017 | Journal of Genetics and Genomics2017,44,5: | 12 |
| 9 | Fine-Tuning of MiR528 Accumulation Modulates Flowering Time in Rice显示文摘In plants,microRNA (miRNA) functions in the post-transcriptional repression of target mRNAs have been well explored.However,the mechanisms regulating the accumulation of miRNAs remain poorly under.stood.Here,we report that distinct mechanisms regulate accumulation of a monocot-specific miRNA,rice (Oryza sativa) miR528.At the transcriptional level,miR528 accumulated to higher levels in older plants than in young seedlings and exhibited aging-modulated gradual accumulation and diurnal rhythms in leaves;at the post-transcriptional level,aging also modulated miR528 levels by enhancing pri-miR528 alter.native splicing.We found that miR528 promotes rice flowering under long-day conditions by targeting RED AND FAR-RED INSENSITIVE2 (OsRFI2).Moreover,natural variations in the MIR528 promoter region caused differences in miR528 expression among rice varieties,which are correlated with their different binding affinities with the transcription factor OsSPL9 that activates the expression of miR528.Taken together,our findings reveal rice plants have evolved sophisticated modes fine-tuning miR528 levels and provide insight into the mechanisms that regulate MIRNA expression in plants. | Rongxin Yang Pingchuan Li Hailiang Mei Dong Wang Jing Sun Chao Yang Lili Hao Shouyun Cao Chengcai Chu Songnian Hu Xianwei Song Xiaofeng Cao | 2019 | Molecular Plant2019,12,8: | 12 |
| 10 | The apricot(Prunus armeniaca L.)genome elucidates Rosaceae evolution and beta-carotenoid synthesis显示文摘Apricots,scientifically known as Prunus armeniaca L,are drupes that resemble and are closely related to peaches or plums.As one of the top consumed fruits,apricots are widely grown worldwide except in Antarctica.A high-quality reference genome for apricot is still unavailable,which has become a handicap that has dramatically limited the elucidation of the associations of phenotypes with the genetic background,evolutionary diversity,and population diversity in apricot.DNA from P.armeniaca was used to generate a standard,size-selected library with an average DNA fragment size of~20 kb.The library was run on Sequel SMRT Cells,generating a total of 16.54 Gb of PacBio subreads(N50=13.55 kb).The high-quality P.armeniaca reference genome presented here was assembled using long-read single-molecule sequencing at approximately 70×coverage and 171×Illumina reads(40.46 Gb),combined with a genetic map for chromosome scaffolding.The assembled genome size was 221.9 Mb,with a contig NG50 size of 1.02 Mb.Scaffolds covering 92.88%of the assembled genome were anchored on eight chromosomes.Benchmarking Universal Single-Copy Orthologs analysis showed 98.0%complete genes.We predicted 30,436 protein-coding genes,and 38.28%of the genome was predicted to be repetitive.We found 981 contracted gene families,1324 expanded gene families and 2300 apricot-specific genes.The differentially expressed gene(DEG)analysis indicated that a change in the expression of the 9-cis-epoxycarotenoid dioxygenase(NCED)gene but not lycopene beta-cyclase(LcyB)gene results in a lowβ-carotenoid content in the white cultivar“Dabaixing”.This complete and highly contiguous P.armeniaca reference genome will be of help for future studies of resistance to plum pox virus(PPV)and the identification and characterization of important agronomic genes and breeding strategies in apricot. | Fengchao Jiang Junhuan Zhang Sen Wang Li Yang Yingfeng Luo Shenghan Gao Meiling Zhang Shuangyang Wu Songnian Hu Haoyuan Sun Yuzhu Wang | 2019 | Horticulture Research2019,6,1: | 9 |
| 11 | Long Non-coding RNAs and Their Biological Roles in Plants显示文摘With the development of genomics and bioinformatics, especially the extensive applications of high-throughput sequencing technology, more transcriptional units with little or no protein-coding potential have been discovered. Such RNA molecules are called nonprotein-coding RNAs(npc RNAs or nc RNAs). Among them, long npc RNAs or nc RNAs(lnpc RNAs or lnc RNAs) represent diverse classes of transcripts longer than 200 nucleotides. In recent years, the lnc RNAs have been considered as important regulators in many essential biological processes. In plants, although a large number of lnc RNA transcripts have been predicted and identified in few species, our current knowledge of their biological functions is still limited.Here, we have summarized recent studies on their identification, characteristics, classification,bioinformatics, resources, and current exploration of their biological functions in plants. | Xue Liu Lili Hao Dayong Li Lihuang Zhu Songnian Hu | 2015 | Genomics, Proteomics & Bioinformatics2015,13,3: | 9 |
| 12 | Polarization-maintaining few mode fiber composed of a central circular-hole and an elliptical-ring core显示文摘We propose a novel waveguide design of polarization-maintaining few mode fiber(PM-FMF) supporting ≥10non-degenerate modes, utilizing a central circular air hole and a circumjacent elliptical-ring core. The structure endows a new degree of freedom to adjust the birefringence of all the guided modes, including the fundamental polarization mode. Numerical simulations demonstrate that, by optimizing the air hole and elliptical-ring core,a PM-FMF supporting 10 distinctive polarization modes has been achieved, and the effective index difference Δn_(eff) between the adjacent guided modes could be kept larger than 1.32 × 10^(-4) over the whole C +L band. The proposed fiber structure can flexibly tailored to support an even larger number of modes in PM-FMF(14-mode PM-FMF has been demonstrated as an example), which can be readily applicable to a scalable mode division multiplexing system. | JIAJIA ZHAO MING TANG KYUNGHWAN OH ZHENHUA FENG CAN ZHAO RUOLIN LIAO SONGNIAN FU PERRY PING SHUM DEMING LIU | 2017 | Photonics Research2017,5,3: | 9 |
| 13 | Analysis of ESTs and gene expression patterns of the posterior silkgland in the fifth instar larvae of silkworm, Bombyx mori L.显示文摘The fibroin gene expression pattern and regulation of the posterior silkgland were studied by means of expressed sequence tags (ESTs) using the first and fifth day larvae of the fifth instar of silkworm, Bombyx mori L (strain: C 108). The results showed that there were 911 repetitive ESTs and 1950 single sequences (Singlets) among total 2861 consentient sequences, which were spliced. 1335 sequences were identified and the other 1526 were unknown. 5560 sequences (55.89%) in the posterior silkgland cell of the silkworm were new ESTs without homology with EST data published by Mita et al. The number of repetitive ESTs and single sequences from the first day larvae of the fifth instar was double more than that of the fifth day of the same instar in the silkworms. The unigenes which were more than 50 in repetitive EST size (contig size) came to only about 0.5% in total consentient sequences. There were significant differences between gene expression frequencies, and expressed genes were related to fibroin synthesis and its secretion and fibroin composition. Comparing the fifth day with the first day of the fifth instar, the genes-expressed quantity of fibroin heavy-chain gene was 18 fold higher, fibroin light-chain gene 9 fold and fibroin P52 gene 8 fold. 508 genes functioned for cellular component and 315 for enzyme after function tracing. These results implied that the gene expression of the first day was mainly for preparation for fibroin synthesis except for the growth of silkgland cells, and the gene expression of the fifth day of the fifth instar was mainly for synthesizing and excreting fibroin. Because the ratio of heavy chain, light chain and p25 of fibroin was not 6:6:1 as theoretically expected, or its special H-chain structure, the H-chain gene was not easy to detect through EST technique. Most of genes among total 2861 consentient sequences functioned for fibroin synthesis and secretion. This suggested the fibroin synthesis and secretion procedure of the posterior silkgland was more complex than the knowledge we have. | ZHONG Boxiong, YU Yingpo, XU Yusong, YU Hong, LU Xingmeng, MIAO Yungen, YANG Jun, XU Hao, HU Songnian & LOU Chengfu College of Animal Sciences, Zhejiang University, Hangzhou 310029, China Hangzhou Huada Gene Research and Development Center, Southern Base of Genomic Information, Chinese Academy of Sciences, Hangzhou 310007, China | 2005 | Science China(Life Sciences)2005,48,1: | 8 |
| 14 | Transcriptome profiling of the developing postnatal mouse testis using next-generation sequencing显示文摘Mammalian testis development is a complex and highly sophisticated process. To study the dynamic change of normal testis development at the transcriptional level, we investigated mouse testes at three postnatal ages: 6 days postnatal, 4 weeks old, and 10 weeks old, representing infant (PN1), juvenile (PN2), and adult (PN3) stages, respectively. Using ultra high-throughput RNA sequencing (RNA-seq) technology, we obtained 211 million reads with a length of 35 bp. We identified 18837 genes that were expressed in mouse testes, and found that genes expressed at the highest level were involved in spermatogenesis. The gene expression pattern in PN1 was distinct from that in PN2 and PN3, which indicates that spermatogenesis has commenced in PN2. We analyzed a large number of genes related to spermatogenesis and somatic development of the testis, which play important roles at different developmental stages. We also found that the MAPK, Hedgehog, and Wnt signaling pathways were significantly involved at different developmental stages. These findings further our understanding of the molecular mechanisms that regulate testis development. Our study also demonstrates significant advantages of RNA-seq technology for studying transcriptome during development. | GONG Wei PAN LinLin LIN Qiang ZHOU YuanYuan XIN ChengQi YU XiaoMin CUI Peng HU SongNian YU Jun | 2013 | Science China(Life Sciences)2013,56,1: | 8 |
| 15 | A Comprehensive Transcriptomic Analysis of Infant and Adult Mouse Ovary显示文摘Ovary development is a complex process involving numerous genes. A well-developed ovary is essential for females to keep fertility and reproduce offspring. In order to gain a better insight into the molecular mechanisms related to the process of mammalian ovary development,we performed a comparative transcriptomic analysis on ovaries isolated from infant and adult mice by using next-generation sequencing technology(SOLi D). We identified 15,454 and 16,646 transcriptionally active genes at the infant and adult stage, respectively. Among these genes, we also identified 7021 differentially expressed genes. Our analysis suggests that, in general, the adult ovary has a higher level of transcriptomic activity. However, it appears that genes related to primordial follicle development, such as those encoding Figla and Nobox, are more active in the infant ovary,whereas expression of genes vital for follicle development, such as Gdf9, Bmp4 and Bmp15, is upregulated in the adult. These data suggest a dynamic shift in gene expression during ovary development and it is apparent that these changes function to facilitate follicle maturation, when additional functional gene studies are considered. Furthermore, our investigation has also revealed several important functional pathways, such as apoptosis, MAPK and steroid biosynthesis, that appear to be much more active in the adult ovary compared to those of the infant. These findings will provide a solid foundation for future studies on ovary development in mice and other mammals and help to expand our understanding of the complex molecular and cellular events that occur during postnatal ovary development. | Linlin Pan Wei Gong Yuanyuan Zhou Xiaonuan Li Jun Yu Songnian Hu | 2014 | Genomics, Proteomics & Bioinformatics2014,12,5: | 7 |
| 16 | Micro RNA profiles and potential regulatory pattern during the early stage of spermatogenesis in mice显示文摘Spermatogenesis is a complicated and poorly understood process that relies on the precise regulation of the self-renewal and differentiation of spermatogonia. In many organisms, micro RNAs(mi RNAs) are involved in multiple developmental processes as critical regulators of transcriptional and post-transcriptional gene silencing. This study investigated the expression pattern of mi RNAs in type B spermatogonia cells(BSc) and primary spermatocytes(PSc) of mice, using a high-throughput small RNA sequencing system. The results revealed that the expression levels of Let-7 family mi RNAs were remarkably high in both cell types. Furthermore, the expression levels of mi R-21, mi R-140-3p, mi R-103, mi R-30 a, mi R-101 b and mi R-99 b were decreased during the transformation from BSc to PSc. These mi RNAs target vital genes that participate in apoptosis, cell proliferation and differentiation, junction assembly and cell cycle regulation. These results highlight the indispensable role of mi RNAs in spermatogenesis. | LUO MengMeng HAO LiLi HU Fen DONG YaNan GOU LiXia ZHANG WenDian WANG Xin ZHAO YuHui JIA MengChun HU SongNian ZHANG XiuJun | 2015 | Science China(Life Sciences)2015,58,5: | 6 |

| 18 | Distributed Brillouin frequency shift extraction via a convolutional neural network显示文摘Distributed optical fiber Brillouin sensors detect the temperature and strain along a fiber according to the local Brillouin frequency shift(BFS),which is usually calculated by the measured Brillouin spectrum using Lorentzian curve fitting.In addition,cross-correlation,principal component analysis,and machine learning methods have been proposed for the more efficient extraction of BFS.However,existing methods only process the Brillouin spectrum individually,ignoring the correlation in the time domain,indicating that there is still room for improvement.Here,we propose and experimentally demonstrate a BFS extraction convolutional neural network(BFSCNN)to retrieve the distributed BFS directly from the measured two-dimensional data.Simulated ideal Brillouin spectra with various parameters are used to train the BFSCNN.Both the simulation and experimental results show that the extraction accuracy of the BFSCNN is better than that of the traditional curve fitting algorithm with a much shorter processing time.The BFSCNN has good universality and robustness and can effectively improve the performances of existing Brillouin sensors. | YIQING CHANG HAO WU CAN ZHAO LI SHEN SONGNIAN FU MING TANG | 2020 | Photonics Research2020,8,5: | 6 |
| 19 | Characterization of miRNomes in Acute and Chronic Myeloid Leukemia Cell Lines显示文摘Myeloid leukemias are highly diverse diseases and have been shown to be associated with microRNA(miRNA) expression aberrations. The present study involved an in-depth miRNome analysis of two human acute myeloid leukemia(AML) cell lines, HL-60 and THP-1, and one human chronic myeloid leukemia(CML) cell line, K562, via massively parallel signature sequencing. mRNA expression profiles of these cell lines that were established previously in our lab facilitated an integrative analysis of miRNA and mRNA expression patterns. miRNA expression profiling followed by differential expression analysis and target prediction suggested numerous miRNA signatures in AML and CML cell lines. Some miRNAs may act as either tumor suppressors or oncomiRs in AML and CML by targeting key genes in AML and CML pathways. Expression patterns of cell type-specific miRNAs could partially reflect the characteristics of K562, HL-60 and THP-1 cell lines, such as actin filament-based processes, responsiveness to stimulus and phagocytic activity. miRNAs may also regulate myeloid differentiation, since they usually suppress differentiation regulators. Our study provides a resource to further investigate the employment of miRNAs in human leukemia subtyping, leukemogenesis and myeloid development. In addition, the distinctive miRNA signatures may be potential candidates for the clinical diagnosis, prognosis and treatment of myeloid leukemias. | Qian Xiong Yadong Yang Hai Wang Jie Li Shaobin Wang Yanming Li Yaran Yang Kan Cai Xiuyan Ruan Jiangwei Yan Songnian Hu Xiangdong Fang | 2014 | Genomics, Proteomics & Bioinformatics2014,12,2: | 6 |
| 20 | Electron beam welding of Re and BT5-1 titanium alloy显示文摘Based on the binary alloy phase diagram of Re-Ti, the weldability of Re and BT5-1 titanium alloy was analyzed.Using two methods of direct electron beam welding (EBW-D) and intergradation electron beam welding (EBW-I), Re andBT5-1 was welded. Experimental results show that the joint figuration of EBW-D between Re and BT5-1 is not fine, andthe joint is inclined to brittleness rupture. The joint figuration of EBW-I between Re and BT5-1 is fine. No cracking andother disfigures occur in the intergradation joint. The element distribution of Re, Me, and Ti in the weld metal is progres-sional diversification. | YANG Shanglei XUE Xiaohuai LOU Songnian CHEN Yan LI Shimin | 2005 | Rare Metals2005,24,3: | 5 |
