Abstract
Heart rate is a crucial physiological indicator for fish, but current measurement methods are often invasive or require delicate manipulation. In this study, we introduced two non-invasive and easy-to-operate methods based on photoplethysmography, namely reflectance-type photoplethysmography (PPG) and remote photoplethysmography (rPPG), which we applied to the large yellow croaker (Larimichthys crocea). PPG showed perfect synchronization with electrocardiogram (ECG), with a Pearson's correlation coefficient of 0.99999. For rPPG, the results showed good agreement with ECG. Under active provision of green light, the Pearson's correlation coefficient was 0.966, surpassing the value of 0.947 under natural light. Additionally, the root mean square error was 0.810, which was lower than the value of 1.30 under natural light, indicating not only that the rPPG method had relatively high accuracy but also that green light may have the potential to further improve its accuracy.

Abstract
Medical test results are indispensable and important tools in diagnosis and treatment services. It is necessary to promote the homogenization of test results first, because homogenization is the basis for mutual recognition of test results. Mutual recognition of medical test results can help share resources among medical institutions, provide more reliable test results for early prevention, screening and treatment of diseases, and reduce repeated tests, thus improving people's medical experience. In recent years, with the deepening of medical system reform and the promotion of graded diagnosis and treatment, governments have continuously introduced policies of mutual recognition of test results around country. However, homogenization is a prerequisite for mutual recognition of test results, with the emergence of intelligent medicine in the era of internet big data, opportunities and challenges coexist in the development of homogeneity management. In the future, the homogeneity of medical test results will present a trend of digitalization, automation, informatization and intelligence.

Abstract
The large yellow croaker (Larimichthys crocea) is one of the most economically valuable marine fish in China and is a notable species in ecological studies owing to a serious collapse of wild germplasm in the past few decades. The stock division and species distribution, which have important implications for ecological protection, germplasm recovery, and fishery resource management, have been debated since the 1960s. However, it is still uncertain even how many stocks exist in this species. To address this, we evaluated the fine-scale genetic structure of large yellow croaker populations distributed along the eastern and southern Chinese coastline based on 7.64 million SNP markers. Compared with the widely accepted stock boundaries proposed in the 1960s, our results revealed that a climate-driven habitat change probably occurred between the Naozhou (Nanhai) Stock and the Ming-Yuedong (Mindong) Stock. The boundary between these two stocks might have shifted northwards from the Pearl River Estuary to the northern area of the Taiwan Strait, accompanied by highly asymmetric introgression. In addition, we found divergent landscapes of natural selection between the stocks inhabiting northern and southern areas. The northern population exhibited highly agminated signatures of strong natural selection in genes related to developmental processes, whereas moderate and interspersed selective signatures were detected in many immune-related genes in the southern populations. These findings establish the stock status and genome-wide evolutionary landscapes of large yellow croaker, providing a basis for conservation, fisheries management and further evolutionary biology studies.

Abstract
Large yellow croaker (Larimichthys crocea) is one of the most important mariculture fish in China. However, cryptocaryonosis caused by Cryptocryon irritans infection has brought huge economic losses and threatened the healthy and sustainable development of L. crocea industry. Recently, a new C. irritans resistance strain of L. crocea (RS) has been bred using genomic selection technology in our laboratory work. However, the molecular mechanisms for C. irritans resistance of RS have not been fully understood. MicroRNAs (miRNAs) are endogenous small non-coding RNAs that are post-transcriptional regulators, and they play vital roles in immune process of bony fish. Identification of anti-C.irritans relevant miRNA signatures could, therefore, be of tremendous translational value. In the present study, integrated mRNA and miRNA expression analysis was used to explore C. irritans resistance mechanisms of the L. crocea. RS as well as a control strain (CS) of L. crocea, were artificially infected with C. irritans for 100 h, and their gill was collected at 0 h (pre-infection), 24 h (initial infection), and 72 h (peak infection) time points. The total RNA from gill tissues was extracted and used for transcriptome sequencing and small RNA sequencing. After sequencing, 23,172 known mRNAs and 289 known miRNAs were identified. The differential expression was analyzed in these mRNAs and mRNAs and the interactions of miRNA-mRNA pairs were constructed. KEGG pathway enrichment analyses showed that these putative target mRNAs of differentially expressed miRNAs (DEMs) were enriched in different immune-related pathways after C. irritans infection in RS and CS. Among them, necroptosis was the immune-related pathway that was only significantly enriched at two infection stages of RS group (RS-24 h/RS-0h and RS-72 h/RS-0h). Further investigation indicates that necroptosis may be activated by DEMs such as miR-133a-3p, miR-142a-3p and miR-135c, this promotes inflammation responses and pathogen elimination. These DEMs were selected as miRNAs that could potentially regulate the C. irritans resistance of L. crocea. Though these inferences need to be further verified, these findings will be helpful for the research of the molecular mechanism of C. irritans resistance of L. crocea and miRNA-assisted molecular breeding of aquatic animals.

Abstract
Long non-coding RNAs (lncRNAs) have several known functions in fish growth processes and signal transduction, but their possible roles in response to bacterial diseases remain largely unresolved. In this study, we report a comprehensive cold-water bacterial disease-responsive lncRNA expression profile for understanding the transcriptional regulatory mechanisms of visceral white-nodules disease resistance in large yellow croaker. A total of 2534 high-confidence lncRNAs were identified by a rigorous filtering pipeline as a basic sequence set for comparative transcriptional analysis. In addition, a total of 10,200 lncRNA-mRNA pairs with high correlation coefficients were identified by expressions level correlation analysis, including non-redundant 381 DE lncRNAs and 2590 differential expressed genes. MSTRG_11084_1 and MSTRG_20402_1 were linked to a large number of target genes and may be involved in important functions in immune regulation. We further revealed the conserved and idiosyncratic features of the disease response process between the technical control strain (TCS) and the resistant strain (RS). Immune-related pathways were enriched in GO terms and KEGG pathways, among which cytokine-cytokine receptor interaction, MAPK signaling pathway, and NF-kappa B signaling pathway may play a key role in VWND resistance in large yellow croaker. Protein-protein interaction network (PPI) analysis revealed that immune-related target genes such as il-10, met, acta2, myc, cav1, and ntrk1, as well as growth and metabolism-related target genes such as pik3r2, igf1, sc5d, hmgcr, and lss were considered the main hub genes. This study represents the first characterization of lncRNAs involved in VWND resistance in large yellow croaker and provides new clues for elucidating the disease response mechanism of large yellow croaker.

Abstract
Visceral white-nodules disease (VWND), caused by Pseudomonas plecoglossicida, is one of the primary causes of morbidity and mortality in large yellow croaker aquaculture. Host disease resistance is a heritable trait that involves complex regulatory processes. However, the regulatory mechanism of bacterial resistance in large yellow croaker is still unclear. This study attempted to systematically evaluate the major genetic loci and transcriptional regulatory mechanisms associated with the resistance to VWND in large yellow croaker by crossover method studies. A large population of large yellow croaker was challenged with P. plecoglossicida, with survival time recorded and samples were taken for genotyping. Meanwhile, spleen samples that were used for RNA-seq to compare their transcriptomic profiles before and after infection were taken from resistant populations (RS) and susceptible control populations (CS) bred using the genomic selection (GS) technique. Genome-wide association analyses using 46 K imputed SNP genotypes highlighted that resistance is a polygenic trait. The integrative analysis results show the co-localization of the cd82a gene between disease resistance-related genetic loci and comparative transcriptional analysis. And functional enrichment analysis showed differential enrichment of the p53 signaling pathway in RS and CS groups, suggesting that there may be cd82a-mediated p53 signaling pathway activation for VWND resistance. This large-scale study provides further evidence for the heritability and transcriptional regulatory mechanisms of host inheritance of VWND resistance.

Abstract
Large yellow croaker (Larimichthys crocea) is one of the most economically important fish in China. Recently, global climate change has caused more and more intense and extreme low temperature weathers, resulting in huge losses to the large yellow croaker industry. Therefore, it is essential to understand the mechanisms of low-temperature tolerance in large yellow croaker. Here, we conducted an integrative analysis of genome-wide association study (GWAS) and transcriptome analysis to identify candidate variants and reveal the molecular underpinning of cold-stress response in large yellow croaker. A total of 8 significant single nucleotide polymorphisms (SNPs) loci on 6 chromosomes were identified in the GWAS analysis, and 5764 (gill) and 3588 (liver) differentially expressed genes (DEGs) were detected in cold-stressed large yellow croaker, respectively. Further comparative and functional analysis of the candidate genes and DEGs highlighted the importance of pathways/genes related to immune response, cellular stress response, lipid transport, and metabolism in the cold-stress response of large yellow croaker. Our results provide insights into the cold tolerance of large yellow croaker and contribute to genomic-based selection for low-temperature-resistant large yellow croaker.

Abstract
The large yellow croaker (Larimichthys crocea) plays an economically vital role in the marine aquaculture in China. Suffering from infection of bacteria and protozoon, effect of extreme weather and stress from high-density farming, genome editing is thought to be an important tool applied to L. croea for enhancing commercial traits such as growth rate, disease resistance, and nutrition component. In this study, we identified two mstn genes in L. croea and investigated the different phylogenetic clades, gene structures, and conserved syntenic relationships. To obtain fast-growing large yellow croaker, we specially selected two validated targets for mstnb knockout, which was homologous to mammalian myostatin gene (MSTN) and downregulated skeletal muscle growth and development. Five significant mutation types were generated in two mosaic mutants by transferring specific CRISPR/Cas9 RNPs (ribonucleoprotein) into the one-cell fertilized embryos based on CRISPR/Cas9 technology. Subsequently, we also elucidated the obstacles and possible measures to improve the success rate of inducing modified large yellow croaker. Our results would provide valuable method and reference for facilitating genome editing programs of the large yellow croaker in the future.

Abstract
Objective: To investigate the efficacy, safety and prognostic factors of percutaneous biliary stent combined with iodine-125 seed chain brachytherapy (radiotherapy) in the treatment of malignant obstructive jaundice. Methods: Data of 107 cases with malignant obstructive jaundice treated with percutaneous biliary stent implantation from January 2017 to December 2020 were retrospectively analyzed. Among them, 58 cases received biliary stent combined with iodne-125 seed chain brachytherapy (study group), and 49 cases received biliary stent implantation (control group). The changes of bilirubin, stent patency time, complications, overall survival (OS) and prognostic factors were analyzed in both groups. Results: The incidence of complications in the study group and the control group were 17.2% and 18.3% respectively, and the difference was not statistically significant (P=0.974). Serum total bilirubin levels were decreased significantly in both groups at one month after surgery (P<0.001). Postoperative stent patency time was significantly better in the study group (10.0±1.6 months) (95% CI: 8.2~12.5) than that in the control group (5.2±0.4 months) (95% CI: 4.1~6.0, P<0.001). The median OS was longer in the study group (11.2±1.8 months) (95% CI: 9.2~12.8) than that in the control group (8.0±1.1 months) (95% CI: 8.0~12.8, P<0.001). Multivariate analysis result showed that stent combined with brachytherapy (HR=0.08, 95% CI:0.04~0.15, P<0.001) and receiving further anti-tumor therapy after surgery (HR=0.27, 95% CI:0.15~0.49, P<0.001) were independent risk factors affecting the patency of biliary stents. Preoperative percutaneous transhepatic biliary drainage (HR=0.46, 95%CI:0.28~0.74, P=0.002), stent combined with brachytherapy (HR=0.23, 95%CI:0.14~0.39, P<0.001) and receiving further anti-tumor therapy after surgery (HR=0.37, 95%CI:0.22~0.61, P<0.001) were independent risk factors affecting OS. Conclusion: Percutaneous biliary stent combined with brachytherapy is safe and effective in the treatment of malignant obstructive jaundice, which can significantly prolong the patency time of biliary stent and the survival time of patients.

Abstract
Objective: To study the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) combined with iodine-125 (125Ⅰ) seed strands implantation in patients with hepatocellular carcinoma combined with portal vein tumor thrombosis. Methods: 25 cases with diffuse intrahepatic tumor combined with tumor thrombus type Ⅲ/Ⅳ requiring TIPS were simultaneously implanted with 125Ⅰseed strand. Tumor thrombus was controlled with 125I seed implantation brachytherapy to keep the TIPS pathway unobstructed, reduce the portal vein pressure, and observe the changes in the cause of death of the patients. During the same period, 30 cases without TIPS and seed strand implantation were used as controls. Data between groups were compared using t-test, Chi-Squared test or Fisher's exact test. Results: TIPS combined with 125Ⅰ seed strand implantation was safe in patients with diffuse hepatocellular carcinoma combined with type III/IV portal vein tumor thrombus, and 92.0% (23/25) of the patients maintained unobstructed TIPS pathway. Compared with the control group, patients in the treatment group died of fewer lead-related complications, and most died from chronic liver failure (84.0% vs. 56.7%, χ2 = 4.771, P=0.029). The incidence of upper gastrointestinal bleeding was significantly decreased (12.0% vs. 46.7%, χ2 =7.674, P=0.006) and ascites severity was significantly improved (mild 40.0% vs. 16.7%, moderate 52.0% vs. 20.0%, severe 8.0% vs. 46.7%, χ2 =13.246 , P=0.001). Conclusions: TIPS combined with 125Ⅰ seed strand implantation is safe and feasible in patients with diffuse intrahepatic tumor combined with tumor thrombus type Ⅲ/Ⅳ. Moreover, it can effectively keep the shunt patency and reduce portal vein pressure, thereby reducing the incidence of upper gastrointestinal bleeding and improving the degree of ascites. TIPS combined with 125Ⅰ seed strand implantation may be used as a standard treatment modality for patients requiring TIPS therapy combined with tumor thrombus type Ⅲ/Ⅳ.

Abstract
Rock bream (Oplegnathus fasciatus) is a valuable commercial marine teleost species, which exhibits sexual dimorphism in growth performance. However, the absence of a rapid and cost-effective sex identification method based on sex-specific genetic marker has impeded study on sex determination mechanisms and breeding applications. In the present study, we firstly developed the PCR method for identifying potential sex-specific sequences in Oplegnathus fasciatus with the next-generation sequencing. Sex-specific genomic regions/loci for sex determination were discovered on Chr2 and Chr6 by genome-wide association analysis, sequencing depth, and heterozygosity comparison between females and males. Candidate sex-determining genes (CCDC63, ITR, WNT4) were furtherly detected in transcriptome data of testes and ovaries. Taken together, a male-specific 34-bp deletion on the Chr2 was identified and developed into molecular marker of sex for O. fasciatus. After validation in individuals with known phenotypic sexes, the accuracy was 100%. This study gives an insight into the mechanism of sex determination in O. fasciatus, and the gender marker is crucial both for future genomic research and for development of efficient and sustainable aquaculture practice.

Abstract
The Rock Bream (Oplegnathus fasciatus) is an economically important rocky reef fish of the Northwest Pacific Ocean. In recent years, it has been cultivated as an important edible fish in coastal areas of China. Despite its economic importance, genome-wide adaptions of domesticated O. fasciatus are largely unknown. Here we report a chromosome-level reference genome of female O. fasciatus (from the southern population in the subtropical region) using the PacBio single molecule sequencing technique (SMRT) and High-through chromosome conformation capture (Hi-C) technologies. The genome was assembled into 120 contigs with a total length of 732.95 Mb and a contig N50 length of 27.33 Mb. After chromosome-level scaffolding, 24 chromosomes with a total length of 723.22 Mb were constructed. Moreover, a total of 27,015 protein-coding genes and 5,880 ncRNAs were annotated in the reference genome. This reference genome of O. fasciatus will provide an important resource not only for basic ecological and population genetic studies but also for dissect artificial selection mechanisms in marine aquaculture.

Abstract
Large yellow croaker is an important marine culture species in China. Recently, the large yellow croaker industry is threatened by various disease problems, especially for the white spot disease, which is caused by parasite Cryptocaryon irritans. In the current study, we conducted a genome-wide association study (GWAS) for C. irritans resistance in two large yellow croaker populations (n = 264 and n = 480, respectively). We identified 15 QTL with explained genetic variance ranging from 1 to 8% in the two populations. One QTL on chromosome 23 was shared by the two populations, and three QTL had been reported in the previous study. We identified a lot of biological pathways associated with C. irritans resistance, such as hormone transport, response to bacterium, apoptotic process, acute inflammatory response to antigenic stimulus, and NF-kappa B signaling pathway. The genes casp8 and traf6 involved in regulatory network for apoptosis and inflammation were identified to be candidate genes for C. irritans resistance. Our results showed the complex polygenic architecture of resistance of large yellow croaker against C. irritans. These results would be helpful for the researches of the molecular mechanism of C. irritans resistance and genome-assisted breeding of large yellow croaker.

Abstract
Rock Bream (Oplegnathus fasciatus) is an important aquaculture species for offshore cage aquaculture and fish stocking of marine ranching in East Asia. Genomic selection has the potential to expedite genetic gain for the key target traits of a breeding program, but has not yet been evaluated in Oplegnathus. The purposes of the present study were to explore the performance of genomic selection to improve breeding value accuracy through real data analyses using six statistical models and to carry out genome‐wide association studies (GWAS) to dissect the genetic architecture of economically vital growth‐related traits (body weight, total length, and body depth) in the O. fasciatus population. After quality control, genotypes for 16,162 SNPs were acquired for 455 fish. Heritability was estimated to be moderate for the three traits (0.38 for BW, 0.33 for TL, and 0.24 for BD), and results of GWAS indicated that the underlying genetic architecture was polygenic. Six statistic models (GBLUP, BayesA, BayesB, BayesC, Bayesian Ridge‐Regression, and Bayesian LASSO) showed similar performance for the predictability of genomic estimated breeding value (GEBV). The low SNP density (around 1 K selected SNP based on GWAS) is sufficient for accurate prediction on the breeding value for the three growth‐related traits in the current studied population, which will provide a good compromise between genotyping costs and predictability in such standard breeding populations advanced. These consequences illustrate that the employment of genomic selection in O. fasciatus breeding could provide advantages for the selection of breeding candidates to facilitate complex economic growth traits.

Abstract
Larimichthys crocea is one of the traditional marine culture fishes in China, widely distributed in South China Sea, East Sea, and southern Yellow Sea. Sex dimorphism is evident in this species that females present a substantial growth strength than males, suggesting breeding females could obtain more economic benefits in L. crocea aquaculture industry. With the continuous expansion of aquaculture industry, both identifying sex-associated genome region and understanding the genetic basis underlying gonad differentiation and development matter to not only sex control aquaculture but also breeding industry. Thus, genome-wide association analysis (GWAS) of sex determination was conducted with a random breeding population of 905 individuals (including 463 females and 442 males) by ddRAD sequencing. For sex determination, 21 significant single nucleotide polymorphisms (SNPs) in chromosome (Chr) 22 were identified. Surrounding these SNPs, we founded 14 candidate genes, including dmrt1, dmrt3, and piwil2, fam102a, and odf2. The sex-associated region was narrowed down further to 2.4 Mb on Chr22 through Fst scanning and insertion-deletion (InDel) analysis. Besides, 3 SNPs in the supposed sex-determining region on Chr22 were identified as highly associated with gonad differentiation through GWAS on gonadosomatic index (GSI) in 350 males and 231 females. Because of the significant difference of GSI between females and males of L. crocea, GWAS on GSI of different genders was also conducted independently. Finally, we identified a SNP in Chr18 showing genome-wide significant association with male GSI (MGSI) and three genes axl, cyp2a10, and cyp2g1 involved in the gonadal development regulation process of aromatase. Overall, this study explored the genetic basis of sex determination mechanism and provided novel insights into gonad differentiation and development, offering solid genetic support for sex control breeding, marker-assisted selection, and marine resources conservation.

Abstract
Large-scale transcription studies have revealed numerous lncRNAs (long non-coding RNAs). lncRNAs have been proposed to participate in the regulation of a diverse range of biological processes, including transcriptional regulation. Although lncRNAs have attracted increasing attention, the studies in large yellow croaker (Larimichthys crocea) are still rare, and they lack systematic analysis. In this study, 101 RNA-seq datasets varied in ages, sexes, and tissues were retrieved from the NCBI database to generate a comprehensive catalog of large yellow croaker transcriptome database. A set of 14,599 high-confidence lncRNAs from 13,673 loci were identified and characterized. Furthermore, RNA-seq datasets obtained from the infection of C. irritans were employed to investigate the differential expression pattern of lncRNAs and analyze potential biological functions. A total of 77 differentially expressed lncRNAs targeting to 567 protein-coding genes were identified by using expression analysis. Several immune genes, including TLR5, CD2AP, and MMP9, were highlighted. With GO enrichment and KEGG pathway analysis, the immune-related terms or pathways were enriched. This study created a comprehensive dataset of lncRNAs for large yellow croaker, which would be helpful for the researches of functional roles of lncRNAs in large yellow croaker.

Abstract
High-density single-nucleotide polymorphism (SNP) genotyping array is an essential tool for genetic analyses of animals and plants. Large yellow croaker (Larimichthys crocea) is one of the most commercially important marine fish species in China. Although plenty of SNPs have been identified in large yellow croaker, no high-throughput genotyping array is available. In this study, a high-throughput SNP array named NingXin-I with 600K SNPs was developed and evaluated. A set of 82 large yellow croakers were collected from different locations of China and re-sequenced. A total of 9.34M SNPs were identified by mapping sequence reads to the large yellow croaker reference genome. About 1.98M candidate SNPs were selected for further analyses by using criteria such as SNP quality score and conversion performance in the final array. Finally, 579.5K SNPs evenly distributed across the large yellow croaker genome with an average spacing of 1.19 kb were proceeded to array production. The performance of NingXin-I array was evaluated in 96 large yellow croaker individuals from five populations, and 83.38% SNPs on the array were polymorphic sites. A further test of the NingXin-I array in five closely related species in Sciaenidae identified 26.68–56.23% polymorphic SNP rate across species. A phylogenetic tree inferred by using the genotype data generated by NingXin-I confirmed the phylogenetic distance of the species in Sciaenidae. The performance of NingXin-I in large yellow croaker and the other species in Sciaenidae suggested high accuracy and broad application. The NingXin-I array should be valuable for quantitative genetic studies, such as genome-wide association studies (GWASs), high-density linkage map construction, haplotype analysis, and genome-based selection.

Abstract
Large yellow croaker (Larimichthys crocea) is one of the most important cultured marine fish on the southeast coast of China. Its body shape is important for the aquaculture industry since it affects the behavior such as swimming, ingesting, and evading, as well as customer preference. Due to the greater consumer demand of small head, slender body large yellow croaker, selecting and breeding of slender individuals with the assistance of genetic markers will benefit the industry quickly. In this study, several traits were employed to represent body shape, including body depth/body length (BD/BL), body thickness/body length (BT/BL), caudal peduncle depth/caudal peduncle length (CPDLR), tail length/body length (TL/BL), and body area/head area (BA/HA). Genome-wide association study was conducted with a panmictic population of 280 individuals to identify SNP and genes potentially associated with body shape. A set of 20 SNPs on 12 chromosomes were identified to be significantly associated with body shape-related traits. Besides, 5 SNPs were identified to be suggestive associated with CPDLR and BT/BL. Surrounding these SNPs, we found some body shape-related candidate genes, including fabp1, acrv1, bcor, mstn, bambi, and neo1, which involved in lipid metabolism, TGF-β signaling, and BMP pathway and other important regulatory pathways. These results will be useful for the understanding of the genetic basis of body shape formation and helpful for body shape controlling of large yellow croaker by using marker-assisted selection.

Abstract
The whole mitochondrial genome ofLateolabrax maculatus(Cuvier, 1828) was used to investigate the reasons for the observed patterns of genetic differentiation among 12 populations in northern and southern China. The haplotype diversity and nucleotide diversity ofL. maculatuswere 0.998 and 0.00169, respectively. Pairwise FSTvalues between populations ranged from 0.001 to 0.429, correlating positively with geographic distance. Genetic structure analysis and haplotype network analysis indicated that these populations were split into two groups, in agreement with geographic segregation and environment. Tajima’s D values, Fu’s Fs tests and Bayesian skyline plot (BSP) indicated that a demographic expansion event may have occurred in the history ofL. maculatus. Through selection pressure analysis, we found evidence of significant negative selection at the ATP6, ND3, Cytb, COX3, COX2 and COX1 genes. In our hypotheses, this study implied that demographic events and selection of local environmental conditions, including temperature, are responsible for population divergence. These findings are a step forward toward the understanding of the genetic basis of differentiation and adaptation, as well as conservation ofL. maculatus.

Abstract
Large yellow croaker (Larimichthys crocea) is one of the most important mariculture fish in China. In the past decades, cryptocaryonosis caused by Cryptocryon irritans has led to huge economic losses, posing great threat to the healthy and sustainable development of L. crocea mariculture industry. As the largest immunologically active mucosal organ in fish, skin provides the first defense line against external pathogens. To better understand the gene expression dynamics, the large yellow croakers were artificially infected with C. irritans and their skin tissues were collected at 0 h, 24 h, 48 h, 72 h and 96 h post infection. The total RNA in the skin tissues were extracted and the transcriptome were sequenced. After sequencing, a total of 1,131, 311, 140 million high quality RNA-seq reads were collected. A set of 215, 473, 968, 1055 differentially expressed genes were identified at 24 h, 48 h, 72 h and 96 h post infection respectively. Further analysis clustered these DEGs into six profiles and 75 hub genes for six profiles were identified. Among these hub genes, 18 immune related genes including TLR5, TOPK, NFKBIZ, MAPK14A were identified post C. irritans infection. Cytokine-cytokine receptor interaction was the only pathway that significantly enriched at four timepoints post infection. This study provides an in-depth understanding of skin transcriptome variance of large yellow croaker after C. irritans infection, which would be helpful for further understanding of the molecular mechanism of L. crocea in response to C. irritans infection.

Abstract
Large yellow croaker (Larimichthys crocea) is an economically important marine fish species of China. Due to overfishing and marine pollution, the wild stocks of this croaker have collapsed in the past decades. Meanwhile, the cultured croaker is facing the difficulties of reduced genetic diversity and low growth rate. To explore the molecular markers related to the growth traits of croaker and providing the related SNPs for the marker-assisted selection, we used double-digest restriction-site associated DNA (ddRAD) sequencing to dissect the genetic bases of growth traits in a cultured population and identify the SNPs that associated with important growth traits by GWAS. A total of 220 individuals were genotyped by ddRAD sequencing. After quality control, 27,227 SNPs were identified in 220 samples and used for GWAS analysis. We identified 13 genome-wide significant associated SNPs of growth traits on 8 chromosomes, and the beta P of these SNPs ranged from 0.01 to 0.86. Through the definition of candidate regions and gene annotation, candidate genes related to growth were identified, including important regulators such as fgf18, fgf1, nr3c1, cyp8b1, fabp2, cyp2r1, ppara, and ccm2l. We also identified SNPs and candidate genes that significantly associated with body shape, including bmp7, col1a1, col11a2, and col18a1, which are also economically important traits for large yellow croaker aquaculture. The results provided insights into the genetic basis of growth and body shape in large yellow croaker population and would provide reliable genetic markers for molecular marker-assisted selection in the future. Meanwhile, the result established a basis for our subsequent fine mapping and related gene study.

Abstract
Larimichthys crocea is an endemic marine fish in East Asia that belongs to Sciaenidae in Perciformes. L. crocea has now been recognized as an "iconic" marine fish species in China because not only is it a popular food fish in China, it is a representative victim of overfishing and still provides high value fish products supported by the modern large-scale mariculture industry. Here, we report a chromosome-level reference genome of L. crocea generated by employing the PacBio single molecule sequencing technique (SMRT) and high-throughput chromosome conformation capture (Hi-C) technologies. The genome sequences were assembled into 1,591 contigs with a total length of 723.86 Mb and a contig N50 length of 2.83 Mb. After chromosome-level scaffolding, 24 scaffolds were constructed with a total length of 668.67 Mb (92.48% of the total length). Genome annotation identified 23,657 protein-coding genes and 7262 ncRNAs. This highly accurate, chromosome-level reference genome of L. crocea provides an essential genome resource to support the development of genome-scale selective breeding and restocking strategies of L. crocea.

Abstract
The large yellow croaker (Larimichthys crocea) is the most economically important marine cage-farming fish in China in the past decade. However, the sustainable development of large yellow croaker aquaculture has been severely hampered by several diseases, of which, the white spot disease caused by ciliate protozoan parasite Cryptocaryon irritans ranks the most damaging disease in large yellow croaker cage farms. To better understand the genetic basis of parasite infection and disease resistance to C. irritans, it is vital to map the traits and localize the underlying candidate genes in L. crocea genome. Here, we constructed a high-density genetic linkage map using double-digest restriction-site associated DNA (ddRAD)-based high-throughput SNP genotyping data of a F1 mapping family, which had been challenged with C. irritans for resistant trait measure. A total of 5261 SNPs was grouped and oriented into 24 linkage groups (LGs), representing 24 chromosomes of L. crocea. The total genetic map length was 1885.67 cM with an average inter-locus distance of 0.36 cM. Quantitative trait loci (QTL) mapping identified seven significant QTLs in four LGs linked to C. irritans disease resistance. Candidate genes underlying disease resistance were identified from the reference genome, including ifnar1, ifngr2, ikbke, and CD112. Comparative genomic analysis between large yellow croaker and the four closely related species revealed high evolutionary conservation of chromosomes, though inter-chromosomal rearrangements do exist. Especially, the croaker genome structure was closer to the medaka genome than stickleback, indicating that the croaker genome might retain the teleost ancestral genome structure. The high-density genetic linkage map provides an important tool and resource for fine mapping, comparative genome analysis, and molecular selective breeding of large yellow croaker.

Abstract
Objective: To investigate the inducing effect and mechanism of semimature dendritic cell (smDCs) on transplantation tolerance of hepatocytes differentiated from mouse embryonic stem cells (ESCs), and to study the connections between smDCs and regulatory dendritic cells (regDCs). Methods: ESCs of 129 mouse labelled green fluorescent protein (GFP) were induced to hepatocytes by using previous methods. Meanwhile, bone marrow mononuclear cells of 129 mouse were induced to smDCs and regDCs. Moreover, the hepatocytes differentiated from 129 mouse ESCs were transplanted into liver of BALB/c mouse 3 days after infusing smDCs and regDCs suspension of 129 mouse into BALB/c mouse by tail vein respectively. After that, the growth status and survival time of transplanted cells in the recipient and infiltration of lymphocytes in transplant sites were observed. Furthermore, Foxp3 expression of peripheral blood CD4+ T cells was also tested. Results: In the control group, the transplanted cells in liver of BALB/c mouse survived only about 1 week. In contrast, the transplanted cells of smDC groups and regDCs groups survived about 4 weeks and the transplant sites of smDC groups also had less CD3(+) T cells. The morphology of smDCs were similar with regDCs. The expression of MHC-Ⅱ, CD40, CD80 and CD86 on smDCs and regDCs were moderate. Moreover, the Foxp3 expression of peripheral blood CD4+ T cells in smDC groups was higher than that in the control groups, from 1.11% up to 5.38%. The Foxp3 expression in regDC groups rose to 3.87%. Conclusion: The smDCs could induce transplantation tolerance of hepatocytes differentiated from 129 mouse ESCs in the recipient. The mechanism was associated with high level of Foxp3(+) Tregs, which could be increased by means of smDCs appropriate expression of MHC-Ⅱ, CD40, CD80 and CD86. The smDCs and regDCs were the same type of tolerance dendritic cells.

Abstract
Background Cryptocaryon irritans is an obligate parasitic ciliate protozoan that can infect various commercially important mariculture fish species and cause high lethality and economic loss. Current methods of controlling this parasite with chemicals or antibiotics are widely considered to be environmentally harmful. Piscidins with broad spectrum antibacterial, antifungal and antiviral activities were found to have potent activity against C. irritans. Little, however, has been understood about the killing mechanisms of piscidins in parasites. Results In total, 57.12, 50.44, 55.86 and 47.87 million raw reads were generated from untreated theront and trophont, and piscidin (Lc-pis) treated theront and trophont libraries, respectively. After de novo assembly, 966,609 unigenes were generated with an average length of 420 bp: among these, 618,629 unigenes showed identity with sequences in one or more databases, with some showing to be significantly manipulated by Lc-pis treatment. The species classification showed that more than 25.8% unigenes from trophonts were homologous to the large yellow croaker (Larimichthys crocea) and less than 3.8% unigenes from theronts were matched. The homologous unigenes demonstrated that the tissue from host could exist in trophonts and might be transported to parasite via vesicular transports. Our analysis showed that regulatory transcripts were involved in vesicular trafficking. Among transcripts induced by Lc-pis, most genes up-regulated in treated and untreated theronts were involved in cell migration and apoptosis related pathways. Few transcripts were found to be down-regulated in treated and untreated trophonts related to cell structure and migration after treatment. Conclusions This is the first transcriptome analysis of C. irritans exposed to Lc-pis, which enhanced the genomic resources and provided novel insights into molecular mechanisms of ciliates treated by cationic antimicrobial peptide. Our comprehensive transcriptome analysis can facilitate the identification of potential drug targets and vaccines candidates for controlling this devastating fish pathogen.

Abstract
The enteric nervous system (ENS) is recognized as a second brain because of its complexity and its largely autonomic control of bowel function. Recent progress in studying the interactions between the ENS and the central nervous system (CNS) has implicated alterations of the gut/brain axis as a possible mechanism in the pathophysiology of autism spectrum disorders (ASDs), Parkinson's disease (PD) and other human CNS disorders, whereas the underlying mechanisms are largely unknown because of the lack of good model systems. Human induced pluripotent stem cells (hiPSCs) have the ability to proliferate indefinitely and differentiate into cells of all three germ layers, thus making iPSCs an ideal source of cells for disease modelling and cell therapy. Here, hiPSCs were induced to differentiate into neural crest stem cells (NCSCs) efficiently. When co-cultured with smooth muscle layers of ganglionic gut tissue, the NCSCs differentiated into different subtypes of mature enteric-like neurons expressing nitric oxide synthase (nNOS), vasoactive intestinal polypeptide (VIP), choline acetyltransferase (ChAT) or calretinin with typical electrophysiological characteristics of functional neurons. Furthermore, when they were transplanted into aneural or aganglionic chick, mouse or human gut tissues in ovo, in vitro or in vivo, hiPSC-derived NCSCs showed extensive migration and neural differentiation capacity, generating neurons and glial cells that expressed phenotypic markers characteristic of the enteric nervous system. Our results indicate that enteric NCSCs derived from hiPSCs supply a powerful tool for studying the pathogenesis of gastrointestinal disorders and brain/gut dysfunction and represent a potentially ideal cell source for enteric neural transplantation treatments.

Abstract
UNLABELLED Essentials (NZWxBXSB)F1 male mice develop antibodies beta2-glycoprotein I (β2GPI) and hypertension. A1-A1 is a soluble analogue of ApoE receptor 2 with a high affinity for β2GPI/antibody complexes. A1-A1 improved blood pressure and arterial elastance in (NZWxBXSB)F1 male mice. A1-A1 had no adverse effects on the hemodynamics of healthy mice. SUMMARY Background Antiphospholipid syndrome (APS) is diagnosed based on the presence of antiphospholipid antibodies and clinical thrombosis or fetal loss during pregnancy. Lupus-prone (NZWxBXSB)F1 male mice are the mouse model of spontaneous APS. They develop anti-β2GPI antibodies, microinfarcts and hypertension. ApoER2 is a receptor that contributes to anti-β2GPI-dependent thrombosis in APS by down-regulating endothelial nitric oxide synthase activation. Objectives A1-A1 is a small protein constructed from two identical ligand-binding modules from ApoER2, containing the binding site for β2GPI. We studied how treatment with A1-A1 affects the development of hypertension in (NZWxBXSB)F1 male mice. Methods We treated (NZWxBXSB)F1 male mice with A1-A1 for up to 4 weeks and examined changes in hemodynamics by left ventricular pressure-volume loop measurements. Results We observed improvements in blood pressure in the A1-A1 treated mice. A1-A1 prevented the deterioration of arterial elastance by decreasing systemic resistance and improving vessel compliance. We did not detect any adverse effects of the treatment in either male mice or in apparently healthy female (NZWxBXSB)F1 mice. Conclusions We demonstrated that A1-A1, which is a soluble analog of ApoER2 that binds pathological β2GPI/anti-β2GPI complexes, has a positive impact on hemodynamics in lupus-prone mice with spontaneous anti-β2GPI antibodies and hypertension.

Abstract
To clarify the effects of a Cryptocaryon irritans infection on the stress, antioxidant and mucosal immune response of the large yellow croaker Pseudosciaena crocea, this study utilized C. irritans at dose of 12,000 (group I); 24,000 (group II); and 36,000 (group III) theronts/fish to infect large yellow croaker weighing 100 ± 10 g. The food intake, survival and relative infection intensity (RII); levels of reactive oxygen species (ROS), malondialdehyde (MDA) and vitamin C (VC), activities of super oxide dismutase (SOD) and catalase (CAT) in liver; variation patterns of lysozyme (LZM), alkaline phosphatase (AKP), complement component 3 (C3) and immunoglobulin M (IgM) levels in the body surface mucus at different time points after infection were compared. These results showed that with the increase of the infection dose and the passage of time, the food intake and survival of the fish gradually decreased. The final survival of the control group (0 theronts/fish), group I, group II, and group III was 100, 100, 96.67 ± 5.77, and 48.33 ± 7.64. Group I, II, and III stopped feeding respectively on the third, third and second days after infection. RII increased significantly with increased infection dose. The RII of the control group, group I, group II, and group III was 0, 0.73 ± 0.06, 1.30 ± 0.26, and 1.84 ± 0.02. With the infection dose increased, ROS contents showed an overall upward trend; MDA contents of the group I, group II and group III did not show significant changes at any timepoint compared with the control group; Activities of SOD and CAT and the overall VC levels in the liver of P. crocea dropped; LZM activity showed an overall upward trend; AKP activity increased first then dropped at each timepoint with its highest level appearing at group II; Complement C3 and IgM levels in body surface mucus were significantly increased. In conclusion, P. crocea has a strong ability to resist oxidative stress caused by the infection of C. irritans. The body surface mucus of P. crocea contains high levels of immune factors, which presented a rapid and significant response to the infection of C. irritans.

Abstract
Nestin is widely expressed in numerous tumors and has become a diagnostic and prognostic indicator. However, the exact mechanism by which nestin contributes to tumor malignancy remains poorly understood. Here, we found marked upregulation of nestin expression in highly proliferative and invasive gastrointestinal stromal tumor (GIST) specimens. Nestin knockdown in GIST cells reduced the proliferative and invasive activity owing to a decrease of mitochondrial intracellular reactive oxygen species (ROS) generation. Furthermore, nestin was co-localized with mitochondria, and knockdown of nestin increased mitochondrial elongation and influenced the mitochondrial function, including oxygen consumption rates, ATP generation and mitochondrial membrane potential and so on. In exploring the underlying mechanism, we demonstrated nestin knockdown inhibited the mitochondrial recruitment of Dynamin-related protein1 and induced the change of mitochondrial dynamics. Thus, nestin may have an important role in GIST malignancy by regulating mitochondrial dynamics and altering intracellular ROS levels. The findings provide new clues to reveal mechanisms by which nestin mediates the proliferation and invasion of GISTs.

Abstract
OBJECTIVES Acetazolamide has been the most commonly used treatment for hypokalemic periodic paralysis since 1968. However, its mechanism of efficacy is not fully understood, and it is not known whether therapy response relates to genotype. We undertook a clinical and genetic study to evaluate the response rate of patients treated with acetazolamide and to investigate possible correlations between response and genotype. METHODS We identified a total of 74 genotyped patients for this study. These included patients who were referred over a 15-year period to the only U.K. referral center or to a Chinese center and who underwent extensive clinical evaluation. For all genotyped patients, the response to acetazolamide therapy in terms of attack frequency and severity was documented. Direct DNA sequencing of CACNA1S and SCN4A was performed. RESULTS Only 46% of the total patient cohort (34 of 74) reported benefit from acetazolamide. There was a greater chance of benefit in patients with mutations in CACNA1S (31 responded of 55 total) than in those with mutations in SCN4A (3 responded of 19 total). Patients with mutations that resulted in amino acids being substituted by glycine in either gene were the least likely to report benefit. CONCLUSIONS This retrospective study indicates that only approximately 50% of genotyped patients with hypokalemic periodic paralysis respond to acetazolamide. We found evidence supporting a relationship between genotype and treatment response. Prospective randomized controlled trials are required to further evaluate this relationship. Development of alternative therapies is required.

Abstract
This study evaluated the plastic changes of c-jun and c-fos in the right sixth lumbar dorsal root ganglion (L6 DRG), Rexed's lamina II in representative spinal segments L3, L5, and L6 and in the nucleus dorsalis (ND) at L3 segments after electro-acupuncture (EA) in cats subjected to removal of L1-L5 and L7-S2 DRG. Following dorsal root ganglionectomy, there was a significant increase in the density of c-jun immunoreactivity in the neurons and glia in spinal lamina II and in the ND; there was also marked elevation in the expression of c-fos in ND. In both cases there was no change in the c-jun and c-fos immunoreactivity in the DRG. After EA in the operated animals, there was an up-regulation in the expression of c-jun in the L6 DRG and the associated spinal lamina II; however, increased c-fos expression was detected only in the L6 DRG. Western blot and RT-PCR were also performed to quantitatively explore the mRNA and protein expression changes in the spinal dorsal horn and associated DRG. Following partial deafferentation, there was a significant increase in the protein level of both c-jun and c-fos in the dorsal horn, while, in both cases there was no change in c-jun and c-fos protein and mRNA in the DRG. After EA in the operated animals, both c-jun protein and its mRNA in the L6 DRG as well as the associated dorsal horn of L6 spinal segment were upregulated, but increased c-fos protein and its mRNA was observed only in the L6 DRG. These findings suggested that c-jun and c-fos might be related to the acupuncture promoted spinal cord plasticity as reported previously.

Abstract
Suppression of cardiac voltage-gated Na(+) currents is probably one of the important factors for the cardioprotective effects of the n-3 polyunsaturated fatty acids (PUFAs) against lethal arrhythmias. The alpha subunit of the human cardiac Na(+) channel (hH1(alpha)) and its mutants were expressed in human embryonic kidney (HEK293t) cells. The effects of single amino acid point mutations on fatty acid-induced inhibition of the hH1(alpha) Na(+) current (I(Na)) were assessed. Eicosapentaenoic acid (EPA, C20:5n-3) significantly reduced I(Na) in HEK293t cells expressing the wild type, Y1767K, and F1760K of hH1(alpha) Na(+) channels. The inhibition was voltage and concentration-dependent with a significant hyperpolarizing shift of the steady state of I(Na). In contrast, the mutant N406K was significantly less sensitive to the inhibitory effect of EPA. The values of the shift at 1, 5, and 10 microM EPA were significantly smaller for N406K than for the wild type. Coexpression of the beta(1) subunit and N406K further decreased the inhibitory effects of EPA on I(Na) in HEK293t cells. In addition, EPA produced a smaller hyperpolarizing shift of the V(1/2) of the steady-state inactivation in HEK293t cells coexpressing the beta(1) subunit and N406K. These results demonstrate that substitution of asparagine with lysine at the site of 406 in the domain-1-segment-6 region (D1-S6) significantly decreased the inhibitory effect of PUFAs on I(Na), and coexpression with beta(1) decreased this effect even more. Therefore, asparagine at the 406 site in hH1(alpha) may be important for the inhibition by the PUFAs of cardiac voltage-gated Na(+) currents, which play a significant role in the antiarrhythmic actions of PUFAs.

Abstract
Dietary polyunsaturated fatty acids (PUFAs) prevent ischemia-induced fatal cardiac arrhythmias in animals and probably in humans. This action results from inhibition of ion currents for Na+, Ca2+, and possibly other ions. To extend understanding of this protection we are seeking a possible binding site for the PUFAs on the alpha-subunit of the human cardiac Na+ channel, hH1alpha, transiently expressed in HEK293t cells. Three mutated single amino acid substitutions with lysine were made in the alpha-subunit at Domain 4-Segment 6 (D4-S6) for F1760, Y1767 and at D1-S6 for N406. These are in the putative sites of binding of local anesthetics and batrachotoxin, respectively. The mutants F1760K, Y1767K, and N406K, separately and to different extents, affected the current density, the steady-state inactivation potential, accelerated inactivation, delayed recovery from inactivation, and affected voltage-dependent block, but did not affect activation of the hH1alpha. It is essential to learn that single point mutations in D1-S6 and D4-S6 alone significantly modify the kinetics of human cardiac hH1alpha Na+ currents. The effects of PUFAs on these mutant channels will be the subject of subsequent reports.

Abstract
We have recently observed that protein kinase C (PKC) was involved in the regulation of the accumulation of mRNAs of the AP-1 components in cultured Abelson-transformed murine fetal-liver-derived mast cells stimulated by exocytotic stimuli. Here we analyzed the probable regulatory effect of PKC on the synthesis and DNA-binding activity of AP-1 complexes in immunologic stimulated mast cells. In this study we used the interleukin-3--dependent murine fetal-liver--derived mast cells that were not transformed by the Abelson oncogene. Study of PKC-depleted cells showed PKC dependency of c-fos mRNA accumulation and protein expression in IgE-Ag stimulated cells. In contrast, the c-jun mRNA accumulation was unaffected by PKC depletion, whereas its protein expression was dependent on this enzymatic activity. This suggests the involvement of PKC in the regulation of translation of c-Jun, a level of c-Jun regulation that was not previously described. The amount of AP-1 DNA-bound complex was also lowered in PKC-depleted cells. Therefore, PKC plays an important regulatory role in different stages of the signal transduction pathway because of IgE-Ag stimulation. Surprisingly, we have observed that although the amount of total synthesized c-Fos began to increase 15 minutes after immunologic stimulation, the amount of c-Fos associated with Juns did not increase, even after 45 minutes. This association was not affected by PKC. Using a Fos-interacting protein (FIP)-cDNA probe, an expression of 2.9 kb mRNA was detected in these cells. Furthermore, immunologic stimulation caused an increase in the amount of a Fos-containing protein complex that bound to an FIP-binding DNA oligonucleotide. Therefore, we propose that this protein complex that contains most of the immunologically induced c-Fos has an important role in IgE-Ag-stimulated signal transduction.
