Abstract
Aeromonas hydrophila is an opportunistic pathogen that frequently leads to significant mortality in various commercially cultured aquatic species. Bacteriophages offer an alternative strategy for pathogens elimination. In this study, we isolated, identified, and characterized a novel temperate A. hydrophila phage, designated as P05B. The bacteriophage P05B is a myovirus based on its morphological features, and possesses the capability to lyse A. hydrophila strains isolated from shrimp. The optimal multiplicity of infection (MOI), adsorption rate, latent period, and burst size for phage P05B were determined to be 0.001, 91.7 %, 20 min, and 483 PFU/cell, respectively. Phage P05B displayed stability across a range of temperatures (28-50 °C) and pH values (4.0-10.0). Sequence analysis unveiled that the genome of phage P05B comprises 32,302 base pairs with an average G + C content of 59.4 %. A total of 40 open reading frames (ORF) were encoded within the phage P05B genome. The comparative genomic analyses clearly implied that P05B might represent a novel species of the genus Bielevirus under Peduoviridae family. A phylogenetic tree was reconstructed, demonstrating that P05B shares a close evolutionary relationship with other Aeromonas and Aeromonas phages. In conclusion, this study increased our knowledge about a new temperate phage of A. hydrophila with strong lytic ability.

Abstract
Trionyx sinensis Hemorrhagic Syndrome Virus (TSHSV), the first aquatic arterivirus identified in China, causes severe mortality to T. sinensis. In this study, we sought to determine the functions of T. sinensis mRNAs and non-coding RNAs (ncRNAs) that were differentially expressed (DE) over different periods of TSHSV infection of T. sinensis lung. We used RT-qPCR to validate the sequencing results of select RNAs, confirming their reliable and referable nature. Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were used to predict multiple biological functions and signaling pathways in various comparison groups (1-day versus mock, 3-day versus 1-day, and 5-day versus 3-day). Multiple types of differentially expressed RNA, including mRNA, lncRNA, circRNA, and miRNA, were associated with cardiac dysfunction, coagulation abnormalities, and arachidonic acid metabolism at day 1. Pre-inflammatory cytokines and inflammatory factors such as PLA2G4A, cPLA2, γ-GGT1, TNFRSF14, TCP11L2, PTER CYP2J2 and LTC4S, were noticeably regulated at the same time. On day 3, multiple GO terms and KEGG pathways were implicated, including those related to virus defense, apoptosis, pyroptosis, and inflammatory response. Notably, key genes such as RSAD2, TRIM39, STAT4, CASP1, CASP14, MYD88, CXCL3, CARD11, ZBP1, and ROBO4 exhibited significant regulation. The lncRNAs and circRNAs that targeted the genes involved in viral recognition (TLR5), apoptosis (CARD11), pyroptosis (ZBP1), inflammatory processes (NEK7, RASGRP4, and SELE) and angiogenesis (ROBO4) exhibited significant regulation. Significantly regulated miRNAs were primarily linked to genes involved in apoptosis (Let-7f-3p, miR-1260a, miR-455-3p), and inflammation (miR-146a, miR-125a, miR-17a, miR-301b, and miR-30a-3p). The findings could advance our understanding of the host immunological response to TSHSV and offer new ideas for developing effective strategies to prevent infection of T. sinensis.

Abstract
Sporotrichosis, a fungal infection caused by Sporothrix species, can greatly lead to chronic inflammation of the skin, mucosa, and lymphatic vessels and disseminate systemically sometimes, even threatening life. It is known that Sporothrix is distributed worldwide, while in China, most of the cases were reported in northeast China and parts of south China. Sporothrix globosa is the main source of infection, and other regions may lack relevant awareness and attention to the disease, making it a public health challenge in China. Thus, it is important to understand its epidemiology and public health risks to prevent and control the disease properly.

Abstract
Objective: To explore the correlation between blood glucose levels and the three factors of sarcopenia (muscle mass, strength and function) in older Chinese community dwellers. Methods: This is a retrospective study conducted by collecting the data of patients in Jiangsu Huaqiao Road Community Health Service Center from 2018 to 2019. Two hundred and fifty people aged 60 years or elder were selected. Among them, 101 were men and 149 were women. According to the American Diabetes Association diagnostic criteria for diabetes mellitus in 2018, they were divided into normal glucose tolerance (NGT) group, pre-diabetes group and diabetes group. The patients were assessed for sarcopenia as well. Results: Compared with those in the NGT group, muscle mass and upper limb muscle strength did not change in the diabetic group, but lower limb muscle strength and body function [walking speed, balance, short physical performance battery (SPPB)] decreased significantly in the diabetic group. Pearson correlation analyses showed that fasting plasma glucose(FPG) was negatively correlated with walking speed (r=-0.248, P=0.001), three-pose balance (r=-0.166, P=0.013) and SSPB (r=-0.213, P=0.001). Glycosylated hemoglobin A1c(HbA1c) was positively correlated with sitting and standing time (r=0.205, P=0.002), and negatively correlated with three-pose balance (r=-0.186, P=0.006) and SSPB (r=-0.154, P=0.024). Multiple regression analyses showed that FPG was negatively associated with walking speed (β=-0.125, P=0.005) and SPPB (β=-0.034, P=0.012), and that HbA1c was positively associated with sitting and standing time (β= 0.218, P =0.006) and negatively associated with three-pose balance (β=-0.143, P=0.012), and SPPB (β=-0.117, P =0.036). Conclusions: There is no significant correlation between blood glucose levels and muscle mass in the elderly; however, FPG is closely correlated with gait speed, and HbA1c is closely correlated with muscle strength of lower limbs and balance ability in the elderly.

Abstract
Abstract
Background
Standard scoring system for bleeding risk assessment has not been developed in patients with atrial fibrillation (AF) and acute coronary syndrome (ACS) or undergoing percutaneous coronary intervention (PCI). The study aims to evaluate the predictive value of the HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score in patients with AF and ACS/PCI who received both anticoagulant and antiplatelet therapy.
Methods
A total of 930 patients with AF and ACS/PCI receiving both anticoagulant and antiplatelet therapy were consecutively recruited and followed up for 1 year. The primary endpoint was defined according to the bleeding academic research consortium (BARC) criteria as major (BARC 3a, 3b, 3c, and 5) and any bleeding (BARC 2, 3a, 3b, 3c, and 5). The secondary endpoints included major or minor bleeding according to TIMI criteria. Univariate and multivariate logistic regression were performed to evaluate the association between bleeding risk scores and outcomes. Receiver operating characteristic (ROC) curves were constructed and c-statistics were calculated to evaluate the predictive performance of different bleeding risk scores.
Results
BARC class ≥2 bleedings occurred in 36 patients (3.9%), while BARC class ≥3 bleedings were seen in 134 patients (14.4%). The HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score were significantly associated with incidences of BARC class ≥2 and ≥3 bleedings during 1-year follow-up (all p<0.05). The ROC analysis showed that the predictive performance of the five bleeding risk scores for BARC class ≥3 bleedings were low-to-moderate [c-statistic: HASBLED 0.584 (0.552–0.616), ATRIA 0.624 (0.592–0.655), ORBIT 0.623 (0.591–0.654), PARIS 0.633 (0.601–0.664), PRECISEDAPT 0.616 (0.584–0.647)]. Multivariable logistic regression indicated that previous bleeding history and hemoglobin were independent predictors of BARC class ≥3 bleedings. Compared to the HAS-BLED score, the model constructed by previous bleeding history and hemoglobin displays a significant improvement in bleeding risk prediction (0.704 vs. 0.584, p=0.013).
Conclusions
In patients with AF and ACS/PCI receiving both anticoagulant and antiplatelet therapy, the HAS-BLED, ORBIT, ARTIA, PARIS, and PRECISE-DEAPT score displayed low-to-moderate performance for predicting BARC class ≥3 bleedings during 1-year follow-up. More accurate scoring systems for bleeding risk evaluation should be developed for these patients in the future.

Abstract
Abstract
Background
This study aimed to evaluate the association between plasma big endothelin-1 (ET-1) level and the severity of coronary artery disease assessed by the SYNTAX score (SS) in patient with non-ST segment-elevated myocardial infarction (NSTEMI).
Methods
A total of 766 patients with NSTEMI undergoing coronary angiography were recruited. Patients were divided into divided into three groups: low SS (SS ≤22), intermediate SS (23–32) and high SS group (SS >32). Spearman correlation, smooth curve fitting, logistic regression and Receiver operating characteristic (ROC) curve analysis were performed to evaluated the association between plasma big ET-1 level and the SS.
Results
There was a significant correlation between the big ET-1 and the SS (r=0.378, p<0.001). Smoothing curve indicated a positive correlation between plasma big ET-1 level and the SS, after adjustment for potential confounders. The ROC curve analysis showed that the area under the curve was 0.695 (0.661–0.727) and the optimal cutoff of plasma big ET-1 level were 0.35pmol/l, with a sensitivity of 68.9% and a specificity of 62.9%. Logistic regression showed that elevated big ET-1 was an independent predictor of intermediate-high SS in patients with NSTEMI, no matter entered as a continuous variable [OR (95% CI): 1.110 (1.053–1.170), p<0.001] or as a categorical variable [OR (95% CI): 2.873 (2.016–4.094), p<0.001]. The association between big ET-1 and intermediate-high SS was consistent across subgroups without significant interactions.
Conclusion
In patients presenting with NSTEMI, plasma big ET-1 level was significantly correlated with the SS. Elevated plasma big ET-1 level was an independent predictor for intermediate-high SS.

Abstract
Abstract
Objective
The Global Registry of Acute Coronary Events (GRACE) score is recommended for risk stratification for patients with ST-segment elevation myocardial infarction (STEMI) by clinical guidelines. Data about comorbidities were not incorporated in the GRACE score. This study aimed to evaluate the incremental predictive value of adding the CHA2DS2-VASc score to the GRACE score for in-hospital mortality in patients with STEMI.
Methods
7476 patients with STEMI were recruited and divided into five groups according to the CHA2DS2-VASc score (1, 2, 3, 4 and ≥5 points) at admission. The primary outcome was defined as in-hospital mortality, while the secondary outcomes were recurrent MI, stroke and major adverse cardiovascular events (MACE) during hospitalization. Univariate and multivariate logistic regression were performed to evaluate the association between the CHA2DS2-VASc score and outcomes. Incremental predictive performance of adding the CHA2DS2-VASc score to the GRACE score were evaluated through analysis of the receiver operating characteristic (ROC) curves, net reclassification improvement (NRI) and integrated discrimination improvement (IDI).
Results
With the increase of CHA2DS2-VASc score, patients with STEMI tended to have more comorbidities, receive less evidence-based treatments and carry worse in-hospital outcomes. Multivariate logistic regressions demonstrated that the CHA2DS2-VASc score was an independent predictor for in-hospital mortality [OR (95% CI): 1.320 (1.238–1.407), p<0.001], recurrent myocardial infarction [OR (95% CI): 1.233 (1.086–1.401), p=0.001], stroke [OR (95% CI): 1.433 (1.207–1.702), p<0.001] and MACE [OR (95% CI): 1.146 (1.088–1.207), p<0.001]. The c statistic value of combining the GRACE score with the CHA2DS2-VASc score was significantly higher than that of the GRACE score alone in predicting in-hospital mortality (0.784, 95% CI: 0.774–0.793 vs. 0.769, 95% CI: 0.760–0.779, z=4.180, p<0.001). The addition of the CHA2DS2-VASc score to the GRACE score resulted in significantly improved predictive performance for in-hospital mortality, with a NRI of 0.356 (95% CI: 0.280–0.432, p<0.001) and a IDI of 0.013 (95% CI: 0.009–0.018, p<0.001).
Conclusion
The CHA2DS2-VASc score was an independent predictor of in-hospital outcomes in patients with STEMI. Compared to the GRACE score alone, the addition of the CHA2DS2-VASc score to the GRACE score improved the predictive performance for in-hospital mortality in patients STEMI.

Abstract
Trionyx sinensis Hemorrhagic Syndrome Virus (TSHSV) is an arterivirus newly discovered in Chinese softshell turtles. Little is known about the effect of antibodies against the virus or the distribution of the virus in different organs of infected turtles. In this study, a partial protein of TSHSV-HP4 was produced using a prokaryotic expression system, and its polyclonal antibody was generated. The polyclonal antibody was confirmed by western blot and dot enzyme-linked immunosorbent assay (dot-ELISA). The distribution of TSHSV in different organs of T. sinensis was examined by immunohistochemistry (IHC) and the expression of immune-related genes was analyzed using quantitative real-time polymerase chain reaction (qRT-PCR). The results indicated that the recombinant TSHSV-HP4 protein was successfully expressed, and the generated polyclonal antibody showed specific binding to viral particles in the lung tissues of infected turtles. The IHC assay indicated that the virus was highly localized in various cells, including intestinal lymphocytes, enterocytes, kidney epithelial cells, spleen cells, lung macrophages, and cardiomyocytes. The qRT-PCR analysis revealed that TSHSV was detected in all organs tested, including the lungs, liver, kidneys, spleen, and heart. The numbers of viral mRNA copies in lung and heart tissues were significantly higher in the virus-antibody group than in the virus group. The interferon-stimulated genes (ISGs), myxovirus resistance protein 2 (MX2) and radical S-adenosyl methionine domain containing 2 (RSAD2) were highly upregulated in all groups of infected turtles. Antibody-dependent enhancement (ADE) seemed to occur after stimulation by the polyclonal antibody, because significantly greater expression of the two genes was detected in the virus-antibody group than in the virus group. Overall, these results are important in understanding the cell localization of TSHSV and the immune response of infected turtles.

Abstract
Background:Interstitial lung diseases (ILD) could originate from idiopathic cause or secondary to connective tissue diseases (CTD). The most common causes of CTD associated ILD (CTD-ILD) include mixed connective tissue disease, systemic sclerosis (SSc), inflammatory myositis such as polymyositis (PM) and dermatomyositis (DM). Our preliminary data had demonstrated that ILD is not uncommon in patients with rheumatoid arthritis (RA) and Sjogren’s syndrome (SS) in Asia. Myositis-specific autoantibodies (MSAs) and myositis associate autoantibodies (MAAs) have been used for the early diagnosis of PM/DM and could be noticed in patients with idiopathic ILD. Our previous data also had identified that MSA/MAA were detected quite often in patients with CTD-ILD in addition to inflammatory myositis. Nonetheless, a specific group of ILD patients like interstitial pneumonia with autoimmune features (IPAF) are still challenging for pomologists, rheumatologist and radiologists, either in accurate diagnosis or treatment.Objectives:We aimed to identify the prevalence of serum MSA/MAAs and clinical diagnosis on imaging in patients with IPAF and CTD-ILD and define the correlation between MSA/MAA and clinical imaging features.Methods:Patients who had been suspected with autoimmune rheumatic diseases in the presence of interstitial lung diseases were included in this prospective study at a single medical center in Taiwan between February 2018 and November 2019. All enrolled patients had experienced clinical symptoms of ILD and been identified abnormalities on the chest plain films. All patients were inspected by both pulmonologists and rheumatologist. Computed tomography scans of chest had been reviewed by at least two pulmonary radiologists. Serological immunotherapy strips were performed to detect MSA/MAAs. Correlation analysis was performed among the different collected variables.Results:870 patients were reviewed by both pulmonologists and rheumatologists and received blood sampling including autoantibody profiling and MSA/MAA tests. The clinical diagnosis of CTD-ILD or IPAF were confirmed in 603 patients, who received 1078 chest CT scan due to clinically suspected CTD-ILD or IPAF. 33 patients received lung biopsies since other CTD-ILD or IPAF patients hesitate to receive invasive procedures. 78 patients had been admitted to intensive care units and received mechanical ventilation and were not suitable for lung biopsies. 22 of 33 patients received more than twice lung biopsies due to challenging diagnosis. 6 patients with CTD-ILD or IPAF had received extracorporeal membrane oxygenation (ECMO) due to ILD with secondary pulmonary infection and acute respiratory distress syndrome. The most commom detected MSA/MAA were anti-Ro-52 (27%), followed by anti-Ku (3.9%), and anti-Mi-2 (3.6%).SS is the most common rheumatic disease in patients with CTD-ILD. MSA/MAAs were identified in patients with IPAF (36.4 %) in the absence of specific rheumatic diseases. Anti-nuclear antibody (27.4%), rheumatoid factor immunoglobulin M (21.6%) and anti-Ro (13.7%) were the most common autoantibodies identified in patients with IPAF. Anti-Ro-52 was positively corelated with nonspecific interstitial pneumonia in patients with CTD-ILD or IPAF, Phi= 0.371 and 0.326, both p < 0.001, respectively.Conclusion:Early diagnosis of CTD-ILD and IPAF is still challenging for both pulmonologists, rheumatologists and radiologists. Identifying how serum MSA/MAAs contribute clinical manifestations on chest CT imaging is warranted and help clinical physicians and patients recognize the necessity of lung biopsy to reduce comorbidity.References:[1]Jee AS, et al.

Abstract
Trionyx sinensis Hemorrhagic Syndrome Virus (TSHSV) is the firstly discovered aquatic arterivirus inducing high mortality of Trionyx sinensis. So far, the lack of genomic resources has hindered further research on revealing the immunological characteristics of T. sinensis in response to TSHSV. In the present study, we performed a transcriptome analysis from the lungs of T. sinensis challenged by TSHSV using Illumina-based RNA-Seq. The validity of transcriptomic data was confirmed with the gradual increase of TSHSV RNA copies detected in lung. A total of 103079339 clean reads were generated, and 58374764 unique mapped reads were analyzed. Assembly of the sequence data allowed identifying 16383 unigenes consisting of 36 significant differentially expressed genes (DEGs). These DEGs were categorized into 30 GO-enriched bioprocesses and 9 KEGG pathways. The combinational analysis of GO-enriched bioprocesses and KEGG pathways demonstrated that TSHSV modulated several immune genes of T. sinensis related to various biological processes, including virus recognition (RIG-I/MDA-5), immune initiation (IFIT-1 and IFIT-5), endocytosis (CUBN, ENPP2 and LRP2) and steroid metabolism (FCNIL and STAR). In summary, the finding of this study revealed several immune pathways and candidated genes involved in the immune response of T. sinensis against TSHSV-infection. These results will provide helpful information to investigate molecular mechanism of T. sinensis in response to TSHSV.

Abstract
Trionyx sinensis hemorrhagic syndrome virus (TSHSV) is a newly discovered lethal arterivirus that causes serious disease in Trionyx sinensis in China. In this study, the complete genome sequence of TSHSV was determined by RACE cloning, and the functions of the predicted proteins were predicted. The complete genome of TSHSV was found to be 17,875 bp in length, and a 3'-end poly(A) tail was detected. Eight TSHSV hypothetical proteins (TSHSV-HPs) were predicted by gene model identification. TSHSV-HP2, 3 and 4 were associated with replicase activity, since papain-like protease (PLPs), serine-type endopeptidase, P-loop-containing nucleoside triphosphate hydrolase, and EndoU-like endoribonuclease motifs were detected. Phylogenetic analysis showed that TSHSV clusters with an arterivirus from a Chinese broad-headed pond turtle.

Abstract
Objective: To compare the efficacy and safety of active transfer of plaque (ATP) versus provisional stenting (PS) with drug-eluting stents (DES) for the treatment of coronary bifurcation lesions. Methods: A total of 1 136 patients with bifurcation lesions hospitalized in 6 selected hospitals between January 2010 and January 2014 were included in this prospective observational trial, patients were divided into either ATP (n=560) or PS group (n=576) accordingly. The primary endpoint was target lesion revascularization within 1 year, and the second endpoints were all-cause death, cardiogenic death, myocardial infarction, stent thrombosis, stroke, recurrent angina within 1 year. Results: There were no significant differences in age, sex, hypertension, diabetes, hyperlipidemia and smoking history between the two groups (P>0.05). The incidence of TIMI blood flow <3 grade in the side branch (1.6%(9/560) vs. 7.5% (43/576), P<0.01), acute occlusion of the side branch (1.3%(7/560) vs. 7.1%(41/576), P<0.01) and implanted stents of side branch (1.8%(10/560) vs. 7.8% (45/576), P<0.01) were significantly lower in the ATP group than those in the PS group. During the one year follow up, the rate of target lesion revascularization was similar between ATP group and PS group (4.6%(26/560) vs. 4.0%(23/576), P=0.66). Conclusions: The effectiveness and safetyof ATP techniquein the patients with coronary bifurcation lesions is comparable to the PS technique. However, ATP technique is superior to PS technique on effectively reducing the incidence of implanted stents in the side branch.

Abstract
Objective: To investigate the concept of hepatitis B virus (HBV)-related acute-on-chronic pre-liver failure (pre-ACLF), and to develop and evaluate the diagnostic criteria for this disease. Methods: A retrospective analysis was performed for the clinical data of 754 patients with severe acute exacerbation (SAE) of HBV-related chronic liver disease, and their clinical features were identified. A multivariate logistic regression analysis was used to determine the risk factors for acute-on-chronic liver failure (ACLF). The inclusion rate of patients with SAE-HBV-related chronic liver disease and the detection rate of ACLF patients were analyzed to evaluate the value of four different versions of diagnostic criteria for pre-liver failure. The t-test, an analysis of variance, the Mann-Whitney U test, and the chi-square test were used for statistical analysis based on data type. Results: The incidence rate of ACLF in the patients with SAE-HBV-related chronic liver disease was 9.9% and the time to progression to ACLF was 12.0 ± 6.7 days. The multivariate logistic regression analysis showed that HBV reactivation (odds ratio [OR] = 5.118), direct bilirubin ratio (D/T) (OR = 1.041), age (OR = 1.033), total bilirubin (TBil) (OR = 1.005), prothrombin activity (PTA) (OR = 0.880), and serum sodium (Na) (OR = 0.918) were independent risk factors for ACLF. Group B (51.3 μmol/L < TBil < 171.1 μmol/L and 40%≤PTA < 60%, 4.2%) had a significantly lower incidence rate of ACLF than group A (51.3 μmol/L < TBil < 171.1 μmol/L and PTA < 40%, 13.7%) and group C (TBil > 171.1 μmol/L and 40% < PTA < 60%, 20.3%) (P < 0.001). Group C had a significantly shorter time to progression to ACLF than group A (10.5 ± 6.1 days vs 15.6 ± 7.4 days, P = 0.008). A total of 45 patients met the diagnostic criteria developed by Chongqing and the incidence rate of ACLF was 2.2%; 154 patients met the diagnostic criteria developed by Zhejiang and the incidence rate of ACLF was 7.1%; 188 patients met the diagnostic criteria in the Chinese guidelines and the incidence rate of ACLF was 6.4%; 117 patients met the diagnostic criteria for SAE-CHB and the incidence rate of ACLF was 9.4%. Conclusion: At present, these four versions of diagnostic criteria for pre-liver failure are not fully applicable to the clinical practice in China. The diagnostic criteria for HBV-related pre-ACLF should include important assessment indices which affect its progression to ACLF.

Abstract
Photosynthetic microalgae can capture solar energy and convert it to bioenergy and biochemical products. In nature or industrial processes, microalgae live together with bacterial communities and may maintain symbiotic relationships. In general interactions, microalgae exude dissolved organic carbon that becomes available to bacteria. In return, the bacteria remineralize sulphur, nitrogen and phosphorous to support the further growth of microalgae. In specific interactions, heterotrophic bacteria supply B vitamins as organic cofactors or produce siderophores to bind iron, which could be utilized by microalgae, while the algae supply fixed carbon to the bacteria in return. In this review, we focus on mutualistic relationship between microalgae and bacteria, summarizing recent studies on the mechanisms involved in microalgae-bacteria symbiosis. Symbiotic bacteria on promoting microalgal growth are described and the relevance of microalgae-bacteria interactions for biofuel production processes is discussed. Symbiotic microalgae-bacteria consortia could be utilized to improve microalgal biomass production and to enrich the biomass with valuable chemical and energy compounds. The suitable control of such biological interactions between microalgae and bacteria will help to improve the microalgae-based biomass and biofuel production in the future.

Abstract
In our previous research, we identified a QTL with an interval of 3.4 Mb for growth on chicken chromosome (GGA) 4 in an advanced intercross population of an initial cross between the New Hampshire inbred line (NHI) and the White Leghorn inbred line (WL77). In the current study, an association analysis was performed in a population of purebred white layers (WLA) with White Leghorn origin. Genotypic data of 130 SNPs within the previously identified 3.4-Mb region were obtained using a 60K SNP chip. In total, 24 significant SNPs (LOD ≥ 4.44) on GGA4 were detected for daily weigh gain from 8 to 14 weeks and two SNPs (LOD ≥ 4.80) for body weight at 14 weeks. The QTL interval was reduced by 1.9 Mb to an interval of 1.5 Mb (74.6-76.1 Mb) that harbors 15 genes. Furthermore, to identify additional loci for chicken growth, a genome-wide association study (GWAS) was carried out in a WLA population. The GWAS identified an additional QTL on GGA6 for body weight at six weeks (19.8-21.2 Mb). Our findings showed that by using a WLA population we were able to further reduce the QTL confidence interval previously detected using a NHI × WL77 advanced intercross population.

Abstract
OBJECTIVE To investigate the risk factors for the short-term outcome of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF), and to establish a risk model for predicting the short-term outcome of these patients. METHODS A total of 338 patients with HBV-related ACLF who were admitted to 30 Lod hospital of PLA hospital from January 2010 to January 2014 were enrolled, and a prospective clinical follow-up was performed for them. Multivariate logistic regression was used to determine the risk factors for short-term (12 weeks) outcome, the predictive model with logistic regression equation was established, and the predictive value of this model was evaluated. RESULTS The multivariate logistic regression analysis showed that age, a family history of hepatitis B, hepatic encephalopathy (HE), hepatorenal syndrome (HRS), white blood cell (WBC), platelet (PLT), international normalized ratio (INR), total bilirubin (TBil), total bile acid (TBA), creatinine, Na, HBV DNA, and HBeAg were the independent risk factors for the short-term outcome of these patients. Logistic(p) = -4.466 + 1.192 age + 1.631 family history of hepatitis B + 1.091 HE + 1.631 HRS + 1.208 WBC -1.487 PLT + 1.092 INR + 1.446 TBil + 1.608 TBA -1.101 CHE + 1.279 CRE -1.713 Na + 1.032 HBV DNA + 0.833 HBeAg. The area under the receiver operating characteristic curve of the model for the prediction of short-term outcome was 0.930, the cut-off value was 3.16, the sensitivity was 0.860, and the specificity was 0.871. With the increasing scores of the equation, the mortality of patients tended to increase gradually. CONCLUSION Age, a family history of hepatitis B, HE, HRS, WBC, PLT, INR, TBil, TBA, CHE, CRE, Na, HBV DNA, and HBeAg are the independent risk factors for the short-term outcome of patients with HBV-related ACLF. The model for predicting short-term outcome established on the basis of independent risk factors has a better clinical value in guiding clinical therapy.

Abstract
In our previous research, QTL analysis in an F2 cross between the inbred New Hampshire (NHI) and White Leghorn (WL77) lines revealed a growth QTL in the distal part of chromosome 4. To physically reduce the chromosomal interval and the number of potential candidate genes, we performed fine mapping using individuals of generations F10 , F11 and F12 in an advanced intercross line that had been established from the initial F2 mapping population. Using nine single nucleotide polymorphism (SNP) markers within the QTL region for an association analysis with several growth traits from hatch to 20 weeks and body composition traits at 20 weeks, we could reduce the confidence interval from 26.9 to 3.4 Mb. Within the fine mapped region, markers rs14490774, rs314961352 and rs318175270 were in full linkage disequilibrium (D' = 1.0) and showed the strongest effect on growth and muscle mass (LOD ≥ 4.00). This reduced region contains 30 genes, compared to 292 genes in the original region. Chicken 60 K and 600 K SNP chips combined with DNA sequencing of the parental lines were used to call mutations in the reduced region. In the narrowed-down region, 489 sequence variants were detected between NHI and WL77. The most deleterious variants are a missense variant in ADGRA3 (SIFT = 0.02) and a frameshift deletion in the functional unknown gene ENSGALG00000014401 in NHI chicken. In addition, five synonymous variants were discovered in genes PPARGC1A, ADGRA3, PACRGL, SLIT2 and FAM184B. In our study, the confidence interval and the number of potential genes could be reduced 8- and 10- fold respectively. Further research will focus on functional effects of mutant genes.

Abstract
Farming of Eriocheir sinensis was seriously threaten by the infection of opportunistic pathogens, especially the gram-negative bacterium. In this paper, we analyzed the sequence of extracellular signal-regulated kinases 2 (ERK2) of E. sinensis (EsERK2) and its expression levels after challenge with LPS and Aeromonas hydrophila in both in vivo and in vitro examination. The full-length cDNA sequence of EsERK2 was 2455 bp in size with an open reading frame (ORF) of 1095 bp, encoding the protein of 365 amino acids. It owned a predicted molecular mass of 42.4 kDa and a theoretical isoelectric point (pI) of 5.93. EsERK2 was distributed in all examined tissues including haemocyte, gonad, hepatopancreas, gill, muscle heart, stomach and intestine, but its expression level was significantly higher in hepatopancreas than it in other examined tissues. The expression level of EsERK2 increased significantly after LPS challenge at 2 h (P < 0.05), and then gradually increased and reached highest at 16 h. However, its expression level decreased significantly after A. hydrophila challenge at 4 h, and then gradually decreased till 24 h (P < 0.05), and returned to its initial value at 36 h. According to the immunofluorescence assay and western blotting assay, EsERK2 was found to be distributed mainly in cytoplasm of haemocyte, and its expression level showed a prominent boost in primary cultured haemocytes after challenge with LPS and A. hydrophila in vitro. These results indicated that the expression of EsERK2 was sensitive to the exterior stimulants and its encoding protein might be associated with the signaling transduction in response to exterior pathogens in E. sinensis.

Abstract
Pathogenicity and immune responses were characterized in commercial broilers and layers challenged with very virulent infectious bursal disease virus (vvIBDV) reassortants (vvIBDV segment A + serotype 2 segment B and vvIBDV segment A + classic virulent segment B) at 7 days of age. In addition, functional immunosuppression was evaluated after challenge with infectious bronchitis virus (IBV) at 15 days of age. Layers showed higher levels and increased persistence of IBDV- and IBV-specific maternal antibodies than broilers at 1, 13, and 28 days of age. Cytokine gene expression was evaluated, after IBDV challenge, as an indicator of the innate immune function. Similar results were detected between the groups inoculated with vvIBDV reassortants. Interleukin-1β (IL-1β) in the bursa of layers demonstrated down-regulation at 1 day postinfection (DPI; 8 days of age), and no changes at 4 DPI (11 days of age) compared with controls. In broilers, IL-6 expression in the bursa was down-regulated 1 DPI (8 days of age) and up-regulated at 4 DPI (11 days of age). A significant lymphoid depletion was detected at 21 DPI (28 days of age) in broilers exposed to a reassortant of vvIBDV segment A and classic virulent IBDV segment B. Finally, reduced specific antibodies against IBV measured 13 days after challenge were detected in layer and broiler chickens inoculated with a reassortant serotype 2 IBDV in segment B, suggesting functional immunosuppression. These results provide evidence indicating that current IBDV vaccination of breeders does not completely protect progeny chickens from challenge with reassortant vvIBDV.

Abstract
Two hundred ninety isolates of Escherichia coli were investigated for the production of extended-spectrum beta-lactamases (ESBLs). Fourteen (4.8%) of the 290 strains were found to produce ESBLs. Each of the 14 strains produced one or two ESBLs, as follows: 10 strains produced TEM-52, 1 strain produced SHV-2a, 1 strain produced SHV-12, 1 strain produced a CMY-1-like enzyme, and 1 strain expressed SHV-2a and a CMY-1-like enzyme. Another two strains for which the MICs of ceftazidime and cefoxitin were high, were probable AmpC enzyme hyperproducers. Because of the high prevalence of TEM-52 in E. coli isolates, we further investigated the TEM-type ESBLs produced by Klebsiella pneumoniae in order to observe the distribution of TEM-52 enzymes among Enterobacteriaceae in Korea. All TEM enzymes produced by 12 strains of K. pneumoniae were identified as TEM-52. To evaluate the genetic relatedness among the organisms, ribotyping of TEM-52-producing E. coli and K. pneumoniae was performed. The ribotyping profiles of the organisms showed similar but clearly different patterns. In conclusion, TEM-52 is the most prevalent TEM-type ESBL in Korea.
