Abstract
To explore the efficacy and safety of a small-volume-plasma artificial liver support system (ALSS) in the treatment of acute-on-chronic liver failure (ACLF). A retrospective analysis was performed. All ACLF patients received ALSS of plasma exchange & double plasma molecular absorb system (PE+DPMAS) treatment, and successfully completed this treatment. Patients were divided into small-volume and half-volume plasma groups. We compared the changes of the indicators on liver function, kidney function, blood coagulation function, and blood ammonia level before and after PE+DPMAS treatment; we compared the short-term and long-term curative effects between small-volume and half-volume plasma groups; and the factors influencing Week 4 and Week 12 mortality of ACLF patients were analyzed. The Week 4 improvement rates were 63.96 % and 66.86 % in the small-volume and half-volume plasma groups, respectively. The Week 12 survival rates in the small-volume-plasma and half-volume plasma groups were 66.72 % and 64.61 %, respectively. We found several risk factors affecting Week 4 and Week 12 mortality. Kaplan-Meier survival curves suggested no significant difference in Week 4 and Week 12 survival rates between the small-volume and half-volume plasma groups (P=0.34). The small-volume-plasma PE+DPMAS treatment could effectively reduce bilirubin and bile acids, and this was an approach with high safety and few complications, similar to the half-volume-plasma PE+DPMAS treatment. The small-volume-plasma PE+DPMAS has the advantage of greatly reducing the need for intraoperative plasma, which is especially of importance in times of shortage of plasma.

Abstract
PURPOSE/OBJECTIVE(S) HCC accounts for 75-90% of all primary liver cancers, the majority of which are treated with liver-directed therapy. Treatment response and recurrence are difficult to discern using conventional imaging with MR/CT. Tumor-selective PET imaging could help with clinical management in this setting. Here, we engineer HN3, a single-domain antibody (nanobody) specific to GPC3, a histopathologically-defining HCC marker, as an immunoPET agent. We compared both conventional and sortase-based site-specific modification methods for synthesizing HN3 immunoPET tracers. MATERIALS/METHODS Stochastic lysine conjugation with deferoxamine (DFO-NCS) was done to synthesize nHN3-DFO. ssHN3-DFO was engineered utilizing sortase-mediated conjugation of HN3 containing an LPETG C-terminal tag and a triglycine-DFO chelator. Biolayer interferometry (BLI) and radioligand saturation assays were done to determine binding affinity pre- and post-Zirconium-89 labeling. Following, PET/CT with a terminal 3-hour biodistribution was done in mice inoculated with isogenic A431 and A431-GPC3+ xenografts to determine conjugate specificity for GPC3. Finally, conjugates were evaluated in a HepG2 liver cancer model via ex vivo biodistribution studies and a comparative PET/CT study in mice bearing HepG2 tumors that were imaged with both [18F]FDG and 89Zr-ssHN3. RESULTS Both conjugates exhibited nanomolar binding affinity for GPC3 in vitro (11-30 nM for nHN3 and 10-15 nM for ssHN3). A431 and A431-GPC3+ PET/CT and biodistribution studies showed specificity to GPC3 by both probes, with more favorable tumor uptake by 89Zr-ssHN3 at 3 hours post-injection (14% IA/g vs. 7% IA/g for nHN3). Both tracers also displayed uptake in HepG2 (GPC3+) liver tumors, again with the site specifically conjugated probe having higher tumor accumulation and lower liver signal than the conventionally modified HN3 (7% IA/g vs. 5 % IA/g for tumor and 2% IA/g vs. 4% IA/g for liver at 1-hour post-injection). PET/CT studies in mice imaged with [18F]FDG and 89Zr-ssHN3 demonstrated more consistent tumor accumulation for the nanobody conjugate (4/4 mice had uptake by the tumor vs. 1/4 for FDG). CONCLUSION We successfully designed, synthesized, and characterized novel GPC3-selective nanobody PET probes that can image liver tumors in vivo. The site-specifically conjugated tracer showed more favorable biodistribution and pharmacokinetic properties, resulting in a much higher tumor: liver signal compared to 89Zr-nHN3. We also show the superiority of the 89Zr-ssHN3 imaging over conventional [18F]FDG, highlighting a clear advantage in using targeted tumor imaging for this cancer type. Successful translation of the site-specifically conjugated nanobody may ultimately aid in characterizing lesions following liver-directed therapy and allow for more comprehensive screening, early diagnosis, and post-treatment surveillance of HCC.

Abstract
OBJECTIVE To propose a semi-supervised material quantitative intelligent imaging algorithm based on prior information perception learning (SLMD-Net) to improve the quality and precision of spectral CT imaging. METHODS The algorithm includes a supervised and a self- supervised submodule. In the supervised submodule, the mapping relationship between low and high signal-to-noise ratio (SNR) data was constructed through mean square error loss function learning based on a small labeled dataset. In the self- supervised sub-module, an image recovery model was utilized to construct the loss function incorporating the prior information from a large unlabeled low SNR basic material image dataset, and the total variation (TV) model was used to to characterize the prior information of the images. The two submodules were combined to form the SLMD-Net method, and pre-clinical simulation data were used to validate the feasibility and effectiveness of the algorithm. RESULTS Compared with the traditional model-driven quantitative imaging methods (FBP-DI, PWLS-PCG, and E3DTV), data-driven supervised-learning-based quantitative imaging methods (SUMD-Net and BFCNN), a material quantitative imaging method based on unsupervised learning (UNTV-Net) and semi-supervised learning-based cycle consistent generative adversarial network (Semi-CycleGAN), the proposed SLMD-Net method had better performance in both visual and quantitative assessments. For quantitative imaging of water and bone materials, the SLMD-Net method had the highest PSNR index (31.82 and 29.06), the highest FSIM index (0.95 and 0.90), and the lowest RMSE index (0.03 and 0.02), respectively) and achieved significantly higher image quality scores than the other 7 material decomposition methods (P < 0.05). The material quantitative imaging performance of SLMD-Net was close to that of the supervised network SUMD-Net trained with labeled data with a doubled size. CONCLUSIONS A small labeled dataset and a large unlabeled low SNR material image dataset can be fully used to suppress noise amplification and artifacts in basic material decomposition in spectral CT and reduce the dependence on labeled data-driven network, which considers more realistic scenario in clinics.

Abstract
A life cycle-based environmental assessment was conducted on the mitigation of landfill gas emissions, by implementing biocover and gas collection along with energy utilisation at aging landfills. Based on recent studies about gas generation at Danish landfills, the efficiency of the mitigation technologies involved and the composition of substituted energy production, 15 scenarios were modelled using the EASETECH life cycle assessment model, through which potential environmental impacts in the category "Climate change" were calculated. In all scenarios, biocover and gas collection systems with energy utilisation led to significant environmental improvements compared to the baseline scenario with no emission mitigation action. Scenarios representing biocovers with methane oxidation efficiencies between 70 and 90 % were environmentally superior in terms of climate change impact - in comparison to scenarios with 20-30 years of gas collection and energy utilisation (collection efficiencies between 40 and 80 %). Combining gas collection with energy utilisation and the subsequent installation of a biocover saw major improvements in comparison to where only gas collection and energy utilisation were in effect. Overall, it can be concluded that a biocover under the given assumptions is environmentally more appropriate than gas collection and utilisation at aging landfills, mainly due to methane emissions escaping through the landfill cover during and after the gas collection period playing a crucial role in the latter situation. Maintaining high methane oxidation efficiency for a biocover throughout the lifetime of a landfill is vital for reducing environmental impacts.

Abstract
OBJECTIVE The aim of this study was to compare the effect of different administration modalities of methotrexate (MTX)/mifepristone in the initial medication stage, followed by embryo transfer in the treatment of caesarean scar pregnancy (CSP). PATIENTS AND METHODS A retrospective analysis of 66 CSP patients who received treatment in our hospital from January 2015 to July 2021 was performed, and participants were divided into three groups: Group one (n=14) received mifepristone followed by embryo removal treatment, Group two (n=29) received MTX followed by embryo removal, and Group three (n=23) received a methotrexate/mifepristone combined treatment followed by embryo removal. The basic findings were analysed, along with the curative effects between the three groups. Risk factors predicting additional treatment after initial intervention failure were analysed. RESULTS There were statistically significant differences in gestational age, hospitalization days, costs, myometrial thickness, cardiac activity, and mean sac diameter between groups (p<0.05) after grouping by eight weeks. The initial intervention success rates were 92.86%, 89.66%, and 65.22% in Group one, two, and three, respectively (p<0.05), while the complication rates were 14.29%, 6.90%, and 26.87%, respectively (p>0.05). After grouping according to eight weeks of gestational age, the difference in initial serum β-hCG between Group two and three was statistically significant (p<0.05). Mean sac diameter was a risk factor for additional treatment after initial intervention failure, with an odds ratio of 1.113 (p<0.05). A cut-off of 22.75 mm was a preferable indicator. CONCLUSIONS MTX/mifepristone followed by embryo removal is a reliable way to treat CSP. Mean sac diameter was a risk factor for additional treatment after initial intervention failure.

Abstract
Lipid metabolism is an important biochemical process in the body. Recent studies have found that environmental endocrine disruptors play an important role in the regulation of lipid metabolism. Bisphenol A (BPA), a common environmental endocrine disruptor, has adverse effects on lipid metabolism, but the mechanism is still unclear. This study aimed to investigate the effects of gestational BPA exposure on hepatic lipid metabolism and its possible mechanism in male offspring. The pregnant Sprague-Dawley rats were exposed to BPA (0, 0.05, 0.5, 5 mg/kg/day) from day 5 to day 19 of gestation to investigate the levels of triglyceride (TG) and total cholesterol (TC), and the expression of liver lipid metabolism-related genes in male offspring rats. The results showed that compared with the control group, the TG and TC levels in serum and liver in BPA-exposed groups was increased. And the expressions of liver fatty acid oxidation related genes, such as peroxisome proliferators-activated receptor α (PPARα) and carnitine palmitoyl transferase 1α (CPT1α), were down-regulated. However, the expressions of fatty acid synthesis related genes, such as sterol regulatory element binding proteins 1 (SREBP-1), acetyl-CoA carboxylase 1 (ACC1), fatty acid synthase (FAS) and stearoyl-CoA desaturase 1 (SCD-1), were up-regulated. The increased protein levels of mTOR and p-CRTC2 suggested that CREB-regulated transcription coactivator 2 (CRTC2) might be an important mediator in the mTOR/SREBP-1 pathway. In conclusion, these results demonstrated that mTOR/CRTC2/SREBP-1 could be affected by gestational BPA exposure, which may involve in the lipid metabolic disorders in later life.

Abstract
Porcine circovirus type 2 (PCV2) can cause various clinical diseases in pigs, resulting in huge losses for the pig farms all over the world. In order to develop a new strategy to control PCV2, it is essential to understand its mechanisms firstly, especially PCV2 interferes with the host's innate immunity. In the present study, lncRNA and mRNA expression profiles in porcine lymphnode response to PCV2 infection were deeply sequenced and analyzed. 3271 novel lncRNAs were identified in all. 1898 mRNAs and 282 lncRNAs showed differential expression between control and PCV2-infected groups. The bioinformatics analysis including lncRNA-mRNA co-expression network construction, as well as GO and KEGG pathway analysis focused on the DEGs was carried out. The results indicated that lncRNAs might participate in PCV2 infection-induced the pathogenesis of immunosuppression through regulating the host's immune responses, biological regulation, response to stimulus, cellular component organization or biogenesis and metabolism. And these differentially expressed lncRNAs might play important roles in response to PCV2 infection in the host's innate immune system. These findings provided a large-scale survey of dysregulated lncRNAs after PCV2 infection, especially the lncRNAs responded to host's innate immune within the lymphnode. This study will provide a novel insight into the lncRNAs' functions and the possible immunosuppressive mechanism induced by PCV2 infection. However, further research will be required to verify the characteristic function of the dysregulated lncRNAs.

Abstract
In this work, we show an obvious evidence of nondestructive Raman spectra for the structural transition, i.e., the existence of a charge density wave (CDW) in monolayer 2H-TaS2, which can exhibit a much higher transition temperature than bulk and results in additional vibrational modes, indicating strong interactions with light. Furthermore, we reveal that the degenerate breath and wiggle modes of 2H-TaS2 originated from the periodic lattice distortion can be probed using the optical methods. Since recently several light-tunable devices have been proposed based on the CDW phase transition of 1 T-TaS2, our study and in particular, the theoretical results will be very helpful for understanding and designing electronic devices based on the CDW of 2H-TaS2.

Abstract
Diarrhea caused by Enterotoxigenic Escherichia coli (ETEC) causes high levels of morbidity and mortality in neonatal piglets. Owing to the abuse of antibiotics and emergence of drug resistance, antibiotics are no longer considered only beneficial, but also potentially harmful drugs. Supplements that can inhibit the growth of bacteria are expected to replace antibiotics. Tea polyphenols have numerous important biological functions, including antibacterial, antiviral, antioxidative, anti-inflammatory, and antihypertensive effects. We investigated the role of tea polyphenols in ETEC K88 infection using a mouse model. Pretreating with tea polyphenols attenuated the symptoms induced by ETEC K88. Furthermore, in a cell adherence assay, tea polyphenols inhibited ETEC K88 adherence to IPEC-J2 cells. When cells were infected with ETEC K88, mRNA and protein levels of claudin-1 were significantly decreased compared with those of control cells. However, when cells were pretreated with tea polyphenols, claudin-1 mRNA and protein levels were higher than those in cells without pretreatment upon cell infection with ETEC K88. TLR2 mRNA levels were also higher following cell infection with ETEC K88 when cells were pretreated with tea polyphenols. These data revealed that tea polyphenols could increase the barrier integrity of IPEC-J2 cells by upregulating expression of claudin-1 through activation of TLR2. Tea polyphenols had beneficial effects on epithelial barrier function. Therefore, tea polyphenols could be used as a novel strategy to control and treat pig infections caused by ETEC K88.

Abstract
Porcine epidemic diarrhea virus (PEDV) is a leading cause of diarrhea in pigs worldwide. Virus isolation and genetic evolutionary analysis allow investigations into the prevalence of epidemic strains and provide data for the clinical diagnosis and vaccine development. In this study, we investigated the genetic characteristics of PEDV circulation in Asia through virus isolation and comparative genomics analysis. APEDV strain designated HB2018 was isolated from a pig in a farm experiencing a diarrhea outbreak. The complete genome sequence of HB2018 was 28,138 bp in length. Phylogenetic analysis of HB2018 and 207 PEDVs in Asia showed that most PEDV strains circulating in Asia after 2010 belong to genotype GII, particularly GII-a. The PEDV vaccine strain CV777 belonged to GI, and thus, unmatched genotypes between CV777 and GII-a variants might partially explain incomplete protection by the CV777-derived vaccine against PEDV variants in China. In addition, we found the S protein of variant strains contained numerous mutations compared to the S protein of CV777, and these mutations occurred in the N-terminal domain of the S protein. These mutations may influence the antigenicity, pathogenicity, and neutralization properties of the variant strains.

Abstract
Bacillus cereus (B. cereus) is widely distributed in the environment. It is one of the most common opportunistic food-borne pathogens associated with food poisoning, not only being majorly reported to cause fatal infections of the gastrointestinal tract, but also responsible for abdominal distress and vomiting. The current study was undertaken to evaluate the biological characteristics and the genetic evolution of B. cereus isolated from infected organs of dead Elaphurus davidianus (E. davidianus). B. cereus was characterized through antibiotic sensitivity tests, mouse lethality assay, whole genome sequencing analysis, and genome annotation. The results revealed that the isolated B. cereus strain was highly resistant to rifampicin, lincomycin, sulfamethoxazole, erythromycin, and ampicillin, with a high pathogenicity phenotype. KEGG annotation revealed that "metabolic pathways" had the largest number of unigenes, followed by "biosynthesis of secondary metabolites" and "biosynthesis of antibiotics". GO analysis resulted in 8039 unigenes categorized. Meanwhile, 54,779 unigenes were annotated and grouped into 23 categories based on COG functional classifications. Moreover, one gene (codY) was found to be related to the host in conformity with the analysis done on PHI-base. Other tests led to the identification of 16 B. cereus virulence factor genes and five resistance types, with potential resistance against bacitracin, penicillin, and fosfomycin. We isolated a highly drug-resistant and pathogenic B. cereus strain from E. davidianus, showing that a variety of antimicrobial drugs should be avoided in clinical treatments. Furthermore, to the best of our knowledge, this is the first study to report whole genome sequencing of a emergence of food-borne B. cereus strain isolated from E. davidianus deer; it will be helpful to extensively investigate the genetic and molecular mechanisms of drug resistance and pathogenesis about B. cereus in both humans and animals.

Abstract
A continuous-wave (CW) Scheimpflug underwater multi-spectral lidar system was constructed to monitor aquatic fauna with spatial, spectral, and temporal resolution. Utilizing a 1 W 414 nm diode laser and a detection set-up with a reflective grating, measurements of shrimp pleopod movements at fixed range, and the swimming of small fish trapped in a clear tube were performed in a 5 m ×0.6 m ×0.6 m water tank. The spatial resolution is about 5 mm, the spectral resolution is 10 nm (from 400 nm to 700 nm), and with proper binning of the CCD, a read-out repetition rate up to 150 Hz can be reached. The experimental results demonstrate that the underwater Scheimpflug lidar system has great potential for detailed monitoring of the small aquatic fauna in oceanic environments.

Abstract
Pulmonary arterial hypertension (PAH), also known as broilers ascites syndrome, is characterized by hypoxia, pulmonary artery pressure, and right heart failure. However, less information is available about the molecular mechanisms of PAH. We evaluated the mediation of calcium-sensing receptor by inducing hypoxia for the possible proliferation of pulmonary artery smooth muscle cells via the G protein pathway. For this purpose, we used an in vitro trial of chicken cell culture and confirmed our results by using immunohistochemistry, immunofluorescence staining, quantitative real-time polymerase chain reaction assay, and Western blotting analysis. Our results showed that the mRNA and protein expression levels of calcium-sensing receptor (CaSR) were significantly upregulated in cells when co-incubated with CaCl2. However, the levels of mRNA and protein were obviously decreased when supplemented with blocking agents (NiCl2, 2-APB, and D609). Furthermore, the experimentally induced hypoxia also upregulated the expression of CaSR gene as compared to CaSR gene expression in control cells. Together, these results indicate that hypoxia plays an important role in the expression of CaSR gene in pulmonary artery smooth muscle cells and reveals new targets for the CaSR excited hypothesis to prevent and control PAH in chickens.

Abstract
BACKGROUND A diagnostic method to simultaneously detect and discriminate porcine circovirus type 1 (PCV1), porcine circovirus type 2 (PCV2) and porcine circovirus type 3 (PCV3) in clinical specimens is imperative for the differential diagnosis and monitoring and control of PCVs in the field. METHODS Three primer pairs were designed and used to develop a multiplex PCR assay. And 286 samples from 8 farms in Hubei province were tested by the developed multiplex PCR assay to demonstrate the accuracy. RESULTS Each of target genes of PCV1, PCV2 and PCV3 was amplified using the designed primers, while no other porcine viruses genes were detected. The limit of detection of the assay was 10 copies/μL of PCV1, PCV2 OR PCV3. The results of the tissue samples detection showed that PCV1, PCV2 and PCV3 are co-circulating in central China. The PCV1, PCV2 and PCV3 singular infection rate was 52.4% (150/286), 61.2% (175/286) and 45.1% (129/286), respectively, while the PCV1 and PCV2 co-infection rate was 11.2% (32/286), the PCV1 and PCV3 co-infection rate was 5.9% (17/286), the PCV2 and PCV3 co-infection rate was 23.4% (67/286), and the PCV1, PCV2 and PCV3 co-infection rate was 1.7% (5/286), respectively, which were 100% consistent with the sequencing method and real-time PCR methods. CONCLUSIONS The multiplex PCR assay could be used as a differential diagnostic tool for monitoring and control of PCVs in the field. The results also indicate that the PCVs infection and their co-infection are severe in Hubei province, Central China.

Abstract
Abstract
Along with the urbanization process, large amount of construction and demolition (C&D) waste during the construction, reconstruction, expansion or demolition of buildings is generated. Meanwhile, the impact on environment due to natural aggregate mining has become increasingly significant. These factors have driven the building industry to look for environmentally friendly materials and focusing on sustainable construction. Through nearly a decade of research, recycled concrete (RC) made with recycled aggregates manufactured from construction and demolition (C&D) waste has shown a competitive performance compared to natural materials and has already achieved industrial application. Researches on sustainably recycled concrete have become an essential part of sustainable development and continue to play a vital role for future research.
This paper engages in the discussion and the overview of research done by the Research Group for Recycled Concrete Structures and Construction at Tongji University, Shanghai. The first part discusses the necessary mechanical and durability properties of recycled concrete with recycled aggregate as well as recycled powder focusing on workability, strength, Poisson’s ratio, stress-strain behaviour along with carbonation, chloride penetration shrinkage and creep. The second part throws light on the elements and structures made with recycled aggregate concrete (RAC), discussing the behaviours of RAC components and structures.

Abstract
The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. With international groups volunteering to join, the "APASL ACLF Research Consortium (AARC)" was formed in 2012, which continued to collect prospective ACLF patient data. Based on the prospective data analysis of nearly 1400 patients, the AARC consensus was published in 2014. In the past nearly four-and-a-half years, the AARC database has been enriched to about 5200 cases by major hepatology centers across Asia. The data published during the interim period were carefully analyzed and areas of contention and new developments in the field of ACLF were prioritized in a systematic manner. The AARC database was also approached for answering some of the issues where published data were limited, such as liver failure grading, its impact on the 'Golden Therapeutic Window', extrahepatic organ dysfunction and failure, development of sepsis, distinctive features of acute decompensation from ACLF and pediatric ACLF and the issues were analyzed. These initiatives concluded in a two-day meeting in October 2018 at New Delhi with finalization of the new AARC consensus. Only those statements, which were based on evidence using the Grade System and were unanimously recommended, were accepted. Finalized statements were again circulated to all the experts and subsequently presented at the AARC investigators meeting at the AASLD in November 2018. The suggestions from the experts were used to revise and finalize the consensus. After detailed deliberations and data analysis, the original definition of ACLF was found to withstand the test of time and be able to identify a homogenous group of patients presenting with liver failure. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information and areas requiring future studies are presented here.

Abstract
Extended X-ray absorption fine structure (EXAFS) spectroscopy is a premiere method for analysis of the structure and structural transformation of nanoparticles. Extraction of analytical information about the three-dimensional structure and dynamics of metal-metal bonds from EXAFS spectra requires special care due to their markedly non-bulk-like character. In recent decades, significant progress has been made in the first-principles modeling of structure and properties of nanoparticles. In this review, we summarize new approaches for EXAFS data analysis that incorporate particle structure modeling into the process of structural refinement.

Abstract
Streptococcus suis is an important pathogen in pigs and can also cause severe infections in humans. However, little is known about proteins associated with cell growth and pathogenicity of S. suis. In this study, a guanosine triphosphatase (GTPase) MnmE homolog was identified in a Chinese isolate (SC19) that drives a tRNA modification reaction. A mnmE deletion strain (ΔmnmE) and a complementation strain (CΔmnmE) were constructed to systematically decode the characteristics and functions of MnmE both in vitro and in vivo studies via proteomic analysis. Phenotypic analysis revealed that the ΔmnmE strain displayed deficient growth, attenuated pathogenicity, and perturbation of the arginine metabolic pathway mediated by the arginine deiminase system (ADS). Consistently, tandem mass tag -based quantitative proteomics analysis confirmed that 365 proteins were differentially expressed (174 up- and 191 down-regulated) between strains ΔmnmE and SC19. Many proteins associated with DNA replication, cell division, and virulence were down-regulated. Particularly, the core enzymes of the ADS were significantly down-regulated in strain ΔmnmE. These data also provide putative molecular mechanisms for MnmE in cell growth and survival in an acidic environment. Therefore, we propose that MnmE, by its function as a central tRNA-modifying GTPase, is essential for cell growth, pathogenicity, as well as arginine metabolism of S. suis.

Abstract
Tetramethylpyrazine (TMP) is a biologically active ingredient, which is isolated from a popularChinese medicinal plant. It has been used effectively to treat ischemic heart problems, cerebrovascular and thrombotic vascular diseases. This study was designed to evaluate the effect of TMP on calciumsensing receptors in pulmonary artery smooth muscle in chickens. For this purpose forty day-old chicks were distributed into five groups: the control group, the hypoxia group (kept under low Oxygen treatment), and TMP groups (kept under low Oxygen treatment along with treatment of different concentrations of TMP). The pulmonary artery smooth muscle cells were also cultured on 6-well plates in high glucose culture medium and divided into the same five groups. We used in vivo and in vitro study models by applying immunohistochemistry, RT-qPCR assay and Western blotting analysis. Our results showed that pre-incubation with hypoxia markedly stimulated the activation of calcium-sensing receptor (CaSR) in pulmonary artery smooth muscle cells (PASMCs). The TMP decreased the mRNA and protein levels of CaSR. Treatment with TMP clearly inhibited the activation of all CaSR in a dose-dependent manner. Our data demonstrated that TMP can down-regulate the expression of CaSR. Therefore, these findings provide a new target to treat pulmonary arterial hypertension (PAH) under hypoxic conditions.

Abstract
BACKGROUND AND AIM There is limited data on predictors of acute kidney injury in acute on chronic liver failure. We developed a PIRO model (Predisposition, Injury, Response, Organ failure) for predicting acute kidney injury in a multicentric cohort of acute on chronic liver failure patients. PATIENTS AND METHODS Data of 2360 patients from APASL-ACLF Research Consortium (AARC) was analysed. Multivariate logistic regression model (PIRO score) was developed from a derivation cohort (n=1363) which was validated in another prospective multicentric cohort of acute on chronic liver failure patients (n=997). RESULTS Factors significant for P component were serum creatinine[(≥2 mg/dL)OR 4.52, 95% CI (3.67-5.30)], bilirubin [(<12 mg/dL,OR 1) vs (12-30 mg/dL,OR 1.45, 95% 1.1-2.63) vs (≥30 mg/dL,OR 2.6, 95% CI 1.3-5.2)], serum potassium [(<3 mmol/LOR-1) vs (3-4.9 mmol/L,OR 2.7, 95% CI 1.05-1.97) vs (≥5 mmol/L,OR 4.34, 95% CI 1.67-11.3)] and blood urea (OR 3.73, 95% CI 2.5-5.5); for I component nephrotoxic medications (OR-9.86, 95% CI 3.2-30.8); for R component,Systemic Inflammatory Response Syndrome,(OR-2.14, 95% CI 1.4-3.3); for O component, Circulatory failure (OR-3.5, 95% CI 2.2-5.5). The PIRO score predicted acute kidney injury with C-index of 0.95 and 0.96 in the derivation and validation cohort. The increasing PIRO score was also associated with mortality (P<.001) in both the derivation and validation cohorts. CONCLUSIONS The PIRO model identifies and stratifies acute on chronic liver failure patients at risk of developing acute kidney injury. It reliably predicts mortality in these patients, underscoring the prognostic significance of acute kidney injury in patients with acute on chronic liver failure.

Abstract
BACKGROUND AND AIMS Acute-on-chronic liver failure (ACLF) is a progressive disease associated with rapid clinical worsening and high mortality. Early prediction of mortality and intervention can improve patient outcomes. We aimed to develop a dynamic prognostic model and compare it with the existing models. METHODS A total of 1402 ACLF patients, enrolled in the APASL-ACLF Research Consortium (AARC) with 90-day follow-up, were analyzed. An ACLF score was developed in a derivation cohort (n = 480) and was validated (n = 922). RESULTS The overall survival of ACLF patients at 28 days was 51.7%, with a median of 26.3 days. Five baseline variables, total bilirubin, creatinine, serum lactate, INR and hepatic encephalopathy, were found to be independent predictors of mortality, with AUROC in derivation and validation cohorts being 0.80 and 0.78, respectively. AARC-ACLF score (range 5-15) was found to be superior to MELD and CLIF SOFA scores in predicting mortality with an AUROC of 0.80. The point scores were categorized into grades of liver failure (Gr I: 5-7; II: 8-10; and III: 11-15 points) with 28-day cumulative mortalities of 12.7, 44.5 and 85.9%, respectively. The mortality risk could be dynamically calculated as, with each unit increase in AARC-ACLF score above 10, the risk increased by 20%. A score of ≥11 at baseline or persisting in the first week was often seen among nonsurvivors (p = 0.001). CONCLUSIONS The AARC-ACLF score is easy to use, dynamic and reliable, and superior to the existing prediction models. It can reliably predict the need for interventions, such as liver transplant, within the first week.

Abstract
Outbreaks of highly pathogenic porcine reproductive and respiratory syndrome virus (HP-PRRSV) have led to large economic losses in China. The attenuated vaccine (HP-PRRSV JXA1-R) was used to control HP-PRRSV. However, in recent years, co-infection with classical PRRSV (C-PRRSV), HP-PRRSV, and/or HP-PRRSV JXA1-R has been increasing in China, resulting in a significant impact on PRRSV diagnostics and management. To facilitate rapid discrimination of HP-PRRSV JXA1-R from HP-PRRSV and C-PRRSV, a multiplex RT-PCR assay for the visual detection of HP-PRRSV JXA1-R, HP-PRRSV, and C-PRRSV was established and evaluated with reference PRRSV strains and clinical samples. Primer specificities were evaluated with RNA/DNA extracted from 10 viral strains, and our results revealed that the primers had a high specificity for PRRSV. The assay sensitivity was 24 copies/μL for PRRSVs. A total of 516 serum samples were identified, of which 12.21% (63/516) were HP-PRRSV-positive, 2.33% (12/516) were HP-PRRSV JXA1-R-positive, and 1.16% (6/516) were C-PRRSV-positive, respectively, which was completely consistent with the sequencing method. The high specificity, sensitivity, and reliability of the multiplex RT-PCR assay described in this study indicate that it is useful for the rapid and differential diagnosis of HP-PRRSV JXA1-R, HP-PRRSV, and C-PRRSV.

Abstract
Altered microRNA (miRNAs) expression has been reported in chordoma which has been considered as an important and complex disease. The study aims to explore the mechanism of miR-31-5p in chordoma in vitro. We firstly verified miR-31-5p level after mimics transfection using real-time PCR and found over-expressed miR-31-5p could inhibit cell growth and invasive ability, while induce cell apoptosis in vitro as detected by CCK8 assay, flow cytometry assay and transwell assay, respectively. Based on prediction result in silico, we validated the target gene C-met using dual-luciferase assay and detected the alternation of miR-31-5p as evidence. Using recombinant plasmid, we also found over-expressed c-Met could reduce the effect of over-expressed miR-31-5p on cell growth, cell cycle change, cell apoptosis and invasive ability as detected by CCK8 assay, flow cytometry assay and transwell assay respectively. Meanwhile, it was also appeared that the PI3K/AKT signaling pathway relevant proteins had alternation through WB assays in U-CH1 cells with treatment of miR-31-5p and c-met recombinant plasmid. miR-31-5p may play a protective role in chordoma patients by targeting c-met and then activating PI3K/AKT signaling pathway which suggested that alterations of miR-31-5p might be a useful biomarker and a potential therapy for early detection of chordoma as disease-related molecular and genetic changes.

Abstract
BACKGROUND Although both obesity and hypertension are known risk factors for disability, the joint association of obesity and hypertension with risk of disability is unknown. This paper is aim to examine the joint association of obesity and hypertension with risk of disability. METHODS Cross-sectional study with 8060 elderly community-dwelling individuals participating in the survey initiated by Shanghai Health and Family Planning Commission from March to September 2013. Obesity was measured using the body mass index (BMI) in World Health Organization (WHO) Asia criteria. Hypertension, based on the doctor's diagnosis, was obtained through face-to-face interview. Disability was measured using the self-reported physical self-maintenance scale (PSMS) and the instrumental activities of daily living (IADL) scale developed by Lawton and Brody. RESULTS A total of 8.97% of participants reported ADL disability, and 15.18% for IADL disability. After adjusting social demographics and chronic conditions, the risk of ADL disability was progressively greater in obese persons with hypertension (OR=1.40, 95% CI=1.05-1.89), underweight persons without hypertension (OR=2.05, 95% CI=1.29-3.25), and underweight persons with hypertension (OR=2.14, 95% CI=1.36-3.36). For IADL disability, only underweight persons with hypertension were significantly associated (OR=1.65, 95% CI=1.23-2.21). CONCLUSIONS Low or extremely high BMI, independent of its metabolic consequences, is a risk factor for disability among the elderly. Simple hypertension wasn't significantly associated with disability. In addition, having hypertension significantly increased the risk of ADL disability in obese individuals and IADL disability in underweight individuals.

Abstract
The chronic hepatitis C (CHC) cohort in the United States is getting older. Elderly patients with CHC may be at a high risk of cirrhosis and hepatocellular carcinoma (HCC), but also other nonhepatic comorbidities that negatively impact their likelihood of receiving or responding to antiviral treatment. There is little information on the clinical epidemiology or outcomes of CHC and its treatment in the elderly. We conducted a retrospective cohort study of 1 61 744 patients with a positive Hepatitis C virus RNA in the Veterans Health Administration Hepatitis C Clinical Case Registry to examine the association between age subgroups (20-49, 50-64, 65-85 years) and risk of cirrhosis, HCC or death using Cox proportional hazards models. We also examined the effect of treatment with a sustained viral response (SVR) on these outcomes in each age subgroup. The age distribution was 36.8% 20- to 49-year-olds, 57.6% 50- to 64-year-olds and 5.6% 65- to 85-year-olds (i.e. elderly). Risk of cirrhosis, HCC and death was significantly elevated in elderly patients [HR cirrhosis = 1.14 (1.00-1.29), HR HCC = 2.44 (1.99-2.99); HR death 2.09 (1.98-2.22)] compared with younger patients. The incidence of HCC was than 8.4 per 1000 PY in the elderly compared with 2.6 per 1000 PY and 5.7 per 1000 PY, among the 20-49 and 50-64 age groups, respectively. Elderly patients were significantly less likely to receive antiviral treatment (3.8% vs 14.8% and 19.1%, P < 0.0001), but among those who received treatment SVR was not different among the age groups (33.5% vs 33.2% and 32.1%). In an analysis limited to those who received treatment, SVR compared to treatment receipt with no SVR was associated with a reduction in risk of developing cirrhosis (HR = 0.34; 0.18-0.66) and HCC (HR = 0.60; 0.22-1.61) and all-cause mortality risk (HR = 0.52, 0.33-0.82). Elderly patients with CHC are more likely to develop HCC than younger patients but have traditionally received less antiviral treatment than younger patients. However, receipt of curative treatment is associated with a benefit in reducing cirrhosis, HCC and overall mortality, irrespective of age.

Abstract
Our previous studies have demonstrated that inhibition of glycogen synthase kinase 3β (GSK3β) activity protects mice from acute liver failure (ALF), whereas its protective and regulatory mechanism remains elusive. Autophagy is a recently recognized rudimentary cellular response to inflammation and injury. The aim of the present study was to test the hypothesis that inhibition of GSK3β mediates autophagy to inhibit liver inflammation and protect against ALF. In ALF mice model induced by D-galactosamine (D-GalN) and lipopolysaccharide (LPS), autophagy was repressed compared with normal control, and D-GalN/LPS can directly induce autophagic flux in the progression of ALF mice. Autophagy activation by rapamycin protected against liver injury and its inhibition by 3-methyladenine (3-MA) or autophagy gene 7 (Atg7) small interfering RNA (siRNA) exacerbated liver injury. The protective effect of GSK3β inhibition on ALF mice model depending on the induction of autophagy, because that inhibition of GSK3β promoted autophagy in vitro and in vivo, and inhibition of autophagy reversed liver protection and inflammation of GSK3β inhibition. Furthermore, inhibition of GSK3β increased the expression of peroxisome proliferator-activated receptor α (PPARα), and the downregulated PPARα by siRNA decreased autophagy induced by GSK3β inhibition. More importantly, the expressions of autophagy-related gene and PPARα are significantly downregulated and the activity of GSK3β is significantly upregulated in liver of ALF patients with hepatitis B virus. Thus, we have demonstrated the new pathological mechanism of ALF that the increased GSK3β activity suppresses autophagy to promote the occurrence and development of ALF by inhibiting PPARα pathway.

Abstract
BACKGROUND Most clinical practice guidelines recommend screening for HCC in patients with cirrhosis. However, patients with compensated cirrhosis are often asymptomatic and may remain unrecognised for years. AIMS To determine the extent to which cirrhosis is unrecognised in a US Veteran population with HCC, and to evaluate the association between lack of cirrhosis recognition and stage of HCC at diagnosis. METHODS We reviewed the electronic medical records of a random sample of HCC cases diagnosed in the national Veterans Affairs system between 2005 and 2011. We conducted multivariable analyses adjusting for patients' demographics, comorbidity, aetiology of underlying disease and healthcare utilisation including HCC surveillance. RESULTS Of 1201 patients with HCC and cirrhosis, 24.6% had unrecognised cirrhosis prior to HCC diagnosis. Older patients [>65 years, odds ratio (OR) 2.32], African Americans (OR 1.93), patients with alcoholic or NAFLD liver disease (OR 1.69 and 4.77 respectively), HIV (OR 3.02), and fewer comorbidities (Deyo 0 vs. 3, OR 2.42) had significantly higher odds of having unrecognised cirrhosis than comparison groups. Furthermore, patients with unrecognised cirrhosis were 6.5 times more likely to have advanced stage HCC at diagnosis. The effect of cirrhosis recognition on HCC stage remained significant after adjusting for pre-specified covariates (OR 3.37). CONCLUSIONS In one quarter of patients, cirrhosis was unrecognised prior to HCC diagnosis, and this group was significantly more likely to have advanced stage HCC. These findings emphasise the importance of timely evaluation for cirrhosis in at-risk populations as a critical step to improving outcomes for patients with HCC.

Abstract
Although endoplasmic reticulum (ER) stress is critical in various liver diseases, its role in acute-on-chronic liver failure (AoCLF) caused by acute exacerbation of chronic hepatitis B (CHB) is still elusive. This study aimed to analyse ER stress responses in the progression of HBV-related AoCLF. Normal liver tissues (n = 10), liver tissues of CHB (n = 12) and HBV-related patients with AoCLF (n = 19) were used. Electron microscopy of the ultrastructure of the ER was carried out on liver specimens. The gene and protein expression levels of ER stress-related genes were measured. We further analysed the correlation between the expression levels of ER stress-related molecules and liver injury. Electron microscopy identified typical features of the ER microstructure in AoCLF subjects. Among the three pathways of unfolded protein responses, the PKR-like ER kinase and inositol-requiring enzyme 1 signalling pathway were activated in CHB subjects and inactivated in AoCLF subjects, while the activating transcription factor 6 signalling pathway was sustained in the activated form during the progression of AoCLF; the expression of glucose-regulated protein (Grp)78 and Grp94 was gradually decreased in AoCLF subjects compared to healthy individuals and CHB subjects, showing a negative correlation with serum ALT, AST and TBIL; moreover, the ER stress-related apoptosis molecules were activated in the progression of acute exacerbation of CHB. The dysregulated ER stress response may play a complicated role in the pathogenesis of AoCLF, and a severe ER stress response may predict the occurrence of AoCLF caused by acute exacerbation of CHB.

Abstract
Sex-determining region Y box 6 (SOX6) has been described as a tumor-suppressor gene in several cancers. Our previous work has suggested that SOX6 upregulated p21Waf1/Cip1(p21) expression in a p53-dependent manner; however, the underlying mechanism has remained elusive. In this study, we confirmed that SOX6 can suppress cell proliferation in vitro and in vivo by stabilizing p53 protein and subsequently upregulating p21. Co-immunoprecipitation and immunocytofluorescence assays demonstrated that SOX6 can promote formation of the p14ARF-HDM2-p53 ternary complex by promoting translocation of p14ARF (p14 alternate reading frame tumor suppressor) to the nucleoplasm, thereby inhibiting HDM2-mediated p53 nuclear export and degradation. Chromatin immunoprecipitation combined with PCR assay proved that SOX6 can bind to a potential binding site in the regulatory region of the c-Myc gene. Furthermore, we confirmed that SOX6 can downregulate the expression of c-Myc, as well as its direct target gene nucleophosmin 1 (NPM1), and that the SOX6-induced downregulation of NPM1 is linked to translocation of p14ARF to the nucleoplasm. Finally, we showed that the highly conserved high-mobility group (HMG) domain of SOX6 is required for SOX6-mediated p53 stabilization and tumor inhibitory activity. Collectively, these results reveal a new mechanism of SOX6-mediated tumor suppression involving p21 upregulation via the p14ARF-HDM2-p53 axis in an HMG domain-dependent manner.

Abstract
Acute hepatitis C virus (HCV) infection is primarily followed by chronic infection, while spontaneous recovery of HCV infection (SR-HCV) occurs in a minority of those infected. Identification of SR-HCV clinically depends on two combined indicators, persistently undetectable peripheral HCV RNA and positivity for anti-HCV. However, the characteristics of dynamic variation in anti-HCV antibodies in SR-HCV, especially in those patients co-infected with HIV, are still undefined. In this study, a cohort of patients infected with HCV through commercial blood collection practices was studied. We found that the annual decreasing rate of anti-HCV presented a gradually accelerated process in HCV resolvers. However, the variation in the decline of anti-HCV presented a slowly accelerated process within the early decrease stage and a gradually decelerated process within the latter decrease stage. In addition, we deduced that it expended approximately 16 years from natural HCV recovery to undetectable peripheral anti-HCV in HCV resolvers co-infected with HIV, while this time was estimated to be 20 years in SR-HCV without HIV co-infection. Our data indicated that the decay of anti-HCV was accelerated by HIV-related impairment of immune function. The prevalence of HCV infection may be severely underestimated in this large-scale retrospective epidemiologic investigation in an HIV-infected population.

Abstract
The colorectum (late distal colon) is innervated by the sympathetic nervous system, and many colorectal diseases are related to disorders of the sympathetic nervous system. The sympathetic regulation of colorectal ion transport is rarely reported. The present study aims to investigate the effect of norepinephrine (NE) in the normal and catecholamine-depleted condition to clarify the regulation of the sympathetic adrenergic system in ion transport in the rat colorectum. NE-induced ion transport in the rats colorectum was measured by short-circuit current (I(sc)) recording; the expression of beta-adrenoceptors and NE transporter (NET) were quantified by real-time PCR, and western blotting. When the endogenous catecholamine was depleted by reserpine, the baseline I(sc) in the colorectum was increased significantly comparing to controls. NE evoked downward deltaI(sc) in colorectum of treated rats was 1.8-fold of controls. The expression of beta(2)-adrenoceptor protein in the colorectal mucosa was greater than the control, though the mRNA level was reduced. However, NET expression was significantly lower in catecholamine-depleted rats compared to the controls. In conclusion, the sympathetic nervous system plays an important role in regulating basal ion transport in the colorectum. Disorders of sympathetic neurotransmitters result in abnormal ion transport, beta-adrenoceptor and NET are involved in the process.

Abstract
Peroxisome proliferator-activated receptor α (PPARα) has been reported to induce a potent anti-inflammatory response. Autophagy is a recently recognized rudimentary cellular response to inflammation and injury. The aim of the present study was to test the hypothesis that PPARα activation mediates autophagy to inhibit liver inflammation and protect against acute liver failure (ALF). PPARα expression during ALF and the impact of PPARα activation by Wy-14 643 on the hepatic immune response were studied in a D-galactosamine/lipopolysaccharide-induced mouse model. Autophagy was inhibited by 3-methyladenine or small interfering RNA (siRNA) against Atg7. In both the mouse model and human ALF subjects, PPARα was significantly downregulated in the injured liver. PPARα activation by pretreatment with Wy-14 643 protected against liver injury in mice. The protective effect of PPARα activation relied on the suppression of inflammatory mechanisms through the induction of autophagy. This hypothesis is supported by the following evidence: first, PPARα activation suppressed proinflammatory responses and inhibited phosphorylated NF-κBp65, phosphorylated JNK and phosphorylated ERK pathways in vivo. Second, protection by PPARα activation was due to the induction of autophagy because inhibition of autophagy by 3-methyladenine or Atg7 siRNA reversed liver protection and inflammation. Third, PPARα activation directly induced autophagy in primary macrophages in vitro, which protected cells from a lipopolysaccharide-induced proinflammatory response. Here, for the first time, we have demonstrated that PPARα-mediated induction of autophagy ameliorated liver injury in cases of ALF by attenuating inflammatory responses, indicating a potential therapeutic application for ALF treatment.

Abstract
BACKGROUND AND PURPOSE Susceptibility-weighted imaging (SWI) is a high spatial resolution technique that can indirectly demonstrate increased cerebral oxygen extraction. Our aim was to assess whether asymmetric cortical vessel sign (ACVS) on SWI could be associated with early neurological deterioration (END) as well as 90-day unfavorable outcome in patients with acute ischaemic stroke. MATERIALS AND METHODS Consecutive patients with acute middle cerebral artery (MCA) territory infarction were prospectively enrolled. ACVS was defined as more and/or larger vessels with greater signal loss than those in the opposite hemisphere on minimum intensity projection of SWI. The neurofunctional fluctuation during acute phase as well as 90-day outcomes were assessed. A National Institutes of Health Stroke Scale increment ≥2 points and ≥4 points despite standard treatment in the first 72 h after admission was defined as END2 and END4, respectively. RESULTS In all, 572 patients were finally enrolled. ACVS on SWI was present in 39 (6.8%) subjects. Multivariate analysis indicated that ACVS is an independent predictor for END2 [odds ratio (OR) 4.47, 95% confidence interval (CI) 1.99-10.05) and END4 (OR 4.24, 95% CI 1.94-9.23). Furthermore, ACVS also correlates with 90-day unfavorable outcome defined as a modified Rankin Scale score >1 point (OR 2.93, 95% CI 1.15-7.48). Both positive and negative predictive values of ACVS for END2, END4 and 90-day prognosis were reasonable and both could be slightly enhanced as long as patients with contralateral artery stenosis or occlusion were excluded. CONCLUSION In patients with MCA territory acute ischaemic stroke, especially in those without contralateral internal carotid artery/MCA stenosis or occlusion, ACVS might be considered as a neuroimaging predictor for END and unfavorable prognosis.

Abstract
Enterovirus 71 (EV71) infection has a wide variety of clinical manifestations, from no symptoms to fatal disease. Host immune response may be a determinant of disease severity. We investigated the association of polymorphisms in three pattern recognition receptor (PRR) genes-toll-like receptor 3 (TLR3) (rs3775291), retinoic acid-inducible gene I (RIG-I) (rs10813831) and melanoma differentiation-associated gene 5 (MDA5) (rs1990760)-with the severity of EV71 infection. Polymorphisms of candidate genes in 87 EV71-infected patients and 57 asymptomatic controls were detected. Binary logistic regression analysis revealed statistically significant differences in polymorphism of MDA5 (rs1990760) between patients with severe EV71 infection and asymptomatic controls in an additive model (OR 0.424, 95% CI 0.213-0.845, p 0.015) and a dominant model (OR 0.256, 95% CI 0.103-0.635, p 0.003). Polymorphism of MDA5 (rs1990760) (OR 0.399, 95% CI 0.199-0.798, p 0.009) was found to be associated with the severity of EV71 infection with the analysis of ordinal logistic regression. These results indicated the association between MDA5 (rs1990760) polymorphism and an increased risk of a severe EV71 infection in Chinese children, which offers potential for investigating the innate immune mechanism of EV71 infection and identifying at-risk infants, for whom a preventive strategy may reduce the severity of EV71 infection.
