Abstract
OBJECTIVES The objective of this study was to synthesize arginine loaded mesoporous silica nanoparticles (Arg@MSNs), develop a novel orthodontic adhesive using Arg@MSNs as modifiers, and investigate the adhesive performance, antibacterial activity, and biocompatibility. METHODS Arg@MSNs were synthesized by immobilizing arginine into MSNs and characterized using transmission electron microscope (TEM), dynamic light scattering (DLS), and Fourier Transform Infrared Spectrometer (FT-IR). Arg@MSNs were incorporated into Transbond XT adhesive with different mass fraction to form functional adhesives. The degree of conversion (DC), arginine release behavior, adhesive performance, antibacterial activity against Streptococcus mutans biofilm, and cytotoxicity were comprehensively evaluated. RESULTS TEM, DLS, and FT-IR characterizations confirmed the successful preparation of Arg@MSNs. The incorporation of Arg@MSNs did not significantly affect DC and exhibited clinically acceptable bonding strength. Compared to the commercial control, the Arg@MSNs modified adhesives greatly suppressed the metabolic activity and polysaccharide production while increased the biofilm pH values. The cell counting kit (CCK)-8 test indicated no cytotoxicity. CONCLUSIONS The novel orthodontic adhesive containing Arg@MSNs exhibited significantly enhanced antibacterial activities and inhibitory effects on acid production compared to the commercial adhesive without compromising their bonding strength or biocompatibility. CLINICAL SIGNIFICANCE The novel orthodontic adhesive containing Arg@MSNs exhibits potential clinical benefits in preventing demineralization of enamel surfaces around or beneath orthodontic brackets due to its enhanced antibacterial activities and acid-producing inhibitory effects.

Abstract
OBJECTIVE To investigate the effects of parecoxib on postoperative cognitive dysfunction, and serum levels of neuron-specific enolase (NSE) and S100β protein (S100β) in elderly patients undergoing surgery. PATIENTS AND METHODS The retrospective cohort study method was used to collect the clinical data of 94 elderly patients who underwent elective orthopedic and general anesthesia surgery in our hospital from September 2020 to February 2022. 94 patients were divided into the control group (47 cases) and the study group (47 cases), according to different intervention methods. In the study group, 40 mg of parecoxib was injected intravenously into patients 30 min before the induction of anesthesia, and the patients in the control group were given the same dose of normal saline intravenously before the operation. The basic clinical data of the patients were collected. The levels of the indexes before operation and 6 hours after operation were compared between the two groups, including the Montreal Cognitive Scale (MoCA) score, inflammatory factor indicators [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), C-reactive protein (CRP), interleukin-10 (IL-10), interleukin-1β (IL-1β), monocyte chemokine-1 (MCP-1), and inducible nitric oxide synthase (iNOS)], serum cortisol (CORT), beta-amyloid (β-AP), adiponectin (ADP), NSE, and S100β. RESULTS No significant differences in the preoperative MoCA score, TNF-α, IL-6, CRP, IL-10, IL-1β, MCP-1, iNOS, CORT, β-AP, ADP, NSE, and S100β levels were observed between the two groups (p>0.05). The postoperative MoCA score in the study group was significantly higher than that in the control group (p<0.05). The postoperative levels of TNF-α, IL-6, CRP and IL-1β in the study group were significantly lower than those in the control group (p<0.05), and the postoperative levels of IL-10, MCP-1 and iNOS in the study group were significantly higher than those in the control group (p<0.05). CONCLUSIONS Parecoxib can notably inhibit the levels of postoperative inflammatory cytokines, improve neurological dysfunction, and reduce the occurrence of postoperative cognitive dysfunction in patients. The contents of serum NSE and S100β have potential value in the diagnosis of postoperative cognitive dysfunction in elderly patients.

Abstract
The development of human trophoblast stem cells (hTSC) and stem cell-derived trophoblast organoids has enabled investigation of placental physiology and disease and early maternal-fetal interactions during a stage of human pregnancy that previously had been severely restricted. A key shortcoming in existing trophoblast organoid methodologies is the non-physiologic position of the syncytiotrophoblast (STB) within the inner portion of the organoid, which neither recapitulates placental villous morphology in vivo nor allows for facile modeling of STB exposure to the endometrium or the contents of the intervillous space. Here we have successfully established properly-polarized human trophoblast stem cell (hTSC)-sourced organoids with STB forming on the surface of the organoid. These organoids can also be induced to give rise to the extravillous trophoblast (EVT) lineage with HLA-G + migratory cells that invade into an extracellular matrix-based hydrogel. Compared to previous hTSC organoid methods, organoids created by this method more closely mimic the architecture of the developing human placenta and provide a novel platform to study normal and abnormal human placental development and to model exposures to pharmaceuticals, pathogens and environmental insults. Motivation Human placental organoids have been generated to mimic physiological cell-cell interactions. However, those published models derived from human trophoblast stem cells (hTSCs) or placental villi display a non-physiologic "inside-out" morphology. In vivo , the placental villi have an outer layer of syncytialized cells that are in direct contact with maternal blood, acting as a conduit for gas and nutrient exchange, and an inner layer of progenitor, single cytotrophoblast cells that fuse to create the syncytiotrophoblast layer. Existing "inside-out" models put the cytotrophoblast cells in contact with culture media and substrate, making physiologic interactions between syncytiotrophoblast and other cells/tissues and normal and pathogenic exposures coming from maternal blood difficult to model. The goal of this study was to develop an hTSC-derived 3-D human trophoblast organoid model that positions the syncytiotrophoblast layer on the outside of the multicellular organoid.

Abstract
Recently, deep neural network-based cognitive models such as deep knowledge tracing have been introduced into the field of learning analytics and educational data mining. Despite an accurate predictive performance of such models, it is challenging to interpret their behaviors and obtain an intuitive insight into latent student learning status. To address these challenges, this paper proposes a new learner modeling framework named the EAKT, which embeds a structured cognitive model into a transformer. In this way, the EAKT not only can achieve an excellent prediction result of learning outcome but also can depict students' knowledge state on a multi-dimensional knowledge component(KC) level. By performing the fine-grained analysis of the student learning process, the proposed framework provides better explanatory learner models for designing and implementing intelligent tutoring systems. The proposed EAKT is verified by experiments. The performance experiments show that the EAKT can better predict the future performance of student learning(more than 2.6% higher than the baseline method on two of three real-world datasets). The interpretability experiments demonstrate that the student knowledge state obtained by EAKT is closer to ground truth than other models, which means EAKT can more accurately trace changes in the students' knowledge state.

Abstract
Classical swine fever (CSF) and porcine reproductive and respiratory syndrome (PRRS) are responsible for major economic losses and represent a threat to the swine industry worldwide. Routine surveillance serology for CSF and PRRS viruses is critical to maintaining the health status of sow farms in Hunan Province, which is one of the top pig production provinces in China. The aim of our study was to investigate the serological statistics of CSF virus (CSFV) and PRRS virus (PRRSV) in Hunan Province. The cohort serum samples were collected from vaccinated and unvaccinated pigs. Our findings showed that the average rates of CSFV and PRRSV antibody seropositivity were 82.2% (95% CI: 80.1-84.3) and 84.8% (95% CI: 82.5-87.1), respectively, in the immunized group and that these rates were higher than those in the unvaccinated group (58.6% for CSFV and 47.8% for PRRSV). Additionally, the level of CSFV antibody in piglet serum declined gradually with age, whereas PRRSV-specific antibody level increased initially (1 to 2 weeks old) and then declined with age (2 to 4 weeks old). In summary, we investigated the difference in CSFV/PRRSV antibody levels among piglets at various weeks old (1 to 4 weeks) to further establish the duration of maternal immunity in piglets. In addition, routine monitoring of CSFV/PRRSV antibodies in immunized pigs was carried out to evaluate the efficacy of vaccination.

Abstract
Colorectal cancer (CRC) has become one of the top ten malignant tumors with a high incidence rate and mortality. Due to the lack of a good CRC screening program, most of the CRC patients are being transferred at the time of treatment. The conventional treatment cannot effectively improve the prognosis of CRC patients, and the target drugs can significantly prolong the overall survival of patients in the advanced stage. However, the use of single drug may lead to acquired drug resistance and various serious complications. Therefore, combined targeted drug therapy is the main alternative treatment with poor effect of single targeted drug therapy, which has important research significance for the treatment of CRC. Therefore, this study intends to culture CRC cell lines in vitro at the cell level and intervene with the GLP-1 receptor agonist liraglutide. The effects of liraglutide on the PI3K/Akt/mTOR signal pathway and CRC cell proliferation, cycle, migration, invasion, and apoptosis are explored by detecting cell proliferation, cycle, migration, invasion, and apoptosis and the expression of related mRNA and protein. The results showed that liraglutide, a GLP-1 receptor agonist, could block the CRC cell cycle, reduce cell proliferation, migration, and invasion and promote apoptosis by inhibiting the PI3K/Akt/mTOR signal pathway.

Abstract
AbstractStudent cognitive models are playing an essential role in intelligent online tutoring for programming courses. These models capture students’ learning interactions and store them in the form of a set of binary responses, thereby failing to utilize rich educational information in the learning process. Moreover, the recent development of these models has been focused on improving the prediction performance and tended to adopt deep neural networks in building the end-to-end prediction frameworks. Although this approach can provide an improved prediction performance, it may also cause difficulties in interpreting the student’s learning status, which is crucial for providing personalized educational feedback. To address this problem, this paper provides an interpretable cognitive model named HELP-DKT, which can infer how students learn programming based on deep knowledge tracing. HELP-DKT has two major advantages. First, it implements a feature-rich input layer, where the raw codes of students are encoded to vector representations, and the error classifications as concept indicators are incorporated. Second, it can infer meaningful estimation of student abilities while reliably predicting future performance. The experiments confirm that HELP-DKT can achieve good prediction performance and present reasonable interpretability of student skills improvement. In practice, HELP-DKT can personalize the learning experience of novice learners.

Abstract
OBJECTIVE The purpose of this study was to uncover the potential impact of alcohol consumption on the tumorigenesis of colorectal cancer (CRC) and the underlying mechanism. PATIENTS AND METHODS Overall survival was compared in CRC patients either with alcohol consumption or not. Subsequently, a mouse model of CRC was established by azoxymethane (AOM) administration. Tumor number and size were compared in CRC mice fed with Lieber-DeCarli liquid diet or normal diet. At last, pathological differences in cell proliferation, apoptosis, inflammation, and intestinal permeability, in intestines harvested from CRC mice fed with Lieber-DeCarli liquid diet or normal diet were assessed. RESULTS It was found that the prognosis was worse in CRC patients with alcohol consumption. In CRC mice fed with Lieber-DeCarli liquid diet, more tumor tissues were found than those in the controls. Besides, alcohol consumption remarkably impaired intestinal permeability, making it easier for bacteria to invade epithelial cells. Moreover, oral gavage of probiotics markedly improved intestinal permeability and reduced tumor number in CRC mice fed with Lieber-DeCarli liquid diet. CONCLUSIONS Probiotics can inhibit the development of alcohol-induced CRC by protecting intestinal permeability.

Abstract
The aim of traditional designs of pulsed magnets is to keep the von-Mises stress on the midplane less than the ultimate tensile strength of materials. However, recently failed high-field experiments showed that some short circuits occurred at the magnet end, which is most possibly caused by the axial displacement of wires. This indicates that the former design is inadequate and accurate axial mechanical analysis of magnets is necessary. In this paper, a finite element model of pulsed magnets considering interface characteristics is proposed. Both the contact status and interfacial friction between the conductor layers and reinforcements can be accounted for Simulations are conducted with a failed 95 T dual-coil prototype, which was originally designed with the self-developed Pulsed Magnet Design Software (PMDS) software. The simulation results show that all the originally expected separations calculated by the PMDS software disappear due to the compression. This makes the calculated maximal von-Mises stress of the inner four reinforcement layers about 600 MPa less than the former designs. The influence of the interfacial friction is also presented. Besides, the simulations show that the maximum axial displacement at the magnet end is up to 8 mm at the designed peak field, which is deadly to the insulations. Hence, we suggest that the axial displacement at the magnet end should also be one design objective of pulsed magnets. At last, the factors affecting the axial displacement are analyzed.

Abstract
Objective: To analyze the differences of clinical characteristics and outcomes between relapsing and monophasic patients with anti-leucine-rich glioma-inactivated 1 (anti-LGI1) encephalitis. Methods: Medical records of confirmed anti-LGI1 encephalitic patients who underwent immunotherapy were retrospectively collected from January 2015 to January 2019 in the first affiliated hospital of Zhengzhou University. Clinical data, treatment methods, duration of treatment and outcomes were analyzed between the relapsing and monophasic groups. Results: Among the 33 anti-LGI1 encephalitic patients, there were 12 and 21 cases in the relapsing and monophasic groups, respectively. No difference was found in age, sex, precipitating factors, intensive care unit (ICU) admission, symptoms and modified Rankin Scale (mRS) score in the acute phase (P>0.05). As to the lab test and image examination, no statistic difference was found in serum and cerebral spinal fluid (CSF) positive rate, hyponatremia, abnormal rate of electrocardiogram (ECG), electroencephalogram (EEG), CSF and magnetic resonance imaging (MRI) and lesion locations (P>0.05). No difference was found in time to diagnose the disease between the 2 groups (P>0.05). The median immunotherapy period was 102.5 days in relapsing group and 194.0 days in monophasic group, with a statistic difference (P=0.001). No patients had bad outcomes in the monophasic group at the last follow-up, while 6 patients had poor outcomes in the relapsing group (4 patients died). The patients in relapsing group had a worse prognosis compared to those in the monophasic group (P=0.007). Conclusions: Relapse is common in anti-LGI1 encephalitis. Patients in the relapsing group received a shorter term of immunotherapy and had worse outcomes than those in the monophasic group.

Abstract
During operation, the acoustic signal of the drum shearer contains a wealth of information. The monitoring or diagnosis system based on acoustic signal has obvious advantages. However, the signal is challenging to extract and recognize. Therefore, this paper proposes an approach for acoustic signal processing of a shearer based on the parameter optimized variational mode decomposition (VMD) method and a clustering algorithm. First, the particle swarm optimization (PSO) algorithm searched for the best parameter combination of the VMD. According to the results, the approach determined the number of modes and penalty parameters for VMD. Then the improved VMD algorithm decomposed the acoustic signal. It selected the ideal component through the minimum envelope entropy. The PSO was designed to optimize the clustering analysis, and the minimum envelope entropy of the acoustic signal was regarded as the feature for classification. We then use a shearer simulation platform to collect the acoustic signal and use the approach proposed in this paper to process and classify the signal. The experimental results show that the approach proposed can effectively extract the features of the acoustic signal of the shearer. The recognition accuracy of the acoustic signal was high, which has practical application value.

Abstract
An interlaboratory study was conducted to evaluate a method for the determination of campesterol, stigmasterol, and beta-sitosterol in saw palmetto raw materials and dietary supplements at levels >1.00 mg/100 g based on a 23 g sample. Test samples were saponified at high temperature with ethanolic KOH solution. The unsaponifiable fraction containing phytosterols (campesterol, stigmasterol, and beta-sitosterol) was extracted with toluene. Phytosterols were derivatized to trimethylsilyl ethers and then quantified by gas chromatography with hydrogen flame ionization detection. Twelve blind duplicates, one of which was fortified, were successfully analyzed by 10 collaborators. Recoveries were obtained for the sample that was fortified. The results were 99.8, 111, and 111% for campesterol, stigmasterol, and beta-sitosterol, respectively. For repeatability, the relative standard deviation (RSDr) ranged from 3.93 to 17.3% for campesterol, 3.56 to 22.7% for stigmasterol, and 3.70 to 43.9% for beta-sitosterol. For reproducibility, the RSDR ranged from 7.97 to 22.6%, 0 to 26.7%, and 5.27 to 43.9% for campesterol, stigmasterol, and beta-sitosterol, respectively. Overall, the Study Director approved 5 materials with acceptable HorRat values for campesterol, stigmasterol, and beta-sitosterol ranging from 1.02 to 2.16.

Abstract
Objective: To investigate the changes of surgical invitations on necrotizing pancreatitis in recent 14 years by reviewing single center data. Methods: One thousand and eighty patients with necrotizing pancreatitis who received surgical invitation were involved in the study.All the patients were treated at Department of Pancreatic Surgery,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2005 to December 2018. Six hundred and seventy-eight were males and 402 were females. The median (range) age of the study patients was 45 (20-76) years.The etiology of the disease was related to cholelithiasis in 335 cases(31.02%), hyperlipemia in 302 cases(27.96%), alcohol in 226 cases(20.93%), endoscopic retrograde cholangiopancreatography in 28 cases(2.59%), pregnancy in 50 cases(4.63%), idiopathic factors in 72 cases(6.67%) and other causes in 67 cases(6.20%). The patients were divided into two groups according to the time of admission. Group 1 included 1 475 patients that admitted from January 2005 to December 2010, and group 2 included 1 539 patients that admitted from January 2011 to December 2018. The surgical interventions, morbidity and mortality of the two group were compared, and χ(2) test was used for the statistical test. Results: Two hundred and sixty-six among the 1 080 cases were treated with drainage procedures because of the pseudocyst.One hundred and seventy-five drainage procedures were performed between January 2005 and December 2018, which account for 11.87%(175 /1 475) of all patients of necrotizing pancreatitis; 91 drainage procedures were performed between January 2011 and December 2018,which account for 5.91%(91/1 539) of all patients of necrotizing pancreatitis. Eight hundred and fourteen cases received surgical intervention for infection of necrotizing tissues. Of these cases, 410 cases received percutaneous catheter drainage(PCD) of retroperitoneal fluid or residual infection. Debridement of necrotic tissues was performed on 756 cases. Of these cases, 32 cases received minimal invasive retroperitoneal debridement with/without denotes video assistant,4 cases received transluminal endoscopic debridement, 21 cases received laparoscopic debridement, and 709 cases received open laparotic debridement.Three hundred and sixty-five cases were admitted to our institute during January 2005 to December 2010, and the other 391 cases were admitted to our institute from January 2011 to December 2018. Of the first period, all debridement were performed with open laparotic procedures. Of the second period,debridement were performed with open laparotic procedures and minimal invasive procedures. The average times of surgical invasion, morbidity of principal local complications and mortality of the two periods were 1.27 and 1.34,28.22%(103/365) and 29.92%(117/346),and 6.03%(23/365) and 6.91%(27/346), respectively. Conclusions: Minimal invasive procedures can be considered for debridement in patients with necrotizing pancreatitis in some selected conditions.The involvements of minimal invasive procedures in treatment of necrotizing pancreatitis don't decrease the morbidity of principal local complications and mortality in recent years. Rational surgical procedures and appropriate surgical timing are the keys to improve the efficacy of necrotizing pancreatitis.

Abstract
OBJECTIVE Detecting a single serum marker, such as Golgi protein 73 (GP73) or alpha-fetoprotein (AFP), may not meet the requirements for the early diagnosis of hepatocellular carcinoma (HCC) due to low sensitivity and specificity. Therefore, this study aimed to develop a simultaneous multiplex assay of GP73 and AFP. PATIENTS AND METHODS Anti-human GP73- and AFP-coupled microsphere beads and biotin-labeled detectable antibodies were prepared to develop a multiplex assay of GP73 and AFP using the Luminex xMAP technology. The assay was evaluated for cross-reactivity, standard curve, sensitivity, range of detection, and precision. Additionally, the assay was used to determine the levels of serum GP73 and AFP in healthy controls and patients with chronic hepatitis, liver cirrhosis, and HCC. RESULTS The multiplex assay was successfully developed to simultaneously detect GP73 and AFP without cross-reactivity. The sensitivity for GP73 detection was 0.215 ng/mL and that for AFP detection was 0.666 ng/mL. The ranges of GP73 and AFP detection were 0.98-861.08 ng/mL and 2.01-1848.73 ng/mL, respectively. The intra- and inter-assay coefficients of variation (CVs) were <10%, indicating good precision, with recovery rates of 75-125%. The levels of serum GP73 in healthy controls, chronic hepatitis patients, liver cirrhosis patients, and HCC patients were 61.64 ± 30.60 ng/mL, 208.4 ± 99.42 ng/mL, 183.7 ± 82.78 ng/mL, and 214.1 ± 160.5 ng/mL, respectively. The levels of serum AFP in healthy controls, chronic hepatitis patients, liver cirrhosis patients, and HCC patients were 24.87 ± 14.52 ng/mL, 134.4 ± 216.5 ng/mL, 66.45 ± 133.4 ng/mL, and 891.4 ± 1278 ng/mL, respectively. The receiver operating characteristic (ROC) results showed that the area under the curves (AUC) for the combination of GP73 and AFP was 0.972, which was larger than the AUC for each marker. The sensitivity and specificity of the combined detection of GP73 and AFP for the diagnosis of HCC were 90.91% and 98.86%, respectively. The multiplex assay demonstrated a good correlation with enzyme-linked immunosorbent assay (ELISA), with correlation coefficients of 0.818 and 0.982 for GP73 (p<0.001) and AFP (p<0.001), respectively. CONCLUSIONS A multiplex assay for the simultaneous detection of GP73 and AFP with high sensitivity and accuracy was developed for the diagnosis of HCC. This assay may provide a reliable reference for the early diagnosis of HCC.

Abstract
Whole electrocardiogram (ECG) waveform analysis is a technique for evaluating aggregate arrhythmic risks of drugs. In this paper, we propose methods for exploring changes to ECG morphology due to drug effects using Gaussian model parameters, and predict patient specific post-drug ECG based on pre-drug ECG. We evaluate the proposed methods using clinical ECG recordings from subjects under the effect of anti-arrhythmic drugs Dofetilide, Quinidine, Ranolazine, and Verapamil, from the ECGRVDQ database on PhysioNet. Paired-sample t-test p-values (>0.05) suggest the proposed method can achieve similar results when compared to expert annotated J to Tpeak and Tpeak to Tend intervals for all four drug states. We employed a leave-one-out cross validation strategy to train the prediction model and produce the results. Mean Pearson correlations between all predicted and recorded post-drug waveform morphologies for all drug states across both the vector magnitude lead and Lead II is 0.94±0.05, with p-values <0.01 for all predictions; indicating significant predictions. Parameters from ECG models with Gaussian basis can be used to calculate clinically useful information and to capture or predict changes in cardiac signals due to drug effects.

Abstract
Background Patient education materials (pems) are frequently used to help patients make cancer screening decisions. However, because pems are typically developed by experts, they might inadequately address patient barriers to screening. We co-created, with patients, a prostate cancer (pca) screening pem, and we compared how the co-created pem and a pem developed by experts affected decisional conflict and screening intention in patients. Methods We identified and used patient barriers to pca screening to co-create a pca screening pem with patients, clinicians, and researchers. We then conducted a parallel-group randomized controlled trial with men 40 years of age and older in Ontario to compare decisional conflict and intention about pca screening after those men had viewed the co-created pem (intervention) or an expert-created pem (control). Participants were randomized using dynamic block randomization, and the study team was blinded to the allocation. Results Of 287 participants randomized to exposure to the co-created pem, 230 were analyzed, and of 287 randomized to exposure to the expert-created pem, 223 were analyzed. After pem exposure, intervention and control participants did not differ significantly in Decisional Conflict Scale scores [mean difference: 0.37 ± 1.23; 95% confidence interval (ci): -2.05 to 2.79]; in sure (Sure of myself, Understand information, Risk-benefit ratio, or Encouragement) scores (odds ratio: 0.75; 95% ci: 0.52 to 1.08); or in screening intention (mean difference: 0.09 ± 0.08; 95% ci: -0.06 to 0.24]). Conclusions The effectiveness of the co-created pem did not differ from that of the pem developed by experts. Thus, pem developers should choose the method that best fits their goals and resources.

Abstract
The peptide components of defatted walnut ( Juglans regia L.) meal hydrolysate (DWMH) remain unclear, hindering the investigation of biological mechanisms and exploitation of bioactive peptides. The present study aims to identify the peptide composition of DWMH, followed by to evaluate in vitro antioxidant effects of selected peptides and investigate mechanisms of antioxidative effect. First, more than 1 000 peptides were identified by de novo sequencing in DWMH. Subsequently, a scoring method was established to select promising bioactive peptides by structure based screening. Eight brand new peptides were selected due to their highest scores in two different batches of DWMH. All of them showed potent in vitro antioxidant effects on H2O2-injured nerve cells. Four of them even possessed significantly stronger effects than DWMH, making the selected bioactive peptides useful for further research as new bioactive entities. Two mechanisms of hydroxyl radical scavenging and ROS reduction were involved in their antioxidative effects at different degrees. The results showed peptides possessing similar capacity of hydroxyl radical scavenging or ROS reduction may have significantly different in vitro antioxidative effects. Therefore, comprehensive consideration of different antioxidative mechanisms were suggested in selecting antioxidative peptides from DWMH.

Abstract
Background Immunoglobulin A nephropathy (IgAN), membranous nephropathy (MN) and minimal-change disease (MCD) are three common types of glomerulonephritis in China. Pathological diagnosis based on renal biopsy is the criterion and the golden standard for diagnosing the sub-types of primary or secondary glomerulonephritis. Immunoglobulin and complements might be used in the differential diagnosis of glomerulonephritis without renal biopsies. However, the relationship between IF intensities of immune proteins and the corresponding serum levels remained unclear, and seldom studies combine histopathological examination results and blood tests together for a predictive purpose. This study was considered as a pilot study for integrating histopathological indicators into serum parameters for exploring the relationship of IF intensity and serum values of immunoglobulin and complement, and for screening and investigating effective indicators inIgAN, MN and MCD. Methods Renal tissue immunofluorescence (IF) intensity grades and serum levels of immunoglobulin and complements (IgG, IgA, IgM, C3 and C4) were retrospectively analyzed in 236 cases with IgAN, MN or MCD. IF grades were grouped as negative (−), positive (+) or strong positive (++) with both high and low magnification of microscope. Other serum indicators such as urea nitrogen (BUN), creatinine (Crea) and estimated glomerular filtration rate (eGFR) were also evaluated among the groups. Results There were difference in IgA, IgG and C3 IF intensity grades among IgAN, MN and MCD groups (p = 9.82E-43, 4.60E-39, 7.45E-15, respectively). Serum values of BUN, Crea, eGFR, IgG, IgA, IgM and C4 showed difference in three groups (BUN: p = 0.045, Crea: p = 3.45E-5, eGFR: p = 0.005, IgG: p = 1.68E-14, IgA: p = 9.14E-9, IgM: p = 0.014, C4: p = 0.026). eGFR had the trend to decrease with enhanced IgA IF positive grades (p = 8.99E-4); Crea had trends to decrease with both enhanced IgA and IgG IF intensity grades (p = 2.06E-6, 2.94E-5, respectively). In all subjects, serum IgA levels was inversely correlated with eGFR(r = − 0.216, p = 0.001) and correlated with Crea levels(r = 0.189, p = 0.004); serum IgG and Crea showed no correlation which were discordance with inverse correlation of IgG IF grade and Crea(r = 0.058,p = 0.379). IgG serum level was inverse correlated with its IF grades (p = 3.54E-5, p = 7.08E-6, respectively); C3 serum levels had significantly difference between Neg and positive (+) group (p = 0.0003). IgA serum level was positive correlated with its IF grades (Neg-(+): p = 0.0001; (+)-(++): p = 0.022; Neg-(++): p = 2.01E-10). After matching comparison among C3 groups, C3 Neg. group and C3 ++ group had difference (*p = 0.017). C4 had all negative IF expression in all pathological groups. In IgAN subjects, there were statistical differences of serum C3 levels between its pathological Neg and positive (+) group(p = 0.026), and serum IgA levels showed difference between IgA pathological positive(+) and (++)(p = 0.007). In MN subjects, sIgG levels showed difference between IgG pathological IF grade positive (+) and (++)(p = 0.044); serum C3 levels showed difference between C3 pathological IF grade Neg and positive(+)(p = 0.005); and serum IgA levels showed difference between Neg and positive(+)(p = 0.040). In IgAN, eGFR showed serum IgA levels had significant differences among groups (p = 0.007) and had increasing trend with enhanced its IF grades(Ptrend = 0.016). There were also difference between IgG group Neg and positive (+) (p = 0.005, Ptrend = 0.007) in IgAN. In MN, serum IgG levels had significant differences among IF groups (p = 0.034) and had decreasing trend with its enhanced IF grades (Ptrend = 0.014). Serum C3 concentrations also were found distinctive among IF groups (p = 0.016) and had in inverse correlation with its enhanced IF grades (Ptrend = 0.004). Discussion Our research cross contrasts several immunoprotein IF intensities and relevant serum levels in three kinds of primary glomerular nephritis, and finally acquired helpful results for understanding the relationships between pathological presentation and serological presentation of immunoproteins in kidney diseases. Furthermore, this pilot study is offering a possible method for the analysis of combination of pathology and serology. Conclusion Different pathological types of nephritis presented different expression patterns of immunoglobulin and complement, especially IgA and IgG, which suggested different pathogenesis involved in the development of IgAN and MN. Furthermore, either in tissue or in serum, increased IgA level was closely related with renal function in all of the patients.

Abstract
In late 2011, a variant pseudorabies virus (vPRV) emerged in Bartha-K61-vaccinated pig herds, resulting in high morbidity and mortality of piglets in China. Since 2013, the autopsy lesions, histological examinations, virus isolation, phylogenetic analysis and selection pressure analysis of the gE gene of vPRV were recorded for 395 clinical cases, and 5,033 pig serum samples were detected by PRV gE-coated enzyme-linked immunosorbent assay. The major clinical symptoms were abortion in pregnant sows, fatal neurological signs in piglets and respiratory disease in growing pigs. Necrotic splenitis, hepatitis and lymphadenitis, haemorrhagic nephritis and non-suppurative encephalitis were observed by histopathological examination. Typical eosinophilic inclusion bodies were found in the nuclei of liver cells. Using PCR, 110 samples among 395 clinical cases tested positive for the gE gene. Fifteen vPRV strains were isolated and confirmed by sequencing and phylogenetic analysis of the gE gene. The strains shared 97.1%-99.9% nucleotide (nt) and 96.6%-99.5% amino acid (aa) homology with PRV reference strains. Selection pressure analysis showed that one site in the codons of glycoprotein E was under positive selection. Of the 5,033 serum samples, 2,909 were positive by ELISA for a positive rate of 57.8%. These results showed that vPRV was still prevalent in Shandong Province, indicating severe PRV infectious pressure. The preparation of new vaccines against PRV is extremely urgent.

Abstract
Objective The objective of this article is to examine the quality, content, and readability of information and resources in the English language and accessible on the internet by pediatric patients with systemic lupus erythematosus (SLE) and their families in North America. Methods Keywords relevant to SLE were generated by an undergraduate student, a first-year medical student, and a third-year pediatric resident, and a search was conducted across five commonly used search engines. Quality of information found was evaluated independently by an undergraduate student, a graduate student, a first-year medical student, and a third-year pediatric resident using the DISCERN tool. Two pediatric rheumatologists assessed website accuracy and completeness. Readability of websites was determined using the Flesch-Kincaid grade level and Reading Ease score. Results Out of 2000 websites generated in the search, only 34 unique websites met inclusion criteria. Only 16 of these websites had DISCERN scores above 50% (fair quality). Overall quality of website information was fair with mean ±standard deviation (SD) DISCERN quality score of 44 ± 7 (range: 30-56). Only nine websites of 34 had DISCERN scores above 50 (>66%, indicating greater quality) and were further assessed for completeness. Flesch-Kincaid grade level was 11 ± 1 (mean±SD) and reading ease score was 39 ± 10 (mean±SD, range of 11-61). Conclusion Our study highlights the need for more complete, readable information regarding the unique needs of pediatric patients with childhood-onset SLE and their families.

Abstract
The cotton aphid, Aphis gossypii, is one of the most economically important agricultural pests worldwide as it is polyphagous and resistant to many classes of insecticides. Overexpression of the cytochrome P450 monooxygenase (P450) CYP6DA2 has previously been found to be associated with gossypol and spirotetramat tolerance in the cotton aphid. In the present study, the elements located in the promoter region (-357:-343; -250:-241; -113:-104) of CYP6DA2 were shown to control promoter activity, and gossypol induction was observed. We hypothesized that the expression of CYP6DA2 is subject to transcriptional regulation. To investigate the underlying mechanism, we assessed two transcription factors, aryl hydrocarbon receptor (AhR) and aryl hydrocarbon receptor nuclear translocator (ARNT), and found that the abundance of AhR was highly correlated with CYP6DA2 abundance. RNA interference of AhR or ARNT significantly decreased the levels of the target gene as well as those of its counterpart, and both dramatically repressed CYP6DA2 expression. Cotransfection of the ARNT, AhR, or AhR plus ARNT and CYP6DA2 promoter constructs elevated CYP6DA2 promoter activity, with the AhR plus ARNT cotransfection being the most effective. Thus, these elements located in the promoter were responsible for CYP6DA2 transcription, and CYP6DA2 expression was regulated by the transcription factors AhR and ARNT.

Abstract
Acetyl-coenzyme A carboxylase (ACC) catalyses the carboxylation of acetyl-coenzyme A (acetyl-CoA) to produce malonyl-CoA during the de novo synthesis of fatty acids. Spirotetramat, an inhibitor of ACC, is widely used to control a range of sucking insects, including the Aphis gossypii. In the present study, Reverse transcription quantitative real-time PCR (RT-qPCR) results demonstrated that ACC was significantly overexpressed in a laboratory-selected spirotetramat-resistant strain compared with the susceptible strain. ACC RNA interference significantly suppressed fecundity and led to cuticle formation deficiencies in resistant adults and nymphs compared with the control. The full-length ACC gene was sequenced from both resistant and susceptible cotton aphids, and a strong association was found between spirotetramat resistance and 14 amino acid substitutions in the biotin carboxylase domain and carboxyl transferase domain of the ACC gene. Furthermore, ACC activity was higher in resistant aphids than in the susceptible strain, and ACC in the resistant aphids exhibited significant insensitivity to spirotetramat and spirotetramat-enol. The results indicate that the overexpressed insensitive (mutated) ACC target played an important role in the high levels of spirotetramat resistance observed here. This association of amino acid substitution with resistance is the first report of a potential target site mechanism affecting spirotetramat in the cotton aphid.

Abstract
Objective:To investigate the seasonal disturbations and the rates of detection of EpsteinBarr virus (EBV), Human Bocavirus(HBoV), and polyomaviruses KI and WU (KIPyV and WUPyV) in adenoid and tonsil tissues during the absence of acute infection symptoms.Method:DNA expressions of EBV, HBoV, polyomaviruses KIPyV and WUPyV were investigated in children with chronic tonsillar and adenoidal diseases using real time polymerase chain reaction. The patients were divided into three group: adenoid group, chronic tonsillit group and hypertrophic tonsillitis group. The relationships of the expressions of these viruses with age, gender, recurrent infection and airway obstruction were analyzed. Seasonal variations in rates of detection of these viruses in adenoid and tonsil tissues were also investigated.Result:Considering adenoid specimens, HBoV was found to be the most frequent virus with the rate of 43.1%. In specimens of chronic tonsillitis and hypertrophic tonsils, EBV was the most frequently encountered virus (53.8%, and 32.0%, respectively). In children with hypertrophic adenoids, while HBoV was detected to be positive throughout the year, EBV was present throughout the year in children with recurrent tonsillitis.Conclusion:The detection of HBoV and EBV throughout the year in samples of children with asymptomatic chronic adenotonsillar diseases may indicate that these viruses may remain persistently in lymphoepithelial tissues of upper respiratory tract. Virus persistence may have a pathogenetic potential for development of lymphoid hypertrophy and a chronic stimulatory effect for inflammation.

Abstract
Objective: To investigate the effects of perioperative transfusion of blood components on the long-term prognosis of hepatocellular carcinoma (HCC) patients. Methods: A total of 339 patients with primary HCC who underwent curative hepatectomy between January 2003 and December 2010 at the Cancer Hospital, Chinese Academy of Medical Sciences were enrolled. The clinical data of the patients were retrospectively analyzed. These patients were divided into non-transfusion, fresh frozen plasma (FFP) transfusion only and concentrated red cells (CRC) transfusion groups. Disease-free survival and overall survival were estimated using the Kaplan-Meier method, and Cox regression was performed to identify clinicopathological factors related with survival. Results: Among the 339 patients, the 1-, 3- and 5-year disease-free survival rates were 63.1%, 35.4% and 22.4%, respectively, and the median disease-free survival was 22 months. While the 1-, 3- and 5-year overall survival rates were 90.5%, 69.5% and 56.4%, respectively, and the median overall survival was 72 months. The median disease-free survivals of the non-transfusion (n=181), FFP transfusion only (n=48) and CRC transfusion (n=110) groups were 28, 22 and 12 months, respectively, while the median overall survivals of the three groups were 99, 63 and 40 months respectively. Significant differences in the disease-free and overall survivals were observed among the three groups (both P<0.01). Multivariate Cox regression analyses showed that FFP transfusion only (HR=1.658, P=0.026), CRC transfusion (HR=1.470, P=0.030), serum alpha-fetoprotein>400 μg/L (HR=1.686, P=0.002), albumin<35 g/L (HR=1.782, P=0.047), tumor capsule (HR=0.597, P=0.012), tumor necrosis (HR=1.820, P=0.001) and the TNM stage Ⅲ or above (HR=2.537, P=0.000) were independent predictors of overall survival after hepatectomy. Conclusion: Both perioperative FFP only transfusion and CRC transfusion may have detrimental effect on the long-term prognosis of HCC.

Abstract
Cotton plants accumulate phytotoxins, such as gossypol and related sesquiterpene aldehydes, to resist insect herbivores. The survival of insects exposed to toxic secondary metabolites depends on the detoxification metabolism mediated by limited groups of cytochrome P450. Gossypol has an antibiotic effect on Aphis gossypii, and as the concentrations of gossypol were increased in the present study, the mortality of cotton aphids increased from 4 to 28%. The fecundity of the cotton aphids exposed to gossypol was also significantly reduced compared with the control. The transcriptional levels of CYP6DA2 in cotton aphids were significantly induced when exposed to gossypol, and knockdown of the CYP6DA2 transcripts by RNA interference (RNAi) significantly increased the toxicity of gossypol to cotton aphids. To further understand the gossypol regulatory cascade, the 5'-flanking promoter sequences of CYP6DA2 were isolated with a genome walker, and the promoter was very active and was inducible by gossypol. Co-transfection of the cap 'n' collar isoform C (CncC) and CYP6DA2 promoters dramatically increased the expression of CYP6DA2, and suppression of the CncC transcripts by RNAi significantly decreased the expression levels of CYP6DA2, and significantly increased the toxicity of gossypol to cotton aphids. Thus, the transcriptional regulation of CYP6DA2 involved the transcriptional factor CncC.

Abstract
PTEN, a tumor suppressor gene, suppresses cell survival, growth, apoptosis, cell migration and DNA damage repair by inhibiting the PI3K/AKT signaling pathway. In this study, the full-length Litopenaeus vannamei PTEN (LvPTEN) cDNA was obtained, containing a 5'UTR of 59bp, an ORF of 1269bp and a 3'UTR of 146bp besides the poly (A) tail. The PTEN gene encoded a protein of 422 amino acids with an estimated molecular mass of 48.3 KDa and a predicted isoelectric point (pI) of 7.6. Subcellular localization analysis revealed that LvPTEN was distributed in both cytoplasm and nucleus, and the tissue distribution patterns showed that LvPTEN was ubiquitously expressed in all the examined tissues. Vibrio alginolyticus challenge induced upregulation of LvPTEN expression. Moreover, RNAi knock-down of LvPTEN in vivo significantly increased the expression of LvAKT mRNA, while reducing that of the downstream apoptosis genes LvP53 and LvCaspase3. LvPTEN knock-down also caused a sharp increase in cumulative mortality, bacterial numbers, and DNA damage in the hemolymph of L. vannamei following V. alginolyticus challenge, together with a sharp decrease in the total hemocyte count (THC). These results suggested that LvPTEN may participate in apoptosis via the PI3K/AKT signaling pathway in L. vannamei, and play an important role in shrimp innate immunity.

Abstract
BACKGROUND AND AIMS Diabetes mellitus is associated with inflammatory endothelial activation and increased vascular leukocyte adhesion molecule expression, both playing a prominent role in the development of vascular complications. Centella asiatica (CA) and Lipoic Acid (LA) have shown anti-inflammatory and anti-oxidant properties in a variety of experimental models; however, their action on human umbilical vein endothelial cells (HUVECs), chronically exposed to hyperglycemia and pro-inflammatory environment during pregnancy, is still unknown. METHODS AND RESULTS In HUVECs from umbilical cords of gestational diabetic (GD) or healthy (C) women, both CA and LA affected tumor necrosis factor-α (TNF-α)-induced inflammation, being associated with a significant decrease in vascular cell adhesion molecule-1 (VCAM-1) and intercellular adhesion molecule-1 (ICAM-1) expression (western blot) and exposure (flow cytometry), as well as monocyte-HUVECs interaction (adhesion assay). Notably, this was associated with a significant reduction of an index of nitro-oxidative stress, such as the intracellular peroxynitrite levels (fluorescence detection by cytometric analysis), Mitogen-Activated Protein kinase (p44/42 MAPK) expression/phosphorylation levels and Nuclear Factor kappa-light-chain-enhancer of activated B cells (NF-κB p65) cytoplasm-nucleus translocation (flow cytometry). Overall our results indicate that both CA and LA used separately, and even better when combined, are effective to reduce the inflammatory response in TNF-α-treated HUVECs. Notably, this was more significant in GD than in C-HUVECs and also evident at baseline. CONCLUSION In conclusion, our in vitro study demonstrates that both CA and LA, or a combination thereof, are able to mitigate the potentially dangerous effects on the endothelium of chronic exposure to hyperglycemia in vivo.

Abstract
We observe D(0)-D(0) mixing in the decay D(0) → K+π- using a data sample of integrated luminosity 976 fb(-1) collected with the Belle detector at the KEKB e+e- asymmetric-energy collider. We measure the mixing parameters x'(2) = (0.09 ± 0.22) × 10(-3) and y'=(4.6 ± 3.4) × 10(-3) and the ratio of doubly Cabibbo-suppressed to Cabibbo-favored decay rates R(D) = (3.53 ± 0.13) × 10(-3), where the uncertainties are statistical and systematic combined. Our measurement excludes the no-mixing hypothesis at the 5.1 standard deviation level.

Abstract
Biomass yield is one of the most important traits for wheat (Triticum aestivum L.)-breeding programs. Increasing the yield of the aerial parts of wheat varieties will be an integral component of future wheat improvement; however, little is known regarding the genetic control of aerial part yield. A doubled haploid population, comprising 168 lines derived from a cross between two winter wheat cultivars, 'Huapei 3' (HP3) and 'Yumai 57' (YM57), was investigated. Quantitative trait loci (QTL) for total biomass yield, grain yield, and straw yield were determined for additive effects and additive x additive epistatic interactions using the QTLNetwork 2.0 software based on the mixed-linear model. Thirteen QTL were determined to have significant additive effects for the three yield traits, of which six also exhibited epistatic effects. Eleven significant additive x additive interactions were detected, of which seven occurred between QTL showing epistatic effects only, two occurred between QTL showing epistatic effects and additive effects, and two occurred between QTL with additive effects. These QTL explained 1.20 to 10.87% of the total phenotypic variation. The QTL with an allele originating from YM57 on chromosome 4B and another QTL contributed by HP3 alleles on chromosome 4D were simultaneously detected on the same or adjacent chromosome intervals for the three traits in two environments. Most of the repeatedly detected QTL across environments were not significant (P > 0.05). These results have implications for selection strategies in wheat biomass yield and for increasing the yield of the aerial part of wheat.

Abstract
Flavor, as one of the most important properties determining the acceptability and preference of fermented milks, is influenced by compositional and processing factors. In this study, we focused on the volatile organic compounds related to flavor during milk fermentation by Lactobacillus pentosus according to electronic nose analysis. Xylose (1% addition) metabolized by Lb. pentosus strongly affects the flavor of yogurt, with the potent volatile organic compounds of ethanol (3.08%), 2,3-butanedione (7.77%), and acetic acid (22.70%) detected using solid-phase microextraction coupled with gas chromatography-mass spectrometry analysis. Sensoryanalysis also showed skimmed yogurt fermented by Lb. pentosus with 1% xylose had the unique scores of sourness (acetic acid) and butter flavor (2,3-butanedione). Furthermore, α-acetolactate synthase and α-acetolactate decarboxylase in carbohydrate metabolism play important roles in milk fermentation. Under preferable conditions (pH 5.5, 42 °C) for α-acetolactate synthase and α-acetolactate decarboxylase, the relative content of potent flavor compound 2,3-butanedione was 10.13%, which was 2.55% higher than common culture condition (pH 4.5, 37 °C), revealing that xylose metabolized by Lb. pentosus has potential values for the milk product industry, such as the acceptability and preference of fermented milk product.
