Abstract
BACKGROUND AND PURPOSE Intravenous thrombolysis plus mechanical thrombectomy (IVT + MT) is the best current management of acute stroke due to large-vessel occlusion and results in optimal reperfusion for most patients. Nevertheless, some of these patients do not subsequently achieve functional independence. The aim was to identify baseline factors associated with 3-month independence after optimal reperfusion and to validate a prediction model. METHODS All consecutive patients with intracranial anterior large-vessel occlusion, with indication for IVT + MT and achieving optimal reperfusion (defined as modified Treatment in Cerebral Ischaemia score 2b-3), from the THRACE trial and the ETIS registry, were included in order to identify a prediction model. The primary outcome was 3-month independence [modified Rankin Scale (mRS) score ≤ 2]. Multivariate inferences invoked forward logistic regression, multiple imputation and bootstrap resampling. Predictive performance was assessed by c-statistic. Model validation was conducted on patients from the ASTER trial. RESULTS Amongst 139 patients (mean age 65.5 years; 54.3% female), predictors of 3-month mRS ≤ 2 (n = 82) were younger age [odds ratio 0.62 per 10-year increase; 95% confidence interval (CI) 0.53-0.72] and higher Alberta Stroke Program Early Computed Tomography Score (ASPECTS) (odds ratio 1.65 per 1-point increase; 95% CI 1.47-1.86) with c-statistic 0.77. Model validation (n = 104/181 patients with 3-month mRS ≤ 2) demonstrated a moderate discrimination (c-statistic 0.74; 95% CI 0.66-0.81) combining age and ASPECTS. The validation model was improved by the adjunction of three candidate variables that were found to be predictors. Addition of baseline National Institutes of Health Stroke Scale (NIHSS) score, history of vascular risk factor and onset-to-reperfusion time significantly improved discrimination (c-statistic 0.85; 95% CI 0.83-0.87). CONCLUSIONS After optimal reperfusion, younger age, higher ASPECTS, lower NIHSS score, shorter onset-to-reperfusion time and absence of vascular risk factor were predictive of independence and could help to guide patient management.

Abstract
Meat-quality traits play an essential role in meat poultry production. To determine the genetic mechanisms of meat quality in Pekin ducks, we performed a large-scale GWAS to identify quantitative trait loci affecting meat quality in Pekin ducks. We measured 10 traits in 542 Pekin ducks and genotyped each duck using genotyping-by-sequencing. The genetic parameters (genomic heritability, genetic correlation) for 10 meat-quality related traits were evaluated. Based on the large genotype-phenotype dataset, we performed GWASs for all of these traits. A total of 33 significant QTL (P < 3.03 × 10-5 ) across 13 chromosomes were identified by loci-based analysis. Some newly identified candidate genes were discovered for fat-deposition and meat-quality traits, including PAG1 for body weight and eviscerated weight, INTU and NUP35 for abdominal fat weight and ratio, NUP3 and ARHGDIB for skin fat weight and ratio, GOLGA5 for breast muscle toughness and breast tenderness, and CTDSPL and PKP1 for breast muscle thickness. The current study is the first systematic report regarding duck meat quality.

Abstract
Abstract
Background: Cancer patients are regarded as highly vulnerable group in the current SARS-CoV-2/COVID-19 pandemic. Up to date, the clinical characteristics of cancer patients with COVID-19 are largely unknown.
Patients and methods: In this retrospective cohort study, we collected and analyzed data of the cancer patients with y confirmed COVID-19 infection from three designated hospitals in Wuhan, China from Jan 13, 2020, to Feb 26, 2020. Univariate and multivariate analyses were performed to assess the risk factors associated with severe events defined as a condition that admission to an intensive care unit, the use of mechanical ventilation, or death. We also followed 124 cancer patients with immune checkpoint inhibitors (ICI) and their families for their infection rate and clinical outcome.
Results: Twenty-eight COVID-19 infected cancer patients were included with median age of 65.0 years (IQR:56.0-70.0) and male gender of 60.7% (17/28). Amount of these 28 patients, 7 (25%) had lung cancer, and 8 (28.6%) were considered to be infected via hospital-associated transmission. Fifteen (53.6%) patients had severe events with the mortality rate of 28.6%. The last anti-tumor treatment within 14 days from the diagnoses of COVID significant increased risk of developing severe events (HR=4.079, 95%CI 1.086-15.322, P=0.037). The common chest CT findings were ground-glass opacity (21, 75.0%) and patchy consolidation (13, 46.3%). The patchy consolidation on CT had a higher risk for developing severe events (HR=5.438, 95%CI 1.498-19.748, P=0.010). There was only one patient (1/124, 0.8%) who have been on ICI treatment for his metastatic HCC confirmed with COVID infection, and with mild clinic presentation and a short hospital course.
Conclusions: Cancer patients showed aggressive presentation and poor outcomes with the COVID-19 infection. It is recommended that vigorous screening for COVID-19 infection should be performed for cancer patients with anti-tumor. From our limited data, there is no evidence to suggest difference in cancer patients on ICI treatment.

Abstract
AIMS To develop an oral delivery system of glucagon-like peptide 1 (GLP-1) (28-36) for treating type-2 diabetes, B.S-GLP-1(28-36), a recombinant Bacillus subtilis spores transformed with a plasmid vector encoding five consecutive GLP-1 (28-36) nonapeptides with an enterokinase site was constructed. METHODS AND RESULTS GLP-1(28-36) nonapeptide was successfully expressed on the surface of B. subtilis spores and validated by Western blot and immunofluorescence. The therapeutic effect of oral administration of B.S-GLP-1(28-36) spores was evaluated in type 2 diabetic model mice. The efficacy of recombinant spores was examined for a period of 13 weeks after oral administration in diabetic mice. At the end of the sixth week, diabetic mice with oral administration of BS-GLP-1(28-36) spores showed decreased blood glucose levels from 2·4 × 10- 2 mol l-1 to 1·7 × 10- 2 mol l-1 . By the ninth week, the mean fasting blood glucose level in the experimental group was significantly lower than that in the control group 30 min after injection of pyruvate. At the end of the 10th week of oral administration, the blood glucose of the experimental group was significantly lower than that of the control group after intraperitoneal injection of glucose. By the 12th week, fasting blood glucose level and fasting insulin level were measured in all mice, the results showed that the recombinant spores increased the insulin sensitivity of mice. CONCLUSIONS The results of pathological observation showed that the recombinant spores also had a certain protective effect on the liver and islets of mice, and the content of GLP-1(28-36) in the pancreas of the experimental group was increased. SIGNIFICANCE AND IMPACT OF THE STUDY The results of this study revealed that GLP-1(28-36) nonapeptides can reduce blood glucose and play an important role in the treatment of type 2 diabetes.

Abstract
OBJECTIVE To investigate the effect of isoflurane on myocardial ischemia-reperfusion injury through the p38 mitogen-activated protein kinase (MAPK) signaling pathway. MATERIALS AND METHODS A total of 36 specific-pathogen-free (SPF) Sprague-Dawley rats were randomly divided into sham group (n=12), model group (n=12) and isoflurane group (n=12). In model group and isoflurane group, the myocardial ischemia-reperfusion injury model was established via the ligation of left anterior descending coronary artery (ischemia for 30 min and reperfusion for 3 h). In sham group, the left anterior descending coronary artery was not ligated, but the chest was opened and threaded using the same method. After ischemia, the rats in isoflurane group were inhaled with isoflurane. The cardiac function of rats in each group was detected before ischemia (T0) and once every 2 h after reperfusion (T1-T4) for a total of 5 times, and the cardiac function indexes included ejection fraction (EF), fractional shortening (FS), left ventricular systolic pressure (LVSP) and left ventricular end-diastolic pressure (LVEDP). After the rats were executed, the myocardial infarction tissues were taken for hematoxylin-eosin (HE) staining and 2,3,5-triphenyltetrazolium chloride (TTC) staining to observe the morphological changes in tissues and the degrees of myocardial ischemia and infarction. The malondialdehyde (MDA) content and superoxide dismutase (SOD) activity in myocardial cells in the infarction site in each group were detected using the MDA and SOD kits. Moreover, the expression levels of related proteins in the p38 MAPK signaling pathway in myocardial cells in the infarction site were detected via Western blotting. RESULTS In model group, the cardiac function was significantly damaged (p<0.01), there was significant pathological damage in the myocardium, the area of myocardial infarction was significantly increased (p<0.01), the MDA content was significantly increased (p<0.01), the SOD activity declined obviously (p<0.01), and the expression levels of p-p38 and p-tau protein were significantly increased (p<0.01) compared with those in control group. After intervention with isoflurane, the cardiac function of rats was significantly improved (p<0.01), the pathological damage in myocardial tissues was alleviated, the area of myocardial infarction was reduced (p<0.01), the MDA content declined (p<0.01), the SOD activity was increased (p<0.01), and the expression levels of p-p38 and p-tau protein were decreased (p<0.01). CONCLUSIONS Isoflurane can, through inhibiting the p38 MAPK signaling pathway, effectively protect the cardiac function of rats from myocardial ischemia-reperfusion injury, reduce the area of myocardial infarction, alleviate the pathological damage in myocardial cells and reduce the oxidative stress response.

Abstract
Aeromonas and Pseudomonas are important bacterial species involved in spoilage of refrigerated freshwater fish. In this study, 10 Aeromonas and seven Pseudomonas bacterial strains were isolated from spoiled grass carp and identified. Twelve of seventeen bacterial strains showed high potential of biofilm formation and 14 of 17 can produce extracellular protease. In order to explore the spoilage capacity of dual-species, the sterile grass carp fillets were inoculated with mono- and dual-species of Aeromonas salmonicida and Pseudomonas azotoformans strains. The results revealed significantly higher levels of the total viable count and total volatile basic nitrogen in dual-species as compared to mono-species from day 6. The higher contents of histamine, cadaverine and serious degradation in muscles tissue were also observed in dual-species after 10 days of storage. Results of in vitro experiments showed that the co-culture of A. salmonicida and P. azotoformans significantly increased the bacterial maximum growth rate, promoted the biofilm formation and improved the spoilage capacity of bacterial strains. This study has revealed that the co-culture of Aeromonas and Pseudomonas bacterial strains accelerated spoilage process of grass carp and increased biofilm formation. It indicates that the mixed-cultures of spoilage micro-organisms pose a huge threat to food industry.

Abstract
Background:Connective tissue disease-associated interstitial lung disease (CTD-ILD) is a class of refractory diseases.Non-specific treatment with hormone and immunosuppressive agents is mostly used at present, but the effect is limited and the long-term survival rate is not improved [1],while anti-fibrosis treatments (such as Pirfenidone and Nintedanib) have only recently been approved, the long-term efficacy is still unknown.Tofacitinib(TOFA), a JAK inhibitor, has recently been used to treat patients with severe dermatomyositis related interstitial pulmonary disease, with significantly improved survival rate [2-4].A basic study showed that TOFA improved interstitial pulmonary disease in mice by promoting the proliferation of myelogenic inhibitory cells [5].However, whether TOFA can affect the migration and invasion of human lung fibroblasts and further research to reveal the mechanism of its inhibition of pulmonary fibrosis has not been reported.Objectives:To investigate the anti - fibrosis effect of TOFA in CTD-ILD.Methods:Cell migration and invasion AssaysHLFs were incubated with TOFA for 72h, followed by TGF- β1 for 24h.DMEM serum-free medium was used to determine the cell density to 5. 0 × 107/L, 600 uL medium containing 10% fetal bovine serum was added to the lower compartment of Transwell chamber, and 200 uL cell suspension was added to the upper compartment.Incubate in incubator for 12 h.After fixation, staining and sealing, the cells were observed and counted under a microscope. At least 5 random field transmembrane cells were counted in each hole, and the mean value was taken.For the invasion assays, Transwell chamber coated with matrigel was used, and the cell incubation time was 16 h.Results:1. Effect of TOFA on HLFs migration function (Figure 1)Figure 1.Effect of TOFA on HLFs migration function(×200).Mean ± SEM. n = 5.The number of cells passing through the biofilm in the three groups was counted.It can be seen that TGF-β1 group significantly increased compared with control group (*P < 0.0001), and TOFA group significantly decreased compared with TGF- β1 group (#P < 0.0001), suggesting that TOFA can significantly inhibit TGF-β1- induced HLFs migration.2. Effect of TOFA on HLFs invasion function (Figure 2)Figure 2.Effect of TOFA on HLFs invasion function(×200).Mean ± SEM. n = 5.The number of cells passing through the matrigel in the three groups was counted.It can be seen that TGF-β1 group was significantly higher than the control group (*P < 0.0001), and TOFA group was significantly lower than TGF-β1 group(#P < 0.001), suggesting that TOFA can significantly inhibit the invasion function of HLFs induced by TGF-β1.Conclusion:TOFA can effectively inhibit the function of HLFs migration and invasion. Although further studies are needed to elucidate the mechanism by which TOFA inhibit the function of HLFs migration and invasion, our study suggests that TOFA has a potential therapeutic effect for CTD-ILD.References:[1]Aparicio, I.J. and J.S.

Abstract
Background Cancer patients are regarded as a highly vulnerable group in the current Coronavirus Disease 2019 (COVID-19) pandemic. To date, the clinical characteristics of COVID-19-infected cancer patients remain largely unknown. Patients and methods In this retrospective cohort study, we included cancer patients with laboratory-confirmed COVID-19 from three designated hospitals in Wuhan, China. Clinical data were collected from medical records from 13 January 2020 to 26 February 2020. Univariate and multivariate analyses were carried out to assess the risk factors associated with severe events defined as a condition requiring admission to an intensive care unit, the use of mechanical ventilation, or death. Results A total of 28 COVID-19-infected cancer patients were included; 17 (60.7%) patients were male. Median (interquartile range) age was 65.0 (56.0–70.0) years. Lung cancer was the most frequent cancer type (n = 7; 25.0%). Eight (28.6%) patients were suspected to have hospital-associated transmission. The following clinical features were shown in our cohort: fever (n = 23, 82.1%), dry cough (n = 22, 81%), and dyspnoea (n = 14, 50.0%), along with lymphopaenia (n = 23, 82.1%), high level of high-sensitivity C-reactive protein (n = 23, 82.1%), anaemia (n = 21, 75.0%), and hypoproteinaemia (n = 25, 89.3%). The common chest computed tomography (CT) findings were ground-glass opacity (n = 21, 75.0%) and patchy consolidation (n = 13, 46.3%). A total of 15 (53.6%) patients had severe events and the mortality rate was 28.6%. If the last antitumour treatment was within 14 days, it significantly increased the risk of developing severe events [hazard ratio (HR) = 4.079, 95% confidence interval (CI) 1.086–15.322, P = 0.037]. Furthermore, patchy consolidation on CT on admission was associated with a higher risk of developing severe events (HR = 5.438, 95% CI 1.498–19.748, P = 0.010). Conclusions Cancer patients show deteriorating conditions and poor outcomes from the COVID-19 infection. It is recommended that cancer patients receiving antitumour treatments should have vigorous screening for COVID-19 infection and should avoid treatments causing immunosuppression or have their dosages decreased in case of COVID-19 coinfection.

Abstract
Despite considerable advances in diagnosis and treatment of the critical illness-related corticosteroid insufficiency (CIRCI), it is still not clear that whether it is common in severe burn patients or not, and how clinical diagnosis, treatment, and research progress. Severe burn is a systemic disease involving the damage of multiple organs of the whole body. The course of the disease is relatively long, and there often exists persistent inflammation, immunosuppression, and catabolism. On the basis of CIRCI study, the epidemiological evidence, possible mechanism, suspicious clinical manifestations, diagnosis and treatment of severe burn-related corticosteroid insufficiency (SBRCI) were briefly reviewed in this article in order to help clinical diagnosis and treatment of SBRCI.

Abstract
PURPOSE We report an extremely rare, double ophthalmic artery configuration. METHODS We present 2D- and 3D-angiographic features of an anomalous origin of the ophthalmic artery. RESULTS The double ophthalmic artery was the result of the persistence of the primitive dorsal ophthalmic artery combined with the presence of a second orbital artery originating from the supracavernous internal carotid artery, passing through the superior orbital fissure and into the orbit to furnish the muscular, lacrimal and ethmoidal arteries and the medial long posterior ciliary artery. CONCLUSIONS A heretofore undocumented instance of ophthalmic artery duplication is presented. Knowledge of such variations is important for the planning of endovascular treatments and the comprehension of unusual angiographic images. Such fine arterial variants may very well be frequent, but difficult to demonstrate on simple 2D angiographies. Multiplanar reconstructions of 3D angiography data make it possible to diagnose rare, but embryologically predictable arterial variants.

Abstract
Vacuolar protein sorting 4 (Vps4) not only functions with its positive regulator vacuolar protein sorting 20-associated 1 (Vta1) in the multivesicular body (MVB) pathway but also participates alone in MVB-unrelated cellular processes. However, its physiological roles at the organism level remain rarely explored. We previously identified their respective homologues Bombyx mori Vps4 (BmVps4) and BmVta1 from the silkworm, a model organism for insect research. In this study, we performed fluorescence quantitative real-time PCR and Western blot to globally characterize the transcription and protein expression profiles of BmVps4 and BmVta1 during silkworm development and in different silkworm tissues and organs. The results showed that they were significantly up-regulated in metamorphosis, adulthood and embryogenesis relative to larval stages, and displayed a roughly similar tissue-and-organ specificity for transcriptions in silkworm larvae. Importantly, BmVps4 was down-regulated during the early period of the fifth instar, reaching the lowest level of transcription on Day 6, then up-regulated from Day 7 to the wandering, spinning and pupal stages, and down-regulated again in adulthood. Moreover, knocking down BmVps4 by RNA interference significantly inhibited silk gland growth, shortened spinning time, prolonged pupation, reduced pupal size and weight, and increased moth wing defects. Together, our data demonstrate the critical and broad requirements for BmVps4 in silkworm metamorphosis.

Abstract
Abstract Objective Logistic regression method was used to establish a multiple regression sex discriminant function to discriminate the complete skull model and the incomplete skull model without frontal bone, occipital bone and mandible of Uygur adults in Turpan, Xinjiang. Methods A total of 117 (60 male and 57 female) three-dimensional skull models were collected by CT. Sixteen cranial measurement indexes were measured and calculated by computer software. The multivariate regression sex discriminant function was established with Logistic regression method and retrospectively tested. Results Among the 16 measurement indexes, except for nose width (x7) and maximum frontal breadth (x13), the remaining 14 indexes had statistical significance of differences between male and female (P<0.05). For the discriminant function of complete skull established by eyebrow arch convexity (x4), mastoid width (x6), maximum cranial length (x12), cranial base length (x15), cranial circumference (x16), the male and female discrimination accuracy was 90.0% and 94.7%, respectively. For the sex discriminant function of incomplete skull without frontal bone established by mandibular angle width (x10), mandibular height (x11) and cranial circumference (x16), the discrimination accuracy of male and female was 85.0% and 84.2%, respectively. For the sex discriminant function of incomplete skull without occipital bone established by the index of eyebrow arch convexity (x4), the discrimination accuracy of male and female was 80.0% and 73.7%, respectively. For the sex discriminant function of incomplete skull without mandible established by frontal chord (x5) and occipital protrusion angle (x9), the discrimination accuracy of male and female was 85.0% and 78.9%, respectively. Conclusion The computer software and system developed in our study can achieve sex discrimination of complete skulls and incomplete skulls without frontal bone, occipital bone or mandible.

Abstract
BACKGROUND AND PURPOSE The multiple sclerosis prodrome remains poorly understood. We aimed to examine the prodrome in people with relapsing remitting multiple sclerosis at onset (RMS) and primary progressive multiple sclerosis (PPMS). METHODS We conducted a matched cohort study using clinical and linked health administrative data in two Canadian provinces. We identified people with RMS, PPMS and age- sex- and geographically-matched population controls, and compared the number of physician encounters (total number, per International Classification of Diseases chapter, and per physician speciality) in the five years before symptom onset. Negative binomial regression models were sex, age, socioeconomic status and calendar year adjusted. RESULTS We identified 1887 RMS, 171 PPMS cases, and 9837 matched population controls. No difference existed in the total number of encounters in the five years before index between RMS and PPMS, or between the phenotypes and their respective controls. Compared to RMS cases, PPMS cases had more nervous system-related encounters (adjusted rate ratio, 3.00; 95% confidence interval, 1.06-8.49) and fewer encounters with dermatologists (adjusted rate ratio 0.53; 95% confidence interval, 0.30-0.96). CONCLUSION Findings suggest that people with RMS and PPMS may both experience a prodrome, although aspects may differ.

Abstract
Chronic hepatitis C virus (HCV) infection is one of the most common causes of liver cirrhosis and hepatocellular carcinoma in China. The older standard treatment regimen for chronic hepatitis C was the pegylated interferon-alfa plus ribavirin(PR). Now newer oral medications called direct antiviral agents (DAAs) has been gradually changed to PR-based DAAs and interferon-free, oral DAAs; making chronic hepatitis C a curable disease. This article intends to expound the advantages and disadvantages of PR-based therapy and provide reference for the treatment of chronic hepatitis C.

Abstract
Analgesia and sedation play important roles in the overall treatment of critically burned adult patients. According to clinical actual situation of critically burned adult patients, a set of analgesic and sedative practices, including analgesia-based sedation, scientifically reasonable sedation status monitoring, early goal-directed sedation strategy, standardized and individualized strategy for analgesia and sedation, and early comfort using analgesia, minimal sedative, maximal human care strategy are recommended and widely implemented nowadays. However, guideline or consensus about how to provide analgesia and sedation treatment for critically burned adult patients is lacking. In this article, we discuss strategy for analgesic and sedative management in critically burned adult patients, with preexisting ideas in critical care medicine, pathophysiological characteristics of critically burned patients, and our clinical practice for reference.

Abstract
The allergy symptoms could arise from variable organ systems and have fluctuating nature in severity as well as symptoms. Moreover, these symptoms could be related to multiple pathological states like common cold, chronic obstipation, diarrhea, etc. On the other hand, food allergy diagnosis that usually spread by IgE-mediated inhalant also poses a great challenge in front of the scientific fraternity. So far, many advances in the field of allergy diagnosis, as well as therapeutics, have been made. These advances include skin prick testing (SPT), serum specific IgE (sIgE) level test, component resolved diagnosis (CRD) test, etc. The present review article would be focused on important pathological states associated with allergy observed commonly in children. Moreover, the latest developments about timely management and accurate diagnosis are also discussed.

Abstract
Objective: To semi-quantify the postoperative complications occurred after laparoscopic pancreaticoduodenectomy(LPD) using Clavien-Dindo score, thereafter exploring its impact factors. Methods: In this retrospective cohort study, the clinical data of 124 patients who had undergone LPD for periampullary tumor from June 2016 to June 2017 at Department of Biliary Pancreatic Surgery, Affiliated Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology were collected.Malignancy was confirmed based on postoperative pathological reports.Postoperative complications were semi-quantitated using Clavien-Dindo score.Multivariable logistic regression model was applied to explore the factors related to severe complications(Clavien-Dindo Ⅲb-Ⅴ). Results: Of the 124 patients, there were 64 males(51.6%) and 60 females(48.4%), with age of 57 years(range, 23-82 years). In total, postoperative complications occurred in 30 patients(24.2%). Among the 30 patients, 4 patients suffered Clavien-Dindo grade Ⅰ, 18 patients(14.5%) suffered Clavien-Dindo grade Ⅱ, 6 patients(4.8%) suffered Clavien-Dindo grade Ⅲa, 1 patient(0.1%) suffered Clavien-Dindo grade Ⅳb, and 1 patient(0.1%) suffered Clavien-Dindo grade Ⅴ.Intraabdominal hemorrhage occurred in 8 patients, pancreatic fistula was found in 10 patients(7 patients had biochemical leakage and 3 of them had grade B pancreatic fistula), both biliary fistula and gastrointestinal fistula were found in 1 patient.Abdominal infection occurred in 10 patients, both liver failure and renal failure occurred in one patient.Moreover, arrhythmia was found in two patients, and mortality occurred in one patient.Five patients suffered multiple complications.Univariable analysis showed that postoperative complications were associated with body mass index, American Society of Anesthesiologists(ASA) score, intraoperative blood transfusion, and pancreatic texture(P<0.05). In multivariable logistic regression, ASA grade Ⅲ, intraoperative blood transfusion, and pancreatic softness were independently related to postoperative complications after LPD(P<0.05). Conclusions: Clavien-Dindo score is feasible to be applied in management of patients with LPD.ASA score, texture of pancreas, and intraoperative blood transfusion were independently associated with postoperative complications.

Abstract
Objective: To explore the mediating effect of hemoglobin (Hb) and hematocrit (HCT) on the association between alcohol consumption and blood pressure, and provide evidence for the prevention and control of alcohol-attributed hypertension. Methods: 1 091 male (age >50 years old) participants with drinking habit were selected from the Guangzhou biobank cohort study (GBCS). Mediation analysis was used to evaluate the mediating effect of Hb and HCT on the association of alcohol consumption (unit/day) with systolic blood pressure (SBP), diastolic blood pressure(DBP), pulse pressure(PP) and mean arterial pressure (MAP). Results: After adjusting for age, body mass index, education level, personal annual income, smoking, occupation and physical activity, the associations of alcohol consumption with SBP, DBP, PP and MAP were partly mediated by Hb, the proportion of mediating effect was 11.8% (95%CI 4.8%-24.7%), 15.3% (95%CI 6.5%-32.0%), 8.4% (95%CI 2.2%-22.5%) and 13.5% (95%CI 5.9%-27.5%), respectively. The associations of alcohol consumption with SBP, DBP, and MAP were also partly mediated by HCT, the proportion of mediating effect was 6.3% (95%CI 1.0%-16.0%), 8.7% (95%CI 1.4%-21.4%), and 7.5% (95%CI 1.0%-18.6%), respectively. Conclusion: There is a significant mediating effect of Hb and HCT on the association between alcohol consumption and blood pressure. Besides efforts on alcohol control, the potential effects of alcohol-induced increase on Hb and HCT, which might also increase the blood pressure, need to be considered to achieve optimal monitoring and prevention of alcohol-related hypertension.

Abstract
BACKGROUND An erythroid cell-specific regulatory element (+5·8-kb) in the first intron of ABO is responsible for the antigen differential expression and the regulatory activity of the element was affected by the nucleotide mutation in the +5·8-kb region. Currently, many individuals with ABO subgroups were found in the Chinese population, but there was little information about the function of +5·8-kb region in these individuals. Here, we studied the mechanism of the mutation in the +5·8-kb region responsible for reducing of antigen expression in 30 ABO subtype Chinese individuals without mutation in the coding region or splicing site. MATERIALS AND METHODS The nucleotide sequence of the partial intron 1 covering the +5·8-kb site was amplified and directly sequenced. The haplotype with the novel mutation was obtained by the TOPO TA cloning. Both of the ABO promoter and the +5·8 kb regulatory element were subcloned into the basic luciferase reporter plasmid using the double endonuclease digestion. The promoter activity was examined by the dual-luciferase report vector with K562 cells. RESULTS A novel nucleotide substitution +5904 C>T located at RUNX1-binding site in the +5·8 kb site was identified from three individuals with B subtypes. +5890 T>G were found in three Bel and one Ael phenotypes. Cotransfection and luciferase assays demonstrated that the +5904 C>T could obviously reduce activity of the +5·8 kb site. CONCLUSION The study suggested that the transcriptional activity of the +5·8 kb site could be downregulated by the single point mutation of RUNX1 motif, leading to reduction in A or B antigen expression.

Abstract
The profiles of an acoustic field and electric potential of the forward and backward shear-horizontal (SH) acoustic waves of a higher order propagating in X-Y potassium niobate plate have been theoretically investigated. It has been shown that by changing electrical boundary conditions on a surface of piezoelectric plates, it is possible to change the distributions of an acoustic field and electric potential of the forward and backward acoustic waves. The dependencies of the distribution of a mechanical displacement and electrical potential over the plate thickness for electrically open and electrically shorted plates have been plotted. The influence of a layer with arbitrary conductivity placed on a one or on the both plate surfaces on the profiles under study, phase and group velocities of the forward and backward acoustic waves in X-Y potassium niobate has been also investigated. The obtained results can be useful for development of the method for control of a particle or electrical charge movement inside the piezoelectric plates, as well a sensor for definition of the thin film conductivity.

Abstract
Mite growth inhibitors (MGIs), such as etoxazole and hexythiazox, are valuable IPM tools for Tetranychus urticae control in hops due to their unique mode of action and selectivity. Hence, it is necessary to standardize bioassay methods to evaluate the efficacy of MGIs, monitor resistance, and identify mechanisms underlying MGI resistance in the field. Here, we developed a three-tiered approach for evaluating ovicidal toxicity of MGIs to T. urticae, which simulated different MGI exposure scenarios in the field. The most effective bioassay method was direct exposure of T. urticae eggs to MGIs. With this method, four field-collected T. urticae populations showed low-to-moderate resistance to MGIs. Cross-resistance among MGIs and from MGIs to bifenazate and bifenthrin was detected. Besides target site insensitivity, enhanced cytochrome P450 and esterase activities also contribute to the MGI resistance in hop yard-collected T. urticae populations. Low-to-moderate MGI resistance in T. urticae populations may be mediated by multiple mechanisms. Positive selection pressure on the I1017F mutation is moderate in field-collected T. urticae populations. Further studies are required to identify metabolic detoxification genes that confer resistance to MGIs for precise resistance monitoring.

Abstract
Background Current concepts of dry weight (DW) prescription are largely based on clinical symptoms because of the difficulty in assessing extracellular fluid volume (ECV) during dialysis. Intradialytic changes in ECV can be recorded as changes in extracellular resistance [Re] by continuous regional calf multifrequency bioimpedance spectroscopy (BIS). We hypothesized that relative changes in calf Re (Re at time ‘0’ over Re at time ‘t’ [Re-0/Re-t]) will become very small when ECV is reduced towards normal and individual dry weight is reached. Method Intradialytic continuous calf BIS was recorded repeatedly in 15 hemodialysis (HD) patients. The first measurement was performed at the prevailing clinical dry weight (CDW). Next measurements were made after post-HD body weight was gradually decreased by 0.2–0.3 kg per treatment. This procedure was iterated over several subsequent treatments until a treatment was observed where changes in Re-0/Re-t were < 1%. The weight at the end of this treatment was defined as “achieved dry weight (ADW)”. Each Re-0/Re-t curve was fitted using a Matlab program (curve fitting toolbox) to obtain the exact weight at 20 min after beginning of the flattening of the Re-0/Re-t slope (‘dry’ weight estimated from BIS, DW-BIS). Results Both mean ADW (80.5 ± 34.1 kg) and mean DW-BIS (80.6 ± 34.1) were significantly lower than CDW (81.4 ± 32.0 kg, p < 0.001), but there was no difference between ADW and DW-BIS. However, the average weight reduction from CDW to ADW (0.80 ± 0.15 kg) was significantly higher than from CDW to DW-BIS (0.66 ± 0.14 kg, p < 0.001, paired t-test). When ADW was achieved, pre-dialysis systolic blood pressure (SBP) was lower than at CDW (139.3 ± 32.5 mmHg, vs. 129.4 ± 33 mmHg, p < 0.05), post-HD SBP did not differ. The incidence of clinical symptoms of underhydration was similar at CDW (15 %) and DW-BIS (15 %), but higher at ADW (46 %). Conclusion Intradialytic continuous calf BIS allows the assessment of changes in extracellular calf resistance as an indicator of changes in extracellular fluid volume. Recording of a continuous Re-0/Re-t slope during dialysis appears to be a promising new tool for the prediction of dry weight in hemodialysis patients.

Abstract
Objective: To investigate the effects of non-muscle myosin ⅡA (NMⅡA) silenced bone marrow mesenchymal stem cells (BMSCs) on the lung damage of rats at early stage of smoke inhalation injury. Methods: Forty Sprague-Dawley rats were divided into control, simple injury, NMⅡA-BMSCs, and BMSCs groups according to the completely random method, with 10 rats in each group. Rats in control group inhaled air normally, while rats in the latter 3 groups inhaled smoke to reproduce model of smoke inhalation injury. At 30 min post injury, rats in simple injury group were injected with 1 mL normal saline via caudal vein, and rats in group BMSCs were injected with 1 mL the fifth passage of BMSCs (1×10(7)/mL), and rats in group NMⅡA-BMSCs were injected with 1 mL NMⅡA silenced BMSCs (1×10(7)/mL). At post injury hour (PIH) 24, abdominal aorta blood and right lung of rats in each group were harvested, and then arterial partial pressure of oxygen (PaO(2)), arterial partial pressure of carbon dioxide (PaCO(2)), and pH value were detected by blood gas analyzer. Ratio of wet to dry weight of lung was determined by dry-wet weight method. Pathological changes of lung were observed with HE staining. Bronchoalveolar lavage fluid (BALF) were collected, and then tumor necrotic factor-α (TNF-α) and interleukin-10 (IL-10) content of BALF was determined by enzyme-linked immunosorbent assay. Data were processed with one-way analysis of variance, Kruskal-Wallis H test, and least-significant difference test. Results: (1) At PIH 24, compared with those in control group, PaO(2) values of rats in simple injury, BMSCs, and NMⅡA-BMSCs groups were obviously decreased (with P values below 0.05), and PaCO(2) values were obviously increased (with P values below 0.05). Compared with those in simple injury group, PaO(2) values of rats in groups NMⅡA-BMSCs and BMSCs were obviously increased (with P values below 0.05), while PaCO(2) values were obviously decreased (with P values below 0.05). PaO(2) value of rats in group NMⅡA-BMSCs was obviously increased as compared with that in group BMSCs (P<0.05). The pH value of arterial blood of rats in simple injury group was obviously lower than that in control group (P<0.05). (2) At PIH 24, ratios of wet to dry weight of lung of rats in control, simple injury, BMSCs, and NMⅡA-BMSCs groups were 4.36±0.15, 7.79±0.42, 5.77±0.18, and 5.11±0.20, respectively. Compared with that in control group, ratio of wet to dry weight of lung of rats was obviously increased in the other 3 groups (with P values below 0.05). Compared with that in simple injury group, ratio of wet to dry weight of lung of rats was obviously decreased in groups BMSCs and NMⅡA-BMSCs (with P values below 0.05). Compared with that in group BMSCs, ratio of wet to dry weight of lung of rats in group NMⅡA-BMSCs was obviously decreased (P<0.05). (3) At PIH 24, alveolar structure of rats in control group was complete without abnormality. Compared with those in simple injury group, lung injury and infiltration of inflammatory cells of rats in groups BMSCs and NMⅡA-BMSCs were obviously alleviated, and alveolar structure was relatively complete with no thickening of alveolar wall. (4) At PIH 24, compared with that in control group, TNF-α content of BALF of rats in simple injury and BMSCs groups was obviously increased (with P values below 0.05). Compared with that in simple injury group, TNF-α content of BALF in groups BMSCs and NMⅡA-BMSCs was obviously decreased (with P values below 0.05). Compared with that in control group, IL-10 content of BALF in simple injury, NMⅡA-BMSCs and BMSCs groups were obviously increased (with P values below 0.05). Compared with that in simple injury group, IL-10 content of BALF in groups BMSCs and NMⅡA-BMSCs was obviously increased (with P values below 0.05). Compared with that in group BMSCs, IL-10 content of BALF in group NMⅡA-BMSCs was obviously increased (P<0.05). Conclusions: NMⅡA silenced BMSCs can alleviate lung damage of rats at early stage of smoke inhalation injury, showing better effectiveness than using BMSCs only.

Abstract
Objective: To examine the association between weight changes during early and middle adulthood and the risk of type 2 diabetes mellitus in middle aged and elderly population. Methods: Based on the Guangzhou Biobank Cohort Study (GBCS), 28 736 residents aged ≥50 years were included in Guangzhou. Multivariate logistic regression was used to analyze the association between body weight changes during early or middle adulthood and age when the heaviest weight reaching the threshold on the risk of type 2 diabetes mellitus in middle age or elderly population. Adjustments on age, smoking, alcohol consumption, physical activity, education level, occupation, district of residence and body mass index etc., were made. Results: The mean age was 64.3 (standard deviation=6.7) years in men and 61.0 (standard deviation=7.0) years in women, with the prevalence rates of diabetes as 13.1% and 13.7% in men and women, respectively. Compared to those with stable body weight, the risk of diabetes increased with weight gain during early and middle adulthood in both men and women (both P values for trend<0.01). Participants who gained more than 20 kg during early and middle adulthood were associated with the highest risk of diabetes in men (OR=2.83, 95%CI:1.99-4.02) and women (OR=3.13, 95%CI: 2.47-3.96). Compared to those who reached the highest weight at age 20, those who reaching the highest weight at 40 to 49 years were associated with the highest risk of diabetes, with OR being 5.32 (95%CI: 1.92-14.8) in men and 3.41 (95%CI: 2.49-4.67) in women, respectively. Weight loss in adulthood was associated with self-reported but not newly diagnosed diabetic cases in both middle and older aged men and women. Conclusion: Weight gain during early and middle adulthood may increase the risk of diabetes in middle and older aged population. The detrimental effect of obesity on diabetes might become significantly visible in the next decades.

Abstract
RATIONALE Studies have implied the positive association of JAK2/STAT3 signaling with the onset and severity of acute pancreatitis (AP). However, definitive functional study of JAK2/STAT3 signaling in the pathogenesis of acute pancreatitis in vivo is missing and its potential as a therapeutic target and the underlying mechanisms remain to be determined. OBJECTIVES The aim of this study was to explore the role of JAK2/STAT3 signaling in the pathogenesis of hyperlipidemia-intensified caerulin-induced AP and its potential as a therapeutic target. METHODS AND RESULTS Using the caerulin-induced acute pancreatitis rat model, we showed that JAK2/STAT3 signaling was activated in pancreas and systemic inflammation was increased during AP. Pharmacological suppression of JAK2 by its inhibitor AG490 robustly protected against tissue damage, attenuated JAK2/STAT3 signaling and inflammatory responses. Local pancreatic tissue damage and phosphor- JAK2 in the pancreatic tissue were enhanced in animals fed with high fat diet compared to chow-diet fed animals. Interestingly, JAK2 inhibitor AG490 significantly inhibited pancreas necrosis and systemic inflammation in animals fed with high fat or chow-diet, but did not affect STAT3 signaling. CONCLUSION These results establish that JAK2 activation plays a significant role in the pathogenesis of caerulin-induced AP in animals on both chow and high-fat diets by regulating necrosis and systemic inflammation. Thus, our results not only clarify novel signaling mechanisms in AP but also suggest that JAK2 might constitute a target in the management of hyperlipidemia-intensified caerulin-induced AP.

Abstract
IL-37, a newly found anti-inflammatory cytokine of the IL-1 family, has both extracellular and intracellular functions. Accumulating evidences indicate that it is also involved in tumor progression. However, the mechanism and its intracellular target are unclear. In this study, clinical data from 84 patients showed that loss or reduced expression of IL-37 in lung adenocarcinoma tissues was significantly associated with tumor metastasis. We further provided evidence that IL-37 inhibited effectively tumor metastasis in vitro and in vivo. Moreover, we uncovered a novel mechanism by which IL-37 suppressed tumor cell migration via its intracellular mature form (amino acids 46-218). Intracellular mature form of IL-37, but not its extracellular form, markedly inhibited migration of multiple kinds of tumor cells through inhibiting Rac1 activation. Mechanistically, intracellular mature IL-37 directly bound to the CAAX motif in the C-terminal hypervariable region of Rac1, and then inhibited Rac1 membrane translocation and subsequent downstream signaling. Our research identifies intracellular mature IL-37 as a novel endogenous inhibitor of Rac1. Given the crucial roles of Rac1 in tumor angiogenesis and metastasis, intracellular mature IL-37 might serve as a potential strategy for the control of Rac1 activity and tumor progression.

Abstract
Temperate insects have evolved diapause, a period of programmed developmental arrest during specific life stages, to survive unfavourable conditions. During the diapause preparation phase (DPP), diapause-destined individuals generally store large amounts of fat by regulating nutrition distribution for the energy requirement during diapause maintenance and postdiapause development. Although nutritional patterns during the DPP have been investigated at physiological and biochemical levels in many insects, it remains largely unknown how nutritional metabolism is regulated during the DPP at molecular levels. We used RNA sequencing to compare gene expression profiles of adult female cabbage beetles Colaphellus bowringi during the preoviposition phase (POP) and the DPP. Most differentially expressed genes were involved in specific metabolic pathways during the DPP. Genes related to lipid and carbohydrate metabolic pathways were clearly highly expressed during the DPP, whereas genes related to protein metabolic pathways were highly expressed during the POP. Hormone challenge and RNA interference experiments revealed that juvenile hormone via its nuclear receptor methoprene-tolerant mediated the expression of genes associated with nutritional metabolism during the DPP. This work not only sheds light on the mechanisms of diapause preparation, but also provides new insights into the molecular basis of environmental plasticity in insects.

Abstract
AIM Whether different adiposity measures predict incident diabetes differentially in general Chinese populations is unclear. We investigated this in Chinese people aged 50+ years in the Guangzhou Biobank Cohort Study. METHODS Waist circumference and BMI were measured at baseline, and fasting glucose was measured at both baseline and follow-up examinations. Incident diabetes was defined as fasting glucose ≥ 7.0 mmol/l, glucose after 2-h oral glucose tolerance test ≥ 11.1 mmol/l, and/or self-reported physician-diagnosed diabetes during the follow-up period. RESULTS Of 15 752 people without diabetes at baseline from 2003 to 2008, 1779 (11.3%) developed incident diabetes during the follow-up from 2008 to 2012 (mean = 3.6 years, sd = 1.0). After mutually adjusting each other and adjusting for other potential confounders, waist circumference showed a higher predictive value than BMI. The odds ratio (OR) (95% confidence interval (CI) was 1.50 (95% CI 1.37-1.64) for a 1 sd increment in waist circumference and 1.21 (95% CI 1.11-1.33), for a 1 sd increment in BMI. Similarly, after mutual adjustment, abdominal obesity was associated with an almost twofold odds of incident diabetes (OR 1.93, 95% CI 1.71-2.17), which was higher than that for general obesity (OR 1.76, 95% CI 1.50-2.06). The area under receiver operating characteristic curve (AUC) for waist circumference was higher than that for BMI [AUC = 0.676 (95% CI 0.660-0.686) vs. 0.665 (95% CI 0.651-0.678), P = 0.02]. CONCLUSION Abdominal obesity predicted incident diabetes in older people better than general obesity. Our findings may be an early warning signal for local government or public health practitioners to develop and investigate more effective intervention programmes for diabetes, and should also be disseminated to the public to pay more attention to this important public health issue.

Abstract
OBJECTIVE In this prospective cohort study, the efficacy and action mechanism of an intestinal probiotic formulation, Golden Bifid, in severe hand, foot, and mouth disease (HFMD) were determined in 63 consecutively admitted patients successfully treated in the Pediatrics Emergency Department of our hospital. PATIENTS AND METHODS All patients had a persistent fever; 43 patients had rashes on hands, feet, crissum, and hips; and 45 patients had neurological signs and symptoms. Patients were treated with standard supportive therapy along with ventilator-assisted respiration combined with bedside hemofiltration for removal of circulatory toxins and to achieve acid-base equilibrium and electrolyte stability. Golden Bifid was orally administered for 2 weeks, and vaccination was performed after patients were in stable condition. Additional supportive nursing care was also provided. Patients were categorized into the effective treatment (n = 40) and ineffective treatment (n = 23) groups. RESULTS Serum levels of proinflammatory factors [interleukin (IL)-1β, IL-6, tumor necrosis factor-α, and interferon-γ] were significantly decreased and those of anti-inflammatory factors (IL-13, IL-4, and IL-10) were significantly increased after treatment in the effective treatment group. In contrast, in the ineffective treatment group, serum proinflammatory factor levels were significantly increased and serum anti-inflammatory factor levels were significantly decreased. Between-group difference was significant. After treatment, serum D-lactic acid, diamine oxidase, and endotoxin levels were significantly decreased in the effective group and significantly increased in the ineffective group by intra- and inter-group comparisons. CONCLUSIONS Intestinal probiotics were effective in relieving clinical symptoms of severe HFMD, maintaining intestinal immunity and anti-inflammatory responses, and enhancing intestinal barrier function, with better safety and efficacy, which should be further evaluated for more extensive clinical applications.

Abstract
Objective: To investigate the clinical outcomes and the accuracy of O-arm-navigation system assisted pedicle screw insertion in dystrophic scoliosis secondary to neurofibromatosis type Ⅰ(NF-1). Methods: A retrospective study was conducted in 41 patients with dystrophic NF-1-associated thoracic scoliosis who were surgically treated at Department of Orthopaedics, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School between June 2012 and October 2014 with more than 18 months follow-up. The patients were then divided into two groups: 18 patients were under the assistance of O-arm-navigation-based pedicle screw insertion (O-arm group) and the remaining 23 patients' pedicle screws insertion were conducted by free-hand (free-hand group). The X-ray and CT were analyzed to investigate the correction rate and safety of pedicle insertion. t-test was used to analyze measurement data and χ(2) test was used to analyze accuracy of screw insertion between the two groups. Results: The mean coronal Cobb angle was 63.2°±8.7° in the O-arm group and 66.9°±7.4° in the free-hand group (P>0.05), which was then corrected into 23.1°±6.8° and 30.2°±7.6°(t=2.231, P=0.031) after surgery respectively.Operation time was (265.0±70.3)minutes and estimated blood loss was (1 024±465)ml in the O-arm group. Operation time and estimated blood loss was (243.0±49.6)minutes and (1 228±521)ml respectively in the free-hand group, which had no significant difference between the two groups. However, the implant density was higher in the O-arm group than that in the free-hand group ((64.1±10.8)% vs.(44.3±15.3)%)(t=4.652, P=0.000). The O-arm group comprised 122 screws, of which 72.9% were excellent, 22.1% were good and 4.9% were bad. The free-hand group comprised 136 screws and 48.5% of them were excellent, 33.8% were good and 17.6% were bad.Accuracy of pedicle screw insertion was higher in the O-arm group than that in the free-hand group(χ(2)=10.140, P<0.05). By June 2016, the average follow-up period was (20.9±3.4)months(ranging from18 to 26 months), including (20.3±3.1)months in the O-arm group and (21.4±5.5)months in the free-hand group. At last follow-up point, coronal correction loss was significantly higher in the free-hand group than that in the O-arm group (6.3°±2.6° vs. 4.4°±1.6°)(t=2.719, P=0.009). Conclusions: Compared with free-hand technique, O-arm-navigation technique could enhance accuracy of pedicle insertion and implant density of dystrophic region in dystrophic NF-1-associated scoliosis patients, which result in a better correction rate and less correction loss. Besides, the advantage of O-arm-navigation do not increase operative time and estimate blood loss.
