Abstract
Shanghai Municipal Center for Disease Control and Prevention has implemented an active comprehensive surveillance project of acute respiratory infections in adults in Shanghai, including influenza like illness (ILI) and severe acute respiratory infection (SARI). By testing and identifying a variety of respiratory pathogens, it was found that influenza viruses were the main pathogens in 172 ILI cases in 2019. The positive rates of influenza A (H1N1) pdm09 virus, influenza A (H3N2) virus and influenza B virus Victoria lineage were 30.81%, 14.53% and 30.55%, respectively. The positive detection of influenza A (H1N1) pdm09 virus peaked in the first quarter. The positive rate of enterovirus/human rhinovirus was 6.40%, with a positive detection peak in the third quarter, while the positive rate of adenovirus was 4.65% with a positive detection peak in the second quarter of the year. Two human coronavirus (HCoV)-OC43 positive samples, 1 HCoV-HKU1 positive sample and 1 HCoV-NL63 positive sample were detected, respectively, and no HCoV-229E positive sample was detected. The detection rate of Staphylococcus aureus was 17.44%, and the detection rate of Klebsiellapneumoniae was 9.88%. Influenza viruses were also the main pathogens in 1 447 SARI cases. The positive rates of influenza A (H1N1) pdm09 virus, influenza A (H3N2) virus and influenza B virus Victoria lineage were 5.46%, 1.73% and 0.30%, respectively. The positive detection of influenza A (H1N1) pdm09 virus (17.50%) peaked in the first quarter. The total positive detection rate of enterovirus/human rhinovirus was 2.97%, the positive detection peaked in the first quarter. The positive rate of Mycoplasma pneumoniae was 3.25% and the positive rate of Legionella was 1.04%. 5 HCoV-229E positive samples, 10 HCoV-OC43 positive samples, 7 HCoV-HKU1 positive samples and 6 HCoV-NL63 positive samples were detected. Eight strains of Staphylococcus aureus, 4 strains of Pseudomonas aeruginosa and 3 strains of Klebsiella pneumoniae were detected after cultures. By implementing the active surveillance, we not only detected a case of human infection with avian influenza A(H7N9) virus in time, but also preliminary understood the pathogenic spectrum characteristics and seasonality of ILI and SARI in Shanghai. In recent years, the surveillance methods have been continuously improved and the number of sentinel hospitals has increased gradually. In particular, for the response to COVID-19, the Surveillance Information Reporting System of Acute Respiratory Infection based on HIS system has been promoted to cover the whole city, which might lay a foundation for the active surveillance and early warning of emerging infectious diseases in the future.

Abstract
Dairy production is rapidly increasing in developing countries and making significant contributions to health, nutrition, environments, and livelihoods, with the potential for still greater contributions. However, dairy products can also contribute to human disease in many ways, with dairyborne disease likely being the most important. Health risks may be from biological, chemical, physical, or allergenic hazards present in milk and other dairy products. Lacking rigorous evidence on the full burden of foodborne and dairyborne disease in developing countries, we compiled information from different sources to improve our estimates. The most credible evidence on dairyborne disease comes from the World Health Organization initiative on the Global Burden of Foodborne Disease. This suggests that dairy products may has been responsible for 20 disability-adjusted life years per 100,000 people in 2010. This corresponds to around 4% of the global foodborne disease burden and 12% of the animal source food disease burden. Most of this burden falls on low- and middle-income countries (LMIC). However, the estimate is conservative. Weaker evidence from historical burden in high-income countries, outbreak reports from LMIC and high-income countries, and quantitative microbial risk assessment suggest that the real burden may be higher. The economic burden in terms of lost human capital is at least US$4 billion/yr in LMIC. Among the most important hazards are Mycobacterium bovis, Campylobacter spp., and non-typhoidal Salmonella enterica. The known burden of chemical hazards is lower but also more uncertain. Important chemical hazards are mycotoxins, dioxins, and heavy metals. Some interventions have been shown to have unintended and unwanted consequences, so formative research and rigorous evaluation should accompany interventions. For example, there are many documented cases in which women's control over livestock is diminished with increasing commercialization. Dairy co-operatives have had mixed success, often incurring governance and institutional challenges. More recently, there has been interest in working with the informal sector. New technologies offer new opportunities for sustainable dairy development.

Abstract
Objective: To investigate the association between grip strength, rapid gait speed and cognition in people aged 50 and above in Shanghai. Methods: Cross-sectional data was collected from the World Health Organization (WHO) study on global ageing and adult health (SAGE) wave 1 (2009-2010). A questionnaire survey was conducted among 8 643 participants aged 50 years old and above selected by using multistage random cluster sampling strategies in Shanghai. Factor analysis was applied to evaluate and generate cognitive function overall score.Association between grip strength, rapid gait speed and cognition was examined by a two-level hierarchical linear model. Results: A total of 8 175 participants were included in this study, who were (62.9±9.7) years old, including 3 782 (46.3%) males. The average grip strength and rapid gait speed of participants were (27.46±12.01) kg and (1.44±0.43) m/s respectively. The average scores of verbal recall (VR), verbal fluency (VF), forward digit span (FDS), backward digit span (BDS) and total cognitive scores were (5.72±0.09), (12.67±0.35), (6.84±0.10), (4.32±0.14) and (60.50±0.95) respectively. Grip strength was positively associated with VR, VF, FDS, BDS and overall cognition (standardized β=0.036, 0.079, 0.042, 0.046 and 0.043 respectively, P<0.05), and rapid gait speed was also positively associated with VR, VF and overall cognition (standardized β=0.040, 0.031, 0.039 respectively, P<0.05) after adjusted for age, sex, residence, education level, marital status, household income, co-morbidity of chronic conditions, BMI, drinking, smoking, fruits, vegetables intake and physical activities. Conclusion: Grip strength and rapid gait speed are both positively associated with cognitive function of people aged 50 and above, which would be indicators to evaluate their cognition.

Abstract
Abstract
Background and aims
Nearly half of all heart failure patients have heart failure with preserved ejection fraction (HFpEF). Due to differences in pathophysiology of heart failure with preserved and reduced ejection fraction, as well as a paucity of studies, the treatment of hHFpEF remains a challenge.
We aimed to determine the rate of hospital readmission within 30 days of acute or acute on chronic HFpEF and its impact on mortality and health care utilization in the United States. We also focused on patient demographics as well as independent variables affecting readmission.
Methods
We performed a retrospective study using the Agency for Health-care Research and Quality's Health-care Cost and Utilization Project (HCUP), Nationwide Readmission Database (NRD) for the year of 2017 (data on approximately 18 million hospital stays at 2,454 hospitals in the United States). We collected data on hospital readmissions of 60,514 adults who were hospitalized for acute or acute on chronic diastolic heart failure and discharged. The primary outcome was the rate of all-cause readmission within 30 days of discharge. Secondary outcomes were reasons for readmission, readmission mortality rate, and resource use (length of stay, total hospitalization costs and charges). Independent risk factors for readmission were identified using Cox regression analysis.
Results
The 30-day rate of readmission was 21%. Only 1,175 (9.17%) of readmissions were associated with an admitting diagnosis of acute on chronic diastolic heart failure. The most common readmission diagnosis was hypertensive chronic kidney disease with heart failure (1,245; 9.7%). Readmission cases were associated with increased in-hospital mortality compared to index admission (7.9% vs 2.9%, p=0.000). Readmission was associated with a total of 81,997 hospital days. Total health care in-hospital economic burden was $206 million (in costs) and $779 million (in charges). Significant predictors of increased thirty-day readmission were Medicaid insurance (1.15, 1.05–1.27, p=0.004), higher Charlson co-morbidity score (1.08, 1.06–1.09, p=0.000), patient admitted to teaching hospital (1.09, 1.04–1.15, p=0.001) and longer stays in the hospital (1.01, 1.01–1.02, p=0.000). Residence in a small metropolitan (0.91, 0.86–0.97, p=0.003) or micropolitan area (0.83, 0.77–0.90, p=0.000), older age (0.99, 0.993–0.997, p=0.000), female sex (0.91, 0.86–0.95, p=0.000), private (0.85, 0.77–0.93, p=0.000) or no insurance (0.70, 0.53–0.93, p=0.015) were associated with lower odds of readmission. Interestingly discharges to rehabilitation had no effect on re-admission (0.67, 0.28–1.6, p=0.381).
Conclusions
In conclusion patients hospitalized for acute or acute on chronic HFpEF, we found that 21% of patients were readmitted to the hospital within 30 days of discharge. Readmissions were associated with higher mortality and resource utilization. Most readmissions were due to cardiorenal syndrome.

Abstract
OBJECTIVE To investigate whether MNX1-AS1 can accelerate epithelial-mesenchymal transition (EMT) of osteosarcoma cells via activating MNX1. PATIENTS AND METHODS The expression pattern of MNX1-AS1 in osteosarcoma tissues and cell lines was examined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Moreover, the cytoplasmic and nuclear levels of MNX1-AS1 in osteosarcoma cells were also determined. The regulatory effects of MNX1-AS1 on viability, clonality, migratory, and invasive abilities of the osteosarcoma cells were evaluated. The relative levels of MNX1 and EMT-related genes influenced by MNX1-AS1 were detected. The methylation ability in the promoter of the osteosarcoma cells transfected with si-MNX1-AS1 or MNX1-AS1 vector was determined by the whole genome bisulfite sequencing. RESULTS MNX1-AS1 was upregulated in osteosarcoma tissues and cell lines, which was mainly expressed in the nucleus. The knockdown of MNX1-AS1 markedly attenuated viability, clonality, migratory, and the invasive abilities of the osteosarcoma cells. Besides, the transfection of si-MNX1-AS1 in U2OS and MG63 cells downregulated MNX1 and Snail, and upregulated E-cadherin. The methylation ability increased after the knockdown of MNX1-AS1, while the overexpression of MNX1-AS1 obtained the opposite trends. CONCLUSIONS MNX1-AS1 mediates EMT of the osteosarcoma cells via activating MNX1, thereafter accelerating the progression of the osteosarcoma.

Abstract
Objective: To investigate the efficacy of sodium zirconium cyclosilicate on emergency correction of hyperkalemia in chronic kidney disease patients. Methods: Patients with chronic kidney disease who were admitted to the Department of Nephrology of the First Affiliated Hospital of Zhengzhou University from May to June 2020 were selected. Those who had hyperkalemia and took sodium zirconium cyclosilicate powder were finally included. The patient's clinical data and laboratory results were collected. Results: A total of 24 results were included from 21 patients. The age of patients was (48.9±13.5) years old. Fourteen patients were male, and 7 patients were female. After 2 hours of administration, the venous potassium level decreased from (5.85±0.52) mmol/L to (5.15±0.43) mmol/L (P<0.001, n=21), with an average decline of (0.71±0.43) mmol/L. Meanwhile, the arterial potassium level decreased from (5.50±0.40) mmol/L to (4.88±0.33) mmol/L (P<0.001, n=10), with an average decline of (0.62±0.29) mmol/L. Based on the initial venous potassium level, the patients were further divided into three groups. The average potassium decrease in<5.5 mmol/L group (4 patients), 5.5-<6.0 mmol/L group (11 patients) and ≥6.0 mmol/L group (6 patients) was (0.46±0.26) mmol/L, (0.62±0.38) mmol/L and (1.04±0.45) mmol/L, respectively. There was statistically significant difference of potassium reduction among the three groups (P=0.045). Moreover, the extent of potassium reduction was positively correlated with baseline venous potassium level (r=0.603, P=0.004, n=21). The study did not reveal any treatment-related adverse event. Conclusion: Sodium zirconium cyclosilicate powder can rapidly and effectively reduce the serum potassium level in chronic kidney disease patients with hyperkalemia.

Abstract
OBJECTIVE To investigate the protective effect of Resveratrol (RES) on TNF-α-induced inhibition of osteogenic differentiation, thus alleviating the progression of osteoporosis (OP). MATERIALS AND METHODS OP model in rats was first conducted by performing ovariectomy (OVX). Rats were randomly divided into sham group, OVX group, and RES+OVX group. Body weight of each rat was regularly recorded every week. Bone mineral density (BMD) of rat femoral metaphysis was measured by micro-CT. Changes in radial degrees and loads of rat femora were examined through three-point bending experiments. Relative levels of OCN and Runx2 in each group were determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Alkaline phosphatase (ALP) activity and calcification ability were assessed through ALP staining and alizarin red staining, respectively. Bone mesenchymal stem cells (BMSCs) were extracted from healthy rats and divided into control group, Tumor necrosis factor-α (TNF-α) group, RES group, and TNF-α+RES group based on different treatments. Relative levels of OCN and Runx2, ALP activity, and calcification ability in each group were detected in the same way. Finally, protein levels of NF-κB and β-catenin in BMSCs were determined. RESULTS Rats in each group gained body weight during the experimental period, especially those in OVX group and RES+OVX group. No significant difference in the body weight was found between OVX group and RES+OVX group. BMD in rat femora of RES+OVX group was higher than in OVX group but lower than sham group. Elastic/max radial degree and elastic/max load of femora were markedly reduced in OVX group compared to RES+OVX group. Relative levels of OCN and Runx2, ALP activity and calcification ability decreased in OVX group relative to sham group, which were partially reversed by RES treatment. After osteogenic differentiation in BMSCs induced with TNF-α, viability and calcification ability were markedly reduced and were upregulated by RES treatment. Moreover, RES treatment enhanced the downregulated levels of OCN and Runx2 in BMSCs undergoing TNF-α induction. Upregulated protein levels of nuclear factor kappa-B (NF-κB) and β-catenin in TNF-α-induced BMSCs were downregulated by RES treatment. CONCLUSIONS The inhibited osteogenic differentiation of BMSCs undergoing TNF-α induction is improved by resveratrol treatment, which contributes to alleviate the progression of osteoporosis.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of dexmedetomidine (DEX) on kidney injury in sepsis rats through the Toll-like receptor 4 (TLR4)/myeloid differential protein-88 (MyD88)/nuclear factor-κB (NF-κB)/inducible nitric oxide synthase (iNOS) signaling pathway. MATERIALS AND METHODS A total of 30 Sprague-Dawley (SD) rats were randomly divided into three groups, including the control group (n=10), lipopolysaccharide (LPS)-induced acute kidney injury (AKI) group (model group, n=10) and DEX treatment group (DEX group, n=10). The model of sepsis was successfully established in rats. The levels of serum creatinine (Cr), blood urea nitrogen (BUN), serum interleukin-6 (IL-6), IL-1β, IL-10 and tumor necrosis factor-α (TNF-α) were detected via enzyme-linked immunosorbent assay (ELISA). The pathological changes in kidney tissues were detected via hematoxylin-eosin (HE) staining. Furthermore, the mRNA and protein expressions of TLR4, MyD88, NF-κB, and iNOS in the kidney were detected via fluorescence quantitative Polymerase Chain Reaction (PCR) and Western blotting, respectively. RESULTS Compared with the control group, rats in the model group showed significant kidney injury, markedly increased levels of serum Cr, BUN and pro-inflammatory cytokines, remarkably decreased the level of IL-10 (p<0.05), and significantly increased mRNA and protein expressions of TLR4, MyD88, NF-κB, and iNOS. In the DEX group, AKI was markedly improved, while the expressions of inflammatory cytokines were remarkably declined. Furthermore, the mRNA and protein expressions of TLR4, MyD88, NF-κB, and iNOS decreased significantly. CONCLUSIONS DEX has a protective effect on LPS-induced AKI, whose mechanism may be related to the inhibition of the TLR4/MyD88/NF-κB/iNOS pathway.

Abstract
OBJECTIVE The current study aimed to examine the role and mechanism of a conserved long noncoding RNA termed NORAD (noncoding RNA activated by DNA damage, also named LINC00657) in gastric cancer (GC) progression. PATIENTS AND METHODS Quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to determine the expression level of relevant genes in GC cell lines. Cell proliferation was examined by cell counting kit-8 (CCK-8) assays. Cell migration and invasion were detected by transwell migration and invasion assays. Protein levels of the indicated genes were detected by Western blotting. Cell apoptosis was examined by flow cytometry. RESULTS Results showed that NORAD knockdown decreased cell proliferation, migration and invasion but increased cell apoptosis. NORAD knockdown affected the expression of genes related to apoptosis and Epithelial-Mesenchymal Transition (EMT). In addition, NORAD's depletion resulted in reduced Ras Homolog Family Member A (RhoA) and Rho-associated coiled-coil containing protein kinase 1 (ROCK1) expression. Furthermore, NORAD's expression was positively correlated with RhoA and ROCK1 expressions in GC based on The Cancer Genome Atlas (TCGA) database. CONCLUSIONS Our results demonstrate the oncogenic role of NORAD in gastric cancer progression.

Abstract
AIMS Interventions using prebiotic inulin-type fructans (ITFs) are widely prescribed to modulate the gut microbiota composition and activity to promote health. However, the impacts of ITFs on post-antibiotic reconstitution of the gut microbiome remain incompletely understood. The aim of the present study was to investigate the effects of ITFs supplementation on intestinal inflammation, the composition of the intestinal microbiota and the colonic transcriptome after antibiotic treatment. METHODS AND RESULTS Male BALB/c mice were subjected to an antibiotic cocktail (ABx) treatment for 7 days, and their microbiomes were then reconstituted either spontaneously or with ITFs supplementation (5%) for 14 days. Our data showed that ITFs supplementation delayed the recovery of antibiotic-induced colitis compared with the spontaneous recovery. Neither ITFs supplementation nor spontaneous recovery could restore the microbial community composition at the genus level back to its initial composition. ITFs supplementation increased the relative abundance of some beneficial bacteria and butyrate levels, but resulted in selective blooms of some opportunistic pathogens and elevated the pathways associated with diseases linked to gut microbiota function. Both ITFs supplementation and spontaneous recovery could restore the colonic transcriptome nearly to the initial profile to a certain extent; however, ITFs supplementation delayed the restoration of the immunoglobulin genes compared to spontaneous recovery. CONCLUSION These data showed that post-antibiotic ITFs consumption did not always lead to beneficial effects but might lead to potential adverse effects in the context of dysbiosis. SIGNIFICANCE AND IMPACT OF THE STUDY These findings highlighted that caution is required when supplementing ITFs to restore intestinal homeostasis in the context of dysbiosis resulting from broad-spectrum antibiotics.

Abstract
As an underdeveloped country, the coronavirus disease 2019 (COVID-19) epidemic has posed a major risk to the health and economy of Pakistan. The SIR (susceptible-infected-recovered) model of epidemiologic analysis predicts that there should have been more cases since late March 2020 in Pakistan. We therefore sought to investigate COVID-19's prevalence and epidemiologic trends in Pakistan. Research for COVID-19 is still in its early stages, so data were collected from official websites and research journals, then analyzed for the disease's prevalence, epidemiology, mortality and recoveries. The results indicated that a rapid increase had indeed occurred in the number of COVID-19 infections in Pakistan, with the first case reported on 25 February, 2020. From 25 February 25 to April, 2020, COVID-19 infected 11,155 people in Pakistan, with 237 deaths (2.12%) and 2527 recoveries (19.96%). We found a statistically significant positive correlation between the prevalence of COVID-19 and the mortality ratio (r = 0.983, r 2 = 0.966; p ≤ 0.05). We concluded that proper management must be undertaken to improve the quarantine system, and the World Health Organization guidelines must be closely followed to cope with COVID-19. There is no vaccine for COVID-19, so antiviral drugs (interferon alfa, ribavirin) may be useful to prevent COVID-19; however, severe control measures implemented in China have significantly mitigated the spread of COVID-19. Suspected and confirmed cases must be treated in separate rooms. Staying home and social distancing are the safe way to proceed.

Abstract
BACKGROUND AND PURPOSE Thrombectomy up to 24 hours after stroke onset in patients with specific ischemic brain volumes remains a challenge, because many stroke centers do not apply specialized software to calculate ischemic volumes at advanced imaging. We aimed to establish the association between relative filling time delay on CTP source imaging and ischemic volume parameters and the infarct penumbra to core volume mismatch in patients with acute ischemic stroke. MATERIALS AND METHODS Consecutive patients with acute ischemic stroke and with M1 segment MCA with or without terminal ICA occlusions on baseline CTA and CTP within 24 hours of stroke symptom onset were included. Ischemic volumes were analyzed with software based on CTP maps. Relative filling time delay was classified into 4 grades-grade 0: relative filling time delay = 0 seconds; grade 1: relative filling time delay >0 to ≤4 seconds; grade 2: relative filling time delay >4 to ≤8 seconds; and grade 3: relative filling time delay > 8 seconds. Differences in ischemic volume parameters among relative filling time delay grades were tested. RESULTS We recruited 138 patients (median age, 69 years; 62.3% male). Different median volumes of the infarct core (grade 0, 7.3 mL; grade 1, 23.3 mL; grade 2, 45.7 mL; grade 3, 135 mL [P < .001]) and the penumbra (grade 0, 47.6 mL; grade 1, 90 mL; grade 2, 110 mL; grade 3, 92 mL [P = .043]) were observed among relative filling time delay grades. Target mismatch (defined by the criteria of the DEFUSE 3 trial) was identified in 71.7% of the patients (99/138). A relative filling time delay grade ≤ 1 independently predicted target mismatch, with a sensitivity of 0.79 (95% CI, 0.7-0.87) and a specificity of 0.66 (95% CI, 0.49-0.8). CONCLUSIONS Relative filling time delay grade based on CTP source imaging is a simple and effective parameter for evaluating ischemic volumes and target mismatch in patients with acute ischemic stroke. Further studies that compare relative filling time delay grade with clinical functional outcomes are necessary.

Abstract
Objective: To analyze the relationship between both quality and duration of sleep and type 2 diabetes in middle-aged and elderly people in Shanghai. Method: Baseline data was from the '2017 epidemiological survey in Shanghai community residents aged 35 and above on type 2 diabetes'. Restricted cubic splines were used to draw dose-response curves to show the relationship between PSQI score, sleep duration and type 2 diabetes. Logistic regression model was used to analyze the effects of quality and duration of sleep as well as the interaction, on type 2 diabetes. Results: Results showed that the average PSQI score was (4.09±0.10) points, the proportion of poor sleep quality was 12.55% (95%CI: 10.77-14.58) and the average sleep duration was (7.19±0.03) hours. The relationship between PSQI score and diabetes appeared linear, with the relationship between sleep duration and diabetes as U-shaped. After adjusting for confounders, both poor sleep quality (>7 for PSQI score) and short sleep duration (sleep duration <6 hours) significantly increased the risk of type 2 diabetes, with OR=1.17 (95%CI: 1.06-1.30) and 1.20 (95%CI: 1.01-1.41), respectively. From the interaction analysis, data showed that after adjusting for confounders, both sleep duration <6 hours (OR=1.30, 95%CI: 1.12-1.52) and ≥8 hours (OR=1.79, 95%CI: 1.04-3.07) with poor sleep quality would increase the risks on diabetes. Conclusion: Both poor sleep quality and short sleep duration were associated with the risk of diabetes, while long sleep duration was only associated with the risk of diabetes when accompanied by poor quality of sleep.

Abstract
Fusarium head blight (FHB) is a devastating disease to cereal crops worldwide that decreases grain yield, grain quality, and causes mycotoxin contamination. FHB resulted in an estimated $2 billion USD loss in the US between 1993 and 2001, and 520 million Canadian dollars (CAD) in Canada in the 1990s. In the wheat producing areas in Canada and the United States, it is perceived that significant progress has been made to manage FHB, but the economic impact of various innovations has not been quantified. Therefore, the main objective of this study was to assess the economic impact of various practices deployed in the province of Ontario, Canada, on managing deoxynivalenol and improving agronomic performance in winter wheat since an epidemic in 1996. The impacts of four hypothetical FHB management scenarios on total deoxynivalenol (DON) concentration and grain yield were estimated in field experiments that compared old (mid-1990s) and modern era (mid-2010s) production practices. Management scenarios included old and new cultivars varying in susceptibility to FHB, fungicide application and nitrogen rates. These impacts were applied to farm survey data collected in 1996 to estimate farm revenue and profit. A similar economic estimate was conducted for the recent FHB epidemic in 2013. If a modern MR cultivar, a modern fungicide, and the combination were deployed in the epidemic of 1996, farm revenue would have increased by 26-32, 23-36 and 48-60%, and profit increased by 88-157, 42-59 and 165-207 CAD per ha, respectively, depending on the nitrogen rate. In the province of Ontario, up to 68 million CAD of revenue losses could have been avoided in 1996 with the use of modern agronomic and FHB management practices. Our study has quantified some of the major economic advances in managing FHB and DON since 1996, but further research is needed to develop better cultivars and management strategies.

Abstract
Objective: To explore the genetic and environmental effects on alcohol intake. Methods: Data on 9 231 pairs of adult twins of the same sex was collected from the Chinese National Twin Registry (CNTR), between 2015 and 2018 and used in this study. Structural equation model was used to estimate the effects of genetic and environmental factors on alcohol intake. Results: A total of 9 231 pairs of twins were included in the analysis, of which 6 085 pairs were monozygotic (MZ). The average age of MZ was (36.91±13.07) years old, and males accounted for 56.80%. The average age of dizygotic twins (DZ) was (35.22±12.48) years old, and males accounted for 55.91%. There were 350 pairs of alcohol-drinking twins were with high-risk, accounting for 1.90% and another 367 pairs (1.99%) were with medium-risk. Alcohol-drinkers with medium-risk were affected by additive genetics, common and unique environmental factors, seen among the twins. The overall heritability appeared as 24.3% (95%CI: 0 to 56.8%). Furthermore, 50.7% of the variation (95%CI: 20.4%-79.0%) could be explained by the common environmental factors and 24.9% (95%CI: 18.3%-36.5%) by unique environmental factors. High-risk related drinking behavior was affected by both common and unique environmental factors. The common environmental component appeared as 75.6% (95%CI: 69.6%-80.8%) and unique environmental component as 24.4% (95%CI: 19.2%-30.4%), respectively. Gender difference was seen in the heritability of those with medium or high-risk drinking behaviors. The heritability of men was 30.8% (95%CI: 9.8%-53.5%), while in women it was mainly affected by the environment. Conclusion: Both alcohol drinkers with medium and high-risk drinking behaviors were mainly affected by the environment factors and gender. With the increase of drinking volume, the effect of environment on drinking behaviors became more obvious.

Abstract
Background:Weight, dietary patterns, vitamin D, physical activity and grip strength have been suggested to be associated with bone loss in older adults. However, studies have yet been performed to investigate the associations between these factors and radial bone microarchitecture.Objectives:This study aimed to describe the associations of weight, dietary patterns, serum 25-hydroxyvitamin D (25(OH)D) concentrations, physical activity and grip strength with bone measures in older adults.Methods:Cross-sectional data on 201 older adults (mean age 72 years, female 46%) from a population-based cohort study were analysed. Weight, dietary patterns, serum 25(OH)D concentrations, physical activity (steps per day), grip strength were collected and analysed from baseline to 10-year follow-up. Areal bone mineral density (aBMD) at spine, hip and whole body were measured by dual-energy X-ray absorptiometry (DXA). Radial cortical and trabecular bone microarchitectures were measured by high-resolution peripheral computed tomography (HRpQCT). Multivariable linear regression was used to analyse associations of study factors with bone measures.Results:Weight was positively associated with radial bone area (total: β=0.18, 95% CI: 0.07, 0.29; cortical: β=0.12, 95% CI: 0.03, 0.21; trabecular: β=0.18, 95% CI: 0.05, 0.32), and was inversely associated with compact cortical volumetric bone mineral density (vBMD) (β= -0.19, 95% CI: -0.37, -0.01) and trabecular thickness (β= -0.25, 95% CI: -0.43, -0.07). Ten-year changes in weight were not significantly associated with bone measures, apart from radial trabecular separation (β= 0.15, 95%CI: 0.009, 0.28). Western dietary pattern scores were inversely associated with radial vBMD (total: β= -0.17, 95% CI: -0.32, -0.01; cortical: β= -0.19, 95% CI: -0.34, -0.04; compact cortical: β= -0.19, 95% CI: -0.34, -0.04; outer transitional zone: β= -0.20, 95% CI: -0.35, -0.06), and were positively associated with cortical porosity (cortical: β= 0.18, 95% CI: 0.03, 0.33; compact cortical: β= 0.19, 95% CI: 0.04, 0.34; outer transitional zone: β= 0.20, 95% CI: 0.06, 0.35). Steps per day were not significantly associated with bone measures, apart from inner transitional zone area and thickness (β= 0.12, 95% CI: 0.003, 0.24; β= 0.19, 95% CI: 0.05, 0.33). Healthy food pattern scores, serum 25(OH)D and grip strength were not significantly associated with radial HRpQCT measures.Conclusion:Higher weight, but not weight change, was beneficial for radial cortical and trabecular bone area but also associated with worse compact cortical vBMD and trabecular thickness. Higher western dietary pattern scores had adverse effects on radial vBMD and cortical porosity while physical activity had inconsistent associations.Disclosure of Interests:None declared

Abstract
OBJECTIVES The 'hypervirulent' variant of Klebsiella pneumoniae (hvKp) is a predominant cause of community-acquired pyogenic liver abscess in Asia, and is an emerging pathogen in Western countries. hvKp infections have demonstrated 'metastatic' dissemination in immunocompetent hosts, an unusual mode of infection associated with severe complications. Two cases alerted us to the possible presence of hvKp at our hospital, both involving elderly Hispanic males who presented with recurrent fever, bacteraemia, epigastric pain and liver abscesses/phlegmon, thus prompting an assessment of hvKp prevalence. METHODS A surveillance of K. pneumoniae blood, body fluid and wound isolates was conducted using real-time PCR to detect virulence-associated genes (uni-rmpA, iucA and peg344). Positive isolates were further characterized by wzi gene sequencing to determine capsular types (K-type) and by multilocus sequence typing and pulsed-field gel electrophoresis to determine strain relatedness. RESULTS Four-hundred and sixty-three K. pneumoniae isolates, derived from 412 blood, 21 body fluids and 30 abdominal wound specimens, were screened over a 3-year period. Isolates included 98 multidrug-resistant strains. Eighteen isolates from 17 patients, including two from the index patient, screened positive for all three virulence genes. Sixteen of 18 positive isolates had K-types associated with hvKp, and isolates from different patients were unrelated strains, indicating likely community acquisition. Of 13 patients with significant morbidity, five died; eight patients had co-existing hepatobiliary disease, and six had diabetes mellitus. CONCLUSIONS Multiple strains of hvKp are emerging in New York City and are associated with high mortality relative to multidrug-resistant and classical Klebsiella infections. Co-existing hepatobiliary disease appears to be a potential risk factor for these infections.

Abstract
Objective: To analyze the heritability of coronary heart disease (CHD) among the Chinese twin adults. Methods: A total of 20 477 same-sex twin pairs aged 25 years and older from the Chinese National Twin Registry were interviewed. Structure equation model was used to estimate the heritability of CHD. Results: After adjusting for age and gender, the overall heritability of CHD was 0.75(0.68-0.81). Stratified analyses showed that genetic factors play a more important role in CHD incidence in ≥40 years or female twins. While the development of CHD was mainly influenced by environmental factors in 25-39 years or male twins. Conclusion: CHD is influenced by both genetic and environmental factors and the heritability is high.

Abstract
Objective: To analyze the effect of influenza vaccination intervention among key populations of chronic disease management in communities of Shanghai. Methods: A total of 50 787 patients aged ≥60 with diabetes, hypertension and chronic obstructive pulmonary disease (COPD) in Huangpu, Yangpu, Baoshan and Qingpu districts of Shanghai from January 2013 to August 2017 were selected as the intervention group, and 52 268 people from key populations with chronic disease management in Xuhui, Hongkou, Jiading and Fengxian districts were selected as the control group according to the geographical location and economic level. The intervention group accepted follow-up and health education of influenza vaccination via chronic disease outpatient based on information system. The implementation time of the intervention was from September 2017 to January 2018. The basic information and diagnosis information of two groups, and intervention completion of the intervention group were obtained from Shanghai chronic disease management information system and hospital record system. Results: The age of the intervention group and the control group were (76.76±8.33) and (77.97±8.51) years old, respectively (P<0.001); and there were statistical differences in gender, occupational and influenza vaccination rate between the two groups (P<0.001). A total of 28 644 (56.40%) subjects of the intervention group received intervention. There was no significant difference in age composition between finished and unfinished intervention groups (P=0.095), and there was significant difference in gender composition (P=0.044). Before the intervention, the vaccination rate of the intervention group was 0.75% (382 subjects) which was lower than that of the control group with 1.02% (533 subjects) (χ(2)=20.96, P<0.001). After the intervention, the vaccination rate of the intervention group was 1.73% (496 subjects) which was higher than that of the control group with 1.42% (744 subjects) (χ(2)=11.65, P=0.001). Subjects that were male, younger, uptake of influenza vaccine before the intervention, received intervention and professional and technical personnel were more likely to take influenza vaccine, with OR (95%CI) 1.29 (1.13-1.47), 0.97 (0.96-0.98), 260.30 (215.21-314.83), 1.85 (1.61-2.11) and 1.48 (1.10-1.99), respectively. Conclusion: Influenza vaccination intervetion raised the vaccination rate of key population of chronic disease management. Male, younger, those who had been vaccinated before the intervention, who received the intervention, and professional and technical personnel were more likely to be vaccinated.

Abstract
The emergence of the COVID-19 pandemic has severely affected medical treatment protocols throughout the world. While the pandemic does not affect hand surgeons at first glance, they have a role to play. The purpose of this study was to describe the different measures that have been put in place in response to the COVID-19 pandemic by hand surgeons throughout the world. The survey comprised 47 surgeons working in 34 countries who responded to an online questionnaire. We found that the protocols varied in terms of visitors, health professionals in the operating room, patient waiting areas, wards and emergency rooms. Based on these preliminary findings, an international consensus on hand surgery practices for the current viral pandemic, and future ones, needs to be built rapidly.

OBJECTIVE To describe the association of subchondral and systemic bone mineral density (BMD) with knee and hip replacements (KR and HR, respectively) due to osteoarthritis. DESIGN 1,095 participants (mean age 63 years, 51% female) were included. At baseline, subchondral BMD of the medial and lateral tibia in three regions of interest (ROI) for the right knee, and systemic BMD of the lumbar spine, femoral neck, total hip and whole-body, were measured using dual-energy X-ray absorptiometry. Subchondral BMD of the hip was not measured. Competing risk regression models were used to estimate sub-distribution hazard ratios (SHRs) of KR/HR per one standard deviation (SD) higher in BMD measures, with adjustment of potential confounders. RESULTS Over 12.2 years, 79 (7.2%) participants underwent a KR and 56 (5.1%) an HR due to osteoarthritis. For the right side, medial subchondral BMD in ROI-3 was associated with an increased risk of KR (SHR 1.95 per SD; 95% Confidence Interval [CI], 1.57 to 2.43). In contrast, systemic BMD was not associated with the risk of KR, but higher BMD at the lumbar spine (1.42, 1.07 to 1.88) and whole-body (1.29, 1.00 to 1.66) were associated with an increased risk of HR at both sides. CONCLUSIONS Subchondral BMD is positively associated with an increased risk of KR and systemic BMD with an increased risk of HR, suggesting a role of BMD in the progression of osteoarthritis.

Abstract
Objective: To quantitate the association between birth weight and phenotypes of physical indicators in adulthood, i.e. BMI and waist circumference (WC) and to what degree genetic or environmental factors affect birth weight-obesity association. Methods: A total of 6 623 gender matched twin pairs aged 25 to 79 years were recruited through the Chinese National Twin Registry. The twins reported their own birth weight, current height and weight, and WC using a self-administered questionnaire. BMI was calculated according to the self-reports of body height and weight. Within twin-pair design was used to quantitate the association between birth weight and phenotypes related to obesity while bivariate structural equation models were used to decompose the phenotype correlation. Results: After adjusted for multiple factors, twin-pair analyses within monozygotic (MZ) showed that, on average, a 1.0 kg increase in birth weight corresponded to an increase of 0.33 kg/m(2) in BMI and 0.95 cm in WC in adulthood (P<0.001). Bivariate structural equation models showed significant positive unique environmental correlation between birth weight and the two obesity-related phenotypes. Conclusion: The study supported the role of twin-specific supply line factors on relationship between birth weight and physical indicators in adulthood.

Abstract
Schistosomiasis was once heavily endemic in Jiangsu Province. Following the control efforts for several decades, schistosomiasis was almost eradicated in all endemic counties in Jiangsu Province in 1980, and transmission control was achieved in the province in 2011. According to the principle of "implementing the control measures with adaptation to local circumstances and guiding the control programs with classified interventions", an integrated strategy with emphasis on the management of both infectious sources and snails has been recently employed for schitsosomiasis control in Jiangsu Province. In addition, a sensitive and highly effective surveillance system has been built and the application of novel techniques and information construction has been intensified to effectively interrupt the transmission of schistosomiasis in the Province. Transmission interruption of schistosomiasis was achieved in all endemic counties in Jiangsu Province. The paper summarizes the endemic situation of schistosomiasis, progress of schistosomiasis control, and major schistosomiasis control measures implemented during the stage of transmission interruption in Jiangsu Province.

Abstract
Objective: To investigate the clinicopathological features, special morphologic variants and potential diagnostic traps of classical follicular dendritic cell sarcoma (FDCS). Methods: A total of 25 cases of classical FDCS diagnosed in the First Hospital Affiliated to Army Medical University from 2006 to 2018 were examined by hematoxylin-eosin staining, immunohistochemistry and in situ hybridization for Epstein-Barr virus-encoded mRNA (EBER). Meanwhile, the types and characteristics of the special variants of FDCS were summarized along with those reported in the literature. Results: The age of patients ranged from 23 to 77 years (mean 52 years), the male to female ratio was 1.5, and the maximum diameter of tumor was 1.5 to 20 cm (mean 7.4 cm). Twelve cases (48%) were misdiagnosed at the initial evaluation. Follow-up information was available for 17 patients, and the follow-up time was 5 to 96 months. The propotion of patients having recurrence, metastasis and mortality was 3/17, 5/17 and 2/17, respectively. Microscopically, besides the typical morphology, 10 cases of FDCS showed special histomorphologies and/or structures, including those mimicking lymphoepithelioma-like carcinoma, desmoplastic infiltrating carcinoma, classical Hodgkin's lymphoma (CHL), anaplastic large cell lymphoma (ALCL) and hemangiopericytoma. These morphologic variants were potential diagnostic pitfalls and warranted attention. Immunohistochemistry showed that more than two markers of follicular dendritic cells (such as CD21, CD23, CD35, etc.) were expressed in cases showing typical morphology and the special variants. All 25 cases were all negative for EBER by in situ hybridization. Conclusions: Classical FDCS is rare, besides the typical morphologic features, there are many special variants. In particular, these may be confused with lymphoepithelioma-like carcinoma in the nasopharynx, CHL or ALCL in the mediastinum/lymph node. Awareness of these variants is essential for accurate diagnosis.

Abstract
Objective: To investigate the molecular characterization of adult diarrhea cases caused by enterotoxic Escherichia coli (ETEC) and explore the practical model of epidemiology for laboratory technique and data needs based on the surveillance network. Methods: Epidemiological design and sampling targeted adult cases ETEC caused diarrhea in epidemic season. The enterotoxin type, serogroup, resistance, colonization factor and molecular type of ETEC were identified. Multiple dynamic phenotypic characteristics of ETEC were indicated by multidimensional and multivariable data. Results: From 2016 to 2018, 84 eligible ETEC strains were detected. The dominant serums/toxins were O∶6 (STh), O∶25 (LT), O∶159 (STh), O∶153 (STh). O∶6 (STh+CS21), which replaced O∶25 and O∶159 as the popular clones in 2018. Six cases of O∶153 (STh+CFA/I+CS8+PT34) in outbreak in 2017 were imported ones. The resistance rates of ETEC strains detected in adults to sulfasoxazole, naproxinic acid, ampicillin and azithromycin were more than 30%, multidrug resistance (MDR) reached 58.3%. Serum/toxin types suggested that attenuated strains were more likely to become MDR. Molecular typing confirmed that the genetic similarity of the dominant clone of O∶6 serogroup (PT20-24) was higher than O∶25 and O∶159. There was a high correlation between the minimal inhibitory concentration (MIC) of azithromycin and the resistant gene mphA (87.5%, 28/32). O∶6 (STh+CS21+mphA) resistant clone was first detected in 2016. Conclusion: A new epidemic clone in adult ETEC diarrhea cases in Shanghai was O∶6 (STh+CS21+mphA). For the first time the association between azithromycin resistance gene mphA and a serum group of ETEC was observed. Multidimensional and multivariate analysis techniques based on epidemiology can help reveal the potential transmission pattern of ETEC for the accurate surveillance and early warning of outbreaks.

Abstract
Objectives To investigate the prevalence, clinical characteristics, and prognosis of thrombocytopenia (TP) in Chinese patients with systemic lupus erythematosus (SLE). Methods The study was conducted based on the Chinese SLE Treatment and Research group (CSTAR) registry. Thrombocytopenia was defined as the platelet count<100,000/mm3 at enrollment. Severe thrombocytopenia was defined as the platelet count<50,000/mm3. The prevalence of SLE-related TP, the associations of thrombocytopenia with demographic data, organ involvements, laboratory findings, disease activity, damage, and mortality were investigated. Results Of 2104 patients with SLE, 342 patients (16.3%) were diagnosed with thrombocytopenia. The prevalence of neuropsychiatric SLE, vasculitis, myositis, nephritis, mucocutaneous lesions, pleuritis, fever, leukocytopenia and hypocomplementemia were significantly higher in patients with thrombocytopenia (p<0.05). SLE disease activity index (SLEDAI) was significantly higher in patients with thrombocytopenia (p<0.05). Multivariate analysis showed that leukocytopenia (OR = 2.644), lupus nephritis (OR = 1.539), hypocomplementemia (OR = 1.497) and elevated SLEDAI (OR = 1.318) were independently associated with thrombocytopenia (p<0.05). Long disease duration (OR = 1.006) was an independent risk factor of severe thrombocytopenia, while anti-rRNP (OR = 0.208) was an independent protective factor of severe thrombocytopenia (p<0.05). Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia (RR = 1.006). The 6-year survival of patients with thrombocytopenia was significantly lower than patients without thrombocytopenia (88.2% vs. 95.5%). Conclusions Thrombocytopenia was a common manifestation of SLE and was associated with leukocytopenia, nephritis and severe disease activity. Severe thrombocytopenia tended to occur in long-term and relatively inactive SLE. Patients with SLE-related thrombocytopenia has a decreased long-term survival rate. Long disease duration was an independent risk factor of mortality in patients with thrombocytopenia.

Abstract
Dietary phosphorus concentration greatly affects pig's growth performance, environmental impact and diet cost. A total of 1080 pigs (initially 5.9 ± 1.08 kg) from three commercial research rooms were used to determine the effects of increasing standardized total tract digestible (STTD) P concentrations in diets without and with phytase on growth performance and percentage bone ash. Pens (10 pigs/pen, 9 pens/treatment) were balanced for equal weights and randomly allotted to 12 treatments. Treatments were arranged in two dose titrations (without or with 2000 units of phytase) with six levels of STTD P each. The STTD P levels were expressed as a percentage of NRC (2012) requirement estimates (% of NRC; 0.45 and 0.40% for phases 1 and 2, respectively) and were: 80%, 90%, 100%, 110%, 125% and 140% of NRC in diets without phytase and 100%, 110%, 125%, 140%, 155% and 170% of NRC in diets with phytase. Diets were provided in three phases, with experimental diets fed during phases 1 (days 0 to 11) and 2 (days 11 to 25), followed by a common diet from days 25 to 46. On day 25, radius samples from one median-weight gilt per pen were collected for analysis of bone ash. During the treatment period, increasing STTD P from 80% to 140% of NRC in diets without phytase improved average daily gain (ADG; quadratic, P < 0.01), average daily feed intake (ADFI; quadratic, P < 0.05) and gain-feed ratio (G : F; linear, P < 0.01). Estimated STTD P requirement in diets without phytase was 117% and 91% of NRC for maximum ADG according to quadratic polynomial (QP) and broken-line linear (BLL) models, respectively, and was 102%, 119% and >140% of NRC for maximum G : F using BLL, broken-line quadratic and linear models, respectively. When diets contained phytase, increasing STTD P from 100% to 170% of NRC improved ADG (quadratic, P < 0.05) and G : F (linear, P < 0.01). Estimated STTD P requirement in diets containing phytase was 138% for maximum ADG (QP), and 147% (QP) and 116% (BLL) of NRC for maximum G : F. Increasing STTD P increased (linear, P < 0.01) the percentage bone ash regardless of phytase addition. When comparing diets containing the same STTD P levels, phytase increased (P < 0.01) ADG, ADFI and G : F. In summary, estimated STTD P requirements varied depending on the response criteria and statistical models and ranged from 91% to >140% of NRC (0.41% to >0.63% of phase 1 diet and 0.36% to >0.56% of phase 2 diet) in diets without phytase, and from 116% to >170% of NRC (0.52% to >0.77% of phase 1 diet and 0.46% to >0.68% of phase 2 diet) for diets containing phytase. Phytase exerted an extra-phosphoric effect on promoting pig's growth and improved the P dose-responses for ADG and G : F.

Abstract
OBJECTIVE To investigate the spatio-temporal characteristics of Oncomelania hupensis snails along the Jiangsu section of the Yangtze River, so as to provide evidence for eliminating schistosomiasis and formulating precision control measures in Jiangsu Province. METHODS A total of 75 marshlands were randomly sampled from Nanjing, Zhenjiang and Yangzhou cities along the Jiangsu section of the Yangtze River basin, and the spatio-temporal distribution and changing patterns of O. hupensis snails were investigated using the spatial autocorrelation analysis, kernel density analysis and hotspot analysis during the period from 2015 through 2017. RESULTS There was a spatial autocorrelation in the mean snail density along the Jiangsu section of the Yangtze River basin during the period from 2015 through 2017. The number of living snails and the density of living snails showed an overall decline in Yangzhou City; however, both showed a slight increase in 2016. Kernel density analysis and hotspot analysis showed that the hotspots of living snails were located in the regions neighboring the marshlands at the Yangzhou-Zhenjiang boundary areas along the Jiangsu section of the Yangtze River basin. CONCLUSIONS There is a spatial autocorrelation in the snail distribution with hotspots along the Jiangsu section of the Yangtze River basin, and the surveillance of snails should not be neglected in the marshlands in Jiangsu Province.

Abstract
Objective: To investigate the association between edentulism and cognition in people aged 50 and over in China. Methods: Cross-sectional data was collected from the first wave of World Health Organization Study on global AGEing and adult health in China, among people aged 50 and over in China. A comprehensive cognitive test was used to assess cognitive functions, including verbal recall (VR), verbal fluency (VF), forward digit span (FDS) and backward digit span (BDS) among the subjects. Association between edentulism and cognition was examined by a two-level (individual level and community level) linear model. Results: A total of 12 843 individuals aged 50 years and over were included for analysis, with an average age of (63.0±9.3) years. The overall prevalence of edentulism was 11.0%. The edentulous adults had lower mean scores of VR (4.55), VF (10.88), FDS (6.25), BDS (2.96) and overall cognition (49.15) (P<0.001). Edentulism was negatively associated with VR (β=-0.216, 95%CI: -0.370 - -0.062), FDS (β=-0.186, 95%CI: -0.293 - -0.078) and overall cognition (β=-1.703, 95%CI: -3.025 - -0.381) after adjusted for age, sex, residence, education level, marital status, household income, co-morbidity of chronic conditions, BMI, smoking and drinking alcohol. Conclusion: Edentulism was related with lower cognition level in people aged 50 and over in China.

Abstract
Objective: To investigate the association between sleep duration and frailty among people aged 50 years and over. Methods: Cross-sectional data was collected from the first wave of World Health Organization Study on global AGEing and adult health in China. Frailty index was constructed on the proportion of deficits, out of the 40 variables. A two-level (individual level and community level) linear model was performed to identify the related factors on frailty. All the models were stratified by age, gender, residence (urban/rural). Restricted cubic spline was performed to graphically evaluate the dose-response association between self-reported sleep duration and frailty. Results: A total of 13 175 individuals aged 50 years and over participated in this study. Without adjusting on any confounding factors, shorter or longer sleep duration significantly increased the risk of weakness compared with normal sleep time (OR=2.05, 95%CI: 1.71-2.44; OR=1.35, 95%CI: 1.12-1.63). After adjusting for confounding factors such as gender, age, residence, education, family assets, vegetable, smoking, drinking and physical activity, a positive association between short sleep duration and frailty was noticed compared with normal sleep time (aOR=1.60, 95%CI: 1.27-2.01). The results of stratified analysis on sex, age and urban and rural areas showed that, after adjusting for gender, age, residence, education level, family assets, intake of vegetables and fruits, smoking, drinking and physical activity, only shorter sleep duration was positively correlated with the risk of weakness. In addition, among people aged 65 years and over, adjusted for confounding factors, the risk of weakness increased by 91%, compared with normal sleep time (aOR=1.91, 95%CI: 1.46-2.49). The dose-response curve also showed that the sleep duration and frailty present an approximate "U" shaped relationship. Conclusion: Short sleep duration might be associated with frailty.

Abstract
Objective: To examine the association between long-term exposure to ambient PM(2.5) combined with indoor air pollution and handgrip strength among people aged 50 and over. Methods: Data were from the first wave of World Health Organization Study on global AGEing and adult health in China. Ambient annual concentration of PM(2.5) was estimated by using the satellite data we also investigated the use of fuels and chimneys as indoor air pollution. A two-level (individual level and community level) linear model was applied to examine the association between long-term exposure to ambient PM(2.5) combined with indoor air pollution and the handgrip strength. Results: A total of 13 175 individuals aged 50 years and over were included for analysis. The handgrip strength was (26.67±0.54) kg. Ambient PM(2.5) was found to be significantly associated with the risk of decreased handgrip strength. Outdoor PM(2.5) concentration was negatively correlated with handgrip strength (β=-0.23, 95%CI: -0.31 - -0.14) decrease in handgrip strength after adjusting for gender, age, residence, education, household assets, intake of vegetables and fruits, smoking and drinking, physical activity. In rural area, compared to those who used solid fuel, use of clean fuel increased (β=1.41, 95%CI: 0.36-2.46) handgrip strength. But in urban area, we did not find any statistically significant association between the use of clean fuel and handgrip strength (β=0.19, 95%CI: -0.95-1.32). Conclusion: This study found that long-term exposure to ambient PM(2.5) combined with indoor air pollution was significantly associated with low handgrip strength among people aged 50 years and over, this suggested that ambient PM(2.5) might serve as one of the risk factors for low physical function seen in the people aged 50 years and over.

Abstract
With accelerating and rapid ageing in China, there is an urgent need to collect reliable, valid and cross-nationally comparable data on health in the elderly to provide basis for richer and empirical analysis on the changing health over one's life course and compression of morbidity. To meet the demands of this growing special population, planning and preparing on related social protection mechanisms (health and pension systems) should also based on evidence-based decision-making process. Based on long-term follow-up, large scale cohort study is indispensible for the etiology of common chronic diseases and disabling conditions. This study aims to introduce the background, project objectives, contents, baseline characteristics, strength and weakness as well as prospect, related to the Study on global AGEing and adult health in China.

Abstract
Abstract
Background
Cumulative evidences have shown that IL-6 in atrium might play an important role in the pathogenesis of postoperative AF (POAF) via activation of atrial fibrosis in patients undergoing CABG. However, whether atria produces IL-6 after the stimulation of CABG and its causal relationship with spontaneous POAF (sPOAF) and its specific pathways is still unclear.
Purpose
To test the hypothesis that atrium will produce IL-6 after CABG and causes sustained sPOAF (ssPOAF) through activating pSTAT3-mediated fibroblast proliferation.
Methods
To determine the causal relationship between IL-6 and sPOAF, IL-6−/− and wild type (WT) mice were both divided into three groups (10 mice/group): CABG group (NAI, mimic CABG), anti-inflammatory group (AI, mimic CABG with pericardial administration of methylprednisolone for 3 days via chest tube), and control group (anesthesia only). Mice were monitored for ssPOAF for 7 days using implanted telemetry device. Another two sets of mice, using the same models mentioned above, were euthanatized at 48th hours postoperatively. The atria of one set animals were excised and separated into pericardium (PC), pulmonary vein (PV), left atrium (LA), and right atrium (RA) and cultured for 4 hours. IL-6 levels in the supernatant were measured at 10 min and 4 hours of culture using ELISA test. The region producing the largest amount of IL-6 in the other set of animals was harvested for analyzing expressions of IL-6, pSTAT3/STAT3, connexin 43 and 40, fibroblast deposition, and collagen I and III. Path analysis was performed to determine the causal relationship of CABG induced IL-6 release, pSTAT3/fibroblast signaling, and the onset of ssPOAF.
Results
40% NAI-WT mice developed ssPOAF (Figure 1A) which was completely protected in IL-6−/− and AI groups. IL-6 was produced by all 4 atrial regions at 4hrs after CABG stimulation with the LA producing the highest amount. Western blotting (Figure 1B), RT-CPR, Masson staining, and immunofluorescence all showed a significantly upregulation of IL-6, pSTAT3/STAT3, fibroblasts, collagen I and III, and downregulation of Cx40 an 43 in NAI-WT mice, but not in IL-6−/− and AI mice. IL-6 was colocalized with vimentin to a large extent in cytoplasm (Figure 1C). IL-6 had strong positive correlation with pSTAT3/STAT3, collagen I and III (all r>0.700, P<0.001), moderate and weak negative correlation with Cx40 and 43 (r=−0.505, P<0.001; r=−0.307, P=0.048, respectively). Path analysis (Figure 1D) revealed that every 1 unit increase in IL-6 upregulated a 0.589 unit increase in ssPOAF, which was mediated by pSTAT3/collagen indirectly and collagen I/ collagen III directly.
Conclusion
Our study, for the first time, to the best of our knowledge, established a novel pathophysiological role of IL-6/pSTAT3/fibroblast signaling in the pathogenesis of ssPOAF and demonstrated that inhibition of atrial IL-6 might be a potential novel sPOAF prevention strategy.

Abstract
Objective: To conduct a viral pathogen surveillance program on pediatric inpatients less than five years old with acute gastroenteritis in Shanghai and to better understand the pathogenic spectrum and molecular features in the target population, for setting up programs on control, prevention, medication and vaccine applications of the diseases. Methods: Fecal samples were collected from inpatients less than 5 years old who were admitted to a pediatric hospital for having acute gastroenteritis. Information related to demographic, clinical and epidemiological features of the patients was also collected. Laboratory assays including ELISA, real-time PCR and nested PCR, were performed to detect the presence of pathogens as rotavirus, calicivirus, astrovirus and adenovirus. Results: A total of 1 018 samples were collected (male 671 and 347 female), with the positive detection rate as 40.57% which peaked from autumn till winter, annually. Calicivirus and rotavirus A presented with the highest detection rates (24.75% and 13.95% respectively). The lowest detection rate was found in the 0-6 month-olds (32.20%). 65% of the patients with positive virus had received antibiotic treatment prior to the hospitalization. However, no statistically significant difference was seen, regarding the rates of antibiotic medication in the virus positive or negative populations (P>0.05). Data from the Rotavirus genotype analysis revealed that G9P[8] genotype was the predominant strain, and causing majority of rotavirus infections in all the age groups. Conclusions: Among the inpatients under 5 years of age in Shanghai, the positive detection rate for Calicivirus was higher than that for rotavirus group A, suggesting the necessity to carefully monitor the changes regarding the pathogenic spectrum and subtypes of the virus. Antibiotics should also be attentively administered, together with the development of suitable vaccine.
