Abstract
Objective: To understand the awareness of smoking hazards and intention of smoking concession in residents aged 18-65 years in Beijing, and provide scientific evidence for the development and improvement of tobacco control policies and measures. Methods: Data were collected from the 2017 Beijing Non-communicable and Chronic Disease surveillance. A multi-stage stratified cluster sampling method was used to take samples from 165 communities in 16 districts of Beijing. Logistic regression was used to analyze the influencing factors. Results: Among 11 594 participants, 49.93% had no intention of smoking concession. The percentage of refusing smoking concession was higher in men (50.39%) than in women (43.01%), the difference was significant ( χ(2)=14.211, P=0.002), and higher in suburban residents (56.78%) than in urban residents (45.30%), the difference was significant ( χ(2)=51.977, P<0.001). For the smoking cessation motivation, "illness" was the reason for more former smokers (29.88%) compared with current smokers (11.50%), the difference was significant ( χ(2)=85.865, P<0.001). The awareness rates of smoking hazards was higher in women (34.97%) than in men (32.63%), the difference was significant (Z=5.612, P<0.001), higher in suburban residents (35.44%) than in urban residents (33.03%), the difference was significant (Z=-3.734, P<0.001), and higher in never smokers (35.15%) than in smokers (30.06%), the difference was significant ( χ(2)=62.277, P=0.005). Multiple logistic regression analysis results showed people with general awareness (OR=0.61, 95%CI: 0.39-0.94) and poor awareness (OR=0.67, 95%CI: 0.50-0.90) of smoking hazards were less likely to quit smoking and people with general awareness (OR=0.64, 95%CI: 0.53-0.76) and poor awareness (OR=0.87, 95%CI: 0.78-0.98) of smoking hazards were more likely to smoke. Conclusions: Smokers aged 18-65 in Beijing had low willingness for smoking cessation. Health problem was main consideration for smoking cessation. Never-smokers had better awareness of smoking hazards than smokers, and the awareness of smoking hazards was an influencing factor of smoking status.

Abstract
AIM Research on prevention and cure of banana wilt is important to ensure the healthy development of the banana industry. In this study, antifungal mechanism of Streptomyces ma. FS-4 on fusarium wilt of banana was investigated. METHODS AND RESULTS The physiological strain of banana fusarium pathogen Fusarium oxysporum f. sp. cubense Race 4 (FOC.4) was used as the target fungus, and the antifungal mechanism of the crude extract of Streptomyces ma. FS-4 was investigated. Eighteen different compounds identified by gas chromatography-mass spectrometry were composed of aldehydes, methyl, hydrocarbons, amides, esters and acids. FS-4 significantly inhibited the spore germination of the target fungi, with an EC50 of 22·78 μg ml-1 . After treatment with 100 μg ml-1 FS-4 crude extract, the N-acetylglucosamine content in the mycelium increased 1·95-fold. However, the extract had no significant effect on β-1,3-glucanase. At the FS-4 crude extract dose of 100 μg ml-1 , the total sugar and protein contents decreased by 28·6 and 29·1% respectively, and the fat content was 41·3%. FS-4 significantly inhibited the activity of the mitochondrial complex III of Foc4, which was reduced by 52·45%. Moreover FS-4 reduced the activity of succinate dehydrogenase, a key enzyme in the Krebs cycle, by 60·2%. However, FS-4 had no significant effect on malate dehydrogenase. The membrane potential on the mitochondrial inner membrane was significantly reduced at the test concentration of 100 μg ml-1 . ROS gradually accumulated in the Foc4 hypha, and the burst was 3·97 times higher than the control. CONCLUSIONS This study demonstrated that the antifungal mechanism of Streptomyces ma. FS-4 against Foc4 includes the destruction of the plasma membrane and mitochondrial dysfunction and finally induction of cell apoptosis. SIGNIFICANCE AND IMPACT OF THE STUDY These results may indicate the prevention and control of banana wilt, which is of great significance to the healthy development of banana industry system.

Objective response of first-line chemotherapy of triple-negative breast cancer translates into survival benefit: an analysis in an independent, prospective clinical trial and a real-world setting. Neoplasma 2020; 67:1400-1408.

Abstract
This study sought to assess whether the objective response (OR, including complete response and partial response) of first-line chemotherapy can predict overall survival (OS) for patients with metastatic triple-negative breast cancer (mTNBC) in both clinical trial and a real-world setting. The survival predictable parameters were assessed in two independent cohorts, the training cohort of 236 patients as part of a phase 3 trial (CBCSG006, Trial registration number NCT0128762) and the validation cohort of 360 patients from the real-world setting. Univariable and multivariable Cox proportional hazard models were applied to explore associations with progression-free survival and OS in the training cohort and then in the validation cohort. OR (OR vs non-OR, HR, 0.438, p<0.001) together with Eastern Cooperative Oncology Group (ECOG) performance status, disease-free survival, number of metastatic organ sites and platinum-based chemotherapy used as first-line chemotherapy were observed to be independent prognostic factors for progression-free survival (PFS), and OR (OR vs non-OR, HR, 0.602, p=0.002) together with ECOG score, disease-free survival, number of metastatic organ sites and previous anthracycline and/or taxane treatment were observed to be independent predictive factors for OS in the training cohort. These predictors were confirmed in the validation cohort. For OR and non-OR group, median OS was 23.72 and 13.83 months in the training cohort (HR, 0.637, p=0.002), and 21.95 and 13.80 months in the validation cohort (HR, 0.608, p<0.001), respectively. By adding OR in the OS predictors, the concordance index (C-index) improved from 0.622 to 0.645 in the training cohort and 0.653 to 0.675 in the validation cohort. PFS and OS of mTNBC can be predicted by OR status with any regimen of first-line chemotherapy in an independent prospective clinical trial and a real-world setting. Therefore, TNBC, not like other subtypes of breast cancer, may be in need of combination chemotherapy or intense chemotherapy to achieve a high response rate for survival.

Abstract
Phytotoxins are widely found in plant pathogens. In recent years, many diseases caused by Neopestalotiopsis clavispora have been reported. To better understand the pathogenicity of N. clavispora, a solid fermentation strategy was employed to isolate and identify virulence factors afritoxinone B, afritoxinone A and oxysporone. The phytotoxic activities of these toxins were evaluated. Oxysporone exhibited high levels of phytotoxic activity after 72 h and the lesion area ranged from 21.5-84.3 mm2 after 9 days of treatment. The phytotoxic activities of the other two compounds were lower than that for oxysporone. The phytotoxic activity towards non-host organisms was also assessed for the three analyzed compounds; phytotoxic activity was observed in each case. Based on these results, we conclude that oxysporone is the main virulence factor in N. clavispora. We also suggest that each of the three compounds were non-host-specific toxins (NHST). To our knowledge, this is the first study to analyze phytotoxins produced by N. clavispora.

Abstract
Background:Opioids are not recommended as first-line treatments for chronic pain management in osteoarthritis (OA), but recent data suggest they are commonly used in routine practice in North America and northern Europe.Objectives:To characterise the secular trends of opioid and strong opioids use in patients with incident OA from 2007 to 2016, and to explore the impact of patient characteristics on the use of opioid/s for OA.Methods:Data was obtained from the SIDIAP (The System for the Development of Research in Primary Care) database, which contains primary care records and pharmacy dispensing data for 80 % of the population in Catalonia (~ 6 million people). All persons aged 18 or older at the beginning of each calendar year with an incident OA diagnosis (including both peripheral and central joints) in the study period were included. Index date was the date of first OA diagnosis, and the observation period of opioid use was 1-year after index date. Opioids considered included codeine, tramadol, fentanyl, and morphine, with the latter three classified as strong opioids. The period prevalence of any opioid use was estimated in whole and sub-population stratified by sex, age, socio-economic status (U1 – U5, higher values of the indicator equivalent to deprivation) and residence area (rural/urban).Results:The 1-year prevalence of any opioid use among incident OA patients was around 15% from 2007 to 2012. After that, this figure grew by 10% approaching 25% in 2016. However, strong opioid use increased continuously to nearly triple, from 8% in 2007 to 20% in 2016. The different subgroups followed similar trends over time, with women 4% higher than men, oldest 10% higher than youngest, most deprived 6% higher than least deprived, and rural 1% higher than urban.Conclusion:The use of opioids (and especially strong opioids) has substantially increased in recent years among newly diagnosed OA patients in Catalonia. Our findings call for urgent action for safe opioid prescribing to avoid opioid abuse in OA patients especially amongst older women living in deprived areas.Figure 1.Trends of 1-year prevalence of opioid/s use among incident OA patients, whole and subgroup population.Disclosure of Interests:Junqing Xie: None declared, Aleksandra Turkiewicz: None declared, Gary Collins: None declared, Martin Englund Consultant of: Advisory Board 1 day (2019) Pfizer (Tanezumab)., Victoria Y Strauss: None declared, Carlen Reyes: None declared, Daniel Prieto-Alhambra Grant/research support from: Professor Prieto-Alhambra has received research Grants from AMGEN, UCB Biopharma and Les Laboratoires Servier, Consultant of: DPA’s department has received fees for consultancy services from UCB Biopharma, Speakers bureau: DPA’s department has received fees for speaker and advisory board membership services from Amgen

Abstract
Background:Abnormal liver function can be seen in not only hepatitis B virus infection (HBV), hepatitis C virus infection (HCV), hepatic carcinoma (HCC), but also in primary biliary cirrhosis (PBC), autoimmune hepatitis (AIH), and systemic autoimmune rheumatic diseases (SARD). Antinuclear antibody (ANA) testing using indirect immunofluorescence assay (IIFA) is a common and economical method which contributes to detect SARD and autoimmune liver diseases [1].Objectives:Our objective was to investigate ANA positivity, titers and their patterns in multiple liver diseases, including PBC, AIH, HBV, HCV, and HCC, compared to healthy controls (HC).Methods:2537 patients with SARD, 137 PBC cases, 57 AIH cases, 3420 HBV cases, 769 HCV cases, 268 HCC cases, and 1073 HC were retrospectively assessed. The titers and patterns of ANA were detected with the IIFA method.Results:ANA positivity rate was considerably discernible between these diseases, which is 90.1% in SARD, 93.4% in PBC, 49.1% in AIH, 19.1% in HBV, 13.9% in HCV and 23.5% in HCC. Moreover, only 4.9% of HCC cases, 2.5% of HBV patients and 1.6% of HCV patients had an ANA titer ≥ 1:320. The mixed pattern which composed of at least two patterns majorly lied in PBC. AC-15 and AC-21 was frequently related to liver diseases; the former pattern was more frequently found in AIH (84.2%) and PBC (8.8%), and the latter pattern was easily seen in PBC (62.2%) and HCC (22.6%). The positive rate of ANA in HC was 12.2% and its major pattern was AC-2.Conclusion:There are differences in ANA positivity among patients with SARD and various liver diseases. Some mixed patterns may provide important evidence for the diagnosis of PBC. Clinicians should pay attention to ANA patterns and titer during the interpretation of this test.References:[1]Damoiseaux J, Andrade L, Carballo OG, Conrad K, Francescantonio P, Fritzler MJ, Garcia DLTI, Herold M, Klotz W, Cruvinel WM, Mimori T, von Muhlen C, Satoh M, Chan EK, (2019) Clinical relevance of HEp-2 indirect immunofluorescent patterns: the International Consensus on ANA patterns (ICAP) perspective.

Abstract
Background:Takayasu arteritis (TA) refers to chronic progressive non-specific inflammation that involves the aorta and its main branches, causing stenosis and occlusion of arteries in different parts, and ischemic manifestations in the corresponding parts. A variety of immune dysfunctions are involved in the occurrence and development of TA(1)Recent studies have shown that Th17/Treg imbalance plays an important role in the pathogenesis of Takayasu’s arteritis, in which T help 17 cells (Th17) cells are up-regulated in TA patients(2). Th17 cells are closely related to Treg cells during differentiation. There are few studies on the expression level of CD4+CD25+FOX3+T lymphocyte (Treg) cells. This study aims to study the clinical significance of Treg cell expression in peripheral blood of patients with Takayasu’s arteritis.Objectives:To analyze the levels of circulating lymphocyte subsets and serum cytokines in patients with takayasu arteritis (TA), and explore the relationship between their changes and TA disease activity.Methods:A total of 46 TA patients and 43 gender-age-matched healthy controls were enrolled. According to the NIH standard, 30 patients were in active disease. Flow cytometry was used to detect the absolute numbers and ratios of Th1, Th2, Th17 and Treg cells in peripheral blood of all subjects. Magnetic bead-based multiplex immunoassay was used to detect cytokines and statistical analysis was performed.Results:Compared with the healthy controls, the absolute number and proportion of peripheral Treg cells of TA patients significantly decreased while those of Th17 cells increased significantly, leading to the increased ratio of Th17 / Treg. Compared with the inactive group, the TA active group had significantly increased IL-6 and TNF-α, and there was no significant difference in the expression of Th17 cells and Treg cells.Conclusion:In peripheral blood of TA patients, Treg cells decreased, while Th17 cells increased as compared with healthay controls, leading to an imbalance between Th17 and Treg cells. The levels of IL-6 and TNF-α were related to disease activity.References:[1]Russo, R.A.G. and M.M. Katsicas, Takayasu Arteritis. Front Pediatr, 2018. 6: p. 265.[2]Misra, D.P., S. Chaurasia, and R.

Abstract
Introduction
As a common but modifiable chronic condition, obstructive sleep apnea (OSA) has been identified as the top secondary cause of many other diseases including cardiovascular diseases and type 2 diabetes. Diagnosing and managing OSA provides neurological, cardiovascular and metabolic benefits, however real-world studies indicate disconnections between evidence and outcomes. Using an engagement approach and qualitative design, this project aims to better understand care and research gaps in OSA in a community healthcare setting.
Methods: Methods
Patient and family representatives were identified and recruited through OSA support meetings hosted by MultiCare Sleep Medicine Centers, to form a board of 12, with three key patient advocates. Six meetings, each facilitated by one or two members of the board, were held to encourage focus group discussion and accommodate interactive conversations on the topic. Discussions were audio recorded and edited to exclude patients’ identifiable information, then transcribed. Manual open coding was completed by two coders for each transcription to develop a codebook, followed by auto-coding and inductive content analysis using Nvivo 11.
Results
All enrolled patients had diagnosed moderate-to-severe OSA and were prescribed with continuous positive airway pressure (CPAP) therapy. Two participants were African American and one was multiethnic. Patients’ age ranged from early 30s to 80s. Seven main themes were identified: OSA diagnostic issues; treatment experiences and options; comorbidities; patient community and support needs; long-term management challenges beyond “compliance”; knowledge of OSA, CPAP and care; and patient-driven research. The first few weeks after CPAP initiation appeared to be a critical time window that impacted patients’ adaptation and use.
Conclusion
Our study revealed barriers and facilitators in OSA diagnosis and treatment. Results showed highly prevalent chronic co-morbidities and the needs to care for patients in the comorbid scenario. It was highlighted that a paradigm of patient-centered care and research is lacking and warranted. Participants also called for better coordination between sleep medicine, primary care, other specialists, durable device suppliers and insurance. Key research efforts are expected to focus on the first 30-day post CPAP dispense to improve compliance.

Abstract
Abstract
Introduction
Patients with severe restrictive ventilatory defect (RVD) have hypoxemia and a high risk of pulmonary hypertension (PHTN). Sleep apnea (SA) aggravates the severity of nocturnal desaturation significantly. The aim of this study was to investigate the severity of hypoxemia and prevalence of PHTN in patient with the overlap syndrome (OS) of RVD and SA.
Methods
Patients referred for both sleep test and spirometry for suspected SA and RVD or obstructive ventilatory defect (OVD) were recruited prospectively from January-December, 2018. SA was determined by an apnea-hypopnea index ≥5/h; mean nocturnal oxygen saturation (meanSaO2), minimum oxygen saturation (minSaO2), saturation lower than 90% (T90) were calculated automatically. RVD was diagnosed in the presence of forced expiratory volume in the first second/forced vital capacity (FVC) >0.7 and FVC<80% predicted value. PHTN was defined by systolic pulmonary arterial pressure (SPAP) ≥ 50mmHg, documented by noninvasive transthoracic echocardiography. Patients with PHTN secondary to extrapulmonary factors were excluded.
Results
Of 65 patients who completed the investigation, 16 (24.6%) subjects were diagnosed with isolated SA (without RVD or OVD), and 28 (43.1%) subjects were verified to have RVD, in which 22 (78.6%) were diagnosed with OS and 6 (21.4%) presented as isolated RVD. Patients with OS vs. those with isolated RVD had lower minSaO2 (78.3% vs. 88.7%, p=0.003) and meanSaO2 (91.5% vs. 95.8%, p=0.007) but higher T90 (37.2% vs. 0.3%, p=0.009). Patients with OS vs. those with isolated RVD or with isolated SA had higher SPAP (62.6 mmHg vs. 45.3 mmHg or 35.9 mmHg, p=0.334 or p=0.016 respectively). Higher proportion of patients with OS were diagnosed with PHTN than those with isolated RVD or isolated SA (8 [36.4%] vs. 1 [16%] or 1 [6.25%], p=0.360 or p=0.031, respectively). T90 was the only polysomnographic data associated with the prevalence of PHTN after adjusting for age and sex (OR 4.90, 95% CI 1.23-25.56, p=0.023).
Conclusion
Patients with the OS of RVD and SA had high odds of PHTN, which is probably associated with severe hypoxemia. Further investigation is needed to discern whether therapeutic strategies toward OS might eliminate PHTN in this cohort.

Abstract
Introduction
To systematically examine the association between sleep duration and metabolic syndrome (Mets) risk in cross-sectional and prospective cohort studies.
Methods
Data were collected from 36 cross-sectional and 9 longitudinal studies with a total of 164799 MetS subjects and 430895 controls. Odds ratios (ORs) for MetS in cross-sectional studies and risk ratios (RRs) for incident MetS were calculated through meta-analyses of adjusted data from individual studies. Subgroup analyses were performed to investigate the association between MetS and the duration of short-and-long sleep.
Results
Short sleep duration was significantly associated with increased prevalent MetS (OR= 1.11, 95% CI =1.05-1.18) and incident MetS (RR= 1.28, 95% CI =1.07-1.53,) in cross-sectional and longitudinal studies, respectively. Furthermore, long sleep duration was significantly associated with increased prevalent MetS in cross-sectional studies (OR= 1.14, 95% CI =1.05-1.23), rather than incident MetS (RR= 1.16, 95% CI =0.95-1.41) in longitudinal studies. Interestingly, the association between long sleep and prevalent MetS was found in sleep duration defined by 24-hour sleep (including naps) rather than nighttime sleep. In cross-sectional studies, pooled odds for MetS were 1.36 (95% CI=1.04-1.78, I2=83.3%) in ≤ 5 hours, 1.09 (95% CI=1.02-1.16, I2=67.8%) in ≤6 hours, 1.01 (95% CI=0.93-1.10, I2=24.9%) in <7 hours, 1.11 (95% CI=1.02-1.21, I2=67.0%) in ≥9 hours and 1.31 (95% CI=1.22-1.40, I2=0%) in ≥10 hours, respectively. The association of short sleep and MetS was stronger in young and middle age adults, but lost in adults age >60 years.
Conclusion
Our findings suggest 1) a “U-shape” relationship between sleep duration and MetS in cross-sectional studies and 2) association between short sleep duration, but not long sleep duration with incident MetS. Future studies should shed light on the underlying mechanisms related to the association between sleep duration and MetS and examine if normalizing sleep duration reduces MetS risk in the general population.

Abstract
The cAMP responsive element binding protein (CREB)-regulated transcription coactivator 3 (CRTC3) is a member of the CRTC protein family and plays an important role in energy metabolism. The aim of this study was to determine if the expression of porcine CRTC3 is related to intramuscular fat (IMF) deposition and meat quality in Heigai pigs (a local fatty breed in China) and Duroc × Landrace × Yorkshire (DLY) pigs (a lean crossbred pig widely cultured in China). In addition, the effect of ectopic expression of CRTC3 on gene expression in porcine IMF adipocytes was also examined. Our results showed that Heigai pigs had lower lean percentage, thicker back fat thickness and smaller loin muscle area than DLY pigs. Compared with DLY pigs, Heigai pigs had higher marbling scores, better meat color and higher IMF contents and triglyceride concentrations. Higher levels of oxidative metabolic enzyme and expression of the slow oxidative muscle fiber-related genes were observed in longissimus dorsi muscle and psoas major muscle (P < 0.05) from Heigai pigs. Notably, CRTC3 and adipocyte-specific marker genes were highly expressed in muscle tissues of Heigai pigs. The expression of lipolysis-related genes ATGL and HSL were lower in Heigai muscles. Moreover, forced expression of CRTC3 promoted lipid accumulation and increased the expression of PPARγ, C/EBPα, leptin and FABP4 (P < 0.05), whereas it decreased the expression of ATGL and HSL in IMF adipocytes. These results suggest that CRTC3 expression is associated with lipid accumulation and IMF deposition in pigs.

Abstract
OBJECTIVE Acute lung disease is characterized by inflammation. This research aimed to investigate effect of trichostatin A (TSA) on microRNA-146a (miR-146a) and tumor necrosis factor α (TNF-α) in lipopolysaccharide (LPS)-induced alveolar macrophage injury model. MATERIALS AND METHODS Rat alveolar macrophage, NR8383, was cultured and induced using LPS to establish acute lung injury model in vitro level. Cell Counting Kit-8 (CCK-8) assay was used to determine cell viability of NR8383 cells. TSA was administrated to LPS-induced NR8383 cells. Quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) assay was utilized to evaluate TNF-α and miR-146a mRNA expression in LPS and/or TSA treated NR8383 cells. Enzyme-link immunosorbent assay (ELISA) was used to examine TNF-α levels. RESULTS This study selected 1 ng/ml and 10 ng/ml TSA as the optimal concentrations for treating NR8383 cells. LPS-induced acute lung injury model was successfully established. TSA administration significantly enhanced accounts of LPS-stimulated NR8383 cells. LPS induction significantly increased miR-146a mRNA expression in NR8383 cells compared to NR8383 cells (p<0.05). TSA administration significantly reduced the levels of TNF-α in LPS-induced NR8383 cells compared to those in LPS-induced NR8383 cells (p<0.05). TSA administration significantly enhanced miR-146a expression in LPS-induced NR8383 cells compared to that in LPS-induced NR8383 cells (p<0.05). CONCLUSIONS TSA administration exerted anti-inflammation functions in LPS-induced acute lung injury model in vitro, which might be triggered by inhibiting TNF-α molecule and upregulating miR-146a expression. The present data hint that TSA could be considered as a potential therapeutic agent for treating acute lung injury.

Abstract
STUDY OBJECTIVES A major challenge in treating insomnia is to find effective medicines with fewer side effects. Activation of G-protein-gated inward rectifying K+ channels (GIRKs) by GABAB agonists baclofen or γ-hydroxybutyric acid (GHB) promotes nonrapid eye movement (NREM) sleep and consolidates sleep. However, baclofen has poor brain penetration, GHB possesses abuse liability, and in rodents both drugs cause spike-wave discharges (SWDs), an absence seizure activity. We tested the hypothesis that direct GIRK activation promotes sleep without inducing SWD using ML297, a potent and selective GIRK activator. METHODS Whole-cell patch-clamp recordings from hypocretin/orexin or hippocampal neurons in mouse brain slices were made to study neuronal excitability and synaptic activity; spontaneous activity, locomotion, contextual and tone-conditioned memory, and novel object recognition were assessed. Electroencephalogram/electromyogram (EEG/EMG) recordings were used to study GIRK modulation of sleep. RESULTS ML297, like baclofen, caused membrane hyperpolarization, decreased input resistance, and blockade of spontaneous action potentials. Unlike baclofen, ML297 (5-10 µM) did not cause significant depression of postsynaptic excitatory and inhibitory currents (EPSCs-IPSCs), indicating preferential postsynaptic inhibition. ML297 (30 mg/kg, i.p.) inhibited wake activity and locomotion, and preferentially increased NREM sleep without altering EEG delta power, REM sleep, inducing SWDs, or impairing conditioned memory and novel object recognition. CONCLUSIONS This study finds that direct activation of neuronal GIRK channels modulates postsynaptic membrane excitability and prolongs NREM sleep without changing sleep intensity, inducing SWDs, or impairing memory in rodents. These results suggest that direct GIRK activation with a selective compound may present an innovative approach for the treatment of chronic insomnia.

Abstract
SummaryEpistaxis is a common condition that can be associated with significant morbidity, and it places a considerable burden on our healthcare system. In China, a draft guidelines for diagnosis and treatment of epistaxis was released in 2015. In UK, a national audit of management for epistaxis was promulgated in 2016, followed by multidisciplinary consensus recommendations on the hospital management of epistaxis in 2017. Here, we compared the management of diagnosis and treatment for epistaxis between China and UK in five clinical aspects, including initial assessment, cautery, intranasal agents, antithrombotic therapy and hematological factors, as well as surgery and radiological intervention. The results demonstrate that the management recommendations in UK combined a wide-ranging review of the relevant literature with established and rigorous methods of guideline generation, while the guidelines in China is more specific on the procedures of diagnosis and treatment for epistaxis. The current discussion provides perspectives to improve the guidelines for epistaxis in China.

Abstract
Objective: To explore the prevalence of occupational musculoskeletal disorders (OMD) and its influencing factors among rural migrant workers in Tianjin, with the aim of developing strategies to improve the health condition of this specific population. Methods: Questionnaire survey was conducted among 415 rural migrant workers working in Tianjin about their fundamental state and occupational musculoskeletal disorders (OMD) during January 2015 to January 2016. Statistical methods were utilized to analyze the influencing factor. Results: A total of 415 rural migrant workers were investigated, in which young Young adults and low education level were in the majority of rural migrant workers. The prevalence of OMD for whole population, male and female were 28.92% (120/415), 33.06% (81/245) and 22.94% (39/170), respectively. Prevalence showed significant differences njin and workplace hygiene. Multivariate logistic regression analysis showed that the risks of OMD increased with age group, and decreased with higher education level. The risk of OMD among rural migrant workers with monthly income between 3000 to 5000 yuan was 2.26 times (95%CI: 1.37-3.75) higher than that of low-income workers (<3000 yuan per month). Workers engaged in housekeeping service had 2.28 times higher risk of OMD than those in manufacturing industry (95%CI: 1.06-4.89) . Conclusion: Prevalence of OMD among rural migrant workers is higher than that of general people. Age, education, monthly income, occupation are the independent influencing factors for OMD among rural migrant workers.

Abstract
OBJECTIVE We aimed to study changes and possible roles of epigenetic modification of candidate genes in the pathogenesis of bipolar disorder, and provide the basis for clinical diagnosis and analysis. PATIENTS AND METHODS A total of 150 patients with bipolar disorder were enrolled in this study from January 2014 to June 2015; also, 50 healthy subjects were enrolled as control group. The patients were followed up for 18 months and followed up once every 3 months to review the methylation status. The methylation status was examined before and after treatment, and the patients were followed up every 3 months after treatment, and the follow-up period was 18 months. RESULTS Compared with the healthy control group, there were 2075 CpG island aberrant methylation points in patients with bipolar disorder, which can be divided into 24 categories. Log-Ratio > 0.5 was used as the positive criteria, and COMT and PPIEL were identified as the genes associated with bipolar disorder. Compared with the control group, the levels of COMT and PPIEL gene methylation in the observation group were significantly higher (p < 0.05). There was no significant difference in the methylation level of COMT and PPIEL gene between the two groups (p > 0.05) after 12 months of treatment. CONCLUSIONS The methylation level of COMT and PPIEL gene is closely related to bipolar disorder.

Abstract
OBJECTIVE We aimed at investigating the functions of endothelial progenitor cells (EPCs) in the pathophysiology of coronary artery spasm (CAS) and coronary artery disease (CAD), as well as to evaluate the correlation of these diseases with the number and function of EPCs, the plasma concentration of vascular endothelial growth factor 165 (VEGF165) and stromal cell-derived factor 1 (SDF-1). PATIENTS AND METHODS Participants were recruited into three groups, CAS, CAD and the control. The number and functions of early EPCs and outgrowth endothelial cells (OECs) were determined in peripheral blood samples, and the endothelial function was evaluated by measuring endothelium-dependent flow-mediated vasodilation (FMD). RESULTS No differences of baseline characteristics were found among CAS, CAD, and the control groups. The OECs isolated from CAS and CAD exhibited significant decrease in the percentage of CD34+/CD45- population, OEC colony formation, OEC proliferation and OEC tubulogenesis, nitric oxide (NO) production, endothelial nitric oxide synthase (eNOS) activity, and the phosphorylation level at Ser1177 of eNOS, compared with OECs isolated from control participants. Meanwhile, FMD was significantly reduced in CAS and CAD (CAS, 4.1% ± 1.9%; CAD, 4.3% ± 1.8%; control, 11.2% ± 3.5%). FMD was positively correlated to OEC functions including NO production, eNOS phosphorylation, colony formation, and proliferation. No differences of plasma VEGF165 and SDF-1 concentrations were recorded among these three groups. Similarly, there was no correlation between plasma VEGF165 (and SDF-1) concentration and EPC number and function. CONCLUSIONS EPCs show the potential of repairing damaged endothelium in CAS and CAD.

Abstract
OBJECTIVE To investigate the related factors of soil-transmitted nematode infections in Chongqing City, so as to provide the basis for scientific prevention and treatment of the infections. METHODS From 2011 to 2015, the stool samples of residents of the surveillance sites in Chongqing City were collected every year, and the soil-transmitted nematode eggs were examined by the modified Kato-Katz thick smear method (three smears for a single stool sample). The respondents were surveyed by questionnaires, and the factors affecting soil-transmitted nematode infections were identified. RESULTS The prevalence of human soil-transmitted nematode infections were 6.44%, 7.30%, 6.85%, 6.93% and 5.56% in Chongqing City from 2011 to 2015, respectively. The more unclean drinking water and the lower frequency of washing hands after using the toilet were the risk factors for Ascaris lumbricoides infection. The more harmless toilets, the higher level of fertilizer application, the lower frequency of drinking raw water, and the lower frequency of food without washing were the protective factors for A. lumbricoides infection. CONCLUSIONS The local soil-transmitted nematode infections are at a low epidemic level in Chongqing City, and it is necessary to ad-here to the classified guidance, comprehensive prevention and further monitoring on the basis of health education, water and toilet improvement, and environmental sanitation improvement in order to consolidate the prevention and control achievements.

Abstract
C-type lectins are one of the pattern-recognition proteins involved in innate immunity in invertebrates. Although there are 16 C-type lectin genes that have been identified in the genome of Tribolium castaneum, their functions and mechanisms in innate immunity remain unknown. Here, we identified one C-type lectin orthologue, TcCTL6 (TC003708), by sequencing random clones from the cDNA library of the coleopteran beetle, T. castaneum. TcCTL6 contains a 654 bp open reading frame encoding a protein of 217 amino acids that includes a single carbohydrate-recognition domain. The expression of TcCTL6 was significantly induced by Escherichia coli, Staphylococcus aureus and stimulation with carbohydrates, including lipopolysaccharide and peptidoglycan. A binding assay suggested that the recombinant TcCTL6 not only bound to lipopolysaccharide and peptidoglycan but also bound to Gram-positive (S. aureus, Bacillus subtilis and Bacillus thuringiensis) and Gram-negative bacteria (E. coli and Pseudomonas aeruginosa) in the presence of calcium ions. Furthermore, when TcCTL6 was knocked down by RNA interference, four antimicrobial peptides (attacin1, attacin2, coleoptericin1 and coleoptericin2) were significantly decreased. These results demonstrate that TcCTL6 plays a vital role in the immune response towards pathogen infection by influencing the expression of antimicrobial peptides and the agglutination of bacteria in the presence of calcium ions in T. castaneum.

Abstract
OBJECTIVE To investigate the clinical characteristics, imaging changes and early diagnostic methods of neuropsychiatric systemic lupus erythematosus (NPSLE). METHODS Thirty-five SLE patients, of which 16 had overt neuropsychiatric symptoms, underwent examination for multiple autoantibodies, including anti-double-stranded DNA (anti-dsDNA) antibody, anti-nucleosome antibody, anti-cardiac-phospholipid antibody (aCL)-IgG, aCL-IgM, anti-β2-glycoprotein I antibody and anti-ribosomal P antibody, and the SLEDAI score of every patient was recorded. All patients further received neuropsychological tests, including the Mini-Mental State Examination, the Self-Rating Anxiety Scale and the Self-Rating Depression Scale. Imaging examination using 3D arterial spin labeling was performed on 3.0 T MRI scanners. After processing the 3D arterial spin labeling image, the cerebral blood flow map was obtained and the cerebral blood flow value was calculated. RESULTS The values of anti-dsDNA, anti-nucleosome antibody, aCL-IgG and anti-β2-glycoprotein I antibodies were significantly higher in the NPSLE group than those in the SLE group. The SLEDAI scores of the NPSLE group were significantly higher than those of the SLE group. There were no significant differences between the NPSLE group and the SLE group in the directional ability, memory, attention, numeracy, recall ability or language ability scores on the Mini-Mental State Examination scale. Furthermore, there were no symptoms of anxiety or depression in any of the patients, according to the Self-Rating Anxiety Scale and Self-Rating Depression Scale. In the 35 patients with SLE, decreases in blood perfusion were seen in some areas, and were unilateral and asymmetrically distributed. There was obvious asymmetry between sides in areas including the frontal lobe, temporal lobe, parietal lobe and occipital lobe. The incidence of perfusion decreases in frontal lobe in the NPSLE group was significantly higher than in the SLE group. CONCLUSION Neurological lesions in SLE patients can be detected by arterial spin labeling. Cerebral blood flow abnormalities may be helpful for the early diagnosis of neurological lesions in NPSLE.

Abstract
BACKGROUND Glioma is a type of tumor that occurs in the brain and accounts for almost 30 % of all brain and central nervous system tumors and 80 % of all malignant brain tumors. In this study, we investigate the role of cAMP response element-binding protein (CREB) in the progression of glioma. METHODS Tissue samples from glioma patients were collected and examined for expression of CREB and its correlation with tumor grades. CREB was then knocked down via siRNA to see if reduced expression of CREB affects cell proliferation and migration. Factors involved in cell cycles, adhesion and apoptosis were examined as well. Moreover, CRESP/CAS9 mediated knockout of CREB was conducted and athymic Nude mice model was used to investigate CREB's role in vivo. RESULTS The evaluated expression level of CREB in glioma patients was correlated with tumor grades. Knockdown of CREB via siRNA in glioma cell line U251 significantly inhibited the proliferation and migration of tumor cells. Moreover, CyclinD1 and Bcl-2 expression were reduced, as well as phosphorylation of IRK1/2 and AKT. Additionally, knockout of CREB via CRESP/CAS9 inhibited tumor formation of U251 cells in athymic Nude mice model. CONCLUSIONS In conclusion, our data suggest that over expression of CREB may contribute to progression of glioma and knockdown of CREB expression may serve as a novel target for therapy (Tab. 1, Fig. 6, Ref. 25).

Abstract
Objective: To investigate the clinical features and T lymphocytes subsets in patients with acquired immune deficiency syndrome (AIDS) and cytomegalovirus (CMV) infection. Methods: A total of 48 hospitalized patients with human immunodeficiency virus (HIV)-1/AIDS and CMV infections were recruited at Peking Union Medical College Hospital from Jan 2010 to Aug 2017. Their clinical features and immune function were retrospectively analyzed. Patients with only HIV/AIDS in previous study were recruited as controls. Results: All 48 patients were at C3 stage, including 36 men and 12 women. Five of them were younger than 30 years old, 33 cases within 31-50 years old, and 10 cases older than 50 years old. Thirty-five patients had CD(4)(+)T lymphocytes ≤ 50 cells/μl, 7 cases with CD(4)(+)T cells 51-100/μl, 3 cases with 101-200 cells/μl, and 3 cases over 200 cells/μl. As to CMV infections, there were 31 cases of CMV viremia, 1 case of CMV encephalitis, 1 case of CMV enteritis, 5 cases of CMV pneumonia, and 9 cases of CMV retinitis. Other opportunistic infections were also common including 16 cases of pneumocystis pneumonia, 9 cases of tuberculosis, 5 cases of syphilis, 18 cases of digestive tract fungal infections, 8 cases of pulmonary fungal infections, 2 cases of EB virus infections, 2 cases of HIV encephalopathy/progressive multifocal leukoencephalopathy (PML), 3 cases of cryptococcal meningitis, 1 case of toxoplasma infection. In group of both CMV and HIV/AIDS infections, 100% patients had inverted CD(4)(+)/CD(8)(+) ratio. The immune activation marker CD(8)(+)CD(38)(+)/CD(8)(+) was higher (61.6%-98.8%) with a median value of 91.2% in 40 patients. HLA-DR(+)CD(8)(+)/CD(8)(+), another marker for T cell activation, was 25.5%-98.0% in 44 patients with a median value of 60.3%. Thirty-six patients had both immune activation markers positive. There was no significant difference in counts of B cells, natural killer cells, CD(4)(+) T cells, CD(8)(+) T cells and immune activation subsets stratified by gender and age (P>0.05). Meanwhile, neither serum HIV viral load nor serum CMV viral load was correlated with HLA-DR(+)CD(8)(+)/CD(8)(+), CD(8)(+)CD(38)(+)/CD(8)(+), CD(4)(+)T cell counts, and CD(4)(+)/CD(8)(+) ratio in the CMV and HIV/AIDS co-infection group (all P>0.05), while HIV viral load in HIV/AIDS only group was significantly correlated with HLA-DR(+)CD(8)(+)T/CD(8)(+), CD(38)(+)CD(8)(+)/CD(8)(+), CD(4)(+) T cell counts, CD(4)(+)/CD(8)(+) ratio (r=0.473, 0.575, -0.767 and -0.678, respectively, all P<0.05). Conclusions: CMV infections develop in HIV patients with advanced stage. CMV infection can cause life-threatening multiple organ lesions, especially in those with CD(4)(+) T cells less than 100 cells/μl. It is of great importance to screen CMV-IgM, pp65 antigen, CMV DNA to make early diagnosis and treatment.

Abstract
OBJECTIVE To explore the influential factors of kidney transplant patients' self-management, especially psychosocial variables. STUDY DESIGN This was a cross-sectional study. METHODS Questionnaires were administered to patients with the assistance of our team members to gather sociodemographic information, medical characteristics, self-management, social support, depression, and flourishing. RESULTS The study included 483 patients, 64.4% of whom were male. The score index of the total self-management scale was 81.95% and the "social psychology" dimension had the lowest index, at 75.63%. Higher scores for flourishing, shorter length of post-renal transplantation, more social support, lower body mass index, being female, and being employed were proved to be determinants of better self-management, and flourishing was identified as having the greatest influence. Some other indicators were also related to patients' self-management, particularly age, residence, income, hypertension, renal function, and depression. CONCLUSION The overall self-management of KT patients was middling, and the status of psychology management was not optimistic. This emphasized the importance of psychological intervention. For further exploration, flourishing was identified as contributing to better self-management, which implied that strengthening this factor could be another method of improving self-management, except that involves enhancing of social support and reducing depression. Age was also found to have differing degrees of influence on KT patients' self-management, which implies that younger patients should receive more support in self-management.

Abstract
Objective: To observe the cellular damage of low-dose combined exposure to Hg, Pb and Cd on hippocampal neurons in rat. Methods: SH-SY5Y cells were randomly divided into 8 groups by 2×2×2 factorial design: control group, Pb exposure group, Hg exposure group, Pb+Hg exposure group, Pb+Cd exposure group, Hg+Cd exposure group and Pb+Cd+Hg exposure group. And the cell viabilities were measured. On this basis, an animal model was established. Twenty eight-week-old SD pregnant rats were randomly divided into four groups by random number table, and five in each group: the control group(distilled water), 1-fold metal mixture exposure group (1×MM, poisoning solution containing mercury chloride 0.15 mg/L, lead acetate trihydrate 25 mg/L, cadmium chloride 7.5 mg/L), 5-fold metal mixture exposure group (5×MM, poisoning solution containing mercury chloride 0.75 mg/L, lead acetate trihydrate 125.00 mg/L, cadmium chloride 37.50 mg/L), 10-fold metal mixture exposure group (10×MM, poisoning solution containing mercury chloride 1.50 mg/L, lead acetate trihydrate 250.00 mg/L, cadmium chloride 75.00 mg/L). Pregnant rats drank water until delivery. Twenty male pups were selected and exposed to these metals through breast milk until weaned. The heavy metals dose of poisoning water was adjusted, and then the weaned rats were exposed to heavy metals via drinking poisoning water until adulthood (postnatal day 83). The blood samples and brain hippocampus samples were collected to observe the ultrastructural changes of hippocampus, and to determine the levels of Hg, Pb and Cd in blood. In addition, apoptosis rate and fluorescence intensity of reactive oxygen species and intracellular free calcium concentration ([Ca(2+)](i)) in hippocampal neurons were measured. Results: Cellular factorial design analysis showed that Hg+Pb+Cd (at no observed adverse effect level, 1.0, 0.5 and 0.1 μmol/L, respectively)had a interaction on cell viability after 48 or 72 hours of combined exposure (P<0.05). The results of ultrastructure showed that mitochondria decreased, ridges and matrixes gradually dissolved in rat hippocampal neurons of 5×MM group; nuclear chromatin aggregated, more ridges and matrixes dissolved and the mitochondria also decreased in rat hippocampal neurons of 10×MM group. The concentration of Hg, Pb and Cd in the blood of 1×MM group, 5×MM group and 10×MM group were higher than those in the control group, and the differences were statistically significant (P<0.001). There was no significant difference in apoptosis rate between the 1×MM group and the control group. The apoptosis rate of 5×MM group and 10×MM group was higher than that in the control group, and the differences were statistically significant (P<0.001). There was no statistically significant difference in the fluorescence intensity of reactive oxygen species in hippocampal neurons of the 1×MM group and the control group. The fluorescence intensity of reactive oxygen species in the 5×MM group and the 10×MM group was higher than that in the control group, the difference was statistically significant (P<0.05). There was no significant difference in the fluorescence intensity of [Ca(2+)](i) between the 1×MM group and the control group. The fluorescence intensity values of [Ca(2+)](i) in the 5×MM group and the 10×MM group were higher than the control group, the differences were statistically significant (P<0.001). Conclusion: Low-level combined exposure to Hg, Pb, and Cd caused synergistic neurotoxic damage, and the process may be related to the changes of neuronal apoptosis, reactive oxide species, and [Ca(2+)](i) levels.

Abstract
BACKGROUND The prevalence of Candida infections in paediatric intensive care units (PICUs) has dramatically increased as a result of resistance to conventional anti-fungal treatments. Because vitamin D has been shown to exhibit fungicidal activity against Candida infection in an in vitro antimicrobial screening, we aimed to investigate the effect of vitamin D on Candida infections in the PICU. METHODS Four hundred sixteen eligible children aged between 12 months to 5 years old admitted to the PICU, who were on broad-spectrum antibiotic therapy, participated in the study. Patients were randomly assigned to two study groups, receiving a plain yogurt drink (placebo group) or supplemented with 300 IU day-1 vitamin D (VD group). Primary outcome was defined as the incidences of Candida colonisation (Candida isolated from rectal swab) 14 days after enrollment. Secondary outcome measures were Candida growth in blood (candidaemia) and urine (candiduria). RESULTS The prevalence of candiduria as well as candidaemia was significantly lower in the VD-treated group (26 cases) than in the placebo group (62 cases). The mean (SD) length of PICU stay was obviously lowered in the VD group [11.8 (1.2) days] compared to the placebo group [15.2 (2.3 days)], whereas cases of patient death were similar between the two groups. CONCLUSIONS Supplementation of vitamin D effectively reduces infections of Candida in children who were critically ill and on broad-spectrum antibiotic treatment.

Abstract
BACKGROUND To investigate neonatal maternal separation (NMS) effects on airway inflammation of asthma and potential mechanism using a mouse model. METHODS 80 Balb/c neonatal male mice were randomly assigned to NMS and non-NMS groups. Feces were collected on PND21, 28, 35 and 42 to analyze microbiota and short-chain fatty acids (SCFAs). Non-NMS group were then divided into control (group A) and asthma groups (group B), while NMS group was assigned to NMS+asthma (group C) and NMS+SCFAs+asthma groups (group D). Inflammatory cells and eosinophils (EOS) in bronchoalveolar lavage fluid (BALF) were assessed. Pathological changes and cytokines in lung tissue were observed. Protein expression of Occludin and E-cadherin in airway epithelial was examined. RESULTS The number of S', diversity index H' and dominance index D', as well as content butyric acid in NMS group C were significantly lower than non-NMS group B (p<0.05). Mice in group C had a higher level of inflammatory cells and EOS compared with group A, B and D. EOS moderate infiltration was found in mice of group B, C and D. Mice in group C had significantly higher levels of cytokines and showed slightly increased bronchial epithelium goblet cells and a small amount of visceral secretions. Occludin and E-cadherin expression in lung in B, C and D groups was depressed, and protein level in group C was significantly lower than group B and D. CONCLUSIONS NMS is associated with exacerbated inflammation of adult asthma by changing intestinal microflora resulting in butanoic acid decline and airway epithelial barrier damage.

Abstract
Objective: To study the distribution of sub-health and occupational stress as well as their correlation among middle school teachers in Tianjin, then provide evidences for prevention and control of the status of sub-health. Methods: A total of 3 522 middle school teachers from six districts of Tianjin were recruited with stratified cluster sampling strategy for the investigation of Sub-Health Measurement Scale version 1.0 (SHMS V1.0) and Occupational Stress Inventory-Revised Edition (OSI-R) . Results: Detection rate of sub-health status among Tianjin middle school teachers was 58.55%. Men had significantly lower sub-health detection rate (55.19%) than women (59.71%) . Sub-health detection rate increased with age (P<0.05) , the sub-health detection rate among middle school teachers more than 50 years old was the highest (66.84%) . The mean score of OSI-R was 403.18±41.80 with the scores of 176.00±21.05, 103.17±17.53, and 124.02±20.28 for ORQ, PSQ, PRQ, respectively, which showed significantly difference compared with the occupational stress norm of China (P<0.001) . The mean scores of OSI-R, ORQ, PSQ, PRQ in different health status were significantly different (P<0.001) . The partial correlation analysis between the scores of sub-health and occupational stress of middle school teachers showed that the scores of occupational role and personal strain were negatively correlated with the scores of sub-health state (P< 0.001) , while, there was significantly positive correlation between the scores of personal resource and the scores of sub-health state (P<0.001) . Conclusion: Sub-health detection rate of middle school teachers in Tianjin is higher. Effective measures should be taken to appropriately mitigate the occupational stress level of middle school teachers, increase personal resources, and scientific and effective health guidance and education should be strengthened.

Abstract
Objective:To study the effects of stromal interaction molecule 1 (STIM1) RNA interference on cell proliferation, apoptosis, invasion and migration ability in vitro in human laryngeal cancer cells Hep-2. Method:Lentivirus transfection was used to realize the STIM1 RNA interference in human laryngeal cancer cells Hep-2. STIM1 RNA interference was verified by real-time PCR and western blotting. The cell proliferation was analyzed by CCK-8 method, Transwell chamber and wound scratch assay were used to detect cell invasion and migration ability, respectively. The cell apoptosis rate was evaluated by flow cytometry. The apoptotic proteins expression levels of caspase-3, Bax, Bcl-2, VEGF and MMP9 were detected by western blotting. Result:The gene expression levels of STIM1 mRNA and protein in human laryngeal cancer cells Hep-2 were significantly decreased after interference lentivirus transfection. After the interference of STIM1, the cell proliferation, invasion and migratory ability of Hep-2 cells in vitro declined (P<0.05). The cell apoptosis rate significantly increased after STIM1 RNA interference, along with the caspase-3 and Bax protein expression levels up-regulation, and the Bcl-2 expression levels down-regulation. The decrease of cell invasion and migratory ability was related with the down-regulation of VEGF and MMP9 protein expression. Conclusion:RNA interference of STIM1 in human laryngeal cancer cells Hep-2 inhibits the cell proliferation, invasion and migration ability in vitro, and enhances the cell apoptosis rate of Hep-2 cells.
