Abstract
Citrus is an important and widely cultivated fruit crop in South China. Although the species of fungal diseases of leaves and fruits have been extensively studied, the causal organisms of branch diseases remain poorly known in China. Species of Botryosphaeriaceae are known as important fungal pathogens causing branch diseases on citrus in the USA and Europe. To determine the diversity of Botryosphaeriaceae species associated with citrus branch diseases in China, surveys were conducted in the major citrus-producing areas from 2017 to 2020. Diseased tissues were collected from twigs, branches and trunks with a range of symptoms including cankers, cracking, dieback and gummosis. Based on morphological characteristics and phylogenetic comparison of the DNA sequences of the internal transcribed spacer region (ITS), the translation elongation factor 1-alpha gene (tef1), the β-tubulin gene (tub2) and the DNA-directed RNA polymerase II second largest subunit (rpb2), 111 isolates from nine provinces were identified as 18 species of Botryosphaeriaceae, including Botryosphaeria dothidea, B. fabicerciana, Diplodia seriata, Dothiorella alpina, Do. plurivora, Lasiodiplodia citricola, L. iraniensis, L. microconidia, L. pseudotheobromae, L. theobromae, Neodeightonia subglobosa, Neofusicoccum parvum, and six previously undescribed species, namely Do. citrimurcotticola, L. guilinensis, L. huangyanensis, L. linhaiensis, L. ponkanicola and Sphaeropsis linhaiensis spp. nov. Botryosphaeria dothidea (28.8 %) was the most abundant species, followed by L. pseudotheobromae (23.4 %), which was the most widely distributed species on citrus, occurring in six of the nine provinces sampled. Pathogenicity tests indicated that all 18 species of Botryosphaeriaceae obtained from diseased citrus tissues in this study were pathogenic to the tested Citrus reticulata shoots in vitro, while not all species are pathogenic to the tested Cocktail grapefruit (C. paradisi × C. reticulata) shoots in vivo. In addition, Lasiodiplodia was the most aggressive genus both in vitro and in vivo. This is the first study to identify Botryosphaeriaceae species related to citrus branch diseases in China and the results provide a theoretical basis for the implementation of prevention and control measures.

Abstract
OBJECTIVE To increase the awareness of malaria prevention and control among people going abroad and returners, so as to prevent the local retransmission of oversea imported malaria. METHODS Health education interventions for malaria control were given to people going abroad and returners in communities, and the changes of malaria prevention and control knowledge and medical-seeking behaviors were observed among the target populations. RESULTS There were 367 people going abroad and oversea returners from malaria-endemic areas in Zhangjiagang City from July 2018 to December 2019, and 18 imported malaria cases were found. Following the implementation of community health education, the awareness of malaria prevention and control knowledge increased significantly from 35.09% to 93.08% among the target populations (χ2 = 78.130, P < 0.01), and the proportions of carrying anti-malarial drugs and administration of anti-malarial drugs for emergency treatment increased from 12.14% and 11.46% to 26.79% and 26.79% (χ2 = 8.793 and 9.834, P < 0.05), respectively. In addition, the mean duration from malaria onset to the definitive diagnosis reduced from (5.86 ± 4.45) days to (3.11 ± 1.28) days (U = 64.000, P < 0.05). CONCLUSIONS Community health education based on the precision community administration is an effective approach for malaria control in current era.

Abstract
Almonertinib, a new third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, is highly selective to EGFR T790M-mutant non-small cell lung cancer (NSCLC). However, there is no available information on the form and molecular mechanism of Almonertinib-induced death in NSCLC cells. Herein, CCK-8 and colony formation assays, flow cytometry, electron microscopy, and western blots assay showed that Almonertinib inhibited NSCLC cells growth and proliferation by inducing apoptosis and autophagy which can be inhibited by a broad spectrum of caspase inhibitor Z-VAD-fmk or autophagy inhibitor chloroquine. Importantly, Almonertinib-induced autophagy was cytoprotective in NSCLC cells, and the blockade of autophagy improved cell apoptosis. In addition, Almonertinib increased reactive oxygen species (ROS) generation and clearance of ROS through pretreatment with N-acetyl-L-cysteine (NAC) inhibited the decrease of cell viability, apoptosis and increase of LC3-II induced by Almonertinib. The results of Western blot showed that both EGFR activity and downstream signaling pathways were inhibited by Almonertinib. Taken together, these findings indicated that Almonertinib induced apoptosis and autophagy by promoting ROS production in NSCLC cells.

Abstract
To investigate the predictive value of [18F]fluorodeoxyglucose-positron emission computed tomography(PET)/CT for disease progression in patients with dermatomyositis (DM) and interstitial lung diseases (ILD). Sixty-seven DM patients who underwent [18F] FDG-PET/CT imaging were retrospectively analyzed from January 2012 to September 2017 at PLA General Hospital. Their clinical manifestations and imaging characteristics were recorded. Compared with those chronically progressed (C-ILD), patients with rapid progression (RP-ILD) had significantly higher erythrocyte sedimentation rate (ESR) and standardized uptake value (SUV) in lungs (P<0.05). In patients with RP-ILD, SUV in lungs was positively correlated with age, disease course, and ESR. Receiver operating characteristic curve analysis suggested that when lung SUV cut off value was 2.25, the sensitivity and specificity to predict disease progression was 77.8% and 72.8%, respectively. Old age, longer disease course, low creatine kinase level, higher ESR, and high SUV are prognostic factors for DM-associated ILD.

Abstract
Background:Secukinumab (SEC) has demonstrated significant efficacy in patients (pts) with ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA).1-5 However, evidence regarding the efficacy of SEC across the axSpA disease spectrum is limited.Objectives:To assess the efficacy of SEC on key efficacy endpoints in pts with axSpA (nr-axSpA and AS) over 52 weeks from 6 pooled phase 3 clinical trials.Methods:This post hoc analysis included pooled data from tumour necrosis factor inhibitors (TNFi)-naïve pts in the MEASURE 1-5 (AS) and PREVENT (nr-axSpA) phase 3 trials. Assessments included proportion of patients achieving ASAS40, ASAS 5/6, ASAS partial remission (ASAS-PR), ASDAS-CRP major improvement, ASDAS-CRP inactive disease (ASDAS-CRP ID), BASDAI50 and mean change from baseline in nocturnal back pain and morning stiffness with any SEC 150 mg or SEC 300 mg or placebo (PBO) at Week 16, and sustainability was measured in pts treated with SEC at Week 52. Data are reported as non-responder imputation.Results:A total of 1558 TNFi-naïve pts (SEC 150 mg, N=932; SEC 300 mg, N=57 and PBO, N=569) with a mean age of 39.3 ± 11.58 years were included in the study. At Week 16, significantly higher improvements in pts treated with SEC versus PBO were observed in all efficacy endpoints (Table 1) with improvements sustained up to Week 52.Conclusion:SEC 300 mg and 150 mg provided significant and sustained improvement in the signs and symptoms of TNFi-naïve pts with axSpA regardless of radiographic status.References:[1]Baeten D, et al.

Abstract
Background:Biological DMARDs have widely used in the treatment of AS in last two decades, but NSAIDs still serves as a cornerstone in the treatment. Given the wide use of Acemetacin in AS and relative lack of clinical evidence on the selection of NSAIDs in the treatment of AS, the investigation on acemetacin treating AS is of great significance.Objectives:Our study aims to investigate efficacy and safety of acemetacin in the treatment of AS.Methods:Data on efficacy and safety is available in 1215 patients from the Chinese Ankylosing Spondylitis Imaging Cohort (CASPIC), which is collected through the Smart-phone SpondyloArthritis Management System (SpAMS)[1]. Patients’ self-assessments are completed online at baseline and every subsequent clinic visit. Physician-reported assessments, laboratory tests, and treatments were recorded by rheumatologists at every clinic visit.Results:1215 patients with AS were registered, of whom 992 were treated with acemetacin and 123 were treated with other NSAIDs. The results showed that total back pain and BASFI were significantly improved after three-month treatment of acemetacin, while comparing to other NSAIDs (P=0.027 and 0.015, respectively). After six-month treatment, patients taking acemetacin showed greater improvement in PGA (P=0.013), total back pain (P=0.049), night back pain (P=0.047), BASFI (P=0.042), ASDAS (P=0.007) and CRP (P=0.032) compared to those taking other NSAIDs. During the follow-up periods, no serious adverse events were reported. Mild abnormal liver function occurred in nine patients (9/992) treated with acemetacin and in six patients treated with other NSAIDs (6/123). See Table 1 for details.Conclusion:Acemetacin showed better efficacy and acceptable safety profile in the treatment of active ankylosing spondylitis comparing with other NSAIDs.References:[1]Ji, X., et al., Improvement of Disease Management and Cost Effectiveness in Chinese Patients with Ankylosing Spondylitis Using a Smart-Phone Management System: A Prospective Cohort Study.

Abstract
Background:The expression and experience of sexuality is a key part of an individual self-identity1, so it is essential for both healthy individuals and patients. Patients with ankylosing spondylitis (AS) may be susceptible to sexual issues due to disease activity, dysfunction and comorbid emotional problems. However, sexuality, especially sexual experience, are rarely paid attention in patients with AS.Objectives:Our study aims to assess sexual experience in male patients with AS, and analyze the factors affecting sexual experience.Methods:This is a cross-sectional study. A total of 113 patients with AS and 46 healthy people were investigated, matched according to age and body mass index. The Sexual Experience Questionnaire is used to assess male sexual experience. Linear regression analysis is used to explore the contributions of clinical variables to worse sexual experience.Results:There is a significant difference in the total sexual experience score between AS patients and healthy controls (41.92±8.83 vs 46.98±8.10, P=0.0013). Also, patients with AS have a worse score in all dimensions of sexual experience, including erectile function, individual satisfaction and couple satisfaction, comparing to healthy people. In the regression model after controlling for the effects of age, disease duration and body mass index, disease activity (BASDAI), function (BASFI), mobility (BASMI, chest expansion and finger-floor distance), health index (ASAS HI), sleep quality (PSQI) and psychological status (HADS, HADS-A and HADS-D) are significant determinants of sexual experience, including erectile function (except for chest expansion), individual satisfaction (except for BASMI) and couple satisfaction (except for BASMI). See Table 1 for details.Table 1.Multivariable regression analysis of association between sexual experience and clinical outcomesIndependentSexual experience total scoreErectile functionIndividual satisfactionCouple satisfactionβ (95%CI)Pβ (95%CI)Pβ (95%CI)Pβ (95%CI)PPain total-0.09 (-0.25, 0.07)0.28-0.27 (-0.58, 0.03)0.073-0.51 (-0.91, -0.100.014-0.15 (-0.32, 0.02)0.077BASDAI1.35 (-2.24, -0.45)0.003-0.42 (-0.75, -0.09)0.014-0.72 (-1.16, -0.28)0.001-0.21 (-0.40, -0.02)0.028BASFI-1.80 (-2.59, -1.01)<0.001-0.62 (-0.91, -0.32)<0.001-0.89 (-1.28, -0.50)<0.001-0.30 (-0.47, -0.13)0.001BASMI-1.04 (-2.01, -0.07)0.036-0.47 (-0.82, -0.12)0.008-0.48 (-0.96, 0.001)0.051-0.09 (-0.29, 0.12)0.413Chest expansion1.60 (0.24, 2.96)0.0210.50 (-0.004, 0.99)0.0520.74 (0.07, 1.42)0.0320.36 (0.08, 0.64)0.011Finger-floor distance-0.20 (-0.33, -0.07)0.003-0.07 (-0.11, -0.02)0.009-0.10 (-0.17, -0.03)0.003-0.04 (-0.06, -0.01)0.011ASAS HI-1.27 (-1.64, -0.91)<0.001-0.42 (-0.55, -0.28)<0.001-0.62 (-0.80, -0.43)<0.001-0.24 (-0.32, -0.16)<0.001PSQI-0.60 (-1.11, -0.09)0.021-0.19 (-0.38, -0.004)0.045-0.28 (-0.54, -0.03)0.03-0.13 (-0.23, -0.02)0.019HADS-0.53 (-0.76, -0.29)<0.001-0.18 (-0.27, -0.09)<0.001-0.24 (-0.36, -0.13)<0.001-0.10 (-0.15, -0.05)<0.001HADS-A-0.86 (-1.30, -0.42)<0.001-0.28 (-0.44, -0.12)0.001-0.42 (-0.63, -0.20)<0.001-0.17 (-0.26, -0.07)<0.001HADS-D-0.99 (-1.45, -0.53)<0.001-0.35 (-0.52, -0.19)<0.001-0.44 (-0.67, -0.21)<0.001-0.20 (-0.29, -0.10)<0.001Conclusion:Worse sexual experience is associated with increased disease activity, decreased function, poor mobility, decreased health index, poor sleep quality and psychological status. Therefore, special attention to worse sexual experience in patients with AS is essential to assess disease-related suffering and develop new patient management strategies.References:[1]Hill J, Bird H, Thorpe R.

Abstract
BACKGROUND The coronavirus disease (COVID-19) pandemic has affected healthcare workers (HCWs) in their clinical practice. HCWs were challenged with new guidelines and practices to protect themselves from occupational risks. AIM To determine whether hand hygiene behaviour by real-time measurement was related to the dynamic of the epidemic, and the type of patient being cared for in France. METHODS This study used an automated hand hygiene recording system to measure HCW hand hygiene on entry to and exit from patient rooms throughout the COVID-19 pandemic. The correlation between hand hygiene compliance and COVID-19 epidemiological data was analysed. Analysis of variance was performed to compare compliance rate during the different periods of the epidemic. FINDINGS HCW hand hygiene rate on room entry decreased over time; on room exit, it increased by 13.73% during the first wave of COVID-19, decreased by 9.87% during the post-lockdown period, then rebounded by 2.82% during the second wave of the epidemic. Hand hygiene during patient care and hand hygiene on room exit had a positive relationship with the local COVID-19 epidemic; conversely, hand hygiene on room entry did not depend on the trend of the epidemic, nor on nursing of COVID-19 patients, and it decreased over time. CONCLUSION HCWs modified their behaviours to face the risk propensity of the pandemic. However, to improve the poor compliance at room entry, reducing confusion between the hand hygiene recommendation and glove recommendation may be necessary; disinfection of gloving hands might solve this issue.

Abstract
SETTING: China National Tuberculosis Programme, 2010-2017.OBJECTIVE: To describe the epidemiology of childhood (age < 15 years) TB, including treatment outcomes and risk factors for unfavourable outcomes and death.DESIGN: We used a cross-sectional design for the descriptive component and a cohort design for treatment outcomes and their risk factors (assessed using log binomial regression).RESULTS: Of 40 561 children, 77.7% (n = 31 529) were aged 10-14 years and 19.6% (n = 7931) were bacteriologically confirmed. Around 14% (n = 5827) belonged to migrant families (internal migration) and 4.0% (n = 1,642) were actively detected. Over 8 years, annual notification was consistently very low (<1%), and notification of bacteriologically confirmed TB decreased by half. Unfavourable outcomes were seen in 6% and deaths in 0.4%; there were no significant changes over the years. The independent predictors of unfavourable outcomes were active case finding and extrapulmonary TB. Children belonging to migrant family were more likely to die. Independent predictors of unfavourable outcomes as well as death were age < 5 years and previous treatment.CONCLUSION: China needs to address the issue of under-detection of childhood TB, especially in younger age groups. The risk factors identified require attention if China is to attain zero child TB deaths.

Abstract
Background: BAY 1862864 is an α-particle emitting thorium-227-labeled CD22-targeting antibody. This first-in-human dose-escalation phase I study evaluated BAY 1862864 in patients with CD22-positive relapsed/refractory B cell non-Hodgkin lymphoma (R/R-NHL). Materials and Methods: BAY 1862864 intravenous injections were administered at the starting thorium-227 radioactivity dose of 1.5 MBq (2 or 10 mg antibody), and the radioactivity dose escalated in ∼1.5 MBq increments (10 mg antibody) until the maximum tolerated dose (MTD) was reported. The primary objective was to determine the safety, tolerability, and MTD. Results: Twenty-one patients received BAY 1862864. Two dose-limiting toxicities (grade 3 febrile neutropenia and grade 4 thrombocytopenia) were reported in one patient in the 4.6 MBq (10 mg antibody) cohort. The MTD was not reached. Ten (48%) patients reported grade ≥3 treatment-emergent adverse events, with the most common being neutropenia, thrombocytopenia, and leukopenia, each occurring in 3 (14%) patients. Pharmacokinetics demonstrated the dose proportionality and stability of BAY 1862864 in the blood. The objective response rate (ORR) was 25% (5/21 patients) according to the LUGANO 2014 criteria, including 1 complete and 4 partial responses. The ORR was 11% (1/9) and 30% (3/10) in patients with relapsed high- and low-grade lymphomas, respectively. Conclusions: BAY 1862864 was safe and tolerated in patients with R/R-NHL. The Clinical Trial Registration numbers: NCT02581878 and EudraCT 2014-004140-36.

Abstract
Objective: To investigate the role of artificial intelligence-based coronary CT blood flow reserve score (FFRCT) in assessing hemodynamic relevance in patients with deep myocardial bridge (MB) of the left anterior descending coronary artery. Methods: A total of 113 patients diagnosed with deep MB of the left anterior descending coronary artery by coronary CT angiography (CCTA) at the Department of Radiology of Tongji Hospital Affiliated to Tongji University from January 2017 to December 2019 were retrospectively analyzed. The location, length, depth, and degree of systolic compression of the MB were measured. The artificial intelligence-based coronary FFRCT software was employed to calculate the FFRCT value of the deep MB of the left anterior descending coronary artery. With the boundary of 0.80, all patients were divided into FFRCT normal group (FFRCT>0.80) and FFRCT abnormal group (FFRCT≤0.80), and the relationship between FFRCT abnormality and the location, length, depth, and degree of systolic stenosis of the deep MB of the left anterior descending branch was analyzed. The effectiveness of the receiver operating characteristic (ROC) curve in predicting FFRCT abnormalities was measured by using ROC curve to analyze the length, depth, and degree of systolic stenosis of MB. Results: There were no significant differences in age, gender and high-risk factors between FFRCT normal group (n=79) and FFRCT abnormal group (n=34) (P>0.05). In terms of clinical symptoms, unstable angina, asymptomatic myocardial ischemia, stable angina in the FFRCT normal group were 15.2%, 41.8%, 32.9%,respectively, while 32.4%, 23.5%, 35.3% in the FFRCT abnormal group,respectively. Except for unstable angina (χ²=4.32,P=0.038), there were no significant differences in asymptomatic myocardial ischemia and stable angina between the two groups (χ²=3.42, 0.06, P>0.05). The length of deep MB was about (36±5) mm in the FFRCT normal group and (44±5) mm in the FFRCT abnormal group, respectively. The difference between the two groups was statistically significant (t=-7.703, P<0.001). The ROC curve showed that the optimal critical value of the length of the deep MB was 39.7 mm, the area under the curve was 0.88 (95%CI:0.81-0.95, P<0.001), and the accuracy rate of diagnosing FFRCT ≤0.80 was 82.3%. Conclusion: FFRCT value is of great value in the evaluation of hemodynamics in patients with deep myocardial bridge of left anterior descending coronary artery, and the length of deep myocardial bridge is an important factor affecting FFRCT value.

Abstract
AIMS Metagenomic next-generation sequencing (mNGS) has been utilized for diagnosing infectious diseases. It is a culture-free and hypothesis-free nucleic acid test for diagnosing all pathogens with known genomic sequences, including bacteria, fungi, viruses and parasites. While this technique greatly expands the clinical capacity of pathogen detection, it is a second-line choice due to lengthy procedures and microbial contaminations introduced from wet-lab processes. As a result, we aimed to reduce the hands-on time and exogenous contaminations in mNGS. METHODS AND RESULTS We developed a device (NGSmaster) that automates the wet-lab workflow, including nucleic acid extraction, PCR-free library preparation and purification. It shortens the sample-to-results time to 16 and 18·5 h for DNA and RNA sequencing respectively. We used it to test cultured bacteria for validation of the workflow and bioinformatic pipeline. We also compared PCR-free with PCR-based library prep and discovered no differences in microbial reads. Moreover we analysed results by automation and manual testing and found that automation can significantly reduce microbial contaminations. Finally, we tested artificial and clinical samples and showed mNGS results were concordant with traditional culture. CONCLUSION NGSmaster can fulfil the microbiological diagnostic needs in a variety of sample types. SIGNIFICANCE AND IMPACT OF THE STUDY This study opens up an opportunity of performing in-house mNGS to reduce turnaround time and workload, instead of transferring potentially contagious specimen to a third-party laboratory.

Abstract
During the last decade there has been a craze for the percutaneous edge-to-edge mitral valve repair technique with the Mitra-Clip device. This is an alternative treatment to mitral valve surgery for severe mitral regurgitation. In France, this device is aimed at poor candidates for mitral valve surgery. It involves intra-cardiac prosthetic material, which exposes them to the risk of bacterial endocarditis. The consequences of this infective disease can be dramatic, especially for these old patients who suffer from multiple comorbidities. It appears to be a rare but relatively unknown and potentially underestimated complication. The relative data remain scarce and consist of rare case-reports. We report an original case of a Methicilline-sensitive Staphylococcus epidermidis mitral endocarditis following the implantation of clips two months earlier. The patient was then successfully treated with antibiotics. Since the first Mitra-Clip implantation in 2003, only 19 cases of endocarditis have previously been reported. This article proposes a review of theses case-reports and a collection of their relevant clinical, echocardiographic and microbiological characteristics, the delivered therapies and their outcomes. These data contribute to a humble discussion around the main stakes of the disease, which are the prevention, the diagnosis, the involved bacteria's type, the prognosis and the treatments with a focus on the question of the recourse to surgical management.

Abstract
The results of a 3+1 sterile neutrino search using eight years of data from the IceCube Neutrino Observatory are presented. A total of 305 735 muon neutrino events are analyzed in reconstructed energy-zenith space to test for signatures of a matter-enhanced oscillation that would occur given a sterile neutrino state with a mass-squared differences between 0.01 and 100 eV^{2}. The best-fit point is found to be at sin^{2}(2θ_{24})=0.10 and Δm_{41}^{2}=4.5 eV^{2}, which is consistent with the no sterile neutrino hypothesis with a p value of 8.0%.
