Abstract
To explore screening tools for children with autism spectrum disorder (ASD), which are convenient for primary hospitals, it can provide basic data for formulating ASD prevention policies. This was a cross-sectional study by cluster sampling. Huyi District and Xincheng District were extracted for investigation in Xi'an City. From July 2021 to September 2022, all children aged from 3 months to 36 months who live in the two districts were subjected to primary screening. The child care physician used the routine screening tool "warning signs checklist for screening psychological, behavioral and developmental problems of children" and cartoon pictures of "early high-risk warning signs of autism", the children who were positive in the initial screening were referred to the district level maternal and child health hospital for re-screening, and those who were positive in the re-screening were referred to Xi 'an Children's Hospital for diagnosis. The results showed that a total of 17 905 children aged from 3 months to 36 months were initially screened in the two districts, including 10 588 children aged from 18 months to 36 months, 50 children who were positive in the initial screening and 50 children who were re-screened. 23 children (18 boys and 5 girls) were diagnosed with ASD. The prevalence rate of ASD in children was 2.17‰ (95% confidence interval:1.29‰-3.06‰). 42 children were positive for "warning signs checklist" at the preliminary screening, and 19 were confirmed as ASD. 27 children were positive for "cartoon pictures" in the preliminary screening, and 23 were confirmed with ASD. The "cartoon pictures" in the preliminary screening and diagnosis of consistent rate was higher than the "warning signs checklist", two kinds of screening methods comparison were statistically significant difference in the odds of consistent (χ2=11.01, P=0.001). In conclusion, relying on the three-level network of maternal and child health care, it is conducive to the whole process management of screening and diagnosis of children with ASD, and to guide the formulation of prevention policies. The cartoon pictures of "early high-risk warning signs of autism" can assist the identification of children with ASD based on the "warning signs checklist", which is simple, effective and suitable for promotion in the community health care.

Abstract
Glutaredoxin (GRX) is a class of small redox proteins widely involved in cellular redox homeostasis and the regulation of various cellular processes. The role of GRX gene in the differentiation of Populus spp. is rarely reported. We compared the similarities and differences of GRX genes among four sections of poplar using bioinformatics, corrected the annotations of some GRX genes, and focused on analysing their transcript profiling and adaptive evolution in Populus spp. A total of 219 GRX genes were identified in four sections of poplar, among which annotations for 13 genes were corrected. Differences in GRX genes were found between sect. Turanga, represented by P. euphratica, and other poplar sections. Most notably, P. euphratica had the smallest number of duplication events for GRX genes (n = 9) and no tandem duplications, whereas there were >25 duplication events for all other poplars. Furthermore, we detected 18 pairs of GRX genes under positive selection pressure in various sections of poplar, and identified two groups of GRX genes in the Salicaceae that potentially underwent positive selection. Expression profiling results showed that the PtrGRX34 and its orthologous genes were upregulated under stress treatments. In summary, the GRX gene family underwent expansion during poplar differentiation, and some genes underwent rapid evolution during this process, which may be beneficial for Populus spp. to adapt to environmental changes. This study may provide more insights into the molecular mechanisms of Populus spp. adaptation to environmental changes and the adaptive evolution of GRX genes.

Abstract
PURPOSE/OBJECTIVE(S) Xerostomia, caused by radiation-induced parotid damage, is the most commonly reported complications of radiotherapy (RT) to nasopharyngeal carcinoma (NPC). This study aimed to evaluate the value of IVIM MR in monitoring radiation parotid gland damage and predicting the risk of xerostomia. MATERIALS/METHODS A total of 54 patients were enrolled and underwent IVIM MR scans at before RT, after the fifth fraction, halfway through the course of RT, and at the end of radiotherapy. The parameters of IVIM MR include pseudo-diffusion coefficient (D*), perfusion fraction (f), and pure diffusion coefficient (D). The degree of xerostomia in NPC patients was assessed before each MR examination using the acute radiation morbidity scoring criteria proposed by the Radiation Therapy Oncology Group (RTOG). Concurrently, the time when the patient first reported suffering from xerostomia was recorded. The IVIM parameters trend throughout the RT, and the relationships between IVIM parameters and xerostomia, were analyzed. RESULTS All of the IVIM parameters increased from pre-RT to post-RT significantly (all p < 0.001). The increase rate of D from pre-RT to halfway through the RT was 32.61%, which was significantly higher than 15.64% from halfway to post-RT (p<0.001), indicating that cell necrosis in the first half of treatment is significantly higher than that in the second half. Both D* and F had significantly increased from pre-RT to halfway through the radiotherapy (p<0.001), with an increase rate of 19.58% and 29.38%, respectively. However, no significant increase was observed from Halfway to post-RT (p>0.05), with an increase rate of 4.10% and 8.30%, respectively. This may be due to radiation-induced vasculitic dilation that is significant in the first half of the radiotherapy but plateaus in the second half. Pre-D (OR = 23.85; 95% CI = 2.39, 237.82; p = .007) and pre-D* (OR = 0.75; 95% CI = 0.63, 0.91; p = 0.003) are independent influencing factors for xerostomia at 3 months after the completion of RT. D and F were significantly higher after the fifth fraction compared with Pre-RT (both p<0.05), respectively increased 31.25% and 25.16%. D* increase by 15% (p = 0.081). IVIM scans can assess parotid gland damage early. And the average time of parotid damage underwent IVIM scan was 5.99 ± 0.84 (day), much earlier than 11.84 ± 2.74 (day) according to RTOG. CONCLUSION Our study indicates that IVIM MR can dynamically monitor radiotherapy-induced parotid gland damage, and much earlier and objectively than RTOG.

Abstract
The aim of this study was to evaluate the biomarker potential of TIMP-2 in septic-induced acute kidney injury (AKI). Healthy male rats (n=56, age 8-10 weeks, body weight 250-300 g) were randomized into 3 groups: controls (intact rats, n=6), sham-operated (SO, n=24), and sepsis model (cecum ligation and perforation, CLP, n=24). Thirty minutes before and 6, 12, 24, and 48 h after surgery, blood samples were collected to measure serum creatinine, blood urea nitrogen (BUN), and TIMP-2 and the kidneys were isolated for histopathological analysis and Western blotting. The key sepsis-related genes were screened through bioinformatics analysis. In 24 and 48 h after surgery, 2 rats in the SO group reached the diagnostic criteria of AKI (increased levels of serum creatinine and BUN). In the CLP group, serum creatinine in 6 h after the surgery was slightly higher than 30 min before the surgery, but this change did not meet the diagnostic criteria for AKI. In the CLP group, BUN was normal 6 h after the surgery, but increased after 12 h. In more than 50% rats of the CLP group, serum creatinine and BUN significantly increased 12 h after operation, so this can be diagnosed as AKI. In rats of the CLP group, plasma TIMP-2 was elevated 6 h after surgery and increased with time, suggesting that plasma TIMP-2 can be used as an early marker of AKI. Histological examination of the kidneys in this group revealed destruction of the renal tubular structure, swelling of renal tubular epithelium, the disappearance of brush edge and collapse of necrotic epithelial cells, etc., and the degree of damage increased with time. Immunohistochemistry showed that TIMP-2 was expressed in rats of the CLP group at all terms of the experiment. The expression of TIMP-2 and pyroptosis-related proteins (NLRP3, IL-1β, caspase-1, and GSDMD) in the CLP group was higher than in the SO group (p<0.05) and increased with time, suggesting that pyroptosis is involved in AKI. Thus, plasma TIMP-2 is sensitive indicator for the early detection of kidney injury and can be used as an early biomarker of AKI.

Abstract
OBJECTIVE Primary pulmonary lymphoepithelioma-like carcinoma (PPLELC) is a rare lung malignancy occurring most frequently in young non-smokers from Southeast Asia. Given its low incidence, PPLELC clinical features, treatment methods, and the factors affecting its prognosis remain elusive. To date, PPLELC data are mainly derived from clinical case reports, and no cohort studies are available. Therefore, we retrospectively analyzed a group of PPLELC cases and summarized the clinical features of patients, treatment responses, and the factors affecting patient prognosis. PATIENTS AND METHODS A total of 91 patients having primary pulmonary lymphoepithelioma-like carcinoma were recruited in this study. These included sex, age, place of birth, smoking history, pre-treatment symptoms, tumor location, tumor markers, maximum tumor diameter, treatment regimen, lymph node presence metastasis after an operation, pathological picture, immunohistochemistry, genetic findings, and tumor stage grading. We determined the overall survival (OS), progression-free survival (PFS), basic clinical characteristics, treatment option, treatment response, and recurrence pattern among the patients. In addition, we understood the influence of sex, age, tumor, nodes, and metastases (TNM) stage, tumor size, and surgery over patient prognosis. RESULTS Primary pulmonary lymphoepithelioma-like carcinoma is more common among young non-smokers, with a slightly higher incidence in women than in men. The expression of Epstein-Barr virus-encoded small RNA (EBER), pancytokeratin (PCK), Cytokeratin 5/6 (CK5/6), and tumor protein 63 (P63) was positive in immunohistochemistry. Serum cytokeratin 19 fragment antigen (CYFRA21-1) and Epstein-Barr DNA (EB-DNA) could be used as markers to diagnose primary pulmonary lymphoepithelioma-like carcinoma. TNM stage and surgery were independent prognostic factors. CONCLUSIONS Primary pulmonary lymphoepithelioma-like carcinoma is rare, showing a good prognosis.

Abstract
BackgroundRecent studies have pointed out that complement system activation is a major alteration in early atherosclerotic plaques, and complement C5 has promising value as a novel circulating biomarker of atherosclerosis, but the relationship between C5 and carotid atherosclerotic (CAS) plaque in rheumatoid arthritis (RA) is still unclear.ObjectivesTo investigate the clinical significance of serum complement C5 and the association with CAS plaque in patients with RA.Methods143 patients with RA were included in the study, and 46 cases with age- and sex- matched healthy physical examination without RA or CAS plaque served as a normal control. All RA patients were divided into RA with CAS plaque group and RA without CAS plaque group according to the presence or absence of plaque formation in the carotid artery. The subject’s demographic data, laboratory investigations and serum samples were collected. Body mass index (BMI) and Disease Activity Score 28-joint counts (DAS28) were calculated. Glucocorticoid and DMARDS use were recorded in the past 3 months. ELISA method was used to determine the concentration of complement C5 in the serum of each participation. CAS plaque was determined by color Doppler ultrasound.ResultsSerum complement C5 in RA group was significantly lower than that in control group (P<0.05), whereas C5 level in RA with CAS plaque group was significantly higher than that in RA without CAS plaque group (P<0.05). In RA group, serum C5 level was positively correlated with CAS plaque, high-sensitivity C-reactive protein (hs-CRP) and fibrinogen (FIB) (r=0.204, P=0.017; r=0.225, P=0.009; r=0.186, P=0.029;). In addition, there was no significant correlation between serum C5 and sex, age, BMI, course of disease, DAS28, lipid profile (TG, serum triglyceride; TC, total cholesterol; LDLC, low density lipoprotein cholesterol; HDLC, high density lipoprotein cholesterol; TC/HDLC; LDLC/HDLC), immune markers (RF, rheumatoid factor; anti-CCP, anti-cyclic citrullinated peptide antibodies), cytokine (IL-6, Interleukin-6; TNF-α, Tumor necrosis factor-α), erythrocyte sedimentation rate (ESR) (all P>0.05), or drug therapy (all P>0.05).ConclusionC5 may be a novel circulating marker of atherosclerosis in RA patients, it might promise to assist in risk stratification for cardiovascular disease in the future.References[1]Martínez-López D, et al.

Abstract
BackgroundDermatomyositis (DM) and polymyositis (PM) are rare heterogenous systemic autoimmune disorders of the skin, muscles, and other organs with few effective treatment options available. They are described as devastating diseases but the full impact on patients’ lives in Europe is not well understood.ObjectivesTo systematically review and summarize evidence on humanistic burden of disease in patients with DM and PM in Europe to better understand patient-relevant aspects of disease and key domains of life impacted by DM and PM in the European setting.MethodsA systematic literature review (SLR) was conducted in MEDLINE and Embase databases to identify studies in children and adults with DM and PM, published in the English language between Jan 1, 2011, and Apr 28, 2021. Only primary studies enrolling 10 or more patients were included, irrespective of country or region. Each eligible article was independently reviewed by two reviewers. The title and study abstracts were reviewed to assess eligibility for full-text review. The topics of interest were clinical, humanistic, and economic burden of disease, as well as current management and unmet needs in DM and PM. Information on geographic scope was extracted from the papers of included studies. The current abstract summarizes SLR results on humanistic burden of DM and PM in European patients.ResultsA total of 2,967 non-duplicated publications were retrieved from medical databases and analyzed against pre-defined study selection criteria. There were 2,574 records excluded at title and abstract screening. Remaining 393 records were analyzed in the full text with 208 papers considered relevant. Additional 21 papers were identified from searching reference list of relevant studies and conference proceedings. In total, 222 studies described in 229 publications were included in data abstraction. Among 43 studies conducted across 14 European countries, 12 studies evaluated health-related quality of life (HRQoL) and work productivity in patients with DM and PM. In 6 studies, patients received standard of care therapy. Six studies enrolled adults with DM and PM and 6 were conducted in patients with juvenile onset of DM. There were 6 cross-sectional analyses, 4 longitudinal cohort studies, 2 case-control studies, with sample size ranging from 11 to 246 patients. Adults with DM and PM had significantly worse HRQoL across multiple domains of 36-Item Short Form Survey (SF-36) compared to controls from general population, with a strong negative impact of muscle weakness on physical functioning. Patients reported high difficulties in performing leisure time activities, moving around and work as indicated by median scores of 4-5 points in a 7-point Myositis Activity Profile (MAP). Reduced grip force in DM and PM adults was significantly associated with worse performance in domestic activities in the MAP assessment (p<0.05). In women with DM and PM, poor grip force additionally impacted vitality and mental health as measured by SF-36 (p<0.05). There were no associations between grip force and any SF-36 domain in men. Approximately 60% of adult patients rated their ability to work as “poor” or “less good” according to the Work Ability Index, 68% of patients had more than one week of sick leave in the past year, and 20.8% of them were permanently not able to work for at least 2 years. Children and adolescents with DM had impaired physical and psychosocial functioning compared to healthy norms with 40% of individuals showing increased emotional distress requiring in-depth psychological assessment.ConclusionEuropean patients with DM and PM experience a muscle weakness that has a detrimental impact on HRQoL, daily activities and ability to work. Similar disease impact on HRQoL was reported in patients in North America. These findings suggest a need for a novel therapy that will restore physical functioning in patients with DM and PM.Disclosure of InterestsJens Schmidt Speakers bureau: Euroimmun, CSL Behring, Consultant of: Alnylam, Argenx, Biotest, CSL Behring, Kezar Life Sciences, LFB, Novartis, Octapharma, UCB, Grant/research support from: CSL Behring, Novartis, Konrad Pisarczyk Consultant of: Kezar Life Sciences, Richard Leff Shareholder of: Kezar Life Sciences, Consultant of: Kezar Life Sciences, Kiruthi Palaniswamy Shareholder of: Kezar Life Sciences, Employee of: Kezar Life Sciences, Eunmi Park Shareholder of: Kezar Life Sciences, Employee of: Kezar Life Sciences, Li Long Shareholder of: Kezar Life Sciences, Employee of: Kezar Life Sciences

Abstract
BackgroundDermatomyositis (DM) and polymyositis (PM) are rare heterogenous systemic autoimmune disorders of the skin, muscles and other organs that may have a devastating impact on patients’ lives. Despite various therapies used in clinical practice, a notable proportion of patients seem not to achieve sustainable remission. There is a need to better understand long-term outcomes and comorbidities in patients with DM/PM in Europe.ObjectivesTo systematically review and summarize evidence on clinical burden of disease in patients with DM/PM in Europe.MethodsA systematic literature review (SLR) was conducted in MEDLINE and Embase databases to identify studies in children and adults with DM/PM, published in the English language between 2011 and 2021.

Additional 21 papers were identified from searching reference list of relevant studies and conference proceedings. In total, 222 studies (229 publications) were included in data abstraction. Among 43 studies conducted across 14 European countries, 23 studies evaluated long-term outcomes of disease and burden of comorbidities. There were 14 longitudinal cohort studies, 7 cross-sectional analyses and 2 case-control studies. Only 29-44% of DM/PM adults achieved remission. Between 38% and 62% of adults with DM/PM required at least 3 different medications, suggesting inadequate response to initial and subsequent regimens. During a mean follow-up of 13.9 years, 69% patients with JDM had polycyclic or chronic disease characterized by periods of remission and recurrence or by permanently active disease for more than 2 years after diagnosis. A notable proportion of children (60.4%) showed evidence of damage in at least one body organ and 13-20% of patients had complications such as calcinosis, lipodystrophy, or muscle atrophy. Adults with DM/PM often suffered from interstitial lung disease (16-66%), serious infections leading to hospitalization or death (21-26.7%), and cardiovascular disorders (CVDs) (19-71%). Compared to age and gender matched controls without DM, patients with DM had 16-times higher risk of venous thromboembolism (HR=16.44, 95% CI: 7.54-35.86). Incidence of coronary heart disease, hemorrhagic stroke, or ischemic stroke during 10-year follow-up was approximately 1.5- to 2-times higher in DM/PM adults relative to general population. Multiple studies reported high rates of any malignancy in DM adults (7.5-33%) and in PM adults (8-11.7%). During approximately 24,000 patient-years of follow-up, adults with DM/PM had more than 4-times higher incidence of lung cancer compared to general population that also was one of the highest incidences among multiple other autoimmune diseases. Long-term prognosis in DM/PM was poor with 20-year survival below 70%. The most common causes of deaths were pulmonary-related, malignancies, and cardiac complications. Mortality due to lung cancer was more than 4-times higher than in general population (standardized mortality ratio=4.17, 95% CI: 3.03-5.60).ConclusionEuropean patients with DM/PM suffer from substantial burden of comorbidities including serious infections, malignancies and CVDs that lead to poor long-term outcomes. A notable proportion of adult and juvenile patients do not achieve sustainable remission or experience relapse indicating high unmet need.Disclosure of InterestsJiří Vencovský Speakers bureau: Abbvie, Biogen, Boehringer, Eli Lilly, Gilead, MSD, Novartis, Pfizer, Roche, Sanofi, UCB, Werfen, Consultant of: Abbvie, Argenx, Boehringer, Eli Lilly, Gilead, Octapharma, Pfizer, UCB, Grant/research support from: Abbvie, Konrad Pisarczyk Consultant of: Kezar Life Sciences, Richard Leff Shareholder of: Kezar Life Sciences, Consultant of: Kezar Life Sciences, Eunmi Park Shareholder of: Kezar Life Sciences, Employee of: Kezar Life Sciences, Kiruthi Palaniswamy Shareholder of: Kezar Life Sciences, Employee of: Kezar Life Sciences, Li Long Shareholder of: Kezar Life Sciences, Employee of: Kezar Life Sciences.

Abstract
Objective: To dynamically observe the clinical efficacy of entecavir and the changes of PD-1+CXCR5+CD4+T lymphocytes and sPD-1 levels in peripheral blood of HBeAg-positive chronic hepatitis B virus carriers treated with entecavir, and further explore its clinical significance. Methods: There were 31 cases of chronic hepatitis B virus carriers in the treatment group (A), 32 cases of chronic hepatitis B virus carriers in the treatment group (B), and 15 cases of chronic hepatitis B virus carriers in the non-treatment group (C).Three groups peripheral blood samples and clinical data at 0, 24 and 48 weeks were collected and compared. PD-1+CXCR5+CD4+T lymphocytes were detected by flow cytometry, and the level of sPD-1 was detected by enzyme-linked immunosorbent assay. ANOVA and Spearman correlation analysis were performed on the measurement data among the three groups. Results: At week 0, the serum levels of HBsAg, HBeAg and HBV DNA were significantly higher in groups A and C than group B. PD-1+CXCR5+CD4+T lymphocytes in peripheral blood were significantly higher in group B (4.70%±1.58%) than group A (3.25%±1.01%) and group C (2.77%±0.67%) (F=16.65, P<0.05). There was no significant difference between group A and group C (P>0.05). Peripheral blood sPD-1 in group B [(1 866.62±1 472.70) pg/ml] was significantly higher than group A [(824.86±538.66) pg/ml] and group C [(618.19±602.62) pg/ml] (F=10.95, P<0.05). There was no significant difference between group A and group C (P>0.05). At 48 weeks, the serum HBsAg did not decrease significantly in groups A and C than baseline (P>0.05), but were significantly higher than group B (P<0.05). Serum HBeAg levels were decreased significantly in groups A and B than baseline (P<0.05). <0.05), but group A was significantly higher than group B (P<0.05), and there was no significant difference between group A and group C (P>0.05). Serum HBV DNA level was significantly lower in groups A and B than group C (P<0.05), and there was no significant difference between group A and group B (P>0.05). Peripheral blood PD-1+CXCR5+CD4+T lymphocytes were significantly lower in Group A (1.56%±0.73%) and group B (1.32%±0.43%) than group C (2.64%±0.85%) (P<0.05). Peripheral blood sPD-1 were significantly lower in group A [(289.05±215.86) pg/ml] and group B [(236.01±173.92) pg/ml] than group C [(650.34±598.46) pg/ml] (P<0.05). There was no significant difference between group A and group B. Correlation analysis results: In group A at 48 weeks, the decreased level of PD-1+CXCR5+CD4+T lymphocyte ratio had no correlation with the decreased level of HBsAg and HBV DNA, but was positively correlated with the decreased level of HBeAg (r=0.376, P<0.05). The decreased level of sPD-1 had no correlation with the changes of HBsAg, but was positively correlated with the decreased levels of HBeAg and HBV DNA (r=0.598 and 0.384, P<0.05). In group B at 48 weeks, the decreased levels of PD-1+CXCR5+CD4+T lymphocytes and sPD-1 were positively correlated with the decreased levels of HBsAg, HBeAg, and HBV DNA (P<0.05). Conclusion: Hepatitis B virus replication and expressions in HBeAg-positive chronic hepatitis B virus carriers were significantly inhibited after 48 weeks of antiviral treatment, which is related not only to entecavir treatment, but also to the immunological mechanism involved in sPD-1. Moreover, the inhibition of HBeAg expression is associated with a decrease in the number and/or activity of PD-1+CXCR5+CD4+T lymphocytes.

Abstract
Abstract
A four-day-old neonate was referred to the Oral and Maxillofacial Surgery department by the Paediatric medical team regarding a cystic lesion associated with the child’s lingual frenulum. The lesion appeared to be affecting feeding causing a potential failure to thrive.
An MRI showed a 22 x 14 x 17 mm thin-walled oval cystic structure within the midline of the tongue/floor of the mouth. The decision was made with the family to surgically excise the lesion under a general anaesthetic. The histopathology results demonstrated the cyst to be lined with both gastric surface mucus cells and ciliated respiratory-type epithelium.
The patient was diagnosed with having an Oral Foregut Duplication Cyst (OFDC), also known as a lingual choristoma, enteric duplication cyst or heterotopic gastrointestinal cyst of the oral cavity. OFDCs are benign developmental anomalies that contain foregut derivatives. The cyst linings can contain gastrointestinal, respiratory, squamous or mixed cell types. There are only approximately 58 cases reported in the literature, demonstrating the rarity of these lesions.
OFDCs can be asymptomatic but in some neonates, they can present with difficulties feeding, swallowing and even has been shown to cause airway obstruction. If left in situ an OFDC can potentially go on to hinder speech development.
Although rare, OFDCs should be considered in a differential diagnosis of congenital oral lesions and in particular those of the anterior floor of mouth and tongue. With the use of pre-op imaging to help planning, surgical excision is both diagnostic and therapeutic.

Abstract
Background:IgG4-related disease (IgG4-RD) is an immune-mediated disorder causing fibro-inflammatory lesions. Although the cause remains unknown, it may be driven by interactions between B lymphocytes and CD4+ cytotoxic and regulatory T cells and is characterized by an increase in short-lived plasmablasts, circulating antibodies, and macrophages. Standard therapy mainly includes glucocorticoids (GC), limited by toxicity with long-term use (> 6 mo), and to a lesser extent, immunosuppressives (eg, rituximab). Bruton tyrosine kinase (BTK) plays an important role in the activation of multiple immune effector cells such as B cells, mast cells, eosinophils, basophils, monocytes/macrophages, and neutrophils. Dysregulation of the activation of these immune cells results in autoimmune inflammation, tissue damage, and development of fibrosis. Rilzabrutinib is a highly selective oral BTK inhibitor that targets multiple pathways of innate and adaptive immunity (with direct effects on B-cell and FcR pathways) and has the potential to inhibit antigen presentation to autoreactive T cells.Objectives:To provide the biological rationale for rilzabrutinib in IgG4-RD.Methods:Rilzabrutinib has been evaluated in biochemical, in vitro studies, and in vivo models of inflammatory diseases. Additional support is provided by the phase 2 trial for oral rilzabrutinib in patients with pemphigus vulgaris and the phase 2 trial for oral rilzabrutinib in patients with immune thrombocytopenia (ITP).Results:Rilzabrutinib inhibited the activity of BTK and B-cell receptor in B cells (IC50 5-123 nM) and Fc gamma receptor in IgG/Fc gamma receptor-stimulated monocytes (IC50 56 nM) and blocked IgG- and IgM-mediated antibody production in enriched B cells when stimulated in T-cell dependent (anti-CD40+IL-21) and T-cell independent (TLR-9/CpG and TNP-LPS) pathways. The impact of rilzabrutinib on innate cell pathways was further confirmed by significant dose-dependent inhibition of macrophage and neutrophil-driven passive rat Arthus reaction (P < 0.01 vs vehicle) and antibody-induced murine ITP (P < 0.05 vs vehicle). In a 12-week phase 2 pemphigus vulgaris trial, 54% of patients achieved the primary endpoint, control of disease activity (CDA) on low-dose corticosteroids by week 4, and 73% achieved it by week 12. In the phase 2 trial of ITP patients (median 6 prior therapies), rilzabrutinib 400 mg bid showed rapid and sustained improvement in platelet counts and only grade 1/2-related adverse events1. In responders, platelet counts increased as early as day 8, potentially due to innate immune mechanisms. Collectively, results in both B and innate immune cells provide an initial basis for evaluating rilzabrutinib in IgG4-RD. The ongoing phase 2a study (NCT04520451) is investigating rilzabrutinib 400 mg bid (+tapered GC) vs GC control (3:1) for 12 weeks in IgG4-RD patients refractory to rituximab. The primary objective is to evaluate the safety and ability of rilzabrutinib to induce GC-free remission at week 12. Coupled with known preclinical/clinical findings, mechanistic analyses in this ongoing IgG4-RD study will profile B and other immune cell effects pre-/post-rilzabrutinib dosing to enhance the clinical understanding of rilzabrutinib in IgG4-RD.Conclusion:Studies of rilzabrutinib that show beneficial effects on both B-cell and innate cell pathways provide support for its therapeutic role in immune-mediated diseases and for targeting the underlying pathophysiological effects of IgG4-RD. Effective and safe therapies that rapidly induce and maintain clinical responses, while minimizing the need for continuous GC treatment, remain an unmet need for patients with IgG4-RD.References:[1]Kuter et al.

Abstract
Background:Venous thromboembolism (VTE) includes thrombotic disease of venous system, but primarily includes lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE). Population-based epidemiological studies have shown an association between systemic autoimmune diseases and VTE[1]. The Padua prediction score(PPS) is a new 20-point risk assessment model proposed by Professor Barbar et al[2] in 2010. A large number of researches have shown that low serum albumin concentration is associated with an increased risk of VTE [3],but there is a lack of studies on serum albumin in VTE, and there are no reports on PPS in rheumatology inpatients.Objectives:To investigate the status of VTE in patients in the department of rheumatology, and to explore the value of PPS combined with serum albumin in the identification of VTE in this patient population.Methods:Baseline data of inpatients in rheumatology department were collected at Sichuan Provincial People’s Hospital from September 2018 to September 2020. Occurrence of VTE was compared between high and low risk groups. PPSs were analyzed in VTE and non-VTE patients. Multivariate logistic regression was used to analyze the independent risk factors of VTE. The receiver operating characteristic curve was used to evaluate the probablity of value of rheumatic inpatients with VTE assessed by PPS,serum albumin and PPS with serum albumin. P<0.05 indicates that the difference was statistically significant.Results:A total of 2282 patients were included in this study, and 50(2.2%) had symptomatic VTE. Among the symptomatic VTE cases,38(1.6%) had DVT only,8(0.4%) had PE only, and 4(0.2%) were diagnosed with DVT and PE. PPSs in VTE and non-VTE groups were 3.00(2.00~6.00) and2.00(1.00~2.00) respectively (P< 0.05). One hundred and eighty-eight cases was divided into high-risk group of VTE (PPS≥4), while 2094 cases (PPS<4) were in the low-risk group. Logistic regression analysis showed that known thrombophilic condition, history of VTE, reduced mobility, and D-dimer were independent risk factors of VTE in rheumatology patients, the odd ration(OR) values were 161.90, 26.08, 8.73,and1.04. Serum albumin was the independent protection factor [OR= 0.92(95%CI:0.87~0.98)]. The AUC of PPS model, serum albumin model and the combined predictive model were 0.77, 0.75, 0.84, respectively. The difference between the combined prediction model and PPS model was statistically significant (Z=3.813, P<0.05). The optimal sensitivity of PPS and serum albumin models is 60%, 82%, respectively, and the optimal specificity of is 82.5%,58.6%, respectively. The combination model corresponds to a sensitivity of 62% and a specificity of 90.4%.Conclusion:The incidence of symptomatic VTE was relatively higher in hospitalized patients in rheumatology department. Serum albumin was the protective factor. The combination of albumin and PPS can improve the accuracy of screening for VTE in rheumatology in-patients.References:[1]Tamaki H,Khasnis A.Venous thromboembolism in systemic autoimmune diseases: A narrative review with emphasis on primary systemic vasculitides.[J].Vasc Med, 2015, 20: 369-76.[2]Barbar S, Noventa F, Rossetto V,et al.

Abstract
SETTING: In South Africa prior to 2016, the standard treatment regimen for multidrug- and rifampicin-resistant tuberculosis (MDR/RR-TB) was 24 months long and required daily injectable aminoglycoside (IA) treatment during the first 6 months. Recent evidence supports the replacement of IA with well-tolerated oral bedaquiline (BDQ) and a shortened 9-12 month regimen.DESIGN: Using a Markov model, we analyzed the 5-year budgetary impact and cost per successful treatment outcome of four regimens: 1) IA long-course, 2) oral long-course, 3) IA short-course, and 4) oral short-course. We used the South African MDR/RR-TB case register (2013-2015) to assess treatment outcomes for the then-standard IA long-course. Data on the improvement in outcomes for BDQ-based regimens were based on the literature. Costs were estimated from the provider perspective using costs incurred to provide decentralized treatment for MDR-TB at a Johannesburg hospital.RESULTS: Based on our analysis, by 2023, the cost/successful outcome for the four regimens was respectively 1) US$7374, 2) US$7860, 3) US$5149, and 4) US$4922. The annual total cost of each regimen was US$37 million, US$43 million, US$26 million, and US$28 million.CONCLUSION: Despite the high cost of BDQ, a BDQ-based shortened regimen for the treatment of MDR/RR-TB will result in improved treatment outcomes and cost savings for South Africa.

Abstract
VicRK (WalRK or YycFG) is a conserved 2-component regulatory system (TCS) that regulates cell division, cell wall biosynthesis, and homeostasis in low-GC Gram-positive bacteria. VicRK is also associated with biofilm formation of Streptococcus mutans on the tooth surface as it directly regulates the extracellular polysaccharide (EPS) synthesis. Of the 2 components, VicK possesses both autokinase and phosphatase activities, which regulate the phosphorylation and dephosphorylation of the regulator VicR in response to environmental cues. However, the dual mechanism of VicK as the autokinase/phosphatase in regulating S. mutans' responses is not well elucidated. Previously, it has been shown that the phosphatase activity depends on the PAS domain and residues in the DHp domain of VicK in S. mutans. Specifically, mutating proline at 222 in the PAS domain inhibits VicK phosphatase activity. We generated a VicKP222A mutant to determine the level of VicR-P in the cytoplasm by Phos-tag sodium dodecyl sulfate polyacrylamide gel electrophoresis. We show that in VicKP222A phosphatase, attenuation increased phosphorylated VicR (VicR-P) that downregulated glucosyltransferases, gtfBC, thereby reducing the synthesis of water-insoluble polysaccharides (WIS-EPS) in the biofilm. In addition, VicKP222A presented as long-rod cells, reduced growth, and displayed asymmetrical division. A major adhesin of S. mutans, SpaP was downregulated in VicKP222A, making it unable to agglutinate in saliva. In summary, we have confirmed that VicK phosphatase activity is critical to maintain optimal phosphorylation status of VicR in S. mutans, which is important for cell growth, cell division, EPS synthesis, and bacterial agglutination in saliva. Hence, VicK phosphatase activity may represent a promising target to modulate S. mutans' pathogenicity.

Abstract
Background:Rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and syndrome(SS) are common rheumatic diseases with high incidence. Patients with those rheumatic diseases are at high risk of tuberculosis (TB) infection. However, manifestations can be atypical and easily confused with those of rheumatic disease itself. For those patients, diagnosis is usually much more difficult and further make treatment delayed. Sometimes it may lead to mistreatment. Therefore, it is important to recognize the clinical characteristics of those patients.Objectives:To explore the clinical characteristics and high risk factors of common systemic rheumatism complicated with tuberculosis infection.Methods:A total of 3,906 cases of RA, SLE, and SS common systemic rheumatism diagnosed in the People’s Hospital of Sichuan Province from January 2007 to January 2017 were collected with carefully exclusion with other infectious diseases and neoplastic disease. One hundred and five patients with TB were included as infection group, including 42 cases of RA, 41 cases of SLE, and 22 cases of SS. In the control group, 84 patients with RA, 82 patients with SLE, and 44 patients with SS were randomly selected from the corresponding rheumatoid non-infected patients hospitalized during the same period.Results:Fever was the most common symptom among 42 cases of RA, 41 cases of SLE, and 22 cases of SS with TB, accounting for 83.3%, 92.7%, and 68.2%, respectively. Cough, weight loss or fatigue was less common. For 41 cases of SLE and 22 cases of SS with TB, the proportion of pulmonary was 46.3%, 59.01%, respectively.In TB infection group, 27 cases of RA, 21 cases of SLE, and 13 cases of SS with TB had two or more chest CT findings, accounting for 59%, 57%, 62%, respectively. Lesions located in the posterior or posterior segment which TB usually affected were 9 cases(33.3%),9cases(42.9%),6cases(27.2%),respectively.The daily average dose of hormones within 1 year in TB infection group was higher than that in the control group (P<0.05). For SLE patients, lower counts of CD4+TL were found in TB infection group (P<0.05), while no such differences were found in RA and SS group.Conclusion:Patients with RA who have TB infection are mainly pulmonary TB. For SLE and SS patients, the chance of pulmonary tuberculosis and extra-pulmonary tuberculosis is similar.Symptoms of RA, SLE, SS with TB, such as fever, cough, weight loss, fatigue, are similar with the primary disease or other infection. Chest imaging is diversity. It is difficult to diagnose.Daily average dose of hormone within one year may be a common risk factor for RA, SLE and SS patients with TB. Decreased CD4+TL may also be a risk factor for SLE patients with TB.References:[1]Cantini F, Nannini C, Niccoli L, et al.

Abstract
Background:The incidence of primary Sjögren’s syndrome(pSS) is increasing gradually,and it was ranking second among connective tissue diseases(CTDs)in China.Studies recently have shown that many patients with various CTDs have sleep disturbances,which seriously degraded the patient’s quality of life.As well known, Sleep is an important physiological process to maintain human metabolism, tissue repair,and homeostasis. At present,there are relatively several studies on sleep quality in patients with Rheumatoid arthritis(RA)and Systemic lupus erythematosus(SLE),but less reports on pSS in China have been published.Therefore,it is important to explore the quality of sleep and its influencing factors in such patients.Objectives:The purpose of this study is to evaluate the quality of sleep and related factors in China Mainland patients with primary Sjögren’s syndrome(pSS),and to provide reference and theoretical basis for constructing targeted sleep interventions and improve their quality of life.Methods:A all of 103 pSS patients and 40 matched healthy controls were enrolled in a comparative study of sleep quality using the Pittsburgh Sleep Quality Index(PSQI),and demographic,clinical,and laboratory data were collected from them.The patients completed questionnaires on the European League Against Rheumatism (EULAR)SS Patient Reported Index(ESSPRI), EULAR SS Disease Activity Index (ESSDAI),Xerostomia inventory(XI)with the help of researchers,Pain and fatigue were evaluated with a 100-mm visual analogue scale(VAS).Generalized Anxiety Disorder(GAD-7) and Patient Health Questionnaire(PHQ-9) were used to assess anxiety and depression separately,and whether they have autonomic symptoms (such as sweating, palpitations.)will be asked.Results:The PSQI score and the frequency of poor sleep quality(PSQI>7) were higher in the pSS patients (11.60±5.03,71.8%)than the healthy controls(5.98±3.85,25%).Poor sleepers had a significantly higher GAD-7,PHQ-9,XI,ESSPRI,pain and fatigue VAS,and longer disease duration than good sleepers.Additionally, poor sleepers show more frequent autonomic symptoms.Sleep quality of patients with pSS was positive correlated with GAD-7,PHQ-9,XI,ESSPRI,pain and fatigueVAS scores,but no correlation with disease activity.Meanwhile,depression is a independent factor of sleep quality.Conclusion:Our study showed that the sleep disturbance seen in patients with pSS may contribute to the depression associated with this disease,Future research should investigate that whether antidepressant treatment improve sleep and directly improve quality of life.References:[1]AustadC, Kvien TK, Olsen I C.Sleep disturbance in patients with rheumatoid arthritis is related to fatigue, disease activity,and other patient-reported outcomes[J].

Abstract
This paper investigates the effect of the COVID-19 outbreak and closure of dental practices on the frequency and severity of dental infections presenting in our emergency department. We compared the mean number of daily emergency department referrals for dental abscesses in the two weeks prior to and following the Chief Dental Officer's statement advising general dental practitioners to cease routine appointments, the mean number decreased from 1 to 0.37. In contrast, the severity and requirement for admission of these infections rose from 35% to 80%. This highlights the importance of the provision of local urgent dental centres during the COVID-19 outbreak in order to reduce pressure on secondary and tertiary care centres.

Abstract
Objective: To investigate the effect of HLA-DP gene expression on the susceptibility and disease status of neuromyelitis optica spectrum disorders (NMOSD). Methods: A total of 86 NMOSD patients (52 in acute phase and 34 in remission phase), 52 multiple sclerosis (MS) patients (20 in acute phase and 32 in remission phase) diagnosed in Department of Neurology, the Third Affiliated Hospital of Sun Yat-sen University and 29 healthy controls were enrolled prospectively. Genotyping of HLA-DP was performed. The expression levels of HLA-DP molecules in peripheral blood B cells and monocytes were measured by flow cytometry. The transcription levels of HLA-DPB1 mRNA in peripheral blood mononuclear cells (PBMC) were measured by real time-PCR. The results were compared among different groups Results: There was no statistically significant difference of the distributions of HLA-DPB1*0501/HLA-DPB1*0501, HLA-DPB1*0501/X and X/X genotypes and the frequencies of allele of HLA-DPB1*0501 among NMOSD, MS patients and healthy controls (P=0.96 and 0.71, respectively). The expression levels of HLA-DP on the surface of B cells in NMOSD patients, especially in remission phase patients, were significantly higher than those in healthy controls(212±328 and 374±394 vs 55±57, P=0.049 and 0.002, respectively). The expression levels of HLA-DP on the surface of monocytes in NMOSD patients in acute phase were significantly higher than those in healthy controls(158±175 vs 65±90, P=0.025). The transcription levels of PMBC HLA-DPB1 mRNA in acute phase and remission phase of NMOSD patients were significantly higher than those in healthy controls (3.0±1.4 and 2.9±1.3 vs 1.5±1.4, P=0.000 and 0.003, respectively). The expression levels of HLA-DP molecules on the surface of peripheral blood B cells and monocytes and the transcription levels of PMBC HLA-DPB1 mRNA in MS patients at the acute and remission stages were not significantly different from those in healthy controls. The expression levels of HLA-DP molecules on the surface of B cells in patients with HLA-DPB1*0501/HLA-DPB1*0501, HLA-DPB1*0501/X and X/X genotypes were statistically different (P=0.017). Conclusion: HLA-DP gene transcription and molecular expression levels in antigen presenting cells may affect the susceptibility and disease status of NMOSD patients, while HLA-DPB1*0501 allele may affect the transcription and molecular expression levels of HLA-DP gene in antigen presenting cells.
