Abstract
Objective: To investigate a modified fusional convergence parameter-total convergence amplitude/distance angle and its relationship with exotropia control, stereoacuity, and other visual functions in intermittent exotropia. Methods: The cross-sectional study included children diagnosed with intermittent exotropia at the First Affiliated Hospital of Nanjing Medical University from August 2020 to June 2021. A modification was made by combining total convergence amplitude using synoptophore and distance angle at distance using prism bars to calculate total convergence amplitude/distance angle. Exotropia control at distance and near measured by Office-based Scale for Assessing Control was classified as good control (scale 0-1) and poor control (scale 2-5). Statistical analysis was performed using Spearman correlation analysis, Mann-Whitney U test, Fisher's exact test, χ2 test, logistic regression analysis, and mediation effect analysis. Results: The study included 212 patients, of which 105 (49.5%) were male and 107 (50.5%) were female. The median (interquartile range) age was 9.0 (8.0, 10.0) years. Of 211 cases, 201 (94.8%) had binocular fusional function, while 11 cases (5.2%) did not have binocular fusional function. Among patients with binocular fusional function, inverse correlation was observed between total convergence amplitude and exotropia control scores for both distance (r=-0.427, P<0.001) and near (r=-0.194, P=0.006). Total convergence amplitude/distance angle was an independent predictive factor for exotropia control at distance (OR=0.195; 95%CI, 0.060-0.630; P=0.006) and near (OR=0.252; 95%CI, 0.085-0.746; P=0.013). Stereoacuity at distance (OR=3.110; 95%CI, 1.311-7.379; P=0.010) and near (OR=2.780; 95%CI, 1.401-5.517; P=0.003) were also factors associated with distance exotropia control. Mediation analysis revealed that stereoacuity was not a mediating factor between the ratio and distance control (distance: P=0.066; near: P=0.181). In patients with ratio≥1.5 °/PD, all the 15 patients demonstrated good control. On the contrary, patients with ratio<1.5 °/PD showed worse exotropia control (distance: P=0.001; near: P=0.040) and larger angles of deviation (distance: P<0.001; near: P<0.001). Conclusion: The modified fusional ratio, total convergence amplitude/distance angle, combining synoptophore and prism bars, could be used to evaluate the severity of intermittent exotropia. A higher ratio may be associated with poorer exotropia control. Though it may also be associated with distance exotropia control, stereoacuity is not the mediating factor between the modified ratio and distance exotropia control.

Abstract
INTRODUCTION Baricitinib is an oral, selective inhibitor of Janus kinase which demonstrates clinical efficacy in patients with rheumatoid arthritis (RA). This report aims to analyze the onset time of baricitinib in Chinese patients with moderately to severely active RA who had an inadequate response to methotrexate. METHODS This post hoc analysis evaluated clinical improvements of Chinese patients treated with baricitinib 4 mg once daily compared with placebo, based on data from a phase 3 study RA-BALANCE. Efficacy measures including American College of Rheumatology 20% (ACR20) response, ACR core set values, Disease Activity Score modified to include the 28 diarthrodial joint count (DAS28) using high-sensitivity C-reactive protein (hsCRP), DAS28-erythrocyte sedimentation rate, Simplified Disease Activity Index, Clinical Disease Activity Index, DAS28-hsCRP ≤ 3.2 response (low disease activity), and Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) were evaluated at weeks 1, 2, 4, 8, 12, 14, 16, 20, and 24 (except for FACIT-F evaluated every 4 weeks). A logistic regression model and an analysis of covariance model were used to analyze treatment comparisons of categorical and continuous measures, respectively. RESULTS Statistically significant (p ≤ 0.05) improvements were observed as early as week 1 or 2 for the baricitinib group compared to placebo in almost all main efficacy measures. For other outcomes including 66 swollen joint count, 68 tender joint count, FACIT-F, and DAS28-hsCRP ≤ 3.2 response rate, differences were evident (p ≤ 0.05) by week 4 in the baricitinib group compared with placebo. Significant improvements in all efficacy measures were sustained through 24 weeks. CONCLUSIONS Baricitinib demonstrated a rapid onset of efficacy on ACR20 response, ACR core set values, disease activity, and patient-reported outcome improvements in Chinese patients from RA-BALANCE. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT02265705.

Abstract
OBJECTIVE Changes in gut microbiota have been linked to systemic lupus erythematosus (SLE), but knowledge is limited. Our study aimed to provide an in-depth understanding of the contribution of gut microbiota to the immunopathogenesis of SLE. METHODS Fecal metagenomes from 117 patients with untreated SLE and 52 SLE patients posttreatment were aligned with 115 matched healthy controls and analyzed by whole-genome profiling. For comparison, we assessed the fecal metagenome of MRL/lpr mice. The oral microbiota origin of the gut species that existed in SLE patients was documented by single-nucleotide polymorphism-based strain-level analyses. Functional validation assays were performed to demonstrate the molecular mimicry of newly found microbial peptides. RESULTS Gut microbiota from individuals with SLE displayed significant differences in microbial composition and function compared to healthy controls. Certain species, including the Clostridium species ATCC BAA-442 as well as Atopobium rimae, Shuttleworthia satelles, Actinomyces massiliensis, Bacteroides fragilis, and Clostridium leptum, were enriched in SLE gut microbiota and reduced after treatment. Enhanced lipopolysaccharide biosynthesis aligned with reduced branched chain amino acid biosynthesis was observed in the gut of SLE patients. The findings in mice were consistent with our findings in human subjects. Interestingly, some species with an oral microbiota origin were enriched in the gut of SLE patients. Functional validation assays demonstrated the proinflammatory capacities of some microbial peptides derived from SLE-enriched species. CONCLUSION This study provides detailed information on the microbiota of untreated patients with SLE, including their functional signatures, similarities with murine counterparts, oral origin, and the definition of autoantigen-mimicking peptides. Our data demonstrate that microbiome-altering approaches may offer valuable adjuvant therapies in SLE.

Abstract
e12502 Background: To explore the prognostic value of pretherapeutic peripheral blood parameters and breast imaging-reporting and data system (BI-RADS) classification of triple-negative breast cancer (TNBC) and the effect of postoperative radiotherapy in early cases. Methods: A total of 278 TNBC patients’ medical records between January 2013 and December 2018 were retrospectively collected, including white blood cells, neutrophils, lymphocytes, platelets, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), serum tumor markers, BI-RADS classification, TNM staging and therapeutic methods. We used the log-rank test and Kaplan-Meier curves to assess the progression-free survival (PFS) of enrolled patients. Multivariate prognostic analysis was performed by the Cox regression model. Results: The median PFS of all 278 patients was 20 months (4-72 months) at the end of follow-up. Operable patients who obtained adjuvant chemotherapy had a better median PFS (20 vs 18.5 months, P= 0.018, HR = 5.943, 95% CI: 1.36-25.92) than those without. Lymph node metastasis (52%) and chest well relapse (28%) were the critical failure forms followed by other metastases (12% lungs, 9.3% bones, 4% liver and 2.7% brain) with p value less than 0.001. Multivariate analysis indicated that platelet counts > 113.5×109/L (p = 0.024), PLR ≤ 111.7 (p = 0.036) and CA15-3 ≤ 8.4 U/mL (p = 0.003) were significantly associated with the favourable prognosis of PFS in TNBC patients. Furthermore, BI-RADS of grade 2-4 had a better median PFS compared with grade of 5-6(20 vs 17.5 months, p = 0.008, HR = 2.154, 95% CI: 1.219-3.805). In subgroup analysis, forty-three early cases with pN1 stage earned additional benefits from postoperative radiotherapy in terms of low risk of distant metastasis and recurrence (p = 0.014). Residual tumor after surgery was another important factor of poor prognosis (p = 0.029). Conclusions: Adjuvant chemotherapy improved median PFS for operable TNBC patients and pretherapeutic platelets, PLR, CA15-3 and BI-RADS were the independent prognostic factors of survival. Lymph node metastasis and chest well relapse were the main patterns of treatment failure. Radiotherapy could reduce the risk of disease progression for postoperative patients with N1 stage.

Abstract
OBJECTIVE To analyze the expression profile of serum cytokines in patients with systemic sclerosis (SSc) and explore its possible regulatory mechanisms. METHODS Serum and DNA of peripheral blood mononuclear cells were collected from 30 SSc patients and 80 normal controls (NCs). According to the presence or absence of interstitial lung disease (ILD) in SSc, the patients were divided into SSc with ILD group and SSc without ILD group. According to the degree of skin involvement, the patients were divided into diffuse systemic scleroderma (dcSSc) group and limited systemic scleroderma (lcSSc) group. According to the presence of anti-topoisomerase-1 antibody (anti-Scl-70 antibody) in the serum of patients with SSc, they were divided into SSc Scl-70 (+) group and SSc Scl-70 (-) group. 27 cytokines in serum were detected by Luminex MAGPIX detection system and Bio-Plex Pro Human Cytokine 27-plex Assay kit: interleukin-1β (IL-1β), interleukin-1 receptor antagonist (IL-1ra), IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12P70, IL-13, IL-15, IL-17, basic fiber growth factor (BASIC FGF), eotaxin, granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor (GM-CSF), interferon-γ (IFN-γ), interferon-gamma induced protein 10(IP-10), monocyte chemotactic protein 1(MCP-1), macrophage inflammatory protein-1α (MIP-1α), macrophage inflammatory protein 1β(MIP-1β), platelet-derived growth factor BB (PDGF-BB), regulated on activation in normal T-cell expressed and secreted (RANTES), tumor necrosis factor-α (TNF-α), and vascular endothelial growth factor(VEGF). Methylation sites were detected by Illumina 450K methylation chip. RESULTS Compared with NCs group, the expression of 12 cytokines (BASIC FGF, eotaxin, G-CSF, GM-CSF, IFN-γ, IL-1β, IL-1ra, IL-6, IP-10, MCP-1, TNF-α and RANTES) in the SSc group significantly increased (P<0.05), IL-5 was decreased expression in the SSc group (P<0.05), there was no significant difference in the expressions of the other 14 cytokines. Compared with lcSSc group, 9 cytokines (eotaxin, IL-5, MCP-1, IL-2, RANTES, IL17A, IL-8, MIP-1β and PDGF-BB) increased in dcSSc group, but there was no significant difference. Compared with SSc without ILD group, IL-15 increased in SSC with ILD group [18.2 (172.97) ng/L vs. 2.03(0.05) ng/L, P<0.05]. Compared with SSc Scl-70 (-) group, the expression of IP-10 decreased in SSc Scl-70 (+) group [1 030 (2 196.6) ng/L vs. 1 878 (2 964) ng/L, P<0.05]. The correlation analysis of serum cytokines with erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) showed that IL-6 was positively correlated with ESR (r =0.04, P= 0.017), MCP-1 (r=0.49, P=0.043) and MIP-1β (r=0.41, P=0.007) positively correlated with CRP. By analyzing the changes of methylation sites of cytokines, it was found that cg17744604 in IL-10 TSS1500 region, cg06111286 in IL-12P70 TSS200 region, cg07935264 in IL-1β TSS200 region, cg01467417 in IL-1ra TSS1500 region, cg03989987 in IL-1ra 5'UTR region and cg21099624 in VEGF TSS200 region were all hypomethylated. CONCLUSION There were different cytokines expression profiles in the serum of SSc patients, and the altered cytokines were correlected with the degree of skin damage and pulmonary fibrosis. Many cytokines were regulated by methylation.

Abstract
Systemic lupus erythematosus (SLE) is a highly heterogeneous autoimmune disease, characterized by production of pathogenic autoantibodies and wide involvement of multiple systems. Damageofimmune tolerance and imbalance of immune homeostasis lead to the production of autoantibodies and the injuries of multiple organs and systems. In recent years, plenty of studies have identified that immunometabolism affects survival status of certain cells, also cell activation, differentiation and effector functions. Conversely, immune cells with different functions or differentiational status upregulate specific metabolic pathways to maintain their identities. In response to outer stimulations, naive immune cells differentiate into activated cells, accompanied with a series of immunometabolism changes. Therefore, abnormal immunometabolism can induce global imbalance of immune homeostasis, which further results in the initiation and development of autoimmune diseases, including SLE. Multiple abnormalities of immunometabolism have been found in patients with SLE or mouse models of lupus. Immune cells involved in the development of SLE, such as T cells, B cells, dendritic cells and macrophages present various metabolic abnormalities and pathological phenotypes. Among these cells, CD4+ T cells play predominant roles in the pathogenesis of SLE. Lots of studies demonstrated that CD4+ T cells and their subsets were in abnormal immunometabolic status,which further resulted in the development of SLE. In CD4+ T cells from patients with SLE or mouse models of lupus, both levels of glycolysis and oxidative phosphorylation are significantly higher compared with healthy controls. However,mitochondrial abnormalities, decreased ATP production and increased level of oxidative stress also have been found in these cells, which play important roles in the production of reactive oxygen intermediates and autoantibodies. Aggregated lipids rafts and increased synthesis of glycosphingolipid and cholesterol also have been observed in the CD4+ T cells from patients with SLE, leading to the abnormally elevated TCR signaling. Moreover, mechanistic target of rapamycin (mTOR) signaling is activated in the CD4+ T cells from both patients with SLE or mouse models of lupus and participate in the metabolic abnormalities of pathological CD4+ T cells. Progressive understanding of immunometabolism give us new insights of the pathogenesis of SLE and provide us with more therapeutic targets in the treatment of SLE.

Abstract
Objective: To investigate the demographic characteristics, clinical features, diagnosis and treatment of patients with gout in China. Methods: Clinical data of 6 814 patients with gout from 100 hospitals in 27 provinces, municipalities or autonomous regions in China were collected and analyzed. Results: (1) The ratio of male to female in patients with gout was 14.7∶1. The mean age of onset was (48.8±15.1) years old. Mean serum urate level was (526.7±132.3) μmol/L. Patients' education background was of U-shaped distribution; (2) Hypertension was the most common comorbidity [15.8%(1 079/6 814)], then overweight or obesity [51.9%(3 536/6 814)]; (3) Alcohol and high-purine food intake were dominant triggering factors in men. The diagnosis of gout was made after onset in majority of patients with cardinal symptom arthralgia. Most patients had the disease less than 5 years, and the longer the course, the more flares in the previous year of entry; (4) Febuxostat was the mostly used urate-lowering medication. 20.7%(1 412/6 814), 10.8%(739/6 814) and 3.9%(265/6 814) of patients were followed up in 4 weeks, 12 weeks and 24 weeks after registration, and 18.9%(267/1 412), 29.1%(215/739) and 38.1%(101/265) of them reached the control target of serum urate levels, respectively. After treatment, patients' liver function was not affected, but serum creatinine levels decreased significantly. Conclusions: The proportion of gout patients who reach target serum urate level is very low. Further steps including education and survey need to be carried on.

Abstract
Cardiomyocytes can resist ischemia/reperfusion (I/R) injury through ischemic postconditioning (IPoC) which is repetitive ischemia induced during the onset of reperfusion. Myocardial ischemic preconditioning up-regulated protein 2 (MIP2) is a member of the WD-40 family proteins, we previously showed that MIP2 was up-regulated during ischemic preconditioning (IPC). As IPC and IPoC engaged similar molecular mechanisms in cardioprotection, this study aimed to elucidate whether MIP2 was up-regulated during IPoC and contributed to IPoC-mediated protection against I/R injury. The experiment was conducted on two models, an in vivo open chest rat coronary artery occlusion model and an in vitro model with H9c2 myogenic cells. In both models, 3 groups were constituted and randomly designated as the sham, I/R and IPoC/hypoxia postconditioning (HPoC) groups. In the IPoC group, after 45 min of ischemia, hearts were allowed three cycles of reperfusion/ischemia phases (each of 30 s duration) followed by reperfusion. In the HPoC group, after 6 h of hypoxia, H9c2 cells were subjected to three cycles of 10 minute reoxygenation and 10 minute hypoxia followed by reoxygenation. IPoC significantly reduced the infarct size, plasma level of Lactate dehydrogenase and creatine kinase MB in rats. 12 h after the reperfusion, MIP2 mRNA levels in the IPoC group were 10 folds that of the sham group and 1.4 folds that of the I/R group. Increased expression of MIP2 mRNA and attenuation of apoptosis were similarly observed in the HPoC group in the in vitro model. These effects were blunted by transfection with MIP2 siRNA in the H9c2 cells. This study demonstrated that IPoC induced protection was associated with increased expression of MIP2. Both MIP2 overexpression and MIP2 suppression can influence the IPoC induced protection.

Abstract
Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK) is a recently identified proinflammatory cytokine of the TNF superfamily. Studies have indicated that TWEAK plays an important role in renal, vascular injury and immune disease. The aim of this study was to explore the expression of the TWEAK in peripheral blood mononuclear cells (PBMCs) and analyze the correlation between TWEAK and disease activity and renal damage of SLE. The expression of TWEAK in PBMCs was determined by RT-PCR and western blot. SLE disease activity was evaluated by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) 2000 score. Next were analyzed the correlations of TWEAK mRNA and protein to serum IL-10, MCP-1 and some laboratory parameters of SLE disease activity. Subjects comprised 48 patients with SLE including 25 patients with renal damage and 23 without, 20 patients with rheumatoid arthrithis (RA) and 15 healthy controls. The results showed that TWEAK expressions in PBMCs from SLE patients were significantly higher than that in RA patients or healthy controls, especially higher in those patients with renal disease. Elevated production of TWEAK is correlated positively and significantly with SLEDAI, proteinuria, serum anti-dsDNA, IL-10 and MCP-1, but inversely associated with serum complements. Our results suggested that TWEAK in PBMCs is positively related to SLE disease activity and might be involved in the pathogenesis of SLE.

Abstract
We performed a genome-wide association study (GWAS) of systemic lupus erythematosus (SLE) in a Chinese Han population by genotyping 1,047 cases and 1,205 controls using Illumina Human610-Quad BeadChips and replicating 78 SNPs in two additional cohorts (3,152 cases and 7,050 controls). We identified nine new susceptibility loci (ETS1, IKZF1, RASGRP3, SLC15A4, TNIP1, 7q11.23, 10q11.22, 11q23.3 and 16p11.2; 1.77 x 10(-25) < or = P(combined) < or = 2.77 x 10(-8)) and confirmed seven previously reported loci (BLK, IRF5, STAT4, TNFAIP3, TNFSF4, 6q21 and 22q11.21; 5.17 x 10(-42) < or = P(combined) < or = 5.18 x 10(-12)). Comparison with previous GWAS findings highlighted the genetic heterogeneity of SLE susceptibility between Chinese Han and European populations. This study not only advances our understanding of the genetic basis of SLE but also highlights the value of performing GWAS in diverse ancestral populations.

Abstract
OBJECTIVE To investigate the release and intracellular localization of high mobility group box chromosomal protein 1 (HMGB1) in the peripheral blood monocytes of rheumatoid arthritis (RA) patients and the inhibitive effect of thalidomide. METHODS 19 RA patients and 20 healthy controls were included in the study. Monocytes were separated from peripheral blood with Ficoll density gradient centrifugation. Monocytes were treated with 100 ng/ml tumor necrosis factor alpha (TNFalpha) or 100 ng/ml TNFalpha plus 40 microg/ml thalidomide and grown in an incubator at 37 degrees C with 5% CO2 for 24 hours. The culture supernatants of the monocytes were collected. HMGB1 level in the culture medium was detected with Western blot. In addition, the intracellular localization of HMGB1 in the monocytes was investigated with immunocytochemical analysis. RESULTS Without stimulation, the release of HMGB1 protein was significantly increased in the culture supernatants of peripheral blood monocytes from RA patients as compared with that from healthy controls (P < 0.05). TNFalpha (100 ng/ml) did not further increase the release of HMGB1 in the monocytes from the patients with RA. Thalidomide (40 microg/ml) could inhibit the release of HMGB1 in the monocytes from RA patients stimulated with TNFalpha (P < 0.05). In the monocytes from RA patients, HMGB1 was mainly localized in the nucleus. Treatment with TNFalpha (100 ng/ml) for 24 hours resulted in a cytoplasmic translocation of HMGB1, which was inhibited significantly by thalidomide. CONCLUSION TNFalpha induces the release and cytoplasmic translocation of HMGB1 in the peripheral blood monocytes of RA patients and thalidomide inhibits the release and translocation of HMGB1.

Abstract
Members of the heat shock factor (HSF) family are evolutionarily conserved regulators that share a highly homologous DNA-binding domain. In mammals, HSF1 is the main factor controlling the stress-inducible expression of Hsp genes while the functions of HSF2 and HSF4 are less clear. Based on its developmental profile of expression, it was hypothesized that HSF2 may play an essential role in brain and heart development, spermatogenesis, and erythroid differentiation. To directly assess this hypothesis and better understand the underlying mechanisms that require HSF2, we generated Hsf2 knockout mice. Here, we report that Hsf2(-/-) mice are viable and fertile and exhibit normal life span and behavioral functions. We conclude that HSF2, most probably because its physiological roles are integrated into a redundant network of gene regulation and function, is dispensable for normal development, fertility, and postnatal psychomotor function.
