Abstract
Objective: To investigate the clinicopathological characteristics and prognosis of sporadic multiple primary gastrointestinal stromal tumor (GIST). Methods: A retrospective cohort study was conducted. Case inclusion criteria: (1) postoperative pathological diagnosis of GIST; (2) primary GIST with single lesion or sporadic multiple primary GIST (sporadic GIST was defined as primary GIST other than familial and syndrome-related GIST, and multiple primary GIST was defined as the number of primary GISTs in the same patient ≥ 2); (3) patients with complete clinicopathological data. Those with tumor recurrence or distant metastasis, and with other malignancies were excluded. Medical records of patients with primary GIST who underwent surgical resection in the Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2010 to December 2020 were collected. Patients were divided into sporadic multiple primary GIST group and single primary GIST group according to the number of primary GIST lesions. The clinicopathological data and prognosis of the two groups were observed and compared. Results: A total of 1200 patients with primary GIST were enrolled in this study, including 628 males (52.3%) and 572 females (47.7%), with a median onset age of 58 (19-93) years. Among them, 1165 cases (97.1%) were sporadic primary GIST with single lesion; 35 cases (2.9%) were sporadic multiple primary GIST. Among 35 cases of sporadic multiple primary GIST, 3 cases (8.6%) had acid reflux as the first symptom, which was higher than the single primary GIST group (22/1165, 1.9%) (χ(2)=7.437, P=0.006). There were no significant differences in other clinical characteristics between the two groups (all P>0.05). Patients in the sporadic multiple primary GIST group contained a total of 80 primary tumors. Compared with the single primary GIST group, the sporadic multiple primary GIST group had a higher proportion of tumors originating in the stomach [87.5% (70/80) vs. 59.1% (689/1165)], lower proportion of spindle cell in histology [85.0% (68/80) vs. 93.7% (1092/1165)], higher proportion of positive CD34 [97.5% (78/80) vs. 87.6% (1021/1165)], smaller maximum diameter [maximum diameter ≤2.0 cm: 61.2% (49/80) vs. 28.8% (335/1165)], lower mitotic rate [≤5/50 high-power fields (HPF): 93.8% (75/80) vs. 74.5% (868/1165)], lower risk of recurrence [60.0% (48/80) vs. 23.3% (271/1165)], and the differences were all statistically significant (all P<0.05). The 3-year recurrence-free survival rate in the sporadic multiple primary group and the single primary GIST group was 96.6% and 89.3% respectively (P=0.160), and the 3-year overall survival rate was 100.0% and 92.8%, respectively (P=0.088). Conclusions: The most common type of sporadic multiple primary GIST is multiple tumors originating in the stomach at the same time. Compared with primary GIST with single lesion, sporadic multiple primary GIST presents smaller maximum diameter and lower mitotic rate. The prognosis of patients between two groups is not significantly different.

Abstract
We have investigated the illumination effect on the magnetotransport properties of a two-dimensional electron system at the LaAlO3/SrTiO3interface. The illumination significantly reduces the zero-field sheet resistance, eliminates the Kondo effect at low-temperature, and switches the negative magnetoresistance into the positive one. A large increase in the density of high-mobility carriers after illumination leads to quantum oscillations in the magnetoresistance originating from the Landau quantization. The carrier density (∼2 × 1012 cm-2) and effective mass (∼1.7me) estimated from the oscillations suggest that the high-mobility electrons occupy thedxz/yzsubbands of Ti:t2gorbital extending deep within the conducting sheet of SrTiO3. Our results demonstrate that the illumination which induces additional carriers at the interface can pave the way to control the Kondo-like scattering and study the quantum transport in the complex oxide heterostructures.

Abstract
Supernumerary teats (SNT) are a common epidermal abnormality of udders in mammals. The SNT negatively affect machine milking ability, udder health, and animal welfare and sometimes act as reservoirs for undesirable bacteria, resulting in economic losses on calves and lactating cows due to the cost of SNT removal surgery, early culling, and low milk yield. This study aimed to analyze the incidence and genetic parameter of SNT and detect SNT-related genes in Chinese Holstein cattle. In this study, the incidence of SNT was recorded in 4,670 Chinese Holstein cattle (born between 2008 and 2017) from 2 farms, including 734 genotyped cows with 114,485 SNPs. The SNT had a total frequency of 9.8% and estimated heritability of 0.22 (SE = 0.07), which were obtained using a threshold model in the studied Chinese Holstein population. Furthermore, we calculated approximate genetic correlations between SNT and the following indicator traits: 12 milk production, 28 body conformation, 5 fertility and reproduction, 5 health, and 9 longevity. Generally, the estimated correlations, such as 305-d milk yield for third parity (-0.55; SE = 0.02) and age at first calving in heifer (0.19; SE = 0.03), were low to moderate. A single-step GWAS was implemented, and 10 genes associated with SNT located in BTA4 were identified. The region (112.70-112.90 Mb) on BTA4 showed the highest genetic variance for SNT. The quantitative trait loci on BTA4 was mapped into the RARRES2 gene, which was previously shown to affect adipogenesis and hormone secretion. The WIF1 gene, which was located in BTA5, was also considered as a candidate gene for SNT. Overall, these findings provide useful information for breeders who are interested in reducing SNT.

Abstract
Abstract
Study question
What causes our patient’s repeated almost complete oocyte maturation arrest (OMA)?
Summary answer
Since we did not detect PATL2 and TUBB8 mutations, both known to cause OMA, this case was likely caused by mutations in HUS1 and ITGB3
What is known already
OMA has been associated with loss-of-function in key genes, such as PATL2 and TUBB8. Such patients have, however, uniformly have been unable to conceive with IVF
Study design, size, duration
We here report the case of repeatedly presenting patient between 2009 until 2020 (age 30 at 1st and 41 at last visit).
Participants/materials, setting, methods
The couple underwent 7 IVF treatments under several ovarian stimulation protocols at different gonadotropin dosages and in different preparations to try to recruit mature eggs. She conceived in her 2nd IVF cycle in 2009 and delivered uneventfully in 2010. She then conceived spontaneously and delivered a healthy boy in 2014. The couple since then has been attempting another pregnancy. Remarkably, in all IVF cycles all eggs but one arrested at prophase.
Main results and the role of chance
The female demonstrates abnormally high ovarian reserve for age (AMH=5.9 ng/mL in 2019) (mean, 10.6 oocytes). In all cycles, all but one retrieved were immature. In vitro maturation rate for the GV oocytes was 28%. Resultant M2s, however, demonstrated morphological abnormalities, such as giant polar bodies. In vivo M2s, in contrast, were always morphologically unremarkable, and their fertilization rate was 85%. Embryo morphology deteriorated appreciatively with advancing age. Sanger sequencing for TUBB8 and PATL2 genes were unremarkable. Whole genome sequencing of her and her sister (who had no fertility problems) revealed mutations of genes belonging to the integrin family (ITGB3) and DNA repair checkpoint (HUS1), both of which could be determinants in the observed maturation arrest.
Limitations, reasons for caution
A functional study, coupled with imaging of the discarded material, will likely offer further information regarding the mechanisms leading to OMA in this female.
Wider implications of the findings: This case report represents a new phenotype of female infertility, characterized by almost complete maturation arrest which, however, still offers opportunity for pregnancy. Further isolation of underlying mutation(s) may offer additional insights about checkpoints required for the transition of prophase to metaphase in human oocytes.

Abstract
BACKGROUND While open approaches have historically been used in the surgical treatment of intradural-extramedullary spine tumors, minimally-invasive surgical (MIS) techniques are frequently applied to minimize post-operative complications associated with open surgery. Tubular retractor systems in particular have been employed in combination with the unilateral hemilaminectomy (UHL) approach. Here we describe the use of a Williams retractor as a safe and effective minimally-invasive alternative to tubular retractor systems with similar post-operative outcomes. METHODS We retrospectively reviewed a cohort of eight patients who underwent unilateral hemilaminectomy using a Williams retractor for the minimally-invasive resection of intradural-extramedullary neoplasms at a large tertiary academic center from 2017 to 2019. Patient demographics, pathologic specimens, radiographic studies, and intraoperative parameters were collected and analyzed. RESULTS In our series, gross total resection was achieved in all cases. Average operative time was 158±40minutes, the mean estimated blood loss (EBL) was 44.4±30.4mL, and mean length of stay was three days. All patients reported symptomatic improvement at follow-up as reported by Visual Analog Scale scores. CONCLUSION A Williams retractor yields similar outcomes with respect to post-operative pain, operative time, and EBL as it maintains the advantages of the UHL approach in the resection of intradural-extramedullary spine tumors while enhancing feasibility and providing significant cost savings.

Abstract
OBJECTIVE The aim of this study was to explore the influence of micro ribonucleic acid (miR)-145-5p on myocardial cell apoptosis in rats with myocardial infarction (MI) through the phosphatidylinositol 3-hydroxy kinase/protein kinase B (PI3K/Akt) pathway. MATERIALS AND METHODS In this study, Sprague-Dawley rats were used as research objects to establish the acute MI model in vivo. Infarction tissues and non-infarction tissues were both collected from rats. The expression level of miR-145-5p was determined using quantitative Polymerase Chain Reaction (qPCR), and the pathological changes in myocardial tissues of rats were observed through hematoxylin-eosin (HE) staining. In addition, H9c2 rat myocardial cells were cultured under hypoxia or normal oxygen concentration to simulate hypoxia in MI tissues. The changes in the expression of miR-145-5p in H9c2 cells in normal oxygen and hypoxia were determined. Meanwhile, the ratio of apoptotic cells to viable cells, and the changes in the expressions of proteins B-cell lymphoma 2 (Bcl-2), Bcl-2 associated X protein (Bax), Caspase-3 and Caspase-9 were evaluated through flow cytometry assay and Western blotting, respectively. The expression levels of crucial proteins in the PI3K/Akt pathway were measured as well. Additionally, H9c2 cells were transfected with miR-145-5p control and miR-145-5p mimic to evaluate cell apoptosis. RESULTS QPCR results revealed that the expression level of miR-145-5p was substantially elevated in MI tissues (p<0.05). HE results indicated that the soma exhibited deformation after MI, suggesting that there were more necrotic and apoptotic cells. Compared with those cultured under normal oxygen concentration, H9c2 cells cultured in hypoxia environment exhibited significantly upregulated expression level of miR-145-5p, downregulated expression level of anti-apoptosis protein Bcl-2, upregulated level of pro-apoptosis protein Bax, activated Caspase-3 and Caspase-9, and downregulated expression level of functional proteins in the PI3K/Akt pathway (p<0.05). Furthermore, the expression levels of apoptosis-associated proteins significantly rose in H9c2 cells transfected with miR-145-5p mimic compared with those transfected with miR-145-5p control, showing statistically significant differences (p<0.05). CONCLUSIONS MiR-145-5p is notably raised in MI tissues of rats. After infarction, there are evidently more apoptotic myocardial cells. The expression of miR-145-5p is markedly elevated in H9c2 rat myocardial cells in hypoxia. Compared with those cultured in normal oxygen, H9c2 cells cultured in hypoxia showed increased apoptosis. The apoptosis of myocardial cells transfected with miR-145-5p mimic is notable higher than that of myocardial cells transfected with miR-145-5p control. Moreover, the expressions of active Akt and PI3K proteins decrease remarkably. The results of this study demonstrate that miR-145-5p inactivates the PI3K/Akt pathway to promote the apoptosis of MI cells.

Abstract
Porcine vertebral and teat numbers are variable and important economic traits in pig production. However, the quantitative trait loci (QTL) and candidate genes for both of these traits in the Beijing Black Pig are not yet known. In the present study, number of vertebrae and number of teats were obtained for 891 individuals of the Beijing Black Pig and genotyped using the Illumina Porcine 50 K BeadChip. Genome scanning was performed to detect associated variants and candidate genes for both traits using a genome-wide association study by tassel software. For vertebral number, 15 significant SNPs were located on SSC7. According to linkage disequilibrium analysis on SSC7, a haplotype block of 221 kb from 97.4 to 97.6 Mb was shown to contain a good candidate gene ABCD4. Interestingly, on SSC12, we recorded a novel QTL containing three significant SNPs and 34 annotated genes from 24.0 to 25.7 Mb for vertebral number. Of the 34 genes, nine Hox family genes (HOXB 1-7, 9, and 13) were found to be good candidate genes. Using the 34 genes, a gene ontology analysis was performed to detect enrichment of anterior/posterior pattern specification. For teat number, a novel chromosome-wide significant QTL was identified on SSC10. In this QTL region, one significant SNP was identified. The nearest gene, NTRK2, was regarded as a candidate gene. The present results expanded the QTL for vertebral and teat numbers and provided useful molecular markers for breeding in the Beijing Black Pig population.

Abstract
Glucocorticoids (GC) are generally envisioned as immunosuppressive, but in conditions such as rosacea and perioral dermatitis they can lead to increased skin inflammation. In lung epithelia, GC promote expression of the pro-inflammatory cytokine CCL20, which contributes to steroid-resistant asthma. In the skin, CCL20 stimulates inflammation by recruiting Th17 T-lymphocytes and dendritic cells and is elevated in papulopustular rosacea. The objective of this study was to understand if and how glucocorticoids affect CCL20 expression in human keratinocytes. CCL20 expression was assessed by quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) and ELISA. Selective inhibition of candidate genes and signaling pathways was performed using RNA interference and chemical inhibitors. The binding of activated glucocorticoid receptor to genomic DNA was determined by chromatin immunoprecipitation, and enhancer activity of genomic sequences was measured with a reporter assay. We found that GC treatment increased CCL20 expression in human keratinocytes and murine skin, both in the undisturbed state and with tumor necrosis factor-α (TNFα) stimulation. GC repressed pro-inflammatory signaling pathways including NFκB and p38/MAPK, but these inhibitory effects were opposed by the direct binding of activated glucocorticoid receptor to the CCL20 enhancer, promoting CCL20 expression. Viewed together, these findings demonstrate a mechanism by which GC induce expression of CCL20 in keratinocytes, which may contribute to the inflammation seen in steroid-exacerbated skin conditions.

Abstract
Objective: To explore the association between polygenic risk score (PRS) and age at onset and early-onset risk of gastric cancer (GC). Methods: Gastric cancer cases from existing genome-wide association study were included, and 112 single nucleotide polymorphisms associated with GC risk were used to derive individual PRS. Analysis of variance and Pearson correlation test was used to depict the relationship between PRS and GC onset age. Cases diagnosed before 50 years old were defined as early-onset gastric cancer. Cox proportional hazard model was used to test the association between PRS and early-onset GC risk with early-onset age as the timescale and low genetic risk (PRS ≤20%) as the reference group. Results: A total of 8 629 cases, including 6 284 males (72.82%) and 2 345 females (27.18%), were included, and the mean age was (60.61±10.80) years old. The PRS was negatively correlated with age of GC onset (r=-0.05, P<0.001). The mean age of gastric cancer cases with low, intermediate, and high genetic risk were (61.68±10.33), (60.53±10.79), (59.80±11.20), respectively. PRS was significantly associated with the risk of early-onset GC in a dose-response manner (intermediate genetic risk: HR=1.19, 95%CI: 1.03-1.39, P=0.022; high genetic risk: HR=1.44, 95%CI: 1.20-1.71, P<0.001). Conclusions: PRS may contribute to the risk of both GC and early-onset GC. PRS can be used as a measurable indicator for risk prediction for occurrence and early-onset of GC.

Abstract
Background:Patients with systemic lupus erythematosus (SLE) have a substantially increased risk of venous thromboembolism (VTE). An individual VTE risk assessment is important to ensure that all patients are assessed and given adequate thromboprophylaxis.Objectives:We conducted this study to develop a risk score for VTE in patients with SLE.Methods:Patients with SLE who participated in the Chinese SLE Treatment and Research group were enrolled in this study. Patient baseline information and clinical laboratory indicators were obtained, and VTE events were recorded every 3-6 months during follow-up visits. The risk prediction model was created and internally validated using the bootstrap methods, and a scoring system was established (Figure 1).Figure 1.Flow chart of study design.Results:Out of 4,502 patients included in this study, 135 had a VTE event. After univariate analysis and Lasso regression, the following 11 variables were identified and included in the risk prediction model: male sex, age, BMI ≥25 kg/m2, hyperlipidemia, hypoalbuminemia, hsCRP>3 mg/L, renal involvement, nervous system involvement, anti-β2-glycoprotein I antibody positivity, lupus anticoagulant positivity, and no use of hydroxychloroquine. The AUC for the SLE-VTE score (Table 1) was 0.947 (95% CI, 0.9249-0.9694). The SLE-VTE score’s sensitivity and specificity with the optimal cutoff value of 13 were 0.919 and 0.881, respectively. The SLE-VTE score was superior to the GAPSS system in predicting the risk of VTE in patients with SLE (AUC= 0.947 vs. 0.680, P< 0.001; integrated discrimination improvement (IDI)= 0.6652, P< 0.001; net reclassification improvement (NRI)= 0.6652, P< 0.001).Table 1.Final multivariable analysis for venous thromboembolism risk in patients with SLE β coefficientsOdds ratio* (95% CI)P-valuePoints in scoring systemMale0.6211.86(0.953-3.503)0.0612Age at study entry(≥50)0.8372.308(1.339-3.915)0.0023BMI02(kg/m20.7922.209(1.333-3.627)0.0023Hyperlipemia0.8382.313(1.246-4.166)0.0063Hypoalbuminemia2.1638.697(5.185-14.794)< 0.0017hsCRP>3 mg/L1.4524.272(2.618-6.968)< 0.0015Anti β2GPI1.0132.754(1.543-4.853)0.0013LA1.5594.752(2.799-8.072)< 0.0015Nervous system2.38210.832(6.163-18.998)< 0.0018Lupus nephritis0.8352.305(1.414-3.756)0.0013No use of hydroxychloroquine1.7715.876(3.722-9.401)< 0.0016BMI: body mass index; hsCRP: Hypersensitive c-reactive protein; ACL: anticardiolipin, antiβ2GPI: anti-β2-glycoprotein I, LA: lupus anticoagulantm;Values in bold are statistically significant at p <0.05.Conclusion:Various factors are related to the occurrence of VTE in patients with SLE.

Abstract
AIMS Wuyiencin is a nucleoside antibiotic produced by Streptomyces albulus CK-15. The aim of this study was to determine whether wuyiencin can be used, as a suitable alternative to chemical pesticides, to protect cucumbers (Cucumis sativus L.) from powdery mildew caused by Sphaerotheca fuliginea. Further, the mechanisms underlying the control of cucumber powdery mildew by S. albulus CK-15 were preliminarily elucidated. METHODS AND RESULTS Wuyiencin solutions of different concentrations were used to treat infected cucumber plants under greenhouse conditions. The results indicated that wuyiencin could significantly reduce powdery mildew disease incidence, with a maximum prevention efficacy of 94·38%. Further, scanning electron micrographs and enzyme assays showed that wuyiencin inhibited S. fuliginea spore growth and elicited the activity of plant systemic resistance-related enzymes. Additionally, real-time quantitative reverse transcription PCR suggested that wuyiencin can activate a salicylic acid-dependent plant defence response. CONCLUSIONS Wuyiencin produced by S. albulus CK-15 possessed antifungal effects and was able to mitigate cucumber powdery mildew disease via antagonistic action. Wuyiencin also induced defence responses in the plants. SIGNIFICANCE AND IMPACT OF THE STUDY These results reinforce the biotechnological potential of wuyiencin as both an antagonistic agent and an inducer of plant systemic resistance.

Abstract
Objective: To analyze the distribution and variance of neonatal pulse oxygen saturation (SpO2) at different altitudes in China, and provide a new evidence for the screening of NCHD at high altitudes. Methods: Based on the database of National Screening Project of NCHD, the distribution of SpO2 values was described in 26 766 newborns at altitudes of 0-100 m, 600-700 m, 900-1 100 m, 1 400-1 600 m, 1 900-2 100 m, and 2 200-2 500 m. One-way analysis of variance was used to analyze the differences among SpO2 values in newborns at different altitudes. Results: The average SpO2 values of right hand in newborns at altitudes of 0-100 m, 600-700 m, 900-1 100 m, 1 400-1 600 m, 1 900-2 100 m and 2 200-2 500 m were 97.7%±1.4%, 97.1%±1.1%, 96.1%±1.3%, 96.0%±1.7%, 95.9%±1.7% and 95.5%±2.4%, respectively. And corresponding average SpO2 values of either foot were 97.7%±1.4%, 96.9%±1.1%, 96.3%±1.4%, 96.0%±1.7%, 95.6%±1.8% and 95.2%±2.7%, respectively. There were statistically significant differences in the average SpO2 values of newborns at different altitudes (right hand: F=1 248.35, P<0.001; either foot: F=1 280.45, P<0.001). The SpO2 of newborns tended to be lower with the increase of altitudes (P-trend<0.001). Conclusion: SpO2 values in newborns were negatively associated with the altitudes, which indicated that the cut-off value of screening for NCHD at sea level might not be applicable to newborns at higher altitudes. Thus, it is worthwhile to conducted studies on the normal values of SpO2 and the cut-off value of screening for NCHD in newborns at high altitudes.

Abstract
Background:Patients with autoimmune disease often require immunosuppressive medications that may increase their risk of developing severe illness from COVID-19. The importance of immunization in this population is particularly high. While the studied vaccines show efficacy in the general population, nothing is known regarding the immune response or safety profile in patients with autoimmune disease and those taking immunomodulatory medications.Objectives:To assess the safety profile and degree of adverse events from SARS-CoV-2 vaccines in patients with autoimmune and inflammatory disease.Methods:This study is part of a larger prospective observational study examining the immunogenicity and safety profile of the SARS-CoV-2 vaccine in patients with immune-mediated diseases taking immunomodulatory medications. Adults with an immune-mediated disease scheduled to receive either a Pfizer or Moderna SARS-COV-2 vaccine were enrolled in this study. Subjects participated in 3 study visits (pre-vaccine, dose 1 (D1) and dose 2 (D2)) where blood, for immunologic assays, and clinical data were collected. Assessments of adverse events (AE), including local and systemic symptoms and validated degree of AE severity were solicited within 7 days of receiving each vaccine dose.Results:To date, 70 patients with autoimmune and inflammatory disease have been enrolled. Demographic and clinical characteristics are shown in Table 1. Distribution of current immunomodulatory medications included prednisone 18.6%, conventional synthetic DMARD 55.7%, targeted synthetic DMARD 4.3%, and biologic DMARD 68.5%. Almost all participants experienced an adverse event following vaccination (D1 96%, D2 100%). Following D1 AEs were generally mild (76.5%) whereas following D2 a large portion of patients experienced AEs that were moderate (47.8%) and severe (30.5%). Injection site pain was the most common AE following both doses followed by arthralgias (D1 21.6%, D2 78.2%), fever (D1 21.6%, D2 70%) and fatigue (D1 21.6%, D2 65.2%) (Figure 1).Figure 1.Solicited Local and Systemic Adverse Events. Percentage of participants who had endorsed an adverse event within 7 days of first or second dose of SARS-CoV-2 Vaccine. ‘Other’ symptoms included chills, blurry vision, brain fog and dizziness.Conclusion:Patients with autoimmune and inflammatory disease experience a significant burden of adverse events following SARS-CoV-2 vaccination with both frequency and severity appearing greater than that of the reported results from the vaccine clinical trials. Several of the endorsed AEs such as fever, fatigue and arthralgias can also be commonly seen in rheumatologic diseases, mimicking flares. While SARS-CoV-2 immunization is crucial in patients with autoimmune diseases, this study demonstrates the importance of understanding the AEs experienced by this patient population to better inform patients of possible expected side effects of SARS-CoV-2 vaccination and further management in the future.Table 1.Demographic and Clinical Characteristics of ParticipantsParameter N (%)N=70Age [years], mean (SD)Age group48.3 ± 16.4 < 6553 (75.7) 65+17 (24.3)Gender Female48 (68.6) Male20 (38.5) Other2 (2.9)Race White47 (67.1) Asian14 (20.0) Hispanic8 (11.4) Black1 (1.4) BMI [kg/m2], mean (SD)25.0 ± 5.4Immunologic Diagnosis Rheumatoid Arthritis21 (30.0) Spondyloarthritis*21 (30.0) Systemic Lupus Erythematous8 (11.4) Connective Tissue Disease, Other‡12 (17.1) Vasculitis3 (4.2) Inflammatory Bowel Disease7 (10.0) Autoinflammatory Syndrome5 (7.1) Multiple Sclerosis2 (2.9) IgG4 Related Disease2 (2.9)Disease Duration [years], mean (SD)9.0 ± 5Medications Prednisone13 (18.6)DMARDs Hydroxychloroquine16 (22.9) Methotrexate15 (21.4) Sulfasalazine6 (8.6) Tofacitinib3 (4.3) Azathioprine2 (2.9)Biologics TNF inhibitor33 (47.1) Rituximab7 (10) Abatacept6 (8.6) IL-23 inhibitor2 (2.9)* Spondyloarthritis includes Axial Spondyloarthritis and Psoriatic Arthritis. ‡ Other Connective Tissue Disease includes scleroderma, Sjogren’s syndrome, polymyositis, and UCTD.Disclosure of Interests:Monica Yang: None declared, Patti Katz: None declared, Diana Paez: None declared, Alexander Carvidi: None declared, Mehrdad Matloubian: None declared, Mary Nakamura: None declared, Lianne S.

Abstract
TheH-Tphase diagram of Ni3V2O8is very rich and remains puzzling in a high magnetic field range. Through the state-of-the-art specific heat measurement in pulsed high field to 35 T and magnetocaloric effect measurement up to 45 T, we successfully construct the high-field phase diagram of Ni3V2O8for fields applied along thebaxis. The phase boundaries are corrected for previous results by magnetization and magneto-optical measurements. The resulting phase diagram shows that the high temperature incommensurate (HTI) phase develops well to high fields and low temperatures. In addition to the early reported C', C, low temperature incommensurate (LTI) and HTI phases, we explore a new magnetic ordered phase called HF1 in fields of 10-30 T. A multicritical point is also observed at 6 K and 8 T. Furthermore, the specific heat data reveal enhancements of the anomalies at ∼4 K, probably associated with a strong spin-lattice coupling in this frustrated multiferroic material.

Abstract
Objectives: The mortality rate of sepsis remains very high. Metabolomic techniques are playing increasingly important roles in diagnosis and treatment in critical care medicine. The purpose of our research was to use untargeted metabolomics to identify and analyze the common differential metabolites among patients with sepsis with differences in their 7-day prognosis and blood PD-1 expression and analyze their correlations with environmental factors. Methods: Plasma samples from 18 patients with sepsis were analyzed by untargeted LC-MS metabolomics. Based on the 7-day prognoses of the sepsis patients or their levels of PD-1 expression on the surface of CD4+ T cells in the blood, we divided the patients into two groups. We used a combination of multidimensional and monodimensional methods for statistical analysis. At the same time, the Spearman correlation analysis method was used to analyze the correlation between the differential metabolites and inflammatory factors. Results: In the positive and negative ionization modes, 16 and 8 differential metabolites were obtained between the 7-day death and survival groups, respectively; 5 and 8 differential metabolites were obtained between the high PD-1 and low PD-1 groups, respectively. We identified three common differential metabolites from the two groups, namely, PC (P-18:0/14:0), 2-ethyl-2-hydroxybutyric acid and glyceraldehyde. Then, we analyzed the correlations between environmental factors and the common differences in metabolites. Among the identified metabolites, 2-ethyl-2-hydroxybutyric acid was positively correlated with the levels of IL-2 and lactic acid (Lac) (P < 0.01 and P < 0.05, respectively). Conclusions: These three metabolites were identified as common differential metabolites between the 7-day prognosis groups and the PD-1 expression level groups of sepsis patients. They may be involved in regulating the expression of PD-1 on the surface of CD4+ T cells through the action of related environmental factors such as IL-2 or Lac, which in turn affects the 7-day prognosis of sepsis patients.

Abstract
OBJECTIVE To detect the expression of long non-coding ribonucleic acid (lncRNA) ASB16-AS1 in non-small cell lung cancer (NSCLC) tissues and cells, and to explore the effect of lncRNA ASB16-AS1 on the biological functions of NSCLC cells. PATIENTS AND METHODS The expression level of lncRNA ASB16-AS1 in NSCLC tissues and cells was detected via real-time fluorescence quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR). The interference sequences of lncRNA ASB16-AS1 were designed and synthesized, and its transfection efficacy was detected by qRT-PCR. After knockdown of lncRNA ASB16-AS1, the proliferation, cell cycle, and apoptosis of NSCLC cells were detected via cell counting kit-8 (CCK-8) assay, colony formation assay, and flow cytometry, respectively. Moreover, the expression changes in the Wnt/β catenin signaling pathway were detected via Western blotting. RESULTS LncRNA ASB16-AS1 was upregulated in NSCLC tissues and cells compared with that in paracarcinoma tissues and 16HBE cells. The results of CCK-8 assay and colony formation assay revealed that the silence of lncRNA ASB16-AS1 attenuated the proliferative ability in NSCLC. The results of flow cytometry manifested that the silence of lncRNA ASB16-AS1 arrested the cell cycle in G0/1 phase, and accelerated the apoptosis rate. The key proteins in the Wnt/β-catenin signaling pathway were regulated by lncRNA ASB16-AS1 in NSCLC. CONCLUSIONS LncRNA ASB16-AS1 is upregulated in NSCLC tissues and cells, which promotes proliferation and inhibits apoptosis of NSCLC cells through the Wnt/β-catenin signaling pathway.

Abstract
Objective: To investigate the diagnostic value of apparent diffusion coefficient (ADC) histogram in quantifying moderate to severe neonatal hypoxic-ischemic encephalopathy (HIE). Methods: A total of 49 children with moderate to severe HIE admitted to the Children's Hospital Affiliated to Nanjing Medical University from July 2015 to September 2018 were retrospectively analyzed. Cranial magnetic resonance imaging (MRI) data of 31 full-term neonates without neurological symptoms and signs who visited the hospital during the same period were recruited as the control group. ImgJ software was used to delineate the whole brain area at the thalamus/basal ganglia level as the area of interest, and MRIcron software was used to obtain ADC histogram parameters. The differences of ADC histogram parameters between HIE group and control group were compared. The correlation between ADC histogram parameters and neonatal neurobehavioral neurological assessment (NBNA) in HIE group was analyzed. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic efficiency of each parameter. Results: The mean value, minimum value, maximum value, mode-value, variance, heterogeneity and 10%-90% ADC values of HIE group were all greater than those of the control group(634±65,310±36,1 683±18,711±87,66 928±921,5 907±204,477±50,513±53,542±56,568±59,591±61,625±92,661±97,709±105,811±119),the differences were statistically significant(all P<0.05), while mode-count of HIE group was smaller than that of the control group(272±22 to 395±83), and the difference was statistically significant (t=2.996,P<0.05). All the above parameters with statistical differences were correlated with NBNA score, among which mode-count was negatively correlated with NBNA score(r=-0.369,P<0.05), and the rest were positively correlated(all P<0.05). The area under the ROC curve (AUC) of variance had the highest diagnostic efficiency (0.881), followed by 90% ADC value and ADC maximum value. Conclusion: ADC histogram is helpful for the diagnosis of HIE, objectively and quantitatively reflecting the diffusion information of brain, and assessing the severity of HIE.
