Abstract
BACKGROUND Benralizumab is indicated as add-on therapy in patients with uncontrolled, severe eosinophilic asthma; it has not yet been evaluated in a large Asian population with asthma in a clinical trial. OBJECTIVE To evaluate the efficacy and safety of benralizumab in patients with severe asthma in Asia. METHODS MIRACLE (NCT03186209) was a randomized, Phase 3 study in China, South Korea, and the Philippines. Patients aged 12-75 years with severe asthma receiving medium-to-high-dose inhaled corticosteroid/long-acting β2-agonists, stratified (2:1) by baseline blood eosinophil count (bEOS) (≥300/μL; <300/μL), were randomized (1:1) to benralizumab 30 mg or placebo. Endpoints included annual asthma exacerbation rate (AAER; primary endpoint), change from baseline at Week 48 in pre-bronchodilator (BD) forced expiratory volume in 1 second (pre-BD FEV1) and total asthma symptom score (TASS). Safety was evaluated ≤ Week 56. RESULTS Of 695 patients randomized, 473 had baseline bEOS ≥300/μL (benralizumab n = 236; placebo n = 237). In this population, benralizumab significantly reduced AAER by 74% (rate ratio 0.26 [95% CI 0.19, 0.36], p < 0.0001) and significantly improved pre-BD FEV1 (least squares difference [LSD] 0.25 L [95% CI 0.17, 0.34], p < 0.0001) and TASS (LSD -0.25 [-0.45, -0.05], p = 0.0126) versus placebo. In patients with baseline bEOS <300/μL, there were numerical improvements in AAER, pre-BD FEV1, and TASS with benralizumab versus placebo. The frequency of adverse events was similar for benralizumab (76%) and placebo (80%) in the overall population. CONCLUSIONS MIRACLE data reinforces the efficacy and safety of benralizumab for severe eosinophilic asthma in an Asian population, consistent with the global Phase 3 results.

Abstract
Histone demethylase (HDM) play crucial roles in regulating plant growth and environmental adaptation. In this study, the HDM gene family in melon was identified by bioinformatics methods and the expression patterns of the CmHDM family members in different melon tissues were analyzed using transcriptome data. The results showed that 20 CmHDM genes were identified in the melon genome, which were unevenly distributed across each chromosome. These members fall into two major categories: LSD1 and JmjC. The JmjC group could be further divided into five subgroups with different numbers. The results of collinearity analysis of intraspecific and interspecific relationships showed that there were only one pair of segmental duplication in melon HDM genes, and more collinearity in genetic relationship of HDM genes between melon and tomato. The numbers of conserved domains, exons and introns in each member vary and various cis-acting elements responding to hormones and environmental signals existed in the respective promoter regions. Expression analysis showed that the respective gene members were expressed at different levels in male flowers, female flowers, roots, stems, leaves, ovary, and mature fruits of melon. These results will contribute to the understanding on the potential functions of the HDM genes and their potential functions in regulating melon growth and environmental adaptation.

Abstract
OBJECTIVES This study aims to investigate the high-risk factors for osteonecrosis of the femoral head (ONFH) after internal fixation with multiple cannulated compression screws for adult femoral neck fractures and to construct a prediction model. PATIENTS AND METHODS Between from January 2012 and December 2020, a total of 268 patients (138 males, 130 females; mean age: 53±10 years; range, 23 to 70 years) with ONFH who had complete follow-up data were included. Closed reduction in combination with open reduction were performed. All patients received internal fixation with multiple cannulated compression screws and were assigned to ONFH and non-ONFH groups. Logistic regression model was utilized to identify independent risk factors for postoperative ONFH, followed by constructing a nomogram prediction model. The predictive ability of the model was evaluated by receiver operating characteristic curve, Hosmer-Lemeshow test, and calibration curve. RESULTS Multivariate analysis revealed that older age (odds ratio [OR]: 2.307, 95% confidence interval [CI]: 1.295-4.108], Charlson Comorbidity Index (CCI) ≥2 (OR: 2.214, 95% CI: 1.035-4.739), fracture displacement (OR: 2.426, 95% CI: 1.122-5.247), unsatisfactory reduction (OR: 2.629, 95% CI: 1.275-5.423), postoperative removal of internal fixation implant (OR: 2.200, 95% CI: 1.051-4.604) were independent risk factors for postoperative ONFH (p<0.05). The nomogram prediction model constructed based on these clinical characteristics showed high predictive value (AUC=0.807) and consistency (p>0.05). CONCLUSION Age, comorbidity index, fracture type, reduction quality and postoperative removal of internal fixation implant are of utmost importance for postoperative ONFH in patients with femoral neck fractures. The established nomogram prediction model can accurately predict the occurrence of postoperative ONFH.

Abstract
1. Fusarium tritici widely exists in a variety of grain feeds. The T-2 toxin is the main hazardous component produced by Fusarium tritici, making a serious hazard to poultry industry. Morin, belonging to the flavonoid family, can be extracted from mulberry plants and possesses anticancer, antioxidant and anti-inflammatory compounds, but whether morin protects chicks with T-2 toxin poisoning remains unclear. This experiment firstly established a chick model of T-2 toxin poisoning and then investigated the protective effects and mechanism of morin against T-2 toxin in chicks.2. The function of liver and kidney was measured by corresponding alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine (Cre) and uric acid (UA) kits. Histopathological changes were observed by haematoxylin-eosin staining. The status of oxidative stress was measured by MDA, SOD, CAT, GSH and GSH-PX kits. The mRNA levels of TNF-α, COX-2, IL-1β, IL-6, caspase-1, caspase-3 and caspase-11 were measured by quantitative real-time PCR. Heterophil extracellular trap (HET) release was analysed by immunofluorescence and fluorescence microplate.3. The model with T-2 toxin poisoning in chicks was successfully established. Morin significantly decreased T-2 toxin-induced ALT, AST, ALP, BUN, Cre and UA, and improved T-2 toxin-induced liver cell rupture, liver cord disorder and kidney interstitial oedema. Oxidative stress analysis showed that morin ameliorated T-2 toxin-induced damage by reducing malondialdehyde (MDA), increasing superoxide dismutase (SOD), catalase (CAT), glutathione (GSH) and glutathione peroxidase (GSH-PX). The qRT-PCR analysis showed that morin reduced T-2 toxin-induced mRNA expressions of TNF-α, COX-2, IL-1β, IL-6, caspase-1, caspase-3 and caspase-11. Moreover, morin significantly reduced the release of T-2 toxin-induced HET in vitro and in vivo.4. Morin can protect chicks from T-2 toxin poisoning by decreasing HETs, oxidative stress and inflammatory responses, which make it a useful compound against T-2 toxin poisoning in poultry feed.

Abstract
A cross-cultural comparison is made of delay discounting in samples of participants from Chile and China. Comparisons are made based on previous literature that suggests that individuals from an Asian culture should be willing to postpone delayed rewards more than are individuals from a Latin American culture. To test the cross-cultural validity of a hyperbolic discounting model, the model was fitted to both data sets. Additionally, a self-enhancement measure was evaluated as a potential mediator between culture of origin and delay discounting. Seventy-eight college students from China and 120 college students from Chile, with similar demographic backgrounds, discounted hypothetical monetary outcomes using an adjusting-amount titration procedure. Additionally, participants completed a self-enhancement measure. Age, academic major, gender, and grade point average were controlled. Chilean participants discounted much more steeply than Chinese nationals did. No support was obtained for the mediation of self-enhancement between culture of origin and degree of delay discounting. In both samples, delay discounting was better described by a hyperboloid than an exponential function, the only exception being the $10,000 condition in which the medians for Chilean participants' present subjective value were equally well explained by a hyperboloid and an exponential function.

Abstract
Lithium-sulfur batteries (LSBs) are some of the most promising energy storage systems to break the ceiling of Li-ion batteries. However, the notorious shuttle effect and slow redox kinetics give rise to low sulfur utilization and discharge capacity, poor rate performance, and fast capacity decay. It is proved that the reasonable design of the electrocatalyst is one of the important ways to improve the electrochemical performance of LSBs. Here, a core-shell structure with gradient adsorption capacity for reactants and sulfur products was designed. The Ni nanoparticles core coated with graphite carbon shell was prepared by one-step pyrolysis of Ni-MOF precursors. The design takes advantage of the principle that the adsorption capacity decreases from the core to the shell, and the Ni core with strong adsorption capacity is easy to attract and capture soluble lithium polysulfide (LiPS) during the discharge/charging process. This trapping mechanism prevents the diffusion of LiPSs to the outer shell and effectively inhibits the shuttle effect. In addition, the Ni nanoparticles within the porous carbon, as the active center, expose most of the inherent active sites to the surface area, thus achieving a rapid transformation of LiPSs, significantly reducing the reaction polarization, and improving the cyclic stability and reaction kinetics of LSB. Therefore, the S/Ni@PC composites exhibited excellent cycle stability (a capacity of 417.4 mA h g-1 for 500 cycles at 1C with a fading rate of 0.11%) and outstanding rate performance (1014.6 mA h g-1 at 2C). This study provides a promising design solution of Ni nanoparticles embedded in porous carbon for high-performance, safe and reliable LSB.

Abstract
The Taiyuan Xishan Ecological Restoration Zone is located in the west of Taiyuan City and belongs to the Xishan Coalfield. Due to the resource development activity of coal mining, which is caused by coal gangue accumulation, surface vegetation degradation, bare surfaces, and other phenomena, it is most common in this area. These have an impact on the surface ecology; however, after ecological restoration, the surface ecology has been greatly improved. There are many extraction models of vegetation coverage based on pixel dichotomology combined with multispectral vegetation index, but we believe that the combination of visible light vegetation index to construct models is relatively unexplored. The main problem of how to use the RGB image data in order to quickly and accurately extract vegetation coverage information is still under investigation and needs researchers' attention. In this paper, through selecting the vegetation coverage as the evaluation index of ecological restoration effect, a new RGB vegetation coverage CIVE calculation model is innovatively proposed to solve the above problem, and on the basis of this model, the vegetation cover change analysis is carried out in the Xishan ecological restoration area of Taiyuan. According to the analysis of vegetation coverage change, relevant paper data, and the characteristics of multiple historical remote sensing images, the ecological restoration area of Taiyuan Xishan is divided into six typical areas. Through empirical evaluation, we summarize and analyze these six typical areas, which can provide typical demonstration roles for other ecological restoration areas. Our findings suggest that the proposed CIVE model realizes the extraction of vegetation cover information and long-term series dynamic monitoring of vegetation coverage.

Abstract
Current wound healing models generally employ full-thickness or irregular split wounds. Consequently, assessing the type of healing at varying wound depths and determining the deepest level at which wounds can regenerate has been a challenge. We describe a wound model that allows assessment of the healing process over a continuous gradient of wound depth, from epidermal to full-thickness dermal loss. Further, we investigate whether green fluorescent protein-labeled bone marrow mesenchymal stem cells (BM-MSCs/GFP) transplantation could regenerate deeper wounds that might otherwise lead to scar formation. A wound gradient was created on the back of 120 Sprague Dawley rats, which were randomized into the BM-MSCs/GFP and control group. These were further subdivided into 6 groups where terminal biopsies of the healing wounds were taken at days 1, 3, 5, 7, 14, and 21 post-operatively. At each observed time point, the experimental animals were anesthetized and photographed, and depending on the group, the animals euthanized and skin taken for rapid freezing, haemotoxylin and eosin staining, and vascular endothelial growth factor (VEGF) immunohistochemistry. We found the deepest layer to regenerate in the control group was at the level of the infundibulum apex, while in the BM-MSCs/GFP group this was deeper, at the opening site of sebaceous duct at hair follicle in which had the appearance of normal skin and less wound contraction than the control group (P value less than .05). The expression of VEGF in BM-MSCs/GFP group was higher than that in control group (P value less than .05). The number of vessels increased from 2.5 ± 0.2/phf of control group to 5.0 ± 0.3/phf of BM-MSCs/GFP (P value less than .05). The progressively deepening wound model we described can identify the type of wound repair at increasing depths. Further, topical transplantation of BM-MSCs/GFP significantly improved regeneration of deeper wounds from infundibulum apex (maximum depth of control group regeneration) to the opening site of sebaceous duct at hair follicle level.

Abstract
Objective The aims of this study were to characterize the evolution of routine blood values within the first 10 days of illness and coronary artery outcome in infants < 8 months with Kawasaki disease (KD) and to identify risk factors for coronary artery aneurysm (CAA). Methods Laboratory data, clinical features and coronary artery outcomes from 78 infants < 8 months old and 86 patients between 8 months and 7 years old were retrospectively analyzed. Logistic regression analysis was conducted to evaluate the potential risk factors for CAA. Results Infants < 8 months old were more likely to present with incomplete KD (37.2% vs 4.7%, P < 0.001), erythema and induration at the BCG inoculation site (24.4% vs 3.5%, P < 0.001) and CAA (47.4% vs 15.1%, P < 0.001) even with timely diagnosis and treatment with intravenous immunoglobulin (IVIG) compared with patients ≥8 months old. Clinical feature related to diagnostic criteria for KD including bilateral conjunctival injection, oral changes, unilateral cervical lymphadenopathy and extremity changes were less common in the younger group. During the acute phase, the percentage neutrophils and neutrophil to lymphocyte ratio [NLR] peaked on median illness day 3, followed by white blood cell (WBC) and CRP on median illness day 4, hemoglobin on median illness day 7 and platelet count on median illness day 9. CAA occurred on median illness day 6 and regressed on median illness day 28. Multivariate logistic regression analysis revealed that the peak percentage neutrophils (odds ratio [OR] per 0.1: 1.597, 95% confidence interval [CI]: 1.041–2.452, P = 0.032) and the peak platelet count (OR per 10 × 109/L: 1.029, 95% CI: 1.004–1.055, P = 0.024) were independent risk factors for CAA. Hemoglobin on the 5th day was associated with persistent CAA at 1 year after KD onset. Conclusion Factors associated with CAA include a high peak percentage neutrophils, increased peak platelet count, and reduced hemoglobin within 4–6 days during the acute phase of KD. Therefore, this population should receive primary therapy with IVIG and adjunctive anti-inflammatory medications.

Abstract
Non-small cell lung cancer (NSCLC), a commonly diagnosed lung cancer, is characterized by a high incidence of metastatic spread to the brain, which adversely impacts prognosis. The present study aimed to assess the value of combined dynamic contrast-enhanced MRI (DCE-MRI) and diffusion-weighted imaging (DWI) in predicting the treatment outcomes of whole-brain radiotherapy (WBRT) and gefitinib in brain metastases from non-small cell lung cancer (NSCLC) from the perspectives of response rate and short- and long-term efficacy. These results suggested that the indicators measured by DCE-MRI combined with DWI can be used as key imaging-derived markers that predicted the efficacy of WBRT combined with gefitinib in NSCLC patients with brain metastases. Specifically, patients with higher ΔADCmid and ΔADCpost values showed better treatment outcomes. ROC curve analysis indicated ADCpost, ΔADCpost, ΔADCpost (%), and tumor regression rate as the best predictors of efficacy of WBRT combined with gefitinib in these patients. The short-term and long-term effects noted were also significant. Taken together, the findings of this study reveal that tumor regression rate, ADCpost, ΔADCpost, and ΔADCpost (%) can be used as important imaging indicators that predict the therapeutic effect of WBRT combined with gefitinib in NSCLC patients with brain metastases.

Abstract
Background and Objectives Osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) plays a critical role in the success of lumbar spinal fusion with autogenous bone graft. This study aims to explore the role and specific mechanism of miR-34c-5p in osteogenic differentiation of BMSCs. Methods and Results Rabbit model of lumbar fusion was established by surgery. The osteogenic differentiation dataset of mesenchymal stem cells was obtained from the Gene Expression Omnibus (GEO) database, and differentially expressed miRNAs were analyzed using R language (limma package). The expressions of miR-34c-5p, miR-199a-5p, miR-324-5p, miR-361-5p, RUNX2, OCN and Bcl-2 were determined by qRT-PCR and Western blot. ELISA, Alizarin red staining and CCK-8 were used to detect the ALP content, calcium deposition and proliferation of BMSCs. The targeted binding sites between miR-34c-5p and Bcl-2 were predicted by the Target database and verified using dual-luciferase reporter assay. MiR-34c-5p expression was higher in rabbit lumbar fusion model and differentiated BMSCs than normal rabbit or BMSCs. The content of ALP and the deposition of calcium increased with the osteogenic differentiation of BMSCs. Upregulation of miR-34c-5p reduced cell proliferation and promoted ALP content, calcium deposition, RUNX2 and OCN expression compared with the control group. The effects of miR-34c-5p inhibitor were the opposite. In addition, miR-34c-5p negatively correlated with Bcl-2. Upregulation of Bcl-2 reversed the effects of miR-34c-5p on ALP content, calcium deposition, and the expressions of RUNX2 and OCN. Conclusions miR-34c-5p could promote osteogenic differentiation and suppress proliferation of BMSCs by inhibiting Bcl-2.

Abstract
The aging of the immune system is not only an inevitable result but also an important cause of physical aging. The aging of the immune system is rooted in the aging of hematopoietic cells (HSCs), which manifests as decreasing functionality of the adaptive immune system and the innate immune system. C57BL/6 mice of different ages were collected in this study to better understand the changes in the structures of the innate and adaptive immune systems in individuals of different ages and the distribution and changes in immune cells with stem cell properties. The immune cells of the innate and adaptive immune systems, including DCs, monocytes, macrophages, CD4+ T lymphocytes, CD8+ T lymphocytes, and B lymphocytes, were assessed, and the proportions of cells with stem cell properties among these immune cell populations were also tested. Overall, immune cells in the peripheral blood, spleen, and bone marrow of mice exhibit certain regular properties with increasing age. The trend of changes in immune cells in different immune organs differs with age. The changes in lymphocytes in the peripheral blood are more sensitive. Their proportions increase slowly with age and then decrease rapidly to a very low level (less than 5%) after a certain point (9 or 13 months old). Nine to 13 months of age is the most critical time point for assessing changes in the immune system of mice and the most critical time point for detecting changes in the proportion of stem cells. After 13 months of age, the balance and stability of stem cells in mice are disrupted, and animals begin to age rapidly. The ratio of Ly6A to E+CD117+ cells in the peripheral blood, particularly lymphocytes involved in adaptive immunity, represents a specific marker for predicting immune senescence and body senescence.

Abstract
The large-scale and controllable synthesis of novel N-doped three-dimensional (3D) carbon nanocage-decorated carbon skeleton sponges (Co-NCMS) is introduced. These Co-NCMS were highly active and durable non-noble metal catalysts for the oxygen reduction reaction (ORR). This hybrid electrocatalyst showed high ORR activity with a diffusion-limiting current of 5.237 mA·cm-2 in 0.1 M KOH solution through the highly efficient 4e- pathway, which was superior to that of the Pt/C catalyst (4.99 mA·cm-2), and the ORR Tafel slope is ca. 67.7 mV·dec-1 at a high potential region, close to that of Pt/C. Furthermore, Co-NCMS exhibited good ORR activity in acidic media with an onset potential comparable to that of the Pt/C catalyst. Most importantly, the prepared catalyst showed much higher stability and better methanol tolerance in both alkaline and acidic solutions. The power density obtained in a proton exchange membrane fuel cell was as high as 0.37 W·cm-2 at 0.19 V compared with 0.45 W·cm-2 at 0.56 V for the Pt/C catalyst. In Co-NCMS, the N-doped carbon nanocages facilitated the diffusion of the reactant, maximizing the exposure of active sites on the surface and protecting the active metallic core from oxidation. This made Co-NCMS one of the best non-noble metal catalysts and potentially offers an alternative approach for the efficient utilization of active transition metals in electrocatalyst applications.

Abstract
BACKGROUND In colon cancer, tumor deposits (TD) are considered in assigning prognosis and staging only in the absence of lymph node metastasis (i.e. stage III pN1c tumors). We aimed to evaluate the prognostic value of the presence and the number of TD in patients with stage III, node-positive colon cancer. PATIENTS AND METHODS All participants from the CALGB/SWOG 80702 phase III trial were included in this post hoc analysis. Pathology reports were reviewed for the presence and the number of TD, lymphovascular and perineural invasion. Associations with disease-free survival (DFS) and overall survival (OS) were evaluated by multivariable Cox models adjusting for sex, treatment arm, T-stage, N-stage, lymphovascular invasion, perineural invasion and lymph node ratio. RESULTS Overall, 2028 patients were included with 524 (26%) TD-positive and 1504 (74%) TD-negative tumors. Of the TD-positive patients, 80 (15.4%) were node negative (i.e. pN1c), 239 (46.1%) were pN1a/b (<4 positive lymph nodes) and 200 (38.5%) were pN2 (≥4 positive lymph nodes). The presence of TD was associated with poorer DFS [adjusted hazard ratio (aHR) = 1.63, 95% CI 1.33-1.98] and OS (aHR = 1.59, 95% CI 1.24-2.04). The negative effect of TD was observed for both pN1a/b and pN2 groups. Among TD-positive patients, the number of TD had a linear negative effect on DFS and OS. Combining TD and the number of lymph node metastases, 104 of 1470 (7.1%) pN1 patients were re-staged as pN2, with worse outcomes than patients confirmed as pN1 (3-year DFS rate: 65.4% versus 80.5%, P = 0.0003; 5-year OS rate: 87.9% versus 69.1%, P = <0.0001). DFS was not different between patients re-staged as pN2 and those initially staged as pN2 (3-year DFS rate: 65.4% versus 62.3%, P = 0.4895). CONCLUSION Combining the number of TD and the number of lymph node metastases improved the prognostication accuracy of tumor-node-metastasis (TNM) staging.

Abstract
BACKGROUND Myocardial ischemia/reperfusion injury (IRI) is a common perioperative complication of heart and great vessels surgery, aggravating the original myocardial damage and seriously affecting the postoperative recovery of cardiac function. The aim of this study was to reveal the functional effects and potential mechanisms of notoginsenoside R1 (NG-R1) in myocardial cells injured by hypoxia-reoxygenation (H/R). METHODS The rat cardiomyocyte line H9c2 was subjected to H/R with or without NG-R1 treatment. The levels of miR-132 and HBEGF in the cell were altered by microRNA or short-hairpin RNA transfection. Cell viability, apoptosis, lactate dehydrogenase (LDH) and malondialdehyde (MDA) were monitored. Dual luciferin was used to detect the relationship between miR-132 and HBEGF. RESULTS NG-R1 (20 μM) had no impact on H9c2 cells, but cell viability was significantly reduced at 80 μM. NG-R1 (20 μM) protected H9c2 cells against H/R-induced cell damage, accompanied by increased cell viability, reduced cell apoptosis, and downregulation of LDH and MDA. Furthermore, the level of miR-132 was decreased in response to H/R exposure but then increased after NG-R1 treatment. When miR-132 was overexpressed, H/R-induced cell damage could be recovered. Downregulation of miR-132 limited the protective effect of NG-R1 on H/R damage. We also found that HBEGF was a direct target of miR-132. The expression of HBEGF was increased upon H/R damage, and this increase was reversed after NG-R1 treatment. CONCLUSIONS This study demonstrated that NG-R1 markedly protected H9c2 cells against H/R-induced damage via upregulation of miR-132 and downregulation of its target protein HBEGF.

Abstract
OBJECTIVE To explore whether plasmacytoma variant translocation 1 (PVT1) could regulate glioblastoma multiforme (GBM) progression via microRNA-1301-3p (miR-1301-3p) and transmembrane BAX inhibitor motif containing 6 (TMBIM6) axis. MATERIALS AND METHODS Expression patterns of PVT1 and RMBIM6 in GBM patients were analyzed using GEPIA, an online gene expression analysis tool. Levels of PVT1 in GBM cells and normal cells were analyzed with quantitative real-time PCR method. Cell Counting Kit-8 (CCK-8), transwell invasion assay, and flow cytometry assay were applied to detect cell viability and apoptosis. Connections of PVT1 or TMBIM6 with miR-1301-3p were validated with bioinformatic tool and luciferase activity reporter assay. RESULTS PVT1 was significantly expressed in GBM tissues and cells. PVT1 promotes GBM cell proliferation and invasion but inhibits apoptosis in vitro. TMBIM6 was significantly expressed in GBM tissues. The knockdown of TMBIM6 reversed the stimulation effects of PVT1 on GBM cell malignancy behaviors with miR-1301-3p as a bridge. CONCLUSIONS Collectively, we showed PVT1 elevated TMBIM6 expression mediated by miR-1301-3p and thus to promote GBM progression.

Abstract
Acute myocardial infarction (AMI) is a major cause of death in a patient with systemic lupus erythematosus (SLE). Due to their chronic inflammatory state, patient with SLE has an increased risk of developing coronary artery disease. We report a case of a middle-aged woman with an acute myocardial infarction (AMI) caused by a right coronary artery (RCA) stenosis complicated with severe coronary artery spasm. Our patient has a history of long-standing SLE. Clinical expression of coronary artery disease (CAD) in SLE is the result of different pathophysiologic mechanism. From this case, we raise the importance of the clinician to be aware of the diverse pathophysiologic pathways involving a coronary artery in a patient with SLE.

Abstract
Bupivacaine is frequently used for regional anesthesia and postoperative analgesia. However, an inadvertent intravenous injection can cause severe cardiotoxicity, manifesting as arrhythmia, hypotension, and even cardiac asystole. The mechanism of bupivacaine-mediated cardiotoxicity remains unclear. SK2 knockout mice (SK) and wild-type mice (WT) were divided into four groups, with 12 mice per group. We determined the difference in bupivacaine cardiotoxicity between SK2 knockout and WT mice by measuring the time to the first arrhythmia (Tarrhythmia) and the time to asystole (Tasystole). Secondary indicators of cardiotoxicity were the time from the beginning of bupivacaine infusion to 20% prolongation of the QT interval (TQT) and the time to 20% widening of the QRS complex (TQRS). Tarrhythmia and Tasystole were significantly longer in the SK-bupi group than in the WT-bupi group (both P < 0.05). TQT and TQRS were longer in the SK-bupi group than in the WT-bupi group (all P < 0.05). The time to 25%, 50%, and 75% reduction in HR in the SK-bupi group was significantly longer than in the WT-bupi group (all P < 0.05). Knocking out the SK2 channel can reduce bupivacaine-induced cardiotoxicity in the mouse.

Abstract
OBJECTIVE To investigate the expression of micro ribonucleic acid (miR)-219-5p in prostate cancer (PCa), its influences on the biological functions of PCa, and its mechanism. PATIENTS AND METHODS The expression differences of miR-219-5p and high mobility group protein A2 (HMGA2) in 30 pairs of PCa tissues and para-carcinoma tissues were detected via quantitative Real Time-Polymerase Chain Reaction (qRT-PCR), and the difference in miR-219-5p expression in PCa cell lines and normal prostatic epithelial cells was also determined via qRT-PCR. The human PC-3 cells were divided into negative control group and miR-219-5p overexpression group. Methyl thiazolyl tetrazolium (MTT) and colony formation assays were adopted to detect the cell proliferative ability, and flow cytometry was applied to determine the cell apoptosis. The expression of apoptosis-related proteins was measured via Western blotting, and the invasive and migratory abilities of the cells were examined through wound-healing and transwell assays. Bioinformatics prediction software and luciferase reporter assay were employed to verify the targets that might be controlled by miR-219-5p. Rescue experiment was conducted to clarify whether the inhibitory effects of miR-219-5p on the growth and metastasis of PC-3 cells depend on the inhibition of HMGA2. RESULTS It was shown in qRT-PCR results that the expression level of miR-219-5p was downregulated remarkably in PCa tissues and cell lines, but overexpressed miR-219-5p could repress the proliferation and promote the apoptosis of PC-3 cells notably. The results of wound-healing and transwell assays indicated that overexpressed miR-219-5p was able to suppress the invasion and metastasis of PC-3 cells. According to Western blotting results, overexpressed miR-219-5p could up-regulate the expressions of pro-apoptotic proteins [Bax, cleaved-caspase-3 and cleaved-poly-ADP-ribose-polymerase (PARP)] and reverse the epithelial-mesenchymal transition (EMT) of PCa cells. It was predicted via the bioinformatics software that HMGA2 gene might be a target gene of miR-219-5p. The Dual-Luciferase reporter assay confirmed that there was a direct regulatory relationship between miR-219-5p and HMGA2. The rescue experiment manifested that overexpressed HMGA2 could reverse the inhibition of miR-219-5p on the growth and metastasis of PC-3 cells. CONCLUSIONS MiR-219-5p suppresses the growth and metastasis abilities of prostate cancer cells by directly repressing the expression of HMGA2.

Abstract
Apelin has been reported to regulate mitochondrial function in myocardial ischemia-reperfusion injury and cerebral ischemia-reperfusion injury. However, the role of apelin-13 in lung ischemia-reperfusion injury (LIRI) remains unclear. This study established an experimental rat model to evaluate the underlying mechanisms of apelin-13 on LIRI. Twenty-four rats were randomly divided to sham operation group (group SM), ischemia/reperfusion group (group IR), and apelin-13 treatment group (group APL). The effects of apelin-13 on LIRI were determined histologically using H&E staining, while the wet/dry weight ratio was used to assess lung edema caused by LIRI. Inflammatory cytokines were also detected in Bronchoalveolar lavage (BAL) fluid by ELISA. The protein expression of UCP2 and the morphological changes of mitochondria were determined by western blotting and electromicroscopy, respectively. The results demonstrated the structural damage of lung tissues and lung edema in group IR. An increased level of inflammatory cytokines including IL-1β, IL-6 and TNF-α was observed in rats with LIRI using ELISA. After that, oxidative stress and morphological damage of mitochondria were also shown in group IR. Yet, the application of apelin-13 reversed all these deleterious effects in group APL. The protective effects of apelin-13 were indicated by decreased reactive oxygen species (ROS) and elevated UCP2 expression levels in rats. In conclusion, this study revealed that apelin-13 had protective effects against LIRI via attenuating lung edema, the production of inflammatory cytokines, oxidative stress and mitochondrial dysfunction.

Abstract
Bupivacaine is frequently used for conducting regional anesthesia. When accidentally injected or excessively absorbed into circulation, bupivacaine can induce severe arrhythmia and potentially lead to cardiac arrest. The specific mechanisms underlying this cardiotoxicity, however, remain to be clarified. We transfected HEK-293 cells to express the small conductance calcium-activated potassium type-2 channel (SK2), and used a whole-cell patch clamp method in order to explore how bupivacaine affected these channels. We subsequently used SK2 knockout mice to explore the relevance of SK2 channels in bupivacaine-induced cardiotoxicity in isolating mouse hearts, mounting them on a Langendorff apparatus, and perfusing them with bupivacaine. Using this system, arrhythmia, asystole, and cardiac functions were monitored. We observed dose-dependent inhibition of SK2 channels by bupivacaine: half-maximal inhibitory concentration (IC50) value = 18.6 μM (95% CI 10.8-32.1). When SK2 knockout (SK2 -/-) or wild-type (WT) mice were perfused with Krebs-Henseleit buffer (KHB), we did not observe any instances of arrhythmia. When SK2 -/- mice or WT were perfused with KHB containing bupivacaine (40 μM), the time to arrhythmia (Tarrhythmia) and time to asystole (Tasystole) were both significantly longer in SK2 -/- mice relative to WT mice (P < 0.001). Similarly, SK2 -/- mice exhibited a significantly longer time to 25%, 50%, and 75% reductions in heart rate (HR) and rate-pressure product (RPP) relative to WT mice following bupivacaine perfusion (P < 0.001). These results reveal that bupivacaine was able to mediate a dose-dependent inhibition of SK2 channels in HEK-293 cells, and deletion of SK2 channels can delay bupivacaine-induced cardiotoxicity in isolated mouse hearts.

Abstract
BACKGROUND There is no identified level of FDG uptake in cardiac sarcoidosis (CS) associated with increased risk of arrhythmias, conduction disease, heart failure, or death. We aim to utilize standardized uptake value (SUV) quantitation and localization to identify patients at increased risk of cardiac events. METHODS AND RESULTS F18-FDG PET/CT with MPI was used in CS diagnosis (N = 67). Mean and max SUV were measured and grouped as basal, mid, and apical disease. Post-scan ventricular tachycardia, AICD placement, complete heart block, pacemaker placement, atrial fibrillation, heart failure, and cardiac-related hospital admissions were recorded (mean follow up 2.98 ± 2 years). Poisson regression analysis revealed that max SUV, mean SUV, as well as mean basal SUV, and LVEF were significantly associated with total cardiac events. Max SUV odds ratio (OR) = 1.068 (95% CI 1.024-1.114, P = 0.002), mean SUV OR = 1.059 (95% CI 1.008-1.113, P = 0.023), mean SUV OR = 1.061 (95% CI 1.012-1.112, P = 0.014), scan LVEF OR = 0.731 (95% CI 0.664-0.805, P < 0.001). CONCLUSIONS SUV at time of CS diagnosis has significant associations with future cardiac events. Patients with higher SUV, particularly in basal segments, are at increased risk of events. Further studies are needed to identify treatment methods utilizing risk stratification of CS.

Abstract
OBJECTIVE To investigate the effects and mechanism of metformin (Met) combined the interleukin-12 (IL-12) on inhibiting hepatoma HepG2 cell proliferation via in vitro and in vivo assays. MATERIALS AND METHODS MTT assay was used to detect inhibitory effects of Met, IL-12 alone or combination on HepG2 cells proliferation. Half inhibitory concentration (IC50) and combination index (CI) were also calculated. Anti-tumor effects of combination or monotherapy on the HepG2-bearing mice were investigated and protein expression levels of apoptosis, as well as the Akt/mTOR/STAT3 signaling pathway-related factors were detected by Western blot. RESULTS MTT results showed that the inhibitory effect of Met combined with IL-12 on HepG2 cell proliferation was significantly enhanced (both p<0.01) compared with monomer therapy group with a significant synergistic effect (CI<1). The apoptosis rate of HepG2 cells treated with Met combined with IL-12 were 88.12±7.15% and significantly higher than the others (all p<0.01). Moreover, combination treatment significantly suppressed hepatoma growth and increased the survival rate of HepG2-bearing mice without evident body weight loss. Western blot analysis showed that Met combined with IL-12 significantly increased the expression of autophagy-related marker proteins, downregulated the protein expression levels of Bcl-2, p-Akt, p-mTOR, p-STAT3, upregulated the expression level of BAX in both HepG2 cells and tumor tissues. CONCLUSIONS Met combined with IL-12 exhibited a synergistic antitumor effect on hepatoma HepG2 cells, and the mechanism may be related to its common inhibition of Akt/mTOR/STAT3 signaling pathway and increase of autophagy in HepG2-bearing mice.

Abstract
Abstract
Background
Prolonged monitoring of cardiac rhythm has been used in patients with symptomatic arrhythmias and to assess for atrial fibrillation (AF) after cryptogenic stroke, but not in the general population and especially in older adults.
Purpose
To evaluate the frequency of arrhythmias in a community-based cohort of older adults through 14-days continuous cardiac monitoring using a patch-based device.
Methods
Cardiac rhythm was analyzed in 533 participants free of AF and congestive heart failure (CHF) from the tri-ethnic (white, black, Hispanic) Subclinical Atrial Fibrillation and Risk of Ischemic Stroke (SAFARIS) study. AF, supraventricular tachycardia (SVT, defined as 4 beats or more), premature atrial (PACs) and ventricular (PVCs) contractions, ventricular tachycardia (VT, defined as 4 beats or more), sinus pauses (SP) and atrio-ventricular blocks (AVB) were analyzed. Gender, age and race-ethnic differences were examined.
Results
Mean age was 77.2±6.8 years (198 men, 335 women). Recording duration was over 10 days in 91%, and over 13 days in 84%. AF was present in 10 participants (1.9%), atrial flutter in 1 (0.2%). Other arrhythmias are reported in the Table. SP (1.9%) and high-degree AVB (Mobitz II: 0.6%; 3rd degree: 0.9%) were rare. No significant race-ethnic differences were observed.
Conclusion
In older adults without history of stroke or CHF, prolonged rhythm monitoring revealed moderate frequency of AF, but higher than expected frequencies of AF-predisposing conditions such as SVT and frequent PACs. VT episodes were relatively frequent, whereas SP and AVB were less frequent than commonly believed. Most arrhythmias were more frequent in the oldest; ventricular arrhythmias were more common in men than in women.

Abstract
The Kitaev model on the honeycomb lattice has been receiving substantial attention due to the discovery of quantum spin liquid state associated with this model. Consequently, its classical partners such as the Kitaev-Heisenberg (KH) model and associated phase transitions become concerned. Specifically, an intermediate Kosterlitz-Thouless (KT) phase engaged in the transition from the high-temperature (T) disordered state to the low-T sixfold degenerate state is predicted in the isotropic KH model [Phys. Rev. Lett. 109, 187201 (2012)10.1103/PhysRevLett.109.187201], but so far no sufficient experimental proof has been reported. In this work, we consider an essential extension of this KH model on the honeycomb lattice by including the Kitaev exchange anisotropy that is non-negligible in realistic materials. The associated phase transitions are thus investigated using the Monte Carlo simulations. It is found that such an anisotropy will result in a degradation of the sixfold degeneracy of the ground state in the isotropic KH model down to the fourfold or twofold degenerate ground state, and the finite-T phase transitions will also be modified remarkably. Interestingly, the intermediate KT phase can be suppressed by this Kitaev exchange anisotropy. This work thus provides a more realistic description of the physics ingredient with the KH model and presents a possible explanation on absence of the intermediate phase in real materials where the Kitaev exchange anisotropy can be more or less available.

Abstract
BACKGROUND AND PURPOSE Previous studies have shown that diffusion tensor imaging suggests a diffuse loss of white matter integrity in people with white matter hyperintensities or lacunes. The purpose of this study was to investigate whether the presence of cerebral microbleeds and their distribution are related to the integrity of white matter microstructures. MATERIALS AND METHODS The study comprised 982 participants who underwent brain MR imaging to determine microbleed status. The cross-sectional relation between microbleeds and the microstructural integrity of the white matter was assessed by 2 statistical methods: a multilinear regression model based on the average DTI parameters of normal-appearing white matter and Tract-Based Spatial Statistics analysis, a tract-based voxelwise analysis. Fiber tractography was used to spatially describe the microstructural abnormalities along WM tracts containing a cerebral microbleed. RESULTS The presence of cerebral microbleeds was associated with lower mean fractional anisotropy and higher mean diffusivity, axial diffusivity, and radial diffusivity, and the association remained when cardiovascular risk factors and cerebral small-vessel disease markers were further adjusted. Tract-Based Spatial Statistics analysis indicated strictly lobar cerebral microbleeds associated with lower fractional anisotropy, higher mean diffusivity, and higher radial diffusivity in the internal capsule and corpus callosum after adjusting other cerebral small-vessel disease markers, while only a few voxels remained associated with deep cerebral microbleeds. Diffusion abnormalities gradients along WM tracts containing a cerebral microbleed were not found in fiber tractography analysis. CONCLUSIONS Cerebral microbleeds are associated with widely distributed changes in white matter, despite their focal appearance on SWI.

Abstract
Objective: To determine the clinical features and outcomes of pneumocystic pneumonia (PCP) in patients treated with rituximab for autoimmune diseases. Methods: PCP patients with autoimmune diseases as underlying diseases from January 2009 to April 2019 in Peking University First Hospital (male 67 cases, female 35 cases, age 17-79) were retrospectively reviewed. Patients were grouped as rituximab group and non-rituximab group based on the fact if they were treated with rituximab before the onset of PCP. Demographic data, clinical features, and outcomes of the two groups were analyzed. Results: There were 102 cases altogether, and 7 patients were treated with rituximab before the onset of PCP. Patients in rituximab group were relatively younger than that in non-rituximab group [(32.0±18.7) vs (52.4±14.9) years, P=0.010]. Patients in rituximab group had more CD3(+), CD4(+), CD8(+)T lymphocytes in peripheral blood samples than that in non-rituximab group [(1 306±596) vs (546±439)/μl, (674±401) vs (243±232)/μl, (616±249) vs (282±256)/μl, respectively, all P<0.01]. However, the B lymphocyte count and plasma level of IgG and IgM were significantly lower in rituximab group than that in non-rituximab group [0 (0, 0.2) vs 72 (50.0, 124.4)/μl, 4.0 (2.6, 5.8) vs 9.4 (5.3, 12.0) g/L, 0.3 (0.2, 1.0) vs 1.1 (0.6, 1.8) g/L, respectively, all P<0.05]. The incidence of Cytomegalovirus (CMV) pneumonia was significantly lower in rituximab group (0/7 and 57/95, P=0.007). Other demographic data, the use of corticosteroids, the incidence of severe PCP, mechanical ventilation, intubation, pneumothorax and mediastinal emphysema complications, as well as hospital mortality and length of stay in hospital in the two groups were comparable. Conclusions: In patients treated with rituximab for autoimmune diseases, the number of B lymphocytes in peripheral blood and the plasma level of immunoglobulins but not CD3(+), CD4(+), and CD8(+)T lymphocyte counts may play an important role in the pathogenesis of PCP. These patients are not vulnerable to be complicated with CMV pneumonia.

Abstract
The differential conductance of graphene is shown to exhibit a zero-bias anomaly at low temperatures, arising from a suppression of the quantum corrections due to weak localization and electron interactions. A simple rescaling of these data, free of any adjustable parameters, shows that this anomaly exhibits a universal, temperature- (T) independent form. According to this, the differential conductance is approximately constant at small voltages (V < kBT/e), while at larger voltages it increases logarithmically with the applied bias. For theoretical insight into the origins of this behaviour, which is inconsistent with electron heating, we formulate a model for weak-localization in the presence of nonequilibrium transport. According to this model, the applied voltage causes unavoidable dispersion decoherence, which arises as diffusing electron partial waves, with a spread of energies defined by the value of the applied voltage, gradually decohere with one another as they diffuse through the system. The decoherence yields a universal scaling of the conductance as a function of eV/kBT, with a logarithmic variation for eV/kBT > 1, variations in accordance with the results of experiment. Our theoretical description of nonequilibrium transport in the presence of this source of decoherence exhibits strong similarities with the results of experiment, including the aforementioned rescaling of the conductance and its logarithmic variation as a function of the applied voltage.

Abstract
OBJECTIVE To investigate the role of microRNA-337-5p in osteosarcoma (OS) and its underlying mechanism. PATIENTS AND METHODS The microRNA (microRNA-337-5p) that may be related to OS development was screened out by GEO (Gene Expression Omnibus) database. Survival analysis and ROC curve were performed according to microRNA-337-5p expressions in OA patients. Besides, the correlation between microRNA-337-5p expression and clinical parameters was evaluated by Chi-square analysis. Cox regression analysis was performed to detect the relationship between the overall survival and clinical parameters of OA patients. Subsequently, enriched functions and pathways of microRNA-337-5p were predicted by GESA (gene enrichment sets analysis). MicroRNA-337-5p expression was detected in 65 OS tissue samples and 30 normal tissue samples by qRT-PCR (quantitative Real-Time Polymerase Chain Reaction). For in vitro experiments, after microRNA-337-5p mimics or microRNA-337-5p inhibitor was transfected into OS cells, proliferative and invasive abilities were detected by CCK-8 (Cell Counting Kit-8) and transwell assay, respectively. Finally, Western blot was used to explore the underlying mechanism of microRNA-337-5p in regulating OS. RESULTS MicroRNA-337-5p was overexpressed in serum and tissue samples of OS patients, which was valuable in diagnosing OS. Besides, microRNA-337-5p expression was correlated with the overall survival and necrosis range of OA patients, whereas not correlated with age and sex. GESA indicated that microRNA-337-5p was enriched in ERBB, MAPK, and VEGF pathways. In vitro experiments indicated elevated proliferative and invasive abilities in MG63 and U2OS cells after microRNA-337-5p overexpression. Furthermore, increased expressions of ERBB2, Erk1/2, and VEGF121 were observed in OS cells after microRNA-337-5p overexpression. CONCLUSIONS MicroRNA-337-5p is upregulated in OS tissues, which is an independent prognostic factor in OS. Overexpressed microRNA-337-5p can promote proliferative and invasive abilities of OS cells via activating ERBB, MAPK, and VEGF pathways.

Abstract
Significant advances in the treatment of metastatic colorectal cancer (mcrc) since the early 2000s have led to improved clinical outcomes, including overall survival (os). When fluorouracil was the sole treatment agent for mcrc, os in phase iii studies was approximately 12 months. Now, in 2019, the median os (mos) in the most recent mcrc clinical trials has been approaching 3 years. The biologic agents that target the vascular endothelial growth factor (vegf), epithelial growth factor receptor (egfr), human epidermal growth factor receptor 2 (her2), PD-1, ctla-4, ntrk, and braf pathways play important roles in the mcrc treatment algorithm, given their significant-sometimes dramatic-activity. Emerging data indicate that the choice of a specific biologic at a particular time (line of treatment) for specific patient populations (based on tumour characteristics) is critical. In the present review, we discuss the available evidence for optimal biologic sequencing in the management of mcrc.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the most malignant tumors with poor prognosis, and the interaction between activated pancreatic stellate cells (PSCs) and PDAC cells plays an important role in the development of PDAC. The aim of this study was to identify gene changes in BXPC-3 after cross-talk with PSCs and reveal their potential mechanisms. The gene expression profiling analysis of BXPC-3 was completed after co-culture with primary PSCs for 48 h. The gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes pathway (KEGG) enrichment analyses were performed, and the differentially expressed genes (DEGs) were identified by Agilent GeneSpring GX software. In total, 3657 DEGs were identified in BXPC-3, including 1881 up-regulated genes and 1776 downregulated genes. GO analysis results showed that upregulated DEGs were significantly enriched in biological processes (BP), including peptide metabolic process, response to stress and electron transport chain; the downregulated DEGs were significantly enriched in biological processes, including signaling, multicellular organism development and anatomical structure development. KEGG pathway analysis revealed that 19 pathways were upregulated and 32 pathways were downregulated, and that upregulated DEGs were enriched in protein export and glutathione metabolism, while the downregulated DEGs were enriched in axon guidance and focal adhesion. The top 10 upregulated genes and the top 10 downregulated genes were identified. By constructing PPI network, we selected out 10 key genes (TP53, SRC, IL6, JUN, ISG15, CAD, STAT1, OAS3, OAS1, VIM) and significant pathways. The associated survival analysis was performed and the SRC, IL-6, ISG15, STAT1, OAS3, OAS1 and VIM were proved to be related to worse overall survival time of PDAC patients. In conclusion, the present study indicated that the identified DEGs promote our understanding of the molecular mechanisms underlying the interaction between pancreatic cancer cells and PSCs and might be used as molecular targets in the future to study the role of tumor microenvironment in the progression of PDAC.

Abstract
AIM The association between the use of oral contraceptives and hormone replacement therapy (HRT) or other reproductive factors and the risk of colorectal adenoma (CRA) remains controversial. Our study aimed to review the evidence by conducting a dose-response meta-analysis to investigate this association. METHODS We searched PubMed and Embase databases for relevant studies published until May 2017. Traditional and dose-response meta-analyses were conducted. Sensitivity analysis was performed to evaluate the robustness of the results. Cumulative meta-analysis was used to assess the risk of different oral contraceptive formulations or generations. RESULTS A total of 19 observational studies, with 21 923 CRA cases and 1 030 711 participants, were included in the meta-analysis. Ever HRT use showed a potential inverse association with CRA risk [relative risk (RR) 0.83, 95% CI 0.70-1.00]. The dose-response meta-analysis further demonstrated that HRT use could reduce CRA risk. Compared with no HRT use, the predicted RRs were 0.82 (95% CI 0.67-0.99), 0.76 (95% CI 0.59-0.98) and 0.77 (95% CI 0.62-0.96) for 3, 6 and 9 years of HRT use, respectively. All other factors were not statistically significantly associated with CRA risk. CONCLUSIONS This study indicated that only HRT use might reduce the risk of developing CRA. Any advice regarding HRT use to prevent CRA should be tailored to the individual risks and potential benefits. Large, well-designed prospective studies with long-term follow-up are required to further clarify the aetiology of CRA.
