Systemic lupus erythematosus (SLE) is a chronic multisystem inflammatory disease associated with autoantibody formation. Lupus nephritis (LN) is one of the most severe organ manifestations of SLE. The inflammatory response is a key factor in kidney injury, and the NLRP3 inflammasome is frequently associated with the pathogenesis of LN. Sirtuin 1 (SIRT1), a nicotinamide adenine dinucleotide (NAD +)-dependent histone deacetylase, is a promising therapeutic target for preventing renal injury. However, the mechanism of SIRT1 in LN remains unclear...

Acute myeloid leukemia (AML) is one of the most common malignant and aggressive hematologic tumors, and risk stratification is indispensable to ensure proper treatment. But immune-related long noncoding RNAs (ir-lncRNAs) pairs prognostic risk models used to stratify AML have yet to be reported. In this study, we established a prognostic risk model based on eight ir-lncRNAs pairs using LASSO-penalized Cox regression analysis and successfully validated the model in an independent cohort. According to risk scores, patients were divided into a high-risk group and a low-risk group...

Triple negative breast cancer (TNBC) is the most aggressive and malignant subtype in breast cancer. Immunotherapy is a currently promising and effective treatment for TNBC, while not all patients are responsive. Therefore, it is necessary to explore novel biomarkers to screen sensitive populations for immunotherapy. All mRNA expression profiles of TNBC from The Cancer Genome Atlas (TCGA) database were clustered into two subgroups by analyzing tumor immune microenvironment (TIME) with single sample gene set enrichment analysis (ssGSEA)...

Autoimmune hepatitis (AIH) is often complicated with immune diseases, which greatly affected the course and clinical outcome of AIH. We aimed to systematically assess clinical characteristics, prognosis in autoimmune hepatitis accompanied by immune diseases. Clinical records of 358 patients with AIH from Beijing Ditan Hospital in China were retrospectively reviewed. The clinical features of AIH with immune diseases were compared retrospectively, including clinical characteristics, prognosis and outcome. Prevalence of immune diseases in patients with AIH was 26...

Thrombosis has been associated with severity and mortality in COVID-19. SARS-CoV-2 infects the host via its spike protein. However, direct effects of spike proteins from SARS-CoV-2 variants on platelet activity and coagulability have not been examined. An ethically approved ex vivo study was performed under a preplanned power analysis. Venous blood was collected from 6 healthy subjects who gave prior written consent. The samples were divided into 5 groups: without spike proteins (group N) and with spike proteins derived from alpha, beta, gamma, and delta SARS-CoV-2 variants (groups A, B, C, and D, respectively)...

HAND2 antisense RNA 1 (HAND2-AS1) is a newly recognized lncRNA encoded by a gene on 4q34.1. This lncRNA has 10 exons and is predicted to have a positive effect on expression of certain genes. HAND2-AS1 is mainly considered as a tumor suppressive lncRNA in different tissues. Moreover, HAND2-AS1 has been shown to regulate expression of several targets with possible roles in the carcinogenesis through serving as a sponge for miRNAs. This lncRNA can also influence activity of BMP, TGF-β1, JAK/STAT and PI3K/Akt pathways...

Kawasaki disease is a pressing acute self-limiting inflammatory disorder disease which lack of specific biomarkers. Our research aims to investigate the serum expression of a novel immune regulator PK2 in children with Kawasaki disease and to evaluate the ability of PK2 to predict Kawasaki disease. A total of 70 children with Kawasaki disease in the Children's Hospital of Chongqing Medical University who were first diagnosed, 20 children with common fever admitted to hospital due to bacterial infection during the same period, and 31 children underwent physical examination were included in this study...

Secondary acute myeloid leukemia (sAML) may develop following a prior therapy or may evolve from an antecedent hematological disorder such as Fanconi Anemia (FA). Pathophysiology of leukemic evolution is not clear. Etoposide (Eto) is a chemotherapeutic agent implicated in development of sAML. FA is an inherited bone marrow (BM) failure disease characterized by genomic instability and xenobiotic susceptibility. Here, we hypothesized that alterations in the BM niche may play a critical/driver role in development of sAML in both conditions...

To evaluate the intima media thickness of carotid arteries (IMT) and its clinical, laboratory and treatment correlates in Behcet's disease (BD). Systematic search of EMBASE and PubMed databases from January 2016 to October 2022; we employed random effect meta-analyses for continuous outcomes and Peto's odds ratio for rare events. The meta-analysis included 36 case control studies: the IMT was greater in BD (n = 1103) than in controls (n = 832) (p < 0.0001) with wide heterogeneity (I2  = 86...

Glycoprotein 90K, encoded by the interferon-stimulated gene LGALS3BP, displays broad antiviral activity. It reduces HIV-1 infectivity by interfering with Env maturation and virion incorporation, and increases survival of Influenza A virus-infected mice via antiviral innate immune signaling. Its antiviral potential in SARS-CoV-2 infection remains largely unknown. Here, we analyzed the expression of 90K/LGALS3BP in 44 hospitalized COVID-19 patients at multiple levels. We quantified 90K protein concentrations in serum and PBMCs as well as LGALS3BP mRNA levels...

The mammalian lungs encounter several pathogens, but have a sophisticated multi-phase immune defense. Furthermore, several immune responses to suppress pulmonary pathogens can damage the airway epithelial cells, particularly the vital alveolar epithelial cells (pneumocytes). The lungs have a sequentially activated, but overlapping, five phase immune response to suppress most pathogens, while causing minimal damage to the airway epithelial cells. Each phase of the immune response may suppress the pathogens, but if the previous phase proves inadequate, a stronger phase of immune response is activated, but with an increased risk of airway epithelial cell damage...

Anti-human epidermal growth factor receptor-2 (anti-HER2) therapy has shown excellent efficacy in patients with HER2 overexpression and amplification. Although HER2 mutations are rarely expressed in several cancers, when they occur, they can activate the HER2 signaling pathway. In recent years, studies have shown that anti-HER2 drugs have promising efficacy in patients with HER2 mutations. Based on keywords, we searched databases, such as PubMed, Embase, and Cochrane Library, and the main conference abstracts...

The eradication rate of Helicobacter pylori (H. pylori) decreased gradually. This study aimed to analyze the efficacy and safety of a 14-day combination of vonoprazan and amoxicillin as the first-line eradication therapy for H. pylori infection and compared them with those of the bismuth quadruple therapy. A prospective randomized clinical trial (RCT) was designed, involving patients with H. pylori infection in 6 institutions who did not receive any treatment yet. They were randomly assigned into the VA-dual group (vonoprazan 20 mg b...

Anti-PD-1 immunotherapy has been widely applied in patients with some types of lymphoma. Classical Hodgkin's lymphoma (cHL) is highly sensitive to immunotherapy, but non-Hodgkin's lymphoma (NHL) does not show a good response. Studies have indicated that haematopoietic progenitor kinase 1 (HPK1) suppresses T cells and reduces antitumour immunity. Therefore, HPK1 inhibitors may restore and elicit antitumour immune responses and are promising candidate drug targets for cancer immunotherapy. We first explored the Gene Expression Profile Interactive Analysis (GEPIA) database and predicted that HPK1 expression was increased in diffuse large B-cell lymphoma (DLBCL) and associated with Nod-like receptor protein 3 (NLRP3) expression...

Giant cell tumors of the bone (GCTB) are considered moderately malignant bone tumors. Denosumab, as a neoadjuvant therapy, provides new possibilities for treating GCTB. However, even after multiple studies and long-term clinical trials, there are limitations in the treatment process. Research data and Medical Subject Headings terms related to denosumab and GCTB were collected from January 2010 to October 2022 using the Web of Science and MeSH ( https://meshb.nlm.nih.gov ) browsers. These data were imported into CiteSpace and VOSviewer softwares for bibliometric analysis...

A high risk of thrombosis is seen in patients with newly diagnosed multiple myeloma (NDMM), particularly those treated with immunomodulatory drugs (IMiDs). Large cohorts addressing the thrombosis issue of NDMM patients in Asia are lacking. We retrospectively analyzed the clinical information of NDMM patients diagnosed in Zhongshan Hospital Fudan University, a national medical center, from January 2013 to June 2021. Death and thrombotic events (TEs) were the endpoints. To investigate risk factors for TEs, the Fine and Gray competing risk regression models were created, in which unrelated deaths were labeled as competing risk events...

Over the past two decades, there has been a significant growth in articles focusing on the genetics of pheochromocytoma and paraganglioma (PPGL). We used bibliometric methods to investigate the historical changes and trend in PPGL research. There was a total of 1263 articles published in English from 2002 to 2022 included in our study. The number of annual publications and citations in this field has been increasing in the past 20 years. Furthermore, most of the publications originated from the European countries and the United States...

Idiopathic inflammatory myopathy (IIM) are heterogeneous autoimmune diseases that primarily affect the proximal muscles. IIM subtypes include dermatomyositis (DM), polymyositis (PM), and anti-synthetase syndrome (ASS). Metabolic disturbances may cause irreversible structural damage to muscle fibers in patients with IIM. However, the metabolite profile of patients with different IIM subtypes remains elusive. To investigate metabolic alterations and identify patients with different IIM subtypes, we comprehensively profiled plasma metabolomics of 46 DM, 13 PM, 12 ASS patients, and 30 healthy controls (HCs) using UHPLC-Q Exactive HF mass spectrometer...

The role of anti-thyroid peroxidase antibodies (anti-TPO Abs) in the development of abnormal thyroid function tests (DYSTHYR) during treatment with immune checkpoint inhibitors (ICIs) is not fully understood; moreover, controversial data exist about the relationship between ICI-related thyroid dysfunction (TD) and survival. We retrospectively analyzed the onset or the worsening of DYSTHYR in patients treated with programmed cell death protein-1 (PD-1) or its ligand (PD-L1) inhibitors between 2017 and 2020. In patients without previous TD, we focused on the association between baseline anti-TPO Abs level and DYSTHYR...
