Background: Observational studies have highlighted the pivotal role of inflammatory cytokines in cirrhosis progression. However, the existence of a causal link between inflammatory cytokines and cirrhosis remains uncertain. In this study, we conducted a bidirectional Mendelian randomization (MR) analysis at a summarized level to illuminate the potential causal relationship between the two variables.

Inhibition of LPCAT3 exacerbates endoplasmic reticulum stress and HBV replication.

Background: Altered phospholipid metabolism plays a key role in changing the immune microenvironment and severely affecting T-cell function. LPCAT3 is one of the vital enzymes regulating phospholipid metabolism. This study aims to verify the effect of LPCAT3 on HBV replication in vitro and the chronic progression of hepatitis B infection based on the results of lipidomic.

Biomolecule-regulation of fluorescent probe signaling: Homogeneous rapid portable protease sensing in serum.

Background: As is well documented, prostate cancer (PCa) being the second most prevalent cancer in men worldwide, emphasizing the importance of early diagnosis for prognosis. However, conventional prostate-specific antigen (PSA) testing lacks sufficient diagnostic efficiency due to its relatively low sensitivity and limited detection range. Mounting evidence suggests that matrix metalloproteinase 9 (MMP-9) expression increases with the aggressive behavior of PCa, highlighting the significance of detecting the serum level of MMP-9 in patients.

Steric Hindrance-Mediated Enzymatic Reaction Enable Homogeneous Dual Fluorescence Indicators Aptasensing of Hepatocellular Carcinoma CTCs.

Circulating tumor cells (CTCs) serve as important biomarkers in the liquid biopsy of hepatocellular carcinoma (HCC). Herein, a homogeneous dual fluorescence indicators aptasensing strategy is described for CTCs in HCC, with the core assistance of a steric hindrance-mediated enzymatic reaction. CTCs in the sample could specifically bind to a 5'-biotin-modified glypican-3 (GPC3) aptamer and remove the steric hindrance formed by the biotin-streptavidin system.

DNAzyme and controllable cholesterol stacking DNA machine integrates dual-target recognition CTCs enable homogeneous liquid biopsy of breast cancer.

Although circulating tumor cells (CTCs) have demonstrated considerable importance in liquid biopsy, their detection is limited by low concentrations and complex sample components. Herein, we developed a homogeneous, simple, and high-sensitivity strategy targeting breast cancer cells. This method was based on a non-immunological stepwise centrifugation preprocessing approach to isolate CTCs from whole blood.

Nucleic Acid and Nanomaterial Synergistic Amplification Enables Dual Targets of Ultrasensitive Fluorescence Quantification to Improve the Efficacy of Clinical Tuberculosis Diagnosis.

Interferon-γ (IFN-γ) release assays (IGRAs) are constrained by the limited diagnostic performance of a single indicator and the excessive () antigen stimulation time. This study presents a simultaneous, homogeneous, rapid, and ultrasensitive fluorescence quantification strategy for IFN-γ and IFN-γ-induced protein 10 (IP-10). This method relies on the high-affinity binding of aptamers to IFN-γ and IP-10, the enzyme-free catalytic hairpin assembly reaction, and the heightened sensitivity of CdTe quantum dots to Ag and hairpin structure C-Ag-C and carbon dots to Hg and hairpin structure T-Hg-T.

Methods: Leukemia cells from bone marrow of newly diagnosed T-ALL patients were isolated, and the leukemia cells were inoculated into NCG mice via tail vein. The proportion of hCD45 positive cells in peripheral blood of the mice was detected regularly by flow cytometry, and the infiltration of leukemia cells in bone marrow, liver, spleen and other organs of the mice was detected by pathology and immunohistochemistry.

Transcriptional and Epigenetic Alterations in the Progression of Non-Alcoholic Fatty Liver Disease and Biomarkers Helping to Diagnose Non-Alcoholic Steatohepatitis.

Non-alcoholic fatty liver disease (NAFLD) encompasses a broad spectrum of conditions from simple steatosis (non-alcoholic fatty liver (NAFL)) to non-alcoholic steatohepatitis (NASH), and its global prevalence continues to rise. NASH, the progressive form of NAFLD, has higher risks of liver and non-liver related adverse outcomes compared with those patients with NAFL alone. Therefore, the present study aimed to explore the mechanisms in the progression of NAFLD and to develop a model to diagnose NASH based on the transcriptome and epigenome.

Lnc-AIFM2-1 promotes HBV immune escape by acting as a ceRNA for miR-330-3p to regulate CD244 expression.

Chronic hepatitis B (CHB) virus infection is a major risk factor for cirrhosis and hepatocellular carcinoma (HCC). Hepatitis B virus (HBV) immune escape is regulated by the exhaustion of virus-specific CD8 T cells, which is associated with abnormal expression of negative regulatory molecule CD244. However, the underlying mechanisms are unclear.

Preoperative antiplatelet therapy may be a risk factor for postoperative ischemic complications in intracranial hemorrhage patients.

Simultaneous Homogeneous Fluorescence Detection of AFP and GPC3 in Hepatocellular Carcinoma Clinical Samples Assisted by Enzyme-Free Catalytic Hairpin Assembly.

Simultaneous sensitive and cost-effective detection of multiple tumor markers has shown great potential for cancer diagnostics. Herein, we reported a simple enzyme-free parallel catalytic hairpin assembly (CHA) amplification strategy with -methyl mesoporphyrin IX (NMM) and quantum dots (QDs) as signal reporters for the homogeneous fluorescent simultaneous detection of alpha-fetoprotein (AFP) and glypican-3 (GPC3). Upon selective binding, the released single-stranded DNA (ssDNA) from the two-aptamer double-stranded DNA (dsDNA) probes triggers CHA amplification, further releasing the G-quadruplex sequence and Ag from the C-Ag-C structures at the same time.

A nomogram to predict the risk of postoperative intracranial rebleeding in patients with spontaneous intracranial hematoma.

The 30-day mortality rate of spontaneous cerebral hemorrhage (ICH) is approximately 30-50%. Surgery may improve the prognosis of patients with severe ICH. However, ICH survivors after surgery still face the risks of postoperative intracranial rebleeding (PIB), and clinical tools that accurately predict the risk of PIB occurrence are not available.

Aspirin does not affect hematoma growth in severe spontaneous intracranial hematoma.

Hematoma growth (HG) affects the prognosis of patients with spontaneous intracranial hematoma (ICH), but there is still a lack of evidence about the effects of aspirin (acetylsalicylic acid, ASA) on HG in patients with severe ICH. This study retrospectively analyzed patients with severe ICH who met the inclusion and exclusion criteria in Beijing Tiantan Hospital, Capital Medical University, between January 1, 2015, and July 31, 2019. Severe ICH patients were divided into ASA group and nASA groups according to ASA usage, and the incidence of HG between the groups was compared.
