The distribution of the extrachromosomal DNA molecules in early lung cancer.

Lung cancer (LC) is a highly lethal cancer worldwide. Research on the distribution and nature of extrachromosomal DNA molecules (EcDNAm) in early LC is scarce. In this study, after removing linear DNA and mitochondrial circular DNA, EcDNAm were extracted from two paired LC tissue samples and amplified using rolling circle amplification.

In Situ Polymerization for Manufacture of Multifunctional Delivery Systems for Transcellular Delivery of Nucleic Acids.

Electrostatic self-assembly between negatively charged nucleic acids and cationic materials is the basis for the formulation of the delivery systems. Nevertheless, structural disintegration occurs because their colloidal stabilities are frequently insufficient in a hostile biological environment. To overcome the sequential biological barriers encountered during transcellular gene delivery, we attempted to use in situ polymerization onto plasmid DNA (pDNA) with a variety of functional monomers, including -(3-aminopropyl)methacrylate, (aminopropyl)methacrylamide hydrochloride, 1-vinylimidazole, and 2-methacryloyloxyethylphosphorylcholine and ,'-bis(acryloyl) cystamine.

A real world analysis of secondary BRAF variations after targeted therapy resistance in driver gene positive NSCLC.

Secondary BRAF variations have been identified as a mechanism of resistance to tyrosine kinase inhibitors (TKIs) in patients with driver gene-positive NSCLC. Nevertheless, there is still a lack of consensus regarding the characteristics and subsequent treatment strategies for these patients. We retrospectively reviewed the medical records of patients with driver gene-positive NSCLC who received TKIs therapy at Zhejiang Cancer Hospital between May 2016 and December 2023.

Intake of dietary flavonoids in relation to overactive bladder among U.S. adults: a nutritional strategy for improving urinary health.

Background: The increasing influence of overactive bladder (OAB) on physical as well as mental health of individuals is becoming more pronounced annually, as evidenced by the urge urinary incontinence and nocturia. Symptoms in OAB patients may be influenced by inflammation and oxidative stress. Flavonoids are recognized as significant anti-inflammatory and antioxidant agents, which are commonly available in fruits, tea, vegetables, etc.

Efficacy analysis of the empathy-based attribution analysis-cognitive restructuring-pharmacological treatment model in the management of globus syndrome.

Objective: The aim of this study is to investigate the clinical efficacy of the empathy-based attribution analysis-cognitive restructuring-pharmacological treatment model for the management of globus syndrome.

Method: Sixty-nine newly diagnosed patients with globus syndrome at the Wenzhou People's Hospital Department of Gastroenterology outpatient clinic were enrolled in this study. After obtaining informed consent, patients were randomly assigned to either the observation group (attribution analysis-cognitive restructuring-classical pharmacotherapy; n = 35) or the control group (pharmacotherapy alone; n = 34), with a treatment course of 4 weeks.

Predictive value of inflammation and nutritional index in immunotherapy for stage IV non-small cell lung cancer and model construction.

Identifying individuals poised to gain from immune checkpoint inhibitor (ICI) therapies is a pivotal element in the realm of tailored healthcare. The expression level of Programmed Death Ligand 1 (PD-L1) has been linked to the response to ICI therapy, but its assessment typically requires substantial tumor tissue, which can be challenging to obtain. In contrast, blood samples are more feasible for clinical application.

Multifactor logistic regression was used to build a clinical-imaging model based on clinical factors and a clinical-radiomics model.

Gene therapy by virus-like self-spooling toroidal DNA condensates for revascularization of hindlimb ischemia.

Peripheral arterial diseases (PAD) have been reported to be the leading cause for limb amputations, and the current therapeutic strategies including antiplatelet medication or intervene surgery are reported to not clinically benefit the patients with high-grade PAD. To this respect, revascularization based on angiogenetic vascular endothelial growth factor (VEGF) gene therapy was attempted for the potential treatment of critical PAD. Aiming for transcellular delivery of VEGF-encoding plasmid DNA (pDNA), we proposed to elaborate intriguing virus-like DNA condensates, wherein the supercoiled rigid micrometer-scaled plasmid DNA (pDNA) could be regulated in an orderly fashion into well-defined nano-toroids by following a self-spooling process with the aid of cationic block copolymer poly(ethylene glycol)-polylysine at an extraordinary ionic strength (NaCl: 600 mM).

Efficacy and safety analysis of anlotinib in combination with immune checkpoint inhibitors for second-line and subsequent extensive-stage small-cell lung cancer.

Currently, there is a lack of effective second-line and subsequent treatments for patients with extensive-stage small-cell lung cancer (ES-SCLC), and the establishment of a standardized treatment protocol is still underway. Considering the potential synergistic therapeutic effects of anti-angiogenic drugs and immune checkpoint inhibitors (ICIs), combination therapy could be a viable option for treating lung cancer. This research concentrates on assessing the efficacy and safety of anlotinib in combination with ICIs for the treatment of ES-SCLC.

F-box proteins and gastric cancer: an update from functional and regulatory mechanism to therapeutic clinical prospects.

Gastric cancer (GC) is a prevalent malignancy characterized by significant morbidity and mortality, yet its underlying pathogenesis remains elusive. The etiology of GC is multifaceted, involving the activation of oncogenes and the inactivation of antioncogenes. The ubiquitin-proteasome system (UPS), responsible for protein degradation and the regulation of physiological and pathological processes, emerges as a pivotal player in GC development.
