Background: Epidermal growth factor receptor (EGFR) is a key protein in cellular signaling that is overexpressed in many human cancers, making it a compelling therapeutic target. On-target severe skin toxicity has limited its clinical application. Dual-targeting therapy represents a novel approach to overcome the challenges of EGFR-targeted therapies.

Epigenetic-targeted therapy has been applied in the treatment of several types of cancer. Herein, based on the synergistic antitumor effects of co-targeting HDACs and EZH2 in some hematological malignancies, a novel series of tazemetostat-based HDACs/EZH2 dual inhibitors were rationally designed, synthesized, and biologically evaluated. Satisfyingly, compounds 22a and 22b were identified as potent HDACs/EZH2 dual inhibitors with robust antiproliferative activities against one diffuse large-cell B cell lymphomas (DLBCL) cell line harboring EZH2 mutation and multiple acute myeloid leukemia (AML) cell lines.

Acute lung injury (ALI), a multifactorial pathological condition, manifests through heightened inflammatory responses, compromised lung epithelial-endothelial barrier function, and oxidative stress, potentially culminating in respiratory failure and mortality. This study explores the intricate interplay between two crucial cellular mechanisms-extracellular vesicles (EVs) and autophagy-in the context of ALI pathogenesis and potential therapeutic interventions.EVs, bioactive membrane-bound structures secreted by cells, serve as versatile carriers of molecular cargo, facilitating intercellular communication and significantly influencing disease progression.

Article Synopsis
  • - Traumatic brain injury (TBI) and Alzheimer's disease have similar features, such as neuronal loss and cognitive deficits, and TBI can worsen Alzheimer's-like symptoms, potentially leading to the disease's development.
  • - Nanocarriers are being explored to deliver small interfering RNAs (siRNAs) across the blood-brain barrier, allowing for targeted silencing of genes related to TBI and Alzheimer's without the non-specific effects of traditional drugs.
  • - While siRNA gene silencing shows great promise in halting disease progression by targeting gene expression, challenges remain in effectively delivering siRNAs to the brain, but nanoparticles are emerging as a promising solution for this drug delivery issue.

Skeletal muscle is striated muscle that moves autonomously and is innervated by peripheral nerves. Peripheral nerve injury is very common in clinical treatment. However, the commonly used treatment methods often focus on the regeneration of the injured nerve but overlook the pathological changes in the injured skeletal muscle.

Radiation-induced intestinal injury (RIII) is one of the most common intestinal complications caused by radiotherapy for pelvic and abdominal tumors and it seriously affects the quality of life of patients. However, the treatment of acute RIII is essentially symptomatic and nutritional support treatment and an ideal means of prevention and treatment is lacking. Researchers have conducted studies at the cellular and animal levels and found that some chemical or biological agents have good therapeutic effects on RIII and may be used as potential candidates for clinical treatment.

Background: To assess the efficacy of the epidemic prevention measures of the "closed-loop" system adopted by the Beijing 2022 Olympic Winter Games (BOWG).

Methods: We retrospectively collected and analyzed information, including age, sex, nationality, vaccination status, date of diagnosis, and date of entry, from 280 SARS-CoV-2-positive individuals identified during the BOWG. A susceptibility-exposed-infectious-remove model was employed to evaluate the effectiveness of epidemic prevention strategies on controlling the spread of SARS-CoV-2 under different scenarios during the BOWG.

Chemotherapeutics can induce immunogenic cell death (ICD) by triggering autophagy and mediate antitumor immunotherapy. However, using chemotherapeutics alone can only cause mild cell-protective autophagy and be incapable of inducing sufficient ICD efficacy. The participation of autophagy inducer is competent to enhance autophagy, so the level of ICD is promoted and the effect of antitumor immunotherapy is highly increased.

Objectives: Airway management during cardiopulmonary resuscitation is particularly important for patients with out-of-hospital cardiac arrest (OHCA). This study was performed to compare the efficacy of the most commonly used out-of-hospital airway management methods in increasing the survival to discharge in patients with OHCA.

Methods: We screened all relevant literature from database inception to 21st January 2019 in PubMed, Web of Science, Embase, and the Cochrane Library.

Background: To investigate and understand the determinants of decisions not to attempt resuscitation following out-of-hospital cardiac arrest, to contribute to establishing rules that are appropriate to China.

Methods: We recruited participants through directors of emergency medical services across China. A 28-question web survey was available between February 5 and March 6, 2021 that targeted demographic information and views on emergency work and cardiopulmonary resuscitation.

Gliomas are the most malignant and common tumors of the human brain, and the prognosis of glioma patients is extremely poor. MicroRNAs (miRNAs or miRs) play critical roles in different types of cancer by performing post‑transcriptional regulation of gene expression. Although miR‑218 has been demonstrated to be decreased in gliomas, its role in gliomas remains largely unknown.

Objectives: To explore the potential of SARS-CoV-2 spread during air travel and the risk of in-flight transmission.

Methods: We enrolled all passengers and crew suspected of being infected with SARS-CoV-2, who bounded for Beijing on international flights. We specified the characteristics of all confirmed cases of COVID-19 infection and utilised Wells-Riley equation to estimate the infectivity of COVID-19 during air travel.

Metal-organic frameworks (MOFs) as a peroxidase mimic have been integrated with glucose oxidase (GOx) to achieve one-step glucose detection. However, limited by the loading amount of GOx, the performances of the developed glucose sensing assays still remain to be further improved to meet sensing requirements in diverse biological samples. Herein, with Fe3+ as the metal ion and 2-amino-benzenedicarboxylic acid as a ligand, a fluorescent Fe-based organic framework (NH2-MIL-101) with peroxidase-like activity was synthesized.

Article Synopsis
  • The study analyzed 478 COVID-19 patients from four major cities in China (excluding Wuhan) to understand the epidemiological and clinical characteristics of the virus during the pandemic.
  • The average patient age was 46.9 years, with common symptoms including fever, cough, and fatigue; 65.5% of cases were indigenous, while 34.5% were imported.
  • The findings revealed that imported cases differed significantly from indigenous ones in severity and symptoms, highlighting the shift from imported to local infections and emphasizing the importance of controlling spread in local areas.

The aim of this study is to explore whether the single nucleotide polymorphism rs2275294 in the ZNF512B gene is related to the length of survival of patients with amyotrophic lateral sclerosis (ALS). This prospective study examined 212 patients with ALS, who were genotyped at the rs2275294 locus in ZNF512B using the ligase method. Genotype was compared with clinical data and survival.

Background: Respiratory failure in patients with Guillain-Barré syndrome (GBS) can lead to serious complications and dysfunctions, emphasizing the importance of early detection. The C-reactive protein-to-albumin ratio (CAR) is emerging as a novel inflammatory marker for predicting neurological outcome. We aimed to identify the association of CAR with respiratory failure and short-term outcome in GBS patients.
