Optimising Beyond-Use Date Management and Workload to Reduce Intravenous Medication Errors: A Targeted Intervention Study.

Aim(s): To evaluate the effectiveness of targeted interventions in optimising Beyond-Use Date (BUD) management and workload distribution to reduce intravenous (IV) medication errors and improve patient safety in a resource-limited hospital setting.

Design: This study employed a pre- and post-intervention observational design.

Methods: A four-month intervention was conducted at a large tertiary hospital in China, following a baseline assessment of IV medication practices.

Discovery of novel and selective farnesoid X receptor antagonists through structure-based virtual screening, preliminary structure-activity relationship study, and biological evaluation.

Farnesoid X receptor (FXR) is a bile acids receptor and plays a crucial role in regulating bile acids, lipids, and glucose metabolism. Previous research suggests that inhibiting FXR activation can be beneficial in reducing cholesterol and low-density lipoprotein cholesterol (LDL-C) levels, offering potential treatment options for metabolic syndrome with lipid disorders. Herein, we report p-acetylaminobenzene sulfonate derivatives as a novel scaffold of FXR antagonists by multistage screening.

Discovery of 3-oxo-1,2,3,4-tetrahydropyrido[1,2-a]pyrazin derivatives as SARS-CoV-2 main protease inhibitors through virtual screening and biological evaluation.

The COVID-19 caused by SARS-CoV-2 has led to a global pandemic that continues to impact societies and economies worldwide. The main protease (M) plays a crucial role in SARS-CoV-2 replication and is an attractive target for anti-SARS-CoV-2 drug discovery. Herein, we report a series of 3-oxo-1,2,3,4-tetrahydropyrido[1,2-a]pyrazin derivatives as non-peptidomimetic inhibitors targeting SARS-CoV-2 M through structure-based virtual screening and biological evaluation.

Differences in the phenotypes and transcriptomic signatures of chimeric antigen receptor T lymphocytes manufactured electroporation or lentiviral transfection.

Chimeric antigen receptor (CAR)-T cell therapy is an innovative treatment for CD19-expressing lymphomas. CAR-T cells are primarily manufactured via lentivirus transfection or transposon electroporation. While anti-tumor efficacy comparisons between the two methods have been conducted, there is a current dearth of studies investigating the phenotypes and transcriptome alterations induced in T cells by the two distinct manufacturing methods.

Discovery of 2-(furan-2-ylmethylene)hydrazine-1-carbothioamide derivatives as novel inhibitors of SARS-CoV-2 main protease.

The COVID-19 posed a serious threat to human life and health, and SARS-CoV-2 M has been considered as an attractive drug target for the treatment of COVID-19. Herein, we report 2-(furan-2-ylmethylene)hydrazine-1-carbothioamide derivatives as novel inhibitors of SARS-CoV-2 M developed by in-house library screening and biological evaluation. Similarity search led to the identification of compound F8-S43 with the enzymatic IC value of 10.

Anti-oral Squamous Cell Carcinoma Effects of a Potent TAZ Inhibitor AR-42.

Oral squamous cell carcinoma (OSCC) is one of the most common malignancies worldwide. Although great progress has been made in diagnosis and treatment strategies in recent years, the 5-year survival rate of OSCC patients is still disappointingly low. Hence, there is still an unmet medical need for sufferers with OSCC.

Association Between Toothbrushing and Behavioral Risk Factors of Non-communicable Diseases: A population Based Survey of 4500 adults in China.

Non-communicable Disease (NCD) related behavioral risk factors (BRF) plays a crucial role in NCD prevention, as does oral hygiene behavior in oral health promotion. We examined the association between NCD BRF and toothbrushing using data from a population-based survey, which recruited 4485 adults aged 18+ years, in Chongqing city, China. Prevalence of five NDC BRF and their clustering within individual were determined by toothbrushing frequency.

Preclinical assessment of histone deacetylase inhibitor quisinostat as a therapeutic agent against esophageal squamous cell carcinoma.

Esophageal squamous cell carcinoma (ESCC) is one of the most serious life-threatening malignancies. Although chemotherapeutic targets and agents for ESCC have made much progress recently, the efficacy is still unsatisfactory. Therefore, there is still an unmet medical need for patients with ESCC.

Toothbrushing, Blood Glucose and HbA1c: Findings from a Random Survey in Chinese Population.

Both diabetes and periodontal disease are prevalent in China. Poor oral hygiene practice is the major cause of periodontal disease. An association between oral hygiene practice and blood glucose level was reported in individuals with diabetes, but not in the general population.

pH responsive PEGylation through metal affinity for gene delivery mediated by histidine-grafted polyethylenimine.

Polyethylene glycol (PEG) has been used to enhance the stability of a gene delivery system. The most commonly used approach is to add the PEG molecule by way of chemical conjugation. In this study, we prepared PEG-bearing nitrilotriacetic acid (ntaPEG) followed by chelation with either nickel or zinc ions.

Using trehalose delivered by the intramuscular injection of plasmid DNA as an adjuvant for transgene expression.

Background: Intramuscular injection is a popular and effective approach to administer naked plasmid for transgene expression. The use of an adjuvant can provide a straightforward approach for enhancing transgene expression.

Methods: Expression plasmid was formulated with various concentrations of trehalose for injection into the skeletal muscles of C57BL/6 mice.

Trehalose enhances transgene expression mediated by DNA-PEI complexes.

Using enhancers to improve the transfection efficiency of polyethylenimine (PEI) can circumvent the needs of chemical modifications as well as subsequent purification and characterization of the modified PEI. In this study, we found that incorporating trehalose into the transfection reagent could improve the transgene expression mediated by DNA-PEI complexes. Such enhancements were not observed when trehalose was replaced by other disaccharides.

Using disaccharides to enhance in vitro and in vivo transgene expression mediated by a lipid-based gene delivery system.

Background: Lipid-based vectors have been widely applied to in vivo and in vitro gene delivery. Disaccharides can effectively stabilize lipid membranes. This study examined whether disaccharides could enhance the transgene expression mediated by lipid-based vectors.

Dependence of transgene expression and the relative buffering capacity of dextran-grafted polyethylenimine.

Branched polyethylenimine (PEI) is a cationic polymer capable of forming self-assembly complexes with DNA to become a highly efficient agent used in gene delivery. Conjugation through the primary amines of PEI is a most commonly used approach further to enable the targeting delivery or to improve the stability of the DNA-polymer complexes. An understanding of how the conjugation affects the transfection mechanisms can help in the design of efficient polycationic vectors.
