Naringenin can improve the function of intestinal endocrine cells and protect against diabetes-related intestinal injury, which may be related to the mechanism of necrotic apoptosis mediated by MLKL.
To evaluate the antifungal activity of minocycline (MIN), this study followed the methodological framework of a scoping review, systematically searched Chinese and English databases, and included 36 studies for inductive analysis. Results showed that MIN has a narrow direct antifungal spectrum, mainly acting on some Candida albicans strains. However, when combined with antifungal agents, it exerted a significant synergistic effect against various drug-resistant fungi. Its direct mechanisms included inhibiting hyphal transition and biofilm formation, as well as inducing oxidative stress and apoptosis. The synergistic mechanisms involved disrupting calcium homeostasis, destroying biofilm structure, increasing cell membrane permeability, interfering with amino acid metabolism and depending on the ergosterol biosynthesis gene 3 (ERG3). Both in vitro and in vivo studies consistently confirmed its efficacy, though it was affected by factors such as biofilm maturity, combination regimens and strain differences. MIN had clear antifungal potential, supported by substantial evidence on its mechanisms and preclinical data, but clinical translation remained inadequate. Future efforts should focus on conducting high-level preclinical validation and proof-of-concept clinical trials to clarify its efficacy, safety and optimal treatment regimens in humans, thereby promoting its clinical application.
To establish a colloidal gold immunochromatographic method for the rapid detection of cotinine in urines.
To prepare the colloidal gold-labeled antibody probe, optimization of the pH value and the amount of antibody labeling (COT-Mab) was carried out. Following this, the coating concentrations of the cotinine antibody (COT-BSA) for the test (T) line and the sheep anti-mouse immunoglobulin G (IgG) for the control (C) line were also optimized. Subsequently, a colloidal gold immunochromatographic strip was assembled. Finally, the sensitivity of the strip was evaluated.
The optimal conditions established for the colloidal gold immunochromatographic strip were as followings, pH value of 6.5, COT-Mab concentration of 10.00 μg·mL-1, COT-BSA concentration of 0.10 mg·mL-1, and sheep anti-mouse IgG concentration of 1.00 mg·mL-1. The visual detection limit and the cut-off value were 0.01 and 0.20 μg·mL-1, respectively. Within 15 minutes, this method enabled qualitative analysis of cotinine in urines.
The method has good specificity and accuracy, as well as convenient operation and excellent reproducibility, which can be used for on-site detection and rapid initial screening of smokers and non-smokers during drug clinical trials.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic disorder characterized by excessive hepatic lipid accumulation resulting from multiple etiological factors. In recent years, changes in lifestyle have contributed to a rising incidence of NAFLD, making it a significant public health concern. Traditional Chinese medicine (TCM), with its multi-component, multi-pathway, and multi-target characteristics, has demonstrated unique advantages and research value in the prevention and treatment of NAFLD. Polygonum cuspidatum is a representative herbal medicine in this context and has been confirmed to possess various pharmacological activities, including anti-inflammatory, antioxidant, and hepatoprotective effects. However, its specific active components and mechanisms of action remain incompletely elucidated. Therefore, this article systematically reviews Chinese and English literature on Polygonum cuspidatum and its active components in the treatment of NAFLD. The results indicate that the core active components of Polygonum cuspidatum against NAFLD include resveratrol, polydatin, emodin, among others. The mechanisms involve multiple pathways, such as the regulation of lipid metabolism, improvement of glucose metabolism and insulin resistance, anti-inflammatory effects, antioxidant stress response, and modulation of gut microbiota. This review aims to provide insights and references for further mechanistic research and clinical application of Polygonum cuspidatum.
