Coronary heart disease is an ischemic condition characterized by vascular stenosis or obstruction caused by coronary atherosclerosis, resulting in myocardial ischemia, hypoxia, or necrosis. It is one of the leading causes of death in both urban and rural populations in China. Safflower yellow pigments, the main active components of the traditional Chinese herbal medicine safflower, are primarily composed of quinochalcone compounds, including hydroxysafflor yellow A and anhydrosafflor yellow B—of which hydroxysafflor yellow A is the principal component. Studies have demonstrated that these pigments can improve myocardial ischemia, reduce ischemia-reperfusion injury, alleviate atherosclerotic damage, and address risk factors associated with coronary heart disease. This review aimed to systematically and comprehensively summarize the mechanisms of action of safflower yellow pigments and their active components in the context of coronary heart disease and its related risk factors.

Drug-induced liver injury (DILI) represents a prevalent adverse event associated with medication use. However, the exact mechanisms underlying DILI remain incompletely understood, and the lack of specific diagnostic and prognostic biomarkers poses significant challenges to the clinical diagnosis and treatment of this condition. Consequently, our study aimed to endeavor to identify serum and fecal metabolic biomarkers, enabling more accurate DILI diagnosis and improved prediction of chronic progression.

Untargeted metabolomics analysis was performed on serum and fecal samples obtained from a cohort of 32 DILI patients (causality confirmed via the updated Roussel Uclaf Causality Assessment Method) and 36 healthy controls. Utilizing techniques such as partial least squares-discriminant analysis modeling and t-tests, we identified significantly differentially expressed metabolites and metabolite sets. Causality assessment was performed using the updated Roussel Uclaf Causality Assessment Method.

The findings from the analysis of serum and fecal metabolomics association pathways suggested that perturbations in bile acid metabolism might serve as potential mechanisms underlying the progression of DILI. Our study revealed 22 overlapping differential metabolites between serum and feces, displaying significant concentration differences between the DILI and healthy control groups. Notably, we identified chenodeoxycholic acid and deoxycholic acid as promising markers that not only distinguished DILI patients from healthy individuals but also exhibited predictive potential for DILI chronicity.

The integrated analysis of serum and fecal metabolites uncovers the significant disruption of bile acid metabolites as a key contributing factor in the pathogenesis of DILI. Our study offers promising potential biomarkers for the diagnosis and prognosis of DILI, paving the way for a novel perspective in the realm of DILI diagnosis and treatment.

Metabolic syndrome (MetS) is associated with a plethora of different comorbidities. Exploring its key molecular mechanisms, such as advanced glycation end product and its receptor (AGE/RAGE) pathway, holds great potential. Numerous sources agree that targeting the AGE/RAGE pathway is a potential therapeutic strategy for MetS. However, the regulation of AGE/RAGE by microRNAs (miRNAs) in the context of MetS is still poorly understood. This review aimed to provide a systematic picture of the influence of miRNAs on AGE/RAGE in the context of MetS, with a particular focus on its ligands and receptors. This review achieves this in two ways: through an inductive “bottom-up” approach realized by a classical descriptive literature search, and through a deductive/synthetic “top-down” approach based on carefully selected miRNA profiling studies in MetS and its comorbidities. Although the initial inductive approach allowed the identification of some miRNAs of interest, almost all articles on this topic focus on the regulation of processes exclusively involved in atherogenesis. The new deductive approach has broadened the research horizon: It has enabled the discovery of new promising miRNAs and allowed for ranking different comorbid pathologies in MetS according to the degree of miRNA dysregulation of AGE/RAGE. Thus, in addition to atherosclerosis, significant miRNA dysregulation of AGE/RAGE was also described in MetS, particularly in immune cells, as well as in subcutaneous adipose tissue in obesity. This review, along with the novel approaches to systematizing the data contained therein may contribute to the understanding of MetS pathogenesis and the search for targets for the treatment of MetS.

Chronic hepatitis B virus (HBV)-infected patients may exhibit liver fibrosis and other pathological changes despite normal alanine aminotransferase (ALT). This study aimed to assess the efficacy and safety of tenofovir amibufenamide (TMF) in chronic HBV-infected patients with normal ALT levels.

The ongoing PROMOTE study (NCT05797714) is the first prospective, multicenter, randomized, open-label, blank-controlled clinical trial involving chronic HBV-infected patients with normal ALT levels. Participants were randomized in a 1:1 ratio to receive either TMF (TMF group) or no treatment (blank control group). The primary efficacy endpoint was the proportion of participants achieving HBV DNA levels <20 IU/mL at 48 weeks.

A total of 197 participants were enrolled, with 95 in the TMF group and 102 in the blank control group. At 48 weeks, a significantly greater proportion of participants in the TMF group achieved HBV DNA levels <20 IU/mL compared with the control group (74.2% vs. 9.0%, P < 0.001). The TMF group demonstrated more pronounced reductions in HBV DNA (−2.63 vs. −0.22 log10 IU/mL, P < 0.001), HBsAg (−0.07 vs. −0.04 log10 IU/mL, P = 0.02), and ALT levels (−14.09% vs. 0%, P = 0.003) compared with the blank control. In the TMF group, the proportion of participants with high-normal ALT levels (20–40 IU/L) was reduced. No significant differences were observed between the groups in creatinine, glomerular filtration rate, bone turnover biomarkers, lipid profiles, or phosphorus levels.

TMF treatment demonstrates significant efficacy in chronic HBV-infected patients with normal ALT levels and shows a favorable safety profile regarding bone, renal, and lipid parameters. The PROMOTE study is ongoing, and further results at 96 and 144 weeks are expected to provide additional insights.

Type 2 diabetes (T2D) is a metabolic disorder characterized by insulin resistance (IR), inflammation, and dysregulation in glucose metabolism. The disease is spreading globally, partly due to aging, which can damage the immune system and speed up the progression of the metabolic disorder. This review primarily delves into the triggers for T2D within the framework of the ominous octet, which emphasizes 8 principal factors under the “ominous octet” framework that contribute to high blood glucose and associated metabolic disorders. The article studies the interplay of hyperinsulinemia, mitochondrial dysfunction (MD), and endoplasmic reticulum (ER) stress with immune aging in driving disease progression affecting each component of the octet. MD and ER stress can result in defects in insulin signaling, ultimately leading to β-cell death. Chronic inflammation associated with aging, also known as inflammaging, especially affects older adults by worsening IR and glucose regulation, which creates a continuous sequence of metabolic problems. Thus, the “ominous octet” framework provides fundamental knowledge to develop personalized treatment approaches that target metabolic dysfunction together with ER stress, MD, and immune system imbalances. These strategies show promising potential to improve treatments for T2D and may lead to better health outcomes for older adults dealing with this condition.

Leishmaniasis is a dangerous yet neglected tropical disease affecting a vast population of the world. Several medicinal plants and their constituents (natural products/phytochemicals) have been considered of prime importance for the management of leishmaniasis over the years. The present review sheds light on the molecular mechanisms of the constituents obtained from medicinal plants that are pre-clinically effective against leishmaniasis. Various mechanisms by which medicinal plant-derived natural products elicit their action against leishmaniasis are illustrated in the literature. The mechanisms identified include: disruption of cytoplasmic and mitochondrial membranes, induction of apoptosis and autophagy, modulation of gene expression and immunological pathways, pro-oxidant effects (disrupting redox balance) with mitochondrial dysfunction, cell cycle arrest, impaired cellular bioenergetics, i.e., adenosine triphosphate production and coagulation of cellular contents within Leishmania parasites. Future phytochemical and pharmacological (especially clinical) studies are necessary to further understand the mechanistic details of medicinal plant-derived natural compounds and to develop new phytotherapeutic entities from nature against leishmaniasis.

This review presents the latest evidence on the link between genetic single nucleotide polymorphisms and dental caries, highlighting key genes and pathways involved, introducing foundational concepts, and discussing essential methodological considerations for future research. Several genes have been identified as significantly associated with caries experience, including those related to tooth mineral tissues, taste perception, salivary composition and flow, and immune response. Epistatic interactions appear to be crucial in explaining genetic influence. Inconsistencies in the literature are attributed to variations in caries classification, age groups, ethnic backgrounds, limited statistical power, and linkage disequilibrium. Population stratification often confounds results, and few studies adequately control for genetic ancestry. Ensuring Hardy-Weinberg equilibrium and accounting for linkage disequilibrium are essential to avoid bias. Bonferroni corrections for multiple comparisons are fundamental but rarely applied, contributing to inconsistent findings. In conclusion, genetic epidemiology studies suggest that dental caries has a genetic component, accounting for significant individual differences in disease risk.

Atypical teratoid/rhabdoid tumor (AT/RT) is a rare and highly aggressive embryonal tumor that predominantly affects infants and young children. This malignancy arises from primitive neuroectodermal cells and exhibits heterogeneous differentiation into various embryonic tissues. Due to its rarity and complexity, diagnosing and managing AT/RT present significant challenges. Recent studies have summarized the key features of cerebellar and supratentorial AT/RT cases; however, critical gaps remain in understanding their diffuse leptomeningeal variants and long-term functional outcomes. Here, we report a case of a two-year-old child diagnosed with cerebellar AT/RT, who presented with vomiting and gait instability. The patient underwent a gross total resection followed by adjuvant radiotherapy and chemotherapy. Despite achieving radiological remission, the patient survived for only eight months and experienced severe neurological deficits, including persistent ataxia and recurrent infections. This case highlights the disconnect between surgical success and long-term quality of life. It underscores the importance of integrating molecular diagnostics and palliative care to address the multifaceted burden of AT/RT.
