Objectives: Previous studies have reported that serum total bilirubin provides some protection against coronary artery disease (CAD); however, the relationship between serum levels of total bilirubin and culprit/target plaque vulnerability in patients with CAD remains unclear. In this study, we investigated the association between total bilirubin and tissue characterization of coronary plaque in patients with CAD.
Methods: We enrolled 85 consecutive patients with CAD who underwent coronary angiography and intravascular ultrasound analyses [45 with acute coronary syndrome (ACS); 40 with stable angina pectoris (SAP)], and 45 age-matched participants served as the control group. Serum levels of total bilirubin in all participants were measured. The stability of the coronary plaque was compared between the ACS group and the SAP group, and the relationship between serum levels of total bilirubin and the features of coronary plaque was analyzed.
Results: Serum levels of total bilirubin in the ACS group were significantly lower than those in the SAP and control groups (P<0.01). Serum levels of total bilirubin were positively associated with fibrous plaques (r=0.386, P<0.001), whereas they were negatively associated with plaque burden (r=-0.413, P<0.001), lipid plaque (r=-0.419, P<0.001), and remodeling index (r=-0.275, P<0.05). Furthermore, an independent association between serum levels of total bilirubin and lipid-rich plaques (odds ratio, 0.78; 95% confidence interval, 0.64-0.95) was observed.
Conclusion: Serum total bilirubin levels were found to be inversely associated with coronary plaque vulnerability, and decreased serum levels of total bilirubin may be an important factor for coronary lipid plaque formation, which contributes to the pathogenesis of CAD.

The aggregation of proteins, peptides and amino acids has been a keen subject of interest owing to their implications in metabolic disorders. In this work, we investigated the self-aggregation of the unmodified aromatic amino acid l-tryptophan (Trp) into unusual spherical microstructures. Using fluorescence spectroscopy and field emission scanning electron microscopy (FE-SEM), we detail the time-dependent transformation of monomeric tryptophan into spherical aggregates with distinct fluorescence characteristics (λ = 345 nm, λ = 430 nm) compared to the monomer.

Background: In this study, we aimed to evaluate the role of the glucose-to-potassium ratio in predicting in-hospital mortality and prognosis of patients diagnosed with sepsis and septic shock in an emergency department and admitted to an emergency critical intensive care unit (ICU).
Methods: This study was a retrospective and observational evaluation of nontraumatic sepsis and septic shock patients > 18 years of age who were admitted to the emergency department of a tertiary training and research hospital and had available glucose and potassium values at the time of admission. The patients were evaluated over a 24-month period.

Objective: This study aimed to explore the risk factors of hypokalemia after radical resection of esophageal cancer (EC) and establish a nomogram risk prediction model to evaluate hypokalemia risk after esophagectomy. Thus, this study provides a reference for the clinical development of intervention measures.
Methods: Clinical data of EC patients who underwent radical surgery from January 2020 to November 2022 in the First Affiliated Hospital of Guangxi Medical University were retrospectively collected.

Background: Statins, as an important class of lipid-lowering drugs, play a key role in the prevention and treatment of cardiovascular diseases. However, with their widespread use in clinical practice, some adverse events have gradually emerged. In particular, the hepatotoxicity associated with statins use has become one of the clinical concerns that require sufficient attention.
