We investigated ICAM-1/CD54 tissue immunoreactivity and serum levels of its soluble form (sICAM-1) in patients with Hodgkin's disease (HD) at diagnosis. ICAM-1 was strongly expressed in involved tissues, and sICAM-1 serum levels were higher in HD (79 patients) than in controls (P < 0.01), and in patients with more advanced or more active disease (stages III + IV vI + II: P = 0.002; stage 'B' v 'A': P < 0.0001; 'bulky' disease v non-'bulky': P = 0.042). We suggest that tissue ICAM-1 overexpression leading to increase of circulating sICAM-1 may interfere with the lymphocyte adhesion machinery thus contributing to the well-known immune derangement of HD.

The immunogenicity of rabies vaccines is commonly measured by serological testing, which includes measuring rabies virus-neutralising antibody titre levels in the serum. Apart from humoral immunity, cellular immunity measurements are also helpful in assessing the immunogenicity and efficacy of rabies vaccinations. Recently, there has been an increased emphasis on cellular immunity measurements against rabies in humans and animals.

Background: Bear bile powder (BBP), a unique animal-derived medicine with anti-inflammatory and antioxidant effects, is used in Shexiang Tongxin dropping pills (STDP), which is applied to treat cardiovascular diseases, including acute myocardial infarction (AMI). The efficacy and compatibility mechanisms of action of BBP in STDP against cardiovascular diseases remain unclear. This study aimed to investigate the compatibility effects of BBP in STDP in rats with AMI.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.
