Acute lung injury (ALI) is a severe inflammatory condition with a high mortality rate, often precipitated by sepsis. The pathophysiology of ALI involves complex mechanisms, including inflammation, oxidative stress, and ferroptosis, a novel form of regulated cell death. This study explores the therapeutic potential of andrographolide (AG), a bioactive compound derived from Andrographis, in mitigating Lipopolysaccharide (LPS)-induced inflammation and ferroptosis.

Pyroptosis exhibits a dual role in cancer: it can both promote tumor development and counteract it by activating immune responses that inhibit tumor evasion and encourage cell death. Current tumor immunotherapy strategies, notably CAR-T cell therapy and immune checkpoint inhibitors (ICIs), alongside the potential of certain traditional Chinese medicinal compounds, highlight the intricate relationship between pyroptosis and cancer immunity.

Specifically, the transplantation of kidneys from genetically engineered pigs into human patients has made significant progress, offering a potential clinical solution to the shortage of human kidney supply. Recent trials involving the transplantation of these modified porcine kidneys into deceased human bodies have underscored the practicality of this approach, advancing the field towards potential clinical applications.

In the authors' previous studies, it was demonstrated that amygdalin ameliorated atherosclerosis by the regulation of Tregs in apolipoprotein E‑deficient (ApoE‑/‑) mice. Therefore, the aim of the present study was to investigate the therapeutic effect of amygdalin on low‑density lipoprotein (LDL) receptor deficient (LDLR‑/‑) mice, and to examine its immune regulatory function by the stimulation of Tregs.

The aim of this study was to examine the protective effects of notoginsenoside R1 (NR1) on the maintenance of podocyte number and foot process architecture via the inhibition of apoptosis, the induction of autophagy and the maintenance pf podocyte biology in target cells. The effects of NR1 on conditionally immortalized human podocytes under high glucose conditions were evaluated by determining the percentage apoptosis, the percentage autophagy and the expression levels of slit diaphragm proteins.

Diabetes was induced by a single injection of STZ, and NR1 was administered daily at a dose of 5 mg/kg (low dose), 10 mg/kg (medium) and 20 mg/kg (high) for 16 weeks in Sprague-Dawley rats. Blood glucose levels, body weight and proteinuria were measured every 4 weeks, starting on the day that the rats received NR1.

The present study aimed to determine the apoptotic effects of mangiferin on A549 human lung adenocarcinoma cells. In vitro studies demonstrated that mangiferin exerted growth‑inhibitory and apoptosis-inducing effects against A549 cells.

Therefore, in this study, we aimed to investigate the therapeutic effect of amygdalin on atherosclerosis of apolipoprotein E deficient (ApoE(-/-)) mice, and to explore its immune regulatory function by stimulation of Tregs.
Methods And Results: To evaluate the anti-atherosclerotic effect of amygdalin and for in vivo Treg expansion/activation analysis, ApoE(-/-) mice received intraperitoneal injections of amygdalin, and this therapy resulted in a comparatively 2-fold decrease in triglyceride (TG), 1.
