Intestinal ischemia/reperfusion (II/R) injury is a common life-threatening complication with high morbidity and mortality. Chebulae Fructus Immaturus, the unripe fruit of Terminalia chebula Retz., also known as “Xiqingguo” or “Tibet Olive” in China, has been widely used in traditional Tibetan medicine throughout history. The phenolic acids’ extract of Chebulae Fructus Immaturus (XQG for short) has exhibited strong antioxidative, anti-inflammation, anti-apoptosis, and antibacterial activities. However, whether XQG can effectively ameliorate II/R injuries remains to be clarified. Our results showed that XQG could effectively alleviate II/R-induced intestinal morphological damage and intestinal barrier injury by decreasing the oxidative stress, inflammatory response, and cell death. Transcriptomic analysis further revealed that the main action mechanism of XQG protecting against II/R injury was involved in activating PPARα and inhibiting the NF-κB-signaling pathway. Our study suggests the potential usage of XQG as a new candidate to alleviate II/R injury.

Article Synopsis
- Indole-3-carboxaldehyde (3-IAld), a compound from tryptophan and gut bacteria, helps protect the intestine from radiation damage, highlighting its potential therapeutic role.
- The study focused on the effects of Bifidobacterium longum (B. longum) and its metabolite 3-IAld in mice experiencing intestinal ischemia/reperfusion (II/R) injury, revealing a decrease in gut microbiota diversity and B. longum after injury.
- Transplanting B. longum improved intestinal health by preserving the gut barrier and reducing inflammation, with 3-IAld showing a protective effect through targeting histone deacetylase 3 (HDAC3) and
Baicalin alleviates intestinal ischemia-reperfusion injury by regulating ferroptosis mediated by nuclear factor E2-related factor 2/Glutathione peroxidase 4 signaling pathway.

Baicalin, a predominant bioactive flavonoid derived from the traditional Chinese medicinal herb Scutellaria baicalensis Georgi, has garnered significant attention. Ferroptosis, a relatively novel form of programmed cell death, implicates critical signaling pathways, notably those involving nuclear factor E2-related factor 2 (Nrf2) and glutathione peroxidase 4 (Gpx4). Consequently, this study aims is to elucidate whether baicalin mitigates intestinal tissue damage by modulating the Nrf2-Gpx4 signaling pathway in the context of intestinal ischemia-reperfusion (II/R) injury, thereby influencing iron deposition.

Objective: Eosinophilic otitis media (EOM) is a chronic eosinophilic inflammatory disease linked to bronchial asthma and nasal polyps. EOM is often accompanied by tympanic membrane perforation. Although the primary treatment, steroid therapy, is generally effective, its efficacy may be limited in advanced cases, particularly those involving significant thickening of the middle ear mucosa.

Systemic inflammatory response syndrome and respiratory distress syndrome can be induced by lung injury caused by intestinal ischemia/reperfusion (II/R). There is no effective medical treatment for II/R-induced lung injury. Studies have shown that asiaticoside (AS) protects against lung injury and ischemia/reperfusion injury in several organs.

Background: Intestinal ischemia-reperfusion (II/R) injury is a common clinical emergency with high morbidity and mortality. Given the absence of efficacious prophylactic and therapeutic interventions and specific drugs, sustained efforts are essential to develop new targeted drugs. Corilagin, a naturally polyphenolic tannic acid widespread in longan, rambutan and many other edible economic crops with medicinal properties in China, is of interest due to its multiple bioactivities, including the potential to mitigate II/R injuries.
