ObjectiveTo compare the effects of different formulations of Yinqiao Powder (银翘散, YP) on inflammation and immune function in a rat model of acute pharyngitis induced by ammonia water. MethodsA rat model of acute pharyngitis was established by spraying 15% ammonia water into the pharynx of male SD rats using a laryngeal atomizer twice daily (three sprays each time) for three consecutive days. Successfully modeled rats were randomly divided into 5 groups, including a model group (normal saline, 10 ml/kg), YP decoction group (10.73 g/kg), YP granule group (10.73 g/kg), cydiodine group (0.39 mg/kg) and blank control group (normal saline, 10 ml/kg), with 12 rats in each group. All groups received intragastric administration once daily for 10 consecutive days. After the final gavage administration, frequency of back arching per minute, frequency of vibrissae grooming per minute, and grooming episodes per five minutes were recorded in rats. The cumulative body weight change was calculated as the difference in body weight between day 10 and day 1 of gavage administration. Behavioral observations were performed using the open field test, and the total distance traveled was recorded. After sample collection, the lung index and thymus index were calculated. Histopathological changes in the pharyngeal and tracheal tissues were observed using HE staining. Serum inflammatory markers including eosinophil cationic protein (ECP), angiotensin-converting enzyme 2 (ACE2), and C-reactive protein (CRP), as well as immune parameters including immunoglobulin M (IgM), immunoglobulin A (IgA), immunoglobulin G (IgG), CD4, CD4/CD8 ratio, and CD8 were measured by ELISA. In addition, ELISA was used to determine the levels of inflammatory mediators in pharyngeal tissues, including phospholipase A2 (PLA2), cyclooxygenase-1 (COX-1), cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE2), vascular cell adhesion molecule-1 (VCAM-1), C-X-C motif chemokine ligand 1 (CXCL1), vascular endothelial growth factor (VEGF), and matrix metalloproteinase-9 (MMP-9). ResultsCompared to the blank control group, the model group exhibited significantly increased frequencies of back arching per minute, vibrissae grooming per minute, and grooming episodes per five minutes, and lung index, and decreased cumulative body weight change, thymus index, and total distance traveled, as well as elevated serum levels of ECP, ACE2, and CD8, reduced levels of IgM, IgA, IgG, CD4, and CD4/CD8 ratio, and increased levels of PLA, COX-1, COX-2, PGE2, VCAM-1, CXCL1, VEGF, and MMP-9 in pharyngeal tissues (P<0.05). Histopathological examination revealed keratinization of the superficial epithelial layer of the pharyngeal mucosa, accompanied by congestion and edema in the lamina propria and infiltration of inflammatory cells; in the tracheal mucosa, extensive inflammatory cell infiltration, ciliary disruption, and goblet cell damage were observed. Compared to the model group, except for CRP, IgG, and CD4, all above mentioned indicators were improved in the YP granule group, YP decoction group, and cydiodine group (P<0.05). Histopathological lesions in the pharyngeal and tracheal tissues were also alleviated. Compared to the YP decoction group, rats in the YP granule group exhibited decreased frequencies of back arching per minute, vibrissae grooming per minute, and grooming episodes per five minutes, as well as reduced serum ECP levels. Meanwhile, the cumulative body weight gain and serum levels of IgM, IgA, IgG, and CD4/CD8 increased, whereas CD8 levels decreased (P<0.05). ConclusionYP can effectively alleviate symptoms of acute pharyngitis in a rat model, improve inflammatory responses and immune-related indicators, demonstrating superior therapeutic effects in the dosage form of granule.

Hepatic ischemia-reperfusion injury (HIRI) has been considered as an inevitable process of liver transplantation. Hepatocyte ferroptosis is a key factor in HIRI development, yet precise mechanism and potential therapies are still unclear. Here, we demonstrated a strong correlation between hepatocyte ferroptosis and the downregulation of poly(rC)-binding protein (PCBP2), which compromised the stability of antiporter system Xc- (consisted of SL3A2/SLC7A11). Besides, inhibiting PCBP2 contributed to facilitating cofactor p300 to enhance the transcriptional activity of HIF1α, leading to the expression and secretion of HMGB1. Then, released HMGB1 from ferroptotic hepatocytes worsened M1 macrophage recruitment and immune response during HIRI. Additionally, acteoside (ACT) was shown to assist PCBP2 in stabilizing the mRNA stability of Slc3a2 and Slc7a11, as well as enhance the binding affinity of PCBP2-system Xc-. Beyond that, ACT also supported PCBP2 to limit HMGB1-induced M1 macrophage recruitment through imposing restrictions on p300 and HIF1α. Furthermore, specific knockdown of PCBP2 in hepatocytes directly interposed the therapeutic efficacy of ACT on HIRI mice. In conclusion, ACT alleviated hepatocyte ferroptosis and HIRI via promoting PCBP2 to maintain the stability of system Xc- and limit HIF1α/p300-HMGB1 signaling. These findings highlight the therapeutic benefits of ACT in treating HIRI and offer insights into innovative therapeutic strategies.

Pulpitis is a prevalent inflammatory disease in dentistry, and root canal therapy remains the primary clinical treatment for it. However, pulp removal leads to reduced tooth fracture resistance and complications such as secondary infection and tooth fracture. As a potential alternative, vital pulp therapy (VPT) relies on precise assessment of pulp status; yet current clinical diagnostic methods lack specificity. The establishment of appropriate animal models for pulpitis is crucial for investigating its pathogenesis, developing specific diagnostic biomarkers, and optimizing VPT strategies. This review systematically summarizes experimental animals selection based on anatomical compatibility and pathological similarity, as well as model construction methods and multimodal evaluation systems for pulpitis animal models, aiming to provide insights for related researches.
