BACKGROUND:
Arsenic trioxide (ATO) is indicated as a broad-spectrum medicine for a variety of diseases, including cancer and cardiac disease. While the role of ATO in hepatic ischemia/reperfusion injury (HIRI) has not been reported. Thus, the purpose of this study was to identify the effects of ATO on HIRI.
METHODS:
In the present study, we established a 70% hepatic warm I/R injury and partial hepatectomy (30% resection) animal models in vivo and hepatocytes anoxia/reoxygenation (A/R) models in vitro with ATO pretreatment and further assessed liver function by histopathologic changes, enzyme-linked immunosorbent assay, cell counting kit-8, and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL) assay. Small interfering RNA (siRNA) for extracellular signal-regulated kinase (ERK) 1/2 was transfected to evaluate the role of ERK1/2 pathway during HIRI, followed by ATO pretreatment. The dynamic process of autophagic flux and numbers of autophagosomes were detected by green fluorescent protein-monomeric red fluorescent protein-LC3 (GFP-mRFP-LC3) staining and transmission electron microscopy.
RESULTS:
A low dose of ATO (0.75 μmol/L in vitro and 1 mg/kg in vivo ) significantly reduced tissue necrosis, inflammatory infiltration, and hepatocyte apoptosis during the process of hepatic I/R. Meanwhile, ATO obviously promoted the ability of cell proliferation and liver regeneration. Mechanistically, in vitro studies have shown that nontoxic concentrations of ATO can activate both ERK and phosphoinositide 3-kinase-serine/threonine kinase (PI3K-AKT) pathways and further induce autophagy. The hepatoprotective mechanism of ATO, at least in part, relies on the effects of ATO on the activation of autophagy, which is ERK-dependent.
CONCLUSION
Low, non-toxic doses of ATO can activate ERK/PI3K-AKT pathways and induce ERK-dependent autophagy in hepatocytes, protecting liver against I/R injury and accelerating hepatocyte regeneration after partial hepatectomy.

Allergen-specific immunotherapy(AIT) remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis(AR). Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group(CRRCG) convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Journal of Preventive Medicine 2024;36(1):26-29, 33
Objective :
To examine the causal relationship between ulcerative colitis (UC) and pancreatitis, to provide basis for early screening of pancreatitis among UC patients.
Methods:
Genomic data of UC were obtained from 47 745 European individuals pooled by the International Inflammatory Bowel Disease Genetics Consortium, including 156 116 single nucleotide polymorphism (SNP), and genomic data of pancreatitis were obtained from 198 166 European individuals pooled from FinnGen, including 16 380 428 SNPs. Mendelian randomization (MR) analysis was performed using the inverse variance weighted (IVW) method with 72 UC-associated SNPs as instrumental variables and pancreatitis as the study outcome. The heterogeneity was assessed using Cochran Q test, the horizontal pleiotropy was assessed using MR-Egger regression, MR-PRESSO was performed with the exclusion of outliers, and effect of individual SNP on the results was tested with the leave-one-out method.
Results:
MR analysis results showed that patients with genetically predicted UC had an increased risk of pancreatitis relative to those without UC (OR=1.076, 95%CI: 1.019-1.136, P<0.05). Cochran Q test showed no heterogeneity (P>0.05), and MR-Egger regression did not reveal horizontal pleiotropy of instrumental variables (P>0.05). The MR analysis results were robust after removing SNP one by one.
Conclusions
Genetically predicted UC is associated with an increased risk of pancreatitis. The screening for pancreatitis risk should be enhanced in patients with UC.

OBJECTIVE To explore the effects and potential mechanism of evodiamine on inflammatory response and apoptosis of epithelial cells in asthma model rats. METHODS SD rats were separated into control group, model group, evodiamine low-dose group (10 mg/kg), evodiamine high-dose group (20 mg/kg), dexamethasone group (positive control, 0.5 mg/kg), epidermal growth factor (EGF) group [mitogen-activated protein kinase (MAPK) activator, 10 μg], evodiamine high-dose+EGF group (20 mg/kg evodiamine+10 μg EGF), with 10 rats in each group. Except for the control group, the other groups were sensitized by 3-point injection of 10% ovalbumin(OVA)-aluminium hydroxide mixture and stimulated by inhalation of 2%OVA nebulized liquid to establish an asthma model. The count of inflammatory cells (macrophages and lymphocytes) in bronchoalveolar lavage fluid (BALF) was detected in each group; pathological changes of lung tissue in rats were observed; the apoptosis of airway epithelial cells, the levels of serum inflammatory factors [tumor necrosis factor-α, interleukin-6 (IL-6) and IL-4], the expressions of pathway-related proteins p38 MAPK, phosphorylated p38 MAPK (p-p38 MAPK), signal transduction and transcription activating factor 1 (STAT1)] and apoptosis-related proteins [B cell lymphoma-2 (Bcl-2) and Bcl-2 associated X protein (Bax)] were all detected in lung tissue. RESULTS Compared with the control group, bronchial mucosal edema, thickening of alveolar septa and extensive infiltration of inflammatory cells were observed in the lung tissue of rats in the model group; the number of inflammatory cells, apoptosis rate of airway epithelial cells, the levels of inflammatory factors, p-38 MAPK/p-38 MAPK, and the protein expressions of Bax and STAT1 were increased significantly; the expressions of Bcl-2 protein and Bcl-2/Bax were reduced significantly (P<0.05). Compared with the model group, the pathological changes in lung tissues were alleviated to varying degrees in evodiamine low-dose and high-dose groups, and dexamethasone groups, and the above indicators were significantly reversed. However, the change trends of corresponding indicators in the EGF group were opposite to the above (P<0.05). EGF could significantly attenuate the effect of high-dose evodiamine on inflammatory response in asthmatic rats (P<0.05). CONCLUSIONS Evodiamine can relieve inflammatory reactions and inhibit the apoptosis of airway epithelial cells in asthmatic rats, the mechanism of which may be associated with inhibiting p38 MAPK/STAT1 signaling pathway.
