Abstract
Everolimus, a known inhibitor of the mammalian target of rapamycin (mTOR), has shown uncertain efficacy in treating hepatoblastoma. This study delves into the potential anti-hepatoblastoma properties of everolimus and its intricate relationship with autophagy and ferroptosis, both in vitro and in vivo. In vivo, tumor tissue from hepatoblastoma patient and human hepatoblastoma cell line HuH-6 were xenografted into nude mice to establish xenograft models for observing the effect of everolimus on tumor growth. In vitro, HuH-6 cells were cultured to evaluate the anti-hepatoblastoma activity of everolimus. Transmission electron microscopy and microtubule-associated proteins 1 light chain 3 (LC3), beclin 1, and p62 protein expressions were employed to investigate autophagy. Additionally, indicators of cell apoptosis, reactive oxygen species (ROS) and proteins associated with ferroptosis were measured to evaluate ferroptosis. The results demonstrate that everolimus treatment effectively induced the formation of autophagosomes in hepatoblastoma cells, upregulated the LC3II/I ratio and beclin 1 expression, and downregulated p62 expression, indicating an enhanced autophagy level both in vitro and in vivo. Furthermore, everolimus treatment induced cell apoptosis, increased ROS level, elevated concentrations of malondialdehyde, 4-hydroxynonenal, and iron content, while reducing the ratio of glutathione/oxidized glutathione, and downregulating the protein expression of glutathione peroxidase 4 and solute carrier family 7 member 11, suggesting its ability to induce ferroptosis in hepatoblastoma cells. Importantly, the induction of ferroptosis by everolimus was significantly reversed in the presence of autophinib, an autophagy inhibitor, indicating the autophagy-dependent of everolimus-induced ferroptosis. Taken together, these findings suggest that everolimus holds promise as an effective anti-hepatoblastoma drug, with its mechanism of action potentially involving the induction of autophagy-dependent ferroptosis in hepatoblastoma cells.

Abstract
The study was aimed to analyze the seasonal pollen allergen spectrum of patients with allergic rhinitis (AR) in Nanchang city, and to provide evidence for improving the clinical diagnosis, treatment, prevention and epidemiology of seasonal AR. A retrospective analysis was conducted on the results of skin prick test (SPT) among 1 752 patients with AR in outpatient at Department of Otolaryngology, the First Affiliated Hospital of Nanchang University from September 2020 to August 2021 (a total of 1 069 males and 683 females, age ranged from 2 to 84 years old). SPSS 22.0 software was used to analyze the positive rates of main allergens and their differences in gender, age, and month of visit. Differences among groups were compared by student t test, Wilcox rank sum test, or χ2 test. The results showed that among 1 752 SPT-positive patients, the number of simple seasonal AR and the number of perennial combined seasonal AR were 102 (5.82%) and 281 (16.04%), respectively. There was no significant difference between male and female patients in positive seasonal pollen allergens (χ2=2.181, P>0.05), but the positive rate of indoor seasonal pollen allergens in males was higher than that in females (χ2=7.901, P<0.05). The seasonal pollen allergens ranking top 5 of the positive rates were willow (6.62%, 116/1 752), humulus scandens (5.71%, 100/1 752), rape (5.54%, 97/1 752), grey pigweed (4.62%, 81/1 752) and birch (3.60%, 63/1 752). The positive rates of indoor and seasonal pollen allergens increased first and then decreased in different age groups, and the highest positive rates of seasonal pollen allergens were in the age group of 31-40 years old, with statistical significance compared with other groups (χ2=61.269, P<0.05). The seasonal allergen positive rate showed two peaks in time: March to May and September to November. The positive rate of pollen in spring was 60.27% (132/219), which was significantly higher than that in autumn (39.73%,87/219) (χ2=9.247, P<0.05). The positive rate of pollen combination in spring and autumn was 68.29% (112/164), which was significantly higher than that in spring and autumn alone (18.9%,31/164) and (12.8%, 21/164) (χ2=14.731, P<0.05). In summary, pollen allergy in Nanchang City cannot be ignored, accounting for more than 20% of the total number of AR. The incidence of seasonal AR in Nanchang City showed two peaks (March to May and September to November). The common allergens for seasonal AR in Nanchang City were willow, humulus scandens, rape, grey chenopods and birch.

Abstract
Glucagon-like peptide-1 (GLP-1), an incretin hormone primarily secreted by intestinal L cells, regulates glucose metabolism by increasing insulin synthesis and secretion, decreasing plasma glucagon levels, reducing food intake, and slowing gastric emptying. This has led to the development of GLP-1 receptor (GLP-1R) agonists as a treatment for diabetes and obesity. In addition to being present in beta cells, GLP-1R has also been identified in blood vessels and the heart, suggesting that GLP-1R agonists may have an impact on cardiovascular health. There is now substantial evidence supporting GLP-1's protective effects on the cardiovascular system. This review summarizes the current research on GLP-1-based therapy for coronary artery disease (CAD) by examining its protective effects against inflammation and ischemia/reperfusion injury and analyzing clinical trials on GLP-1-based therapies for CAD. Although results from various studies were inconsistent, the challenge of transitioning GLP-1-based therapies from the laboratory to the clinical setting remains. Further well-designed and high-quality studies are necessary to determine the efficacy and safety of GLP-1 for patients with CAD.

Abstract
Objective To observe the efficacy and prognosis of low-temperature plasma ablation + drug therapy in the treatment of fungal corneal ulcers. Methods The present paper presents a retrospective clinical study with a subject base of 34 eyes. Patients with a fungal corneal ulcer who visited the Affiliated Eye Hospital of Nanchang University between August 2019 and December 2021 were selected as the study participants. They were found to have highly reflective fungal hyphae in the corneal stroma layer via confocal microscope examination, which were revealed to be positive on etiology examination, with the ulcer and infiltration depths ≤1/2 of the corneal thickness. The efficacy and prognosis were observed after treatment with low-temperature plasma ablation + drug therapy. Results A total of 34 cases (34 eyes) had clinical manifestations of corneal infiltration and corneal ulcer formation, with a corneal lesion diameter of 1.31-8.64 mm (average = 4.79 ± 2.03 mm). The average healing time of corneal ulcers was 6.2 ± 1.7 days. Among a total of 34 cases (34 eyes) in patients with fungal keratitis, the infection was controlled and the ulcers gradually healed after treatment with low-temperature plasma system + drug therapy in a total of 30 cases (30 eyes, 88%). A total of three cases (3 eyes, 9%) exhibited no clear improvement after the treatment, and the patients underwent conjunctival flap covering surgery. One case (one eye, 3%) exhibited no clear improvement after further treatment, with the patient experiencing corneal perforation and ultimately undergoing penetrating keratoplasty. Conclusion Low-temperature plasma ablation + drug therapy can effectively control the progression of fungal keratitis infection, as well as significantly shorten the ulcer healing time, and is, therefore, an effective method.
