N-acetyl-p-aminophenol (APAP) is an antipyretic analgesic commonly used in clinical practice, and APAP overdose can cause severe liver injury and even death. In recent years, the incidence rate of APAP-induced liver injury (AILI) tends to increase, and it has become the second most common cause of liver transplantation worldwide. Autophagy is a highly conserved catabolic process that removes unwanted cytosolic proteins and organelles through lysosomal degradation to achieve the metabolic needs of cells themselves and the renewal of organelles. A large number of studies have shown that autophagy plays a key role in the pathophysiology of AILI, involving the mechanisms such as APAP protein conjugates, oxidative stress, JNK activation, mitochondrial dysfunction, inflammatory response and apoptosis. This article elaborates on the biological mechanism of autophagy in AILI, in order to provide a theoretical basis for the treatment of AILI and the development of autophagy regulators.

Autoimmune hepatitis (AIH) is a chronic inflammatory liver disease. The pathogenesis of AIH remains unclear, but it is mainly autoimmune injury caused by the breakdown of autoimmune tolerance due to the abnormal activation of the immune system, while the specific molecular mechanism remains unknown. Recent studies have shown that abnormal amino acid metabolism plays an important role in the development and progression of AIH. This article reviews the research advances in amino acid metabolic reprogramming in AIH, in order to provide a theoretical basis for amino acid metabolism as a new target for the clinical diagnosis and treatment of AIH.

ObjectiveWith the development of society and the increasing demand for pregnancy at an advanced age, diminished ovarian reserve (DOR) has attracted wider attention. This disease affects the normal menstruation of women and poses a threat to their mental health. Current research on DOR is still in the initial stage, and advancing research progress in DOR necessitates the construction of effective and clinically relevant animal models. Building on existing literature and integrating the diagnosis criteria of DOR in traditional Chinese medicine (TCM) and Western medicine, this study summarized, analyzed, and evaluated existing models, providing a reference for optimizing DOR animal models. MethodsA retrospective analysis of literature on DOR-related animal models was conducted, and the diagnostic criteria of DOR in TCM and Western medicine were sorted out. By means of evaluation methods of animal models, the clinical relevance of each model to TCM and Western medicine was assessed. ResultsDOR animal models included those based on natural factors, iatrogenic factors, immune factors, metabolic factors, and environmental factors. Among them, the model based on iatrogenic factors, especially models induced by Tripterygium wilfordii preparations, cyclophosphamide, and cisplatin, had a high degree of relevance to both Western medical diseases and TCM syndromes and was confirmed as the optimal modeling method for studying DOR at present. ConclusionThe existing DOR modeling methods mostly have a high degree of clinical relevance to Western medical diseases, while the number of DOR animal models with clear TCM syndromes is very limited. TCM plays an indispensable role in exploring DOR treatment methods. Therefore, the development of DOR animal models related to TCM syndromes should be strengthened, further exploring the potential of TCM and providing strong theoretical support for the application of TCM in DOR treatment.

Objective To investigate the species of ticks in Suizhou City, Hubei Province, so as to provide insights into management of ticks and tick-borne diseases. Methods During the period between May 2023 and June 2024, livestock breeding farms and vegetation neighboring the place of residence of confirmed and suspected patients with tick-borne disease were selected as sampling points in rural areas from Yindian Township, Gaocheng Township, Wanhe Township, Wushan Township, Xiaolin Township, Xihe Township, Hedian Township and Beijiao Street in Suizhou City, Hubei Province, where confirmed and suspected cases with tick-borne diseases had been reported. The parasitic ticks on the body surface of free-range livestock were captured with tweezers in livestock breeding farms, and free ticks on the vegetation surface were captured with the flagging method. Morphological identification of tick samples was performed under a microscope, and the gender and developmental stage of ticks were determined. One engorged adult tick, 2 to 3 blood-feeding but non-engorged adult ticks, 10 to 15 unfed female ticks, 15 to 20 unfed male ticks, and 30 to 40 tick nymphs or larvae were assigned into a group, respectively. Genomic DNA was extracted from tick samples in each group, and mitochondrial 16S rRNA gene was amplified. Sequence analysis was performed with the DNASTAR software, and phylogenetic analysis was performed using the software MEGA 7.0. In addition, the phylogenetic tree was generated using the maximum likelihood method based on the Kimura 2 parameter model. Results A total of 2 438 ticks were captured from Suizhou City, Hubei Province during the period between May 2023 and June 2024, including 595 free ticks and 1 483 parasitic ticks. Three developmental stages of ticks were captured, including larvae, nymphs, and adults, and 75.18% (1 899/2 438) of captured ticks were adult, in which 79.04% (1 501/1 899) were female. Morphological and molecular biological assays identified one family, three genera and four species of captured ticks, including 2 425 Haemaphysalis longicornis ticks (99.47%) and one H. flava tick (0.04%) of the genus Haemaphysalis, 11 Rhipicephalus microplus ticks (0.45%) of the genus Rhipicephalus, and one Ixodes sinensis tick (0.04%) of the genus Ixodes in the family Ixodidae. Phylogenetic analysis revealed that the H. longicornis sequence (SZ49) in this study was clustered with sequences from Yunnan Province (GenBank accession number: MH024510.1), Hebei Province (GenBank accession number: MK450606.1) and Henan Province (GenBank accession number: MZ230645.1) into a clade, and the H. flava sequence (SZ19) in this study was clustered with sequences from Japan (GenBank accession number: MW064044.1), South Korea (GenBank accession number: ON629585.1), and Jiangsu Province (GenBank accession number: PP494741.1) and Hebei Province of China (GenBank accession number: MH520685.1) into a clade, while the R. microplus sequence (SZ8) in this study was clustered with the sequences from India (GenBank accession number: MK621328.1), and Henan Province (GenBank accession number: MT555307.1) and Guizhou Province of China (GenBank accession number: PP446801.1) into a clade. The sequence of I. sinensis (SZ23) in this study had 99.51% homology with that (GenBank accession number: OM368265.1) of ticks sampled from Wuhan City, Hubei Province. Conclusion There are four tick species of H. longicornis, H. flava, R. microplus and I. sinensis in Suizhou City, Hubei Province, and H. longicornis is the dominant species. H. flava is firstly recorded in Suizhou City.

Chinese Journal of School Health 2025;46(8):1194-1197
Objective:
To investigate the distribution of pupil diameter and its association with myopia in school age children, providing ideas into the mechanisms of the role of pupil diameter in the onset and development of myopia.
Methods:
Adopting a combination of stratified cluster random sampling and convenience sampling method, 3 839 children from six schools in Shandong Province were included in September 2021. Pupil diameters distribution was analyzed by age, sex, and myopic status. Pearson correlation analysis was used to assess the relationship between pupil diameter and cycloplegic spherical equivalent (SE), as well as axial length (AL) and other variables. Propensity score matching (PSM) was applied to match myopic and non myopic children at a 1∶1 ratio based on age and sex. A generalized linear model (GLM) was constructed with pupil diameter as the dependent variable to identify independent factors influencing pupil size and its association with myopia.
Results:
The mean pupil diameter of school age children was (5.77±0.80)mm. Pupil diameter exhibited a significant increasing trend with age ( F =49.34, P trend < 0.01). Myopic children had a significantly larger mean pupil diameter [(6.10±0.73)mm] compared to non myopic children [(5.62±0.79)mm] with a statistically significant difference( t=18.10, P <0.01). Multivariable GLM analysis, adjusted for age, amplitude of accommodation, and uncorrected visual acuity, revealed a negative correlation between pupil diameter and cycloplegic SE (before PSM: β =-0.089, after PSM: β =-0.063, both P <0.01).
Conclusions
Myopic school age children exhibite larger pupil diameters than their non myopic counterparts. Pupil diameter may serve as a potential indicator for monitoring myopia development in school age children.

ObjectiveTo investigate the effect and mechanism of Dendrobium mixture (DMix)-containing serum on high glucose-induced podocyte injury in mice. MethodThe MPC5 mouse glomerular podocytes were cultured in vitro, and the optimal glucose concentration for modeling, modeling time, and concentration of DMix-containing serum for administration were determined. The cells were classified into normal (5.5 mmol·L-1 glucose+10% blank serum), model (30 mmol·L-1 glucose+10% blank serum), DMix-containing serum (30 mmol·L-1 glucose+10% DMix-containing serum), ferroptosis inhibitor (Fer-1, 30 mmol·L-1 glucose+10% blank serum+1 μmol·L-1 Fer-1) groups. The corresponding kits were used to measure the levels of Fe2+ and lactate dehydrogenase (LDH) in cells. Enzyme-linked immunosorbent assay was employed to determine the content of glutathione (GSH) and lipid peroxide (LPO) in cells. Fluorescence probe was used to measure the reactive oxygen species (ROS) level. Real-time fluorescence quantitative polymerase chain reaction and Western blotting were employed to determine the mRNA and protein levels, respectively, of Wilms' tumor-1 (WT-1), desmin, long chain acyl-CoA synthase 4 (ACSL4), and glutathione peroxidase 4 (GPX4) in podocytes. ResultCompared with the blank group, the intervention with 30 mmol·L-1 glucose for 48 h reduced podocyte viability (P<0.01), and the 10% DMix-containing serum showed the most significant improvement in podocyte viability (P<0.01). Compared with the normal group, the model group presented elevated levels of Fe2+, LDH, LPO, and ROS, lowered GSH level, up-regulated mRNA and protein levels of desmin and ACSL4, and down-regulated mRNA and protein levels of WT-1 and GPX4 (P<0.01). Compared with the model group, the DMix-containing serum lowered the Fe2+, LDH, LPO, and ROS levels, elevated the GSH level, down-regulated the mRNA and protein levels of desmin and ACSL4, and up-regulated the mRNA and protein levels of WT-1 and GPX4 in podocytes (P<0.05, P<0.01). ConclusionDMix-containing serum exerts a protective effect on high glucose-induced podocyte injury by inhibiting ferroptosis.

ObjectiveTo investigate the attenuating effect of Dioscoreae Bulbiferae Rhizoma(DBR) processed with Phaseoli Radiati Semen(PRS) juice, and explore the attenuating mechanism based on ferroptosis of the main toxic target organ. MethodSixty male ICR mice were randomly divided into blank group, DBR group, water roasted DBR group(hereinafter referred to as water group), PRS juice-roasted DBR group 1(DBR-PRS 10∶1, stuffy moistening for 40 min, stir-fried at 130 ℃ for 18 min, hereinafter referred to as group 1), PRS juice-roasted DBR group 2(DBR-PRS 10∶1, stuffy moistening for 80 min, stir-fried at 100 ℃ for 14 min, hereinafter referred to as group 2), PRS juice-roasted DBR group 3(DBR-PRS=20∶3, stuffy moistening for 40 min, stir-fried at 160 ℃ for 14 min, hereinafter referred to as group 3). The raw and processed groups of DBR were gavaged with their corresponding 95% ethanol extract at a dose of 3 g·kg-1·d-1, while the blank group was gavaged with an equal volume of 0.5% sodium carboxymethyl cellulose, once a day for 14 consecutive days. Hematoxylin-eosin(HE) staining was used to observe the histopathological changes of mouse liver. Alanine aminotransferase(ALT) and aspartate aminotransferase(AST) levels in serum, as well as malondialdehyde(MDA), ferrous ions(Fe2+), reduced glutathione(GSH) and superoxide dismutase(SOD) levels in liver tissue were detected by the biochemical detection. Western blot was used to detect the expression of iron key proteins such as ferritin heavy chain 1(FTH1) and glutathione peroxidase 4(GPX4). ResultHE staining results showed that the liver tissue structure of the blank group was clear, the morphology of hepatocytes was normal, the cytoplasms of hepatocytes in the DBR group and water group were loose and vacuolar, with obvious pathological damages, and the pathologic damages of mice in the group 1-3 were significantly improved. Compared with the blank group, the levels of ALT, AST, MDA and Fe2+ in mice from the DBR group were significantly increased(P<0.01), while GSH and SOD levels were significantly reduced(P<0.01), and the protein expression levels of FTH1 and GPX4 were significantly decreased(P<0.01). Compared with the DBR group, the ALT, AST,MDA and Fe2+ levels of mice in the group 1-3 were significantly reduced(P<0.05, P<0.01), the GSH and SOD levels and the protein expression levels of FTH1 and GPX4 were significantly increased(P<0.01). Compared with the water group, the AST and MDA levels of mice in the group 1-3 were significantly reduced(P<0.05, P<0.01), the SOD level significantly increased(P<0.05, P<0.01), the FTH1 protein expression significantly increased(P<0.01), and the serum ALT level of mice in the group 2-3 significantly reduce(P<0.01), Fe2+ level significantly reduced(P<0.01), GSH level significantly increased(P<0.05, P<0.01), and GPX4 protein expression significantly increased(P<0.05, P<0.01). Among the group 1-3, the group 3 had the best detoxification effect. ConclutionProcessing with PRS juice can reduce the liver injury induced by DBR, and the mechanism may be related to the inhibition of ferroptosis in the liver.
