ObjectiveTo investigate the protective effect of liver-targeted fibroblast growth factor 21 (FGF21) overexpression against CCl₄-induced acute liver injury (ALI) and its association with silent information regulator 1/glutathione peroxidase 4 (SIRT1/GPX4) expression and ferroptosis-related markers. MethodsFemale ICR mice (8 weeks old) were randomly divided into Control, CCl₄, adeno-associated virus (AAV)-FGF21, and AAV-FGF21 + CCl4 groups. Liver-targeted FGF21 overexpression was achieved via tail vein injection of AAV8-FGF21 virus with green fluorescent protein (GFP) labeling. ALI was induced by intraperitoneal injection of CCl₄ (0.3 mL/kg), with sample collection at 12 hours. Body weight and liver weight were recorded to calculate the liver weight/body weight. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were measured using a biochemical analyzer. FGF21 expression in liver tissues was detected by immunofluorescence. Hepatic histopathology was evaluated by HE staining. RT-qPCR was performed to assess mRNA expression of ferroptosis and iron metabolism-related genes (ACSL4, PTGS2, HJV, FPN, GPX4), FGF21, and SIRT1. Protein expression of FGF21, SIRT1, and GPX4 were determined by Western blot. Iron content, malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) activity in liver homogenate were quantified using assay kits. ResultsCompared with the Control group, the FGF21 mRNA and protein expression elevated in CCl4 group; serum ALT/AST levels and liver weight/body weigh increased. The HE staining results showed that the liver cell membranes were ruptured. The mRNA levels of ACSL4 and PTGS2, the iron content and MDA levels all increased (P<0.01). The mRNA levels of SIRT1, GPX4, HJV, and FPN, the GSH level and SOD activity all decreased (P<0.05), and the protein levels of SIRT1 and GPX4 both decreased (P<0.05). Compared with the CCl4 group, the serum levels of ALT and AST in the AAV-FGF21 + CCl4 group were decreased (P<0.01), and the liver/body ratio of mice decreased (P<0.01). The results of HE staining showed that the degree of liver injury was alleviated. The mRNA levels of ACSL4 and PTGS2, iron content and MDA level all decreased (P<0.01), while the mRNA levels of SIRT1, GPX4, HJV, FPN, GSH level and SOD activity all increased (P<0.05). The protein levels of SIRT1 and GPX4 both increased (P<0.05). ConclusionFGF21 overexpression is associated with enhanced SIRT1/GPX4 expression and suppression of ferroptosis features, thereby contributing to the alleviation of CCl4-induced ALI.

Objective:To explore the characteristics of serum galactose-deficient IgA1 (Gd-IgA1) and Gd-IgA1/IgA ratio in normal children.Methods:The children from a kindergarten and 3 primary or secondary schools in Baoding (Hebei Province) from March to August 2023 were included in the cross-sectional study.According to their age, the children were divided into the 3-6-year-old group, >6-11-year-old group, and >11-16-year-old group.Besides, some adults were also included as the control group.The immunoturbidimetric assay was used to detect serum IgA levels, and the enzyme-linked immunosorbent assay (ELISA) was employed to detect Gd-IgA1 and Gd-IgA1/IgA levels.The above indicators were subject to normal distribution tests and analysis of variance (ANOVA)or rank sum test.Results:A total of 136 normal subjects were included for analysis.Among these subjects, there were 64 males and 72 females.There were 13 children in the 3-6-year-old group, 51 children in the >6-11-year-old group, and 56 children in the >11-16-year-old group.Besides, 16 normal adults (28-45 years old) from the physical examination center were also included as the control group.The serum IgA levels of the 3-6-year-old group, >6-11-year-old group, >11-16-year-old group, and adult group were (0.88±0.35) g/L, (1.38±0.65) g/L, (1.78±0.61) g/L, and (2.49±0.94) g/L, respectively.Except for no statistically significant difference between the 3-6-year-old group and the >6-11-year-old group, as well as between the >11-16-year-old group and the adult group, all other age groups showed statistically significant differences in serum IgA levels (all P<0.05).The serum Gd-IgA1 levels of the 3-6-year-old group, >6-11-year-old group, >11-16-year-old group, and adult group were 7.77(5.77, 16.51) μg/L, 7.12(5.29, 9.82) μg/L, 8.96(6.21, 14.30) μg/L, and 9.39(6.63, 40.00) μg/L, respectively, with statistically significant differences ( H=9.22, P=0.027).There was no significant difference in the Gd-IgA1/IgA ratio among different groups ( P=0.130).The correlation analysis suggested that Gd-IgA1/IgA1 did not correlate with age ( r=0.134, P=1.200).The Gd-IgA1 level was positively correlated with the IgA level ( r=0.204, P=0.017).There was no significant difference in serum IgA, Gd-IgA1, and Gd-IgA1/IgA levels between different gender groups. Conclusions:There are differences in Gd-IgA1 levels among different age groups among these children, but Gd-IgA1/IgA is not correlated with age.As a diagnostic biomarker, Gd-IgA1 should be emphasized from the different levels among different age groups, while Gd-IgA1/IgA seems to be more convenient for clinical research and application.

Objective:To investigate the role of YTHDF2 in cervical lesions and its potential molecular mechanism.Methods:Gene expression data of cervical tissue were obtained from the GEO database to analyze the expression of YTHDF2 mRNA and perform pathway enrichment analysis. Patients with cervical lesions diagnosed by thinprep cytologic test in Gynecological Outpatient Department of Maternal and Child Health Hospital in Jiexiu, Shanxi Province, were selected as the research subjects. Data of cervical lesions and cervical exfoliated cells were collected. HPV infection status was detected by flow-through hybridization, and the expression of YTHDF2 mRNA was detected by reverse transcription real-time polymerase chain reaction. The expression of YTHDF2 in cervical lesions and the mediating role of HPV infection in the relationship between YTHDF2 and squamous intraepithelial lesion (SIL) were evaluated. YTHDF2-related genes were screened from multiple datasets in the GEO and ENCORI databases, and their expression, immune infiltration, and survival analysis were performed to assess the association between YTHDF2 and prognosis. Results:Compared with normal cervical tissue, YTHDF2 was highly expressed in cervical lesion tissue ( P<0.05). A total of 3 672 differentially expressed genes were screened from the dataset GSE49339. Gene Ontology analysis showed that YTHDF2 was mainly involved in transcription regulation. Kyoto Encyclopedia of Genes and Genomes analysis showed that YTHDF2 might be related to HPV infection and other signaling pathways. In the mediation analysis, χ2 test results showed that the expression level of YTHDF2 was significantly different among groups ( χ2=22.47, P<0.001). Trend χ2 test further showed that the expression level of YTHDF2 was upregulated with the degree of cervical precancerous lesions (trend χ2=10.26, P=0.001). Multivariate logistic regression analysis indicated that high YTHDF2 expression increased the risk of low-grade squamous intraepithelial lesions ( OR=3.15, 95% CI: 1.93-5.15) and high-grade squamous intraepithelial lesions ( OR=1.85, 95% CI: 1.01-3.39). Mediation effect analysis revealed a partial mediating effect of HPV infection between YTHDF2 and SIL, accounting for 32.02% of the total effect. Twelve YTHDF2 related genes were screened by the intersection of multiple datasets. The immune infiltration analysis results showed that YTHDF2 and related genes KLF4, E2F3 and HOXC6 were associated with immune infiltration (all P<0.05). Multivariate Cox proportional hazard regression model analysis showed that low expression of KLF4 ( HR=0.53, 95% CI: 0.30-0.94) and high expression of RHOB ( HR=1.80, 95% CI: 1.04-3.13) were risk factors for the prognosis of cervical cancer. Conclusion:YTHDF2 is highly expressed in cervical lesions and may have been involved in the regulation of HPV infection-related pathways and its downstream related genes are related to immune infiltration and prognosis of cervical cancer, providing a theoretical basis for the study of mechanisms related to cervical lesions.

The amino-terminal pro-C-type natriuretic peptide(NT-proCNP)is a diagnostic inflam-matory marker clinically used for diagnosing bacterial infections.This study aims to establish a phage display library of single-chain variable fragment(scFv)antibodies against canine NT-proC-NP and to screen for scFvs with high binding affinity to NT-proCNP.Initially,NT-proCNP was prepared using prokaryotic expression system and was used to immunize New Zealand White rab-bits.Upon achieving the desired serum titer,total RNA was extracted from the splenocytes of rab-bits and reverse transcribed into cDNA.Using this cDNA as a template,degenerate primers were employed to amplify the genes of the rabbit antibody light chain variable region(VL)and heavy chain variable region(VH).The VL and VH regions were spliced together to form a complete scFv fragment via overlap extension PCR.The scFv was then ligated into the phagemid pComb3XSS and electroporated into competent E.coli TG1 cells to construct a rabbit-derived anti-NT-proCNP scFv immunological library.This library underwent four rounds of enrichment and screening to isolate specific single-chain antibodies.The selected antibody was subsequently ex-pressed in a soluble form within a prokaryotic system,and its immunological activity was evalua-ted.Using phage display technology,this study successfully identified a single-chain antibody scFv-1-CNP with strong antigen-binding activity and genetic sequence characteristics of scFvs,providing a research direction for further exploration of scFv applications in the detection of NT-proCNP.
