Objective To explore the adverse event signals of children using macrolide drugs (azithromycin, clarithromycin, and erythromycin), and provide reference for rational medicine use in clinical practice. Methods Data from children under 12 years old were extracted from the US FAERS database spanning from the first quarter of 2004 to the second quarter of 2023. The adverse drug reaction (ADR) signal mining for three macrolide antibiotics was conducted using the Reporting Odds Ratio (ROR) and Bayesian Confidence Propagation Neural Network (BCPNN) methods. Special emphasis was placed on analyzing and contrasting the differences in adverse events among the three drugs. Results A total of 1 615 reports for children under 12 years old were retrieved from the FAERS database, including 1 024 reports of azithromycin, 460 reports of clarithromycin, and 131 reports of erythromycin. Among azithromycin and erythromycin, there were more reports from boys than girls, while for clarithromycin, there were more reports from girls than boys. Oral administration was the most common route of administration for all three drugs. Regarding the outcome of adverse events reported, azithromycin and clarithromycin were primarily associated with other serious adverse events, whereas erythromycin was mainly associated with hospitalization and other serious adverse events. The number of adverse events reported decreased with increasing age, with a higher number of reports in the 0-3 age group. Using the ROR and BCPNN methods for signal detection, 86 signals were identified for azithromycin, 91 for clarithromycin, and 34 for erythromycin. These signals involved 22 System Organ Classes (SOCs), with azithromycin mainly concentrated in skin and subcutaneous tissue disorders (n=21), clarithromycin in gastrointestinal disorders (n=15), and erythromycin in gastrointestinal disorders (n=8). Twenty-four signals of moderate to high risk were detected, with 13 for azithromycin, 9 for clarithromycin, and 2 for erythromycin. Conclusion The adverse events induced by the three drugs with different risks in different systems. When clinically treating Mycoplasma pneumoniae pneumonia in children, the risk profiles of drugs in different systems should be considered, and personalized dosing should be implemented.

Objective To investigate the effect of ubiquitin specific peptidase 22 (USP22) on the occurrence and development of esophageal squamous cell carcinoma (ESCC) under hypoxic conditions, and its regulatory relationship with hypoxia-inducible factor-1α (HIF-1α). Methods Western blotting and quantitative polymerase chain reaction were used to detect the differences in USP22 protein and mRNA expression between normal esophageal epithelial cells HEEC and ESCC cell lines KYSE30, KYSE150, EC9706, and TE-1 under normoxic (5% CO2, 20% O2, 75% N2) and hypoxic (5% CO2, 1% O2, 94% N2) conditions. By transfecting USP22 plasmid or siUSP22, ESCC cells were divided into a normoxia control group, a normoxia+USP22 group, a normoxia+siUSP22 group, a hypoxia control group, a hypoxia+USP22 group, and a hypoxia+siUSP22 group. The proliferation and migration abilities of cells in each group were detected. The expression of USP22 and HIF-1α under hypoxic conditions after up-regulating or down-regulating USP22 was detected, and their regulatory relationship was verified. The interaction between USP22 and HIF-1α was verified by co-immunoprecipitation (Co-IP) technique. Results Compared with HEEC cells, the expression of USP22 in ESCC cells was significantly increased (P<0.05). Up-regulation of USP22 expression promoted the proliferation and migration of ESCC cells, while silencing USP22 inhibited the proliferation and migration of ESCC cells (P<0.05). Under hypoxic conditions, the expression of USP22 and HIF-1α increased, and with the up-regulation of USP22 expression, the expression of HIF-1α also significantly increased (P<0.05). Co-IP experiment confirmed the binding between USP22 and HIF-1α. Conclusion Up-regulation of USP22 expression promotes the proliferation and migration of ESCC cells. Hypoxia microenvironment can induce the increase of USP22 expression in ESCC. USP22 may participate in the regulation of the occurrence and development of ESCC by directly binding to HIF-1α.

ObjectiveTo observe the effects of Yifei Tongluo prescription on the NOD-like receptor protein 3 (NLRP3)/Caspase-1/gasdermin D (GSDMD) pathway and epithelial-mesenchymal transition (EMT) in rats with pulmonary fibrosis. MethodsTracheal instillation of bleomycin was conducted to establish a rat model of pulmonary fibrosis. Thirty Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group, a prednisone acetate group (1.17 mg·kg-1), and low- and high-dose Yifei Tongluo prescription groups (10.62 and 21.24 g·kg-1, respectively). Administration started on the 7th day after modeling, once a day for 28 consecutive days. The lung coefficient of each group was calculated. The pathological changes of lung tissues in each group were observed by hematoxylin-eosin (HE) staining and Masson staining. The expression of α-smooth muscle actin (α-SMA) and vimentin in rat lung tissues was detected by immunohistochemistry. The expression of NLRP3 inflammasome, E-cadherin (E-cad), and typeⅠ collagen (ColⅠ) in lung tissues was detected by immunofluorescence. The content of hydroxyproline (HYP), tumor necrosis factor (TNF)-α, interleukin (IL)-18, and IL-1β in rat serum was detected by enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), IL-1β, and transforming growth factor (TGF)-β1 in rat lung tissues were determined by real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of NLRP3, GSDMD, ASC, and Caspase-1 in rat lung tissues were determined by Western blot. ResultsCompared with the blank group, the model group exhibited a significantly increased lung coefficient (P<0.01) and significantly increased range of pulmonary interstitial inflammation and collagen deposition. In addition, the levels of α-SMA, Vimentin, E-cad, and ColⅠ in lung tissues were significantly increased (P<0.01). The levels of fibrosis- and inflammation-related factors HYP, TNF-α, IL-18, and IL-1β in serum were significantly upregulated (P<0.01). The levels of factors related to the activation of NLRP3 inflammasome in lung tissues, including NLRP3, GSDMD, ASC, Caspase-1, IL-1β, and TGF-β1, were significantly upregulated (P<0.01). Compared with the model group, the Yifei Tongluo prescription groups showed improved lung coefficients. Additionally, the extent of lung inflammation and collagen deposition was significantly reduced. The expression of α-SMA, Vimentin, E-cad, and ColⅠ in lung tissue was significantly decreased (P<0.01). The levels of HYP, TNF-α, IL-18, and IL-1β in serum were significantly reduced (P<0.01). The expression levels of NLRP3, GSDMD, ASC, Caspase-1, IL-1β, and TGF-β1 in lung tissue were also significantly decreased (P<0.01). ConclusionYifei Tongluo prescription can regulate the NLRP3/Caspase-1/GSDMD pathway, down-regulate release of pro-inflammatory and pro-fibrotic cytokines, alleviate NLRP3 inflammasome-mediated pyroptosis and EMT, and thereby improve pulmonary fibrosis in rats.

Objective:
To investigate the relationship between physical development indicators and the onset and progression of myopia among children and adolescents, so as to provide theoretical support for coordinated vision and physical health management.
Methods:
A prospective cohort study was conducted. In September 2022, 3 102 students from grade one in primary school to grade three in junior high school (five year primary school and four year junior high school) from six schools in Huantai County, Shandong Province, were selected using multistage cluster random sampling method to participate in an epidemiological survey on myopia, with follow up completed in September 2023. Follow up value minus baseline value( d ) was used to assess changes in physical development and vision indicators. Multivariate Logistic regression analysis was used to examine the relationship between physical development indicators and the incidence of myopia. Generalized linear models were established to analyze the relationship between physical development indicators and changes in d spherical equivalent (SE) and d axial length (AL) .
Results:
Multivariate Logistic regression analysis showed that, after adjusting for factors such as gender, age, and baseline body mass index, the third ( Q 3)and fourth ( Q 4)quartiles of d height showed increased risks of myopia onset within one year compared to the first quartile( Q 1) ( OR =1.85,95% CI =1.18-2.88; OR =1.74,95% CI =1.09-2.78,both P <0.05). Results from the generalized linear model indicated that, after adjusting for confounding factors such as gender, age, and baseline SE, d SE was negatively correlated with d height and d weight in children and adolescents ( β =-0.024, 95% CI =-0.031 to -0.018; β =-0.006, 95% CI =-0.011 to -0.001), d AL was positively correlated with d height and d weight in children and adolescents ( β =0.011, 95% CI =0.008-0.013; β =0.005, 95% CI =0.003-0.007) (all P <0.05).
Conclusions
Physical development indicators in children and adolescents were associated with the onset and progression of myopia. Dynamic monitoring and early intervention of myopia should be strengthened for children and adolescents with rapid height and weight gain to achieve coordinated management of myopia and physical development.

Immobilized enzyme-based enzyme electrode biosensors, characterized by high sensitivity and efficiency, strong specificity, and compact size, demonstrate broad application prospects in life science research, disease diagnosis and monitoring, etc. Immobilization of enzyme is a critical step in determining the performance (stability, sensitivity, and reproducibility) of the biosensors. Random immobilization (physical adsorption, covalent cross-linking, etc.) can easily bring about problems, such as decreased enzyme activity and relatively unstable immobilization. Whereas, directional immobilization utilizing amino acid residue mutation, affinity peptide fusion, or nucleotide-specific binding to restrict the orientation of the enzymes provides new possibilities to solve the problems caused by random immobilization. In this paper, the principles, advantages and disadvantages and the application progress of enzyme electrode biosensors of different directional immobilization strategies for enzyme molecular sensing elements by specific amino acids (lysine, histidine, cysteine, unnatural amino acid) with functional groups introduced based on site-specific mutation, affinity peptides (gold binding peptides, carbon binding peptides, carbohydrate binding domains) fused through genetic engineering, and specific binding between nucleotides and target enzymes (proteins) were reviewed, and the application fields, advantages and limitations of various immobilized enzyme interface characterization techniques were discussed, hoping to provide theoretical and technical guidance for the creation of high-performance enzyme sensing elements and the manufacture of enzyme electrode sensors.
