Objective: To explore the relationship of social anxiety and emotion regulation strategy with short video addiction among college students, so as to provide reference for alleviating social anxiety, improving the level of emotion regulation and preventing short video addiction. Methods: From May to June 2024, 2 172 college students from a university in Guangzhou were selected by multistage random cluster sampling method. The Interaction Anxiousness Scale, Emotion Regulation Questionnaire and Short Video Addiction Scale were used as the measurement tools. The potential profile was used to analyze the potential categories of social anxiety and emotion regulation strategy. The Chi square test was used to analyze the characteristics of the distribution of potential profile categories of college students with different demographic characteristics. Multiple linear regression analysis was used to analyze the relationship between social anxiety, emotion regulation strategy and short video addiction. Results: The potential categories of social anxiety and emotion regulation strategy in college students were divided into adaptive regulation type (784 cases, 36.10 %), low anxiety-expression type (623 cases, 28.68%), inhibition-anxiety type (478 cases, 22.01%), high anxiety-disorder type (287 cases, 13.21%). There were statistically significant differences in the distribution of various potential categories of social anxiety and emotion regulation strategy among cadres of different gender, family residence, class cadres or not ( χ 2=42.55, 17.86 , 39.05, all P <0.01). Multiple linear regression analysis showed that after controlling the confounding factors such as demographic variables, the potential categories of social anxiety and emotion regulation strategy of college students (low anxiety-expression type, inhibition-anxiety type, high anxiety-disorder type) were the important related factors of short video addiction ( β =0.15,0.25,0.35, all P <0.05). Conclusions Social anxiety and emotion regulation strategy of college students exhibit distinct categorical characteristics, and its varying latent categories are associated with short video addiction. Schools should implement targeted intervention measures for different categories of college students to promote their comprehensive mental health development.

Objective:To investigate the potential mechanism of cellular senescence-related mitochondrial autophagy genes in diabetic retinopathy (DR).Methods:The DR gene datasets GSE53257 and GSE60436 from the GEO database and screened the differentially expressed genes (DEG) were downloaded. Cellular senescence-related genes and mitochondrial autophagy-related genes from the GeneCards database, and the intersection of the two to obtain the DR-related differentially expressed genes (CSRMRDEG) were collected. The obtained CSRMRDEG was subjected to Gene Ontology (GO) functional enrichment analysis, Kyoto Encyclopedia of Genes and Genomes (KEGG) signaling pathway enrichment analysis, protein-protein interaction network (PPI) analysis, and hub gene identification using Maximal Clique Centrality (MCC), Degree, Maximum Neighborhood Component (MNC)、Edge Percolated Component (EPC) and Closeness algorithms. Gene Set Enrichment Analysis (GSEA) was conducted to obtain the enriched pathways of DEG, and ssGSEA immune infiltration analysis was performed to screen the correlation between immune cells and DR. The diagnostic efficacy of hub genes for DR was evaluated by drawing the receiver operating characteristic (ROC) curve and calculating the area under the curve (AUC). Meanwhile, the Wilcoxon rank sum test was used to compare the differences in the infiltration level of immune cells between the DR Group and the control group.Results:23 DR-related CSRMRDEG were obtained. GO analysis showed that they were mainly enriched in the pathways of dicarboxylic acid, biosynthetic process of folate-containing compounds, tetrahydrofolate conversion, mitochondrial matrix, mitochondrial endomembrane, structural components of ribosomes, and glutamate transmembrane transporter protein activity. The results of KEGG pathway enrichment analysis showed that CSRMRDEG was highly enriched in pathways such as the folate carbon pool, biosynthesis of cofactors, and pyruvate metabolism. The PPI analysis results show that there are 16 related CSRMRDEG. Five algorithms (MCC, Degree, MNC, EPC, Closeness) obtained the nine Hub genes. The results of ROC curve analysis showed that the AUC of the expression levels of 9 hub genes for diagnosing DR ranged from 0.7-0.9. The ssGSEA results showed that there were statistically significant differences in Wilcoxon of central memory CD4 + T cells, macrophages, natural killer cells, and helper T cell 1 between the DR group and the control group ( Z=-2.85, -2.23, -2.10, -2.52; P<0.05). Conclusion:Mitochondrial autophagy genes related to cellular senescence are potential diagnostic targets for DR.

Objective: To explore the causal relationship between academic procrastination, negative emotions, self control, and smartphone addiction among college students, so as to provide theoretical reference for promoting their mental health and academic achievement. Methods: A multi stage cluster random sampling method was used to select 452 first year students from a university in Guangzhou as the research subjects. Procrastination Assessment Scale- Student (PASS), The Depression Anxiety Stress Scale (DASS-21), Self Control Scale, and Short Version of the Smartphone Addiction Scale (SAS-SV) were used as measurement tools. Three questionnaire surveys were completed in October 2024 (T1), February 2025 (T2), and May 2025 (T3). Coss lagged models were utilized to analyze the causal relationship between academic procrastination, negative emotions, self control, and smartphone addiction. Results: The SAS-SV scale for college students showed an average score of (40.52±1.96), with 43.1% of freshmen exhibiting smartphone addiction.Positive correlations were observed between academic procrastination, negative emotions, and smartphone addiction across different time points, while self control exhibited negative correlations with these three variables ( r = 0.30 -0.62, -0.72 to -0.34, all P <0.05). Cross lagged model results indicated that academic procrastination and negative emotions at T1 and T2 positively predicted smartphone addiction at T2 and T3 (T1→T2, β =0.22, 0.35; T2→T3, β =0.21, 0.24; all P < 0.05 ). Self control negatively predicted smartphone addiction (T1→T2, β =-0.32; T2→T3, β =-0.26; both P <0.05). In reverse causality regression models, smartphone addiction at T1 and T2 positively predicted academic procrastination and negative emotions at T2 and T3 (T1→T2, β =0.09, 0.24; T2→T3, β =0.10, 0.35; all P <0.05), but no statistically significant predictions were found for self control (T1→T2, β =-0.04; T2→T3, β =-0.03; both P >0.05). Conclusion Academic procrastination and negative emotions exhibit bidirectional causality with smartphone addiction among college students, while self control unidirectionally predicts smartphone addiction.

Objective: Randomized controlled trials (RCTs) of Chinese patent medicines and classic traditional Chinese medicine prescriptions were systematically reviewed from both Chinese and English journals published in 2023. A preliminary summary and evaluation were conducted on the generation and translation of clinical evidence for these treatments. This analysis aims to inform future research on clinical efficacy evaluation and guide the rational application of evidence. Methods: RCTs of Chinese patent medicines and classic traditional Chinese prescriptions published in 2023 were comprehensively retrieved from the Artificial Intelligence Clinical Evidence Database for Chinese Patent Medicine (AICED-CPM), with supplementary searches conducted in China National Knowledge Infrastructure (CNKI), Wanfang Data, Chinese Science and Technology Journal Database (VIP), Chinese Biomedical Literature Database (SinoMed), Cochrane Library, PubMed, Embase, and Web of Science. The study characteristics and methodological quality of these RCTs were systematically analyzed and evaluated. Results: A total of 1 443 RCTs of Chinese patent medicines were included, comprising 1 399 Chinese articles and 44 English articles. Additionally, 334 RCTs of classic traditional Chinese medicine prescriptions were found, with 331 published in Chinese and 3 in English. 196 567 participants were included, covering 585 types of Chinese patent medicines (487 oral, 61 injectable, and 37 topical) and 179 classic traditional Chinese medicine prescriptions. The involved studies encompassed 22 types of diseases, with research primarily focusing on diseases of the circulatory system, the respiratory system, and the genitourinary system. The sample sizes ranged from 18 to 3 777 participants, and most studies were conducted at a single center. Methodologically, the implementation of allocation concealment and blinding remained insufficiently emphasized. Conclusion Overall, compared with 2022, both the number of RCT publications and their methodological quality have improved in 2023, with heightened attention to research on diseases of the genitourinary system. However, quality control and standardized management in the design and implementation processes still require enhancement to produce more high-quality clinical evidence and accelerate the translation and application of this evidence.
