Objective: To explore the correlation between adverse childhood experiences (ACEs) and digital self harm behavior among college students, so as to provide scientific evidence for preventing and intervening digital self harm behavior. Methods: A total of 5 917 college students from five provinces (Anhui, Guangdong, Hebei, Jilin, and Sichuan) were selected by using a method combining stratified cluster random sampling with convenient sampling to complete an electronic questionnaire survey, from May to June 2024. The survey was conducted to assesse digital self harm behavior and ten dimensions of ACEs, including peer bullying, emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, adverse family events, adverse school or social events, adverse life experiences, and personal adverse problems. A multivariable Logistic regression model was used to analyze the association between ACEs and digital selfharm among college students. Results: The reporting rate of digital self harm behavior among college students was 11.5%. There were statistically significant differences in the reporting rates of digital self harm behaviors among college students with different household registration location and the numbers of close friends ( χ 2=3.91, 8.09 , both P <0.05). Univariate analyses showed that the prevalence of digital self harm behavior was significantly higher among students who reported any type of ACEs compared with those without such experiences ( χ 2=7.99-27.63, all P <0.01). After controlling for demographic variables, each type of ACE was separately included in multivariable Logistic regression models as an independent variable, and all types of ACEs were significantly associated with digital self harm behavior among college students ( OR =1.27-1.91, all P <0.01). Notably, the OR values for sexual abuse and personal adverse problems were relatively high, being 1.91 and 1.83 respectively. Moreover, the risk of reporting digital self harm increased with the number of types of ACEs ( OR= 1.17 , P <0.01). Conclusions ACEs are related factors for digital self harm behavior among college students. Early psychological intervention should be strengthened, particularly for college students who have experienced sexual abuse and personal adverse problems during childhood.

Objective To investigate the causal relationship between gut microbiota and obstruc-tive sleep apnea syndrome(OSA)using a two-sample bidirectional Mendelian randomization(MR)approach.Methods Eligible single nucleotide polymorphisms(SNPs)were selected from genome-wide association study(GWAS)databases as instrumental variables.A bidirectional MR analysis was conducted to evaluate the causal effects between gut microbiota and OSA.Various statistical methods,including the inverse variance weighted(IVW)method,MR-Egger regression,the weighted model method,and the weighted median method,were employed for association assessment.The MR pleiot-ropy residual sum and outlier(MR-PRESSO)test,along with Cochran's Q test and the leave-one-out cross-validation method,were used to assess heterogeneity and pleiotropy.Results According to the IVW method analysis,an increased abundance of the genus Faecalibacterium(sp002397985)(OR=0.847,95％CI,0.719 to 0.997,P=0.046)was associated with a reduced risk of OSA.Conversely,increased abundances of the genera Bacteroides(OR=1.075,95％CI,1.016 to 1.138,P=0.012),Haemophilus(sp001679485)(OR=1.106,95％CI,1.016 to 1.203,P=0.021),Streptococcus(OR=1.168,95％CI,1.036 to 1.316,P=0.011),and Blautia(sp002159835)(OR=1.169,95％CI,1.035 to 1.319,P=0.012)were associated with an elevated risk of OSA.The reverse MR analysis revealed no significant association between the risk of OSA and the abundance of gut microbiota.The results of Cochran's Q test,MR-Egger test,and MR-PRESSO test indicated no het-erogeneity or horizontal pleiotropy(P＞0.05).Conclusion Causal relationships exist between the five genera(Faecalibacterium,Bacteroides,Haemophilus,Streptococcus,and Blautia)and the risk of OSA.

Houpo Sanwutang， included in the Catalogue of Ancient Classical Prescriptions （Second Batch）， was first recorded in the Synopsis of Golden Chamber written by ZHANG Zhongjing from the Eastern Han dynasty and was modified by successive generations of medical experts. A total of 37 pieces of effective data involving 37 ancient Chinese medical books were retrieved from different databases. Through literature mining， statistical analysis， and data processing， combined with modern articles， this study employed bibliometrics to investigate the historical origin， composition， decoction methods， clinical application， and other key information. The results showed that the medicinal origin of Houpo Sanwutang was clearly documented in classic books. Based on the conversion of the measurements from the Han Dynasty， it is recommended that 110.4 g Magnolia Officinalis Cortex， 55.2 g Rhei Radix et Rhizoma， and 72 g Aurantii Fructus Immaturus should be taken. Magnolia Officinalis Cortex and Aurantii Fructus Immaturus should be decocted with 2 400 mL water first， and 1 000 mL should be taken from the decocted liquid. Following this， Rhei Radix et Rhizoma should be added for further decoction， and then 600 mL should be taken from the decocted liquid. A single dose of administration is 200 mL， and the medication can be stopped when patients restore smooth bowel movement. Houpo Sanwutang has the effect of moving Qi， relieving stuffiness and fullness， removing food stagnation， and regulating bowels. It can be used in treating abdominal distending pain， guarding， constipation， and other diseases with the pathogenesis of stagnated heat and stagnated Qi in the stomach. The above results provide reference for the future development and research of Houpo Sanwutang.

Objective To explore the mechanisms of Qingre Lidan Jiedu Recipe(QLJR)for improving cognitive dysfunction in rats with high copper load.Methods Seventy-five male SD rats were randomized into normal control group,model group,QLJR group,penicillamine(PCA)group,and QLJR+PCA group.Except for those in the control group,all the rats were fed a high-copper diet for 12 weeks.The effects of the treatments on cognitive function of the rats were assessed using the Barnes maze and passive avoidance tests.Hippocampal expressions of NIX,FUNDC1 and LC3 of the rats were detected using Western blotting and immunofluorescence staining,and changes in mitochondrial morphology were observed with transmission electron microscopy.Results Behavioral tests showed prolonged target hole latency,shortened latency to enter the dark chamber,and increased error counts of the rats in the model group,which were significantly improved in QLJR+PCA group;the error counts were significantly lower in QLJR+PCA group than in either QLJR or PCA group.Among all the groups,the hippocampal expressions of NIX and FUNDC1 were the lowest and LC3 I/II expression the highest in the model group;NIX and FUNDC1 expressions were significantly higher and LC3 I expression was lower in QLJR+PCA group than in QLJR group and PCA group.Immunofluorescence staining revealed weakened NIX and FUNDC1 expressions and enhanced LC3 expression in the hippocampus of the rats in the model group as compared with those in the normal control and QLJR+PCA groups,but their expressions did not differ significantly between QLJR and PCA groups.The rats in the model group showed obvious structural disarray of the mitochondria,which were improved in all the treatment groups.Conclusion QLJR improves cognitive dysfunction in rats with high copper load possibly by regulating mitophagy.

Intestinal fibrosis is a significant clinical challenge in inflammatory bowel diseases, but no effective anti-fibrotic therapy is currently available. Glucagon receptor (GCGR) and glucagon-like peptide 1 receptor (GLP1R) are both peptide hormone receptors involved in energy metabolism of epithelial cells. However, their role in intestinal fibrosis and the underlying mechanisms remain largely unexplored. Herein GCGR and GLP1R were found to be reduced in the stenotic ileum of patients with Crohn's disease as well as in the fibrotic colon of mice with chronic colitis. The downregulation of GCGR and GLP1R led to the accumulation of the metabolic byproduct lactate, resulting in histone H3K9 lactylation and exacerbated intestinal fibrosis through epithelial-to-mesenchymal transition (EMT). Dual activating GCGR and GLP1R by peptide 1907B reduced the H3K9 lactylation in epithelial cells and ameliorated intestinal fibrosis in vivo. We uncovered the role of GCGR/GLP1R in regulating EMT involved in intestinal fibrosis via histone lactylation. Simultaneously activating GCGR/GLP1R with the novel dual agonist peptide 1907B holds promise as a treatment strategy for alleviating intestinal fibrosis.
