Objective: To investigate the association between different digital media usage types and depressive symptoms among junior and senior high school students, so as to provide a scientific reference for making precise mental health prevention and intervention strategies for adolescents. Methods: In October 2024, a convenience cluster sample of 3 225 students was collected from 2 junior high schools and 2 senior high schools in Shenyang City. Participants were investigated for its daily usage duration of various digital media types and depressive symptoms. Cochran-Armitage trend test was used to examine trend in depressive symptom detection rates across digital media usage types. Multivariate Logistic regression model was employed to assess associations, with stratified analyses by gender and educational stage. Results: The daily usage durations for educational/learning, social/chatting, gaming, and video/music/novel digital media were 30.0(12.1, 60.0), 22.9(9.3, 50.0), 17.1(0.0, 50.0), and 22.9(8.6, 55.7) minutes for junior and senior high school students, respectively. The detection rate of depressive symptoms was 46.1%. Among them, the detection rate of depressive symptoms of girls (49.8%) was higher than that of boys (42.3%), and that of senior high school students (53.2%) was higher than that of junior high school students (39.7%), and the differences were statistically significant ( χ 2= 18.35, 59.02, both P <0.01). Cochran-Armitage trend test revealed significant upward trends in depressive symptom detection rates with increasing usage of non educational digital media (social/chatting: Z =4.77; gaming: Z =3.24; video/music/novel: Z =7.30, all P <0.01). Logistic regression analysis showed that, compared to usage <1 h/d, using social/chatting digital media for 1-<2 h/d ( OR =1.66), 2-<3 h/d ( OR =1.80), and ≥3 h/d ( OR =2.68), gaming for 1-<2 h/d ( OR =1.48), 2-<3 h/d ( OR =1.90), and ≥3 h/d ( OR =2.93), and video/music/novel for 1-<2 h/d ( OR =1.76), 2-<3 h/d ( OR =2.00), and ≥3 h/d ( OR = 3.48) were all significantly associated with increased risks of depressive symptoms (all P <0.01). Conclusions Excessive use of non-educational digital media is a risk factor for depressive symptoms in adolescents. Regulating usage duration is beneficial for promoting adolescent mental health.

Objective To investigate the 30-day mortality risk factors in elderly patients with heart failure with reduced ejection fraction (HFrEF) after isolated coronary artery bypass grafting (CABG) and to construct a nomogram for predicting mortality risk. Methods A retrospective analysis of elderly (≥70 years) HFrEF patients undergoing isolated CABG at Tianjin Chest Hospital from 2010 to 2024 was performed. Simple random sampling in R software was used to divide the dataset into training and validation sets in a 7 : 3 ratio. The training set was further divided into survivors and non-survivors. Univariate logistic regression was performed to identify differences between groups, followed by multivariate logistic regression to select independent risk factors for death and to establish a death-risk nomogram, which underwent internal validation. The predictive value of the nomogram was assessed by plotting receiver operating characteristic (ROC) curves, calibration curves, and decision-curve analyses for both the training and validation sets. Results A total of 656 patients were included. The training set consisted of 458 patients (survivors 418, deaths 40); the validation set consisted of 198 patients (survivors 180, deaths 18). In the training set, univariate analysis showed significant differences between survivors and deaths for creatinine (Cr) level, brain natriuretic peptide (BNP), maximum Cr, intra-aortic balloon pump (IABP) use, assisted ventilation, reintubation, hyperlactatemia, low cardiac output syndrome, and renal failure (P<0.05). After multivariable logistic regression, five independent risk factors were identified: IABP use (OR=3.391, 95%CI 1.065-11.044, P=0.038), reintubation (OR=15.991, 95%CI 4.269-67.394, P<0.001), hyperlactatemia (OR=8.171, 95%CI 2.057-46.089, P=0.007), Cr (OR=4.330, 95%CI 0.997-6.022, P=0.024), and BNP (OR=1.603, 95%CI 1.000-2.000, P=0.010). Accordingly, a nomogram predicting mortality risk was constructed. The ROC and calibration analyses indicated good predictive value: area under the curve (AUC) in the training set was 0.898 (95%CI 0.831-0.966) and in the validation set was 0.912 (95%CI 0.805-1.000). Calibration and decision-curve analyses showed good agreement and clinical utility. Conclusion The nomogram incorporating IABP use, reintubation, hyperlactatemia, creatinine, and BNP provides good predictive value for 30-day mortality after CABG in elderly patients with HFrEF and demonstrates potential clinical utility.

Artificial life is the goal pursued by cognitive philosophy， cognitive science， and artificial intelligence， yet its realization has consistently encountered challenge. The generative mechanisms of artificial life include self-organization， emergence， and agency， all of which are difficult to precisely grasp in the cognitive paradigm. Evolutionary biology demonstrates that natural life possesses extraordinary adaptability. For artificial artifacts， the way to endow them with life-like characteristics involves first transforming them into self-organizing systems with emergence， and then evolving them into embodied agents possessing agency and moral cognitive capacity. This process reveals the functional and informational properties of artificial life， manifesting its adaptive representational character.

ObjectiveTo establish a model of dry eye with lung Yin deficiency syndrome in mice. MethodsA total of 40 SPF C57BL/6J mice were assigned via the random number table method into 5 groups （n=8）： Normal control， model control， and high-， medium-， and low-dose （11.7， 5.85， and 2.925 g·kg^-1， respectively） Yangyin Qingfeitang. Mice in the normal control group were fed normally without any intervention. Mice in Yangyin Qingfeitang group and model control group were treated with 0.2% benzalkonium chloride eye drops （5 μL） twice a day and fed in a controlled drying system in a dry environment for 28 days. At the same time， the mice were administrated with thyroxine tablet solution by gavage and placed in a glass fumigation tank （SO₂ concentration： 0.5 g·m^-3） for 14 days. After 4 weeks， mice in Yangyin Qingfeitang groups were treated with Yangyin Qingfeitang by gavage and those in the normal control group and model control group were administrated with deionized water at 0.01 mL·g^-1. The body mass， anal temperature， four examination information （claw and nail appearance）， basic tear secretion test， tear film rupture time， corneal fluorescein staining， and lacrimal gland HE staining were compared among groups. Compound Yangyin Qingfeitang granules were used to measure the syndrome to verify the success of modeling. ResultsAfter 28 days of continuous modeling， compared with the normal control group， the model group exhibited listless and emaciated status， coughing， drowsiness， dry and dull hair， dry and hard stool， reduced food intake and water intake， red lip circumference， red tongue with reduced fluid， dry nose and teeth， red claws and nails， body mass gain， decreased anal mild tear secretion （P<0.05）， and shortened tear film rupture time （P<0.05）. After 28 days of modeling， the mice showed large corneal fluorescein staining range， severe corneal injury， and increased content of interleukin （IL）-18， IL-β， and tumor necrosis factor （TNF）-α in lacrimal gland， compared with those in the normal control group （P<0.05）. After the treatment with Yangyin Qingfeitang， the mice had good drinking and eating conditions， with lighter redness of the tongue， moist nose， moist and shiny teeth， and the claw and nail color close to that in the normal group. Compared with the model control group， Yangyin Qingfeitang groups showed increases in body mass and anal temperature （P<0.05）， tear secretion （P<0.05）， and tear film rupture time （P<0.05）， narrowed range of corneal fluorescein staining， and declined levels of IL-18， IL-β， and TNF-α in lacrimal glands （P<0.01）. The high-dose group had the best effect， with the indicators close to the levels in the normal control group. ConclusionThe animal model of dry eye with lung Yin deficiency syndrome can be established by culture in a controlled drying system， treatment with benzalkonium chloride eye drops for 28 days， and administration of thyroxine tablet solution combined with SO₂ fumigation for 14 days.

BACKGROUND Sepsis is a prevalent and severe condition, with microcirculation disruptions playing a crucial role in its progression. Endothelial cell (EC) injury is the primary factor behind microcirculatory issues. This review is to outline the pathomechanism, organ heterogeneity, biomarkers, and therapeutic implications of endothelial dysfunction in sepsis, offering references and insights for the clinical management of sepsis. METHODS: A systematic search of Web of Science and PubMed from inception to June 10, 2025, limited to English publications, was conducted. Two reviewers independently identified studies on EC injury in patients with septic microcirculatory dysfunction. Duplicate articles based on multiple search criteria were excluded. RESULTS: Fifty-nine articles, including cell, animal, and clinical studies, were included. These studies reported the effects of EC injury on the microcirculation in sepsis, including changes in vascular permeability, coagulation dysfunction, vasomotor regulation, and inflammatory responses. These pathways interact and ultimately lead to septic microcirculation disorders. CONCLUSION: Sepsis-induced endothelial dysfunction involves various interconnected mechanisms, which collectively compromise ECs and impede microcirculatory perfusion. Future research should enhance current understanding of endothelial injury mechanisms, develop synergistic multi-target strategies to disrupt this cycle, and facilitate the clinical application of endothelial markers for early intervention and dynamic assessment.

Abstract To further differentiate the differentiated effects of emotional responses to social media among adolescents, the study systematically reviews the main current methods for measuring social media emotional responses. It elaborates on the impacts of adolescents emotional responses to social media on their physical health, mental health, and social adaptation, as well as the multiple pathways and potential mechanisms through which adverse health effects are induced. It also highlights the current lack of empirical support for biological mechanisms in existing research, and provides a reference for future in depth exploration of biological mechanisms and the development of effective intervention strategies.

High-throughput sequencing-based high-throughput screening （HTS²） technology， as a new advancement in the field of high-throughput biotechnology， is the world's first technology to integrate high-throughput sequencing into large-scale drug screening and target discovery. The artificially designed DNA probes were bound to the undetermined mRNAs of thousands of genes in cell lysates， and then the probes were ligated with ligases. The large-scale simultaneous detection of gene expression changes in thousands of drug-treated cell samples was performed using barcoding， automated operating platforms， and high-throughput sequencers. This technology enables high-throughput identification of drugs that significantly perturb the gene expression profiles characteristic of diseases. It can also take gene expression signature as the readout and exert great high-throughput advantages in the screening of multi-drug， multi-component， and multi-target drugs， as well as the research on complex mechanisms. Therefore， it is particularly suitable for elucidating the multi-target mechanisms of traditional Chinese medicine and identifying its multi-effective components. Its main technical advantages include high throughput， automation， and low cost. In recent years， HTS² technology has yielded important achievements in the elucidation of the mechanism of action of traditional Chinese medicine formulas， the scientific connotation analysis of the regional characteristics of traditional Chinese medicine， the targeted isolation of active compounds of traditional Chinese medicine， and the discovery of novel pharmacological functions of monomeric compounds of traditional Chinese medicine. In the era of artificial intelligence， HTS² technology will serve as a powerful tool for generating high-quality， original big data of traditional Chinese medicine， providing core data support and promoting AI-driven traditional Chinese medicine research. Ultimately， HTS² technology offers new strategies and critical data support for deeply analyzing the scientific connotation of traditional Chinese medicine and discovering novel traditional Chinese medicine-based drugs， thereby accelerating the modernization and internationalization of traditional Chinese medicine in China.

Objective: To explore the regulatory role of paternal involvement in parenting in the association between parental adverse childhood experiences (ACEs) and autism like behavioral problems in children aged 3-6, so as to provide a basis for intervention strategies targeting the intergenerational health effects of ACEs. Methods: A longitudinal study design was used to select 1 780 children aged 3-6 from 12 kindergartens in Wuhu City, Anhui Province in June 2021 as the subjects of the baseline survey by convenient sampling, and the follow up surveys were conducted once every six months, for a total of two follow ups. Pearson correlation analysis was used to examine the association of parental ACEs and paternal involvement in parenting with autism like behavioral problems in children. A binary Logistic regression model was used to explore the association between parental ACEs and autism like behavioral problems in children. Based on stratification, the potential role of paternal involvement in the association between parental ACEs and autism like behavioral problems in children aged 3-6 was explored. Results: Autism like behavioral problem score in children aged 3-6 was positively correlated with the total score ACEs of parents as well as scores of emotional abuse, physical abuse, sexual abuse, emotional neglect, physical neglect, community violence, peer bullying, and family dysfunction( r =0.18,0.16,0.18,0.14,0.06,0.05,0.12,0.18,0.09,all P <0.05). Autism like behavioral problem score in children was negatively correlated with score of paternal involvement in parenting( r =-0.16, P <0.01). After adjusting for covariates such as gender, age, and birth weight of children, binary Logistic regression analysis showed that children whose parents had experiences of childhood emotional abuse, physical abuse, sexual abuse, community violence, peer bullying, or family dysfunction had higher risks of developing autism like behavioral problems than those in the non exposed group ( OR =3.29, 3.28, 6.71, 2.34, 4.08, 2.02, all P <0.01). In the group with low paternal involvement in parenting, all dimensions of parental ACEs(emotional abuse, physical abuse, sexual abuse, community violence, peer bullying, and family dysfunction) were significantly associated with an increased risk of autism like behavioral problems in children ( OR =1.84-8.34, all P <0.05). In contrast, in the group with high paternal involvement in parenting, no statistically significant associations were found between any dimension of parental ACEs and children s autism like behavioral problems ( OR =0.57-1.82, all P >0.05). Conclusion A high level of paternal involvement in parenting can reduce the adverse effects of parental ACEs on the occurrence of autism like behaviors in preschool children.

Objective To analyze the application of NCompass nitinol stone retrieval basket in ureteroscopic holmium laser lithotripsy, and to evaluate its roles in reducing stone retropulsion and improving stone-free rate(SFR)and stone acquisition rate.Methods A retrospective analysis was conducted on the data of patients with upper ureteral stones＞1 cm who underwent ureteroscopic holmium laser lithotripsy at China-Japan Friendship Hospital during Jan.2018 and Dec.2023, including 96 cases were in the NCompass group, and 68 cases in the non-basket group.The operation time, stone retropulsion rate, usage rate of flexible ureteroscopy, SFR and stone acquisition rate were compared between the two groups.Results There were no significant differences in the operation time [(29.2±8.4)min vs.(30.9±7.2)min, P=0.170] and stone retropulsion rate(15.6% vs. 27.9%, P=0.055)between the NCompass group and non-basket group.The NCompass group had significantly lower usage rate of flexible ureteroscopy than the non-basket group(24.0% vs. 47.1%, P=0.002), higher SFR 2 days(80.2% vs. 45.6%, P＜0.001)and 1 month(93.8% vs. 83.8%, P=0.040)after operation, as well as the stone acquisition rates 2 days(100% vs. 44.1%, P＜0.001)and 1 month(100% vs. 58.8%, P＜0.001)after operation. Conclusion The NCompass nitinol stone retrieval basket plays dual roles in ureteroscopic holmium laser lithotripsy, which can effectively intercept stones and extract stone fragments, thus significantly improving the SFR and stone acquisition rate, and reducing stone retropulsion and the use of flexible ureteroscopy.
