ObjectiveTo explore the interaction and competitive binding of Homo sapiens long intergenic non-protein-coding RNA 1134 (LINC01134) to CCCTC-binding factor CTCF, affecting the transcription of cyclin-dependent kinase inhibitor (p21) and influencing the proliferation of A549 cells, in order to investigate the possible mechanism of Astragali Radix and Hedyotis diffusa (A-H) in inhibiting A549 proliferation by regulating this axis. MethodsRNA-binding protein immunoprecipitation (RIP) assays were conducted to examine the interaction between LINC01134 and CTCF, and chromatin immunoprecipitation (ChIP) assays were used to study the effect of LINC01134 overexpression on the interaction between CTCF and p21. Stable A549 cell lines (oe-NC and oe-LINC01134) were established using lentiviral transfection, and each group was treated with 10% A-H drug-containing serum. Real-time PCR and Western blot analyses were performed to detect the effects of A-H on the expression of LINC01134, CTCF, and p21 in A549 cells. Cell counting kit-8 (CCK-8) and colony formation assays were used to assess the effects of A-H on A549 cell proliferation via LINC01134. Flow cytometry was employed to evaluate the effects of A-H on the A549 cell cycle through LINC01134, and Western blot was used to detect changes in cell cycle proteins. ResultsCompared with the IgG group, the oe-CTCF group showed a significantly increased abundance of LINC01134 aggregates (P0.01). Compared with the oe-Vector group, p21 abundance in CTCF complexes was significantly reduced in the oe-LINC01134 group (P0.01). Compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed the expression of LINC01134 and p21 (P0.05), but had no significant regulatory effect on CTCF. Compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed cell viability at 72 h (P0.05), inhibited malignant proliferation (P0.05), and reversed the proportions of cells in the G0/G1 and S phases (P0.01). Furthermore, compared with the 10% blank + oe-LINC01134 group, the 10% A-H + oe-LINC01134 group reversed the expression of Cyclin D1, CDK4, Cyclin E, CDK2, phosphorylated retinoblastoma protein (p-Rb), and E2F transcription factor 3 (E2F3) (P0.01). ConclusionA-H regulates the LINC01134-CTCF-p21 axis to block the G1/S phase transition of A549 cell cycle, accelerate cellular senescence, and inhibit malignant proliferation.

The Proctor's reporting guideline for implementation strategies represents a landmark framework in the field of implementation science, aiming to address the issue of inconsistent reporting in implementation research by standardizing the naming, definition, and operationalization of implementation strategies, thereby enhancing the credibility and utility of research findings. This paper provides an in-depth interpretation of the core connotations of this reporting guideline and illustrates its application in developing interview outlines and specifying implementation strategies, using a brief smoking cessation intervention project as a case study. Through this reporting guideline, abstract recommendations for implementation are systematically transformed into clear, multidimensional operational guides, significantly improving the transparency of strategy connotations and the replicability of actual execution. Meanwhile, the case study highlights the flexibility of the guideline, which allows researchers to adapt the content and format of strategies based on local resources and cultural contexts, thus enhancing practical adaptability while maintaining scientific rigor. However, the application of Proctor's reporting guideline still faces challenges, primarily manifested in the potential confusion surrounding the constructs of temporality and dose in practice, as well as the challenges that the inherent flexibility of the guideline may pose to the assessment of fidelity and effectiveness. Despite these limitations, the reporting guideline remains a vital tool for implementation research; future efforts should focus on optimizing its application—through refining operational guidelines, standardizing flexible adaptations, and involving stakeholders—to better guide implementation studies and continuously promote high-quality development in the field.

ObjectiveTo investigate somatization symptoms in adolescents during frequent earthquakes in Hefei, and to explore their correlation with earthquake experiences. MethodsA cross-sectional survey was used to select 324 adolescents in Hefei as the survey objects. The self-rating scale of somatization symptoms (SSS) and the fatigue intensity scale (FIS) were used to evaluate the somatization symptoms and fatigue degree of middle school students, and multivariate Logistic regression analysis was used to explore the related factors of somatization symptoms and fatigue among middle school students. ResultsA total of 324 adolescents were included, and the overall detection rate of somatization symptoms was 6.5%, and the detection rate of moderate or above fatigue was 20.1%. The results of regression analysis showed that adolescents who were concerned about the earthquake for a longer time (≥1 h) had a higher risk of somatization symptoms (OR=5.430, 95%CI: 1.547-19.058), and adolescents who received pre-earthquake training had a lower degree of fatigue (OR=0.535, 95%CI: 0.292-0.981) (P<0.05). ConclusionDuring the frequent earthquakes, adolescents have more somatization symptoms and fatigue. Therefore, it is crucial to enhance health education, reduce the emphasis on event-related reports, and implement earthquake prevention and disaster reduction training to improve the physical and mental health of adolescents.

Objective:
To analyze the developmental trajectories of clustered health risk behaviors and their association with self-esteem and lonelinesss among junior high school students, so as to provide a reference for formulating comprehensive prevention and control measures of health risk behaviors among adolescents.
Methods:
In October 2023, 1 165 first year junior high school students from two schools of Jishou City in Hunan Province were selected by convenient sampling method for three follow up surveys (T1:October 2023; T2:April 2024; T3:October 2024). The Adolescent Health Risk Behavior Questionnaire, Rosenberg Self esteem Scale and Loneliness Scale were used to assess health risk behaviors, self esteem and loneliness, respectively. Latent growth curve modeling and latent growth mixture modeling were applied to analyze the developmental trajectories of clustered health risk behaviors among junior high school students. Logistic regression was used to analyze the association of the developmental trajectories of clustered health risk behaviors with self esteem and loneliness among junior high school students.
Results:
The overall developmental trajectories among junior high school students showed a declining trend (intercept=0.15, slope=-1.65, both P <0.05), with three heterogeneous categories:low risk improvement group ( n =862, 74.0%), moderate risk stable group ( n =260, 22.3%), and high risk deterioration group ( n =43, 3.7%). After adjusting the status of the left behind individuals,using the low risk improvement group as the reference category in multinomial Logistic regression analysis, results indicated that higher loneliness scores among junior high school students increased the risks of belonging to the moderate risk stable group ( OR=1.02, 95%CI =1.00- 1.04 ) and the high risk deterioration group ( OR=1.04, 95%CI =1.00-1.08), while higher self esteem scores reduced the risks of belonging to the moderate risk stable group ( OR=0.93, 95%CI =0.91-0.96) and the high risk deterioration group ( OR=0.88, 95%CI =0.83-0.94) (all P <0.05).
Conclusions
The overall trend of clustered health risk behaviors among junior high school students gradually improves, and the self esteem and loneliness are significant correlative factors. Targeted intervention measures should be developed for the junior high school students, with a focus on enhancing their self esteem and alleviating loneliness.

Chinese Journal of School Health 2026;47(3):398-402
Objective:
To explore the impact of adverse childhood experiences (ACEs) on health risk behaviors (HRBs) among college students and the mediating role of psychological symptoms, so as to provide a basis for developing intervention strategies.
Methods:
From March to April 2023, a convenience cluster sample of 1 801 students from 12 universities in Nanning, Liuzhou, Guilin, Wuzhou of Guangxi completed an online survey. A self designed questionnaire, Adverse Childhood Experiences-International Questionnaire (ACE-IQ) and Symptom Checklist-90 (SCL-90) were used for evaluation tools. Binary Logistic regression, structural equation modeling (SEM) and Bootstrap methods were used to analyze the associations and mediating effects.
Results:
Overall, 71.2% of college students experienced at least one type of ACE, with emotional neglect (40.3%) and emotional abuse ( 25.2 %) having the highest detection rates. The top three HRBs were unhealthy diet (77.8%), physical inactivity (54.1%), and smoking/alcohol use (18.5%). Logistic regression showed that poor family functioning, abuse, and extra familial violence were each associated with an increased risk of smoking/alcohol use ( OR =1.14, 1.11, 1.18) and deliberate self harm ( OR =1.26, 1.19,1.30) (all P <0.05). Experience of abuse increased the risk of high risk sexual behavior and family dysfunction increaded the risk of physical inactivity, respectively ( OR = 1.07 , 1.04, both P <0.05). Mediation analysis revealed that anxiety ( β =0.20) and depression ( β = 0.09 ) partially mediated the pathway from poor family functioning to deliberate self harm; paranoia ( β =0.02) partially mediated the pathway from abuse to high risk sexual behavior; and obsessive-compulsive symptoms ( β =0.26) and depression ( β =0.10) partially mediated the pathway from extra familial violence to deliberate self harm (all P <0.05).
Conclusion
Psychological symptoms play a mediating role in the association between ACEs and HRBs, and mental health interventions may reduce the risk of HRBs among college students.

ObjectiveTo evaluate the detection specificity for clinical samples and the detection capability for standard substances of five commercially available multiplex polymerase chain reaction (PCR) nucleic acid detection kits (hereinafter referred to as the kits) for respiratory pathogens, and to provide a reference for selecting appropriate detection kits for multi-pathogen nucleic acid testing of respiratory infections. MethodsA total of 60 respiratory pathogen-positive clinical samples with known redults were selected and tested using the five kits (labeled as A, B, C, D, and E). The detection rates and Kappa coefficients were calculated to evaluate the consistency between the results from these kits and those from single-pathogen PCR kits. According to the limit of detection (LOD) provided by the kits, standard substances of respiratory pathogens (including 12 types such as influenza virus, Mycoplasma pneumoniae, and Bordetella pertussis) were diluted to four concentrations (250, 500, 1 000, and 2 000 copies·mL⁻¹). All five kits were used for detection to evaluate their respective detection capabilities. ResultsCompared with the results from single-pathogen PCR kits, the five tested kits demonstrated good consistency (all Kappa >0.80). Among them, Kit A had the highest detection rate (100.00%), followed by Kits C and E (98.33%), and then Kits B and D (95.00%). All five kits showed a relatively low false negative rate (FNR) for samples with a cycle threshold (Ct) value ≤35 (≤2.38%). However, for samples with Ct values>35, the FNR increased accordingly(average FNR=6.67%, P=0.029). Kit C exhibited the highest detection sensitivity for the tested standard substances (average LOD: 458.33 copies·mL⁻¹), followed by Kit D, then Kits A/E, and finally Kit B. ConclusionThe five multiplex PCR kits showed good consistency with single-pathogen detection results, but each had its own performance emphasis. Kit A, with the highest detection rate and high throughput, is suitable for targeted viral screening. Kit B, covering the broadest pathogen spectrum (including fungi/bacteria), is suitable for comprehensive respiratory pathogen screening. Kits C, D and E, are applicable for rapid detection. It is important to note that the detection efficacy of all kits decreases for low viral load samples with Ct values >35. In practical application, selection should be based on specific screening objectives, throughput requirements, and sample types.

Uveitis is a blinding inflammatory disease that affects multiple structures within the eye, posing significant risks to patients' vision and mental health. Current treatments mainly involve glucocorticoids and immunosuppressants, which are associated with significant side effects, high relapse rates, and substantial costs. Recent research suggests that the gut microbiota may play a role in the development of uveitis through the gut-eye axis, with related metabolites also influencing disease progression. Modulating the gut microbiota or its metabolites could offer new therapeutic avenues for uveitis. This review explores the relationship between gut microbiota and various uveitis-associated diseases, such as systemic sarcoidosis, Vogt-Koyanagi-Harada syndrome, Behcet's disease, multiple sclerosis, and birdshot chorioretinopathy. It also discusses advancements in microbiota-related therapies, including probiotics and prebiotics, antibiotics, immunomodulators, phage therapy, and fecal microbiota transplantation. The aim is to provide a reference for the development of new therapies targeting specific microbial communities and genetic markers associated with uveitis, thereby promoting the realization of precision medicine.

AIM: To investigate the effects of insulin-like growth factor 1(IGF-1)on the secretion of transforming growth factor β2(TGF-β2), matrix metalloproteinase 2(MMP-2)and hypoxia-inducible factor 1α(HIF-1α)in human scleral fibroblasts(HSF)and their mechanism.METHODS: The cells were cultured with IGF-1 and PI3K/AKT pathway inhibitor LY294002, respectively. CCK-8 method was used to detect cell viability and determine the optimal concentration and time of drug action. Cell migration activity was observed by cell scratch method. To determine the effects of IGF-1 on HSF cells and the regulatory role of PI3K/AKT pathway, HSF cells were divided into control group(without drugs), IGF-1(80 μg/L)group, IGF-1+LY294002(80 μg/L+5 mmol/L)group, and LY294002(5 mmol/L)group, and were cultured for 24 h; the protein expression levels of TGF-β2, MMP-2, HIF-1α, PI3K and AKT were detected by Western blot; the fluorescence expression of TGF-β2, MMP-2 and HIF-1α was detected by cellular immunofluorescence.RESULTS: The results of CCK-8 showed that the cell viability of the 80 μg/L IGF-1 group cultured with different concentrations of IGF-1 was the highest(all P<0.05), and the cell viability of the 80 μg/L IGF-1 group at 24 h was the highest under different culture times. Therefore, the concentration of IGF-1 was selected as 80 μg/L for 24 h. The viability of cells cultured with different concentrations of LY294002 gradually decreased from 6 h(all P<0.05). According to the IC50 value, therefore, the concentration of LY294002 was selected as 5 mmol/L for 24 h. The cell scratch results showed that compared with the control group, the cell mobility of 40 μg/L and 80 μg/L IGF-1 groups was increased(all P<0.05). Compared with the control group, cell mobility in the 2.5 and 5 mmol/L LY294002 groups was decreased(all P<0.05). Western blot results showed that compared with the control group, the protein expressions of TGF-β2, MMP-2, HIF-1α, PI3K and AKT in the IGF-1 group were increased, while those in the LY294002 group were decreased(all P<0.05). Compared with the IGF-1 group, the expression levels of TGF-β2, MMP-2, HIF-1α, PI3K and AKT in the IGF-1+LY294002 group were decreased(all P<0.05). The results of cell immunofluorescence showed that compared with the control group, the fluorescence expressions of TGF-β2, MMP-2 and HIF-1α in the IGF-1 group were increased, while those in the LY294002 group were decreased(all P<0.05). Compared with the IGF-1 group, the fluorescence expressions of TGF-β2, MMP-2 and HIF-1α in the IGF-1+LY294002 group were significantly decreased(all P<0.05).CONCLUSION: IGF-1 promoted the proliferation and migration of human HSF. IGF-1 may up-regulate the expression of TGF-β2, MMP-2 and HIF-1α in HSF through the PI3K/AKT signaling pathway, and participate in the occurrence and development of myopia.

Objective To compare the benefits and drawbacks of primary patch expansion versus pericardial tube right ventricular-pulmonary artery connection in patients diagnosed with pulmonary atresia with ventricular septal defect (PA/VSD). Methods A retrospective study was conducted on patients diagnosed with PA/VSD who underwent primary right ventricular-pulmonary artery connection surgery at our center between 2010 and 2020. Patients were categorized into two groups based on the type of right ventricular-pulmonary artery connection: a pericardial tube group and a patch expansion group. Clinical data and imaging findings were compared between the two groups. Results A total of 51 patients were included in the study, comprising 31 males and 20 females, with a median age of 12.57 (4.57, 49.67) months. The pericardial tube group included 19 patients with a median age of 17.17 (7.33, 49.67) months, while the patch expansion group consisted of 32 patients with a median age of 8.58 (3.57, 52.72) months. In both groups, the diameter of pulmonary artery, McGoon index, and Nakata index significantly increased after treatment (P<0.001). However, the pericardial tube group exhibited a longer extracorporeal circulation time (P<0.001). The reoperation rate was notably high, with 74.51% of patients requiring further surgical intervention, including 26 (81.25%) patients in the patch expansion group and 12 (63.16%) patients in the pericardial tube group. No statistical differences were observed in long-term cure rates or mortality between the two groups (P>0.005). Conclusion In patients with PA/VSD, both patch expansion and pericardial tube right ventricular-pulmonary artery connection serve as effective initial palliative treatment strategies that promote pulmonary vessel development and provide a favorable foundation for subsequent radical operations. However, compared to the pericardial tube approach, the patch expansion technique is simpler to perform and preserves some intrinsic potential for pulmonary artery development, making it the preferred procedure.
