ObjectiveTo investigate the effect of interfering with long noncoding RNA (LncRNA) small nucleolar RNA host gene16 (SNHG16) on improving angiogenesis of ectopic endometrial stromal cells (EScs) in adenomyosis (AM) by targeting upregulation of miRNA (miR)-141-3p and inhibition of high mobility group box-1 protein (HMGB1). MethodsThe expression levels of SNHG16, miR-141-3p and HMGB1 mRNA in endometrial tissues of 52 patients with adenomyosis (AM group) and 52 patients who needed hysterectomy due to cervical cancer or ovarian cancer (control group) were detected by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Y14 cells were divided into small hairpin RNA (shRNA) NC group, shRNA SNHG16 group, shRNA SNHG16+miR-141-3p inhibitor (inhibitor) group, shRNA SNHG16+inhibitor NC group and blank group. The targeting relationship between miR-141-3p and SNHG16 as well as HMGB1 was verified. The expression levels of SNHG16, miR-141-3p and HMGB1 mRNA in Y14 cells were detected by qRT-PCR. CCK-8 and Transwell assay were used to detect cell proliferation, invasion and migration. Microvascular density (MVD) was determined by immunofluorescence. The expressions of hypoxia-inducing factor α (HIF-1α), cyclooxygenase-2 (Cox-2), vascular endothelial growth factor (VEGF) and HMGB1 were detected by Western blot. ResultsThe expression of SNHG16 and HMGB1 mRNA in AM group was higher than that in control group, but the expression of miR-141-3p was lower than that in control group (P0.05). The expression of SNHG16, HMGB1 mRNA, proliferation rate, migration, invasion number, MVD, expression of VEGF, HIF-1 α, Cox-2, and HMGB1 proteins in the shRNA SNHG16 group were lower than those in the blank group and shRNA NC group, while the expression of miR-141-3p was higher than that in the blank group and shRNA NC group (P0.05). Inhibition of miR-141-3p reversed the improvement of EScs angiogenesis by interfering with SNHG16. ConclusionInterference with LncRNA SNHG16 improves EScs angiogenesis and inhibits proliferation, migration, and invasion of EScs by targeting upregulation of miR-141-3p and inhibition of HMGB1.

Intravitreal anti-vascular endothelial growth factor(anti-VEGF)therapy has been widely used, but the variability in its therapeutic efficacy limits individualized treatment. In recent years, the application of artificial intelligence(AI)has opened up new avenues for personalized treatment response prediction, and its core branches include machine learning(ML)and deep learning(DL). This review systematically retrieved and analyzed 41 relevant studies published up to April 2025. Comprehensive analysis reveals that AI predictive models are evolving from forecasting single endpoints(such as visual acuity or central retinal thickness)to integrating multi-dimensional endpoints(encompassing anatomical, functional, and treatment demand parameters)and generating predictive imaging outputs. In terms of technical approaches, DL models(28 studies, accounting for 68.3%)dominate this field due to their robust image interpretation capabilities, while ML models(10 studies, 24.4%)retain significant value in the analysis of structured clinical data. Cross-disease comparisons indicate that research efforts are most concentrated on age-related macular degeneration(ARMD)and diabetic macular edema(DME), with shared conceptual frameworks for model construction, yet distinct anatomical and functional indicators are prioritized for each disease. Currently, the field confronts several key challenges, including insufficient prospective clinical validation, limited model interpretability(the “black box problem”), and a scarcity of high-quality multi-center datasets. Moving forward, it is imperative to advance real-world validation and develop explainable AI techniques to expedite the clinical translation of these predictive models.

Objective:
To understand the epidemiological characteristics and disease burden of influenza like illness (ILI) among student populations, so as to provide data support for policy formulation and optimal allocation of health resources.
Methods:
From January 2024 to February 2025, a questionnaire survey was conducted among parents of kindergarten, primary school, junior and senior high school students in 9 districts of Shenzhen, including Longhua, Futian, Bao an, Longgang, Luohu, Nanshan, Guangming, Pingshan and Yantian. Parents were asked to complete the questionnaire based on whether their children had fever, cough, vomiting, diarrhea, rash and other common symptoms in 2024. A total of 3 537 parents were investigated, and 444 ILI cases were included as study subjects. The epidemiological burden, including incidence rate of influenza, visitation rate, years lived with disability (YLDs) and economic burden (including direct economic burden, indirect economic burden and intangible burden) were analyzed.
Results:
The incidence rate of influenza among students in Shenzhen in 2024 was 12.55%. The ILI incidence rates in kindergarten, primary school, junior and senior high school were 14.01%, 11.69% and 5.23%, respectively, with a statistically significant difference ( χ 2= 45.20, P <0.01). The ILI consultation rate among students was 85.36%, and the consultation rates in kindergarten (87.36%) and primary school students (84.62%) were higher than those in junior and senior high school students ( 56.52 %) ( χ 2=16.47, P <0.01). A total of 78.88% of cases did not receive etiological detection.The median total economic burden per ILI case was 2 354.62 yuan, including direct medical costs of 300.00 yuan, direct non medical costs of 212.50 yuan, indirect costs of 1 000.00 yuan, and intangible burden of 500.00 yuan.
Conclusions
Schools are high risk environment for influenza, and younger students are a high risk group for ILI. The disease burden caused by student ILI remains substantial.
4.Expert recommendations on vision friendly built environments for myopia prevention and control in children and adolescents
Chinese Journal of School Health 2026;47(1):1-5
Abstract
The prevention and control of myopia in Chinese children and adolescents has become a major public health issue. While maintaining increased outdoor activity as a cornerstone intervention, there is an urgent need to explore new complementary approaches that can be effectively implemented in both indoor and outdoor settings. In recent years, environmental spatial frequency has gained increasing attention as one of the key environmental factors influencing the development and progression of myopia. Both animal studies and human research have confirmed that indoor environments lacking mid to high spatial frequency components, often characterized as "visually impoverished", can promote axial elongation and myopia through mechanisms such as disruption of retinal neural signaling, impaired accommodative function, and altered expression of related molecules. Based on the scientific consensus, it is recommended that "enriching of environmental spatial frequency" should be integrated into the myopia prevention and control framework. Following the principles of schoolled organization, family cooperation, community involvement, and student participation, specific measures are put forward in three areas:optimizing school visual settings, improving home spatial environments, and promoting healthy visual behavior. The aim is to create "visually friendly" indoor environments as an important supplement to outdoor activity, thereby providing a novel perspective and strategy for comprehensively advancing myopia prevention and control among children and adolescents.

Acute esophagogastric variceal bleeding (AEGVB) is one of the life-threatening complications of decompensated cirrhosis. Endoscopy is the main method for the diagnosis and treatment of AEGVB, and endoscopic treatment can effectively control acute bleeding and alleviate or eliminate varices. However, there is still a lack of consistent recommendations for the timing of endoscopic examination and intervention for AEGVB in related guidelines in China and globally. Existing studies in China and globally have low quality of evidence, with significant variations in the definition of “early endoscopy” and inconsistent conclusions. This article reviews the research advances in the timing of endoscopic treatment for AEGVB in liver cirrhosis, points out the controversies over the optimal timing of treatment, and discusses future research directions in this field.

Objective To explore the efficacy and safety of blue laser vaporization in the treatment of large-volume (>80 mL) benign prostatic hyperplasia (BPH). Methods A retrospective analysis was conducted on the clinical data of 149 BPH patients with prostate volume>80 mL who underwent blue laser vaporization at our hospital during Aug. 2023 and Aug. 2025. The 1-month postoperative maximum urinary flow rate (Qmax) and international prostate symptom score (IPSS), operation time, postoperative hemoglobin drop, bladder irrigation volume, catheter indwelling time, and incidence of postoperative complications were recorded and analyzed. Results All operations were successfully completed, without conversion to other approaches. The operation time was (41.47±11.05) minutes, postoperative hemoglobin drop (2.78±1.19) g/L, bladder irrigation volume (9.97±1.49) bags, and catheter indwelling time (3.30±1.85) days. One month after surgery, the Qmax was significantly higher than the preoperative value [(20.19±3.39) mL/s vs. (2.39±2.17) mL/s], while the IPSS was significantly lower [(4.46±0.87) vs. (27.69±2.06)], with statistically significant differences (P<0.001). Postoperative complications included 1 case of incontinence (0.67%), 2 cases of urethral stricture/bladder neck contracture (1.34%), and 1 case of secondary bleeding (0.67%), all of which improved with symptomatic treatment. Conclusion Blue laser vaporization is effective for treating large-volume BPH, with advantages such as minimal bleeding risk, short operation time, fast recovery and safety.

ObjectiveTo investigate the urate-lowering effect of Shenling Qushi prescription in the mouse model of hyperuricaemia. MethodsSixty-three C57BL/6N mice were randomly assigned to the following groups (n=9): Control, model, low-dose (6 g·kg-1) Shenling Qushi prescription, medium-dose (12 g·kg-1) Shenling Qushi prescription, high-dose (24 g·kg-1) Shenling Qushi prescription, medium-dose Shenling Qushi prescription plus febuxostat (12+0.003 g·kg-1), and febuxostat (3 mg·kg-1). A mouse model of persistent hyperuricaemia was established via intraperitoneal injection of potassium oxazolamide (250 mg·kg-1) combined with oral administration of allopurinol (300 mg·kg-1) over a 28-day period. Concurrently, the prescription was administered orally at the specified doses once daily for 21 consecutive days. Throughout the experiment, mouse body weight, food intake, water consumption, and urine output were measured and recorded. Kidney and liver indices were calculated. Renal histopathological changes were observed by haematoxylin and eosin staining. Serum uric acid (SUA) and urinary uric acid (UUA) levels, along with xanthine oxidase (XOD) and adenosine deaminase (ADA), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, were determined. Real-time PCR was employed to assess the mRNA levels of urate anion transporter 1 (URAT1) and glucose transporter 9 (GLUT9) in the renal tissue, alongside those of XOD and ADA in the liver tissue. The protein levels of URAT1 and GLUT9 in the renal tissue were determined by Western blot. ResultsCompared with the normal group, model mice exhibited reduced food intake and body weight (P<0.01), decreased water consumption yet increased urine output, no significant change in the liver index but increased kidney index (P<0.01). Pathological findings revealed renal tissue damage including glomerular atrophy, epithelial cell detachment, and inflammatory cell infiltration. Furthermore, the model group exhibited elevated UUA and SUA levels (P<0.01), enhanced activities of ALT, AST, XOD, and ADA in the liver tissue (P<0.05, P<0.01), upregulated mRNA and protein levels of URAT1 and GLUT9 in the renal tissue (P<0.05), alongside markedly elevated mRNA levels of XOD and ADA in the liver (P<0.01). Compared with the model group, the Shenling Qushi prescription groups showed no significant changes in body weight or food intake, with water consumption and urine output remaining within normal ranges, alleviated glomerular atrophy, with reduced pathological damage such as inflammatory infiltration, declined UUA and SUA levels (P<0.01), and increased activities of ALT, AST, XOD, and ADA in the serum (P<0.01). Real-time PCR results demonstrated that Shenling Qushi prescription downregulated the mRNA levels of URAT1 and GLUT9 in the renal tissue (P<0.05, P<0.01) and XOD and ADA in the hepatic tissue (P<0.05, P<0.01). Western blot results demonstrated Shenling Qushi prescription reduced the protein levels of URAT1 and GLUT9 (P<0.05, P<0.01). ConclusionShenling Qushi prescription modulates fluid balance and reduces uric acid levels, thereby alleviating renal injury in hyperuricaemic mice. This effect is highly likely mediated through inhibition of uric acid synthesis and reabsorption.

Against the backdrop of digital transformation in higher education, the traditional teaching model has become inadequate to meet the demands for cultivating new-quality nursing talents. Nursing ethics teaching confronts several dilemmas, such as unbalanced regional development, disconnection between theory and practice, scattered teaching resources, and fragmented knowledge points. With the iterative update of modern digital technologies, the knowledge graph, due to its structured, semantic, scalable, and multi-source integrative characteristics, offers a technological pathway to address these issues. Based on the construction foundation of the Ministry of Education’s first batch of virtual teaching and research platforms for humanistic nursing courses, the nursing ethics artificial intelligence(Al)course was developed around the“thinking-research-teaching-learning”framework. By strengthening ideological and political guidance, constructing a curriculum knowledge graph, and promoting the deep integration of humanistic care and professional knowledge,the course realized intelligent support for research,learning,and teaching. This innovative education model provides a replicable paradigm for cultivating outstanding nursing talents equipped with humanistic literacy, digital competence, and advanced ethical thinking, while also offering references for the digital transformation of higher nursing education.

Chinese Journal of Biologicals 2026;39(10):1205-1212
Objective To develop and verify a reversed-phase high-performance liquid chromatography(RP-HPLC) method for quantifying biotin residues in human papillomavirus(HPV) vaccines, thereby providing data support for the research on the removal ability of biotin in the downstream production process of HPV vaccines.Methods Chromatographic parameters were systematically optimized, including mobile phase composition, elution gradient, and temperature controls. A RP-HPLC method for the determination of biotin residues in HPV vaccines was developed, and was verified for system suitability, specificity, linearity, accuracy, precision, limit of detection(LOD), limit of quantitation(LOQ), and robustness in strict accordance with the Guideline for Analytical Method Validation(General Chapter 9101) of the Chinese Pharmacopoeia(Vol Ⅲ, 2025edition). The validated method was subsequently applied to detect biotin residues in the in-process samples and bulk solution samples of quadrivalent HPV vaccines.Results The optimized chromatographic conditions were as follows: the column was Luna C18~??100??(4. 6 mm × 250 mm, 5 ??m); the mobile phase A, B and C were water, acetonitrile and 0. 1% trifluoroacetic acid(TFA) respectively with ternary gradient; the flow rate was 1 mL/min, with detection at 200 nm, column temperature at35 ℃, autosampler temperature at 25 ℃, and an injection volume of 100 ??L. The method exhibited good system applicability and specificity. The biotin showed a good linear relationship in the concentration range of 0. 312 5-5 ??g/mL(R~2= 1).The average recovery rate of high-, medium-, and low-concentration(4, 1. 5, 0. 5 ??g/mL) biotin quality control(QC) samples was 100. 28%. The relative standard deviations(RSDs) of repeatability test results for low-concentration biotin QC samples were ≤ 5%. The RSDs of intermediate precision test results for low-concentration biotin QC samples prepared over three days were ≤ 5%, the LOQ was 0. 312 5 ??g/mL, and the LOD was 0. 156 ??g/mL. The RSDs of the test results of low-concentration biotin QC samples stored at 25 ℃ for 0, 24 and 48 h were ≤ 5%, indicating good stability. No biotin residues were detected in either in-process samples or bulk solution samples of three batches of quadrivalent HPV vaccines by using this method.Conclusion A RP-HPLC method for the determination of biotin residues was established. This method exhibits excellent performance and is suitable for the investigation of biotin residues in quadrivalent HPV vaccines.

Objective:To evaluate the safety and effectiveness of physician modified stent grafts technique and in situ fenestration technique for reconstructing the left subclavian artery in endovascular repair of thoracic aortic lesions with insufficient proximal landing area.Methods:A retrospective analysis was conducted on the clinical data of 75 patients with aortic arch lesions treated with physician modified stent grafts and in situ fenestration techniques at the Interventional Diagnosis and Treatment Department of Beijing Anzhen Hospital affiliated with Capital Medical University from November 2021 to March 2024. Among them, 52 patients received within physician modified stent grafts (PMSGs group) and 23 patients received in situ fenestration (ISF group). Based on two fenestration techniques, to analyze the technical success rate of endovascular repair in reconstructing the left subclavian artery in the perioperative and early following up adverse events both groups.Results:The success rate of PMSGs group technique was 92.31% (48/52), while the success rate of ISF technique was 91.30%(21/23). In the PMSGs group, there was 1 case of TypeⅠa endoleak and 3 cases of TypeⅠc endoleak immediately during endovascular repair; There was 1 case of TypeⅠa endoleak and 1 case of vascular injury in the ISF group immediately during endovascular repair. One case of perioperative cerebral infarction and one case of transient blindness occurred in the PMSGs group; One case of transient blindness and 1 case of brachial artery thrombosis occurred in the perioperative period in the ISF group. During the follow-up period, there was 1 case of distal dissection aneurysm formation in the PMSGs group, and 3 cases of minor typeⅠc endoleak were found after 3 months; One case of subclavian artery stent occlusion and 2 cases of minor typeⅠc endoleak occurred in the ISF group 6 months later. There were no cases of aortic-related deaths during the follow-up period in both groups. There was no statistically significant difference in the technical success rate, incidence of adverse events during the perioperative period and follow-up period, and re-intervention rate between the two groups. The average fluoroscopy time consumed in the ISF group was significantly higher than that in the PMSGs group (34.57 min vs. 21.42 min, P<0.001), but the average hospitalization time in the PMSGs group was significantly higher than that in the ISF group (9.33 days vs. 4.71 days, P<0.001). Conclusion:PMSGs and ISF techniques for reconstructing the left subclavian artery in the treatment of thoracic aortic arch lesions showed good safety and effectiveness. The appropriate fenestration technique selected based on aorta arch anatomical and lesion conditions could achieve satisfactory efficacy in short-term, but long-term effects need to be further observed.
