Gout is a systemic inflammatory disease and one of the most common forms of arthritis worldwide. Hyperuricemia is the leading risk factor for gout, with a high incidence rate. The etiology of gout involves the deposition of urate crystals, secondary inflammation, and oxidative stress. These inflammatory and oxidative stress contribute to the pathogenesis of a variety of ocular disorders. Numerous studies have found a correlation of gout and hyperuricemia with ocular diseases, such as direct urate crystal deposition in ocular structures, dry eye syndrome, corneal endothelial damage, scleritis, uveitis, glaucoma, age-related macular degeneration, diabetic retinopathy, and certain metabolic diseases like thyroid-related eye diseases. Furthermore, because of its antioxidant effect, uric acid levels have been linked to a variety of optic neuropathies, including multiple sclerosis-related optic neuritis and neuromyelitis optica. Although the correlation between uric acid levels and ocular diseases has been reported, many aspects remain unresolved. To gain a more thorough understanding of the association between gout, hyperuricemia, and ocular illnesses, this review will delve into their pathogenesis and disease characteristics, aiming to increase knowledge about gout and hyperuricemia and serving as a reference for future studies.

ObjectiveTo evaluate the levels of physical exercise, mental health and social response in children with autism spectrum disorder (ASD), and explore the mediating effect of social response on physical exercise and mental health. MethodsFrom September, 2019 to April, 2024, 211 children with ASD from three special education schools in Haidian District and Shijingshan District of Beijing were selected. They were assessed with general data questionnaire, Physical Activity Rating Scale (PARS-3), Chinese version of Psycho-Educational Profile (C-PEP) and Social Response Scale-Short Form (SRS-SF). The correlation among physical exercise, mental health and social response was analyzed. The mediating effect of social response on physical exercise and mental health was explored. ResultsThe average physical exercise level was (58.72±3.34), the average mental health level was (14.85±1.67), and the average social response level was (24.98±3.79). Physical exercise was positively correlated with mental health (r = 0.546, P < 0.05) and negatively correlated with social response (r = -0.298, P < 0.05). Mental health was negatively correlated with social response (r = -0.397, P < 0.05). Average monthly family income, parental relationship, repeated transcranial magnetic stimulation therapy, physical exercise, social response were the influencing factors of mental health (P < 0.05). Social response was intermediary between physical exercise and mental health, accounting for 14.56%. ConclusionThe mental health level of children with ASD is poor, and there are many influencing factors. Physical exercise can directly affect the mental health of children with ASD, and can also play an indirect role through social response.

Objective To identify flavonoid glycosides with quorum sensing inhibitory activity from Epimedium brevicornum and evaluate their bioactivity. Methods The minimum inhibitory concentrations （MICs） of five major flavonoid glycosides （baohuoside, icariin, epimedin A/B/C） and the extract of E. brevicornum were firstly determined. Subsequently, the inhibitory effects on the production of purple pigments in Chromobacterium violaceum CV026 were measured. Additionally, the biofilm formation and chitin quantification of Pseudomonas aeruginosa PAO1 were assessed. Results The extract of E. brevicornum and its primary components exhibited significant quorum sensing inhibitory activity. Particularly, icariin and epimedin C demonstrated superior inhibitory activity. Conclusion E. brevicornum demonstrates the ability to inhibit the quorum sensing system of Chromobacterium violaceum CV026 and Pseudomonas aeruginosa PAO1. Furthermore, icariin and epimedin C （100 μg/ml） show promise for development into novel drugs for quorum sensing inhibitor.

OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

OBJECTIVE To establish a interview outline design process and quality control evaluation method based on grounded theory， providing ideas for qualitative research interview outline design in medical fields. METHODS A literature review was conducted to understand the current research status； a preliminary interview outline was developed around the research content. The triangulation method， group evaluation， expert review and pre-interview were adopted to execute the interview outline and conduct quality control. The evaluation indicators and target values were formulated （an average score for the overall quality evaluation of all indicators ≥4.5， and an average score for individual indicators ≥4.00） to evaluate the effect of the interview outline. Taking the research on the mechanism of physicians’ prescribing behavior under the background of Diagnosis Related Groups （DRGs） payment as an example， the methodological contents of above interview outline were applied in practical research. RESULTS The interview outline included basic information and interview questions. The interview questions were divided into three parts：influencing factors survey， promoting and hindering factors of standardizing physician prescription behavior， and communication， with a total of 12 questions. After being reviewed by members of the research group， experts review and pre- interview， a total of 9 people participated in the quality control evaluation of the interview outline. The overall evaluation score was 4.94 （＞4.50）， and the average score of each indicator was greater than 4.00， indicating that the quality of the outline met the requirements for the interview and could be used for the formal interview. CONCLUSIONS The established interview outline design and quality control method based on grounded theory provides ideas for the qualitative research interview outline design in the medical field， and lays the foundation for further using grounded theory to study the influencing factors and mechanisms of physician prescription behavior under the DRG background.

In recent years, with the clinical application of minimally invasive surgical techniques and comprehensive preoperative treatment, the survival rate of locally advanced esophageal cancer has significantly improved. However, the treatment of metastatic esophagogastric cancer still relies mainly on systemic therapy, and immunotherapy combined with chemotherapy has become a first-line treatment option, prolonging the survival of patients with metastatic esophageal cancer. Oligometastatic esophageal cancer is expected to bring survival benefits through systemic therapy combined with local treatment. The 2024 European clinical practice guidelines for oligometastatic esophagogastric cancer have been officially released, which standardize the definition, diagnosis, and treatment of oligometastatic esophageal cancer for further prospective studies. The authors interpret this guideline, especially by reviewing the clinical evidence of oligometastatic esophageal squamous cell carcinoma, to provide reference for the diagnosis and treatment of oligometastatic esophageal cancer in China.

Objective: To understand the influence of the concept of movement education on the fundamental motor skills of preschool children aged 3-6, so as to provide a reference for improving the quality of preschool education and promoting the all round development of preschool children. Methods: From August 2022 to June 2023, 592 normally developing preschool children aged 3- 6 in a certain kindergarten in Qingdao were selected as the research objects by convenience sampling. They were randomly divided into the intervention group (physical education activities designed based on the concept of movement education) and the control group (original teaching plan). The intervention lasted for 24 weeks (twice a week, 40 minutes each time). Test of Gross Motor Development-2 (TGMD-2) was used to evaluate the children s gross motor skills, and repeated measures analysis of variance was used to analyze the data of the two groups before and after the intervention. Results: Except for running and kicking, the group main effects ( F group =18.78-104.77), time main effects( F time =243.23-3 003.19), and other interactive effects between group and time ( F group×time =14.01-322.91) were of statistical significances for gross motor, movement motor, manipulative motor and each sub indicator between intervention group and control group. Further simple effect analysis results showed that, before intervention, there were no statistically significant differences in the total scores of gross motor (48.95±10.65,45.87±10.98), movement motor ( 25.93± 7.31,23.46±7.32) and manipulative motor (23.15±4.40,22.40±4.69) between the intervention group and the control group ( F=3.69, 2.94, 1.90, P >0.05); and two goups were also found of no statistical significance in the each sub indicator of movement and manipulative motor ( F=0.01-3.58, P >0.05); after intervention, the total scores of gross motor, movement motor, and manipulative motor in the intervention group (75.92±9.48, 38.12±5.40, 37.80±4.92) were all better than those in the control group ( 59.52± 12.12, 30.71±7.47, 28.81±5.54) ( F =168.15, 97.58, 210.71), and the total indicators of both goups had better scores than those before the intervention ( F intervention = 3 498.90 , 1 438.27, 2 431.24; F control =545.58, 309.18, 283.29)(all P <0.01); after intervention, the intervention group had better scores in all sub indicators (except for running and kicking) than the control group ( F =43.57-297.71), and the each sub indicator of both goups had better scores than those before the intervention ( F intervention = 300.58-858.65; F control =12.28-135.64)(all P <0.01). Conclusion Physical education activities designed based on the concept of movement education could better promote the development of children s fundamental motor skills.

HDAC7, a member of class IIa HDACs, plays a pivotal regulatory role in tumor, immune, fibrosis, and angiogenesis, rendering it a potential therapeutic target. Nevertheless, due to the high similarity in the enzyme active sites of class IIa HDACs, inhibitors encounter challenges in discerning differences among them. Furthermore, the substitution of key residue in the active pocket of class IIa HDACs renders them pseudo-enzymes, leading to a limited impact of enzymatic inhibitors on their function. In this study, proteolysis targeting chimera (PROTAC) technology was employed to develop HDAC7 drugs. We developed an exceedingly selective HDAC7 PROTAC degrader B14 which showcased superior inhibitory effects on cell proliferation compared to TMP269 in various diffuse large B cell lymphoma (DLBCL) and acute myeloid leukemia (AML) cells. Subsequent investigations unveiled that B14 disrupts BCL6 forming a transcriptional inhibition complex by degrading HDAC7, thereby exerting proliferative inhibition in DLBCL. Our study broadened the understanding of the non-enzymatic functions of HDAC7 and underscored the importance of HDAC7 in the treatment of hematologic malignancies, particularly in DLBCL and AML.
