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.

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.

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.

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.

Based on WANG Xugao's “thirty methods of treating the liver”， it is believed that the occurrence and development of childhood tic disorders follow the dynamic progression from liver qi disease to liver fire disease and then liver wind disease. The basic pathogenesis of three stages are characterized by binding constraint of liver qi， liver fire hyperactivity， and internal stirring of liver wind. Moreover， liver-blood deficiency and stagnation， and malnutrition of liver yin as the main point in terms of the imbalance of liver qi， blood， yin， and yang should be considered， as well as the imbalance relationship of the five zang organs such as the involvement of other organs and the gradually reach of the other organs. Guided by the principles of “thirty methods of treating the liver”， the treatment of tic disorders in liver qi stage should focus on soothing the liver and rectifying qi， soothing the liver and unblocking the collaterals， using Xiaochaihu Decoction （小柴胡汤） and Sini Powder （四逆散）. The treatment of tic disorders in liver fire stage involves clearing， draining and resolving liver heat， using Longdan Xiegan Decoction （龙胆泻肝汤）， Xieqing Pill （泻青丸）， Danggui Longhui Pill （当归龙荟丸）， and Huagan Decoction （化肝煎）. The treatment of tic disorders in liver wind stage involves extinguishing wind and subduing yang， using Lingjiao Gouteng Decoction （羚角钩藤汤） and Liuwei Dihuang Pill （六味地黄丸）. Throughout the treatment process， attention should be paid to harmonizing the liver's qi， blood， yin， and yang， as well as addressing the pathology of other organs.

Objective     To explore the correlation between the quantitative and qualitative features of CT images and the invasiveness of pulmonary ground-glass nodules, providing reference value for preoperative planning of patients with ground-glass nodules. Methods    The patients with ground-glass nodules who underwent surgical treatment and were diagnosed with pulmonary adenocarcinoma from September 2020 to July 2022 at the Third Affiliated Hospital of Kunming Medical University were collected. Based on the pathological diagnosis results, they were divided into two groups: a non-invasive adenocarcinoma group with in situ and minimally invasive adenocarcinoma, and an invasive adenocarcinoma group. Imaging features were collected, and a univariate logistic regression analysis was conducted on the clinical and imaging data of the patients. Variables with statistical difference were selected for multivariate logistic regression analysis to establish a predictive model of invasive adenocarcinoma based on independent risk factors. Finally, the sensitivity and specificity were calculated based on the Youden index. Results     A total of 555 patients were collected. The were 310 patients in the non-invasive adenocarcinoma group, including 235 females and 75 males, with a meadian age of 49 (43, 58) years, and 245 patients in the invasive adenocarcinoma group, including 163 females and 82 males, with a meadian age of 53 (46, 61) years. The binary logistic regression analysis showed that the maximum diameter (OR=4.707, 95%CI 2.060 to 10.758), consolidation/tumor ratio (CTR, OR=1.027, 95%CI 1.011 to 1.043), maximum CT value (OR=1.025, 95%CI 1.004 to 1.047), mean CT value (OR=1.035, 95%CI 1.008 to 1.063), spiculation sign (OR=2.055, 95%CI 1.148 to 3.679), and vascular convergence sign (OR=2.508, 95%CI 1.345 to 4.676) were independent risk factors for the occurrence of invasive adenocarcinoma (P<0.05). Based on the independent predictive factors, a predictive model of invasive adenocarcinoma was constructed. The formula for the model prediction was: Logit(P)=–1.293+1.549×maximum diameter of lesion+0.026×CTR+0.025×maximum CT value+0.034×mean CT value+0.72×spiculation sign+0.919×vascular convergence sign. The area under the receiver operating characteristic curve of the model was 0.910 (95%CI 0.885 to 0.934), indicating that the model had good discrimination ability. The calibration curve showed that the predictive model had good calibration, and the decision analysis curve showed that the model had good clinical utility. Conclusion     The predictive model combining quantitative and qualitative features of CT has a good predictive ability for the invasiveness of ground-glass nodules. Its predictive performance is higher than any single indicator.

ObjectiveTo investigate the mechanism of Ershiwuwei Guijiu pill in preventing and treating postmenopausal osteoporosis （PMOP） by activating the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathway and inhibiting excessive autophagy. MethodFemale SD rats were ovariectomized and randomly divided into the sham operation group （Sham）， the operation group （OVX）， the Ershiwuwei Guijiu pill （GJ） group， and the raloxifene hydrochloride （RLX） group， with 10 rats in each group. Enzyme-linked immunosorbent assay （ELISA） and colorimetric methods were used to detect the levels of estrogen， bone metabolism markers in serum， and total superoxide dismutase （T-SOD）， malondialdehyde （MDA）， and glutathione peroxidase （GSH-Px） in tibial tissue. Flow cytometry was used to detect reactive oxygen species （ROS） levels in bone marrow mesenchymal stem cells. Masson staining was used to observe pathological changes in the proximal tibia， and micro-computed tomography （Micro-CT） was used to observe changes in tibial microstructural parameters. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the expression of autophagy-related proteins Beclin1， microtubule-associated protein 1A/1B-light chain 3 （LC3）， autophagy-related 5 （Atg5）， as well as PI3K， Akt， and mTOR in tibial tissue. ResultCompared with the Sham group， the OVX group showed a significant decrease in serum levels of estradiol （E₂） and calcium ion （Ca²⁺）， and T-SOD， GSH-Px， PI3K， Akt， and mTOR mRNA levels in bone tissue （P<0.05， P<0.01）， significantly reduced bone mineral density （BMD）， bone surface/bone volume （BS/BV）， trabecular thickness （Tb.Th）， trabecular number （Tb.N）， and trabecular connectivity （Con） in the tibia （P<0.05， P<0.01）， thinner epiphyseal growth plate， and the bone marrow cavity filled with fat vacuoles. Moreover， the levels of phosphorus （P）， MDA， ROS， and mRNA and protein expression of Beclin1， LC3， and Atg5， as well as trabecular separation （Tb.Sp） were significantly elevated （P<0.05， P<0.01）. Compared with the OVX group， the GJ and RLX groups showed significant increases in serum E₂ and Ca²⁺， and bone tissue levels of SOD， GSH-Px， and the mRNA levels of PI3K， Akt， and mTOR （P<0.05， P<0.01）， significantly increased BMD， BS/BV， Tb.Th， Tb.N， and Con in the tibia， thickened epiphyseal growth plate， and significantly reduced fat vacuoles in the bone marrow cavity （P<0.05， P<0.01）. Additionally， the levels of P， MDA， ROS， Beclin1， LC3， Atg5 mRNA and proteins， and Tb.Sp were significantly decreased （P<0.05， P<0.01）. The ratios of p-PI3K/PI3K， p-Akt/Akt， and p-mTOR/mTOR， which were significantly reduced in the OVX group （P<0.01）， were significantly increased in the GJ and RLX groups （P<0.01）. ConclusionThe Ershiwuwei Guijiu pill reduces oxidative stress and inhibits autophagy， thereby preventing and treating postmenopausal osteoporosis. Its mechanism may be related to the activation of the PI3K/Akt/mTOR signaling pathway， which inhibits autophagy.

Based on the natures and flavors of herbal medicinals recorded in Shen Nong's Classic of the Materia Medica （《神农本草经》）； Miscellaneous Records of Famous Physicians （《名医别录》）， this study analyzed the characte-ristics of the natures， flavors and combination of medicinals of the two-herb compound formulas in Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）.Finally， 31 compound formulas were included， and it was found that the nature and flavor of the herbs in these two-herb compound formulas are closely related to the functions of the compound formulas， such as the common pairing of the acrid and the sweet herbs to warm yang and transform qi， the acrid and the bitter herbs in pairs to regulate and harmonize cold and heat， the sweet and the bitter in pairs to remove dampness and clear heat， the acrid and the acrid in pairs to arrest vomiting and direct qi downward， and the sour and the sweet in pairs to slow the urgent and relieve pain. Regardless of the deficiency or excess nature of the disease， the corresponding two-herb compound formulas often aim to reinforce healthy qi while eliminating pathogenic factors， with some formulas showcasing a unique correspondence between the disease pattern and the symptoms addressed.
