AIM: To investigate the influencing factors of stereoscopic function reconstruction after intermittent exotropia(IXT)surgery and the construction of a nomogram prediction model.METHODS:A total of 204 patients with IXT(all underwent strabismus correction surgery)admitted to our hospital from September 2021 to October 2023 were randomly divided into modeling group(143 cases)and validation group(61 cases). The patients in the modeling group were further divided into reconstructive group and non-reconstructive group according to whether they had stereoscopic function reconstruction after surgery; the general patient information was collected; Multivariate Logistic regression analysis was performed on the influencing factors of stereoscopic visual function reconstruction after IXT surgery. The nomogram model was constructed using R software. The ROC curve was drawn to evaluate the distinction of the nomogram model. The decision curve analysis(DCA)was used to evaluate the clinical application value of the model.RESULTS:Reconstruction occurred in 50.5%(103 cases)of the 204 patients, and reconstruction occurred in 50.3%(72 cases)of the 143 patients in the modeling group. There were differences in age of onset, course of disease and postoperative horizontal strabismus between the reconstructive group and the non-reconstructive group(all P<0.05). Multivariate Logistic regression analysis showed that age of onset and postoperative horizontal strabismus were risk factors for stereoscopic visual function reconstruction after IXT surgery(all P<0.05), and the course of disease was a protective factor(P<0.05). The AUC of the modeling group was 0.892, and the H-L test was χ2=6.654 and P=0.615. The AUC of the validation group was 0.935, and the H-L test was χ2=6.498 and P=0.642. The DCA curve showed that the clinical value of the nomogram model was higher when the probability was 0.09-0.95.CONCLUSION: The age of onset, course of disease and postoperative amount of horizontal strabismus are the influencing factors of stereoscopic visual function reconstruction after IXT surgery, and the nomogram model constructed by this can better predict postoperative stereoscopic function reconstruction.

Objective:To evaluate the effect and causality of serum metabolites on the pathogenesis of ulcerative colitis (UC), so as to provide reference for nutritional programs for patients with UC.Methods:Two-sample Mendelian randomization (MR) analysis was performed to estimate the causal relationship between serum metabolites and UC. Genome-wide association studies (GWAS) of 1 400 metabolites were performed, with the metabolites as exposure and UC as outcome. Inverse-variance weighted (IVW) was used to calculate causal estimates. Four other MR methods with different modeling assumptions including MR-Egger, weighted median, weighted mode, and simple mode were used as additional analyses to improve the stability of the results. The results were validated through heterogeneity and pleiotropy tests. Finally, the possible causal metabolites were analyzed by metabolic pathway analysis.Results:MR analysis revealed that 85 metabolites had a possible causal relationship with UC. Among them, phosphatidylglycerol 1,2-dipalmitoyl-gpc (DPPC) ( P=2.75×10 -6) and isovaleryl carnitine (C5) ( P=1.84×10 -5) were significant risk factors for UC. Metabolic pathway analysis identified 5 metabolic pathways that might be affected by these metabolites (all P<0.05), among which the porphyrin ( P=0.004) and pyrimidine metabolic pathways ( P=0.008) had higher confidence in impacting UC. Conclusions:There are causal relationships between some serum metabolites (in particular 1,2-dipalmitoyl-GPC and isovalerylcarnitine) and the risk of UC. The porphyrin and pyrimidine metabolic pathways may impact the pathogenesis of UC.

In terms of the complexity of the"left"and"right"concepts,these directional terms not only indicate spatial orientation but also embody hierarchical order,official titles,systemic imbalances,and temporal sequences.This study explains the medical theory of"liver is born on the left and lung is hidden on the right,"and reveals its implications for ascending and descending of qi movement pathways,sequential patterns,non-equilibrium states,and the centrality of the middle,thus linking the connotation of this theory and its application.In view of this,the theory of"liver is born on the left and lung is hidden on the right"can be used in the clinical diagnosis and treatment of qi-blood-body fluid and emotional diseases,and guides disease prevention and treatment,as well as enhances the subjective initiative of health maintenance and longevity.This study not only deepens the modern interpretation of the classical theory but also provides novel perspectives for its application in disease prevention and treatment.

Objective:To explore the factors influencing healthcare-seeking time in diabetic foot patients and to develop and validate a predictive model for healthcare-seeking time.Methods:A total of 299 diabetic foot patients hospitalized in the Department of Endocrinology and Metabolism at the First Affiliated Hospital of Zhengzhou University from March 2023 to January 2024 were recruited for model development and internal validation. Sixty additional patients from the Second Affiliated Hospital of Zhengzhou University from September 2023 to January 2024 were used for external validation. Kaplan-Meier survival curves were used to estimate healthcare-seeking times. Cox regression analysis identified influencing factors and constructed the model. Random Survival Forest (RSF) was employed for variable selection and model construction. Internal validation was conducted using 10-fold cross-validation, and model evaluation utilized the integrated Brier score, C-index, and prediction error curve. Results:Kaplan-Meier analysis revealed that education level, foot self-care ability, lower extremity vascular disease, and disease perception significantly influenced healthcare-seeking time ( P<0.05). Cox regression identified gender, income level, medical payment method, living situation, marital status, ulcer history, social support, disease perception, and healthcare behavior perception as significant influencing factors ( P<0.05). RSF variable selection indicated that social support, disease perception, e-health literacy, healthcare behavior perception, and age were the most valuable factors for model construction. In external validation, the Brier scores for the Cox regression and RSF models were 0.059 and 0.088, respectively, while the C-indices were 0.862 and 0.683. Prediction error curves showed that the Cox regression model had lower prediction errors and higher predictive performance. Conclusions:The Cox regression model demonstrated superior performance and can assist nurses in effectively identifying high-risk populations for delayed healthcare-seeking in diabetic foot patients. This allows for timely interventions to improve healthcare behavior and reduce delays.

Objective To compare the efficacies of allogeneic hematopoietic stem cell transplantation(allo-HSCT)in the treatment of post-chronic aplastic anemia(CAA)myelodysplastic syndrome(MDS)and primary MDS.Methods A retrospective analysis was conducted on 32 patients who received allo-HSCT treatment in Department of Hematology,North China University of Science and Technology Affiliated Hospital between Feb.2012 and Feb.2022,including 12 patients with post-CAA MDS and 20 patients with primary MDS.The overall survival rate,cumulative incidence of relapse(CIR)rate,non-relapse mortality(NRM)rate,and event-free survival rate were compared between the 2 groups.Results The median follow-up time for CAA to progress to MDS was 120(72-180)months.All the patients were followed up for 36(3-79)months after allo-HSCT.The 3-year overall survival rate of the post-CAA MDS group was significantly higher than that of the primary MDS group(83.8%vs 45.0%,P=0.035).The 3-year CIR of the post-CAA MDS group was significantly lower than that of the primary MDS group(16.7%vs 55.0%,P=0.021).There was no significant difference in the event-free survival rates or NRM rates between the 2 groups(both P＞0.05).Conclusion The post-CAA MDS patients have better survival after allo-HSCT than the primary MDS patients.Early allo-HSCT treatment may improve the prognosis.

Objective To analyze the clinical characteristics and prognosis of patients with spon-taneous coronary artery dissection(SCAD).Methods A retrospective analysis was conducted in 40 patients with acute myocardial infarction(AMI).All patients were diagnosed with SCAD during hos-pitalization through coronary angiography(CAG)or intravascular ultrasound(IVUS).The clinical characteristics,CAG or IVUS findings,and treatment regimens of the patients were analyzed,and their prognosis was assessed through follow-up.Results Among 40 SCAD patients,there were 11 males and 29 females,with a mean age of(53.04±9.15)years.Twelve patients had identified causative factors,and seven patients presented with chest pain as the initial symptom.CAG or IVUS results showed that a total of 69 SCAD lesions were detected in 40 patients,with 15 patients having a single lesion.The primary treatment approach for the patients was medical therapy.The median fol-low-up duration was 34 months(ranging 2 to 48 months),during which 5 major adverse cardiovascu-lar and cerebrovascular events(MACCE)occurred.The patients were divided into MACCE group(5 patients)and non-MACCE group(35 patients)based on occurrence of MACCE.The mean age and the incidence of regional wall motion abnormalities on echocardiography were higher in the MACCE group than in the non-MACCE group(P＜0.05).Conclusion SCAD has distinct imaging features on CAG,and IVUS can confirm the diagnosis.Most patients are treated with medical therapy and have a generally favorable prognosis.However,patients with older age or regional wall motion abnormali-ties on echocardiography have poorer prognosis.

Objective: To explore the short-term improvement effect of physical exercise and cognitive training on inhibitory control function of college students, and to clarify the temporal quantitative-effectiveness relationships between long-term exercise-integrated cognitive interventions and inhibitory control function of college students, in order to provide a reference for promoting inhibitory control function in this population. Methods: College students from Tianjin University of Sport were recruited in May 2022 to participate in the intervention study, which included both short-term and long-term interventions. The short-term intervention used a 2 (physical exercise: yes，no) × 2 (cognitive training: yes，no) between-groups design, with 69 participants randomized into a movement integration cognitive group ( n =18)，a physical exercise group ( n =16)，a cognitive training group ( n =17)，and a control group (sedentary viewing of a health information video, n =18)，for a 30 min intervention.The long term intervention used a mixed experimental design with a 2 (intervention groups; intervention group，control group, between-group variable) ×5 (intervention time: pre-test, 1 week, 4 weeks, 6 weeks, and 8 weeks, within-group variable) mixed experimental design with 24 participants, including 13 in the intervention group，who underwent the exercise-integrated cognitive intervention for 30 min, 3 times per week, and 11 in the control group, who maintained their daily activities without the intervention. The main effects of the independent variables and their interactions were analyzed using covariance and repeated measures ANOVA. Results: There was a statistically significant interaction between physical exercise and cognitive training on accuracy of the Flanker task for the short intervention[ F (1,64) =7.05, P =0.01, η 2 P=0.10], and the simple effect test showed that cognitive training reduced accuracy of responses in the presence of physical exercise condition( P =0.02), and the main effect of physical exercise among college students was significant for the reaction time [ F (1,65) =14.12, P < 0.01 , η 2 p =0.18]; for Flanker task reaction time in the long-term intervention, the main effect of intervention time was significant[ F (4,19) = 3.03 , P =0.04, η 2 P =0.39].However, the intervention results of 1, 4, 6 and 8 weeks in the intervention group [(28.13±10.32)( 14.14 ±26.98)(13.54±25.61)(15.14±21.34)ms] were all better than the pre-test [(77.54± 39.34 )ms], the main effect of intervention group was significant [ F (1,22) =6.96, P =0.02, η =0.24]. Conclusion In a short-term intervention for inhibitory control function in college students, physical exercise is more effective than cognitive training; long-term exercise and cognitive training can improve the inhibitory control function of college students.
