ObjectiveTo explore the function and related molecular mechanisms of magnoflorine against colon cancer via network pharmacology， molecular docking， and in vitro cell experiments. MethodsIn this study， the canonical SMILES of magnoflorine was obtained from the PubChem database， and the potential targets of magnoflorine were predicted by the Swiss Target Prediction database， while the disease targets of colon cancer were obtained from the DisGeNET， GeneCards and OMIM databases. The intersecting targets between magnoflorine's predicted targets and colon cancer disease targets were taken， and a protein-protein interaction （PPI） network was constructed and analyzed. The DAVID online database was employed to conduct Gene Ontology （GO） and KEGG pathway enrichment analyses on core targets. The top five key targets screened were docked with magnoflorine using AutoDock software. Finally， cellular experiments including CCK-8 assays， EdU experiments， cell scratch assays， and Transwell assays were conducted to validate the results from network pharmacology and molecular docking. Results44 key targets of magnoflorine in resisting colon cancer were acquired. The molecular docking results showed that magnoflorine had a strong binding activity with the core target signal transducer and activator of transcription 3 （STAT3） in the top five of the PPI network. Cellular experiments confirmed that magnoflorine could inhibit the proliferation and migration of colon cancer cells by suppressing the JAK/STAT3 signaling pathway. ConclusionMagnoflorine may inhibit the proliferation and migration of colon cancer cells by regulating the JAK/STAT3 signaling pathway.

Objective: This study aimed to systematically evaluate potential causal relationships between nine cathepsins and female infertility using Mendelian randomization (MR) methods. Methods: A bidirectional MR analysis was conducted utilizing single nucleotide polymorphisms as instrumental variables to investigate the potential causal effects between nine cathepsins and female infertility. Genetic data on female infertility were sourced from the FinnGen study, and cathepsin-related data were obtained from genome-wide association studies datasets of European ancestry. Results: Elevated levels of cathepsin E were significantly and inversely associated with the risk of female infertility, suggesting a potential protective role. This finding was further supported by multivariable MR analysis. However, no significant associations were observed between the other eight cathepsins and female infertility. Conclusion This study represents the first systematic MR analysis to identify a potential protective effect of cathepsin E on female infertility.

Objective:To establish a set of dynamic definition methods and key operational techniques for community pediatric services contents within the framework of an integrated children health services model.Methods:This was a cross-sectional study. From December 2023 to June 2024, a study was conducted at the Shanghai Gumei Community Health Service Center. The study was divided into three phases: identifying the health needs of community children (Phase A), developing the service content and methods for community children (Phase B), and establishing a community children service network (Phase C). A variety of methods, including questionnaires and focus group interviews, were comprehensively employed in each phase to develop the ABC demand network and its construction approach for community children, and to establish a networked service system.Results:A total of 512 questionnaires were distributed in Phase A, of which 499 were returned for an effective recovery rate of 97.5%. Of the parents, 488 (97.8%, 488/499) would actively seek information related to children′s health. Of those parents, 90.6% (452/499), 80.8% (403/499), and 71.9% (359/499) expressed concern about their children′s growth and development, mental health and social adaptation, and the prevention and treatment of common, frequently occurring diseases, respectively. The research clarified the health needs of children in the community and the health issues of children in different age groups. This included the mental health and social adaptation of community children, as well as common and frequently occurring diseases. The study also revealed a lack of mental health and social adaptation's services for children in the community. After sorting the community′s services into categories such as children′s growth and development detection, diagnosis and treatment of common diseases, and planned immunizations, and establishing corresponding service methods, it was found that Gumei community Health Service Center had strong diagnostic service capabilities for children aged 0-3 and 4-6, but need improved for children aged 7-12 and 13-15. At the same time, a service network consisting of five major categories, represented by medical alliances, has been established to address unmet needs in diagnosis and rehabilitation care for mental health and social adaptation, as well as major diseases.Conclusions:The study has developed an ABC demand network and its construction method for community children. It provides new ideas for defining the content of community pediatric services and establishing supporting methods, and it offers a practical basis for the constructing a community pediatric service system.

Objective:To investigate the pulmonary function in patients with Parkinson's disease(PD)and the association between pulmonary function and motor symptoms.Methods:A total of 104 PD patients were included in the study,and a portable spirometer was used to assess pulmonary function.According to the results of pulmonary function,the patients were divided into ventilation dys-function group with 37 patients and non-ventilation dysfunction with 67 patients,and clinical data were compared between the two groups.Univariate and multivariate logistic regression analyses were used to investigate the factors associated with abnormal pulmonary function,and a Spearman correlation analysis was used to investigate the correlation between pulmonary function parameters and motor symptoms.Results:There were significant differences in the scores of bradykinesia and postural gait between the two groups(P<0.05),and the logistic regression analysis showed a positive correlation between pulmonary ventilation dysfunction and postural gait score(regression coefficient β=0.171,95%CI=1.015-1.386,P=0.032).There were significant differences between the patients with different stages of PD in the pulmonary function parameters of the percentage of forced vital capacity in predicted value(t=2.143,P=0.034),the percentage of forced expiratory volume in 1 second(t=2.118,P=0.037),the percentage of predicted peak expiratory flow(t=2.002,P=0.048),maximum expiratory pressure as a percentage of predicted value(t=2.412,P=0.018),and maximum inspiratory pressure as a percentage of predicted value(t=2.119,P=0.036).Conclusion:The pulmonary function parameters of PD patients are lower than expected values,and the incidence rate of pulmonary ventilation dysfunction is 35.58%,with the main manifestation of restrictive ventilatory dysfunction.There is a correlation between pulmonary function and motor symptoms in PD patients.

Objective:To explore clinical and genetic features of persistent asymptomatic microscopic hematuria in children.Methods:A retrospective case analysis of 135 individuals admitted to Xi ′an Children′s Hospital with persistent asymptomatic microscopic haematuria between January 2016 to December 2023 was conducted. The demographic characteristics, kidney pathology and gene results of 135 individuals were analyzed. One hundred and thirty-five individuals were divided into 2 groups (positive group and negative group) according to family history of glomerulogenic hematuria in first-degree relatives. The differences of hematuria remission, proteinuria and gene variation were compared between the 2 groups. Two independent sample t test, Wilcoxon rank sum test, Pearson Chi-square, Yates′ corrected Chi-squared test or Fisher exact test were used for comparison between groups. Results:All 135 children, with 48 males and 87 females, were 8.5 (6.5, 9.5) years old at first presentation. Kidney biopsy was performed in 73 cases (54.1%). Kidney pathology showed mild lesions in 41 cases (56.2%), thin basement membrane disease (TBMD) in 24 cases (32.9%), typical pathological features of Alport syndrome in 5 cases (6.8%), and other manifestations in 3 cases (4.1%). The positive group comprised 52 individuals, whereas the negative group consisted of 83 individuals. The positive group demonstrated a higher susceptibility in proteinuria and gene variation, while the negative group exhibited a greater rate of hematuria remission ( χ2=5.00, 5.27, 8.52, all P<0.05). Whole exome sequencing was performed in 80 individuals and 18 individuals (22.5%) had a pathogenic or likely pathogenic variant in COL4A3-5. COL4A5 was the most common gene afected, accounting for 11 cases. The 135 individuals were followed up for 4.2 (2.9, 5.1) years, of which 31 cases (22.9%) had complete hematuria remission at 2.1 (1.4, 2.7) years. Up to March 2024, there were also 7 individuals (5.2%) with varying degrees of proteinuria, and 3 individuals (2.2%) with proteinuria progressed to chronic kidney insufficiency. Conclusions:The most common kidney pathological types in children with persistent asymptomatic microscopic hematuria are minor lesions and TBMD. Children with microscopic hematuria whose first-degree relatives have a family history of hematuria are more likely to have proteinuria and gene variants. COL4A3-5 genetic screening could be considered a priority in these children.

Objective:To evaluate the value of ultrasound radiomics combined with machine learning for early diagnosis of seronegative Hashimoto’s thyroiditis (SN-HT) .Methods:This retrospective study included 164 patients from Liaoning Provincial People’s Hospital , Lixin County People’s Hospital, Linghai Dalinghe Hospital, Fengcheng Phoenix Hospital, who underwent thyroidectomy for solitary nodules with normal thyroid function between Nov. 2016 and Jan. 2024. Postoperative pathology confirmed Hashimoto’s thyroiditis (HT) in some cases, who were further categorized into antibody-positive and antibody-negative groups based on serum antibody status. Patients without Hashimoto’s thyroiditis served as the control group. A total of 298 ultrasound images were analyzed. Radiomics features were extracted from hypoechoic non-nodular areas within 0.5 cm surrounding the tumor. Two senior pathologists and two senior ultrasound physicians independently assessed lymphocytic infiltration, eosinophilic changes of follicular epithelium, and the proportion of hypoechoic areas in pathology and ultrasound images, respectively. A machine learning model, CCH-NET, was developed using linear regression and t-distributed stochastic neighbor embedding (t-SNE) techniques. The dataset was divided into a training set (80%) and a validation set (20%) to compare the diagnostic accuracy of CCH-NET with that of senior ultrasound physicians. Results:In internal validation, CCH-NET achieved a diagnostic accuracy of 88.89% for both antibody-positive and antibody-negative groups, significantly higher than the 66.67% accuracy of senior ultrasound physicians ( P<0.01). In external validation, CCH-NET achieved 75.00% and 66.67% accuracy for the two groups, compared to 50.00% by senior ultrasound physicians. For the control group, both methods achieved 93.33% accuracy. The AUC of CCH-NET was 0.848, outperforming senior ultrasound physicians (0.681) ,demonstrating superior diagnostic performance. Conclusion:The radiomics-based CCH-NET model, using non-nodular hypoechoic areas as a specific indicator, can accurately identify early SN-HT in euthyroid patients. It significantly outperforms senior ultrasound physicians, improving diagnostic accuracy and reducing missed diagnoses.
