Objective To investigate the antibody levels against measles, rubella, and mumps in infants aged 0-8 months in Shanghai, and construct a decay trend model, and to provide evidence for formulating prevention and control strategies. Methods Serum samples were collected from infants aged 0 - 8 months at a children's medical center in Shanghai. Enzyme-linked immunosorbent assay (ELISA) was used to measure the IgG antibody levels against measles, rubella, and mumps. The antibody positive rates and antibody geometric mean concentration (GMC) in different age groups were analyzed. Results A total of 922 serum samples were collected. The GMC and positive rates for measles, rubella, and mumps antibodies were 2.11 (127.35 IU·L^-1) and 39.70%; 0.89 (7.89 IU·mL^-1) and 28.85%; and 1.89 (77.80 U·mL^-1) and 41.43%, respectively. There were statistically significant differences in antibody levels and positive rates across different age groups. With the highest levels observed at 0 months, a rapid decline began at 3 months, reaching the lowest levels by 7 months. After the first dose of the MMR vaccine at 8 months, antibody levels increased. A negative correlation was observed between age and GMC for measles, rubella, and mumps antibodies, showing a linear decay trend. The models were as follows: Ŷmeasles = −0.151X + 2.602 (R²=0.91，P＜0.001); Ŷrubella = −0.126X + 1.319(R²=0.98，P＜0.001); Ŷmumps = −0.122X + 2.327 (R²=0.94，P＜0.001). Conclusion The antibody levels for measles, rubella, and mumps in infants decline linearly with increasing age in months. The antibody levels in infants before 8 months of age primarily depend on maternal antibodies. It is recommended that MMR vaccination be promoted for women of childbearing age to enhance early passive immunity protection in infants.

Objective: To explore the current status and influencing factors of eating behaviors in adolescents, so as to provide a theoretical foundation for health promotion education among adolescents. Methods: Based on the database from Survey of Chinese Family Health Index (2021), by a random number table method, 1 065 teenagers were selected from the provincial capitals of 22 provinces and 5 autonomous regions in China, as well as 4 municipalities directly under the central government. A general characteristic questionnaire, Patient Health Questionnaire-9 (PHQ-9), Short Form of the Family Health Scale (FHS-SF), 10-item Short Version of the Big Five Personality(BFP-10), Content-based Media Exposure Scale (CM-E) and Sakata Eating Behavior Scale Short Form(EBS-SF) were used to collect information. Multivariate stepwise linear regression analysis was employed to identify and analyze related factors of eating behaviors among adolescents. Receiver operating characteristic was used to validate the predictive ability of the EBS-SF score for overweight and obesity among adolescents. Results: The average scores of BFI-10,C-ME, FHS-SF, PHQ-9 and EBS-SF were (33.08±4.64)(19.20±4.55)(38.48±6.65)(6.09±5.63)(16.75±4.36), respectively. Multivariate linear regression showed that family type (other types), agreeableness, conscientiousness, family health and depression were the main related factors of EBS-SF scores among adolescents( B =2.61,-0.42,0.20,-0.11,0.23, P <0.05).The analysis of receiver operating characteristic curve showed that the EBS-SF scores had a good ability in predicting obesity among male adolescents ( AUC= 0.73, P <0.01). Conclusions Family type, big five personality, family health,depression are the related factors of eating behaviors among adolescents. EBS-SF scores are predictive of obesity in adolescents, which would provide a new perspective for promoting healthy eating habits among adolescents.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Objective:To explore the relationship between early fecal calprotectin (FC) level and the long-term efficacy of infliximab (IFX) in the treatment of Crohn′s disease (CD) and predictive the value.Methods:From January 2018 to December 2023, at the First Affiliated Hospital with Nanjing Medical University, the clinical data of patients with moderate-to-severe CD who received IFX as first-line therapy were retrospectively collected. The main outcomes were clinical and endoscopic remission at week 52 after IFX treatment, and the secondary outcome was clinical response at week 14 after IFX treatment. The predictive value of FC levels at week 0 (at baseline when first administered) and week 14 of treatment was evaluated for the clinical and endoscopic remission at week 52 after IFX treatment. Multivariate logistic regression was performed to investigate the factors predicting endoscopic remission. The optimal cutoff value was calculated, model was established, the data was divided into training set and validation set at a ratio of 7∶3 using the random number table method and the corresponding column chart was drawn. Receiver operating characteristic curve (ROC) and calibration curve were used to evaluate the discrimination and calibration of the model, respectively. Mann-Whitney U test was used for statistical comparison. Results:A total of 165 patients with CD were enrolled, of whom 150 cases (90.9%) achieved clinical response after induction therapy, and 15 cases (9.1%) were primary non-response. Among the 150 patients with clinical response, 112 cases (74.7%) achieved clinical remission at week 52 after treatment, while 38 cases (25.3%) did not achieve clinical remission. Endoscopic evaluation was performed at week 52 after treatment in 139 patients, of whom 54 cases (38.8%) achieved endoscopic remission and 85 cases (61.2%) did not. At week 14 of treatment, there was no statistically significant difference in FC level between the patients achieved and did not achieve clinical response (263.24 (93.96, 675.28) μg/g vs. 556.35 (245.77, 953.56) μg/g, P>0.05). At week 52 after treatment, the FC level of patients who achieved clinical remission was lower than that of patients did not achieve(103.20(44.11, 456.57) μg/g vs. 531.26(222.06, 998.40) μg/g) and the decreased value of FC at week 52 and week 0 after treatment of patients achieved clinical remission was more than that of patients did not achieve clinical remission (443.34 (82.25, 788.95) μg/g vs. 269.91 (-79.20, 522.54) μg/g), and the differences were statistically significant ( U=1 078.00, 2 677.00; P<0.001, =0.018). At week 52 after treatment, the FC level of patients achieved endoscopic remission was lower than that of patients did not achieve endoscopic remission (52.80(31.93, 83.47) μg/g vs. 506.18(217.44, 778.02) μg/g), and the decreased value of FC at week 52 and week 0 after treatment of patients achieved endoscopic remission was more than that of patients did not achieve endoscopic remission (428.85(140.20, 863.60) μg/g vs. 309.61(-62.37, 683.82) μg/g), and the differences were statistically significant ( U=500.00, 2 812.00; P<0.001, =0.025). The FC level at week 14 of treatment could predict the clinical and endoscopic remission at week 52 after treatment (area under the curve (AUC) =0.663, 0.773; 95% confidence interval (95% CI): 0.566 to 0.760, 0.694 to 0.852; P=0.006, <0.001). The optimal cutoff value of FC at week 14 of treatment for predicting endoscopic remission at week 52 after treatment was 246.13 μg/g, with a sensitivity of 0.741 and a specificity of 0.671. The results of multivariate logistic regression analysis revealed that FC ≤ 246.13 μg/g at week 14 of treatment ( OR=4.576, 95% CI: 2.021 to 10.363, P<0.001), baseline albumin ( OR=1.093, 95% CI: 1.006 to 1.188, P=0.035), and baseline platelet-to-lymphocyte ratio (PLR) ( OR=0.995, 95% CI: 0.990 to 1.000, P=0.046) were independent influencing factors of endoscopic remission at week 52 after treatment. A predictive model for endoscopic remission at week 52 after IFX treatment was established based on FC ≤ 246.13 μg/g at week 14 of treatment, baseline albumin and PLR. The results of ROC analysis showed that this model had good discriminative ability, with an AUC of 0.780 (95% CI: 0.700 to 0.878) in the validation set, with a sensitivity of 0.812 and a specificity of 0.760. The results of calibration curve analysis demonstrated that the average absolute error of the prediction model in the validation set was 0.038, and the consistency between the predicted probability and the actual probability was good. Conclusion:FC ≤ 246.13 g/g at week 14 of IFX treatment has good predictive value for endoscopic remission at week 52 after treatment in CD patients.

ObjectiveWith the development of society and the increasing demand for pregnancy at an advanced age， diminished ovarian reserve （DOR） has attracted wider attention. This disease affects the normal menstruation of women and poses a threat to their mental health. Current research on DOR is still in the initial stage， and advancing research progress in DOR necessitates the construction of effective and clinically relevant animal models. Building on existing literature and integrating the diagnosis criteria of DOR in traditional Chinese medicine （TCM） and Western medicine， this study summarized， analyzed， and evaluated existing models， providing a reference for optimizing DOR animal models. MethodsA retrospective analysis of literature on DOR-related animal models was conducted， and the diagnostic criteria of DOR in TCM and Western medicine were sorted out. By means of evaluation methods of animal models， the clinical relevance of each model to TCM and Western medicine was assessed. ResultsDOR animal models included those based on natural factors， iatrogenic factors， immune factors， metabolic factors， and environmental factors. Among them， the model based on iatrogenic factors， especially models induced by Tripterygium wilfordii preparations， cyclophosphamide， and cisplatin， had a high degree of relevance to both Western medical diseases and TCM syndromes and was confirmed as the optimal modeling method for studying DOR at present. ConclusionThe existing DOR modeling methods mostly have a high degree of clinical relevance to Western medical diseases， while the number of DOR animal models with clear TCM syndromes is very limited. TCM plays an indispensable role in exploring DOR treatment methods. Therefore， the development of DOR animal models related to TCM syndromes should be strengthened， further exploring the potential of TCM and providing strong theoretical support for the application of TCM in DOR treatment.

OBJECTIVE To investigate the clinical efficacy of integrating pharmacists into family health teams （FHTs） for long-term medication therapeutical management （MTM） in stroke patients， and empirically evaluate the service model. METHODS A pharmacist team， jointly established by clinical and community pharmacists from the Affiliated Suzhou Hospital of Nanjing Medical University （hereinafter referred to as “our hospital”）， developed a pharmacist-supported MTM model integrated into FHTs. Using a prospective randomized controlled design， 170 stroke patients discharged from our hospital （July 2022-December 2023） and enrolled in FHTs at Suzhou Runda Community Hospital were randomly divided into trial group （88 cases） and control group （82 cases） according to random number table. The control group received routine FHTs care （without pharmacist involvement in the team collaboration）， while the trial group xhz8405@126.com received 12-month MTM services supported by pharmacists via an information platform. These services specifically included innovative interventions such as personalized medication regimen optimization based on the MTM framework， dynamic medication adherence management， medication safety monitoring， a home medication assessment system， and distinctive service offerings. Outcomes of the 2 grousp were compared before and after intervention， involving medication adherence （adherence rate， adherence score）， compliance rates for stroke recurrence risk factors [blood pressure， low-density lipoprotein cholesterol （LDL-C）]， and incidence of adverse drug reactions （ADR）. RESULTS After 12 months， the trial group exhibited significantly higher medication adherence rates， improved adherence scores， higher compliance rates for blood pressure and LDL-C targets compared to the control group （P＜0.05）. The incidence of ADR in the trial group （4.55%） was significantly lower than that in the control group （8.11%）， though the difference was not statistically significant （P＞ 0.05）. CONCLUSIONS Pharmacist involvement in FHTs to deliver MTM services significantly enhances medication adherence and optimizes risk factor for stroke recurrence， offering practical evidence for advancing pharmaceutical care in chronic disease management under the family doctor system.

Objective:To analyze the prevalence of chronic kidney disease (CKD) and influencing factors of adults in Hebei Province, and provide scientific evidence for the development of comprehensive CKD prevention and control strategies.Methods:In China Adult Chronic Disease and Nutrition Surveillance in Hebei in 2018, a total of 7 562 permanent residents aged ≥18 years were selected by multi-stage stratified cluster random sampling from 13 surveillance points in Hebei for questionnaire survey, medical examination and laboratory test.Results:A total of 1 067 CKD patients were detected in the adults aged ≥18 years in this survey, with a weighted prevalence rate of 12.10%. The results of multivariate analysis showed that the daily total static behavior time ( OR=1.07, 95% CI: 1.04-1.09), living in rural area ( OR=1.50, 95% CI: 1.14-1.97), coal use ( OR=1.37, 95% CI: 1.16-1.61), coal gas/liquefied gas/natural gas/biogas use ( OR=2.92, 95% CI: 2.40-3.54) and solar energy/electricity use ( OR=1.75, 95% CI: 1.36-2.25), insufficient fruit intake ( OR=1.39, 95% CI: 1.06-1.83), insufficient physical activity ( OR=1.35, 95% CI: 1.11-1.64), suffering from hypertension ( OR=1.80, 95% CI: 1.44-2.24) and suffering from diabetes ( OR=1.77, 95% CI: 1.27-2.45) were risk factors for CKD in adults in Hebei. High education level ( OR=0.41, 95% CI: 0.19-0.91), excessive drinking ( OR=0.53, 95% CI: 0.28-0.99), central obesity ( OR=0.75, 95% CI: 0.58-0.97), history of allergic diseases ( OR=0.44, 95% CI: 0.27-0.72) were protective factors for CKD. Conclusions:The prevalence of CKD in adults in Hebei was relatively high, especially in those who had too long average daily static behavior, lived in rural area, used coal, gas/liquefied gas/natural gas/biogas, solar energy/electricity, had inadequate intake of fruits, lacked physical activity and suffered from hypertension and diabetes. It is necessary to pay attention to the early prevention and treatment of CKD, strengthen the health education about healthy lifestyle and improve the management of patients with chronic disease, such as hypertension and diabetes, to further reduce the risk for CKD.

Objective:To investigate the impact of immunosuppressive therapy on the severity of SARS-CoV-2 infection and cytokine levels in pediatric patients with kidney diseases.Methods:A retrospective analysis was conducted on the clinical data of 40 hospitalized pediatric patients who were diagnosed with SARS-CoV-2 infection at the 900th Hospital of PLA Joint Logistic Support Force from December 2022 to February 2023. Based on their immunosuppressive status prior to SARS-CoV-2 infection, these patients were categorized into immunosuppressive group and non-immunosuppressive group. Independent sample t-tests, Mann-Whitney U tests, and χ2 test were employed to compare the clinical baseline characteristics and laboratory data, the severity of SARS-CoV-2 infection, and the levels of cytokines between the 2 groups. Results:Among the 40 patients, 11 were in the immunosuppressive group (aged 13 (8, 14) years, 9 males and 2 females) and 29 in the non-immunosuppressive group (aged 2 (1, 4) years, 15 males and 14 females). In the immunosuppressive group, 2 were asymptomatic cases, 8 were mild cases, and 1 was moderate case, and there was no severe or critical cases. In the non-immunosuppressive group, 8 were mild cases, 5 were moderate, 15 were severe cases, 1 was critical case, and no asymptomatic cases. The underlying diseases in the immunosuppressive group included nephrotic syndrome (6 cases), IgA vasculitis nephritis (2 cases), lupus nephritis (1 case), post-renal transplantation (1 case), and renal failure (1 case), with a mean total immunosuppression score (TIS) of (3.6±1.4) points. In the non-immunosuppressive group, 2 patients had a history of epilepsy, and the remaining 27 cases had no underlying conditions, all with TIS scores of 0. Compared to the children in the non-immunosuppressive group, those in the immunosuppressive group were more likely to exhibit asymptomatic or mild infection, with lower risks of severe disease, cytokine storm, fever, and cough, but a higher risk of fatigue ( OR=1.22, 2.66, 0.48, 0.12, 0.12, 0.13, 1.22; 95% CI 0.93-1.62, 0.99-7.15, 0.33-0.70, 0.03-0.57, 0.03-0.57, 0.03-0.65, 0.93-1.62; all P<0.05). The levels of cytokine IL-6, interferon-α and interferon-γ in the immunosuppressive group were all lower than those in the non-immunosuppressive group ( Z=2.23, 2.51, 2.92, respectively; all P<0.05). Conclusion:Pediatric patients with kidney diseases receiving appropriate immunosuppressive therapy may mitigate the severity of SARS-CoV-2 infection by suppressing the expression of cytokines.
