ObjectiveTo establish an educational intervention framework of electronic picture books for children with autism spectrum disorder (ASD) based on Creative Problem Solving (CPS) model, and observe the effect on social function. MethodsElectronic picture books were designed using CPS model, including the program of reading, interactive animation design and associated artistic activities. From March to June, 2023, 24 children with mild to moderate ASD were recruited from Maanshan Institute of Special Education, and randomly assigned into experimental group 1 (CPS-based cognitive picture book interventions, n = 8), experimental group 2 (CPS-based social picture book interventions, n = 8) and control group (Bloom's Taxonomy-based picture book interventions, n = 8), and received the interventions for four weeks, with a total of twelve times. They were assessed with speech, social, perceptual and health behavior using Autism Treatment Evaluation Checklist (ATEC) before and after treatment, and the differences were calculated. ResultsThere was a significant difference among the groups in the social and perceptual scores differences (F > 4.344, P < 0.05) and a near-significant difference in the health behaviour score difference (F = 2.921, P = 0.076). Post Hoc test showed that the differences in social scores were higher in both experimental groups than in the control group (P < 0.05); the difference in perceptual scores was significantly higher in experimental group 1 than in experimental group 2 (P < 0.01), but there was no significant difference with the control group (P > 0.05); the difference in health behavior scores was higher in experimental group 2 than in the control (P < 0.05), and the difference in experimental group 1 was slightly higher than in the control group (P = 0.072). ConclusionElectronic picture book interventions based on the CPS model may be more effective in enhancing social, perceptual and health behavior in children with ASD, but there may be differences among models.

Objective: To investigate the environmental contamination of norovirus in nurseries and primary/secondary schools, so as to provide a scientific basis for effective prevention and control measures. Methods: A total of 483 external environmental samples were collected from 34 cluster outbreaks of norovirus gastroenteritis in kindergartens and primary/secondary schools in Linhai City from 2021 to 2024. Pathogen detection was conducted using a rapid nucleic acid extraction kit and realtime fluorescence RT-PCR, and the results were analyzed using the χ2 test or Fishers exact test. Results: Among the collected external environmental samples, the total positive rate of surface contamination was 13.66%. The positive rates in kindergartens and primary/secondary schools were 12.20% and 15.82%, respectively. In kindergartens, the five surfaces with the highest detection rates were desks/chairs (23.33%), toilet stool troughs (20.69%), urinal troughs (12.00%), washbasins/sinks (11.11%), and toilet mops (9.38%). In primary/secondary schools, the top five were toilet stool troughs (38.30%), urinal troughs (23.53%), toilet door handles (13.04%), toilet mops (12.50%), and drinking cups (11.11%). The difference in positive detection rates among different external environments in primary/secondary schools was statistically significant (Fishers exact probability test, P<0.01). The positive detection rate in sanitary toilets was higher than that in classroom environments (χ2=17.38), while the positive detection rate in classroom environments of kindergartens was higher than that in primary/secondary schools (χ2=5.42)(P<0.05). Conclusions Norovirus exhibits a high contamination rate in nurseries and schools, particularly in restroom areas. Strengthening sanitation and disinfection in highrisk environments, and improving hygiene awareness among children and staff, are essential for the effective prevent and control of norovirus.

Oxidative stress due to aberrant metabolism is considered as a crucial contributor to diabetes and its complications. Hyperglycemia and hyperlipemia boost excessive reactive oxygen species generation by elevated mitochondrial respiration, increased nicotinamide adenine dinucleotide phosphate oxidase activity, and enhanced pro-oxidative processes, including protein kinase C pathways, hexosamine, polyol, and advanced glycation endproducts, which exacerbate oxidative stress. Oxidative stress plays a significant role in the onset of diabetes and its associated complications by impairing insulin production, increasing insulin resistance, maintaining hyperglycemic memory, and inducing systemic inflammation. A more profound comprehension of the molecular processes that link oxidative stress to diabetes is crucial to new preventive and therapeutic strategies. Therefore, this review discusses the mechanisms underlying how oxidative stress contributes to diabetes mellitus and its complications. We also summarize the current approaches for prevention and treatment by targeting the oxidative stress pathways in diabetes.

Objective To investigate the relationship between different interleukins (ILs) and gynecological tumors, including cervical cancer, endometrial cancer, and uterine leiomyoma using two-sample Mendelian randomization (MR) analysis. Methods IL and gynecological tumor data were obtained from European populations by using the IEU OpenGWAS open database. Two-sample MR analysis was applied, different interleukins were used as exposure factors, significant SNP in GWAS data were selected as instrumental variables, and the instrumental variables were independent of each other. The risk of three kinds of gynecological tumors was analyzed separately to explore the causal relationship between ILs predicted by genes and outcome indicators. The TwoSampleMR package in R language (4.3.1) software was used for statistical analysis. MR analysis was performed using inverse variance weighted, MR Egger regression, weighted median, simple mode, and weighted mode methods. Results IL-18 receptor 1 (P=0.039) and IL-24 (P=0.025) were negatively correlated with the risk of cervical cancer. IL-4 (P=0.040), IL-21 (P=0.026), and IL-37 (P=0.027) were positively correlated with the risk of endometrial cancer. IL-15 receptor subunit alpha (P=0.005) was negatively correlated with the risk of endometrial cancer. IL-17A (P=0.005) and IL-37 (P=0.018) were negatively correlated with the risk of uterine leiomyoma. IL-21 (P=0.035) was positively correlated with the risk of uterine leiomyoma. Conclusion Genetically predicted IL-4, IL-15Rα, IL-17A, IL-18R1, IL-21, IL-24, and IL-37 are causally associated with the risk of three gynecological tumors. Further exploration of the molecular mechanism of ILs in gynecological tumors may provide potential therapeutic targets for the treatment of gynecological tumors.

Objective:To detect pathogenic mutation in a Chinese family affected with isolated bilateral microtia.Methods:During 2022 June to December, one Chinese Han family with non-syndromic bilateral microtia was recruited at the First Hospital of Shanxi Medical University. The clinical data and peripheral blood samples were collected from the family members. Whole genome sequencing (WGS) was performed in the proband to screen all candidate variants. Quantitative PCR was applied to identify the candidate copy number variation (CNV) among the proband, the unaffected wife and the affected son to demonstrate the association between candidate variant and phenotype.Results:The patients in the family had non-syndromic bilateral concha-type microtia. WGS detected the duplication in the intergenic region of HMX1 and CPZ gene in the proband, which involved the evolutionarily conserved region (ECR). Both the proband and his affected son carried the CNV, while his unaffected wife did not have this variation.Conclusion:Duplications involving the long range HMX1 enhancer ECR are associated with the bilateral concha-type microtia in this family.

Two pediatric heart failure patients were treated with pulmonary artery banding(PAB)at Fuwai Hospital,from December 2021 to January 2022.In the first case,an 8-month-old patient presented with left ventricular non-compaction cardiomyopathy(LVNC),left ventricular systolic dysfunction,ventricular septal defect,and atrial septal defect.The second case was a 4-month-old patient with LVNC,left ventricular systolic dysfunction,and coarctation of the aorta.After PAB,the left ventricular function and shape of both patients were significantly improved,without serious surgery-related complications.In these individual cases of pediatric heart failure,pulmonary artery banding exhibited a more satisfactory efficacy and safety compared to pharmacological treatment,especially for those with unsatisfactory medication results.Future clinical data are needed to promote the rational and broader application of this therapeutic option for indicated patients.

Objective To explore the relationships of MRI manifestations of pericruciate ligament fat pad(PCFP)with the severity of knee osteoarthritis(KOA).Methods Fifty patients with MRI diagnosed KOA(KOA group)and 30 healthy subjects(control group)were retrospectively included.Signal intensity changes of PCFP,infrapatellar fat pad(IPFP),quadriceps fat pad(QFP)and prefemoral fat pad(PFP)were observed,and the maximum cross-sectional areas were obtained.The severity of KOA was assessed,including knee cartilage injury,anterior cruciate ligament tear,bone marrow lesion(BML),meniscal injuries and Park classification.MRI parameters of fat pad were compared between groups,and correlations of PCFP MRI parameter and other fat pad MRI parameters with the severity of KOA were analyzed.Results Signal change grade of IPFP and PCFP were significant different between groups(both P＜0.05),and the maximum cross-sectional area of IPFP and the thickness of PFP patellofemoral in KOA group were smaller than,while the maximum cross-sectional area of PCFP in KOA group was larger than that in control group(all P＜0.05).The signal change grade of PCFP was positively related to signal change grade of IPFP(rs=0.557)but negatively related to PFP interpatellofemoral thickness(rs=-0.651).The maximum cross-sectional area of PCFP was positively related to the maximum cross-sectional area of IPFP,PFP and QFP,also to the QFP occupancy effect(n=0.314 to 0.368).The signal change grade of PCFP was positively related to the cartilage injuries of knee compartments(medial and lateral patellofemoral joints,the femoral medial and lateral,the tibial medial and lateral)(rs=0.502 to 0.735),and the maximum cross-sectional area of PCFP was related to the lateral femoral cartilage injury(rs=0.305).In addition,the signal change grade of PCFP was positively related to tear of anterior cruciate ligament,BML,medial meniscus tears,lateral meniscus tears,medial meniscus extrusion,exudative synovitis and Park grading(rs=0.425 to 0.789),while the maximum cross-sectional area of PCFP was positively related to BML(rs=0.313).Conclusion MRI signal changes of PCFP could indicate KOA,and the grade of signal changes was correlated with the severity of KOA.

Objective:To explore the clinical warning value of ischemic modified albumin (IMA) and IMA to human serum albumin (HSA) ratio (IMAR) in the development of pre-eclampsia (PE) and its severity.Methods:A total of 156 pregnant women with PE admitted to the Haidian District Maternal and Child Health Hospital of Beijing from April 2022 to March 2023 were collected as the PE group, and 156 healthy pregnant women with the same age and gestational age were matched as the control group. PE pregnant women were further divided into severe PE group (78 cases) and non-severe PE group (78 cases). Severe PE pregnant women were divided into emergency group (42 cases) and non-emergency group (36 cases) according to the disease progression time.All pregnant women were stratified according to their HSA levels (<30 g/L, 30-32 g/L, ≥32 g/L), and the peripheral blood IMA, HSA, and IMAR of pregnant women in different periods and subgroups were compared, and also the difference of IMA levels in umbilical artery blood. Bivariate correlation analysis was used to explore the correlation between severe PE and IMA or IMAR, and receiver operating characteristic (ROC) curves was used to analyze the diagnostic value of IMA, HSA, and IMAR for PE and severe PE.Results:(1) The IMA level and IMAR in peripheral serum of pregnant women in the PE group at diagnosis, and the IMA level in umbilical artery blood at delivery, and peripheral serum at 2 days after delivery were higher than those in the control group. The HSA level in peripheral serum was lower than that in the control group at diagnosis, and the differences were statistically significant (all P<0.001). (2) The IMA level and IMAR in the peripheral serum of pregnant women with severe PE were higher than those in the non-severe PE group at diagnosis, while the HSA level were lower than those in the non-severe PE group. The differences were statistically significant (all P<0.05). At diagnosis, the IMA level and IMAR in peripheral serum of pregnant women in the emergency group were higher than those in the non-emergency group, while the HSA level was lower than that in the non-emergency group. The differences were statistically significant (all P<0.05). When diagnosed, the peripheral serum IMA levels of pregnant women in the PE group were compared between subgroups with HSA<30 g/L, 30-32 g/L, ≥32 g/L, and there was no statistically significant difference ( F=0.366, P=0.694). However, the IMAR was compared between the three subgroups, and the difference was statistically significant ( F=28.544, P<0.001), which increased with the decrease of HSA levels. In the subgroup with HSA≥32 g/L, the peripheral serum IMA level and IMAR of pregnant women in the PE group were higher than those in the control group at diagnosis, and the differences were statistically significant (all P<0.001). (3) The severe PE manifestations positively correlated with peripheral serum IMAR at diagnosis include systolic blood pressure ( r=0.279), mean arterial pressure ( r=0.212), and urinary protein quantification ( r=0.277), while the severe PE manifestations negatively correlated include HSA levels ( r=-0.644) and newborn birth weight ( r=-0.305), all of which were significantly correlated ( P<0.05). (4) The area under curve (AUC) for IMAR diagnosis of PE was 0.875 (95% CI: 0.833-0.916), with the highest diagnostic efficiency at a cutoff value of 2.06, sensitivity of 72.5%, and specificity of 85.1%. The AUC for diagnosing severe PE was 0.871 (95% CI: 0.822-0.919), with the highest diagnostic efficacy at a cutoff value of 2.18, sensitivity of 72.3%, and specificity of 88.3%. The diagnostic efficacy of IMAR for PE and severe PE were higher than those of IMA and HSA levels. Conclusions:The level of IMA and IMAR in pregnant women with PE are higher than those in normal pregnant women. IMA and IMAR are correlated with the severity of PE, with IMAR changes occurring earlier and more significantly. IMAR could be considered as one of the evaluation indicators for the development of PE, or as a more sensitive PE severity warning indicator than HSA.

Objective:To explore the effectiveness of the comprehensive healthcare management model for children with bacterial meningitis after discharge.Methods:This study was a retrospective cohort study that included 268 children with bacterial meningitis who were discharged from the infectious medicine ward of Beijing Children′s Hospital from September 2018 to September 2023. The children were managed with a multidisciplinary collaborative comprehensive healthcare management model after discharge. Outpatient data at 1 month and 6, 12 and 24 months after discharge were collected, including (height, weight, body mass index, nutritional feeding status, hearing and vision screening results, Gesell developmental assessment results and intervention guidance services. The follow-up interval or frequency was dynamically adjusted or increased according to the child′s situation. The paired sample t-test and chi square test were applied to compare the differences in Gesell developmental quotient (DQ) and developmental delay rate between the first and last assessments to preliminarily explore the effectiveness of the comprehensive healthcare management model for children with bacterial meningitis after discharge. Results:All the 268 children completed their first assessment one month after discharge, and 37 children were found to have abnormal physical growth, mainly obesity (28 children), and another 9 children were malnutrition. Nutritional intervention and feeding guidance services were provided to all the 37 children, and as of the last follow-up, 20 children′s physical growth evaluations had turned normal. A total of 188 children completed at least 2 developmental assessments, with an interval of (14.2±9.4) months between the first and last assessments (range: 3.1-49.5 months). The DQ values of in the energy region of adaptability, gross motor skills, fine motor skills, language, and personal social skills at the last assessment were significantly higher than those at the first assessment [(91.93±13.28) vs (80.73±15.96) points, (91.69±12.96) vs (78.31±16.58) points, (89.32±16.11) vs (80.68±15.63) points, (90.10±16.65) vs (82.04±18.43) points, (92.01±14.05) vs (77.82±17.42) points]; moreover, the rates of developmental delay in each energy region were significantly lower than those at the initial assessment (9.6% vs 35.1%, 9.6% vs 42.0%, 18.1% vs 33.0%, 13.3% vs 31.9%, 9.6% vs 42.0%) (all P<0.05). Among the 200 children who completed the hearing screening, 18 were found with hearing abnormalities, and 2 were diagnosed with hearing loss in the Otolaryngology Department. Among 217 children who completed vision screening, 23 had abnormalities, and 5 were diagnosed with ophthalmic abnormalities in Ophthalmology Department (2 with strabismus, 2 with refractive errors, and 1 with optic nerve injury). Two children were found to have autism-like behavior during monitoring, and were referred to a developmental behavior clinic to be diagnosed with autism spectrum disorder and were given early diagnosis and intervention guidance. Conclusion:The comprehensive healthcare management model for children with bacterial meningitis after discharge can integrate clinical and healthcare resources, which is beneficial for improving the prognosis and enhancing the quality of life for children with special health status.
