Objective: To investigate the correlation of emotional and behavioral problems with sleep problems in children with cerebral palsy, so as to provide reference for intervention of emotional and behavioral problems in children. Methods: A cross sectional survey was conducted, and 402 children aged 6-18 with cerebral palsy who were adopted by social welfare institutions in Guangzhou City from January 2023 to January 2024 were selected to investigate their full time nurses. The Parents Strengths and Difficulties Questionnaire (SDQ) was used to assess the emotional and behavioral problems of children with cerebral palsy, and the Children s Sleep Habits Questionnaire (CSHQ) was used to assess sleep problems. Multiple linear regression analysis was used to analyze the correlation between the sleep problem of children with cerebral palsy and the emotional and behavioral problems. Results: The prevalence of emotional and behavioral difficulties among children with cerebral palsy was 15.7%. The median sleep problem score of children with emotional and behavioral problems [37.0(36.0, 41.0)] was significantly higher than that of children without emotional and behavioral [35.0(34.0, 36.0)] ( Z =-5.74, P <0.01). The results of multiple linear regression analysis showed that after adjusting covariables such as age, gender, cerebral palsy classification, language retardation, visual impairment and epilepsy, the total sleep problem score of children with cerebral palsy was positively correlated with the total difficulty score ( β= 0.28, 95%CI =0.17-0.34, P <0.05). Conclusions Sleep problems in children with cerebral palsy are associated with emotional and behavioral difficulties. Understanding of the management of sleep problems in children with cerebral palsy should be enhanced to reduce the incidence of emotional and behavioral problems in children with cerebral palsy.

AIM:To analyze differential proteins associated with the pathogenesis of dry eye(DE)using bioinformatics methods, in order to reveal their potential molecular mechanisms.METHODS: Articles published in PubMed and EMBASE databases from the inception of the database to August 31, 2023, that used proteomic methods to detect protein expression in clinical samples of dry eye were searched. Differential proteins were selected and further analyzed using the STRING database and Cytoscape software for hub gene screening and module analysis. Protein-protein interaction(PPI)analysis, gene ontology(GO)functional annotation, and Kyoto encyclopedia of genes and genomes(KEGG)pathway enrichment analysis were performed.RESULTS: A total of 21 articles were included, identifying 74 differentially expressed proteins. The most frequently occurring differential proteins were calgranulin A(SA1008), lipocalin-1(LCN1), lysozyme C(LYZ), mammaglobin-B(SCGB2A1), proline-rich protein 4(PRR4), transferrin(TF), and calgranulinB(S100A9). The top 10 hub genes were serum albumin(ALB), tumor necrosis factor(TNF), interleukin 6(IL6), IL1B, IL8, matrix metalloproteinase 9(MMP9), alpha-1-antitrypsin(SERPINA1), IL10, complement component 3(C3), and lactotransferrin(LTF). Module analysis suggested MMP9 and PRR4 as seed genes. KEGG analysis showed that differential proteins were mainly enriched in the IL17 signaling pathway(61.9%).CONCLUSION: The results reveal potential molecular targets and pathways for DE and confirm the association between the pathogenesis of DE and inflammation. Further in-depth research is needed to confirm the significance of these biomarkers in clinical practice.

The study aims to investigate the impacts of prolyl oligopeptidase (POP) on the replication of foot-and-mouth disease virus (FMDV) in BHK-21 cells. Firstly, the effects of FMDV replication on POP expression in BHK-21 cells were analyzed by Western blotting and Real-time reverse transcription polymerase chain reaction (RT-qPCR). Secondly, a eukaryotic expression plasmid for POP was constructed, and the effects of POP overexpression on the replication of two different serotypes of FMDV were assessed by Western blotting, RT-qPCR, and virus titer assays. Thirdly, specific small interfering RNAs (siRNAs) targeting POP were synthesized, and their efficiency in interfering with endogenous POP expression was identified by RT-qPCR. The impacts of downregulating endogenous POP expression on FMDV replication were further evaluated by Western blotting, RT-qPCR, and virus titer assays. The results indicated that FMDV infection did not significantly affect POP expression in BHK-21 cells. Overexpression of POP dose-dependently enhanced the replication of both FMDV/O and FMDV/A serotypes. Conversely, siRNA-mediated downregulation of endogenous POP expression markedly suppressed FMDV/O replication. This study is the first to demonstrated that the role of the host POP protein in promoting FMDV replication in BHK-21 cells, thereby providing a critical theoretical foundation and potential molecular targets for developing efficient candidate cell strains for foot-and-mouth disease inactivated vaccines.

Abstract In recent years, the prevalence of overweight and obesity among children and adolescents has risen rapidly, posing a serious threat to their physical and mental health. To provide scientific, systematic, and standardized weight management guidance for overweight and obese children and adolescents, the study focuses on the core concept of healthy lifestyle intervention, integrates multidisciplinary expert opinions and research findings,and proposes a comprehensive multidisciplinary intervention framework covering scientific exercise intervention, precise nutrition and diet, optimized sleep management, and standardized psychological support. It calls for the establishment of a multi agent collaborative management mechanism led by the government, implemented by families, fostered by schools, initiated by individuals, optimized by communities, reinforced by healthcare, and coordinated by multiple stakeholders. Emphasizing a child and adolescent centered approach, the consensus advocates for comprehensive, multi level, and personalized guidance strategies to promote the internalization and maintenance of a healthy lifestyle. It serves as a reference and provides recommendations for the effective prevention and control of overweight and obesity, and enhancing the health level of children and adolescents.

Objective:To explore the clinical characteristics and genetic basis for a child with global developmental delay and autism.Methods:A child who had presented at West China Second University Hospital of Sichuan University on April 13, 2021 was selected as the study subject. Clinical manifestations, laboratory examination and result of genetic testing were analyzed.Results:The main symptoms of the child had included cognitive, language and motor delay, autism and epilepsy. Electroencephalogram revealed multiple focal discharges in both waking and sleeping stages, with the remarkable one seen at the sleeping stage. Cranial MRI showed pachygyria and local cortical thickening, Whole exome sequencing (WES) revealed that the child has harbored a heterozygous c. 1589_1595dup (p.Gly533Leufs*143) frameshifting variant in the TBR1 gene (OMIM 604616). Based on the guidelines from the American College of Medical Genetics and Genomics, the variant was predicted to be likely pathogenic (PS2+ PVS1_Supporting+ PM2_Supporting). After treated with levetiracetam and rehabilitation training, the child did not have seizure in the past 5 months, and his motor development has also significantly improved. Conclusion:The c. 1589_1595dup variant of the TBR1 gene probably underlay the disease in this patient.

Objective To evaluate the ability of the ratio of peripheral blood white blood cell(WBC)counts to platelet counts to predict the onset of radiation-induced thymic lymphoma(TL)in a mouse model.Methods Mice were subjected to fractionated total-body irradiation(TBI)to established a TL model before the changes of the WBC-to-platelet ratio during the development and progression of TL were investigated.Four-week-old male C57BL/6J mice were randomized into the normal(non-irradiation)group and radiation exposure group that was subjected to 1.8 Gy TBI once weekly for four consecutive weeks.The survival and TL-incidence of those two groups were compared within 370 days of TBI.Histomorphology and hematoxylin & eosin(H&E)staining of the thymus were used for definite diagnosis of TL while flow cytometry was adopted to detect the frequency changes of T cells in the thymus,bone marrow and spleen.Peripheral blood(PB)cell counts were measured to analyze the changes of peripheral hemogram during TL pathogenesis.Results No mice in the normal group were diagnosed with TL while 83％of the irradiated mic suffered from TL within 370 days of fractionated TBI(P＜0.0001).Using histopathologic technology,medium-sized tumor cells were observed in the thymus of irradiated mice diagnosed with TL.Cytometric analysis showed decreased frequencies of CD4 mono-positive cells and increased frequencies of CD8 mono-positive cells in the thymus,bone marrow and spleen of mice diagnosed with TL.PB analysis displayed a significant increase in the WBC-to-platelet ratio one week prior to the TL-caused death in the irradiated mice(P＜0.01).Conclusion Elevation of the peripheral blood WBC-to-platelet ratio can help predict the onset of IR-induced TL of mice.

Objective lo contrast the diagnostic efficacies of perineal and transrectal approaches for combined prostate biopsies guided via magnetic resonance imaging(MRI)and ultrasound fusion imaging.Method A retrospective analysis of clinical data from 271 patients subjected to combined prostate biopsies guided by MRI and ultrasound fusion imaging at the first people's hospital of Wuxue city and Wuhan Tongji Hospital from January 2022 to November 2023 was conducted.They were divided into two groups according to the puncture path,132 cases were transrectal and 139 cases were perineal.The differences between the detection rates of prostate cancer(PCa)and clinical significant prostate cancer(csPCa)across different prostate imaging reporting and data system(PI-RADS)scores and lesion localizations within the two puncture paths were compared.Results The detection rates of PCa in the perineal and transrectal puncture groups(68.3％vs.59.8％,P=0.145)and csPCa(64.7％vs.55.3％,P=0.112)did not exhibit statistically significant differences.However,the perineal puncture group experienced fewer complications.For patients with a PI-RADS score of 4,both PCa(77.2％vs.56.1％,P=0.027)and csPCa(71.9％vs.48.8％,P=0.02)detection rates were higher via the perineal combined biopsy),compared to the transrectal path.Additionally,for apical(PCa:84.3％vs.48.7％,P=0.001;csPCa:81.8％vs.48.7％,P=0.004)and anterior(PCa:77.1％vs.46.5％,P=0.006;csPCa:68.6％vs.44.2％,P=0.031)prostate lesions,the detection rates via the perineal combined biopsy were considerably higher than those of the transrectal path.Conclusion For patients carrying a PI-RADS score of 4 or with prostate lesions situated at the apical or anterior section,the perineal approach for biopsy sampling emerges as the most appropriate method.

Uremic pruritus (UP) is a common complication in patients with end-stage renal disease, which seriously reduces the quality of life of patients. Compared with the internal treatment of TCM, the external treatment of TCM for UP is simpler and more effective, and can avoid the first pass effect caused by oral drugs and may cause liver and kidney damage. The treatment methods mainly include external washing of TCM, medicated bath, fumigation, wet compress, enema, scraping, acupuncture, auricular point sticking, acupoint application, acupoint iontophoresis, autologous blood acupoint injection and so on. At present, most studies are based on the conventional treatment of Western medicine, and the addition of external treatment of TCM can improve the efficacy, and has certain advantages in improving itching symptoms, inflammatory indicators, sleep quality, anxiety and depression. Some studies have selected parathyroid hormone, blood phosphorus, CRP, IL-6, histamine, SCr, BUN, β2-microglobulin and other indicators to evaluate the efficacy. The results suggest that external treatment of TCM can improve the micro-inflammatory state of patients and protect renal function, but further mechanism research is needed. The existing research has the following problems: the clinical efficacy evaluation scale is not uniform, and it is difficult to compare and summarize horizontally; the relief of pruritus symptoms is based on the scale evaluation, which is subjective; the course of treatment is short, and the long-term efficacy and safety can not be evaluated; some studies do not specify the patients' syndrome type, which is difficult to reflect the advantages of TCM syndrome differentiation and treatment, and needed to be improved in the future.
