【Objective】 To clarify the concept of health literacy among children and adolescents with accidental injuries through literature review and analysis. 【Methods】 A systematic search was conducted across multiple databases, including China National Knowledge Infrastructure, Wanfang database, VIP database, China Biomedical literature database, PubMed, CINAHL, and PscyINFO database. The literature was analyzed using Rodgers′ evolutionary concept analysis method. 【Results】 A total of 56 articles were included. The health literacy of children and adolescents with accidental injuries comprised three conceptual attributes:cognition, emotion and behavior. The influencing factors included children′s demographic factors, family and school related factors and social related factors. The result can be beneficial to reduce the occurrence of injury events, save family economic expenditure and alleviate the burden on social medical resources. However, there is currently a lack of specific measurement tools for assessing health literacy in this population, as the existing evaluation items are drawn from general health literacy scales. 【Conclusions】 The concept of health literacy among children and adolescents with accidental injuries is multifaceted and evolving. Future research should focus on exploring the characteristics of health literacy among children and adolescents of different ages and regions from their own perspectives. Additionally, efforts should be made to refine the concept and develop specialized measurement tools to facilitate further studies in this area.

Objective:A dose verification system of two-dimensional semiconductor matrix(SRS MapCHECK)was used to verify the dose of the clinical treatment plan of patients who underwent CyberKnife(CK),which realized rapid verification for individualization of radiotherapy plans of patients through analyzed the γ-passing rates of them.Methods:A total of 253 patients with tumor who received CK clinical treatment in the First Medical Center of Chinese PLA General Hospital from March 2021 to May 2023 were selected.Among of them,121 cases received CK treatment on head,and 30 cases received that on lung,and 102 cases received CK treatment on abdomen and other metastatic tumor.In the MultiPlan treatment plan system,the plan of patient was mapped to the integrated model composed of StereoPHAN model and SRS MapCHECK matrix dose verification system by the means of the plan image center overlap.The dose verification was conducted on the plan of each patient on the basis of ensuring the consistency of the number of beam,direction of beam and the monitor unit.The different γ analysis standards(1%/1 mm,2%/1 mm,3%/1 mm,1%/2 mm,2%/2 mm,3%/2 mm,1%/3 mm,2%/3 mm and 3%/3 mm)were adopted to conduct global analysis of absolute dose for each verification plan,and the threshold(TH)of low dose was set as 10%.Results:The γ passing rates of phantom verification plans of 253 patients were respectively(88.64±5.91)%,(95.43±3.40)%,(97.90±2.06)%,(96.51±2.35)%,(98.15±1.68)%,(99.06±1.12)%,(98.30±1.39)%,(99.09±0.97)%and(99.52±0.63)%under different analysis standards.The γ passing rates of other standards of patients with tumor on different parts were larger than 95%except the analysis result of 1%1 mm standard.The overall analysis result of the deviation of central point dose was(-1.30±2.17)%,among of which the tumor of head,abdominal tumors and other metastatic tumor were about approximately-2%,while that of lung tumors were approximately-3%.The deviation of abdominal and other metastatic tumor was the minimum.The correlation analysis showed that the target volume and the size of the minimum collimator were respectively correlated to the dose deviation of the center.Conclusion:SRS MapCHECK dose verification system can conveniently and quickly realize the individualized verification for the plan of patients who receive CK treatment.

Objective To investigate the effects of AIDS and tuberculosis(TB)co-infection on CD8+T lymphocytes.Methods Serum CD8+T cells and CD4+T cells were analyzed and compared between human immunodeficiency virus(HIV)alone patients(n=200),TB alone patients(n=200),and HIV/TB co-infection patients(n=200).Results CD8+T cells were significantly higher in HIV alone group compared to HIV/TB co-infection group and TB alone group(x2=128.779,P＜0.001).The level of CD8+T lymphocytes in HIV/TB co-infection group and HIV alone group was higher than normal level(ZHIV/TB=8.343,PHIV/TB＜0.001,ZHIV=7.988,PHIV＜0.001).The CD8+T cells in TB alone group decreased significantly compared with normal levels(ZTB=8.682,PTB＜0.001).The levels of CD4+T cells in the three groups of patients were all lower than normal(ZHIV=11.088,PHIV＜0.001,ZTB=5.562,PTB＜0.001,ZHIV/TB=12.077,PHIV/TB＜0.001).The stratified analysis of CD8+T cell levels by CD4+T cell counts,showed that when CD4+T cell count was≤100 cells/μL,the level of CD8+T cells in HIV alone group was higher than that in TB alone group.HIV alone group had higher CD8+T cells than HIV/TB co-infection group,and the level of CD8+T cells in HIV/TB co-infection group was significantly lower than normal(Z0-100=1.604,P0-100=0.109).When CD4+T cells ≥101 cells/μL,HIV/TB co-infection group had higher CD8+T cells than TB alone group.HIV alone group had higher CD8+T cells than TB alone group.When CD4+T cells＞500 cells/μL,CD8+T cell levels were within the normal range in all three groups of patients.Taking the HIV alone group as a reference,with the decrease of CD4+T cell count,the CD8+T cell count decreased more significantly in TB alone group and HIV/TB co-infection group than in HIV alone group(slope was 0.344 and 0.216,respectively,P＜0.001).Conclusions With the decline of CD4+T cells,both HIV/TB co-infection and TB alone are associated with decrease in CD8+T cells,and the decrease in the TB alone group is more prominent.

Purpose: This study aims to evaluate the efficacy and safety of a new combination treatment of vinorelbine and pyrotinib in human epidermal growth factor receptor 2 (HER2)–positive metastatic breast cancer (MBC) and provide higher level evidence for clinical practice. Materials and Methods: This was a prospective, single-arm, phase 2 trial conducted at three institutions in China. Patients with HER2-positive MBC, who had previously been treated with trastuzumab plus a taxane or trastuzumab plus pertuzumab combined with a chemotherapeutic agent, were enrolled between March 2020 and December 2021. All patients received pyrotinib 400 mg orally once daily plus vinorelbine 25 mg/m2 intravenously or 60-80 mg/m2 orally on day 1 and day 8 of 21-day cycle. The primary endpoint was progression-free survival (PFS), and the secondary endpoints included the objective response rate (ORR), disease control rate (DCR), overall survival, and safety. Results: A total of 39 patients were enrolled. All patients had been pretreated with trastuzumab and 23.1% (n=9) of them had accepted trastuzumab plus pertuzumab. The median follow-up time was 16.3 months (95% confidence interval [CI], 5.3 to 27.2), and the median PFS was 6.4 months (95% CI, 4.0 to 8.8). The ORR was 43.6% (95% CI, 27.8% to 60.4%) and the DCR was 84.6% (95% CI, 69.5% to 94.1%). The median PFS of patients with versus without prior pertuzumab treatment was 4.6 and 8.3 months (p=0.017). The most common grade 3/4 adverse events were diarrhea (28.2%), neutrophil count decreased (15.4%), white blood cell count decreased (7.7%), vomiting (5.1%), and anemia (2.6%). Conclusion Pyrotinib plus vinorelbine showed promising efficacy and tolerable toxicity as second-line treatment in patients with HER2-positive MBC.

Rapid serial visual presentation (RSVP) is a type of psychological visual stimulation experimental paradigm that requires participants to identify target stimuli presented continuously in a stream of stimuli composed of numbers, letters, words, images, and so on at the same spatial location, allowing them to discern a large amount of information in a short period of time. The RSVP-based brain-computer interface (BCI) can not only be widely used in scenarios such as assistive interaction and information reading, but also has the advantages of stability and high efficiency, which has become one of the common techniques for human-machine intelligence fusion. In recent years, brain-controlled spellers, image recognition and mind games are the most popular fields of RSVP-BCI research. Therefore, aiming to provide reference and new ideas for RSVP-BCI related research, this paper reviewed the paradigm design and system performance optimization of RSVP-BCI in these three fields. It also looks ahead to its potential applications in cutting-edge fields such as entertainment, clinical medicine, and special military operations.

An effective therapeutic regimen for hepatic fibrosis requires a deep understanding of the pathogenesis mechanism. Hepatic fibrosis is characterized by activated hepatic stellate cells (aHSCs) with an excessive production of extracellular matrix. Although promoted activation of HSCs by M2 macrophages has been demonstrated, the molecular mechanism involved remains ambiguous. Herein, we propose that the vitamin D receptor (VDR) involved in macrophage polarization may regulate the communication between macrophages and HSCs by changing the functions of exosomes. We confirm that activating the VDR can inhibit the effect of M2 macrophages on HSC activation. The exosomes derived from M2 macrophages can promote HSC activation, while stimulating VDR alters the protein profiles and reverses their roles in M2 macrophage exosomes. Smooth muscle cell-associated protein 5 (SMAP-5) was found to be the key effector protein in promoting HSC activation by regulating autophagy flux. Building on these results, we show that a combined treatment of a VDR agonist and a macrophage-targeted exosomal secretion inhibitor achieves an excellent anti-hepatic fibrosis effect. In this study, we aim to elucidate the association between VDR and macrophages in HSC activation. The results contribute to our understanding of the pathogenesis mechanism of hepatic fibrosis, and provide potential therapeutic targets for its treatment.

Arrhythmogenic cardiomyopathy (ACM), a fatal heart disease characterized by fibroadipocytic replacement of cardiac myocytes, accounts for 20% of sudden cardiac death and lacks effective treatment. It is often caused by mutations in desmosome proteins, with Desmoglein-2 (DSG2) mutations as a common etiology. However, the mechanism underlying the accumulation of fibrofatty in ACM remains unknown, which impedes the development of curative treatment. Here we investigated the fat accumulation and the underlying mechanism in a mouse model of ACM induced by cardiac-specific knockout of Dsg2 (CS-Dsg2 ^-/-). Heart failure and cardiac lipid accumulation were observed in CS-Dsg2 ^-/- mice. We demonstrated that these phenotypes were caused by decline of fatty acid (FA) β-oxidation resulted from impaired mammalian target of rapamycin (mTOR) signaling. Rapamycin worsened while overexpression of mTOR and 4EBP1 rescued the FA β-oxidation pathway in CS-Dsg2 ^-/- mice. Reactivation of PPARα by fenofibrate or AAV9-Pparα significantly alleviated the lipid accumulation and restored cardiac function. Our results suggest that impaired mTOR-4EBP1-PPARα-dependent FA β-oxidation contributes to myocardial lipid accumulation in ACM and PPARα may be a potential target for curative treatment of ACM.

Objective: To retrospectively analyze the efficacy of aerosol inhalation of N-acetylcysteine(NAC) solution combined with bronchoalveolar lavage in children with Mycoplasma pneumoniae pneumonia(MPP) ． Methods: A retrospective study was conducted on 120 children with MPP． According to different treatment methods ，they were divided into combined treatment group (43 cases) ，atomization group (40 cases) and bronchoalveolar lavage group (37 cases) ．Among them，while receiving conventional treatment，children who were treated with aerosol inhalation of N-acetylcysteine alone were included in the atomization group，and those who were treated with bronchoalveolar lavage alone were included in the bronchoalveolar lavage group，and children treated with the combination of the above two treatments were included in the combined treatment group．The clinical efficacy，imaging recovery and incidence of adverse reactions were compared among all groups. Results: Compared the total effective rate among the three groups，there was no significant difference between the atomization group and the bronchoalveolar lavage group (P＞0. 05) ，which were both lower than that of the combined treatment group (P＜0. 05) ; the difference in the improvement rate of lung imaging among the three groups was statistically significant (P＜0. 05) ， the combined treatment group was the highest，and the BAL group was higher than the atomization group ; There was no significant difference in the duration of fever and pulmonary rales between the combined treatment group and the BAL group (P＞0. 05) ，which were shorter than those in the atomization group (P＜0. 05) ; There was no significant difference in duration of cough，shortness of breath and hospital stay between the atomization group and the BAL group (P＞0. 05) ，which were longer than those in the combined treatment group (P＞0. 05) ．There was no serious adverse reactions in the three groups．There was no significant difference in the three groups(P＞0. 05) . Conclusion Compared with single treatment ，N-acetylcysteine solution combined with bronchoalveolar lavage is more effective and has more advantages in the treatment of Mycoplasma pneumoniae pneumonia in children.

OBJECTIVE: To investigate the clinical features and SLC35A2 variant of a case of congenital disorder of glycosylation type IIm (CDG-IIm), and to identify the possible causes of the disease. METHODS: Trio-whole exome sequencing (WES) was used to analyze the gene variant of the children and their parents. The suspicious gene variants were screened for Sanger verification and the bioinformatics prediction was used to analyze the hazard of variant. RESULTS: The clinical manifestations of the child were epilepsy, global growth retardation, nystagmus, myocarditis and other symptoms. MRI showed brain dysplasia such as wide frontal temporal sulcus and subarachnoid space on both sides. Echocardiography showed left ventricular wall thickening and patent foramen ovale. According to the results of gene detection, there was a heterozygous missense variant c.335C>A (p.Thr112Lys) in SLC35A2 gene. The parents were wild-type at this locus, which was a de novo variant. At the same time, there was no report of this variant in the relevant literature, which was a novel variant in SLC35A2 gene. According to the genetic variant guidelines of American College of Medical Genetics and Genomics, SLC35A2 gene c.335C>A (p.Thr112Lys) variant was predicted to be likely pathogenic (PS2+PM2+PP3). CONCLUSION The variant of SLC35A2 gene c.335C>A(p.Thr112Lys) may be the cause of the disease in the child.

BET inhibitor, as an epigenetic regulator inhibitor, reduces the expression of oncogenes such as Myc and Bcl-2, which affects cancer growth and development. However, it has modest activity because of the narrow therapeutic index. Therefore, combination therapy is necessary to increase the anti-tumor effect. Paclitaxel, an anti-mitotic inhibitor, is used as second-line therapy for gastric cancer (GC) as a monotherapy or combination. In this study, we performed RNA sequencing of GC cells treated with iBET-151 and/or paclitaxel to identify the differentially expressed genes associated with possible mechanisms of synergistic effect. We also performed Gene Ontology enrichment and Kyoto Encyclopedia of Genes and Genomes pathway analyses to determine the most enriched terms and pathways of upregulated and downregulated genes. We found 460 genes in which iBET-151 and paclitaxel combination treatment changed more than single-treatment or no-treatment. Thus, additional functional studies are needed, but our results provide the first evidence of the synergistic effect between iBET-151 and paclitaxel in regulating the transcriptome of GC cells.
