This study used the latent class analysis (LCA) to identify and classify Chinese adolescent children's aggressive behaviors. It was found that (1) Adolescent children could be divided into four categories: general children, aggressive children, victimized children and aggressive victimized children. (2) There were significant gender differences among the aggressive victimized children, the aggressive children and the general children. Specifically, aggressive victimized children and aggressive children had greater probabilities of being boys; victimized children had equal probabilities of being boys or girls. (3) Significant differences in loneliness, depression, anxiety and academic achievement existed among the aggressive victims, the aggressor, the victims and the general children, in which the aggressive victims scored the worst in all questionaires. (4) As protective factors, peer and teacher supports had important influences on children's aggressive and victimized behaviors. Relative to general children, aggressive victims, aggressive children and victimized children had lower probabilities of receiving peer supports. On the other hand, compared to general children, aggressive victims had lower probabilities of receiving teacher supports; while significant differences in the probability of receiving teacher supports did not exist between aggressive children and victimized children.
Introduction: Studies have found that adolescents' subjective well-being (SWB) shows a downward trend with age. The improvement of adolescents' SWB is therefore an urgent problem. According to previous studies, altruism may be an effective way to improve adolescents' SWB. We conducted an Integrative Educational Intervention of Altruism (IEIA) for the irst time to determine whether altruism intervention can effectively improve adolescents' SWB. Methods: We conducted an IEIA on adolescents in an experimental group for 14 weeks using preand post-test experimental designs with peer groups. The participants were randomly recruited from a junior high school in East China and included 280 Grade 8 students (138 boys and 142 girls; mean age: 14.53 years). Before and after the experiment, the adolescents completed measures of SWB using the Multidimensional Students' Life Satisfaction Scale and Happiness Scale. Results: From the pretest, we found no signiicant differences in friendship, academic, freedom, school and social satisfaction or positive emotions between the control and experimental groups. However, in the post-test, the life satisfaction and positive emotions of the experimental group were rated signiicantly higher than those of the control group. These results show that experimental intervention can effectively improve adolescents' life satisfaction and positive emotions. Conclusions: Altruistic intervention was identiied as an effective way to improve adolescents' SWB. It is thus necessary to cultivate altruistic environments, to enrich altruistic education programs, and to carry out voluntary services for the beneit of the public. Altruistic adolescents themselves may beneit when helping others.
Purpose This study aimed to evaluate the safety and efficacy of chimeric antigen receptor (CAR) disialoganglioside 2 (GD2)-specific (4SCAR-GD2) T cells for treatment of refractory and/or recurrent neuroblastoma (NB) in pediatric patients. Experimental design A phase I clinical study using 4SCAR-GD2 T cells for the treatment of NB in pediatric patients was conducted. This study was registered at www.clinicaltrials.gov (NCT02765243). A lentiviral CAR with the signaling domains of CD28/4-1BB/CD3ζ-iCasp9 was transduced into activated T cells. The response to 4SCAR-GD2 T-cell treatment, and 4SCAR-GD2 T-cell expansion and persistence in patients were evaluated. Toxicities were determined based on the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v4.03. Results Twelve patients were enrolled and finally ten patients were included in this clinical trial which started from January 1, 2016, to August 1, 2017. These patients had progressive disease (PD) before CAR T-cell infusion. After 4SCAR-GD2 T-cell treatment, 6 (6/10) had stable disease (SD) at 6 months, and 4 (4/10) remained SD at 1 year and alive after 3–4 years of follow-up. Six patients died due to disease progression by the end of July 1, 2020. The median overall survival (OS) time was 25 months (95% CI, 0.00–59.43), and the median progression-free survival (PFS) time was 8 months (95% CI, 0.25–15.75). Grade 3 or 4 hematological toxicities were the common adverse events frequently occurred after fludarabine and cyclophosphamide (Flu/cy) chemotherapy. Grade 1–2 toxicities such as cytokine release syndrome (CRS) and neuropathic pain were common, but were transient and mild. Conclusions The 4SCAR-GD2 T-cell therapy demonstrated antitumor effect and manageable toxicities, indicating its potential to benefit children with refractory and/or recurrent NB.
BackgroundCell-mediated immunity is often suppressed in patients with hematological malignancies. Recently, we found that low T cell receptor (TCR)-CD3 signaling was related to abnormal expression of the negative regulator of nuclear factor kappa B (NF-κB) A20 in acute myeloid leukemia. To investigate the characteristics of T cell immunodeficiency in lymphomas, we analyzed the expression features of A20 and its upstream regulating factor mucosa-associated lymphoid tissue lymphoma translocation gene 1 (MALT1) and genes downstream of NF-κB in patients with different lymphoma subtypes, including T cell non-Hodgkin lymphoma (T-NHL), B cell non-Hodgkin lymphoma (B-NHL) and NK/T cell lymphoma (NK/T-CL).MethodsReal-time PCR was used to determine the expression level of the MALT1, MALT-V1 (variant 1), A20 and NF-κB genes in peripheral blood mononuclear cells (PBMCs) from 24 cases with T-NHL, 19 cases with B-NHL and 16 cases with NK/T-CL, and 31 healthy individuals (HI) served as control.ResultsSignificantly lower A20 and NF-κB expression was found in patients with all three lymphoma subtypes compared with the healthy controls. Moreover, the MALT1 expression level was downregulated in all three lymphoma subtypes. A significant positive correlation between the expression level of MALT1 and A20, MALT1-V1 and A20, MALT1-V1 and NF-κB, and A20 and NF-κB was found.ConclusionsAn abnormal MALT1-A20-NF-κB expression pattern was found in patients with lymphoma, which may result a lack of A20 and dysfunctional MALT1 and may be related to lower T cell activation, which is a common feature in Chinese patients with lymphoma. This finding may at least partially explain the molecular mechanism of T cell immunodeficiency in lymphomas.
Objective The objective of this work is to compare posttraumatic stress symptoms (PTSS) between families of children on cancer treatment and families of healthy children in China and to analyse the association among child PTSS, parent PTSS, and depression in the cancer group. Methods Participants were children on cancer treatment (n = 91) and their parents (n = 91), and healthy children (n = 114) and their parents (n = 96). The children were asked to self‐report PTSS, and the parents completed self‐reported measures of PTSS and depression. Results Although the prevalence of probable PTSD in children on cancer treatment was higher than that in comparisons (8.79% vs. 0.88%, P < 0.01), no statistic differences in PTSS levels were found between the two groups (P > 0.05). However, significant differences in PTSS levels and the prevalence of severe PTSS (21.98% vs. 1.04%) between parents of children with cancer and comparisons were observed (P < 0.001). Parent PTSS and depression were positively associated with child PTSS in the cancer group (P < 0.01). Conclusion The prevalence of probable PTSD in Chinese children with cancer was low, but PTSS was remarkably prevalent in their parents. Greater parent PTSS and depression were related to greater child PTSS. Results underline the importance to provide supportive psychological care for Chinese parents of children undergoing cancer treatment.
This study investigated the characteristics and development of peer support networks in an effort to unravel the role of friendship in this developmental process. The relationships between friendship networks and peer support networks were explored, and the influence of dyadic and triadic friendships on the development of peer support relationships was examined. Two waves of data were collected among a sample of adolescents in six Chinese junior high schools (n = 913 students from 28 classrooms; mean age = 14.13 years; 50.49% boys), and classroom friendship networks and peer support networks were analyzed. The results showed that peer support networks were sparse, hierarchical, and sex-segregated. Furthermore, peer support networks and friendship networks partially overlapped. Friends tended to have similar support-seeking and support-providing ties. Longitudinal multiplex social network analysis revealed that peer support networks changed moderately over time, and friendships played various roles in the development of peer support networks. Dyadic friendships improved the formation of peer support ties. A mutual friend improved the formation of support relationships between two students when the mutual friend chose the two students as friends, but a mutual friend also hindered or had no effects on the formation of support relationships in other cases. The implications for educators to improve peer support networks are presented, and directions for future research are discussed.
