ABSTRACT
Objective@#To explore the prevalence and relevant factors of physical and emotional abuse by parents among children with autism spectrum disorder (ASD), so as to provide basis for intervention program of children abuse.@*Methods@#A total of 221 ASD children from 3 special education institutions in Tangshan were investigated from March to October in 2021, 395 non ASD children from two kindergartens in urban and rural areas were selected by convenient sampling. Parents of these children were invited for online and on site questionnaire survey. The self designed violence questionnaire, Childhood Autism Rating Scale and Patient Health Questionnaire-9 were used to assess violence, severity of autism, depression of parents. Chi square test, Fisher s exact probability method and Logistic regression were used to analyze the influencing factors of violence.@*Results@#About 81.9% of children with ASD and 72.9% of non ASD children experienced violence( P <0.05). The reported rates of physical and emotional violence in ASD children were 74.2% and 73.8% respectively, which in non ASD children were 58.7% and 65.8% respectively. There were significant differences in the 3 types of violence rate between the two groups ( P <0.05). Multivariate Logistic regression analysis showed that boys ( OR =1.70, 95% CI =1.12-2.60), annual per capita income <10 000 yuan( OR =2.43, 95% CI =1.45- 4.08 ), and parental depression ( OR mild =11.01, 95% CI =5.38-22.49; OR moderate =69.97，95% CI =24.25-201.93) were the risk factors for child violence exposure; ASD disease ( OR=1.96，95%CI =1.32-2.92), older age ( OR=1.19, 95%CI =1.01-1.41) and parental depression( OR mild =7.83, 95% CI =3.67-16.74; OR moderate =14.37，95% CI =6.17-33.46) were risk factors for physical violence; boys ( OR =1.62, 95% CI =1.11-2.36), mothers who work in manual labor ( OR=1.68, 95%CI =1.09-2.59) and parental depression ( OR mild =7.69, 95% CI =3.74-15.81; OR moderate =25.37, 95% CI =10.80-59.63) were risk factors for emotional violence( P < 0.05 ).@*Conclusion@#The reported rate of parental violence against children with ASD is high. Mental health promotion and social support for families with ASD should be strengthened.
ABSTRACT
Recombinant human peroxiredoxin-5 (hPRDX5), isolated from anti-cancer bioactive peptide (ACBPs), shows a homology of 89% with goat peroxiredoxin-5 (gPRDX5) and is reported to display anti-tumor activity in vivo. Herein, we explored the effect of hPRDX5 and the responsible mechanism in treating pancreatic cancer. Tumor-bearing mice were randomly divided into normal PBS group and treatment group (n=5; 10 mg/kg hPRDX5). Flow cytometry was employed to examine lymphocytes, myeloid-derived suppressor cell subsets, and the function proteins of natural killer (NK) cells in peripheral blood, spleen, and tumor tissues of mice. Western blot was used to measure the protein expressions of the key nodes in TLR4-MAPK-NF-κB signaling pathway. The rate of tumor suppression was 57.6% at a 10 mg/kg dose in orthotopic transplanted tumor mice. Moreover, the population of CD3+CD4+T cells, NK cells, and CD3+CD8+T cells was significantly increased in the tumor tissue of the hPRDX5 group, while the proportion of granulocytic-myeloid-derived suppressor cells decreased slightly. In addition, after treatment with hPRDX5, the percentage of NK cells in blood increased more than 4-fold. Our findings indicated that hPRDX5 effectively suppressed pancreatic cancer possibly via the TLR4-MAPK-NF-κB signaling cascade; hence hPRDX5 could be a prospective immunotherapy candidate for treating pancreatic cancer.
