RESUMO
Objective@#To analyze the possible responses of parents of young children to Child sexual assault (CSA) and the potential influencing factors, so as to provide evidence for prevention programs of CSA.@*Methods@#Part of the data from "2016-2020 Child Injury Prevention Project" was used to analyze responses to CSA among parents of children younger than 3rd grade in primary school by chi square test and Logistic regression analysis.@*Results@#A total of 4 072 parents were included in the analysis. Among them, 86.8% of parents chose "to solve problems together", 51.0% of parents taking children to a "psychologist", 4.9% of parents "scolding children for being too careless", 2.9% of parents "letting child not disclose abuse" and 6.5% of parents chose "other" coping methods. Parents with foreign nationality [OR(95%CI)=2.58(1.25-5.15)] and lower education level (OR=0.26-0.64) tend to "blame" their children. Mothers [(OR(95%CI)=0.54(0.33-0.90)], higher parental education level (OR=0.27-0.72) were more reluctant to encourage their children to keep quiet. Mothers [OR(95%CI)=1.73(1.32-2.27)], older children (OR=1.33-1.78) and parents with higher education level (OR=1.65-2.99) tend to "accompany". Parents aged 30 or more, and from high school/technical school/technical secondary school tend to take their children to see a "psychologist" [OR(95%CI)=1.39(1.14-1.71), 1.79(1.26-2.53)].@*Conclusion@#Parents universally pay attention to the physical and mental health of children after CSA, but some parents still take negative coping methods, e.g. "blame" and "not disclose". Parenting educational level, duration of parent-child communication and age of children are primary factors associated with parental responses to child sexual assault. This study suggests that prevention secondary injury following child sexual assault should be farther strengthened, while fully considering the characteristics of the educated objects.
RESUMO
Rhein is a primary anthraquinone found in the roots of a traditional Chinese herb, rhubarb, and has been shown to have some anticancer effects. The aim of the present study was to investigate the effect of rhein on the apoptosis of the human gastric cancer line SGC-7901 and to identify the mechanism involved. SGC-7901 cells were cultured and treated with rhein (0, 50, 100, 150, and 200 µM) for 24, 48, or 72 h. Relative cell viability assessed by the MTT assay after treatment was 100, 99, 85, 79, 63% for 24 h; 100, 98, 80, 51, 37% for 48 h, and 100, 97, 60, 36, 15% for 72 h, respectively. Cell apoptosis was detected with TUNEL staining and quantified with flow cytometry using annexin FITC-PI staining at 48 h after 100, 200 and 300 µm rhein. The percentage of apoptotic cells was 7.3, 21.9, 43.5%, respectively. We also measured the mRNA levels of caspase-3 and -9 using real-time PCR. Treatment with 100 µM rhein for 48 h significantly increased mRNA expression of caspase-3 and -9. The levels of apoptosis-related proteins including Bcl-2, Bax, Bcl-xL, and pro-caspase-3 were evaluated in rhein-treated cells. Rhein increased the Bax:Bcl-2 ratio but decreased the protein levels of Bcl-xL and pro-caspase-3. Moreover, rhein significantly increased the expression of cytochrome c and apoptotic protease activating factor 1, two critical components involved in mitochondrial pathway-mediated apoptosis. We conclude that rhein inhibits SGC-7901 proliferation by inducing apoptosis and this antitumor effect of rhein is mediated in part by an intrinsic mitochondrial pathway.
