Objective: To understand the neglect status among preschool non-only-child in Nantong, and to provide theoretical basis for the prevention and intervention of non-only child neglect. Methods: Using the method of random cluster sampling, a total of 1 141 parents of children from 9 kindergartens in the main urban area of Nantong were investigated with National Neglect Norm Scale for Children aged 3 to 6 years. Results: The neglect rate of preschool children in Nantong City was 28.6%, with neglect score being (40.21±6.67). The neglect rate of non-only-child was 32.6%, with neglect score being (41.14±6.73). The total and physical neglect rate of non-only-child were higher than that of only child, and the total neglect score and physical, emotional, educational, safety, medical neglect dimensional scores were higher than that of only-child, the difference were all statistically significant ( χ 2/ t = 6.21, 17.57; 3.95, 4.98, 3.45, 2.70, 2.01, 3.11, P <0.05). In non-only-child, univariate analysis showed that there were no significant differences in neglect rate and scores among children by gender and family types ( P >0.05); There was no significant difference in the child neglect rate between different age groups and children in different families ( χ 2 =3.59, 2.99, P >0.05), but there was a statistically significant difference in the degree of neglect ( t=2.79, 3.04, P <0.05). The neglect rate and score of non-only-child with high level of family income, parental education and parental relationship was relatively low, while the neglect rate and score in non-only-child whose grandparents serving as primary caregiver were higher ( P <0.05). Multivariate Logistic regression analysis showed that family monthly income less than 5 000 yuan was associated with 2.73 times higher risk of neglect compared to children with family monthly income more than 12 000 yuan. The risk of neglect among children whose grandparents serving as caregivers was associated with 2.17 times higher than children with parental care. The risk of neglect of children with poor parental relationship was 2.29 times higher than that of children with good parental relationship ( P <0.05). Conclusion The neglect among preschool non-only-child in Nantong City is common. Improvement in family economic status, parental care and parent relationship might help reduce neglect among preschool non-only-child.

Chromosomal region maintenance 1 (CRM1) is associated with an adverse prognosis in glioma. We previously reported that CRM1 inhibition suppressed glioma cell proliferation both in vitro and in vivo. In this study, we investigated the role of CRM1 in the migration and invasion of glioma cells. S109, a novel reversible selective inhibitor of CRM1, was used to treat Human glioma U87 and U251 cells. Cell migration and invasion were evaluated by wound-healing and transwell invasion assays. The results showed that S109 significantly inhibited the migration and invasion of U87 and U251 cells. However, mutation of Cys528 in CRM1 abolished the inhibitory activity of S109 in glioma cells. Furthermore, we found that S109 treatment decreased the expression level and activity of MMP2 and reduced the level of phosphorylated STAT3 but not total STAT3. Therefore, the inhibition of migration and invasion induced by S109 may be associated with the downregulation of MMP2 activity and expression, and inactivation of the STAT3 signaling pathway. These results support our previous conclusion that inhibition of CRM1 is an attractive strategy for the treatment of glioma.

Objective: To understand current situation and relations of childhood abuse and psychological capital, providing scientific basis for adolescent mental health promotion. Methods: Stratified cluster sampling method was used to select 1 894 students from junior high schools and senior high schools in Harbin. Questionnaire survey was conducted by using Childhood Trauma QuestionnaireShort Form (CTQ-SF) and Positive Psychological Capital (PPQ). Results: The total rate of childhood abuse among adolescents in the region was 98.3%. In addition to emotional abuse, scores of other dimensions of childhood abuse were higher for boys than for girls(P<0.01). Childhood abuse in rural area was higher than those in urban area except physical abuse(P<0.05). High psychological capital was observed among participants with boys higher in selfefficacy and resilience than that of girls(P<0.05). Psychological capital in urban students was higher than rural students(P<0.05). Except for the negative correlation between sexual abuse and resilience, all other dimensions of childhood abuse were negatively correlated with four dimensions of psychological capital. Stepwise regression analysis showed that emotional abuse, emotional neglect and physical neglect was negatively correlated with all dimensions of psychological capital(P<0.01); Sexual abuse showed negative association with selfefficacy and optimism(P<0.01). Conclusion Childhood abuse is closely related to psychological capital among adolescents in Harbin, suggesting exposure to childhood abuse might confer detrimental effects on psychological capital development.

Objective To study the effect of lipopolysaccharide(LPS)-induced M1 polarization of macrophages on tumor growth.Methods Female Balb/c mice were randomly divided into control group and experimental group.Renca cells were used to establish subcutaneous tumor model.NaCl(100μl/mice,once every two days)or LPS(100μg/mice,once every two days)was injected to the tumor side when the tumor grew to 50mm3.The M1 polarization level of tumor-associated macrophages was detected by flow cytometry.Mouse tumor cell lines(ML-1,MC38,Renca)were divided into three groups:blank group(complete medium with 50％DMEM basal medium),control group(complete medium with 50％medium supernatant of cultured macrophages)and experimental group(complete medium with 50％medium supernatant of LPS pretreated cultured macrophages).The proliferation of tumor cells was detected by cell counting kit-8(CCK-8).The cell cycle and apoptosis of tumor cells were detected by flow cytometry.Results The proportion of tumor-associated macrophages M1 increased after LPS treatment(P<0.001),thus enhancing its anti-tumor function.LPS-induced M1 polarization of macrophages can significantly inhibit the proliferation of tumor cells(Renca:P=0.023,ML-1:P=0.045).LPS-induced M1 polarization of macrophages blocked G0/G1 phase(MC38:P=0.011,ML-1:P=0.022)or S phase(Renca:P=0.022)of tumor cell cycle,and then cell division was inhibited.LPS-induced M1 polarization of macrophages significantly induced apoptosis of tumor cells(Renca:P=0.04,ML-1:P=0.007).Conclusion LPS can play an anti-tumor role by inducing M1 polarization of macrophages.
