Objective:To investigate the prevalence of physical violence against children (PVAC)by parents and to explore possible related factors.Methods:In two primary schools in Liaoning Province,1164 parents of pupils in grade 1 to 6 were surveyed by a self-administered questionnaire anonymously to analyze situation about PVAC and related factors.PVAC was defined as having one or more following parent-to-child behaviors in the past three months:push,or shook a child;pinch,screw,or scratch a child;hit child's buttocks with hand;hit child's hand,foot,arm,leg or back with hand;hit child's buttocks with an object;hit child's face or head with hand;hit elsewhere (not buttocks)with an object;kicked a child with a foot or hit with a fist.Results:Of 1164 parents,53.1% reported that they had minor PVAC (51.0%)or/and severe PVAC (19.8%).Multivariate logistic regres-sion analysis indicated that following factors increased the risk of PVAC:child's male gender (OR =1.49),younger age of children (OR =1.38),poor school performance of children (OR =1.85 ),mother (OR =2.09),parents'childhood physical violence victimization experiences (OR =1.53),parents'supportive or tolerant attitudes towards corporal punishment (OR =3.15),parents'lower awareness of the harmfulness of physical violence against children (OR =2.31),and lower social economic status (OR =1.47).Conclusion:The PVAC by their parents may be com-mon in the present study.Parents'supportive or tolerant attitudes toward corporal punishment and low awareness of the harmfulness of physical violence is the main risk factors of PVAC.
ABSTRACT
Objective To explore the role of integrin in CCL18 for promoting breast cancer SK-3 rd cells invasion and migration process to illuminate the molecular mechanism of CCL 18 for promoting breast cancer SK-3 rd cells invasion and migration process . Methods The flow cytometry was adopted to detect CCL18-induced integrin aggregation ;Western blot was used to detect the focal adhesion kinase(FAK ) activation ,the infiltrating migrationin experiment was adopted to determine the invasion and migration of SK-3rd cells and the siRNAs transfection was used to detect the expression of silence integrin β1 .Results CCL18 promoted the in-tegrinβ1 aggregation in breast cancer SK-3rd cell surface and further promoted the integrin-mediated phosphorylated activation of FAK .Under the reaction of CCL18 ,the cells number of SK-3rd cellular invasion and migration was increased by ten times (P<0 .01) ,which was obviously decreased by siRNA silenced integrin β1 .Conclusion CCL18 promotes breast cancer invasion and mi-gration via integrin aggregation .
ABSTRACT
<p><b>OBJECTIVE</b>To develop a standard Neglect Evaluation Scale which is suitable for rural primary school students in China.</p><p><b>METHODS</b>According to the principle of multi-stage stratified cluster sampling, a field investigation was conducted among primary school students in 28 counties from 7 provinces and 2 municipalities. The questionnaires were self-designed, and determined by multiple rounds of pilots and revisions. Among 5 862 students, 2 792 (6-8 years' old) and 3 070 (9-11 years' old) were investigated by using two kinds of Neglect Evaluation questionnaires, respectively. After project analysis, factor analysis, reliability and validity analysis, the reliability and stability of the scale were tested. Then percentile method was used to determine the evaluation standard to develop and finalize the formal scale.</p><p><b>RESULTS</b>The numbers of the remaining items for 6-8 year-old group and 9-11 year-old group is 69 and 58, respectively, both of which contain six levels of neglect, including body, emotion, health care, education, security, and society. 4 times of factor analysis were conducted in both of the two groups. The factor loadings in these two groups were 0.290-0.700 and 0.276-0.729 respectively. Reliability test results showed that the two kinds of scales' Cronbach alpha coefficient were 0.924 and 0.929 respectively, split-half reliability were 0.891 and 0.904 respectively, the retest reliability were 0.559 and 0.892 respectively, the differences were statistically significant (P < 0.05). The retest reliability among 6-8 year-old group in medical neglect level had no statistical significance, but was close to the cut-off point (P = 0.054). The test results of external validity indicated that both of the two scales could reflect the neglect status of the subjects (P < 0.05), but the subjective and objective evaluation towards neglect were not consistent. The cut-off points for judging whether the children were neglected or not among 6-8 year-old and 9-11 year-old groups were 159 and 137 respectively; and the adjusted values were 160 and 135 respectively.</p><p><b>CONCLUSION</b>The two norm scales developed by this study showed good discriminability, reliability, validity, and stability. The norms developed on the basis of the scales was suitable for the situation of rural students in primary schools in China.</p>

Objective To investigate the culture and proliferation of dendritic cells from human cord blood and malignant pleural effusions and identify the phenotype and the function of them in vitro. Methods Existing DCs were obtained from cord blood and malignant pleural effusions. The DCs were cultured with IL-4, GM-CSF and TNF-?. The morphological properties of DCs were observed by invert optical microscope. The phenotypes of DCs were analysed by flow cytometry. The proliferative bioactivities of T cells activated by DCs were observed with mixed lymphocyte reaction (MLR). Results No remarkable differences were found in the morphology and cellular phenotype of the DC, derived from two different sources, but there was remarkable difference between their culture time. The DCs from two different sources could activate homologous lymphocytes to proliferate mostly. But the capacity to stimulate the proliferation of homologous lymphocytes had remarkable difference. Conclusion Mature DCs could be induced from cord blood and malignant pleural effusions.
ABSTRACT
Objective:To investigate the knowledge, attitudes and practice of child sexual abuse (CSA) prevention education in parents of elementary school pupils.Method:Two hundred and seventy one parents were surveyed by anonymous self-administered questionnaire in five classes of grade 1 to grade 5 of a elementary school. The questions about awareness of CSA and communications on how to prevent CSA with their children were asked.Result:Among this sample, 93.6% of parents approved of school CSA prevention education. Overall, about half parents lack of knowledge of CSA prevention, the communications with their children were also not enough. Only 1.8% of parents had provided books or audiovisuals about CSA prevention for their children. The scores of knowledge, attitudes and practice of CSA prevention education of parents whose parents addressed this in their childhood were significantly higher than those of parents who had no this experience.Conclusions:The research of CSA prevention education in elementary school should be paid more attention, to produce related books and audiovisuals as soon as possible, to increase parents' awareness of CSA prevention.
