ObjectiveTo explore the relationship of one-child attachment and parerttal attachment,as well as the effect of family income and parental education on children's attachment.Methods 350 children aged over 12 years from primary school grade 5 to high school grade 3 in Nanjing were selected in two classes each grade in cluster sampling method as research objects.These children and their parents were measured by General questionnaire,Experiences in Close Relationships Inventory( ECR ) and Adolescent Attachment Inventory.The data of the questionnaires were coded for statistical analysis-Pearson conrelation to analyze the relationship of one-child attachment and parental attachment and Analyze of variance to explore the influence of family income and parental education on children's attachment.ResultsThere was a significantly negative relation(r =-0.132,P=0.014)between one-child family negative dimension and mother avoidance dimension,and a significant correlation (r =0.131,P =0.015 ) between one-child family negative dimension and mother anxiety dimension.The interaction of family income and parental culture was significant in affinity attachment of one-child (F =3.641,4.052,P =0.006,0.003).ConclusionThis study finds that one-child is more attached to their mothers than their fathers.Family income and parental education affect the attachment of one-child.

Objective To investigate the effects of Gegenqinlian Decoction on the IL-1β level in the patients with chronic periodontitis.Methods Seventy patients with chronic periodontitis were divided into the observation group and control group,35 cases in each group.The control group was given the periodontal basic treatment.On the basis of the control group,the observation group was given Gegenqinlian Decoction.The probing depth,attachment level and bacterial plaque index level before and after treatment were compared between the two groups.The levels of IL-1β and IL-6 in serum and gingival crevicular fluid were measured before and after treatment in the two groups.Results The total effective rate in the observation group was 94.29%,which was significantly higher than 71.43% in the control group,the difference was statistically significant (χ2=6.437,P<0.05).After treatment,the probing depth,attachment level and bacterial plaque index in the two groups were significantly decreased (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).The levels of IL-1β and IL-6 in serum and gingival crevicular fluid after treatment in the two groups were decreased significantly (P<0.05),but which in the observation group were significantly lower than those in the control group,the difference was statistically significant (P<0.05).Conclusion Gegenqinlian decoction can significantly reduce the IL-1β level in the patients with chronic periodontitis,reduces inflammation reaction and improves the therapeutic effect.
