Objective: To explore the effects of comprehensive intervention on the mental health problems of teenagers from divorced family. Methods: The Scl-90,the Social Avoidence and Distress Scale,and the Coping Style Scale were used.60 subjects were divided into intervention group and control group.The intervention group received 20-30 units of counseling,and an intervention program that aimed to parent rearing behavior and social support system was set up.Results: After the intervention program,the total SCL-90 scores,factor scores,the social avoidence,anxiety, and negative coping scores were significantly lower than those of the control group( P <0.01).Conclusion: Comprehensive intervention was effective to improve the mental health status of teenagers from divorced family.
为克服目前合成方法存在收率较低,反应时间长、产品分离困难等不足,本文以β-D-葡萄糖、乙酰溴为原料,经乙酰化、溴代反应合成了糖基体2,3,4,6-O-四乙酰基-α-D-溴代葡萄糖,再与4-羟基苯甲醛衍生物经糖苷化反应合成了5种4-甲酰基苯基(2,3,4,6-O-四乙酰基)-β-D-葡萄糖苷衍生物。在合成4-甲酰基苯基(2,3,4,6-O-四乙酰基)-β-D-葡萄糖苷衍生物的过程中,采用10%(质量分数) Na OH溶液为缚酸剂,三(3,6-二氧杂庚基)胺(TDA-1)为相转移催化剂,反应物的收率为61%～69%,并应用核磁共振技术确定了产品的结构。该方法具有产品收率较高,反应温和、操作简单等优点。
