Objective To investigate the effect of BQ-123 on the ability of learning and memory and nerve cell autophagy in hippocam-pus in rats with subarachnoid hemorrhage (SAH). Methods 72 male Sprague-Dawley rats were randomly divided into sham group, SAH model group (SAH group) and BQ-123 group with 24 rats in each group. SAH model was established by injecting the autologous blood into cisterna magna twice. The sham group was not injected blood. BQ-123 group received intracerebroventricular injection with BQ-123 18μg 30 minutes before modeling. 6, 24, 72 and 144 hours after modeling, the passive avoidance latency (PAL) and active avoidance reaction rate (AARR) were tested with Shutter Box Test, the nerve cell morphological changes of hippocampus were observed with HE staining, and the expressions of Beclin-1 and LC3-II were detected with immunohistochemical staining. Results Compared with the sham group, the PAL pro-longed, the AARR decreased (P<0.05), the nerve cells in the hippocampus reduced (P<0.05), and the expressions of Beclin-1 and LC3-II in-creased (P<0.05) in SAH group. Compared with SAH group, PAL shortened (P<0.05), AARR increased (P<0.05), the nerve cells in the hip-pocampus increased (P<0.05), and the expressions of Beclin-1 and LC3-II increased (P<0.05) in BQ-123 group. Conclusion BQ-123 can promote the recovery of learning and memory ability, which may relate to the activation of nerve cell autophagy in the hippocampus.

BACKGROUND: Family factor is the main reason for children's psychological and behavioral problems. Seen from the view of systemic family theory, in any circumstances, children's behavioral problems reflect various interpersonal systemic networks among society, school, family, relatives and friends and the relationship of complicated interactions among individuals.Family therapy is an important way to cure children's behavioral problems.OBJECTIVE: To observe whether systemic family rehabilitation is adequate for intervening in children's behavioral problems.DESIGN: Cluster sampling; Contrast observationSETTING: Department of Psychiatry, Kunming Medical College.PARTICIPANTS: A total of 276 students in grade four from Mingtong primary school of Kunming City were selected along with their parents from May 2004 to March 2005. A survey was conducted on students and their parents according to the principle of cluster sampling.METHODS: Self-rating family dynamics scale was used to investigate the characteristics of family dynamics of 276 students in grade four. Achenbach child behavior checklist for parents was adopted to investigate the situation of their children' s behaviors. 57 cases of children with behavioral problems were detected out, and took the families in which the whole family members voluntarily participated in the intervention as interventional group and the families in which any one of the family members did not want to participate in the intervention as abnormal control group. The students and their parents in interventional group were treated with 4-month systemic therapy. 4 months later, resent the above rating scales.MAIN OUTCOME MEASURES: Comparison of family dynamics and children's behaviors between interventional group and abnormal control group before and after intervention.RESULTS: After intervention, changes of family dynamics and children's behaviors in interventional group had taken place, which had statistical difference. The changes as follows: family atmosphere changed from "depressive and hostile" to "harmonious, pleasant, equal and exoteric"; the degree of individuation of family members changed from low level to high; disease concept changed from "regarding the patients as helpless victims" to "regarding them as helpful doers", which realize "softening of disease concept". The total scores of Achenbach child behavior checklist for parents decreased [The scores of questionnaire for fathers before and after intervention were (42.20±22.58) and (28.95±21.90) respectively, and scores of questionnaire for mothers before and after intervention were (50.95±14.60) and (36.40-±15.36) respectively, P < 0.05]. There was no significant difference between the changes of children's behaviors assessed by fathers and mothers in abnormal control group [The scores of questionnaire for fathers before and after intervention were (38.32±17.30) and (37.57±16.45) respectively, and scores of questionnaire for mothers before and after intervention were (45.54±16.02) and (40.14±17.95) respectively, P > 0.05].CONCLUSION: Using the idea and technique of systemic family therapy ,it is feasible and effective to intervene in children's behavioral problems by family therapy.
