Objective To research whether systemic family therapy is a useful intervention for behavioral problems. Methods Two hundred and seventy six children who were in the fourth grade of elementary school were assessed by family dynamics questionnaires and their parents were tested by Achenbach Child Behavioral Checklist. Fifty-seven children with behavioral problems were divided into two groups: 20 children and their parents agreed to receive systemic therapy for four weeks and 37 children and their parents who refused this therapy formed the control group.All children and their parents were reassessed after four months. Data were analyzed by SPSS 11.5. Results The characteristics of family dymanmic and children’s behavior improved significantly after systemic therapy. The "depressing and hostile family" at mosphere became "harmonious and open" (P=0.000) and this was also significantly better than the control group after therapy(P=0.000). "Self-differentiation of family members" was significantly improved after therapy (P=0.000) and also was significantly better than the control group after therapy (P=0.005). "Patient is helpless victim" changed to "Patient can do something" (P=0.000) and this was significantly better than the control group after therapy (P=0.003) . Total CBCL score decreased in the treatment group after therapy (P=0.003 for father, P=0.000 for mother). Compared with the control group. Total CBCL score also showed decreases (P=0.033 for father, P=0.014 for mother). Conclusions The techniques of systemic family therapy are practical and effective methods to intervene children’s behavioral problems.
Objective To investigate the changes of pulmonary circulation and right ventricular function after lung volume reduction surgery. Methods We retrospectively analyzed the clinical data of 34 patients of severe chronic obstructive pulmonary disease with single or double lung volume reduction surgery through thoracoscope in our hospital from 2013 through 2014. Ultrasonic testing was conducted peroperatively, on postoperative day 3–5, at 1 month and 3 months after surgery. Results Right ventricular stroke volume (61.00±10.54 ml vs. 38.34±10.04 ml) and right ventricular ejection fraction decreased (58.00%±9.00% vs. 49.00%±10.00%), mean pulmonary arterial pressure (23.35±5.07 mm Hg vs. 29.57±6.32 mm Hg) and total pulmonary vascular resistance (9.28±2.14 mm Hg vs. 12.05±4.36 mm Hg) increased with statistical differences (P＜0.05) on postoperative day 3–5. Right heart ejection fraction was 51%±11% with a statistical increase (P＜0.05) at 1 month after surgery. There was no statistical difference in indicators above between 3 months after surgery and before surgery. Conclusion Changes of pulmonary circulation and right ventricular function may be temporary. Right ventricular dysfunction decreases, pulmonary arterial pressure, and total pulmonary vascular resistance increases on postoperative day 3–5 d. But the changes gradually recover in 1–3 months after surgery, and could be gradually restored to preoperative level.
