Objective To study whether early treatment of aminophylline can protect renal function in neonates with perinatal asphyxia.Methods 60 neonates with perinatal asphyxia were randomly divided into 2 groups.Within the first hour after birth,the treatment group(30 cases)received intravenously a single dose of aminophylline(5mg/kg),and the control group(30 cases)received placebo of water.Urinary Nacety-?-D-Amino-Glucosidase(NAG)activity was recorded everyday during the first 3 days of life.Heart rate,respiratory rate and blood pressure were recorded per 4h.Results Urinary NAG activity of treatment group at 48h and 72h after birth were significantly lower than that of control group(P

Objective To study the efficacy of repetitive transcranial magneticstimulation(rTMS) of the right prefrontal cortex combined paroxetine for patients with obsessive-compulsive disorder ( OCD) under doubleblind , sham-controlled conditions. Methods Patients were randomly assigned to 2 sessions of real ( n = 32) or sham ( n = 31) rTMS and both group received Paroxetine treatment. rTMS treatments lasted 20 minutes,and the frequency was 10 Hz and the intensity was 100% of motor threshold for real rTMS. Psychopathology was assessed by HAMA.Y-BOCS before the treatment,immediately after the experimental treatment,and 1,2,4,6 weeks after the experimental treatment by an independent reviewer. Results In combined therapy group,9(32. 14% ) recovered, 10(35.71% ) remitted,5( 17. 86% ) improved,4( 14. 29% ) remained unresponsive. In contrast,there were 4(16.36%) recovery,5(21.82%) remission, 10(38.18% ) improvement,6(23.64% ) unresponse in drug therapy group. The outcome of ITT showed all the patients in the two groups significant improvement (the scores of YBOCS( F=56.258, P=0.000) ;the scores of HAMA( F=41.675, P=0.000) after the treatment,but the effectiveness in the combined therapy group was better than that in the drug therapy group (the scores of Y-BOCS, F= 13.652, P=0.028;the scores of HAMA, F= 11.632, P=0.031). Conclusions Repetitive transcranial rTMS of the right prefrontal cortex combined paroxetine is more effective than paroxetine only in treatment of refractory OCD.

Objective To explore the effects of community-based comprehensive intervention on social function and quality of life of patients with bipolar disorder. Methods 244 bipolar disorder patients were assigned into control group (n=119) and intervention group (n=125). The control group accepted antipsychotics only, and the intervention group accepted community-based comprehensive intervention in addition. They were assessed with Social Disability Screening Schedule (SDSS) and Generic Quality of Life Inventory-74 (GQOLI-74) before and 6, 12 months after treatment. Results The SDSS score was lower (P<0.05) and the GQOLI-74 score was higher (P<0.05) in the intervention group than in the control group. Conclusion Community-based comprehensive intervention can improve the social function and quality of life of patients with bipolar disorder.
