Objection: To study the characteristics of shame of patients with neurosis. Method: 52 patients with nuclear neurosis were evaluated by SCL-90, Shame Scale, and Children Trauma Questionnaire. The control group (n=30) was evaluated just by Shame Scale. Results:The total score of Shame Scale and the subscores of each factor were all higher in neurotic patients than in control group (total score 69.0?20.4/48.7?10.2, personality 29.4?9.7/19.8?5.8, behavior 23.5?6.5/18.0?4.2, body 8.3?3.4/5.7?2.2, family 7.7?3.9/5.2?1.7, t=3.15~5.09,P=0.001or

Objective:To get the prevalence of attention-deficit hyperactivity disorder and in Children. Methods:The subjects were 2188 children who were 4~16 year-old in Wuhan. We had their parents filled the investigation forms. Diagnosis was made according to criterion of attention-deficit hyperactivity disorder in DSM-IV. Results:of behavior problems were got through Achenbach Behavior Questionnaires. Those who were diagnosed as ADHD were classified into three subtypes: predominantly inattentive type; predominantly hyperactive-impulsive type and com-bined type. All suspicious patient and their parents were invited to have the diagnostic talk. Results: (1) The rate of ADHD was 13.58%. ADHD-C, 2.63%; ADHD-I, 8.27%; ADHD-HI, 2.68%. The male, 18.57%; female,8.78%. The ratio of male: female was 2.24:1。(2) There was significantly difference of rate of ADHD between age groups. The rate of 4~5 years-old was 15.88%, that for 6~11 years-old was 15.85%; and for 12~16 yeas-old, 9.98%. The rate of ADHD decreased by aging, especially the group of ADHD-HI. But the rate of ADHD-I was still increased, especially the male group of 6~11 years-old, 12.19%. (3) There was significantly difference of sociality ability between ADHD children and the normal. (4) No matter which age and sex, the scales of behavior problem of ADHD children were higher than the normal children. And the number of factors of behavior problem of ADHD children increased by ag-ing.Conclusion: The rate of ADHD-I was the highest in the three subtypes defined by DSM-Ⅳ, especially among boys 6~11-years-old. The rate of ADHD is significantly associated with sex and age.

BACKGROUND:Bone morphogenetic protein 7 (BMP-7) can induce bone and cartilage formationin vivo, and induce chondrogenic and osteogenic differentiation of mesenchymal cels in muscles and around the vessels.
OBJECTIVE:To observe the structure of domestic tantalum-muscle interface fibrous capsule, growth of muscle and smal blood vessels into the porous tantalum and the ability of ectopic osteogenesis after implantation of porous tantalum loaded with BMP-7 into the erector spinae of rabbits.
METHODS: Porous tantalum slices loaded with BMP-7 (experimental group) and porous tantalum slices (control group) were implanted into the erector spinae muscle of New Zealand white rabbits. And the porous tantalum slices with surrounding muscle tissues about 0.5 cm thick were removed at 2, 4, 8 weeks after implantation, and observed under scanning electron microscope for hematoxylin eosin staining, Masson staining and hard tissue slice observation.
RESULTS AND CONCLUSION:(1) Hematoxylin-eosin staining: Fibrous capsule formation was observed around the materials in the two groups, and with the extension of time, the fibrous capsules were slightly dense, and thinned. There was no obvious inflammatory reaction in the interface between the material and the muscle. There was no significant difference between the two groups in the fibrous capsules thickness. (2) Scanning electron microscope: 2 weeks after the surgery, a smal amount of colagen and muscle fibers were formed in the porous tantalum pores in the two groups, and some of colagen fibers attached to the pore wals. At 8 weeks after the surgery, al the pores of porous tantalum were ful of muscle fibers that were combined with the pore wal closely. There was no significant difference between the two groups. (3) Hard tissue slices: 2 weeks after the surgery, a smal amount of fibroblast cels and muscle fibers grew into the pores of porous tantalum in the two groups and new capilaries grew into the pores of porous tantalum in the experimental group. At 8 weeks after the surgery, the porous tantalum and al the pores were ful of muscle fibers that were combined with the pore wal closely, the number of smal blood vessels and cels decreased, and the tantalum and the muscle were fused closely. (4) Masson staining: 8 weeks after the surgery, a large number of mesenchymal cels, ossein and cartilage matrix formed in the muscle gaps and a few cartilage bone tissues were formed in the experimental group, but no cartilage was found in the control group. The study showed that porous tantalum carrying BMP-7 has good biocompatibility and osteogenic induction ability. Subject headings: Tantalum; Bone Morphogenetic Protein 7; Tissue Engineering.
