ObjectiveTo explore the characteristics of family dynamics in different developmental disorders.MethodsIn this study cross-sectional survey were used.Parents of 69 Autistic Disorder (AD) children,18 Asperger Syndrome (AS) children,51 Mental Retardation (MR) children and 69 Normal Group (NG) children were investigated by Self-rating Inventory of Systemic Family Dynamics to assess their family dynamic characteristics.SPSS18.0 package for statistics were used.ResultsCovariance analysis by controlling children's age showed:there were significant differences in both fathcrs'and mothers'family atmosphere,systemic logic and disease concept dimension among the tour groups ( Ffather =5.355,3.946,6.961,P＜ 0.05 ; Fmother =4.325,2.977,5.878,P ＜ 0.05 ).Pairwise comparison indicated that scores of both fathers'and mothers'family atmosphere,disease concept dimension in AD ( father ( 24.24 ± 5.89 ),( 10.60 ± 2.81 ) ; mother ( 24.90 ± 8.18 ),( 10.59 ± 3.07 ) ),AS ( father (24.67±7.07),(11.39 ±2.52); mother (26.83 ±6.24),(10.61 ±2.55)),MR(father (25.02 ±7.89 ),( 10.94 ± 2.94 ) ;mother( 24.02 ± 7.59 ),( 11.42 ± 3.54 ) ) groups were significant higher than that of NG (father (20.19 ± 5.75 ),( 8.74 ± 2.63 ) ; mother ( 20.87 ± 5.85 ),( 8.88 ± 2.64 ) ) (P ＜ 0.05 ).Scores of both fathers'and mothers'systemic logic dimension in MR group( father ( 24.26 ± 4.36 ),mother( 23.54 ± 4.58 ) ) were higher than that of NG(father (21.61 ±3.97),mother (21.03 ±3.66),P＜0.01).ConclusionIn families of AD,AS and MR children,the family atmosphere is more boring,parents are more likely to consider themselvesfull of victims.Parents of MR children are more prone to one or the other way of looking at problems.

Objective To investigate the expression of survivin in keloid, and its significance in the development of keloid. Methods Tissue samples were obtained from 25 patients with keloid (12 males and 13 females, aging from 4 to 44 years with a disease course of 1-18 years), and 15 normal skin samples obtained from surgical operation served as the controls. Streptavidin-biotin-peroxidase complex (SABC) method was applied to detect the expression of survivin in these samples. Results No expressin of survivin was observed in normal controls, while it was expressed in 80.0% (20/25) of the keloid samples with the predominant distribution in fibroblasts and vascular endothelial cells. The positivity rates of survivin were 57.14% (4/7), 81.81% (9/11) and 100% (7/7) in tissues of low-grade, moderate-grade and high-grade keloid, respectively, with no significant difference among the three groups (P = 0.133 ). Similarly, no signifi- cant difference was observed in the positivity rate of survivin between recurrent patients and untreated patients (90.91% (10/11 ) vs 71.43% (10/14), P = 0.341 ). Conclusion Survivin might play a role in the development of keloid.

Objective To observe the influence of dexamethasone on the gene expression profiling of PBMCs from patients with internal heat due to Yin deficiency-type SLE. Methods The PBMCs from 3 patients with internal heat due to Yin deficiency-type SLE were incubated with dexamethasone of 10-6 g/L for 48 hours followed by the detection of gene expression profiling of PBMCs by a GeneChip. Results The incubation with dexamethasone upregulated the expressions of 85 genes and downregulated those of 126 genes in PBMCs from the SLE patients. Conclusions Dexamethasone can regulate the expressions of numerous clusters of genes in PBMCs from patients with internal heat due to Yin deficiency-type SLE, and functional proteins encoded by these genes are located at various organelles and regions of cells. Not all the results of gene regulation by dexamethasone favor the relief of SLE. To study the regulation of genes may be beneficial to the elucidation of mechanisms underlying the therapeutic effect of dexamethasone on SLE.

Objective To obtain the information of the 2009 influenza outbreak and the variations of influenza virus strains in quanzhou, and explore the relationship between the genetic variation of influenza virus and influenza epidemic. Methods During the influenza outbreak in quanzhou,one hundred and ninetyeight throat swabs specimens from the patients with influenza were collected. Viruses were isolated with MDCK cells and identified with serological test, followed by real-time RT-PCR. RNA of four influenza virus strains were extracted, then HA1 gene was amplified by RT-PCR. The purified PCR products were sequenced. The data were analyzed with the software DNAstar megalign. Results Total 98 pieces of H3N2 subtype influenza virus nucleic acid were detected in 198 throat swabs specimens,among which 62 influenza virus strains were identified as subtype influenza A( H3N2 ). The sequencing results of HA1 gene in these positive strains showed that their genetic characterization were more closed to strains A/Ningbo/333/2008 with a nucleotide homology of 98.7%, which was 96.8% as compared with A/Xiamen/70/2004. The amino acids sequences deduced from the nucleotide sequences in HA1 region of the isolated strain had 7 mutant sites compared with A/Brisbane/10/2007 vaccine strain. One variant amino acids were found located in the antigenic determinant sites A( 144 ), two were in the sites B( 158,189 ). Phylogenetic analysis also confirmed the difference in HAl domain. Conclusion The influenza virus strains causing the flu outbreak among some communities of quanzhou in 2009 are subtype influenza A ( H3N2 ), whose genetic characterization and antigenicity were different from the vaccine strain.
