Objective:To investigate communication and adaptive function of children with Asperger Syndrome (AS).Methods:The adaptive function of two groups,123 with AS and 23 normal, were investigated with Adaptive Ability Scale for Children; Intelligence were measured with WISC; Communication behaviors of AS children were also investigated. Results:Significant differences were found between the two groups in total score of adaptive abilities and in domains of socialization, communication and self-administration; Abnormal communication behaviors were found in AS children。Conclusion: AS children demonstrated abnormal communication behaviors and deficits in social adaptive abilities.Early diagrosis and intervention can reduce children's adaptive trouble after entering school.

Aim To investigate the effect of irbesartan and spironolactone on expressions of connective tissue growth factor(CTGF),P-p38MAPK proteins during vascular remodeling in renovascular hypertensive rats(RHR).Methods Renovascular hypertension was induced by two kidney one clip(2K1C)operation.8 weeks later,RHRs were given irbesartan or(and)spironolactone for 8 weeks.After 8 weekstreatment,the morphometric measurements were performed in the mesenteric arterioles.Concertration of carboxyterminal propeptide of typeⅠprocollagen(PⅠCP)and N-terminal propeptide of type Ⅲ procollagen(PⅢNP)in blood serum was measured by enzyme linked immunosorbent assay method,and the media collagen area was assessed by collagne-specific Picro-sirius red staining with computerized video processing.Expressions of collagen type I,CTGF,P-p38MAPK proteins were detected using immunohistochemistry respectively.Results The arterial systolic pressure was attenuated significantly after the treatment of irbesartan,and this effect could not be enhanced by spironolactone.The media thickness over lumen ratio,media cross-sectional area over luminal area ratio of mesenteric arterioles,concertration of PⅠCP and PⅢNP,media collagen area,and expression of collagen typeⅠwere significantly increased in RHRs but ameliorated by irbesartan and spironolactone.Meanwhile,the expressions of CTGF,P-p38MAPK proteins were up-regulated in RHRs but blunted significantly after the treatment of irbesartan and spironolactone.The combined treatment had the synergic effects.Conclusions There is a synergistic effect of attenuating extracellular matrix(ECM)producing and amelioration of vascular remodeling(VR)by combined use of irbesartan and spironolactone.It maybe related to the expressions of CTGF and P-p38MAPK proteins down regulated by these two drugs.

OBJECTIVE:To study the effects of goserelin on vascular growth factor and immune function of rats with prostatic hyperplasia. METHODS:Rats were selected to establish prostatic hyperplasia model and randomly divided into model group,gose-relin low-dose,medium-dose and high-dose groups (0.4,0.8,1.2 mg/kg);normal rats were selected as normal control group, with 10 rats in each group. Normal control group and model group were given normal saline intragastrically,and goserelin groups were given relevant dose of drugs intragastrically,once a day,for consecutive 25 days. The prostate volume,wet weight,prostatic index of rats were detected as well as positive cell area of VEGF,TGF-β1,FGF,CD4 and CD8 in prostate tissue. RESULTS:Compared with normal control group,prostate volume,wet weight,prostatic index,positive cell area of VEGF,TGF-β1,FGF, CD4 and CD8 were all increased in model group (P<0.05). Compared with model group,the above indexes of goserelin groups were all improved (P<0.05),especially those in medium-dose and high-dose groups were better than in low-dose group (P<0.05);there was no statistical significance between medium-dose group and high-dose group(P>0.05). CONCLUSIONS:Gosere-lin can relieve prostatic hyperplasia of rats,reduce the expression of VEGF in prostate tissue and regulate immune function.

Objective To study the effects of enteral immunonutrition on immune function in patients with multiple trauma. Method A total of 32 patients with multiple trauma admitted to general ICU in ChangZheng hospital, Shanghai from March 2007 to May 2008 were randomly (random number) divided into two groups,enteral immunonutrition group (EIN group, n = 16)and the general formula enteral nutrition group (EN group, n = 16).Two groups of patients on the third day after injury began to accept the EIN and the general formula EN which respectively support at least 14 days. The patients peripheral blood lymphocyte count (TLC), immunoglobulin (IgG,IgM, IgA) ,and T-lymphocyte subsets (CD3, CD4, CD8, CD4/CD8) were detected on the day of the group formation, the seventh and the fortteenth day of the nutritional support. Results TLC, IgG, IgM, IgA, CD4 and CD4/CD8 ratio were significantly higher in EIN Group on the 7th and 14th day than that on the first day ( P ＜0.05), and extended with the EIN and sustained increase. All immunization indicators of EN group on the 7th day were no significant changes compared with the day of the group formation, and on the 14 th day TLC, IgG, IgM,IgA, CD4 and CD4/CD8 ratio were significantly higher than that on the day of the group formation ( P ＜ 0.05),but were significantly lower than that in the EIN group on the 14th day ( P ＜ 0.05). Conclusions Compared with the general formula EN, EIN is more helpful to restore and increase the humoral and cellular immune function in early post-multitraumatic phase.

Objective To explore the mechanism of Xiaoying decoction on experimental autoimmune thyroiditis (EAT) rats in view of regulatory T cells and Th17 cells.Methods SD rats were divided into five groups,normal control group,model control group,tripterygium glycoside group,Xiaoying decoction low and high dose groups.Except for normal control group,the other groups were established the model of EAT.Rats in the Xiaoying decoction low,and high dose groups were given Xiaoying decoction of 17.24 and 68.95 g·kg-1;rats in the tripterygium glycoside group were given tripterygium glycoside 6.25 mg·kg-1.The serum free triiodothyronine(FT3),free thyrocyte(FT4) and thyroglobulin antibody were detected by RIA method.Thyrocyte morphology was observed under optical microscope.The expression levels of Foxp3 mRNA and IL-17 mRNA were detected by real-time PCR.The changes of Treg cells and Th17 cells were analyzed by flow cytometry.Results Compared with the normal control group,FT3,FT4 and TgAb were increased in the model control group (P ＜0.01,P ＜0.01,P ＜0.05).Compared with the model control group,FT3,FT4 and TgAb were decreased in tripterygium glycoside group and Xiaoying decoction high dose group (P ＜ 0.05).The infiltration score in the normal control group,model control group,tripterygium glycoside group,Xiaoying decoction low and high dose groups were 0,4,4,3.5,2.Compared with model control group,the infiltration was improved (P ＜0.01).Foxp3 mRNA expression was decreased while IL-17 mRNA increased in the model control group as compared with the normal control group(P ＜ 0.01).In contrast,the expression of Foxp3 mRNA was increased and IL-17 mRNA expression was decreased in Xiaoying decoction low and high dose groups,tripterygium glycoside group as compared with the model control group (P ＜0.05).Compared with the normal control group,rats in the model control group had fewer Treg cells and more Th17 cells (P ＜0.01).Compared with the model control group,the percentage of Treg cells was elevated and Th17 cells was reduced in tripterygium glycoside group and Xiaoying decoction high dose groups (P ＜ 0.01).Conclusion The therapeutic mechanism of Xiaoying decoction on EAT rats may be related to changing the percentage of regulatory T cells and Th17 cells with up-regulating the expression of Foxp3 mRNA and down-regulating the expression of IL17mRNA.

Radiation?induced heart disease ( RIHD) is a common type of radiation?induced damages in chest radiotherapy. There are no obvious short?term symptoms in patients with RIHD. However, RIHD causes irreversible permanent damages to the heart over time, which undermines the quality of life. Patients with severe RIHD even have a risk of death from myocardial infarction caused by coronary atherosclerosis. This paper summarizes the research advances in epidemiology, diagnosis, mechanisms of radiation?induced injury in various parts of the heart, radiotherapy techniques, and treatment. Reduction in radiation range and dose, early diagnosis, and early treatment are recommended for patients to reduce heart injury and improve the quality of life.
