Autism spectrum disorders(ASD) effect on children's physical and mental health has been paid more and more attention,and is widely recognized on the importance of early intervention for young children with ASD,effective intervention for the young children with ASD has become a hot pot in this field.This paper introduced the early start denver model,which was highly respected in early intervention for young children with ASD.

Objective:To inspect and improve physician professionalism effectively and preliminarily build eval-uation index system for physician professionalism. Methods:A sample of 240 physicians selected randomly from 8 Three-A hospitals in Shanghai were investigated using a self-designed questionnaire. Then the method of analyt-ic hierarchy process was performed in this study to construct the evaluation model of physician professionalism and determine every index weight. Results: An index system was initially built for physician professionalism evalua-tion. This system comprised three level-1 indexes namely moral quality characteristics, achievement action char-acteristics and vocational cognitive characteristics, as well as 14 level-2 indexes that drew from level-1 including responsibility etc. , at the same time determined their weight distribution. The judgment matrix had completely con-sistency through consistency check, indicating that the weight coefficient can reflect the relative importance of every index. Conclusion:Moral quality characteristics is one of the most important components of physician professional-ism evaluation; responsibility consciousness and vocational ideal are vital for the growth of physicians; lifelong learning and communication skills with high weight reflects needs of modern health care industry development;medical ethics consciousness has a trend of strengthening in physician groups, and enhancing evaluation index sys-tem for physician professionalism has the operability.

Graduate medical education, postgraduate medical education and continuing medi-cal education between China and the United States were compared in order to explore a better physi-cian training system of China. The physician training system of the United States has a series of ad-vantages such as strict access system, uniform training standard and closely linked among each stage, etc. We should make clear medical education standards and strengthen the cohesion between each stage, standardize the management mode and perfect the management system and promote regular as-sessment system.

Objective To investigate the expression of cyclooxygenase-2(COX-2)in breast cancers, and understand its clinical significance.Methods The immunohistochemistry was used to determine the ex- pression of COX-2 in the 40 tissues of breast cancer and 18 adjacent noncancerous mammary tissues.Results The positive expression of COX-2 was detected in 52.5% of breast cancer tissues and in 11.1% of adjacent noncancerous mammary tissues.There was a significant difference in the expression of COX-2 between breast cancer tissues and adjacent noncancerous mammary tissues(P0.05).Conclusion COX-2 was over expressed in breast cancer and correlated with metastatic lymph nodes and HER-2/neu.The expression of COX-2 may play an important role in carcinogen- esis,progression and prognosis of breast cancer.

Objective To explore the effects of alcoholic extracts of traditional Chinese medicines on the post-translational processing and trafficking of tyrosinase.Methods Human YUGEN8 amelanotic melanoma cells were grown in vitro;the cells were incubated with one of the seven traditional Chinese medicines,including Rhizoma Chuanxiong and psoralen.Protein analysis with Western blot,enzymolysis with endoglycosidase H (Endo H),and subcellular localization with laser confocal microscopy were per- formed.The expression,maturity and export from endoplasmic reticulum (ER) of tyrosinase in the treated cells were compared with those in the untreated controls.Results Compared with controls,an approximate- ly 80-kDa,Endo H-resistant tyrosinase doublet,which represented mature glycoform of tyrosinase,was in- creased in melanocytes treated with Semen Cuscutae,and in those treated with Semen Persicae.Within those cells,tyrosinase was distributed outside ER resident protein calnexin.Conclusion Both Semen Cus- cutae and Semen Persicae could induce tyrosinase maturation,stability and export from ER to distal site.

Objective To investigate the value of 99Tcm-methoxyisobutylisonitrile (MIBI) scintigraphy in assessing the preoperative chemotherapy response and multidrug resistance of osteosarcoma.Methods From January 2007 to October 2008, 12 patients (female:4, male:8; mean age:16.3 years,range:8-27 years) underwent early (10min) and delayed (120 min) 99Tcm-MIBI scintigraphy before and after preoperative chemotherapy.Seven cases had osteosarcoma at the distal femurs, 2 at the proximal tibias, 2 at the upper end of humerus and 1 at the fibula.The tumor-to-background ratio (T/B) and washout rate (WR) were calculated.Tumor necrosis was classified according to Huvos criterion after limb salvage surgery.Immunohistochemical staining for P-glycoprotein(gp) was examined.Spearman correlation analysis and t-test were performed.Results According to Huvos criterion, 7 patients were classified as good responders with more than 90% of tumor cell necrosis and 5 as poor responders with less than 90% of tumor cell necrosis.R value (ratio of early phase T/B after and before chemotherapy) was significantly lower in good responders than that in poor responders (0.473 ± 0.21 vs 0.998 ± 0.06, t= 5.342, P= 0.000 ).R value was significantly correlated with the degree of tumor cell necrosis ( rs=- 0.87, P= 0.000 ).WR was significantly higher in patients with positive P-gp expression than that in patients with negative P-gp expression ((38.36 ±18.64)% vs (6.40±5.87)%, t= -3.278, P=0.008).There was significant correlation between the WR and P-gp expression (rs = 0.91, P= 0.001 ).Conclusion 99Tcm-MIBI scintigraphy is a feasible non-invasive technique to assess the chemotherapy response and to detect P-gp expression of osteosarcoma.
