objective: To study the effects of BMP on the growth of osteosarcoma cells. Methods: Human antisense BMP2 retrovirus expression vector was constructed and transfected into human osteosarcoma OS 9901 cells by Lipofect AMINE. Positive cell clones were selected with G 418. The expression of BMP and PCNA were determined by immunohistochemical methods, image analysis and expressed as grey level. The morphology and cell cycle distribution of the cells were studied by electronmicroscope and flowcytometry respectively. Results:The grey levels of BMP and PCNA in the transfected cells were 198.4?8.51 and 197.3?3.22, those of the control were 135.1?12.32 and 142.9?8.47,respectively. G 1, G 2 and S phase cells were 51.9%,18.2% and 22.7% in the cell cycle of transfected cells, while those of the control were 52.8%,11.1% and 36.1%, respectively.Increased lysosome and small pieces of chromatin were observed in the transfected cells under electronmicroscope. Conclusion:Transfection of antisense BMP2 may inhibite the expression of BMP and proliferating activity of osteosarcoma cells.

Objective:To develop a UV optical fiber in situ process monitoring method for the dissolution behavior of five cepha-lexin solid dosage forms and compare the drug dissolution behavior of different cephalexin preparations. Methods: The dissolution of five different cephalexin preparations was on-line monitored according to the dissolution method for cephalexin tablets in Chinese Phar-macopeia (2010 edition) combined with a six channel optical fiber chemical sensor in situ dissolution monitor. Results:The dissolu-tion curves could show the drug release characteristics of different cephalexin preparations, and the five different preparations exhibited various drug release features. Conclusion:An in-situ, real time, on-line and process analysis of dissolution can be obtained by optical fiber dissolution test system automatically. The release characteristics of different preparations can be presented through dissolution curves directly, which can provide reference for the overall assessment of drug internal quality and clinical medication.

Objective: To develop parental punishment style the questionnaire. Methods: Based upon previous literature about parental punishment style and expert interview, data were collected for the parental punishment style questionnaire. A sample of 1028 junior high school students were asked to complete the questionnaire and 158 of them was given retest after a month. Results: Taken from the questionnaire by exploratory factor analysis four factors were compatible. The results of confirmatory factor analysis showed a good fit to the data. The internal consistency reliability of father and mother questionnaire was satisfactory, with Cronbach ? coefficient 0.91; and the test-retest reliability was also satisfactory, with test-retest correlation coefficient 0.88 and 0.89, which showed good content validity and high construct validity. Conclusion: The questionnaire has good reliability and validity, and meets the need of psychometrics.

Objective To investigate the relationship between ultrasonographic features of papillary thy-roid carcinoma(PTC)and lateral cervical lymph node metastasis (LCLNM).Methods A total of 449 eligible ca-ses with 633 PTC nodules was selected and divided into two groups:LCLNM group included 135 nodules(91 pa-tients);Without metastatic groups included 498 nodules(135 patients).Ultrasonographic features of PTC nodules and the relationship with LCLNM were analyzed by χ2 test and logistic regression analysis .Results In univariate analysis,the significant factors were male,age<45yrs,multifocal,maximal diameter(d>1 cm),multi-microcal-cificaltion(d<2 mm),mixed flow,wider than tall,CCLNM,extrathyroid extension,located in upper(P<0.05 or P<0.017).Multivariate analysis showed that multi -microcalcificaltion(d<2 mm),wider than tall,CCLNM,ex-trathyroid extension,located in upper pole were predictive factors of LCLNM (P<0.005,OR=1.626,2.644, 0.479,2.579).Conclusion High-frequency ultrasound can accurately describe the sonographic appearance of thyroid nodules;it can be used to remind the risk of LCLNM before operation ,and will be informative for the treat-ment of surgery .
