Objective:To investigate the inhibitory effect of RXRγ and RARβ on the growth of human gastric carcinoma cell line SGC7901 treated by RXR agonist(9-cis-RA). Methods:The human gastric carcinoma cell line SGC7901 was treated with 9-cis-RA, and then the morphological changes were observed by H-E staining. The cell growth was detected by MTT assay. The apoptosis and the cell cycle progression were analyzed by flow cytometry. The expressions of RXRγ and RARβ were detected by immunocytochemistry staining and western-blot assay. Results: HE stain showed that the SGC7901 cells were sparser with the increasing concentration of 9-cis-RA. The growth of SGC7901 cell was inhibited by 9-cis-RA at the concentration of 20 μmol/L in time and dose depended manner. The apoptotic rate of the tumor cells increased after 72 hours at the concentration of 20 μmol/L 9-cis-RA and the tumor cells were arrested in G0/G1 phase. Immunocytochemistry and Western-blot assay showed that the expressions of RXRγ and RARβ increased after 72 hours, compared with those of negative control group. Conclusion: RXR agonist 9-cis-RA can inhibit the growth of SGC7901 cells via inducing cell apoptosis through upgrading the expressions of RXRγ and RARβ.

Objective:To investigate the occurrence of antenatal anxiety and possible influencing factors,and analyze its relationship with spontaneous delivery.Methods: 590 healthy puerperal women who delivered in Taihe hospital during Dec 2007 and Dec 2008 were randomly selected and investigated for their psychological status,with T-A1 anxiety scale and SDS depression scale employed.Results: 569 effective questionnaires were gathered,with 114 cases divided into the anxiety group and 159 cases into the depression group.Influencing factors of antenatal anxiety include fear of delivery,worry about the safety of babies,understanding of delivery knowledge,puerperal age,and the family financial status.Conclusion: Factors including a relatively older age of primipara,poor financial status,insufficient support from family,worry about the safety of oneself and baby,and fear for delivery pain all have close connections with antenatal mental disorders.Meanwhile,antenatal mental disorders have a direct influence on delivery quality and the choice of delivery modes,and increase the failure rate of spontaneous delivery.

Objective To discuss the application of Occupational Functioning Model (OFM) in occupational therapy teaching. Methods The students in grade 2009 and 2010 for their course of Occupational Therapy Clinical Application were included. The former were taught in routine way, and the latter were taught with OFM. They were investigated with questionnaires of satisfaction of course and teaching. Results There were 94.1% of the students felt beneficial in the clinical thinking, 86.3% in the comprehensive quality. There was more in the grade 2010 than 2009 of students reported to be benefited in such as guidance of the occupation mode for the clinical practice, independent thinking, clinical thinking, and the capability of evaluation and plan of systemic rehabilitation (P<0.05). Conclusion OFM may help students to understand occupational therapy deeply, develop the clinical thinking, and improve the comprehensive quality.

OBJECTIVE: To investigate the value of each single and combined applications of ultrasound thyroid imaging reporting and data system (TI-RADS), ultrasonic shear wave elastography in the diagnosis of thyroid microcarcinoma (TMC). METHOD: 323 patients with thyroid tiny nodules confirmed by surgery and pathology were analyzed prospectively. Then their TI-RADS and shear wave elastography features were summarized. SWE elasticity indices (mean, minimum and maximum value of interest) of nodules were measured. The surgical pathology results were regarded as the gold standard to calculate the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of TI-RADS, shear wave elastography and their combination in the diagnosis of TMC. The receiver operating characteristic (ROC) curve of TI-RADS, shear wave elastography and combined application of both were drawn. The area under the ROC curve were calculated. Furthermore, the value of combined application of both examinations in the diagnosis of thyroid microcarcinoma (TMC) was investigated. RESULT: From 323 nodules,253 were thyroid carcinomas and 70 were benign. Areas under the ROC curves (AUC) of SWE parameters were 0. 648,0. 629 and 0. 605. For SWE, the optimal cut-off value according to ROC curve was SWE_max = 65.50 kPa and SWE_mean = 37.50 kPa. Generally, the sensitivity, specificity, accuracy, PPV and NPV were 88.14%, 82.86%, 87.00%, 94.89% and 65.91% for TI-RADS, and 49.01%, 74.29%, 54.49%, 87.32% and 28. 73% for SWE. There were statistically significant differences in the sensitivity, accuracy, PPV and no statistically significant differences in the specificity, and NPV. The sensitivity,specificity, accuracy, PPV and NPV were 95.26%, 67.14%, 89.16%, 91.29% and 79.66% for combined application of both. The area under the ROC curve of TI-RADS, shear wave elastography and their combination were 0.763, 0.616, 0.804. For nodules ≤ 5 mm, the sensitivity, specificity, accuracy, PPV and NPV were 91.67%, 66.67%, 87.07%, 92.44% and 64.29%. However, for nodules 5-10 mm,the sensitivity,specificity, accuracy, PPV and NPV were 98.50%, 67.44%, 90.91%, 90.34% and 93.55%. CONCLUSION The diagnose of TMC can be further improved by combined application of ultra-sonic TI-RADS and SWE.
