The aim of this study is to investigate the apoptotic inhibition and its molecular mechanism of dexamethasone (DEX) acting on cisplatin (CDDP)-induced apoptosis of human lung adenocarcinoma cell SPC-A1; SPC-A1 cells were pre-cultured in vitro for 24 hours with DEX in different concentrations and then CDDP was added in different concentrations for culturing for further 48 hours. The survival rates of the cells were determined by MTT. The expression of serum/glucocorticoid-induced kinase (SGK-1) and mitogen-activated protein kinase phosphatase-1 (MKP-1) in SPC-A1 cells after being cultured by 1 micromol/l DEX at different time was detected by semi-quantitative RT-PCR technology. The expression of glucocorticoid receptor (GR) in SPC-A1 cells was measured by immunohistochemistry (IHC) with biotin-labeled anti-GR. The results of MTT showed that SPC-A1 cells had resistance to CDDP-induced apoptosis with pre-cultured DEX and the resistance intensity presented DEX concentration-dependent. The expressing quantity of SGK-1 in SPC-A1 cells stimulated by DEX could be elevated and increased with intention of time, but the express of MKP-1 was not detected. Up-regulated expression of GR in SPC-A1 cells stimulated by DEX was detected by IHC. The number of cells expressing GR in SPC-A1 cells was significantly higher than that in the control group. The results showed that DEX inhibited apoptosis of SPC-A1 cells induced by CDDP. The possible molecular mechanism is that elevated expression of GR induced by DEX up-regulates the expression of SGK-1 which locates at the downstream of anti-apoptosis pathway. The apoptosis resistance of SPC-A1 cells may account for all above the factors.

AIM: The effective antisense sequences targeted VEGF mRNA with computer software would be screened and designed, and effect of them on growth K562 cells and protein expression of VEGF were studied with experiments. METHODS: Seven antisense sequences were selected and synthesized, which consisted of 18-20 deoxynucleotide acid and were modified with phosphorothioate, according to principle of low free energy of overall △G 37 Overall. Cell growth was assayed by trypan blue dye exclusion assay and level of VEGF protien in the media was determined by ELISA. RESULTS: Six of seven sequences were capable of inhibing growth of K562 cells and downregulating the VEGF protein expression significantly, compared with Scrambed control group. It was found that there was a close correlation between low level of overall △G 37 and antisense effectiveness ( r =0 887, P

OBJECTIVE:To evaluate the present situation and trend of the antidepressants.METHODS:The antidepres?sants drugs in21hospitals of Hangzhou during2000～2003was statistically analyzed with respect to sales sum,market struc?ture etc.RESULTS:The total amount for antidepressants increased dramatically year by year.The consumption of the im?ported antidepressants has been decreasing while that of the domestic has been increasing and that of the antidepressants from the joint ventures remained stable.CONCLUSION:There is a great potential for the development of antidepressants;the sales amount and the consumption sum take on a trend of increasing rapidly.

Bone marrow cell morphology is a difficult point in laboratory diagnostics teaching.Computer-aided instruction(CAI) teaching documents were made according to the teaching outlines of laboratory diagnostics.The CAI teaching documents,which represent distinct cellular features of different types of bone marrow cells,were applied in normal and hematological diseases of bone marrow cell morphology teaching,combined with proper teaching methods.It proved to be a useful teaching style in improving teaching and learning efficiency in laboratory diagnostics.

Through the literature combing the interest groups of hospital information disclosure in the United States, the demand and practice of the main interest groups are analyzed. This paper uses policy maker4. 0 software to further analyze the interests of various interest groups, power and the degree of influence by the policy of hospital information disclosure. The results showed that interest groups involved in hospital information disclosure in the Unit-ed States can be mainly divided into five categories:consumers, employers, health insurance companies, hospitals, and decision makers ( government) . In order to balance the cost-effectiveness of various insurance schemes, health insurance companies choose high-quality service providers to restrict poor-service providers and insurers, and hospi-tals need to use public information to manage and improve health care. In order to monitor and improve the quality of medical services, employers need to weigh various insurance plans, health insurance companies have to measure the service quality of themselves and competitors, and hospitals need to manage and improve the medical quality and in-crease market share. As the largest stake in the hospital information disclosure, the results show that the consumer's position on the hospital information disclosure is low support. From the consumer as a main, although the hospital in-formation disclosure practices but the right to speak and other small powers have a limited participation. Analyzing the of the interest groups of hospital information disclosure in the United States, they all push forward the hospital infor-mation disclosure work to provide evidence to support.

Objective: To exploration the self-efficacy, self-esteem, and positive/negative affect and the re-lationships among them in Chinese adolescents. Methods: The Rosenberg's Self-Esteem Scale, Generalized Self-Ef-ficacy Scale, and Adolescents Positive/Negative Affect Scale were administrated to 2247 middle school students sampled from 16 schools from 6 districts. Results: Self-esteem tended to increase as grade [(2.91±0.38), (2.93±0.41), (3.01±0.41), (2.98±0.44), (3.04±0.41), (3.17±0.42)]. Boys had higher self-efficacy [(2.74±0.39)vs.(2.68±0.40), P <0.001]. Two senior grades had higher self-efficacy than other 4 grades (P<0.05). Girls had higher positive and negative affect [(2.77±0.67)vs.(2.68±0.67), (2.22±0.70) vs.(2.13±0.68), Ps <0.05]. Junior grade one had the highest positive effect (2.85±0.62), grade one and two in high school had more negative effect than other 4 grades (2.26±0.71, 2.25±0.73).Self-efficacy and self-esteem were positively correlated with positive affect (r=0.24, 0.36), negatively correlated with negative af-fect (r=-0.17, -0.32) ; self-esteem significantly mediated the relationship between self-efficacy and positive/negative affect (Z=13.00, -13.07) . Conclusion: Self-esteem tends to increase as grade, boys have higher self-efficacy than girls, and girls have higher positive and negative affect than boys. Self-esteem mediates the rela-tionship between generalized self-efficacy and positive/negative affect in Chinese adolescents after controlling the effects of gender and grade.
