Objective To evaluate the relationship between combined muhigene detection and response to chemotherapy and prognosis in epithelial ovarian carcinomas(EOCS).Methods A total of 80 ovarian tissue samples taken from the surgical specimens of patients with EOCS of our hospital in the last two decades who had received chemotherapy "after surgery were paraffin-embedded.The samples were divided into 2 groups,good prognosis group(patients who survived more than 2 years,n=46)and poor prognosis group(patients who survived less than 2 years,n=34).The expression levels of ToPo-Ⅱ,Ki-67,MGMT, PCNA,p27,p53,pl6,P-gp,LRP,GST-?,bcl-2,C-myc,Fas,bax,MSH2,MRP and BCRP were investigated by the combination of tissue arrays and immunohistoehemical streptavidin-biotin peroxidase(SP) method in all samples.Data were analysed with SPSS 12.0 for windows.Results There were statistically significant differences in the positive expression levels of P-gp,BCRP,MGMT,MSH2,p27 and p16(62%, 50% and 50% in poor prognosis group vs 33%,28% and 28% respectively,P

Objective To study the significance of the sample S/Co ratio when using a domestic reagent for anti-hepatitis C virus(HCV)antibody detection and to explore the procedure and standard of anti-HCV antibody diagnosis by using this domestic reagent.Methods Anti-HCV antibody was detected in 295 000 blood donors by a domestic anti-HCV reagent with enzyme-linked immunosorbent assay(ELISA)method and the reactive samples were tested again by ortho anti-HCV antibody reagent.The samples which anti-HCV antibodies were determined as positive by ortho anti-HCV rea- gent were examined by recombinant immunoblot assay(RIBA)reagent and 106 samples of them were also tested for HCV RNA.Results Six hundred and eighty-one samples were reactive in 295 000 samples screened by the domestic ELISA reagent,the reactive ratio was 0.23 %.Among the reactive samples screened by the domestic ELISA reagent,367 samples were determined as positive by ortho anti-HCV reagent while 66.2% of them showed a S/Co ratio≥3.8.The consistency rate between positive results determined by the domestic reagent and RIBA reagent respectively was 53.8%.For the samples showing S/Co ratio≥3.8 by ortho anti-HCV reagent,94.2% had a S/Co ratio≥8.0 when using the domestic ELISA reagent,while the percentage of samples showing S/Co ratio

OBJECTIVETo study the relationship between TMPRSS2: ERG gene fusion and the pathological grade of prostate cancer (PCa).

METHODSWe collected fresh prostatic tissue samples from 62 patients with PCa and another 10 with benign prostatic hyperplasia ( BPH) and included 9 cancer cell strains as the control. We examined the TMPRSS2:ERG fusion gene in the PCa samples by nest RT-PCR, compared the Gleason scores between the TMPRSS2:ERG-positive and -negative cases, and analyzed the association of TMPRSS2: ERG fusion with the pathological features of PCa.

RESULTSThe TMPRSS2: ERG fusion gene was detected in 28 (45.16%) of the PCa cases, but in none of the 10 BPH cases or the 9 cancer cell strains. No statistically significant differences were found in the Gleason scores between the TMPRSS2:ERG-positive and -negative cases (Z = -0.609, P = 0.542), but the primary Gleason score was markedly higher in the former than in the latter (Z = -2.600, P = 0.009). Univariate logistic regression analysis showed that TMPRSS2:ERG was associated with the cribriform growth pattern (OR = 6.250, P = 0.002), foamy gland morphology (OR = 6.666, P = 0.023), and signet-ring cells (OR = 3.240, P = 0.035), but multivariate logistic regression analysis manifested that it was associated with the cribriform growth pattern only (OR = 3.750, P = 0.033).

CONCLUSIONTMPRSS2:ERG gene fusion was associated with higher pathological grades of prostate cancer.

Traditional Chinese ancient prescriptions have been used for treatment of liver cancer for a long history and the scientific and rational compatibility is a great wealth for modern research and development (R&D) of new drugs. The research and development of new drugs are often accompanied with a large investment, a long cycle and a high risk, especially for the anti-tumor drugs R&D which are facing more risks and lower successful rate. In this research, the regularity of compatibility of drugs was analyzed from 124 anti-hepatoma ancient prescriptions by computer program. The results can offer help to the R&D of anti-hepatoma new drugs and reduce the risk of drug screening. In addition, we surveyed 22 companies in this field from six provinces such as Beijing, Shanghai, Tianjin and so on and obtained 240 risk assessment questionaires. Then we used qualitative analysis method to interpret the greatest impacts for the risks in the process of R&D, production and sales of anti-hepatoma new drugs. The study provides a basis for anti-liver cancer drugs R&D researchers, who can take effective measures to reduce the R&D risks and improve successful rate.
