Objective: To establish an HPLC method for the determination of three bacteriostatic agents ( methylparaben, eth-ylparaben, propylparaben) in taurine eye drops. Methods:The HPLC method was conducted on a Phenomenex Gemini C18 column ( 250 mm × 4. 6 mm, 5 μm ). The mobile phase was 1% acetic acid-methanol(40 :60). The flow rate was 1. 0 ml·min-1 and the de-tection wavelength was 254 nm with the injection volume of 20 μl and the column temperature of 25℃. Results:Methylparaben, eth-ylparaben and propylparaben showed good linear relationship (r>0. 999)within the range of 1. 00-19. 94μg·ml-1,2. 01-20. 08μg· ml-1 and 0. 21-10. 46 μg·ml-1,respectively. The average recoveries were 99. 20%-99. 90%, and the RSDs were 1. 34%-1. 54%(n=9). Conclusion:The method is accurate, reproducible and stable without interference, which can be used for the determination of three bacteriostatic agents in taurine eye drops.

Objective Patients in the intensive care unit (ICU) are at high risk for multi-organ failure and death. Few well-established scoring systems have been used in the cardiac surgery. We try to identify a feasible score system for the risk assessment after CABG. Methods 1028 consecutive patients who had received CABG and staying in a single cardiac postoperative intensive care unit of Anzhen hospital were enrolled in the prospective study between October of 2007 and May of 2008 and assessed daily with three score systems, the multiple organ dysfunction score (MODS), the sequential organ failure assessment (SOFA) and our postoperative score for cardiac surgery (PSCS). Four new variances were added to PSCS system, which were Euroscore, IABP, ECMO and dialysis. Euroscore was considered as a preoperative factor which provided the preoperative information of the patient. IABP and ECMO were considered as assistant factors to support circulatory system. The dialysis was also considered as an assistant factor to support renal system. The differences with the respects of sensitivity and specificity among the three systems were compared with Hosmer-Lemeshow goodness-of-fit and receiver operating characteristic (ROC)curve. Results The new variances added to PSCS system were shown to be associated with mortality in a multivariate logistic regression analysis. The EXP(B) value for Euroscore was 3. 803, the EXP(B) value for IABP was 1. 645, the EXP(B) value for ECMO was 3.803, and the EXP(B) value for dialysis was 1.605. In discrimination analysis, ROC values of the operative day score were 0.602 for MODS, 0.571 for SOFA, and 0. 821 for PSCS; ROC values of the maximum score were 0.847 for MODS, 0.830 for SOFA, and 0.929 for PSCS; ROC values of the maximum score during the first 3 days were 0.838 for MODS, 0.814 for SOFA, and 0.919 for PSCS; score changes of ROC value between the third day and the first day were 0.767 for MODS, 0.779 for SOFA, and 0. 780 for PSCS. In calibration analysis, we compared the x2 values, P values and overall corrected percentage of the three different systems. x2 values of the three systems were 6. 763 for MODS, 4. 101 for SOFA, and 1.687 for PSCS; P values of the three systems were 0.454 for MODS, 0. 848 for SOFA, and 0. 975 for PSCS; overall corrected percentages of the three systems were 98.1%, 98%, and 98.3% respectively. Conclusion The sensitivity and specificity of PSCS were superior to MODS and SOFA in predicting death risk after CABG.

Background and purpose:MiR-224 is overexpressed in hepatocellular carcinoma, and participate in invasion and metastasis of cancer. The aim of this study was to investigate the effects of miR-224 antisense oligonucleotide (ASO) on the proliferation and apoptosis of Hep3B cells.Methods:After transfection with miR-224 ASO, and detecting the miR-224 mRNA expression of Hep3B cells by real-time quantitative PCR; the miR-224 expression in Hep3B cells was measured and cell proliferation was analyzed by MTT assay and the colony formation experimentin vitro andin vivo. The cell apoptosis was analyzed by flow cytometry.Results:Compared with the control group, miR-224 ASO significantly reduced the miR-224 mRNA expression in the Hep3B cell(P<0.05), MTT assay results showed that Hep3B cells survived rate decreased greatly after transfection with miR-224 ASO. Clone formation assay revealed that the colony formation rate in miR-224 ASO group was significantly lower than that in the control group.In vivo study further confirmed that miR-224 ASO could inhibit the proliferation of Hep3B cells,and miR-224 ASO group grew substantially slow compared with the negative control. Flow cytometry indicated that miR-224 ASO group promoted apoptosis significantly.Conclusion:miR-224 was overexpressed in Hep3B cells. Reducing the expression of miR-224 can effectively inhibit the growth of Hep3B cells and promote apoptosis. miR-224 may become a new target for the regulation of gene expression in hepatocellular carcinoma.

Objective To study the frequency of the derivative chromosome 9 [der(9)] deletion among patients with chronic myeloid leukemia (CML), and explore the application value of local-specific inspector (LSI) 9q34 probe in detect the der (9) deletion. Methods Cytogenetic analysis was performed by 24 h unstimulated culture, GTG banding and karyotype. Dual colour/dual fusion or extra signal(ES) DNA probe was used to perform interphase-FISH for the detection of bcr-abl fusion gene in 52 patients with CML. LSI 9q34 DNA probe was used to detect der(9) deletion. Results FISH results showed bcr-abl fusion gene existed in all 52 patients with CML. der(9) deletion was detected in 12 patients with ES/DCDF probe, but only in 11 patients with LSI 9q34 probe. Conclusion It's more efficient in detection of der(9) deletion with LSI 9q34 probe. Deletion of der(9) might be a poor prognostic factor for CML patients, and LSI 9q34 probe should be used in all the CML patients with positive bcr-abl fusion gene.

Objective To investigate the effects of astragalus polysaccharides(APS)on the metabolism of collagen in hamsters with diabetes mellitus(DM) and explore the possible mechanism of APS on diabetic cardiomyopathy. Methods The levels of insulin,C-peptide,myocardial enzymes,glycosylated serum protein(GSP),plasma and myocardial angiotensin(AngⅡ) were tested in APS group(n=15) and DM control group(n=15).Immunohistochemistry was used to measure the expression levels of typeⅠand typeⅢ collagen,activities of matrix metalloproteinases(MMPs) were examined by using zymography,and TNF-? and TGF-? mRNA were detected by RT-PCR. Results Compared with DM control group,levels of GSP,myocardial enzymes and myocardial AngⅡ were much lower in APS group(P0.05).The level of expression of collagen Ⅰ,the ratio of collagen Ⅰ/collagen Ⅲ,and the activity of pro-MMP-2 and MMP-2 in APS group were significantly lower than those in the DM group(P
