ObjectiveTo inyestigate the effect of miRNA-155 expression on the differentiations and functions of CD4 + T lymphocyte in patients with unstable angina pectoris. MethodsTwenty-one patients with unstable angina pectoris (UAP) were enrolled in this study, and another 18 patients with normal coronary arteries evidenced by angiography were assigned as control group. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expression of miRNA-155 in CD4 + T lymphocyte of the peripheral blood. And the levels of IFN-γ and IL-4 in serum were determined by using enzyme-linked immunosorbent assay (ELISA). The CD4 + T lymphocyte were isolated from mononuclear cells prepared with Ficoll-Hypaque density-gradients centrifugation from human peripheral blood by magnetic cell sorting system. Then, the CD4 +T cells (2 × 106 cells/mL) were seeded in culture plates with 6 wells.The CD4 + T lymphocytes were divided into 3 groups in experiment: control group, miRNA-155 group, and miRNA-155 inhibitor group. The numbers of Th1 and Th2 cells were measured by flow cytometry analysis (FACS).The protein levels and expressions of IFN-γRα, T-bet, GATA-3 mRNA were measured by using western blotting and qRT-PCR, respectively. The levels of IFN-γ and IL-4 in culture supernatants of CD4 +T lymphocytes were detected by using ELISA. ResultsIn comparison with the control group, there was significant increase in the expression of miRNA-155 and serum level of IFN-γ in the UAP group (P <0. 01 ). There was a positive correlation between miRNA-155 and serum IFN-γ ( r =0. 842, P < 0. 0l ).However, in vitro, the number of Th1, the protein level and expression of T-bet mRNA, and supernatant IFN-γ increased, and the protein level and expression of IFN-γRα protein decreased in miRNA-155 group in comparison with the control group (all P <0. 01 ). Interestingly, there were no significant differences in the number of Th2 cells, the expressions of GATA-3mRNA and IFN-γRα mRNA, GATA-3 protein and supernatant IL-4 between control group and miRNA-155 group ( all P > 0. 05 ). And the miRNA-155 inhibitor could attenuate the effect of miRNA-155 effectively. ConclusionsThe miRNA-155 can promote differentiations and improve the function of Thl, playing an important role in the pathogenesis of unstable angina pectoris.

Objective To explore the clinical therapeutic efficacy and value of endovascular embolization treatment for Hunt-Hess poor-grade intracranial aneurysms. Methods Eighty-seven patients with Hunt-Hess grade Ⅳ - Ⅴ intracranial aneurysrns were treated with endovascular embolization from May 2001 to February 2010,77 patients were grade Ⅳ and 10 patients were grade Ⅴ. Outcomes were assessed by using the Glasgow outcome scale (GOS). Results Follow-up time was from 3 months to 9 years. The therapeutic efficacy was as following according to GOS: 25 patients were grade Ⅰ , 5 patients were grade Ⅱ , 9 patients were grade Ⅲ , 12 patients were grade Ⅳ ,and 36 patients were grade Ⅴ. There were 55.17%(48/87) favorable outcome rate and 28.74% (25/87) mortality rate in all patients. There were 61.70%(29/47) favorable outcome rate and 25.53%(12/47) mortality rate in early stage treatment patients (diseased within 3 d), otherwise there were 47.50% (19/40) favorable outcome rate and 32.50%(13/40) mortality rate in medium and late stage treatment patients (diseased 3 d or later). There were no statistically significance in favorable outcome rate and mortality rate between them (P > 0.05). All the patients were embolized successfully ,technical complications occurred in 8 patients, 10 patients were found angiographic evidence of vasospasm. Conclusions Endovascular embolization is an effective method for treating Hunt-Hess poorgrade intracranial aneurysms. Early stage treatment is a feasible option because it can improve prognosis by reducing rebleeding and vasospasm.

Objective To investigate the relationship between the methylation of CpG island of RUNX3 gene promoter and its expression in a human cutaneous malignant melanoma cell line A375, and to assess the role of RUNX3 gene methylation in the pathogenesis of human cutaneous malignant melanoma. Methods Cultured A375 cells were treated with various concentrations (0, 1, 5, 10, 20 μmol/l) of 5-azacyti-dine for 24 or 72 hours followed by another 5 days of culture. Then, methylation-specific PCR (MSP) was performed to evaluate the methylation status of RUNX3 promoter region, and Western-blot analysis to detect the protein expression of RUNX3 in A375 cells. Results The RUNX3 gene promoter region was hypermethylated in untreated A375 cells, along with the absence of protein expression of RUNX3. However, after the treatment with 5-azacytidine, the promoter region of RUNX3 gene was demethylated partly, and the expression of RUNX3 protein was restored in A375 cells. Further, the expression intensity was directly correlated with the concentration of 5-azacytidine. Conclusions The promoter hypermethylation of RUNX3 gene may be related to the silencing of RUNX3 gene expression in A375 cells, whereas 5-azacytidine can cause the demethylation of RUNX3 gene, reactivate the gene which has been inactivated by the promoter hypermethylation, and finally induce the re-expression of RUNX3 protein.
