Objective To observe the levels of Foxp3+ CD+ CD25+ regulatory T cells in the peripheral blood of condyloma acuminatum (CA) patients and investigate their roles in the pathogenesis of CA. Methods The peripheral blood was collected from 30 CA patients (including 15 with relapsing and 15 with first onset) and 20 healthy controls. Peripheral blood mononuclear ceils (PBMC) were isolated and stained with anti-human CD4-PE-Cy5 and anti-human CD25-fluorescein isothiocyanate (FITC) monoclonal antibodies on cell membrane, followed by intraeellular staining with anti-human Foxp3-PE. The percentage of Foxp3+ CD4+-CD25+ regulatory T cells was detected by three-color flow cytometry. Comparison between groups was done by ANOVA test. Results The percentages of Foxp3+ CD4+ CD25+ regulatory T cells among total CD4 + T cells in CA patients and relapsing CA group were (3.4 ± 1.0) % and (4.7 ±+ 1.2) %, respectively, which were both significantly higher than that in healthy control group [(1.2±0. 5)%, P<0.01]. Furthermore, that in first onset CA group was (2. 1 ± 1.0) %, which was higher than that in healthy control group, but without statistical significance; but that in relapsing CA group was significantly higher than that in first onset group (P<0.05). Conclusions The number of Foxp3+ CD4+ CD25+ regulatory T cells increases in the peripheral blood of CA patients. The disorder of cellular immunity may be involved in the immunopathogenesis of CA.

Aim To screen the differentially expressed microRNAs ( miRNAs ) induced by hypoxia precondi-tioning ( HPC ) in adult rat cardiomyocytes, and pre-dict miRNAs-regulated target genes and their func-tions. Methods Cardiomyocytes were isolated from a-dult rat ventricular myocardium and cultured ( in vitro) . The cells were divided into 2 groups: control group ( CON ) and hypoxia preconditioning group ( HPC) . The cardiomyocytes in HPC group were sub-jected to 10 min hypoxia followed by 30 min reoxygen-ation, while the cells in CON group were cultured un-der normal condition. After that, total RNA was ex-tracted and then subjected to miRNA microarray to screen differentially expressed miRNAs. The microar-ray results were further validated by quantitative RT-PCR ( qRT-PCR ) . Bioinformatics analysis was per-formed to predict the miRNAs-regulated target genes and analyze the enriched gene ontology ( GO) and sig-naling pathway ( Pathway) . Results HPC caused sig-nificant changes in miRNAs expression in cardiomyo-cytes as compared to CON group. A total of 12 miR-NAs were up-regulated and 14 miRNAs were down-reg-ulated ( P <0. 01 , FDR <0 . 05 ) . The differentially expressed 7 miRNAs with a fluorescent signal intensity>500 were selected for further bioinformatics analysis. The expression of miR-133b-5p, miR-664-1-5p and miR-6216 detected by qRT-PCR exhibited the similar patterns of up or down regulation to those shown in mi-croarray results. Bioinformatics analysis revealed that miRNAs-regulated target genes were significantly en-riched in 27 GOs and 6 signal pathways. Conclusion
The expression profile of miRNAs in rat cardiomyo-cytes is significantly affected by HPC. These differenti-ally expressed miRNAs might participate in HPC-in-duced cardioprotection by regulating their target genes in rat cardiomyocytes.
