Objective To investigate the genotype of HPV and L1 gene polymorphism of HPV subtype 6b in patients with condyloma acuminatum (CA) from Wenzhou region. Methods Gene chips were used to profile the genotype of HPV in tissue samples from 73 patients with CA. PCR was performed to amplify the L1 gene in 11 samples positive for HPV type 6 followed by sequencing. Results Of the 73 patients, 61 (83.56%) were positive for HPV DNA. Among the 61 HPV-positive patients, 93.44% were infected with single type of HPV, and 6.56% with mixed type of HPV. In patients infected with single type of HPV, type 11 predominated with a prevalence of 29.51% followed by HPV 6 (18.03%); in those infected with mixed type of HPV, 6and 11 were the most common genotypes. Besides, sequencing analysis revealed single nucleotide polymorphism at 6 sites of HPV 6b type L1 gene, and an A/T polymorphism at position -810 was present in all samples, which was considered to be a local mutation of HPV from Wenzhou region. Conclusions In Wenzhou region, HPV types 11 and 6 prevail in patients with CA, and multiple mutations are present in L1 gene of HPV 6b type.

Objective This study was aimed to investigate the methodology of radiofrequency ablation for paroxysmal atrial fibrillation (PAF) in complicated cases Methods 130 cases (87 males) with the average age of 56 years were enrolled consecutively Each patient was diagnosed PAF by Holter and ECG After routine transseptal procedure and cannulation, retrograde pulmonary venography was taken to show the anatomic morphology of all pulmonary veins (PVs) Under the guidance of Lasso circular mapping catheter, all cases underwent electrical isolation for four PVs using the saline irrigated ablation catheter Results (1) By venography,21 PVs (16 2%) were found to have enormously dilated ostia in 21 out of 130 cases 5 PVs (3 8%) had left common trunks 3 PVs (2 3%) had right common trunks In 6 cases right PVs were found to have multiple bifurcated ostia, and the prevalence rate was 4 7% (2) A total of 341 PVs were targeted for segmental ablation in 130 cases Complete isolation was failed in 29 PVs, including 11 PVs with dilated ostia Among the 29 PVs, 14 were left superior PVs (LSPVs), 8 were left inferior PVs (LIPVs), 5 were right inferior PVs (RIPVs), and 2 were right superior PVs (RSPVs) Conclusion The anatomical variants of PV was the main cause of complicating radiofrequency ablation in patients with PAF

Objective To evaluate the potential association of CD4+CD25+ T cells with alopecia areata.Methods Totally,this study enrolled 23 patients with progressive alopecia areata,25 patients with stable alopecia areata,and 25 healthy controls.Peripheral blood was isolated from these subjects followed by isolation of CD4+ CD25+ regulatory T cells,which were then cuhured with the presence of anti-CD3 and-CD28 monoclonal antibodies for four days.Subsequently,enzyme-linked immunosorbent assay was performed to measure the levels of interleukin (IL)-10 and transforming growth factor (TGF)-β1 in the culture supematant of these T cells.Results The levels of IL-10 and TGF-β1 were (31.68 ± 6.78) pg/ml and (32.29 ± 6.8) pg/ml respectively in the culture supernatant of CD4+CD25+ regulatory T cells from patients with progressive alopecia areata,significantly lower than those from the healthy controls ((57.34 ± 14.15) pg/ml and (57.43 ± 15.16) pg/ml,both P ＜ 0.05) and patients with stable alopecia areata ((52.56 ± 13.02) pg/ml and (61.75 ± 14.10) pg/ml,both P ＜ 0.05).However,no significant difference was observed in the supernatant levels of IL-10 or TGF-β1 between the healthy controls and patients with stable alopecia areata.Conclusions The secretion of IL-10 and TGF-β1 by CD4+CD25+ T cells is decreased in patients with progressive alopecia areata,which may contribute to the pathogenesis of alopecia areata.
