Objective To investigate the relationship between subclinical cervical HPV infection and recurrence of condyloma acuminatum (CA) in patients. Methods Cervical swabs were collected from 52 patients with frequently recurrent CA, 55 patients with infrequently recurrent CA, and 65 normal human controls. The Cenechip method was performed to detect the presence and type of HPV in cervical swabs followed by a statistical analysis. Results HPV was found in 67.3% (35/52) of swabs from patients with frequently recurrent CA, 5% (19/55) from patients with infrequently recurrent CA, and 4.6% (3/65) in the controls. There was a statistical difference among the three groups in the detection rate of HPV. Conclusion The subclinical cervical HPV infection may contribute to the recurrence of CA.

Objective To investigate the effects of interleukin-17 (IL-17) on the cell proliferation, apoptosis and migration of human laryngeal carcinoma Hep-2 cells.Methods IL-17 was transiently transfected into Hep-2 cells, and at the same time empty vector group (pEGFP-N1) and normal control group were set up.The efficiency of transfection was evaluated by fluorescence microscope, and the mRNA and protein expressions of IL-17 were detected by reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting.The proliferation of cells was detected by methyl thiazolyl tetrazolium (MTT) method, and the apoptosis was detected by flow cytometry.The migration ability was detected by wound-healing assay and Transwell assay.ResultsHep-2 cells transfected with empty vector pEGFP-N1 and IL-17 showed green fluorescence under the fluorescence microscope.Hep-2 cells expressed IL-17 at both mRNA and protein levels after transfection with IL-17.Compared with the normal control group, the proliferation of IL-17 transfected Hep-2 cells was significantly inhibited after 48 h transfection (0.34±0.03 vs.0.46±0.04, P=0.006).The apoptotic rate of IL-17 transfected cells was higher than that of normal control group (26.80%±0.80% vs.2.90%±0.31%, P=0.000).According to the wound-healing assay, compared with the normal control group, the scratch width of IL-17 transfected cells was significantly greater (1.59±0.01 vs.1.36±0.01, P=0.000).Transwell migration experiment showed that the migration of IL-17 transfected cells was significantly lower than that of the normal control group (26.33±2.08 vs.49.33±1.53, P=0.000).Conclusion IL-17 can inhibit the proliferation of human laryngeal carcinoma Hep-2 cells, reduce their migration ability and enhance their apoptosis ability.Therefore, IL-17 may inhibit the occurrence and development of laryngeal carcinoma through a variety of mechanisms.
