为了明确ＣＯ２激光治疗尖锐湿疣过程中，烟尘中是否有ＨＰＶ存在，采用ＰＣＲ方法对尖锐湿疣患者治疗时烟尘标本和组织块标本进行ＨＰＶ６和１１型ＤＮＡ检测。结果：２１例组织块中，１９例阳性；从距激光烧灼部位５ｃｍ（２１例）和５０ｃｍ（１２例）处收集的烟尘标本中，无１例阳性。实验中未发现烟尘中及不同的吸附材料（无纺布、纱布和擦镜纸）存在对ＨＰＶ检测有抑制作用的物质。本实验的结果提示：在用大功率ＣＯ２激光治疗疣时，其烟尘中无ＨＰＶ，不会对周围人群造成危害。
In order to clarify the presence of HPV in smoke and dust during the CO2 laser treatment of condylomata acuminata, HPV6 and 11 DNA were detected by PCR in the samples of soot and tissue of patients with condyloma acuminatum. RESULTS: Of the 21 tissue masses, 19 were positive; none of the smear samples collected at 5 cm (21) and 50 cm (12) locations from the laser ablation site were positive. In the experiment, it was not found in the soot and different adsorbent materials (non-woven fabrics, gauze and lens paper) there is a substance that has an inhibitory effect on the HPV test. The results of this experiment suggest that when using high-power CO2 laser treatment of warts, no dust in the HPV, will not cause harm to the surrounding population.
