Interventions
Wart injection (0.2 mL \<5 mm; 0.5 mL 5-10 mm; 1ml for \>10 mm) were injected at a depth of 1.5mm, diluted with normal saline at a concentration of 3u/ml=3mg/ml, and the maximum amount of each wart was 1ml until the wart turned white
The wart was frozen by liquid nitrogen until a circle of frozen tissue appeared around the wart for about 10s, with an interval of 30s, for a total of 2 times
