ABSTRACT

Objective To evaluate the clinical efficacy and satety of 90Sr-90Y application combined with corn paste in the treatment of corns. Methods 85 patients with corns in the First People's Hospital of Tianmen from September 2019 to December 2020 were selected and randomly divided into group A, group B and group C based on random number table. In group A, 28 cases were treated with simple 90Sr-90Y application; in group B, 27 cases were treated with 90Sr-90Y application plus intermittent corns paste; in group C, 30 cases were treated with 90Sr-90Y application plus continuous corns paste.The treatment effect, recovery time, recurrence rate and incidence of adverse reactions of the three groups were compared. Results The cure rates of the three groups were 78.57% (21/28), 81.48% (22/27) and 83.33% (25/30), with no significant difference (P > 0.05); the total effective rates were 92.86% (26/28), 92.59% (25/27) and 96.67% (29/30), the difference was not significant (P > 0.05); the cure time was (5.67 ± 1.80) weeks, (2.82 ± 1.11) weeks and (2.24 ± 1.05) weeks, the cure time of the B and C groups was significantly shorter than that of the A group (P < 0.05); The incidence of adverse reactions were 9.52% (2/21), 4.55% (1/22) and 4.00% (1/25), respectively, the difference was not significant (P > 0.05); the incidence of adverse reactions were 3.57% (1/28), 11.11% (3/27) and 26.67% (8/30), the incidence of adverse reactions in group C was higher than Group A (P < 0.05). Conclusion The combination of 90Sr-90Y application and intermittent corns paste in the treatment of corns has good curative effect, low recurrence rate, short cure time and few adverse reactions. It is worthy of clinical promotion.
