RESUMEN
<p><b>OBJECTIVE</b>To observe the clinical effects of Erhuang Powder (EHP) in promoting the wound healing of cervical columnar epithelium ectopy after physiotherapy.</p><p><b>METHODS</b>Sixty-four patients with moderate and severe cervical columnar epithelium ectopy accompanied with contact bleeding were assigned to the treatment group (34 cases) and the control group (30 cases) according to table of random digit. Physiotherapy of the cervix was given to all patients. EHP was externally applied to the affected site of patients in the treatment group once every 3 days. Five times consisted as one therapeutic course, totally for 2 courses. The therapeutic effects, the wound healing time, the vaginal fluid quantity, the vaginal fluid discharge time, the wound infection, and adverse reaction were observed in the two groups.</p><p><b>RESULTS</b>The healing rate of the treatment group was 85.29% (29/34), higher than that of the control group (50%, 15/30) after 8 weeks of treatment, showing statistical difference (P < 0.1). The average wound healing time of the treatment group (3.2 - 0.8 weeks) was shorter than that of the control group (5.3 +/- 0.9 weeks), showing statistical difference (P < 0.5). The vaginal fluid quantity and the vaginal fluid discharge time in the treatment group were superior to those in the control group, showing statistical difference (P < 0.5, P < 0.1). Increased vaginal secretion accompanied with foreign odor or infection occurred in 2 patients of the control group. No adverse reaction or infection occurred in the treatment group.</p><p><b>CONCLUSIONS</b>Local application of EHP could promote the wound healing of cervical columnar epithelium ectopy after physiotherapy. It could improve its healing rate. Therefore, it was one ideal and reliable method, and worthy of clinical spreading.</p>
