RESUMEN
<p><b>OBJECTIVE</b>To observe the clinical effect of Pifubing Xuedu Pill (PXDP) combined with Diyin Tablet (DYT) in treating patients with psoriasis.</p><p><b>METHODS</b>Sixty patients were divided into 2 groups by randomized controlled method. DYT was orally taken by all patients, while XDP was given additionally to patients in the treated group, the medication was continued for 1 month. The therapeutic effect, toxic and adverse reaction were observed.</p><p><b>RESULTS</b>In the treated group, 7 patients were cured, 11 basically cured, 4 markedly effective, 7 improved, and 1 ineffective, with the clinical cured rate of 60.0% and the total effective rate 73.3%. In the control group, 3 were cured, 4 basically cured, 9 markedly effective, 10 improved, and 4 ineffective, with the clinical cured rate of 23.3% and the total effective rate 53.3%. No significant difference was shown in comparison of the total effective rate between the two groups (chi2 = 0.27, P > 0.05), however, significant difference was shown in comparison of the clinical cured rate (chi2 = 6.48, P < 0.05) between them. The toxic and adverse reaction in the treated group was obviously lower than those in the control group (t = 5.27, P <0.05).</p><p><b>CONCLUSION</b>DYT combined with PXDP in treating psoriasis shows better therapeutic effect, with quicker initiation, lesser toxic and adverse reaction, and higher efficacy than using DYT alone.</p>
