ABSTRACT
<p><b>OBJECTIVE</b>To observe the clinical effect of Ziyin Huoxue Granule (ZHG) combined glucocorticoids and antibiotics in treatment of radiation pneumonitis.</p><p><b>METHODS</b>Totally 70 radiation pneumonitis patients were assigned to the treatment group and the control group according to random digit table, 35 in each group. All patients received glucocorticoids and antibiotics. Patients in the treatment group additionally took ZHG, one dose per day for 4 successive weeks. Watters clinical-radiologic-physiologic (CRP) score, Karnofsky Performance Status Scale (KPS) , and acute radiation injury classification [set by Radiation Therapy Oncology Group (RTOG)] were observed in the two groups before and after treatment. The application time for antibiotics and glucocorticoids was compared between the two groups.</p><p><b>RESULTS</b>All patients completed this trial, and nobody dropped out or died. There was no statistical difference in Watters-CRP scores, KPS, or RTOG between the two groups before treatment (P > 0.05). Compared with before treatment in the same group, RTOG classification was obviously improved in the two groups (P < 0.05). Compared with the control group, Watters-CRP scores decreased, KPS increased, the application time for antibiotics and glucocorticoids was reduced (P < 0.05). The efficacy of RTOG classification was better in the treatment group than in the control group, but with no statistical difference between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>ZHG combined glucocorticoids and antibiotics was superior in treating radiation pneumonitis to using glucocorticoids or antibiotics alone in elevating Watters-CRP scores, shortening the application time for glucocorticoids and antibiotics, and improving patients' physical conditions.</p>
