[Effect of Biyanning Granules on local symptoms and immune function of chronic rhinosinusitis].

ABSTRACT

This study discusses the effect of Biyanning Granules on local symptoms and systemic immune function of patients with chronic rhinosinusitis with nasal polyps(CRSwNP) within the 6 months of treatment by glucocorticoid nasal spray after surgical treatment. To be specific, a total of 237 CRSwNP patients, treated in Otorhinolaryngology Head and Neck Surgery in Shanxi Bethune Hospital, were enrolled. All patients were treated by nasal endoscopy and classified into hormone group(Budesonide Nasal Spray after surgery), Chinese medicine group(Biyanning Granules after surgery), and combination group(Budesonide Nasal Spray+Biyanning Granules after surgery) with random number table method, 79 cases in each group, and the treatment lasted 3 months. The follow-up was performed from the day of discharge to 12 months after the surgery. The clinical effect was observed. The visual analogue scale(VAS) scores and sino-nasal outcome test-20(SNOT-20) scale scores were used to assess patient's subjective symptoms and quality of life. Lund-Kennedy endoscopic score(LKES), Japanese T&T olfactometry, and standard olfactory test were used to evaluate the objective curative effect on patients. The levels of interleukin(IL)-21, CD4~+CD25~+Foxp3~+Treg, and CD4~+Th17 in peripheral blood were analyzed. The incidence of complications, recurrence rate, and adverse reactions during treatment were also recorded. The total effective rate after treatment in the combination group was higher than that in the hormone group and Chinese medicine group(P<0.05). VAS scores and SNOT-20 scale scores were lower in the three groups after treatment than before treatment and lower in the combination group than in the other two groups(P<0.05). The improvement in LKES and T&T standard olfactometry test was better in the combination group than in the other two groups(P<0.05). Serum levels of IL-21 and CD4~+Th17 in the three groups were lower than before treatment. The levels in the combination group were lower than those in the other two groups and lower in the hormone group than in the Chinese medicine group(P<0.05). Serum CD4~+CD25~+Foxp3~+Treg level was higher in the three groups after treatment than before, higher in the combination group than in the other two groups, and higher in the Chinese medicine group than in the hormone group(P<0.05). During the treatment, no serious adverse reactions were observed. After treatment, the combination group showed no significant difference in the incidence and recurrence rate of complications from the hormone group and Chinese medicine group. In the treatment of CRSwNP with glucocorticoid, Biyanning Granules reduced the side effects of glucocorticoid and assisted glucocorticoid in alleviating the symptoms of patients. It significantly improved the curative effect, regulated immune imbalance, accele-rated the recovery of immune function, reduced the recurrence rate of inflammatory reaction, and improved the quality of life. The combination of Chinese and western treatment is more effective than glucocorticoid alone and warrants further clinical study in large sample size.
