Effects of Suhuang Zhike Capsule on inflammation of airways in patients with allergic rhinitis and asthma syndrome / 中国综合临床

ABSTRACT

Objective:To investigate the effect of Suhuang Zhike Capsule on airway inflammation in patients with acute episode of allergic rhinitis and asthma syndrome.Methods:Eighty patients with allergic rhinitis and asthma syndrome were admitted to North China University of Science and Technology Affiliated Hospital from June 2016 to September 2017.A prospective cohort study was carried out and randomly divided into treatment group and control group with 40 patients in each group.The control group was treated with conventional anti-inflammatory, expectorant and antiasthmatic therapy, while the treatment group was treated with Suhuang Zhike Capsule.The changes of nasal symptoms and asthma clinical symptoms in the two groups were compared before and after treatment, and the changes of nitric oxide in exhaled air, eosinophils in blood and induced sputum were measured.Results:Compared with the control group, there was no significant difference in the number of eosinophils in the exhaled nitric oxide, eosinophil count in blood and induced sputum before treatment in the treatment group ((161.45±4.67)×10 -9 vs.(163.12±4.56)×10 -9, (1.59±0.53)×10 9/L vs.(1.60±0.51)×10 9/L, (1.11±0.06)×10 9/L vs.(1.18±0.09)×10 9/L; t values were 0.10, 0.44, 1.75, respectively, all P>0.05). After treatment, the exhaled nitric oxide, eosinophil count in blood and induced sputum in the treatment group were significantly lower than those before treatment((30.86±5.54)×10 -9 vs. (161.45±4.67)×10 -9; (0.32±0.05)×10 9/L vs. (1.59±0.53)×10 9/L; (0.06±0.02)×10 9/L vs. (1.11±0.06)×10 9/L, t values were 91.32, 41.63, 51.77, respectively, all P<0.01). In the treatment group, the effective rate of nasal symptom control was 85.0% (34/40) significantly higher than 62.5% (25/40) in the control group (χ 2=5.23, P<0.05), and the effective rate of asthma clinical symptom control was significantly higher than that in the control group(90.0%(36/40), 72.5%(29/40), χ 2=4.02, P<0.05). Conclusion:Suhuang Zhike capsule can obviously improve the airway inflammatory response of patients with allergic rhinitis asthma syndrome in the acute attack stage, and the combination of conventional treatment plan is helpful to improve the curative effect.
