清肺饮对呼吸道病毒感染及其NK、IFN-γ、IL-2的影响

Treatment of Virus Infection of Respiratory Tract with Qingfei Decoction: Its Effects on Serum Natural Killers, Interferon-γ and Interleukin-2

观察清肺饮对呼吸道病毒感染的疗效。选择呼吸道病毒感染患者 60例 ,随机分为清肺饮组36例、抗病毒口服液组 2 4例 ,观察治疗前后症状、体征、血清内NK(自然杀伤细胞 )、IFN(干扰素 )、IL - 2 (白细胞介素 - 2 )的变化。结果示症状有效率、体征改善清肺饮均明显优于抗病毒口服液 ;清肺饮可明显提高呼吸道病毒感染患者NK细胞活力、IFN -γ水平和IL - 2水平。提示清肺饮对呼吸道病毒感染的疗效优于抗病毒口服液 ,并可明显提高NK、IFN -γ、IL - 2水平。

With Kangbingdu Oral Solution (KOS) as a control, the therapeutic effects of Qingfei Decoction (QD) on virus infection of respiratory tract (VIRT) were investigated. 60 VIRT patients were randomly divided into QD-group (36 cases) and KOS-group (24 cases). The changes in the severity of the symptoms and signs, the activity of serum natural killers (NK), and the levels of serum interferon (IFN-γ) and interleukin-2 (IL-2) were observed before and after the treatment with the two preparations respectively in the patients in the two groups. The results showed that the effective rate of QD for treating the symptoms and signs of VIRT was much higher than that of KOS, and QD could markedly increase the activity of NK and the levels of IFN-γand IL-2, which suggests that QD is better than KOS for treating VIRT.
