摘要: 目的 研究百蕊颗粒对流感病毒致小鼠病毒性肺炎的影响及可能作用机制。方法 将ICR小鼠按体重随机分组,分别为正常对照组,模型对照组,百蕊颗粒18.84、9.42、4.71 g·kg-1组,阳性对照药磷酸奥司他韦胶囊组。除正常对照组外,其余各组小鼠滴鼻感染流感病毒构建小鼠病毒性肺炎模型,测定小鼠的存活时间、死亡率;并测定病毒感染不同阶段(感染3、5、7 d后)正常对照组、模型对照组、百蕊颗粒18.84 g·kg-1组、磷酸奥司他韦胶囊组小鼠的体重、肺指数、肺组织病毒载量、血清炎症因子[白细胞介素-6(IL-6)、γ-干扰素(IFN-γ)、肿瘤坏死因子-α(TNF-α)]水平。结果 甲型流感病毒感染小鼠后,与正常对照组相比,模型对照组小鼠体重下降,肺指数、肺组织病毒载量、血清炎症因子水平升高,表明流感病毒性肺炎模型成立;与模型对照组相比,百蕊颗粒18.84、9.42、4.71 g·kg-1组存活时间明显延长(P<0.01),死亡率明显降低(P<0.01),感染5、7 d后百蕊颗粒18.84 g·kg-1组小鼠体重显著升高(P<0.05),感染3、5、7 d后百蕊颗粒18.84 g·kg-1组小鼠肺指数值显著降低(P<0.05);感染5 d后百蕊颗粒18.84 g·kg-1组病毒载量较模型组明显降低(P<0.01),感染7 d后百蕊颗粒18.84 g·kg-1组血清IL-6含量较模型对照组显著降低(P<0.01)。结论 百蕊颗粒对流感病毒感染致小鼠病毒性肺炎具有治疗作用,可提高病毒感染小鼠体重、降低肺指数,延长病毒感染小鼠存活时间、降低死亡率,其可能是通过降低肺组织病毒载量、血清炎症因子含量发挥抗流感作用。

Abstract: Objective To study the therapeutic effect and mechanism of Bairui granules against influenza virus-induced viral pneumonia in mice. Methods According to body weight, ICR mice were randomly divided into groups: the normal control group, model control group, Bairui granules 18.84、9.42、4.71 g·kg-1 groups, and the positive control oseltamivir phosphate capsule group. Except the normal control group, all these groups of mice were intranasally infected with influenza virus to establish a mouse model of viral pneumonia. The survival and mortality of the mice were observed. Furthermore, the body weight, lung index, viral load in lung tissue, and serum levels of inflammatory factors interleukin-6 (IL-6), γ-interferon (IFN-γ), and tumor necrosis factor-α (TNF-α) at 3, 5 and 7 days post infection (dpi) were measured in the normal control group, model control group, Bairui granules 18.84 g·kg-1 group and oseltamivir phosphate capsule group. Results Compared with the normal control group, the mice infected with influenza A virus showed a decrease in weight but an increase in the lung index, viral load in lung tissue, and the levels of serum inflammatory factors, indicating that a mouse model for influenza virus pneumonia was established. Compared with the model control group, the Bairui granules 18.84, 9.42, 4.71 g·kg-1 groups showed a significant prolongation in survival time (P<0.01) and a significant decrease in mortality after being infected by influenza virus (P<0.01). In addition, the Bairui granules 18.84 g·kg-1 group exhibited a significant increase in body weight (P<0.05) at 5 and 7 dpi, and a significant decrease in the lung index (P<0.05) at 3,5 and 7 dpi. Moreover, the viral load in the Bairui granules 18.84 g·kg-1 group was significantly lower than that of the model control group (P<0.01) at 5 dpi, and the serum IL-6 content in the Bairui granules 18.84 g·kg-1 group was significantly lower than that of the model control group (P<0.01) at 7 dpi. Conclusion Bairui granules show some therapeutic effect against viral pneumonia in mice induced by influenza virus infection by increasing body weight, decreasing the lung index, prolonging survival, and reducing mortality in virus-infected mice.
