摘要: 目的 研究小儿感冒宁颗粒(XRG)对流感病毒感染小鼠肺炎模型中单核细胞趋化蛋白-1(MCP-1)表达,以及丝裂原活化蛋白激酶(MAPK)中ERK途径和核转录因子(NF-κB)途径的影响。方法 以流感病毒FM1株及PR8株分别感染小鼠,治疗组给予小儿感冒宁颗粒28、14及7 g·kg-1 3个剂量组,利巴韦林为阳性药对照。感染病毒后5天取材,采用酶联免疫技术,测定流感病毒PR8株感染的小鼠肺炎模型血清中的MCP-1表达;采用Western blot技术,测定流感病毒FM1株感染的小鼠肺炎模型肺组织中细胞外调节蛋白激酶(ERK)和NF-κB的蛋白表达。结果 小儿感冒宁颗粒可降低流感病毒感染后血清中MCP-1的含量,3个剂量组与模型对照组比较具有显著性差异(P<0.05)。小儿感冒宁颗粒中剂量可降低流感病毒感染后肺组织中p-Erk蛋白表达降低,与模型对照组比较具有显著性差异(P<0.05)。小儿感冒宁颗粒3个剂量均有降低肺组织中NF-κB蛋白表达的趋势。结论 小儿感冒宁颗粒可通过抑制MCP-1炎症因子表达、抑制ERK和NF-κB信号通路激活的方式,来增强机体的免疫作用,控制流感病毒在体内的增殖,从而缓解炎症反应,达到药物的抗病毒作用。

Abstract: Objective To explore the influence of Xiaoerganmaoning granules (XRG) on the express of MCP-1, ERK and NF-κB signaling pathway in influenza virus infected mice.Methods The mice were infected with influenza virus FM1 and PR8 strain. The treatment groups were given 3 doses levels of Xiaoerganmaoning Granules (28, 14 and 7 g·kg-1). The ribavirin was the positive drug control. After 5 days, enzyme-linked immunoassay (ELISA) method was adopted to study the content of MCP-1 in serum of influenza virus PR8 infected mice. The western blot was used to observe the protein expression of ERK and NF-κB signaling pathway in lung tissue of influenza virus FM1 infected mice.Results Compared with the model control group, the content of MCP-1 was decreased significantly by XRG. and the content of MCP-1 in the 3 XRG groups (P<0.05). Compared with the model control group, the protein expression of p-Erk in XRG medium dose group was observably reduced (P<0.05). The 3 XRG groups had the tendency of reducing the expression of NF-κB.Conclusion XRG could alleviate the inflammatory reaction and exert antiviral effect by inhibiting the MCP-1, ERK and NF-κB signaling pathway to enhance the immune function and control the proliferation of influenza virus in vivo.
