Objective To compare the efficacy difference of Green Forsythiae Fructus and Ripe Forsythiae Fructusby using Lianqiao powder and Yinqiao powder in the classic formula; To provide experimental evidence for the guidance of "one for dual-use" of the Forsythiae Fructus. Methods The guinea pig sore model was made with Staphylococcus aureus. 40 guinea pigs were randomly divided into blank group, model group, Lianqiao powder Green Forsythiae Fructus group and Lianqiao powder Ripe Forsythiae Fructus group. The blank group and the model group were fed with normal saline, while Lianqiao powder Green Forsythiae Fructus group and Lianqiao powder Ripe Forsythiae Fructus group were treated with 1.2 g raw medicine/kg liquid Lianqiao powder Green Forsythiae Fructus and Lianqiao powder Ripe Forsythiae Fructus for 7 d. The symptom score, blood and pathological changes of guinea pig soreness were observed. The model of acute lung injury was induced by 10% LPS aerosol inhalation. 40 rats were randomly divided into blank group, model group, Yinqiao powder Green Forsythiae Fructus group and Yinqiao powder Ripe Forsythiae Fructus group. The blank group and the model group were fed with normal saline, while Yinqiao powder Green Forsythiae Fructus group and Yinqiao powder Ripe Forsythiae Fructus group were treated with 4 g raw medicine/kg liquid Yinqiao powder Green Forsythiae Fructus and Yinqiao powder Ripe Forsythiae Fructus for 10 d. The levels of IL-6, TNF-α and IL-1β in the lung lavage fluid were detected. Results The effect of Lianqiao powder Green Forsythiae Fructus on the wound healing of guinea pig sore wound was faster than that of Lianqiao powder Ripe Forsythiae Fructus, but there was no significant difference between Lianqiao powder Green Forsythiae Fructus group and Lianqiao powder Ripe Forsythiae Fructus group in inhibiting the secretion and pathological changes of guinea pig sore wound. The levels of IL-6, TNF-α and IL-1β in Yinqiao powder Green Forsythiae Fructus group was lower than that in Yinqiao powder Green Forsythiae Fructus group, without statistical significance. Conclusion It is verified that there is efficacy differences between Green Forsythiae Fructus and Ripe Forsythiae Fructus in the different Chinese herbal compound.%目的 采用经典方剂连翘散和银翘散验证青翘和老翘的功效差异,为指导连翘"一体两用"提供实验依据.方法 采用金黄色葡萄球菌制作豚鼠疮疡模型,将40只豚鼠随机分为空白组、模型组、连翘散青翘组和连翘散老翘组,空白组和模型组灌服生理盐水,连翘散青翘组和连翘散老翘组灌服1.2 g原药材/kg药液,连续7 d,观察各组模型豚鼠疮疡症状积分、血常规及病理变化.采用10%脂多糖雾化吸入法诱导大鼠急性肺损伤模型,将40只SD大鼠随机分为空白组、模型组、银翘散青翘组和银翘散老翘组,空白组和模型组灌服生理盐水,银翘散青翘组和银翘散老翘组灌服4 g原药材/kg药液,连续10 d,观察各组大鼠肺洗液白细胞介素(IL)-6、肿瘤坏死因子(TNF)-α、IL-1β 水平.结果 连翘散青翘组抑制豚鼠疮疡伤口红肿作用较老翘组起效快,但在抑制豚鼠疮疡伤口分泌物和病理改善方面与连翘散老翘组差异无统计学意义.银翘散青翘组大鼠较老翘组IL-6、TNF-α、IL-1β 含量降低,但差异无统计学意义.结论 不同复方中青翘与老翘功效有一定差异.
