Methods： Forty mice were divided into four groups, including normal control, FDDHS （induced by Radix et Rhizoma Rhei recipe and influenza virus A1 FM1 model）, HQD, and the ribavirin groups （10 in each）. The normal control and FDDHS groups were administered normal saline. HQD and the ribavirin groups were administered HQD and ribavirin intragastrically once daily at a dose of 64 g/（kg.d） and 0.07 g/（kg.d）, respectively for 7 days. Lethargy, rough hair, diarrhea, tongue color and sole color were evaluated for pathological changes in morphology. The tongue and lung tissues were collected for histology. The CD14 and toll-like receptor 4 （TLR4） expression levels were measured using real-time quantitative polymerase chain reaction. Results： More than 80% of the FDDHS mice showed hypokinesia and lethargy, and pathological changes associated with rough hair, diarrhea, tongue color and sole color. With advanced treatment for 7 days, the thick greasy tongue fur of the HQD and ribavirin groups were thinner than that of the FDDHS group （P〈0.05）, and it was the thinnest in the ribavirin group as compared with that in other groups （P〈0.05）. The CD14 and TLR4 expression levels in the lung tissues of HQD and ribavirin groups significantly delined compared with the model group （P〈0.05 or P〈0.01）. CD14 was down-regulated more remarkably in the HQD group compared with the ribavirin group （P〈0.05）, whereas the converse was true with TLR4 （P〈0.05）. Conclusions： We established a FDDHS mouse model showing systemic clinical symptoms. Both HQD and ribavirin can inhibit the expression of CD14 and TLR4 in FDDHS mice, while the effect of ribavirin might be much more violent. The expression changes of CD14 and TLR4 consistently refers to lipopolysaccharide, the commonly and hotly inducing factor in FDDHS.展开更多
目的:通过建立不同病机引起的两种湿热模型,探索湿热证的肠道菌群组成变化规律。方法:将BALB/c小鼠分成正常组、LPS组、模型A组、模型B组4组;模型A、B组给于高蛋白饲料饲养、20%蔗糖水饮用,置于设定温度为(35±0.15)℃,湿度为80%~90...目的:通过建立不同病机引起的两种湿热模型,探索湿热证的肠道菌群组成变化规律。方法:将BALB/c小鼠分成正常组、LPS组、模型A组、模型B组4组;模型A、B组给于高蛋白饲料饲养、20%蔗糖水饮用,置于设定温度为(35±0.15)℃,湿度为80%~90%的人工气候箱中模拟外湿热环境,模型A组给于"花生油脂+白酒"灌胃、模型B组给于"20%番泻叶药液+白酒"灌胃42 d致脾虚;于造模56 d LPS组、模型A、B组给于1mg/kg剂量的脂多糖LPS工作液腹腔注射完成湿热模型造模,于注射LPS工作液后6 h取材进行相关指标检测。结果:模型A、B组均出现了湿热证类似的临床表现、体征和相关炎症因子的改变,干扰素γ(INF-γ)、肿瘤坏死因子α(TNF-α)水平均出现升高;两种湿热模型肠道菌群大肠杆菌属、肠球菌属、梭菌属均出现不同程度的含量增加;双歧杆菌属、乳杆菌属在模型A组中含量增加而在模型B组中含量减少。结论:温病湿热证存在肠道菌群结构失调,湿热证模型出现大肠杆菌属、肠球菌属、梭菌属等条件致病菌过度增长;而双歧杆菌属、乳杆菌属等益生菌的含量受湿热发病机制的影响出现含量表达的差异,脾阳虚为内湿基础的湿热证双歧杆菌属、乳杆菌属含量减少,湿邪困扰为内湿基础的湿热证双歧杆菌属、乳杆菌属含量增多。展开更多
