目的观察清金颗粒对耐甲氧西林金黄色葡萄球菌(MRSA)肺炎模型小鼠的干预效应。方法采用菌液滴鼻法制作肺炎小鼠模型。将实验小鼠随机分为空白组、模型组、西药组和中药组,造模后第3日开始给药,西药组给予利奈唑胺灌胃,中药组给予清金颗粒灌胃,空白组和模型组给予生理盐水灌胃。造模后每日观察小鼠体质量变化及临床表现,第3、10日CT检测肺部影像学变化,HE染色观察肺组织病理变化,检测肺部载菌量。结果造模组小鼠感染后第1日体质量显著下降,感染后第3日肺部CT示两肺充满炎性渗出物;给药后第7日中药组较模型组小鼠肺部炎症明显减轻,炎性渗出物减少,仅有散在炎性渗出物,同时肺部炎性病理表现减轻,且肺部载菌量明显降低(P0.05),但较西药组效果稍差(P0.05)。结论清金颗粒能够显著降低小鼠肺部载菌量,减少肺组织炎细胞浸润,对MRSA感染肺炎小鼠有治疗作用。 相似文献

Prof. Ren ZHANG's experience in clinical treatment of neuromyelitis optica spectrum disorders (NMOSD) is summarized in this paper. The pathogenesis of this kind of disease is complicated. Prof. Ren ZHANG treats it in both symptoms and root cause.
