摘 要 目的 基于“异病同治”理论探讨补气通窍方对免疫球蛋白 A 肾病(IgAN)大鼠肠道菌群及免疫平衡的调节作用。方法
将雄性SD大鼠随机分为空白组(Normal组)和造模组。造模组大鼠以灌胃牛血清白蛋白+皮下注射四氯化碳和蓖麻油混合液+尾
静脉注射脂多糖的方式构建IgAN大鼠模型。将造模成功的大鼠随机分为模型组(Model组)、补气通窍方低剂量组(BQTQ-L组)、
补气通窍方高剂量组(BQTQ-H组)、阳性对照组(BZP组),每组15只。BZP组灌胃盐酸贝那普利10 mg/kg,BQTQ-L组、BQTQ-H
组大鼠分别灌胃补气通窍方9.81、19.62 g/kg(以生药量计),Normal组和Model组大鼠灌胃等体积生理盐水,每天1次,连续8周。
分别于实验第 8、10、12、14、16 周检测各组大鼠的 24 h 尿蛋白(24 h UTP)含量;于末次给药后检测其血清肌酐(Scr)和血尿素氮
(BUN)含量,观察其肾组织病理改变和肾小球IgA免疫复合物沉积情况;分析各组小鼠的肠道菌群变化情况和外周血辅助性T细
胞17(Th17)、调节性T细胞(Treg)比例和二者比值(Th17/Treg)。结果 与Model组相比,BQTQ-L组、BQTQ-H组大鼠肾小球系膜
细胞增生和基质增生均有所减轻,炎症细胞浸润减少;其24 h UTP含量(BQTQ-L组第14、16周,BQTQ-H组第12、14、16周),Scr、
BUN含量,IgA阳性区域荧光强度,厚壁菌门的相对丰度,Th17比例,Th17/Treg均显著降低(P<0.05);Chao1指数、Observed spe‐
cies指数、Shannon指数、Simpson指数(BQTQ-H组除外),拟杆菌门的相对丰度和Treg比例均显著升高(P<0.05);差异微生物包
括c_Clostridia(BQTQ-L组vs. Model组)、g_Ruminococcus(BQTQ-H组vs. Model组)等。结论 补气通窍方可能通过调控肠道菌群
稳态和Th17/Treg免疫平衡来缓解IgAN大鼠肾损伤,发挥肾脏保护作用。

ABSTRACT OBJECTIVE To explore the regulatory effects of Buqi tongqiao formula on intestinal flora and immune balance in
immunoglobulin A nephropathy (IgAN) rats based on the theory of “treating different diseases with the same therapy”. METHODS
Male SD rats were randomly assigned to the Normal group and the modeling group. IgAN rat models were established in the
modeling group by intragastric administration of bovine serum albumin, subcutaneous injection of carbon tetrachloride and castor
oil mixture, and tail vein injection of lipopolysaccharide. Successfully modeled rats were then randomly divided into the model
group (Model group), Buqi tongqiao formula low-dose group (BQTQ-L group), Buqi tongqiao formula high-dose group (BQTQ-
H group), and positive control group (BZP group), with 15 rats in each group. BZP group received intragastric administration of
benazepril hydrochloride (10 mg/kg), while BQTQ-L and BQTQ-H groups were given Buqi tongqiao formula at doses of 9.81 and
19.62 g/kg (calculated as raw herb weight), respectively. The Normal group and the Model group received an equal volume of
normal saline intragastrically, once a day, for 8 consecutive weeks. The 24-hour urinary total protein (24 h UTP) contents were
measured at weeks 8, 10, 12, 14 and 16 of the experiment.
