目的
2
研究火绒草黄芪混煎液(HRCHQ)对系膜增生性肾小球肾炎(MsPGN)模型大鼠的改善作用及机制。
方法
2
将70只大鼠按体质量分为假手术组(
n
=10)和造模组(
n
=60)。假手术组大鼠行假手术,造模组大鼠采用免疫学方法(弗氏佐剂+牛血清蛋白+脂多糖)复制MsPGN模型。将造模成功的50只大鼠按体质量随机分为模型组和HRCHQ 高、中、低剂量组(4.05、2.03、1.02 g/kg)以及盐酸贝那普利片组(20 mg/kg),每组各10只。假手术组、模型组大鼠灌胃蒸馏水,其余各组大鼠灌胃相应药液15 mL/kg,每天1次,连续5周。末次给药后,测定大鼠血清中总蛋白、白蛋白、尿素氮含量,采用免疫组织化学染色法检测大鼠肾脏组织中转移生长因子β
1
(TGF-β
1
)、肿瘤坏死因子α(TNF-α)的表达,采用免疫荧光法检测大鼠肾脏组织中补体C3的表达,采用Western blot法检测大鼠肾脏组织中磷脂酰肌醇3激酶/蛋白激酶B/糖原合酶激酶3β(PI3K/Akt/GSK3β)信号通路相关蛋白的磷酸化水平及纤连蛋白(FN)的表达水平。
结果
2
与模型组比较,HRCHQ高剂量组大鼠血清中总蛋白、白蛋白含量均显著升高(
P
<0.05或
P
<0.01);血清中尿素氮含量,肾脏组织中TGF-β
1
、TNF-α、FN、补体C3表达水平和PI3K、Akt、GSK3β蛋白的磷酸化水平均显著降低(
P
<0.05或
P
<0.01)。
结论
2
HRCHQ可通过减少系膜细胞增殖以及抑制PI3K/Akt/GSK3β信号通路活性来改善MsPGN。
OBJECTIVE
2
To study the improvement effects of Huorongcaohuangqi (HRCHQ) admixture decoction on mesangial proliferative glomerulonephritis (MsPGN) model rats and its mechanism.
METHODS
2
Totally 70 rats were divided into sham operation group (
n
=10) and mod
eling group (
n
=60) according to body weight. Sham operation group underwent sham operation,and MsPGN model was induced by immunological method (Freund’s adjuvant+BSA+lipopolysaccharide) in modeling group. After successfully modeling, 50 rats were randomly divided into model group,HRCHQ high-dose, medium-dose and low-dose groups (4.05, 2.03,1.02 g/kg), Benazepril hydrochloride tablet group (20 mg/kg), with 10 rats in each group. Sham operation group and model group were given distilled water intragastrically; other groups were given relevant medicine intragastrically 15 mL/kg, once a day, for consecutive 5 weeks. After last administration, the contents of total protein, albumin and urea nitrogen were determined in the serum of rats. The expressions of transforming growth factor β
1
(TGF-β
1
) and tumor necrosis factor α (TNF-α) in renal tissue were detected by immunohistochemistry; the expression of complement C3 in renal tissue was detected by immunofluorescence. The phosphorylation level of phosphatidylinositol 3 kinase/protein kinase B/glycogen synthase kinase 3β (PI3K/Akt/GSK-3β) signal pathway related proteins and expression level of fibronectin (FN) in renal tissue were detected by Western blot.
RESULTS
2
Compared with model group, the serum contents of total protein and albumin were increased significantly in HRCHQ high-dose group (
P
<0.05 or
P
<0.01).The serum content of urea nitrogen, the expressions of TGF-β
1
,TNF-α,FN and complement C3, and the phosphorylation levels of PI3K, Akt and GSK3β protein were all decreased significantly (
P
<0.05 or
P
<0.01).
CONCLUSIONS
2
HRCHQ can improve MsPGN by reducing the proliferation of mesangial cells and inhibiting the activity of PI3K/Akt/GSK3β signaling pathway.
