方法
2
8周龄SD雄性大鼠120只,随机分为正常组20只和造模组100只。正常组给予大鼠维持饲料喂养,造模组给予高脂饲料喂养。造模成功大鼠随机分为模型组、阳性药(二甲双胍)组、大柴胡汤低、中、高剂量组(4.25,8.5,17 g·kg

Objective
2
To observe the effects of Da Chaihutang on Cyclic adenosine monophosphate (cAMP)-response element binding protein (CREB)/peroxisome proliferator-activated receptor-gamma coactivator-1 alpha (PGC-1
α
) pathway in nutritionally obese rats and the protective mechanism on liver mitochondria.
Method
2
A total of 120 8-week-old male SD rats were randomly divided into a control group (
n
=20) and an experimental group (
n
=100). The rats in the control group were fed on a normal diet, while those in the experimental group were administered with a high-fat feed. Successfully modeled rats were randomly divided into a model group, a positive drug (metformin) group, and low-, medium- and high-dose Da Chaihutang groups (4.25, 8.5, and 17 g∙kg
-1
, respectively), with 20 rats in each group. After treatment with Da Chaihutang, the body weight, Lee's index, liver mitochondrial membrane potential and mitochondrial ultrastructure, PGC-1
α
expression and CREB phosphorylation of each group were measured and compared.
Result
2
Compared with the control group, the model group showed increased body weight and Lee's index (
P
<
0.01), whereas decreased mitochondrial membrane potential, PGC-1
α
expression, and CREB phosphorylation level (
P
<
0.01). As compared with the model group, Da Chaihutang significantly reduced the body weight and Lee's index of obese rats (
P
<
0.05,
P
<
0.01), enhanced liver mitochondrial membrane potential (
P
<
0.05,
P
<
0.01) to protect the integrity of mitochondrial structure, up-regulated PGC-1
α
expression and promoted CREB phosphorylation (
P
<
0.05,
P
<
0.01).
Conclusion
2
Da Chaihutang protects the structure and function of mitochondria and inhibits weight gain in obese rats by activating the CREB/PGC-1
α
pathway.
