Mechanism of Huangliantang in Treatment of Chronic Non-atrophic Gastritis Based on Harmonization Method
Harmonization method is one of the eight unique methods of traditional Chinese medicine with important application value in clinic. Based on the effect of harmonization method in regulating cold and heat
the mechanism of Huangliantang in treating chronic non-atrophic gastritis(CNAG) on rats were studied.
Method:
2
Rats were divided into normal group (
n
=10) and CNAG model group (
n
=50). The model of CNAG rats was induced by chemical stimulation combined with hunger and satiety. The model group was randomly divided into 5 groups
namely the model group
the Jinghua Weikang pill treatment group
and the high
middle and low-dose Huangliantang groups
with 8 rats in each group. After the model was successfully established
the Jinghua Weikang pill treatment group (0.04 g·kg
-1
)
the high
middle
low dose Huangliantang group (11.00
5.48
2.74 g·kg
-1
)
the blank group and the model group were given the same dose of saline for 4 weeks
and then the samples were collected. The histological changes of gastric mucosa were observed by hematoxylin-eosin (HE) staining. The serum levels of interleukin-6 (IL-6)
interleukin-1
β
(IL-1
β
) and interleukin-8 (IL-8) were measured by enzyme-linked immunosorbent assay (ELISA). immunohistochemistry(IHC) was used to detect nuclear factor-
κ
B (NF-
κ
B) and its inhibitory protein receptor (I
κ
B
α
)
protein expression. Real-time quantitative fluorescence polymerase chain reaction (Real-time PCR) was used to detect I
κ
B
α
NF-
κ
B mRNA expressions.
Result:
2
In the model group
the gastric mucosa was damaged
a large number of inflammatory cells were infiltrated
the serum inflammatory factors increased significantly
mRNA and protein expressions of I
κ
B
α
decreased
and mRNA and protein expressions of NF-
κ
B increased in the gastric tissue (
P
<
0.01). In each treatment group
the inflammation of gastric mucosa was improved to some extent
the serum inflammatory factor was decreased
the mRNA expression of I
κ
B
α
was up-regulated
I
κ
B
α
protein was increased
while the expression of NF-
κ
B mRNA was down-regulated
and NF-
κ
B protein was decreased. The Jinghua Weikang pill treatment group and the high-dose Huangliantang group had the most obvious improvement (
P
<
0.05
P
<
0.01).
Conclusion:
2
Huangliantang for regulating cold and heat based on the harmonization method can effectively alleviate the degree of gastric mucosal injury
and reduce serum inflammatory factors in CNAG rats. The mechanism is related to the up-regulation of I
