Objective
2
To investigate the effects and mechanism of Zuogui Jiangtang Tongmai prescription (ZJTP) on human umbilical vein endothelial cells (HUVECs) damaged by high glucose combined with lipopolysaccharide (LPS).
Method
2
The survival rate of cells was determined by cell counting kit-8 (CCK-8), and the level of tumor necrosis factor-
α
(TNF-
α
) was determined by enzyme-linked immunosorbent assay (ELISA) to determine the optimal injury concentration and action time of LPS, as well as the optimal action concentration of ZJTP drug-containing serum. HUVECs were divided into a blank control group, a model group, a ZJTP drug-containing serum group, and an SCFA mixed liquid group. ELISA was used to detect the level of endothelin-1 (ET-1), nitric oxide (NO), interleukin-1
β
(IL-1
β
), interleukin-6 (IL-6), and TNF-
α
. Western blot was performed to detect the protein expression of G protein-coupled receptor43 (GPR43),
β
-suppressor protein-2 (
β
-arrestin-2), nuclear factor-
κ
B suppressor
α
(I
κ
B
α
), and nuclear factor
κ
B p65 (NF-
κ
B p65). The nucleation of NF-
κ
B p65 was observed by immunofluorescence staining (IF). The role of GPR43 in the regulation of inflammatory injury was observed by means of small interfering ribonucleic acid (siRNA). The cells after intervention were divided into an empty carrier group, a ZJTP drug-containing serum group, a Si-GPR43 group, and a Si-GPR43 + ZJTP drug-containing serum group. The content of IL-1
β
, IL-6, and TNF-
α
was detected by ELISA. The protein expression of pathways was detected by Western blot. IF was used to observe the nucleation of NF-
κ
B p65.
Result
2
The optimal molding condition was 1 mg·L
-1
LPS for 24 h. The optimal drug intervention condition was 5% ZJTP drug-containing serum for 24 h. Compared with the blank control group, the content of ET-1 in the model group was significantly increased, and the content of NO was significantly decreased (
P
<
0.01). The levels of inflammatory factors were significantly increased (
P
<
0.01). The expressions of GPR43 and I
κ
B
α
were significantly decreased, while the protein expressions of
β
-arrestin-2 and NF-
κ
B p65 were significantly increased (
P
<
0.01). NF-
κ
B p65 protein was transferred from the extranuclear to the intranuclear (
P
<
0.01). Compared with the model group, the content of ET-1 in the ZJTP drug-containing serum group was decreased, and the content of NO was increased (
P
<
0.05). The levels of inflammatory factors decreased (
P
<
0.05). The protein expressions of GPR43 and I
κ
B
α
were increased, while the expressions of
β
-arrestin-2 and NF-
κ
B p65 were decreased (
P
<
0.05). The amount of NF-
κ
B p65 transferred from the intranuclear to the extranuclear decreased (
P
<
0.01). The mechanism study showed that compared with the Si-GPR43 group, the content of IL-1
β
, IL-6, and TNF-
α
were significantly decreased after treatment with ZJTP drug-containing serum (
P
<
0.01). The protein expressions of GPR43 and I
κ
B
α
were significantly increased (
P
<
0.01), while the protein expressions of
β
-arrestin-2 and NF-
κ
B p65 were significantly decreased (
P
<
0.01). The amount of NF-
κ
B p65 transferred from the extranuclear to the intranuclear decreased (
P
<
0.01).
Conclusion
2
ZJTP has a protective effect on HUVECs with high glucose and LPS-induced inflammatory injury, which may be related to the regulation of GPR43/
β
-arrestin-2/I
κ
B
α
/NF-
