Efficacy Evaluation of Jinchai Kangbingdu Capsule Based on Coronaryvirus Pneumonia with 'Hanshi Yidu Xifei' syndrome Model
To study the therapeutic effect of Jinchai Kangbingdu capsule based on human coronavirus pneumonia with 'Hanshi Yidu Xifei' syndrome model
in order to provide experimental basis for evaluating its effect in preventing and treating coronavirus infection.
Method
2
The 48 Balb/c mice were randomly divided into normal group
virus infection group
cold-dampness group
cold-dampness epidemic toxin lung syndrome model group
and high and low-dose Jinchai Kangbingdu capsule groups (1.76
0.88 g·kg
-1
·d
-1
). A cold-dampness stimulation combined with human coronavirus 229E infection was used to imitate human coronavirus pneumonia with 'Hanshi Yidu Xifei' syndrome model. Behavioral characteristics
lung index
viral load
and lung tissue pathological changes in Balb/c mice were observed to evaluate the therapeutic effect of Jinchai Kangbingdu capsules. The contents of interleukin-6(IL-6),IL-10,tumor necrosis factor-
α
(TNF-
α
),interferon-
γ
(IFN-
γ
) in lung tissue and motilin(MTL),gastrin(GAS) in serum were detected by enzyme-linked immunosorbent assay(ELISA)
and the contents of CD4
+
T cells
CD8
+
T cells
and B cells in peripheral blood were detected by flow cytometry.
Result
2
Compared with the cold-dampness epidemic toxin lung syndrome model group
Jinchai Kangbingdu capsule can increase the activity and response ability of 'Hanshi Yidu Xifei' syndrome model mice
and change the skin and stool status of mice. High and low-dose Jinchai Kangbingdu capsule groups can significantly reduce the lung index (
P
<
0.01)
while significantly increased the content of CD4
+
T cells
CD8
+
T cells
and B cells (
P
<
0.05
P
<
0.01). Low-dose Jinchai Kangbingdu capsule group could significantly decrease the MTL content in serum and the levels of IL-6
IL-10
TNF-
α
IFN-
γ
in lung tissue (
P
<
0.01)
whereas alleviate the pathological damage of lung tissue.
Conclusion
2
Jinchai Kangbingdu capsule showed a therapeutic effect on human coronavirus pneumonia with 'Hanshi Yidu Xifei' syndrome model
and can improve the behavioral characterization and gastrointestinal index level of cold-dampness syndrome
while reduce lung index and viral load in lung tissue. The mechanism may be related to the decrease of the content of inflammatory factors and the increase of the number of lymphocytes.
