Effect of Modified Erchentang on Expressions of Chemokine Receptor CXCR1/2 and CXCL8 in Patients with AECOPD
To observe the clinical efficacy of modified Erchentang on CXC chemokine ligand receptors (CXCR1/2)and their ligands CXCL8
macrophage inflammatory protein -2(MIP-2) in patients of chronic obstructive pulmonary disease(AECOPD)at acute exacerbation stage
and assess the effect and mechanism of modified Erchentang on anti-inflammatory in patients of AECOPD.
Method:
2
This study was a multicenter
randomized single blind
controlled trial. The authors selected 200 cases in conformity to the standards of AECOPD. The AECOPD patients were randomly divided into modified Erchentang group and control group. In addition to the western medicine
modified Erchentang was also given to the modified Erchentang group
and Jizhitangjiang was given to the control group for 14 days. Each group was observed for the alleviation of the symptoms. Euzyme-linked immunosorbent assay (ELISA) was used to determine the levels of CXCL8 and MIP-2 in the patients' plasma of all groups before and after treatment. Western blot were used to detect the levels of CXCR1
CXCR2 and CXCL8 protein in peripheral blood mononuclear cells(PBMCs). Immunocytochemistry (ICC) method was used to detect the expressions of CXCL8
CXCR1 and CXCR2 protein in PBMCs.
Result:
2
The level of CXCL8 in plasma
and the expressions of CXCR1
CXCR2 and CXCL8 mRNA and protein in the modified Erchentang group were decreased significantly than those in the control group(
P
<
0.05
P
<
0.01).
Conclusion:
2
Modified Erchentang has an anti-inflammatory effect on AECOPD. Its mechanism may be related to the down-regulation of the expressions of CXCL8
CXCR1 and CXCR2
the reduction of synthesis and release of CXCL8 and MIP-2
the inhibition of the chemotaxis and activity of inflammatory cells
