To study the anti-inflammatory activity of glycyrrhizin acid, ligustrazine and puerarin. In the study, the liquichip-based high-throughput synchronous detection technique for 23 inflammatory factors, uniform design, comprehensive weight method were adopted to study the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin in inhibiting the expression of lipopolysaccharide (LPS)-induced RAW264. 7 cells and multiple inflammatory cytokines. In the study, the uniform design table U₉ (9³) was adopted to design doses of glycyrrhizin acid, ligustrazine and puerarin. The liquichip technique was used to detect the effect of different combined administration of glycyrrhizin acid, ligustrazine and puerarin on the 23 cytokines expressed in LPS-induced mouse macrophage RAW264. 7 inflammation model. The traditional Chinese medicine component optimization software and the improved least angle regression algorithm were used to analyze the dose-effect relationship among the three components and the cytokine inhibition rate and produce the regression equation. The comprehensive weight method was applied to get the optimal dose ratio of glycyrrhizic acid, ligustrazine and puerarin with highest efficacy of 25:2:13 and verify the optimal dose ratio. The verification results were consistent with the prediction trend, indicating the accuracy of the mathematical model for predicting the experiment. The experimental results showed the multi-target and multi-level efficacies of glycyrrhizic acid, ligustrazine and puerarin and the high anti-inflammatory activity of their combined administration, which provides powerful basis for subsequent drug development.

Glycyrrhizin acid and licorice flavonoids are the component of Glycyrrhiza uralensis Fisch root that has been used for various medicinal purposes in traditional oriental medicine for thousands of years. Macrophages as a principal component of immune system play an important role in the initiation, modulation and final activation of immune response against pathogens. In the present study, glycyrrhizin acid and licorice flavonoids was investigated the anti-inflammatory effect on lipopolysaccharide (LPS)-induced macrophage cell line of RAW264.7. Well-grown RAW264.7 cells were collected and randomly divided into the blank control group, the LPS(1 mg x L(-1)) group, the dexamethasone (5 mg x L(-1)) with LPS group, the glycyrrhizin acid (400, 80, 16 mg x L(-1)) with LPS group and the licorice flavonoids (200, 40, 8 mg x L(-1)) with LPS group. RAW264.7 cells were cultured in 24-well plates, pre-incubated for 4 h with different concentrations of dexamethasone, glycyrrhizin acid, or licorice flavonoids. Then cells were stimulated for 20 h with LPS. The supernatant of culture medium was collected from each well and determinated the concentrations of cytokines by means of BioPlex mouse cytokines assay. Compared with the control group, the LPS group could significantly induced relatively high levels of granulocyte colony stimulating factor (G-CSF), granulocyte-macrophage colony stimulating factor( GM-CSF), macrophage inflammatory protein-1 alpha (MIP-1α), macrophage inflammatory protein-1 beta (MIP-1β), regulated upon activation normal T cell expressed and secreted factor (RANTES), tumor necrosis factor alpha ( TNF-α), monocyte chemotactic protein 1 (MCP-1), chemokine (C-X-C motif) ligand 1 (KC), eotaxin, interleukin(IL)-1α, IL-1β, IL-3, IL-4, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, and IL-17 secretion (P < 0.05). The glycyrrhizin acid significantly inhibited IL-1β, IL-3, IL-5, IL-6, IL-10, IL-12 (p40), IL-12 (p70), IL-13, Eotaxin and TNF-α secreted by LPS-stimulated RAW264.7 cells (P < 0.05). The expression levels of IL-6 and Eotaxin were observably decreased in the licorice flavonoids with LPS group (P < 0.05). The data presented here suggested that the glycyrrhizin acid and licorice flavonoids modulate various cytokines secreted by macrophages and were important anti-inflammatory constituent of Licorice.

7.Expression of vascular cell adhesion molecule-1 in lung slices from antigen sensitized rats and pharmacological modulation.
Journal of Zhejiang University. Medical sciences 2003;32(4):319-322
OBJECTIVETo investigate the expression of vascular cell adhesion molecule-1(VCAM-1) in lung slices from antigen -sensitized rats and the modulation by drugs.
METHODSIn isolated lung slices from ovalbumin(OVA)-sensitized rats, the relative expression of VCAM-1 was determined after drug treatment and OVA challenge.
RESULTThe expression of VCAM-1 was enhanced in the sensitized rat lungs,and OVA challenge did not further increase the expression. Glycocorticosteroid dexamethasone and leukotriene cysLT receptor antagonist ONO-1078 inhibited the expression,but tachykinin NK-1 receptor antagonist SR-140333 had no such effect.
CONCLUSIONVCAM-1 expression is enhanced in the sensitized rat lungs, and antigen challenge does not further up regulate the expression. Anti-inflammatory drugs have different effects on VCAM-1 expression. Dexamethasone and ONO-1078, but not SR-140333, can inhibit the expression.
