ABSTRACT
<p><b>OBJECTIVE</b>To explore the effect of drug-containing serum of Chinese herbal compounds [Xiongshao Capsule (XS, for activating blood) and Huanglian Capsule (HL, for dispelling toxin)] on tumor necrosis factor-alpha (TNF-alpha)-induced adherence between human umbilical vein endothelial cells (HUVECs) and polymorphonuclear neutrophils (PMN), inflammatory reaction and expression of related proteins in mitogen-activated protein kinase (MAPK) pathway.</p><p><b>METHODS</b>Thirty-two rats were randomly divided into four groups (8 in each group) using random digit table the blank control group treated with distilled water, the test group I treated with Chinese herbal compound of XS (0.135 g/kg), the test group II treated with Chinese herbal compound of HL (0.135 g/kg), and the test group Ill treated with Chinese herbal compound of XS (0.135 g/kg) and HL (0.135 g/kg). All medication was given by gastrogavage once a day for a week. Rats' blood serum was harvested 1 h after the last administration to prepare drug-containing serum. HUVECs were exposed to TNF-alpha (100 ng/mL) to induce cell injury model and incubated with corresponding drug-containing serum (10%) for 24 h. Normal rats' serum was given to cells in the blank control group and the model group, while XC + HL containing serum was given to cells in the rest 3 groups. The adherence of HUVECs and PMN cells was detected by using rose bengal strain. Levels of E-selectin, intercellular adhesion molecule-1 (ICAM-1), and interleukin-1beta (IL-1P) in the supernatant of cultured HU-VECs were determined by ELISA. Protein expressions of mitogen-activated protein kinases p38 (p38MAPK) and extracellular signal-regulated kinase 1/2 (ERK 12) were determined by Western blot.</p><p><b>RESULTS</b>Compared with the blank control group, HUVECs were seriously injured; PMN adherence amount significantly increased; levels of E-selectin, ICAM-1, and IL-1beta increased; expression levels of p-p38MAPK and p-ERK 1/2 in the supernatant of HUVECs significantly increased in the model group (all P < 0.01). Compared with the model group, HUVECs-PMN adherence amount decreased (P < 0.05); levels of E-selectin, ICAM-1, and IL-1 beta in the supernatant of HUVECs decreased (P < 0.01, P < 0.05); expression levels of p-p38MAPK and p-ERK 1/2 of endothelial cells decreased in the test group I, II, and III (P < 0.01).</p><p><b>CONCLUSIONS</b>Drug-containing serums of activating blood, activating blood and dispelling toxin could attenuate TNF-alpha induced injury of HUVECs, inhibit HUVECs-PMN adherence and the release of adhesion factors. Its mechanism might be involved with protein phosphorylation of p38MAPK and ERK 1/2 in the MAPK pathway.</p>
