[Methods]Eucalyptus oil samples with different dilution ratio were detected by TLC. Eucalyptus oil was intragastrically administered to mice,serum samples of different eucalyptus oil doses,different intragastric administration methods and different blood sampling times were collected. The above samples were detected by TLC,and the above results were verified by gas chromatography. [Results] TLC can detect concentration difference of eucalyptus oil samples with different dilution ratio. TLC can provide qualitative and semi-quantitative detection of eucalyptus oil in serum. High,medium and low dose of eucalyptus oil in serum had different effects on the growth of MCF-7 cells in the SD rats( P < 0. 05). [Conclusions] TLC can be used to guide the preparation of drug containing serum of eucalyptus oil.展开更多

Methods： Thirty-two rats were randomly divided into four groups： the blank control group treated with distilled water, the positive control group treated with simvastatin （1.8 mg/kg）, the test group I treated with Chinese herbal compound of XS （0.135 g/kg）, and the test group 1T treated with Chinese herbal compound of XS （0.135 g/kg） and HL （0.135 g/kg）. All the treatments were administered for 7 successive days by gastrogavage. Rats＇ blood serum was harvested 1 h after the last administration to prepare respective drug- containing serum. HUVECs were exposed to ox-LDL （100 μg/mL） to induce cell injury model and incubated with corresponding drug-containing serum for 24 h. Untreated HUVECs were set for blank control. Levels of interleukin-6 （IL-6）, tumor necrosis factor-α （TNF-α）, and soluble intercellular adhesion molecule-1 （slCAM-1） in supematant of cultured HUVECs were determined by enzyme-linked immunosorbent assay （ELISA）. HUVEC surface expressions of ICAM-1 and E-selectin were determined by flow cytometry. Results： Levels of IL-6, TNF-α, and sICAM-1 in the supernatant of HUVECs as well as the cell surface expressions of ICAM-1 and E-selectin significantly increased after 24-h ox-LDL stimulation （P〈0.01）, while the abnormal elevations, except slCAM-1 in the test group Ⅰ, were all reduced in the treated groups （the positive control and the two test groups） significantly （P〈0.01 or P〈0.05）. Besides, the effect in the test group Ⅱ seemed somewhat higher than that in the test group Ⅰ but with no statistical significance （P〉0.05）. Conclusion： Drug-containing serum of XS plus HL has a certain inhibitory effect on the vascular endothelial inflammation response induced by ox-LDL.展开更多

Methods： Human lung adenocarcinoma A549/DDP cell strain was selected, serum pharmacology and flow cytometer （FCM） method were adopted, $180 tumor-bearing mice and normal mice were given, through gastrogavage, different doses of a decocted concentration of BSHYJDR. Serum from the abdominal aorta was taken to observe the effect of drug-serum on cisplatin （DDP） concentration, free Ca^2＋ concentration and the expression of lung drug-resistance protein LRP-56 in A549/DDP cells. Results： Compared with the drug-resistance group, the intracellular DDP concentration in the group taking a high dose and the normal group of Chinese medicine showed significant difference （P〈0.05）, while no significant difference was found in the low-dose group （P〉0.05）. Compared with the drug-resistance group, the Ca^2＋ concentration in cells and the expression of LRP in lung cancer drug-resistance cells A549/DDP of the high-dose group, the low-dose group and the normal group of Chinese medicine were significantly different （all P〈0.01）, the LRP expression of the normal group was obviously higher than that of the drug-resistance group （P〈0.05）. Cenclusien： It was indicated that serum containing Chinese medicine BSHYJDR in the tumor-bearing mice and the normal mice had certainly different, tumor-bearing mice serum containing could improve drug concentration in lung cancer drug-resistance cells, prevent the inflow and release of Ca^2＋, and inhibit the expression of the drug-resistance gene in the lung cancer drug-resistance cells, which might be the mechanism of BSHYJDR in enhancing the efficacy in reversing and inhibiting tumor.展开更多

MTT assay wasused to evaluated H9C2 cells viability. H9C2 cells were divided into normal control group, triptolide group, lipopolysaccharide(LPS) group, drug-containing serum group and mi RNA-21 inhibitor group. micro RNA-21(mi RNA-21) inhibitor was structured and transfected into H9C2 cells. Western blot and immunofluorescence assay were applied to examine toll-like receptor 4(TLR4), phosphorylated p-38(p-p38) and p-p65 expression. Quantitative real-time PCR(q RT-PCR) was used to evaluated m RNA levels of mi RNA-21. Enzyme linked immunosorbent(ELISA) was used to measure tumor necrosis factor α(TNF-α), IL-6 and IL-17 levels.RESULTS: Drug-containing serum treatment significantly increased cell viability compared to LPS treated group. q RT-PCR results indicated that mi RNA-21 levels were significantly decreased in drugcontaining serum group compared to LPS group.Early and late apoptosis in drug-containing serum group were significantly decreased compared to LPS group. Western blot and immunofluorescence assay results showed that TLR4, p-p38 and p-p65 levels in drug-containing serum group were significantly decreased compared to LPS group. ELISA findings indicated that drug-containing serum significantly decreased inflammatory cytokine levels of TNF-α, IL-6 and IL-17.CONCLUSION: Drug-containing serum of Xinfeng capsules protect against lipopolysaccharide instructed H9C2 cells from death by enhancing mi RNA-21 and inhibiting TLR4/p-p38/p-p65 signaling pathway and proinflammatory cytokines expression.展开更多
