OBJECTIVETo investigate the protective effects of Jiedu Tongluo injection on cerebral edema induced by focal lesion of cerebral ischemia/reperfusion, the hydrous content of brain and the expressions of intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), E-selectin and MMP-9 in rats.

METHODThe model of brain middle cerebral artery ischemia/reperfusion was established by the thread approach. After 24 hours of reperfusion, cerebral edema formation was determined by the hydrous content of brain. The permeability of blood brain barrier was evaluated based on the leakage of Evans blue. Enzyme-linked immunoadsordent assay (ELISA)was used to examine the expression of ICAM-1, VCAM-1, E-selectin. The expression of MMP-9 was measured by immunohistochemistry.

RESULTJDTL, in the dose of 2 mL x kg(-1) and 4 mL x kg(-1), relieved cerebral edema (P < 0.05, P < 0.01), reduced the expressions of ICAM-1, VCAM-land E-selectin and decreased MMP-9 activity (P < 0. 05, P < 0.01) in model rats.

CONCLUSIONJiedu Tongluo injection has a protective effect on rat brain from cerebral edema induced by the injury of focal cerebral ischemia/reperfusion. The mechanism is related to that Jiedu Tongluo injection can reduce the expressions of ICAM-1, VCAM-1 and E-selectin and inhibit of MMP-9 activation in rat brain.

Isolated alkaloids from Coptis chinensis Franch. The compounds were identified as berberine, columbamine, groenlandicine, jatrorrhizine, magnoflorine, corydaldine and ferulic acid methylester. Then measured their bitter degree based on the electronic tongue and evaluated the antibacterial. The results based on the Electronic Tongue showed that berberine, columbamine, groenlandicine and jatrorrhizine have higher bitter degree than magnoflorine and corydaldine. And they also appeared better antibacterial activity on E. coli and S. aureus. The correlation coefficients between bitter degree and the two bacteria antibacterial activity were 0.983 and 0.911. So there was close relationship between the bitter degree and antibacterial activity of bitter components. Thus, it is confirmed further that bitter components are the material foundation of medicinal effectiveness of bitter herbs.

OBJECTIVETo study the effects of monocyte-macrophages (THP-1) in malignant transformation of human bronchial epithelial cells (BEAS-2B) cells induced by coal tar pitch (CTP) and the expression of TNF-α in the process of the cell malignant transformation.

METHODSBEAS-2B cells and THP-1 Cells were divided into four groups: coal tar pitch (CTP) group, benzo(a)pyrene [B(a)P] group, dimethyl sulfoxide (DMSO) group, BEAS-2B and THP-1 co-culture (co-culture group) group. Carcinogenesis model was established. The soft agar colony formation, chromosome aberrations and cell cycle tests were used to detect the cellular malignant transformation. The ELISA assay was utilized to measure the levels of TNF-α in the supernatant of CTP group and co-culture group.

RESULTSThe chromosome number abnormalities could be observed in early stage of the experiment (the 10th generation cells), which showed the increased ratio of aneuploid to polyploid, and the decreased number of diploid. The colony formation rate of co-culture group (the 20th generation cells) was 17.63‰ ± 0.97‰, which was significantly higher than that (13.94‰ ± 0.84‰) of CTP group and that (12.96‰ ± 1.62‰) of B(a)P group (P < 0.05). The proportion of S phase cells in the co-culture group was 44.49% ± 0.68%, which was significantly higher than that (38.19% ± 1.26%) of CTP group and that (36.41% ± 1.19%) of B(a)P group (P < 0.05). The TNF-α level in the co-culture group was significantly higher than that in CTP group (P = 0.001).

CONCLUSIONMonocyte-Macrophages can accelerate the malignant transformation of BEAS-2B cells induced by CTP and increase the expression level of TNF-α.
