ABSTRACT
OBJECTIVE:To study the effects of salvianolate on the expression of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9(MMP-9)in lung tissue of mice with lung cancer. METHODS:C57BL/6 mice were randomly divid-ed into model group (normal saline),positive control group (cyclophosphamide 50 mg/kg) and salvianolate low-dose,medi-um-dose and high-dose groups(20,40,80 g/kg)with 10 mice in each group. They were ig 1 000 mg/kg urethane,twice a day, for consecutive 4 weeks to establish lung cancer model. After modeling,they were given relevant medicine intragastrically once a day for consecutive 14 d. Mice behaviors,symptoms,body weight,tumor inhibition rate,spleen index,thymus index,and the ex-pressions of VEGF and MMP-9 in lung tissue among groups were compared. RESULTS:The activity of mice in model group disap-peared,dull coat color,preferred crowding together;the above-mentioned phenomenon improved in positive control group and sal-vianolate different dose groups. The body weight of mice in positive control group,salvianolate low-dose group,medium-dose group and high-dose group were(21.01±2.95)g,(20.89±3.14)g,(21.03±3.02)g,(21.24±3.17)g;and the tumor inhibition rates were(41.12±15.42)%,(36.92±10.42)%,(39.41±12.39)% and(37.19±10.39)%;compared with model group,spleen index,thymus index,and the expressions of VEGF (except for positive control group) and MMP-9 in other 4 groups decreased (P<0.05). CONCLUSIONS:Salvianolate shows obvious inhibitory effects on mice with lung cancer,which may be related to in-hibiting expressions of VEGF and MMP-9 in lung tissue.
ABSTRACT
<p><b>OBJECTIVE</b>To study the influence of Aconiti Lateralis Radix Praeparata on asthenia cold syndrome rats with whole genome gene expression of liver by gene chip technique.</p><p><b>METHOD</b>The asthenia cold syndrome rat models were established by administering traditional Chinese medicine raw Gypsum Fibrosum, Gentianae Radix, Phellodendri Chinensis Cortex and Anemarrhenae Rhizoma. After treated with Aconiti Lateralis Radix Praeparata, the rats' liver gene expressions were detected using gene chip. Differential expression genes were screened for gene function annotation, and some genes were selected to check the accuracy of the results by RT-PCR.</p><p><b>RESULT</b>Compared with the asthenia cold model group, the asthenia cold treatment group showed 212 differential expression genes, mainly involving function of immune response and oxidoreductase activity.</p><p><b>CONCLUSION</b>Aconiti Lateralis Radix Praeparata is proved to have an effect on up-regulating immune response-related genes and oxidizing oxidoreductase activity-related genes of asthenia cold syndrome rats and may be a molecular mechanism for classical warm-nature medicine Aconiti Lateralis Radix Praeparata in warming meridians and dissipating cold.</p>
