RESUMO
OBJECTIVE： To study the effects and mechanism of Le’ermai capsule on oxidative stress injury in the cerebral cortex of cerebral ischemia-reperfusion injury rats. METHODS： Totally 65 rats were randomly divided into sham operation group （normal saline）， model group （normal saline）， positive control group （Naoxintong capsule， 3.40 g/kg）， Le’ermai capsule high-dose and low-dose groups （0.37， 0.18 g/kg）， with 13 rats in each group. Except that sham operation group received sham operation， and middle cerebral artery occlusion/reperfusion （MCAO/R） model was induced by suture-occluded method. 24 h after modeling， they were given relevant medicine intragastrically， once a day， for consecutive 7 d. 2 h after last administration， cerebral ischemic area was determined by TTC staining. The pathological changes of cerebral tissue were observed by HE staining. The protein expressions of HO-1， SOD1， SOD2 and Nrf2 in cerebral cortex were detected by Western blot assay. RESULTS： Compared with sham operation group， the area of cerebral ischemic was increased significantly in model group（P＜0.05）， interstitial edema was serious， inflammatory cell infiltration increased significantly； and the protein expression levels of HO-1 and SOD1 in cortex tissue were significantly increased （P＜0.05）， and the protein expression levels of SOD2 and Nrf2 were significantly decreased （P＜0.05）. Compared with model group， the area of cerebral ischemic area of Le’ermai capsule high-dose and low-dose groups were significantly decreased （P＜0.05）. The interstitial edema， inflammatory cell infiltration and microcytes proliferation were decreased. The protein expression levels of HO-1， SOD1， SOD2 and Nrf2 in the cerebral cortex tissue were significantly increased （P＜0.05）. CONCLUSIONS：Le’ermai capsule can improve cerebral ischemia/reperfusion injury to certain extent， and which may be associated with up-regulating the protein expression of antioxidant factors HO-1， SOD1， SOD2 and Nrf2 in the cortex.

RESUMO
Objective:To explore the effects of Bufalin on the growth and proliferation of human glioma cells U251. Methods:Methyl thiazolyl tetrazolium(MTT)assay was used to detect the effect of Bufalin on the proliferation of human glioma cells U251. An in-verted microscope was used to observe the changes of cell number,morphology and activity. AnnexinV/ PI was used to measure the in-duction of cell apoptosis caused by Bufalin. Results:Bufalin at different concentrations(0. 001 - 10. 0μmol·L - 1 )inhibited the pro-liferation of U251 cells in a dose and time-dependent manner. Compared with that of the control group,the apoptosis rate of Bufalin group was increased significantly(P < 0. 01). Conclusion:Bufalin can inhibit the growth and proliferation of U251 cells in a dose and time-dependent manner,and induce the apoptosis of U251 cells.
RESUMO
Triptolide, a compound extracted from the traditional Chinese medicine preparation of Tripterygium wilfordii Hook F., has been reported to have anti-inflammatory and anti-cancer activities. However, its effect on ovarian cancer invasion is unknown. We observed that MMP7 and MMP19 expression increased in ovarian cancer tissue. Triptolide treatment inhibited the migration and invasion of ovarian cancer cells SKOV3 and A2780 at the concentration of 15 nM. We also observed that triptolide suppressed MMP7 and MMP19 promoter activity in a dose-dependent manner, down-regulating the expressions of these promoters on mRNA and protein level. Moreover, triptolide enhanced E-cadherin expression in ovarian cancer cells. In vivo, triptolide inhibited tumor formation and metastasis in nude mice, and suppressed MMP7 and MMP19 expression; it also enhanced E-cadherin expression in tumor in a dose-dependent manner. Over expression of MMP7 and MMP19, or suppression of E-cadherin expression partially abolished the inhibitory effect of triptolide on invasion of ovarian cancer cells. To summarize, triptolide significantly inhibited the migration and invasion of ovarian cancer cells by suppression of MMP7 and MMP19 and up-regulation of E-cadherin expression. This study shows that triptolide is a good candidate for the treatment of ovarian cancer and reduction of metastasis.
