RESUMO
Objective To clarify the inhibitory effect of Tripterine combined with Cisplatin on C6 glioma ceils and its apoptosis mechanism.Methods C6 glioma cells were treated with Tripterine,Cisplatin,or Tripterine combined with Cisplatin.CCK-8 assay was used to detect the growth inhibition rate in each group.Flow cytometry analysis was used to test the cell apoptosis rate.The expressions of apoptosis-related proteins including Bcl-2,Bax,XIAP,NF-kB were analyzed by ELISA.Results Compared with Tripterine-or Cisplatin-treated group,the inhibition ratio of cell growth in Tripterine and Cisplatin combination group was (69.76±7.28)％,which could significantly inhibit the growth of C6 glioma cells(t=23.78,P＜0.01).The apoptosis rate was significantly higher (47.75±5.63)％ in combination group than in Tripterine or Cisplatin treated group.The results of ELISA showed that the expression of Bax was significantly higher and Bcl-2,XIAP,NF-κB were obviously lower in the combination group than in Tripterine or Cisplatin treated group (t=35.27,P＜ 0.01).Conclusion The combination of Tripterine and Cisplatin significantly increases the inhibition rate on C6 glioma cells through upregulating Bax and inhibiting Bcl,XIAP and NF-kB to induce the apoptosis of C6 glioma cells.
RESUMO
Objective To investigate the applicative value of micro-surgery in the treatment of cerebral aneurysms.Methods During January 2011 to January 2013 in our hospital,90 patients with cerebral aneurysm were randomly divided into the endovascular group and the microsurgical clipping group (n =45 each).The endovascular group were treated with endovascular interventional treatment,and the patients of the microsurgical clipping group were treated with microsurgical clipping treatment.The aneurysm occlusion rate and recurrence,time of hospital stay,complications and prognosis were compared between the two groups.Results The complete occlusion rate was higher [97.8％ (44/45) vs.88.9％ (40/45) and the recurrence rate was lower 2.2％ (1/45) vs.13.3％(6/45) in microsurgical clipping group than in endovascular intervention group x2 =4.34 and 3.54,P=0.031 and 0.042),all P＜0.o5.The average time of hospital stay was longer in the endovascular intervention group than in the microsurgical clipping group [(19.3 4.4) days vs.(16.34.9) days,t 1.93,P=0.035].The good rate was higher in microsurgical clipping group than in endovascular intervention group [91.1％ (41/45) vs.77.8％ (35/45),x2=6.325,P=0.012].Conclusions Microsurgical clipping surgery can significantly raise the complete occlusion of cerebral aneurysms,reduce recurrence in patients with cerebral aneurysm,decrease the hospitalization time,and improve prognosis,which is worthy of clinical application.
