ABSTRACT
Objective To investigate neurological function, volume of cerebral infarction, changes of lipid peroxidation, and the intervention effect of compound angelica injection (CAI) on rats with focal cerebral ischemia injury. Methods Models of rat with cerebral ischemia were reproduced by middle cerebral artery occlusion (MCAO). All animals were randomly divided into sham-operation group, model group, CAI group, and edaravone group. 1 hour after the models were established, rats in the sham-operation group and model group received intraperitoneal injection with normal saline, while rats in CAI group and edaravone group received intraperitoneal injection with relevant medicine for continuing 7 days. Volume of cerebral infarction was detected by Tetrazole staining method, neurologic function were detected by neuroethology, and concentration of MDA in brain tissue was also detected. Results After 7-day cerebral ischemia, compared with the model group, volume of cerebral infarction in CAI group was significantly reduced (P<0.05), and the concentration of MDA was a little lower. Conclusion CAI has significant protective effects which can significantly improve neurological function, reduce volume of cerebral infarction, and alleviate the effects of lipid peroxidation of rats with focal cerebral ischemia injury.
ABSTRACT
Objective To renovate angiography in identifying portal vein anatomy during transjugular intrahepatic portosystemic shunt (TIPS) procedures,saving the time of TIPS procedures,decreasing the risk of the complications of the post-procedure.MethodsThe difference between the Wedge hepatic venography with Carbon Dioxide in 6 cases and Inferior Mesenteric artery angiography in 7 cases during TIPS procedures were compared in the identification of portal vein anatomy.The quality of images,their effects on the procedures,the complications and the recovery post-procedure were evaluated.Results Using CO2,the portal veins were opacified in all 6 cases.TIPS procedures succeeded in all cases except 1 case because of poor coagulation function.Using Inferior Mesenteric artery angiography,the portal veins were opacified in al1 7 cases.TIPS procedure succeeded in all cases except 1 case because of chronic portal occlusion.Puncture-site hematoma occurred in 1 case after TIPS procedure.ConclusionWedge hepatic venography with Carbon Dioxide is superior,safer and more convenient than Inferior Mesenteric Artery angiography in identifying portal vein anatomy during TIPS.
