ABSTRACT

Objective To compare the effect of Solitaire AB and Enterprise stent-assisted endovascular embolization of intracranial wide-necked aneurysms. Methods The clinical data 218 patients with intracranial aneurysm treated with Solitaire AB stent or Enterprise stent in Guangdong General Hospital from January 2012 to December 2014 were analyzed retrospectively. Seventy patients were treated with Solitaire AB stents and 148 were treated with Enterprise stents. They were followed up after procedure (2 months to 2 years). The Raymond grade and the modified Rankin scale (mRS)scores were used to compare the efficacy of the 2 kinds of stents. Results There were no significant differences in patients before procedure in the Hunt-Hess grade (Z = 1. 550,P = 0. 121),Fisher grade (Z =1. 537,P =0. 124),aneurysm size (Z =0. 192,P =0. 848),and position (χ2 = 0. 337,P = 0. 736)between the 2 stent groups,while there were no significant differences in patients after procedure in the instant Raymond grade (Z = 0. 682,P = 0. 495), follow-up Raymond grade (Z = 0. 206,P =0. 837),and mRS score (P =0. 662)between the 2 stent groups. Further multivariate Logistic regression analysis showed that the stent type (Solitaire AB stent or Enterprise stent),Raymond grade follow-up grade (OR,0. 029 ,95% CI 0. 126 - 0. 199,P = 0. 661 ),and postoperative mRS score (OR,2. 000,95% CI 0. 204 - 19. 603,P = 0. 552)had no influence on the prognosis. Conclusions In the assisted embolization of intracranial wide-necked aneurysms using the Solitaire AB and Enterprise stents,the effects of both stents are good in the assisted embolization of intracranial wide-necked aneurysms.

ABSTRACT

Objective We investigate lipid peroxidation of compressed myeloid tissue at early stage after decompression of chronic compressive spinal cord injury.Method SOD and MDA of compressed myeloid tissue are measured respectively before compression,before decompression and 3h after decompression.Result Increased MDA while decreased SOD of compressed myeloid tissue at 3h after decompression than before decompression.Conclusion The increased lipid peroxidation of compressed myeloid tissue at early stage after decompression of chronic compressive spinal cord injury.It is possible that it was resulted from ischemical reperfusion injury.

ABSTRACT

Objective To observe the effect of early mild hypothermia on the opening of tight junction of cerebral endothelial cells following traumatic brain injury in order to illustrate possible mechanism of low permeability of blood brain barrier (BBB) treated by mild hypothermia. Methods A total of 90 Wistar rats were randomly divided into normothermia control group (n=10),normothermia injury group (n=40) and mild hypothermia group (n=40). The opening state and its extent of tight junction were observed using lanthanum trace labeling with electron microscope. At the same time,water content of cerebral tissue at different phases in normothermia injury group and mild hypothermia group was measured by means of dry-wet weight and analyzed statistically. Results The tight junction was under preliminary opening three hours after trauma and reached the maximum opening within 24-48 hours after trauma,lasting for 72 hours in the normothermia injury group. However,slight opening appeared only in the mild hypothermia group. Water content of cerebral tissue in the mild hypothermia group lessened obviously in contrast to that in the normothermia injury group,with significant difference 3,24 and 72 hours after trauma ( P
