BACKGROUND: Status epilepticus can result in neuronal injury.OBJECTIVE: To observe the mitochondrial ultrastructural damage and the changes of Fas, Bax and Caspase-3 expressions in hippocampal CA3 neurons of rats of different kindling, so as to provide theoretical evidence for the neuronal injury after epilepsy.DESIGN: A randomized c ntrol animal experiment.SETTINGS: Department of Neurology and Department of Anesthesiology,Qilu Hospital of Shandong University.MATERIALS: The experiments were carried out in the pathological laboratory of Shandong Academy of Medical Sciences between March and July2005. Totally 150 adult male SD rats of 260-300 g were provided by the experimental animal center of Shandong University (SCXK20030004), they were raised at room temperature and were free to the access of food and water.METHODS: The adult male Sprague Dawley (SD) rats were divided into intraperitoneal injection of kainic acid group and caudal venous injection of kainic acid group respectively ac cording to the method of random number table, and the rats were administrated by kainic acid injected intraperitoneally (12 mg/kg) and via caudal vein (10 mg/kg) respectively. Each group was divided into 5 subgroups, which were 3, 6, 24, 48 and 72 hours after status epilepticus groups respectively. Twelve successfully induced rats were selected from each subgroup, hippocampi were removed at different time points after the termination of status epilepticus, 2 were used for examination under electron microscope, 5 for the reverse transcription-polymerase chain reaction (RT-PCR) detection of Fas and Bax, and 5 for the immunohistochemical assay of Caspase-3. Another 12 rats were used as normal controls without any treatment. The materials were taken at24 hours after corresponding status epilepticus in the control group, and the specific distributions were the same as those in the subgroups. The mitochondrial structure was observed under electron microscope, the levels of Fas and Bax mRNA were detected with semi-quantitative RT-PCR, and the expression of Caspase-3 protein was determined with the immunohistochemical assay.MAIN OUTCOME MEASURES: ① Results of ultrathin section under transmission electron mcroscope; ② RT-PCR results; ③ Immunohistochemical results.RESULTS: Totally 132 rats were involved in the analysis of results. ①Mitochondrial structure under electron microscope: In the intraperitoneal injection group, the mitochondria swelled, and the neurons showed characters of apoptosis. In the caudal venous injection group, the mitochondria swelled, and accompanied by the membranous collapse, and the neurons manifested the necrosis. ② No expression of Fas and Bax was detected in the control group and caudal venous injection. In the intraperitoneal injection group, Fas expression appeared at 6 hours after status epilepticus, increased at 24 hours, reached the peak value at 48 hours, and lasted till 72 hours. ③ The Caspase-3 expressions began to increase 6 hours after status epilepticus in both the intraperitoneal injection group and caudal venous injection group(10.27±0.34, 15.21±0.34; P ＜ 0.001), and reached the peak values at 24 hours (25.36±0.47, 28.23±0.47; P ＜ 0.001); The higher expression of Caspase-3 lasted till 72 hours in the intraperitoneal injection group, but sharply decreased in the caudal venous injection group.CONCLUSION: Two different methods of administration result in different severity of mitochondrial damage and different expressions of Fas, Bax and Caspase-3, which further determines the molecular mechanisms of neuronal death.

Methods:From February 2018 to January 2022, the clinical data of 1 123 patients who underwent Starclose vascular closure device, Angio-Seal and Exoseal vascular occlusion devices and Perclose ProGlide vascular suture device at femoral artery puncture hemostasis after neuro-intervention, in the Department of Interventional Radiology (Eastern District), The First Affiliated Hospital of Zhengzhou University, were retrospectively analyzed. The patients were divided into three groups based on the intervention method: the closure group (Starclose, n=271), the occlusion group (Angio-Seal, n=327 and Exoseal, n=352) and the suture group (ProGlide, n=173). Next, the hemostatic efficacy and complications associated with the three devices were analyzed and compared. Additionally, regression analysis was conducted to identify any relevant factors that may contribute to complications. Results:Three vascular hemostatic devices demonstrated effective hemostasis and the success rate were 92.6% in the closure group (Starclose), 93.4% in the occlusion group (Angio-Seal 93.0% and Exoseal 93.8%) and 89.6% in the suture group (ProGlide). There was no statistically significant difference( χ2=3.026, P=0.388). Single or multiple complications were observed in 102 patients (9.1%), including local oozing (16 cases in the closure group, 39 cases in the occlusion group, 13 cases in the suture group), local hematoma (14 cases in the closure group, 31 cases in the occlusion group, 11 cases in the suture group), pseudoaneurysm (13 cases in the closure group, 35 cases in the occlusion group, 10 cases in the suture group), local infection (2 cases in the closure group, 3 cases in the occlusion group, 1 case in the suture group). There were no statistically significant differences ( P>0.05). Moreover, serious complications such as femoral artery occlusion, embolus shedding and permanent nerve injury weren′t observed in the three groups. Multivariate logistic regression analysis revealed that overweight ( OR=1.562,95% CI 1.023—2.385, P=0.039), femoral artery with calcified plaque ( OR=1.934,95% CI 1.172-3.189, P=0.010), combined use of multiple antiplatelet drugs ( OR=1.769,95% CI 1.103—2.839, P=0.018), use of an 8F sheath( OR=2.824,95% CI 1.406—5.671, P=0.004) and the operator′s proficiency ( OR=0.508,95% CI 0.328—0.788, P=0.002) were the independent factors influencing complications, of which the first four were identified as risk-promoting factors for complications while the operator′s rich experience and high proficiency were the protective factors. Conclusions:Three hemostatic devices demonstrate effective hemostasis and comparable rates of complications at femoral artery puncture hemostasis after neuro-intervention. Overweight, femoral artery with calcified plaque, combined use of multiple antiplatelet drugs, use of an 8 F sheath and the operator′s proficiency were independent factors influencing complications.Ojective:To investigate the efficacy and complications associated with vascular suture, closure and occlusion devices at femoral artery puncture hemostasis after neuro-intervention.
