ABSTRACT
ObjectiveTo study the clinical effect of YL-1 type hematoma puncture needle in the treatment of basal ganglion region cerebral hemorrhage.MethodsSixty-two patients with hypertensive basal ganglion region cerebral hemorrhage were treated by YL-1 type hematoma puncture needle from January 2007 to May 2011 (minimally invasive punctural evacuation group),of which,60 patients were treated by conservative treatment(conservative treatment group) as control,compared two groups of neural function defect score,hematoma clearance rate on admission,after 3 weeks treatment,and quality of life after 6 months.ResultsNeural function defect score on admission of minimally invasive punctural evacuation group was (23.6 ± 18.4) scores,while (23.4 ± 17.8) scores in conservative treatment group,the difference was not statistically significant(P ＞ 0.05).After 3 weeks' treatment,neural function defect score and hematoma clearance rate of minimally invasive punctural evacuation group was superior to conservative treatment group [ (14.6 ± 12.4) scores vs.(20.1 ± 18.4) scores,(92.3 ± 5.4)％ vs.(79.5 ± 13.8)％ ] (P ＜0.05 ).After 6 months' treatment,the good rate of quality of life in minimally invasive punctural evacuation group was 81.7％(49/60),which was significantly increased compared with that of conservative treatment group [67.2％ (39/58)] (P ＜ 0.05).ConclusionsThe minimally invasive punctural evacuation in the treatment of basal ganglion region cerebral hemorrhage has small invasion,better prognosis,effective and fast decompression of intracranial hematoma,reducing disability rates,improvement of the quality of life,which could be a beneficial complement for traditional therapies.
ABSTRACT
ObjectiveTo investigate the role of electroencephalogram (EEG) examination in the prognosis evaluation of patients with severe craniocerebral injury.MethodsFifty-seven patients with severe craniocerebral injury were selected as study subjects and their clinical data were analyzed retrospectively.All the patients got EEG examination,and the relationships between EEG grading and Glasgow coma scale (GCS) score,the prognosis of outcome were analyzed.ResultsThe EEG of 57 patients within 24 h after hospitalization were all abnormal.There was significantly negative correlation between EEG grading and GCS score (r =-0.742,P ＜0.05).EEG grading was significantly positively correlated with the prognosis of outcome (r =0.730,P＜ 0.05).ConclusionsEEG examination and EEG grading can evaluate the prognosis of patients with severe craniocerebral injury.It provides reference for clinical treatments.
ABSTRACT
Objective To assess the safety and efficiency of Angioseal device in patients undergoing percutaneous femoral artery puncture in brain angiograph or interventional therapy. Methods A prospective trial was carried out in 128 patients undergoing brain angiograph and interventional therapy,in which 93undergoing brain angiography and 35 interventionsl therapy. All patients were divided into pure compression group by manual compression (83 cases) and vascular blocking group by Angioseal device (45 cases)according to different hemostatic measures. Results In angiography, hemostasis time of vascular blocking group and pure compression group was (1.8 ±0.8) min and(20.2 ±9.4) min (P＜0.01 ),ambulation time was (3.8 ± 0.8) h and (19.4 ± 2.2) h (P ＜ 0.01). In interventional therapy,hemostasis time of vascular blocking group and pure compression group was (2.0 ± 1.1) min and (24.5 ± 10.3) min (P ＜ 0.01), ambulation time was (4.3 ± 1.5) h and (24.3 ± 3.2) h (P＜ 0.01). Pure compression group had higher complication rate (such as bleeding,hematoma,skin ulceration and blister) than vascular blocking group (P＜0.01).Conclusion Angioseal closure device is safe, efficient and easy to use.
ABSTRACT
Objective To investigate the dynamical changes of Rho kinase in the cerebrospinal fluid (CSF) and its relationship with cerebral vascular spasm CVS. Methods CSF were collected on the ist, 3rd, 7th, 10th and 14th day after subarachnoid hemorrhage. The expression of Rho-kinase mRNA in CSF was determined by RT-PCR. The expression of endothelin-1 in CSF was determined by radioimmuno-assay. TCD was used to measure the velocity of the cerebral artery. Results The levels of ET-1 and Rho-kinase mRNA in CSF were re-markably increased on the 3rd day, and reached at the peak on the 7th day after subarachnoid hemorrhage, which were significantly higher than those without CVS. Conclusion There is a positive correlation between the level of Rho-kinase mRNA and ET-1 in CSF. Rho-kinase may participate in the development of CVS.
ABSTRACT
Objective To study the morphological characteristics of blood-tumor barrier(BTB)model of glioma in vitro. Methods After C 6 glioma cells/endothelia ECV 304 co-cultured mixed or in Transwell or on both sides of membrane of Transwell,the morphological characters of fenestra of endothelial cells,the junction between ECV 304 cells,the interface between C 6 cells and ECV 304 cells,and perivascular-end-feet of C 6 cells were observed under transmission electron microscope(TEM)and scanning electron microscope(SEM),and compared to BTB in 4 cases with human brain glioma. Results ECV 304 cells grown to confluence were not fenestrated,but with fomation of tight junction between ECV 304 cells after co-cultured with C 6 cells mixedly,in Transwell or on both sides of membrane of Transwell;It was not found that pseudopodia from C 6 cells as co-cultured in Transwell reaching into pore of Transwell;C 6 cells co-cultured on both sides of membrane of Transwell often sticked out to the ECV 304 cells,but with no pseudopodia from C 6 cells surrounded ECV 304 cells of penetrated the endothelia clefts.Perivascular-end-feet of C 6 cells were not integrant.These characters were similar to BTB in human brain glioma.Conclusion C 6 glioma cells/endothelia cell ECV 304 co-cultures on both sides of membrane of Transwell may simulate the morphological characters of BTB in vivo in some degree.;
