Objective To explore hematoma piercing attract joint hematoma clearance to bone valves decompression technique in hematoma volume,skull,pressure high blood pressure brain hemorrhage treatment,and to further explore hypertension brain hemorrhage of reasonable surgery. Methods Hematoma in relatively large quantities of high intracranial pressure in hypertensive cerebral hemorrhage patients were randomly divided into experimental group and control group,and patients in the experimental group were implemented early hematoma puncture to attract a joint hematoma decompressive craniectomy treatment,and the control group were implemented the traditional hematoma de-compressive craniectomy treatment. The prognosis of the two groups were compared. Results The two groups were followed up for 6 months,and evaluated by ADL grade,between the two groups was statistically significant difference in ADL classification( P<0.01). Conclusion In the hematoma volume larger, high intracranial pressure in hypertensive cerebral hemorrhage in the surgical treatment of patients,the early line to attract a joint hematoma puncture decompressive craniectomy was a reasonable and feasible surgical method which can improve these patients prognosis.

Objective To explore the reasons and the treatment counter-measures for secondary intracranial hemorrhage happens in the intracranial tumor craniotomy. Methods Retrospectively analyzed the clinical data of 15 patients with intracranial tumor who suffered secondary intracranial hemorrhage intraoperation. Summarized the tumor characteristics and the situation of corresponding vessels confined by second operation. Results In these 15 cases,the rank of course of disease was 6.5 months to 2 years, mean 1.2 years. The size of the tumor was big with diameter 4.62 ～5. 82cm,mean 5. 12cm,and the tumor was deep surrounding by large range edema,which led to intracranial hypertension. The emissary vein,bridging vein and cortical draining vein were considered as the corresponding vessels for ' secondary intracranial hemorrhage during the second operation carried out for all 15 cases. There wsa no death cases in this research and all patients recovered the nomal ability for self-caring after 3 months following up. Conclusion Sudden drawdown of intracranial pressure and perfusion pressure breakthrough of local vessels had relationship with secondary intracranial hemorrhage during craniotomy for intracranial tumor. Accurate judgement for the occurrence of secondary intracranial hemorrhage intra-operation and quickly taking the effective corresponding measures was the important strategy for prognosis improving for these patients.

Objective To explore the changes of brain-derived neurotrophic factor(BDNF) after repeated febrile seizures (FS).Methods Fifty-one male SD rats were divided into 3 groups randomly: normal group (NC group,n=14) ,hyperthermic group (HC group,n=19),FS group(n=18). FS were induced by hot water bath.The level of BDNF in hippocampus homogenate were measured by enzyme linked immunosorbent assay (ELISA) and the expression of BDNF were measured by immunohistochemistry.The apoptosis of the brain cells were determined by terminal deoxynucleotide mediated nick end labeling (TUNEL).The results were analysed with the software of SPSS 13.0.Results The level of BDNF in hippocampus in FS group(89.90?12.51) ng/g was significantly higher than that in NC group(54.43?18.92) ng/g and HC group(64.09?15.03) ng/g (Pa

Objective To observe the expressions of nuclear factor-?B(NF-?B)in brain tissue of rats with repeated febrile seizures(FS)and explore its significance in brain injury of rats with FS.Methods Fifty-one male SD rats were divided into 3 groups according to random number method:normal group(n=14),hyperthermic group(n=19),FS group(n=18).FS models were induced by placing rats in warm bath;the rats without FS after warm-bath were assigned as hyperthermic group ;the normal controls received no treatment.The expression of NF-?B was measured by immunohistochemistry.The apoptosis of brain tissue was determined by terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling(TUNEL).SPSS 13.0 software was applied for statistical treatment.Results In FS group,the number of the NF-?B positive neuron increased much more than that of hyperthermic group and normal group(Pa

Objective To explore the change of somatostatin(SS)in brain areas of juvenil rats with repeated febrile seizures(FSs)and hyparthermia.Methods Fifty-one male SD rats were divided randomly into 3 groups:normal group(NC group,n=14),hyperthermic group(HC group,n=19)and febrile seizure group(FS group,n=18).FS were induced by placing rats in a bath of water.The expressions of SS in DG,CA3,CA1 and CTL were measured by immunohistochemistry.The level of SS in hippocamps of these rats were determined by radioimmunoassay.Results The results of immunohistochemistry shew in HC group,the number of the SS positive neuron were increased in DG(21.10?2.51),CA3(10.60?2.41)in FS group,which was less than that in NC group(10.50?2.12,6.90?2.02),there was no difference in CA1 and CTL.The result of Radioimmunoassay:the level of SS in hippocampus in HC group[(53.74?7.56)ng/g]was higher than that in FS group[(39.54?7.74)ng/g](P0.05).Conclusion There is different change of somatostatin content in some brain areas of rats with repeated febrile seizure,which suggest that SS can increase the affectivity of seizure and promote the seizure.

Hypoxia occurs in chronic and acute vascular diseases and tumor formation. The ability of tumor cells to maintain a balance between an adaptation to hypoxia and cell death is regulated by a family of transcription factors called hypoxia-inducible factor 1 (HIF-1). Tumor hypoxia mediated by HIF-1 would facilitate the likelihood of resistance to chemotherapy and radiotherapy, proliferation, metastasis and the invasive potential; all of which culminate in a decrease in patient survival. And HIF-1 alpha subunit decides the activity of HIF-1, which is regulated by oxygen. So understanding the role of HIF in signal pathway, drug resistance mechanism and its feature is crucial for developing novel anticancer therapies. In recent years, more attentions have focused on HIF-1 alpha inhibitors. It is expected that development of more potent and selective HIF inhibitors will provide an effective treatment of cancer and other HIF-related diseases. So we will focus on the biological characteristics and mechanism of HIF-1 to review currently studied HIF-1 inhibitors.

Objective To discuss the diagnosis and treatment of superior sagittal sinus thrombosis.Methods The early diagnosis and treatment of superior sagittal sinus thrombosis was induced and summarizd,7 cases in our hospital treated from 2005.6 to 2008.9.were analyzed.Results In this investigation,3 cases were puerperal women,and the other 4 had no special medical history.Brain edema of difference degree was found in all cases on CT scans,including sulcus (7 cases),compression of cistern(5 cases) or even disappeared of cistern(2 cases).CT scanning also revealed dense triangle in 2 cases,multiple small encephalomalacia focus of frontal lobe lesions in 3 cases,and sub-arachnoid hemorrhage(SAH) in 2 cases.The digital subtraction angio-grapby(DSA) also was underwent,of 2 superior sagittal sinus not seen,of 4 appear unevenness,of 7 Arterio-venous circulation delayed and of 5 collateral circulation vasodilatation.After treatment,the clinical symptoms and signs of all patients were improved.All of them could be self-supporting.Followed up for 3 years,the mortality was 0,and no one cerebral hemorrhage again.Conclusion The early diagnosis and treatment of superior sagittal sinus thrombosis could reduce the morbidity and mortality, also could improve prognosis.Especially for the one without cerebral hemorrhage,using heparin at the beginning was an effective and safe way.
