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 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 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.

OBJECTIVETo explore the intervention of Fagopyrum cymosum (Trev.) Meisn alcohol extract (FAE) on defecation function and motor functions of isolated colons of diarrhea-predominant irritable bowel syndrome (D-IBS) rats and to study its underlying mechanism.

METHODSThe D-IBS rat model was established by neonatal pups maternal separation (NMS) combined with intracolonic infusion of acetic acid (AA). Adult IBS rats were randomly divided into the pre-intervention control group (n = 10, with no gastrogavage), the normal saline control group (n = 10, administered with normal saline by gastrogavage), the pre-treatment model group (n = 8,with no gastrogavage),the normal saline model group (n = 8, administered with normal saline by gastrogavage), the low dose FAE group (n = 8, administered with 6 g/kg FAE by gastrogavage), the high dose FAE group (n = 8, administered with 24 g/kg FAE by gastrogavage), and the Pinaverium Bromide group (n = 8, administered with 0.02 g/kg Pinaverium Bromide by gastrogavage). All medication was performed once daily for 2 weeks. The abdominal withdrawal reflex (AWR) was employed to evaluate the visceral hypersensitivity; their loose and watery stool grade was assessed by Bristol scores for stool consistency; and their fresh feces weight was calculated. In vitro effect of different concentrations of FAE and Pinaverium Bromide (0.02 μg/mL) on spontaneous contraction and spasmodic contraction induced by acetylcholine (Ach) in rats' isolated colon were observed and the influence on the intestinal calcium channel was evaluated.

RESULTSCompared with the pre-intervention control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the pre-intervention model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased drastically (P < 0.01). Compared with the normal saline control group, the pain pressure threshold and the maximum tolerance pressure decreased significantly in the normal saline model group (P < 0.05), and the loose and watery stool grade and fresh feces weight increased markedly (P < 0.01). Compared with the normal saline model group, the pain pressure threshold of 24 g/kg FAE and Pinaverium Bromide group significantly increased (P < 0.05). The loose and watery stool grade and fresh feces weight decreased obviously in the low dose FAE group, the high dose FAE group, and the Pinaverium Bromide group (P < 0.05). FAE (30, 100, 300, 1,000, and 3,000 μg/mL) and Pinaverium Bromide could significantly inhibit spontaneous contraction of isolated intestines (P < 0.05, P < 0.01), and FAE (30, 100, and 300 x 10(-6) g/mL) could remarkably inhibit their spasmodic contraction and contractile tension induced by Ach and Ca2+ respectively (P < 0.05, P < 0.01) in a concentration-dependent manner. Pinaverium Bromide also could significantly inhibit Ach and Ca2+ induced contraction.

CONCLUSIONEffective components of FAE improved the defecation function and inhibited enterospasm induced intestinal hyperactivity in IBS model rats via antagonizing calcium channel competitively and inhibiting colonic motility dose-dependently.
