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.

Objective To assess the safety and efficacy of the transohturator tape (TOT) for surgical treatment of female stress urinary incontinence (SUI). Methods Clinical data of 206 TOT procedures for female urinary incontinence from Jan 2007 to Dec 2009 was retrospectively analyzed.Thirty-one women were identified as having mixed stress urinary incontinence.The mean age was 54.29 years(range,32-81 years),themean disease coursewas 10.31 years (range,1-40 years),and the mean follow-up time was 17.3 months (range,3-39 months).Therapeutic effects were assessed by Grouts-Blaivas outcome score.The results of the operation,complications and changes of urodynarnics were observed. Results The TOT operations were conducted under local anesthesia.The mean operative time was 23.9 min (range,16-35 min),Mean blood loss was 17.8 ml(range,15-30 ml).Short-term complications were as follows:thigh pain 14.08%,dysuria 5.83%,urinary posture change 0.97% and urinary retention 0.49%.The long-term complication rate was 0.97%,including vaginal wall defect and tape exposure in one case:the burr of tape exposure and sex life influence in one case.Long-term symptoms disappeared completely in 202 cases.The cure rate was 98.06%,and the rate of satisfaction was 100%. Conclusions Our results demonstrate that TOT procedure is a minimally invasive,safe and effective surgical treatment for stress urinary incontinence.

A novel nucleic acid amplification method,termed loop-mediated isothermal amplification(LAMP),which amplifies DNA with high specificity,efficiency,and rapidity under isothermal conditions,may be a valuable tool for the rapid detection of infectious diseases.This method employs a DNA polymerase that have activity of strand displacement DNA synthesis and a set of four specially designed primers that recognize a total of six distinct sequences on the target DNA.LAMP can amplify a few copies of DNA to 109 in less than an hour.The final products are stem-loop DNA with several inverted repeats of the target and cauliflower-like structures with multiple loops.A positive reaction would be shown as a ladder-like pattern in a gel electrophoresis analysis.Because of the advantage,the LAMP method will be widely applied to research of nucleic acid,clinical diagnosis of infectious diseases and detection of genetically modified organisms etc.

Objective To study the expression of signal transducers and activators of transcription 3(STAT3) in airway epithelial cells of asthmatic mouse model and its association with airway remodeling,explore the role of signal-transduction pathway in airway remodeling.Methods Thirty Balb/c mice were randomly divided into normal control group(n=10),asthma without intervention group(n=10) and AG490 intervention group(n=10).The mice were sensitized with ovalbumin to establish the asthmatic model.The histological changes were evaluated by HE staining,total brochial wall thickness(Wat)and smooth muscle thickness(Wam) were measured by image analysis system,the percentages of collagen deposition were detected by Masson′s trichrome staining,the expression of STAT3 in airway were detected by immunohistochemistry technique;lung tissue extracts were analyzed for phosphorylation of STAT3(p-STAT3)by Western blot.SPSS 13.0 software was used to analyze the data.Results 1.The histological changes including airway thickness,airway smooth cell proliferation and excessive collagen deposition in subepithelial aera were found under light microscope in asthmatic mice.2.The level of STAT3 and p-STAT3 in asthma without intervention group were significantly higher than those in normal control group(Pa

Objective To observe the effects of inhaled budesonide (BUD) in early phase on the airway inflammation in asthmatic mouse,and its effects on the IL-6/signal transducers and activators of transcription 3(IL-6/STAT3 )signaling pathway in airway,explore the therapeutic target of BUD.Methods Forty Balb/c mice were randomly divided into control group(n=10),asthma group(n=10),BUD group(n=10) and AG490 group(n=10).The mice were sensitized with ovalbumin to establish the asthmatic model.The histological changes were evaluated by HE staining.The levels of IL-4,IL-5 and IL-6 in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immunosorbent assay.Lung tissue extracts were analyzed for total STAT3 and phospho-STAT3(p-STAT3) by Western blot.Results 1.The levels of inflammatory cells,EOS%, IL-4,IL-5 and IL-6 levels in the BALF in BUD group were significantly lower than those in asthma group (Pa0.05).Conclusions Inhaled corticosteroid can apparently ameliorate airway inflammation in early phase in asthmatic mouse model,and it can downregulate the expressions of IL-6 and STAT3,inhibit the signal-transduction pathway of STAT3.The IL-6 /STAT3 signaling pathway of airway may be one of the potential therapeutic targets of inhaled corticosteroid.
