Objective To evaluate the efficacy of electrocorticographic (ECoG) monitoring and the application of different surgical approaches in the surgical treatment of solitary supretentorial cavernous malformations with secondary epilepsy.
Methods This study enrolled a consecutive series of 36 patients with solitary supratentorial cavernous malformations and secondary epilepsy who underwent surgery with intraoperative ECoG monitoring in the Department of Neurosurgery between January 2004 and January 2008. The patients were composed of 15 males and 21 females, aged between 8 and 52 years (mean age 27.3±2.8 years) at the time of surgery. Epilepsy history, the type of epilepsy at the presentation, lesion location, the incidence of residual epileptiform discharges, and postoperative outcomes were evaluated.
Results Histopathological examination indicated cavernous malformations and hippocampal sclerosis in 36 and 5 cases, respectively. Neuronal degeneration, glial cell proliferation, and neurofibrillary tangles were found in all the resected cerebral tissues of extended lesionectomy of residual epileptic foci. Lesionectomy, anterior temporal lobectomy, anterior temporal lobectomy plus cortical thermocoagulation, extended lesionectomy, extended lesionectomy plus cortical thermocoagulation were performed in 4, 4, 1, 14, and 13 cases, respectively. Residual epileptiform discharges were captured in 9 out of the 14 patients who had additional cortical thermocoagulation. According to Engle class for postoperative outcomes, 27 cases were class I (75.00%), 5 were class II (13.89%), 2 were class III (5.56%), and 2 were class IV (5.56%), thus the total effective rate (class I+class II) was 88.89%. Neither of epilepsy history, the type of epilepsy, and the location of cavernous malformation was significantly related to outcomes (P>0.05). A significant relationship was found between the incidence of residual epileptiform discharges and outcomes (P=0.041).
Conclusions Intraoperative ECoG monitoring, the application of different surgical approaches, and the resection of residual epileptic foci could produce good result in the surgical treatment of supratentorial cavernous malformation with secondary epilepsy. Postoperative residual epileptiform discharges could be a useful predictor for evaluating the outcomes.

Atropa belladonna is a medicinal plant and main commercial source of tropane alkaloids (TAs) including scopolamine and hyoscyamine, which are anticholine drugs widely used clinically. Based on the high throughput transcriptome sequencing results, the digital expression patterns of UniGenes representing 9 structural genes (ODC, ADC, AIH, CPA, SPDS, PMT, CYP80F1, H6H, TRII) involved in TAs biosynthesis were constructed, and simultaneously expression analysis of 4 released genes in NCBI (PMT, CYP80F1, H6H, TRII) for verification was performed using qPCR, as well as the TAs contents detection in 8 different tissues. Digital expression patterns results suggested that the 4 genes including ODC, ADC, AIH and CPA involved in the upstream pathway of TAs, and the 2 branch pathway genes including SPDS and TRII were found to be expressed in all the detected tissues with high expression level in secondary root. While the 3 TAs-pathway-specific genes including PMT, CYP80F1, H6H were only expressed in secondary roots and primary roots, mainly in secondary roots. The qPCR detection results of PMT, CYP80F1 and H6H were consistent with the digital expression patterns, but their expression levels in primary root were too low to be detected. The highest content of hyoscyamine was found in tender stems (3.364 mg x g(-1)), followed by tender leaves (1.526 mg x g(-1)), roots (1.598 mg x g(-1)), young fruits (1.271 mg x g(-1)) and fruit sepals (1.413 mg x g(-1)). The highest content of scopolamine was detected in fruit sepals (1.003 mg x g(-1)), then followed by tender stems (0.600 mg x g(-1)) and tender leaves (0.601 mg x g(-1)). Both old stems and old leaves had the lowest content of hyoscyamine and scopolamine. The gene expression profile and TAs accumulation indicated that TAs in Atropa belladonna were mainly biosynthesized in secondary root, and then transported and deposited in tender aerial parts. Screening Atropa belladonna secondary root transcriptome database will facilitate unveiling the unknown enzymatic reactions and the mechanisms of transcriptional control.

Objective Toinvestigatetheriskfactorsforleukoaraiosis(LA)inpatientswithlarge arteryatherosclerosis(LAA).Methods Theclinicaldata(age,sex,hypertension,diabetes,smoking, serum lipid level,hyperhomocysteinemia,and numbers of stenosis or occluded cerebral arteries)of 312 patients with LAA classified by the modified stop stroke study trial of Org 10172 in acute stroke treatment (SSS-TOAST ) were analyzed retrospectively. The age-related white matter changes (age related white matter changes,ARWMC)scale was used to evaluate LA. All the 312 patients were divided into non-LA group(n=72)and LA group(n=240)according the T2 weighted magnetic resonance imaging (MRI) and fluid attenuated inversion recovery(FLAIR)sequence,and 3 groups according to the (age-related white matter changes,ARWMC)scores:mild LA,moderate LA,and severe LA groups. The patients with multiple risk factors were analyzed by the univariate and multivariate Logistic regression analyses. Results (1)Of the 312 patients with LA,227 were males (72. 8%). Their average age was 64 ± 11 years,and 240 of them (76. 9%)had LA. Multivariate Logistic regression analysis showed that age (OR,2. 911,95%CI 1. 647-5.146,P=0. 000),hypertension (OR,2. 583,95%CI 1. 373-4.857,P<0. 01),diabetes (OR,1. 882, 95%CI 1. 058-3. 348,P <0. 05),the numbers of stenosis or occlusion arteries (OR,1. 851,95%CI 1.018-3. 367,P<0. 05),and lacunar infarction (LI)(OR,1.493,95%CI 1. 202-1. 853,P<0. 01)were the risk factors for LA. (2)The comparison of the clinical data in patients with different severity in the LA group found that there were significant differences in age,hypertension,diabetes,the numbers of stenosis or occlusionarteries,andLIamongthe3groups(allP<0.05).Conclusion Age,hypertension,diabetes, the numbers of stenosis or occlusion arteries,and LI are the independent risk factors for patients with LAA,and it is associated with the severity of LA.

Objective To investigate the therapeutic effect of surgical management on patients with secondary epilepsy under the monitoring of cortical electrocorticography (ECoG). Methods Eighty-four patients with secondary epilepsy, admitted to our hospital from September 2004 to January 2008, were chosen; intraoperative ECoG monitoring was performed to locate the epileptic foci before the resection of the primary lesion. After the resection of primary lesion, resection of epileptic foci, enlarged resection of epileptic foci, cortical thermocoagulation, anterior temporal lobectomy,amygdalohippocampectomy and anterior callosotomy were performed, respectively, in different patients according to the clinical manifestations of seizures, and the locations of lesions and epileptic waveform discharges detected by intraoperative ECoG monitoring. Results The epileptic waveform discharges in 84 patients were noted before the resection of primary lesion. The epileptic waves were found in 80patients at the peripheral areas of the primary nidus under immediately postoperative ECoG monitoring,with a relevance ratio reaching 95.24%; after the resection of residual cortical zone with epileptic wave discharges, epileptic wave disappeared on immediately postoperative ECoG in 13 patients whose lesion located in nonfunctional area; normal signals were noted in 60 of the 67 patients performed cortical thermocoagulation whose cortical zone with epileptic wave discharges were located or neighbored in functional area, and good outcomes under the immediately postoperative ECoG monitoring were noted in the other 7 patients performed thermocoagulation combined with anterior callosotomy and/or amygdalohippocampectomy. The follow-up studies for 10 months to 4 years showed that grade Ⅰ in 56patients (66.67%), grade Ⅱ in 21 (25.00%), grade Ⅲ in 4 (4.76%) and grade Ⅳ in 3 (3.57%) according to the Engle standard of curative effect were achieved; the total effective rate was 96. 42%. Conclusion ECoG monitoring can significantly improve the efficiency of surgical management of secondary epilepsy.

OBJECTIVETo study the genetic pathogenesis of myasthenia gravis (MG) caused by cytotoxic T lymphocyte associated antigen-4 (CTLA-4) gene polymorphisms and regulation function of transcription factor.
METHODSELISA assay was used to determine the expression level of serum sCTLA-4 in MG. Four single nucleotide polymorphisms (SNPs) of CTLA-4 at exon 1 +49, promoter -318, -1661, -1772 were analyzed by restriction fragment length polymorphism (RFLP). Transcription factor nuclear factor 1(NF-1) and c/EBPbeta binding site were confirmed by chromatin immunoprecipitation(CHIP) assay.
RESULTSIt was found that the frequencies of the GG+49 genotype and G+49 allele are higher in MG patients with thymoma than those in patients of thymic hyperplasia and normal thymus subgroups. T/C-318 is not correlated with MG. The frequency of CT-1772 genotype is significantly higher in MG patients, especially in MG patients with thymoma, when compared with that in healthy controls. Meanwhile, the frequency of the G-1661 allele and GG-1661 genotype is lower in MG patients. Linkage disequilibrium (LD) between each SNPs in promoter -1772, -1661, -318 and coding sequence 1 (CDS 1) +49 is apparent. sCTLA-4 levels in patients' sera are correlated with the haplotype and genotype. T/C-1772 and A/G-1661 SNPs change the sequence of transcription factor NF-1 and c/EBPbeta binding sites. DNA variants lose site-specific binding activity of transcription factor regulated by lectin ConA and PHA.
CONCLUSIONThere are strong positive linkages among four SNPs. C/T-1772 and A/G-1661 polymorphisms can result in inefficient transcription of CTLA-4 gene. T>C-1772 mutation also affects gene splicing. These SNPs may constitute a factor of susceptibility to disease.

Objective To study the surgical treatment and effects of the lesions in the third ventricle. Methods The data of 15 patients with third ventricular lesion, accepted surgical treatment were retrospectively analyzed. The lesions were removed through transcallosal approach in 11 patients, frontal trans-cortical approach in 2 and trans-terminalis approach in 2,respectively. Postoperative radiotherapy was performed in 5 and chemotherapy in 2. VP shunt was performed in 1. Results The lesions were total-resected in 8 (53.3%), subtotal-resected in 5 (33.3%) and partial-resected in 2 (13.3%) with 1 postoperative death. The hydrocephalus were resolved in all cases. With a follow-up of 3 to 12 months, all the 14 patients recovered without obvious neurological deficits. Conclusion Proper microsurgical approach and perfect surgical skills are the keys to high resection and good prognosis. And postoperative radiotherapy or chemotherapy may be helpful in improving the outcome
