Objective To explore the effect and adverse reaction of topiramate(TPM) on treating Lennox-Gastaut syndrome(LGS)(including therapeutic alliance or single ). Methods Twenty-four cases with LGS whose attacks could not be controlled by re-(gular) therapy were selected.TPM was gradually increased from low dosage till its showing effect or untolerant adverse reaction.Results Two cases were excluded because of adverse reaction and increase of attacks. The remained cases were followed up from 6 months to 15 months (average: 9 months). The total effective rate was 82.6%, 11 cases accounting for 45.8% free of attack. The tonic-clonic seizure reduced more than 50% accounting for 82.2%, the full control accounting for 66.7%. The myoclonic seizure reduced more than 50% accounting for 81.8%,the full control accounting for 58.8%.The atypical absence seizure reduced more than 50% accounting for 81.8%, the full control accounting for 63.6%. The maximum effect occurred about 2-40 weeks following TPM used, the dosage about 2-10 mg/(kg?d).The adverse reaction included anorexia (8 cases), language disorder (5 cases), drowsiness (4 cases), decrease of anamnesis (3 cases), weight loss or unchanged(3 cases), inattention (3 cases), depression (3 cases), mental bradypraxia (2 cases ), skin damage (1 case), stupor (1 case), gross hematuria(1 case).The hepatic and renal function were normal during therapy. Conclusion TPM is a new, broad-spectrum, effective and safe antiepileptics drug on treating LGS.

Objective To explore the clinical significance of abnormal spindle wave in the central nervous system.Methods Eighty-four cases of central nervous system disease were retrospectively analyzed.Results The attenuation and disappearance of electroencephalogram spindle wave cue marked brain structural damage, the region of abnormal electroencephalogram spindle wave was similar to that of brain computer tomography showing.Conclusion Abnormal electroencephalograph spindle wave always indicates intracranial disease, which may play an important role in the decisive diagnosis and the judgment of prognosis of the disease.

Background and purpose:More than 70 percent of ovarian cancer patients were diagnosed in the advanced stage. Currently the 5-year disease free survival (DFS) of stageⅢC-Ⅳovarian cancer patients wsa about 10 percent after first line chemotherapy. This study aimed to improve the 5-year DFS by three-step chemotherapy according to the mechanisms of ovarian cancer biological characteristics, cytodynamics and pharmacology. Methods:In arm A, the patients received three-step chemotherapy after primary debulking surgery, step one with paclitaxel plus carboplatin (TC regimen), every 3 weeks for 6 to 8 cycles;step two with etoposide plus cyclophosphamide, every 4 weeks for 6 cycles;step three wit carboplatin plus cyclophosphamide every eight weeks for six cycles. In control arm B, we retrospectively analysed 51 cases withⅢC-Ⅳstage ovarian cancer, who had completely response after standard chemotherapy with six to eight cycles of TC after primary surgery during 2007. We compared the 5-year DFS between the two arms. Results:The 5-year DFS of 15 cases in arm A was 80%(12/15), which was signiifcantly higher than that of arm B (5.9%, 3/51, P<0.01). Conclusion: The three-step chemotherapy after optimal debulking surgery in stageⅢC-Ⅳ can improve the 5-year DFS. This regimen is high efficacy, mild side-effect witn low cost, which deserves further exploration.

Objective To explore the risk factors in children with epilepsy and their effects on attack rate of epilepsy.Methods One hundred and sixty epilepsy patients(patient group,88 boys and 72 girls)and 150 healthy children(control group,72 boys and 78 girls)were selected.All children conformed epilepsy at the west China second hospital were consecutively included in the study for 6 months period.The range of age was from 1 month to 16 years[(7.0?4.7)years old] of patient group children.All children with epilepsy had no-causation seizure for more than twice time and were diagnosed by electroencephalogram.Neurologically normal children in same period,matched for age and sex,visiting the health care clinic were selected as controls.The range of age was from 2 month to 16 years [(6.3?4.5)years old] of control group children.The risk factors examined were febrile convulsions,head trauma,central nervous system infections,abnormal perinatal history,family history of epilepsy and parental consanguinity.The data of patients and controls were obtained from a questionnaire through personal interviews.Details on the patient,family history,and parental age at the time of childbirth were included.Medical records were then reviewed.According to the data type,the statistics were performed with ?2 test and the significance level was the P

Objective To investigate individualized and multi-phase management of recurrent epithelial ovarian carcinoma in order to improve survival of the patients. Methods From 1998 to 2002, 70 patients with recurrent epithelial ovarian carcinoma were enrolled in the present study. The treatments were divided into: (1) Induction of tumor remission:platinum sensitive patients were treated with paclitaxol + cisplatin (TP) or carboplatin + cyclophosphamide(CP)regimen; platinum resistant patients used Taxol + mitomycin(TM)or etoposide+ mitomycin(VM)regimen. Resection of tumors was done in an attempt to reduce the residual tumor with a diameter less than 1cm. Local radiotherapy was performed for those with residual tumor and who achieved clinical response after chemotherapy or surgery. (2) Consolidation therapy: chemotherapy with lower doses was administrated after disease remission. Interferon was used as immunotherapy during chemotherapy and radiotherapy. Survial analysis was done. Results (1) The 1, 2, 3, 4, 5-year survival rates were 67%, 51%, 45%, 38%, 32% . Median survival was 38.57 months. (3)The 1,2,3-year progression-free survival rates of the research arm were 41%, 37%, 24%. Median progression-free survival was 12.00 months. (4) Multivariate analysis revealed that platinum-free interval (P

Tensegrity structure is comprised of compression-resis tant elements and a set of continuous tensile elements that are interconnected w ith each other. The stability of such system depends on maintenance of tensional integrity inside the structure, or what has come to be termed “tensegrity”. A ccording to studies on biology, cell structures are assembled on the basis of te nsegrity mechanism. Tensegrity of cytoskeleton can affect cell shape and functio n. Furthermore, some basic rules of mechanochemical transduction in cells can be well explained using tensegrity theory.

Objective To investigate the quality of life of nurses group in Shenzhen city and explore its influencing factors, so as to provide evidence for health policy making health promotion and science research. Methods Self-designed questionnaires were used in social demography survey and SF-36 was adopted to survey 495 in-service nurses on front line from four hospitals in Shenzhen. Paired samples t Test and multivariable stepwise regression were carried out to analyze the quality of life among nurses in Shenzhen city and general population in China. Results The data showed the scores of the physiological domain, psychological domain and quality of life nurses in Shenzhen city and Chinese general population was (68.60±17.61), (69.91±17.91), (67.29±20.29)and (78.18± 15.88), (79.36±17.00), (77.00± 17.42), respectively. The difference had statistical significance. Multivariable stepwise regression showed that quality of life was positively correlated with APN scheduling, education, department, monthly income, working range, age and the hospital level in descending sort Conclusions Health authorities, hospital leaders and nurses-selves should pay more attention to the quality of life for nurses group and take positive mea-sures to improve quality of life of nurses group.

AIM: To investigate mutations of oncogene k-ras in colorectal cancer tissues and the relationship between mutations of k - ras and biological behavior of colorectal carcinoma. METHODS:The specimens of 123 patients with colorectal cancer were collected. Real - time fluorescence quantitative PCR were performed to detect k-ras mutations at codon 12 and codon 13 of exon 1, and the results were analyzed with the corresponding clinical pathological data. RESULTS: Among 123 colorectal cancer cases, point mutations were detected in 53 cases (40.8% ) , point mutations at codon 12 were found in 42 (34.1 % ) cases, and 11(8.9% ) cases at codon 13.No closely relationship between mutations of k-ras and tumor size, location, invasive depth and differentiation extent was observed. The rate of k-ras mutation in the cases with more invaded lymph nodes was higher than that in the cases without invaded lymph nodes ( P < 0.05 ) , and the rate of k-ras gene mutation in the cases with hepatic metastases was higher than that in no hepatic metastases (P <0.05). The rate of k - ras gene mutation was higher in TNM staging Ⅲ/Ⅳ than that in Ⅰ/Ⅱ( P < 0.05 ). CONCLUSION: Mutation of oncogene k-ras plays an important role in the carcinogenesis and development of colorectal cancer, and it is closely associated with invaded lymph notes and hepatic metastases, suggesting that mutation of k- ras indicates a poor prognosis.

Objective To explore the migration and differentiation of the human neural stem cells (hNSC) after being transplanted to the neonatal rat lateral ventricle,to provide some data on therapy for neonatal cerebropathy by using of neural stem cells.Methods N2 medium containing EGF+FGF2+LIF was used to culture the NSC spheres from the forebrain tissues of aborted human fetus.The hNSC was identified by detecting the NSC marker nestin antigen and showing the potency to differentiate into neural cells( including astrocytes,oligodendrocytes and neurons)by using indirect immuno-fluorescence assay(IFA).The part of the hNSC in-vitro cultured for 14 d was digested to suspensions of cell.Cultured for 14 d, the hNSC in-vitro and the suspension were transplanted into the lateral ventricles of the neonatal rat brains.The rats were respectively killed at 24,48 and 72 h respectively post-transplant,the whole brain was sectioned,and the special immuno-response detection was performed by using anti-human nuclei(anti-hNuc)and anti-human neurofilament(anti-hNF).Results In vitro culture,the typical NSC spheres were obtained from the forebrain of the human fetus.The suspensions of cells were obtained from the neurosphere.In neurosphere group, the results of anti-hNuc detecting tracing at 72 h post-injection showed that the grafts had migrated into the cortex grand layers of olfactory bulbus,medial precentral area of lobus frontalis,hippocampal,and lobus occipitalis.The label-positive cells lined along the Cerebellar Purkinje cell layers and appeared in most parts of mesencephalons.The immuno-respons results of anti-hNF showed that the positive cells scattered in the grand layer of cortex,the connection among positive cells was watched.In suspensions group,the results of anti-hNuc detecting tracing at 24 h post-injection show a great quantity of positive cells in the ventricles and injection track.At 72 h, a small quantity of positive cells remained in the ventricle and nearby brain tissue.Conclusions Whole neurospheres migrated intensely and differentiated into neurons and gliocytes.At the same time,transplants of cells from suspension transplants showed limited or no migration because of internal environment of the brain and construction of neurospheres.
