A comparative study of SPECT,BEAM, EEG and CT in the localization of epileptogenic focus is reported in 40 cases of intractable epilepsy. The majority of cases showed decreased rCBF and slow waves in the epileptogenic foci during inter-ictal periods. Localization rates of epileptogenic fool by SPECT and BEAM were higher than by EEG or CT. The results showed that vasidilating agents may be useful in the treatment of intractable epilepsy.

Objective To explore influence of electroacupuncture on somatostatin expression of newborn neurons in the hippocampus of chronic epilepsy rats.Methods The double-label immunofluorescence with confocal microscope was used to observe somatostatin expression of newborn neurons in the hippocampus of chronic epilepsy rats after electroacupuncture stimulation of Dazhui (GV14)' and Baihui (GV20)' in DuMai.Results Somatostatin expression of newborn neurons was found in the hippocampus.Moreover,in somatostatin expression of newborn neurons,epileptic rats with electroacupuncture had less than epileptic rats in the hippocampus.The former had an obviously significant difference compared with the latter (P

Objective To observe and evaluate the clinical efficiency and safety of topiramate for treatment of patients with various types of epilepsy Methods 142 patients suffering from epilepsy were underwent the treatment of topiramate, of them 93 cases received a to piramate add on therapy and 49 cases a monotherapy The efficiency and side effects were evaluated after 8 weeks titration period and 12 weeks stabilization period Results The total effective rate was 79% and 84% in add on group and monotherapy group respectively The seizure free rate was 28% and 41% in two groups respectively The optimal dosages were 100～200 mg/d in adults and 3～5 mg/d in children Side effects were generally mild Conclusion Topiramate is a highly effective, safe and widespread first line antiepileptic drug which can be used as a monotherapy or add on treatment

Objective: To investigate validities of MMPI- 2 measures of general maladjustment in people who had expe- rienced traumatic events. Methods: Participants were 43 patients with stress disorder (SD) and 44 well- adjusted trauma survivors(TS). Validities of 7 MMPI- 2 measures of general maladjustment were compared with the mean scores on 8 clini- cal scales (M8), which were considered as the criterion measure of general maladjustment. Results: Patients with SD ob- tained significantly higher scores on 6 measures and M8 than TS. Most of the measures were significantly related to M8 in both groups. Although F and PK sometimes added significantly to the variance accounting for the criterion measure, Pt added significantly and meaningfully to each of the other MMPI- 2 measure in predicting maladjustment. Conclusion: The results support the use of the MMPI- 2 as a measure of general maladjustment in trauma survivors. Pt emerges consistently as a good indicator of general maladjustment.

Objective To analyze the epidemiological characteristics of the severe cases of hand , foot and mouth disease ( HFMD) in Danzhou and to provide a scientific evidence for the prevention of severe HFMD.Methods Descriptive epidemiological analysis was used to analyze the characteristics of severe ca -ses of HFMD occurred from 2010 to 2014 .Results A total of 18 960 cases of HFMD were reported in Danzhou City from 2010 to 2014.The death rate (annual deaths/1000 persons) was 0.13%.One hundred and eighty-eight cases (0.99%) were diagnosed as severe HFMD with a male to female ratio of 2.4 :1 and 96.28%of them were scattered inhabiting children .Six cases were died from severe HFMD and all of them were under 2 years of age.In total 87.77%of the severe cases were occurred in children under 2 years of age.The severe cases were mainly occurred in June and July .Children form the countryside showed higher rates of severe HFMD than those from cities and towns .No significant differences in the time between the in-itial diagnosis and treatment for children with HFMD in countryside and urban areas were found .However , the differences in the duration from initial diagnosis to severe HFMD between children in countryside and ur -ban areas were statistically significant (M-W test, P<0.05).Among the 188 severe cases, 82.44% were initially diagnosed as common HFMD cases by the county-level medical institutions and 90.96%were diag-nosed as severe cases by the municipal and above medical institutions .The cases positive for EV71 strains accounted for 44.15%.Conclusion Most of the severe HFMD were developed in scattered inhabiting chil-dren under 2 years of age in the countryside of Danzhou during 2010 to 2014.In order to decrease the mor-bidity and mortality of severe HFMD in children , it is necessary to implement health education for residents , to improve the professional skills of medical staffs in the early diagnosis of HFMD , and to strengthen etiologi-cal surveillances and warning system for HFMD .

Objective To investigate the related brain areas and nucleus involved in the inhibition of vagus nerve stimulation (VNS) on epilepsy. Methods Using the kainic acid kindling epilepsy rats model,we observed the distribution of Fos positive neurons in the brain after VNS treatment combined with immunohistochemical method. Results VNS induced a significant increase in Fos immunoreactivity in the bilateral nucleus of solitary tract,the locus coeruleus,parabrachial nucleus,periaqueductal gray of midbrain,lateral habenular nucleus,paraventricular thalamic nucleus,rhomoid thalamic nucleus,paraventricular hypothalamic nucleus.Dense Fos immunoreactive staining was also seen in the central nucleus of amygdala,bed nucleus of stria terminalis,lateral septal nucleus and prepirifiorm cortex.Pretreatment with electric stimulation on cervical vagual nerve stem, c fos expressing of hippocampus formation,cingulate gyrus and frontal,parietal,temporal lobus significantly diminished after KA injection. Conclusion This finding may suggest that VNS activates various brain structure that could be involved in the regulation of seizures.

AIM To examine the effect of metabotropic glutamate receptor ligand (s) 4 carboxy 3 hydroxyphenyl glycine 〔(s) 4C3HPG〕 on kainic acid induced epileptic seizures and brain damage in rats. METHODS Rats were given (s) 4C3HPG (500 nmol/rat) by icv infusion prior to kainic acid (KA) injection ip(10 mg?kg -1 ). The behavoir changes, electrographic seizure duration and histological alterations between different group of rats were compared. RESULTS (s) 4C3HPG markedly reduced seizures severity in response to kainate. The seizure score in the rat with (s) 4C3HPG injection icv was significantly lower than that of control during the first three hours observation period after KA administration ( P

AIM: To investigate the effects of nitric oxide(NO) and caspase-3 on dopamine-induced apoptosis in PC12 cells. METHODS: Flow cytometric assay was used to quantify the apoptotic cells. The morphological of apoptotic cells was evaluated by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL). Nitrite was quantified by Griess reaction. Inducible nitric oxide synthase(iNOS) mRNA was identified by semiquantitative reverse transcription polymerase chain reaction(RT-PCR). Caspase-3 activity was determined by fluorescent spectrofluorometer. RESULTS: Dopamine induced PC12 cells apoptosis in a concentration-dependent manner (0.15-0.60 mmol/L), with positive TUNEL staining. During the development of apoptosis, the expression of iNOS mRNA and the levels of NO increased markedly, so did caspase-3 activity(P

Objective To investigate the dosimetric performance of two algorithms for correcting the presence of tissue inhomogeneities,the finite site pencil beam (FSPB) and X-ray voxel Monte Carlo (XVMC) plans were implemented in the MONACO system,with the accuracy of application to clinic treatment of two algorithms were evaluated.Methods In a non-uniform artificial anthropomorphic phantom,regular open fields and intensity modulation radiated therapy (IMRT) plans of the MONACO were measured by using calibrated EBT2 films,and the dose accuracy of the two kinds of plans was analyzed by comparing the planned and measured plane dose.Results In an anthropomorphic phantom,the deviations between the calculated values by XVMC and the measured values by films were less than ± 2％.While the deviations of FSPB values between calculation and measurements was within ± 3％,except at the condition of 15 MV,10 cm ×2 cm field,the dose error in lung was up to 6.51％.The verification of individual IMRT beams based on films showed that the pass rates of calculation by XVMC and FSPB were larger than 90％ with γ criterion of 3％/3 mm and 4％/4 mm,respectively.At 3％/3 mm,the pass rates of FSPB were in the range of 80％-90％.At the same time,the pass rates of all individual fields were higher than 90％.Conclusions The accuracy of dose calculation of XVMC is better than that of FSPB when being in multi-segments and non-uniform media.The error of algorithm can be controlled within ±3％,for the calculation by XVMC.And the dose deficiency of PTV arising from algorithm can be avoided.

Objective: To quantify the effect of motor-developmental Tuina therapy on 61children with cerebral palsy. Methods: All the children received the motor-developmental Tuina therapy for 20 min each time, 3 to 6 times per week. The gross motor functions of the children were evaluated by GMFM 66. The baseline period evaluations in 15 children and follow-up period evaluations in 26 children were performed. Results: GMFM 66 score significantly increased at the end of treatment period (P<0.001). The GMFM 66 score changes per month in treatment period was significantly greater than those of both baseline period and follow-up period (P<0.001). Conclusion: The effect of motor-developmental Tuina therapy was notable on children with cerebral palsy. Continuous progress of the gross motor functions in these children may be obtained by continuous therapy.
