Objective To study the value of video EEG combined with MRI in the diagnosis of intractable epilepsy.Methods40 patients with intractable epilepsy treated in our hospital from 2013 to 2015 were selected as the subjects.In 40 patients, 26 patients with hippocampal sclerosis, 2 cases of patients with temporal lobe atrophy with cerebral dysplasia, 4 cases of patients with cerebral gray matter and macrogyria, 3 cases of vascular malformation, 1 cases of patients with intracerebral cyst, 2 cases of patients with glioma, 2 cases of patients with traumatic epilepsy.Retrospective of The clinical data of the selected patients were analyzed and the manifestations of epileptic foci were reflected by MRI, The use of video EEG was used to detect the status and source of EEG during epileptic seizure and epilepsy Analysis, combined with MRI scan and video EEG results, control surgery pathological changes, analysis of the results, draw conclusions.ResultsThere were 21 cases of the accurate location of interictal EEG.The accuracy was 52.5%, and the accuracy of the location of epileptogenic foci was about 40, and the accuracy was about 100%.The accuracy of MRI in the diagnosis of epileptic foci and related lesions was 35 cases, the accuracy rate was 87.5%, and the number of lesions was qualitative and accurate in the case of 30 cases, with an accuracy rate of 75%.ConclusionVideo EEG combined with MRI examination for drug refractory epilepsy diagnosis has important clinical value, can make a more accurate diagnosis of patients with epileptogenic foci, provide information for surgical treatment of intractable epilepsy patients, with further clinical promotion and application significance.

Objective To explore the effects of oligohydramnios in the late trimester of pregnancy on perinatal infants.Methods Two hundred and sixty-eight pregnant women with oligohydramnios,admitted from June 2000 to June 2007,were involved in present study,and homochronous 300 pregnant women with normal volume of amniotic fluid were enrolled as control group.The clinical data were analyzed to evaluate the influence of oligohydramnios on perinatal infants and on the outcome of delivery.Results The incidences of newborn distress,meconium-contaminated amniotic fluid,apnoea neonatorum,aspiration pneumonia and perinatal infant mortality were obviously higher in the oligohydramnios group than those in control group(P

Garcinia plants are one of the rich sources of natural xanthones and benzophenones which have attracted a great deal of attention from the scientists in the fields of chemistry and pharmacology. Recently, many structurally unique constituents with various bioactivities, especially anti-tumor activity, have been isolated from Garcinia plants. This concise review focused on the anti-cancer activity natural products isolated from Chinese Garcinia plants, and the research finding by authors and collaborators over the past several years were cited.

Objective: To evaluate the impairment of semantic memory in Alzheimer's disease.Methods: 22 Alzheimer's disease patients were examined by means of a longitudinal study and compared with 22 normal elders.Two semantic tasks,lexical decision task and semantic knowledge task were used,to evaluate the integrity of the same concepts.Results: In each session,the MMSE scores of the Alzheimer's disease group were significantly worse(P

Objective To explore the absorption characteristics and mechanism of P-glycoprotein (P-gp) mediated transport of oleanolicacid (OA)across membrane in vitro.Methods The intake and transport of OA were evaluated by an HPLC/MS quantitative detection method.Safe concentration range of OA was determined by MTT.The effect of different drug concentration,incubation time,pH and temperature on the intake of OA by Caco-2 cells were investigated.The effect of P-gp inhibitor on the transmembrane transport of OA was investigated by the Caco-2 cell monolayer model,and the apparent permeability coefficient (Papp) was calculated.Results The uptake of O A was concentration-time dependent and correlated negatively to temperaturein Caco-2 cells within the safe concentration range,but was not significantly affected by pH value.Compared with controls,the Papp significantly changed when the P-gp inhibitor was added to the model(P ＜ 0.05).The apparent permeability ratio decreased from 2.90 to 0.95.Conclusion The absorption of OA was primarily by passive diffusion and might be mediated by the effiux by P-gp.

Objective To assess the effect of repetitive transcranial magnetic stimulation (rTMS) at different frequencies on behavioral and psychological symptoms and cognitive function in patients with Alzheimer's disease.Methods Seventy-two patients were randomly divided into a high frequency group,a low frequency group and a control group (n =24 for each),and given 10 Hz,1 Hz or sham rTMS over the left and right dorsolateral prefrontal cortex at an intensity was 80％ of each patient's movement threshold.The stimulation was for 30 min a day,five days a week.During the 4 weeks of treatment,risperidone was used at a fixed dose of 1 mg per day for all patients.Before and after the treatment,all 3 groups were assessed using the behavioral pathology in Alzheimer's disease rating scale (BEHAVE-AD) and the mini-mental state examination (MMSE).Results Two weeks after the treatment,the average BEHAVE-AD score of the high frequency group had decreased significantly from (16.75±6.26) to (13.84± 6.10),significantly lower than the low frequency and the control groups' averages.Two weeks later,the average BEHAVE-AD scores of the 3 groups were significantly lower than before the treatment,but the decrease of the high frequency group was of significantly greater compared to the other 2 groups.Four weeks after the treatment the average MMSE score of the high frequency group was significantly better than before the treatment (P＜0.01),and better than the low frequency and the control group's averages.The effectiveness rates of the high frequency group,the low frequency group and the control group were 88％,58％ and 54％ respectively,all significantly different.Conclusion High frequency (10 Hz) rTMS combined with risperidone can improve the behavioral and psychological symptoms and cognitive function of AD patients,while low frequency (1Hz) rTMS does not have obvious effects.

OBJECTIVETo explore the method of the treatment for hallux valgus with the proximal crescentic osteotomy of the first metatarsal bone, combining with distal lateral soft tissue release.

METHODSFrom January 2008 to December 2012, 21 cases 21 hallux valgus feet were treated by operative procedure, included 1 male (1 foot) and 20 females (20 feet), with the mean age of 52 years (range, 36-68 years). Among all patients were followed up for 12 to 26 months, with the mean 16 months. The preoperative, post-operative and final follow-up X-ray films of all patients were collected. The hallux valgus angle, intermetatarsal angle and distal metatarsal articular angle were measured and analyzed. The surgical outcome was evaluated combined with the AOFAS score.

RESULTSThe average hallux valgus angle decreased from 42.3° ± 1.8° preoperatively to 14.5° ± 1.8 postoperatively, the average intermetatarsal angle did from 21.9° ± 1.7 to 9.1° ± 1.8°, and the average distal metatarsal articular angle did from 14.9° ± 1.8 to 7.2° ± 1.5, respectively. There were significant differences between the preoperative and postoperative roentgenographic index. AOFAS score was improved from 44.0 ± 1.8 preoperatively to 83.9 ± 2.2 at the final follow-up.

CONCLUSIONSThe proximal crescentic osteotomy of the first metatarsal bone combined distal soft tissue reconstruction obtained satisfactory results in severe hallux valgus patients with big intermetatarsal angle.
