Epilepsy is a complications of brain injury or stroke,and is a common diseases in reha-bilitation or neurology department.Transcranial magnetic stimulation as a classical treatment means for stroke or brain injury,but also can promote the recovery of epilepsy.However,there is no clear clinical re-port for safety of epilepsy patients use both donepezil and transcranial magnetic stimulation .The article re-views the literature.Clinicians maybe provided some help.

Two high protease producing strains, whic h are desi gnated Aspergillus oryzae AS100 and AS102, were screened and applied as main fermentation strains of swine blood meal. A Saccharomyces cerevisiae Y113 and a Bacillus Asp007 were also used as assistant fermentation strains. The enzyme production abilities we re studied,and a series of parameters of the fermentation technology were deter mined. Through swine blood meal fermentation, a high-protein fermented feed wa s produced, which is strong soy flavor and was rich in protein(69%), free amino acid, vitamin such as VitD 3 and niacin and organic elements such as Fe. It is a kind of high-protein feed for animals and it could be used as feedstuff addi tive.

Objective • To observe the effect of protease activated receptor 2 (PAR2) on the colonic motility in diabetic mice and investigate the mechanism. Methods • The mouse model of type 1 diabetes mellitus was established by intraperitoneal injection of streptozotocin. The smooth muscle strips and segments of colons were isolated. The effects of PAR2 agonist on colonic motility were observed by muscle strip tension contraction and colonic migrating motor complex experiments. The effect of small conductance calcium-activated potassium channel (SK3 channel) antagonist on it was also observed. Results • PAR2 agonist inhibited colonic motility and colonic smooth muscle was more sensitive to PAR2 agonist in diabetic mice. PAR2 agonist-induced inhibition was inhibited by SK3 channel antagonist. Conclusion • PAR2 activity in diabetic mice colons is significantly enhanced, which may inhibit colonic motility through SK3 channel.

Modified electroconvulsive therapy (MECT) is a fast and effective physical therapy method currently widely used in psychiatry. The anesthesia target of this treatment is to calm the patients, relax the muscles and maintain stability in histodynamics during treatment, meanwhile avoiding affecting efficacy, because too deep anesthesia can inhibit discharge of the cerebral cortex. However, current anesthetic drugs in MECT, including muscle relaxants, intravenous anaesthetics, inhalation anaesthetics, analgesics, etc., lack the best compatibility of anesthesia induction. This review discusses the application and compatibility of these drugs in MECT in recent years, in order to provide reference for the best anesthesia induction protocol for MECT.

ObjectiveTo observe the effect of rehabilitation on post stroke depression with different treatment methods.Methods68 post stroke depression patients were randomly divided into treatment group, who accepted Bobath approach combined with Chinese herbs and acupuncture, and control group, who accepted Bobath approach only. Evaluation was conducted before treatment and 3 and 6 weeks after treatment with Hamilton Assess Depression Scale (HAMD), and activity of daily living (ADL).ResultsThere was no significant difference before the treatment between these two groups. 3 weeks after treatment, the score improved, but no significant enough in the both groups. 6 weeks after treatment, the scores of MBI and HAMD in treatment group significantly improved compared with that before treatment(P<0.05). ConclusionBobath approach combined with Chinese medicine is effective on improving depressive symptoms and ADL in post stroke depression patients.

Objective To evaluate the utility of short tau inversion recovery (STIR) sequence in the diagnosis of hippocampal sclerosis ( HS).Methods Twenty-one patients with medial temporal lobe epilepsy without neoplasm lesions or injuries by conventional MRI sequence including T1WI,T2WI and FLAIR were included in this study.STIR imaging in axial,coronal and sagittal sequences was performed on these patients. Diagnosis of HS was based on the findings of hippocampal atrophy,alteration signal,disturbed internal structure and enlargement of the inferior horn. The findings shown on conventional MRI were compared with those on STIR sequence. Furthermore,the correlation of radiologic and histological findings was investigated in 6 patients operated for refractory seizures. Results On conventional MRI sequence,14 patients (66.7％) were confirmed with unilateral HS and 4 patients were suspected with unilateral HS. In contrast,all these 18 patients (85.7％) were confirmed with unilateral HS by STIR.Particularly,STIR sequence delineated the internal structure of hippocampus more clearly than conventional MRI sequences did. C shaped contour in subiculum-CA1-CA2 was revealed in normal hippocampus on STIR sequence and disappeared in HS,correlated to the pathology finding of loss of neuron in CA1 in resected tissues in 6 operated patients.The patients with HS also showed areas of hypodensity in CA4 on STIR,in accordance with pathologic findings of gliosis in this area in the 6 operated patients.Conclusion STIR sequence could depict the internal anatomical structure of hippocampus with high resolution superior to conventional MRI sequences,and can be of great value in the diagnosis of HS.

Objective To evaluate family economic burden of children with autism, or with physical disability or with intellectual disability.Methods227 parents of children with autism, children with physical disability, children with intellectual disability and normal children were interviewed for their family economic burden.ResultsThe medical cost and caring cost of children with disability were significantly more than those of normal children, and the education cost, clothes cost and amusement cost of children with disability were significantly less than those of normal children. Family income was only affected by education level of parents. Families of children with disability received more economic assistance than families of normal children except families of autistic children. More children the family had, less economic assistance the family acquired. Compared with normal children, the family economic burden of children with disability were as following, children with autism (19582.4 RMB per year), children with physical disability (16410.1 RMB per year), children with intellectual disability (6391.0 RMB per year). ConclusionFamilies of children with autism, children with physical disability and children with intellectual disability had heavier economic burden than families of normal children.

Objective To explore the antitumor effects of metformin on ovarian cancer cells in vitro, particularly on tumor cell proliferation, cell cycle, apoptosis, migration, and possible mechanism. Methods Ovarian cancer cell lines (A2780, CAOV3, and SKOV3) were treated with different concentrations of metformin. Their proliferation was explored using the MTT and clone formation assays, cell migration was examined using the scratch and Transwell assays, and cell cycle and apoptosis were examined using flow cytometry. In addition, metformin’s effects on the phosphorylation of AMPK and mTOR and the expression of CXCR4 and Wnt/β-catenin protein was measured by Western blot. Results The survival rates of ovarian cancer cells decreased significantly with increasing metformin concentration and metformin treatment time. The IC₅₀ values of metformin at 48 h for A2780, CAOV3, and SKOV3 cells were 16.36, 36.65, and 43.44 mmol/L, respectively. Compared with the control group, the clone formation ability and cell migration ability of ovarian cancer cells were significantly inhibited by metformin treatment and cell cycle arrested at the G₀/G₁ phase, and the apoptosis rate increased. As metformin concentration increased, the expression of phosphorylated AMPK protein gradually increased, and the expression levels of phosphorylated mTOR, CXCR4, Dvl3, β-catenin, cyclin D1, and CDK1 decreased. Conclusion Metformin exerts an antitumor effect on ovarian cancer cells, which is related to the activation of AMPK to inhibit CXCR4-mediated Wnt/β-catenin signaling pathway.
