Melodic intonation therapy (MIT) positively impacts the speech function of patients suffering from aphasia and strokes. Fixed-pitch melodies and phrases formulated in MIT provide the key to the target language to open the language pathway. This randomized controlled trial compared the effects of music therapy-based MIT and speech therapy on patients with non-fluent aphasia.

We provide a case of a patient with typical corpus callosum syndrome following a traumatic brain injury, and demonstrate neural reorganization and significant neural regeneration after comprehensive rehabilitation, using diffusion tensor imaging fiber bundle tracking.
Patient Concerns: We found typical clinical manifestations of damage to the corpus callosum.
Objective: The purpose of this study was to compare the efficacy of repetitive transcranial magnetic stimulation (rTMS) applied at different frequencies to the contra-lesional hemisphere to optimize the treatment of post-stroke non-fluent aphasia.
Method: Patients with post-stroke non-fluent aphasia were divided randomly into four groups: a high-frequency rTMS (HF-rTMS) group (10 Hz), a low-frequency rTMS (LF-rTMS) group (1 Hz), a sham stimulation group, and a control group. All groups received the standard treatment (consisting of drug therapy, conventional physical exercises, and speech training); in the HF-rTMS and LF-rTMS, this was supplemented with magnetic stimulation that targeted the mirror area within the right hemispheric Broca's area.
Morchella (morel) includes prized edible and medical mushrooms in the world. Since 2012, commercial cultivation of morels in the field has developed rapidly in China. However, coupled with the rapid expansion of morel cultivation, diseases have been become serious threats to morel production.

Methods: Clinical courses were retrospectively reviewed for 38 consecutive patients who underwent microsurgical resection of symptomatic BSCMs in the sub-acute phase between January 2000 and December 2009. Microsurgery was performed with the help of intraoperative neuronavigation and neurophysiological monitoring.
Background: Malignant cerebral infarction often occurs in patients with massive cerebral infarction. Monitoring brain edema is therefore helpful to make correct clinical decisions. Our previous studies have confirmed that cerebral electrical impedance (CEI) can sensitively reflect the brain edema after stroke.

Methods: Data from 67 patients with TSMs who underwent microsurgical treatment by a frontolateral approach (n=44) or fronto-orbital approach (n=23) between January 2002 and December 2008 were retrospectively collected and analyzed. Change in visual function was evaluated as the main outcome.
Objective: To investigate the change of brain edema in patients with cerebral infarction by non-invasive cerebral electrical impedance (CEI) measurements.
Methods: An invariable secure current at a frequency of 50 kHz and an intensity of 0.1 mA was given into a person's brain.
Objective: To explore the primary regularity of cerebral electrical impedance (CEI) change in healthy people, patients with intracerebral hemorrhage (ICH) and patients with cerebral infarction (CI).
Methods: CEI of 200 healthy volunteers, 78 patients with ICH and 51 patients with CI were measured by noninvasive brain-edema monitor. The results of perturbative index (PI) converted from CEI were compared with the volumes of infarction, hematoma and surrounding edema, which were calculated by image analysing system according to MRI or CT scan.

Objective: To duplicate a model of hypoxic-ischemic brain damage (HIBD) in the neonatal rat to create unilateral cerebral damage.
Methods: Healthy 7-day-old Sprague-Dawley (SD) rats were used as research subjects and randomly divided into 3 groups: the control group (n = 18), the sham operated group (n = 8), and the HIBD group (n = 19). The HIBD model was produced according to the traditional Rice model and the brains were collected when the rats were 14 days old.
Objective: To explore the mechanism and type of acute infectious brain edema induced by injection of pertussis bacilli (PB) in rat neocortex, to study the neuroprotective effect of non-competitive antagonist of N-methl-D-aspartate (NMDA) receptor (MK-801) and antagonist of Ca(2+) channels (nimodipine) on brain edema, and to investigate the relationship between percentage of water content and cytosolic free calcium concentration ([Ca(2+) ](i)) in synaptosomes or content of Evans Blue (EB).
Methods: 95 SD rats were randomly divided into five groups, ie, normal control group, sham-operated control group, PB group, nimodipine treatment group and MK-801 pretreatment group. The acute infectious brain edema was induced by injection of PB into the rats.
