[Screening, enzyme activity and genomic analysis of CH2].

Mangrove soil is a reliable source for screening cellulose-degrading bacteria due to the high diversity of microbes. To effectively utilize crop straw resources, a cellulolytic bacterium, strain CH2 was isolated from mangrove soil. We determined the carboxymethyl cellulose (CMC) and filter paper assay (FPA) activities of CH2 at different incubation times, NaCl concentrations, pH and temperatures, estimated the degradation efficiencies of rice and maize straw by CH2, sequenced and analyzed the whole genome of CH2.

Patient with Epilepsy Caused by the Spontaneous Rupture of an Intracerebral Dermoid Cyst.

Background: This is a rare case of a patient presenting with epileptic seizures and headaches who was diagnosed with spontaneous intracerebral dermoid cyst rupture via radiographic imagery, and rupture was confirmed via a pathology report.

Case Description: We report the case of a woman aged 26 years who presented with a history of chronic headache for 9 years without other symptoms, and progressive worsening of her headache had occurred for 1 month prior to admission. Radiologic examination showed a large mass located in the left temporal fossa and a large amount of homogeneous matter in the subarachnoid space of the ipsilateral cerebral hemisphere, then the tumor was completely excised.

Olfactory Impairment and Hippocampal Volume in a Chinese MCI Clinical Sample.

Purpose: The aim of this study was to evaluate the relationship between olfactory function and hippocampal volume in patients with mild cognitive impairment (MCI).

Methods: We enrolled a total of 31 MCI patients and 9 normal control subjects. All participants underwent 3.

[Effects of acupuncture on kidney morphological structure and expression of TGF-beta1 mRNA in rats with spontaneous hypertension].

Objective: To explore mechanism of acupuncture for renal interstitial fibrosis (RIF) in hypertension rats.

Methods: Twenty-four 24-week-old male spontaneously hypertensive rats were randomly divided into a model group, a perindopril group and an acupuncture group, eight cases in each one. In the acupuncture group, with rats tied up, electroacupuncture was applied at bilateral "Quchi" (LI 11) and "Zusanli" (ST 36) under mild vibration of needle handle for 20 min, once a day.

[Intraoperative magnetic resonance imaging-guided functional neuronavigation plus intraoperative neurophysiological monitoring for microsurgical resection of lesions involving hand motor area].

Objective: To explore the methods and applications of intraoperative magnetic resonance imaging (iMRI)-guided functional neuronavigation plus intraoperative neurophysiological monitoring (IONM) for microsurgical resection of lesions involving hand motor area.

Methods: A total of 16 patients with brain lesions adjacent to hand motor area were recruited from January 2011 to April 2012. All of them underwent neuronavigator-assisted microsurgery.

[Application of high-field intraoperative magnetic resonance imaging in stereotactic aspiration and drainage of hypertensive hematomas].

Objective: To explore the application values of high-field intraoperative magnetic resonance imaging (MRI) in stereotactic aspiration and drainage of hypertensive hematomas.

Methods: During a period of August 2011 to January 2012, 11 patients with hypertensive hemorrhage were examined preoperatively by conventional MRI and diffusion tensor imaging (DTI) with 1.5T intraoperative MRI system (Signa HDi, GE, USA) at Tianjin Medical University General Hospital.

[Positron emission tomography plus VEEG in the localization of epileptic foci in negative-MRI interact epilepsy].

Objective: To explore the application value of positron emission tomography (PET) in the localization of magnetic resonance imaging (MRI)-negative epileptogenic focus.

Methods: Brain images of 18fluoro-2-deoxy-D-glucose (18F-FDG) and 13N-NH3·H2O-PET, MRI and video electroencephalography (VEEG) were obtained in 65 patients. Preoperative and postoperative localizations were compared in MRI-negative patients.

[Applications of blood oxygenation level dependent-functional magnetic resonance imaging, diffusion tensor imaging and intraoperative neurophysiology monitoring in secondary epileptic surgery in M1 area].

Objective: To explore the applications of blood oxygenation level dependent-functional magnetic resonance imaging (BOLD-fMRI), diffusion tensor imaging (DTI) and cortical somatosensory evoked potentials (Co-SEP), motor evoked potentials (MEP) and electrocorticogram (ECoG) in secondary epileptic surgery of primary motor area (M1).

Methods: In 19 patients, preoperative BOLD-fMRI were performed to display the relationship between active zone, fiber bundle and epileptogenic lesions. Besides, Co-SEP, MEP and ECoG were also carried out intra-operatively to direct the resection of epileptogenic lesion and epileptogenic focus.

[Localization of epileptic foci in frontal lobe epilepsy and its surgical therapy].

Objective: To analyze the clinical data and pre-operative examination results of frontal lobe epilepsy and combine with intra-operative intracranial electrical record in order to localize epileptic foci and to direct surgical therapy.

Methods: Preoperative EEG record and MRI scan were performed in 23 patients with refractory frontal lobe epilepsy. Among them, 17 patients received interictal 18F-FDG-PET-CT, 11 received MEG examination, 2 received functional MRI, 10 received surgical operation and intra-operative intracranial electrical record.
