Objective: To explore the predictive factors between Meniere's disease (MD) and vestibular migraine (VM) by Gadolinium-enhanced Magnetic resonance imaging (MRI) of the inner ear and Clinical Features.
Methods: Eighty-seven patients (50 MD and 37 VM) underwent intratympanic injection of gadolinium and MRI was performed 24 h later. All patients underwent pure tone audiometry and caloric tests.
Objectives: To compare three methods of scoring endolymphatic hydrops in patients with Ménière's disease in order to assess the correlation between endolymphatic hydrops and auditory characteristics.
Methods: A retrospective study of 97 patients with unilateral definite Ménière's disease (DMD) who underwent contrast-enhanced three-dimensional fluid attenuated inversion recovery (3D FLAIR) MRI. Each patient was scored by the Inner Ear Structural Assignment Method (IESAM), the Saccule to utricle area ratio (SURI), and the Four Stage Vestibular Hydrops Grading (FSVH), according to their corresponding axial images.
To investigate the application of inner ear 3-dimensional fluid-attenuated inversion recovery (3D-FLAIR) magnetic resonance imaging (MRI) in patients with sudden sensorineural hearing loss (SSNHL) accompanied by inner ear hemorrhage. A total of 1252 SSNHL patients who were admitted from January 2010 to April 2018 were included in the study. The patients' clinical features, complete blood counts, coagulation profiles, audiometry data, and MRI scans were retrospectively reviewed.

Objective: To investigate imaging and audiology features of temporal bone and analyze the classification and prevalence of inner ear abnormalities in children with sensorineural hearing loss.
Method: Children who were diagnosed with sensorineural hearing loss were examined by high resolution CT and the inner ear fluid of MRI. And each chart was retrospectively reviewed to determine the imaging and audiology features.

Objective: To investigate the clinical features, diagnosis and prognosis of sudden sensorineural hearing loss accompanied with inner ear hemorrhage.
Methods: Eleven cases of sudden sensorineural hearing loss accompanied with inner ear hemorrhage were retrospectively analyzed, including clinical manifestation, hematological and audiological examinations, as well as characteristics of inner ear three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI).
Results: Eleven cases of sudden hearing loss with inner ear hemorrhage were accompanied by varying degrees of vertigo, lasting from several minutes to several hours, nine of whom had persistent tinnitus.
Purpose: The aim of the study is to probe whether intratympanically gadolinium contrast-enhanced three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging, together with magnetic resonance imaging scoring system of the perilymphatic space, had advantages in diagnosing patients with bilateral Meniere's disease.
Materials And Methods: Eight patients diagnosed as 'definite' bilateral Meniere's disease and two patients considered as 'possible' Meniere's disease were selected for the current study. All ten patients underwent caloric test, vestibular evoked myogenic potential and intratympanically gadolinium-enhanced magnetic resonance imaging.

Objective: To introduce the efficacy of three surgical options for juvenile nasopharyngeal angiofibroma (JNA) resection, and causes of operative bleeding.
Method: Retrospective analysis of 36 JNAs,three surgical options were used to resect the tumor. There were 15 cases of Class I tumors , using endoscopic nasal cavity approach.
We retrospectively reviewed the cases of 27 patients who experienced intraoperative bleeding during resection of a large (Fisch type III or IV) juvenile nasopharyngeal angiofibroma (JNA). Of this group, 16 patients had a type III JNA and 11 had a type IV tumor. The degree of hemorrhaging during excision of these JNAs varied greatly among individual patients.

Study Design: Retrospective medical record review.
Methods: The clinical and imaging materials of 51 cases of JNA diagnosed at our hospital between 1981 and 2011 were collected and studied.
Objectives/hypothesis: To investigate endolymphatic space images in patients with idiopathic sudden sensorineural hearing loss (ISNHL) and vertigo using three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI).
Study Design: This is a prospective study of an analysis using the imaging technology of 3D-FLAIR MRI for patients with ISNHL and vertigo.
Methods: 3D-FLAIR MRI was performed 24 hours after intratympanic injection of gadolinium-diethylenetriamine penta-acetic acid.
Objective: To explore the positive visualization rate of endolymph space in Meniere's disease (MD) by three-dimensional fluid-attenuated inversion recovery magnetic resonance imaging (3D-FLAIR MRI) and assess its diagnostic value of MD.
Methods: 3D-FLAIR MRI was performed at 24 h after an intratympanic injection of gadolinium diethylenetriamine penta-acetic acid in 51 MD patients. Then the examination results were summarized, analyzed and compared with those of vestibular evoked myogenic potential (VEMP) and glycerol tests.
20(S)-protopanaxadiol (PPD(S)) and 20(R)-protopanaxadiol (PPD(R)), the main metabolites of ginsenosides Rg3(S) and Rg3(R) in black ginseng, are potential candidates for anti-cancer therapy due to their pharmacological activities such as anti-tumor properties. In the present study, we report the preparation of PPD(S, R) by a combination of steaming and biotransformation treatments from ginseng. Aspergillus niger was isolated from soil and showed a strong ability to transform Rg3(S, R) into PPD(S, R) with 100% conversion.

Objective: To our knowledge, study of the intraoperative profuse bleeding of pterygoid venous plexus (PVP) in large nasopharyngeal angiofibroma resection has not yet been reported. Attention should be paid to this topic in clinical practice.
Method: From 1981 to 2009, 44 cases of JNAs were treated in our hospital.
A high-performance liquid chromatographic method with evaporative light scattering detection (HPLC-ELSD) has been developed to identify and quantify 19 ginsenosides (Rg(1), Re, Rf, Rb(1), Rc, Rb(2), Rd, F(4), Rg(6), Rk(3), Rh(4), 20(S)-, 20(R)-Rg(3), 20(S)-, 20(R)-Rs(3), Rk(1), Rg(5), Rs(4), and Rs(5)) in black ginseng (BG, Korean white ginseng that was subjected to nine cycles of steam treatment). Ultrasonication is employed for sample preparation, and the analysis is achieved on a Discovery C(18) column using gradient elution of CH(3)CN-H(2)O-CH(3)COOH without buffer in 40min. The method was validated by linearity (r(2)> or =0.

Materials And Methods: Six cases of JNA were extirpated surgically in the last 3 years in our department. The clinical signs, results of the total tear secretion test (Schirmer I test), imaging studies, surgical findings, and pathologic changes in these cases are reviewed retrospectively.
To optimize ginsenosides hydrolyzing beta-glucosidase production from Aspergillus niger, response surface methodology was carried out in two stages. The Plackett-Burman design was achieved to screen the important variables that influence beta-glucosidase production. Among 10 variables (wheat bran, soybean powder, CaCl(2), ginsenosides, KH(2)PO(4), MgSO(4), polyethylene glycol (PEG), medium volume, inoculum size, and stirring speed), it was found that wheat bran, KH(2)PO(4), and stirring speed had significant effect on beta-glucosidase activity due to very low p-values (p<0.

We used reverse transcriptase polymerase chain reaction (RT-PCR) and real-time reverse transcriptase polymerase chain reaction (real time RT-PCR), in situ hybridization, immunohistochemistry and Western blot techniques to localize IGF-I messenger ribonucleic acid (mRNA) and IGF-I peptide in the four parts of the antler. The specific sequence encoding IGF-I was detected by RT-PCR in all of the four specimens, and the 395 bp IGF-I sequence from the red deer antler was shown to have very high homology with human, goat and mouse IGF-I.
