MR imaging of epithelial ovarian cancer: a combined model to predict histologic subtypes.

Objective: To compare the performance of clinical features, conventional MR image features, ADC value, T2WI, DWI, DCE-MRI radiomics, and a combined multiple features model in predicting the type of epithelial ovarian cancer (EOC).

Methods: In this retrospective analysis, 61 EOC patients were confirmed by histology. Significant features (p < 0.

Resting-State fMRI findings in patients with first-Episode idiopathic epilepsy before and after treatment.

Objective: To detect resting-state functional MRI (rsfMRI) changes and their relationships with the clinical curative effect of anti-epileptic drugs (AEDs) for complex partial seizures (CPS) in epilepsy patients using the fractional amplitude of low frequency fluctuation (fALFF).

Methods: rfMRI data from 14 CPS patients enrolled between June 2015 and June 2016 in Department of Neurology, Affiliated Hospital of Inner Mongolia Medical University were retrospectively investigated and compared with findings from 14 healthy age-, gender-, handedness-, and education-matched subjects. The patients were treated with first-line antiepileptic drugs for 12 weeks before undergoing a second rfMRI scan.

Application of high-field magnetic resonance imaging in Parkinson's disease.

The present study aimed to observe the structural changes of the extracorticospinal tract in Parkinson's disease (PD) using susceptibility-weighted imaging (SWI) and diffusion tensor imaging (DTI) magnetic resonance (MR) scans. The association of DTI parameters and brain-iron accumulation with PD was examined and imaging signs useful in the diagnosis of PD were explored. The study included 30 patients with PD and 30 age- and gender-matched healthy controls who underwent routine MR, SWI and DTI scans.

A novel method for evaluating brain function and microstructural changes in Parkinson's disease.

In this study, microstructural brain damage in Parkinson's disease patients was examined using diffusion tensor imaging and tract-based spatial statistics. The analyses revealed the presence of neuronal damage in the substantia nigra and putamen in the Parkinson's disease patients. Moreover, disease symptoms worsened with increasing damage to the substantia nigra, confirming that the substantia nigra and basal ganglia are the main structures affected in Parkinson's disease.

Alveolar soft part sarcoma: Clinicopathological analysis and imaging results.

Alveolar soft part sarcoma (ASPS) is a rare, malignant, soft-tissue tumor that accounts for ~1.2% of all soft-tissue sarcomas. Due to its low incidence, clinicians often overlook the diagnosis.

Struma ovarii accompanied by mature cystic teratoma of the other ovary: A case report and literature review.

Struma ovarii, as a monodermal variant of ovarian teratoma, constitutes <3% of ovarian teratomas. It is difficult determine a diagnosis prior to surgery. The current study reports an unusual case of struma ovarii occurring in a 49 year-old female, which was accompanied by mature cystic teratoma involving the other ovary.

Misdiagnosis of pancreatic papillary mucinous cystadenocarcinoma: A case report.

The morbidity of papillary cystadenocarcinoma of the pancreas is extremely low and the condition is rarely first found as spinal metastases, thus it is often misdiagnosed prior to surgery. The present study reports a case of papillary cystadenocarcinoma with thoracolumbar metastases in a 56-year-old male. The first symptom to occur was backache, however, computed tomography revealed no positive findings.

[Prevalence, detection, management, and control of hypertension in the population of Mongolian and Han nationalities with age ≥ 55 years in a pastoral area of Inner Mongolia Autonomous Region].

Objective: To know about the status of hypertension among Mongolian and Han aged older than 55 years living in pastoral area of the Inner Mongolia Autonomous Region.

Methods: Stratified sampling method was adopted and 9146 people aged 55 years or older were selected, blood pressure measurement and related information were collected, prevalence, awareness, treatment and control rates of hypertension were analyzed.

Results: The hypertension crude prevalence rate of Mongolian and Han subjects was 54.

[A prevalence study on mild cognitive impairment among the elderly populations of Mongolian and Han nationalities in a pastoral area of Inner Mongolia].

Objective: To understand the epidemiological characteristics and distribution of mild cognitive impairment (MCI) in elderly populations from Mongolian and Han nationalities living in the pastoral areas of Inner Mongolia Autonomous Region of China.

Methods: According to the MCI clinical diagnostic criteria from Diagnostic and Statistical Manual of Mental Disorders 4th revised edition (DSM-IV) by American Psychiatric Association, the individuals under study were at the age of 55 or over, with Mongolian or Han ethnicities and living in the pastoral area of Inner Mongolia.

Results: The crude MCI morbidity rates of Mongolian and Han of the study populations in the pastoral area of Inner Mongolia Autonomous Region of China was 19.

An ictal epilepsy case monitored by resting-state fMRI.

Most resting-state functional MRI studies of epilepsy are conducted in the interictal phase as the ictal phase is not suitable. We report and discuss a 13-year-old female epilepsy patient who had ictal examination. She was diagnosed with simple partial seizure epilepsy and on regular anti-epileptic drugs.

Hemangioblastoma originating from the right cerebellopontine angle.

The morbidity of hemangioblastoma in the supratentorial region is very low, and is seldom found in the area of the cerebellopontine angle, so it is easily misdiagnosis before surgery. We report and discuss a case of hemangioblastoma originating at the right cerebellopontine angle in a 42-year-old female patient.

Research progress on resting state fMRI of epilepsy.

As a study method of resting state network (RSN), resting state functional MRI (rfMRI) can be applied to detect low frequency fluctuate (LFF) in various cerebral areas based on resting state blood oxygen level dependence (BOLD) signals; and it is easier and more consistent than task-related fMRI. The development, features and methods of rfMRI as well as the application in epilepsy were reviewed in this article.

Effect of thyrotropin-releasing hormone on cerebral free radical reactions following acute brain injury in rabbits.

Objective: To investigate the early effect of thyrotropin-releasing hormone (TRH) on cerebral free radical reactions after acute brain injury in rabbits.

Methods: 30 healthy white rabbits were randomly divided into three groups: Group A (n=10), Group B (n=12) and Group C (n=8). The rabbits in Group A and Group B were injured by direct hit.
