Multitracer PET/CT Findings in a Case of Behavioral Variant Frontotemporal Dementia With Parkinsonism.

We report the clinical and multimodal PET/CT manifestations in a patient with behavioral variant frontotemporal dementia and parkinsonism. The 18F-FDG PET scan revealed hypometabolism in the left supratentorial cortex. The 18F-fluorodopa PET scan demonstrated decreased uptake in the bilateral striatum, most prominent in the head of caudate nucleus.

Tumor-initiating cells contribute to radiation resistance in primary human renal clear cell carcinomas by activating the DNA damage checkpoint response.

The use of radiotherapy in patients with clear cell renal carcinoma (ccRCC) is predominantly limited to palliation of metastases or control of local growth, because ccRCC cells readily develop radioresistance. The mechanisms underlying ccRCC resistance remain elusive. The present study demonstrated that ccRCC cells that survive fractionated radiation treatment display tumor-initiating cell (TIC) characteristics, such as high self-renewal and tumorigenic capacities, and overexpress stemness genes.

Preliminary study of brain glucose metabolism changes in patients with lung cancer of different histological types.

Background: Cerebral glucose metabolism changes are always observed in patients suffering from malignant tumors. This preliminary study aimed to investigate the brain glucose metabolism changes in patients with lung cancer of different histological types.

Methods: One hundred and twenty patients with primary untreated lung cancer, who visited People's Hospital of Zhengzhou University from February 2012 to July 2013, were divided into three groups based on histological types confirmed by biopsy or surgical pathology, which included adenocarcinoma (52 cases), squamous cell carcinoma (43 cases), and small-cell carcinoma (25 cases).

Endoplasmic reticulum stress protects human thyroid carcinoma cell lines against ionizing radiation-induced apoptosis.

Radiotherapy is one of the most effective forms of cancer treatment, used in the treatment of a number of malignant tumors. However, the resistance of tumor cells to ionizing radiation remains a major therapeutic problem and the critical mechanisms determining radiation resistance are poorly defined. In the present study, a cellular endoplasmic reticulum (ER) stress microenvironment was established through the pretreatment of cultured thyroid cancer cells with tunicamycin (TM) and thapsigargin (TG), in order to mimic the ER stress response in a tumor microenvironment.

Male circumcision performed with 8-figure non-absorbable suture technique.

Introduction: We analyze the outcome of circumcisions performed with 8-figure non-absorbable suture (8FNS) and assess the feasibility of using the technique in male circumcision.

Methods: We randomly divided 317 patients who would undergo circumcision between February 2009 and January 2012 into 2 groups. Each group was subdivided into children (age range: 7 to 15 years) and adult (range: 16 to 85 years).

Initial study of magnetic resonance diffusion tensor imaging in brain white matter of early AIDS patients.

Background: HIV is a neurotropic virus which can cause brain white matter demyelination, gliosis, and other pathological changes that appear as HIV encephalitis or AIDS dementia. The purpose of this study was to investigate the change of the diffused condition of water molecules in brain white matter in early acquired immune deficiency syndrome (AIDS) patients using MR diffusion tensor imaging (DTI).

Methods: DTI examinations were performed on a Siemens 3.

[A report of 4 cases about gluteal heterotopic ossification caused by injection].

Objective: To study the pathogenesis and treatment of gluteal heterotopic ossification caused by injection.

Methods: From April 2006 to May 2011, 4 old female patients with gluteal heterotopic ossification caused by injection were treated by resection. The average age was 71 years old ranging from 67 to 76.

Distinction between postoperative recurrent glioma and delayed radiation injury using MR perfusion weighted imaging.

Introduction: Distinction between postoperative recurrent glioma and radiation injury remains a tough diagnostic problem for routine imaging methods. The purpose of this study is to evaluate the differentiated effectiveness of perfusion weighted imaging (PWI) for the two entities.

Methods: PWI was performed using Siemens 3.

Minimally invasive plate internal fixation for calcaneal fractures.

Objective: To assess the clinical efficacy of minimally invasive plate internal fixation for the treatment of calcaneal fractures.

Methods: Manual reduction, rectification of deformity, and cold compress with traditional Chinese medicine were used preoperatively to relieve swelling and pain. A small incision was made to expose the articular facet and to perform anatomic reduction and plate fixation.

Non-enhanced MR angiography of renal artery using inflow-sensitive inversion recovery pulse sequence: a prospective comparison with enhanced CT angiography.

Purpose: To prospectively evaluate the diagnostic value of non-enhanced inflow-sensitive inversion recovery (IFIR) MR angiography for the detection of renal artery stenosis (RAS), with enhanced CT angiography performed as the reference standard.

Materials And Methods: Sixty consecutive patients suspected of RAS underwent both of IFIR MR and enhanced CT angiography. Subjective image quality, renal artery depiction and renal artery grading were all evaluated on artery-by-artery basis.

Distinction between postoperative recurrent glioma and radiation injury using MR diffusion tensor imaging.

Introduction: This study aims to evaluate the differentiated effectiveness of MR diffusion tensor imaging (DTI) to postoperative recurrent glioma and radiation injury.

Methods: Conventional MRI and DTI examination were performed using Siemens 3.0 T MR System for patients with new contrast-enhancing lesions at the site of treated tumor with postoperative radiotherapy.
