It has been reported that the positive detection rate of Fluorine-18-fluorodeoxyglucose (The TGF-β1 antibody was obtained from Bioss Inc. The Huh-7 cell line (Liver Cancer Institute, Zhongshan Hospital, Fudan University) is a HCC cell line with high metastatic potential. Each mouse was subcutaneously injected with 5×10The average percentage of injected dose per gram of tissue (ID%) was 1,3% and 2,4%. The tumor was strongly positive for TGF-β1.This pilot study provides an experimental basis for further exploration of the feasibility of TGF-β1 receptor as a target in HCC imaging and in other cancers.

To evaluate the value of fluorine -18-fuoro-2-deoxyglucose positron emission tomography/computed tomography (Nineteen patients with pathologically-confirmed SMPC were collected. Clinical andA total of 38 lesions were identified, which were most frequently located in gastrointestinal tract (n=16), followed by lung (n=10), breast (n=4), kidney (n=4), liver (n=2), pancreas (n=1) and thyroid (n=1). Pathologies of these 38 lesions were 18 adenocarcinomas, 8 squamous cell carcinomas, 4 breast invasive ductal carcinomas, 4 renal cell carcinomas, 2 hepatocellular carcinomas, 1 pancreatic ductal adenocarcinoma and 1 papillary thyroid carcinoma. The mean SUVmax of all lesions was 8.5±6.9, most of them being more than 2.5 (n=30). The mean ΔSUVmax was 57.3%±24.6%, indicating different metabolism of the primary cancers in each patient.In our center, SMPC most commonly involved the gastrointestinal tract and adenocarcinomas were the most common pathology type.

To investigate the abnormal cerebral blood flow (CBF) perfusion in patients with internet addiction (IA) and its possible association with IA severity.Thirty-five adolescents who met the criteria for IA and 12 matched healthy volunteers were recruited for (99m)Tc-ethylcysteinate dimer based CBF perfusion imaging with single photon emission tomography (SPET) both at rest and in adenosine-stressed state. Regional CBF (rCBF) was measured and compared between IA subjects and the controls. Correlation analysis between those abnormal rCBF in adenosine-stressed state and the duration of IA was performed.At the resting state, the IA individuals showed significantly increased rCBF in the left mid-frontal gyrus and left angular gyrus, but significantly decreased in the left paracentral lobule, compared to the controls. In adenosine-stressed state, more cerebral regions with abnormal rCBF were identified. Specifically, increased rCBF was identified in the right paracentral lobule, right mid-frontal gyrus and left superior temporal gyrus, while decreased rCBF were demonstrated in right transverse temporal gyrus, left inferior frontal gyrus and left precuneus. Those rCBF in rCBF-increased regions in stress state were positively correlated with the duration of IA, while those in rCBF-decreased regions were negatively correlated with the duration of IA.We present specific functional changes in behaviour that may appear in IA patients related to the CBF findings in IA patients. Adenosine can be used as a pharmacological agent for stress CBF perfusion imaging in patients with IA, by which more cerebral regions of abnormal rCBF can be identified compared to the state at rest. These abnormal rCBF may indicate the neurological mechanism in IA patients.

Intravenous leiomyomatosis (IVL) of the uterus is a rare neoplasm which usually occurs after hysterectomy. Due to its rarity and non-specific clinical manifestations, IVL is commonly misdiagnosed as malignant thrombus or thrombosis and treated inappropriately. Herein, we report an unusual case of a 51 years old woman with IVL without hysterectomy or abdominal manifestations. The IVL was detected in the right atrium. This case highlights the usefulness of (18)F-FDG PET/CT in the diagnosis of IVL.
