Metastasis remains one of the major challenges before hepatocellular carcinoma (HCC) is finally conquered. This paper summarized a decade’s studies on HCC metastasis at the Liver Cancer Institute of Fudan University. We have established a stepwise metastatic human HCC model system, which included a metastatic HCC model in nude mice (LCI-D20), a HCC cell(More)
PURPOSE Describe the prevalence of visual impairment/blindness among older adults in rural populations in China. DESIGN Population-based, cross-sectional study. PARTICIPANTS We evaluated 45 747 adults > or =50 years of age. METHODS Geographically defined cluster sampling was used in randomly selecting a cross-section of residents from a representative(More)
We used functional magnetic resonance imaging (fMRI) to measure functional connectivity of the dentate nucleus (DN) between patients with Parkinson's disease (PD) and normal controls who were studied in a resting state. Images were acquired in 18 PD patients and in age- and sex-matched normal controls. Connectivity of the bilateral DN was calculated and(More)
BACKGROUND Hepatocellular carcinoma (HCC) is a common and aggressive form of cancer. Due to a high rate of postoperative recurrence, the prognosis for HCC is poor. Subclinical metastasis is the major cause of tumor recurrence and patient mortality. Currently, there is no reliable prognostic method of invasion. AIM To investigate the feasibility of(More)
OBJECTIVES The spontaneous low frequency fluctuations (LFF) of blood oxygenation level-dependent (BOLD) signal in resting state have been identified as a biological measure of baseline spontaneous activity in the brain. Increasingly, studies of spontaneous resting state functional connectivity have demonstrated neural network abnormalities in bipolar(More)
BACKGROUND Exposure of high dose ionizing radiation is lethal. Signal pathways involved in radiation biology reaction still remain illdefined. Lipopolysaccharides (LPS), the ligands of Toll-like receptor 4(TLR4), could elicit strong immune responses. Glycogen synthase kinase-3β(GSK-3β) promotes the production of inflammatory molecules and cell migration.(More)
RNA interference (RNAi) is a powerful tool to silence gene expression. Small interfering RNA (siRNA)-induced RNA degradation has been recently used as an antivirus agent to inhibit specific virus replication. Here, we showed that several siRNAs specific for conserved regions of influenza virus matrix (M2) and nucleocapsid protein (NP) genes could(More)
BACKGROUND MicroRNAs (miRNAs) are small, single-stranded, noncoding RNAs, which usually bind to the 3'-untranslated region of target mRNAs and are capable of inducing posttranscriptional gene regulation by blocking translation or by degrading the target mRNA. However, the expression level of miR-23 in radiation induced carcinogenesis is largely unknown. (More)
Due to state-of-art analytical techniques, non-invasive exhaled volatile organic compounds (VOCs) analysis has become a potential method for early diagnosis of lung cancer. We collected breath samples from 43 patients with non-small cell lung cancer (NSCLC) and 41 normal controls using Tedlar gas bags. The VOCs were extracted with solid phase(More)
Diffusion-weighted MRI (DWI) has been proposed as a method to evaluate the integrity of white matter tracts in the spinal cord. The integrity of the spinal cord reflects the exact stage of traumatic injury. The purpose of this study was to evaluate the diagnostic value of DWI in SCIWORA in the thoracic spine. A total of five patients with thoracic SCIWORA(More)
