  • MUC4 Research Progress in Tumor Molecular Markers

    Mucin antigen 4 (MUC4) is a molecular marker for some malignant tumors for early tumor diagnosis, prognosis and targeted therapy. It provides a new research direction in tumor diagnosis and treatment that will have a wide application prospect. In recent years, there has been a large number of research reports on the basic and clinical studies about MUC4, but the molecular imaging study about MUC4 is seldom reported. In this paper the recent research about MUC4 on basic and clinical studies is briefly reviewed, and it is expected to promote the development of tumor molecular imaging.

  • Bibliometric and Research Hotspots Analysis of Pancreatic Neoplasms and Molecular Imaging in Recent Five Years

    ObjectiveTo investigate researches on pancreatic neoplasms and molecular imaging in recent five years and provide reference information for the majority of professionals in deep research. MethodsBibliographies from research literature of pancreatic neoplasms and molecular imaging in recent five years in PubMed database were downloaded. The publication years, journals, countries of publication, the first authors and the frequency of MJMEs were counted by Bicomb 2.0 software. The affiliations were analyzed artificially. MJMEs appeared no less than two times were intercepted as high frequency ones and the high frequency MJMEs co-occurrence matrix were formed. SPSS 22.0 statistical software were applied for clustering analysis with matrix, then to get the topic hotspots. ResultsA total of 28 literatures were screened out. The data of research trend, journals, research degree of countries were acquired. The number of high frequency MJMEs were 20 and among which 5 research hotspots were clustered. ConclusionsResearches on pancreatic neoplasms and molecular imaging are mainly in terms of therapy and genetics, diagnosis and metabolism, radionuclide imaging, pharmacology and pathology.

  • Application of different molecular imaging techniques in predicting the progress of abdominal aortic aneurysm

    Abdominal aortic aneurysm (AAA) is a common lethal aortic disease in clinical practice. At present, the imaging diagnostic methods used for AAA mainly include Doppler ultrasound, computed tomography and magnetic resonance imaging (MRI), but these methods can only observe the morphological changes of the aorta. These techniques used for the risk assessment of aneurysms, such as aneurysm rupture have some certain limitations. With the continuous development of molecular imaging technology and the further understanding of the pathogenesis of AAA, positron emission tomography (PET), molecular MRI and single photon emission computed tomography (SPECT) techniques can be used to observe the pathological changes of the AAA and assess the risk of rupture from cell and molecular level. In this paper, the latest application of PET, molecular MRI, SPECT in the risk assessment was discussed.
