Thrombocytosis as a prognostic marker in gastrointestinal cancers

引用

World Journal of Gastrointestinal Oncology 2014年第2期6卷 34-40页

作者： ioannis A Voutsadakis Division of Medical Oncology Sault Area Hospital

Thrombocytosis is an adverse prognostic factor in many types of cancer. These include breast cancer, ovarian and other gynecologic cancers, renal cell carcinoma and lung cancers. In gastrointestinal cancers of various locations and histologic types, thrombocytosis has been reported in general to be associated with adverse clinical outcomes. Platelet count measurement is well standardized and available in every clinical laboratory, making its use as a prognostic marker practical. This paper will discuss the data on the prognostic value of thrombocytosis in gastrointestinal cancers as well as pathogenic aspects of the association that strengthen the case for its use in clinical prognostication.

Landscape of BRIP1 molecular lesions in gastrointestinal cancers from published genomic studies

World Journal of Gastroenterology 2020年第11期26卷 1197-1207页

BACKGROUND BRIP1 is a helicase that partners with BRCA1 in the homologous recombination(HR) step in the repair of DNA inter-strand cross-link lesions. It is a rare cause of hereditary ovarian cancer in patients with no mutations of BRCA1 or BRCA2. The role of the protein in other cancers such as gastrointestinal(GI) carcinomas is less well characterized but given its role in DNA repair it could be a candidate tumor suppressor similarly to the two BRCA *** To analyze the role of helicase BRIP1(FANCJ) in GI cancers *** Publicly available data from genomic studies of esophageal, gastric, pancreatic,cholangiocarcinomas and colorectal cancers were interrogated to unveil the role of BRIP1 in these carcinomas and to discover associations of lesions in BRIP1 with other more common molecular defects in these *** Molecular lesions in BRIP1 were rare(3.6% of all samples) in GI cancers and consisted almost exclusively of mutations and amplifications. Among mutations,40% were possibly pathogenic according to the Onco KB database. A majority of BRIP1 mutated GI cancers were hyper-mutated due to concomitant mutations in mismatch repair or polymerase ε and δ1 genes. No associations were discovered between amplifications of BRIP1 and any mutated genes. In gastroesophageal cancers BRIP1 amplification commonly co-occurs with ERBB2 *** Overall BRIP1 molecular defects do not seem to play a major role in GI cancers whereas mutations frequently occur in hypermutated carcinomas and co-occur with other HR genes mutations. Despite their rarity, BRIP1 defects may present an opportunity for therapeutic interventions similar to other HR defects.

A historical evaluation of Chinese tongue diagnosis in the treatment of septicemic plague in the pre-antibiotic era, and as a new direction for revolutionary clinical research applications

Journal of Integrative Medicine 2018年第3期16卷 141-146页

作者： ioannis Solos Yuan Liang Department of Orthopedics and Traumatology Guangzhou Zhongxing Sports Trauma Hospital Institute of Basic Theory in Chinese Medicine China Academy of Chinese Medical Sciences

Chinese tongue diagnosis was initially developed to quickly and efficiently diagnose and prescribe medicine, while at the same time allowing the doctor to have minimal contact with the patient. At the time of its compiling, the spread of Yersinia pestis, often causing septicaemia and gangrene of the extremities,may have discouraged doctors to come in direct contact with their patients and take the ***, in recent decades, modern developments in the field of traditional Chinese medicine, as well as the spread of antibiotics in conjunction with the advancements of microbiology, have overshadowed the original purpose of this methodology. Nevertheless, the fast approaching post-antibiotic era and the development of artificial intelligence may hold new applications for tongue diagnosis. This article focuses on the historical development of what is the world＇s earliest tongue diagnosis monograph, and discusses the directions that such knowledge may be used in future clinical research.

Quaternary Neotectonic Configuration of the Southwestern Peloponnese, Greece, Based on Luminescence Ages of Marine Terraces

引用

Journal of Earth Science 2013年第3期24卷 410-427页

作者： Constantin Athanassas ioannis Fountoulis Laboratory of Archaeometry Institute of Materials Science N.C.S.R.'Demokritos' Department of Dynamic Tectonic and Applied Geology Faculty of Geology and Geoenvironment National and Kapodistrian University of Athens

This project studies marine terraces in western Messenia, southwestern Peloponnese, Greece, to propose a model of neotectonic configuration and paleogeographic evolution of western Messenia during the Quaternary. GIS analysis of topographic data and geological mapping revealed flanks of raised terraces created on Quaternary marine deposits. Luminescence ages of sediments from the three westernmost marine terraces tend to be consistent OIS-5, OIS-7 and OIS-9, respectively, thus agreeing with the three latest warm stages of the Pleistocene. Moreover, the type and the extent of deformation of the dated marine terraces allowed us to reflect on the neotectonic configuration of western Messenia as well as to conclude that progressive differential uplift over the last 300 ka has induced a dome-like structure to the upper crust of western Messenia.
