1Laparoscopic 肝切除术: 当前的角色和限制显示文摘 Laparoscopic liver resection (LLR) for the treatment of benign and malignant liver lesions is often performed at specialized centers. Technological advances, such as laparoscopic ultrasonography and electrosurgical tools, have afforded surgeons simultaneous improvements in surgical technique. The utilization of minimally invasive techniques for liver resection has been reported to reduce operative time, decrease blood loss, and shorten length of hospital stay with equivalent postoperative mortality and morbidity rates compared to open liver resection (OLR). Non-anatomic liver resection and left lateral sectionectomy are now routinely performed laparoscopically at many institutions. Furthermore, major hepatic resections are performed by pure laparoscopy, hand-assisted technique, and the hybrid method. In addition, robotic surgery and single port surgery are revealing early promising results. The consensus recommendation for the treatment of benign liver disease and malignant lesions remains unchanged when considering a laparoscopic approach, except when comorbidities and anatomic limitations of the liver lesion preclude this technique. Disease free and survival rates after LLR for hepatocellular carcinoma and metastatic colon cancer correspond to OLR. Patient selection is a significant factor for these favorable outcomes. The limitations include LLR of superior and posterior liver lesions; however, adjustments in technique may now consider a laparoscopic approach as a viable option. As growing data continue to reveal the feasibility and efficacy of laparoscopic liver surgery, this skill is increasingly being adopted by hepatobiliary surgeons. Although the full scope of laparoscopic liver surgery remains infrequently used by many general surgeons, this technique will become a standard in the treatment of liver diseases as studies continue to show favorable outcomes.Rouzbeh Mostaedi Zoran Milosevic Ho-Seong Han Vijay P Khatri 2012World Journal of Gastrointestinal Oncology2012,4,8:8
2Adenosquamous carcinoma of the pancreas: Molecular characterization of 23 patients along with a literature review显示文摘Adenosquamous carcinoma of the pancreas(ASCP)is a rare entity. Like adenocarcinoma of the pancreas,overall survival is poor. Characteristics of ASCP include central tumor necrosis, along with osteoclasts and hypercalcemia. Various theories exist as to why this histological subtype exists, as normal pancreas tissue has no benign squamous epithelium. Due to the rarity of this disease, limited molecular analysis has been performed, and those reports indicate unique molecular features of ASCP. In this paper, we characterize 23 patients diagnosed with ASCP through molecular profiling using immunohistochemistry staining, fluorescent in situ hybridization, chromogenic in situ hybridization, and gene sequencing, Additionally, we provide a comprehensive literature review of what is known to date of ASCP.Molecular characterization revealed overexpression in MRP1(80%), MGMT(79%), TOP2A(75), RRM1(42%),TOPO1(42%), PTEN(45%), CMET(40%), and C-KIT(10%) among others. One hundred percent of samples tested were positive for KRAS mutations. This analysis shows heretofore unsuspected leads to be considered for treatments of this rare type of exocrine pancreas cancer. Molecular profiling may be appropriate to provide maximum information regarding the patient's tumor. Further work should be pursued to better characterize this disease.Erkut Borazanci Sherri Z Millis Ron Korn Haiyong Han Clifford J Whatcott Zoran Gatalica Michael T Barrett Derek Cridebring Daniel D Von Hoff 2015World Journal of Gastrointestinal Oncology2015,7,9:6

4Single-cell profiling reveals the trajectories of natural killer cell differentiation in bone marrow and a stress signature induced by acute myeloid leukemia显示文摘Natural killer(NK)cells are innate cytotoxic lymphoid cells(ILCs)involved in the killing of infected and tumor cells.Among human and mouse NK cells from the spleen and blood,we previously identified by single-cell RNA sequencing(scRNAseq)two similar major subsets,NK1 and NK2.Using the same technology,we report here the identification,by single-cell RNA sequencing(scRNAseq),of three NK cell subpopulations in human bone marrow.Pseudotime analysis identified a subset of resident CD56^(bright) NK cells,NK0 cells,as the precursor of both circulating CD56dim NK1-like NK cells and CD56^(bright) NK2-like NK cells in human bone marrow and spleen under physiological conditions.Transcriptomic profiles of bone marrow NK cells from patients with acute myeloid leukemia(AML)exhibited stress-induced repression of NK cell effector functions,highlighting the profound impact of this disease on NK cell heterogeneity.Bone marrow NK cells from AML patients exhibited reduced levels of CD160,but the CD160high group had a significantly higher survival rate.Adeline Crinier Pierre-Yves Dumas Bertrand Escalière Christelle Piperoglou Laurine Gil Arnaud Villacreces Frédéric Vély Zoran Ivanovic Pierre Milpied Émilie Narni-Mancinelli Éric Vivier 2021Cellular & Molecular Immunology2021,18,5:5
5Monoclonal immunoscintigraphy for detection of metastasis and recurrence of colorectal cancer显示文摘AIM:To assess the clinical role of monoclonal immunoscintigraphy for the detection of metastasis and recurrence of colorectal cancer.METHODS:Monoclonal immunoscintigraphy was performed in patients operated on for colorectal adenocar-cinoma suspected of local recurrence and metastatic disease.The results were compared with conventional diagnostics.RESULTS:Immunoscintigraphic investigation was done in 53 patients.Tumor recurrence occurred in 38 patients,and was confirmed by other diagnostic modalities in 35.In 15 patients,immunoscintigraphic findings were negative,and confirmed in 14 with other diagnostic methods.Comparative analysis confirmed good correlation of immunoscintigraphic findings and the results of conventional diagnostics and the level of tumor marker carcinoembryonic antigen.Statistical analysis of parameters of radiopharmaceutical groups imacis,indimacis and oncoscint presented homogenous characteristics all of three radiopharmaceuticals.The analysis of immunoscintigraphic target focus was clearly improved using tomography.CONCLUSION:Immunoscintigraphy is highly specific and has a good predictive value in local recurrence of colorectal cancer.Vera Artiko Ana Koljevic Markovi Dragana obi-aranovi Milorad Petrovi Andrija Anti Mirjana Stojkovi Marinko Zuvela Djordjije aranovi Milica Stojkovi Neboja Radovanovi Danijel Galun Aleksandar Milovanovi Jovica Milovanovi Anica Bobi-Radovanovi Zoran Krivokapic Vladimir Obradovi 2011World Journal of Gastroenterology2011,17,19:4
6Four-dimensional flow magnetic resonance imaging incirrhosis显示文摘Since its introduction in the 1970’s,magnetic resonance imaging(MRI)has become a standard imaging modality.With its broad and standardized application,it is firmly established in the clinical routine and an essential element in cardiovascular and abdominal imaging.In addition to sonography and computer tomography,MRI is a valuable tool for diagnosing cardiovascular and abdominal diseases,for determining disease severity,and for assessing therapeutic success.MRI techniques have improved over the last few decades,revealing not just morphologic information,but functional information about perfusion,diffusion and hemodynamics as well.Four-dimensional(4D)flow MRI,a time-resolved phase contrast-MRI with three-dimensional(3D)anatomic coverage and velocity encoding along all three flow directions has been used to comprehensively assess complex cardiovascular hemodynamics in multiple regions of the body.The technique enables visualization of 3D blood flow patterns and retrospective quantification of blood flow parameters in a region of interest.Over the last few years,4D flow MRI has been increasingly performed in the abdominal region.By applying different acceleration techniques,taking 4D flow MRI measurements has dropped to a reasonable scanning time of 8 to 12 min.These new developments have encouraged a growing number of patient studies in the literature validating the technique’s potential for enhanced evaluation of blood flow parameters within the liver’s complex vascular system.The purpose of this review article is to broaden our understanding of 4D flow MRI for the assessment of liver hemodynamics by providing insights into acquisition,data analysis,visualization and quantification.Furthermore,in this article we highlight its development,focussing on the clinical application of the technique.Zoran Stankovic 2016World Journal of Gastroenterology2016,22,1:4

9Hematopoietic stem cells in research and clinical applications:The“CD34 issue”显示文摘In this paper,experimental findings concerning the kinetics of hematopoietic reconstitution are compared to corresponding clinical data.Although not clearly apparent,the transplantation practice seems to confirm the basic proposals of experimental hematology concerning hematopoietic reconstitution resulting from successive waves of repopulation stemming from different subpopulations of progenitor and stem cells.One of the 'f irst rate' parameters in clinical transplantations in hematology;i.e.the CD34+ positive cell dose,has been discussed with respect to the functional heterogeneity and variability of cell populations endowed by expression of CD34.This parameter is useful only if the relative proportion of stem and progenitor cells in the CD34+ cell population is more or less maintained in a series of patients or donors.This proportion could vary with respect to the source,pathology,treatment,processing procedure,the graft ex vivo treatment and so on.Therefore,a universal dose of CD34+ cells cannot be def ined.In addition,to avoid further confusion,the CD34+ cells should not be named 'stem cells' or 'progenitor cells' since these denominations only concern functionally characterized cell entities.Zoran Ivanovic 2010World Journal of Stem Cells2010,2,2:3

14Comparison of light absorption and oxidative potential of biodiesel/diesel and chemicals/diesel blends soot particles显示文摘Soot particles,mainly coming from fuel combustion,affect climate forcing through absorbing light and also result in adverse human health outcomes.Though biodiesel or additives blending with diesel was considered environmentally friendly,the understanding on absorbing and oxidative capacity of soot emitted from them are still unclear.The watersoluble organic carbon(WSOC)content,surface chemical structure,light absorption and oxidative potential(OPDTT)of soot from biodiesel/diesel and chemicals/diesel blends were investigated utilizing total organic carbon analyzer,X-ray photoelectron spectrometer,ultraviolet–visible spectrophotometry and dithiothreitol(DTT)assay.The differences and correlations between soot properties were statistically analyzed.Chemicals/diesel blends soot owned significantly higher WSOC content,ratio of mass absorbing efficiency(MAE)in250 and 365 nm(E2/E3),OPDTT,and higher surface carbonyl content.Coconut biodiesel/diesel blends soot contained evidently higher aromatic carbon–oxygen single bond(ArC–O)content,and higher MAE365.The individual comparison of biodiesel/diesel blends showed20%coconut biodiesel blend owned the lowest WSOC,E2/E3 and OPDTT,while highest ArC–O and MAE365,representing strongest absorbing properties.Association analysis showed OPDTTwas significantly positively correlated with WSOC.Further,the evident negative correlation between MAE365 and OPDTT was observed.Our results showed coconut biodiesel/diesel blends soot induced lower levels of oxidative potential,whereas absorption of light was higher,which have far reaching consequences on climate forcing.Therefore,it is important to evaluate the balance point between light-absorbing properties and oxidative potential,under the wide use of biodiesel.Yu Kuang Yi Guo Jiaqi Chai Jing Shang Jiali Zhu Svetlana Stevanovic Zoran Ristovski 2020Journal of Environmental Sciences2020,32,1:2

17Adenosquamous carcinoma arising within a retrorectal tailgut cyst: Report of a case显示文摘Retrorectal, developmental tail gut cysts, include dermoid cysts, rectal duplication cysts and retrorectal cyst-hamartomas. Retrorectal cyst-hamartomas (RCH) are derived from remnants of the tail gut, the most caudal part of the embryonic hind gut, which normally involutes by the 8th wk of embryonic development (3-8 mm stage). They have specific radiological and histopathological features that distinguish them from other similar formations (dermoid cysts, enteric duplication cysts and teratomas). We report a patient with adenosquamous carcinoma arising within RCH, who underwent complete resection of the cyst through anterior laparotomy, and reached complete (recurrencefree for 14 mo, so far) functional recovery. The cyst was incidentally discovered during hysterectomy 12 years ago.Diagnostic, therapeutic and histopathological aspects of this rare case are discussed. The mentioned period between diagnosis and surgical treatment suggests that RCH, given enough time, can develop malignant degeneration, and should be resected at the time of diagnosis.Zoran Krivokapic Ivan Dimitrijevic Goran Barisic Velimir Markovic Miodrag Krstic 2005World Journal of Gastroenterology2005,11,39:2
