Reconstruction of Inferior Vena Cava by Autologous Great Saphenous Vein Grafts in Liver Surgery.

Background: To secure surgical margin for hepatic lesion with involvement of the inferior vena cava (IVC), combined radical liver resection and IVC replacement are required. A novel method of replacing IVC by newly customized autologous great saphenous vein (GSV) grafts was introduced by this study. This study aimed at reporting the feasibility and outcome of this novel technique.

Chest, pericardium, abdomen, and thigh penetrating injury by a steel rebar: A case report.

Background: Combined penetrating trauma involving the chest, pericardium, abdomen, and thigh is rare and lethal. It is difficult to quickly rescue patients with penetrating injuries from long steel bars.

Case Summary: A previously healthy 56-year-old male worker presented with a length of rebar that penetrated the chest-abdomen-pelvic cavity and was palpable on the anterior side of the neck and thigh.

[The Predictive Value of Perioperative Inflammatory Indicatorsin Prognosis of the Intrahepatic Cholangiocarcinoma Patients after Hepatectomy].

Objective: To evaluate the effect of perioperative inflammatory indicators on the prognosis of the patients with intrahepatic cholangiocarcinoma (ICC) after hepatectomy.

Methods: The clinical data of 231 ICC patients in the West China Hospital of Sichuan University from December 2006 to December 2016 were retrospectively collected. Neutrophil-to-lymphocyte ratio (NLR), derived neutrophil-to-lymphocyte ratio (d-NLR) and platelet-to-lymphocyte ratio (PLR) of patients during the perioperative period (pre-operation, postoperative day 3 and day 5) were analyzed.

[Homologous recombination among bacterial genomes: the measurement and identification].

Homologous recombination is one of important sources in shaping the bacterial population diversity, which disrupts the clonal relationship among different lineages through horizontal transferring of DNA-segments. As consequence of blurring the vertical inheritance signals, the homologous recombination raises difficulties in phylogenetic analysis and reconstruction of population structure. Here we discuss the impacts of homologous recombination in inferring phylogenetic relationship among bacterial isolates, and summarize the tools and models separately used in recombination measurement and identification.
