Development and validation of a predictive nomogram for lower extremity deep vein thrombosis dislodgement in orthopedic patients.

Objective: To analyze the risk factors of lower extremity deep venous thrombosis (DVT) detachment in orthopedic patients, and to establish a risk nomogram prediction model.

Methods: The clinical data of 334 patients with orthopedic DVT admitted to the Third Hospital of Hebei Medical University from January 2020 to July 2021 were retrospectively analyzed. General statistics included gender, age, BMI, thrombus detachment, inferior vena cava filter window type, filter implantation time, medical history, trauma history, operation, use of tourniquet, thrombectomy, anesthesia mode, anesthesia grade, operative position, blood loss during operation, blood transfusion, immobilization, use of anticoagulants, thrombus side, thrombus range, D-dimer content before filter implantation and during removal of inferior vena cava filter.

A better inferior vena cava filter retrieval rate: A retrospective study in a single-center institution.

Purpose: To determine practice patterns of inferior vena cava filters (IVCFs), retrieval rates, and reasons why retrievable-IVCFs (R-IVCFs) are kept permanent.

Methods: A total of 399 patients who received IVCFs at Third Hospital of Hebei Medical University from January 2017 to December 2017 were registered and retrospectively studied. Date of demographics, baseline medical history, dwell time, reasons why R-IVCFs were kept permanent, and R-IVCFs thrombus were collected.

Characterization and evolution of intestine injury at the anhepatic phase in portal hypertensive rats.

The aim of the present study was to investigate the characteristics and progression of intestinal injury at the anhepatic phase in portal hypertensive rats. A total of 120 healthy male Wistar rats were purchased, with 15 rats in the normal control group and 105 rats were assigned to establish a prehepatic portal hypertension model. The 105 model rats were further divided into seven treatment groups following ischemia-reperfusion.
