Development and validation of a risk prediction model and prediction tools for post-thrombotic syndrome in patients with lower limb deep vein thrombosis.

Purpose: Our research aims to compare the predictive performance of decision tree algorithms (DT) and logistic regression analysis (LR) in constructing models, and develop a Post-Thrombotic Syndrome (PTS) risk stratification tool.

Methods: We retrospectively collected and analyzed relevant case information of 618 patients diagnosed with DVT from January 2012 to December 2021 in three different tertiary hospitals in Jiangxi Province as the modeling group. Additionally, we used the case information of 212 patients diagnosed with DVT from January 2022 to January 2023 in two tertiary hospitals in Hubei Province and Guangdong Province as the validation group.

Lathyrane diterpenoids from and their antitumor activities in human osteosarcoma cells.

Two new lathyrane-type diterpenoids, jatropodagins A and B ( and ), and five known analogues (-), were isolated from the stems of . Their structures and absolute configurations were elucidated by spectroscopic data and calculated ECD analyses. The cytotoxicities of all the lathyrane-type diterpenoids (-) were evaluated against two human osteosarcoma cell lines (Saos-2 and MG-63).

[The influence of oil heat treatment on wood decay resistance by Fourier infrared spectrum analysis].

Wood preservative treatment can improve defects of plantation wood such as easy to corrupt and moth eaten. Among them heat-treatment is not only environmental and no pollution, also can improve the corrosion resistance and dimension stability of wood. In this test Poplar and Mongolian Seoteh Pine was treated by soybean oil as heat-conducting medium, and the heat treatment wood was studied for indoor decay resistance; wood chemical components before and after treatment, the effect of heat treatment on wood decay resistance performance and main mechanism of action were analysed by Fourier infrared spectrometric.

Adhesion molecule CD146 and its soluble form correlate well with carotid atherosclerosis and plaque instability.

Aims: Intraplaque neovascularization and foam cell infiltration contribute to the development of unstable plaque, leading to thromboembolism and stroke. Cell adhesion molecules (CAMs) have been reported to be involved in the progression of atherosclerosis and plaque vulnerability. The aim of this study was to assess the association of adhesion molecule CD146 with carotid plaque instability.

[Association between both triglyceride level, newly identified carotid plaque and middle-aged and elderly population, Beijing].

Objective: To evaluate the association between triglyceride (TG) level and newly identified 5-year carotid plaque and to explore the prediction value of TG level on the newly-identified carotid plaque with risk factors of traditional atherosclerosis.

Methods: A cohort study was adopted. The baseline survey including CVD risk factors and B-mode ultrasound of carotid artery was performed in 2002, and the second follow-up examination was performed in 2007.

Characteristics and risk factors of cerebrovascular accidents after percutaneous coronary interventions in patients with history of stroke.

Background: Percutaneous coronary intervention (PCI) is a well-established method for managing coronary diseases. However, the increasing use of PCI has led to an increased incidence of acute cerebrovascular accidents (CVA) related to PCI. In this study, we investigated the characteristics and risk factors of CVA after PCI in patients with known stroke history.
