Comparison of clinical outcomes between Castor single-branched stent graft and in situ fenestration in treating Stanford type B aortic dissection involving the left subclavian artery: A retrospective case-control study.

Stanford type B aortic dissection involving the left subclavian artery (LSA) poses significant clinical challenges. The Castor single-branch stent graft and in situ fenestration are commonly used techniques, but the better endovascular treatment remains debated. This study evaluates the clinical effects of the Castor single-branched stent graft versus in situ fenestration in treating Stanford type B aortic dissection involving the LSA.

Intercostal hemangiomas coexisting with multiple hepatic hemangiomas: Clinical and imaging findings in a single case report with a review of the literature.

Rationale: Intercostal hemangioma (IH) is an extremely rare disease, with only 18 cases reported in the past 30 years. Herein, we report the first case of IH coexisting with multiple hepatic hemangiomas, which recurred 32 months after surgery with rib erosion. IHs are invasive and difficult to distinguish from other intercostal tumors on imaging.

Case Report: Combined transcatheter arterial embolization and aortic stent-graft have better efficacy for bronchial artery aneurysms.

Bronchial artery aneurysm (BAA) is a rare and fatal condition that requires immediate treatment. However, conventional surgical and transcatheter arterial embolization treatments are less effective. In the present case, a 76-year-old hypertensive woman was admitted with dizziness and diagnosed with an unruptured bronchial artery aneurysm, which was treated by transcatheter arterial embolization and aortic stent-graft.

Digenic Inheritance of PROC and SERPINC1 Mutations Contributes to Multiple Sites Venous Thrombosis.

Venous thromboembolism (VTE) represents a worldwide health challenge, impacting millions of people each year. The genesis of venous thrombosis is influenced in part by genetic components. Hereditary thrombosis is described as a genetically determined susceptibility to VTE.

Bioinformatics Approach to Identify the Influences of COVID-19 on Ischemic Stroke.

As severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) is becoming more infectious and less virulent, symptoms beyond the lungs of the Coronavirus Disease 2019 (COVID-19) patients are a growing concern. Studies have found that the severity of COVID-19 patients is associated with an increased risk of ischemic stroke (IS); however, the underlying pathogenic mechanisms remain unknown. In this study, bioinformatics approaches were utilized to explore potential pathogenic mechanisms and predict potential drugs that may be useful in the treatment of COVID-19 and IS.

YKL-40 mediates airway remodeling in asthma via activating FAK and MAPK signaling pathway.

YKL-40 is a chitinase-like protein which was significantly elevated in asthma patients and related closely to asthma severity and airway remodeling. Airway remodeling in asthma involves complicated physical and pathological processes, including increased airway smooth muscle mass due to proliferation, migration of airway smooth muscle cells, epithelial-mesenchymal transition (EMT) and sub-epithelial fibrosis. However, the precise effect and underlying mechanism of YKL-40 in this pathological alteration remained unelucidated.

Magnetic and pH dual-responsive mesoporous silica nanocomposites for effective and low-toxic photodynamic therapy.

Nonspecific targeting, large doses and phototoxicity severely hamper the clinical effect of photodynamic therapy (PDT). In this work, superparamagnetic FeO mesoporous silica nanoparticles grafted by pH-responsive block polymer polyethylene glycol--poly(aspartic acid) (PEG--PAsp) were fabricated to load the model photosensitizer rose bengal (RB) in the aim of enhancing the efficiency of PDT. Compared to free RB, the nanocomposites (polyethylene glycol--polyaspartate-modified rose bengal-loaded magnetic mesoporous silica [RB-MMSNs]) could greatly enhance the cellular uptake due to their effective endocytosis by mouse melanoma B16 cell and exhibited higher induced apoptosis although with little dark toxicity.

Hydrophilic mesoporous carbon nanospheres with high drug-loading efficiency for doxorubicin delivery and cancer therapy.

In this study, a highly effective transmembrane delivery vehicle based on PEGylated oxidized mesoporous carbon nanosphere (oMCN@PEG) was successfully fabricated in a facile strategy. oMCN@PEG exhibited a narrow size distribution of 90 nm, excellent hydrophilicity, good biocompatibility, and a very high loading efficiency for doxorubicin (DOX). The drug system (oMCN@DOX@PEG) exhibited excellent stability under neutral pH conditions, but with dramatic releases of DOX at reduced pH conditions.
