Adhesive hydrogels have been considered as one of the most ideal materials for wound dressing. However, existing adhesive still disadvantages such low mechanical properties, poor biological activity (antibacterial and hemostatic ability), biocompatibility, which largely limit their application. Thus, it is highly desired to prepare a hydrogel-based dressing with good self-healing, rapid hemostasis, excellent infection prevention activity. In this study, simple method was presented...

Limb ischemia is a refractory disease characterized by persistent inflammation, insufficient angiogenesis, and tissue necrosis. Although mesenchymal stem cells (MSCs) have shown potential for treating limb ischemia, their therapeutic effects are limited low engraftment rates. Therefore, developing an optimal MSC delivery system that enhances cell viability imperative. Selenium, known its cytoprotective properties in various types, offers strategy to enhance effect of MSCs. In this study, we...

Abstract Background The specific role of lysophosphatidic acid 2 (LPA ) in deep vein thrombosis (DVT) remains unclear. Methods An inferior vena cava annulus retraction model DVT was established wild-type (WT) and global LPA knockout ( Lpar2 −/− mice. We examined the incidence DVT, wet weight thrombus, length assessed endothelial permeability through Evans blue dye assay vivo, cell viability, (EC) mouse ECs vitro. Proteomics, histopathology, immunohistochemistry, western blotting were...

Background The permanent placement of inferior vena cava (IVC) filters may lead to numerous complications and their removal is recommended once the risk pulmonary embolism reduced. Removal IVC by endovenous means preferred. But failure happens when recycling hooks penetrate vein wall are left in place for too long time. In these scenarios, open surgery be effective filters. We aimed describe surgical approach, outcomes, 6-month follow-up filter surgery, after via method. Methods A total...

In the course of our investigations new sources higher plant lipids, seed fatty acid compositions and tocochromanol contents Salvia bracteata, S. euphratica var. euphratica, aucherii canascens, cryptantha, staminea, limbata, virgata, hypargeia, halophylla, syriaca cilicica were investigated using GLC HPLC systems. Some species are endemic to Turkey. All sp. showed same pattern acids. Linoleic, linolenic oleic found as abundant components. Tocochromanol derivatives oil differences between...

The inferior vena cava filter is utilized worldwide to intercept thrombi and reduce the risk of fatal pulmonary embolism (PE). However, filter-related thrombosis a complication implantation. Endovascular methods such as AngioJet rheolytic thrombectomy (ART) catheter-directed thrombolysis (CDT) can treat caval thrombosis, but clinical outcomes both treatment modalities have not been determined.To compare vs in patients with thrombosis.In this single-center retrospective study, 65 (34 males 31...

In orthopedic trauma, identification of extremity trauma combined with vascular injury is challenging. Missed diagnosis may result in amputation or even death. The purpose this study was to investigate whether physical examination handheld ultrasound Doppler could be an effective method screening for peripheral and explore the characteristics injuries patients.

Two unusual monoterpenes, densispicnins A (1), B (2), together with the four known mussaenoside (3), yuheinoside (4), mussaenin (5), argyol (6), were isolated from whole plant of Pedicularis densispica Franch.The structures 1 and 2 elucidated mainly based on spectral data including 1D-, 2D-NMR (HSQC, HMBC, ROESY) MS experiments.

Abstract The isolation, structure elucidation, and antitumor activity of four new sesquiterpene polyol esters, i.e. , 6 α ,13‐bis(acetyloxy)‐9 β ‐(cinnamoyloxy)‐1 ‐(furan‐3‐ylcarbonyl)oxy]‐4 ‐hydroxy‐ ‐dihydroagarofuran ( 1 ), 13‐(acetyloxy)‐9 ‐(benzoyloxy)‐4 ‐hydroxy‐1 ,6 ‐bis[(2‐methylbutanoyl)oxy]‐ 2 ,13‐ tri(acetyloxy)‐9 ‐(cinnamoyloxy)‐4 3 ‐[(2‐methylbutanoyl)oxy]‐ 4 five known esters 5 – 9 from the seed oil Euonymus nanoides Loes. are reported...

Abstract A new nortriterpene, 2‐hydroxy‐3‐methyl‐21‐oxo‐12,24‐dinor‐ D : B ‐friedooleana‐1,3,5(10),7‐tetraen‐29‐oic acid ( 1 ), was isolated from the root of Celastrus hypoleucus , together with two known compounds, celastorol 2 ) and pristimerine 3 ). Their structures were elucidated on basis spectroscopic analyses. Compounds – exhibited in vitro significant antioxidant (against lipid peroxidation; by TBARS method) antitumor activities cancer cell lines P‐388, A‐549, HL‐60, BEL‐7402).

To discuss and share the experience of treatment traumatic innominate arterial injury. A retrospective analysis was performed on patients with injuries admitted from January 2016 to July 2018 at department vascular surgery, Beijing Jishuitan Hospital, China. All were confirmed by arteriography. Clinical data including mechanism injury, type demographics, concomitant injuries, time interval trauma blood flow reconstruction, operation methods collected. Follow-up program included outpatient...

To explore the significance of traditional vascular reconstruction and covered stent for limb salvage after subclavian artery injury. Patients with injury admitted to Beijing Jishuitan Hospital from January 2010 December 2018 were retrospectively analyzed. All injuries have been confirmed by intraoperative exploration, computed tomography angiography or digital subtraction angiography. Complete partial amputation excluded. Mild defect intimal damage was treated interventional implantation,...

PURPOSE We aimed to examine the efficacy and safety of Tempofilter II (B. Braun, Melsungen, Germany) implantation prevent pulmonary embolism in patients with lower-extremity fractures proximal deep vein thrombosis (DVT). MATERIALS AND METHODS The records lower limb DVT who were implanted devices from May 2004 August 2009 reviewed. Data collected included success rate, occurrence embolism, retrieval complications. RESULTS A total 176 eligible patients, including 129 males (73.3%) 47 females...

We report the case of a 22-year-old male who underwent endoluminal surgery and was implanted an Option Elite filter in superior vena cava (SVC) while retraction hook attached to vessel wall. The patient requested remove after 155 days. Preoperative ultrasonography CT examination revealed that very likely penetrate SVC wall its tip close right pulmonary artery. not obstructed, no thrombus observed either upper limb. After retrieval device (ZYLOX, China) failed capture hook, we introduced...
