Arteriosclerosis obliterans

In this study, we investigated the impact of microRNA-34a (miR-34a) on lower limb arteriosclerosis obliterans in rats through the Sirtuin 1 (Sirt1) signaling pathway. Thirty-six Sprague-Dawley rats were divided into normal, model, and miR-34a mimics groups. Rats in the normal group were raised normally, while the model group underwent lower limb arteriosclerosis obliterans induction and received saline injections. The miR-34a mimics group also underwent arteriosclerosis obliterans modeling but received miR-34a mimics injections...

Since 2013, the Japanese Society for Vascular Surgery has started the project of nationwide registration and tracking database for patients with critical limb ischemia (CLI) who are treated by vascular surgeons. The purpose of this project is to clarify the current status of the medical practice for the patients with CLI to contribute to the improvement of the quality of medical care. This database, called JAPAN Critical Limb Ischemia Database (JCLIMB), is created on the National Clinical Database and collects data of patients' background, therapeutic measures, early results, and long-term prognosis as long as 5 years after the initial treatment...

BACKGROUND: The pathological damage mechanism of type 2 diabetes (T2D) and macroangiopathy is extremely complex, and T2D and arteriosclerosis obliterans have different biological behaviors and clinical features. To explore the mechanism of lower extremity arteriosclerosis occlusion (LEAOD) in T2D patients, we utilized RNA-seq to identify unique gene expression signatures of T2D and LEAOD through transcriptomic analysis. METHODS: We obtained blood samples and performed RNA sequencing from four patients with T2D, five of whom had LEAOD...

This study aimed to decipher the mechanism of circular ribonucleic acids (circRNAs) in lower extremity arteriosclerosis obliterans (LEASO). First, bioinformatics analysis was performed for screening significantly down-regulated cardiac specific circRNA-circHAT1 in LEASO. The expression of circHAT1 in LEASO clinical samples was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The protein expression of splicing factor arginine/serine-rich 1 (SFRS1), α-smooth muscle actin (α-SMA), Calponin (CNN1), cyclin D1 (CNND1) and smooth muscle myosin heavy chain 11 (SMHC) in vascular smooth muscle cells (VSMCs) was detected by Western blotting...

Low-density lipoprotein apheresis (LDL-A) is a blood purification therapy used to treat refractory ulcers in patients with arteriosclerosis obliterans. We describe a case of vancomycin treatment in a patient undergoing maintenance hemodialysis and LDL-A therapy and assess its impact on serum vancomycin concentration. The patient underwent LDL-A twice a week (Mondays and Fridays) and maintenance dialysis three times a week (Tuesdays, Thursdays, and Saturdays) for diabetic nephropathy associated with type 1 diabetes mellitus...

This clinical study mainly analyzed the correlation of changes in serum inflammatory factors (IFs), such as matrix metalloproteinase (MMP)-9, hypersensitive C-reactive protein (hs-CRP), tumor necrosis factor (TNF)-α, and interleukin (IL)-6 with post-percutaneous transluminal angioplasty (PTA)acute myocardial infarction (AMI) in coronary heart disease (CHD)patients complicated by lower extremity arteriosclerosis obliterans (ASO). This retrospective study selected sixty ASO+CHD patients (ASO group) who underwent lower limb angioplasty between January 2014 and June 2016, as well as 50 concurrent healthy controls (HCs, HC group)...

OBJECTIVE: Oxidative damage is observed in the ischemic limbs of patients with arteriosclerosis obliterans. We investigated whether pemafibrate, a selective peroxisome proliferator-activated receptor alpha modulator, reduced oxidative stress in ischemic limbs and consequently rescued limb damage in model mice. MATERIALS AND METHODS: We surgically induced hind-limb ischemia in mice and orally administered pemafibrate solution (P-05 group, 0.5 mg/kg/day; P-10 group, 1...

OBJECTIVE: The study aimed to compare the effectiveness of drug-coated balloon (DCB) and drug-eluting stents (DESs) to standard endovascular techniques like percutaneous transluminal angioplasty (PTA) and bare metal stent (BMS) for treating infrapopliteal artery disease. METHODS: Including 8 DCB trials and 4 DES trials, this meta-analysis of 12 recent randomized controlled trials (RCTs) is comprehensive. We searched MEDLINE, EMBASE, Science of Web, Cochrane, and PubMed for this meta-analysis...

BACKGROUND: Endoluminal interventions have become one of the main options for the treatment of arteriosclerosis obliterans (ASO). OBJECTIVE: To explore the effect of hydration therapy and nursing intervention on the prevention of contrast-induced nephropathy (CIN) after interventional treatment of lower extremity ASO. METHODS: A convenience sampling method was used to select 94 patients who received ASO treatment in our hospital from March 2019 to May 2021 as the study subjects...

INTRODUCTION: Orthotopic kidney transplantation is an option when heterotopic kidney transplantation into the iliac fossa is inappropriate. We report a case of orthotopic kidney transplantation following stenting of both external iliac arteries to treat arteriosclerosis obliterans. CASE PRESENTATION: A 56-year-old woman on hemodialysis for end-stage kidney disease underwent living-donor kidney transplantation. Desensitization therapy was administered because of her history of sensitization by pregnancy...

BACKGROUND: Arteriosclerosis obliterans (ASO) is the leading cause of nontraumatic lower-extremity amputations. Multiple researches have suggested that circular RNAs (circRNAs) played vital regulatory functions in cancer and cardiovascular disease. Nevertheless, the underlying effect and pathological mechanism of circRNAs in the formation and progression of ASO are still indistinct. METHODS AND RESULTS: This study used microarray analysis to investigate the expression portrait of circRNAs in normal lower extremity arteries and ASO arteries...

An increasing number of studies have shown that noncoding RNAs are involved in cardiovascular diseases. Our study shows that the expression of microRNA-30a-3p (miR-30a-3p) in patients with arteriosclerosis obliterans (ASO) of the lower extremities is significantly decreased after endovascular treatment, but its role is unclear. This study aims to explore the role of microRNA-30a-3p in ASO and its related mechanisms. Immunofluorescence and in situ hybridization costaining indicated that microRNA-30a-3p mostly exists in vascular smooth muscle cells (VSMCs)...

OBJECTIVE: To explore the effect of a health (E)-coach chronic disease management model on the rehabilitation behaviour management of patients with arteriosclerosis obliterans (ASO). METHODS: The E-coach chronic disease management model was constructed based on a literature review and expert interviews. The effect of the E-coach model on patients with ASO during hospitalisation was analysed by comparing the compliance rates of blood glucose control, blood pressure control, drug compliance, ankle-brachial index, 6-min walking test (6MWT) and pain-free walking distance (PFWD) scores between the E-coach and control groups...

Introduction The disease arteriosclerosis obliterans (ASO) affects the lower extremities. ASO's mechanism involves the proliferation and migration of vascular smooth muscle cells (VSMCs). The miR-4284 is involved in several biological processes of the cardiovascular system, including VSMC proliferation, migration, and death. However, it is unknown if the miR-4284 gene is involved in the control of ASO. Furthermore, the molecular processes behind the contribution of human arterial smooth muscle cells (HASMCs), one of the most significant components of the arterial wall, to arteriosclerosis obliterans (ASO) pathogenesis remain unknown...

INTRODUCTION: Patients with peripheral arterial disease (PAD) have a poorer prognosis than those without PAD. PAD complications worsen the prognosis of patients with chronic kidney disease (CKD), especially those on maintenance dialysis. Although low-density lipoprotein apheresis (LDL-A) is expected to be effective in treating severe PAD, there are no large-scale reports on the prognosis of patients undergoing LDL-A. METHODS: We obtained a clinical database from April 2008 to August 2021 and selected 924 238 patients with CKD...
