Increased expression of K<sub>Ca</sub>3.1 has been found in Vascular Smooth Muscle (VSM), macrophages and T-cells in lesions from humans and mice. Increased expression of K<sub>Ca</sub>3.1, is also required for VSM cell proliferation and migration. Previously, we showed that the specific K<sub>Ca</sub>3.1 inhibitor, TRAM-34, could inhibit coronary neointimal development following balloon injury in swine. Atherosclerosis develops in regions with a low, oscillatory (i.e. atheroprone) flow pattern. Therefore, we used the Partial Carotid Ligation (PCL) model in high-fat fed, Apoe<sup>-/-</sup> mice to determine the role of K<sub>Ca</sub>3.1 in atherosclerotic lesion composition and development. PCL was performed on 8-10 week old male Apoe<sup>-/-</sup> mice and subsequently placed on a Western diet (TD.88137, Teklad) for 4 weeks. Mice received daily s.c. injections of TRAM-34 (120 mg/kg) or equal volumes of vehicle (peanut oil, PO). 1-[(2-chlorophenyl) diphenylmethyl]-1H-pyrazole (TRAM-34) treatment reduced lesion size ~50% (<i>p</i> < 0.05). In addition, lesions from TRAM-34 treated mice contained less collagen (6% ± 1% vs. 15% ± 2%; <i>p</i> < 0.05), fibronectin (14% ± 3% vs. 32% ± 3%; <i>p</i> < 0.05) and smooth muscle content (19% ± 2% vs. 29% ± 3%; <i>p</i> < 0.05). Conversely, TRAM-34 had no effect on total cholesterol (1455 vs. 1334 mg/dl, PO and TRAM, resp.) or body weight (29.1 vs. 28.8 g, PO and TRAM, resp.). Medial smooth muscle of atherosclerotic carotids showed diminished RE1-Silencing Transcription Factor (REST)/Neural Restrictive Silencing Factor (NRSF) expression, while REST overexpression <i>in vitro</i> inhibited smooth muscle migration. Together, these data support a downregulation of REST/NRSF and upregulation of K<sub>Ca</sub>3.1 in determining smooth muscle and matrix content of atherosclerotic lesions.</p>","PeriodicalId":8466,"journal":{"name":"Artery Research","volume":"27 2","pages":"93-100"},"PeriodicalIF":0.6,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/ae/08/nihms-1718074.PMC8388312.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39364491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been well recognized that arterial stiffness and wave reflection measured by the aortic pulse wave velocity and Augmentation Index (AIx) are the strong predictors of future Cardiovascular events and all-cause mortality [1,2]. However, these measures require technical expertise and knowledge. In this context, the Second Derivative waveform of fingertip Photoplethysmography (SDPTG) can be measured easily from a fingertip placed on the photoplethysmography (PTG) sensor and has the potential for selfmonitoring of vascular health during daily living [3]. Previously, several studies have demonstrated clinical and pathophysiological importance of SDPTG indices such as the SDPTG Aging Index (SDPTGAI) [4–6]. Since SDPTGAI is strongly correlated with age, it can be rescaled to years of age which is easily comprehended by general populations [3]. For these reasons, SDPTG indices including the vascular aging index have recently been implemented for ambulatory monitoring devices, but its usability and reliability are not well documented. Mental stress is an external stimulus that can affect physiological parameters such as arterial tone [5,7], blood viscosity [8], and heart rate [9]. It is reported that pulse wave velocity and AIx are increased with acute mental stress [10,11]. Moreover, skin blood flow shows transient reflex changes in response to various external stimuli (e.g., arousing or painful stimuli, emotional stress) [12]. Since photoplethysmogram optically evaluates blood volume changes in the microvascular bed of cutaneous tissue, SDPTG may be influenced by mental stressor independent of changes in vascular tone and stiffness of the relatively proximal vessels.","PeriodicalId":8466,"journal":{"name":"Artery Research","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69872192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to compare the effects of interventional and conservative therapies on lower extremity ASO, and to analyze the risk factors for prognosis. Methods: Ninety-eight eligible patients were randomly divided into experimental ( n = 50) and control groups ( n = 48). Conservative therapy was conducted for control group, and experimental group was given conservative and interventional therapies. Their baseline clinical data, hospital stay length, claudication distance, Rutherford stage, diseased arteries, Ankle-Brachial Index (ABI), clinical outcomes and adverse events were recorded. Then they were divided into poor ( n = 31) and good prognosis groups ( n = 67), and risk factors were explored by univariate and multivariate analyses. Results: The hospital stay length of experimental group was significantly shorter than that of control group ( p < 0.05). After treatment, Rutherford stage decreased, and vascular patency rate and total response rate rose in experimental group ( p < 0.05). Claudication distance and ABI significantly increased in both groups compared with those before treatment, especially in experimental group ( p < 0.05). The incidence rates of cardiovascular and cerebrovascular events, amputation and death were significantly lower in experimental group ( p < 0.05). Age, conservative therapy, smoking, hypertension, diabetes mellitus, hyperlipidemia and fibrinogen were independent risk factors for poor prognosis ( p < 0.05). Age of >70 years old and fibrinogen level of >4 g/L had greater effects on prognosis.
