899 from the right or left anterior descending cor‐ onary artery; therefore, Cx fistulas are unique. A great majority of fistulas bypass the blood from the arterial to venous systems, such as the pulmo‐ nary artery, coronary sinus, superior vena cava, or right ‐sided heart chambers. Most patients re‐ main asymptomatic.1 Possible clinical presenta‐ tions of coronary fistulas include angina, myocar‐ dial infarction, heart failure symptoms, endocar‐ ditis, arrhythmias, and they are related with the size and location of a fistula.3 Of note, most pa‐ tients develop symptoms of myocardial ischemia in their fourth to sixth decade of life.4 Myocardi‐ al ischemia associated with coronary fistulas can be secondary or, less common, primary.4 Coronary steal syndrome was a possible expla‐ nation of angina in our patient. Potential compli‐ cations of coronary fistulas are aneurysmal remod‐ eling of drained artery, which was present in our patient, and rupture or thrombosis of the fistula. Coronary angiography is the gold standard for di‐ agnosing coronary fistula.1 Nevertheless, nonin‐ vasive methods such as color ‐flow Doppler ultra‐ sound, magnetic resonance imaging, and comput‐ ed tomography can be useful in diagnosis, as they show the exact shape and anatomy of arteriove‐ nous connections of fistulas.5 Treatment is recom‐ mended only for symptomatic patients, and pos‐ sible options are surgical or transcatheter fistula closure. Surgical treatment was the most common technique until the introduction of transcatheter techniques in carefully selected patients with suit‐ able anatomy of the fistula, namely, accessible with a closure device and with no other indications for surgery.1 Coronary artery fistulas, although rare, should be considered in a differential diagnosis of chest pain, particularly in young patients without known risk factors of atherosclerosis. A 61 ‐year ‐old Caucasian woman with a history of ischemic heart disease, hypertension, type 2 dia‐ betes, and hypercholesterolemia was admitted to the hospital due to unstable angina. Three months prior to hospitalization, an exercise treadmill test was performed showing a significant down sloping ST ‐segment depression of 1.5 mm in leads III, aVF, and V4–V6, at 7 metabolic equivalents of exercise with no chest pain. A physical examination was unremarkable, blood pressure was 130/75 mmHg, and the pulse rate was regular (66 bpm). An elec‐ trocardiogram on admission revealed inferolat‐ eral ST ‐segment depression with ST ‐segment el‐ evation in lead aVR, suggesting diffuse subendo‐ cardial ischemia. Routine blood test results were normal. The measurement of high ‐sensitivity car‐ diac troponin levels yielded negative results. Ur‐ gent transthoracic echocardiography showed no wall motion abnormalities with normal left ven‐ tricular ejection fraction of 65%. On a comput‐ ed tomography (CT) angiography, a fistula from the circumflex artery (Cx) to coronary sinus was suspected (FIGURE 1A–C). The coronary an
899从右或左冠状动脉前降支;因此,Cx瘘管是独特的。绝大多数瘘管将血液从动脉分流到静脉系统,如肺动脉、冠状窦、上腔静脉或右侧心腔。大多数患者仍无症状冠状动脉瘘管可能的临床表现包括心绞痛、心肌梗死、心力衰竭症状、腔内炎、心律失常,它们与瘘管的大小和位置有关值得注意的是,大多数pa -患者在他们生命的第四个到第六个十年出现心肌缺血症状与冠状动脉瘘相关的心肌缺血可以是继发性的,也可以是不太常见的原发性的冠状动脉偷取综合征是本例患者心绞痛的一个可能的解释。冠状动脉瘘管的潜在并发症是引流动脉的动脉瘤切除,如本例患者,以及瘘管破裂或血栓形成。冠状动脉造影是诊断冠状动脉瘘的金标准然而,无创方法如彩色多普勒超声、磁共振成像和计算机断层扫描在诊断中是有用的,因为它们显示了瘘的动神经连接的确切形状和解剖结构建议仅对有症状的患者进行治疗,可能的选择是手术或经导管瘘管闭合。手术治疗是最常见的技术,直到经过精心挑选的具有适合的瘘管解剖结构的患者引入经导管技术,即可以使用闭合装置并且没有其他手术指征冠状动脉瘘管虽然罕见,但在胸痛的鉴别诊断中应予以考虑,特别是在没有已知动脉粥样硬化危险因素的年轻患者中。一位61岁的白人女性,有缺血性心脏病、高血压、2型糖尿病和高胆固醇血症病史,因不稳定型心绞痛入院。住院前3个月,进行运动跑步机试验,在7次代谢当量的运动中,III、aVF和V4-V6导联ST段明显下移1.5 mm,无胸痛。体格检查无异常,血压130/75 mmHg,脉搏正常(66 bpm)。入院时的心电图显示,aVR导联ST段降低伴ST段升高,提示弥漫性心内膜下缺血。血常规检查正常。高灵敏度car - diac肌钙蛋白水平的测量结果为阴性。经胸超声心动图显示无壁运动异常,左心室射血分数正常,为65%。在计算机断层扫描(CT)血管造影中,怀疑从旋动脉(Cx)到冠状窦有瘘(图1A-C)。冠状动脉造影证实在动脉瘤性Cx和冠状窦之间有一个大瘘管,无冠状动脉狭窄(图1D)。在心脏科会诊后,患者被推荐进行外科瘘管闭合手术,并成功进行了手术。手术一年后,CT血管造影排除了Cx和冠状窦之间的任何通信。经过6年的随访,患者总体情况良好,无心绞痛症状。冠状动脉动静脉瘘是一种罕见的异常,每千例冠状动脉造影中有3 - 8例可见。此外,由瘘管引流的动脉形成动脉瘤是罕见的通常,瘘管出现在临床影像中

INTRODUCTION Advanced glycation end products (AGEs) play a crucial role in the pathogenesis of diabetic peripheral neuropathy (DPN). OBJECTIVES The aim of the study was to assess the skin accumulation of AGEs in patients with long‑lasting type 1 diabetes in relation to the presence of DPN. PATIENTS AND METHODS We evaluated 178 patients with type 1 diabetes (99 men; age, 43 years [interquartile range [IQR], 34-54 years]; disease duration, 25 years [IQR, 18-31 years]). DPN was diagnosed if 2 or more of the following 5 abnormalities were present: symptoms of neuropathy, lack of ankle reflexes, and impaired sensation of touch, temperature, and/or vibration. PGP 9.5‑immunoreactive nerve fibers were counted to assess intraepidermal nerve fiber density (IENFD) in skin biopsy. The accumulation of AGEs in the skin was assessed on the basis of skin autofluorescence (AF).  RESULTS Patients with DPN (45%), compared with those without neuropathy, had higher skin AF (2.6 AU [IQR, 2.3-3.1 AU] vs 2.1 AU [IQR, 1.8-2.5 AU]; P <0.001) and lower IENFD (10 fibers/mm [IQR, 7-14 fibers/mm] vs 12 fibers/mm [IQR, 8-16 fibers/mm]; P = 0.005). We found a positive correlation between skin AF and patients' age (Rs = 0.44; P <0.001), diabetes duration (Rs = 0.32; P <0.001), and a negative correlation between skin AF and the estimated glomerular filtration rate (Rs = -0.26, P <0.001) and IENFD (Rs = -0.22; P = 0.004). In a multiple linear regression analysis, skin AF was independently associated with age (β = 0.45; P <0.001), glycated hemoglobin level (β = 0.19; P = 0.007), and IENFD (β = - 0.14; P = 0.04) (R2 = 0.27; P <0.001). In multivariate logistic regression, the presence of DPN was independently associated with skin AF (odds ratio, 4.16; 95% confidence interval, 1.88-9.20; P <0.001). CONCLUSIONS The presence of DPN, and particularly small fiber neuropathy, is associated with a higher accumulation of AGEs in the skin of patients with type 1 diabetes.
晚期糖基化终产物(AGEs)在糖尿病周围神经病变(DPN)的发病机制中起着至关重要的作用。该研究的目的是评估长期1型糖尿病患者皮肤中AGEs积累与DPN存在的关系。患者和方法我们评估了178例1型糖尿病患者(99例男性;年龄,43岁[四分位数间距[IQR], 34-54岁];病程25年[IQR, 18-31年])。如果出现以下5种异常中的2种或2种以上,则诊断为DPN:神经病变症状、踝关节反射缺乏、触觉、温度和/或振动感觉受损。计数PGP 9.5免疫反应性神经纤维,以评估皮肤活检中表皮内神经纤维密度(IENFD)。根据皮肤自身荧光(AF)测定AGEs在皮肤中的积累情况。结果:与无神经病变的患者相比,DPN患者(45%)的皮肤AF更高(2.6 AU [IQR, 2.3-3.1 AU] vs 2.1 AU [IQR, 1.8-2.5 AU];P <0.001)和较低的IENFD(10根纤维/mm [IQR, 7-14根纤维/mm] vs 12根纤维/mm [IQR, 8-16根纤维/mm];P = 0.005)。我们发现皮肤房颤与患者年龄呈正相关(Rs = 0.44;P <0.001)、糖尿病病程(Rs = 0.32;P <0.001),皮肤AF与肾小球滤过率(Rs = -0.26, P <0.001)和IENFD (Rs = -0.22;P = 0.004)。在多元线性回归分析中,皮肤AF与年龄独立相关(β = 0.45;P <0.001),糖化血红蛋白水平(β = 0.19;P = 0.007), IENFD (β = - 0.14;P = 0.04) (r2 = 0.27;P < 0.001)。在多因素logistic回归中,DPN的存在与皮肤AF独立相关(优势比4.16;95%置信区间为1.88-9.20;P < 0.001)。结论:DPN的存在,特别是小纤维神经病变,与1型糖尿病患者皮肤中AGEs的较高积累有关。

Humans, like other species that reproduce sexually, originate from a fertilized oocyte (zygote), which is a totipotent stem cell giving rise to an adult organism. During the process of embryogenesis, stem cells at different levels of the developmental hierarchy establish all 3 germ layers and give rise to tissue‑committed stem cells, which are responsible for rejuvenation of a given tissue or organ. The robustness of the stem cell compartment is one of the major factors that directly impact life quality as well as lifespan. Stem cells continuously replace cells and tissues that are used up during life; however, this replacement occurs at a different pace in various organs. The rapidly developing field of regenerative medicine is taking advantage of these physiological properties of stem cells and is attempting to employ them in clinical settings to regenerate damaged organs (eg, the heart, liver or bone). For this purpose, the stem cells most successfully employed so far are adult tissue-derived stem cells isolated mainly from bone marrow, mobilized peripheral blood, umbilical cord blood, fat tissue, and even myocardial biopsies. At the same time, attempts to employ embryonic stem cells and induced pluripotent stem cells in the clinic have failed due to their genomic instability and the risk of tumor formation. In this review, we will discuss the various potential sources of stem cells that are currently employed in regenerative medicine and the mechanisms that explain their beneficial effects. We will also highlight the preliminary results of clinical trials as well as the emerging problems relating to stem cell therapies in cardiology.
人类,像其他有性繁殖的物种一样,起源于受精的卵母细胞(受精卵),这是一种能产生成年生物体的全能干细胞。在胚胎发生过程中,处于不同发育层次的干细胞建立了所有3个生殖层,并产生组织承诺干细胞,这些干细胞负责给定组织或器官的再生。干细胞室的稳健性是直接影响生命质量和寿命的主要因素之一。干细胞不断地替代生命中耗尽的细胞和组织;然而,这种替换在不同的器官中以不同的速度发生。快速发展的再生医学领域正在利用干细胞的这些生理特性,并试图在临床环境中应用它们来再生受损的器官(如心脏、肝脏或骨骼)。为此目的,迄今为止最成功使用的干细胞是主要从骨髓、动员的外周血、脐带血、脂肪组织甚至心肌活检中分离的成体组织来源的干细胞。与此同时,由于胚胎干细胞和诱导多能干细胞基因组的不稳定性和肿瘤形成的风险,在临床应用的尝试失败了。在这篇综述中,我们将讨论目前用于再生医学的各种潜在干细胞来源以及解释其有益作用的机制。我们还将重点介绍临床试验的初步结果以及与心脏病学干细胞治疗相关的新问题。

803 of coronary narrowing. These people were randomized to either placebo or a drug called empagliflozin, and they were actually randomized to 2 different doses of empagliflozin, either 10 mg or 25 mg. The primary analysis was to compare the placebo group to the combined both-doses group. The study continued for 3.1 years, patients were seen periodically, and as I said, it was a blinded study, so investigators were told to manage the patients’ blood pressure, lipids, and glucose levels to the best of their abilities, obviously unaware of the drug the people were taking. At the end of a median follow -up of 3.1 years, the study ended and the results were presented at the European diabetes meeting in September. They showed that people randomized to empagliflozin had a 14%—very significant—reduction in the composite outcome of nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes. Even more interesting and more striking was that there was a totally independent reduction in death from all causes as well as death from cardiovascular causes, and a 30% to 35% reduction additionally in death from heart failure with no major effect on myocardial infarction or stroke alone. This study is very unique in that it really showed a very clear benefit of this glucose-lowering drug on serious health outcomes.
803冠状动脉狭窄。这些人被随机分到安慰剂组和恩帕列净组,他们被随机分到两种不同剂量的恩帕列净组,分别是10毫克和25毫克。主要的分析是比较安慰剂组和双剂量联合组。这项研究持续了3.1年,患者定期接受检查,正如我所说,这是一项盲法研究,因此调查人员被告知要尽其所能控制患者的血压、血脂和血糖水平,显然不知道患者服用的是什么药物。中位随访期为3.1年,研究结束,研究结果在9月的欧洲糖尿病会议上公布。他们发现,随机接受恩格列净治疗的患者在非致死性心肌梗死、非致死性中风或心血管原因死亡的综合结果中降低了14%,这是非常显著的。更有趣,更惊人的是,所有原因导致的死亡和心血管原因导致的死亡都有完全独立的减少,心力衰竭导致的死亡也有30%到35%的额外减少,而心肌梗死或中风没有主要影响。这项研究非常独特,因为它确实显示了这种降血糖药物对严重健康结果的非常明确的益处。

814 in this way it was easier to upkeep the internal medicine units. It is high time that we protested firmly against the depreciation of the significance of internal dis­ eases in clinical practice. The reasons for this are many, for example they stem from the fact that only the internal medicine specialists can provide a holistic approach to the patient, while at the same time acting as doctors who solve numerous and very difficult clinical problems, working both in their own units as well as in surgical, neurol­ ogy, infectious diseases, dermatology units, etc. It is known that the internal medicine special­ ists function successfully for example in the Unit­ ed States. It has become apparent that experi­ enced internists are a “treasure” for the hospi­ tal because they are able to analyze the majori­ ty of additional tests, be it endoscopic, imaging, or laboratory examination. Then, taking into ac­ count a clinical picture of a disease, they are able to synthesize all information based on which they tie all loose ends, thus providing a correct diag­ nosis.

这样保养内科病房就容易多了。现在是我们坚决反对贬低内科疾病在临床实践中的重要性的时候了。造成这种情况的原因有很多,例如,它们源于这样一个事实,即只有内科专家才能为病人提供全面的方法,同时作为医生解决许多非常困难的临床问题,既在自己的单位工作,也在外科、神经病学、传染病、皮肤病学等单位工作。众所周知,内科专科医生的工作很成功,例如在美国。经验丰富的内科医生显然是医院的“财富”,因为他们能够分析大多数附加检查,无论是内窥镜检查、影像学检查还是实验室检查。然后,考虑到一种疾病的临床图像,他们能够综合所有的信息,根据这些信息,他们解决了所有的问题,从而提供了一个正确的诊断。人们不应忘记,基于准确行动和随后适当治疗建议的准确诊断可转化为切实的经济成果。在一个越来越复杂的医学领域采取这种行动,需要对疾病进行详细的鉴别诊断,这不仅涉及到内科单位的工作,而且涉及到内科医生必不可少的不同单位的会诊,这也证明了他们被“剥削”的原因。如果我们不恢复内科及其专家应有的重要性,那么我们可以预见,在不久的将来,我们将看到医生在诊断和治疗方面犯下越来越多的错误。总的来说,我们在诊断和治疗方面可能会面临一定的混乱。我们需要记住,在医学和病人治疗中2×2并不总是4。经常,在诊断过程中,也在十多年来,我们一直在观察内科疾病和内科专家的持续贬值,尽管对他们的服务有巨大的需求,这可以从医院和门诊诊所目前的活动中看出。这反映在内科诊所的关闭和内科单位的名称中补充了额外的术语,这些术语与内科医学产生的详细特殊专业有关,自内科医学论坛以来
