BACKGROUND AND AIMS: Vascular smooth muscle cell (VSMC) dedifferentiation contributes to neointima formation, which results in various vascular disorders. Intermedin (IMD), a cardiovascular paracrine/autocrine polypeptide, is involved in maintaining circulatory homeostasis. However, whether IMD protects against neointima formation remains largely unknown. The purpose of this study is to investigate the role of IMD in neointima formation and the possible mechanism. METHODS: IMD1-53 (100ng/kg/h) or saline water was used on rat carotid-artery balloon-injury model...

Massive hemorrhage causes instant and early deaths because of hypovolemia. However, even if the victim makes it to the hospital, hypothermia, metabolic acidosis, and coagulation impairments caused by bleeding pose a great risk for survival. Many topical hemostatic agents are developed for neck, armpit, or groin injuries that are not amenable to tourniquet application and for extremity wounds to be used in conjunction with tourniquets. This paper focuses on those hemostatics that differ based on the action mechanism and are suitable for pre-hospital setting and summarizes the latest recommendations regarding their usage...

The formation of external carotid artery (ECA) pseudoaneurysms caused by stab wounds is a rare vascular anomaly. Although the surgical exploration of the ECA segment is the standard treatment, endovascular treatment (EVT) can be considered if there is difficulty in identifying the source of bleeding in the injured regions that are difficult to operatively access. Here we treated a young patient who had hemorrhagic instability with hemorrhage-induced coagulopathy caused by a zone III cervical stab wound with a pseudoaneurysm from the main trunk of the ECA; the patient underwent EVT and successful hemostasis...

INTRODUCTION: Rupture of the Achilles' tendon is a common injury occurring particularly in middle-aged men due to sports trauma. Operative treatment is preferred generally due to lower risk of re-rupture. Possible complications of the operation include suture granulomas. Suture granulomas might represent a foreign body reaction, which itself is the end-stage response of the inflammatory wound-healing process to biomaterials. It may occur with both absorbable and non-absorbable suture materials such as silk in our case...

Damage control for thoracic trauma combines definitive and temporary surgical gestures specifically adapted to the lesions present. A systematic assessment of all injuries to prioritize the specific lesions and their treatments constitutes the first operative stage. Packing and temporary closure have a place in the care of chest injuries.

Angiogenesis is a process of new blood vessel formation from pre-existing vessels. It is a normal and vital process in growth and development, as well as in wound healing and in the formation of granulation tissue. Total flavones of Abelmoschus manihot (TFA) are the major constituents of the traditional Chinese herb Abelmoschus manihot L. Medic. The aim of this study is to investigate the effect of TFA on angiogenic ability using human umbilical vein endothelial cells (HUVECs) in vitro and chick chorioallantoic membrane (CAM) in vivo...

After traumatic injury, some cells function as detectors to sense injury and to modulate the local immune response toward a restitution phase by affecting the local cytokine milieu. Using intravital microscopy, we observed that patrolling invariant natural killer T (iNKT) cells were initially excluded from a site of hepatic injury but subsequently were strategically arrested first via self-antigens and then by cytokines, circumscribing the injured site at exactly the location where monocytes co-localized and hepatocytes proliferated...

We investigated the biological effects of Er:YAG laser (2,940-nm; DELight(®) , HOYA ConBio, USA) irradiation at fluences of 3.6, 4.2, 4.9, 6.3, 8.1, or 9.7 J cm(-2) at 20 or 30 Hz for 20 or 30 s on primary human gingival fibroblasts (HGFs). Irradiation at 6.3 J cm(-2) promoted maximal cell proliferation, determined by WST-8 assay and crystal violet staining, but was accompanied by lactate dehydrogenase release, on day 3 post-irradiation. Elevation of ATP level, Ki67 staining, and cyclin-A2 mRNA expression confirmed that Er:YAG affected the cell cycle and increased the number of proliferating cells...

Arteriovenous malformations (AVMs) are rare congenital vascular malformations accounting only 1.5% of all vascular anomalies with 50% occurrence in the oral and maxillofacial region. It usually results from birth defects of the vasculature. A literature search revealed only few case reports of AVMs in the facial region. Lack of meticulous diagnosis, scarcity of knowledge, and paucity of literature can result in their exsanguinations leading to fatal hemorrhagic incidents after various dental procedures such as tooth extraction, surgical intervention, puncture wound, or blunt injury in involved area...

Leukotriene B4 (LTB4), a lipid mediator produced from arachidonic acid, is a chemoattractant for inflammatory leukocytes. We identified two receptors for LTB4, the high-affinity receptor BLT1 and the low-affinity receptor BLT2. BLT1 is expressed in various subsets of leukocytes, and analyses of BLT1-deficient mice revealed that the LTB4/BLT1 axis enhances leukocyte recruitment to infected sites, and is involved in the elimination of pathogens. Hyperactivation of the LTB4/BLT1 axis induces acute and chronic inflammation, resulting in various inflammatory diseases...

BACKGROUND: Most combat casualties who die, do so in the prehospital setting. Efforts directed toward alleviating prehospital combat trauma death, known as killed in action (KIA) mortality, have the greatest opportunity for eliminating preventable death. METHODS: 4,542 military casualties injured in Afghanistan from September 11, 2001 to March 31, 2014 were included in this retrospective analysis to evaluate proposed explanations for observed KIA reduction following a mandate by Secretary of Defense Robert M...

The most favorable treatment for acute Achilles tendon ruptures remains controversial. In particular, three key questions are intensively debated: is operative or non-operative treatment superior? If surgery is performed, should open or minimally invasive percutaneous techniques be used? How should the follow-up treatment be carried out? The aim of this article is to answer these essential questions based on the currently available evidence. Non-operative treatment leads to a higher rate of re-ruptures and inferior functional results when compared to operative treatment...

Hyperglycemia (HG) induces genome-wide cytosine demethylation. Our previous work recognized miR-200b as a critical angiomiR, which must be transiently downregulated to initiate wound angiogenesis. Under HG, miR-200b downregulation is not responsive to injury. Here, we demonstrate that HG may drive vasculopathy by epigenetic modification of a miR promoter. In human microvascular endothelial cells (HMECs), HG also lowered DNA methyltransferases (DNMT-1 and DNMT-3A) and compromised endothelial function as manifested by diminished endothelial nitric oxide (eNOS), lowered LDL uptake, impaired Matrigel tube formation, lower NO production, and compromised VE-cadherin expression...
