摘要： A referral patient who had previously undergone varicose vein surgery was admitted as an emergency case. On admission, the patient complained of intolerable pain, paralysis and paresthesia of the affected limb, which was characterized by acute arterial ischemia symptoms. Color Doppler of the artery of the affected limb indicated that no blood flow signal existed in the superficial femoral artery. During exploratory operation, we found that the right superficial femoral artery instead of the great saphenous vein of the affected limb had been stripped and ligated. Therefore, the intact right great saphenous vein was taken for auto-transplantation by inverse end-to-end anastomosis to the proximal and distal residual superficial femoral artery, which resulted in gradual recovery. Except for ischemic reperfusion injury, no other post-operative complications occurred after a 10 month follow-up; however, the long-term curative effect needs further observation. Here we report our treatment experience.

摘要： The aim of this paper was to investigate the effects of resistin on human umbilical vein endothelial cells (HUVECs), and to explore its role and mechanism of action in atherosclerosis. HUVECs were incubated with recombinant human resistin (0, 50, 100 ng/mL) for 24 h. ICAM-1, VCAM-1 and reactive oxygen species (ROS) were assayed by flow cytometer. ET-1, eNOS and iNOS mRNA expression were measured by semi-quantitative RT-PCR. Incubation of HUVECs with resistin resulted in an increase in ICAM-1 expression and ET-1 mRNA expression. However, resistin had no effect on VCAM-1 expression and ROS release. eNOS and iNOS mRNA expression were not altered by resistin stimulation. Adipokine resistin exerted a direct effect in promoting HUVEC dysfunction by promoting ICAM-1 and ET-1 expression. These data suggest that adipocyteendothelium cross-talk might play an important role in the pathogenesis of cardiovascular disease in diabetes mellitus.

摘要： Vein of Galen malformations (VGMs) are rare, consisting approximately 1% of intracranial vascular malformations, but nearly one third of pediatric vascular malformations, which can cause severe morbidity and mortality in infants and older children, but more particularly in neonates. We presented 2 patients with VGMs which were confirmed by characteristic clinical symptoms and neuroradiological findings (including CT, MRI and/or angiography). One patient underwent embolization followed by CT, MRI and conventional angiography. The patient’s neurological and cognitive status was normal at present. The other neonate died of congestive heart failure 36 h after birth.

The second short-term warm ischemia after vascular anastomosis did not affect early renal function recovery in renal transplantation: a case report

null

摘要：

Ischemic postconditioning was defined as rapid intermittent interruptions of blood ?ow in the early phase of reperfusion, which has been found to be protective against renal ischemia-reperfusion injury (IRI) in animal models but not in clinical trials. We describe a case that the allograft renal vein was twisted because of the surgeon’s mistake, which caused the warm ischemia of allograft after reperfusion. The allograft restored blood flow without second reperfusion and cold preservation after 9 min of warm ischemia. The patient was followed up for 3 months and the allograft worked well without complications.
