In vivo MRI tracking of iron oxide nanoparticle-labeled human mesenchymal stem cells in limb ischemia.

Background: Stem cell transplantation has been investigated for repairing damaged tissues in various injury models. Monitoring the safety and fate of transplanted cells using noninvasive methods is important to advance this technique into clinical applications.

Methods: In this study, lower-limb ischemia models were generated in nude mice by femoral artery ligation.

Long-term MRI tracking of dual-labeled adipose-derived stem cells homing into mouse carotid artery injury.

Background: Stem cell therapy has shown great promise for regenerative repair of injured or diseased tissues. Adipose-derived stem cells (ADSCs) have become increasingly attractive candidates for cellular therapy. Magnetic resonance imaging has been proven to be effective in tracking magnetic-labeled cells and evaluating their clinical relevance after cell transplantation.

[Subintimal angioplasty for chronic arterial occlusive disease: a systematic review].

Objective: To evaluate the clinical effectiveness of subintimal angioplasty in treating chronic arterial occlusive disease of lower extremity.

Methods: Eligible studies concerning treatment by subintimal angioplasty in patients with arterial occlusive disease of lower extremity were identified from electronic database, cross-reference search and relative articles. The study quality and data extraction of all relevant articles were assessed by three independent reviewers.

[Endovascular angioplasty for the treatment of long iliac artery chronic total occlusions].

Objective: To evaluate the effectiveness, safety and feasibility of endovascular angioplasty in treating long iliac artery chronic total occlusions (CTO).

Methods: The clinical data from a consecutive series of patients with long (> 5 cm) iliac artery CTO who treated by endovascular angioplasty from January 2006 to December 2010 was retrospectively analyzed. There were 139 patients (157 limbs) with long iliac artery CTO treated by endovascular angioplasty in this study [male 93 and female 46, mean age (77 ± 10) years].

[Effect of transarterial embolization on persistent type II endoleaks after endovascular aneurysm repair: a meta-analysis].

Objective: To evaluate the clinical effectiveness of transarterial embolization in persistent type II endoleak after endovascular aneurysm repair (EVAR).

Methods: Eligible studies concerning treatment by transarterial embolization in patients with persistent type II endoleak after EVAR were identified from electronic database, cross-reference search and pertinent articles. All relevant studies were systematically reviewed and the data were extracted by two independent reviewers.
