“Pulsed acoustic cellular expression (PACE) is a treatment that applies focused acoustic shock waves to promote tissue healing. The aim of this study was to assess the effect of PACE treatment on inflammatory responses in a cremaster muscle ischemia/reperfusion injury model. Seventeen cremaster muscle flaps were evaluated

in four groups: nonischemic controls (n = 5), 5-hour https://www.selleckchem.com/products/Aloxistatin.html ischemia controls (n = 4), preischemic (5-hour) PACE conditioning (n = 4), and postischemic (5-hour) PACE conditioning (n = 4). The expression of proinflammatory cytokines (TNFα, IL-6, IL-1α, IL-1β, GM-CSF) and chemokines (CCL3, CCL4, CXCL4) was assessed using TaqMan® real-time PCR. Expression of ELAM-1, VCAM-1, and ICAM-1 was assessed by immunostaining. Preischemic PACE conditioning upregulated expression of IL-6, CCL3, CCL4, and CXCL4, and downregulated expression of TNFα, GM-CSF, and IL-1α. Postischemic PACE conditioning significantly decreased expression of all evaluated genes. Pre- and postischemic PACE conditioning decreased expression of ELAM-1 and ICAM-1. Results of the study indicate

that application MLN0128 of PACE conditioning may have a beneficial effect on the recovery of tissues subjected to the ischemia/reperfusion injury. Postischemic PACE conditioning revealed anti-inflammatory effect as confirmed by decreased expression of inflammatory cytokines, chemokines, and cell adhesion molecules (ELAM-1 and Farnesyltransferase ICAM-1) that are responsible for leukocyte

recruitment into ischemic tissues. Hence, PACE therapy may be used effectively in clinical practice as a convenient therapeutic strategy to protect tissues against ischemia/reperfusion related injury after microsurgical procedures of free tissue transfers. © 2012 Wiley Periodicals, Inc.

“The reconstruction of complex hand injury such as multifinger soft tissue defect remains a challenging problem. Two cases of repair of multifinger injury with exposed bones using the free chimeric flaps based on the dorsalis pedis vessels are presented. Two male patients, 46 years old and 36 years old, suffered from a thermocompression injury to the dorsum of fingers resulting in soft tissue defects of multiple fingers. The chimeric free flap was designed and applied to cover the defects. The donor sites were covered by skin grafts. The postoperative courses were uneventful. Both patients were followed up for 10–12 months. The maximal flexion angle of the distal interphalangeal, proximal interphalangeal, and metacarpophalangeal joints were 40°–85° at the end of the follow-up. The protective sensation was achieved on the dorsal fingers. The report suggests that the free chimeric flaps based on the dorsalis pedis artery may be an alternative for the reconstruction of the multifinger dorsal soft tissue defects. © 2013 Wiley Periodicals, Inc.
