Di-2-pyridylketone-4,4-dimethyl-3-thiosemicarbazone (Dp44mT), the novel iron chelator, has been reported to inhibit the tumorigenesis and progression of various cancer cells, including neuroblastoma, neuroepithelioma and prostate cancer. However, whether Dp44mT has anticancer effects in osteosarcoma is still unknown. Here, we investigated the antitumor(More)
Non-healing diabetic wounds are difficult to treat. They also create heavy financial burdens for both patients and society. Negative pressure wound therapy (NPWT) has been adopted to treat intractable wounds and has proved to be effective. However, the mechanisms that underlie the effects of this treatment are not entirely understood. Circulating fibrocytes(More)
Acute lower extremity ischemia is a limb-and life-threatening problem. The timing of clinical intervention is critical to achieving optimal outcomes. However, there has been a lack of effective techniques capable of evaluating muscle and limb damage. Microcirculatory injury is the initial pathological change during ischemic muscle injury. Here, we performed(More)
Background: Although there is plentiful evidence favoring the fixation of the skin flaps to the underlying muscles (quilting) to prevent seroma formation after axillary lymph node dissection (ALND), there is a paucity of study concerning its treatment effect. Several randomized controlled trials (RCTs) demonstrated quilting group did not require(More)
Congenital heart disease (CHD) is the most frequent birth defect. RCAN1 (regulator of calcineurin 1) contributes to CHD in Down syndrome. However, whether RCAN1 is also associated with nonsyndromic CHD remains unclear. This study sequenced the exons and flanking region of RCAN1 in 128 sporadic CHD patients and 150 normal controls. We identified six novel(More)
Poor viability of engrafted bone marrow mesenchymal stem cells (BMSCs) often hinders their application for wound healing, and the strategy of how to take full advantage of their angiogenic capacity within wounds still remains unclear. Negative pressure wound therapy (NPWT) has been demonstrated to be effective for enhancing wound healing, especially for the(More)
Negative pressure wound therapy (NPWT) has been revealed to be effective in the treatment of open fractures, although the underlying mechanism is not clear. This article aimed to investigate the effects of NPWT on muscle-derived stem cell (MDSC) osteoblastic differentiation and the related potential mechanism. The cell proliferation rate was substantially(More)
Recently, hypoxia inducible factor-1 (HIF-1) was reported to be correlated with isocitrate dehydrogenase 1 (IDH-1) in several types of tumors. However, the expression and significance of HIF-1 and IDH-1 in osteosarcoma is still unknown. In the present study, the expression levels of IDH-1 and HIF-1α in 35 formalin-fixed paraffin-embedded sections from(More)
BACKGROUND It is controversial whether surgical zipper technique (SZT), a non-invasive method of surgical wound closure, achieves a better outcome of incision healing than intracutaneous sutures (IS) in the surgery. This meta-analysis was performed to systematically analyze whether surgical zipper is superior to suture material for the incision closure. (More)
BACKGROUND Perforator flap techniques with conventional wound dressing have being extensively used in the management of soft-tissue defects. However; the flap's survival rate is not always guaranteed and the wound healing time always long. The aim of this study was to investigate the clinical effectiveness use of a freshly transplanted perforator flap in(More)
