Guoming Sun
The transformation of fibrotic healing process to regenerative one has great potential to fully restore wounded skin. The M2 macrophage phenotype promotes constructive tissue remodeling and instructs tissue repair in a regenerative manner. It is hypothesized that hydrogels that can establish robustness of endogenous cells to regulate M2 phenotype will promote constructive dermal remodeling. Toward this end, a series of dextran-based bioabsorbable hydrogels are developed and self-crosslinkable dextran-isocyanatoethyl methacrylate-ethylamine (DexIEME) is identified as the potential scaffold...

Anticoagulant therapy is prescribed to millions of patients worldwide for the prevention and treatment of venous thrombosis. Evidence has indicated that edoxaban is a potential drug of oral anticoagulant in the acute treatment of venous thromboembolism. Hydrogen sulfide and homocysteine plasma concentration are indicators of cardiovascular and neurovascular disease risk factors that have attracted considerable attention for regulation of vascular health and homeostasis. However, the molecular mechanism of edoxaban‑mediated differences of hydrogen sulfide and homocysteine has not been investigated in the progression of venous thrombosis...

Lung functional impairment caused by acute pancreatitis (AP) is the primary contributor to AP‑associated mortality. Previous studies have reported that AP‑associated lung injury is associated with systemic inflammatory response syndrome and oxidative stress. In the present study, the protective effects of Danhong injection (DHI), a widely used Chinese Traditional Medicine preparation, on AP‑associated lung injury in rats was examined. The myeloperoxidase activity, malondiadelhyde level and superoxide dismutase activity determination demonstrated the anti‑inflammatory and anti‑oxidative properties of DHI...

Acute respiratory distress syndrome (ARDS) is a common and life‑threatening clinical syndrome, and seeking biomarkers of ARDS has been an area of continuing research. The present study hypothesized that alterations to certain immunogenic substances occur in injured lungs and are able to specifically bind with corresponding proteins in the blood, and that these proteins may be readily detected. To investigate this hypothesis, a rat model of ARDS was established by cecal ligation and puncture surgery, and an immunoproteomics approach, using serum as the primary antibody in a western blot analysis, was used with the aim of identifying immunogenic proteins in the injured lungs...

OBJECTIVE: Functional endonasal sinus surgery (FESS) is widely practiced and is considered a generally safe procedure. Skull base injuries occur in less than 1% of procedures and are typically associated with cerebrospinal fluid leaks. Rarely, skull base injuries might result in cerebral lesions. Here we present a series of four patients with iatrogenic perforating injuries of the anterior skull base and cerebral lesions after routine FESS. METHODS: Four patients with iatrogenic perforating cerebral lesions after routine FESS performed at other institutions were referred to a tertiary neurosurgery department within a 10-year period...

There is increasing recognition of the involvement of platelets in orchestrating inflammatory responses, driving the activation of neutrophils, monocytes and vascular endothelium, which, if poorly controlled, may lead to microvascular dysfunction. Importantly, hyperreactivity of platelets has been implicated in the pathogenesis of myocardial injury and the associated particularly high prevalence of acute cardiovascular events in patients with severe community-acquired pneumonia (CAP), of which Streptococcus pneumoniae (pneumococcus) is the most commonly encountered aetiologic agent...

Satellite cells are skeletal-muscle-specific stem cells that are activated by injury to proliferate, differentiate, and fuse to enable repair. SOX7, a member of the SRY-related HMG-box family of transcription factors is expressed in quiescent satellite cells. To elucidate SOX7 function in skeletal muscle, we knocked down Sox7 expression in embryonic stem cells and primary myoblasts and generated a conditional knockout mouse in which Sox7 is excised in PAX3(+) cells. Loss of Sox7 in embryonic stem cells reduced Pax3 and Pax7 expression...

Pharmacological inhibition of PSD-95 is a promising therapeutic strategy in the treatment of stroke, and positive effects of monomeric and dimeric PSD-95 inhibitors have been reported in numerous studies. However, whether therapeutic effects will generalize to other types of acute brain injury such as traumatic brain injury (TBI), which has pathophysiological mechanisms in common with stroke, is currently uncertain. We have previously found a lack of neuroprotective effects of dimeric PSD-95 inhibitors in the controlled cortical impact model of TBI in rats...

BACKGROUND: Proteinuria is a common finding in children. It may be due to a benign cause, but it can also represent early renal injury. Of children with persistent proteinuria noted in mass urine screening programs, 35% have a urine protein level greater than 100 mg/dl and many of them are associated with many underlying renal diseases. The aim of this study was to identify the etiology and prognosis of persistent proteinuria in children. METHODS: We collected data on urine protein from January 2011 to December 2016 in a tertiary medical center...
