Effects of resolvin D1 on inflammatory responses and oxidative stress of lipopolysaccharide-induced acute lung injury in mice.
A variety of inflammatory mediators and effector cells participate together in acute lung injury, and lead to secondary injury that is due to an inflammatory cascade and secondary diffuse lung parenchyma injury. Inflammation is associated with an oxidative stress reaction, which is produced in the development of airway inflammation, and which has positive feedback on inflammation itself. Resolvin D1 can reduce the infiltration of neutrophils, regulate cytokine levels and reduce the inflammation reaction, and thereby promote the resolution of inflammation. The purpose of this study is to investigate the effects of resolvin D1 on an inflammatory response and oxidative stress during lipopolysaccharide (LPS)-induced acute lung injury. ⋯ Resolvin D1 displays potent anti-inflammatory actions by regulating cytokines, inhibiting aberrant neutrophil recruitment and stimulating apoptosis of neutrophils. Resolvin D1 can also relieve the injury due to oxidative stress. The mechanisms might be related to increase HO-1 expression.

ReviewExtracorporeal blood therapy in sepsis and acute respiratory distress syndrome: the "purifying dream".
To discuss the rationale, hypothesis, modality of extracorporeal blood purification (EBP) techniques for the critically ill animal models or patients, and to summarize the experimental and clinical studies with inconsistent data which explored the EBP's efficacy in the areas of critical care medicine. ⋯ It is not now to conclude that EBP intervention can purify septic or ARDS patients with high clinical efficacy from current experimental and clinical practice. Prospective, randomized controlled, and well-designed clinical or experimental studies and most suitable EBP modalities should be further developed.

Kyphoplasty versus vertebroplasty for the treatment of malignant vertebral compression fractures caused by metastases: a retrospective study.
There are few comparative studies regarding kyphoplasty (KP) and vertebroplasty (VP) for the treatment of painful vertebral compression fractures (VCF) in patients with cancer. The purpose of this study is to retrospectively compare KP with VP in pain improvement, cement leakage incidence, and the cost of treatment of malignant VCF. ⋯ VP and KP are both effective in providing pain relief for patients with cancer-related VCF. KP provides no greater degree of pain improvement. KP is associated with a lower rate of cement leakage compared with VP. VP is associated with lower cost and shorter postoperative hospital stay in China.
