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.

Comparative StudyComparison of epinephrine and Shen-Fu injection on resuscitation outcomes in a porcine model of prolonged cardiac arrest.
Epinephrine has been used as a first-choice vasopressor drug for cardiac arrest (CA) since 1974. However, the administration of epinephrine is controversial. This study aims to compare the effects of Shen-Fu injection (SFI) and epinephrine on resuscitation outcomes in a porcine model of prolonged CA. ⋯ SFI shortened the time to ROSC and decreased the number of shocks, similar to epinephrine. However, SFI improved oxygen metabolism, and produced a better hemodynamic status compared with epinephrine. SFI might be a potentially vasopressor drug for the treatment of CA.

Spontaneous brain activity in chronic smokers revealed by fractional amplitude of low frequency fluctuation analysis: a resting state functional magnetic resonance imaging study.
Nicotine is primarily rsponsible for the highly addictive properties of cigarettes. Similar to other substances, nicotine dependence is related to many important brain regions, particular in mesolimbic reward circuit. This study was to further reveal the alteration of brain function activity during resting state in chronic smokers by fractional amplitude of low frequency fluctuation (fALFF) based on functional magnetic resonance imaging (fMRI), in order to provide the evidence of neurobiological mechanism of smoking. ⋯ In smokers during rest, the activity of addiction related regions were increased and the activity of smoking feeling, memory, related regions were also changed. The resting state activity changes in many regions were associated with the cumulative amount of nicotine intake and the severity of nicotine dependence.

Human infection with a novel avian-origin influenza A (H7N9) virus: serial chest radiographic and CT findings.
Rapidly progressive pneumonia infection with H7N9 virus is a novel disease, and limited information is available concerning serial chest radiographic and computed tomography (CT) findings. The aim of this study was to evaluate the changes in serial radiologic findings in patients with H7N9 pneumonia. ⋯ The most common radiologic findings at presentation are multifocal or diffuse areas of consolidation and GGOs in H7N9 pneumonia. HRCT in sequence can show more changes in rapid progression of disease and a slow decrease of both size and opacity of the lesions plays an important role in the evaluation of H7N9 pneumonia.

Effect of different resuscitation strategies on post-resuscitation brain damage in a porcine model of prolonged cardiac arrest.
The choice of a defibrillation or a cardiopulmonary resuscitation (CPR)-first strategy in the treatment of prolonged cardiac arrest (CA) is still controversial. The purpose of this study was to compare the effects of defibrillation or CPR administered first on neurological prognostic markers in a porcine model of prolonged CA. ⋯ Defibrillation first may result in a shorter time to ROSC and lower biochemical markers of brain injury in a porcine model of 8-minute CA due to VF, but the choice of different resuscitation strategies did not affect the rate of ROSC and 24-hour survival.
