[Effect of anticoagulation and thrombolysis on circulation endothelial cells and endothelial function after acute inferior vena cava thrombosis in rats].
To explore the functions and adhesive properties of circulating endothelial cells after acute thrombosis in rats. ⋯ A combination of heparin and urokinase for the treatment of acute inferior caval venous thrombosis may effectively maintain the endothelial integrity of vein wall and decrease the fibroblast proliferation of thrombosed vein. Adhesion to caval vein wall is relatively lower during an early post-thrombotic period.

Randomized Controlled Trial Comparative Study[Effects of different ventilation mode on pulmonary function during minor operation of general anesthesia with SLIPA laryngeal mask].
To retrospectively analyze the effects of different ventilation modes on pulmonary function during minor operation of general anesthesia with streamlined liner of the pharynx airway (SLIPA) laryngeal mask and assess its safety of spontaneous respiration during general anesthesia. ⋯ Neither mechanical ventilation mode nor spontaneous respiration ventilation mode has any effect upon pulmonary function by during minor operation of general anesthesia with SLIPA laryngeal mask. Spontaneous respiration can offer a sufficient supply of oxygen but it carries the risk of CO(2) accumulation.

[Sevoflurane postconditioning attenuates myocardial apoptosis in isolated rat hearts via a modulation of Bcl-2 family proteins].
To explore the effects of sevoflurane postconditioning on ischemic/reperfused myocardial apoptosis. ⋯ Sevoflurane postconditioning may improve myocardial functions, reduce infarct size and attenuate myocardial apoptosis. And the modulated expression of apoptotic proteins plays an important role in sevoflurane-induced myocardial protection.

Randomized Controlled Trial Comparative Study[Comparison of effects in puerpera and fetus with ephedrine and phenylephrine during a cesarean delivery].
To compare the different effects in fetus and puerpera with an equivalent dose of ephedrine (E) and phenylephrine (Ph) for maintaining maternal blood pressure near baseline during spinal anesthesia for a cesarean delivery. ⋯ Phenylephrine may be more ideal for treating the hypotension of spinal anesthesia for a cesarean delivery. It corrects hypotension following spinal anesthesia, improves fetal oxygen supply and demand balance but induces no metabolic excitation in fetus as compared with ephedrine.

[Building an effective nonlinear three-dimensional finite-element model of human thoracolumbar spine].
To build an effective nonlinear three-dimensional finite-element (FE) model of T(11)-L(3) segments for a further biomechanical study of thoracolumbar spine. ⋯ With the advantages of high geometric and mechanical similarity and complete thoracolumbar, hexahedral meshes, nonlinear finite element model may facilitate the impact loading test for a further dynamic analysis of injury mechanism for thoracolumbar burst fracture.
