[Endovascular stent-graft repair for penetrating atherosclerotic ulcer of the descending aorta].
To summarize the clinical experience and effectiveness of endovascular stent-graft placement for the treatment of penetrating atherosclerotic ulcer of the descending thoracic aorta. ⋯ Penetrating atherosclerotic ulcer can leads to intramural hematoma, dissection, aneurysmal dilatation, pseudoaneurysm, or aortic rupture. Therefore it should be treated once diagnosed. Endovascular stent-graft placement may be an effective treatment for penetrating atherosclerotic ulcer, especially in patients with poor condition.

[Favorable effect of chitosan sustained-release FK506 incorporated conduits on axonal regeneration in rat sciatic nerve].
To investigate the efficacy of 3 mm gap bridging repairing neurotmesis with chitosan sustained-release FK506 incorporated conduits. ⋯ Remaining 3 mm gap bridging repairing rat sciatic nerve with chitosan sustained-release FK506 incorporated conduits, which stabilize for more than 2 months before degradation in vivo, can significantly promote nerve regeneration and facilitate function recovery without adverse effects.

[Accuracy of preoperative magnetic resonance imaging in prediction of pathological stage and circumferential resection margin in rectal cancer].
To evaluate the accuracy of preoperative magnetic resonance imaging (MRI) in prediction of pathological staging and involvement of circumferential resection margin (CRM) in rectal cancer. ⋯ Preoperative MRI provides poor predictive data as to subsequent pathologic tumor and mesorectal node stage, but does produce reliable prediction of clear CRM.

[Prefrontal and superior temporal lobe hyperactivity as a biological substrate of generalized anxiety disorders].
To explore the potential mechanism of generalized anxiety disorders (GAD). ⋯ Dysfunction of superior temporal lobe and dorsal prefrontal cortex, characterized by hyperactivity in response to outer stimuli, may play an important role in the psychopathologic mechanism of GAD.

[Cardioprotective effects of sodium ferulate mediated by nitric oxide on ischemia-reperfusion injured myocardium: experiment with isolated rat hearts].
To investigate the cardioprotective effects of sodium ferulate (SF) mediated by nitric oxide on ischemia-reperfusion injured myocardium. ⋯ SF pretreatment significantly improves the releasing of NO, decreases oxygen free radicals, and relieves myocardial ischemia reperfusion injury. The opening of the ATP-sensitive potassium channels induced by the cGMP way of NO activation may be an important pathway in the cardioprotective effects of SF pretreatment.
