[Protective effect of urinary trypsin inhibitor on injury after intestinal ischemia-reperfusion: experiment with rats].
To investigate the mechanism of the injury of intestinal mucosal induced by intestinal ischemia-reperfusion and the protect effects of Urinary Trypsin Inhibitor (UTI). ⋯ Intestinal ischemia-reperfusion may result in intestinal mucosal damage, the mechanism may be involved in the release of abnormal TNF-alpha, NO, reactive oxygen and activated PMN; UTI can protect intestinal mucosal against intestinal ischemia-reperfusion injury, which may be associated with inhibiting the release of NO and TNF-a, ameliorating reactive oxygen damage, decreasing the aggregation and activation of PMN.

[Electrophysiological properties of outward voltage-gated potassium channels of neural stem cells from adult rat hippocampus].
To explore the electrophysiological properties of outward voltage-gated potassium channels of neural stem cells (NSCs) from adult rat hippocampus. ⋯ The cultured NSCs of adult rat hippocampus express at least three kinds of outward voltage-gated potassium channels, I(DR), I(A), and BKCa in vitro.

[Study of pulmonary parenchyma MRI with flow sensitive alternating inversion recovery].
To evaluate the feasibility of pulmonary parenchyma perfusion imaging with flow sensitive alternating inversion recovery (FAIR), which is noninvasive and doesn't necessitate injection of contrast agents. ⋯ Pulmonary perfusion with FAIR is feasible, but the perfusion of right and left lung may be different on certain slice due to spin saturation effect. FAIR is also sensitive to reflect perfusion heterogeneity due to gravity effect.

To investigate the clinical characteristics and treatment of cervical spondylotic amyotrophy. ⋯ Cervical spondylotic amyotrophy is a rare type of cervical spondylotic disorder, it is easily misdiagnosed because it is confused with motor neuron disease. MRI and electromyography can help to diagnose. The mechanism of cervical spondylotic amyotrophy maybe is that compression of anterior horn of spinal cord or ischemic injury of spinal cord. Surgical treatment can help to improve muscle power, prognosis of single segment is better than that of multiple segments.

Randomized Controlled Trial[Effect of target-controlled infusion sufentanil in different doses combined with nitrogen monoxide inhalation on hemodynamics and postoperative recovery].
To investigate the effect of target-controlled infusion sufentanil in different doses combined with inhalation anesthesia at 0.9 minimum alveolar concentration (MAC) on the intraoperative hemodynamics and postoperative recovery of spontaneous breathing. ⋯ When the concentration of inhalation anesthetic is at 0.9 MAC, the target plasma sufentanil concentration of 0.3 ng/ml is adequate in anesthesia. If sufentanil infusion was terminated 50 min before the end of surgery, the patients can recover safely and quickly.
