[Effect of sevoflurane postconditioning on spinal cord ischemia reperfusion injury via the release of oxygen free radicals in rabbits].
To investigate whether postconditioning with sevoflurane could alleviate spinal cord ischemia reperfusion injury in rabbits, and whether the beneficial effect is dependent on oxygen free radicals. ⋯ Our study demonstrates that sevoflurane postconditioning against spinal cord ischemia injury via the release of oxygen free radicals in rabbits.

[Epimedium-derived flavonoids prevent ovariectomy-induced osteoporosis in rats independent of its enhancement in intestinal calcium absorption].
To test our hypothesis whether a group of flavonoids (FE) derived from herbal Epimedium exerted its prevention of estrogen-deficiency-induced osteoporosis mainly through an enhancement in intestinal calcium absorption. ⋯ Independent of intestinal calcium absorption, FE inhibited bone resorption, stimulated bone formation and accordingly prevented osteoporosis without hyperplastic effect on uterus in the OVX rat model.

Randomized Controlled Trial[Effect of a novel analgesic disposable urinary catheter in prevention of restlessness caused by catheter-related bladder discomfort in general anesthesia patients in recovery period].
To investigate the effect of a novel analgesic disposable urinary catheter invented by the authors in prevention of restlessness caused by catheter-related bladder discomfort (CRBD) in general anesthesia patients in anesthesia recovery period. ⋯ The catheter inserting after the induction of anesthesia is an element related to the restlessness in anesthesia recovery period and other serious postoperative complications. The novel analgesic disposable urinary catheter effectively prevents CRBD-caused restlessness in general anesthesia patients in the anesthesia recovery period.

[Evaluating the feature of hypoglycemia detected by continuous glucose monitoring system during temporary continuous subcutaneous insulin infusion in type 2 diabetes patients].
To use continuous glucose monitoring system (CGMS) to investigate the features of hypoglycemia in control of hyperglycemia in T2DM patients by continuous subcutaneous insulin infusion (CSII) and to study the influencing factors of hypoglycemia. ⋯ (1) Hypoglycemia detected by CGMS occurs in about 1/3 of the type 2 diabetes patients at the early stage of CSII therapy. (2) In addition of MBG and insulin pump basal rate, glycemic excursion is related closely to hypoglycemia.

[Effects of sympathetic nerve stimulation on connexin43 and ventricular arrhythmias during acute myocardial ischemia: experiment with rats].
To investigate the effects of sympathetic nerve stimulation (SNS) on connexin43 (Cx43) and ventricular arrhythmias during acute myocardial ischemia (MI). ⋯ SNS promotes ventricular arrhythmias by promoting Cx43 degradation, and sympathetic nerve stimulation preconditioning inhibits ventricular arrhythmias by preventing Cx43 dephosphorylation.
