An optimization study of the ultra-short period for HRV analysis at rest and post-exercise.

Background: Ultra-short-term heart rate variability (HRV) analysis (< 5 min) has been extensively growing in the field of exercise performance for autonomic assessment. However, the validation of ultra-short-term HRV was unclear in the recovery period of exercise. This study aimed to elucidate the agreement between ultra-short-term HRV (0-30 s, 0-1 min, 0-2 min, 0-3 min, 0-4 min) and standard short-term HRV (5 min) and to explore the optimal recording duration under rest and post-exercise conditions.

Supraannular aortic replacement for severe valve detachment attributable to Behçet's disease.

The occurrence of aortic regurgitation (AR) attributable to Behçet's disease is rare, but it brings extraordinary complexity to surgical intervention due to the high risk of postoperative morbidity as the result of valve dehiscence or pseudoaneurysms caused by fragile aortic structures and inflamed tissue. The high rate of prosthetic valve detachment after aortic valve replacement is one of the most serious consequences of aortic regurgitation in Behçet's disease, which results in severe aortic annular destruction, presenting a big challenge to cardiac surgeons. Under this condition, a conventional surgical technique is necessary to be modified for improving postoperative prognosis of patients.

[Clinical and experimental studies of the dynamic changes in neuropeptides after trauma].

Dynamic changes of contents of beta-endorphin, leu-enkephalin and oxytocin in plasma were determined in seventeen fracture patients with shock, fascial space syndromes, or infection postoperation. There was significant rise of contents in beta-endorphin and leu-enkephalin but not in oxytocin after trauma, Of those accompanied by infection postoperation, beta-endorphin and oxytocin remained high. The contents of beta-endorphin and enkephalin decreased gradually in non-infectious group, but were still higher than normal.
