Interactions between remote ischemic conditioning and post-stroke sleep regulation

《医学前沿（英文）》 2021年 第15卷 第6期   页码 867-876 doi: 10.1007/s11684-021-0887-9

摘要： Sleep disturbances are common in patients with stroke, and sleep quality has a critical role in the onset and outcome of stroke. Poor sleep exacerbates neurological injury, impedes nerve regeneration, and elicits serious complications. Thus, exploring a therapy suitable for patients with stroke and sleep disturbances is imperative. As a multi-targeted nonpharmacological intervention, remote ischemic conditioning can reduce the ischemic size of the brain, improve the functional outcome of stroke, and increase sleep duration. Preclinical/clinical evidence showed that this method can inhibit the inflammatory response, mediate the signal transductions of adenosine, activate the efferents of the vagal nerve, and reset the circadian clocks, all of which are involved in sleep regulation. In particular, cytokines tumor necrosis factor α (TNFα) and adenosine are sleep factors, and electrical vagal nerve stimulation can improve insomnia. On the basis of the common mechanisms of remote ischemic conditioning and sleep regulation, a causal relationship was proposed between remote ischemic conditioning and post-stroke sleep quality.

Effects of modafinil on vestibular function during 24 hour sleep deprivation

《医学前沿（英文）》 2007年 第1卷 第2期   页码 226-229 doi: 10.1007/s11684-007-0044-0

摘要： The aim of this research was to investigate the effects of modafinil, a new wake-promoting agent, on vestibular function during 24 h sleep deprivation (SD) so as to provide experimental evidence for the rational use of this drug among air crew. Eight young, healthy male volunteers were exposed to two 24 h periods of continuous wakefulness during the crossover experiment. Initially, 200 mg dose of modafinil was given, and one week later, a matching placebo was administered. The SD time started from 08:00 of the first day to 08:00 of the second day. Drugs were given at 0:00 on the second day. Vestibular function was tested at 21:00 on the first day and 1, 3, 5, 7 h after drug administration. The accuracy of saccade tracking and gains in visual-vestibular optokinetic reflex (VVOR) and optokinetic nystagmus (OKN) in the placebo group decreased during 24 h SD, especially at 01:00 05:00 on the second day, while OKN gains in the modafinil group increased significantly. There were no significant differences in the other vestibular functional indices between the modafinil group and placebo group. The 24 h SD can influence vestibular function to a certain degree, but modafinil may improve OKN.

Identification of surgical patients at high risk of OSAS using the Berlin Questionnaire to detect potential high risk of adverse respiratory events in post anesthesia care unit

摘要：

Obstructive sleep apnea syndrome (OSAS) increases the risk of post-surgery complications. This study uses Berlin Questionnaire (BQ) to identify Chinese adult surgical patients who are at a high risk of OSAS and to determine if the BQ could be used to detect potential high risk of adverse respiratory events in the post anesthesia care unit (PACU). Results indicated that only 11.4% of the patients were considered at a high risk of OSAS. Age and body mass index are the key factors for the risk of OSAS prevalence in China and also gender specific. Furthermore, the incidence of adverse respiratory events in the PACU was higher in patients with high risk of OSAS than others (6.8% vs. 0.9%, <0.001). They also stayed longer than others in the PACU (95±28 min vs. 62±19 min, <0.001). Age, high risk for OSAS, and smoking were independent risk factors for the occurrence of adverse respiratory events in the PACU. The BQ may be adopted as a screening tool for anesthesiologists in China to identify patients who are at high risk of OSAS and determine the potential risk of developing postoperative respiratory complications in the PACU.
