Gastrodin Prevents Cognitive Decline Related to Cardiopulmonary Bypass

描述
Cardiac surgery with cardiopulmonary bypass (CPB) is one of the most frequently performed operations. Neurobehavioral disorders, including neuropsychiatric and neuropsychological deficits, are a very frequently reported sequela of valve replacement or coronary artery bypass grafting (CABG) surgery. CPB is associated with significant cerebral morbidity. The incidence of cognitive decline related to CPB ranges from 20% to 80%, which may affect length of hospital stay, quality of life, the rehabilitation process, and work performance. Neurocognitive decline can present days to weeks after surgery and may remain a permanent disorder. Many pharmacologic strategies have been proposed or investigated for preventing post-CPB cognitive decline, but to our knowledge, none of these drugs has been systematically evaluated for efficacy in preventing post-CPB cognitive decline.
The causative parameters of cognitive dysfunction associated with CPB include cerebral ischemia secondary to either microemboli or hypoperfusion, intraoperative cerebrovascular risk factors such as the duration of CPB, inflammatory response, cerebral glutamine release, free radicals, and NO release.
Gastrodia elata, a famous Chinese medical herb, has effects on preventing ischemic brain injury, neuronal cell damage or apoptosis, suppressing inflammatory response, inhibiting glutamine receptors and nNOS, and scavenging free radicals. Gastrodin (4-[hydroxymethyl]phenyl-β-D-glucopyranoside), the primary active constituent of gastrodia elata, has been widely used for the treatment of paralysis, hemiplegia, headache, vertigo, and Alzheimer's disease. Based on its pharmacological effects, we postulated that gastrodin would attenuate the causative parameters of cognitive dysfunction related to CPB and would be an effective drug to prevent the decline as a result.
