AIMS Major guidelines recommend lowering systolic blood pressure (SBP) to <140 mmHg in all hypertensives, but evidence is missing whether this is beneficial in (i) uncomplicated hypertensives, (ii) grade 1 hypertensives, and (iii) elderly hypertensives. Providing this missing evidence is important to justify efforts and costs of aggressive therapy in all(More)
Many literatures have proven that postoperative cognitive dysfunction (POCD) was very common in old patients after the injury of acute myocardial ischemia-reperfusion (AMIR) clinically such as the off-pump coronary artery bypass surgery (OPCAB) without definite mechanism; however, reports on the animal experiments were rarely seen. We hypothesized that AMIR(More)
Lead exposure in children has received increasing attention from scientists and public health institutions worldwide. Deficiencies of nutritional essential metals can increase the hazard from lead exposure by enhancing absorption and toxicity of dietary lead. Lead, as a ubiquitous toxicity metal, may interact metabolically with nutritional essential metals.(More)
Therapeutic hypercapnia has the potential for neuroprotection after global cerebral ischemia. Here we further investigated the effects of different degrees of acute systemic hypoxia in combination with hypercapnia on brain damage in a rat model of hypoxia and ischemia. Adult wistar rats underwent unilateral common carotid artery (CCA) ligation for 60 min(More)
