The goals of this study were to quantify the effects of epinephrine on myocardial and cerebral blood flow during conventional cardiopulmonary resuscitation (CPR) and CPR with simultaneous chest compression-ventilation and to test the hypothesis that epinephrine would improve myocardial and cerebral blood flow by preventing collapse of intrathoracic arteries(More)
BACKGROUND Child growth retardation and malnutrition remain a matter of uttermost public concern in economically disadvantaged areas of China. The present study aimed to estimate the prevalence of protein-energy malnutrition with various anthropometric indices and examine its correlates in a large sample of poor rural minority children. METHODS A total of(More)
In the present study, the effects of lycium barbarum polysaccharide (LBP) on endothelial function in the two-kidney, one clip model of hypertension were observed. The results showed that the increase of blood pressure in hypertension rats (HR) could be prevented significantly by treatment with 10% LBP. In isolated aortic rings of LBP-treated rats, the(More)
Elevation of intrathoracic pressure during cardiopulmonary resuscitation generates carotid pressure and flow, but also increases intracranial pressure. This increase in intracranial pressure may limit cerebral blood flow. Therefore, we performed studies designed to quantify the extent of this transmission and to identify the mechanism of transmission of(More)
Whether blood flow during cardiopulmonary resuscitation (CPR) results from intrathoracic pressure fluctuations or direct cardiac compression remains controversial. From modeling considerations, blood flow due to intrathoracic pressure fluctuations should be insensitive to compression rate over a wide range, but dependent on the applied force and compression(More)
Background The optimal chemotherapy regimen administered currently with radiation in patients with stage III non-small cell lung cancer (NSCLC) remains unclear. A multicenter phase III trial was conducted to compare the efficacy of concurrent thoracic radiation therapy with either etoposide/cisplatin (EP) or carboplatin/paclitaxel (PC) in patients with(More)
DNA methylation is an epigenetic event involved in a variety array of processes that may be the foundation of genetic phenomena and diseases. DNA methyltransferase is a key enzyme for cytosine methylation in DNA, and can be divided into two functional families (Dnmt1 and Dnmt3) in mammals. All mammalian DNA methyltransferases are encoded by their own single(More)
BACKGROUND Ethnicity may possibly associate with different maternal child-rearing practices and child developmental problems. The aim of this study was to better understand epidemiological features and correlates of child behavior problems in a large sample of children in economically disadvantaged rural minority areas of China and to provide reference data(More)
This study investigated the effect of ginsenoside Rg1 on the functions of ex vivo cultivated endothelial progenitor cells (EPCs) and whether ginsenoside Rg1 prevented EPC senescence. EPCs isolated from peripheral blood from healthy volunteers were incubated with different concentrations of ginsenoside Rg1 and the effects were observed at different time(More)
