OBJECTIVE Oxygen desaturation is common among patients with sleep apnea. This study was designed to evaluate the methods used to express the severity of oxygen desaturation in patients with obstructive sleep apnea hypopnea syndrome. METHODS The oxygen saturation data of 215 patients [suspected of having obstructive sleep apnea (OSA)] studied at the Sleep(More)
Growth hormone (GH) plays an important role in animal growth and development, and the growth hormone gene can be considered as a candidate gene for studying the weight in goats. The function of GH gene has been intensively studied in cattle and pigs, while in goats the study is still rare. In this paper 224 goats including LuBei White goat, Boer goat,(More)
OBJECTIVE To study clinical characteristics of pediatric SARS cases in Beijing. METHODS Eighteen pediatric cases with SARS diagnosed on admission were analyzed. The cases were admitted to Beijing Children's Hospital and Ditan Hospital (pediatric ward) from April 8 to May 12. RESULTS The 18 children aged 5 months to 15 years (10 male and 8 female) had(More)
This paper deals with a new approach based on Q-learning for solving the problem of mobile robot path planning in complex unknown static environments. As a computational approach to learning through interaction with the environment, reinforcement learning algorithms have been widely used for intelligent robot control, especially in the field of autonomous(More)
OBJECTIVE Resveratrol, a phytoalexin, is reported to activate AMP-activated protein kinase (AMPK) in vascular cells. Activation of AMPK induces vasorelaxation to lower blood pressure (BP). Whether resveratrol via activation of AMPK decreases, BP remains unknown. METHODS Male wild-type (WT) mice and mice deficient in AMPKα2 (AMPKα2(-/-)) were fed with(More)
OBJECTIVE To evaluate the significance of several Dermatophagoides pteronyssinus allergen extracts for skin prick test (SPT) in patients allergic to Dermatophagoides pteronyssinus. METHODS Two hundred and nineteen patients enrolled in Peking Union Medical College Hospital underwent SPT and serum specific IgE assay to detect the Dermatophagoides(More)
In the past decades, studies have shown that a balance between regulatory T cells (Tregs) and T helper 17 (Th17) cells plays a major role in autoimmune/inflammatory diseases as well as pregnancy complications. Decreased number and function of Tregs, and increased number of Th17 cells which often have an opposed effect of Tregs, are associated with these(More)
The polymorphism of goat growth hormone gene in 5'-region in 274 goats including Lubei white goat, introducted Boer goat, pure bred Boer goat , hybrid generation 1 of LuBei white goat and Boer goat , backcross of hybrid generation 1 and Boer goat were detected by PCR-SSCP with two different pairs of primers. The result showed that in 26-239bp most of the(More)
This study aims to observe and evaluate the use of remifentanil in conscious sedation and analgesia for the safety and comfort of patients undergoing short-term endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (EST).Sixty-eight patients who underwent ERCP and EST were randomly divided into two groups: research group and(More)
