Molecular biological analysis of genotyping and phylogeny of severe acute respiratory syndrome associated coronavirus.
SARS-CoV is the causative agent of severe acute respiratory syndrome (SARS) which has been associated with outbreaks of SARS in Guangdong, Hong Kong and Beijing of China, and other regions worldwide. SARS-CoV from human has shown some variations but its origin is still unknown. The genotyping and phylogeny of SARS-CoV were analyzed and reported in this paper. ⋯ The results mentioned above suggest that SARS-CoV is responding to host immunological pressures and experiencing variation which provide clues, information and evidence of molecular biology for the clinical pathology, vaccine developing and epidemic investigation.

Randomized Controlled Trial Clinical TrialEffects of acupoints TENS on heat pain threshold in normal subjects.
To delineate the influence of transcutaneous electrical nerve stimulation (TENS) on heat pain threshold and vibration threshold in human. ⋯ The effect of TENS on the acupoint is to reduce pain but not tactile (specifically vibration) sensibility.

The association analysis of FcepsilonRIbeta with allergic asthma in a Chinese population.
To investigate the link between the polymorphism of -109 and Glu237 in the high-affinity IgE receptor beta (FcepsilonRIbeta) gene and susceptibility to allergic asthma in a Chinese population. ⋯ These results suggest that the Gly237 variant of the FcepsilonRIbeta gene is involved in the development of allergic asthma. The -109C/T and Glu237Gly polymorphisms are two of the genetic factor identified thus far, which affect total plasma IgE levels of allergic asthma patients in a Chinese population.

Randomized Controlled Trial Comparative Study Clinical TrialPatient controlled intravenous analgesia with tramadol for labor pain relief.
To evaluate the safety and analgesic efficacy of patient controlled intravenous analgesia (PCIA) with tramadol, and to compare its benefits and risks with combined spinal-epidural analgesia (CSEA)+ patient controlled epidural analgesia (PCEA). ⋯ PCIA with tramadol is now a useful alternative when patients are not candidates for CSEA for labor, or do not want to have a neuraxial block anesthesia. However, sometimes it may not provide satisfactory analgesic effect.

The effect of theophylline on sleep-disordered breathing in patients with stable chronic congestive heart failure.
To determine the prevalence of sleep-disordered breathing in patients with stable, optimally treated chronic congestive heart failure and the effect of short-term oral theophylline therapy on periodic breathing in these patients. ⋯ The prevalence of sleep-disordered breathing (mainly periodic respiration or cheyne-stokes respiration with central sleep apnea) is high in patients with stable chronic congestive heart failure. The sleep-disordered breathing episodes are associated with severe nocturnal arterial blood oxyhemoglobin desaturation and excessive arousals. In these patients, oral theophylline therapy may reduce the number of episodes of central apnea and hypopnea and the duration of arterial oxyhemoglobin desaturation during nocturnal sleep.
