To evaluate the effects of esmolol hydroehloride on hemodynamies during tracheal intubation. Method: One hundred patients undergoing elective cerebral, thoracic or abdominal operations, were randomly divided into three groups: Group A, Group B and Group C, which were injected I. V. esmolol 1.0mg/kg, 2.0mg/kg and normal saline 10ml respectively before induction of anesthesia. SP, DP, HR and RPP were recorded immediately before administration, before intubation and 1,2,3,5 and 10 min after intubation. Result: HR in Group A and Group B was signifcantly slower than in Group C, especially 3 min and 10 min after intubation(P

ObjectiveTo investigate the prevalence and distributing feature of atrial fibrillation (AF) in Xinjiang Kazaks adult population.MethodsFour-stage selected random samples aged 30-89 years from Tacheng,Yili and Aletai were analyzed.An epidemical study of AF was performed including inquiring medical history,recording electrocardiogram and auscultation. ResultsA total of 22 514 adults were surveyed.The prevalence of AF in Xinjiang Kazaks adult population was 0.37％,which was increasing with aging.The prevalence was higher in men than in women (0.5％ vs 0.2％,P ＜0.01 ).In AF patients,23 was valvular AF.Ischemic stroke was the most frequent type and the stroke rate in the patients with AF was significantly higher than that without AF (6.0％ vs 1.2％,P ＜ 0.01 ).ConclusionsThe prevalence of AF in Xinjiang Kazaks adult population is lower than the reported national prevalence but patients with AF in this population would not like to take the necessary medicine. Therefore,the control of AF need to be reinforced.

Discipline evaluation is an effective and boosting mean of constructing high level key disciplines,but if there is something wrong or flaws with the means,indicators,process,ways,the effect may be just the opposite.Therefore,establishing scientific evaluation system is an important premise to construct key disciplines,promote discipline development and improve the level of academy construction.This article which is aimed at current situation of discipline evaluation system,puts forward some major principles to establish scientific evaluation for discipline,it is significant to play a right evaluation guide and promote the discipline construction.Carrying out discipline evaluation needs to have right guiding thought,establish and perfect indicator system of discipline evaluation,strengthen orderly management of evaluation work,offer scope to stimulate function of discipline evaluation.Only in these ways,can we construct a batch of characteristic and competitive key disciplines.
