RESUMO
According to the principles of constructing evaluation index system in designed experiments,we formulated the content,designed the weights and established the evaluation index system in designed experiments based on analytical hierarchy process and Delphi.This system can assess students' cognition and attitudes,abilities of innovation,practice,teamwork and cooperation as well as scientific writing skills by providing objective and comprehensive evaluation criteria.
RESUMO
Objective To evaluate the myocardial protective effect of dexmedetomidine during non-cardiac surgery in patients with coronary heart disease.Methods Eighty ASAⅡor Ⅲ patients with coronary heat disease (NYHA Ⅱ or Ⅲ)aged 43-76 yr weighing 52-80 kg scheduled for elective upper abdominal surgery were randomly divided into 2 groups(n=40 each)：control group(group C)and dexmedetomidine group(group D).Anesthesia was induced with etomidate 0.25 mg／kg，sufentanil 0.5 μg／kg and vecuronium 0.1 mg／kg.The patients were tracheal intubated and mechanically ventilated.A loading dose of dexmedetomidine 1μg/kg was injected intravenously 10 min before induction followed by infusion at 0.4 μg·kg-1·h-1 until the end of operation in group D.While equal volume of normal saline was given in group C.BIS was maintained at 40-49.Blood samples were taken before induction and at the end of operation for determination of serum concenlrations of IL-6，TNF-α，cardiac troponin Ⅰ(cTnI)and glycogen phosphorylase BB(GP-BB).The adverse cardiovascular events were recorded during operation.Results The serum concentrations of IL-6，TNF-α，cTnI and GP-BB and incidences of tachycardia and myocardial ischemia were significantly lower，while the incidences of bradycardia highcr in group D than in group C (P<0.05).Conclusion Dexmedetomidine Can exert the myocardial protective effect during non-cardiac surgery in patients with coronary heart disease and the mechanism may be related to the inhibition of the release of pro-inflammatory cytokines.
RESUMO
Objective:To study the effect of midnight-noon ebb-flow acupoint selection on rheumatoid arthritis. Methods:120 cases of patients with rheumatoid arthritis were randomly divided into three groups:midnight-noon ebb-flow acupoint selection group,acupuncture by differentiation of symptoms and signs group,integrative group of midnight-noon ebb-flow acupoint selection and acupuncture by differentiation of symptoms and signs group. Results:In the midday-midnight flowing of qi-blood acupuncture group of 40 cases,11 cases were improved obviously,11cases were improved,9cases were improved slightly,9 cases were ineffective,the total effective rate was 77.5%. In the acupuncture by differentiation of symptoms and signs group of 40 patients,10 cases were improved significantly,11 cases were improved,11 cases were improved moderate,8 cases were ineffective,the total effective rate was 80.0%. In integrated group of midnight-noon ebb-flow acupoint selection and acupuncture by differentiation of symptoms and signs group of 40 patients,15 cases were improved significantly,13 cases were improved,10 cases were improved moderate,2 cases were ineffective,the total effective rate was 95.0%. Curative effect of the integrative group was better than that of other two groups(P
