Objective To evaluate the effects of different rates of remifentanil infusion on cardiovascular response to tracheal intubation in older patients. Methods Thirty ASA Ⅰ-Ⅲ patients aged 65-75 yrs weighing 50-80 kg scheduled for elective abdominal operation were randomly divided into 3 groups (n = 10 each) according to the remifentanil infusion rate: group A 0.05 ?g?kg-1?min-1; group B 0.1 ?g?kg-1?min-1 and group C 0.15 ?g ?kg-1?min-1. The patients were premedicated with intramuscular phenobarbital 0.1 g and atropine 0.5 mg. Radial artery and subclavian vein were cannulated for BP and CVP monitoring and blood sampling. ECG, BP, HR and SpO2 were monitored during anesthesia. After 10 min stabilization induction of anesthesia was commenced with remifentanil infusion for 10 min. Midazolam 0.1 mg?kg-1 was then given Ⅳ. Succinylcholine 1.5 mg?kg-1 was given to facilitate intubation after the patients lost consciousness. BP and HR were recorded immediately before induction of anesthesia (T0, baseline), immediately after intubation (T1 ) and at 2, 5 and 10 min after intubation (T2 ,T3 ,T4 ) . Cardiovascular intubation response was defined as increase in SP or HR by 15% of the baseline value within 2 min after intubation. Blood samples were taken at T0-4 for determination of plasma concentration of norepinephrine (NE) and epinephrine (E) by HPLC. Side effects such as chest wall rigidity and hypotension were also recorded. Results The cardiovascular intubation response rate was significantly higher in group A (80%) than in group B (10% ) and C (10% ) . The incidence of side effects was significantly higher in group C (70% ) than in group B (20%) and A. Plasma NE and E concentrations were significantly increased after intubation in group A (at T2-4) and B (at T2,3) as compared with baseline values at T0; while in group C only plasma NE concentration was significantly increased at T2 and T3 and there was no significant change in plasma E concentration after intubation. The plasma NE and E concentrations were significantly higher in group A (T2-4) and B (T2,3) than in group C. Conclusion The appropriate infusion rate of remifentanil for tracheal intubation is 0.10 ?g?kg-1 ?min-1 in older patients.

OBJECTIVE:To assess the effectiveness of 1,6—diphosphate fructose(FDP)in the treatment of heart failure(HF).METHODS:Biomedical databases,including Medline,Embase,Cochrane Controlled Trials Register,CBM and CNKI were searched.Clinical trials were screened according to the inclusion criteria formulated beforehand,quality assessments and meta anylysis of included studies were carried out.RESULTS:14 randomized controlled trial were included,and all of them were carried out in China.Jadad score of the studies were all 1.None of the 14 trials carried out by follow-up domization for long-term effect evulation Meta-analysis of 14 trials showed that FDP can increase effective rate in the treatment of HF,and OR(95%CI)was 3.79(2.58,5.57).5 studies showed that FDP can increase cardic index,and WMD(95%CI)was 0.40(0.34,0.46).6 studies showed that FDP can increase ejection fraction(EF)with WMD(95%CI)8.31(5.51,11.11).4 studies showed that FDP can decrease left ventricular end systolic and diastolic diameter,and WMD was—3.25(—4.74,—1.76)and—3.75(—6.94,—0.56).No long-term effects were reported by the included studies.CONCLUSIONS:According to present evidence,FDP can increase the treatment effective rate when added to the basic treatment of HF.FDP can improve heart function and lefe ventricular construction showed by the indicators.However,the poor quality of the studies decreased the persuasion of the results.Large-scale and well-designed RCTs with enough follow-ups should be carried out to provide further evidence for the use of FDP.

OBJECTIVE:To systematically review the efficacy,safety and economy of acarbose versus metformin in the treat-ment of type 2 diabetes,and provide evidence-based reference for the clinical treatment. METHODS:Retrieved from PubMed, Medline,CJFD,Wanfang database,VIP database,randomized controlled trails (RCT) about acarbose (test group) versus metfor-min(control group)in the treatment of type 2 diabetes were collected. Meta-analysis was performed by using Rev Man 5.2 statis-tics software,and the decision tree model was used to do the cost-effectiveness analysis by using TreeAge Pro 2011.1.0.12.1 soft-ware. RESULTS:A total of 8 RCT,involving 418 patients. Results of Meta-analysis showed 2 h postprandial blood glucose (2 h PG)in test group [MD=-2.21,95%CI(-2.92,-1.51),P<0.001] was lower than that of control group,there was no signifi-cant diffcrencc in the glycated hemoglobin levels[MD=0.02,95%CI(-0.38,0.34),P=0.91],fasting blood glucose level[MD=0.05,95%CI(0.91,1.01),P=0.92] and incidence of adverse reactions [OR=1.84,95%CI(0.80,4.24),P=0.92] between 2 groups. Results of decision tree analysis showed the cost-effectiveness ratio in test group and control group was 847.15 and 272.53,respec-tively;and incremental cost-effectiveness ratio was 13 776. CONCLUSIONS:Acarbose shows an obvious advantage on decreasing the 2 h PG of type 2 diabetes,however,pharmacoeconomics shows metformin has higher economic effects. Due to the limit of methodological quality,large-scale and high quality RCT are required for further validation of the conclusions.
