Administration of adenosine triphosphate or adenosine is an important clinical trial in diagnosis and treatment of arrhythmias. It may not only terminate the paroxysmal supraventricular tachycardia and the specific type of ventricular tachycardia, but also identify the mechanism of majority of arrhythmias. Otherwise, It is also a useful diagnostic test for sick sinus sydrome and a reliable methos to assess radiofrequency catheter ablation.

Objective To investigate the impact of hs-CRP and IVUS on major adverse cardiac event in patients who after coronary artery intermediate lesions stent implantation.Methods 82 patients with clinical diagnosis of coronary heart disease who had a segmental stenosis degree is 40％ ～ 70％ in one major coronary artery on coronary angiography,all of the patients do intravascular ultrasound,patients had minimal lumen area(MLA) of intermediate lesions ≤ 4mm2( the left main coronary artery)or≤ 6mm2( left main coronary artery) who received percutaneous coronary intervention(PCI),and the patients were divided into 2 groups,hs-CRP rise group(≥3mg/L) and hs-CRP normal group(＜3mg/L),compared the rate between the two groups in hospital and follow up periods by typical angina,nonfatal myocardial infarction,cardiac death and target-vessel revascularization and other major adverse cardiac events (MACE).Results The rate on major adverse cardiac event in hs-CRP rise group was significantly higher than the normal group(P ＜0.01 );the restenosis rate in hs-CRP rise group higher than hs-CRP normal group(P ＜0.01 ).Conclusion hs-CRP could predict the rate on major adverse cardiac event in patients with after coronary artery intermediate lesions stent implantation,the patients of hs-CRP rise group should strengthen antiplatelet,anti-inflammatory treatment etc.

Objective To evaluate the cost-effectiveness of Morphine-midazolam, propofol and midazolam used for sedation in patients with mechanical ventilation. Methods Ninety-three patients with mechanically ventila-Morphine-midazolam group:priming dose 0.05 mg/kg and 0.05 mg/kg of morphine and midazolam,then continuous The index of ideal level of sedation was on the Ramsay scale. The sedation time, the time from discontinuation to ex-tubation, sedation costs, blood pressure were measured. Results The time in midazolam group (6.0±2.4) h was longer than that of propofol (4.6±1.7) h (P<0.01), but there was no significant relationship between morphine-midazolam group (5.6±2.7) h and midazolam group (4.6±1.7) h (P>0.05). The sedation costs in morphine-mi-dazolam group (101.7±20.4) yuan were lower than those of midazolam group (127.7±21.3) yuan (P<0.05) and propofol group(199.7±65.9) yuan (P<0.01). The ratio of hypotension in propofol group (35.4%, 11/31) hap-pened more frequent than that of midazolam group (3.2%, 1/31) (P<0.01) and morphine-midazolam group (9.7%, 3/31) (P<0.05). Conclusions Morphine-midazolam is a safe, effective and economic drug compared with midazolam and propofol used for sedation in patients with mechanical ventilation.
