Objective To investigate the incidence, causes, management and prognosis of atrial fibrillation (AF) after operation of esophagus cancer(EC)and lung cancer(LC). Methods The patients of postoperative AF following EC and LC surgery between December 2004 and May 2006 were taken into EC group and LC group. Results AF occurred in 27 patients ( 11.2%) of EC and in 18 patients (5.6%) of LC. The duration of operating and the level of urine catecholamine within the first two days after operation in the EC group were higher than those of the LC group (P0.05). All patients had been cured. Conclusions The EC predominate over the LC in the incidence of AF after operation; the early medicine treatment needs to be advisable to patients, and the patients of LC can be treated with removing causes at first.

Objective: To investigate the protective effect of Xuesaitong(total saponins of sanchi) on lower extremity ischemical reperfusion injury.Methods: To observe PBN-spin bulky adducts signal of lower extremity ischemical reperfusion of rabbit by using electron spin resonance technology and electron spin resonance promoter N-tert-butyl-2-phenylnitrone(PBN).Results: The signal intensity is correlated with time,compared with ischemia for 2 hours,the signal intensity of ischemia for 4 hours increased apparently.Xuesaitong would quench PBN-spin bulky adducts signal significantly.Conclusion: Xuesaitong have protective effect on lower extremity ischemia-reperfusion injury.

Object Under the premise of protecting periodicals published in Republic of China, these periodicals were processed with digitalization for the purpose of being utilized in a easy way. Methods Oracle 9i database software was used to establish database table structure. Periodicals published in Republic of China were selected, periodicals pictures were processed and the literature subjects were indexed before databases retrieval system of these periodicals was made and published. Results A full text data base retrieval system containing 20 kinds of periodicals published in Republic of China was established, to provide both retrieval from multi-angles and picture browsing of the full text. Conclusion Digitalization technique is a way of reproducible protection and utilization of periodicals published in Republic of China.
