Objective: To summarize and analyze the early outcomes and clinical experience in 1198 patients undergone off-pump coronary artery bypass (OPCAB). Methods: This multi-center report covers 15 different institutes in China from October 1996 to May 2002. The ratio of OPCAB to conventional coronary artery bypass grafting (cCABG) was 85.2%. The mean age was (61.6?9.0) years. 77.3% patients were male and 22.7% were female. There were 34.6% patients with myocardial infarction, 58.2% with unstable angina pectoris, 18.7% with left main lesion, 76.9% with triple-vessel disease, 1.5% was redo surgery, and 9.9% emergent or urgent surgery. The mean left ventricular ejection fraction was 0.56?0.17. Results: The number of distal anastomosis was 3.1?0.9. IMA was used in 65.6% patients and radial artery was used in 18.0%. 13.5% OPCAB was combined with TMLR. IABP was used in 5.2% patients. The hospital mortality was 1.2%. The morbidity included 0.4% peri-operative myocardial infarction, 0.3% heart failure, 1.2% fatal arrhythmia, 2.0% pulmonary complications, 1.2% neurotic disorder, 0.7% renal dysfunction, 1.0% reopen for bleeding, and 0.6% delayed wound healing. Conclusion: OPCAB surgery is a safe and feasible procedure with good early results. Its late outcomes need further follow-up. OPCAB requires certain special skills and methods in practice so a specific training course should be designed.

Objective To explore the antitumor mechanism of xianhe yanling recipe( XHYLR ). Methods The mechanism of action of 241 compounds contained in the Chinese medicine, XHYLR was studied by using computational pharmacological. Methods including molecular docking,biotechnology network,chemical space technology and the prediction of absorption,distribution,metabolism,excretion and toxicity( ADME/T). Results Most of the compounds in XHYLR had good drug-like properties. Distribution of 241 compounds in chemical space also revealed that these compounds showed similar anti-tumor activity. It suggested that the prescription of XHYLR was reasonable. The phenomena that one molecular interacted with multiple target proteins and several molecules interact with one target protein were observed in XHYLR. For example,the COX-2 interacted with 40 micromolecules,and catechin interacted with five targets including COX-2. Conclusion These results are helpful for understanding the complicated mechanism of anti-tumor activity of XHYLR.
